2How to get started (GigE G2)

2.1 Introduction

This guide shows you:

• How to install the required hardware (see Section 2.2)

• How to install the required software (see Section 2.3) and configure the Network AdapterCard (see Section 2.4 and Section 2.5)

• How to acquire your first images and how to modify camera settings (see Section 2.6)

• A Starter Guide [MAN051] can be downloaded from the Photonfocus support page. Itdescribes how to access Photonfocus GigE cameras from various third-party tools.

2.2 Hardware Installation

The hardware installation that is required for this guide is described in this section.

The following hardware is required:

• PC with Microsoft Windows OS (XP, Vista, Windows 7)

• A Gigabit Ethernet network interface card (NIC) must be installed in the PC. The NICshould support jumbo frames of at least 9014 bytes. In this guide the Intel PRO/1000 GTdesktop adapter is used. The descriptions in the following chapters assume that such anetwork interface card (NIC) is installed. The latest drivers for this NIC must be installed.

• Photonfocus GigE camera.

• Suitable power supply for the camera (see in the camera manual for specification) whichcan be ordered from your Photonfocus dealership.

• GigE cable of at least Cat 5E or 6.

Photonfocus GigE cameras can also be used under Linux.

Photonfocus GigE cameras work also with network adapters other than the IntelPRO/1000 GT. The GigE network adapter should support Jumbo frames.

Do not bend GigE cables too much. Excess stress on the cable results in transmis-sion errors. In robots applications, the stress that is applied to the GigE cable isespecially high due to the fast movement of the robot arm. For such applications,special drag chain capable cables are available.

The following list describes the connection of the camera to the PC (see in the camera manualfor more information):

4. Select a valid IP address for selected camera (see Fig. 2.12). There should be noexclamation mark on the right side of the IP address. Click on Ok in the Set IP Addressdialog. Select the camera in the GEV Device Selection dialog and click on Ok.

Figure 2.12: Setting IP address

5. Finish the configuration process and connect the camera to PF_GEVPlayer .

Figure 2.13: PF_GEVPlayer is readily configured

6. The camera is now connected to the PF_GEVPlayer . Click on the Play button to grabimages.

An additional check box DR1 appears for DR1 cameras. The camera is in dou-ble rate mode if this check box is checked. The demodulation is done in thePF_GEVPlayer software. If the check box is not checked, then the camera out-puts an unmodulated image and the frame rate will be lower than in doublerate mode.

20

If no images can be grabbed, close the PF_GEVPlayer and adjust the JumboFrame parameter (see Section 2.3) to a lower value and try again.

Figure 2.14: PF_GEVPlayer displaying live image stream

7. Check the status LED on the rear of the camera.

. The status LED light is green when an image is being acquired, and it is red whenserial communication is active.

8. Camera parameters can be modified by clicking on GEV Device control (see Fig. 2.15). Thevisibility option Beginner shows most the basic parameters and hides the more advancedparameters. If you don’t have previous experience with Photonfocus GigE cameras, it isrecommended to use Beginner level.

3 Product Specification

The general specification and features of the camera are listed in the following sections.

The G2 postfix in the camera name indicates that it is the second release of Pho-tonfocus GigE cameras. The first release had the postfix GB and is not recom-mended for new designs. The main advantages of the G2 release compared withthe GB release are the smaller size, better I/O capabilities and the support of 24 Vvoltage supply.

Fig. 3.9 shows the bayer filter arrangement on the pixel matrix in the MV1-D1312C cameraseries. The numbers in the figure represents pixel position x, pixel position y.

The fix bayer pattern arrangement has to be considered when the ROI configu-ration is changed or the MROI feature is used (see 4.3). It depends on the linenumber in which an ROI starts. An ROI can start at an even or an odd line num-ber.

4Functionality

This chapter serves as an overview of the camera configuration modes and explains camerafeatures. The goal is to describe what can be done with the camera. The setup of theMV1-D1312(IE/C) series cameras is explained in later chapters.

If not otherwise specified, the DR1-D1312(IE) camera series has the same func-tionality as the MV1-D1312(IE/C) camera series. In most cases only the MV1-D1312(IE/C) cameras are mentionend in the text.

4.1 Image Acquisition

4.1.1 Readout Modes

The MV1-D1312 CMOS cameras provide two different readout modes:

Sequential readout Frame time is the sum of exposure time and readout time. Exposure timeof the next image can only start if the readout time of the current image is finished.

Simultaneous readout (interleave) The frame time is determined by the maximum of theexposure time or of the readout time, which ever of both is the longer one. Exposuretime of the next image can start during the readout time of the current image.

Readout Mode MV1-D1312 Series

Sequential readout available

Simultaneous readout available

Table 4.1: Readout mode of MV1-D1312 Series camera

The following figure illustrates the effect on the frame rate when using either the sequentialreadout mode or the simultaneous readout mode (interleave exposure).

Sequential readout mode For the calculation of the frame rate only a single formula applies:frames per second equal to the inverse of the sum of exposure time and readout time.

Simultaneous readout mode (exposure time < readout time) The frame rate is given by thereadout time. Frames per second equal to the inverse of the readout time.

Simultaneous readout mode (exposure time > readout time) The frame rate is given by theexposure time. Frames per second equal to the inverse of the exposure time.

The simultaneous readout mode allows higher frame rates. However, if the exposure timegreatly exceeds the readout time, then the effect on the frame rate is neglectable.

In simultaneous readout mode image output faces minor limitations. The overalllinear sensor reponse is partially restricted in the lower grey scale region.

When changing readout mode from sequential to simultaneous readout modeor vice versa, new settings of the BlackLevelOffset and of the image correctionare required.

Sequential readout

By default the camera continuously delivers images as fast as possible ("Free-running mode")in the sequential readout mode. Exposure time of the next image can only start if the readouttime of the current image is finished.

4.1.2 Readout Timing

Sequential readout timing

By default, the camera is in free running mode and delivers images without any externalcontrol signals. The sensor is operated in sequential readout mode, which means that thesensor is read out after the exposure time. Then the sensor is reset, a new exposure starts andthe readout of the image information begins again. The data is output on the rising edge ofthe pixel clock. The signals FRAME_VALID (FVAL) and LINE_VALID (LVAL) mask valid imageinformation. The signal SHUTTER indicates the active exposure period of the sensor and is shownfor clarity only.

These terms will be used also in the timing diagrams of Section 4.4.

4.1.3 Exposure Control

The exposure time defines the period during which the image sensor integrates the incominglight. Refer to Section 3.3 for the allowed exposure time range.

4.1.4 Maximum Frame Rate

The maximum frame rate depends on the exposure time and the size of the image (see Section4.3.)

The maximal frame rate with current camera settings can be read out from theproperty FrameRateMax (AcquisitionFrameRateMax in GigE cameras).

4.2 Pixel Response

4.2.1 Linear Response

The camera offers a linear response between input light signal and output grey level. This canbe modified by the use of LinLog®as described in the following sections. In addition, a lineardigital gain may be applied, as follows. Please see Table 3.2 for more model-dependentinformation.

Black Level Adjustment

The black level is the average image value at no light intensity. It can be adjusted by thesoftware. Thus, the overall image gets brighter or darker. Use a histogram to control thesettings of the black level.

In CameraLink® cameras the black level is called "BlackLevelOffset" and in GigEcameras "BlackLevel".

4.2.2 LinLog®

Overview

The LinLog® technology from Photonfocus allows a logarithmic compression of high lightintensities inside the pixel. In contrast to the classical non-integrating logarithmic pixel, theLinLog® pixel is an integrating pixel with global shutter and the possibility to control thetransition between linear and logarithmic mode.

In situations involving high intrascene contrast, a compression of the upper grey level regioncan be achieved with the LinLog® technology. At low intensities each pixel shows a linearresponse. At high intensities the response changes to logarithmic compression (see Fig. 4.10).The transition region between linear and logarithmic response can be smoothly adjusted bysoftware and is continuously differentiable and monotonic.

LinLog® is controlled by up to 4 parameters (Time1, Time2, Value1 and Value2). Value1 and Value2correspond to the LinLog® voltage that is applied to the sensor. The higher the parametersValue1 and Value2 respectively, the stronger the compression for the high light intensities. Time1and Time2 are normalised to the exposure time. They can be set to a maximum value of 1000,which corresponds to the exposure time.

Examples in the following sections illustrate the LinLog® feature.

LinLog1

In the simplest way the pixels are operated with a constant LinLog® voltage which defines theknee point of the transition.This procedure has the drawback that the linear response curvechanges directly to a logarithmic curve leading to a poor grey resolution in the logarithmicregion (see Fig. 4.12).

LinLog2

To get more grey resolution in the LinLog® mode, the LinLog2 procedure was developed. InLinLog2 mode a switching between two different logarithmic compressions occurs during theexposure time (see Fig. 4.13). The exposure starts with strong compression with a highLinLog®voltage (Value1). At Time1 the LinLog®voltage is switched to a lower voltage resulting ina weaker compression. This procedure gives a LinLog®response curve with more greyresolution. Fig. 4.14 and Fig. 4.15 show how the response curve is controlled by the threeparameters Value1, Value2 and the LinLog®time Time1.

Settings in LinLog2 mode, enable a fine tuning of the slope in the logarithmicregion.

LinLog3

To enable more flexibility the LinLog3 mode with 4 parameters was introduced. Fig. 4.16 showsthe timing diagram for the LinLog3 mode and the control parameters..

4.3 Reduction of Image Size

With Photonfocus cameras there are several possibilities to focus on the interesting parts of animage, thus reducing the data rate and increasing the frame rate. The most commonly usedfeature is Region of Interest (ROI).

4.3.1 Region of Interest (ROI)

Some applications do not need full image resolution (e.g. 1312 x 1082 pixels). By reducing theimage size to a certain region of interest (ROI), the frame rate can be increased. A region ofinterest can be almost any rectangular window and is specified by its position within the fullframe and its width (W) and height (H). Fig. 4.18, Fig. 4.19 and Fig. 4.20 show possibleconfigurations for the region of interest, and Table 4.3 presents numerical examples of howthe frame rate can be increased by reducing the ROI.

Both reductions in x- and y-direction result in a higher frame rate.

The minimum width of the region of interest depends on the camera model. Formore details please consult Table 4.5 and Table 4.7.

The minimum width must be positioned symmetrically towards the vertical cen-ter line of the sensor as shown in Fig. 4.18, Fig. 4.19 and Fig. 4.20). A list ofpossible settings of the ROI for each camera model is given in Table 4.7.

Colour models only: the vertical start position and height of every ROI should bean even number number to have the correct Bayer pattern in the output image(see also Section 3.4).

. It is recommended to re-adjust the settings of the shading correction each timea new region of interest is selected.

4.3.2 ROI configuration

In the MV1-D1312(IE/C) camera series the following restrictions have to be respected for theROI configuration:

• The minimum width (w) of the ROI is camera model dependent, consisting of 288 pixel inthe MV1-D1312(IE/C)-40 camera, of 416 pixel in the MV1-D1312(IE/C)-80 camera and of544 pixel in the MV1-D1312(IE/C)-100 camera.

• The region of interest must overlap a minimum number of pixels centered to the left andto the right of the vertical middle line of the sensor (ovl).

• DR1-D1312(IE) cameras only: the height must be an even number.

For any camera model of the MV1-D1312(IE/C) camera series the allowed ranges for the ROIsettings can be deduced by the following formula:

xmin = max(0, 656 + ovl− w)xmax = min(656− ovl, 1312− w) .

where "ovl" is the overlap over the middle line and "w" is the width of the region of interest.

Any ROI settings in x-direction exceeding the minimum ROI width must be mod-ulo 32.

4.3.3 Calculation of the maximum frame rate

The frame rate mainly depends on the exposure time and readout time. The frame rate is theinverse of the frame time.

The maximal frame rate with current camera settings can be read out from theproperty FrameRateMax.

fps = 1tframe

Calculation of the frame time (sequential mode)

tframe ≥ texp + tro

Typical values of the readout time tro are given in table Table 4.8 and Table 4.9. Calculation ofthe frame time (simultaneous mode)

The calculation of the frame time in simultaneous read out mode requires more detailed datainput and is skipped here for the purpose of clarity.

4.3.4 Multiple Regions of Interest

The MV1-D1312(IE/C) camera series can handle up to 512 different regions of interest. Thisfeature can be used to reduce the image data and increase the frame rate. An applicationexample for using multiple regions of interest (MROI) is a laser triangulation system withseveral laser lines. The multiple ROIs are joined together and form a single image, which istransferred to the frame grabber.

An individual MROI region is defined by its starting value in y-direction and its height. Thestarting value in horizontal direction and the width is the same for all MROI regions and isdefined by the ROI settings. The maximum frame rate in MROI mode depends on the numberof rows and columns being read out. Overlapping ROIs are allowed. See Section 4.3.3 forinformation on the calculation of the maximum frame rate.

Fig. 4.22 compares ROI and MROI: the setups (visualized on the image sensor area) aredisplayed in the upper half of the drawing. The lower half shows the dimensions of theresulting image. On the left-hand side an example of ROI is shown and on the right-hand sidean example of MROI. It can be readily seen that resulting image with MROI is smaller than theresulting image with ROI only and the former will result in an increase in image frame rate.

ROI and MROI not only increase the frame rate but also the amount of data tobe processed is reduced. This increases the performance of your image procesingsystem.

4.4 Trigger and Strobe

4.4.1 Introduction

The start of the exposure of the camera’s image sensor is controlled by the trigger. The triggercan either be generated internally by the camera (free running trigger mode) or by an externaldevice (external trigger mode).

This section refers to the external trigger mode if not otherwise specified.

In external trigger mode (TriggerMode=On), the trigger is applied according to the value of theTriggerSource property (see Section 4.4.2). The trigger signal can be configured to be activehigh or active low (property TriggerActivation). When the frequency of the incoming triggersis higher than the maximal frame rate of the current camera settings, then some trigger pulseswill be missed. A missed trigger counter counts these events. This counter can be read out bythe user. The input and output signals of the power connector are connected to theProgrammable Logic Controller (PLC) which allows powerful operations of the input andoutput signals (see Section 5.6).

A suitable trigger breakout cable for the Hirose 12 pol. connector can be orderedfrom your Photonfocus dealership.

The exposure time in external trigger mode can be defined by the setting of the exposure timeregister (camera controlled exposure mode) or by the width of the incoming trigger pulse(trigger controlled exposure mode) (see Section 4.4.4).

An external trigger pulse starts the exposure of one image. In Burst Trigger Mode however, atrigger pulse starts the exposure of a user defined number of images (see Section 4.4.6).

The start of the exposure is shortly after the active edge of the incoming trigger. An additionaltrigger delay can be applied that delays the start of the exposure by a user defined time (seeSection 4.4.5). This is often used to start the exposure after the trigger to a flash lightingsource.

4.4.2 Trigger Source

The trigger signal can be configured to be active high or active low by the TriggerActivation(category AcquisitionControl) property. One of the following trigger sources can be used:

Free running The trigger is generated internally by the camera. Exposure starts immediatelyafter the camera is ready and the maximal possible frame rate is attained, ifAcquisitionFrameRateEnable is disabled. Settings for free running trigger mode:TriggerMode = Off. In Constant Frame Rate mode (AcquisitionFrameRateEnable = True),exposure starts after a user-specified time has elapsed from the previous exposure start sothat the resulting frame rate is equal to the value of AcquisitionFrameRate.

56

Software Trigger The trigger signal is applied through a software command (TriggerSoftwarein category AcquisitionControl). Settings for Software Trigger mode: TriggerMode = Onand TriggerSource = Software.

Line1 Trigger The trigger signal is applied directly to the camera by the power supplyconnector through pin ISO_IN1 (see also Section A.1). A setup of this mode is shown inFig. 4.31 and Fig. 4.32. The electrical interface of the trigger input and the strobe outputis described in Section 5.5. Settings for Line1 Trigger mode: TriggerMode = On andTriggerSource = Line1.

PLC_Q4 Trigger The trigger signal is applied by the Q4 output of the PLC (see also Section 5.6).Settings for PLC_Q4 Trigger mode: TriggerMode = On and TriggerSource = PLC_Q4.

Some trigger signals are inverted. A schematic drawing is shown in Fig. 4.30.

4.4.3 Trigger and AcquisitionMode

The relationship between AcquisitionMode and TriggerMode is shown in Table 4.12. WhenTriggerMode=Off, then the frame rate depends on the AcquisitionFrameRateEnable property (seealso under Free running in Section 4.4.2).

The ContinuousRecording and ContinousReadout modes can be used if more thanone camera is connected to the same network and need to shoot images simul-taneously. If all camera are set to Continous mode, then all will send the packetsat same time resulting in network congestion. A better way would be to setthe cameras in ContinuousRecording mode and save the images in the memory ofthe IPEngine. The images can then be claimed with ContinousReadout from onecamera at a time avoid network collisions and congestion.

4.4.4 Exposure Time Control

Depending on the trigger mode, the exposure time can be determined either by the camera orby the trigger signal itself:

Camera-controlled Exposure time In this trigger mode the exposure time is defined by thecamera. For an active high trigger signal, the camera starts the exposure with a positivetrigger edge and stops it when the preprogrammed exposure time has elapsed. Theexposure time is defined by the software.

Trigger-controlled Exposure time In this trigger mode the exposure time is defined by thepulse width of the trigger pulse. For an active high trigger signal, the camera starts theexposure with the positive edge of the trigger signal and stops it with the negative edge.

Trigger-controlled exposure time is not available in simultaneous readout mode.

External Trigger with Camera controlled Exposure Time

In the external trigger mode with camera controlled exposure time the rising edge of thetrigger pulse starts the camera states machine, which controls the sensor and optional anexternal strobe output.

This signal is clocked into theFPGA which leads to a jitter of tjitter. The pulse can be delayed by the time ttrigger−delay whichcan be configured by a user defined value via camera software.

The trigger pulse from the internal camera control starts also the strobe control state machines.The strobe can be delayed by tstrobe−delay with an internal counter which can be controlled bythe customer via software settings. The strobe offset delay tstrobe−delay results then from thesynchronous design of the FPGA state machines. A second counter determines the strobeduration tstrobe−duration(strobe-duration). For a robust system design the strobe output is alsoisolated from the camera electronic which leads to an additional delay of td−iso−output. Section4.4.6 gives an overview over the minimum and maximum values of the parameters.

External Trigger with Pulsewidth controlled Exposure Time

In the external trigger mode with Pulsewidth controlled exposure time the rising edge of thetrigger pulse starts the camera states machine, which controls the sensor. The falling edge ofthe trigger pulse stops the image acquisition. Additionally the optional external strobe outputis controlled by the rising edge of the trigger pulse. Timing diagram Fig. 4.34 shows thedetailed timing for the external trigger mode with pulse width controlled exposure time.

The timing of the rising edge of the trigger pulse until to the start of exposure and strobe isequal to the timing of the camera controlled exposure time (see Section 4.4.4). In this modehowever the end of the exposure is controlled by the falling edge of the trigger Pulsewidth:

The falling edge of the trigger pulse is delayed by the time td−iso−input which is results from thesignal isolator. This signal is clocked into the FPGA which leads to a jitter of tjitter. The pulse isthen delayed by ttrigger−delay by the user defined value which can be configured via camerasoftware. After the trigger offset time ttrigger−offset the exposure is stopped.

4.4.5 Trigger Delay

The trigger delay is a programmable delay in milliseconds between the incoming trigger edgeand the start of the exposure. This feature may be required to synchronize to external strobewith the exposure of the camera.

4.4.6 Burst Trigger

The camera includes a burst trigger engine. When enabled, it starts a predefined number ofacquisitions after one single trigger pulse. The time between two acquisitions and the numberof acquisitions can be configured by a user defined value via the camera software. The bursttrigger feature works only in the mode "Camera controlled Exposure Time".

The burst trigger signal can be configured to be active high or active low. When the frequencyof the incoming burst triggers is higher than the duration of the programmed burst sequence,then some trigger pulses will be missed. A missed burst trigger counter counts these events.This counter can be read out by the user.

The burst trigger mode is only available when TriggerMode=On. Trigger source is determined bythe TriggerSource property.The timing diagram of the burst trigger mode is shown in Fig. 4.35. The timing of the"external trigger pulse input" until to the "trigger pulse internal camera control" is equal tothe timing in the section Fig. 4.34. This trigger pulse then starts after a user configurable bursttrigger delay time tburst−trigger−delay the internal burst engine, which generates n internaltriggers for the shutter- and the strobe-control. A user configurable value defines the timetburst−period−time between two acquisitions.

4.4.7 Software Trigger

The software trigger enables to emulate an external trigger pulse by the camera softwarethrough the serial data interface. It works with both burst mode enabled and disabled. Assoon as it is performed via the camera software, it will start the image acquisition(s),depending on the usage of the burst mode and the burst configuration. The trigger modemust be set to external Trigger (TriggerMode = On).

4.4.8 Strobe Output

The strobe output is an isolated output located on the power supply connector that can beused to trigger a strobe. The strobe output can be used both in free-running and in triggermode. There is a programmable delay available to adjust the strobe pulse to your application.

The strobe output needs a separate power supply. Please see Section 5.5, Fig.4.31 and Fig. 4.32 for more information.

4.6 Image Correction

4.6.1 Overview

The camera possesses image pre-processing features, that compensate for non-uniformitiescaused by the sensor, the lens or the illumination. This method of improving the image qualityis generally known as ’Shading Correction’ or ’Flat Field Correction’ and consists of acombination of offset correction, gain correction and pixel interpolation.

Since the correction is performed in hardware, there is no performance limita-tion of the cameras for high frame rates.

The offset correction subtracts a configurable positive or negative value from the live imageand thus reduces the fixed pattern noise of the CMOS sensor. In addition, hot pixels can beremoved by interpolation. The gain correction can be used to flatten uneven illumination or tocompensate shading effects of a lens. Both offset and gain correction work on a pixel-per-pixelbasis, i.e. every pixel is corrected separately. For the correction, a black reference and a greyreference image are required. Then, the correction values are determined automatically in thecamera.

Do not set any reference images when gain or LUT is enabled! Read the follow-ing sections very carefully.

Correction values of both reference images can be saved into the internal flash memory, butthis overwrites the factory presets. Then the reference images that are delivered by factorycannot be restored anymore.

4.6.2 Offset Correction (FPN, Hot Pixels)

The offset correction is based on a black reference image, which is taken at no illumination(e.g. lens aperture completely closed). The black reference image contains the fixed-patternnoise of the sensor, which can be subtracted from the live images in order to minimise thestatic noise.

Offset correction algorithm

After configuring the camera with a black reference image, the camera is ready to apply theoffset correction:

1. Determine the average value of the black reference image.

2. Subtract the black reference image from the average value.

3. Mark pixels that have a grey level higher than 1008 DN (@ 12 bit) as hot pixels.

4. Store the result in the camera as the offset correction matrix.

5. During image acquisition, subtract the correction matrix from the acquired image andinterpolate the hot pixels (see Section 4.6.2).

How to Obtain a Black Reference Image

In order to improve the image quality, the black reference image must meet certain demands.

The detailed procedure to set the black reference image is described in Section6.5.

• The black reference image must be obtained at no illumination, e.g. with lens apertureclosed or closed lens opening.

• It may be necessary to adjust the black level offset of the camera. In the histogram of theblack reference image, ideally there are no grey levels at value 0 DN after adjustment ofthe black level offset. All pixels that are saturated black (0 DN) will not be properlycorrected (see Fig. 4.38). The peak in the histogram should be well below the hot pixelthreshold of 1008 DN @ 12 bit.

• Camera settings may influence the grey level. Therefore, for best results the camerasettings of the black reference image must be identical with the camera settings of theimage to be corrected.

4.6.3 Gain Correction

The gain correction is based on a grey reference image, which is taken at uniform illuminationto give an image with a mid grey level.

Gain correction is not a trivial feature. The quality of the grey reference imageis crucial for proper gain correction.

Gain correction algorithm

After configuring the camera with a black and grey reference image, the camera is ready toapply the gain correction:

1. Determine the average value of the grey reference image.

2. Subtract the offset correction matrix from the grey reference image.

3. Divide the average value by the offset corrected grey reference image.

4. Pixels that have a grey level higher than a certain threshold are marked as hot pixels.

5. Store the result in the camera as the gain correction matrix.

6. During image acquisition, multiply the gain correction matrix from the offset-correctedacquired image and interpolate the hot pixels (see Section 4.6.2).

Gain correction is not a trivial feature. The quality of the grey reference imageis crucial for proper gain correction.

Gain correction always needs an offset correction matrix. Thus, the offset correc-tion always has to be performed before the gain correction.

How to Obtain a Grey Reference Image

In order to improve the image quality, the grey reference image must meet certain demands.

The detailed procedure to set the grey reference image is described in Section6.5.

• The grey reference image must be obtained at uniform illumination.

Use a high quality light source that delivers uniform illumination. Standard illu-mination will not be appropriate.

• When looking at the histogram of the grey reference image, ideally there are no greylevels at full scale (4095 DN @ 12 bit). All pixels that are saturated white will not beproperly corrected (see Fig. 4.41).

• Camera settings may influence the grey level. Therefore, the camera settings of the greyreference image must be identical with the camera settings of the image to be corrected.

4.6.4 Corrected Image

Offset, gain and hot pixel correction can be switched on separately. The followingconfigurations are possible:

• No correction

• Offset correction only

• Offset and hot pixel correction

• Hot pixel correction only

• Offset and gain correction

• Offset, gain and hot pixel correction

4.7 Digital Gain and Offset

There are two different gain settings on the camera:

Gain (Digital Fine Gain) Digital fine gain accepts fractional values from 0.01 up to 15.99. It isimplemented as a multiplication operation. Colour camera models only: There isadditionally a gain for every RGB colour channel. The RGB channel gain is used tocalibrate the white balance in an image, which has to be set according to the currentlighting condition.

Digital Gain Digital Gain is a coarse gain with the settings x1, x2, x4 and x8. It is implementedas a binary shift of the image data where ’0’ is shifted to the LSB’s of the gray values. E.g.for gain x2, the output value is shifted by 1 and bit 0 is set to ’0’.

The resulting gain is the product of the two gain values, which means that the image data ismultiplied in the camera by this factor.

Digital Fine Gain and Digital Gain may result in missing codes in the output im-age data.

A user-defined value can be subtracted from the gray value in the digital offset block. If digitalgain is applied and if the brightness of the image is too big then the interesting part of theoutput image might be saturated. By subtracting an offset from the input of the gain block itis possible to avoid the saturation.

4.8 Grey Level Transformation (LUT)

Grey level transformation is remapping of the grey level values of an input image to newvalues. The look-up table (LUT) is used to convert the greyscale value of each pixel in an imageinto another grey value. It is typically used to implement a transfer curve for contrastexpansion. The camera performs a 12-to-8-bit mapping, so that 4096 input grey levels can bemapped to 256 output grey levels. The use of the three available modes is explained in thenext sections. Two LUT and a Region-LUT feature are available in the MV1-D1312 camera series(see Section 4.8.4).

For the MV1-D1312-240-CL camera series, bits 0 & 1 of the LUT input are fixed to0.

The output grey level resolution of the look-up table (independent of gain,gamma or user-definded mode) is always 8 bit.

There are 2 predefined functions, which generate a look-up table and transfer itto the camera. For other transfer functions the user can define his own LUT file.

Some commonly used transfer curves are shown in Fig. 4.43. Line a denotes a negative orinverse transformation, line b enhances the image contrast between grey values x0 and x1.Line c shows brightness thresholding and the result is an image with only black and white greylevels. and line d applies a gamma correction (see also Section 4.8.2).

4.10 Crosshairs (monochrome models only)

4.10.1 Functionality

The crosshairs inserts a vertical and horizontal line into the image. The width of these lines isone pixel. The grey level is defined by a 12 bit value (0 means black, 4095 means white). Thisallows to set any grey level to get the maximum contrast depending on the acquired image.The x/y position and the grey level can be set via the camera software. Figure Fig. 4.56 showstwo examples of the activated crosshairs with different grey values. One with white lines andthe other with black lines.

4 Functionality

The x- and y-positon is absolute to the sensor pixel matrix. It is independent on the ROI, MROIor decimation configurations. Figure Fig. 4.57 shows two situations of the crosshairsconfiguration. The same MROI settings is used in both situations. The crosshairs however is setdifferently. The crosshairs is not seen in the image on the right, because the x- and y-position isset outside the MROI region.

4.11 Image Information and Status Line (not available for DR1-D1312(IE))

There are camera properties available that give information about the acquired images, suchas an image counter, average image value and the number of missed trigger signals. Theseproperties can be queried by software. Alternatively, a status line within the image data can beswitched on that contains all the available image information.

4.11.1 Counters and Average Value

Image counter The image counter provides a sequential number of every image that is output.After camera startup, the counter counts up from 0 (counter width 24 bit). The countercan be reset by the camera control software.

Real Time counter The time counter starts at 0 after camera start, and counts real-time in unitsof 1 micro-second. The time counter can be reset by the software in the SDK (Counterwidth 32 bit).

Missed trigger counter The missed trigger counter counts trigger pulses that were ignored bythe camera because they occurred within the exposure or read-out time of an image. Infree-running mode it counts all incoming external triggers (counter width 8 bit / no wraparound).

Missed burst trigger counter The missed burst trigger counter counts trigger pulses that wereignored by the camera in the burst trigger mode because they occurred while the camerastill was processing the current burst trigger sequence.

Average image value The average image value gives the average of an image in 12 bit format(0 .. 4095 DN), regardless of the currently used grey level resolution.

4.11.2 Status Line

If enabled, the status line replaces the last row of the image with camera status information.Every parameter is coded into fields of 4 pixels (LSB first) and uses the lower 8 bits of the pixelvalue, so that the total size of a parameter field is 32 bit (see Fig. 4.58). The assignment of theparameters to the fields is listed in Table 4.19.

The status line is available in all camera modes.

4.12 Test Images

Test images are generated in the camera FPGA, independent of the image sensor. They can beused to check the transmission path from the camera to the frame grabber. Independent fromthe configured grey level resolution, every possible grey level appears the same number oftimes in a test image. Therefore, the histogram of the received image must be flat.

A test image is a useful tool to find data transmission errors that are caused mostoften by a defective cable between camera and frame grabber in CameraLink®

cameras. In Gigabit Ethernet cameras test images are mostly useful to test thegrabbing software.

The analysis of the test images with a histogram tool gives the correct result at aresolution of 1024 x 1024 pixels only.

4.12.1 Ramp

Depending on the configured grey level resolution, the ramp test image outputs a constantpattern with increasing grey level from the left to the right side (see Fig. 4.59).

Figure 4.59: Ramp test images: 8 bit output (left), 10 bit output (middle),12 (right)

4.12.2 LFSR

The LFSR (linear feedback shift register) test image outputs a constant pattern with apseudo-random grey level sequence containing every possible grey level that is repeated forevery row. The LFSR test pattern was chosen because it leads to a very high data toggling rate,which stresses the interface electronic.In the histogram you can see that the number of pixels of all grey values are the same.

Please refer to application note [AN026] for the calculation and the values of the LFSR testimage.

4.12.3 Troubleshooting using the LFSR

To control the quality of your complete imaging system enable the LFSR mode, set the camerawindow to 1024 x 1024 pixels (x=0 and y=0) and check the histogram. If your frame grabberapplication does not provide a real-time histogram, store the image and use a graphic softwaretool to display the histogram.

In the LFSR (linear feedback shift register) mode the camera generates a constantpseudo-random test pattern containing all grey levels. If the data transmission is error free, the

4.12 Test Images 89

4 Functionality

Figure 4.60: LFSR (linear feedback shift register) test image

histogram of the received LFSR test pattern will be flat (Fig. 4.61). On the other hand, anon-flat histogram (Fig. 4.62) indicates problems, that may be caused either by the a defectivecamera or by problems in the grabbing software.

4.13 Double Rate (DR1-D1312(IE) only)

The Photonfocus DR1 cameras use a proprietary modulation algorithm to cut the data rate byalmost a factor of two. This enables the transmission of high frame rates over just one GigabitEthernet connection, avoiding the complexity and stability issues of Ethernet link aggregation.The algorithm is lossy but no image artefacts are introduced, unlike for example the JPEGcompression. It is therefore very well suited for most machine vision applications except formeasuring tasks where sub-pixel precision is required.

Double rate modulation can be turned off for debugging purposes.

The modulated image is transmitted in mono 8 bit data resolution.

The modulation is run in real-time in the camera’s FPGA. A DLL for the demodulation of theimage for SDK applications is included in the GEV-Player software package that can bedownloaded from Photonfocus (see also 6).

The modulation factor is independent of the image content. The modulated image has thesame number of rows as the unmodulated image. The required image width (number of bytesin a row) for the modulated image can be calculated as follows (value can also be read from acamera property), see also Table 4.21:

wmod = ceil(w/64) + w/2 + 2

6.2.2 GEV Control Windows

This section describes the basic use of the GEV Control windows, e.g. the GEV Device Controlwindow.

The view of the properties in the control window can be changed as described below. At startthe properties are grouped in categories which are expanded and whose title is displayed inbold letters. An overview of the available view controls of the GEV Control windows is shownin Fig. 6.2.

106

To have a quick overview of the available categories, all categories should be collapsed. Thecategories of interest can then be expanded again. If the name of the property is known, thenthe alphabetical view is convenient. If this is the first time that you use a Photonfocus GigEcamera, then the visibility should be left to Beginner.

The description of the currently selected property is shown at the bottom ot the window.

After selecting a property from a drop-down box it is necessary to press <Enter>or to click with the mouse on the control window to apply the property value tothe camera.

A red cross at the upper right corner of the GEV Control Window indicates aparameter error, i.e. a parameter is not correctly set. In this case you shouldcheck all properties. A red exclamation mark (!) at the right side of a parametervalue indicates that this parameters has to be set correctly.

6.2.3 Display Area

The images are displayed in the main window in the display area. A zoom menu is availablewhen right clicking in the display area. Another way to zoom is to press the Ctrl button whileusing the mouse wheel.

6.2.4 White Balance (Colour cameras only)

A white balance utility is available in the PF_GEVPlayer in Tools -> Image Filtering (see Fig.6.3). The gain of the colour channels can be adjusted manually by sliders or an auto whitebalance of the current image can be set by clicking on the White Balance button. To have acorrect white balance setting, the camera should be pointed to a neutral reference (object thatreflects all colours equally), e.g. a special grey reference card while clicking on the WhiteBalance button.

The white balance settings that were made as described in this section, are ap-plied by the PF_GEVPlayer software and are not stored in the camera. To storethe colour gain values in the camera, the Gain settings in the GEV Device Control(in AnalogControl) must be used. If the gain properties in the camera are used,then the PF_GEVPlayer RGB Filtering should be disabled.

6.2.5 Save camera setting to a file

The current camera settings can be saved to a file with the PF_GEVPlayer (File -> Save or SaveAs...). This file can later be applied to camera to restore the saved settings (File -> Open), Note,that the Device Control window must not be open to do this.

The MROI and LUT settings are not saved in the file.

6.5 Calibration of the FPN Correction

The following procedures can be most easily done with the PF_GEVPlayer.

6.5.1 Offset Correction (CalibrateBlack)

The offset correction is based on a black reference image, which is taken at no illumination(e.g. lens aperture completely closed). The black reference image contains the fixed-patternnoise of the sensor, which can be subtracted from the live images in order to minimise thestatic noise.

Procedure to achieve a good correction:

1. Setup the camera width to the mode where it will be usually used. (Exposure time, ROI, ...)Due to the internal structure of the camera, best performance of calibration will beachieved when calibrating under "real conditions".

. If different ROI’s will be used, calibrate image under full ROI.

. If different exposure times will be used, calibrate the camera under the longestexposure time.

2. Set the following properties: Gain (in category AnalogControl) to 1, DigitalOffset (incategory AnalogControl) to 0, DigitalGain (in category DataOutput) to 1 andConvolver_3x3_0_Enable (in category Convolver) to 0. Due to the internal structure of thecamera these settings are required for correct calibration.

3. Wait until the camera has achieved working temperature.

4. Set the property Correction_Mode (in category Correction) to Off. This is not mandatory butrecommended.

5. Close the lens of the camera.

6. Check the value of the property Average_Value (in category PhotonfocusMain). Change theproperty BlackLevel (in category AnalogControl) until Average_Value is between 240 and 400DN. The property Average_Value can be updated by clicking on the propertyAverage_Update(in category PhotonfocusMain).

7. Click on CalibrateBlack (in category Calibration). Wait until the command has beenfinished, i.e.the property Correction_Busy (in category Calibration) is 0. Correction_Busy canbe updated by clicking on the property Correction_BusyUpdate (in category Calibration).

6.5.2 Gain Correction (CalibrateGrey)

The gain correction is based on a gray reference image, which is taken at uniform illuminationto give an image with a mid gray level. Gain correction is not a trivial feature. The quality ofthe gray reference image is crucial for proper gain correction.

The calibration of the gain correction can be skipped if gain correction will notbe used.

Procedure to achieve a good correction:

110

1. The procedure to calibrate the offset correction (see Section 6.5.1) must be run just beforecalibrating the gain correction.

Don’t turn off the camera between the calibration of the offset correction (Cali-brateBlack) and the calibration of the gain correction (CalibrateGrey).

2. Illuminate the camera homogeneously to produce a gray image with an Average_Value (incategory PhotonfocusMain) between 2200 and 3600 DN. Increase or decrease illumination ifAverage_Value is outside this range. The property Average_Value can be updated by clickingon the property Average_Update(in category PhotonfocusMain).

3. Click on CalibrateBlack (in category Calibration). Wait until the command has beenfinished, i.e.the property Correction_Busy (in category Calibration) is 0. Correction_Busy canbe updated by clicking on the property Correction_BusyUpdate (in category Calibration).

6.5.3 Storing the calibration in permanent memory

After running calibration procedures (see Section 6.5.1 and Section 6.5.2) the calibration valuesare stored in RAM. When the camera is turned off, their values are deleted.

To prevent this, the calibration values must be stored in flash memory. This can be done byclicking on the property Correction_SaveToFlash (in category Calibration). Wait until thecommand has been finished, i.e.the property Correction_Busy (in category Calibration) is 0.Correction_Busy can be updated by clicking on the property Correction_BusyUpdate (incategory Calibration).

6.6 Look-Up Table (LUT)

6.6.1 Overview

The LUT is described in detail in Section 4.8. All LUT settings can be set in the GUI(PF_GEVPlayer ). There are LUT setting examples in the PFInstaller, that can be downloadedfrom the Photonfocus webpage.

To manually set custom LUT values in the GUI is practically not feasable as up to4096 values for every LUT must set. This task should be done with the SDK.

If LUT values should be retained in the camera after disconnecting the power,then they must be saved with UserSetSave

6.6.2 Full ROI LUT

This section describe the settings for one LUT that is applied to the full ROI.

1. Set LUT_EnRegionLUT (in category RegionLUT) to False. This is required to use the full ROI LUT.

2. Set LUTEnable (in category LUTControl) to False. This is not mandatory but recommended.

3. Select LUT 0 by setting LUTSelector (in category LUTControl) to 0.

4. Set LUT content as described in Section 6.6.4.

5. Turn on LUT by setting LUTEnable to True.

6.6 Look-Up Table (LUT) 111

6 Software

6.6.3 Region LUT

The Region LUT feature is described in Section 4.8.4. Procedure to set the Region LUT:

1. Set LUT_EnRegionLUT (in category RegionLUT) to False. This is not mandatory butrecommended.

2. Set LUTEnable (in category LUTControl) to False. This is not mandatory but recommended.

3. Select LUT 0 by setting LUTSelector (in category LUTControl) to 0.

4. Set properties LUT_X, LUT_W, LUT_Y and LUT_H (all in category RegionLUT) to desiredvalue.

5. Set LUT content as described in Section 6.6.4.

6. If two Region LUT are required, then select LUT 1 by setting LUTSelector (in categoryLUTControl) to 1 and repeat steps 4 and 5.

7. Turn on LUT by setting LUTEnable to True.

8. Turn on Region LUT by setting LUT_EnRegionLUT (in category RegionLUT) to False.

6.6.4 User defined LUT settings

This section describes how to set user defined LUT values. It is assumed that the LUT wasselected as described in Section 6.6.2 or Section 6.6.3.

For every LUT value the following steps must be done:

1. Set LUTIndex (in category LUTControl) to desired value. The LUTIndex corresponds to thegrey value of the 12 bit input signal of the LUT.

2. Set LUTValue (in category LUTControl) to desired value. The LUTValue corresponds to thegrey value of the 8 bit output signal of the LUT.

The LUTIndex is auto incremented internally after setting a LUTValue. If consec-utive LUTIndex are written, then it is required to set LUTIndex only for the firstvalue. For the next values it is sufficient to set only the LUTValue.

6.6.5 Predefined LUT settings

Some predefined LUT are stored in the camera. To activate a predefined LUT:

1. Select LUT and RegionLUT (if required) as described in Section 6.6.2 and Section 6.6.3.

2. Set LUTAutoMode (in category LUTControl) to the desired value. The available settings aredescribed in property list of the camera which is contained in the PFInstaller.

3. If the LUTAutoMode requires additional settings (e.g. Gamma LUTAutoMode), then it can be setwith LUTAutoValue.

112

6.7 MROI

The MROI feature is described in Section 4.3.4. This section describes how to set the MROIvalues.

When MROI is enabled, then the camera internally processes the MROI entries sequentially,starting at MROI_Index 0. The processing is stopped when either the last MROI_Index is reached orwhen an entry with MROI_Y=1081 is reached.

Procedure to write MROI entries:

1. Disable MROI by setting MROI_Enable to False. This is mandatory otherwise setting theMROI entries will be ignored.

2. Set MROI_Index. In the first run it is set to 0 and then incremented in every run.

3. Set MROI_Y to the starting row of the MROI.

4. Set MROI_H to the height of the MROI.

5. Proceed with step 2, incrementing the MROI_Index. If no more MROI should be set, thenrun the steps 2 to 4 again (incrementing MROI_Index) but set MROI_Y to the value 1081.

6. Enable MROI by setting MROI_Enable to True.

7. Read the property MROI_Htot. Set the property Height (in category ImageFormatControl) tothe value of MROI_Htot. This is mandatory as this value is not automatically updated.

Example pseudo-code to set two MROI: The resulting total height of the example will be 400.

SetFeature(’MROI_Enable’, false);SetFeature(’MROI_Index’, 0);SetFeature(’MROI_Y’, 50);SetFeature(’MROI_H’, 100);SetFeature(’MROI_Index’, 1);SetFeature(’MROI_Y’, 600);SetFeature(’MROI_H’, 300);SetFeature(’MROI_Index’, 2);SetFeature(’MROI_Y’, 1081);SetFeature(’MROI_H’, 1);SetFeature(’MROI_Enable’, true);int heightTot;GetFeature(’MROI_Htot’, &heightTot);SetFeature(’Height’, heightTot);

6.8 Permanent Parameter Storage / Factory Reset

The property UserSetSave (in category UserSetControl) stores the current camera settings in thenon-volatile flash memory. At power-up these values are loaded.

The property UserSetSave (in category UserSetControl) overwrites the current camera settingswith the settings that are stored in the flash memory.

The command CameraHeadFactoryReset (in category PhotonfocusMain) restores the settings of thecamera head

The property CameraHeadStoreDefaults (in category PhotonfocusMain) stores onlythe settings of the camera head in the flash memory. It is recommended to useUserSetSave instead, as all properties are stored.

6.7 MROI 113

6 Software

The calibration values of the FPN calibration are not stored with UserSetSave (orCameraHeadStoreDefaults). Use the command Correction_SaveToFlash for this (seeCorrection_SaveToFlash).

6.9 Persistent IP address

It is possible to set a persistent IP address:

1. Set GevPersistentIPAddress (in category TransportLayerControl) to the desired IP address.

2. Set GevPersistentSubnetMask (in category TransportLayerControl) to the sub net mask.

3. Set GevCurrentIPConfigurationPersistent (in category TransportLayerControl) to True.

4. Set GevCurrentIPConfigurationDHCP (in category TransportLayerControl) to False.

5. The selected persistent IP address will be applied after a reboot of the camera.

6.10 PLC Settings

6.10.1 Introduction

The Programmable Logic Controller (PLC) is a powerful tool to generate triggers and softwareinterrupts. A functional diagram of the PLC tool is shown in Fig. 6.4. THE PLC tool is describedin detail with many examples in the [PLC] manual which is included in the PFInstaller.The simpliest application of the PLC is to connect a PLC input to a PLC output. The connectionof the ISO_IN0 input to the PLC_Q4 camera trigger is given as an example. The resultingconfiguration is shown in Section 6.10.2.

1. Identify the PLC notation of the desired input in Fig. 6.4. In our example, ISO_IN0 maps toA0 or Line0.

2. Select a Signal Routing Block (SRB) that has a connection to the desired PLC input andconnect it to the PLC input. In our example, SRB PLC_I0 will be used as it has a connectionto Line0. To connect the SRB to input, set PLC_I<x> to the input. In the example, set PLC_I0to Line0.

3. Identify the PLC notation of the desired output. A table of the PLC mapping is given inSection 5.6. In the example Q4 is the desired output.

4. Connect the LUT that corresponds to the desired output to the SRB from step 2. In theexample, PLC_Q4 is connected to PLC_I0. ISO_IN0 has an inverter in the I/O decouplingblock, therefore it is better to invert it again in the PLC: set PLC_Q4_Variable0 to PLC_I0_Not.Note that every LUT has the capability to connect up to 4 inputs. In the example only thefirst input (PLC_Q4_Variable0) is used. The other inputs are ignored by setting thePLC_Q4_Variable to Zero and the PLC_Q4_Operator to Or for inputs 1 to 3.

5. If a PLC output is used to connect to a camera trigger, then the corresponding TriggerSource must be activated. In the example, TriggerSource is set to PLC_Q4 and TriggerMode isset to On.

6.11.1 DeviceTemperature

The property DeviceTemperature (in category DeviceControl) shows the value of the temperaturesensor that is selected by the property DeviceTemperatureSelector. It is updated every time theproperty DeviceTemperatureSelector is modified (see also note on drop-down boxes in Section6.2.2).

6.11.2 PixelFormat

The property PixelFormat (in category ImageFormatControl) sets the pixel format. For 10 bits and12 bits there is a selection of plain or packed format. The plain format uses more bandwidththan the packed format, but is easier to process in the software. Table 6.2 shows the number ofbits per pixel to are required for a pixel format. Fig. 6.5 shows the bit alignment of the packedpixel formats.

6.11.3 Colour Fine Gain (Colour cameras only)

To set the colour fine gain:

1. Set the GainSelector (in AnalogControl) to the desired position (see also below).

2. Set the Gain value to the desired value.

The GainSelector can have the following settings:

DigitalAll Overall gain applied to all colour channels

DigitalRed Gain applied to the red channel

DigitalGreen Gain applied to the green channel on the same row as the blue channel

DigitalBlue Gain applied to the blue channel

DigitalGreen2 Gain applied to the green channel on the same row as the red channel

To obtain colour gain values using the PF_GEVPlayer, follow could use the following procedure:

1. Open the camera in the PF_GEVPlayer, apply the desired settings and start the grabbing ofthe camera.

2. Set all colour gains of the camera (DigitalRed, DigitalGreen, DigitalBlue, DigitalGreen2) to1.

3. Point the camera to a neutral reference (object that reflects all colours equally), e.g. aspecial grey reference card.

4. Do a white balancing in the PF_GEVPlayer as described in Section 6.2.4.

5. Copy the values to the camera DigitalGain settings, i.e. copy the value of the Red channelin the Image Filtering window of the PF_GEVPlayer to the DigitalRed value value of thecamera (see above), copy the Green value to both DigitalGreen and DigitalGreen2 andcopy the Blue value to DigitalBlue. These values could also be stored in the camera’snon-volatile storage (see Section 6.8).

6. Disable RGB Filtering in the Image Filtering dialog of the PF_GEVPlayer as the colourchannel correction is now made in the camera.

6.11 Miscellaneous Properties 117

6.12 Width setting in DR1 cameras

To set the width in DR1 cameras, please follow this procedure:

1. Set property Window_W to target width.

2. Read value of property WidthInterface.

3. Set property Width to the value of property WidthInterface.

When double rate is enabled (property DoubleRate_Enable=True), WidthInterface shows thewidth of the modulated image. When double rate is disabled (propertyDoubleRate_Enable=False), WidthInterface has the same value as Window_W.

6.13 Decoding of images in DR1 cameras

The images arrive in a encoded (compressed) format in the DR1 cameras if EnDoubleRate=True.There are functions in the pfDoubleRate package to decode the images. The packagedocumentation is located in the SDK\doc sub-directory of PFRemote installation directory.Examples are located in the SDK\Example\pfDoubleRate sub-directory. The package is installedwith the PFInstaller that can be downloaded from the Photonfocus web page. During theinstallation process, the option DR1 support must be checked.

There are separate decoding functions for monochrome and for colour DR1 cam-eras.

6.13.1 Status line in DR1 cameras

The newer revisions of the DR1 camera series contain the status line feature (see Section 4.11).The status line is supported in the pfDoubleRate.dll from the PFInstaller Rev. 2.38 and later.The whole image, including the status line, can be applied to the demodulation functions. Thestatus line is copied unmodified to the demodulated image, which is the correct behaviour asthe status line is never sent in modulated format.

6.14 DR1Evaluator

The DR1Evaluator is a tool to evaluate the effect of the encoding algorithm that isimplemented in the DR1 cameras. It is included in the PFInstaller that can be downloaded fromthe Photonfocus website.

The main window of the tool is shown in Fig. 6.6.An input file can be selected by clicking on the button Select Input File.

Suitable images for evaluation of the monochrome encoding algorithm can bedownloaded from the website http://www.imagecompression.info/test_images.Download the Gray 8 bit images. The best images for evaluation are the imagesthat were taken by a camera. The artificial images don’t reflect a "real-world"situation.

Only 8 bit monochrome images can be processed by the DR1 Evaluator tool.

118

http://www.imagecompression.info/test_images

Figure 6.6: DR1Evaluator

Only raw colour images, i.e. taken before debayering, can be used as input.

Optionally an output file can be selected by clicking on the button Select Output File. This isthe resulting file after modulation and demodulation of the input image.

Additionally a difference file can be generated by enabling the corresponding checkbox. Thevalue of every pixel is the absolute value of the difference InputFile-OutputFile.

The output images are produced by clicking on the Run button.

7Mechanical and Optical Considerations

7.1 Mechanical Interface

During storage and transport, the camera should be protected against vibration, shock,moisture and dust. The original packaging protects the camera adequately from vibration andshock during storage and transport. Please either retain this packaging for possible later use ordispose of it according to local regulations.

7.1.1 Cameras with GigE Interface

7 Mechanical and Optical Considerations

7.2 Optical Interface

7.2.1 Cleaning the Sensor

The sensor is part of the optical path and should be handled like other optical components:with extreme care.

Dust can obscure pixels, producing dark patches in the images captured. Dust is most visiblewhen the illumination is collimated. Dark patches caused by dust or dirt shift position as theangle of illumination changes. Dust is normally not visible when the sensor is positioned at theexit port of an integrating sphere, where the illumination is diffuse.

1. The camera should only be cleaned in ESD-safe areas by ESD-trained personnel using wriststraps. Ideally, the sensor should be cleaned in a clean environment. Otherwise, in dustyenvironments, the sensor will immediately become dirty again after cleaning.

2. Use a high quality, low pressure air duster (e.g. Electrolube EAD400D, pure compressedinert gas, www.electrolube.com) to blow off loose particles. This step alone is usuallysufficient to clean the sensor of the most common contaminants.

Workshop air supply is not appropriate and may cause permanent damage tothe sensor.

3. If further cleaning is required, use a suitable lens wiper or Q-Tip moistened with anappropriate cleaning fluid to wipe the sensor surface as described below. Examples ofsuitable lens cleaning materials are given in Table 7.1. Cleaning materials must beESD-safe, lint-free and free from particles that may scratch the sensor surface.

Do not use ordinary cotton buds. These do not fulfil the above requirements andpermanent damage to the sensor may result.

4. Wipe the sensor carefully and slowly. First remove coarse particles and dirt from thesensor using Q-Tips soaked in 2-propanol, applying as little pressure as possible. Using amethod similar to that used for cleaning optical surfaces, clean the sensor by starting atany corner of the sensor and working towards the opposite corner. Finally, repeat theprocedure with methanol to remove streaks. It is imperative that no pressure be appliedto the surface of the sensor or to the black globe-top material (if present) surrounding theoptically active surface during the cleaning process.
