INTRODUCTIONINTRODUCTION
Three dimensional TV is expected to be next revolution in the TV history.
They implemented a 3D TV prototype system with real-time acquisition, transmission and 3D display of dynamic scenes.
This is the first real-time end-to-end 3D TV system with enough views and resolution to provide a truly immersive 3D experience.

BASICS OF 3D TVBASICS OF 3D TV
Binocular parallax-Binocular parallax defers to the ability of the eyes to see a solid object and a continuous surface behind that object even though the eyes see two different views.
Motion parallax-It means information at the retina caused by relative movement of objects as the observer moves to the side (or his head moves sideways).

CONTD…CONTD…Depth perception-It allows the
beholder to accurately gauge the distance to an object. It is the visual ability to perceive the world in three dimensions.
Stereographic images- It means two pictures taken with a spatial or time separation that are then arranged to be viewed
simultaneously.

Stereoscope-It is an optical device for creating stereoscopic (or three dimensional) effects from flat (two-dimensional) images; D.Brewster first constructed the stereoscope in 1844.
Holographic Images-A luminous, 3D, transparent, colored and nonmaterial image appearing out of a 2D medium, called a hologram. A holographic image cannot be viewed without the proper lighting.

MODEL BASED SYSTEMMODEL BASED SYSTEM
One approach to 3D TV is to
acquire multiview video from
sparsely arranged cameras
and to use some model of the
scene for view interpolation.

LIGHT FIELD SYSTEMLIGHT FIELD SYSTEM
A light field represents radiance as a function of position
and direction in regions of space free of occludes.
The light field describes the amount of light traveling
through every point in 3D space in every possible
direction.

CONCLUSIONCONCLUSION
Most of the key ideas for 3D TV systems presented in this
paper have been known for decade, such as lenticular
screens, multi projector 3D displays, and camera array for
acquisition. This system is the first to provide enough view
points and enough pixels per view points to produce an
immersive and convincing 3D experience. Another area of
future research is precise color reproduction of natural scenes
on multiview display.
