INTRODUCTION 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 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… 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. 6

CONTD… Stereoscope-It

is an optical device for creating stereoscopic (or three dimensional) effects from flat (twodimensional) 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.

OVERVIEW OF THE SYSTEM Distributed architecture Scalability Multiview video rendering High-resolution 3D display Computational alignment for 3D display

MODEL 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 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.

CONCLUSION 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.
