2. Aims on 3D TV Japan a project aim to 3d tv
To provide 3D picture with smell and touch
Virtual reality
Contribution of university research institute and companies (universal communication.)

3. 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.

Computational alignment for 3D display

12. 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

13. Light Field System A light field represents radiance
as a function of position and
direction in regions of space
free of occluders.
The light field describes the
amount of light traveling through
every point in 3D space in every
possible direction.

15. Architecture of 3D TV

16. Acquisition The acquisition stage consist of an array of
the hardware synchronized cameras
• CCD image Sensors
• MPEG-2 Encoding
• PCI card

17. Transmission Gigabit Ethernet
A transmission technology, enables super net to deliver enhanced network performance.

18. Decoder & Consumer Processing
The receiver side is responsible for generating the appropriate images to be displayed.

28. 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.
