SMALL PPT ON 3D TECHNOLOGY AND STANDARD

1. WHAT IS 3D TECHNOLGY
AND
3D TV?????

2. • 3D television (3DTV) is television that
conveys depth perception to the viewer
by employing techniques such
as stereoscopic display, multi-
view display, 2D-plus-depth, or any other
form of 3D display.
• Most modern 3D television sets use
an active shutter 3D system or
a polarized 3D system, and some
are autostereoscopic without the need of
glasses.

3. Displaying technologies
• Anaglyph 3D – with passive color filters
• Polarized 3D system – with passive
polarization filters
• Active shutter 3D system – with active
shutters

4. Functional principle of active shutter
3D systems.

5. Functional principle of polarized 3D
systems.

6. Producing technologies
• Stereoscopy is the most widely accepted
method for capturing and delivering 3D video.
• It involves capturing stereo pairs in a two-view
setup, with cameras mounted side by side and
separated by the same distance as is between
a person's pupils

7. BROADCASTING

8. Health effects
• Some viewers have complained
of headaches, seizures and eyestrain after
watching 3D films.
• There have been several warnings, especially
for the elderly
• It is believed that approximately 12% of
people are unable to properly see 3D images,
owing to a variety of medical conditions
