3D television conveys depth perception to viewers through techniques like stereoscopic display, multi-view display, or 2D-plus-depth display. Most modern 3D TVs use active shutter 3D systems or polarized 3D systems, and some use autostereoscopic displays that don't require glasses. 3D is produced through technologies like stereoscopy, which involves capturing stereo pairs with two cameras mounted side by side to mimic human binocular vision. However, some viewers have reported health issues like headaches or eyestrain from watching 3D content.

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

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
