You can now enjoy 3D movies on TV without those vexing 3D glasses, thanks to a new technology being developed in Germany.
The 3D movies currently available on Blu-ray are based on two different perspectives two images, one for each eye.
autostereoscopic displays need five to 10 views of the same scene
(depending on the type). In the future, the number will probably be even
This is because these displays have to present a 3D image

at the Fraunhofer Institute for Telecommunications at Heinrich-Hertz
Institute (HHI) in Berlin have developed a technology that converts a
Blu-ray's existing 3D content in a manner that enables them to be shown
on autostereoscopic displays.
"We take the existing two images and
generate a depth map a map that assigns a specific distance from the
camera to each object," says Christian Riechert, research fellow at HHI.
systems were only capable of generating such depth maps at a
dramatically slower pace; sometimes they even required manual

Researchers have already finished the software that
converts these data. In the next step, the scientists, working in
collaboration with industry partners, intend to port it onto a hardware
product so that it can be integrated into TV.
Nevertheless, it will still take at least another calendar year before the technology hits store shelves.
Researchers will unveil this technology in Berlin at this year's IFA trade show from Aug 31 to Sep 5.
