No More 3D glass for 3D Movies

3D Glass

A new technology have developed to enjoy 3D movie experience at home without using the 3-D glasses. This technology simply adapts conventional 3-D films to the new displays in real time will be unveiled in Berlin at this year's IFA trade show next month.

Now researchers at Fraunhofer Institute, Heinrich-Hertz Institute, HHI in Berlin developed a technology that converts a Blu-ray's existing 3-D content to be shown on autostereoscopic displays.

"Lounging on a sofa while watching a 3D movie is an exquisite pleasure for many film fans. Be that as it may, those nettlesome 3D glasses might diminish the fun somewhat," researchers said in a statement.
Though prototypes of these TV screens already exist, consumers will not have to wait much longer for the market introduction of these autostereoscopic displays.

However, autostereoscopic displays need five to ten views of the same scene. In the future, the number will probably be even more. This is because these displays have to present a three-dimensional image in such a manner that it can be seen from different angles, there is more than one place to sit on a sofa, and you should be able to get the same three dimensional impressions from any position.

"We take the existing two images and generate a depth map -- that is to say, a map that assigns a specific distance from the camera to each object," said Christian Riechert, research fellow at HHI.

"From there we compute any of several intermediate views by applying depth image-based rendering techniques. And here's the really neat thing: The process operates on a fully automated basis, and in real time," he said. Previous systems were only capable of generating such depth maps at a dramatically slower pace; sometimes they even required manual adaption. The researchers have already finished the software that converts these data.
