A new technology has been developed that will make it possible for viewers to enjoy three-dimensional programmes without those bothersome 3D glasses.
Though prototypes of these TV screens already exist, consumers will not have to wait much longer for the market introduction of these autostereoscopic displays.
Nevertheless, the content might be a bit problematic - the 3D movies currently available on Blu-ray are based on two different perspectives, i.e. two images, one for each eye.
However, autostereoscopic displays need five to ten views of the same scene (depending on the type). 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 – indeed, 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
Researchers at Fraunhofer Institute for Telecommunications, Heinrich-Hertz Institute, HHI in Berlin recently 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 – that is to say, a map that assigns a specific distance from the camera to each object,” Christian Riechert, research fellow at HHI said.
“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.
