Apple has patented 3D projection method
Apple has patented 3D projection method
Apple is a projection method for three-dimensional images has registered. The viewer must wear no glasses to see the 3D effect.
The U.S. Patent No. 7,843,449 describes how the pixels of the image on a reflective, textured surface can be projected. There, they radiate so that the left and the right eye of the beholder receive different signals, which produces the stereoscopic effect. The system also determines the location of the viewer, so that multiple people can view from different angles, the 3D projection.
The aim of the technology are now, according to the published patent description "affordable, on its own three-dimensional displays that give the viewer complete freedom of movement". It does away with different colored glasses, making it not necessary that the audience remain seated at a defined point.
Interestingly, one of the patent application for the drawbacks of existing 3D display techniques, including Parallel view and Holograms. Probably uses the same view Nintendo's next portable console 3DS. Because of the angle difference between the two eyes are each given pixel hidden, so, again, no glasses are necessary.
A hologram-like technology and share the other hand, 3D TV as the Toshiba one. To generate a two-dimensional image in real time, nine angle corrected versions that combine through the television projection to a 3D view. The spectators must remain in his seat but, like Apple criticized. Moreover, the method is extremely computationally expensive.
As with many new patents can also be derived from this is not soon appearing product. The request also comes from the year 2006.
