REAL-TIME VIDEO SIGNAL INTERWEAVING FOR AUTOSTEREOSCOPIC DISPLAY
First Claim
1. A Method for real-time generation of a display video signal, adapted to be fed to an autostereoscopic display device for displaying an autostereoscopic video image of a changing three-dimensional scene, the display device including a matrix of active light-emitting or light-modulating elements, arranged in rows, and the display video signal structured as a sequence of frames, each frame structured as a sequence of lines that correspond to consecutive rows of said elements, the method comprising:
- (d) Simultaneously obtaining a plurality of projection video signals, each signal structured as a sequence of frames representing two-dimensional projection images of the scene in a respective different direction and each frame including a plurality of pixels, each pixel carried as one or more digital values;
(e) copying pixel values from said projection video signals, or from any processed version thereof, into a digital representation of one or more of said rows so that values from different projection video signals become mutually interwoven.(f) reading out said copied values from said digital representation in a line-by-line sequence and formatting them into the display video signal.

14. Apparatus for real-time conversion of a plurality of projection video signals, representative of a changeable three-dimensional scene as projected in respective different directions, into a display video signal, adapted to be fed to an autostereoscopic display device for displaying an autostereoscopic image of the scene, each of the projection video signals being structured as a sequence of frames representing corresponding sequential two-dimensional projection images of the scene, the display device including a matrix of active light-emitting or light-modulating elements, arranged in rows, and the display video signal structured as a sequence of frames, each frame structured as a sequence of lines that correspond to consecutive rows of said elements, the apparatus comprising:
-
a plurality of Conditioning Processors, each receptive to a respective projection video signal and operative to output digital values of sequential pixels representative of corresponding projection images; a Combiner, including a buffer storage that is adapted to store image values for one or more of said rows, the Combiner being operative to copy values obtained from said Conditioning Processors into said buffer storage so that values from different Conditioning Processors become mutually interwoven; and a Video Formatter, operative to read out said copied values from said buffer storage in a line-by-line sequence and to format them into the display video signal. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
