Abstract:
A stereographic image compressor comprising:a function processing unit, responsive to a first image signal containing image information of a scene from a first field of view, and a second image signal containing image information of said scene from a second field of view, for generating a difference image signal, indicative of differences between said first image signal and said second image signal; anda lossy compressor, responsive to said difference image signal, for compressing image information contained in said signal, to generate a compressed image information signal; whereinsaid function processing unit comprises means for generating said difference image signal by scaling said first image signal with a first constant to generate a scaled first image signal, scaling said second image signal with a second constant to generate a scaled second image signal, and subtracting image information contained in said scaled first image signal from image information contained in said scaled second image signal.
