Abstract:
A stereographic image compressor comprising:a pair of image sensors for providing a first image signal and a second image signal, said first image signal indicative of a first field of view of an image, said second image signal indicative of a second field of view of said image;an image size and position unit, responsive to said first image signal and said second image signal, for resizing and repositioning said images represented by said first and said second image signals, in accordance with an image position signal and an image size signal, to generate a modified first image signal and a modified second image signal, said modified first image signal and said modified second image signal each characterized by a same size and position;a function processing unit, responsive to said modified first image signal and said modified second image signal, for generating, in accordance with at least a first weighting signal, a difference image signal, indicative of differences between said modified first image signal and said modified second image signal;a lossy compressor, responsive to said difference image signal, for compressing image information contained in said difference image signal, to generate a compressed image information signal; andan adaptive processing unit, responsive to a calibration mode, for adaptively generating said image position signal, said image size signal and said first weighting signal as a function of said difference image signal and said compressed image information signal.
