Video Processing

A video processing apparatus comprises a first camera (I) for producing a first image signal ( 9 ), and a second camera ( 3 ) for producing a second image signal ( 11 ). The first image signal ( 9 ) and the second image signal ( 11 ) are offset versions of the same scene, for example relating to "right" and "left" versions of the scene as viewed through the first and second cameras, respectively. A depth estimator ( 5 ) receives the first and second image signals ( 9, 11 ), and produces a depth signal ( 13 ) for a region in the scene. A data compressor ( 7 ) receives an image signal from one of the cameras, for example the first camera ( 1 ), and compresses the video data in the image signal to produce a compressed image signal ( 14 ). The data compression for a particular region is performed based on the depth signal ( 13 ) received from the depth estimator ( 5 ) for that region. The apparatus can be configured to compress image data for objects in the foreground with a higher resolution than objects located in the background.
