ABSTRACT:
In a moving picture encoder, a motion-vector detection circuit detects each motion vector between frame pictures of moving picture data, and compression encoding units perform compression encoding on the moving picture data in units of predetermined pictures having differently arbitrary shapes by performing motion-compensation interframe prediction using the detected motion vector in common. This can greatly reduce the processing load of the entire compression encoding on a plurality of pictures obtained from a single piece of the moving picture data since the motion-vector detection circuit, on which a large processing load acts, is formed as a single unit. This structure can accelerate the compression encoding on the pictures obtained from the single piece of the moving picture data.
