ABSTRACT:
Video-inputting portion 3, video-outputting portion 8, motion-estimating portion 4, pixel-level-arithmetic portion 5, variable-length-encoding portion 6, and code-outputting portion 7 are coupled with frame memory 10 through buffer and frame memory controlling portion 9 and controlling processor 1 through host interface portion 2. Frame memory 10 is accessed by video-inputting portion 3, video-outputting portion 8, motion-estimating portion 4, pixel-level-arithmetic portion 5, variable-length-encoding portion 6, and code-outputting portion 7 in time sharing manner. Controlling of video-inputting portion 3, video-outputting portion 8, motion-estimating portion 4, pixel-level-arithmetic portion 5, variable-length-encoding portion 6, and code-outputting portion 7 is centralized in controlling processor 1. Portions in dotted frame 20 are integrated in one LSI chip.
