Claims
- 1. A video-coding device for encoding predicted error information determined as a difference between an input video-frame and a predicted video-frame obtained by executing motion-compensated interframe prediction, wherein a motion-compensated interframe predicting portion is provided with a variable-area predicted-frame generating portion for dividing a processable area of the input video-frame into suitable areas according to motion vectors and a reference video-frame and generating a predicated video-frame by using a motion vector per pixel determined from the inputted motion vectors and an area dividing pattern deciding portion for controlling dividing of a processable area and outputting a predicted video-frame and side-information such as motion vectors and area-dividing information.
