ABSTRACT:
The control circuit controls output of template block data held in the input section such that a plurality of operation units within the operation section are provided with data of unadjacent template blocks that are different from each other. The operation units within the operation section detect motion vectors according to the template block data provided thereto. Thus, motion vector detection in the template blocks except for those in a region on a display screen requiring no motion vector detection is distributed in the plurality of operation units. Accordingly, the motion vector search can be performed in a wider range in a vertical or horizontal direction than in the conventional case within the same operation time.
