<P>PROBLEM TO BE SOLVED: To shorten a processing time to be spent on a motion vector generation. <P>SOLUTION: First and second MV calculation sections 406a and 406b generate MVs of object blocks based on MVs of reference blocks, respectively. An analysis section 401 analyzes a macroblock type and a sub-macroblock type, and outputs an analysis result thereof. A distribution control section 402 determines a reference direction of each of partitions into which a basic macroblock is divided based on the analysis result of the analysis section 401, and when partitions referring to one frame are consecutive, a plurality of the consecutive partitions are distributed in the first MV calculation section 406a and the second MV calculation section 406b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
