Method of and apparatus for recording motion picture, which generate encoded data with higher compression efficiency using a motion vector similarity
A motion picture recording apparatus that includes a similar-motion-area setup unit which sets up blocks having a similar motion vector as a similar motion area, the similar motion vector being included in motion vectors calculated by a block-based motion search unit. The recording apparatus also includes a representative-motion-vector calculation unit which calculates a representative motion vector by use of a motion vector provided by each block included in the similar motion area. The recording apparatus further includes a selection unit which selects either the representative motion vector or the motion vector provided by each block, which is to be used for each block in the similar motion area. The recording apparatus also includes an encoder which performs coding processing using the selected motion vector and a prediction picture, for each block in the similar motion area.
