Abstract:
1. A motion vector detection apparatus that obtains, for each of a plurality of blocks of a predetermined size into which one frame is divided, motion vector information in units of a plurality of partitions of differing rectangular shapes and differing sizes, up to the size of the blocks, comprising: a partition connector that, when motion vectors for a plurality of partitions are obtained for one of the blocks, decides whether or not to connect a plurality of the partitions for which the motion vectors are obtained, and if the partitions are connected, includes motion vector information about the resulting connected partition in motion vector information output from the motion vector detection apparatus, wherein the motion vector detection apparatus can select a reference image to use from among reference images of a plurality of frames, and wherein the partition connector connects partitions conditional on the reference images having identical time stamps and differences between directions and magnitudes of the motion vectors being within a predetermined tolerance range.
