The multiple hierarchical search sections which search

摘要

PROBLEM TO BE SOLVED: To provide a motion vector detection apparatus and a motion vector detection method, for detecting a motion vector at high speed.;SOLUTION: The motion vector detection apparatus is provided with: a plurality of hierarchy search parts for searching for a motion vector in a target hierarchy; and an operation part for operating a sum of motion vectors in respective hierarchies searched for by the plurality of hierarchy search parts as a motion vector to obtain. In one or more hierarchy search part having all the plurality of hierarchy search parts or hierarchies other than the lowest hierarchy as a target, a frame image is binarized with a threshold which is set higher the greater a block size is with respect to the degree of pattern complication in the search block as a reference by having a search block larger than a lower hierarchy as a unit and a motion vector in the target hierarchy is searched for with the binarized search block as a unit.;COPYRIGHT: (C)2010,JPO&INPIT
