<p><P>PROBLEM TO BE SOLVED: To shorten a period of time required for detection of a motion vector. <P>SOLUTION: With a method for detecting a motion vector between an input image and a reference image used for a reference of the input image, first, a two-dimensional search region having a predetermined pattern is determined in the reference image (S10), and matching is computed between a coding target block in the input image and multiple blocks represented by multiple search points included in the search region in parallel (S12). In a case wherein the evaluated computation results exhibit optimum matching results (Y in S14), the motion vector is determined based upon the computation results (S16). In a case wherein the optimum solution has not been obtained (N in S14), the search region for the next matching is determined based upon the evaluation results (S18), and search is repeated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
