<p><P>PROBLEM TO BE SOLVED: To efficiently execute motion compensation processing while reducing computational complexity for motion compensation. <P>SOLUTION: The motion compensator comprises: a detection means for detecting a first deviation amount between a first frame and a second frame to minimize a differential between pixels constituting the first frame and pixels constituting the second frame; a calculation means for calculating a second deviation amount between an input frame and each of frames of a plurality of reference frame candidates based on the first deviation amount regarding each of the frames among the plurality of reference frame candidates; a selection means for selecting, as a reference frame, a reference frame candidate with the minimum second deviation amount; and a motion vector calculation means for calculating a motion vector based on each of macro blocks constituting the reference frame regarding each of the macro blocks constituting the input frame. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
