Abstract
A motion vector detection section detects as a reference macroblock a reference pixel block with which a sum of differences in pixel data between a target macroblock and each pixel is equal to or smaller than a predetermined threshold among macroblocks in a reference frame. An intraframe time management section measures a detection time. If an allocated predetermined detection time has elapsed before detection of such a reference macroblock, the detection processing is stopped. In this case, a macroblock with which the previously-calculated sum is minimum is selected as a reference macroblock.
