Abstract
An apparatus detects a motion vector using image data to be encoded, and a plurality of reference image data. The apparatus conducts a motion vector search for first reference image data using a large block obtained by dividing the image data to be encoded, and divides the large block into a smaller block size at the position of a smallest matching error. The apparatus determines a block size used in a motion vector search for another reference data based on matching errors in the small blocks.
