Title: Motion vector detecting apparatus

Abstract: A motion vector detecting apparatus generates motion vectors in units of subblocks (submacroblocks) and motion vectors in units of macroblocks on the basis of absolute difference of the individual pixels calculated by absolute difference calculating circuits. A switching arrangement switches the absolute difference calculating circuits to generate one of these two kinds of vectors. For generation of the motion vectors in units of subblocks, a motion vector search range can be shifted by adding an offset in accordance with, e.g., the motion of an image.
