A motion vector search apparatus has two internal memories for storing one macroblock of current image data each and N internal memories for storing M macroblocks of reference image data each, where M and N are integers greater than one. Selectors feed data from one of the current image memories and N−1 of the reference image memories to a processor that carries out a block matching calculation, on the basis of which a detector finds a motion vector for the selected macroblock of current image data. During the search, data for one new current image macroblock and M new reference image macroblocks are read into the non-selected memories, so that as soon as the motion vector is found, the search for the next motion vector can begin.
