Abstract

In a motion vector detection apparatus which processes a plurality of candidate blocks of pixels defined in a search range within a reference frame, to detect a candidate block having maximum correlation with an object block of M.times.N pixels in an object frame, a first input circuit receives successive pixels of the object block in respective clock periods and transfers each pixel to a specific one of a set of M.times.N processor circuits, while a second input circuit receives successive pixels of the search range and transfers each to a specific one of the processor circuits, such that the pixel values of a candidate block are respectively sequentially processed by each of the processor circuits in successive clock periods, with difference values between corresponding object and candidate block pixel values, generated by respective processor circuits, being cumulatively added to obtain an inter-block error value for that candidate block.
