Abstract For block motion estimation the current frames are divided into blocks and the picture elements of each block are compared with the picture elements within a search area of a reference frame in order to determine a motion vector. According to the invention the processing requirements are reduced by parallel processing, wherein the search area is separated into search area stripes. The picture elements of k neighboring blocks are compared with the picture elements of the search area stripes until the complete search area for a block has been processed. A block, for which the complete search area has been processed, is substituted by an unprocessed block. In an advantageous manner, the lines of the current frame are separated into block sections comprising k neighboring blocks.
