ABSTRACT:
A method of detecting motion vectors detects motion based upon calculation of picture data of a reference block and upon picture data in a search block, the search block located within a search area and then variably sets the search area. An apparatus for detecting motion vectors includes a motion detection circuit for detection motion based upon calculation of picture data of a reference block and upon picture data in a search block, the search block located within a search area and a circuit for variably setting the search area.
