An apparatus is provided to reduce the memory capacity required to hold the data of a search area when motion vector detection is conducted in a wider area by using a plurality of motion vector detecting circuits. A motion vector detecting device includes an object pixel memory, reference pixel memory, motion vector detecting circuits, and a vector selecting circuit. Data of different blocks are provided to each of motion vector detecting circuits from the object pixel memory. Data of common search areas are simultaneously provided to the motion vector detecting circuits from the reference pixel memory. Output from each of the motion vector detecting circuits is processed by the vector selecting circuit to provide a motion vector in a search area which is wider than the search area of each motion vector.
