ABSTRACT:
Movement vector detection device comprises a concentration difference operation circuit to compute a concentration difference between image planes, space gradient operation circuit to compute an average space gradient of a current image plane and a preceding image plane, concentration difference correction circuit to correct by the sign of space gradient the concentration difference obtained by concentration difference operation circuit, first totalizing circuit to computes the total sum in a prescribed block of the outputs from the concentration difference correction circuit, second totalizing circuit to compute the total sum in a prescribed block of the absolute value of average space gradient by the space gradient operation circuit and division circuit to divide the outputs from the first totalizing circuit by outputs from the second totalizing circuit.
