ABSTRACT:
A motion vector detection device in which the absolute value of the difference between a plurality of sets of representative points, selected at the same interval as the search area consisting of Q.times.R pixels, and pixel data of the current field at the positions of the q.times.r pixel interval is calculated to find vectors, data of each vector are cumulatively summed to find the remainder, data of the remainder of each vector are compared to one another to find a motion vector and a motion vector is found at an interval less than q.times.r by interpolation from the motion vector and values of the remainder in its vicinity.
