Abstract
A motion vector detecting apparatus using the minimum residual difference between corresponding picture elements from two consecutive frames and an interpolation circuit to develop a moving vector with half-picture-element pitch accuracy. A residual difference is obtained by comparing each frame of an image signal fed into the apparatus with each previous frame. A solution vector is obtained by taking the minimum value of the absolute values of the residual differences. The solution vector is adjusted by a correction value, which is determined by interpolating extreme values in the vicinity of this solution vector and taking a minimum therefrom, to obtain the half-picture-element pitch solution vector.
