Abstract: A method of image motion distortion correction involving the steps of electronically scanning an optical image to produce first and second lines of stored digital pixel data indicative of the intensity of picture elements of the optical image, registering within a corresponding scanning window position the difference between each second line picture element value of a number of sets of second line picture elements, and a number of first individual line picture elements, each corresponding to an associated set, thereafter utilizing that particular window position having the minimum accumulated difference value to produce an image shift signal having a value corresponding to that particular window position, shifting the storage position of the second line with respect to the first line by an amount proportional to the value of the shift signal, and utilizing the shifted lines of data to modulate an image producing readout device such as a CRT to reproduce the optical image.
