An image processor in which an input image signal having a number L.sub.1 of gradation levels is converted into an image signal having a number L.sub.2 (<L.sub.1) of gradation levels, and the converted image signal is stored. The stored image signal is used to restore the original image signal, and motion of an image is detected on the basis of an image signal input in the current period and the restored image signal in the previous period.
