When an image is displayed on a display screen having a larger display area than a displayed image, a size of the displayed image is minutely changed cyclically in order to avoid boundary lines to be recognized when a full size image is displayed on the display screen of the display device. Direction of the size change of the displayed image is in the vertical direction or the horizontal direction. In this case additional non-image signal is added to top, bottom, left and/or right of the displayed image.
