ABSTRACT:
In an image processing system of this invention, bit information indicating whether or not a dynamic image is to be overlay-displayed is stored in a memory in correspondence with display pixel positions, and an output image memory control unit reads out this bit information in synchronism with a screen display operation. An overlay processing unit alternatively selects specific input dynamic image signals to be window-displayed in units of display regions, and an image signal of an output image memory, which signal is displayed on another region on the basis of the bit information.
