Abstract
The object is to increase the efficiency of processing by conferring the residual image function on hardware and to provide an image processing device wherein processing is implemented at higher speed. In an image processing device equipped with an image memory and a control section that writes generated image data to the image memory, there is provided a blend circuit that reads image memory or image data from image memory and attenuates the read image data and that writes this together with newly generated image data into another image memory, thereby producing a residual image effect.
