Abstract
The invention provides an improved image memory device including an image processing memory unit incorporated into a universal image processing device and an address switching control circuit connected thereto, wherein an address data for raster display and an address data fed from an external input-output device are periodically selected by an address switching control circuit for supply to the image processing memory unit so that the memory unit may be accessed by an external input-output device without intercepting the raster display with remarkably reduced data transfer time.
