ABSTRACT:
An image control device for use in the computer system. The computer system includes a microprocessor, a bus coupled to the microprocessor, a video memory coupled to the bus and a display device. Writing of an image system signal into the video memory is controlled by supplying a first write address to the video memory. Reading of an image signal out of the video memory is controlled by supplying a read address to the video memory. The operation of reading the image signal out of the video memory independently changes a display part and a magnification of an image represented by the image signal read out of the video memory so that the display part of the image is displayed by the magnification on the display device.
