Abstract
A display system including a programmable video graphic controller allows for continuous smooth panning through memory which is larger than the system's video memory. The video memory is continuously updated with new image data so as to form two duplicate images within video memory. When an edge of video memory is reached, the displayed image may be shifted from one of the duplicate images to the other within video memory to allow continuous panning without the need to stop and refresh the image data every time an edge of video memory is reached.
