Abstract

A graphics system and method for panning from one portion of a stored image to another portion of the image includes a frame buffer, one or more display devices, one or more raster parameter registers, and one or more raster parameter updaters. The image is stored in the frame buffer and each display device is configured to display less than the entire image. A panning operation is initiated by requesting an update of one or more of the raster parameter registers during a next blanking period.
