Abstract
A graphic display control apparatus which automatically scrolls display contents of a screen vertically, horizontally or diagonally by automatically updating the reading address corresponding to the amount of scrolling, when read-out areas for display information of one screen read out from a frame memory whose capacity allows a CPU to write display information larger than one screen, e.g., an animation background, a motorcar navigation map or the like therein are sequentially moved, thereby to lighten the burden of the CPU at the scrolling time.
