<P>PROBLEM TO BE SOLVED: To provide a display controller increasing display process speed for a display device and when used for controlling a display operation part such as a copier, largely improving operability and responsiveness of the display operation part. <P>SOLUTION: By an overlap controlling means 9a, overlapping of image information of a plurality of windows per data access is sequentially implemented, and the image information of the overlapped windows is sequentially stored into an outside image information storing means 10a by a DMA. Thus, this device can cope with simultaneous display of many windows, display process speed for a display device can be increased, and when used for controlling a display operation part such as a copier, operability and responsiveness of the display operation part can be largely improved. <P>COPYRIGHT: (C)2004,JPO |
