Abstract
A system and method for dynamically resizing graphic images of variable image complexity to generate display images at a constant frame rate for output to a display device. In one frame, an image resolution is determined and a graphic image is drawn to the determined image resolution. In the subsequent frame, the graphic image is magnified to a target resolution prior to being output to a display device. The synchronization of the drawing of the graphic image and its display is managed by a swap buffer signal. The present invention further provides for the double buffering of graphic images and their corresponding image resolutions. The present invention further provides for the independent dynamic resizing of multiple channels, such that, a plurality of display devices can independently resize graphic images of variable complexity at a constant frame rate.
