Abstract
A video display system, which enables users to navigate (by panning and zooming) throughout very large digital images. The digital images are stored on a disk drive in a proprietary file format (which is optimized for speed) and then viewed via a VGA connection. The system enables a user's ability to navigate throughout the entire image seamlessly. Instead of requiring a large amount of memory to display these images, the images are essentially transferred directly from the disk drive to video memory.
