  • High resolution display of large electronically stored or communicated images with real time roaming
    Patent number: 7840908
    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.
    Type: Grant
