ABSTRACT:
A portable image viewer including a compact housing with a cover for protecting a top surface thereof. Also included is a liquid crystal display situated on the top surface of the housing for displaying purposes. A standard floppy disk drive has a receiving aperture for accepting a non-volatile floppy disk and extracting data therefrom. An input port is included for accepting data from a conventional computer. Finally, hardware based control circuitry is situated within the housing and connected to the display and floppy disk drive. The control circuitry, in a first mode, is adapted to retrieve a specific file from the floppy disk and automatically fit the image from the file on the display. In a second mode of operation, the control circuitry is adapted to accept a file via the input port and utilize similar imaging fitting techniques. In both the first mode and second mode of operation, after the image is displayed, the control circuitry is adapted to enlarge the image and pan in multiple directions thereon for viewing more closely different portions thereof.
