摘要:
A camera is in communication with a microcomputer, having a memory. A plurality of communication controllers are in communication with the microcomputer, and each communication controller is in control of up to two monitors. Pictorial data from the camera is compressed and stored in the microcomputer memory. To display the pictorial data on a monitor, the monitor queries its associated communication controller which in turn queries the microcomputer. The microcomputer determines the location of the coded data associated with the pictorial document in the memory and decodes the coded data. The decompressed data is provided to the requesting monitor whereby to display the pictorial data on the screen of the requesting monitor.
