  • Video format unit
    Patent number: 4467354
    Abstract: In high speed imaging systems wherein document images are lifted and stored, it is desirable to reduce the amount of information to be stored. A video format unit utilizing video information from a data lift enhances the video information and then compresses the enhanced video data by coding the data in a repetitive run length type code. The coded data is then stored in an on-line system to permit the immediate recall of stored images.
