ABSTRACT:
Documents, such as bank checks, are processed at a high rate of speed on an image processing system which optically scans the documents and converts optically perceptible data on the documents into video image data. The video image data from the scanner is compressed by data compression techniques and the compressed data is sent over a high speed data channel to a high speed mass storage device which receives and temporarily stores the data. A lower speed mass data storage device, such as an optical disk, is connected for receiving at a lower data transfer rate the compressed video image data and for storing the video image data for subsequent retrieval. The system also includes real-time quality control systems for monitoring the quality of the image data to detect the existence of unacceptable image quality data and for generating a signal which can be used for immediately stopping the generation of unacceptable quality image data.
