Abstract: A document processing system directs documents at a high rate of speed past an optical scanner which captures written information on the documents as video image data. The video image data is directed over a data channel to a host computer system where the data is stored on a mass data storage device for subsequent retrieval. A buffer is provided between the scanner and the data channel, which receives data a rate which varies in relation to the amount of information present on the documents. Data is extracted from the buffer at a rate which is limited by the host computer's channel transfer rate. A control means is associated with the buffer and is operable for controlling a hierarchy of actions ranging from slowing down the incoming data stream to stopping the data stream altogether in order to prevent any loss of video image data due to overfilling of the buffer.

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.

Abstract: A method and apparatus are disclosed for reading a two-dimensional bar code having bars located nominally at predetermined pitch increments. The invention provides a method and apparatus for reading a two-dimensional bar code and dynamically segmenting it into individual bars on a real time basis, as it is read. The segmentation is done on a bar-to-bar basis, and may be adjusted for an individual bar as necessary. The method and apparatus locate the bar data, scan it, and create a profile vector having elements based upon the amount of image data in each scan. The vector is compared to a predetermined stored set of vector elements representing the likelihood that each scan line of image data contains bar image data. Those scan lines of image data corresponding to a bar image are sent to recognition logic and those scan lines of image data corresponding to a space are disregarded.
