A common scanning unit is utilized in an optical character reader which reads both alphanumeric and bar code characters. An N column by M row area photosensor detects both the alphanumeric and bar code signals. The system detects which type of character is being read and then outputs the identity of the character.

An array of integrated photosensitive devices is used to lift an image of a printed character or symbol from a document or other surface, process the image to enhance character information and referencing it against a self adjusting threshold to produce a black/white video output, in serial form, representative of the image sensed by the array. Charge transfer devices are used extensively throughout on a single integrated circuit to provide a complete image processing video device on a single integrated circuit chip.

An improved magnetic image character reading system which produces high signal levels, eliminates dead spots between sample tracks for full resolution. Two sets of read heads are positioned in a spaced apart, staggered arrangement such that one set is adjacent the other with elements of the first set staggered to overlap the tracks read by the second set. Scanned signals generated while passing magnetized characters first past one set and then past the second set of heads are combined after delay of the signal generated by the first set of heads to compensate for spacing between the sets of heads.

An image processor (10) for use with an image sensor (12) is provided. The image sensor includes two output channels (14, 16) for producing video signals in the form of a clock signal carrier which is amplitude modulated by picture element signal levels sensed by the image sensor (12). A first filter (22) is connected to the image sensor (12) for removing the clock signal from the video signals produced by the image sensor which are produced on the first channel (14). A second filter (26) is connected to the image sensor (12) for receiving video signals from the second channel (16) for removing the clock signal from the video signals produced by the image sensor (12) produced on the second channel (16). The filtered video signals are combined in a multiplexer (40) to produce a single video signal.

A document processing system for processing documents having data printed thereon including markings visible to the eye, but which are not to be read by the system and characters which are to be read by the system includes structure for scanning a document for capturing the color image of the document being processed and for generating a plurality of colored picture elements. Circuity is provided for identifying colors included within the core area and edge of the markings. The colors of the picture elements of the core area and edge of the markings are converted to the color of the background of the document thereby generating a filtered image of the document. An optical character recognition unit is provided for receiving the filtered image of the document representing character information only and for identifying the characters appearing on the document from the filtered image, such that the markings and the background surrounding a character are not distinguishable by the optical character recognition unit.
