  • Read-out level compensation in an optical reader system
    Patent number: 4383275
    Abstract: An optical reader system includes a plurality of sensor elements for providing a picture signal. Before initiating an actual reading operation, a white background plate is scanned to obtain reference information. The white background plate data is reversed to obtain a reciprocal of the white level and the thus obtained reciprocal is memorized in a memory. In an actual reading operation, the picture signal derived from the sensor elements is multiplied by the reciprocal memorized in the memory to compensate for the nonuniformity of the sensor outputs.
