  • Method and apparatus for determining mis-registration
    Patent number: 5592573
    Abstract: An image processing apparatus includes a data acquisition stage for acquiring data representative of several spatially separated regions of a sample. The apparatus also includes data storage means for storing reference data corresponding to the sample data. The two sets of data are compiled and analyzed to determine if the sample is shifted from a nominal position.
    Type: Grant
    Filed: October 11, 1994
    Date of Patent: January 7, 1997
    Assignee: De La Rue Giori S.A.
    Inventors: Christoph Eisenbarth, Ira Finkelstein, Dennis McGhie, Edward Panofsky
  • Apparatus for image acquisition with speed compensation
    Patent number: 5530562
    Abstract: An image acquisition system includes a transport mechanism for transporting sheets of objects past a sensor. The sensor scans the objects and generates data streams which are scaled by a multiplier to compensate for the speed variation of the transport mechanism. At speeds much lower than a nominal speed, the scanning rate of the sensor is increased to generate several data streams for each scanned line, which are then combined in a single speed corrected signal stream for further processing.

    Filed: August 6, 1992
    Date of Patent: June 25, 1996
    Assignee: De La Rue Giori S.A.
    Inventors: Christoph Eisenbarth, Ira Finkelstein, Dennis McGhie, Edward Panofsky
  • Method and apparatus for monitoring image processing operations
    Patent number: 5394486
    Abstract: An image processing system with self monitoring includes an image acquisition module for acquiring data corresponding to an image, and one or more image processing modules. The acquisition module interleaves the variable (and therefore unpredictable) image data with diagnostic data to provide known diagnostic data. The image processing modules process the diagnostic data together with the image data to monitor system performance.
