  • Systems and methods for improving image quality using digital signal processing techniques
    Patent number: 7860348
    Abstract: A compensating technique, implemented as an image processing block inserted in a chain of sequential image processing blocks, is used to achieve custom tuning at an end-user site to provide a customer a desired image quality (IQ) different from the factory calibrated one, or to simply compensate for drift in the image quality due to a number of factors including environmental conditions and/or system aging. The compensating techniques use a higher order polynomial to correct an actual input/output parameter relationship such that it is acceptably close to a pre-determined input/output parameter relationship for a given measurable parameter related IQ.
    Type: Grant
    Filed: July 13, 2007
    Date of Patent: December 28, 2010
    Assignee: Xerox Corporation
    Inventors: Michael J. Wilsher, Andre Blaakman, Kristy Leeming
