Patents by Inventor Ronald C. Slutz

Ronald C. Slutz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Image data processing methods, image data processing apparatuses and scanner systems
    Patent number: 7031024
    Abstract: The method of the invention corrects for a color shift in a color scan mechanism. The method initially senses plural component color data that is derived from the color scan mechanism. A determination is made of whether at least one color component value exhibits a value that exceeds a first threshold. The method also determines if another color component exhibits a value that exceeds a second threshold. If it is determined that both of the color components exceed the respective thresholds, then the one color component value is altered to a predetermined desired color value, so as to correct for color shift.
    Type: Grant
