  • Method and apparatus for high-speed electronic data signal modification and improvement
    Patent number: 5091971
    Abstract: A method and apparatus for modifying an image data signal has a serial channel for obtaining a desired number of current M-bit patterns from the image data. Unique bit patterns are recognized in the current bit patterns, and new bit patterns are generated, each being specific to the detected unique bit pattern. The current and new bit patterns are combined in a predetermined manner to modify the image data as desired. For example, if the unique bit patterns are recognized as dark images on a leading edge of an image, the new bit patterns are generated and combined with the current bit patterns to lighten the image, particularly at the leading edge to improve stripping of the print media on which the image is printed from a fuser roll of the printer.
