  • Block-oriented pixel filter
    Patent number: 6711301
    Abstract: A method and apparatus for block-oriented pixel filtering reduces the number of hardware multipliers required for an image processing operation by increasing the speed of the pixel filter and rearranging the math operations. A sorter is employed in the line buffers so that defined groups of input pixel components are provided to the multipliers of the pixel filter. An accumulator is employed to receive products from the multipliers and assemble output pixels. The savings in gate count from reducing the number of multipliers is greater than additional costs, if any, of the sorter and other logic. The method and apparatus of the invention also simplify the addressing logic for the provision of scaling coefficients during an image processing operation.

  • Motion adaptive deinterlacing
    Patent number: 6459455
    Abstract: A method and apparatus for deinterlacing video frames selects a location for deinterlacing, and measures motion at that location. A deinterlacing method is selected based on the measured motion. A pixel value is created for the location.
