  • Publication number: 20050088368
    Abstract: The present invention provides a system, method and computer program product for reducing fill and improving quality of interlaced displays using multi-sampling. In an embodiment of the invention, a frame buffer for a interlaced display is filled. Initially, a first multi-sample of the first line of the first field is calculated. The bottom sub-pixels of the first multi-sample are the top sub-pixels of a multi-sample of the first line of the second field. The first multi-sample is written into the frame buffer. Then, a second multi-sample of the second line of the first field is calculated. The top sub-pixels of the second multi-sample are the bottom sub-pixels of a multi-sample of the first line of the second field. Also, the bottom sub-pixels of the second multi-sample are the top sub-pixels of the second line of the second field. The second multi-sample is written into the frame buffer.

  • Patent number: 6377270
    Abstract: A system and method of gamma correction of pixel color coordinates by direct calculation is provided. The response characteristics of a graphics display device are modeled to produce a set of transformation functions. The parameters that describe the transformation functions are then sent to a transformation unit. To display a pixel, the transformation unit evaluates the transformation functions. Color coordinates of the pixel are used as inputs in the evaluation of the transformation functions. This produces transformed pixel color coordinates. The transformed pixel color coordinates are then sent to the graphics display device. The pixel can then be displayed with its originally intended color.
