  • Method for improving quality in graphics pipelines through a frame's top and bottom field processing with conditional thresholding and weighting techniques
    Patent number: 6788312
    Abstract: A system, method and computer program product are provided for improving image quality in a graphics pipeline. Initially, a difference is detected between a first pixel of a first frame to be outputted and a corresponding second pixel of a second frame outputted before the first frame. Such difference may be representative of motion which is capable of reducing image quality. A pixel output is then modified if such a difference is detected. This is accomplished utilizing texturing hardware in the graphics pipeline. Thereafter, the pixel output is outputted via a progressive or interlaced display system.

  • Super-sampling and multi-sampling system and method for antialiasing
    Patent number: 6720975
    Abstract: A system, method, and computer program product are provided for antialiasing during rendering in a graphics pipeline. Initially, a primitive of vertex data is received in a graphics pipeline. Next, a super-sampling operation is performed on the primitive of vertex data ufilizing the graphics pipeline. Further, a multi-sampling operation is performed on the primitive of vertex data utilizing the graphics pipeline.
