  • System and method for blending of spatial interpolation and weaving
    Patent number: 7525599
    Abstract: A method for processing video information may include calculating a plurality of motion indicators for a plurality of pixels in a current field and at least one corresponding plurality of pixels in at least one adjacent field. At least one of the plurality of motion indicators may indicate an amount of weave artifacts that are created, if the plurality of pixels in the current field are woven with the corresponding plurality of pixels in the at least one adjacent field. The calculated plurality of motion indicators may be combined to generate a blend control value that indicates an amount of weaving and spatial interpolation that is to be done for a current output sample value. The current output sample value may be generated based on the generated blend control value.
