Post de-interlacer motion adaptive filter for smoother moving edges |
摘要 |
A system and method for motion adaptively filtering a de-interlaced video signal. This motion adaptive filtering may be accomplished by using a motion value determined during motion adaptive de-interlacing. The motion value may be used to adjust the amount of filtering to be applied to the de-interlaced signal. Edges in the signal representing motion my be filtered more than static regions. A pixel by pixel difference between multiple signal frames, calculated during motion adaptive de-interlacing, may be used to determine the motion value. A motion adaptive filter may be implemented either separately from the motion adaptive de-interlacer or incorporated as part of the motion adaptive de-interlacer.
