摘要:
A method of noise filter parameter adaptation, the method comprising receiving a current video frame comprising a plurality of pixels. A table lookup is performed, using current statistical values associated with the current video frame. Noise filter parameters are adapted, based on current lighting conditions as determined from the performed table lookup. The current lighting conditions correspond to the current statistical values. The current video frame is noise filtered as defined by the adapted noise filter parameters.
