description In a video system, a method and system for combining results of mosquito noise reduction and block noise reduction are provided. Noise artifacts may be reduced in a video image by generating a first pixel correction value that combines a first and a second noise reduction parameters utilizing a first combination operation. Combining the first pixel correction value and a third noise reduction parameter utilizing a second combination operation may generate a second pixel correction value. New pixel values may be determined for the video image by adding an original pixel value and the pixel correction value. The noise reduction parameters may correspond to results from mosquito and block noise reduction operations. The first and second combination operations may be selected to be a maximum, a minimum, or an addition of the input parameters based on the sign of the input parameters.
