1. An apparatus for reducing noise and motion artifacts in pixels of a displayable video image by filtering pixel values of the pixels based on a first frame of video having filtered pixel values and a second frame of video having unfiltered pixel values, the apparatus comprising: a subtractor to produce difference values by computing a difference between the filtered pixel values of the first frame and the unfiltered pixel values of the second frame; a spatial filter, associated with the subtractor, to compute a motion value of a pixel of interest in the first frame of video by averaging the difference values of pre-selected pixels surrounding the pixel of interest; and a temporal filter, coupled to the spatial filter, to receive the motion value and filter the pixel value of the pixel of interest according to the motion value.
