ABSTRACT:
A video source provides a temporally interpolated video signal, a spatially interpolated video signal and a motion indicating signal. A difference signal, derived from the temporally and spatially interpolated signals, is symmetrically limited as a function of the motion signal amplitude and then combined with the temporally interpolated signal to form a motion adapted video output signal having (1) reduced motion artifacts such as smearing and loss of fine detail; (2) reduced noise sensitivity; and (3) enhanced low-contrast motion rendition.
