ABSTRACT:
Successive video signals of a first frame and a second frame are received. A signal difference between the video signals is determined and filtered to obtain a luminance difference. A signal sum of the video signals is determined and filtered to obtain a luminance sum. The luminance sum is subtracted from the signal sum to obtain a chrominance difference.
