CA 2070543

In a motion detector operative on a composite video signal comprising chrominance, signal components as well as a luminance signal component, the chrominance signal components are suppressed by a filter that removes only diagonal high frequencies in the spatial-frequency domain. These diagonal high frequencies in the spatial-frequency domain include the chrominance signal components of the composite video signal in accordance with a standard such as the NTSC standard. Motion detection is improved by reason of including more of the spatial high-frequency components.
