Abstract
In each of various motion detectors operative on composite video signal comprising chrominance component signals as well as a luminance component signal, the chrominance component signals are suppressed with 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 if it is in accordance with an appropriate standard, such as that employed by broadcasters in the United States of America. Motion detection is improved by reason of including more of the spatial high-frequency components.
