Abstract
A detector for detecting motion in an image represented by a video signal includes delay elements for providing lines of signal from five consecutive fields. Sums of signals from first and second fields are subtracted from sums of signals from third and fourth fields to generate first motion indicators. Differences of signals from the first and second fields are subtracted from differences of signals from the third and fourth fields to generate second motion indicators. Differences of signals from the first and fifth fields are generated to form third motion indicators. The first, second and third motion indicators are compared and the largest is provided as a motion signal which is subsequently limited, spread and scaled. Signals used in forming the motion indicators are selected to substantially reject any adverse influence of the chrominance subcarrier.
