Abstract
A motion signal is formed by subtracting an undelayed and a delayed video signal and by subsequently forming the absolute value. An amplitude maximum of the motion signal is initially determined within a search window and subsequently a minimum corresponding to the noise peak value is determined from the maximum values of a plurality of search windows.
