Abstract
A television strobe effects system is described in which a position information signal representing the position of a moving object included in a television picture is extracted from either the input video signal or the sample-to-sample comparison between successive frames or fields of the input video signal. The write-in of the input video signal in a picture memory is controlled in response to the position information signal so that such write-in for each frame of the input video signal is prohibited at those addresses of the memory which correspond to the position of the moving object.
