Abstract of the Disclosure A control signal spreader for ameliorating undesirable effects of abrupt changes in a control signal in a video signal processor gradually changes the magnitude of the control signal in the horizontal, vertical and temporal dimensions of the video signal. The control signal is applied to a first circuit means, which, responsive to positive transitions of the control signal, generates a gradually increasing signal and provides the lesser valued one of the control signal and the generated signal. A delayed version of the control signal is applied to a second circuit means, which, responsive to negative transitions of the control signal, generates a gradually decaying signal and provides the greater valued one of the control signal and the generated decaying signal. The first and second circuit means are coupled to a third circuit which provides as an output control signal, the greater valued signal provided by the first and second circuit means.
