Abstract

PURPOSE: To detect a color frame from the pulse width corresponding to the color frame which is outputted from the second pulse generator, by providing the second pulse generator which is reset by an inputted burst signal.
CONSTITUTION: In the color frame detection system where a color frame is detected dependently upon the phase relation between horizontal synchronizing signals and burst signals, the first pulse generator 30 which is controlled to be set by a horizotally synchronizing signal and be reset at a fixed time of a burst signal and the second pulse generator 29 which is set by the pulse trailing edge of the first pulse generator and is reset by the next inputted burst signal are provided, so that a color frame can be detectd in 33 from the pulse width corresponding to the color frame which is outputted from the second pulse generator.
