ABSTRACT:
A transition detector is disclosed which compares comb filtered component signals from adjacent image lines. A detector detects signals in the band of frequencies normally occupied by color representative information for a given line and two adjacent lines. A control signal generator generates a control signal in response to the relative levels of the detected signals for the given line, and the lines adjacent the given line. The composition of the comb filtered component signal coupled from the comb filter to the component processing channel is altered in response to the generated control signal.
