Abstract
PURPOSE: To enable to reject the cross color, by forming the original signal delayed by a given value to the original signal and operating the both original signals.
CONSTITUTION: The original signal(delay signal) including the cross color component in which it is in opposite phase to the original signal and in-phase to the cross color component included in the original signal, is formed and the cross color is rejected by the operational precessing of the both signals. That is, the chroma signal Sc1 picked up and separated at BPF4 is fed to the first processing circuit 10A and the second processing circuit 10B. The processing circuits 10A and 10B are constituted with the delay circuits 12, 14 having specified delay times τ1 and τ2 and the subtractors 13 and 15. Thus, the cross color produced in two directions can be rejected by using the vertical corelativity of chroma signal obtained from two horizontal scanning lines adjacent each other in the circuit 10A and by using the vertical corelativity of chroma signal obtained from the horizontal scanning lines in every other lines in the circuit 10B.
