Abstract
PURPOSE: To reduce color slippage and color smear to improve the transient response of a color signal by detecting change of video signal to arrange the polarity of the output into one direction and by using signal to control the gain of primary signals or color difference signals.
CONSTITUTION: Video signals from delay line 6 are applied to differentiating circuit 7, and an output signal according to change of these signals is applied to shaping circuit 8. In circuit 8, the other polarity-side signals are converted to one polarity-side signals to arrange signals into the same polarity, and the gain of gain control circuit 9 is controlled by output signals with polarity arranged. The signal of color signal processing circuit 5 is processed by color difference signal demodulator circuit 51 and is applied to circuit 9. By utilizing the change part of video signals to correct signals, color slippage and color smear are prevented to improve the transient response of color signals and improve segmentation of color to improve the picture quality.
