ABSTRACT:
A system for improving color picture qualities in which in response to the output signal representative of whether the transient portion of the luminance signal Y and the color difference signal (C-Y), where C is R, G or B, is in the same direction or in the opposite directions, the high-frequency component in the luminance signal is so controlled as to provide the correction signal which serves to improve the contour lines of the images in the reproduced color picture.
