ABSTRACT:
In a picture-quality improving circuit, a luminance transition is detected on the basis of a luminance signal. Chroma edge characteristics of a color signal are enhanced in accordance with the detected luminance transition. A detection is made as to whether the color signal and the luminance signal are correlated or uncorrelated in transition. When the color signal and the luminance signal are uncorrelated in transition, the enhancement of the chroma edge characteristics of the color signal is interrupted.
