Abstract
The luminance signal-color signal separating circuit obtains signals of three lines by a 1H delaying circuit. Further, by unit delaying circuits, signals at three points are obtained in each line. Thus, signals at nine points continued vertically and horizontally are input into a color signal detecting circuit which determines an oblique correlation of the signals at these nine points to thereby obtain the degree of the color. The color signal detecting circuit obtains a color signal output having had the oblique luminance component removed by the operation of the color signal component from a three-line color separating circuit and the degree of the color.
