PROBLEM TO BE SOLVED: To provide a color tone correcting circuit which can correct color tone for only arbitrary hue. SOLUTION: A hue-detecting means for detecting hue component by each pixel, from a first color difference signal R-Y and a second color difference signal B-Y, and a gain control means for controlling a gain every picture element are installed. The gain corresponds to one or arbitrary combination, which are selected arbitrarily from among a luminance signal, the first color difference signal R-Y and the second color difference signal B-Y, according to the hue component by each pixel detected. |
