A method and an apparatus are provided for correcting the frequency characteristics of a carrier chrominance signal, which, by use of the correcting signal for the frequency characteristic involved in a vertical blanking interval, determine whether the frequency characteristics of the carrier chrominance signal are distorted and correct the frequency characteristics. A band pass filter is used which determines a degree of the frequency characteristic distortion of the carrier chrominance signal band from the correcting signal for the frequency characteristic, and has a gain in accordance with the determined result. If the frequency characteristic of the carrier chrominance signal involved in the input composite video signal is distorted by the frequency characteristics and so on of the analog broadcasting radio channel and the broadcasting receiver, the distortion is corrected whereby a stable reproduction of the color signal is possible irrespective of the broadcasting channels and the broadcasting receiver.
