An image processing apparatus for correcting a hue and a saturation in an input video signal of a moving picture in real time is disclosed wherein the image processing apparatus includes an extracting unit for extracting the hue and the saturation from the input video signal, a determining unit for determining a correcting amount according to the hue and the saturation extracted in the extracting unit, and a correcting unit for correcting the hue and the saturation of the input video signal based on the determination result of the determining unit. Thereby, a desired signal portion of the input video signal is arbitrary corrected in response to the hue and saturation in real time.
