A color image processing apparatus extracts foreground image data and background image data from whole image data, and corrects one or more among hue, value and chroma of the foreground image data based on one or more among hue, value and chroma of the background image data, thereby reproducing colors by means of correcting a color contrast phenomenon that appearances of the image change in response to an image of the background image data, and allowing color reproduction with high fidelity visually.
