ABSTRACT:
The objective of the present invention is to enhance a specific color without changing the hue of an original image.At least two different gray-level correction functions are provided for luminance signals input for three colors, R, G and B, and these functions are used to calculate correction coefficients for the individual colors. Then, the luminance signals input for the three colors are synthesized so that the weighting of the colors is changed in accordance with the input luminance signals, and a correction coefficient is calculated that is used in common. The input signals are then multiplied by the thus obtained correction coefficient.
