ABSTRACT:
To provide a method for generating color-correction lookup table for better using a color reproduction area of an output system, an image processing apparatus, an image processing method, and a recording medium.An image processing apparatus uses a color-correction lookup table to apply a desired color correction to an input image signal. The image processing apparatus is provided with a color-correction lookup table for chroma enhancement, which applies chroma-enhancement processing to a desired color point in the input image signal in an area where an output system gamut is wider than an input system gamut, and uses the color-correction lookup table for chroma enhancement according to the input image signal for performing the desired color correction. The color-correction lookup table for chroma enhancement does not perform the chroma-enhancement processing when the desired color point is close to achromatic color.
