ABSTRACT:
There is provided a method of generating a tone correction table used to correct tone characteristics of image data of each component color in a color image forming apparatus, comprising the steps of outputting color patch images of each component color for respective tone levels corresponding to a plurality of different image data values, acquiring colorimetric values including brightness values, chromatic values, and reflection spectra of respective patches by measuring colors of the output color patch images, analyzing characteristics of the calorimetric values for respective tone levels based on the calorimetric values of the color patch images, selecting a tone correction table generation method according to the characteristics obtained in the analysis step, and generating a tone correction table to have tone characteristics as target characteristics according to the selected tone correction table generation method.
