Abstract
A correction table generation method includes acquiring a first color value of an apparatus non-dependent color system corresponding to an input value of a multi-dimensional apparatus dependent color system in an input lattice point of the color conversion table and generating a multi-dimensional conversion table in which a first apparatus dependent value of the apparatus dependent color system having color conversion table color value characteristics is correlated with a second apparatus dependent value having a color value of the apparatus non-dependent color system and approximate linearity over multiple dimensions, and the generating of the multi-dimensional conversion table includes determining a target color value for multiple dimensions having approximate linearity over the multiple dimensions with respect to the input value, and determining a first apparatus dependent value corresponding to a second apparatus dependent value using the input value, the target color value for the multiple dimensions, and the first color value.
