Color conversion definition creation method, color conversion definition creation apparatus and color conversion definition creation program storage medium

A color conversion definition creation program storage medium storing a color conversion definition creation program to be incorporated in and executed by a computer, for causing the computer to create a color conversion definition in which correspondence relation between coordinates in the first space and coordinates in the second space is defined, the program configuring, on the computer:

• an acquisition section which acquires a group of pairs of a coordinate in the first color space and a coordinate in the second color space;
• a setting section which sets nonlinearity in the correspondence relation between the coordinates in the first color space and the coordinates in the second color space;
• and
• a calculation section which solves a formula in which, for any two coordinates in the first color space, mutual relation between coordinates in the second color space corresponding to the coordinates in the first color space is generally specified, with the group of coordinate pairs acquired by the acquisition section as a boundary condition and with the nonlinearity set by the setting section added, to calculate each coordinate in the second color space corresponding to each coordinate in the first color space;
• a creation and output section which creates and outputs the color conversion definition by using the coordinate calculated in the calculation section.
