摘要：
In order to optimize a color conversion table in accordance with environment of a user since a conventional color conversion table used in a printer driver is not optimized in accordance with the environment of the user, when an installer operation is executed by a computer 21 constituting an image processing device 20, a color conversion table 21b2b is formed from a pre conversion color conversion table 21b2c at step S130 and according to a processing of increasing lattice points in this case, the lattice points are increased by nonlinear interpolation calculation using Lagrange interpolation equation at step S430 or the lattice points are increased by linear interpolation, and in that case the number of the lattice points may be fixed or may be a number in accordance with environment or input image by which the color conversion table 21b2b having a pertinent size can be formed from the pre conversion color conversion table 21b2c having a small size.
