Abstract
A color conversion table is generated by estimating a device color corresponding to the color of a grid point forming the color conversion table from a calorimetric value obtained by calorimetrically measuring a color of a gamut reproduced by an output device. In addition to the color of the grid point forming the color conversion table, a device color corresponding to a color other than that of the grid point is estimated. The generated color conversion table is corrected using the estimated device color corresponding to the color of the grid point and the estimated device color corresponding to the color other than that of the grid point.
