Color reproduction system

摘要

A color space data conversion formula corresponding to the input and output conditions can be selected from basic profiles which consists of a plurality of the conversion formulas for color reproduction processes. A plurality of parameters or a plurality of variable conversion formulas can be selected from subprofiles, in accordance with the input and output conditions and on the ground of the color space data conversion formula selected from the basic profiles. Basic profiles or subprofiles can be added or modified. The color image data are processed highly accurately to obtain color images of high reproducibility, for thereby facilitating the setting of the input and output conditions.
