ABSTRACT:
If the color reproduction characteristics in a device vary at the time of creation of a profile and at the time of execution of a CMS (color management system) using the profile, a good color reproduction result cannot be obtained as a result of the execution of the CMS. In this invention, therefore, a current characteristic representing the current color reproduction characteristic of the device is acquired, and an estimated characteristic indicating a color reproduction characteristic based on a device profile is acquired. The degree of stability of the current color reproduction characteristic of the device is acquired. Whether the profile properly reflects the current characteristics is determined on the basis of the current characteristic, the estimated characteristic, and the degree of stability. By updating the profile on the basis of the this determination result, optimal color reproduction characteristics are maintained in the device.
