Granularity level adjustment areas, in each of which a granularity level of an image is adjusted, are extracted. Each of target values for the granularity levels in the extracted granularity level adjustment areas is set. The granularity level is calculated, and the device color signals in the granularity level adjustment areas are converted, such that the calculated granularity level is closer to the target value than before the device color signals are converted, and such that the new device color signals fall within an isochromatic range in a device-independent color space. |
