Patent ID: 8730254

Claim:
A color processing apparatus for color matching between an image displayed on a monitor device and an image printed by a printer device under a same viewing condition, the color processing apparatus comprising: a device characteristic acquisition unit configured to acquire a monitor device characteristic including black tristimulus values from a monitor device profile of the monitor device; a viewing condition acquisition unit configured to acquire an output viewing condition from a printer device profile of a printer device without measuring the output viewing condition; a correction unit configured to correct the monitor device characteristic so as to correct the black tristimulus values of the monitor device characteristic based on the output viewing condition to obtain correction values; a determination unit configured to determine whether to perform correction of a value of the monitor device characteristic based on a result of comparing a luminance value of the correction values and a luminance value of the black tristimulus values, wherein, if the luminance value of the correction values is greater than the luminance value of the black tristimulus values, the correction unit is further configured to correct the luminance value of the black tristimulus values so that the corrected luminance value of the black tristimulus values is greater than or equal to the luminance value of the correction values; and a color conversion unit configured to perform color conversion based on the output viewing condition and the corrected luminance value of the monitor device characteristic, wherein the device characteristic acquisition unit is configured to acquire a printer device characteristic in addition to the monitor device characteristic, and the color conversion unit is configured to perform color conversion for matching an input image displayed on the monitor device with an output image to be output by the printer device.
