Abstract:
1. A color processing apparatus comprising: a memory that stores a patch set including a plurality of patch colors; a color-difference-accuracy calculating unit that calculates a color difference between a measured color value and a predicted value as a color-difference accuracy, the measured color value corresponding to a target color that has been set in advance, the predicted value being predicted from the target color using a color conversion model that has been generated from the patch set and measured color values corresponding to the plurality of patch colors included in the patch set; an invertibility-accuracy calculating unit that calculates a difference between a predicted target color and the target color as an invertibility accuracy, the predicted target color being predicted, using a model with which transformation is performed in a direction opposite to a direction of transformation using the color conversion model, from the predicted value that has been calculated from the target color using the color conversion model; and an output unit that outputs the color-difference accuracy and the invertibility accuracy.
