Abstract
When a color-reproducibility precision is determined with a plurality of evaluation colors, an overall color-reproducibility precision needs to be obtained with the plurality of evaluation colors to evaluate color reproducibility with a high precision. A color-evaluation-scale calculation section calculates color differences and metrics from the input colorimetric values of a reference image and the input colorimetric values of an image to be evaluated, for a plurality of evaluation colors, and computes a plurality of color-evaluation scales indicating a color-reproducibility precision of the image to be evaluated, according to the calculated color differences and metrics.
