Abstract:
1. An evaluation apparatus for evaluating the color reproducibility of a device which processes a color image, comprising: calculation means for calculating at least one of color differences and metrics from the colorimetric values of a reference image and the colorimetric values of an image to be evaluated, for a plurality of input evaluation colors; computation means for computing a plurality of color-evaluation scales indicating a color-reproduction precision of the image to be evaluated, according to at least one of the calculated color differences and metrics; generation means for generating display data used for displaying the plurality of color-evaluation scales; and display means for displaying, as the color-evaluation scales, at least two of a color reproduction index and an accumulative-probability distribution graph, a color-difference statistic and a color-difference histogram, a metric statistic and a metric histogram, a color-difference distribution chart and a metric distribution chart, and a colorimetric score table.
