摘要： Color reproducibility needs to be evaluated in consideration of the influence of homogeneity in page image. Hence, a first chart is formed from an image of a uniform density of a region to be evaluated, and data associated with the spectral reflectances of plural points on the first chart are input. Based on the data obtained from the first chart, color differences between a predetermined point and other points on the first chart are calculated. When the calculated color differences fall within a permissible range of heterogeneity of colors in the region, a second chart is formed from an image corresponding to a color target, and data associated with the spectral reflectances of plural points on the second chart are input. Color differences are calculated from the data obtained from the second chart and data associated with the spectral reflectance of the color target.

摘要： This invention provides a display apparatus, control method, and control program, which display hue differences and color difference values of respective patches as lists, and display the hue direction of the hue difference of each individual patch on a chromaticity diagram in an easy-to-understand manner. To accomplish this, a display method of this invention includes a specifying step of specifying a color determined by a hue difference calculated from first and second values associated with spectral reflectance characteristics, and a display step of displaying the color specified in the specifying step as a graphical object. The specified color is specified as a representative color that indicates a hue on a chromaticity diagram to which the hue difference biases.

摘要： Upon observing homogeneity in page image by the human eye, a permissible level associated with color reproduction with respect to an identical color signal changes depending on the distance from an interest point. Since the conventional homogeneity in page image evaluation scheme doesn't take the above characteristics into consideration, the correlation between a finished image and the evaluation result cannot be exploited fully. Hence, image data, which forms an image with identical density within a range to be evaluated in one page, is output to a printer to measure reflection characteristics of the image at points on output of the printer. One point is set as a reference point, and distances between the reference point and the remaining points, and differences of the reflection characteristic between the reference point and the remaining points are calculated. The image quality within the range is evaluated based on the distances and differences.
