Color difference display control apparatus, color difference display control method, and control program

A color difference display control apparatus comprising:

• an input unit adapted to input data associated with spectral reflectances of respective patches on a first measurement chart and a second measurement chart which record a plurality of color patches;
• a computing unit adapted to compute color difference values between the patches corresponding to identical positions on the first measurement chart and the second measurement chart based on the data input in the inputting step;
• an icon display unit adapted to display the plurality of computed color difference values as a plurality of patch icons;
• a first display unit adapted to display the color difference values represented by the patch icons in a first display format that displays, as numeric values, the color difference values within display regions of the corresponding patch icons;
• and
• a second display unit adapted to display the color difference values represented by the patch icons in a second display format that displays, as numeric values, the color difference values above display regions of a plurality of patch icons.

A computer-readable storage medium storing a computer program for making a computer execute a color difference display control method, said method comprising:

• a step of inputting data associated with spectral reflectances of respective patches on a first measurement chart and a second measurement chart which record a plurality of color patches;
• a step of computing color difference values between the patches corresponding to identical positions on the first measurement chart and the second measurement chart based on the data input in the inputting step;
• a icon displaying step of displaying the plurality of computed color difference values as a plurality of patch icons;
• a step of displaying the color difference values represented by the patch icons in a first display format that displays, as numeric values, the color difference values within display regions of the corresponding patch icons;
• and
• a step of displaying the color difference values represented by the patch icons in a second display format that displays, as numeric values, the color difference values above display regions of a plurality of patch icons.
