Patent ID: 8902464

Claim:
A color processing apparatus comprising at least a processor and a memory that implement: an input unit configured to input plural measurement values obtained by measuring a plurality of color patches included in a color chart; an estimator configured to estimate measurement values of a first number of color patches of the plurality of color patches, which are included in the color chart, other than a second number of color patches of the plurality of color patches, which are disposed at an end of the color chart, using the input measurement values of the second number of color patches, wherein the first number of color patches is greater than the second number of color patches; a calculator configured to calculate color differences between the estimated measurement values and the input measurement values of the first number of color patches; a determiner configured to determine whether or not printing of the first number of color patches or measurement of the first number of color patches has been performed correctly, based on the color differences; and a changing unit configured to change an order of the input plural measurement values in a case where the determiner determines that the measurement has not been performed correctly, wherein the estimator, the calculator, and the determiner repeat their respective processes using the measurement values whose order has been changed.
