Claim:
1. A color processing apparatus comprising: a control unit configured to control capturing conditions and capturing of an imaging apparatus which captures a plurality of color patches displayed on a monitor; an input unit configured to input imaging data from the imaging apparatus; and a calculation unit configured to calculate measurement values of the plurality of color patches from the imaging data using color conversion characteristics corresponding to the capturing conditions, wherein the calculation unit classifies a pixel value of each color patch indicated by the imaging data into one of first to fourth classifications, calculates the measurement values from the pixel values of the first to third classifications, and no measurement value is calculated from the pixel values of the fourth classification, wherein the first classification is equal to or greater than a first threshold value and less than a second threshold value, the second classification is equal to or greater than the second threshold value and less than a third threshold value, the third classification is equal to or greater than the third threshold value and less than a fourth threshold value, and the fourth classification is less than the first threshold value or equal to or greater than the fourth threshold value, wherein the control unit sets first capturing conditions used at start of the capturing for the calculation of measurement values based on the imaging data captured by the imaging apparatus using initial capturing conditions, and after the capturing for the calculation of measurement values is started, when the imaging data is input, the control unit determines whether or not perform the capturing by changing the capturing conditions.
