Device and method for determining appropriate color patch measurement operation by user based on acquired and predicted measurement values

A determination device comprising:

• a first instructing unit that instructs an image output device to output a first patch column in which a plurality of single-color patch images and at least one multicolor patch image are arranged, the plurality of single-color patch images being represented by respective tone values for single colors, the one multicolor patch image being represented by a tone value of a multicolor;
• a first acquiring unit that acquires measurement values of the plurality of single-color patch images measured by a user by operating a measurement device along a first patch column output by the image output device;
• a correcting unit that corrects the tone values on a per color basis such that the measurement values, of the plurality of single-color patch images acquired by the first acquiring unit are made to approach target values predetermined for the single-color patch images;
• a predicting unit that predicts a measurement value of the multicolor patch image included in a second patch column to be output by the image output device, the second patch column being acquired after the correcting unit corrects the tone values in the first patch column;
• a second instructing unit that instructs the image output device to output the second patch column;
• a second acquiring unit that acquires the measurement value of the multicolor patch image measured by performing, by the user, an operation of the measurement device along the second patch column output by the image output device;
• and
• a determining unit that determines whether the operation performed by the user is appropriate on a basis of the measurement value acquired by the second acquiring unit and the measurement value predicted by the predicting unit.
