Abstract: In a colorimetry device and a colorimetry method of the present invention, reference chart definition information including at least reference chart identification information about a reference color chart and patch position definition information indicating a position of each of plurality of patches in the reference color chart is stored, and whether the obtained color chart is matched with the reference color chart is determined based on the reference chart identification information. When the obtained color chart is determined to be matched with the reference color chart, a position of a colorimetry unit with respect to the color chart is relatively moved to the position of each of the plurality of patches in the color chart based on the reference chart definition information, and the colorimetry unit measures the color of each of the plurality of patches.
