PROBLEM TO BE SOLVED: To provide a colorimetry device for obtaining an uniform colorimetric value while considering cost.SOLUTION: The colorimetry device performs colorimetry by a patch for colorimetry including a foundation and a plurality of patch rows where arbitrary gradation is expressed. The colorimetry device includes: a detection means that includes a plurality of sensors having high sensitivity to an arbitrary wavelength region and detects the reflectance of the foundation and that of each patch in the respective patch rows; and a colorimetric value calculation means of calculating a colorimetric value of each patch based on the relative reflectance of the patch on the basis of the reflectance of the foundation. |
