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.

Abstract: According to a surface defect inspection device and a surface defect inspection method according to the present invention, an inspection face of an inspection object is irradiated with illumination light, and a defect at the inspection face is detected, based on an image including the inspection face captured. According to the surface defect inspection device and the surface defect inspection method, the illumination light is emitted with formation of at least one set of a light region and a dark region, and a range of a defect detection image region for the detection of the defect, to be set to the image capturing the inspection face irradiated with the illumination light in the light region, is adjusted in accordance with a previously defined degree of visibility for orange peel, at the detection of the defect at the inspection face.
