摘要：
A color measuring device include an illuminating unit configured to illuminate an image-capturing range; an image capturing unit configured to capture an image of the image-capturing range containing a patch and an object; an extracting unit configured to extract image data of a surrounding region in a predetermined color from the image data output by the image capturing unit; an interpolating unit configured to interpolate at least one target region that is at least one of regions of the patch and the object based on the image data of the surrounding region; a storage unit configured to store therein, as correction data, interporting data that is interporated; a correcting unit configured to correct the image data output by the image capturing unit by using the correction data; and a calculating unit configured to calculate a colorimetric value of the object based on the corrected image data.
