Abstract:
A color measuring device includes a housing; a sensor unit configured to capture an image of a region, the sensor unit being held to the housing; an illumination light source configured to illuminate the region, the illumination light source being held to the housing; a detecting unit configured to detect a distance between predetermined two points from image data of the region obtained by the sensor unit; a correcting unit configured to correct the image data including a subject whose color is to be measured according to a ratio of the detected distance to a reference distance; and a calculating unit configured to calculate a colorimetric value of the subject based on the corrected image data.
