Abstract
A colorimetry device includes: a colorimetry unit including an irradiation unit including a substrate provided with a LED, and a light-receiving unit configured to receive reflected light that is light irradiated from the LED and reflected by the color chart image, the colorimetry unit being configured to perform colorimetry of the color chart image; a movement unit configured to cause the colorimetry unit to reciprocate along an intersecting direction; a calibration member provided in the intersecting direction; a temperature sensor configured to detect a temperature of the LED or a temperature of the substrate; and a colorimetry device control unit configured to move the colorimetry unit by the movement unit to a calibration member and calibrate the colorimetry unit when determining that the colorimetry unit is to be calibrated for the colorimetry of the color chart image based on the temperature detected by the temperature sensor.
