The control unit performs a calibration process in such a manner that an image of a color chart having a plurality of color patches with known chromaticity values is captured by an imaging element, chromaticity for each of the plurality of color patches is obtained from an imaging signal of the color chart, and the contents of the color correction table are changed.
