A control unit performs calibration when a determining unit determines that an absence condition of an operator is satisfied. Calibration is performed to a whole or part of brightness, a white point (gain), gamma (gradation), and primary colors (red, blue, and green colors). The control unit stores a correction amount by calibration in a storage unit, measures the (corrected) calibrated brightness or color tone by using an optical sensor, and stores the measured final measurement result in the storage unit as a corrected measurement value. After performing calibration or when the determining unit determines that a presence condition of the operator is satisfied, a profile generating unit generates color space information.
