Abstract: A current value corresponding to a relationship between an illumination intensity instruction value and illumination intensity is calculated based on a previously obtained relationship between a current flowing through a light emitting device and the illumination intensity. A calibration table including the illumination intensity instruction value, the current value, and the illumination intensity is created. A required illumination intensity is calculated during measurement. An illumination intensity instruction value corresponding to the required illumination intensity is calculated. The illumination intensity instruction value is set using the calibration table.
