Abstract
A control unit calculates the color temperature using at least a first visible light signal and a near-infrared signal when the amount of the near-infrared signal is larger than a predetermined amount. The first visible light signal is a signal generated by photoelectrically converting visible light. The near-infrared signal is a signal generated by photoelectrically converting near-infrared light.
