After a fixed period of time has passed with no operation received by an operating unit, a control unit switches the operation mode to a first power saving mode when the brightness detected by a brightness detection unit is greater than or equal to a given brightness, and switches the operation mode to a second power saving mode when the brightness detected is less than the given brightness. The control unit extends the detection range of a human detection unit in the second power saving mode to a range broader than the range used in the first power saving mode.
