Provided is Electronic apparatus having a function of first power mode and a function of second power mode where power consumption is smaller than first power mode. A plurality of detecting units detects a plurality of trigger operations in second power mode, each of the trigger operations serving as a trigger that causes Electronic apparatus to return from second power mode to first power mode. Mode switching unit causes Electronic apparatus to return from second power mode to first power mode when any one of the plurality of trigger operations is detected by the plurality of detecting units. Power control unit supplies power to the plurality of detecting units in second power mode while performing control of repeating a supply period where power is supplied to the detecting unit and a non-supply period where power is not supplied to it in respect to each of the plurality of detecting units.
