  • Publication number: 20100060082
    Abstract: A digital camera includes: a battery installation part connectable to either an AC adapter or a battery; a mechanical shutter and a diaphragm; and a controller for supplying, to the mechanical shutter and the diaphragm, power from the AC adapter or battery that is connected to the battery installation part. The controller monitors a voltage output through the battery installation part during the power supply to the mechanical shutter and the diaphragm, and determines whether or not the AC adapter is connected to the battery installation part in accordance with the behavior of the monitored voltage changes.
