ABSTRACT:
When discharge power calculated based on a current value detected by a current detector is smaller than expected maximum power, which is the maximum power expected in an actual operation, a discharge efficiency at the expected maximum power is set as a discharge efficiency used for remaining capacity calculation. This ensures that a remaining capacity based on power required for a photographing operation can be detected.
