Abstract
In a camera having a power source shared between a charging circuit for a strobe emission and a camera function section other than the charging circuit, the charging operation is inhibited during an operation of the camera function section and a battery check is inhibited during the charging operation. As a result, a runaway of a CPU of the camera due to the voltage reduction of the power source in the charging operation is avoided; moreover, inhibition of a shooting operation due to the battery check is prevented, thereby efficiently utilizing the battery capacity.
