Abstract:
1. A digital camera, which has a control unit which regularly carries out an automatic focusing operation without a release button on an operation section being pressed, comprising: a voltage detection unit which detects a voltage of a power supply; a temperature detection unit which detects an inner temperature and an outer temperature of the digital camera; a power supply detection unit which detects whether the power supply is an AC power supply or a DC power supply; a power-supply condition control unit which makes a determination as to a power-supply state of the digital camera based upon a voltage, a temperature and the kind of the power supply that have been respectively detected by the voltage detection unit, the temperature detection unit, and the power supply detection unit; and a focusing unit which automatically focuses a focus lens system onto a subject, wherein the gap of automatic focusing timing is varied by an output from the power-supply condition control unit.
