Abstract: In a digital still camera, when the reproducing mode is selected, an indication to the effect that the operation is in standby for reproduction is displayed on an indicating device, and if the command dial is not operated until 16 seconds elapses after the indication has been started, the supply of source voltage to the various parts of the camera is stopped, to achieve a reduction in power consumption. If the command dial is operated within 16 seconds, image signals are output to an external monitor and also an indication to the effect that reproduction is in progress is displayed on the indicating device. If the command dial has been operated within three minutes after reproduction of a given photographic frame has been started, reproduction of the following frame is performed, but if the command dial has not been operated until the three minutes have elapsed, the indication to the effect that the operation is in standby for reproduction is displayed again.
