A digital camera includes an optical system including a focus lens, a zoom lens and a diaphragm, an HDMI output terminal configured to output sound collected by a microphone unit and a picture imaged by a CCD image sensor to an external recorder, and a controller. The controller controls switching between a moving image priority mode and a still image priority mode in which the optical system is driven at a higher speed than a speed in a moving image priority mode. In addition, the controller allows change to a moving image imaging mode by an operation unit when detecting that output to the external recorder is possible in the HDMI output terminal.
