Abstract: Disclosed is a digital camera with a live view display function, which is designed to make dust less noticeable. The digital camera includes an image pickup device that receives a subject light flux which has passed a photographing lens and outputs a subject image signal, a dust-proof optical element arranged in front of the imaging surface of the image pickup device, and a display device that provides a live view display of the subject as a move image based on the output of the image pickup device. The digital camera executes a dust removal operation of vibrating the dust-proof optical element in response to initiation or stop of a live view display by the display device.

Abstract: A flash device includes at least one light emitting unit is attachable to a plurality of connection portions. A shielding portion shields the connection portion without an attached light emitting unit. A capacitor accumulates an electric charges and is charged by a charging circuit. A control circuit includes judges both (1) whether or not all the plurality of connection portions are shielded and (2) whether or not the light emitting unit is attached to at least one of the plurality of connection portions, and permits the capacitor to be charged if both all the connection portions are shielded and the light emitting unit is attached to at least one of the plurality of connection portions.

Abstract: A flash device includes at least one light emitting unit. At least one light emitting unit is attachable to a plurality of connection portions. A shielding portion shields the connection portion to which the light emitting unit is not attached. A capacitor accumulates an electric charges. A charging circuit charges the capacitor. A control circuit includes a first judgment section to judge whether or not all the plurality of connection portions are shielded and a second judgment section to judge whether or not the light emitting unit is attached to at least one of the plurality of connection portions, and permits an electric charges accumulation operation into the capacitor in a case where the first judgment section judges that all the connection portions are shielded and the second judgment section judges that the light emitting unit is attached to at least one of the plurality of connection portions.
