Abstract:
In a case that a cleaning mode is designated, it is determined whether or not a lens unit is attached to a camera main body. If it is determined that the lens unit is not attached to the camera main body, a quick return mirror is moved upward and a shutter is opened, and a photoelectric conversion device, or a cover glass or an optical filter of the photoelectric conversion device is vibrated, thereby foreign substances attached to the photoelectric conversion device and the like are removed.
