Zusammenfassung:	An electronic camera adopts an image pickup and optical system of a mirror scan type in which a mirror for scanning is disposed at a forward side of a taking lens. A line image sensor relatively scans an object while rotating the mirror to perform photographing. When controlling the exposure, the taking lens is moved synchronously along with rotation of the mirror to adjust the focal position thereof each time a slender sub-image of the object is picked up by the CCD. Driving the taking lens to focus the sub-image each time of scanning the sub-image enables picking up an entirety of the object image perfectly in a focused state.
