PROBLEM TO BE SOLVED: To obtain an image in which any focal shift is not generated with compact and simple configurations by installing an optical correction system without installing any mechanism for following up focal shift with high precision in macro-photographing. SOLUTION: A focus range is determined on the basis of an object distance, focal distance, and aperture value after an auto-focus operation. When SW2 is operated, exposure is performed only during a period in which a displacement of the optical apparatus due to blur in an optical-axis direction is within the focus range. When an exposure time for one exposure does not reach an exposure time to obtain optimum exposure, a plurality of exposures are performed until a total exposure time reaches the exposure time to obtain the optimum exposure. When the plurality of exposures are performed, a plurality of obtained images are combined to generate an image with the optimum exposure. COPYRIGHT: (C)2008,JPO&INPIT |
