摘要 <P>PROBLEM TO BE SOLVED: To solve the problem that manual focusing has been used in many cases in the case of a high photographic magnification because it is difficult for an AF sensor of a camera to easily focus the camera on a user-desired focus target position due to an influence of competition between near and far subjects or the like, though it is suggested with respect to conventional defocusing correction means that auto-focusing is used during aiming and focus group correction based on acceleration sensor information is used after mirror up because an AF sensor for a retardation or the like is unavailable. Ž<P>SOLUTION: The user focuses the camera on a focus target position by manual focusing, and then defocusing correction based on acceleration sensor information is performed.
