PURPOSE:To surely perform autofocusing when the change of a distance and the amount of the movement of an object are not constant in the case of performing autofocusing. CONSTITUTION:A control circuit 21 allows to act based on the inclination of the change and the degree of the reliability of a focusing evaluated value obtained from a counting circuit 23 and a focusing variation calculated by an LSC circuit 22, so that stable autofocusing is performed. |
