Abstract: A focus driving control unit 34 of a control unit 30 performs speed priority driving control in which a focus lens is driven to a focusing position in a driving pattern selected in advance by a user, for example, in a case in which a defocus amount of a ranging area is greater than a driving control determination threshold set in advance. In addition, the focus driving control unit 34 performs subject priority driving control in which a focus lens movement amount by which the focus lens is located at the focusing position in accordance with the defocus amount of the ranging area is set and the focus lens is driven in a case in which the defocus amount is equal to or less than the driving control determination threshold. The focus lens is driven to the focusing position in the driving pattern selected by the user. Thereafter, a focusing state can be maintained. Accordingly, it is possible to easily perform an auto-focus operation with the high degree of freedom.

Abstract: A focus driving control unit 34 of a control unit 30 sets a ranging area to a ranging size at the time of a speed priority driving which is a region size set in advance, for example, in a case in which a defocus amount of a ranging area is greater than a ranging area determination threshold set in advance. In a case in which the defocus amount is equal to or less than the ranging area determination threshold, the focus driving control unit 34 sets the ranging area to a subject priority ranging size which is a region size different form the ranging size at the time of the speed priority driving. For example, in a case in which an imaging mode is a mode in which a moving subject is imaged or a case in which a subject is a moving subject, the subject priority ranging size is set to be greater than the ranging size at the time of the speed priority driving.
