An object is to cause a distribution of defocus amounts in a certain arbitrary region of a captured image to be displayed. A map data generation unit configured to generate defocus map data representing defocus amounts at a plurality of positions in a captured image obtained by an imaging element unit, calculated from phase difference information detected by a phase difference detection unit, and a display control unit configured to generate a defocus map image representing a distribution of defocus amounts of the captured image using the defocus map data generated by the map data generation unit and to perform display control are included.

A focus driving control unitof a control unitperforms 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 unitperforms 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.

Focus control device, focus control method, program, and imaging device

A focus driving control unitof a control unitsets 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 unitsets 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. In a case in which the imaging mode is a mode in which a stationary subject is imaged or a case in which a subject is detected to be a stationary subject, the subject priority ranging size is set to the ranging size at the time of the speed priority driving or to be less than the ranging size at the time of the speed priority driving. Therefore, it is possible to easily perform stable focus control.
