Abstract

A distance-information acquisition unit acquires information about a distance to a subject in each focus detection region by setting a plurality of focus detection regions in an imaging region. A depth-of-field calculating unit calculates the depth of field for one major subject (principal object) on the basis of the information about a distance to the major subject, which is selected from a plurality of subjects, and a diaphragm value, which is corrected on the basis of optical characteristics of an APD filter. An insertion/retreat control unit determines whether or not a subject other than the major subject is present outside the depth of field on the basis of the information about the distance and inserts the APD filter onto the light path in a case in which the subject other than the major subject is present outside the depth of field.
