Abstract
A controller sets a plurality of detection regions within an imaging area. The controller then compares a difference in a contrast signal level between a maximum contrast signal level and a minimum contrast signal level calculated from among contrast signal levels of contrast signals generated for the plurality of detection regions with a level difference threshold. The controller then sets a priority level in subject information concerning a subject on the basis of a comparison result. The controller then stores the subject information in a storage unit in accordance with the priority level set in the subject information. The controller then drives a focus lens on the basis of the subject information read from the storage unit so as to bring the focus lens into focus.
