ZOOM CONTROL DEVICE, IMAGING APPARATUS, CONTROL METHOD OF ZOOM CONTROL DEVICE, AND RECORDING MEDIUM

摘要

A subject detection unit of an imaging apparatus detects a subject image from an image. An automatic zoom control unit designates the subject image detected by the subject detection unit and cancels the designation. The automatic zoom control unit automatically selects a specific composition among a plurality of compositions and sets a reference size of the subject image used to control a zoom magnification based on the elected composition. The automatic zoom control unit controls the zoom magnification based on the reference size and a size of the subject image sequentially detected by the subject detection unit. At least one of composition selection candidates selected by the automatic zoom control unit is different according to whether the subject image is designated by the automatic zoom control unit.
