An image is obtained using a photographing unit including an optical system provided with an aperture and focus adjusting mechanism. Two or more types of subjects are detected from the image. When the two or more types of subjects are detected from the image, one priority subject is determined among the two or more types of subjects. The aperture and the optical system are adjusted so that the priority subject is focused and the subject other than the priority subject is within a depth of field of the photographing unit.
