An imaging device, an autofocus unit, a focusing-target registration unit, focusing-target specification unit and an authentication unit are provided. The autofocus unit performs focus adjustment of an optical system so that a subject within a certain AF area is in focus. The focusing-target registration unit registers, as information for specifying subjects to be set to a focusing target, character information and image information of the subjects. The focusing-target specification unit specifies a subject, which is a focusing target during taking, from among the registered subjects to be set to the focusing target. The authentication unit determines as to whether or not the subject being taken matches with the specified subject, which is the focusing target. If the authentication unit determines that the subject being taken matches with the specified subject, which is the focusing target, the autofocus unit performs the focus adjustment for the subject being taken.
