With a digital still camera, a user freely detects a smiling face on a touchpanel displaying a through image and selects a subject having that smiling face. The digital still camera displays the smiling face as a smiling face detection target and a non-target detected face on the through image in a distinctly different manner to discriminate the smiling face detection target from the non-target detected face. For example, when persons in an event such as a party are photographed in a relatively large viewing angle, an auto photographing operation may be performed in response to smiling face detections on condition that at least two members in the party are smiling.
