A camera detects a face portion of a subject from a shot image to determine whether a shot image is a good shot candidate image from the features of the face portion and a face portion-related image portion. As examples, the features include, but not be limited to, (1) the shape and variation in contour ranging from the vicinity of the face portion, (2) the position of a hand or leg to be determined by similarity to the skin tone of the face portion, and (3) determination made from the detection result of the face portion as to whether the subject is a half-length or full-length figure.
