The image of a subject is attained by image sensing and the image of the subject is displayed on the display screen of a digital still camera. The image of a face is detected from within the image of the subject and a face frame is displayed so as to enclose the detected image of the face. Autofocus control and automatic exposure control is carried out using image data representing the image within the face frame. Image data representing the image of the subject in which the image of the face is in focus and has the appropriate brightness can be recorded on a memory card.
