A digital camera automatically changes its imaging sensitivity based on a proper exposure value that is calculated at a predetermined standard imaging sensitivity based on subject brightness measured from a photometry area of a scene to shoot. When the decided imaging sensitivity is higher than a predetermined sensitivity threshold value, the scene is judged to be a low brightness backlit scene that contains a higher brightness portion around a dark main subject, and a lower brightness portion around the higher brightness portion.
