In the case where the first judging section judges that the photography scene is not the night scene, a second judging section judges whether or not the scene to be photographed is the reverse light scene. A main object specifying section specifies the main object in the case where either the first judging section or the second judging section judges the scene to be photographed is either the night scene or the reverse light scene.
