PROBLEM TO BE SOLVED: To carry out autofocus control for an object in various kinds of luminance areas, when a plurality of pictures obtained by photographing one object on a plurality of exposure conditions are composited and an image of a wide dynamic range is generated. SOLUTION: The autofocus control for the various kinds of objects currently photographed with a proper signal level in each image photographed on different exposure conditions can be carried out by providing a focusing voltage selection means to selectively output a plurality of focusing voltages detected from a plurality of images whose exposure conditions are different as a focusing voltage to be referred to by the autofocus control means. Furthermore, a means to normalize a plurality of focusing voltages is provided for the imaging unit, and the autofocus control which does not depend on exposure conditions by removing an influence on the focusing voltage given by the change of exposure conditions can be carried out. |
