Abstract
A camera having an electronic image pickup element and a distance-measuring circuit that uses light signals obtained from light images of a plurality of distance-measuring areas set in a photographing screen to select a main subject and measure the distance to the subject. The camera has a focusing component, operating when the position of the main subject cannot be identified by the distance-measuring circuit, to divide the photographing screen into a plurality of areas to identify an area in which the main subject is present on the basis of a luminance distribution obtained from the areas other than those overlapping the distance-measuring areas. The focusing component focuses a photographing lens on the position of the highest contrast signal while scanning the lens position of the photographing lens.
