ABSTRACT:
A camera has a contrast detection section which detects contrast of an object image signal obtained through a taking lens, and a multipoint distance measuring section which ranges a plurality of points in a photographic screen through a pair of optical systems different from the taking lens. A first focus adjustment section focuses the taking lens in accordance with a detection result of the contrast detection section, and a second focus adjustment section focuses the same based on a distance measuring result of the multipoint distance measuring section. A position determination section determines a position of a main object in the photographing screen from the distance measuring result, and when it determines that the main object is positioned on a center, the first focus adjustment section is operated by a selection section, and when the main object is positioned on a periphery, the second focus adjustment section is operated.
