ABSTRACT:
An automatic focusing camera includes a first distance measurement circuit for measuring a first distance to an object located at a central portion of a frame, a second distance measurement circuit for measuring a plurality of second distances to other objects located at a peripheral portion of the frame, a CPU for comparing the first and second distance with a shortest photographing distance of the camera, for, when the first distance is shorter than the shortest photographing distance, selecting the shortest photographing distance as an object distance regardless of the second distance, for, when the first distance is not shorter than the shortest photographing distance and the second distance is shorter than the shortest photographing distance, selecting the first distance as the object distance, and for, when the first and second distances are not shorter than the shortest photographing distance, selecting a shorter one of the first and second distances as the object distance, and a mechanism for focusing a photographing lens on the basis of the object distance selected by the CPU.
