摘要： A distance-measuring apparatus comprises a first detecting device for detecting a distance to a central portion of an object field corresponding to a photographing frame and generating data corresponding to a detected distance, a second detecting device for detecting distances to a plurality of peripheral portions of the object field except for the central portion and generating data corresponding to detected distances, and an operating device for operating the first and second detecting devices. The oeprating device has a first operation step of operating the first detecting device and a second operation step of operating the second detecting device. The first step is executed to determine the detected distance to the central portion. The execution of the second step depends on the determination result and may produce an average peripheral distance output or a shortest peripheral distance output for driving a phototaking lens. Depending upon the determination result, a central distance output may instead by produced.
