The disclosed distance measuring device for a camera capable of measuring the distances of a plurality of objects within a target area comprises center-weighting means for treating the distance information of the object whose image lies near or at the center of the area of the picture frame with a heavier emphasis than those of the other objects, whereby an optimum focusing adjustment is allowed to be formed automatically.

A distance measuring device for a camera capable of measuring distances of a plurality of points in a photographic scene area by projecting distance measuring signals to the points and receiving the signals reflected from the points, comprising: (A) signal emitting means for projecting the distance measuring signals to the plurality of points in the scene area, said signal emitting means emitting a distance measuring signal of greater intensity to a central portion of the scene area than a distance measuring signal emitted by said signal emitting means to a marginal portion of the scene area, and said signal emitting means comprising: (A-1) first light emitting means for projecting the distance measuring signal to the central portion of the scene area; and (A-2) second light emitting means for projecting the distance measuring signal to the marginal portion of the scene area, the signal emitted from the second light emitting means being weaker than the signal emitted from the first light emitting means; and (B) signal receiving means for receiving the distance measuring signals reflected by the points in the scene area, said signal receiving means forming a proper distance measuring information based on distance measuring information of the plurality of points in the scene area obtained from the reflected signals, and intensified with respect to the central portion than the marginal portion of the scene area according to the degrees of intensity of the reflected signals, wherein the light emission intensity of the first light emitting means and the light emission intensity of the second light emitting means satisfy the following condition: [Figure]
