An auto focus system includes first and second detector arrays which receive first and second detection images of an object. The detection images are displaced from each other by a distance which depends upon the distance to a remote object. The detector arrays produce output signals which vary with the position of the detection images and thus with the distance to the object. The output signals are processed to provide a resultant signal indicative of the distance to the object and this signal may be used, for example, to control the position of a lens in a photographic camera.
