An optical electronic device such as a photographic camera having an objective optical system for forming two images of the same object laterally offset with respect to each other, and a photoelectric receiving device receiving the offset signals. The photoelectric receiving device includes a pair of individual photoelectric receivers upon each of which one of the images of the object is incident. The individual receivers have approximately equal receiving areas which uniformly increase laterally from one side to the other and each receiver provides electrical output signals to an electronic difference circuit.
