Abstract
A camera including a photoelectric diode operated as an emitter in a first mode and a sensor in a second mode. The camera includes a first circuit that operates the diode to emit visible radiation and a second circuit that operates the diode to sense scene illumination. The diode is switched between the respective circuits selectively to operate in its first and second modes. The first circuit preferably is a timing circuit in a self-timing camera, but also might provide other functions including reduction of red-eye effects. The second circuit preferably is a photometer for controlling exposure.
