Abstract: A camera auxiliary light system provides supplemental illumination for a passive ranging system in determining camera-to-object distance, provides a self-timer activation status light to persons in a scene, provides a point of visible light to assist in aiming the camera, and provides red-eye reduction illumination. Thus, multiple functions are performed by a single auxiliary light, thereby reducing the number of camera elements and reducing camera cost, size, and weight. The system includes an auxiliary light source, a mode control switch that selects between a self-timer mode, a red-eye reduction mode, and a flash defeat mode, a light sensor that receives light from the scene and produces a signal that indicates the relative amount of light that was received, and a light source controller that controls operation of the auxiliary light source in response to actuation of a shutter release of the camera.
