ABSTRACT:
A vehicle rearview mirror system includes a rearview mirror assembly comprising an electro-optic reflective element and, preferably, at least a first and a second photo-sensor, both facing generally in a common direction. A light piping element pipes light to the first photo-sensor from a light environment different from the light environment to which the second photo-sensor is exposed. The first photo-sensor may comprise a semiconductor photo-sensor sensitive both to visible light and to infrared radiation. A spectral filter may be disposed in front of the first photo-sensor to reduce the amount of infrared radiation incident thereat. One of the first and second photo-sensors may have a rearward field of view relative to the forward direction of travel of the vehicle, and the other of the first and second photo-sensors may have a forward field of view relative to the forward direction of the travel of the vehicle.
