Abstract
An automatic dimming vehicle mirror system includes an automatic dimming mirror assembly having automatic dimming circuitry. The automatic dimming circuitry includes a mirror control and at least a first silicon-based photo sensor and a second silicon-based photo sensor. The first silicon-based photo sensor is sensitive to both visible light and infrared light. The second silicon-based photo sensor is sensitive principally to infrared light. The mirror control distinguishes headlamp sources from non-headlamp sources by a ratio of a signal indicative of light detected by the first photo sensor to a signal indicative of light detected by the second photo sensor.
