Abstract
A vehicular interior rearview mirror system includes an interior rearview mirror assembly, which includes an ambient light sensor operable to sense ambient light and a glare light sensor operable to sense glare light. A control is operable to establish a reflectance level of a transflective electrochromic reflective element of the mirror assembly and is responsive to light detection by the ambient light sensor and/or the glare light sensor. A backlit video screen is disposed behind the reflective element and is operable to display information through the mirror reflector of the reflective element. A display intensity control adjusts display intensity responsive to a light detection by the glare light sensor and/or the ambient light sensor and as a function of a ratio of a glare light value sensed by the glare light sensor to an ambient light value sensed by the ambient light sensor.
