Abstract

A vehicular interior rearview mirror system includes an interior rearview mirror assembly having one of (a) a variable reflectance reflective element and (b) a prismatic reflective element. The interior rearview mirror assembly includes an information display disposed behind and viewable through the reflective element. The interior rearview mirror assembly includes a video camera having, when the interior rearview mirror assembly is normally mounted in the vehicle, a field of view that encompasses one of (i) the windshield of the vehicle and (ii) the driver of the vehicle. The interior rearview mirror assembly may include other electrical accessories such as, for example, a light, a rolling code garage door opener, and a microphone.
