Patent attributes
A vehicular interior rearview mirror assembly includes a mirror head accommodating an interior rearview mirror reflective element. The mirror reflective element has a mirror transflector that transmits near infrared light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. The mirror transflector includes repeating alternating layers of a higher refractive index layer and a lower refractive index layer. A megapixel camera is disposed within the mirror head behind the mirror reflective element and views through the mirror transflector. A near infrared illumination source is disposed within the mirror head and operable to emit near infrared light that passes through the mirror transflector. Responsive at least in part to the data processor processing captured image data, at least one selected from the group consisting of (i) driver attentiveness is monitored, (ii) driver drowsiness is monitored and (iii) driver gaze direction is monitored.
