Vehicular interior rearview mirror assembly with driver monitoring camera

A vehicular interior rearview mirror assembly, the vehicular interior rearview mirror assembly comprising:

• a mirror head adjustable relative to a mounting base, the mounting base configured to mount the vehicular interior rearview mirror assembly at an interior portion of a vehicle;
• wherein the mirror head comprises a mirror reflective element;
• wherein the mirror reflective element comprises a glass substrate, and wherein the glass substrate has a first side and a second side opposite the first side and spaced from the first side by a thickness of the glass substrate, and wherein a mirror reflector is disposed at the second side of the glass substrate, and wherein, with the vehicular interior rearview mirror assembly mounted at the interior portion of the vehicle, the first side of the glass substrate is closer to a driver of the vehicle than the second side of the glass substrate;
• a driver monitoring camera accommodated by the mirror head, wherein the driver monitoring camera moves in tandem with the mirror head when, with the vehicular interior rearview mirror assembly mounted at the interior portion of the vehicle, the mirror head is adjusted relative to the mounting base to adjust a rearward view of the driver viewing the mirror reflective element;
• a near infrared light emitter accommodated by the mirror head, wherein the near infrared light emitter moves in tandem with the mirror head;
• wherein the driver monitoring camera comprises an imager and a lens;
• wherein the driver monitoring camera views through a camera-region of the glass substrate of the mirror reflective element;
• wherein, the second side of the glass substrate is not parallel to the first side of the glass substrate at least at the camera-region of the glass substrate;
• a refraction-compensating element disposed between the lens of the driver monitoring camera and the camera-region of the glass substrate of the mirror reflective element;
• wherein the refraction-compensating element has a first side and a second side opposite the first side and spaced from the first side by a thickness of the refraction-compensating element, and wherein the second side of the refraction-compensating element is not parallel to the first side of the refraction-compensating element;
• wherein the refraction-compensating element offsets refraction of light that passes through the camera-region of the glass substrate of the mirror reflective element;
• and
• wherein, with the vehicular interior rearview mirror assembly mounted at the interior portion of the vehicle, a processor processes image data captured by the driver monitoring camera to determine at least one selected from the group consisting of (i) driver attentiveness, (ii) driver drowsiness, and (iii) driver gaze direction.
