Beschreibung
Zusammenfassung:	A vehicular driver monitoring system includes a driver monitoring camera and an illumination source accommodated within a movable head of an interior rearview mirror assembly of a vehicle. The illumination source is electrically activatable to emit near-infrared (NIR) light that illuminates with near-infrared (NIR) light at least the eyes of a driver of the vehicle. Emission of near-infrared (NIR) light by the illumination source is modulated on/off at an illumination source modulation rate. The camera frame capture rate of the driver monitoring camera is bigger than the illumination source modulation rate of near-infrared (NIR) light emitted by the illumination source. Frames of image data are captured by the camera and are processed while the illumination source is on and is emitting near-infrared (NIR) light, and frames of image data are captured by the camera and are processed while the illumination source is off and is not emitting near-infrared (NIR) light.
