Patent attributes
A vehicular driver monitoring system includes a camera disposed within and viewing within an interior cabin of a vehicle. The camera includes a lens and an image sensor. The camera is operable to capture image data. Electronic circuitry of an electronic control unit (ECU) includes an image processor for processing image data captured by the camera. With a driver of the vehicle sitting in a driver seat of the vehicle, light is reflected off a portion of the driver to impinge at the lens of the camera. The vehicular driver monitoring system, via processing at the ECU of image data captured by the camera, determines a deficiency in captured image data arising from light impinging at the lens. The determined deficiency in captured image data arises from an occlusion at the lens of the camera.
