Abstract
A vision system of a vehicle includes a camera and a control. The camera is disposed in the vehicle and has a field of view encompassing a portion of a windshield of the vehicle. The control includes an image processor operable to process image data captured by the camera. The control, responsive to processing of captured image data by the image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction via reflection at the windshield of the vehicle. The vision system may include an illumination source that emits illumination towards the windshield to enhance determination of the driver'"'"'s head and eyes and gaze direction. The control, responsive to processing of captured image data by the image processor, may be operable to determine precipitation at the windshield.

12. A vision system of a vehicle, said vision system comprising:
-
a camera disposed in a vehicle and having a field of view encompassing a portion of a windshield of the vehicle; wherein an optical path between said camera and the driver'"'"'s eyes has a generally vertical portion between said camera and the portion of the windshield and a generally horizontal portion between the portion of the windshield and the driver'"'"'s eyes; a control having an image processor operable to process image data captured by said camera; an illumination source that, when activated, emits illumination towards the portion of the windshield; wherein said camera is operable to capture image data at least when said illumination source is activated; and wherein said control, responsive to processing of captured image data by said image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction via reflection of the driver'"'"'s head and eyes off a surface of the windshield of the vehicle. - View Dependent Claims (13, 14, 15, 16, 17)

18. A vision system of a vehicle, said vision system comprising:
-
a camera disposed in a vehicle and having a field of view encompassing a portion of a windshield of the vehicle; a control having an image processor operable to process image data captured by said camera; an illumination source that, when activated, emits illumination towards the portion of the windshield, wherein said illumination source comprises an infrared light emitting illumination source; wherein said camera is operable to capture image data at least when said illumination source is activated; wherein said control, responsive to processing of captured image data by said image processor, is operable to determine a driver'"'"'s head and eyes and gaze direction via reflection of the driver'"'"'s head and eyes off a surface of the windshield of the vehicle; and wherein said control, responsive to processing of captured image data by said image processor, is operable to determine precipitation at an outer surface of the windshield. - View Dependent Claims (19, 20)
