Abstract
A vision system for a vehicle includes a camera disposed at a windshield of a vehicle and having a field of view forward of the vehicle and through the windshield of the vehicle. A processor is operable to process image data captured by the camera. An angular filter is disposed at or near the windshield forward of the camera. The angular filter includes a substantially transparent film that limits reflection of light through an angular range that generally corresponds to the stray light that reflects off of the vehicle dashboard and would otherwise impinge a lens aperture of the camera.
