Abstract
A vehicle vision system includes a bracket, a stray light shield and a camera module. The bracket is configured to attach at an in-cabin surface of a vehicle windshield. The light shield includes a base portion and side walls that extend upward from the base portion so as to establish a pocket. The camera module includes a camera having an image sensor array and a lens, and the camera module is configured to mount at the bracket. The stray light shield, when the camera module is mounted at the bracket attached at the windshield, shields the image sensor array from light emanating from within the cabin of the vehicle. At least the base portion of the stray light shield comprises light traps structurally established thereat and configured to reduce incidence of extraneous light at the image sensor array.
