1. A method for determining a safe state for a vehicle, the method comprising:
disposing a camera at a vehicle such that the camera has a field of view exterior of the vehicle, the camera comprising a lens and an imager;
disposing an electronic control unit (ECU) at the vehicle, wherein the ECU comprises an image processor operable to process image data captured by the camera;
capturing image data via the camera and providing captured image data to the ECU;
processing at the image processor of the ECU image data captured by the camera and provided to the ECU;
determining, via processing at the image processor of the ECU image data captured by the camera and provided to the ECU, a shadow present in the field of view of the camera within ten frames of captured image data, wherein the determined shadow present in the field of view of the camera within ten frames of captured image data is indicative of a condition where processing of captured image data degrades in performance; and
determining, via the ECU, and responsive to determining the shadow present in the field of view of the camera within ten frames of captured image data, a safe state for the vehicle.
