    Abstract: A method for determining a safe state for a vehicle includes disposing a camera at a vehicle and disposing an electronic control unit (ECU) at the vehicle. Image data is captured via the camera and provided to the ECU. An image processor of the ECU processes captured image data. A condition is determined via processing at the image processor of the ECU captured image data. The condition comprises a shadow present in the field of view of the camera within ten frames of captured image data or a damaged condition of the imager within two minutes of operation of the camera. The condition is indicative of a condition where processing of captured image data degrades in performance. The ECU determines a safe state for the vehicle responsive to determining the condition.

    Abstract: A vision system for a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. A processor is operable to process image data captured by the camera. The vision system determines conditions where processing of captured image data degrades in performance due to environmental conditions. The vision system, responsive to a determined condition, determines a safe state for image processing of captured image data for that determined condition. A failsafe algorithm, responsive to processing of image data captured by the camera and responsive to the determined condition, and in accordance with the determined safe state for that determined condition, determines true negatives and avoids false positives and false negatives.

    Abstract: A method of calibrating a vehicular camera installed in a vehicle, with the camera having an imager and a camera microcontroller, includes searching for and/or determining a reference point in the images and adjusting the position of an overlay applied to displayed images depending on the reference point. The method may include comparing the determined reference point's actual position to its expected position and determining an offset amount with which to shift the overlay on the images displayed at an in-vehicle display responsive to the determined offset amount, and adjusting the position of the overlay applied to the images displayed at the in-vehicle display responsive to the determined offset amount.
