Abstract: A vision system for a vehicle includes a camera disposed at a vehicle and having a field of view exterior of the vehicle, an image processor operable to process image data captured by the camera, and a display operable to display images derived from image data captured by the camera. The image processor, via processing of image data captured by the camera, determines a noise level in image data captured by the camera. The vision system applies a lens shading algorithm to captured image data, and the vision system adjusts a level of the lens shading algorithm responsive to the determined noise level.

Abstract: A calibration system for a multi-camera vision system of a vehicle includes a plurality of calibration targets disposed at an area at which the vehicle is positioned for a calibrating procedure. The calibration targets may include a patterned array of markings, such as colored or black/white or shaded markings or dots, disposed at forward, rearward and/or sideward regions of the vehicle. The control is operable to process image data captured by the cameras and, responsive to processing of captured image data, the control is operable to determine a particular local pattern of markings of the respective calibration target to determine the position of the respective calibration target relative to the camera that is imaging that target. Responsive to processing of captured image data, the calibration system is operable to calibrate the multi-camera vision system of the vehicle.
