摘要
A vision system for a vehicle includes an imaging sensor disposed at the vehicle and having an exterior field of view, and an image processor. The imaging sensor captures image data and the image processor is operable to process successive frames of captured image data. Responsive to a determination of a low visibility driving condition, the image processor increases the contrast of the captured images to enhance discrimination of objects in the field of view of the imaging sensor. The image processor may execute a first brightness transfer function on frames of captured image data to enhance the contrast of captured image data, and may execute a second brightness transfer function over successive frames of earlier captured image data and may execute a tone mapping of the earlier captured image data and the currently captured image data to generate a contrast enhanced output image.
