A method of image enhancement for a vehicle vision system includes providing a camera at the vehicle and providing a processor operable to process image data. Multiple frames of image data are captured with the camera, and contrast is enhanced in image data by tone mapping. As the vehicle moves, contrast thresholds are tracked within the captured frames of image data with respect to image flow caused by the vehicle's movement. Image data of a first frame of captured image data may be passed through two individual image transfer functions to generate a first transferred frame of image data. The first transferred frame may be blended with a second frame of image data. Presence of an object is detected in the field of view of the camera, and an output is generated responsive to detection of the object present in the field of view of the camera.
