A method of image enhancement for a vehicle vision system includes capturing multiple frames of image data with a camera and executing a first brightness transfer function on a current frame of captured image data to generate a first enhanced image frame. At least one previously captured frame of image data is retrieved, and a second brightness transfer function is executed on the at least one previously captured frame of image data to generate a second enhanced image frame. The first and second enhanced image frames are blended to generate a blended enhanced image frame, and these steps are repeated so as to generate multiple blended enhanced image frames. The presence of an object is detected via processing of blended enhanced image frames by a processor, and an output is generated responsive to detection of the object.
