A vehicle vision system includes a vehicle having first and second spatially separated image capture sensors. The first image capture device has a first field of view haying a first field of view portion at least partially overlapping a field of view portion of a second field of view of the second image capture device. A control receives a first image input from the first image capture sensor and a second image input from the second image capture sensor and generates a composite image synthesized from the first image input and the second image input. A display system displays the composite image.
