Abstract
A wide-angle image capture system for providing a wide-angle field of view of an area immediately exteriorly of a vehicle. The system includes a convex aspheric, asymmetric reflective surface which reflects an image toward an image capture device, via a substantially flat mirrored surface, both of which are compactly packaged within a panel of the vehicle. The shape of the convex reflector provides a reflected image that has a minimal amount of distortion in critical areas of the image immediately adjacent to the vehicle, so that additional processing of the image prior to it being displayed to a vehicle operator is minimized.
