First Claim
1. Apparatus for displaying a video image of a scene in a travel path of a vehicle, comprising:
- a video camera device and lens for imaging a field of view including said travel path, said field of view including out-of-path objects that are out of said travel path as well as in-path objects that are in said travel path;
a video display device for displaying the imaged field of view; and
means for providing a reticle on said video display device for visually delineating an in-path portion of said field of view in which said in-path objects are displayed from an out-of-path portion of said field of view in which said out-of-path objects are displayed.

Abstract
A vehicle vision system displays a vehicle pathway image that includes a reticle for visually identifying the in-path portion of the image. A reticle array is disposed between a video camera chip and a lens, and includes a conical or frustro-conical region of substantially un-attenuated light transmissivity surrounded by a region of perceptibly attenuated light transmissivity, such that in-path portions of the displayed image are substantially unchanged and out-of-path portions of the displayed image are perceptibly attenuated. The reticle array may also include a number of reduced transmissivity lines traversing its conical or frustro-conical region to produce a series of receding stadia lines in the in-path portion of the displayed image, enabling the driver to reliably discern the range of displayed objects.
