Abstract:
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; a reticle substrate disposed between said video camera device and said lens for visually delineating an in-path portion of said field of view in which said in-path objects are displayed with a first light transmissivity from an out-of-path portion of said field of view in which said out-of-path objects are displayed with a second light transmissivity perceptibly different from the first light transmissivity, wherein said reticle substrate is optically transparent; and a reticle array formed on said reticle substrate such that the imaged and displayed field of view includes an image of said reticle array, said reticle being defined by such image of such reticle array, wherein said reticle array includes a conical or frustro-conical region of substantially un-attenuated light transmissivity corresponding to the in-path portion of the displayed field of view, and a region of perceptibly attenuated light transmissivity corresponding to the out-of-path portion of the displayed field of view.
