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.
