Abstract
A method for displaying video images via a vehicular vision system includes providing a rear backup camera having an imager and a wide angle lens disposed at the imager with its center axis vertically offset from a center region of an imaging array sensor of the imager. A distant central horizon region is imaged at the upper region of the imaging array sensor via light that has passed through a center region of the wide angle lens, and a closer region is imaged at the center region and the lower region of the imaging array sensor via light that has passed through a lower peripheral region of the wide angle lens. Video images derived from image data captured by the rear backup camera are displayed on a video display for viewing by a driver of the vehicle during a reversing maneuver of the vehicle.
