Abstract
A vehicular vision system includes first, second, third and fourth cameras having respective forward, rearward, sideward and sideward fields of view. A video processor is operable to process second image data captured by the second or rearward viewing camera. A video display screen displays video images derived, at least in part, from captured second image data. The video processor includes an image processor operable for machine vision analysis of first image data captured by the first or forward viewing camera. During a reversing maneuver of the vehicle, the video display screen displays video images derived, at least in part, from captured second image data. During forward travel of the vehicle and responsive to the image processor processing captured first image data to detect a road sign ahead of the vehicle, an image or iconistic representation of the detected road sign is displayed by the video display screen.
