Vehicular vision system with rear backup video display
First Claim
1. A vehicular vision system, said vehicular vision system comprising:
- a rear backup camera disposed at a rear portion of a vehicle equipped with said vehicular vision system;
said rear backup camera having a field of view exterior and at least rearward of the equipped vehicle;
wherein the field of view of said rear backup camera is at least 130 degrees;
wherein said rear backup camera is electrically powered no later than 200 milliseconds after a driver of the equipped vehicle shifts a vehicle transmission of the equipped vehicle into reverse gear to commence a backup event;
wherein a valid video signal is available from said rear backup camera no later than 500 milliseconds after electricity is provided to said rear backup camera;
wherein said rear backup camera remains electrically powered throughout the backup event being executed by the driver of the equipped vehicle;
a display device comprising a video display screen disposed in an interior cabin of the equipped vehicle and viewable by the driver of the equipped vehicle, said video display screen having a diagonal dimension of at least 5 inches;
wherein said vehicular vision system displays on said video display screen stable rear backup video images derived from image data captured by said rear backup camera no later than 2 seconds after the driver of the equipped vehicle shifts the vehicle transmission into reverse gear; and
wherein, commencing when the vehicle transmission of the equipped vehicle was shifted into reverse gear to begin the backup event, only rear backup video images derived from image data captured by said rear backup camera are displayed on said video display screen for the duration of the backup event.

Abstract
A vehicular vision system includes a rear backup camera and a display device including a video display screen. The rear backup camera is electrically powered no later than 200 milliseconds after a driver of the vehicle shifts the vehicle transmission into reverse gear to commence a backup event. A valid video signal is available from the rear backup camera no later than 500 milliseconds after electricity is provided to the camera. The vehicular vision system displays on the video display screen stable rear backup video images derived from captured image data no later than two seconds after the driver shifts the vehicle transmission into reverse gear. Commencing when the vehicle transmission was shifted into reverse gear to begin the backup event, only rear backup video images derived from image data captured by the rear backup camera are displayed on the video display screen for the duration of the backup event.
