Abstract

A vehicular vision system includes a video display screen and a video processor operable to process captured video image data captured by a rearward-viewing camera at the vehicle. The video display screen includes a left display region at a left portion, a right display region at a right portion, and a middle display region that spans between the left and right display regions. The video display screen is operable to use the left and right display regions to display video images derived from a respective portion of captured image data. When the video display screen is displaying video images at the right or left display region that are derived from the respective portion of captured image data, the video display screen does not display video images representative of the other portion of captured image data at the other display regions.
