Abstract

A vehicular display system includes a single video display screen and a video processor operable to process captured video image data captured by a camera at the vehicle. The single 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 between the left and right display regions. The display screen is operable to use each display region to display video images derived from a respective portion of captured image data. When the 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 single video display screen does not display video images representative of the other portion of captured image data at the other display region.
