Abstract
A vehicular vision system includes at least a first image capture sensor and a second image capture sensor disposed at a vehicle and spatially separated and having respective fields of view with respect to the direction of travel of the equipped vehicle. A control receives a first image input from the first image capture sensor and a second image input from the second image capture sensor and generates a composite image synthesized from at least the first image input and the second image input. A display system displays the composite image on a single video screen located in a cabin of the equipped vehicle and viewable by a driver of the equipped vehicle when the driver is normally operating the equipped vehicle. The single video screen of the display system may have a display luminance that is variable responsive to a sensing of an ambient light level.
