Abstract
A vehicular multi-camera vision system includes a plurality of cameras and a control having an image processor operable to process image data captured by the cameras. The control is operable to control a display intensity of video images displayed by a video display screen. Responsive to a determination of a reduction in exterior ambient light level within the field of view of at least one of the cameras, the control holds display intensity of video images displayed by the video display screen to within 15 percent of the display intensity that was displayed before the determination of the reduction in exterior ambient light level by (a) adjusting an exposure time for image data capture by at least some of the cameras and by (b) adjusting a frame rate of image data capture by at least one of the cameras and/or) adjusting a gain of at least one of the cameras.
