VEHICLE VISION SYSTEM WITH ENHANCED LOW LIGHT CAPABILITIES

摘要

A vision system of a vehicle includes a camera, a control and a display device. The camera is disposed at a vehicle and has a field of view exterior of the vehicle. The camera includes a two dimensional array of a plurality of photosensing elements. The control has an image processor operable to process image data captured by the camera. The display device is viewable by a driver of the vehicle and includes a video display screen. Responsive to a determination of a reduction in light level at the imaged scene, the control is operable to adjust at least one of (i) an exposure time for image capture by the camera and (ii) a frame rate of image capture by the camera. The control is operable to adjust the camera to control the display intensity of video images displayed by the video display screen.
