Abstract

A display system of a vehicle includes a camera disposed at a vehicle and having a field of view interior of the vehicle that encompasses a head region of a driver of the vehicle. An image processor is operable to process image data captured by the camera to determine a location of both eyes of the driver of the vehicle. A display device is operable to display or project a first image and a second image for viewing by the driver of the vehicle. A first reflector element that is adjusted, responsive to image processing by the image processor of image data captured by the camera, to reflect the first and second images so that a left eye of the driver views the reflected first image and a right eye of the driver views the reflected second image.
