Vehicular vision system with head up display

A vehicular vision system includes a camera disposed at a vehicle having a field of view at least forward, rearward and/or exterior of the equipped vehicle. An image projection device is disposed in the vehicle and includes a biaxial microelectromechanical scanner and at least one light source operable to emit light. Light emitted by the at least one light source, when operated, is projected by the biaxial microelectromechanical scanner towards a windshield of the vehicle so as to form video images that are viewable by a driver of the vehicle viewing the windshield when driving the vehicle. The video images viewed by the driver viewing the windshield include video images derived from image data captured by the camera.
