摘要： The invention relates to a motor vehicle headlamp (100) containing an ellipsoid reflector (130), which allows light coupled in from a light source (100) to exit through a reflector light exit opening (132), a collimator (140) and a projection optical unit (160). The collimator (140) is designed to collimate the incident light beam coming from the ellipsoid reflector (130) and to direct the same toward a first image plane (170). The projection optical unit (160) projects a light image produced by the light beam in the emission direction of the motor vehicle headlamp (100) in accordance with a second image plane (180) of the projection optical unit (160). The first image plane (170) and the second image plane (180) intersect or overlap with one another. In the beam path of the light beam, an optical element (150) having at least one optically active edge (151) is arranged between the collimator (140) and the projection optical unit (160) in such a way that the first and/or second image plane (170, 180) runs through the optical element (150), in order to mask a part of the light beam and to guide another part to the projection optical unit (160).

摘要： A vehicular vision system includes a camera disposed at a vehicle and having a field of view rearward of the vehicle, a light source disposed at the vehicle and operable to emit light, and a control including an image processor. The control, responsive to detection of the object present in the field of view of the camera, determines a region of the field of view of the camera at which a detected object is located. The control determines an illumination level at the detected object and, responsive to the determined illumination level at the detected object being greater than an upper threshold level or less than a lower threshold level, controls the respective individually controllable light segment of the light source for that region of the field of view of the camera at which the detected object is located to adjust intensity of light emitted by that light segment.
