The method includes causing the HD headlight to reproduce an output video signal (2) provided by a headlight controller; providing an input video signal (1) to the headlight controller at an input image frequency; using the headlight controller for calculating the output video signal (2) in accordance with at least one image processing function in time within a predefined image processing frequency (4, 6); determining whether the headlight controller is burdened by a computing time expenditure required to perform the at least one image processing function within an available calculation time between two successive output video signals (2) at the predefined image processing frequency (4, 6), and varying the image processing frequency (4, 6) depending on a driving situation. A system also is provided to carry out the method.
VEHICLE PROJECTION LENS AND VEHICLE LAMP
A vehicle projection lens includes a plastic aspheric first lens, an aperture stop, a cemented lens consisting of a glass second lens and a glass third lens, and a glass fourth lens arranged in order from a magnified side to a minified side. An F-number of the vehicle projection lens is smaller than or equal to 0.8, and the vehicle projection lens consists essentially of four lenses respectively with positive, positive, negative and positive refractive powers.
VEHICLE HEADLAMP DEVICE
A vehicle headlamp device to be applied to a vehicle includes a light source, a lens, and a controller. The light source is configured to emit light. Light emitted from the light source is to pass through the lens. The controller is configured to control light distribution patterns for the light. The light distribution patterns include at least a first light distribution pattern and a second light distribution pattern. The first light distribution pattern illuminates an area ahead of the vehicle during running of the vehicle. The second light distribution pattern is projected as a marking at an optical axis adjustment that is performed during manufacturing of the vehicle. The controller causes a part of the light source to emit light so that the second light distribution pattern is formed.
