| Title: |
Emulating a Spotlight that is Partially Covered by a Mask |
| Abstract: |
A method and a device emulate a headlamp that is partially covered by a mask. In order to make it possible to implement a lighting design that is independent of any pre-settings in the headlamps using inexpensive and readily available lighting components while retaining existing lighting control protocols, a two-dimensional pattern is retrieved from a pattern memory in accordance with a pattern channel value of a lighting control protocol and is transformed in accordance with transformation channel values of the lighting control protocol. After transforming the two-dimensional patters, the resulting transformed pattern is converted into a raster image, the pattern pixels of which are brighter by at least 20% than the remaining pattern-free pixels. The raster image is output as a headlight using a digital projector. |
