1. A method for controlling a headlight controller (23) and an HD headlight controlled by the headlight controller (23), the method comprising:
using at least one sensor of the vehicle for providing input video signals (1) to the headlight controller (23) at a predetermined initial input image processing frequency (4);
causing the headlight controller (23) to perform image processing that uses at least the input video signal (1) and calculates an output video signal (2) in a time defined by the image processing frequency (4);
causing the HD headlight to reproduce the output video signal (2) provided by the headlight controller (23) and to output illumination defined by the output video signal (2);
determining a computing time expenditure required to perform the image processing and to calculate the output video signal (2) in view of an existing driving situation or an existing traffic situation determined by the at least one vehicle sensor (22); and
varying the initial predetermined image processing frequency (4) to a new image processing frequency (6) if the computing time expenditure is determined to be inconsistent with the initial predetermined image processing frequency (4) due to the existing driving situation or the existing traffic situation determined by the at least one vehicle sensor (22).
