Abstract

A method is provided for calculating illumination setting values for light sources of a headlamp from a light distribution that is to be set. First, the light distribution that is to be set is read in. Then, the illuminance target values for pixels of an illumination area are calculated from the light distribution that is to be set, which are to be achieved by setting the light sources of the headlamp in order to set the read-in light distribution. Finally, the illuminance setting values for the light sources are calculated from the target values. Further, at least one illuminance setting value to which this light source is set is calculated iteratively for each light source of the headlamp.
