Claim 3:
4. The method according to claim 2, wherein the light sources of the headlamp are divided into a number of rows and columns, wherein the pixels of the source symbol are divided into the same number of rows and columns so that a column and a row of the pixels correspond to each row and column of the light sources, wherein, for both the light sources when using the first luminous intensities and the light sources when using the second luminous intensities and for the pixels, a number of boundaries is determined for each row and each column, wherein a boundary is determined when a difference in brightness between two adjacent light sources or two adjacent pixels is greater than a threshold value, wherein, when using the first luminous intensities, the first indicator is equal to the number of boundaries in the column or row of light sources which has the greatest difference to the number of boundaries in the corresponding column or row of pixels, wherein the second indicator is equal to the number of boundaries in the corresponding column or row of light sources when using the second luminous intensities, and wherein the third indicator is equal to the number of boundaries in the corresponding column or row of pixels.
