The invention relates to a method for controlling a motor vehicle headlight which at least comprises a laser diode () and a light conversion element () paired with the laser diode (). Light conversion element () regions corresponding to different regions of the light image (') can be illuminated periodically and with a varying intensity by means of a light beam () of the laser diode (), and the illumination intensity in the light conversion element () regions corresponding to the different regions of the light image (&#x2032;) is adjusted simultaneously by both the relative illumination duration of the different regions as well as different luminous intensities of the laser diode () in the light conversion element () regions corresponding to the different regions of the light image (&#x2032;). In regions in which the light beam () is moved with an angular speed below a defined value for the angular speed, the laser diode () is solely deactivated and activated, and different luminous intensities of the laser diode () are set when the angular speed is above a defined value. The motor vehicle headlight according to the invention has a computing unit () for carrying out the method according to the invention.
