Abstract
An operating method for a laser projection unit includes providing a data set representing a sequence of images or partial images to be projected and formed from image elements; before the projection, examining the data set with respect to a brightness of the image elements, determining a maximum brightness from the image elements, and determining a relative brightness of the image elements relative to the determined maximum brightness; and projecting the images or partial images of the data stream or part of the data stream by activating laser light sources of an illumination unit according to the relative brightnesses such that the brightness of a laser light source for an image element to be projected having a maximum relative brightness corresponds to a predetermined maximum absolute brightness, or lies in a safety interval below the predetermined maximum absolute brightness.
