Beschreibung
Zusammenfassung:	The present invention concerns a method for controlling a laser-based lighting system comprising a scanning mirror arrangement, arranged to be rotatable around two substantially orthogonal axes. The method comprises: (a) a sensor capturing a first image; (b) the sensor sending data representing at least part of the first image to an image generation unit; (c) the image generation unit generating a second image based on the data representing at least part of the first image, wherein the generated second image comprises information representing a feature region in the first image; (d) the image generation unit sending the second image to a projection system controller; and (e) the projection system controller, based on the received second image, controlling the operation of a projection system comprising a laser light source; and a scanning mirror arrangement for receiving the light radiated by the laser light source, and for reflecting the received light to a wavelength conversion element to project the second image. In the method the second image is streamed to the projection controller as an image pixel stream without first saving it in a memory.
