Abstract: The invention relates to a method for managing image data in an motor vehicle lighting system, the lighting system including at least one lighting module intended to project light beams generated on the basis of data relating to the selection of at least one image. The method including receiving an instruction to activate at least one image to be projected, converting the original image into N grey levels, determining, for each pixel in each row in the matrix, whether the pixel under analysis is a significant point of inflection, storing the pixel under analysis as a compressed pixel in a list when the pixel under analysis is considered to be a significant point of inflection, and transmitting the list to the at least one lighting module so that it is able to project a resulting image.

Abstract: A method for controlling a lighting system for a motor vehicle having a system for detecting objects includes defining at least one set of detectable types of objects and acquiring, by means of the detection system, a set of data relating to the position of a plurality of objects of types belonging to the set. Also included is determining a lighting model which is associated with said set and defines at least one zone referred to as the initial detection zone, and a light pattern referred to as the initial light pattern, of a light beam intended to be emitted in the initial detection zone. The lighting system is controlled in order to emit a light beam having the initial light pattern in the initial detection zone of said lighting model.
