Method for managing image data, and vehicle lighting system

A motor vehicle lighting system comprising:

• at least one lighting module including a plurality of light sources able to project at least one photometry or lighting function from a compressed data list,
• a multiplexed bus for transmitting the compressed data list to the at least one lighting module, and
• a control unit configured to:
• receive an instruction to activate at least one image intended to be projected, with the at least one image being respectively defined by a matrix with a plurality of horizontal or vertical rows of pixel, with each pixel being characterized by a numerical value related to a light intensity of the pixel;
• calculate, for each pixel in each row in the matrix, a gradient value based on the numerical value of the pixel under analysis and on the numerical value of an adjacent pixel;
• determine, for each pixel in each row in the matrix, whether the pixel under analysis is a significant point of inflection of a curve relating to the row, based on the difference in intensity between the pixel under analysis and a compressed pixels from the compressed data list, and based on the spatial difference between the pixel under analysis and the compressed pixel and dynamically adapting the value relating to the difference in intensity between the pixel under analysis and the compressed pixel, along with the value relating to the spatial difference between the pixel under analysis and the compressed pixel based on the activation at least one photometry or lighting function;
• store the pixel under analysis in the compressed data list when the pixel under analysis is considered to be a significant point of inflection;
• and
• transmit the compressed data list to the at least one lighting module so that it is able to project a resulting image.
