1. A method for managing image data in an automotive lighting device, the method comprising the steps of:
providing an image pattern comprising a plurality of pixels, wherein each pixel is characterized by a numeric value related to a luminous intensity of the pixel;
dividing the image pattern in rows or columns of pixels, thus creating a plurality of row patterns;
providing, for each row pattern, a plurality of linear segments, each linear segment providing a linear approximation to a group of pixels based on the luminous intensity of each pixel;
characterizing each linear segment by two values;
compressing the values of the linear segments; and
sending the compressed data to a light module of the automotive lighting device.
