1. A method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle, wherein the light pattern is provided by a matrix arrangement of light pixels, the method comprising:
providing a road profile;
extracting road features from the road profile,
dividing the matrix arrangement in row groups;
assigning a different shifting value for each row group, each shifting value depending on the road features;
dividing each row group in at least a first portion and a second portion, wherein each portion includes at least a boundary pixel which is in contact with the boundary pixel of an adjacent portion;
modifying the width of the first portion and the width of the second portion by shifting the position of the boundary pixels in each row group according to the corresponding shifting value and interpolating the luminous intensity values of the pixels belonging to the first and second portion, wherein the boundary pixels that were adjacent before the shifting remain adjacent after the shifting.
