Abstract
A method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle. The method includes 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 and dividing each row group in at least a first portion and a second portion. Each portion includes at least a boundary pixel which is in contact with the boundary pixel of an adjacent portion. The method further includes 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.
