Title:
METHOD FOR CONTROLLING A LIGHT PATTERN AND AUTOMOTIVE LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/207578
Kind Code:
A1
Abstract:
The invention provides a method for controlling a light pattern (1) provided by an automotive lighting device (10) of an automotive vehicle (100). The method comprises the steps of 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 (11) and a second portion (12). Each portion (11, 12) comprises at least a boundary pixel (6, 8) which is in contact with the boundary pixel of an adjacent portion. Finally, the method includes modifying the width of the first portion (11) and the width of the second portion (12) by shifting the position of the boundary pixels (6, 8) 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 (11, 12), wherein the boundary pixels (6, 8) that were adjacent before the shifting remain adjacent after the shifting.
