The invention provides a method for controlling a light pattern (1) provided by an automotive lighting device (10) of a motor vehicle (100). The method comprises the following steps: providing a road contour; extracting road features from the road contour; dividing the matrix arrangement into row groups; assigning a different shift value to each row group, each shift value depending on road characteristics; and dividing each row group into at least a first portion (11) and a second portion (12). Each portion (11, 12) comprises at least a boundary pixel (6, 8) in contact with a boundary pixel of an adjacent portion. Finally, the method comprises 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 a corresponding shift value and interpolating the luminous intensity values of the pixels belonging to the first and second portions (11, 12), where the adjacent boundary pixels (6, 8) before the shift are not shifted and the adjacent boundary pixels (6, 8) are not shifted before the shift. 8) remains adjacent after the displacement.

    本发明提供一种用于控制由机动车辆(100)的汽车照明设备(10)提供的光图案(1)的方法。方法包括步骤:提供道路轮廓;从道路轮廓提取道路特征;将矩阵布置划分成行组;为每个行组分配不同的移位值,每个移位值取决于道路特征;以及将每个行组分成至少第一部分(11)和第二部分(12)。每个部分(11,12)至少包括与相邻部分的边界像素接触的边界像素(6,8)。最后,方法包括通过以下方式修改第一部分(11)的宽度和第二部分(12)的宽度:根据对应的移位值对每个行组中的边界像素(6,8)的位置进行移位,并对属于第一部分和第二部分(11,12)的像素的发光强度值进行插值,其中在移位之前相邻的边界像素(6,8)在移位之后保持相邻。
