摘要:
A method for correcting a light pattern provided by an automotive lighting device, wherein the light pattern is provided at least by a matrix arrangement of light sources. The method includes a first step of projecting a high beam pattern with a first zone where luminous intensity is lower, the first zone having a rectangular edge with four sides. The second step includes providing a number of pixels for each of the four sides of the edge of the first zone, thus creating an upper blur zone, a lower blur zone, a left blur zone and a right blur zone. A final step includes creating a blur pattern for the upper blur zone which extends along columns, a blur pattern for the lower blur zone which extends along columns, a blur pattern for the left blur zone which extends along rows and a blur pattern for the right blur zone which extend along rows, where the luminous intensity in each row or column adapts from the luminous intensity of the first zone to the luminous intensity of the high beam pattern. An automotive lighting device configured to perform these steps is also provided.
