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.

A vehicle head light control apparatus controls a lighting apparatus included in a headlight of a vehicle to avoid irradiating to an irradiation avoidance region which is a region overlaps with a detected object. The lighting apparatus can irradiate an irradiation region which is a set of irradiation sections. When the vehicle is in a manual driving state, irradiating to the irradiation sections included in an adjacent region which is a region adjacent to the irradiation avoidance region is reduced as a distance between the irradiation section and the irradiation avoidance region becomes shorter. When the vehicle is in an autonomous driving state, the adjacent region is not provided or the adjacent region becomes smaller as compared with a case where the vehicle is in the manual driving state.
