That illuminating pattern of the headlight HL which appears on a screen 3 disposed in front of the vehicle CA is pictured. The optical axis of the headlight HL is adjusted based on an image of the illuminating pattern. A distribution of illuminance of the illuminating pattern along a scanning line which bridges a light portion B and a dark portion D of the image of the illuminating pattern is measured. A position of a reference point which serves as a reference in adjusting the optical axis is obtained from that point GP on the scanning line which corresponds to a crossing point G of a first straight line A1 and a second straight line A2. The first straight line A1 is obtained from a portion corresponding at least to one of the light portion B and the dark portion D of a curve BB which represents the measured distribution of illuminance. The second straight line is obtained from a portion corresponding to a transient region T which is positioned between the light portion B and the dark portion D.

Ce motif lumineux du phare HL qui apparaît sur un écran 3 placé devant le véhicule CA est illustré. L'axe optique du phare HL est réglé en fonction d'une image du motif lumineux. Une distribution de l'éclairement du motif lumineux le long d'une ligne de balayage qui franchit une partie claire B et une partie obscure D de l'image du motif lumineux est mesurée. La position d'un point de référence qui sert de référence pour le réglage de l'axe optique est obtenue à partir de ce point GP sur la ligne de balayage qui correspond au point de croisement G d'une première ligne droite A1 et d'une seconde ligne droite A2. La première ligne droite A1 est obtenue à partir d'une partie correspondant au moins à l'une de la partie claire B et de la partie obscure D d'une courbe BB qui représente la distribution de l'éclairement mesurée. La seconde ligne droite A2 est obtenue à partir d'une partie correspondant à une région transitoire T qui se trouve entre la partie claire B et la partie obscure D.
