<p><P>PROBLEM TO BE SOLVED: To provide a technique necessary for determining whether a target person is dazzled on a real time basis. <P>SOLUTION: In a light control device, the boundary distance corresponding to the position of the target person is extracted by referring to an undazzled-area map through the dazzling detection processing (S260, S270). The actually measured distance detected by a distance detector is compared with the boundary distance, and if the actually measured distance is equal to or less than the boundary distance (S270: YES), it is outputted that the target person is dazzled by a headlight of a user's own vehicle (S280). In the undazzled-area map, the maximum distance between the own vehicle and the target person in which the target person is dazzled by the headlight of the own vehicle is defined as the boundary distance, and the boundary distance is indicated for each divided area which is obtained by dividing the area of a picked-up image into a lattice. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
