Claim:
A headlamp light distribution control device for a vehicle, the headlamp light distribution control device comprising: an image acquisition unit configured to acquire an image of a forward area of an own vehicle; an extraction unit configured to extract a forward vehicle from the image of the forward area acquired by the image acquisition unit; a distance acquisition unit configured to acquire a distance from the own vehicle to the forward vehicle; a judgment unit configured to extract a lamp configured by a pair of lamps mounted in the forward vehicle from the image of the forward vehicle extracted by the extraction unit if the distance from the own vehicle to the forward vehicle acquired by the distance acquisition unit is less than a predetermined value, and judge whether the extracted lamp is in a both lamps lit state where both of the pair of lamps are lit or in a single lamp lit state where only one of the pair of lamps is lit; and a control unit configured to set a shielded area in an irradiation area of a headlamp of the own vehicle so as to prevent an area including the lamp of the forward vehicle from being irradiated if the judgment unit judges that the extracted lamp is in the both lamps lit state, and set a shielded area in the irradiation area of the headlamp of own vehicle so as to have a margin in right and left directions larger than the shielded area set upon the both lamps lit state if the judgment unit judges that the extracted lamp is in the single lamp lit state.
