Claim 0:
1. A vehicle lamp control device comprising:
an imaging unit configured to take an image ahead of a host vehicle;
a target analysis unit configured to detect target objects ahead of the host vehicle based on information obtained from the imaging unit;
a tracking unit configured to repeatedly determine a specific target object from the target objects detected by the target analysis unit and to repeatedly detect displacement of the specific target object based on a detection result of a luminance analysis unit configured to detect luminance of each of a plurality of individual areas ahead of the host vehicle based on the information obtained from the imaging unit; and
a pattern formation control unit configured to determine a formation range of a luminance-dependent light distribution pattern in which illuminance values are set depending on the luminances detected by the luminance analysis unit, and a formation range of a luminance-independent light distribution pattern in which illuminance values are set independently of the luminances detected by the luminance analysis unit,
wherein position information of a specific individual area corresponding to a position of the specific target object is updated based on the repeatedly detected displacement,
wherein a light distribution pattern to be formed by a light source unit of a vehicle lamp is determined based on the detection result of the luminance analysis unit and a detection result of the tracking unit, and
wherein the pattern formation control unit, based on a detection result of the luminance analysis unit, sets an area having a high possibility that a target object to be recognized will exist therein, as the formation range of the luminance-dependent light distribution pattern, and sets an area having a low possibility that a target object to be recognized will exist therein, as the formation range of the luminance-independent light distribution pattern.
