VEHICLE LAMP SYSTEM, VEHICLE LAMP CONTROL APPARATUS, AND VEHICLE LAMP CONTROL METHOD

摘要

A vehicle lamp system 1 includes: a light source unit (10) capable of individually adjusting an illuminance of light to be radiated to each of a plurality of individual areas ahead of a host vehicle; an imaging unit (12) configured to take an image ahead of the host vehicle; an image analysis unit (114 configured to detect luminance of each individual area based on information obtained from the imaging unit; an illuminance setting unit (42) configured to set a target luminance value of each individual area and an illuminance value according to the target luminance value of the light to be radiated to each individual area; and a light source control unit (20) configured to control the light source unit based on the illuminance values set by the illuminance setting unit. The illuminance setting unit (42) is configured to set an illuminance value of which a difference from a target illuminance value for obtaining the target illuminance value is smaller than a difference between a previously set illuminance value and the target illuminance value and which is deviated from the target illuminance value, so as to gradually bring an actual luminance of each individual area close to the target luminance value.
