VEHICLE LAMP SYSTEM, VEHICLE LAMP CONTROL DEVICE AND VEHICLE LAMP CONTROL METHOD

A vehicle lamp system includes an imaging unit which images a front of an own vehicle to generate image information, an imaging control unit which controls the imaging unit to perform an operation of generating image information with a first time period and an operation of generating image information with a second time period, a luminance analysis unit which detects luminance of individual regions in front of the own vehicle, an illuminance setting unit which determines a light distribution pattern. The illuminance setting unit, for an individual region whose luminance is within a high luminance range, sets an illuminance value such that luminance of the individual region decreases due to formation of the light distribution pattern, and for an individual region whose luminance is within a low luminance range, sets an illuminance value such that luminance of the individual region increases due to formation of the light distribution pattern.
