A vehicle lamp system includes an imaging unit, a luminance analysis unit, an illuminance setting unit, a light source unit and a light source control unit. The light source control unit controls the light source unit to periodically form a reference light distribution pattern including at least a part of a fixed illuminance area which does not depend on the illuminance value determined by the illuminance setting unit. The illuminance setting unit determines the illuminance value based on a reference detection result including the detection result of the luminance analysis unit obtained under the formation of the reference light distribution pattern, and updates the illuminance value when the new reference detection result is obtained.
