1. An apparatus for controlling an in-vehicle lighting environment, the apparatus comprising:
a passenger state determination unit that determines a state of a passenger using a gaze of the passenger photographed by a camera of a vehicle;
a driving state determination unit that determines a driving state of the vehicle using an acceleration value measured by an acceleration sensor of the vehicle;
an external environment state determination unit that determines an external environment state of the vehicle using an external illuminance value measured by an external illuminance sensor of the vehicle; and
a lighting environment control unit that controls an illuminance and a color of a first light disposed inside the vehicle based on data determined by at least one determination unit among the passenger state determination unit, the driving state determination unit, and the external environment state determination unit,
wherein the passenger state determination unit determines that the state of the passenger is a rest mode when the gaze of the passenger is not identified, and
wherein the lighting environment control unit controls the illuminance of the first light to be changed to an illuminance set according to the external illuminance value when the passenger state determination unite determines that the state of the passenger is in the rest mode.
