Abstract
A system and method control a vehicular headlamp for preventing a shadow area between a low beam and a high beam of a headlamp using a camera unit. The method includes periodically determining whether a high beam of the vehicular headlamp is lit or illuminated. Upon determining that the high beam is illuminated, the method includes determining whether a darkness cell is formed in front image data of the vehicle, which is transmitted from a camera unit. Upon determining that the darkness cell is formed, the method includes changing a leveling motor to be directed upward by 1 step and storing a changed number of steps. Upon determining that the darkness cell is not formed, the method includes driving the leveling motor by the pre-stored number of steps.
