To obtain correction information for automatic leveling control without a special environment. A device controlling the vehicular lamp axis in accordance with attitude change in the pitch direction of a vehicle including: a detection part detecting a first and a second acceleration; a correction part obtaining variation of the vehicle angle at a stop based on the two accelerations of a first and a second timing, obtaining vehicle angle while traveling based on the two accelerations while traveling, and obtaining and retaining a correction angle based on the difference between the two; an angle calculation part obtaining the vehicle angle while traveling based on the two accelerations, and obtaining an actual vehicle angle by subtracting the correction angle from the vehicle angle while traveling; and an optical axis control part generating a control signal based on the actual vehicle angle, and providing the control signal to the vehicular lamp.
