PURPOSE: A vehicle lamp and a control method thereof are provided to improve performance of a lamp device by compensating deviation between a gaze angle of a camera and an aiming angle of a lamp unit. CONSTITUTION: A detection unit detects an object in a driving direction of a vehicle(S200). A gaze angle of the detection unit is recalled(S210). A lamp unit irradiates light based on the gaze angle. The detection unit detects an irradiation angle of the irradiated light(S240). The detection unit recalls a reference irradiation angle(S250). The gaze angle is compensated(S270). The lamp unit irradiates light based on the compensated gaze angle(S290). [Reference numerals] (AA) Start; (BB) No; (CC) Yes; (DD) End; (S200) Detect an object in a driving direction of a vehicle; (S210) Call a prestored gaze angle of a detection unit; (S220,S290) Calculate the angle between the object and the detection unit based on the called gaze angle; (S230) Irradiate a point corresponding to the calculated angle with lights; (S240) Detect the irradiation angle of the lights provided by a lamp unit; (S250) Call a reference irradiation angle corresponding to the called gaze angle; (S260) Irradiation angle≠Reference irradiation angle; (S270) Compensate the gaze angle to correspond to the difference between the irradiation angle and the reference irradiation angle; (S280) Calculate the angle between the object and the detection unit based on the compensated gaze angle; (S300) Store the compensated gaze angle; (S310) Output the difference between the irradiation angle and the reference irradiation angle to a driver
