PURPOSE: A method for improving disturbance signal interference of active type 3D glasses is provided to improve a crosstalk phenomenon and a flicker phenomenon by blocking a disturbance signal of a 3D synchronizing signal. CONSTITUTION: A 3D image device is operated in a 3D mode to receive a 3D synchronizing signal from an IR(Infrared Ray) transmitting unit(S202). A receiving unit receives a 3D glass reception state from 3D glasses to output the 3D glass reception state to a control unit. If the 3D glass reception state is normal, the control unit transmits the 3D synchronizing signal as a basic value by controlling the IR transmitting unit(S204,S206). Otherwise, the control unit transmits the 3D synchronizing signal with intensity stronger than the basic value by controlling the IR transmitting unit(S208).
