The kinescope dynamical luminous focusing device comprises the first and the second video-frequency amplifiers, the outputs being connected correspondingly to focusing and control electrodes of the kinescope. The voltage focusing source is connected to a kinescope focusing electrode. The selection box of a loop signal, a threshold unit, a commutation unit and a reference voltage source is entered, the output being connected to the first commutation unit input. The selection box of the loop signal is a video signal input.
