A method and a circuit for the additive and multiplicative spurious signal compensation of a video signal are proposed. For additive spurious signal compensation, a signal is derived from the "black level" signal, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is subtracted from the video signal. For multiplicative spurious signal compensation, a signal is derived from the "white level" signal, its reciprocal value is formed, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is multiplied with the video signal. A three channel system for color television signals is disclosed.
