A method for determining a noise component in a video signal is proposed, in which the difference between a delayed and an undelayed video signal is formed. In order to be able to measure the noise component as precisely as possible, the delayed and the undelayed video signal are assigned to at least two different processing channels depending on their respective amplitude. At least two peak values for the noise signal for two different amplitude ranges are determined from the absolute value of the difference between the two video signals.Furthermore, a circuit is proposed which is suitable for implementing the method proposed.
