Verfahren zur Rauschreduktion eines Bildsignals

摘要

In a noise reduction process for image signals with a recursive filter (3, 4, 5), the fedback image signals (G*) are converted on the basis of the motion vector into the motion phase of the input image signals (S). In the event of conversion errors, recursion is appropriately reduced (k, 1-k). Local noise reduction (29) is provided for revealed areas and for a release mode.
