ABSTRACT:
In a method and an apparatus for determining a frequency for the sampling of an analog signal, which is provided to a digital screen for representing an image on the same, at least two areas succeeding in line direction will be established in the image to be displayed. In each of the established areas, a sample phase will be determined, for which a contrast in the established area is maximum or a minimum. Subsequently, a local course of the sample phase will be determined in the line direction based on the determined sample phases. The sampling frequency will be determined based on a base value and a modification value, which is derived from the local course of the sample phase.
