Abstract
A method for enhancing an edge transition in a video signal comprising the steps of receiving a video signal including an edge transition, generating a correction signal for the edge transition, applying the correction signal to the video signal to produce a corrected signal and restricting the amplitude of the corrected signal to extend between extended maximum and minimum amplitude limits in dependence on the measured maximum and minimum amplitudes of a predefined pattern of pixels adjacent to the edge transition.
