Abstract
A method and apparatus is proposed for the H and V-contour correction of a digitized video signal wherein after deriving a digital correction signal, both the main video signal and the correction signal are D/A converted. The H and V-detail signals are then derived from the analogue correction signal, are combined with a contour correction signal and are added in a suitable manner to the main video signal.
