ABSTRACT:
A method for processing a video signal comprises defining a successively shifted scan window with respect to the signal level of each picture element from which said video signal has been derived, totalizing the quantum numbers of the picture elements in the scan window corresponding to the original screen dot, and reconstructing black picture elements corresponding to the total value of the quantum numbers faithfully to the area of the original dot, and an apparatus for carrying out the method.
