<p>An apparatus for correcting the vertical contour of a video signal so as to reduce the noise without impairing the overall effect of correcting the contour. This apparatus (VCP1) emphasizes the vertical contour (Ev) of a video signal (S1) by correcting vertical contour components (S1v, S1v') of the video signal (S1) by a predetermined correction quantity (K), and is provided with a vertical contour component extracting unit (3) for detecting the components (S1v, S1v') from the video signal (S1), vertical contour component correlation detecting units (3, 29, 8c, 8d, 4) for detecting a correlation (Sj1) among vertical contour components (Sb, Sb', Sb'') neighboring one another in the horizontal direction, and a control unit (5) for determining the quantity (K) of correction based on the correlation (Sj1). The quantity (K) is varied depending upon the correlation (Sj1). <IMAGE></p> |
