Abstract
The invention relates to a process for the contour correction of the luminance signal in a television camera in which a horizontal contour signal is added to a relatively poorly defined luminance signal in order to increase the vertical resolution, and a vertical contour signal is added thereto in order to increase the horizontal resolution. An additional contour signal (W.sub.HV) is formed from the product of the horizontal contour signal (W.sub.H) with the vertical contour signal (W.sub.V), which additional contour signal is deducted from the luminance signal (W.sub.O).
