Abstract

PURPOSE: To make it possible to emphasize outline correction on a bright screen by forming an outline correction signal on a basis of the video signal before gamma- correction and by adding this correction signal to a gamma-corrected video signal in outline signal generation circuit.
CONSTITUTION: A color video signal (G signal) is taken out from the preceding stage of gamma-correction circuit 3, and an outline correction signal is formed in outline signal generation circuit 5 on a basis of this video signal. Consequently, in this case, when the signal of a step wave as shown in figure (a) is supplied as a color video signal, the outline correction signal as shown in figure (d) is obtained from outline signal generation circuit 5 and is added to the Y signal, which is obtained from delay circuit 6, in adder circuit 7, and the outline of the Y signal is corrected and emphasized. Thus, outline correction effects are increased.
