Abstract
Apparatus for processing a color video signal produced by an imager. A low-pass filter supplied with the color video signal from the imager generates a luminance signal to which is added an outline component produced by a level correcting circuit that receives the color video imager signal and passes a level-corrected imager signal through a bandpass filter which extracts therefrom the outline component.
