Patent
Circuit arrangement for increasing the definition of color contours of a color television signal using selective edge enhancement
TL;DR: In this article, a slope detector detects the slope of the luminance signal and, when a predetermined slope value is exceeded, produces a detection signal for energizing a counter, in which, as soon as the counter is energizing, the value of the color difference signal is stored and is available as an output signal.
Patent
Circuitry for increasing the sharpness of colour edges
TL;DR: In this article, a slope detector (2l) detects the slope of the luminance signal and outputs a detection signal if it exceeds a certain slope amount for activating a counter (28) from.
Patent
Circuit arrangement for the selective feeding of a video signal
TL;DR: In this paper, the authors proposed a low-distortion manner for feeding a television signal composed of at least one luminance and one chrominance signal separately from the luminance signal.
