Contour correcting circuit |
摘要 |
A contour correcting circuit emphasizes the contour of a video signal by increasing the rise and fall characteristics of the signal by using a high frequency extraction circuit in combination with a delay circuit and an adder adding in the delay output to the extracted signal. An amplitude limiter limits the adder output to between upper and lower limits of the input video signal and a second delayed signal.
