Title: Video signal contour correction device
Inventor: MIHASHI YASUO
IPC: H04N5/208
Filed: 1988-05-13
Abstract: PURPOSE:To obtain a picture with high sharpness by generating a contour correction signal by two delay circuits, and each one of adder and subtraction circuits, slicing the tip including a noise component of the contour correction signal and adding the result to the original input video signal. CONSTITUTION:The 1st delay circuit 16 retarding the input video signal by a prescribed time and the 2nd delay circuit 17 retarding the time longer than the 1st delay circuit are provided to the device. Then the video signal is inputted to two delay circuits 16, 17, one adder circuit 18 and one subtractor circuit 20 to provide a thin and deep peak to emphasize the contour to the leading transient and the trailing transient of the video signal thereby forming a contour correction signal. The tip of the contour correction signal is sliced to obtain the contour correction signal not including the noise component. Thus, picture quality with excellent sharpness and high clarity is obtained.
