Abstract

PURPOSE: To obtain sharp picture with speed modulation for characters and graphic signals, by providing the analog switch and delay circuit in the circuit.
CONSTITUTION: The luminance signal being the output of the character signal reception circut 13 is fed to the edge detection circuit 11 via the analog switch 10, and the color signal in R, G and B is fed to the analog switch via the delay circuit 29 from the circuit 13. The switches 6 and 10 are subject to the control of the circuit 13, and when the control signal is present, the output of the circuit 13 is passed through and the output of the video detection circuit 3 is passed when no signal is present. The circuit 11 detects the changing part of white and black in the video signal, speed modulation of electron beam is made by the speed modulation circuit 12, to clear the edge part. Further, there is phase difference between the edge signal and color signal, the switch 6 is passed via the delay circuit 29. Thus, the character signal is made for the speed modulation and the picture is very sharp.
