Description
Claims (1)
- 트랜지스터(Q18~Q20), 저항(R18)으로 구성되어 바이어스전압(V1)에 따라 입력 비디오 휘도 신호중 어떤 일정레벨 이하를 컷-오프시켜 트랜지스터(Q5, Q6)의 베이스로 신호를 전달하는 신호입력부(가)와, 저항(R1~R4, R19), 콘덴서(C2), 가변전원(VR)으로 구성되어 트랜지스터(Q1, Q4)(Q2, Q3)의 바이어스 전압에 차등을 두어 트랜지스터(Q5, Q6)의 콜렉터 전류를 조절하는 전류조절회로부(나)와, 트랜지스터(Q1~Q8), 저항(R5~R10), 콘덴서(C1)로 구성되어 고주파 레벨의 차이를 디텍트하는 고주파 레벨차 디텍트부(다)와, 트랜지스터(Q11~Q14), 저항(R11~R15, R17)으로 구성되어 상기 고주파 레벨차 디텍트부(다)의 출력을 트랜지스터(Q9)를 통해 인가받아 증폭하여 출력하는 신호출력부(라)와, 트랜지스터(Q15~Q17)로 구성되어 상기 고주파 레벨차 디텍트부(다)를 출력과 원래의 입력 휘도신호(Y)를 합해서 한번더 보상해주는 신호 보상회로부(마)를 포함하여 구성된 것을 특징으로 하는 화상신호 찌그러짐 보상회로.
