Description
Claims (1)
- 휘도 및 색도신호를 갖는 영상신호의 천이부분에 프리슈트 혹은 오버슈트를 부가하는 윤곽보정장치에 있어서, 영상신호의 수평주사선간의 상관량을 검출하는 수단과 ; 영상신호중의 고주파성분량을 검출하는 수단과 ; 상기의 검출된 상관량과 고주파 성분량을 A/D변환하는 수단과 ; 상기의 디지탈 변환된 상관량과 고주파 성분량을 가산하는 수단과 ; 상기의 가산된 신호에 대한 역보정된 신호값을 참조테이블로서 저장하는 기억수단과 ; 상기 기억수단에서 출력되는 역보정된 신호값을 D/A변환하는 수단을 포함하는 것을 특징으로 하는 윤곽보정장치.
