Abstract

[목적] 정상규격의 화면에 대해 와이드 규격의 화상을 절환가능하게 표시한다.
[구성] 표시패널(1)은 정상규격에 따른 화면(11)에 행렬 배치한 화소(12)를 갖고, 와이드 규격의 영상신호 Vsig를 입력할때 화면(11)에 횡방향의 와드 표시를 가능하게 한다. 수직주사회로(14)는 1행분의 화소(12)를 순차선택한다. 수평주사회로(15)는 선택된 1행분의 화소(12)에 대하여 와이드 규격의 영상신호 Vsig의 1수평 기간분을 기록한다. 타이밍 발생기(3)는 수직주사회로(14)의 순차선택을 타이밍제어하고, 와이드 규격의 영상신호 Vsig로부터 수평기간분을 소정갯수 샘플링하여 화면(11)의 종방향으로 압축된 와이드 표시를 행한다. 타이밍 발생기(3)는 또한 수직주사회로(14) 및 수평주사회로(15)를 제어하여 와이드 표시를 행했을때 화면(11)의 종방향 상하에 남겨진 잔여부에 대해 흑신호를 영상신호보다 고속으로 기록한다.
