Claims (3)
- R.G.B신호 데이타에 각기 비례하는 화소별 노광량이 되도록 액정의 일정 구동주기(T) 및 일정투과율(α)에 따른 R.G.B라인의 화소별 노광횟수(n')를 각기 결정한 후, 상기 일정구동주기(T)의 게이트 전압 및 액정 투과율(α)을 일정하게 하는 액정구동전압으로 R.G.B라인의 해당화소 액정을 상기 R.G.B라인 화소별 노광횟수(n')로 구동시켜 감광매체를 수평라인별로 노광시키고, 그 감광매체를 이송시켜 임의의 수평라인을 R.G.B라인으로 중복노광 시키도록 하는 것을 특징으로 하는 칼라 비디오 프린터의 노광방식.
- 제1항에 있어서, R.G.B라인 화소별 노광횟수(n')는 소정의 스텝으로 분류하는 R.G.B신호 데이타가 해당된 스텝에 특정상수(K)를 곱하여 R.G.B신호 데이타에 비례하도록 결정하는 것을 특징으로 하는 칼라 비디오 프린터의 노광방식.
- 제1항에 있어서, 액정의 투과율(α)을 최대 투과율로 고정하는 것을 특징으로 하는 칼라 비디오 프린터의 노광방식.* 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
