Abstract

고정된 폰트를 다양한 크기의 TV 모니터에 사용할 경우, 시각적 효과를 증가시키기 위해 문자 또는 도형의 세로폭을 축소 또는 확대시킬 필요가 있는데, 온스크린 발생부와 혼합기 사이 에 세로폭 조정 회로를 부가함으로써 이를 구현할 수 있다. 세로폭 조정회로에는 온스크린 발생부에서 발생한 신호를 분리하여 일부는 지연시키고 일부는 그대로 통과시켜 이 두신호를 AND게이트 또는 OR게이트 등으로 연산함으로써 문자또는 도형의 세로폭을 축소 또는 확대시킬 수 있다.When using fixed fonts on TV monitors of various sizes, it is necessary to reduce or enlarge the height of characters or figures in order to increase the visual effect, by adding a height adjustment circuit between the on-screen generator and the mixer. Can be implemented. In the vertical width adjustment circuit, the signal generated by the on-screen generator is separated, partly delayed, and partly passed through, so that the two signals are operated as an AND gate or an OR gate. .
