Abstract

비디오 카메라의 장막기능 제어장치가 기술되는바, 이는 피사체의 촬영시 블루화면을 모니터의 각 모서리로부터 삼각형식으로 점차적으로 증가시켜 페이트 아웃기능을 수행하고, 페이드 인시에는 화면 중앙으로 부터 블루화면을 각 모서리를 향해 점차적으로 감소시켜 고차원의 페이드 인/아웃 기능을 달성한 것이다.The control function of the curtain function of the video camera is described. When the subject is captured, the blue screen is gradually increased from each corner of the monitor in a triangular manner to perform a fade out function. It gradually decreases toward the edge to achieve a higher level fade in / out function.
