Abstract
본 발명은 컴퓨터 화면에 디스플레이 되는 영상을 비디오 카메라로 촬영하여 이를 다시 방송용 화면이나 별도의 디스플레이 장치에 전송시켜 디스플레이 시킬 때, 컴퓨터의 신호를 입력하고 필요한 화각 확대율에서 화소(pixel)정보의 열화없이 수직 주파수차의 플리커(flicker)나 인터레이스에 의한 필드 플리커를 제거시키는 비디오 촬영용 영상신호 변환장치에 관한 것으로, 소스 화상을 제공하는 컴퓨터에서 제공된 화상 데이터와, 이를 촬영하는 비디오 카메라의 주파수 동기를 확립하고, 소스 화상 데이터의 출력 라인수의 변화없이 주사할 수 있도록 한 다음 상기와 같이 변환된 데이터를 타 디스플레이 장치에 주사하여 비디오 촬영을 하므로, 화면의 플리커 제거는 물론 화상의 해상도 저하의 문제를 제거하는 효과가 있다.The present invention inputs a computer signal and displays the image displayed on a computer screen with a video camera and transmits it to a broadcast screen or a separate display device, and displays the image without deterioration of pixel information at a necessary angle of view magnification. A video signal converting apparatus for video shooting that eliminates field flicker due to flicker or interlacing of a frequency difference, the method comprising: establishing image data provided by a computer providing a source image and frequency synchronization of a video camera photographing the same; The video can be scanned without changing the number of output lines of the source image data, and then the converted data is scanned on another display device to shoot video, thereby eliminating the problem of flickering the screen and reducing the resolution of the image. There is.
