Abstract

본 발명은 영상신호의 개선된 마스킹 장치에 관한 것으로, 피사체에 대한 제1 영상신호와 제2 영상신호가 각 A/D변환부에서 디지탈 영상신호로 각각 전환되어, 각 마스킹부에서 각각 좌측시각과 우측시각에 대한 영상신호로 마스킹된 다음, 혼합처리부에서 입체영상신호로 디스플레이하기 위해 합성된다.The present invention relates to an improved masking apparatus for a video signal, wherein the first video signal and the second video signal for a subject are converted into digital video signals at each A / D converter, respectively, Masked with the video signal for the right eye, and then synthesized for display as a stereoscopic video signal by the mixing processor.

이 때, 휘도레벨 검출부에서 각 카메라에 포착된 원래 영상신호의 휘도레벨이 휘도레벨 검출부에서 검출되어 각 휘도레벨의 평균레벨이 출력되고, 혼합처리부에서 합성된 영상신호의 휘도레벨이 휘도레벨 검출부로부터 제공되는 평균레벨에 상응하여 휘도레벨 조절부에서 조절된 다음 D/A변환부에서 아날로그 영상신호로 전환되어 디스플레이 제공되므로써, 영상신호의 마스킹시에 감소된 휘도신호를 증가시킬 수 있으므로, 보다 밝고 선명한 영상신호를 얻을수 있도록 한 것이다.0At this time, the luminance level of the original video signal captured by each camera by the luminance level detector is detected by the luminance level detector, and the average level of each luminance level is output. The brightness level is adjusted according to the average level provided, and then converted into an analog video signal in the D / A converter and provided as a display, thereby increasing the reduced brightness signal when masking the video signal, thereby making it brighter and clearer. The video signal can be obtained.
