Abstract

본 발명은 자막데이터처리장치에 의해 신호처리되어 화면표시되는 자막데이터에 있어서는 소정의 색채를 갖고서 표시될 수 있도록 하고 있는 바, 해당자막이 화면표시부분이 자막의 색채와 유사하게 되는 경우에는 시청자가 자막을 용이하게 읽을 수 없게 된다는 단점을 해결하기 위해 이루어진 것으로 비디오테이프에서 재생되는 자막데이터의 색채레벨을 검출함에 의해, 해당자막이 표시되는 화면표시영역이 보색처리될 수 있도록 하는 텔레비디오의 자막표시영역 보색처리제어장치를 제공한다.According to the present invention, the caption data that is signal-processed by the caption data processing apparatus and displayed on the screen can be displayed with a predetermined color. When the subtitle screen display part becomes similar to the color of the caption, It is made to solve the disadvantage of not being able to read the subtitles easily, and by detecting the color level of the subtitle data played on the video tape, the subtitle display of the tele video can be complementary to the screen display area where the subtitle is displayed. An area complementary color processing control device is provided.

그에 따라 본 발명은 모드절환부(30)의 비디오모드로의 모드절환에 의해 비디오테이프로부터 재생되는 영상신호가 영상증폭부(22)를 통해 신호증폭되고 그 자막데이터가 자막신호처리수단(28)에서 자막신호처리되어 영상신호처리무듈(24)에서 영상신호처리되어 영상출력부(26)를 통해 영상재생되도록 이루어진 텔레비디오에 있어서; 상기 자막신호처리수단(28)으로부터의 자막신호의 R(Red)색채성분과 G(Green)색채성분 및 b(Blue)색채성분을 필터링하는 색채필터수단(30,32,34)과, 상기 필터링된 R색채성분과 G색채성분 및 B색채성분의 색채레벨을 각각 검출하는 색채레벨검출수단(36,38,40) 상기 검출된 R.G.B색채 레벨에 대한 보색처리를 위한 기능프로그램데이터가 메모리된 메모리수단(44) 및 상기 색채레벨검출수단(36,38,40)에서 각각 검출된 R.G.B색채 레벨에 대한 보색처리를 위한 기능프로그램데이터가 메모리된 메모리수단(44) 및 상기 색채레벨 검출수단(36,38,40)에서 각각 검출된 R.G.B색채레벨치를 입력받아 상시 메모리수단(44)의 기능프로그램테이터에 의거하여 비교연산한 결과로 상기 영상신호처리모듈(24)에 자막표시영역의 보색처리를 위한 보색처리를 위한 보색제어신호를 발생하는 제어수단(46)을 구비하여 구성된 것을 특징으로 한다.Accordingly, in the present invention, the video signal reproduced from the video tape is amplified by the video amplifier 22 through the mode switching of the mode switching unit 30 to the video mode, and the caption data is processed by the caption signal processing means 28. In the tele-video which is processed by the caption signal is processed in the video signal processing module 24, the video signal is reproduced through the video output unit 26; Color filter means (30, 32, 34) for filtering the R (Red) color component, the G (Green) color component, and the b (Blue) color component of the caption signal from the caption signal processing means (28); Color level detecting means (36, 38, 40) for detecting the color levels of the R color component, the G color component, and the B color component, respectively; memory means for storing functional program data for complementary color processing on the detected RGB color level (44) and the memory means 44 and the color level detecting means 36, which store the function program data for the complementary color processing for the RGB color levels detected by the color level detecting means 36, 38, and 40, respectively. Complementary color processing for the complementary color processing of the subtitle display area in the image signal processing module 24 as a result of comparison operation based on the function program data of the memory means 44 at the time of inputting the RGB color level values respectively detected at (40). For generating a complementary color control signal for And a means (46) is characterized in that configured.
