Abstract

본 발명은 부화면을 통해서는 약정된 화면 조정 표준 패턴을 출력하고 주화면을 통해서는 조정가능한 화면조정 패턴을 출력함으로써, 사용자로 하여금 화면조정을 실행함에 있어서 참고적인 근거를 제공할 수 있도록 된 부화면을 이용한 화면조정 기능을 갖춘 텔레비전 수상기에 관한 것으로, 수신된 방송신호에 대하여 부화면(PIP)처리가 가능하도록 영상신호를 처리하는 영상처리부와, 이 영상처리부로부터 출력되는 색조신호(R, G, B) 및 휘도신호(Y)를 근거로 후단의 CRT를 구동함으로써 주화면 및 부화면에 대한 영상화면을 제공하도록 된 CRT구동부를 구비한 텔레비전 수상기에 있어서; 사용자가 화면조정 명령을 선택입력하기 위한 기능선택키와, 화면조정기능 선택시 주화면 및 부화면으로 출력되게 되는 소정 화면조정패턴에 대한 OSD패턴데이터를 저장하는 OSD패턴 메모리, 소정 제어신호에 따라 상기 OSD패턴 메모리에 저장된 주화면측 OSD패턴에 대응되는 색조신호를 영상 처리부로 출력하는 제 1 OSD발생회로, 소정 제어신호에 따라 상기 OSD패턴 메모리에 저장된 부화면측 OSD패턴에 대응되는 색조신호를 영상처리부로 출력하는 제 2 OSD발생회로, 및 상기 화면조정 기능선택키를 통해 화면조정명령이 입력되게 되면 장치전반을 구동제어하여 주화면과 부화면을 통해 화면조정을 위한 소정 OSD패턴이 각각 출력되도록 제어하는 제어수단으로서의 마이크로 프로세서를 포함하여 구성된 것을 특징으로 한다.The present invention allows the user to provide a reference basis in performing the screen adjustment by outputting a standardized screen adjustment pattern through the sub-screen and an adjustable screen adjustment pattern through the main screen. The present invention relates to a television receiver having a screen adjustment function using a screen, comprising: an image processing unit for processing a video signal to enable sub-picture processing on a received broadcast signal; and color tone signals R and G output from the image processing unit. (B) and a television receiver having a CRT driving unit configured to provide a video screen for a main screen and a sub-screen by driving a CRT of a rear stage based on the luminance signal Y; Function selection key for the user to select and input the screen adjustment command, OSD pattern memory for storing OSD pattern data for the predetermined screen adjustment pattern to be output to the main screen and sub-screen when the screen adjustment function is selected, according to the predetermined control signal A first OSD generation circuit which outputs a color tone signal corresponding to the main screen side OSD pattern stored in the OSD pattern memory to an image processing unit, and a color tone signal corresponding to the sub-screen side OSD pattern stored in the OSD pattern memory according to a predetermined control signal; The second OSD generation circuit outputs to the image processing unit, and when a screen adjustment command is input through the screen adjustment function selection key, the entire device is driven to output predetermined OSD patterns for screen adjustment through the main screen and the sub screen, respectively. It characterized in that it comprises a microprocessor as a control means for controlling so as to.
