Abstract

문자 데이타를 이용하여 문자배경을 없애고 문자테두리생성 및 OSD 제어를 수행하는 OSD 문자테두리 생성 및 제어장치가 개시되고 있다. 본 발명에 따르면 스크린에 디스플레이되는 문자의 배경을 없애고, 배경의 위치에 영상신호를 디스플레이하여 영상신호의 디스플레이 비율을 높이는 장점을 가진다. 또한 스크린위에서 영상과 문자를 구별하기위한 일정크기의 문자테두리를 디스플레이하여 문자의 구별을 용이하게 하는 장점을 가진다. 또한 일정한 크기의 문자 테두리를 디스플레이하여 수려한 디스플레이 문자를 제공한다.Disclosed is an OSD character border generation and control apparatus for eliminating character backgrounds using character data, generating character borders, and performing OSD control. According to the present invention has the advantage of eliminating the background of the characters displayed on the screen, to display the image signal in the position of the background to increase the display ratio of the image signal. In addition, by displaying a text border of a certain size for distinguishing the image and the character on the screen has the advantage of easy to distinguish the character. In addition, by displaying a constant size character borders to provide a beautiful display character.
