Abstract
본 발명은 텔레비젼수상기에서 화면의 수직크기릍 조정하는 기술에 관한 것으로, 일반적인 텔레비젼수상기에 있어서는 화면의 상,하부분의 일부가 블록으로 저리된 와이드소오스의 입력에 대응하기 위하여 한개나 두개의 수직신장모드밖에 마련되어 있지 않아 그 블록부분을 정확하게 제거할 수 없는 결함이 있었는 바, 본 발명관 이를 해결하기 위하여 상,하측 블랙라인수릍 근거로 상,하측 블랙화면의 비율을 계산하여 소정 필드까지 이상이 없으면 그 상,하측 블럭화면의 비율을 근거로하여 수평, 수직방항으로의 편향을 조정하는 방법으로 화면의 크기를 보정하도록 하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for adjusting the vertical size of a screen in a television receiver. In a typical television receiver, one or two vertical extensions are used to cope with a wide source input in which part of the upper and lower portions of the screen is stored in blocks. There was a defect that the block part could not be removed correctly because only the mode was provided. To solve this problem, the ratio of the upper and lower black screens was calculated based on the upper and lower black line numbers, Based on the ratio of the upper and lower block screens, the screen size is corrected by adjusting the deflection in the horizontal and vertical directions.
