Abstract

본 발명은 사용자 의도에 따라 현재 영상을 확대하기에 적당하도록 한 영상기기의 화면 확대장치에 관한 것으로, 종래에는 스포츠 또는 영화 등 특정 채널 방송시 화면의 특정부분 영상을 확대할 수 없었으나, 본 발명에서는 수직 화면 확대신호 발생부(13)가 영상처리부(5)의 색신호를 지연하여 그 지연된 색신호 및 지연되지 않은 색신호를 순번적 교대로 발생하여 수직 구동부(12)가 수직폭이 넓게 편향하도록 하므로써 표시부(8)는 현재 영상을 확대하여 디스플레이하므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a screen magnification apparatus of a video device that is suitable for enlarging a current image according to a user's intention. In the related art, although a specific portion of a screen of a specific channel broadcast such as sports or a movie cannot be expanded, the present invention In this case, the vertical screen magnification signal generator 13 delays the color signal of the image processor 5 and sequentially generates the delayed color signal and the undelayed color signal so that the vertical driver 12 deflects the vertical width wide. 8 enlarges and displays the current image, thereby improving the above-mentioned defect.
