Abstract

본 발명은 일반적인 영상신호를 소정의 비율로 증가하여 광폭 화면을 생성하게 하는 광폭 모드전환시에 화면의 불안정한 순간절환 현상을 방지할 수 있도록 한 광폭 텔레비젼 수상기에 있어서, 입력되는 아날로그 영상 신호를 디지탈 영상데이타로 변환시키는 아날로그/디지탈 변환수단(1)과, 사용자의 지령에 의한 광폭화면으로의 변경여부롤 판정하는 판정수단(10)과, 이 판정수단(10)으로부터 인가되는 판정신호를 수직동기에 동기화시켜 출력하게 하는 수단을 포함한 마이콤(20)과, 상기 아날로그/디지탈 변환수단(1)으로부터 디지탈 영상데이타를 입력하고 광폭 변환을 위한 제처리를 수행하며, 마이콤(20)으로부터 인가되는 제어신호(CS)에 따라 디지탈 영상데이타를 출력하는 직렬영상처리수단(2)과, 이 직렬영상처리수단(2)으로부터 출력되는 디지탈 영상데이타를 아날로그 영상 신호로 변환시키는 디지탈/아날로그 변환수단(3)을 포함하여 구성된 것을 특징으로 한다.The present invention provides a digital video signal for inputting an analog video signal in a wide television receiver that can prevent unstable instantaneous switching of the screen during wide mode switching, which increases the general video signal by a predetermined ratio to produce a wide screen. The analog / digital conversion means 1 for converting the data, the determination means 10 for determining whether to change to the wide screen according to a user's instruction, and the determination signal applied from the determination means 10 to the vertical synchronization. A control signal applied from the microcomputer 20 and a digital signal inputted from the analog / digital converting means 1 and performing processing for wide-width conversion, and Serial image processing means (2) for outputting digital image data in accordance with CS), and digital output from the serial image processing means (2). And digital / analog converting means (3) for converting video data into analog video signals.
