Abstract

본 발명은 키가 눌린 순간부터 그 이전의 영상 데이타를 메모리하여 시청자가 원하는 화면을 정확하게 다시 찾아 볼수 있도록 하는 티브이의 이전 화면 재생장치에 관한 것이다.The present invention relates to a TV's previous screen reproducing apparatus that allows a viewer to revisit the desired screen accurately by storing the previous image data from the moment the key is pressed.

이러한 본 발명은 많은 화면을 저장하기 위해 움직임 검출부(30)에서 화면의 움직임을 검출하여 정지 영상데이타는 제1프레임 메모리(40)에, 움직임 영상 데이타는 제2프레임 메모리(50)에 각각 저장하였다가, 키가 눌러지면 그 이전에 저장된 영상 데이타를 스캔하여 원하는 화면을 찾게 되고, 영상 데이타 합성부(60)에서 두 메모리(40)(50)의 출력을 합성하여 원래의 영상 데이타로 복원하게 된다.In order to store many screens, the present invention detects motion of the screen by the motion detector 30, and stores the still image data in the first frame memory 40 and the motion image data in the second frame memory 50, respectively. When the key is pressed, the previously stored image data is scanned to find a desired screen, and the image data synthesizing unit 60 synthesizes the outputs of the two memories 40 and 50 to restore the original image data. .
