Abstract

본 발명은 캠코더의 영상 합성 방법 및 장치에 관한 것으로, 종래에는 카메라 모드 동작시에는 통상적으로 라인 아우트(line out) 모드로 사용하고 있으므로 합성 모드 동작시 입출력 단자를 절환해야 하는 문제점이 있다. 이러한 점을 해결하기 위하여 본 발명은 단순한 키 조작으로 입출력 단자를 자동으로 절환하도록 하고 합성 신호 또는 각각의 신호를 기록 또는 표시할 때 기록과 표시를 별도로 조작 가능케 하여 선택하고자 하는 영상신호를 먼저 확인 후 기록 동작을 수행하도록 할 수 있도록 한 것으로, 본 발명에서는 별도의 메모리없이 카메라 모드에서 라인 입력 신호를 이용하여 합성 신호를 생성하고 라인 입력 신호, 카메라 입력 신호 또는 합성 신호중 하나를 임의로 선택하여 확인하면서 편집을 수행할 수 있으므로 편집효과를 극대화 할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for synthesizing an image of a camcorder. In the related art, since the camera mode is normally used in a line out mode, an input / output terminal must be switched during the synthesis mode. In order to solve this problem, the present invention automatically switches input and output terminals by simple key operation, and when recording or displaying a composite signal or each signal, recording and display can be operated separately, and then the image signal to be selected is first checked. In the present invention, a composite signal is generated using a line input signal in a camera mode without a separate memory, and an arbitrary selection of a line input signal, a camera input signal, or a synthesized signal is confirmed and edited. This can maximize the editing effect.
