Abstract
본 발명은 가상 영상 영역을 사용하여 물체가 영상 밖으로 움직였을 때 이것을 가상 영상 영역에 담아 두었다가 이 물체가 다시 영상내로 들어오는 경우 가상 영상 영역으로부터 움직임 보상하도록 함으로써 전송해야 할 데이터양을 줄이고 재생 영상의 화질을 개선시키는 가상 영상 영역을 이용한 영상의 가장자리 부분 보상 방법 및 구조에 관한 것이다.According to the present invention, when an object moves out of an image using a virtual image region, the object is stored in the virtual image region, and when the object comes back into the image, motion compensation is reduced from the virtual image region to reduce the amount of data to be transmitted and improve the quality of the playback image. An edge compensation method and a structure of an image using an improved virtual image region are provided.
원영상 영역이외에 가상 영상 영역을 설정하는 단계와, 이전 프레임에서 물체가 영역 밖으로 움직이는 경우, 이것을 가상 영상 영역에 담아두는 단계와, 상기 이전 프레임에서 가상 영상 영역에 있던 물체의 부분이 현재 프레임에서 원영상 영역으로 들어오는 경우 가상 영상 영역으로부터 움직임 보상하는 단계로 구성된다.Setting a virtual image region other than the original image region, storing an object in the virtual image region when an object moves out of the region in a previous frame, and a part of an object in the virtual image region in the previous frame Comprising a motion compensation from the virtual video area when entering the video area.
