Abstract

본 발명은 부호화 효율을 높이기에 적합한 윤곽선 부호화 장치에 관한 것으로, 종래에는 영상 데이터를 윤곽선에 따라 일괄적으로 분할하여 윤곽선의 특성에 따라 윤곽선 부호화함으로써 이후 디스플레이되는 경우에 있어서, 배경 부분이 필요 이상으로 세밀하게 묘사되고 물체 부분은 거칠게 묘사되는 문제가 발생하였으나, 본 발명에서는 물체 부분과 배경 부분을 분리하여 각각 부호화함으로써 물체와 배경을 원하는 정도로 세밀하게 묘사할 수 있으며, 한번 윤곽선 부호화되어 전송된 배경은 다시 윤곽선 부호화하여 전송할 필요가 없기 때문에 전체적인 윤곽선 부호화의 효율이 증대하여 상기 결점을 개선시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contour coding apparatus suitable for increasing coding efficiency. Conventionally, in the case where the image data is collectively divided according to the contour and contour encoded according to the characteristics of the contour, the background portion is more than necessary. Although a problem of fine detail and roughness of object parts occurs, in the present invention, the object and the background part are separately encoded to describe the object and the background as precisely as desired. Since there is no need to send contour coding again, the overall contour coding efficiency can be increased to improve the above-mentioned shortcomings.
