Abstract

본 발명은 동영상분할 및 재구성용 라스터=블록변환기에 관한 것으로, 비디오메모리와 이 비디오메모리에 입력된 영상정보를 라스터-블록변환하는 라스터-블록변환콘트롤러를 구비하여 외부입력신호에 따라 디지탈데이터를 입력받아 라스터영상을 실시간처리하여 블록으로 구성하여 출력하도록 된 것이다.The present invention relates to a raster = block converter for video segmentation and reconstruction. It receives the data and processes the raster image in real time to form a block and output it.
