Abstract

전자식 펜플로터 또는 그래픽 디자인에 이용되는 전자식 영상합성시스템이 기술되는바, 이 스스템은 합성하고자 하는 제1메모리 내용을 제3메모리에 일시적으로 저장하는데, 이저장방법은 제1메모리를 모니터에 표시하면서 전자펜을 사용하여 원하는 부분의 주위에 폐곡선을 그려서 이를 제3메모리에 일시저장한뒤 제2메모리의 내용을 모니터에 표시하고, 제3메모리에 저장된 폐곡선을 이동시켜 제2메모리의 위치에 위치시켜 제1메모리의 영상을 제2메모리의 영상과 합성시킴으로써 제1메모리의 화상색깔이 변하지 않고서 효율적으로 합성할 수 있도록 되어 있다.An electronic image synthesis system for electronic pen plotters or graphic designs is described. The system temporarily stores the first memory contents to be synthesized in the third memory, which displays the first memory on a monitor. Draw a closed curve around the desired part using the electronic pen and temporarily store it in the third memory, display the contents of the second memory on the monitor, move the closed curve stored in the third memory, and place it in the position of the second memory. By combining the image of the first memory with the image of the second memory, it is possible to efficiently synthesize the image color of the first memory without changing.
