Claims (1)

화상 데이타를 기억하는 화상기억수단과, 이 화상기억 수단으로부터 독출되는 검출대상화소의 화상데이타와 상기 검출대상화소의 주위에 인접하여 존재하는 8화소의 각 화상 데이터에 의해 얻어지는 일치출력 데이터와 화상의 경계가 연속하는 방향을 가르키는 방향 데이터와를 어드레스로 하여 일률적으로 정하는 방향데이타가 미리 기입된 방향 데이터기억 수단과를 구비하고, 상기 방향데이타 기억수단으로부터 직전에 독출된 방향데이타와 상기 일시출력데이타와를 독출 어드레스로하여 상기 기억수단으로부터 상기 화상기억수단에 기억된 화상테이타가 나타내는 화상의 경계에 대응하는 방향 데이터를 독출하도록 한 것을 특징으로하는 화상의 경계검출처리장치.The image storage means for storing the image data, the image data of the detection target pixel read out from the image storage means, and the coincidence output data and the image obtained from each of the 8 pixel image data adjacent to the detection target pixel. And a direction data storage means in which direction data uniformly determined by addressing direction data indicating a direction in which the boundary is continuous is written, and the direction data and the temporary output data read immediately before the direction data storage means. And the direction data corresponding to the boundary of the image indicated by the image data stored in the image storage means is read from the storage means as a read address. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
