Abstract

PURPOSE: To realize a fixed speed scanning of the picture by using the auxiliary memory unit effectively and thus to increase the detection speed for the concatenated regions.
CONSTITUTION: The tentative region numbers are given sequentially to each point of the picture signals obtained through scanning of the picture image, and at the same time the correspondence is secured the adjacent regions scanned already. And in case the same concatenated regions are decided, the decision result is memorized in triangular matrix type memory M1 and M2. Then the final decision is given to the concatenated components based on the contents of memory M1 and M2, and the actual region numbers are allotted to the components. After this, the tentative region numbers are rewritten to the actual region numbers to be then converted into the picture featuring the different value with every concateneated region. In this way, the detection speed can be increased for the concatenated regions as well as a fixed speed scanning becomes possible for the pictures.
