  • Patent number: 4075658
    Abstract: The graphic information contained in the image is converted by means of a television camera to a video signal constituted by a succession of lines, each line being sampled sequentially so as to obtain an ordered series of points which is stored in memory. The method consists in selecting a parent point forming part of an isolated figure of the image. All the points in which the level of blackening on the image exceeds an adjustable threshold value are isolated automatically by marking with an automaton coupled with the memory. All the marked points corresponding to the figure are extracted from the memory and the figure is reconstituted from the points.
