<p>From a register in which a two-valued pattern is stored there is sequentially extracted information along three vertical scanning lines, from which information over the region of 3 by 3 bits is selectively extracted in succession by means of data selectors. Features are searched by comparing the thus extracted information with a mask having a predetermined pattern in bits. The feature extractor of character and figure is adapted to store the variety, coordinate and total number of the thus searched features to separate registers for comparison with the features of standard characters.</p> |
