Abstract

PURPOSE: To pick up the topological characteristics of the character pattern stably with high accuracy, by calculating the distance by direction and that by slope of each point indicating the character in the pattern region, and deciding the slope information through the comparison of both the intervals at the standard value.
CONSTITUTION: The binary signal generated by scanning of the scanning section 100 is sequentially stored in the pattern memory 210. The content of the section 210 is in raster scanning toward the any direction, and stored at direction interval calculator 310. The section 310 counts the number of connections of black points, and the interval of directions is obtained. This distance by slope is transferred to the slope component determining section 320, which gives distance with slope by using the directional interval and the slope component by using the distance by slope and that by direction, and the code showing the slope is stored at a given location of one word. The slope information thus obtained is stored in the memory section 210, then the input character is decided at the section 500 and the result is output from the output terminal 700.
