Claim One:
1. A character recognition system comprising: a video input device which obtains character video signals by raster scanning characters which exist on a medium; a quantization unit which converts said character video signals into binary code video signals; a character centerline shaping device which transforms said binary code video signals into character centerline figures; a temporary memory device which temporarily stores said character centerline figures; a feature extract device which divides said character centerline figures in said temporary memory device into divided regions with lines, said lines being in the scanning direction or being at right angles wiith respect to said scanning direction, said divided regions being composed of columns having n bits which device takes out every column of partial centerline figures in said divided regions, said solumn being at a right angle with respect to said lines, and which device extracts the positions of a start point of said partial centerline figures in every divided region, positions of end points of said partial centerline figures in said every divided region, and displacements of said partial centerline figures from said start points to said end points, and; a sequential logic circuit which decides the categories of the character based on a sequence of the outputs of said feature extract device.
