Line portions of the character pattern in a character recognition device which have a thickness less than a selected standard value are thickened by a thickening circuit to the selected value. The line thickness of the character is then uniformly thinned by a thinning circuit and the thickening process is repeated. A correction circuit may be provided to prevent the continuity of the character from being broken in the thinning circuit.

Character pattern line thickness regularizing device

The character pattern from the scanner is stored in its original form in an auxiliary memory and in compressed form in a main memory. The slant and the horizontal and vertical second-order moments of the character pattern are sensed in the main memory, and normalized as the character pattern is shifted from the auxiliary memory to the main memory.
