Abstract

PURPOSE:To segment a character accurately by excluding the noise of the circumference of the character to be recognized, by performing projection vertically and horizontally by turns by an optical character reader. CONSTITUTION:A character 13 read by a read part 2 under the command of a control part 5 is stored in a segmentation area 3a which has A bits horizontally and B bits vertically. Projection is performed by a vertical projecting circuit 9 to the overall horizontal B-bit width of the area 3a to store projection data DAT1 in a vertical projection register 11. This data includes noises 15-17 of part of an adjacent character, a stain, etc., in addition to the character 13, and black blocks 19, i.e.. their shadows are formed at digits x1-x2, and x3-x4. A data processing part 12 judges the maximum-width black blocks 19 of the digits x3- x4 to be the projection of the character 13 to be recognized, thereby regarding effective width as 3b. Then, similar operation is performed vertically to obtain an effective area 3c, and this is repeated to obtain a 3e, thereby segmenting the character accurately.
