Abstract

PURPOSE:To cut out the characters with high accuracy and without lowering the processing speed, by adding the histogram of a pattern. CONSTITUTION:The vertical projection is carried out for a character pattern stored in a pattern storing part 5'' through a vertical projecting part 6''. Then the dividing position of the character is calculated from the result of projection. The histogram of the black bit of the character pattern is obtained at a projection bit counter part 8 in a range of a certain number T of scanning lines and to the above-mentioned dividing position of the character. The point having the minimum value in the histogram is defined as the character dividing point.
