Abstract
A method of segmenting characters of a document image comprises the steps of dividing the document image into a plurality of divided regions and setting a check width with respect to each of the divided regions, where each check width is greater than or equal to a width of a corresponding one of the divided regions so that the check widths of two mutually adjacent divided regions partially overlap each other, reading image data amounting to one line of the document image, obtaining from the image data horizontal projections of each line data within each of the check widths, where each horizontal projection is a number of black picture elements in a corresponding data line within a check width and each data line is made up of a plurality of picture elements arranged horizontally, segmenting a line based on the horizontal projections, obtaining from the image data vertical projections, where each vertical projection is a number of black picture elements in a vertical direction, determining a character segmentation range based on the vertical projections, and segmenting each character of the line within the character segmentation range.
