Abstract:
The character recognition apparatus recognizes characters from a read document original to correct a character string as a character recognition result in a word unit with a space character as a separator. The character recognition apparatus includes a circumscribed rectangle formation portion which forms a circumscribed rectangle for each recognized alphabet character string, a fixed-pitch font determination portion which determines whether or not a font is a fixed-pitch font based on a distance between center lines in a width direction of adjacent circumscribed rectangles, a portion for determining an excess space character which determines, in the case of a fixed-pitch font, that the space character is an excess based on that a width of a space character in the character string is narrower than a predetermined width, and a portion for deleting the space character determined as an excess from the character string.
