To provide an apparatus for rough classification of words that allows features of words to be stored in a vocabulary storage division to be generated from character codes of the words so that the words can be efficiently selected. A candidate character selection division detects areas likely to be characters from a word image, and a character recognition division recognizes candidate characters generated in candidate character selection division and converts them into character codes. A number-of-characters estimation division estimates the number of characters of the entire word image and the number of characters of the areas between candidate characters, a word description division generates word description equivalent to a state transition graph from the recognition results of candidate characters and the estimated number of characters of candidate character separations. A vocabulary selection division selects vocabulary that can be checked against word description among the vocabulary stored in vocabulary storage division
