PROBLEM TO BE SOLVED: To narrow down candidates even when the erroneous recognition or recognition invalidity of a following character is generated at the time of narrowing down the candidates of a predicted character string by the following character. SOLUTION: An input character is pattern recognized, and a character string to be predicted is prepared based on the recognition candidate character, and a character string having this character string at the leading part is retrieved and displayed from a word dictionary as the candidate of a predicted character string (steps 201-209). In this case, when the input of a following character is present, whether or not the candidate of a predicted character string including the recognition candidate character of the following character at a position corresponding to the following character is present among the candidates of the predicated character string is checked (steps 210-217). When the pertinent candidate is present as the result of checking, the predicated character string except the candidate is deleted, and the candidate is narrowed down (steps 218 → 219). When any pertinent candidate is not present, the candidate is narrowed down after the input of the next following character (steps 218 →210). |
