`(54) Title: CHARACTER STRING EXTRACTION METHOD AND CHARACTER STRING EXTRACTION DEVICE
`
`(54) EEODE E711:X$§|JEE EESE J: )‘CE—EIJEIEEEE
`[I16]
`
`(57) Abstract: This character string extraction device comprises: a replace-
`ment information registration unit (80) wherein replacement information for
`replacing character information that is expected to be falsely recognized is
`registered; a candidate character data registration unit (81) wherein anticip—
`ated candidate character data is registered; an image information conversion
`unit (82) whereby read image information is converted to character informa—
`tion; a character information conversion unit (83) whereby, if a specific char-
`acter is included in the character information, the specific character is con—
`verted to a specified character and, if the specific character is not included,
`the converted character information is used, and read character data is gener—
`ated; a search character generation unit (84) whereby a prescribed character
`in read character data is converted to a special character and search character
`data is generated from the read character data; and a first comparison unit
`(85) whereby the search character data and the candidate character data are
`compared.
