Portable Optical Reader, Optical Reading Method Using The Portable Optical Reader, And Computer Program

An optical reading method capable of being executed by a portable optical reader equipped with imaging unit for imaging a character string as a reading target, character string recognition unit for recognizing a character string based on an image captured by the imaging unit, and reading format storage unit for storing a plurality of reading formats defining an attribute of the character string,

• wherein the portable optical reader includes:
• a first process for searching a first reading format matched with a character string recognized by the character string recognition unit among a plurality of stored reading formats;
• a second process for searching a second reading format in which a character string matched with the first reading format among a plurality of stored reading formats matches as a partial character string;
• and
• a third process for notifying a possibility of a reading error regarding the recognized character string based on a search result of the second search processing unit.
