Portable optical reader, optical reading method using the portable optical reader, and computer program
First Claim
1. A portable optical reader comprising:
- imaging unit configured to image a character string as a reading target;
character string recognition unit configured to recognize the character string based on an image captured by the imaging unit;
reading format storage unit configured to store a plurality of reading formats defining an attribute of a character string;
first search processing unit configured to search a first reading format matched with a character string recognized by the character string recognition unit among a plurality of stored reading formats;
second search processing unit configured to search a second reading format in which a character string matched with the first reading format matches as a partial character string among a plurality of stored reading formats; and
notification unit configured to notify a possibility of a reading error regarding the recognized character string based on a search result of the second search processing unit.

Abstract
The present invention provides a portable optical reader, an optical reading method using the portable optical reader and a computer program capable of detecting a high possibility of a reading error and notifying a user of a possibility of a reading error. A character string as a reading target is imaged and a character string is recognized based on the captured image. A plurality of reading formats defining an attribute of the character string is stored, and a first reading format matched with the recognized character string among a plurality of stored reading format is searched. Among the plurality of stored reading formats, a second reading format in which a character string matched with the first reading format as a partial character string is searched. Based on the search result, a possibility of a reading error regarding the recognized character string is notified.
