ABSTRACT:
A character input device for inputting a character by extracting and recognizing a character from an image of a document photographed by a photographing device includes the photographing device. The device stores a recognition result of the extracted and recognized character and reliability indicative of sureness of recognition. Character recognition results of images obtained by repeatedly photographing a whole or part of the document are compared in order to input the character based on a character recognition result whose reliability is highest. A character input method includes adding reliability indicative of sureness of recognition to a recognition result of the character, comparing character recognition results of images obtained by repeatedly photographing the whole or part of the document, and selecting a character recognition result whose reliability is highest. A computer-readable medium encoded with a character input program for inputting a character by extracting and recognizing a character is also disclosed.
