Abstract
A chord information extraction device includes a character group extractor, a determiner and a corrector. The character group extractor extracts a character group corresponding to chord information from score image data representing a music score. The determiner determines whether the character group extracted by the character group extractor follows a predetermined chord notation rule. In a case where the character group extracted by the character group extractor does not follow the chord notation rule, the corrector corrects the extracted character group to follow the chord notation rule.
