PROBLEM TO BE SOLVED: To efficiently recognize a musical score by separating parts which constitute thin lines from musical score image data, detecting symbols composed of thin lines from the separated thin-line images, and detecting thick symbols from the remaining thick image. SOLUTION: A scanner 12 optically scans a musical score and generates binary or gray-scale image data, and the read image information is inputted to a RAM 3 or HDD 4 through a scanner interface circuit 13. Here, the parts constituting the thin lines are separated from the musical score image data, and the symbols composed of thin lines are detected from the separated thin-line images. Then the thick symbols are detected from the remaining thick image. Thus, the thick part, thin longitudinal lines, and thin lateral lines in the musical score image are separated as the preprocessing of musical score recognition to constitute a recognizing method which is sensuously close to a read of the musical score by a human, and the symbols or components of the symbols can efficiently be recognized from separated images to improve the recognition rate. |
