Abstract
Abstract A score recognition apparatus initially reads a given musical score to form an original image data. The original image data is analyzed to successively recognize symbols contained in the musical score to produce a score code data. Then, a synthetic image data of the musical score is reproduced according to the score code data. The score recognition apparatus has a monitor receptive of the original image data and the synthetic image data to display an original image and a synthetic image in parallel to each other. An operation command is inputted to command a screen operation of the displayed image. The pair of the original and synthetic image data are concurrently processed according to the operation command to execute the screen operation of both the original and synthetic images in parallel manner. Further, the pair of the original and synthetic image data are compared with each other to detect a discrepancy portion between the original image and the synthetic image to produce a discrepancy image data. The monitor is controlled according to the discrepancy image data to visually indicate the discrepancy portion.
