PURPOSE:To recognize a musical score at a high speed by using a staff detecting circuit, a head detecting circuit, a measure line detecting circuit, etc. CONSTITUTION:The picture signal from an image pickup device 2 is binarized by a binary-coded circuit 4 and is inputted to a picture storage circuit 5 and a staff detecting circuit 6. The staff detection result is read out by an arithmetic means 8, and an inclination correcting circuit 9 is started in accordance with the result. the inclination correcting circuit 9 reads out the picture from the picture storage circuit 5 and gives the regular picture signal to a head detecting circuit 12, a measure line detecting circuit 13, and a bus interface 26. the operating means 8 reads out detection results of the head detector 12 and the measure line detector 13 through a bus 24 and transfers them to one of operating means 27-29 through a bus 25 together with information related to the staff. An arithmetic means 30 gathers identification results and adjusts them finally and outputs them as the music recognition result. |
