PURPOSE:To improve the recognizing efficiency, by setting a window in response to a recognition object of a musical score to recognize the object with a histogram in the window or its movement. CONSTITUTION:The density data of the musical score 1 for one record's share is read optically by a scanner or the like to obtain the density distribution curve (histogram) 2 in the abscissa direction X. Then, the density distribution curve 2 in the direction X read in this way is converted into the density distribution curve (histogram) 3 in the ordinate direction Y. That is, the density distribution curve 3 in the direction Y which is correspond to the X distribution is obtained by accumulating the values of the curve 2 in the direction X and moving sequentially the accumulation upward or downward. |
