Abstract
A money identifying method and a device which can identify money with high precision and quickly by optimally binarizing a surface image of the money. The center coordinates and radius of subject coin C are extracted by a coin shape extraction section from the surface image of the subject coin C obtained by an area sensor, and an effective threshold calculation range is extracted by a threshold calculation range extraction sectionfrom the extracted center coordinates and radius of the coin. Further, a density histogram is created by a histogram generation sectionon the basis of the threshold calculation range, an optimum binary threshold value is calculated from the density histogram by a binary threshold calculation section according to a discriminating analysis, and the optimum binary threshold value is used to binarize an image for identifying the subject coin C.
