Banknote recognition apparatus and banknote recognition method

A banknote recognition apparatus for recognizing a denomination and an attribute of a banknote, the banknote recognition apparatus comprising:

• a detection unit configured to detect the banknote to be recognized;
• an evaluation-value calculation unit configured to calculate each evaluation value of the banknote, by using one evaluation-value-calculation-formula set composed of a combination of a plurality of predetermined evaluation-value calculation formulae, based on a detection result obtained by the detection unit;
• and
• a recognition unit for recognizing the denomination of the banknote to be recognized, by using one set of predetermined threshold values for each denomination of banknote to be handled, respectively corresponding to the plurality of evaluation-value calculation formulae, as well as configured to recognize the attribute of the banknote to be recognized, by using another set of predetermined threshold values for each denomination of banknote to be handled, respectively corresponding to the plurality of evaluation-value calculation formulae, based on each evaluation value of the banknote calculated by the evaluation-value calculation unit;
• wherein the recognition unit performs recognizing the denomination of the banknote and recognizing the attribute of the banknote, regardless of the recognized denomination of the banknote in parallel.

A banknote recognition method for recognizing a denomination and an attribute of a banknote, the method comprising:

• preparing one evaluation-value-calculation-formula set composed of a combination of a plurality of evaluation-value-calculation formulae, as well as preparing one set of threshold values for each denomination of banknote to be handled, respectively corresponding to the plurality of evaluation-value calculation formulae, and another set of threshold values for each attribute of banknote to be handled, respectively corresponding to the plurality of evaluation-value calculation formulae;
• detecting the banknote to be recognized;
• calculating each evaluation value of the banknote, by using the prepared one evaluation-value-calculation-formula set, based on a detection result of the banknote;
• recognizing the denomination of the banknote to be recognized, by using the threshold values prepared for each denomination of banknote, respectively corresponding to the plurality of evaluation-value-calculation formulae, based on each evaluation value of the banknote;
• and
• recognizing the attribute of the banknote to be recognized, by using the threshold values prepared for each denomination of banknote to be handled, respectively corresponding to the plurality of evaluation-value-calculation formulae, based on each evaluation value of the banknote;
• wherein recognizing the denomination of the banknote and recognizing the attribute of the banknote are performed in parallel.
