A method and apparatus for determining a class reference data record for classifying documents of value includes creating a class reference image using a multiplicity of reference images of already classified documents of value in the same class; and creating a class reference data record having at least one class reference parameter using the class reference image. The pixel and intensity values of the respective pixel in the class reference image are a function of the pixel values of the relevant pixels in the multiplicity of reference images of already classified documents of value in the same class. The method includes determining at least one quantitative property of a document of value to be classified; and classifying the document of value to be classified on the basis of a comparison between the quantitative property of the document of value to be classified and the class reference data record.

This object is solved by a device for inspecting a print material, including evaluation value acquisition means for inspecting a plurality of print materials and acquiring an evaluation value indicating quality of each print material, allowed-number-of-failed-product acquisition means for acquiring an allowed number of failed products among the plurality of print materials, determination criterion determination means for determining a determination criterion in which the number of failed products is equal to or smaller than the allowed number of failed products and a sum of evaluation values of passed products becomes a highest-quality value, pass and fail determination means for determining pass or fail of each print material on the basis of the determination criterion and the evaluation value of each print material, and output means for outputting a determination result of the pass and fail determination means.

The present invention provides a coin handling device that enables a simple and easy change of a way of handling a coin of which a type is difficult to determine according to the user needs. The coin handling device includes a detector that detects a feature of a coin, a determiner that determines a type of the coin based on the feature of the coin detected by the detector, a reception unit that receives from an operating person handling settings that designate a way of handling the coin that is an indeterminate coin of which the type is not determined and for which multiple options of the type are extracted by the determiner, and a handling unit that handles the indeterminate coin based on the handling settings received by the reception unit.

A bill recognizing and counting apparatus includes an operation unit that receives setting of bill processing modes including a denomination mode, a counting mode, a different-denomination recognition mode, and an authenticity determination mode; a feeding and transporting mechanism; and a control unit that performs control for changing a processing speed according to the bill processing mode. When the bill processing mode is in the counting mode, the different-denomination recognition mode, or the authenticity determination mode, the control unit increases the processing speed by setting the feeding and transporting mechanism to a higher speed than the speed set in the denomination mode. The increase in speed is in accordance with a reduced time necessary to process a reduced amount of data associated with the denomination mode.

Examples include authenticating a banknote having at least one printed area on a substrate thereof. An optoelectronic capturing device captures the at least one printed area on respective substrates of each of a plurality of copies of the same type of banknote to be authenticated and provides raw image data to a processor unit for visualizing the respective captured printed areas as an image on a display device connected to the processor unit. The processor unit partitions the respective image into a plurality of regions of interest (ROIs) and selectively provides different features for authentication of the certain type of banknote from the raw image data of each of the ROIs. Different selected features each form different classification models and authentication of a banknote to be presently authenticated is carried out using a plurality of classification models.

A sensor for verifying value documents and designed to determine the luminescence time constant of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence time constant of the value document in the sensor. The relative movement between the value document and the sensor causes movement effects, resulting in a distortion of the intensity curve from which the luminescence time constant is derived. The luminescence time constant is corrected using a sensor-specific corrective factor ascertained for the velocity of the movement of the value document during the verification process. For this purpose, different sensor-specific corrective factors are used for different examples of sensors that are nominally identical in design and are part of the same sensor production series.

A serial number recognition parameter determination apparatus includes: a generation unit, an identification unit, and an evaluation index calculation unit. The generation unit generates a parameter set of a program, the program being used when a paper sheet handing apparatus identifies, from an image of a paper sheet, character present regions in which characters that form a serial number are present. The identification unit identifies, from an image of the paper sheet, the character present regions by using the parameter set that is generated by the generation unit. The evaluation index calculation unit calculates an evaluation index of the parameter set based on the character present regions that are identified by the identification unit.
