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.

A system and method for automatic identification of photocopied documents is disclosed wherein the method is performed by capturing an image of a marked printed document; decoding a digital watermark embedded in the image, obtaining a mark identifier; recovering, by searching a database, at least one calibration parameter associated with the mark identifier; applying a discrete Fourier transform to the image, obtaining a frequency matrix; obtaining at least one maximum frequency value in the frequency matrix; comparing the at least one maximum frequency value with at least one calibration parameter; determining, on the basis of the comparison, if the marked printed document is an original document or a photocopied document.

Disclosed is a banknote processing method and device. The banknote processing method includes: scanning a substrate through the image acquisition module while acquiring banknote image data through an image acquisition module to obtain substrate image data; acquiring a characteristic value of the substrate image data; calculating a change value of the characteristic value of the substrate image data relative to a reference characteristic value; judging whether the change value is greater than a preset threshold value; and configuring parameters of the image acquisition module if it is judged that the change value is greater than the threshold value.

An object of the present invention is to avoid as much as possible a state where recognition results with respect to the same paper sheet become different. Provided is a paper sheet identification system including a first paper sheet identification device and a second paper sheet identification device. The second paper sheet identification device includes a second identification unit that identifies the authenticity of paper sheets based on a second set value, and a first acquisition unit that acquires previous process data.

Techniques for detecting counterfeit checks include using sensors to determine correspondence between items detected on a check using machine vision. Correspondence between different items on a received check is used to generate a check score, which is compared to a risk-based threshold to determine how a transaction involving the check should be handled.

One object is to correct with a high accuracy a plurality of magnetic sensors arranged inside a small magnetic detection apparatus. The magnetic detection apparatus that detects magnetism of a paper sheet being transported includes a plurality of magnetic sensors arranged in a linear manner in a direction orthogonal to a transport direction of the paper sheet; an excitation member having a plate-shape that extends in an arrangement direction of the plurality of magnetic sensors; and a control unit that generates a calibration magnetic field by passing an electric current in the arrangement direction through the excitation member, and obtains a correction value for correcting variation in sensitivity of the plurality of magnetic sensors based on detection results of the calibration magnetic field detected by the plurality of magnetic sensors.

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.

Techniques for detecting counterfeit checks include using sensors to determine correspondence between a portion of sensed check information and related information; analyzing behavior related to accounts to a check deposit transaction; and controlling check depositing through user interface controls or communication. These techniques can be employed individually or in combination.
