A fraud confirmation assisting apparatus includes a light source, a reading sensor, and processing circuitry. The light source irradiates an object to be read with light in at least an invisible wavelength range. The reading sensor has sensitivity at least in the invisible wavelength range. The processing circuitry performs a reading operation on the object to be read by a combination of the light source and the reading sensor, and outputs a plurality of pieces of fraud confirmation information based on read information output from the reading sensor by the reading operation.

A method of obtaining a plurality of infrared images of a banknote that involves simultaneously illuminating the banknote with infrared light at a first wavelength and infrared light at a second wavelength, capturing an image of the banknote with an RGB camera, obtaining from both a first output channel signal and a second output channel signal of the RGB camera sensor where the intensity distribution of the infrared light at the first wavelength and the intensity distribution of the infrared light at the second wavelength uses a first calibration coefficient and a second calibration coefficient of the RGB camera sensor, producing separate infrared images of the banknote at the first wavelength and the second wavelength from the respective intensity distributions.

An interactive kiosk for reading a document, the kiosk comprising: a transparent platform for supporting a document; a first camera disposed below the transparent platform; a mirror assembly comprising at least one mirror disposed below the transparent platform, the mirror assembly being arranged to reflect light from the underside of the transparent platform to the lens of the first camera; and a control unit connected to the first camera, the control unit being configured to receive content from the first camera and extract data from a document disposed on the transparent platform.

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.

A method of authenticating and/or identifying a security article including a first image includes superimposing at least partially the first image of the article with a second image. The second image may be produced by an electronic imager. The method further includes performing a relative movement between the first and second images so as to make it possible to observe an item of information relating to authentication and/or identification of the security article during the relative movement between the first and second images.

An optical device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. In some examples, individual ones of the first and second segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the first and second segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.
