  • Patent number: 11941901
    Abstract: In some examples, a smartphone or tablet includes a device able to generate a digital identifier of a copy that includes at least one print image. The device includes at least one optoelectronic detection device that detects the at least one print image and creates a representation that includes a multiplicity of pixels. The device further includes a unit that evaluates brightness intensities of the pixels, that segments the representation into multiple fields that each are composed of pixels of the representation, and that provides each of these fields with a piece of position information. The unit also ascertains, in each of these fields of adjoining pixels, a difference in their respective brightness intensities, and displays the differences as a frequency distribution. A display device further displays the digital identifier of the respective copy of the relevant printed product in the form of a graphical and/or alphanumerical display.

  • Patent number: 11780220
    Abstract: In some examples, photographic mapping of an object takes place during transport at a fixed position by means of a line camera in a sequence of recording periods. An exposure device is exposed for an exposure time that is dependent on the duration of the on-time of the line camera. Each strip-shaped portion of the object to be photographically mapped is exposed, within a recording period, asynchronously for the duration of a first exposure time to white light and for the duration of a second exposure time either to ultraviolet light or to IR light. Each strip-shaped portion of the print image to be photographically mapped is alternately exposed by the exposure device, within the recording period photographically mapping the portion, to white light and either to UV light or to IR light during the duration of the on-time of the line camera.
