  • Patent number: 11785164
    Abstract: An object is to provide a copy function that guarantees intensity of embedded information. At the time of copying a printed material, embedded information is extracted from a scanned image obtained by scanning the target printed material. Then, in a case where it is confirmed that the copy-target printed material is an authentic document by the extracted embedded information, the embedded information extracted from the scanned image is reconfigured and printed and output.

  • Patent number: 11706365
    Abstract: To make it possible to easily determine a printed material of an electronic document proved to be an authentic original document and a copied material thereof. In a case where a printed material is copied, embedded information is extracted from a scanned image obtained by scanning the target printed material. Then, in a case where it is confirmed that the copy-target printed material is an authentic document, the printed material is printed and output by adding information indicating being a copied material thereto.

  • Patent number: 11676267
    Abstract: An object is to perform both quality maintenance of a printed material and suppression of a reduction in productivity of a printing apparatus by performing density correction processing at appropriate timing that takes into consideration the state of the printing apparatus. The above-described object is implemented by accumulating inspection results of printed sheets that are output from the printing apparatus and causing the printing apparatus to perform density correction processing in a case where a color defect in which a destination color is not reproduced occurs successively a predetermined number of times or more at positions at which the color defect does not overlap another defect.

  • Patent number: 10728531
    Abstract: An image display system selects at least one pixel from among a plurality of pixels of first to fourth images captured by imaging apparatuses, and embeds timestamp information into data representing the selected pixel. As the pixel in which timestamp information is embedded, a pixel which is displayed at a position which is relatively low in visibility for the user is selected so as to reduce degradation in image quality.
