  • Patent number: 10803260
    Abstract: The present disclosure provides a QR code graphic manufacturing device, which comprises a gray-scaled adjusting module, a data-hiding module, and an error-diffusion module. The gray-scaled adjusting module is used to adjust a gray-scaled value of an original image to generate a modified gray-scaled image. The data-hiding module and the error-diffusion module are respectively used to process the modified gray-scaled image and a QR code, and to generate a QR code graphic with a better hidden effect.

  • Patent number: 10621482
    Abstract: A method of creating a graphic Quick Response (QR) code includes a picture and first and second two-dimensional barcodes combined through a halftoning technique. The graphic QR code includes a plurality of module units, each having a plurality of sub-modules. Information dots containing first information for the first two-dimensional barcode are provided, and each of the information dots of the first two-dimensional barcode is located at a central sub-module of each of the module units. The first information is readable by a scanning device. Information dots containing second information for the second two-dimensional barcode are provided, and each of the information dots of the second two-dimensional barcode is located at one of the other sub-modules. A position of each of the information dots of the second two-dimensional barcode is capable of being located by inputting a key through a decryption program for obtaining the second information.
