    Abstract: A detecting unit detects output-prohibit area information indicating an output-prohibit area from image data. An identifying unit identifies the output-prohibit area in the image data based on the output-prohibit area information detected by the detecting unit. A masking unit performs a masking on the output-prohibit area identified by the identifying unit. A rearranging unit rearranges an image of an area other than the output-prohibit area over the output-prohibit area on which the masking is performed by the masking unit. An outputting unit outputs image data obtained by rearranging the image by the rearranging unit.

  • Patent number: 8284456
    Abstract: A special pattern determination section determines whether a special pattern is included in a document image read by a document reading section. If the special pattern determination section determines that the special pattern is included, the breaking pattern applying section applies a breaking pattern to the document image, and the print image generating section accumulates image data of the document image applied with the breaking pattern into a memory. On the other hand, if it is determined that the special pattern is not included, the print image generating section accumulates the image data of the document image directly into the memory. Then, if it is set by a user so as not to print the breaking pattern, the controller deletes image data of the document image accumulated in the memory and applied with the breaking pattern.

  • Patent number: 8274679
    Abstract: This invention deters information leakage by a flexible monitoring method according to the characteristic of an image or document. A job analysis section analyzes a print job and separates image data and attribute information. An image generator generates print image data from the image data by referring to the attribute information. A digital watermark generator and synthesis section embed at least part of the attribute information in the print image data. An image transmitter transmits, to a monitoring server, the print image data with at least part of the attribute information added. A monitoring method selector selectively operates the image transmitter or the digital watermark generator and synthesis section based on the attribute information.

  • Patent number: 8243303
    Abstract: An image forming system includes an image forming apparatus and a mobile terminal. The image forming apparatus includes: a two-dimensional code output unit for outputting a two-dimensional code into which address information of the image forming apparatus is converted; and a job execution unit for executing a job transmitted from the mobile terminal that has accessed the image forming apparatus based on address information into which the two-dimensional code obtained by photographing an image of the two-dimensional code outputted from the image forming apparatus by the mobile terminal is inversely converted. The mobile terminal includes: a photographing unit for photographing an image of the two-dimensional code; an inverse converter for inversely converting the photographed two-dimensional code into address information; and a communication unit for accessing an address of the image forming apparatus, which address is obtained through the inverse conversion, to transmit a job.

  • Patent number: 8240551
    Abstract: The accuracy of reading a barcode embedded in a printed document is maintained, and at the same time, the amount of toner and the like consumed is reduced. When document information read by scanning is analyzed and the density of the document information is higher than a predetermined threshold vale, that is, when the printed document has a space enough to contain the barcode, the density of the barcode is set such that the density of the barcode is decreased as compared with a case where the density of the document information is lower than the predetermined threshold value. By changing the size of dots and the distance between the dots and thus decreasing the density of the barcode, it is possible to reduce the amount of toner and the like consumed. Then, the set barcode is synthesized with the document information, and the synthesized image is output.

  • Patent number: 8243336
    Abstract: An image forming apparatus embeds second class data that is different from sheet to sheet in first class data that is common throughout a printing operation. First and second unfolding sections unfold the first and second class data to image data. An image carrying body image examination section compares image data unfolded by the second unfolding section and picked up image data unfolded by the first unfolding section and prepared by an image carrying body image pickup section, and an intermediate transfer body image examination section compares image data unfolded by the second unfolding section and picked up image data unfolded by the first unfolding section and prepared by an intermediate transfer body image pickup section.

  • Patent number: 8237993
    Abstract: In order to prevent illegal copying more effectively in an image forming apparatus, when a specified ground pattern for preventing copying is detected in input image data, the detected ground pattern is emphasized in the image data. Alternatively, information for detecting the specified ground pattern is stored in a storage device, in order to detect the ground pattern with the stored information. When the ground pattern is not detected, a ground region in the image data is analyzed further to determine whether a different ground pattern exits or not. When a ground pattern is detected, information for detecting the ground pattern is stored in the storing device.

  • Patent number: 8234495
    Abstract: A method of digital watermarking selects a mapping of a digital watermark to audio or video content and an embedding gain to produce uniquely watermarked copies for distribution. The embedding method is implemented at points of distribution, including content servers or receivers. By applying varying mapping protocols and random gain, the digital watermark uniquely serializes copies. It also has a structure and embedding configuration that minimizes the effectiveness of collusion, averaging and over-embedding attacks.

  • Patent number: 8233165
    Abstract: A document processing apparatus which is capable of causing predetermined processes to be performed using sheets of one fixed format, in both of the case of scanning a fixed format sheet which has a description entered therein and the case of scanning a sheet which has a description entered therein but is other than the fixed format sheet. When a fixed format sheet having an entry made thereto is scanned in, a multifunction machine executes a first document processing process. When a fixed format sheet has been previously scanned in, if a sheet other than the fixed format sheet is scanned in, the multifunction machine executes s second document processing process. When no fixed format sheet has not been previously scanned in, if a sheet other than the fixed format sheet is scanned in, the multifunction machine executes a usual process.

  • Patent number: 8233197
    Abstract: The disclosure provides pantograph methods, apparatus and systems. Specifically disclosed is a method of rendering a pantograph including defining a foreground region associated with a pantograph, defining a background region associated with the pantograph, and applying a first UCR/GCR strategy to the background region and a second UCR/GCR strategy to the foreground region, whereby the foreground region is less discernable after the pantograph is rendered with a printing device relative to a reproduction of the rendered pantograph.
