  • Publication number: 20140071475
    Abstract: A document management system includes an image forming apparatus, an acquisition section, a document information management server, and a function limiting server. The acquisition section receives identification information of a document to be printed. The document information management server maintains an attribute information table that has identification information and attribute information of different documents stored therein, and retrieves attribute information of the document corresponding to the identification information received by the acquisition section. The function limiting server limits print functions of the image forming apparatus when printing the document having the identification information received by the acquisition section according to a printing policy that is based on the attribute information of the document retrieved by the document information management server.

  • Publication number: 20130293931
    Abstract: According to one embodiment, the media reuse determination apparatus has a decoding section, a reusability determination section, and an output section. The decoding section decodes information related to management of a print media attached to the print media obtained by using a reading apparatus to read the object having the information recorded thereon, and it carries out error correction during decoding of the information. On the basis of the result of the error correction carried out during decoding of the information by the decoding section, the reusability determination section determines whether or not the print media can be reused. The output section outputs the result of the determination made by the reusability determination section.

  • Publication number: 20130070266
    Abstract: A system includes a receiving unit and a controller. The receiving unit receives data about the number of processes performed in an image forming unit to form an image with a decolorable color material and data about the number of processes performed in a decolorizing unit to decolorize an image formed with the decolorable color material. Based on the data received by the receiving unit the controller calculates the number of media in user's use in a condition after they are subjected to image formation by the image forming unit and before they are decolorized by the decolorizing unit. The controller deters image formation by the image forming unit if the number of the media in user's use exceeds a first threshold, and allows the image forming unit to form an image if the number of the media in user's use does not exceed the first threshold.

  • Patent number: 7719711
    Abstract: There is provided a decoding apparatus and a decoding method which are for using compressed data efficiently by making the resolutions of the individual components differ from one another. A decoding apparatus decodes compressed data that represents an image signal composed of a plurality of components as a compressed code by making the resolutions of the individual components differ from one another. The decoding apparatus basically comprises input sections 5-Y, 5-I, 5-Q which decode compressed data and take in the individual components independently, a reduction circuit 5-Y-1 which reduces and changes a size corresponding to the processing unit and resolution of any one of the components, and a conversion section 5-6 which converts into a decoded image signal in a specific format by using reduced components and uncompressed components.
