  • Patent number: 7508988
    Abstract: An image processing apparatus includes a receiving mechanism configured to receive a request, from at least one different image processing apparatus connected via a network, for transmission of a codestream generated in a way such that image data is divided into at least one region, each region being hierarchically compressed and stored in the image processing apparatus, a decomposing mechanism configured to decompose a codestream and retrieve the codestream in a component unit, an extracting mechanism configured to extract a target region from the codestream, a primary priority assigning mechanism configured to assign priority to the target region extracted by the extracting mechanism, and a primary transmitting mechanism configured for transmission of the codestream, decomposed in a component unit corresponding to the target region, to the different image processing apparatus requesting transmission of the codestream based on the priority assigned by the primary priority assigning mechanism.

  • Publication number: 20070097403
    Abstract: An image processing system is disclosed that is able to provide an image suitable for a specified application. The image processing system includes a first image processing device for separating an input image into plural divisional images, which are processed by different image processing methods, in accordance with the output device of the input image; and a second image processing device for producing an output image suitable for a specified application from the divisional images. The first image processing device includes an image area division section for determining which of a first area and a second area, sub image areas of the input image belong to, and a selection section which uses the sub areas of the input image as the divisional images according to the determination results of the image area division section.

  • Patent number: 7140534
    Abstract: There are provided a data recording medium, a reading device for reading the data recording medium, a recording device for reading the data recording medium and recording data to other media, and methods thereof able to prevent forgery without comparing visible information and data stored in a built-in electronic circuit chip. The reading device is for reading a data recording medium including a sheet portion visibly printed with an image and a data storage unit recorded with control data.
