  • Publication number: 20060215203
    Abstract: This invention provides a data storage output apparatus that includes an input component, plural output components, a storage component and a conversion component. The input component inputs data. The plural output components output data in different respective data formats. The storage component stores data in an intermediate format, which can be converted to data formats required by the respective plural output components. The conversion component converts the data stored in the storage component to a data format corresponding to the output component and outputs the data to the output component.

  • Patent number: 7002709
    Abstract: The reproduction of a copy inhibit image and the abuse of data through a network are to be prevented without sacrificing various page editing functions. An image read unit scans an original placed on an original carrying table and thereby generates RGB color image signals of multi-value. An image processing unit performs various image processing and, upon detection of a copy inhibit original, performs image working for preventing faithful reproduction of the copy inhibit original. An image storing unit temporarily stores page by page original images provided from the image processing unit. If a copy inhibit image is contained in the original images, the image working is performed by the image processing unit to prevent faithful reproduction and the images after the image working are stored in the image storing unit. An image output unit performs a printing operation in accordance with image data outputted from the image processing unit.

  • Publication number: 20050271578
    Abstract: A particulate titanium oxide is obtained which has a large specific surface area and a high crystallinity with few internal defects, and thus a high photocatalytic activity as a photocatalyst is expected. Particulate titanium oxide in which the particles are box-shaped polyhedra is used as the photocatalyst. The particles are each a box-shaped polyhedron composed of one or more titanium oxide single crystalline polyhedron. When this single crystalline polyhedron has a flatness ratio of 0.33 to 3.0, the crystallinity is even higher. The particulate titanium oxide typically has a rutile transition ratio R(700-24) of not more than 7.5% and a rutile transition ratio R(500-24) of not more than 2.0%. Titanium oxide particles of these shapes are manufactured by feeding titanium tetrachloride vapor and oxygen into a reaction tube made of silica glass and applying heat from outside the tube to effect thermal oxidation.

  • Patent number: 6901170
    Abstract: An image processing apparatus and a recording medium which can improve the quality of a color document image. Smoothing conditions which are defined by three parameters of “filter size”, “offset”, and “overlap” are set. An edge image which was generated in an edge detection processing is referred to, and a determination is made as to whether an edge pixel exists in a noticed region. When the edge pixel does not exist in the noticed region, a smoothing processing is carried out. When the edge pixel exists in the noticed region, it is determined inappropriate to effect the smoothing processing, and the process goes to a subsequent processing without effecting the smoothing processing. The processing is carried out until the image scanning ends. When the image scanning ends, the next smoothing conditions are set and the processing which is the same as the one described above is performed.

  • Patent number: 6873436
    Abstract: An image processing apparatus and a recording medium which can improve the quality of a color document image are provided. An input image is converted into an image having low resolution. A subtractive color image is generated using the converted image having low resolution. From the subtractive color image, adjacent pixels which are allocated to the same representative color are unified so as to extract an FCR (Flat Color Region) candidate region. A region candidate is redetermined using an image having resolution which is higher than the subtractive color image. Next, a boundary of the FCR is detected and an ultimate FCR is determined. Selection of a representative color of the determined FCR is carried out, and a specific color processing which replaces a color which is close to a pure color with the pure color is effected. Finally, image regeneration is carried out by overwriting and drawing (synthesizing) the FCR on the input image.

  • Publication number: 20030098983
    Abstract: In case of a “N-up” function, a correcting unit executes a correcting process operation with respect to an image read by an image input unit, a editing unit executes a magnification changing process operation, and thereafter, “N” sheets of images are placed side by side to form a single synthesized image at a time when the processed image is stored into a storage unit 15. When transmitting the synthesized image, an attribute of the image set from a U/I is added to the synthesized image and the control unit transmits the resulting image to an external apparatus. As a result, a reception side can execute an optimum processing operation with respect to the synthesized image with reference to the attribute added to the image. As a consequence, even in a “network copy”, the “N-up” function can be realized in a high image quality similar to that of a “direct copy”.
