  • Publication number: 20050271296
    Abstract: Input image data is divided into a plurality of blocks. The skew angle of each divided block with respect to a predetermined direction is detected. Image data input from an input unit is converted into vector data for each divided block. The vector data corresponding to the divided block is corrected on the basis of the detected skew angle of each block.

  • Publication number: 20050123209
    Abstract: There are provided an image processing system and image processing method which can appropriately set whether to convert an original paper document into re-usable vector data before obtaining vector data from the paper document. An image scanning unit (110) scans a document to obtain image information, and a storage device (111) stores the image information. A data processing device (115) detects control information appended to the document from the image information and determines whether vectorization of the image information is permitted or inhibited. If the data processing device (115) determines that vectorization is permitted, it converts the image information into vector data; otherwise, it directly stores the image information in the storage device (111).

  • Publication number: 20050111052
    Abstract: An electronic file corresponding to a scanned original image is specified on the basis of the original image. If the electronic file corresponding to the original image cannot be specified, the original image is converted into vector data. The vector data is converted into image data. The first image data of the original image is compared with the second image data generated by the second conversion unit. On the basis of the comparison result, the first image data or vector data is selected as the electronic file corresponding to the original image.

  • Publication number: 20050111745
    Abstract: An image processing apparatus includes: a reading unit adapted to read an image and to generate image data representing the image; a separating unit adapted to separate the image data obtained by the reading unit into a plurality of objects corresponding to attributes; a selecting unit adapted to select a predetermined attribute of the image; a vectorization unit adapted to perform a vector conversion process for the image data separated by the separating unit in accordance with the predetermined attribute selected by the selecting unit; and an output unit adapted to output the image data processed by the vectorization unit.

  • Publication number: 20050111053
    Abstract: Vector data corresponding to a scanned original image is generated. An edit image of the original image corresponding to the display resolution of a display is generated on the basis of the vector data, and display of the edit image on the display is controlled.

  • Publication number: 20050068331
    Abstract: An image processing system and method includes selecting a color desired by a user, extracting a partial image corresponding to the color desired by the user and selected from a bit-map image, converting the partial image into vector data, storing the vector data in a memory, and setting the converted vector data as vector data to be processed as desired by the user. The image processing system and method further includes calculating a palette color from the bit-map image, extracting a partial image corresponding to the palette color, converting the partial image into vector data per color object, storing the vector data in a memory, and setting, as vector data to be processed as desired by the user, vector data per object that is selected from the vector data stored in the memory based on the color selected from the calculated palette colors.

  • Patent number: 5790165
    Abstract: In an image determination unit, a possibility that a read image is a predetermined image which is prohibited from an image formation is determined. If the possibility exists, an operation of the image formation is interrupted and whether or not the pertinent image is a predetermined image is determined based on the image information which is continuously inputted. If it is determined that the input image is a specific original, the image formation is suspended, while if not, the image formation processing is restarted.

  • Patent number: 5418602
    Abstract: A discriminating circuit discriminates the degree of similarity between an image represented by an input image signal and a predetermined specific image. A CPU outputs a pattern-level selecting signal based upon the results of discrimination performed by the discriminating circuit. A pattern adding circuit modulates an internally stored specific pattern in accordance with an added-color designating signal and pattern-level selecting signal produced by the CPU, and adds the modulated specific pattern to the image signal. As a result, a pattern specific to the apparatus is added in a reliably identifiable manner to an image output having a high probability of containing the specific original. In the case of an image output having a low probability of containing the specific original, the specific pattern is added to this image output in such a manner that the picture quality thereof is not diminished by the added pattern.
