摘要:
An original image comprises a printed region on which a predetermined printed matter is realized and a background region on which no printed matter is realized. The shape of a peripheral zone in the original image comprises the shape of the background region, which shape exists particularly at the peripheral region of said original image. It is determined whether or not the original image comprises the special document by detecting the peripheral zone. Further, the original image has an outer-frame region, having a predetermined shape, at the peripheral region of the original image. The determination is carried out using a result of measuring the width of the outer-frame region. Further, the width of the outer-frame region comprises a width along a direction substantially perpendicular to a direction extending along the outline of the original image.

An image forming apparatus including an image reading unit for reading an original and for outputting image data corresponding to the original, an image processing unit for processing the image data supplied from the image reading unit in accordance with a predetermined method and for outputting printing image data, a printer unit for printing an image corresponding to the printing image data supplied from the image processing unit, and an image adding unit for adding an identification information to the recording sheet on which the image is formed by the printer unit, the identification information identifying the image forming apparatus in order to prevent forgery of securities, confidential documents or backnotes. A detector detects the presence or absence of the image adding unit and disables the copying functions when the image adding unit is absent.

The present invention relates to a special-document discriminating apparatus used for providing a counterfeit preventing function to a digital copy machine and the like, and to a managing system for an image forming apparatus having a special-document discriminating function. The special-document discriminating apparatus is provided with a ROM for discriminating a special-document such as paper money, which ROM is detachably attached to a controlling circuit board. Data used for determination may be learned from test pattern data input from the image forming apparatus, or the data may be input from an external unit via a communication line. The managing system for an image forming apparatus comprises an image forming apparatus and a managing apparatus connected to the image forming apparatus. Either the image forming apparatus or the managing apparatus has a special-document discriminating function. Additional information is sent from the image forming apparatus together with determination result information or detected data. Information used as reference for determination may be sent from the managing apparatus to the image forming apparatus.

摘要:
An image recorder for converting input bilevel image data to multilevel data, executing various kinds of image processing with the mutlilevel data, and then recording the processed multilevel data. The image recorder converts input bilevel image data to M-level data (M being equal to or greater than 2), then requantized to N-level data, and then fed to a printer capable of recording data in three or more levels. The bilevel-to-multilevel conversion is effected in matching relation to the pattern of the input bilevel data. A plurality of bilevel-to-multilevel conversion means of different kinds are provided. The bilevel-to-multilevel conversion system is changed on the basis of the kind of input bilevel data. The M-level data is subjected to edge enhancement, magnification change, and gamma correction. Color image data produced by color separation are processed color by color and then fed to a printer.
摘要:
When image data is determined to be reused, a first image-data processing unit performs a first image processing on the image data, a memory device accumulates the image data on which the first image processing is performed, and a second image-data processing unit performs second image processing on the image data accumulated in the memory device. When the image data is determined not to be reused, the first image-data processing unit performs a first image processing, and the second image-data processing unit performs a second image processing on the image data on which the first image processing is performed.
摘要:
An image processing apparatus in which the reusability of digital image data is improved is disclosed. The apparatus includes an image reading unit reading a draft and obtaining the digitized image data; an image writing unit printing image data on a transfer paper; a recording unit recording image data and attached information of the image data; an external I/F unit transmitting and receiving image data and attached information of the image data; a first and a second image data processing units processing the image data from the image reading unit and the recording unit, respectively; and a bus controlling unit connecting each of the units. The first and the second image data processing units match the characteristics of the image data to prescribed characteristics so that the matched image data can be usable for both the image writing unit and the external device.
