摘要： An image can be formed by using a developer containing a luminescent substance, without impairing the finish of the area in which the image is formed. An image forming device 100 includes a print function section 124 which forms a first image included in a plurality of images to be formed on a single page, based on image formation data indicating the image to be formed, on a medium by using a first developer, and forms a second image included in the plurality of images, based on the image formation data, in a non-image-forming area in which the first image is not formed on the medium, by using a second developer containing a luminescent substance.

摘要： An information storage apparatus including a storage unit is configured to store an encrypted content and a corresponding decryption key. The storage unit includes a protected area to which access restrictions are set and in which a converted decryption key acquired through conversion of the decryption key is stored. The storage unit also includes a general-purpose area storing the encrypted content and a corresponding encrypted content signature file containing, as a recorded data item, a block identifier indicating the areas in the protected area where storage of the converted decryption key is permitted, in order to enable a reproducing apparatus which is configured to read the encrypted content from the storage unit and execute a reproducing process to determine whether content reproduction is permitted by applying the block identifier.

摘要： A density signal value determination method, an image forming apparatus, and an image processing system are configured to automatically and optimally determine the density of a copy-forgery-inhibited pattern image that includes a latent image and a background image. In a density signal value determination method, a test sheet, on which a plurality of latent image patches and a plurality of background image patches are formed, is outputted. Subsequently, the luminance, the density, and the reflection density of each of the patches are obtained from image data obtained by reading this test sheet. Then, an optimal combination of a latent image patch and a background image patch is selected according to the obtained values. Finally, density signal values used to generate the selected patches are set to generate a latent image and a background image.

摘要： There are at least four patterns of mounting the original on which an original image including a predetermined image marking "SECRET" indicating the content is confidential information, in an original mounting unit such as anADF. The image processing apparatus generates image data expressing the image depending on the original mounted state, and four pattern images are obtained depending on the direction of mounting the original. Of the plural original mounted states corresponding to plural layout states such as position or direction of the predetermined image, the predetermined mounted state of the original permitting image processing is preliminarily noticed to an authorized user, and image processing is prohibited when the layout state of the predetermined image corresponding to other mounted state than the predetermined mounted state is given, so that image processing by unauthorized user can be prevented.

摘要： The present invention relates to the segmentation of an image into a main area and a image segment for variable data differential gloss image control. A single color is selected. Two or more different color definitions are created by combining the selected single color with two or more halftones having anisotropic structure characteristics which are significantly different in orientation to each other while remaining identical in density. By alternatively assigning the color definitions to the image segment in accord with the variable data content, a variable data differential gloss image may be superimposed within an image having reduced data processing and storage requirements.

摘要： A watermark information embedding apparatus capable of embedding a plurality of different types of information together in a document is provided. In a pattern table 19, (1) a permanent dot pattern which is to remain after a document is copied and (2) a temporary dot pattern which is to be erased as the document is copied, are both allocated to each of symbols constituting confidential information and they are classified and managed as hyper-complex matrices. A watermark image is formed based upon anti-copy information used to determine whether the permanent dot pattern or the temporary dot pattern is to be set. Since this allows both the anti-copy information and the confidential information to be embedded together in the document, duplication of the document containing the confidential information embedded therein can be deterred.
