A data management system includes an authentication server and a data management apparatus (or an MFP). The authentication server includes a storage part for storing affiliation information specifying at least one group that each user belongs to, an authentication part for transferring and receiving data to and from the data management apparatus to perform user authentication, and a group identification part for identifying one or more groups that an authenticated user belongs to based on the affiliation information to send information about the one or more groups to the data management apparatus. An access permission part of the data management apparatus permits an authenticated user belonging to a plurality of groups to access a data file to which any of the plurality of groups has been granted access.

Image distortion is corrected in a color printer wherein print units for a plurality of colors are aligned to form a color image by superposing images formed by the print units. A quantity of image distortion is detected, and correction data of main scan address and subscan address are calculated and stored according to the detected image distortion for each main scan address. When input color image data are corrected, printing position is corrected in combination of address change with density interpolation. When the correction data exceeds the maximum correction range, the correction data are replaced by the maximum in the correction range for distortion correction. Further, in the image data correction, after the image data are converted to data having a smaller number of gradation levels, the data are delayed according to the serial arrangement of the print units. Then, the delayed data are converted again for printing.

A quantity of image distortion is detected, and correction data of main scan address and subscan address are calculated and stored according to the detected image distortion for each main scan address. When input color image data are corrected, printing position is corrected in combination of address change with density interpolation. When the correction data exceeds the maximum correction range, the correction data are replaced by the maximum in the correction range to utilize the capability of the distortion correction of the printer. Further, in the image data correction, after the image data are converted to data having a smaller number of gradation levels, the data are delayed according to the serial arrangement of the print units. Then, the delayed data are converted again for printing.
摘要:
In an image processor, after the background of input image data is removed, the image data are divided into a plurality of areas, and the attribute of image is discriminated for each area. The image data after the background removal is compressed according to the result of attribute discrimination. The amount of the background removal can be controlled. Preferably, the amount of the background removal is controlled according to the discriminated attribute. Then, the background can be removed without artificial feeling in a reproduced image.

An image editing apparatus used as a film scanner for reading the image of a photo film and outputting an image signal has a display unit for displaying an input image on its picture frame and can output image signals for showing all or a part of the input image on a plurality of paper sheets. An image editing apparatus can display on the picture frame of the display unit, the image of the sheet and an image representing the position of an image to be stored onto the sheet.

In an image processor capable of setting operation modes separately for a plurality of items related to image processing, it can be designated whether or not to reset the operation mode of each item to an initial mode. The designated data is stored in a resetting/not resetting memory. In the apparatus, when a batch reset processing is instructed, only an item authorized to be reset according to the data stored in the memory is reset to the initial mode. As a result, even if the batch reset instruction is executed, a desired operation mode is not reset.

An image forming apparatus having replaceable or exhaustible component parts is provided with a security system to determine the authenticity and remaining service life of the component parts. The component part can be provided with an identifiable code, for example, stored in a RAM that can be checked with predetermined identification codes in a computer system in the image forming apparatus. Verification of the authenticity of the replaceable component part can govern the operation of the copying apparatus. The component part, for example, can be provided with a manufacturer code and a confidential identity code. This manufacturer code can be compared with the stored manufacturer code, and a determination can be made as to whether the product is authentic and the remaining useful life of the product. If the product is not authentic, the copying apparatus can be disabled. Also, if the product has been rebuilt or has come to the end of its useful life, the copying apparatus can be disabled.
摘要:
An image scanning device includes a first scanner scanning a top side of a transported document at a first scanning position to obtain a first scanned image, a second scanner scanning the back side of the transported document at a second scanning position to obtain a second scanned image, a document feeder transporting a document at the second scanning position at a speed differing from the transportation speed at the first scanning position, and a controller controlling the image scanning device. The controller sets, as a scanning form of a document, either one-side scanning of scanning one side of a document through one transportation, or dual-side scanning of scanning both sides of a document through one transportation. The controller also obtains a set magnification. The controller determines the transportation speed by the document feeder such that, when one-side scanning is set, the scanning magnification in a first direction corresponding to the document transportation direction at the first scanned image attains the set magnification, and when dual-side scanning is set, the scanning magnification in the first direction at the second scanned image attains the set magnification.
摘要:
An MFP sequentially displays a plurality of operation screens on a display panel by switching, and receives a user operation on each operation screen. The user operation is performed for the switching or execution of a function, and the operation screens include screens customized by a user. A guidance information providing device includes: an information storage part storing switching information pieces in correspondence with the customized screens; a route generator that generates route information with reference to the stored switching information pieces, the generated route information indicating a display order of customized screens to be sequentially displayed between a current customized screen and a desired customized screen; a controller that selects, from among the stored switching information pieces, a switching information piece indicating switching from the current customized screen to a next customized screen to be displayed according to the display order indicated by the generated route information; a guidance generator that generates guidance information indicating an operation method for the user to switch the current customized screen to the next customized screen; and a communicator that outputs the generated guidance information.
