  • Patent number: 7717532
    Abstract: An imaging system that forms an image on a receiving medium including a fluid ejector that ejects fluid onto the receiving medium and a controller that controls the fluid ejector to eject the fluid to include a non-white and non-clear fluid or one of at least white and clear W fluid on each pixel on the receiving medium. A substantially single layer of fluid is ejected onto the receiving medium. A method for forming an image on a receiving medium includes ejecting a fluid onto the receiving medium, and controlling the ejection of the fluid to include a non-white and non-clear fluid or one of at least white and clear fluid for each pixel on the receiving medium.

  • Patent number: 7719698
    Abstract: Such a displaying device that can be easily operated by aged persons and handicapped persons, and an image forming apparatus using the same will be provided. Upon continuously operating an upper button for the predetermined period of time, a set value of a magnification is changed at intervals of numeric change that are different from each other between a voice guide mode activated by a voice guide button and a normal mode. At this time, it is configured in such a manner that the interval of numeric change for the normal mode is smaller than the interval of numeric change for the voice guide mode, i.e., the changing rate of the set value of the magnification for the normal mode is larger than that for the voice guide mode.

  • Patent number: 7720848
    Abstract: A probabilistic clustering system is defined at least in part by probabilistic model parameters indicative of word counts, ratios, or frequencies characterizing classes of the clustering system. An association of one or more documents in the probabilistic clustering system is changed from one or more source classes to one or more destination classes. Probabilistic model parameters characterizing classes affected by the changed association are locally updated without updating probabilistic model parameters characterizing classes not affected by the changed association.

  • Patent number: 7719718
    Abstract: A device and method is provided for breaking up undesirable patterns in vector error diffusion when the sum of inputs is near fraction values of the total input range. In the method, the value of the sum is calculated modulo the maximum input value. The mod value tendency to produce limit cycles is then determined for multiple planes in a manner similar to that for an individual plane. The threshold process for the vector calculation can then be modified to break up the cycles that occur in the combinations of the multiple colors. Typically, the largest of the individual plane modifications and the vector sum mod value is used for threshold modification. At least two different types of threshold modifications are possible: (1) random or psuedo-random noise address to the threshold; and (2) non-contiguous regions of threshold.

  • Patent number: 7719719
    Abstract: Images that include halftone structures are sharpened. A copy of received halftone image data is blurred, thereby reducing a detectability of edges of the halftone structures. Edges remaining in the blurred image data are detected. An edge enhancement image is generated based on the detected edges. The original received halftone image data is combined with the edge enhancement image, thereby generating sharpness enhanced image data having halftone structures. The sharpness enhanced image data having halftone structures can be rendered through a halftone screen that is compatible with a halftone screen that was used to generate the originally received image data. Alternatively, the sharpness enhanced image data having halftone structures is rendered according to error diffusion techniques, such as, rank order error diffusion in order to achieve or maintain dot or halftone structure compaction.

  • Patent number: 7719716
    Abstract: Colors similar to those which would be used in calibrating a target printer are printed on a printer of the same model and with the same materials set as anticipated for the printer calibration. These all lie within a substantially reduced portion of the gamuts of both the printer and scanner. A scanner characterization is derived only for those portions of color space corresponding to the printed colors. This may be done using spline fitting in one or more dimensions. While generic scanner calibrations generally have errors in excess of ?E=7, with these techniques values generally less than 1.7 were obtained. This is sufficient for printer calibration.

  • Patent number: 7719725
    Abstract: A print control apparatus includes a print request receiving unit and a print control unit. The print request receiving unit receives a print request, including print target information, to a print apparatus. If a condition is satisfied under which print target information should have information regarding security added thereto for printing, the print control unit adds the information regarding security to the print target information and causes the print apparatus to print the print target information to which the information regarding security is added. If the condition is not satisfied, the print control apparatus stores the print target information included in the print request in a storage unit, and when an operation receiving unit provided in the print apparatus is operated to instruct to print the stored print target information, the print control apparatus causes the print apparatus to print the stored print target information.

  • Publication number: 20100121822
    Abstract: A job log collection unit cooperates with job log management programs of copying machines to collect job logs held in the copying machines and store the collected job logs in a job log storage unit. A user change history creation unit refers to a human resource database to thereby determine whether a section which each user belongs to has been changed or not in a range of newly collected job logs. The user change history creation unit creates a user change history for each user who has encountered the change and stores the user change history in a user change history storage unit. A job log aggregation unit classifies the job logs of the job log storage unit into user sections by referring to the user change history of the user change history storage unit and aggregates the job logs in accordance with each section.
