  • Patent number: 7952739
    Abstract: Version information set at a client terminal apparatus (110) is received. Identification data and print data generated at the client terminal apparatus (110) based on a file set at the client terminal apparatus (110) are received. Identification data of the file of the version indicated by the version information received from the client terminal apparatus (110) is acquired from a document management server (120). If the acquired identification data matches the received identification data, a print process is executed by using the received print data. Otherwise, a file corresponding to the acquired identification data is acquired from the document management server (120), and a print process is executed by using print data based on the acquired file.

  • Publication number: 20090297025
    Abstract: An image processing device corrects brightness/hue in appearance of an object of interest while suppressing an effect of an optical illusion even if the object of interest is overlapped with a background part of any color. The image processing device includes an evaluation device that evaluates a record value of the object of interest and the background part thereof, a device that corrects the record value of the object of interest in order to correct the optical illusion of a human being according to a result of evaluation by the evaluation device, and a device that performs record with the record value after the correction.

  • Publication number: 20080151307
    Abstract: A print processing device comprises: a storage to store an input print job including image data of plural pages; a print processor to perform printing to plural papers based on the image data of the plural pages; an image reader to acquire the image data for each page of the plural printed papers; a determiner to determine whether a print state for each page is good or bad, by comparing the acquired image data for each page with stored corresponding image data; and a controller to control, if the print state for a specific page is bad, the print processor to perform reprinting based on the image data of the specific page and the image reader to stand by for reading of a subsequent page until the reprinting ends, thereby enabling to easily replace, in the reprinting for a page of bad print state, this page with the reprinted page.

  • Patent number: 6556822
    Abstract: A digital cordless telephone device for performing radio communication with another telephone device via one of a plurality of base stations and executing a hand-over between a first base station to a second base station based on the RSSI of the first base station. The digital cordless telephone device includes an RSSI detection unit for detecting the RSSI of the first base station, a comparison unit for comparing the RSSI detected by the RSSI detection unit with a predetermined threshold, a connection control unit for trying to execute a hand-over when the RSSI is smaller than the predetermined threshold, a measurement unit for counting the number of continuous hand-over failures, and an information unit for giving a warning to the user of the digital cordless telephone device when the number counted by the measurement unit has reached the predetermined threshold.

  • Patent number: 6507407
    Abstract: An information processing apparatus and method are provided for controlling a printer. The apparatus comprises a first determination device for determining whether character pattern data representing a pattern of a character can be downloaded to the printer, and a download device for downloading the character pattern data to the printer in a case where the first determination device determines that a download is possible. The apparatus also comprises a first transmission device for transmitting a character code to the printer in a case where character pattern data is downloaded to the printer by the download device, an acquisition device for acquiring image information corresponding to the character in a case where character pattern data for a character is not downloaded by the download device, and a second transmission device for transmitting the acquired image information to the printer.

  • Patent number: 6373287
    Abstract: An input/output control circuit includes an input/output terminal, a first and second transistors configuring a CMOS circuit, a third transistor for carrying out a pull-up operation, an input control gate, an output control gate, a direction register for determining the direction of input/output direction, a control register for determining the mode of input or output, and a selection circuit connected to the gates for the first, second and third transistors, to the control terminals for the control gates, to the control register and also to the direction register. Since there is no redundant registers in this circuit construction, the whole size of the circuit can be made small, resulting in a reduction of total cost.

  • Patent number: 5524198
    Abstract: Using the character processing method having a plurality of processing schemes, character patterns are outputted in a plurality of windows using any of the processing schemes. The requirements of each window are discriminated, a processing scheme suited to a particular window is selected from the plurality of processing schemes in response to the requirements, and a character or graphic processed by the processing scheme selected for the window is outputted for each and every window.
