A method and system for a portable device to obtain print data using a print device has steps of the portable device communicating a reference corresponding to the print data to the print device, with the reference comprising at least a location corresponding to the print data. The print device then communicates with the location to obtain the print data. Preferably, the portable device communicates with the print device via a wireless communications link.

Print by reference communication methods for portable wireless device printing

Pervasive output capability is provided so that an information apparatus can pervasively output digital content to an output device regardless of the processing power, display screen size and memory space of the information apparatus. This allows small mobile devices with limited display, processing power, and memory to be able to output a digital document (e.g., PDF, HTML, PowerPoint etc) in its full original richness, without resorting to downsizing, truncating, reducing, clipping or otherwise altering the original document. A data output system for rendering at an output device output content managed from an information apparatus may include means for obtaining a document object relating to the output content managed from the information apparatus and means for obtaining an output device object with one or more attributes corresponding to the output device. The document object and the output device object may be provided to a server application that is operated on a server that is distinct from the information apparatus and the output device and that generates output data employing at least partly the document object and the output device object. The output data is then provided to the output device for rendering the output content.

An image forming apparatus, method and system are disclosed, for acquiring a store document in the image forming apparatus and generating access authentication information. - The image forming apparatus can operate without wasteful use of resources thereof and unnecessary authentication. In the image forming apparatus, in response to an authentication request for a stored document therein from an external network device, first session information of a first session established within the image forming apparatus is acquired, the first session information is associated with second session information of a second session established between the network device and the image forming apparatus, and the second session information is sent to the network device. Then , in response to receipt of a predetermined process request using the second- session information from te network device, the first session information corresponding to the second session information is identified, and the first session information is used to fulfill the predetermined process request on the stored document.

A print service, preferably realized as a web site or part of web site, supports print by reference operations. Software hosted or accessible by the web site performs the required functions. A print client may be a print device, for example, that has an Internet connection. A print client might also be a portable wireless device, for example, which then might transfer data transcoded by the print service to a print device. The protocol and operational structure of the interface to the remote print service facilitate these operations. In general, the interface formed by the protocol carried out by the remote print service should provide for access by many clients. The interface must carry out a basic level of reference resolution and should provide enhanced print by reference features for clients capable of taking full advantage of the print service through use of a protocol of the invention. The print service, using the protocol, accepts a reference to print content, resolves the reference, obtains the print content, transcodes the print content into a print device ready format, and allows the print client access to the transcoded print data. The print service method realized by such a web site provides commercial potential for web services and content provider partnerships, as a preferred use of the print service might commence with a user of a portable wireless device obtaining a reference to print content while web surfing, communicating that content, for example via a Bluetooth wireless connection to the print device, which then uses the print service to resolve and process the print by reference communication. Similar commercial potential is possible with respect to print device manufacturers and the manufacturers of portable wireless devices, such as personal digital assistant (PDA) devices.

Print by reference service communication protocol and interface

A method for network printing. The method includes activating an interface between a document processing device and a workstation, providing at least one user interface to a user at the workstation. The interface allows the user to select operational settings for the document-processing device. The system then generates a document data file in accordance with the operational settings and communicates a location of the document data file and any auxiliary information to the document-processing device. This activates a document-processing job. The interface then receives a completion message upon completion of the document-processing job.

The picture processing device of the present invention improves the clarity without trimming or varying the color saturation. The picture processing apparatus of the present invention has pixel judgment means and pixel correction means. The pixel judgment means comprises target pixel detection means for detecting a target pixel having a peak level out of the input picture signal, and edge detection means for detecting edges, each presenting at a distance of n pixels (n >= 1) preceding and succeeding the target pixel. Furthermore, the pixel correction means has correction coefficient selection means wherein a peak level correction coefficient is selected according to an output from the target pixel detection means, and an edge correction coefficient is selected according to an edge detection output. With the picture processing apparatus of the present invention, a level of the target pixel is corrected and an edge of the input picture signal is corrected with the pixels of the input picture signal being corrected according to the peak level correction coefficient and the edge correction coefficient. The image pattern selection correction coefficient can prevent over-correction, so it is not necessary to trim the edge or vary the color saturation for improving the clarity.

PURPOSE:To perform optimum noise prevention following the period of a vertical synchronizing signal by discriminating the period of the vertical synchronizing signal to be inputted, and changing the width of an input inhibition band for noise masking according to this discriminated result. CONSTITUTION:A vertical counter 7 counts a clock pulse CK to be supplied to a clock input terminal C for a period nearly equal to a vertical scanning period, and is reset by the vertical synchronizing signal Vs from an external part, and an input inhibition circuit 2 masks the prescribed section of an external input vertical synchronizing signal Vsync in the input inhibition band, and supplies it as reset input to the vertical counter 7. Then, the plural kinds of the periods of the external input vertical synchronizing signal Vsync are discriminated according to plural pieces of count value timings to be caused as following the count increase of the vertical counter 7, and the width of the input inhibition band is switched according to this discriminated result. Thus, the best noise removing effect following synchronism alteration can be obtained.
