Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information processing system, a data transfer method, a data transfer program, and a data transfer method for transferring data between a first information device that displays image data and a second information device that can receive and display the image data. The present invention relates to a recording medium on which a data transfer program is recorded.
[0002]
[Prior art]
When operating data used in an information device such as a personal computer with an information device such as a PDA (Personal Digital Assistant) that operates on a system different from the previous information device, the data to be shared is stored on each information device. If the data is directly operable, the purpose can be achieved by transmitting the data itself.
[0003]
For example, when a hypertext is directly operated on a personal computer, if a program capable of directly operating the hypertext is installed on the PDA, the hypertext can be directly operated on the PDA. The goal can be achieved by sending hypertext to
[0004]
In such a situation, some programs on the information equipment of the transmission source can convert the data into data that can be handled by the information equipment of the transmission destination and save the converted data.
[0005]
For example, if there is a program for converting hypertext to image data on a personal computer and a program for displaying image data on a PDA, then convert the hypertext to image data on the personal computer and send it to the PDA. By doing so, the object can be achieved even when the PDA cannot directly operate the hypertext.
[0006]
Meanwhile, in recent information devices, an information processing system in which a PDA is linked with another information device for the purpose of printing a print image has been proposed (for example, see Patent Document 1).
[0007]
This information processing system includes a PDA capable of wireless communication with a home server and a printer for performing printing based on print image data from the PDA. When a data file on the home server is selected, the PDA is transmitted to the home server. The home server instructs the format of the print image data, and converts the data file into the specified format and transmits the data file to the PDA. The PDA outputs the transmitted print image data to a printer without passing through an internal memory.
[0008]

[0009]
[Problems to be solved by the invention]
Here, the data handled in this specification is classified into two types of data. That is, data that can be operated in the same way with image data on the screen display (hereinafter referred to as “basic data”), and data that is important for a very small number of programs but meaningful for other programs Data (hereinafter referred to as “application data”). In this case, in order to share application data between information devices operating in different systems, it is necessary that one of the information devices corresponds to the application data. For example, a process of introducing a program corresponding to application data into each information device and a process of converting the data into basic data on the information device corresponding to application data are required. That is, unless such special processing is performed, it is impossible to operate the application data.
[0010]
Further, in Patent Document 1, the PDA is treated as a kind of relay device, and there is a problem that the print image data transmitted from the home server cannot be displayed or operated on the PDA. . Also, a mechanism and means for printing were required. Furthermore, in the current situation in which the screen of the PDA has become increasingly fine, the necessity to print out the print image data transmitted from the home server has been reduced, which is against resource saving. There was also.
[0011]
SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and an object of the present invention is to provide information capable of reliably transferring data of a plurality of pages or image data which cannot be seen unless the screen is scrolled by a simple operation. An object of the present invention is to provide a processing system, a data transfer method, a data transfer program, and a recording medium on which the data transfer program is recorded.
[0012]
[Means for Solving the Problems]
An information processing system according to the present invention is an information processing system that connects a first information device that displays image data and a second information device that can receive and display image data to transfer data. The first information device includes a data transfer unit that transfers print image data of an application in the device to the second information device. It is provided with a data receiving means for receiving the transferred print image data, wherein the second information device can operate the received print image data.
[0013]
According to the present invention having such features, by transferring print image data to the second information device by communication as a print driver of an application, data of a plurality of pages or a screen cannot be seen unless scrolled. Such image data can be reliably transferred by a simple operation.
[0014]
In this case, as a transfer method, a method of transferring the print image data by file transfer, or a method of transferring the print image data after recognizing the storage devices of the first information device and the second information device as pseudo storage devices with each other. There are various ways to do this. When transferring the print image data after recognizing the storage devices of the first information device and the second information device as pseudo storage devices, the second information device is connected to one drive of the first information device (for example, D drive, etc.), and by selecting this D drive, it becomes possible to transfer (copy) the print image data to the second information device. Alternatively, displaying the first information device as one drive of the second information device may be similarly considered.
[0015]
In addition, the first information device may perform color correction according to a display format of a display device of the second information device when the print image data is created, and then transfer the print image data. That is, the method of reproducing the image differs depending on the display format of the display device. For example, in the case where the display device is a reflective liquid crystal mounted on a PDA as the second information device, a beautiful color is displayed when displayed on the PDA due to the relationship between the reflectance and the base color of the liquid crystal. Color correction is performed when print image data is created. Further, when outputting to a projector via a PDA, correction is similarly performed in accordance with the color characteristics of the transmitted light of the liquid crystal used in the projector. This makes it possible to display the print image data in an optimal color according to the display format (structure) of the display device.
[0016]
In addition, the first information device may reduce the file size by performing color reduction or black-and-white conversion when creating the print image data before transferring. For example, if the display device has 256 display colors, the print image data to be created is also created in 256 colors. Also, if the print image data is a presentation in a normal document, even if it is converted from color to black and white, the print image data hardly changes in terms of readability. Create by converting to black and white. By reducing the file size in this manner, the data transfer speed is increased, and the data amount becomes easy to handle in the second information device.
[0017]
In addition, the first information device may transfer the image data to a screen size that is easy to display on the second information device when creating the print image data. When the second information device is a PDA that is a portable information terminal, the size of the display screen is naturally limited. Transferring a large amount of print image data of one page to a PDA whose screen size is limited as described above causes a problem that the entire page cannot be viewed unless the screen is scrolled many times. Therefore, by unifying the screen size (for example, VGA size, which is a display standard, for example) that can be easily displayed on the PDA, the PDA can be displayed on the PDA without being affected by the image size of each page of the transferred print image data. An easy-to-view screen can be displayed.
[0018]
Further, the first information device may create and transfer print image data in accordance with an image size handled by the second information device when creating the print image data. That is, when creating print image data, instead of creating print image data according to a normal paper size (A4, B4, A5, B5, postcard, etc.), a VGA, The screen image data is created in a size such as SVGA or XVGA. Thereby, display suitable for the display size of the PDA can be performed.
[0019]
In addition, the second information device transmits information on its own display capability to the first information device during connection communication with the first information device, and the first information device transmits the second information device to the second information device. The image size of the print image data to be created may be determined based on the display capability information received from the information device. Here, the information of the display capability includes a screen size, a dot pitch, a color depth, a refresh rate, a color characteristic, and the like. By transmitting the display capability of the second information device in advance before creating the print image data, the user can perform the operation of the second information device without performing a troublesome operation such as setting the image size. It is possible to automatically create print image data of a size suitable for the display size.
[0020]
Also, the first information device, when creating the print image data, rotates the print image to fit the display screen of the second information device based on a preset printing direction on the paper, and converts the data. You may make it a file. Depending on the user, vertically long data (such as a document) such as A4 portrait and B4 portrait is displayed on the second information device using a vertically long display screen, and horizontally long data such as A4 landscape and B4 landscape (table or graph) is displayed. , Etc.), there is a demand that the second information device also displays the display screen in landscape orientation. Therefore, in the present invention, for example, for vertically long data, print image data is created so that the display screen is displayed vertically, and for horizontally long data, the display image is displayed horizontally. The print image is rotated 90 degrees to create and transfer data. Thus, in the second information device, for example, vertically long data such as a document is displayed in a vertically long direction on a display screen, and horizontally long data such as a table or a graph is displayed in a horizontally long direction on a display screen.
[0021]
In the above case, the first information device may compress and transfer the print image data to, for example, JPEG, PNG, GIF, or the like.
[0022]
Note that the information processing system having the above configuration can be realized as a data transfer method for transferring data between the first information device and the second information device.
[0023]
That is, the data transfer method of the present invention is the data transfer method of transferring data between a first information device that displays image data and a second information device that can receive and display image data. Creating print image data of an application in a first information device, and transferring the created print image data to the second information device, wherein the print image data received by the second information device is Can be operated. In this case, in the transfer step, the print image data may be transferred by file transfer, or the print image data may be transferred after recognizing the storage devices of the first information device and the second information device as pseudo storage devices. It may be transferred.
[0024]
The step of creating the print image data may include a step of compressing the print image data, and may perform a color correction suitable for a display format of the display device of the second information device when creating the print image data. It may include a step of reducing the file size by performing color reduction or black and white conversion when creating the print image data. Furthermore, the step of creating the print image data may include a step of unifying the image size to be easily displayed on the second information device when creating the print image data, or the step of creating the print image data. And generating print image data in accordance with the image size of the information device.
[0025]
In addition, during the connection communication between the second information device and the first information device, the method includes a step of transmitting information of the display capability of the device itself from the second information device to the first information device, The step of creating the print image data may include a step of determining an image size of the print image data to be created based on the display capability information received from the second information device.
[0026]
Still further, in the print image data creating step, when the print image data is created, the print image is rotated to match the display screen of the second information device based on a preset printing direction on a sheet. May be included in a file.
[0027]
Further, the above-described data transfer method can be provided as a data transfer program for realizing this method, and can also be provided as a recording medium storing the data transfer program.
[0028]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0029]
FIG. 1 shows an embodiment of an information processing system for realizing a data transfer method according to the present invention, in which print image data of an application is transferred from a personal computer as a first information device to a PDA as a second information device. FIG. 2 is a functional block diagram schematically showing a system configuration for transferring the data.
[0030]
The personal computer includes a processing device 1 that converts data to be handled into a format that can be understood by humans, performs a process such as updating data in accordance with input information, an input device 2 such as a keyboard and a mouse that accepts user operations, an image, A display device 3 for presenting information such as sound to the user, a storage device 4 for storing data to be handled, data temporarily converted to information such as images and sound, and a device such as another personal computer or PDA. It comprises a connection device 5 for connecting via a connection medium such as the Internet or a USB cable, and a printing device 6 for printing and outputting data and the like stored in the storage device 4.
[0031]
The PDA includes a processing device 7 that performs a process requested according to a user operation, an input device 8 that receives an operation by the user, a display device 9 that displays information such as images and sounds to the user, and the like. The storage device 10 stores information received from a personal computer or PDA, or stores data temporarily converted internally, and a connection device 11 for connecting to another personal computer or PDA. As communication media, various forms such as USB, infrared communication (IRDA), wireless communication (Wireless), and LAN can be used.
[0032]
In this embodiment, on a personal computer equipped with Windows (registered trademark of Microsoft Corporation: the same applies hereinafter) as a specific example, a PDA is converted from a hypertext having information such as a figure, text, and a link indicating a reference to another document. The case of creating the data to be browsed above will be described with reference to the flowchart shown in FIG.
[0033]
When browsing data only with a personal computer, the processing device 1 interprets and executes a hypertext browsing program (hereinafter referred to as a browser) read from the storage device 4 or obtained from another device via the connection device 5.
[0034]
That is, an instruction from the user such as "print a display page" is obtained from the input device 2 (step S1).
[0035]
For example, by operating using the input device 2, hypertext stored in the storage device 4 based on an instruction from the user, or obtained from another device via the connection network such as the Internet from the connection device 5. The hypertext (see FIG. 3) is processed into print image data (step S2). The processed print image data is once passed to Windows and normally printed by the printing device 6.
[0036]
This operation may be, for example, an operation of pressing a key on a keyboard, an operation of pressing a button indicating transmission start using a pointing device such as a mouse, or any other operation. You may.
[0037]
In response to this operation, Windows passes the print image data in the requested range to the PDA transmission print driver (step S3). The PDA transmission print driver converts the received data into an image format (JPEG (Joint Photographic Experts Group), DIB (Device Independent Bitmap), or the like) for storage on the PDA (step S4), and transmits this to the PDA (step S4). Transfer) (step S5). As a transfer method, a method of transferring print image data by file transfer, a method of transferring (copying) print image data by a network drive, and the like can be considered.
[0038]
The network drive recognizes the storage devices of the first information device and the second information device as pseudo storage devices, and both storage devices recognize each other as a counterpart storage device.
[0039]
The PDA performs processing in accordance with processing determined in advance on the PDA, such as storing the received print image data in the storage device 10 or displaying the print image data on the display device 9 without storing the print image data.
[0040]
By executing such a series of processes, it is possible to convert the application data operated by the transmission source program into basic data and transmit it to the PDA without performing any special processing on the transmission source program. It is possible to display a hypertext even in a PDA that does not support the display of a hypertext as long as an image can be displayed.
[0041]
Next, a specific procedure for capturing print image data will be described with reference to the flowchart shown in FIG.
[0042]
First, a document to be captured as print image data is opened (step S11).
[0043]
Next, a pop-up menu shown in FIG. 5 is opened by clicking an icon on a task tray (not shown). In this pop-up menu, "Image capture (active window) (A)", "Image capture (rectangular area designation) (R)", "Print image capture (entire document) (D)" are available as image data capture methods. , "Text capture (T)", and here, "Print image capture (entire document) (D)" is selected (step S12). The selection method may be selected from this pop-up menu, but can also be selected by pressing “Ctrl” + “PrintScreen” button on the keyboard of the personal computer.
[0044]
Thereby, as shown in FIG. 6, a print dialog box of the application is displayed (step S13). Here, in the present embodiment, the name of the PDA is displayed as the printer name (printer driver) in the print dialog. That is, the PDA is displayed as one drive of a personal computer (in this embodiment, it is a D drive), and the D drive is selected. However, the printer name may be set to a default value so that it can correspond to actual printing, and the user may select PDA as the printer name.
[0045]
Thereafter, by confirming the printer name and pressing the "OK" button (step S14), the print image data of the displayed document of the active window is copied to the PDA image file (step S15).
[0046]
In the case where the data is not transferred (copied) as a network drive, but is transferred as a JPEG file, for example, the print image data is fetched in step S12 and then temporarily stored in the storage device 4 of the personal computer. Then, the connection status with the PDA is checked, and if the PDA is connected to the personal computer, the stored print image data is transmitted to the PDA as a JPEG file. In the case of JPEG, if information such as thumbnails is embedded in Exif format, thumbnail images of all pages of the print image data can be viewed on the PDA side.
[0047]
Here, when "property (P)" in the print dialog shown in FIG. 6 is selected, a property screen shown in FIG. 7 is displayed. On this screen, the user can arbitrarily set the resolution, paper size, printing direction (accurately, display direction) of data displayed on the PDA side, and the like. There are four resolutions available: low (72 dpi) / medium (96 dpi) / high (150 dpi) / high (300 dpi). There are seven types of postcards. FIG. 8 shows the relationship between the paper size and the output resolution.
[0048]
FIG. 9 shows a correspondence relationship (dot number comparison) between each size of VGA / SVGA / XGA / SXGA / UXGA, which is an image size of a display system, and each paper size. The user may set the paper size and resolution according to such correspondence. For example, when the A4 size print image data is to be displayed in the SVGA size on the PDA side, the paper size may be set to A4 and the resolution may be set to 72 dpi on the property screen shown in FIG. As a result, the number of dots in the A4 size with a resolution of 72 dpi becomes “horizontal: vertical = 855: 605”, which is almost the same as the number of dots in the SVGA size “horizontal: vertical = 800: 600”. The image is displayed in a size that can be almost fit on the display screen of the PDA.
[0049]
In the above process, the acquired print image data is transmitted to the PDA as it is, but the appearance of the display may differ depending on the display format of the display device on the PDA side. Therefore, when the print image data is created, the image data may be transferred after performing color correction that matches the display format of the display device on the PDA side.
[0050]
For example, when the display device 9 of the PDA is a reflection type liquid crystal, the color correction of the print image data is performed in consideration of the reflectance and the base color of the liquid crystal so that a beautiful color is displayed when displayed on the PDA. . When outputting to a projector via a PDA, color correction of print image data is performed in accordance with the color characteristics of the transmitted light of the liquid crystal used in the projector. Note that various specific methods of color correction have been proposed in the past, and these techniques can be used in the present embodiment, and therefore, detailed description is omitted here. As a result, the print image data can be displayed in an optimal color according to the display format of the display device 9 on the PDA side.
[0051]
As a method of selecting what kind of color correction is performed on the print image data, for example, a color correction selection screen (not shown) is displayed on a screen of a personal computer, and “PDA (reflective liquid crystal)”, “ Projector (transmissive liquid crystal) ". Then, when the user selects a name from the names, color correction of a display format corresponding to the name may be performed. For example, when it is desired to display print image data for presentation on a projector externally attached to the PDA, it is sufficient to select “projector” displayed on the color correction selection screen.
[0052]
When the amount of print image data is large, the file size may be reduced by performing color reduction or black-and-white conversion before transfer.
[0053]
For example, when the display color of the display device 9 is 256 colors, the print image data to be created is created not in full color but in 256 colors. Also, if the print image data is a presentation in a normal document, even if the image is converted from color to black and white, the print image data hardly changes in terms of legibility. Create by converting to black and white. By reducing the file size in this manner, the data transfer speed is increased, and the data amount becomes easy to handle even in a PDA.
[0054]
Further, when the print image data is created, the print image data may be transferred in a uniform size to be easily displayed on the PDA side.
[0055]
When the second information device is a PDA, the size of the display screen is naturally limited. If the print image data having a large capacity of one page is directly transferred to the PDA whose screen size is limited as described above, a problem occurs that the entire page cannot be seen unless the screen is scrolled many times. Therefore, by unifying the screen size (for example, VGA size, which is a display standard, for example) that can be easily displayed on the PDA, the PDA can be displayed on the PDA without being affected by the image size of each page of the transferred print image data. An easy-to-view screen can be displayed. FIG. 10 shows this example. FIG. 3A shows an example of print image data of a vertically long size, and FIG. 3B shows an example of print image data of a horizontally long size. When the data is transferred to the PDA, as shown in FIGS. 3C and 3D, these print image data are all transferred to the same size (for example, VGA (640 × 480)).
[0056]
Further, when the print image data is created, the print image data may be created and transmitted according to the image size of the PDA. That is, when the print image data is created, the print image data is not created according to the normal paper size (A4, B4, A5, B5, postcard, etc.), but is adjusted to the image size of a display system such as a PDA or a projector. Then, print image data is created in a size such as VGA, SVGA, or XVGA.
[0057]
FIG. 11 shows an example of a setting screen on which the user sets the image size of the print image data. FIG. 11A shows an example in which the image size is specified by specifying the magnification, and FIG. 10B shows an example in which the image size is set by selecting the image size of the display system.
[0058]
In the magnification specification of FIG. 7A, it is necessary for the user to remember the ratio between the paper size and the image size of the display system, so that setting may be difficult. On the other hand, in the case of FIG. 3B, the type of image size is displayed in advance, and it is considered that the user can set the desired image size by selecting one of them. In this case, display such as VGA, SVGA, and XGA can be performed as the image size. However, since these size displays are not generally known as paper sizes (A4, B4, B5, etc.), In the embodiment, it is represented by the number of horizontal and vertical dots. Incidentally, “640 × 480” corresponds to the VGA size, and “800 × 600” corresponds to the SVGA size. Other items are items for the user to manually input the number of horizontal dots and the number of vertical dots, and the XGA size is displayed as a default value in the figure (see FIG. 9 for numerical values). .
[0059]
Such a setting on the screen enables display suitable for the screen size of the PDA.
[0060]
In the above description, the user manually sets the image size of the print image data to be transmitted to the PDA. However, such image size setting can be automated.
[0061]
FIG. 12 shows a processing procedure for automatically setting the image size.
[0062]
The PDA and the personal computer are connected, for example, by USB, and the power of the PDA and the personal computer is turned on (step S21, step S31).
[0063]
When confirming that the PDA is connected to the personal computer (Yes in step S22), the PDA transmits information on its own display capability to the personal computer. The display capability information includes a screen size, a dot pitch, a color depth, a refresh rate, a color characteristic, and the like.
[0064]
FIG. 13 shows an example of the configuration of a display capability information packet transmitted to the personal computer. Following the header, data such as a PDA name, a screen size, a dot pitch, a color depth, a refresh rate, and a color specification are recorded, and an EOM is added last.
[0065]
The personal computer temporarily stores the display capability information transmitted from the PDA in the storage device 4 (step S32), and changes the image characteristics such as the image size of the print image data to be created based on the stored display capability information. It is determined (step S33).
[0066]
As described above, by transmitting the display capability of the PDA to the personal computer in advance at the time of connection, it is possible to set the image size suitable for the PDA screen size on the personal computer without the user having to perform a troublesome operation such as setting the image size. It is possible to automatically create print image data. In the case of wireless communication, the display capability of the PDA is transmitted to the personal computer in advance when communication becomes possible.
[0067]
Depending on the user, portrait data such as A4 portrait and B4 portrait (documents, etc.) are displayed on a PDA using a portrait screen, and landscape data such as A4 landscape, B4 landscape (tables, graphs, etc.) There is also a demand for using a screen in landscape orientation on a PDA.
[0068]
Therefore, in the present embodiment, print image data is created so that the PDA screen is displayed vertically using the PDA screen for vertically long data, and the PDA screen is displayed horizontally using the PDA screen for the horizontally long data. Data is created by rotating the print image by 90 degrees.
[0069]
That is, the print image data shown in FIG. 14A is sequentially scanned in the horizontal direction while moving from the upper left to the lower side, and the data is horizontally moved from the upper left to the lower side in the same manner on the VRAM of the storage device. Recording is performed sequentially (see FIG. 4B). When this data is transmitted to the PDA, the PDA displays the data shown in FIG. 3A in a vertically long state on a vertically long screen as it is (see FIG. 4C). On the other hand, the scan direction of the print image data shown in FIG. 14A is rotated by 90 degrees, sequentially scanned in the vertical direction while moving from the lower left to the right, and the data is similarly stored in the VRAM as a storage device from the lower left. Recording is performed sequentially in the vertical direction while moving to the right (see FIG. 4D). When this data is transmitted to the PDA, the PDA displays the data shown in FIG. 9A horizontally (ie, in a state where the display direction is rotated by 90 degrees) on a vertically long screen (FIG. e)).
[0070]
As a result, as shown in FIG. 15, in the PDA, for example, vertically long data such as a document is displayed in a vertically long display screen on the vertically long display screen (see FIG. 15A), and horizontally long data such as a table or a graph is vertically displayed. It is displayed on the screen in the horizontal direction (see FIG. 3B).
[0071]
By the way, if the vertically long data is configured to be displayed on the PDA using the screen in the portrait orientation, and the horizontally long data is configured to be displayed on the PDA using the screen in the landscape orientation, the user is required to display the data every time the data is displayed. The PDA itself must be rotated 90 degrees in accordance with the display state (vertical display or horizontal display). In addition, when viewing the display with the screen in landscape orientation, the button arrangement is also horizontal, as shown in FIG.
[0072]
FIG. 16 shows an embodiment for eliminating the inconvenience of rotating the PDA itself by hand and the inconvenience of button operation in the case of landscape display.
[0073]
That is, the PDA 51 is configured by a display unit main body 52 having a rectangular shape in a plan view and a holding body 53 holding the display unit main body 52, and the display unit main body 52 is rotatably held via a rotation mechanism (not shown). The structure held by the body 53 is adopted. In this case, various buttons are provided on the holder 53 side. An operation button 54 for rotating the display unit 52 is also provided on the holder 53. By pressing the operation button 54, the user changes from the vertically long screen state shown in FIG. 5A to the horizontally long screen state shown in FIG. The display unit main body 52 can be rotated from the state to the state of the vertically long screen shown in FIG. This eliminates the need for the user to rotate the PDA itself, and the button arrangement does not change with the rotation, thereby improving operability.
[0074]
In the above embodiment, the display unit main body 52 is rotated by the user's button operation. However, when the print image data is rotated by 90 degrees on the personal computer side, the rotation information is also included in the print image data. In addition, when the rotation information is transmitted to the PDA side and the PDA receives the rotation information, the display body 52 can be automatically rotated by 90 degrees. As described above, by automatically rotating the display unit main body 52 in accordance with the display mode of the created print image data, the user can always view in the most visible state without being conscious of the display mode such as portrait or landscape. You can see the contents of the display screen.
[0075]
Incidentally, it is possible to embed additional information in the print image data depending on the format. For example, in the case of JPEG, information can be embedded in an area called an application marker segment.
[0076]
Further, even when the data cannot be embedded, the same function can be realized by preparing another data and indicating that the data is additional information to the print image data.
