Description

[0001]
BACKGROUND OF THE INVENTION
The present invention transmits data between a first information device that is an information processing apparatus that displays image data, and the first information device and a second information device that can receive and display image data. You De The present invention relates to a data transmission method, a data transmission program, and a recording medium on which the data transmission program is recorded.
[0002]
[Prior art]
When data used on an information device such as a personal computer is operated on an information device such as a PDA (Personal Digital Assistant) that operates on a different system from the previous information device, the data to be shared is stored on each information device. In the case of data that can be directly operated on, the object 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 purpose can be achieved by sending hypertext to the.
[0004]
In such a situation, some programs on the transmission source information device can convert the data into data that can be handled by the transmission destination information device and save the data.
[0005]
For example, if there is a program that converts hypertext to image data on a personal computer and a program that displays image data on the PDA, the hypertext is converted to image data on the personal computer and then sent to the PDA. Thus, even if the PDA cannot directly operate the hypertext, the object can be achieved.
[0006]
By the way, in recent information devices, an information processing system in which a PDA is linked with other information devices 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 that performs printing based on print image data from the PDA. When a data file on the home server is selected, the PDA The home server instructs the format of the print image data, and converts the data file into the designated format and transmits it to the PDA. The PDA outputs the transmitted print image data to a printer without going through an internal memory.

[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 manipulated in the same way with image data on the screen display (hereinafter referred to as “basic data”) and an important meaning 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 to correspond to the application data in any of the information devices. For example, processing such as introducing a program corresponding to application data into each information device, or processing such as conversion to basic data on an information device corresponding to application data is required. In other words, it is impossible to manipulate application data unless such special processing is performed.
[0010]
In Patent Document 1, the PDA is handled as a kind of relay device, and print image data transmitted from the home server cannot be displayed or operated on the PDA. . Moreover, a mechanism and means for printing were also necessary. Furthermore, in the current situation where the screen of the PDA has become high definition, there is less need to print out the print image data transmitted from the home server, which is also contrary to resource saving. There was also.
[0011]
The present invention was devised to solve such problems, and its purpose is information that can reliably transmit data of a plurality of pages and image data that cannot be seen unless the screen is scrolled with a simple operation. Processing equipment , A data transmission method, a data transmission program, and a recording medium on which the data transmission program is recorded.
[0012]
[Means for Solving the Problems]
An information processing apparatus according to the present invention includes a storage unit that stores data handled by application software, a conversion unit that converts data stored in the storage unit into image data, and image data converted by the conversion unit. of Instruction means for instructing transmission to another information device, and transmission (transfer) means for transmitting (transferring) the converted image data to another information device according to the instruction of the instruction means. Yeah Yes. Also , Information processing system for transmitting data between first information device as information processing device for displaying image data and second information device as other information device capable of receiving and displaying image data The second information device includes receiving means for receiving the image data transmitted from the first information device, and displays the image data received by the second information device. Constitution It is said.
[0013]
According to the present invention having such characteristics, as a print driver for an application I By transferring the image data to the second information device by communication, multiple pages of data and image data that cannot be seen without scrolling the screen can be assured with a simple operation. Send can do.
[0014]
in this case, Send File as a way to Send Image data Send And the first information device and the storage device of the second information device are mutually recognized as pseudo storage devices. I Image data Send Possible ways to do this.

That is, I When creating image data, follow normal paper sizes (A4, B4, A5, B5, postcards, etc.) I Rather than creating image data, screen image data is created in a size such as VGA, SVGA, or XVGA in accordance with the image size handled by the PDA. As a result, display suitable for the display size of the PDA is possible.
[0019]
In addition, the second information device transmits information on its 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. Create based on display capability information received from other information devices I You may make it determine the image size of image data. Here, the display capability information includes screen size, dot pitch, color depth, refresh rate, color characteristics, and the like. I By transmitting the display capability of the second information device in advance before creating the image data, the display of the second information device can be performed without a troublesome operation such as setting the image size by the user. Suitable for size I Image data can be created automatically.
[0020]
In addition, the first information device has the I At the time of creating the image data, the print image may be rotated to fit the display screen of the second information device based on a preset printing direction with respect to the paper, and the data may be filed. Depending on the user, portrait data such as A4 portrait and B4 portrait (documents, etc.) is displayed on the second information device using the display screen in portrait orientation, and landscape data such as A4 landscape and B4 landscape (tables and graphs). There is a desire to display the second information device using the display screen in landscape orientation. Therefore, in the present invention, for example, for vertically long data, the display screen is displayed vertically. I Create image data. For landscape data, rotate the print image 90 degrees so that it can be displayed using the display screen in landscape orientation. Send To do. Thereby, in the second information device, for example, vertically long data such as a document is displayed in the vertically long direction of the display screen, and horizontally long data such as a table or a graph is displayed in the horizontally long direction of the display screen.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0029]
FIG. 1 shows data according to the present invention. Send 1 shows an embodiment of an information processing system for realizing a method, in which an application program is transferred from a personal computer as a first information device to a PDA as a second information device. I Image data Send 1 is a functional block diagram schematically showing a system configuration.
[0030]
The personal computer converts processing data into a format that can be understood by humans, or performs processing such as data update according to input information, an input device 2 such as a keyboard or a mouse that accepts user operations, images, To a display device 3 that shows information such as sound to the user, a storage device 4 that stores data temporarily converted to information such as data, images, and sound to be handled, and other devices such as personal computers and PDAs The connection device 5 is connected via a connection medium such as the Internet or a USB cable, and the printing device 6 prints out data stored in the storage device 4.
[0031]
The PDA includes a processing device 7 that performs a requested process in response to a user operation, an input device 8 that receives a user operation, a display device 9 that displays information such as images and sounds, and the like. The storage device 10 stores information received from a personal computer or PDA of the personal computer or stores internally converted data, and the connection device 11 that connects 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 the present embodiment, as a specific example, on a personal computer equipped with Windows (registered trademark of Microsoft Corporation: the same shall apply hereinafter), from a hypertext having information such as a figure, a text, and a link indicating a reference to another document, a PDA 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 using only 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 display page” is obtained from the input device 2 (step S1).
[0035]
For example, by operating using the input device 2, the 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 transferred to Windows and is normally printed by the printing device 6.
[0036]
This operation may be, for example, an operation of pressing a key on the keyboard, an operation of pressing a button indicating the start of transmission using a pointing device such as a mouse, or any other operation. May be.
[0037]
Upon receiving this operation, Windows passes the requested range of print image data to the PDA transmission print driver (step S3). The print driver for PDA transmission converts the received data into an image format (JPEG (Joint Photographic Experts Group), DIB (Device Independent Bitmap), etc.) for saving in the PDA (step S4), and sends this to the PDA. Believe (Step S5). Send File as a way to Send Use to print image data Send Or print image data on a network drive Send A method of (copying) can be considered.
[0038]
The network drive recognizes the storage devices of the first information device and the second information device as a pseudo storage device, and both storage devices recognize the other storage device as a counterpart storage device.
[0039]
The PDA performs processing according to processing determined in advance on the PDA, for example, storing the received print image data in the storage device 10 or displaying it on the display device 9 without saving.
[0040]
By executing such a series of processing, application data operated by the transmission source program is converted into basic data and transmitted to the PDA without performing any special processing on the transmission source program. Even in a PDA that does not support hypertext display, hypertext can be displayed as long as an image can be displayed.
[0041]
Next, a specific procedure for fetching print image data will be described with reference to a flowchart shown in FIG.
[0042]
First, a document to be imported as print image data is opened (step S11).
[0043]
Next, a pop-up menu shown in FIG. 5 is opened by clicking a task tray icon (not shown). In this pop-up menu, “Image capture (active window) (A)”, “Image capture (rectangular range designation) (R)”, “Print image capture (whole document) (D)” are used as image data capture methods. Since a menu such as “text capture (T)” is prepared, “capture print image (whole document) (D)” is selected here (step S12). As a selection method, it is possible to select from this pop-up menu, but it is also possible to select by pressing a “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). In this 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 the personal computer (in this embodiment, it is assumed as D drive), and this D drive is selected. However, the printer name may be set as a default value so that it can be used for 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 active window document is copied to the image file of the PDA (step S15).
[0046]
As a network drive Send Instead of (copying), for example as a JPEG file Send In order to do so, after the print image data is taken in at step S12, it is temporarily stored in the storage device 4 of the personal computer. Then, the connection state with the PDA is confirmed. 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 the 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, print direction (more precisely, the display direction) of data displayed on the PDA side. There are four types of resolutions: low (72 dpi) / medium (96 dpi) / high (150 dpi) / high (300 dpi), and the paper sizes are A3 / B4 / A4 / B5 / A5 / letter / Seven types of postcards are available. FIG. 8 shows the relationship between the paper size and the output resolution.
[0048]
FIG. 9 shows the correspondence (dot number comparison) between each size of VGA / SVGA / XGA / SXGA / UXGA, which is the image size of the display system, and each paper size. The user may set the paper size and resolution in accordance with such correspondence. For example, if it is desired to display A4 size print image data in the SVGA size on the PDA side, the paper size may be set to A4 and the resolution to 72 dpi on the property screen shown in FIG. As a result, the number of dots with a resolution of 72 dpi in A4 size becomes “horizontal: vertical = 855: 605”, which is almost the same as the number of dots of SVGA size “horizontal: vertical = 800: 600”, and the peripheral portion slightly protrudes. It is displayed in a size that almost fits on the display screen of the PDA.
[0049]
In the above processing, the acquired print image data is transmitted as it is to the PDA. However, depending on the display format of the display device on the PDA side, the appearance of the display may be different. Therefore, when creating print image data, perform color correction that matches the display format of the display device on the PDA side. Send You may make it do.
[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 so as to obtain a beautiful color when displayed on the PDA in consideration of the reflectance and the base color of the liquid crystal. . Further, when outputting to the projector via the PDA, the color correction of the print image data is performed in accordance with the color characteristics of the transmitted light of the liquid crystal used in the projector. Various specific methods for color correction have been proposed in the past, and those techniques can also be used in this embodiment, so detailed description thereof will be omitted here. As a result, the print image data can be displayed in an optimum color according to the display format of the display device 9 on the PDA side.
[0051]
As a method for selecting what color correction is performed on the print image data, for example, a color correction selection screen (not shown) is displayed on a personal computer screen, and “PDA (reflection liquid crystal)”, “ A name corresponding to a display format such as “projector (transmission type liquid crystal)” is displayed. Then, when the user selects a name from among them, color correction of the display format corresponding to the name may be performed. For example, when displaying print image data for presentation on a projector externally attached to the PDA, “projector” displayed on the color correction selection screen may be selected.
[0052]
If the amount of print image data is large, reduce the file size by performing color reduction or black-and-white conversion. Send May be.
[0053]
For example, when the display color of the display device 9 is 256 colors, the print image data to be created is also created with 256 colors instead of full color. Also, if the print image data is a regular document presentation, even if it is converted from color to black and white, there is almost no change in viewability. Create by converting to black and white. By reducing the file size in this way, the data Send However, the amount of data is easy to handle even in a PDA.
[0054]
When creating print image data, the screen size is easy to display on the PDA side. Send May be.
[0055]
When the second information device is a PDA, the size of the display screen is naturally limited. Then, print image data with a large capacity of one page is directly applied to the PDA whose screen size is limited in this way. Send Then, there is a problem that the entire page cannot be viewed unless the screen is scrolled many times. Therefore, by unifying to a screen size that is easy to display on a PDA (display standard, for example, VGA size), Send An easy-to-see screen can be displayed on the PDA without being affected by the image size of each page of the print image data. FIG. 10 shows this example. FIG. 6A shows an example of the print image data having a portrait size, and FIG. 9B shows an example of the print image data having a landscape size. PDA Send When doing so, as shown in FIGS. 3C and 3D, these print image data are unified to the same size (for example, VGA (640 × 480)). Send To do.
[0056]
Also, when creating print image data, create print image data according to the PDA image size, Send May be. That is, when creating print image data, the print image data is not created according to the normal paper size (A4, B4, A5, B5, postcard, etc.), but is matched to the image size of a display system such as a PDA or projector. Thus, 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. 4A shows an example in which the image size is specified by specifying the magnification, and FIG. 4B shows an example in which the image size is set by selecting a display system image size.
[0058]
In the magnification designation shown in FIG. 5A, setting is sometimes difficult because the user needs to remember the ratio between the paper size and the display image size. On the other hand, in the case of FIG. 5B, the type of image size is displayed in advance, and it is considered that the user can select a desired image size by selecting among them. In this case, it is possible to display VGA, SVGA, XGA as the image size, but these size displays are not generally known as paper sizes (A4, B4, B5, etc.). In the embodiment, the number of horizontal and vertical dots is used. Incidentally, “640 × 480” corresponds to the VGA size, and “800 × 600” corresponds to the SVGA size. The other items are items in which the user manually inputs 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]
The above is a configuration in which the user manually sets the image size of print image data to be transmitted to the PDA. However, it is also possible to automate the setting of such an image size.
[0061]
FIG. 12 shows a processing procedure for automatically setting the image size.
[0062]
The PDA and personal computer are connected by, for example, USB, and the PDA and personal computer are turned on (steps S21 and S31).
[0063]
When the PDA confirms that it is connected to the personal computer (when it is determined Yes in step S22), it transmits information on its display capability to the personal computer. The display capability information includes screen size, dot pitch, color depth, refresh rate, color characteristics, and the like.
[0064]
FIG. 13 shows a configuration example of a display capability information packet transmitted to the personal computer side. Following the header, data such as the PDA name, screen size, dot pitch, color depth, refresh rate, and color identification are recorded, and EOM is added at the end.
[0065]
The personal computer temporarily stores the display capability information transmitted from the PDA in the storage device 4 (step S32), and based on the stored display capability information, displays image characteristics such as the image size of the print image data to be created. Determine (step S33).
[0066]
In this way, by transmitting the display capability of the PDA to the personal computer in advance at the time of connection, an image size suitable for the screen size of the PDA can be obtained on the personal computer without the troublesome operation of the user setting the image size. Print image data can be automatically created. In the case of wireless communication, the display capability of the PDA is transmitted to the personal computer in advance when communication is possible.
[0067]
Also, depending on the user, vertical data such as A4 vertical and B4 vertical (such as documents) is displayed on the PDA using the screen vertically, and horizontal data such as A4 horizontal and B4 horizontal (tables, graphs, etc.) There is a demand for displaying a screen in a landscape orientation even with a PDA.
[0068]
Therefore, in the present embodiment, print image data is created so that the portrait data is displayed using the PDA screen in portrait orientation, and the landscape data is displayed using the PDA screen in landscape orientation. Data is created by rotating the print image 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 direction, and the data is also moved in the horizontal direction while moving from the upper left to the lower side on the VRAM of the storage device. Recording is performed sequentially (see FIG. 5B). When this data is transmitted to the PDA, the PDA displays the data shown in FIG. 5A on the 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, and sequentially scanned in the vertical direction while moving from the lower left to the right, and the data is also transferred from the lower left to the VRAM as the storage device. Recording is sequentially performed in the vertical direction while moving in the right direction (see FIG. 4D). When this data is transmitted to the PDA, the PDA displays the data shown in FIG. 4A on the vertically long screen (in a state where the display direction is rotated by 90 degrees). e)).
[0070]
Accordingly, as shown in FIG. 15, in the PDA, for example, portrait data such as a document is displayed in a portrait orientation on a portrait display screen (see FIG. 15A), and landscape data such as a table or graph is displayed in portrait orientation. It is displayed in the landscape direction on the screen (see FIG. 5B).
[0071]
By the way, when the vertically long data is displayed by using the PDA with the screen vertically and the horizontally long data is displayed by using the PDA with the screen horizontally long as described above, each time the user displays the data, The PDA itself must be rotated 90 degrees according to the display state (vertical display or horizontal display). In addition, when viewing the display with the screen horizontally long, as shown in FIG. 15B, the button arrangement is also in the horizontal direction, and there is a problem that the button operation is difficult.
[0072]
FIG. 16 shows an embodiment for eliminating the inconvenience of rotating the PDA itself by hand and the difficulty of operating buttons 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 plan view and a holding body 53 that holds the display unit main body 52, and the display unit main body 52 is rotatably held via a rotation mechanism unit (not shown). The structure is held by the body 53. In this case, various buttons are provided on the holding body 53 side. An operation button 54 for rotating the display unit 52 is also provided on the holding body 53. The user presses the operation button 54 to change from the state of the vertically long screen shown in FIG. 5A to the state of the horizontally long screen shown in FIG. 5B and the state of the horizontally long screen 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. As a result, the user does not need to rotate the PDA itself, and the button arrangement does not change with the rotation, so that the operability is improved.
[0074]
In the above-described embodiment, the display unit main body 52 is rotated by the user's button operation. However, when the print image data is created by rotating 90 degrees on the personal computer side, the rotation information is also included in the print image data. In addition, when the PDA receives this rotation information, the display unit main body 52 can be automatically rotated 90 degrees. Thus, by automatically rotating the display unit main body 52 in accordance with the display form of the created print image data, the user is always in the most viewable state without being conscious of the display form such as portrait or landscape. You can see the contents of the display screen.
[0075]
Incidentally, the print image data can be additionally embedded with information depending on the format. For example, in the case of JPEG, information can be embedded in an area called an application marker segment.
[0076]
Even if the data cannot be embedded, the same function can be realized by preparing other data and indicating that the data is additional information for the print image data. For example, when storing print image data as a file, another text file is prepared, and the name of the print image data file to be associated and the added information are written together, so that the same as the application marker segment of JPEG. A function can be realized.
[0077]
Then, by describing the conditions when the print image data is created in the additional information portion, the data can be manipulated more flexibly on the PDA.
[0078]
For example, if there is a means for displaying hypertext on the PDA, by embedding information (such as a URL) as shown in FIG. In addition to displaying the transmitted data, it is possible to actually access the data.
[0079]
An example of the result of performing a plurality of such additional information transmissions is shown in FIG.
[0080]
For example, in the example using the JPEG application marker segment, each row of the table shown in FIG. 18 corresponds to one JPEG file. In each JPEG file, the address (URL) of the web page referred to when each print image data is displayed as additional information in the application marker segment is written.
[0081]
In the information processing system described above, data is transferred between a personal computer that is the first information device and a PDA that is the second information device. Send This is realized by a program for causing the processing to function.
[0082]
