[Browsing data display processing executed by computer 10 and user terminal 20]
Based on FIG. 3, the browsing data display process executed by the computer 10 and the user terminal 20 will be described. This figure is a diagram showing a flowchart of viewing data display processing executed by the computer 10 and the user terminal 20. This viewing data display process is the details of the above-described transmission process for transmitting the viewing data (step S1), receiving process for receiving the viewing data (step S2), and display process for displaying the viewing data (step S3).

The viewing data request module requests transmission of viewing data larger than the display range of the user terminal 20 (step S10).
The fact that the viewing data is larger than the display range of the user terminal 20 means that when the user terminal 20 displays the viewing data on its own display unit, only a part of the viewing data can be displayed. For example, in the viewing data, if a plurality of image data exist as content, only one of the plurality of image data can be displayed.
The input reception module receives input of a URL of a predetermined web page, etc. For example, the input reception module may accept input based on an existing method of inputting a URL of a web page (for example, inputting a character string of a URL, accessing a set link).
The viewing data requesting module requests the computer 10 to transmit viewing data constituting a predetermined Web page based on the received URL input.

Browsing data will be explained based on FIG. 4. This figure is a diagram schematically showing an example of viewing data.
In the figure, viewing data 30 and a display range 34 of the user terminal 20 are shown. The viewing data 30 includes three types of image data, ie, first image data 31, second image data 32, and third image data 33, as contents. Note that the viewing data 30 includes other content (for example, text) in addition to these image data, but to simplify the explanation, the description of the content other than the image data is omitted. .
The display range 34 is a displayable range when the user terminal 20 displays the viewing data 30, and is a range surrounded by a broken line. When the user terminal 20 receives the viewing data 30, it displays only the viewing data 30 existing within the display range 34. When the viewing data 30 is larger than the display range of the user terminal 20, as shown in the figure, the user terminal 20 is unable to display all of the viewing data 30 at once, but displays only part of it.

Returning to FIG. 3, the continuation of the browsing data display process will be explained.
The viewing data transmission module transmits viewing data larger than the display range of the user terminal 20 (step S11).
The viewing data transmission module specifies viewing data desired by the user based on a request from the user terminal 20, and transmits viewing data larger than the specified display range of the user terminal 20 to the user terminal 20.

The viewing data receiving module receives viewing data larger than the display range of the user terminal 20 (step S12).
The viewing data receiving module receives viewing data that is larger than the display range of the user terminal 20 and transmitted from the computer 10 .

The display module displays the viewing data (step S13).
The display module displays the received viewing data on its own display unit (see FIG. 5). The display module displays a portion of the received viewing data.

Based on FIG. 5, the viewing data displayed by the display module will be explained. This figure is a diagram schematically showing an example of a display screen when the display module displays viewing data.
The figure shows a display screen 40 when the display module displays the viewing data 30. The display screen 40 shows a viewing range 35 surrounded by a broken line as a range corresponding to the display range 34 described above. In the viewing range 35, only the first image data 31 described above exists, and the second image data 32 and third image data 33 described above do not exist. Details of how to handle the second image data 32 and third image data 33 that do not exist in the viewing range 35 will be described later.
The user views the viewing data 30 that exists within this viewing range 35 out of the viewing data 30 . That is, the user is currently viewing the first image data 31 on the display screen 40.

The above is the viewing data display process.
The computer 10 and the user terminal 20 execute the process described later using the viewing data transmitted and received through this viewing data display process.

[Browsing data priority transmission/reception processing executed by computer 10 and user terminal 20]
Based on FIG. 6, the browsing data priority transmission/reception process executed by the computer 10 and the user terminal 20 will be described. This figure is a flowchart of viewing data priority transmission/reception processing executed by the computer 10 and the user terminal 20. This viewing data priority transmission/reception process includes the selection reception process (step S4) in which the user selects the viewing range desired by the user, and the selection transmission process (step S5) in which the data for which the selection of the viewing range desired by the user is received is transmitted. , a selection reception process (step S6) of receiving data for which the selection of the viewing range desired by the user has been accepted, a transmission process (step S7) of preferentially transmitting the viewing data corresponding to the viewing range for which the selection has been accepted; These are details of the receiving process (step S8) for preferentially receiving the viewing data corresponding to the accepted viewing range and the display process (step S9) for preferentially displaying the received viewing data.
This viewing data priority transmission/reception process is a process that uses the viewing data transmitted and received by the viewing data display process described above.

The selection reception module receives from the user of the user terminal 20 the selection of the viewing range desired by the user from among the viewing data (step S20).
The selection reception module receives input from the user to change the viewing range (for example, scrolling the screen), and receives selection of the viewing range desired by the user (see FIG. 7).

Based on FIG. 7, a state in which the selection acceptance module accepts selection of a viewing range will be described. This figure is a diagram schematically showing an example when the selection reception module receives a selection of a viewing range.
In the same figure, for the viewing data 30, selections from the viewing range 35 currently being viewed by the user to the viewing range 36 desired by the user are accepted. The viewing ranges 35 and 36 are each surrounded by broken lines. An example of a method for accepting selections is scrolling the screen. In the figure, the direction and amount of scrolling of the screen is indicated by an arrow 37.
The selection reception module accepts an input corresponding to this arrow 37 in order to change the display content from the viewing range 35 to the viewing range 36, and accepts the selection of the viewing range 36.
As a result, the selection reception module accepts the input corresponding to the arrow 37 for the viewing data 30 existing in the user's viewing range, and selects to change the content to be viewed from the first image data 31 to the third image data 33. will be accepted.

Returning to FIG. 6, the continuation of the viewing data priority transmission/reception process will be explained.
The selection transmission module transmits the data for which the viewing range has been selected (step S21).
The selection transmission module transmits to the computer 10 data necessary for specifying viewing data in the viewing range for which the selection has been accepted. This data is, for example, the scroll amount of the screen and the content included in the viewing range after selection.

The selection receiving module receives the data for which the viewing range has been selected (step S22).
The selection reception module receives the data transmitted by the user terminal 20 and necessary for specifying the viewing data in the viewing range 36 .

The viewing range determination module determines whether or not the viewing data being transmitted has been received outside the viewing range according to the user's selection (step S23).
The viewing range determination module is necessary to identify the viewing data that is being sent (the viewing data that was being sent at the time the user terminal 20 accepted the selection of the viewing range) and the viewing data of the viewing range selected by the user. Based on the data, it is determined whether the viewing data being sent is outside the viewing range selected by the user.
If the viewing range determination module determines that the transmitted viewing data has not received data that is outside the viewing range (step S23 NO), that is, the viewing data being transmitted is within the viewing range selected by the user. If it is determined that the viewing data is within the range, the computer 10 continues to send the viewing data that is being sent, and ends the viewing data priority transmission/reception process.
In this case, in terms of the viewing data 30 described above, only the first image data 31 exists in the viewing range 36 selected by the user. In other words, this is a case where neither the second image data 32 nor the third image data 33 exists in the viewing range 36 selected by the user.

On the other hand, if the viewing range determination module determines that the transmitted viewing data has received data that is outside the viewing range (step S23 YES), that is, the viewing data being transmitted is within the viewing range selected by the user. If it is determined that the viewing data is outside the range, the viewing data transmission module interrupts the transmission of the viewing data that is being sent (step S24).
In this case, in terms of the viewing data 30 described above, this is a case where the second image data 32 or the third image data 33 exists in the viewing range 36 selected by the user. In other words, this is a case where the first image data 31 does not exist in the viewing range 36 selected by the user.
The viewing data transmission module interrupts the transmission of the viewing data that is being sent at the time of receiving the data that accepts the selection of the viewing range.
The viewing data transmission module interrupts the transmission of the first image data 31 in FIG. 7 described above. Note that, if the transmission of the first image data 31 has been completed, the viewing data transmission module does not need to interrupt the transmission of the first image data 31.

With the interruption of the transmission of viewing data by the computer 10, the viewing data receiving module suspends the reception of the viewing data being received (step S25).
The viewing data receiving module interrupts the reception of the viewing data that is being received at the time when the viewing range selection is accepted.
The viewing data receiving module interrupts the reception of the first image data 31 in FIG. 7 described above. Note that if the viewing data receiving module has completed receiving the first image data 31, there is no need to interrupt receiving the first image data 31.

The process of step S23 described above may be executed by the user terminal 20.
In this case, the user terminal 20 may determine whether the received viewing data is outside the viewing range based on the viewing range for which the selection has been accepted. If the user terminal 20 determines that it is not out of the viewing range, it continues to receive the viewing data that it is receiving, and ends the viewing data priority transmission/reception process. On the other hand, if the user terminal 20 determines that it is out of the viewing range, it suspends the reception of the viewing data that it is receiving. As the reception of the viewing data is interrupted, the user terminal 20 requests the computer 10 to suspend the transmission of the viewing data that it is receiving. Based on this request, the computer 10 interrupts the transmission of viewing data that is being transmitted.

The browsing data transmission module preferentially transmits the browsing data corresponding to the selected browsing range (step S26).
The viewing data transmission module preferentially transmits viewing data corresponding to the selected viewing range to the user terminal 20.
In FIG. 7 mentioned above, the viewing data transmission module preferentially transmits the third image data 33 existing in the viewing range 36. The viewing data transmission module interrupts the transmission of the first image data 31 and does not transmit the second image data 32, thereby preferentially transmitting the third image data 33. . The viewing data transmission module may transmit the interrupted first image data 31 and the untransmitted second image data 32 at least after the transmission of the third image data 33 is completed.

The browsing data receiving module preferentially receives the browsing data corresponding to the selected browsing range (step S27).
The viewing data receiving module preferentially receives viewing data corresponding to the viewing range for which the selection transmitted by the computer 10 has been accepted.
In FIG. 7 described above, the viewing data receiving module preferentially receives the third image data 33 existing in the viewing range 36. The viewing data receiving module interrupts reception of the first image data 31 and does not receive the second image data 32, thereby preferentially receiving the third image data 33. . The viewing data receiving module may receive the interrupted first image data 31 and the unreceived second image data 32 at least after the reception of the third image data 33 is completed.

The display module displays the viewing data (step S28).
The display module displays the received viewing data preferentially on its own display unit.
In FIG. 7 described above, the display module displays only the received third image data 33 on its own display section (see FIG. 8).

Based on FIG. 8, the viewing data displayed by the display module will be explained. This figure is a diagram schematically showing an example of a display screen when the display module displays viewing data.
The figure shows a display screen 50 when the display module displays the viewing data 30. The display screen 50 shows a viewing range 36, which is a range surrounded by broken lines. In this viewing range 36, only the third image data 33 exists, and the first image data 31 and the second image data 32 do not exist.
The user views the viewing data 30 that exists in this viewing range 36 out of the viewing data 30 . That is, the user is currently viewing the third image data 33 on the display screen 50.

The above is the viewing data priority transmission/reception process.

[Browsing data pre-reading process executed by computer 10 and user terminal 20]
Based on FIG. 9, the browsing data prefetching process executed by the computer 10 and the user terminal 20 will be described. This figure is a diagram showing a flowchart of browsing data prefetching processing executed by the computer 10 and the user terminal 20.
This viewing data pre-reading process is a process that uses the viewing data transmitted and received by the viewing data display process described above. Further, the present viewing data pre-reading process is a process that is performed after displaying the viewing data in the viewing range in the viewing data priority transmission/reception process described above.

The completion determination module determines whether reception of viewing data within the viewing range has been completed (step S30).
The completion determination module determines whether all contents of the viewing data existing in the currently displayed viewing range have been received.
The completion determination module determines whether reception of the third image data 33 as the viewing data 30 existing in the viewing range 36 in FIG. 8 described above has been completed.
When the completion determination module determines that reception of the viewing data within the viewing range is not completed (step S30 NO), that is, when determining that reception of the third image data 33 is not completed, this viewing data Wait until reception is complete.

On the other hand, when the completion determination module determines that the reception of the viewing data within the viewing range has been completed (step S30 YES), that is, when determining that the reception of the third image data 33 has been completed, the specific module The specific module calculates the distance between the center of the current viewing range and the centroid of each content of the out-of-viewing data, and based on the calculated distance, Specify the order in which each piece of viewing data is received. The specific module calculates this distance based on Equation 1 below. The specific module specifies the order in which each content of the viewing data outside the viewing range is to be received in order of the shortest calculated distance.

In Equation 1 above, wx is the x-coordinate of the center of the viewing range, and wy is the y-coordinate of the center of the viewing range. Further, ix is the x coordinate of the center of gravity of the content of the viewing data, and iy is the y coordinate of the center of gravity of the content of the viewing data. Each coordinate is based on a rectangular coordinate system with a predetermined point in the viewing data as the origin.

An example in which the specific module specifies the order will be described based on FIG. 10. This figure is a diagram schematically showing an example of specifying the order in which the specific module receives viewing data outside the viewing range. In addition, in the figure, the first image data 31 and the second image data 32 will be described on the assumption that the reception thereof has not been completed.
The identification module identifies the coordinates (wx, wy) of the center 60 of the viewing range 36. The specific module also specifies each of the coordinates (ix1, iy1) of the center of gravity 61 of the first image data 31 and the coordinates (ix2, iy2) of the center of gravity 62 of the second image data 32 that are outside the viewing range 36.
The specific module calculates the distance (first distance) between the center 60 of the viewing range 36 and the center of gravity 61 of the first image data 31. The specific module also calculates the distance (second distance) between the center 60 of the viewing range 36 and the center of gravity 62 of the second image data 32.
The specifying module compares the calculated first distance and the second distance, and specifies the order in descending order of the numerical values. In FIG. 10, the specific module calculates each distance in the order of the second distance and the first distance, so the second image data 32 is the first and the first image data 31 is the second. Identify things and their order.
Note that the specific module may perform processing such as assigning the specified order to the viewing data, thereby setting the order to the viewing data.

Returning to FIG. 9, the continuation of the browsing data prefetching process will be explained.
The viewing data request module requests transmission of viewing data based on the specified order (step S32).
The viewing data requesting module requests the computer 10 to transmit each content of the viewing data based on the specified order.
The viewing data request module requests the computer 10 to transmit the second image data 32 having the first specified order.

The viewing data transmission module transmits the viewing data based on the order first (step S33).
The browsing data transmission module first transmits sequential browsing data to the user terminal 20 based on a request from the user terminal 20 .
The viewing data transmission module first transmits this second image data 32 to the user terminal 20 based on a request from the user terminal 20.

The processing in steps S30 to S33 described above may be performed by the computer 10, omitting the processing in step S32.
This case will be explained.
In FIG. 8 described above, the computer 10 determines whether transmission of the third image data 33 as the viewing data 30 existing in the viewing range 36 has been completed (processing corresponding to step S30). If the computer 10 determines that the transmission of the viewing data within the viewing range has not been completed, that is, if it determines that the transmission of the third image data 33 has not been completed, the computer 10 waits until the transmission of this viewing data is completed. stand by.
On the other hand, when the computer 10 determines that the transmission of the viewing data within the viewing range has been completed, that is, when determining that the transmission of the third image data 33 has been completed, the computer 10 transmits the viewing data outside the viewing range. The order of transmission is specified (processing corresponding to step S31). The computer 10 executes a process similar to the process of step S31 described above, and specifies this order. At this time, the computer 10 may obtain the viewing range of the user terminal 20 in advance.
The computer 10 first transmits the viewing data based on the order (processing corresponding to step S33). The computer 10 transmits the second image data 32 having the first specified order to the user terminal 20.

The viewing data receiving module prefetch viewing data based on the order (step S34).
The viewing data receiving module receives viewing data based on the order in which the computer 10 transmitted it, and pre-reads this viewing data.
The viewing data receiving module receives the second image data 32 and prefetches the second image data 32.

The computer 10 and the user terminal 20 execute the processes of steps S32 to S34 described above in the specified order, and repeat them until pre-reading of the viewing data outside the viewing range is completed. That is, when the pre-reading of the second image data 32 is completed, the computer 10 and the user terminal 20 next execute the processes of steps S32 to S34 described above for the first image data 31 which is second in order, The first image data 31 is read in advance.
The computer 10 and the user terminal 20 perform similar processing when there is viewing data for subsequent orders.
Note that the user terminal 20 may resume reception of the browsing data to be prefetched and receive the corresponding browsing data for which reception was previously interrupted, or may continue to receive the browsing data that had been received up to the point of interruption. The data may be discarded and new corresponding viewing data may be received again.

The above is the browsing data prefetching process.
When the process of step S20 described above is performed after the main viewing data prefetching process is executed, if the viewing range for which selection has been accepted is the viewing data prefetched by the process of step S34 described above, step It is sufficient to omit the processing in S26 and S27 and display the prefetched viewing data.

In each of the above-mentioned processes, the case where the viewing data is image data has been described, but it goes without saying that the present invention is also applicable to the case where the viewing data is data other than image data. Further, although the present invention has been described using only a single piece of image data existing in the viewing range as an example, it goes without saying that the present invention is not limited to a single piece of image data.
In the viewing data transmission/reception process, if the viewing data being viewed falls outside the viewing range as a result of accepting the selection of the viewing range, the viewing data display system 1 interrupts the transmission/reception of the viewing data that is outside the viewing range, Any method is sufficient as long as it preferentially transmits and receives viewing data that corresponds to the viewing range for which the selection has been accepted.
In addition, in the browsing data prefetching process, the browsing data display system 1 specifies the order in which the browsing data outside the browsing range is to be sent and received after transmitting and receiving the browsing data within the browsing range, and based on the specified order, the browsing data Any device that can send and receive data and read browsing data in advance is fine.

Although each of the above-mentioned processes is described as a separate process, the computer 10 and the user terminal 20 may be configured to execute a part or all of the above-mentioned processes in combination. Further, the computer 10 and the user terminal 20 can be configured to execute each process at a timing other than the timing described above.
