Description

  The present invention relates to a mobile terminal display system for displaying a Flash (registered trademark) format file on a screen of a mobile terminal.

  As one of the functions of a mobile phone, there is a function of displaying a user's current position on a map on the screen of the mobile phone by using position information acquired by GPS (Global Positioning System) (for example, Patent Documents). 1). In order to use such a function, it is necessary to install in advance a dedicated application for displaying a map using a BREW (registered trademark) or JAVA (registered trademark) application.

  However, at present, complete cooperation between a dedicated application for displaying a map and an Internet browser for a mobile terminal is not possible. The dedicated application for map display and the Internet browser for mobile terminals are separate programs and are launched as different applications. Therefore, the mobile phone's Internet browser is displayed on the mobile phone screen while using the dedicated map display application. It cannot be displayed. On the other hand, a dedicated application for displaying a map cannot be used while an Internet browser for a mobile terminal is being displayed.

  It is desirable to be able to scroll the map after displaying the map with an Internet browser for mobile terminals. However, due to various limitations of existing Internet browsers for mobile terminals, It is difficult to realize. With existing Internet browsers for mobile devices, if you want to display the map on the screen and then scroll it up, down, left, or right, you must receive the scrolled map again and display the received map. .

Accordingly, it is conceivable to use FlashLite (registered trademark) as a method for scrolling and displaying a map in an Internet browser for a portable terminal.
Recent Internet browsers for mobile terminals can use FlashLite to display dynamic images. FlashLite can write programming scripts such as ActionScript (registered trademark) to represent dynamic images. By using it, you can easily scroll the map.

  However, since FlashLite has a restriction that the maximum capacity that can be displayed on a mobile phone screen is 100 KB or less, the entire map cannot be displayed on the mobile phone screen with one Flash file.

Therefore, as shown in FIG. 5, the entire map is divided into a plurality of parts, and the maps are converted into flash files (Flash files A to F) having a capacity that can be displayed on the screen of the mobile phone, respectively. It can be sent to an internet browser. In this way, by dividing the entire map into a plurality of parts and converting each map into a Flash file, the map displayed on the screen of the mobile phone by one Flash file can be scrolled up, down, left and right. As shown in FIGS. 5 and 6, during scrolling, a screen area 61 indicating an area displayed on the screen of the mobile phone in the map 60 that can be displayed by one Flash file is a boundary line of the map 60 (for example, In the case of moving to the next map 60 (the map 60 that can be displayed by the Flash file B) beyond the end of the map 60 that can be displayed by the Flash file A), the Flash file corresponding to the adjacent map 60 is the Internet of the mobile phone. Sent to the browser. Thereby, the user can see the entire map while scrolling the map on the screen of the mobile phone.

FIG. 7 is a diagram showing an existing portable terminal display system using FlashLite.
A mobile terminal display system 70 shown in FIG. 7 includes an Internet browser 71 for mobile terminals provided in a mobile terminal (mobile phone), a WEB server 72, an I / O (Input Output) access unit 73, an HDD (Hard Disk). (Drive) 74.

  When the WEB server 72 receives the URL transmitted from the Internet browser 71 and indicating the recording location of the next Flash file, the WEB server 72 reads the Flash file corresponding to the URL from the HDD 74 via the I / O access unit 73, and The read Flash file is transmitted to the Internet browser 71 using a TCP / IP (Transmission Control Protocol / Internet Protocol) protocol.

According to the mobile terminal display system 70 configured as described above, the Flash file corresponding to the map next to the scroll destination can be transmitted from the WEB server 72 to the Internet browser 71.

  However, since the mobile terminal display system 70 uses FlashLite, a new Flash file is read from the HDD 74 by a URL (Uniform Resource Locator), and the Flash file is transmitted to the Internet browser 71 as described above. It has only a configuration. Therefore, as shown in FIG. 8, after the Flash file corresponding to the map 60 adjacent to the scroll destination is sent to the mobile phone, the screen area 61 comes to the center of the map 60 which is the initial position, and the scroll display is smooth. There is a problem that can not be.

  Then, an object of this invention is to provide the portable terminal display system which can scroll-display the map displayed on the screen of a portable terminal smoothly.

In order to solve the above problems, the present invention adopts the following configuration.
That is, the mobile terminal display system 1 of the present invention makes a request for acquiring a mobile terminal on which a flash file is displayed, recording means for recording a plurality of flash files, and a flash file transmitted from the mobile terminal. When received, the flash file corresponding to the request is read from the recording means, and a parameter indicating the position of the area displayed on the screen of the mobile terminal in the image displayable by the plurality of Flash files is extracted from the request. A WEB server that replaces the parameter of the Flash file read from the recording unit with the parameter extracted from the request, and transmits the Flash file with the replaced parameter to the portable terminal.

  According to the mobile terminal display system configured in this way, during scrolling, before and after the area displayed on the screen of the mobile terminal exceeds the boundary line of the map displayed by one Flash file, the mobile terminal Since the area displayed on the screen can be at the same position, the map can be smoothly scrolled between these different Flash files.

  In addition, when the WEB server of the present invention receives a request to earn a flash file transmitted from a portable terminal, the WEB server reads a flash file corresponding to the request from the recording unit and also records a plurality of files recorded in the recording unit. A parameter indicating the position of an area displayed on the screen of the mobile terminal in an image that can be displayed by a Flash file is extracted from the request, and the parameter of the Flash file read from the recording unit is rewritten with the parameter extracted from the request. The flash file with the parameters rewritten is transmitted to the portable terminal.

  In addition, the WEB server retrieves the parameter from the request by CGI, and rewrites the parameter indicated in the numerical area of the ActionScript variable in the Flash file read from the recording unit to the parameter retrieved from the request. You may comprise.

  The image that can be displayed by the plurality of Flash files may be a map, a photograph, or a picture.

  ADVANTAGE OF THE INVENTION According to this invention, the map displayed on the screen of a portable terminal can be scrolled smoothly.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a portable terminal display system according to an embodiment of the present invention.
A mobile terminal display system 1 shown in FIG. 1 includes an Internet browser 2 for a mobile terminal provided in the mobile terminal, a WEB server 3, a CGI (Common Gateway Interface) 4, and an HDD 5. The mobile terminal is, for example, a mobile phone that can display a Flash file. Here, the mobile phone capable of displaying the Flash file refers to a mobile phone in which Macromedia Flash Lite 1.0 (registered trademark) or Macromedia Flash Lite 1.1 (registered trademark) is mounted. The HDD 5 can be replaced with other recording means such as a ROM (Read Only Memory) and a RAM (Random Access Memory).

  When the WEB server 3 receives a URL as a request indicating that a Flash file transmitted from the Internet browser 2 is desired to be acquired, the WEB server 3 activates and receives the CGI 4 as a parameter processing program for the Flash file recorded in the HDD 5. The URL is transferred to the CGI 4 and the flash file received from the CGI 4 is transmitted to the Internet browser 2 using the TCP / IP protocol.

FIG. 2 is a flowchart for explaining the operation of the CGI 4.
First, the CGI 4 reads a template flash file from the HDD 5 based on the URL received from the WEB server 3. (S1) The flash file read at this time is recorded in a memory provided in the WEB server 3. The CGI 4 acquires the URL received from the WEB server 3 through an environment variable called QUERY_STRING. The C language source at the time of actual programming is char * query = getenv (“QUERY_STRING”);

Next, the CGI 4 sequentially searches each block in the Flash file read in S1. (S2)
Here, FIG. 3 is a diagram showing a block structure in the Flash file.

The Flash file 30 shown in FIG. 3 has blocks of a file head 31, graphic data 32, image data 33, and ActionScript 34.
In FIG. 2, the CGI 4 determines whether or not the block searched in S <b> 2 is ActionScript. (S3)
When it is determined that it is not ActionScript (No in S3), CGI4 returns to S2 and searches for the next block.

On the other hand, when it is determined that it is ActionScript (S3 is Yes), CGI4 sequentially searches for a plurality of variables in the ActionScript. (S4)
Next, the CGI 4 uses the parameter retrieved in S4 as a parameter included in the URL received from the WEB server 3 (a value indicating the position of the screen area 61 in the entire map that can be displayed by the Flash files A to F shown in FIG. 5). It is determined whether or not it matches a variable having a numerical area indicated by. (S5) For example, when the parameter is “a = 1, b = 2, c = 3”, the parameter is “http://test.co.jp/test.swf?a=1&b=2&c= 3 ”, it is included in the URL transmitted from the Internet browser 2 to the WEB server 3.

If it is determined that the variables do not match (No in S5), the CGI 4 returns to S4 and searches for the next variable.
On the other hand, when it is determined that the variables match (S5 is Yes), the CGI 4 rewrites the parameter indicated in the numerical area of the variable to the parameter included in the URL received from the WEB server 3 (overwriting). (S6)
Then, the CGI 4 transmits the Flash file having the ActionScript with the parameters overwritten in S6 from the WEB server 3 to the Internet browser 2. (S7)
As described above, in the mobile terminal display system 1 according to the present embodiment, in the CGI 4, the parameter indicated in the numerical area of the ActionScript variable in the new Flash file read from the HDD 5 by the URL transmitted from the Internet browser 2 is set to the URL. As shown in FIG. 4, the position of the screen area 61 can be made the same before and after the screen area 61 crosses the boundary line of the map 60, as shown in FIG. You can scroll the map smoothly between files.

In addition, the said portable terminal display system 1 is not limited to the said embodiment, It can deform | transform and implement at any time in the range which does not deviate from the summary of this invention.
For example, an icon of a button that can be linked to a WEB page indicating regional information corresponding to the predetermined position is created at a predetermined position of the map created with the Flash file, and a linked WEB page is created with the Flash file. When jumping back to the linked WEB page and returning to the map again, as described above, the parameter can be overwritten by the CGI 4 so that a smooth link operation can be performed.

  By configuring in this way, when a button in a predetermined map among the divided maps is pressed by the user's operation and jumps to the link destination, when returning to the map again, the same map as before the link Can return to position.

  Moreover, in the said embodiment, although the image displayed on the screen of a mobile telephone by a Flash file is a map, it is not specifically limited, such as a photograph and a picture.

It is a figure which shows the portable terminal display system of embodiment of this invention. It is a flowchart for demonstrating the operation | movement of CGI. It is a figure which shows the block structure of a Flash file. It is a figure which shows the scroll operation | movement in the portable terminal display system of this embodiment. It is a figure which shows each Flash file at the time of dividing | segmenting the whole map into plurality. It is a figure which shows the scroll operation | movement within one Flash file. It is a figure which shows the existing portable terminal display system. It is a figure which shows the scroll operation | movement in the existing portable terminal display system.
