In the present embodiment, the processing means of the mobile terminal 10 receives the position information and the event information by displaying a pointer movable by an operation button as an input means on a display as a display means. Subsequently, the processing unit of the mobile terminal 10 transmits the position information and the event information in the image displayed based on the received image file to the information transfer server 20 (S60).

  The processes from the next steps S65 to S80 are implemented by an information transfer program process executed by the processing means of the information transfer server 20.

  The processing means of the information transfer server 20 receives position information and event information in an image displayed based on the image file from the mobile terminal 10. Subsequently, the processing means of the information transfer server 20 reads X ′ = c * X, Y ′ = c * Y as predetermined functions with reference to the position information conversion file (S65). Then, the processing means of the information transfer server 20 displays based on the received image file based on c = 1/100 as the enlargement / reduction ratio read in step S55 and the predetermined function read in step S65. The position information on the screen of the web browser associated with the position information in the image to be acquired is acquired (S70). In this embodiment, the processing means of the information providing server uses coordinates (X ′, Y ′) as position information in the image displayed based on the image file based on the enlargement / reduction ratio and the predetermined function. Coordinates (X, Y) = (100 * X ′, 100 * Y ′) as position information on the screen of the associated web browser can be acquired.

  Subsequently, the processing means of the information transfer server 20 issues an event corresponding to the event information received from the portable terminal 10 at coordinates (X, Y) corresponding to the position information on the acquired web browser screen (S75). ).

  The processing in the next step S80 is implemented by a web browser program process executed by the processing means of the information transfer server 20.

  The processing means of the information transfer server 20 performs a predetermined process when detecting the event (S80). For example, when there is a link to another web page at coordinates (X, Y) as position information on the screen of the web browser, and the event information received from the mobile terminal 10 is a click, the information transfer server 20 The processing means transmits a web page acquisition request corresponding to the link to the external web server 30 based on the web page display control information (HTML). The subsequent processing is the same as that after step S25.

  As described above, the information transfer server 20 converts the web browser screen into an image file, transmits the image file to the terminal device, and executes the function of the web browser based on the position information and event information in the image received from the mobile terminal 10. Thereby, even if it is the portable terminal 10 with low performance compared with PC, while displaying the information of the desired web page, the process based on the display control information of the said web page can be performed.

  Since whether or not an image file can be displayed hardly depends on the model of the mobile terminal 10, the mobile terminal 10 uses a language (for example, HTML, Compact HTML, etc.) that describes display control information of a desired web page. Regardless, the information on the web page can be displayed.
