  The Web page including the image data is formed so as to be able to accept an operation instruction in the vertical (vertical) direction or the horizontal (left / right) direction based on the image data included in the content file. Specifically, if the original content file contains image data captured from the upper, lower, left, or right imaging positions of the image data included in the displayed Web page, The inside web page can accept operation instructions in the direction (up / down / left / right) in which image data from different imaging positions exists.

  When the mobile phone 4 receives an operation instruction in any direction from the user via the browser software, the mobile phone 4 transmits a request for acquiring a Web page including image data corresponding to the direction instructed to the content server 2. Thus, the Web page including the image data is acquired, and the Web page acquired by the display update of the browser software is displayed.

  Thereafter, the mobile phone 4 repeats operation instruction reception via the browser software, Web page acquisition, and display update.

  FIG. 5B is a flowchart showing a processing flow of the mobile phone 4 having an application execution function. The mobile phone 4 having an application execution function acquires and displays content using browser software and a content acquisition / display application.

  First, the mobile phone 4 receives a connection request from the user to the content server 2 via the browser software and connects to the content server 2 to be stored in a content information table (not shown) of the content server 2. Content list information (list) including all content IDs is acquired, and any content ID is selectably displayed (list).

  When the mobile phone 4 accepts a selection input of any content ID from the user via the browser software, the mobile phone 4 transmits to the content server 2 a distribution request including the model information of the mobile phone 4 and the selected content ID. To do.

  The mobile phone 4 acquires the address of the Web page for acquiring the content acquisition / display application in which the content ID included in the distribution request and the address of the Web page for acquiring the content file are set. The content acquisition / display application is further acquired and executed by connecting to.

  If the content acquisition / display application is already stored, only the content acquisition / display application is used to acquire content list information (list), display (list), accept selection input of content ID, Transmission of the distribution request including the model information of the mobile phone 4 and the selected content ID may be performed. In this case, the Web server address for acquiring the converted content may be acquired from the content server 2 instead of the Web page address for acquiring the content acquisition / display application. .

  In this content acquisition / display application, the content ID included in the distribution request and the address of the Web page for acquiring the content file are set, a detailed model information collection function, and a Web page A function to connect to the address and a display function of the content file, etc., and when executed, collects detailed model information and sends an acquisition request including the collected detailed device information and content ID. The content file is transmitted to the conversion server 1 by connecting to the address of the Web page for acquiring the content file, and the content file converted based on the detailed device information is received from the conversion server 1.

  The mobile phone 4 that has received the converted content file displays the image data stored at the head of the image data included in the content file.

  Further, as described above, one or more pieces of image data are stored in the content file. When a plurality of image data are stored, the viewpoint is continuously displayed in the vertical (vertical) direction or the horizontal (left / right) direction. The image data captured while being moved is stored, and by continuously displaying these continuously captured image data in the vertical (vertical) direction and horizontal (left / right) direction, the user can display a three-dimensional image. It can be recognized.

  The content acquisition / display application of the mobile phone 4 accepts an operation instruction in the vertical (vertical) direction or horizontal (left / right) direction from the user, and continuously updates and displays image data corresponding to the direction in which the operation is instructed. By doing so, the 3D image is reproduced and displayed.

  Thereafter, the content acquisition / display application of the mobile phone 4 repeats operation instruction reception and display update.

  FIG. 6 is a flowchart showing the detailed processing contents of the conversion processing in the conversion server 1.

  The conversion server 1 determines the model of the mobile phone 4 based on the model information of the mobile phone 4 included in the distribution request transmitted from the mobile phone 4. Specifically, at least the model name of the mobile phone 4 is specified based on user agent information included in HTTP (Hyper Text Transfer Protocol) request data. Further, the screen size (vertical), screen size (horizontal), and corresponding image registered in the model information table (see FIG. 2A) of the storage unit 102 of the conversion server 1 in association with the specified model name. A format, an application environment type (whether or not an application has an execution function, an executable application type), and the like are specified.

  Based on the identified application environment type, the conversion server 1 determines whether or not the mobile phone 4 has an application execution function.

  Furthermore, based on the identified application environment type, the conversion server 1 determines the type of application that can be executed by the mobile phone 4.

  If it is determined that the application execution function is not provided, the conversion server 1 identifies the content file acquired from the content server 2 and extracts all the image data constituting the three-dimensional image included in the content file. The image format of these image data is converted into a corresponding image format.

  The conversion server 1 that has converted the image format of the image data converts these image data into Web pages one by one. In other words, Web pages including one image data are generated by the number of image data, and these Web pages are generated based on the connection in the vertical (vertical) direction and horizontal (horizontal) direction of the image data in the content file. A link is made so that the display is updated by an operation instruction in the vertical (vertical) direction or horizontal (left / right) direction, and the generated Web page is stored in the storage unit 102.

  The conversion server 1 that has converted to a Web page distributes the address of the Web page including the image data stored at the top in the content file, and ends the conversion process.

  If it is determined that the application execution function is provided, the conversion server 1 determines whether detailed model information of the mobile phone 4 has been received. If the detailed model information has not been received, the model name is specified based on the model information included in the distribution request transmitted by the mobile phone 4, and the model information table (FIG. 2A) is associated with the model name.

  In the conversion of the content file, first, the processing capability of the CPU is determined, and if it is determined that the processing capability is insufficient (eg, the processing speed is slow), the format of the image data included in the content file is changed. Conversion to a compatible image format of the mobile phone 4 is performed. Thereby, the processing time and processing load for the content acquisition / display application executed on the mobile phone 4 to convert the image data included in the content file into the corresponding image format of the mobile phone 4 can be reduced.

  The conversion server 1 that has performed conversion according to the processing capability of the CPU determines whether the mobile phone 4 can receive all the data included in the content file based on the free memory capacity available for the content acquisition / display application. To do.

  If it is determined that not all data can be received, the conversion server 1 first determines whether data other than the image data included in the content file, that is, link data is included.

  That is, the process for determining whether or not link data is included in the conversion process performed by the conversion server 1 of this embodiment forms the accompanying data presence / absence determination means in the present invention.

  If there is link data, the link data is deleted.

  Further, it is determined whether or not the memory capacity is sufficient to receive all the data included in the content file from which the link data has been deleted. If it is determined that the link data cannot be received, a part of the image data is deleted.

  In the process of deleting a part of the image data, the image data is deleted so as to reduce a sense of discomfort as much as possible when continuously displayed. For example, when the image data for one round in the horizontal direction is composed of twelve pieces, the content file can be deleted by deleting (thinning out) half of the image data, such as 2, 4, 6, 8, 10, 12. The data size is almost halved.

  When the image data is deleted, the distribution type of the image data is updated to 2, and the data is thinned out from the original content file (content file stored in the storage unit 202 of the content server 2). The content acquisition / display application can be specified to the effect. Also, the data size and the like of the header part are updated.

  Then, the conversion server 1 transmits the content file converted according to the processing capacity of the CPU and the free space of the memory available for the content acquisition / display application to the mobile phone 4.

  That is, the content file before conversion processing stored in the storage unit 202 of the content server 2 of the present embodiment corresponds to the master three-dimensional image data of the present invention, and the storage unit 202 of the content server 2 of the present embodiment The master data storage means of the present invention is formed.
