Description

  The present invention relates to simplification of the process of creating and displaying video content related to a content distribution service for mobile terminals, particularly mobile phones, and relates to an image processing method on the Internet.

  Since mobile terminals are smaller in size than the screen size of a personal computer, new models have been announced one after another since the launch of mobile terminals capable of browsing the Internet in 1999. As technology and battery performance for mobile devices improve and new functions are added, manufacturers are introducing mobile devices with larger screen sizes and higher resolutions to the market.

  However, since there is no industry standard for the ratio of screen size or screen specification, there are actually over 200 mobile terminal screen sizes ranging from 96 × 72 pixels to 240 × 320 pixels or 320 × 240 pixels. Existing.

  In addition to the screen size problem, there is no uniformity in the image format that can be displayed. That is, there are terminals that can display photo-realistic image images and other terminals that can display only GIF images, while other terminals can display JPEG images, GIF images, and PNG images.

  Furthermore, there is a problem of the capacity of the image file. Due to the limitations of the hardware that can be used for networks and mobile terminals, each mobile terminal manufacturer sets an upper limit on the capacity of images that can be downloaded. Since a high-accuracy image requires more capacity, the upper limit of the image capacity also affects the accuracy of the downloaded image.

  Taking the standby screen, which is the most popular video content on mobile devices, as an example, a company that wants to distribute a standby screen to a mobile device (a) has a screen size that depends on the type of mobile device it receives. It is necessary to create video content in an image format that matches the image format that can be displayed as beautifully as possible within the range of the file capacity of the portable terminal that matches is there.

  Conventionally, there have been the following two methods for creating video content optimal for a mobile terminal.

(1) Manual video conversion This method (a) investigates the screen size, displayable image format, capacity, etc. of the mobile terminal respectively, (b) creates the original high-precision video to be converted, (c) In accordance with the specifications of each mobile device that has been investigated, create a video converted one by one using image conversion software, and (d) a web page that contains the converted video content. This is done in the process of creating each mobile terminal.

(2) Video conversion using video server This method uses software that automatically converts the high-precision original video created in (1) (b) above according to the specifications of the mobile terminal (a). The conversion is performed using a built-in video server, and a web page including an instruction to go to the video server for the converted video content is created for each portable terminal.

  References in the technical field related to the present invention include the following.

JP 2002-175243 A

  However, in the method (1), there is a limit to the creation of video content corresponding to all mobile terminals. As a result, the size that covers the screen size of several mobile terminals (for example, 128 × 128 video content is 128 × 128, 144 × 144, 120 × 120, etc.) can be viewed), but it has not been possible to cope with the accuracy appropriate for the image format and capacity.

  The method (2) requires a process for instructing the specifications of the portable terminal to be converted to the video server, and has the same problem as the method (1) except that the conversion work is automated. there were. Since the conversion specifications instructed to the video server are different for each mobile terminal, it is necessary to create a web page for each mobile terminal for performing such instructions, and the type of video content (standby screen, icon, portrait) If an image or the like is specified, the conversion specifications differ depending on the type of video content, so the instruction to the video server is further complicated.

  The present invention has been made in view of such problems, and the video content created regardless of the specifications of the mobile terminal can be viewed in an optimum format for each mobile terminal, and is not affected by the mobile terminal. It is an object to create a single web page, and a system that can be compared is not known.

  In order to solve the above-mentioned problems, the present invention provides a module that functions with parameters written by a content or application creator.

  There are three types of modules: (a) video content type (standby image, thumbnail (small screen for preview), etc.), (b) original image file name, and (c) presence / absence of photo / realistic image. According to the parameters, it works in cooperation with the user agent sent from the mobile terminal that accessed the web page.

  The module can generate an optimal video conversion instruction for the accessed mobile terminal while referring to the information of the mobile terminal presented by the user agent using the three types of parameters.

  The video conversion instruction of the mobile terminal specification generated by the module is transmitted to the video server via the web page or directly from the module, and the video server follows the instruction and the original image is the optimum specification for the mobile terminal. And the video content is displayed on a web page to be displayed, or is transmitted to a Java (registered trademark) application and displayed.

  According to the present invention, a content or Java (registered trademark) application creator can freely create content without being restricted by the type and function of the mobile terminal.

  Also, the video server administrator can always view the optimal video content on all mobile terminals simply by updating the database corresponding to the mobile terminal.

  Embodiments of the present invention will be described with reference to the accompanying drawings.

  First, FIG. 1 will be described.

[1] Setup content or video content conversion parameters written by a Java (registered trademark) application creator are transmitted to the module and stored inside the module to determine the generation process of the video content conversion instruction.

[2] The user agent analysis module includes carrier information (Docomo (registered trademark), au (registered trademark), Vodafone (registered trademark), etc.) included in user agent information transmitted from the accessed portable terminal and a portable terminal model. Get information.

[3] Model support adjustment The module has a built-in list of support statuses for photo-realistic images for each model of mobile terminal, and the mobile terminal inquires the list of mobile terminal information taken by the module. Judge whether or not it corresponds to a realistic image. Even if the parameters written by the content or Java application creator require support for photo-realistic images, the accessed mobile device does not support photo-realistic images. The module switches the photo-realistic image to non-compliant.

  Note that the conversion instruction selected for the presence / absence of support for the photo-realistic image is inquired again when the video conversion instruction is generated in FIGS.

[4] Generation of Conversion Instruction [1] and [2] in FIG. 2 show the case where the video content type is not wallpaper, and [1] and [2] in FIG.

  The module selects a conversion instruction generation process according to the type of video content indicated by the parameter. If the video content type is not wallpaper (Fig. 2), the module selects the conversion instructions in the GIF-based or PNG-based image format according to the mobile device carrier type obtained from the user agent, and the parameter information and this A video conversion instruction is generated together with the video conversion instruction that has been determined and selected. When the video content type is wallpaper (FIG. 3), the module selects the conversion instruction according to the mobile terminal carrier type and mobile terminal model information obtained from the user agent, and determines and sorts the parameter information and so far. A video conversion instruction is generated together with the video conversion instruction.

[5] In the case of FIG. 4 [2] web page, the conversion instruction transmission / conversion module returns the generated conversion instruction to the web page, and the web page transmits this to the video server. 3] In the case of a Java (registered trademark) application, the generated conversion instruction is sent from the module directly to the video server after giving an instruction for the application to correctly receive the converted video content.

  The video server acquires the original image according to the received conversion instruction (original image, image format, mobile terminal model, video content type), and stores the internal mobile terminal database (optimum size, Inquires about the corresponding capacity and the corresponding image format), obtains specific conversion information, and converts it to the optimal video content.

  The video server includes a mobile terminal database. If this database is updated, any mobile terminal can be supported semipermanently.

[6] Display The video server sends the converted video content to the web server, and the web server sends the text data together with the text data to the browser of the mobile terminal or sends it to the Java (registered trademark) application. Is displayed.
