Can be converted. In this embodiment, “content” is specifically image data or moving image data, and “application conditions set for each application” are the maximum size and maximum resolution of these images and moving images. is there.

  FIG. 2 is a hardware configuration diagram of the communication terminal 1. The communication terminal 1 physically includes a CPU (Central Processing Unit) 111, a RAM (Random Access Memory) 112 and a ROM (Read Only Memory) 113 that are main storage devices, and an operation unit 114 such as an input key that is an input device. , A terminal device having a display (display unit) 115, a wireless communication unit 116, and the like. Each function of the communication terminal 1 shown in FIG. 1 is obtained by reading predetermined computer software on hardware such as the CPU 111 and the RAM 112 shown in FIG. This is realized by operating the communication unit 116 and reading and writing data in the RAM 112 and the ROM 113.

  Next, each function of the communication terminal 1 shown in FIG. 1 will be described.

  The content list display unit 11 acquires content (images or moving images), creates a content list screen (for example, FIG. 7) in which these contents are arranged in a form (content object) that can be dragged such as thumbnails and icons, and displays the content list screen. 115. The content acquisition source is data stored in the main body of the communication terminal 1, data acquired from a server external to the communication terminal 1, or a camera (not shown) attached to the communication terminal 1 and still being the main body Includes unsaved data.

  FIG. 3 is a diagram illustrating information included in the content. As shown in FIG. 3, the content includes “extension”, “content main body” indicating the type of content, “DRM (Digital Rights Management)” indicating whether data can be copied, “thumbnail image”, “resolution”, “file” "Size" information is included. In the present embodiment, “resolution” and “file size” of the information are appropriately changed according to the application conditions of the application to which the content is applied.

  The drag process detection unit 12 detects that one arbitrary content is being dragged from the content thumbnails displayed on the content list screen. Here, the “drag operation” is an operation of moving any one content while pressing it with a finger when the display 115 of the communication terminal 1 is a touch panel, for example, and using a pointing device This is an operation in which the cursor is moved onto an arbitrary content via the operation unit 114, and the cursor is moved while pressing the enter key. When the drag process detection unit 12 detects a drag operation, the drag process detection unit 12 transmits the extension and DRM information of the content on which the drag operation is performed to the application extraction unit 15.

  As shown in FIG. 4, the content processing table 13 holds the “content type” corresponding to the extension of the content in association with the “application type” indicating the type of one or more applications to which this content can be applied. ing. The content is attached to the mail when the “application type” is “mail”, and is set as the background image of the standby screen when the “standby image”. Further, in the case of “save to server”, it is uploaded and saved to a specific external server, and in the case of “save to body”, it is saved in a memory area built in the body of the communication terminal 1. In the case of “mail with animation”, it is set as the background animation for HTML mail.

  The application processing table 14 holds information such as constraint information set for each application type. FIG. 5 is a diagram illustrating an example of the configuration of the application processing table 14. As shown in FIG. 5, the application processing table 14 includes an individual table for each content type. In the present embodiment, since image data and moving image data are targeted as contents, an image table 14a and a moving image table 14b are provided. The image table 14a and the moving image table 14b are both “application type”, “icon” indicating this application, “maximum resolution” and “maximum file size” set for each application type, “with DRM” (content Is displayed as a single record.

  As shown in FIG. 5, since the application processing table 14 includes separate tables 14a and 14b for images and moving images, the maximum resolution and the maximum depending on whether the content type is an image or a moving image even for the same application type. It is possible to change the application condition of the file size. For example, when the application type is “standby image”, the maximum file size is 5 MB in the image table 14a, but 10 MB in the moving image table 14b. When the application type is “store on server”, the maximum resolution is XVGA in the image table 14a, but QVGA in the moving image table 14b.

  The application extraction unit 15 extracts an application corresponding to the dragged content. Specifically, the application extraction unit 15 acquires the content type and application type associated with the extension from the content processing table 13 based on the extension information of the content received from the drag processing detection unit 12. Further, based on the content type acquired from the content processing table 13, a table to be used (the image table 14 a or the moving image table 14 b) is selected from the application processing table 14, and the application type acquired from the content processing table 13 is selected. Based on the selected table, an icon corresponding to the application type is acquired. When the application extraction unit 15 acquires an icon from the application processing table 14 and the DRM information of the content received from the drag processing detection unit 12 is “Yes”, the application processing table 14 sets “DRM Yes”. Only applications whose column is set to “Yes” (that is, usable even if data replication is not possible) are extracted.

  The application icon display unit 16 creates an icon list screen on which the application icons (application objects) extracted by the application extraction unit 15 are arranged, and displays the icon list screen on the content list screen (for example, FIG. 9).

The drop processing detection unit 17 detects that the dragged content detected by the drag processing detection unit 12 has been dropped to any one of the icons displayed on the application icon display unit 16. Here, the “drop operation” refers to, for example, when the display 115 of the communication terminal 1 is a touch panel, the user moves the finger over any one application icon while pressing any one content with the finger and then moves the finger. In the case of using a pointing device, the cursor is placed on any one content, and the cursor is moved onto any one application icon while pressing the enter key of the operation unit 114. This is an operation of releasing the enter key after letting it go.
Upon detecting the drop operation, the drop processing detection unit 17 transmits to the content conversion processing unit 18 the content type of the content on which the drag operation has been performed and the application type of the application on which the dragged content has been dropped. To do.

  The content conversion processing unit 18 converts the content so as to satisfy an application condition set according to the type of application detected by the drop processing detection unit 17. Specifically, the content conversion processing unit 18 selects a table (image table 14a or moving image table 14b) to be used in the application processing table 14 based on the content type received from the drop processing detection unit 17, and performs drop processing. Based on the application type acquired from the detection unit 17, information on the maximum resolution and the maximum file size corresponding to the application type is acquired from the selected table. When the resolution and file size of the dropped content are larger than the maximum resolution and maximum file size acquired from the application processing table 14, the content resolution and file size are set to be equal to or less than the maximum resolution and maximum file size. Perform content conversion processing. The content conversion processing unit 18 transmits the content subjected to the conversion process to the application starting unit 19.

  The application activation unit 19 activates the application and changes to the operation screen in a state where the content converted by the content conversion processing unit 18 is selected. For example, when the application type is “mail”, the mail creation screen starts with the content attached, and when the application type is “standby screen”, the standby screen is displayed with the content set as the background of the standby screen. In the case of “save to server”, after uploading the content to the server, the URL of the uploaded site is displayed in the browser, and in the case of “save to body”, the content is stored in the body memory and then stored. A data list screen showing the contents of the selected data area is displayed.

  Next, the processing executed in the communication terminal 1 of the present embodiment will be described using the flowchart shown in FIG. 6, and the content conversion method according to the present embodiment will be described. FIG. 6 is a flowchart showing processing executed in the communication terminal 1 of the present embodiment.

  First, content (image or video) is acquired by the content list display unit 11, and a content list screen in which these contents are arranged in a form that allows drag operations such as thumbnails and icons is created and displayed on the display 115 (S101). : Object display step). For example, as shown in FIG. 7, the content list screen 21 displays a list of icons or thumbnails 22 of image data and moving image data acquired by the content list display unit 11.

  Next, as shown in FIG. 8, the drag processing detection unit 12 detects that one arbitrary content 22a is dragged from the content thumbnails 22 displayed on the content list screen 21 (see FIG. 8). S102: Drag operation detection step).

  Further, the application extraction unit 15 extracts an application that can process the dragged content (S103). Specifically, the application extraction unit 15 acquires the content type and application type associated with the extension from the content processing table 13 based on the extension information of the content received from the drag processing detection unit 12. Further, based on the content type acquired from the content processing table 13, a table to be used (the image table 14 a or the moving image table 14 b) is selected from the application processing table 14, and the application type acquired from the content processing table 13 is selected. Based on the selected table, an icon corresponding to the application type is acquired. When the application extraction unit 15 acquires an icon from the application processing table 14 and the DRM information of the content received from the drag processing detection unit 12 is “Yes”, the application processing table 14 sets “DRM Yes”. Only applications whose column is set to “Yes” (that is, usable even if data replication is not possible) are extracted.

  Next, the application icon display unit 16 creates an icon list screen in which the application icons extracted in step S103 are arranged. For example, the created icon list screen 23 is displayed on the content list screen 21 as shown in FIG. It is displayed above (S104: application display step).

  Further, the content 22a detected by the drop processing detection unit 17 as being dragged in step S102, for example, as shown in FIG. 10, is an arbitrary icon 23a on the icon list screen 23 displayed in step S104. It is detected that a drop operation has been performed (S105: drop operation detection step).

  Next, the content conversion processing unit 18 converts the content so as to satisfy the application condition set according to the type of application detected in step S105 (S106: content conversion processing step). Specifically, the content conversion processing unit 18 selects a table (image table 14a or moving image table 14b) to be used in the application processing table 14 based on the content type received from the drop processing detection unit 17, and performs drop processing. Based on the application type acquired from the detection unit 17, information on the maximum resolution and the maximum file size corresponding to the application type is acquired from the selected table. When the resolution and file size of the dropped content are larger than the maximum resolution and maximum file size acquired from the application processing table 14, the content resolution and file size are set to be equal to or less than the maximum resolution and maximum file size. Perform content conversion processing.

  Then, the application is started by the application activation unit 19 while the content converted in step S106 is selected, and the operation screen is displayed (S107).

  As described above, according to the communication terminal 1 and the content conversion method according to the present embodiment, an application indicating an application to which the content 22a can be applied according to the drag operation of the content icon 22a displayed on the display 115. A list of icons 23 is displayed on the display means. Then, the content icon 22a on which the drag operation is performed is dropped on one of the application icons 23a displayed in a list so that the application condition of the application 23a on which the drop operation is performed is matched. Conversion processing of the dragged content 22a is performed. With such a configuration, it is possible to convert content without using a special operation procedure using only intuitive and simple operations such as a drag operation and a drop operation that do not require learning.

  Further, since the application extraction unit 15 selects an application to which the content can be applied with reference to the content processing table 13 based on the content associated with the content thumbnail 22a on which the drag operation is performed, it is intuitive and simple. By simply performing a drag operation by operation, it becomes easy to identify an application to which the selected content can be applied, and the convenience of content conversion processing is improved.

  Further, since the content conversion processing means acquires application conformance conditions with reference to the application processing table 14 based on the application associated with the application icon 23a on which the drop operation has been performed, it is individually set for each application. Even if the user does not recognize the application condition of the content in advance, the content conversion process can be performed according to the automatically acquired matching condition, and the convenience of the content conversion process is improved.

  In addition, the application activation unit 19 activates the application associated with the application icon 23a on which the drop operation has been performed in a state where the content converted by the content conversion processing unit 18 is applied. The operation of selecting and the operation of starting the application again are not required, and the operability of the communication terminal is improved for the user.

  The communication terminal 1 and the content conversion method according to the present invention have been described with reference to the preferred embodiments. However, the present invention is not limited to the above embodiments. For example, in the above embodiment, image data and moving image data are illustrated as specific examples of content, but other data that can be converted, such as music data, can be applied.
