  The present invention relates to a still image generation server, a still image generation method, and a computer program that generate still image data based on moving image data received from a terminal.

  Conventionally, a communication network environment such as the Internet has been dramatically improved, and a broadband environment has become widespread. Broadband refers to a broadband connection capable of high-speed communication such as ADSL, CATV Internet, optical fiber, and FWA, and with the spread of such a network environment, moving image content distribution with a relatively large amount of data is performed.

For example, when distributing content for remote lectures, a viewer can add data such as a captured image at an arbitrary timing when viewing the content, and when viewing again, the system can view additional data in synchronization with the content Is disclosed.
JP 2006-262139 A

  According to Patent Document 1, content to be processed is prepared in advance in a server device. Then, the captured image is acquired at a timing when a user input is accepted when the moving image is reproduced. The acquired captured image is displayed during the subsequent reproduction of the moving image. For example, when the user presses the capture button, the image displayed at that time is captured for the first time. As described above, since the capture process is performed every time a user input is received, the load on the terminal that performs the capture process is heavy.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

[System overall configuration]
FIG. 1 is a diagram illustrating an overall configuration of a still image generation system 1 according to an example of the present embodiment.

  The still image generation system 1 in the present embodiment includes a still image generation server 10 (hereinafter referred to as server 10) and a terminal 20 connected to the communication network 30 via the server 10.

  The server 10 includes various servers such as a Web server 11, a moving image reception server 12, an encoding server 13, a DB (database) server 14, and a storage server 15. Moreover, the router 19 which is a relay device between the various servers described above and the communication network 30 may be included. In this embodiment, the hardware of the server 10 is configured using a plurality of servers for each function in order to distribute the load of each process. However, the single server 10 has a plurality of functions. In addition, a plurality of servers having one function may be configured, and the number of servers is not limited.

  In the present embodiment, the router 19 has a function of distributing a server to be received based on a protocol of data transmitted from the terminal 20. For example, if the communication is based on SMTP (Simple Mail Transfer Protocol) that is a mail protocol, the video reception server 12 may use FTP (File Transfer Protocol) or HTTP (Hyper Text Transfer Protocol) used for uploading from a Web page. For example, the router 19 distributes to the Web server 11.

  The terminal 20 includes a PC (personal computer) 21x having a camera 22x, a mobile phone 21y with a camera 22y, and a PC 21z to which a camera 22z is externally attached via a cable or the like. The terminal 20 transmits the moving image data captured by the camera 22 to the server 10 via the communication network 30. Further, the still image data is displayed by the user specifying the timing while reproducing the moving image. Therefore, the terminal 20 needs to be a terminal capable of attaching the camera 22 inside or outside. Moreover, since it displays a moving image and a still image, it is necessary to provide a display.

  In the present embodiment, the moving image is captured and transmitted to the server 10, and the moving image data is received from the server 10 and reproduced by the single terminal 20, but the moving image is captured and transmitted to the server 10. The terminal 20 and the terminal 20 that receives and reproduces moving image data from the server 10 may be different terminals. For example, the terminal 20 to be played back may not have the camera 22.

  The communication network 30 connects the server 10 and the terminal 20. Here, the communication network 30 is not only realized by a cable, but is realized partly by a radio via a base station, such as a mobile phone, or by a wireless LAN via an access point. Any communication network that meets the technical idea of the present invention may be used.

[System functional configuration]
FIG. 2 is a functional block diagram of the server 10 according to an example of the present embodiment.

  The server 10 mainly includes a control unit 110, a storage unit 120, and a transmission / reception unit 130. The control unit 110 of the server 10 includes a reception control unit 111, a file format determination unit 112, a still image generation unit 113, a still image transmission control unit 114, a moving image generation unit 116, and a moving image transmission control unit 117.

  The reception control unit 111 receives moving image data via the transmission / reception unit 130. Here, the moving image data is received by being attached to an e-mail addressed to the server 10 from the terminal 20 or being uploaded from a Web page displayed on the terminal 20. The moving image data is composed of a plurality of continuous image data.

  The file format determination unit 112 determines whether the file format of the moving image data is a format that can generate still image data. For example, it is determined whether the file format is a moving image such as MPEG (Moving Picture Experts Group) or AVI (Audio Video Interleaving).

  The still image generation unit 113 generates still image data corresponding to each image data of a plurality of image data constituting the moving image data. The still image data is data in an image file format such as JPEG (Joint Photographic Experts Group), for example. The still image transmission control unit 114 transmits the corresponding still image data to the terminal 20.

  The moving image generation means 116 generates moving image content from the moving image data. This moving image content refers to content that can be viewed from any terminal 20 without installing dedicated viewing software. For example, moving image content converted into Flash (registered trademark) can be viewed on the terminal 20 using a Web browser. The moving image transmission control unit 117 sequentially transmits the corresponding moving image content to the terminal 20.

The storage unit 120 stores moving image data received from the terminal 20, still image data generated by the still image generating unit 113, moving image content generated by the moving image generating unit 116, and text data. Also, a content management table 60 and a reproduction management table 90 described later are stored.
The transmission / reception unit 130 transmits / receives data between the terminal 20 and the control unit 110.

[Data conceptual diagram]
Next, the relationship between still image data and moving image content generated in the present invention and moving image data as input data will be described. FIG. 3 is a diagram illustrating a data concept according to an example of the present embodiment.

  First, the moving image data A is composed of a plurality of continuous image data a1 to a9. Still image data b1 to b6 are generated from the image data a1 to a9. Still image data b may have a one-to-one correspondence with image data a (b1 to b3 for a1 to a3, etc.), and still image data b may be 1 for image data a (N) ( b4 for a4 and a5, b6 for a7 to a9). In addition to the generation of the still image data b, the moving image content C is generated from the moving image data A.

[Data generation processing flow]
Next, a data generation process performed by the server 10 when uploading moving image data from a Web page displayed on the terminal 20 will be described. FIG. 4 is a data generation process flowchart of the server 10 according to an example of the present embodiment. FIG. 5 is a diagram illustrating an example of a screen displayed on the terminal 20 according to an example of the present embodiment. FIG. 6 is a diagram showing a content management table 60 according to an example of the present embodiment.

  In FIG. 4, first, in step S <b> 101, the control unit 110 of the server 10 transmits a Web page for uploading moving image data in response to a request from the terminal 20. Thereafter, the terminal 20 displays a screen as shown in FIG.

  Here, the upload page 50 displayed on the terminal 20 will be described with reference to FIG. The upload page 50 is a Web page for inputting moving image data to be uploaded and comments as necessary. When the moving image data is designated, the moving image data is directly designated in the moving image data designation column 51 for designating a location (directory) where the moving image data is present. The moving image data may be specified by pressing the reference button 52 to display the directory. In addition, a comment regarding the moving image to be uploaded is input to the comment input field 53. The input comment can be displayed on a screen for displaying still image data, for example. When uploading the designated moving image, moving image data is transmitted to the server 10 by pressing the enter button 54. When the upload is stopped, a predetermined page such as returning to an initial screen (not shown) is displayed by pressing the cancel button 55.

  Returning to FIG. 4, in step S <b> 102, the control unit 110 (reception control unit 111) receives the moving image data uploaded from the terminal 20. For example, when moving image data is uploaded by a web page, the web server 11 shown in FIG. 1 receives the moving image data. When a comment is input, the control unit 110 (reception control unit 111) receives the comment data together. Thereafter, in step S103, the control unit 110 stores the received moving image data in the storage unit 120.

  Next, in step S104, the control unit 110 determines whether or not comment data has been received. When the comment data is received (step S104: Y), the control unit 110 stores the comment data in the storage unit 120 in association with the moving image data (step S105). Thereafter, the control unit 110 moves the process to step S106. When comment data is not received (step S104: N), the control part 110 moves a process to step S106.

  In step S106, the control unit 110 (file format determination unit 112) determines whether or not the file format of the received moving image data is a predetermined one. The determination as to whether the file format is a predetermined one is performed, for example, by storing an allowable file format in the storage unit 120 and comparing the stored file format with the file format of the received moving image data. Also good. Alternatively, a program that generates still image data from moving image data may be executed to determine whether or not the program can be generated based on the result code of the program. If the file format of the moving image data is a predetermined one (step S106: Y), the control unit 110 moves the process to step S107. On the other hand, when the file format of the moving image data is not a predetermined one (step S106: N), this process is terminated without performing the subsequent processes.

  In step S107, the control unit 110 (still image generating unit 113) generates still image data from moving image data. Specifically, by selecting a plurality of image data constituting the moving image data and correcting the selected image data, still image data with higher image quality than the image data is generated. For example, the encoding server 13 shown in FIG. 1 generates still image data. Thereafter, in step S108, the control unit 110 stores the still image data in the storage unit 120 in association with the moving image data. For example, still image data and moving image data are stored in the storage server 15 shown in FIG.

  In step S109, the control unit 110 (moving image generating unit 116) generates moving image content from moving image data. Specifically, in order to provide moving image data as moving image content to a user via a Web page, for example, moving image content converted into Flash (registered trademark) is generated. Thereafter, in step S110, the control unit 110 stores the moving image content in the storage unit 120 in association with the moving image data.

  Here, the content management table 60 for managing various data stored in the storage unit 120 will be described with reference to FIG. This is one method shown for associating moving image data with still image data or the like. The content management table 60 is a table that is stored in the storage unit 120 and associates the moving image data received from the terminal 20 with various data. As shown in FIG. 6, the control unit 110 assigns a unique ID 61 to the received moving image data, and assigns an index that associates the moving image data, the still image data, the moving image content, and the text data as the accompanying data with each ID. Thus, the ID 61 is associated with the moving image data 62, the still image data 63, the moving image content 64, and the accompanying data 65. For example, the DB server 14 illustrated in FIG. 1 stores the content management table 60.

  In the example of FIG. 6, the record whose ID is “0001” is the case where the accompanying data is received together with the moving image data, and the still image data and the moving image content are generated because the moving image data has a convertible file format. In the moving image data 62, “A0001” added as an index of moving image data is stored, and in the still image data 63, “B0001” added as an index of still image data is stored. Also stores a character string assigned as an index. A record with ID “0002” indicates that the accompanying data has not been received, and a record with ID “0003” indicates that the file format of the received moving image data cannot be converted. By having such a content management table 60, association of each data is easily performed.

  Thereafter, the control unit 110 ends this process. Here, in FIG. 4, the moving image content is generated after generating the still image data from the moving image data. However, the moving image content may be generated in parallel with the generation of the still image data. Still image data may be generated after moving image content is generated.

  With this processing, the server 10 can automatically generate still image data and moving image content based on the moving image data received from the terminal 20. Then, the server 10 can generate still image data that is an image with higher image quality than the image data constituting the moving image data.

[Reproduction processing flow]
Next, the reproduction process performed by the server 10 will be described. FIG. 7 is a reproduction processing flowchart of the server 10 according to an example of the present embodiment. 8 and 10 are diagrams showing examples of screens displayed on the terminal 20 according to an example of the present embodiment. FIG. 9 is a diagram showing a playback management table 90 according to an example of the present embodiment.

  First, in step S <b> 121, the control unit 110 transmits a content selection page for reproducing moving image content stored in the storage unit 120 to the terminal 20.

  Here, FIG. 8A shows an example in which the terminal 20 displays a content selection page 80 for reproducing moving image content. On the content selection page 80, one scene of moving image data is displayed for each of the plurality of moving image data. One scene to be displayed may be, for example, the first image of the moving image content or an image after an arbitrary time has elapsed. Here, in the terminal 20, for example, an image of the ballet presentation shown in (F) can be selected with a mouse or the like.

  Returning to FIG. 7, in step S <b> 122, control unit 110 determines whether or not reproduction request data has been received from terminal 20. When the reproduction request data is received (step S122: Y), the control unit 110 (moving image transmission control unit 117) transmits a screen for reproducing moving image content, and sequentially transmits the corresponding moving image content to the terminal 20 ( Step S123). If the reproduction request data is not received (step S122: N), the process waits until the reproduction request data is received in step S122.

  Here, FIG. 8B shows an example in which the terminal 20 displays the reproduction page 180 for reproducing the moving image content. The playback page 180 includes a video content display unit 181 that displays the selected video content, a button unit 182 that plays back the video content, a shutter unit 183 that is selected by the user at the timing of acquiring still image data, and the acquired still image. And a page creation button 185 for creating a Web page using still image data. The button unit 182 can be arbitrarily operated by the user, and buttons such as a play button 182a and a stop button 182b are prepared.

  When acquiring still image data, a user using the terminal 20 selects still image request data from the terminal 20 by selecting the shutter unit 183 with a mouse or the like at the timing of acquisition while looking at the moving image content display unit 181. Is transmitted to the server 10.

  Next, in step S <b> 124, the control unit 110 determines whether still image request data has been received from the terminal 20. When the still image request data is received (step S124: Y), the control unit 110 selects, from the storage unit 120, still image data corresponding to data relating to the moving image reproduction time included in the still image request data (step S125). . At that time, the selected still image data is stored in the reproduction management table 90. On the other hand, when still image request data is not received (step S124: N), the control unit 110 moves to step S123 and waits for reception of still image request data while reproducing moving image content.

  Here, the reproduction management table 90 will be described with reference to FIG. The reproduction management table 90 is a work area stored in the storage unit 120, and is a table that temporarily stores still image data selected during reproduction of moving image content. Here, the number 91 is a number that identifies the user who is playing the video content on the terminal 20, for example, a number such as a user ID may be assigned in advance as a membership system, and may be used. It may be a number assigned by the control unit 110 in the order of communication. The data unit 92 stores still image data selected by the terminal 20. Here, a name such as a file name uniquely indicating a still image is stored, but still image data itself may be stored.

  Returning to FIG. 7, in step S <b> 126, control unit 110 (still image transmission control unit 114) transmits the still image data selected in step S <b> 125 to terminal 20.

  Here, FIG. 10A shows a reproduction page 180 when a plurality of still image data is acquired. Still image data of moving image content displayed at the timing when the shutter unit 183 is selected is displayed on the stock unit 184. When the same processing is performed a plurality of times, still image data is displayed in the order of processing from the left still image 184a to the still image 184e.

  Returning to FIG. 7, in step S127, the control unit 110 determines whether or not the reproduction of the moving image content has ended. The end of the reproduction of the moving image content means a case where transmission to the end of the moving image content is performed or a case where a stop button 182b (see FIG. 8B) of the button unit 182 is selected. When the reproduction of the moving image content is finished (step S127: Y), the control unit 110 moves the process to step S128. On the other hand, if the reproduction of the moving image content has not ended (step S127: N), the control unit 110 returns to step S123 and continues to reproduce the moving image content.

  In step S128, control unit 110 determines whether still image display request data has been received. The still image display request data is transmitted to the server 10 when the page creation button 185 in FIG. 10A is selected. When the still image display request data is received (step S128: Y), the control unit 110 generates a Web page displaying the still image and transmits it to the terminal 20 (step S129), and ends this process. On the other hand, when the still image display request data is not received (step S128: N), the control unit 110 continues in step S128 and waits to receive the still image display request data.

  The web page displaying a still image is, for example, a photo album as shown in FIG. If there is a comment in the moving image data, the comment may be displayed together.

  As described above, the moving image content is generated from the moving image data captured by the user using the camera 22, and the user can easily obtain desired still image data of the moving image content using the generated moving image content. it can. Further, since the still image data is high-quality image data, it can be used in various ways such as printing out as a photograph and sending it to a friend.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above. In addition, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. In addition, although embodiment mentioned above and the deformation | transformation form mentioned later can also be used in combination as appropriate, detailed description is abbreviate | omitted.

(Deformation)
As described above, various modifications and changes are possible without being limited to the embodiments described above, and these are also within the scope of the present invention.

  In this embodiment, the case where PC21x (or PC21z) was used as the terminal 20 was demonstrated. However, the present invention is not limited to this, and may be realized in the mobile phone 21y. The mobile phone 21y can capture and transmit moving image data, and can be realized in the same manner as in the case of the PC 21x (or PC 21z) by a playback page for the mobile phone. In that case, it is desirable that a button corresponding to the shutter unit is determined in advance so as to be easily implemented in the mobile phone 21y.
