  The URL information transmitting unit 62 performs processing for transmitting the URL information extracted by the URL information extracting unit 60 to the system mobile communication terminal 10 that is the transmission source of the image data for access.

  The image domain registration means 64 performs processing for converting registration desired image data desired to be registered in the database 54 into a common format format and registering it as reference image data in the database 54 in association with the URL information.

  Further, the image domain server 26 is provided with a feature amount extraction unit 68, a similarity ratio calculation unit 70, and a determination unit 72. The feature amount extraction unit 68 calculates the feature amounts of the access image data and the reference image data. The feature amount of the image data for access is extracted when the image data for access is stored in the storage unit 66 by the access image data receiving unit 56, and is extracted from the image data for access converted into the common format format. The extracted feature amount is stored in the storage unit 66 in association with the image data for access.

  The feature amount of the reference image data is extracted when the reference image data is stored in the database 54 by the image domain registration unit 64, and the feature amount extracted from the reference image data converted into the common format is the reference image. The data 54 is stored in the database 54 in association with the data.

  In the present embodiment, the feature amount of the reference image data and the feature amount of the image data for access are obtained by convolution of the Laplacian filter, Hough transform, etc. for structural features such as edges, lines, and contours indicated by the image. ing. However, what is used for feature amount extraction is not limited to the structural features described above, and for example, color or texture may be used.

  The similarity ratio calculating means 70 calculates the similarity ratio using feature amounts of two image data such as reference image data and access image data, or reference image data and desired registration image data. The similarity rate is a value indicating the degree of similarity between two images, and the higher the value, the more similar the images are.

  The determination unit 72 compares the similarity rate calculated by the similarity rate calculation unit 70 with a preset criterion value, and satisfies the criterion when the similarity rate is higher than the criterion value. The two image data used to calculate the similarity ratio are regarded as the same, and when the similarity ratio is equal to or less than the determination reference value, it is determined that the determination criterion is not satisfied, and the similarity ratio is determined as Two image data used for calculation are regarded as non-identical.

  Hereinafter, regarding the functions and operations of the video distribution server of the present invention, when a new user newly registers in the video distribution system, when registering an image for access, when uploading a video, the website is accessed by the image for access This will be described with reference to the flowcharts for the case where the image data is downloaded and the case where the moving image data is downloaded.

  FIG. 8 is a flowchart for a new registration in the moving image distribution system. It is assumed that an ID number and a password for a new user to access the moving image distribution system are determined in advance when applying for new registration.

  An ID number and a password (PW) are transmitted from the system mobile communication terminal 10 (S1). The web server 20 receives the ID number and password by the access information receiving means 28 (S2), and determines whether they are authenticated (S3). If it is not authenticated, the fact is transmitted to the system mobile communication terminal 10. If it has been authenticated, the model discriminating means 30 discriminates the carrier and model of the accessing system mobile communication terminal 10 (S4).

  Next, the content data creation server 24 creates content data by the content data creation means 50 (S5). The content data is created for every carrier and every model and is stored by the content data storage means 52 (S6).

  Next, the web server 20 uses the content data search means 32 to search for content data that can be browsed by the carrier and model determined by the model determination means 30 (S7). The search place is the content data storage means 52 in the content data creation server 24, but may be a database in which content data is separately stored. Then, content data suitable for the carrier, that is, viewable content data is read by the content data reading means 34 (S8), a website is created by the website creation means 40 (S9), and the website data transmission means 41 is used for the system. It transmits to the portable communication terminal 10 and makes browsing possible with the portable communication terminal 10 for systems (S10).

  Next, the system mobile communication terminal 10 selects a category-specific background and simultaneously transmits an image, a message, and the like to be pasted on the background (S11). Specifically, various backgrounds (for example, for a Christmas party, for a birthday party, for a wedding party, etc.) can be selected on a website, and a new user selects a desired background. . Then, the message to be displayed is written in the message field, and an image to be pasted on the background is attached and transmitted to the web server 20.

  The web server 20 searches the data by the content data search means 32 in advance and completes the website in addition to the content data read by the content data reading means 34. Then, the URL information of the website is created by the QR code creating means 42 and transmitted to the mobile communication terminal 10 for the system of the new user by the QR code sending means 43 (S12). Here, it is determined whether or not to create an image domain (S13). If not created, initial registration ends here. The new user can obtain URL information from the transmitted QR code and access the website. By attaching this QR code to an e-mail or the like and sending it to a friend or the like, it is possible to promote your own website.

  Next, a case where an image domain is created will be described. FIG. 9 is a flowchart when an image domain is created following FIG. The application program of the system mobile communication terminal 10 is started (V1), registration desired image data is created in advance, and stored in the storage means in the system mobile communication terminal 10 (V2). The system mobile communication terminal 10 displays a screen for image domain registration after the web server 20 creates and transmits a QR code. The file name of the registration desired image data desired to be registered is displayed. An entry field is provided, and when the system mobile communication terminal 10 is operated, a file name is entered in the entry field, and when the registration button is clicked, the system mobile communication terminal 10 sends it to the image domain server 26. Registration desired image data is transmitted (V3).

  When the image domain server 26 receives the registration desired image data from the system mobile communication terminal 10 by the access image data receiving means 56 (V4), it is regarded as the same as the other reference image data already stored in the database 54. (V5), and when it is determined that there is other reference image data regarded as identical (V6), registration to the database 54 as reference image data is rejected. In this case, returning to the point A in the flowchart, another desired registration image data is created. When it is determined that they are regarded as non-identical, that is, when it is determined that there is no other reference image data regarded as identical, storage in the database 54 is permitted as reference image data (V7).

  Specifically, when receiving the registration request image data from the system mobile communication terminal 10, the image domain registration means 64 converts the registration request image data into a common format. Then, the feature amount of the registration desired image data having the common format is extracted by the feature amount extraction unit 68, and the similarity rate with the feature amount of other reference image data stored in the database 54 is the similarity rate calculation unit 70. Is calculated by

  Here, when a plurality of reference image data is stored in the database 54, similarity ratios for all the reference image data are calculated. Then, it is determined by the determining means 72 for each similarity ratio whether or not it is equal to or less than the determination reference value, and when it is determined that all are equal to or less than the determination reference value, Assuming that the reference image data does not exist in the database 54, the reference image data is stored in the database 54 as reference image data.

  In addition, when reference image data whose similarity is higher than the criterion value already exists in the database 54, registration in the database 54 is rejected on the assumption that there is other reference image data that is regarded as the same. Thereby, double registration in which a plurality of URL information is registered in association with reference image data regarded as the same is prevented.

  Next, FIG. 10 is a flowchart for uploading moving image data from the system mobile communication terminal 10 to a website. Since the user has already been registered, the e-mail address for uploading the video is informed. After creating the moving image data, the user attaches the moving image data to the moving image upload e-mail address and transmits it (Q1).

  The moving image data desired to be uploaded is received by the moving image receiving means 44 in the moving image conversion server 22 (Q2) and encoded by the moving image conversion means 46 (Q3). Encoding is performed for each carrier and each model, and the encoded moving image data is stored for each carrier and each model by the moving image data storage means 48 (Q4).

  Next, the web server 20 can discriminate the carrier and model of the system mobile communication terminal 10 to which the video data has been uploaded by the model discrimination means 30, and can browse the system mobile communication terminal 10 by the video data search means 36. Search for video data (Q5). Although the search is in the moving image data storage means 48 in the moving image conversion server 22, the moving image data may be stored in advance in a database or the like, and this database may be searched.

  The moving image data searched by the moving image data search means 36 is read by the moving image data reading means 38 (Q6), and its thumbnail data is created (Q7). Next, the website creation means 40 creates a website from the thumbnail data and the content data read in advance by the content data reading means at the time of initial registration (Q8). That is, it is possible to confirm that the upload has been completed by displaying a thumbnail of the video data uploaded from the system mobile communication terminal 10 on the website. If there is additional video data to be uploaded (Q9), it is sufficient to return to point B in the flowchart and repeat the same operation.

  FIG. 11 is a flowchart for receiving URL information from a registered access image and accessing a website. First, when an application program is started by the user operating the system mobile communication terminal 10 (R1), the system mobile communication terminal 10 enters a shooting mode in which shooting by a camera is possible. When shooting is performed by the user operating the camera, the application program creates image data of the shot image (R2), stores the image data in the storage unit of the system mobile communication terminal 10, and accesses the image. Data is transmitted to the image domain server 26 via the Internet 16 (R3).

  When the access image data receiving unit 56 receives the access image data from the system portable communication terminal 10 (R4), the image domain server 26 converts the image data into the common format and stores it in the storage unit 66. At this time, the feature amount extraction unit 68 extracts the feature amount from the access image data converted into the common format, and stores the feature amount together with the access image data in the storage unit 66.

  Then, the reference image data search means 58 searches the database 54 (R5), and among the plurality of reference image data stored in advance in the database 54, reference image data regarded as the same as the access image data is found. It is determined whether or not it exists. Here, the similarity ratio is calculated by the similarity ratio calculation means 70 using the feature quantity of the image data for access stored in the storage means 66 and the feature quantity of the reference image data stored in the database 54. The

  When a plurality of reference image data is stored in the database 54, the similarity ratios for all the reference image data are calculated. Then, the determination means 72 determines each similarity rate. The reference image data search means 58, when there is reference image data determined by the determination means 72 to have a similarity higher than the determination reference value, the reference image data is regarded as the same as the access image data. Select as image data. Further, as a result of the determination by the determination means 72, when there are a plurality of reference image data having a higher similarity than the determination reference value, one reference image data having the highest similarity is regarded as the same as the image data for access. Selected as reference image data.

  When the reference image data that is considered to be the same as the access image data is selected by the reference image data search means 58, the URL information stored in the database 54 in association with the reference image data is the URL information extraction means 60. (R6). Then, the URL information extracted by the URL information extracting means 60 is transmitted by the URL information transmitting means 62 to the system mobile communication terminal 10 that is the image data transmission source for access (R7).

  When the determination unit 72 determines that all the similarity ratios are equal to or less than the determination reference value, the reference image data search unit 58 determines that there is no reference image data that is regarded as the same as the access image data. The URL absence information indicating the determination result is transmitted by the URL information transmitting means 62 to the system mobile communication terminal 10 that is the transmission source of the image data for access.

  When receiving the URL information from the image domain server 26 (R8), the application program of the system portable communication terminal 10 stores the URL information in the storage means (R9) and accesses the address of the web server 20 having the URL information (R10). ), Processing for receiving the content data from the web server 20 is performed. When URL absence information is received from the image domain server 26, the information is displayed on the main display screen.

  Therefore, the image data for access, which is considered to be the same as the reference image data registered by the system user, is created by the user shooting with the camera of the system mobile communication terminal 10 and transmitted to the image domain server 26. The URL information can be received from the image domain server 26 to the system mobile communication terminal 10, and the image data can be used instead of the code in which the URL information is written.

  FIG. 12 is a flowchart for browsing a moving image of a website from the general mobile communication terminal 13. First, a website is accessed from the general mobile communication terminal 13 (T1). As described above, the URL information is obtained by transmitting the image data for access to the image domain server 26 and accessed, or the URL information is obtained and accessed by the QR code as described above, or the URL information is directly input. And either way of accessing.

  Next, the web server 20 discriminates the carrier and model of the general mobile communication terminal 13 that has accessed by the model discriminating means 30 (T2). And the content data which can be browsed with the general portable communication terminal 13 accessed by the content data search means 32 of the web server 20 are searched (T3). The content data for each carrier and each model is created when the system mobile communication terminal 10 is accessed at the time of initial registration. The content data searched by the content data search means 32 is read by the content data reading means 34 (T4), and a website that can be browsed by the general mobile communication terminal 13 is created by the website creation means 40. It is transmitted to the terminal 13 (T5).

  The accessed user can browse the website, and designates or selects a moving image to be browsed on the website (T6). The designation or selection is performed by, for example, clicking a thumbnail displayed on the website. Then, the web server 20 searches the moving image data search means 36 for moving image data that can be browsed by the general mobile communication terminal 13 accessed by the moving image data search means 36 (T7), and reads it by the moving image data reading means 38 ( T8), and transmit to the accessed general mobile communication terminal 13. In this way, the moving image designated by the general portable communication terminal 13 can be browsed (T9). Further, if there is a moving image to be browsed (T10), the same operation may be performed by returning to the point C in the flowchart.

  Therefore, in the above configuration, regardless of the carrier and model of the general mobile communication terminal that has accessed, any mobile communication terminal can browse the website and download and / or upload video data. It should be noted that the moving image data downloaded to the mobile communication terminal is not stored, but streaming for simply browsing a moving image is also possible. Further, as shown in the prior art, after determining the carrier of the mobile communication terminal, the moving image generation parameter corresponding to the determined model is determined, and a moving image file for download that satisfies the moving image generation parameter is generated. There is no need, and since the moving image data is encoded in advance for every carrier and every model, the moving image can be viewed immediately, and the moving image distribution server can be configured at low cost.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the database is configured to exist only in the image domain server, but may be configured to be owned by each server as a storage unit. Alternatively, each storage unit may have a database.
