1 is a diagram showing an overview of a remote conference system 1 and an electrical configuration of a server 11 and a conference device 15. It is a figure which shows the display image 371. FIG. It is a figure which shows the display image 3711. FIG. It is a figure which shows the display image 372. FIG. It is a figure which shows the 1st table 241. FIG. It is a figure which shows the 2nd table 242. FIG. It is a figure which shows the 3rd table 243. It is a flowchart of a main process. It is a flowchart of a main process, Comprising: FIG. 8 is a continuation. FIG. 9 is a flowchart of the main process, which is a continuation of FIG. It is a flowchart of an authority acquisition process. It is a flowchart of a recording process.

  The remote conference system 1 will be described with reference to FIG. The remote conference system 1 is a system for conducting a remote conference between remote bases. The remote conference system 1 includes a server 11 and conference devices 12, 13, and 14 (hereinafter collectively referred to as “conference device 15”). The server 11 and the conference apparatus 15 are connected via the network 20 so that they can communicate with each other. An example of the server 11 is a multipoint connection unit (MCU). An example of the conference device 15 is a PC.

  The conference device 15 transmits a plurality of types of media data (hereinafter simply referred to as “media”) to the server 11 during a remote conference. Examples of the plurality of types of media include photographed image media, shared material media, and chat media. The captured image media includes one or more image data captured by the camera 361 of the conference apparatus 15. The shared material medium includes one or more pieces of shared material image data stored in the HDD 24 of the conference apparatus 15. The chat media includes one or more data of images (chat images) including text input via the keyboard 362 during the chat.

  The server 11 synthesizes images based on the image data included in the media received from the conference device 15 and creates a display image. The server 11 transmits a display image to the conference device 15 via the network 20. The conference device 15 displays the received display image on the display 37. Hereinafter, an image based on image data included in a medium is simply referred to as “image based on media”.

  FIG. 2 shows a display image 371 that is an example of a display image displayed on the display 37 of the conference apparatus 15. The display image 371 includes a captured image window 41 based on the captured image media, a shared material window 42 based on the shared material media, and a chat image window 43 based on the chat media. The user of the conference apparatus 15 can recognize the state of the other users of the other conference apparatuses 15 by browsing the window 41 of the captured image. In addition, the user can conduct a remote conference while browsing the shared material window 42 by referring to the shared material. Also, the user can chat with other users by browsing the chat image window 43.

  Note that the windows 41, 42, and 43 of the display image 371 are not fixed, and change according to the type and number of media transmitted from the conference device 15. For example, when only the captured image media is transmitted from each of the conference devices 12, 13, and 14 and the shared material media and the chat media are not transmitted, the server 11 displays each of the display areas of the display 37 divided into three in the horizontal direction. A display image in which each of the three captured image windows is arranged in the region is created.

  When the chat is performed only between the conference apparatuses 12 and 13, the display screen 371 transmitted to the conference apparatuses 12 and 13 includes the chat image window 43, but the conference apparatus 14 not participating in the chat. The chat image window 43 is not included in the display image transmitted to. Therefore, as shown in FIG. 3, a display image 3711 that does not include the chat image window 43 is displayed on the display 37 of the conference apparatus 14. Compared with the display image 371 of FIG. 2, the layout of the window 41 of the photographed image is changed, and the window 42 of the shared material is enlarged. Further, the conference apparatus 15 moves the captured image window 41, the shared material window 42, and the chat image window 43 to positions corresponding to the input operation based on the input operation to the conference apparatus 15.

  Further, the server 11 can store the media and information related to the media so that the display image during the remote conference can be browsed after the remote conference ends. For example, the server 11 can provide the conference apparatus 15 with the display image 371 during the remote conference shown in FIG. The conference apparatus 15 can use the display image as history information (minutes) during the remote conference by displaying the provided display image on the display 37. Hereinafter, the display image provided to the conference device 15 after the remote conference is also referred to as a “minute image”.

  Further, the server 11 can set permission for browsing of photographed images, shared materials, and chat images included in the minutes image provided to the conference device 15 after the end of the remote conference for each conference device 15. For example, the server 11 can permit the conference devices 12 and 14 to browse the shared material in the minutes image and prohibit the conference device 13. When the browsing of the image is prohibited, the server 11 provides the conference device 15 with the minutes image obtained by superimposing the mask image on the image for which browsing is prohibited.

  For example, a case where browsing of shared materials is prohibited for the conference apparatus 13 will be described as an example. FIG. 4 shows a display image 372 provided to the conference device 13 after the end of the remote conference. Since browsing of the shared material is prohibited, the mask image 44 is displayed in an overlapping manner on the shared material window 42. The mask image 44 is a rectangular image filled with a single color (for example, black). When the mask image 44 is superimposed on the shared material window 42, the shared material becomes invisible. In this manner, the server 11 can prohibit the user of the conference device 13 from browsing the shared material.

  Further, for example, a case where browsing of the shared material is prohibited for the conference apparatus 14 is taken as an example. In this case, a display image in which a mask image is superimposed on the shared material window 42 in the display image 3711 shown in FIG. 3 is provided to the conference apparatus 14 as a minutes image. As described above, even if the layout of the display image is different for each conference device 15, the server 11 can appropriately prohibit the browsing of a specific image by the mask image corresponding to the layout of each display image. .

  The electrical configuration of the server 11 will be described. The server 11 includes a CPU 21 that controls the server 11. The CPU 21 is electrically connected to the ROM 22, RAM 23, hard disk drive (HDD) 24, communication interface (hereinafter referred to as “communication I / F”) 25, and drive device 26. The ROM 22 stores a boot program, BIOS, and the like. The RAM 23 stores a timer, a counter, and temporary data. The HDD 24 stores a program (recording program) for the CPU 21. The HDD 24 stores a first table 241 (see FIG. 5, described later), a second table 242 (see FIG. 6, described later), and a third table (see FIG. 4, described later). The HDD 24 may have another configuration as long as it is a computer-readable storage medium. The communication I / F 25 communicates with the conference device 15 via the network 20. The drive device 26 reads information stored in the storage medium 261. For example, when the server 11 is set up, the recording program stored in the storage medium 261 is read by the drive device 26 and stored in the HDD 24. The storage medium 261 is a computer-readable storage medium such as an optical medium or a semiconductor memory. Note that a computer-readable recording medium may not include a temporarily transmitted signal. The computer-readable recording medium may be a non-transitory recording medium. A non-temporary recording medium does not include a temporary signal. The non-temporary recording medium may be any recording medium that can record information regardless of the period in which the information is stored.

  The CPU 21 of the server 11 may receive a recording program as a transmission signal via the network 20 and store it in the HDD 24. In this case, the recording program is stored in a storage medium such as an HDD provided in a server (not shown) connected via the network 20.

  The electrical configuration of the conference apparatus 15 will be described. The conference device 15 includes a CPU 31 that controls the conference device 15. The CPU 31 is electrically connected to the ROM 32, RAM 33, HDD 34, communication I / F 35, external interface (hereinafter referred to as “external I / F”) 36, display 37, speaker 38, and microphone 39. The ROM 32 stores a boot program, BIOS, and the like. The RAM 33 stores timers, counters, and temporary data. The HDD 34 stores a control program for the CPU 31. The communication I / F 35 communicates with the server 11 via the network 20. A camera 361 and a keyboard 362 can be connected to the external I / F 36.

  The first table 241 will be described with reference to FIG. The first table 241 includes a conference ID, a user ID, a role, a photographed image media name and a photographed image display area, a shared document medium name and a shared document display area, and a chat media name and a chat image display area. Remember. The conference ID is identification information for identifying the remote conference. The user ID is identification information for identifying the conference device 15 participating in the remote conference identified by the corresponding conference ID. The role indicates a role in the remote conference assigned to the user who uses the conference device 15 identified by the corresponding user ID. As the role, for example, any one of “chairperson”, “presenter”, and “participant” is stored.

  The captured image display area, the shared material display area, and the chat image display area are the lower left and upper right areas of the display 37 on which the captured image, shared material, and chat image windows are displayed, respectively. Indicates the coordinate information of the vertex. In the case of FIG. 5, since the names “s1, s2, s3” of the three photographed image media are stored, three display areas ((x9, xa) (xb, xc) are displayed as the photographed image display areas. (Display area of the photographed image with name s1), (y9, ya) (yb, yc) (Display area of the photographed image with name s2), (z9, za) (zb, zc) (Display of the photographed image with name s3) Area)) is stored.

  The first table 241 stores information related to the display image transmitted to the conference device 15. The first table 241 in FIG. 5 corresponds to the display image 371 in FIG. 2 and the display image 3711 in FIG. Based on the first table 241, the CPU 51 creates a display image 371 (see FIG. 2) to be transmitted to the conference apparatuses 12 and 13, and creates a display image 3711 (see FIG. 3) to be transmitted to the conference apparatus 14. To do. The display images 371 and 3711 have different layouts for the captured image window and the shared material window. The display image 371 includes a chat image window, whereas the display image 3711 does not include a chat image window. Therefore, in the first table 241, the display area for the captured image and the shared material corresponding to the user IDs 12 and 13 is different from the display area for the captured image and the shared material corresponding to the user ID 14. In addition, the chat image name and display area are associated with the user IDs 12 and 13, whereas the chat image name and display area are not associated with the user ID 14.

  The second table 242 will be described with reference to FIG. The second table 242 includes a level table 2421 and an authority table 2422. The level table 2421 stores roles and levels. “Chairman”, “presenter”, “participant”, and “non-participant” are stored as roles. The level indicates the degree of media viewing authority permitted to the conference device 15 used by the user of the corresponding role. In the case of FIG. 6, levels are set in the order of “chairperson”, “presenter”, “participant”, and “nonparticipant”, “chairperson” has the highest viewing authority, and “nonparticipant” has the lowest viewing authority.

  The authority table 2422 stores media types and browsing authorities. As the media type, “photographed image”, “shared material”, and “chat” are stored. The viewing authority indicates a role capable of viewing a corresponding type of image. In the case of FIG. 6, “participant or higher”, “presenter or higher”, and “arbitrary” are associated with each type of “photographed image”, “shared material”, and “chat”. When the viewing authority is “participant or higher”, the image can be viewed on the conference device 15 used by the users of the roles “chairman”, “presenter”, and “participant” whose level is “participant” or higher. This indicates that browsing of images is prohibited for the conference apparatus 15 that is permitted and used by the user of the role “non-participant”. When the viewing authority is “presenter or higher”, image browsing is permitted to the conference device 15 used by the users of the roles “chairman” and “presenter” whose level is “presenter” or higher, and the role This indicates that browsing of images is prohibited for the conference device 15 used by users of “participants” and “non-participants”. When the viewing authority is “arbitrary”, image browsing is permitted to the conference device 15 having the user ID in which the corresponding name and display area are stored among the user IDs of the first table 241, and the first table. Of the user IDs 241, viewing of images is prohibited for the conference device 15 having a user ID for which the corresponding name and display area are not stored.

  In FIG. 6, one second table 242 is shown, but actually, a different second table 242 is created for each conference ID. That is, a different browsing authority is set for each remote conference to be executed. Although details will be described later, the information stored in the second table 242 is transmitted to the server 11 from the conference device 15 used by the user in charge of the chairman among the conference devices 15 participating in the remote conference.

  The third table 243 will be described with reference to FIG. The third table 243 is a table stored in order to create a mask image and to allow a display image during a remote conference to be viewed as a minutes image. FIG. 7 shows three third tables 2431, 2432, and 2433 created at times “0:00:00”, “0:20:41”, and “0:35:27”. The third tables 2431, 2432, 2433 store information at each time, and are all stored in the HDD 24.

  The third table 243 stores time information, media type, name, permission information for each user ID, and display area (mask area) for each user ID. The time information is information corresponding to the time when the third table 243 is created. The time indicated by the time information also represents the time when the media is received from the conference device 15. The permission / refusal information is information indicating whether the conference device 15 identified by the corresponding user ID is permitted or prohibited from browsing the corresponding type of image. The display area (mask area) indicates coordinate information of the lower left and upper right vertices of a display area where a corresponding type of media is displayed or a mask area (described later) where a mask image 44 (see FIG. 4) is displayed. .

  A main process and a recording process executed by the CPU 21 of the server 11 will be described with reference to FIGS. The main process is started when the CPU 21 executes a recording program stored in the HDD 24 when the server 11 is powered on. The storage process is started when the CPU 21 executes the recording program stored in the HDD 24 in S55 of the main process (see FIG. 9). The main process and the storage process are executed in parallel.

  The main process will be described with reference to FIG. The CPU 21 determines whether connection request data has been received from the conference device 15 (S11). The connection request data is transmitted from the conference device 15 to the server 11 when the CPU 21 receives an input operation requesting participation in the remote conference. The connection request data includes the user ID of the conference device 15 and the conference ID of the remote conference that requests participation. When the CPU 21 determines that the connection request data has been received (S11: YES), the CPU 21 determines whether the conference ID included in the connection request data is stored in the first table 241. When the conference ID included in the connection request data is not stored in the first table 241, the CPU 21 stores the conference ID and the user ID included in the connection request data in association with each other in the first table 241. When the conference ID is first stored in the first table 241, the CPU 21 stores “chairperson” in association with the role (S12). The CPU 21 establishes a session with the conference device 15 that has transmitted the connection request data and establishes a connection state, thereby starting a remote conference with the conference device 15 that has transmitted the connection request data (S13). At this time, only the conference device 15 that transmitted the connection request data is participating in the remote conference.

  On the other hand, when the conference ID included in the connection request data is already stored in the first table 241, the CPU 21 associates the user ID with the conference ID included in the connection request data and stores the user ID in the first table 241 ( S12). The CPU 21 transmits role request data for inquiring the role of the conference apparatus 15 that transmitted the connection request data to the conference apparatus 15 identified by the user ID associated with “chairperson” as the role in the first table 241. To do. The role request data includes the user ID of the conference device 15 that transmitted the connection request data. The conference device 15 that has received the role request data transmits role response data including the role of the conference device 15 identified by the user ID included in the role request data to the server 11. The CPU 21 of the server 11 receives role response data. The CPU 21 stores the role included in the role response data in the first table 241 in association with the user ID of the conference device 15 that transmitted the connection request data. The CPU 21 establishes a session with the conference device 15 that has transmitted the connection request data and establishes a connection state, thereby starting a remote conference with the conference device 15 that has transmitted the connection request data (S13). Since a plurality of user IDs are associated with the same conference ID in the first table 241, a plurality of conference devices 15 identified by the plurality of user IDs are in a state of participating in the remote conference. . The CPU 21 executes authority acquisition processing (see FIG. 11) (S15).

  The authority acquisition process will be described with reference to FIG. The CPU 21 transmits authority request data for inquiring browsing authority to the conference apparatus 15 identified by the user ID associated with “chairman” as a role in the first table 241 (S91). The conference apparatus 15 that has received the authority request data receives information indicating the correspondence between roles and levels (information stored in the level table 2421 (see FIG. 6)) and information indicating the correspondence between types and viewing authorities. Authority response data including (information stored in the authority table 2422 (see FIG. 6)) is transmitted to the server 11. The CPU 21 of the server 11 receives authority response data (S93).

  CPU21 memorize | stores the information which shows the correspondence of a role and a level in the level table 2421 of the 2nd table 242 among the information contained in the received authority response data (S95). CPU21 memorize | stores the information which shows the correspondence of a classification and browsing authority among the information contained in the received authority response data in the authority table 2422 of the 2nd table 242 (S95). The CPU 21 ends the authority acquisition process and returns the process to the main process (see FIG. 8). As shown in FIG. 8, the CPU 21 returns the process to S11 after the end of the authority acquisition process (S15).

   When the CPU 21 determines that the connection request data is not received in S11 (S11: NO), the captured image transmitted from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether reception of image data included in the medium has been started (S17). When the CPU 21 determines that the reception of the image data included in the photographic image media has been started (S17: YES), the conference ID corresponding to the user ID of the conference device 15 that has transmitted the photographic image media in the first table 241. All user IDs associated with are identified as participation IDs. CPU21 memorize | stores the name of the picked-up image media containing the image data which started reception in the 1st table 241 corresponding to participation ID (S19). The conference device 15 transmits a plurality of image data based on the same photographed image media by streaming. For this reason, the CPU 21 repeatedly receives the image data transmitted from the conference device 15 as image data included in the photographic image medium whose name is stored in the first table 241.

  The CPU 21 creates a display image including a captured image window based on the received captured image media for each conference device 15 identified by the participation ID. The CPU 21 specifies the display area of the captured image window in the created display image for each participation ID, and stores it in the first table 241 in association with the participation ID. The CPU 21 transmits the created display image to the conference device 15 identified by the participation ID (S21). Note that the CPU 21 continuously receives image data from the conference apparatus 15, and therefore updates the captured image included in the display image every time image data is received. The CPU 21 repeatedly transmits the display image with the captured image updated to the conference device 15 identified by the participation ID. CPU21 returns a process to S11.

  The conference device 15 that has received the display image transmitted from the server 11 displays the received display image on the display 37. Since the display image includes at least a captured image, the user of the conference device 15 can visually check the state of the other users of the other conference devices 15 participating in the remote conference.

  If the CPU 21 determines in S17 that it has not received the photographed image media (S17: NO), it receives the shared material media from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether it has been done (S23). If the CPU 21 determines that the shared material medium has been received (S23: YES), the CPU 21 of the first table 241, all the correspondences associated with the conference ID corresponding to the user ID of the conference device 15 that has transmitted the shared material medium. The user ID is specified as the participation ID. The CPU 21 stores the received name of the shared material medium in the first table 241 in association with the participation ID (S25). Further, the CPU 21 stores the received shared material medium in the HDD 24 in association with the name of the first table 241.

  The CPU 21 creates a display image including a shared material window based on the received shared material medium for each conference device 15 identified by the participation ID. The CPU 21 specifies the display area of the shared material window in the created display image for each participation ID, and stores the display area in the first table 241 in association with the participation ID. The CPU 21 transmits the created display image to the conference device 15 identified by the participation ID (S27). CPU21 returns a process to S11.

  The conference device 15 that has received the display image transmitted from the server 11 displays the received display image on the display 37. Since the display image includes at least the shared material, the user of the conference device 15 can perform the remote conference while referring to the shared material.

  When the CPU 21 determines in S23 that the shared material medium has not been received (S23: NO), the CPU 21 displays the shared material from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether sharing end data for termination is received (S29). The sharing end data includes the name of the shared material medium. When it is determined that the sharing end data has been received (S29: YES), the CPU 21 deletes the name included in the sharing end data and the corresponding display area from the first table 241 (S31). The CPU 31 creates a display image from which the shared material is deleted. The CPU 21 transmits the created display image to the conference device 15 identified by the deleted name and the user ID associated with the display area (S33). CPU21 returns a process to S11.

  The conference device 15 that has received the display image transmitted from the server 11 displays the received display image on the display 37. Since the display image does not include the shared material, the user of the conference device 15 cannot refer to the shared material.

  As shown in FIG. 9, when the CPU 21 determines in S29 (see FIG. 8) that it has not received the sharing end data (S29: NO), the conference identified by the user ID stored in the first table 241. It is determined whether reception of image data included in the chat media transmitted from any of the devices 15 is started (S41). The chat media includes a plurality of user IDs (hereinafter referred to as “chat IDs”) of a plurality of conference apparatuses 15 participating in the chat. When the CPU 21 determines that the reception of the image data included in the chat media is started (S41: YES), the name of the chat media including the image data that has started reception is associated with the chat ID in the first table 241. Store (S43). The conference device 15 transmits a plurality of image data based on the same chat media every time the text indicating the chat content is updated. For this reason, the CPU 21 repeatedly receives the image data transmitted from the conference device 15 as the image data included in the chat media whose names are stored in the first table 241.

  The CPU 21 creates a display image including a chat image window based on the received chat media for each conference device 15 identified by the chat ID. The CPU 21 specifies the display area of the chat image window in the created display image, and stores it in the first table 241 in association with the chat ID. CPU21 transmits the produced display image to the conference apparatus 15 identified by chat ID (S45). Note that the CPU 21 continuously receives image data from the conference device 15, and therefore updates the chat image included in the display image every time image data is received. CPU21 transmits repeatedly the display image in which the chat image was updated to the conference apparatus 15 identified by chat ID. The CPU 21 returns the process to S11 (see FIG. 8).

  For example, when a chat is performed between the conference apparatuses 12 and 13, display images to be displayed on the respective displays 37 of the conference apparatuses 12 and 13 are created. The display area of the chat image window in the generated display image is specified. The identified display area is stored in the first table 241 in association with each of the user IDs 12 and 13. The created display image is transmitted to the conference apparatuses 12 and 13. In this case, since the conference device 14 does not participate in the chat, the name and display area of the chat media are not associated with the user ID 14 as shown in FIG. Further, the created display image is not transmitted to the conference apparatus 14.

  If the CPU 21 determines that the reception of the image data included in another chat media has not started after the reception of the image data included in the chat media in S41 (S41: NO), it is identified by the chat ID. It is determined whether chat end data for ending the chat has been received from any of the conference devices 15 to be performed (S47). The chat end data includes a chat ID. When it is determined that the chat end data has been received (S47: YES), the CPU 21 ends the reception of the image data included in the chat media started in S41. The CPU 21 deletes the name of the chat media associated with the chat ID included in the chat end data and the corresponding display area from the first table 241 (S49). The CPU 31 creates a display image from which the chat image window has been deleted. CPU21 transmits the produced display image to the conference apparatus 15 identified by chat ID (S51). The CPU 21 returns the process to S11 (see FIG. 8).

  The conference device 15 that has received the display image transmitted from the server 11 displays the received display image on the display 37. Since the display image does not include the chat image window, the user of the conference device 15 cannot continue the chat.

  If the CPU 21 determines in S47 that the chat end data has not been received (S47: NO), it receives the recording start data from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether or not (S53). The recording start data is transmitted from the conference device 15 to the server 11 in response to the CPU 31 of the conference device 15 receiving an input operation requesting the start of recording history information. When the CPU 21 determines that the recording start data has been received (S53: YES), the CPU 21 starts the recording process (see FIG. 12) (S55). Details of the recording process will be described later. When the CPU 21 receives the image data included in the media in order to use the image based on the media (any one of the captured image media, the shared media, and the chat media) received from the conference device 15 as the minutes image, A process of storing the received image data in the HDD 24 is started (S56). The CPU 21 returns the process to S11 (see FIG. 8).

  When the CPU 21 determines that the recording start data is not received in S53 (S53: NO), the CPU 21 receives the recording end data from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether it has been (S57). The recording end data is transmitted from the conference device 15 to the server 11 in response to the CPU 31 of the conference device 15 receiving an input operation requesting the end of recording history information. When determining that the recording end data has been received (S57: YES), the CPU 21 stores an end flag in the RAM 23 in order to end the recording process started in S55 (S59). If the CPU 21 detects an end flag stored in the RAM 23 in the recording process (see FIG. 12) (S101: YES, see FIG. 12), the CPU 21 ends the recording process. The CPU 21 ends the storage of the image data started in S56 (S60). The CPU 21 returns the process to S11 (see FIG. 8).

  As shown in FIG. 10, when it is determined in S57 (see FIG. 8) that the recording end data has not been received (S57: NO), the CPU 21 selects “chairperson” from the user IDs stored in the first table 241. It is determined whether authority change data has been received from the conference device 15 identified by the user ID associated with the role (S61). The authority change data is transmitted from the conference apparatus 15 to the server 11 in response to the CPU 31 of the conference apparatus 15 receiving an input operation for changing the browsing authority. The authority change data includes information indicating the correspondence between roles and levels, and information indicating the correspondence between types and browsing authorities. When the CPU 21 determines that the authority change data has been received (S61: YES), the level table of the second table 242 indicates information indicating the correspondence between roles and levels among the information included in the received authority change data. 2421 to change the role and level. CPU21 memorize | stores the information which shows the correspondence of a classification and browsing authority among the information contained in the received authority response data in the authority table 2422 of the 2nd table 242, and changes a classification and browsing authority (S63). . The CPU 21 returns the process to S11 (see FIG. 8).

  When the CPU 21 determines in S61 that the authority change data has not been received (S61: NO), the CPU 21 receives the position change data from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether or not (S71). The position change data is transmitted from the conference apparatus 15 to the server 11 in response to the CPU 31 of the conference apparatus 15 receiving an input operation for changing the display position of a specific window in the display image displayed on the display 37. . The position change data includes a type, a name, and a display area after change. When the CPU 21 determines that the position change data has been received (S71: YES), the display area obtained in association with the type and name included in the position change data in the first table 241 is included in the position change data. The display area is changed and stored (S73).

  The CPU 21 creates a display image in which an image display area based on the type and name media included in the position change data is changed to a display area included in the position change data. The CPU 21 transmits the created display image to the conference device 15 identified by the user ID associated with the changed display area (S74). The CPU 21 returns the process to S11 (see FIG. 8).

  When the CPU 21 determines that the position change data is not received in S71 (S71: NO), the CPU 21 receives the conference withdrawal data from any of the conference devices 15 identified by the user ID stored in the first table 241. It is determined whether it has been (S75). The conference withdrawal data is transmitted from the conference device 15 to the server 11 in response to the CPU 31 of the conference device 15 receiving an input operation for withdrawal from the participating remote conference. The conference withdrawal data includes the user ID of the conference device 15 that is the transmission source. When determining that the conference withdrawal data has been received (S75: YES), the CPU 21 deletes the user ID included in the conference withdrawal data from the first table 241 (S77). The CPU 21 deletes the role associated with the deleted user ID and the names and display areas of the photographed image media, shared material media, and chat media from the first table 241 (S77).

  The CPU 21 creates a display image based on the information stored in the first table 241 after deletion. For example, when the conference device 14 withdraws from the remote conference while the conference devices 12, 13, 14 are participating in the remote conference, the windows of the captured images received from the conference device 14 are displayed on the conference devices 12, 13, respectively. Is deleted from the display image transmitted to, and the window positions of the remaining captured images are adjusted. The CPU 21 specifies the display area of the captured image window in the generated display image, stores it in the first table 241, and changes it. The CPU 21 transmits the created display image to the conference device 15 identified by the user ID associated with the conference ID corresponding to the deleted user ID (S79). The CPU 21 returns the process to S11 (see FIG. 8).

  CPU21 returns a process to S11 (refer FIG. 8), when it is judged that the conference withdrawal data is not received (S75: NO).

  The storage process will be described with reference to FIG. The CPU 21 determines whether to end the recording process (S101). When the end flag is stored in the RAM 23, the CPU 21 determines to end the recording process (S101: YES), and ends the recording process. The end flag is stored in the RAM 23 in S59 of the main process (see FIG. 9). If the end flag is not stored in the RAM 23, the CPU 21 determines to continue the recording process (S101: NO).

  The CPU 21 determines whether a medium has been added to the first table 241 or a medium stored in the first table 241 has been changed (S105). When reception of image data included in the medium is started in the main process (see FIG. 8) (S17, S23, S41), the name of the medium is stored in the first table 241 (S19, S25, S43). Therefore, the CPU 21 determines that the medium is added or changed when the name is added to the first table 241 or when the name is changed. Further, when the sharing of the shared material medium is terminated in the main process (S29), the name of the received shared material medium is deleted from the first table 241 (S31). If it is determined that the chat has ended in the main process (S47), the name of the received chat media is deleted from the first table 241 (S49). Therefore, when the name of the first table 241 is deleted, the CPU 21 determines that the medium has been changed.

  When the CPU 21 determines that the medium has been added or changed (S105: YES), the CPU 21 executes an authority acquisition process (see FIG. 11) (S106). The second table 242 (level table 2421 and authority table 2422) is updated by the authority acquisition process. A description of the authority acquisition process is omitted. The CPU 21 acquires all the user IDs associated with the conference ID corresponding to the added or changed name and the names and types of all the media based on the first table 241 (S107).

  Based on the second table 242, the CPU 21 specifies permission / denial information for each user ID for each acquired type. The specific method of specifying permission / denial information is as follows. The CPU 21 specifies a role (any one of “chairman”, “presenter”, and “participant”) corresponding to the user ID acquired in S107 in the first table 241. The CPU 21 assigns a viewing authority (any one of “participant or higher”, “presenter or higher”, or “arbitrary”) corresponding to the type acquired in S107 (any one of “photographed image”, “shared material”, and “chat”). This is specified based on the table 2422. Based on the specified role and browsing authority, the CPU 21 specifies permission information indicating whether or not browsing of the media is permitted for each user ID. For example, when the type is “photographed image”, since the viewing authority is “participant or higher”, media viewing is permitted for the conference device 15 corresponding to the role of “chairperson”, “presenter”, and “participant”. The browsing of the media with respect to the conference device 15 corresponding to “non-participant” is prohibited. Also, for example, when the type is “shared material”, the viewing authority is “presenter or higher”, so that the media browsing to the conference device 15 corresponding to the role of “chairperson” or “presenter” is permitted, and “participation” Viewing of the media with respect to the conference apparatus 15 corresponding to “person” and “non-participant” is prohibited. The CPU 21 associates permission / rejection information (any of “permitted” and “prohibited”) specified for each user ID with the type and name (S108). The above processing is executed for all acquired types.

  The CPU 21 acquires the current time from the OS as the time when the medium is added or changed. Since the main process and the recording process are executed in parallel, reception of image data included in the medium (any one of the photographed image medium, the shared material medium, and the chat medium) is started in the main process. The timing when the name of the medium is stored in the table 241 and the timing when it is determined that the medium is added or changed in S105 of the recording process are substantially the same. The CPU 21 further associates the time information corresponding to the acquired time with the type, name, and permission / rejection information associated in S108 (S109).

  Based on the first table 241, the CPU 21 acquires a display area corresponding to the name acquired in S107 for each user ID (S110). The CPU 21 creates a mask image based on the display area corresponding to the permission / prohibition information “prohibition” in the acquired display area (see S113, described later). Therefore, the display area corresponding to the permission / prohibition information “prohibited” in the acquired display area corresponds to the area (mask area) where the mask image is displayed. The CPU 21 further associates the acquired display area for each user ID with time information, type, name, and permission / rejection information (S110). The CPU 21 stores the associated time information, type, name, permission / denial information, and display area in the HDD 24 as the third table 243 (S111).

  The CPU 21 creates a mask image based on a display area (mask area) associated with permission / prohibition information of “prohibited” (S113). Specifically, the CPU 21 creates, as a mask image, an image in which a rectangular area indicated by a display area (mask area) associated with permission / inhibition information of “prohibited” is filled with a single color (for example, black). The CPU 21 creates a display image by arranging an image based on the media stored in the HDD 24 based on S56 (see FIG. 9) in the display area of the third table 243. The CPU 21 generates a minutes image including the created display image and mask image (S113). The CPU 21 returns the process to S101.

  The CPU 21 can display the generated minutes image on the display 37 of the conference device 15 after the end of the remote conference. When displaying the minutes image on the display 37 of the conference device 15 having the user ID associated with the permission / prohibition information of “prohibited”, the CPU 21 displays the corresponding mask image superimposed on the display image. Thereby, the CPU 21 can conceal the specific image included in the display image with the mask image.

  For example, the case where it is determined that chat media has been added at time “0:35:27” (S105: YES) is taken as an example, and the case where the third table 2433 of FIG. 7 is created will be specifically described. .

  The names “s1, s2, s3”, the type “captured image”, and the user IDs “12”, “13”, and “14” are acquired from the first table 241 (S107). The roles “chairman”, “participant”, and “presenter” corresponding to the user IDs “12”, “13”, and “14” are specified based on the first table 241. The viewing authority “participant or higher” corresponding to the type “captured image” is specified based on the authority table 2422. Since the roles “chairperson”, “participant”, and “presenter” all fall under “participants and higher”, it is determined that all of the user IDs “12”, “13”, and “14” are permitted to view the captured image. The “Permitted” is specified as permission / denial information of the user IDs “12”, “13”, and “14” (S108). Further, “prohibited” is specified as permission / inhibition information corresponding to “non-participant” (S108).

  In addition, the name “t”, the type “shared material”, and the user IDs “12”, “13”, and “14” are acquired from the first table 241 (S107). The viewing authority “presenter or higher” corresponding to the type “shared material” is specified based on the authority table 2422. Since the roles “chairman” and “presenter” correspond to “presenter or higher”, it is determined that the user IDs “12” and “14” are permitted to view captured images. On the other hand, since the role “participant” does not correspond to “presenter or higher”, it is determined that the user ID “13” is prohibited from browsing the captured image. “Permitted” is specified as the permission information of the user IDs 12 and 14, and “Prohibited” is specified as the permission information of the user ID 13 (S108). Further, “prohibited” is specified as permission / inhibition information corresponding to “non-participant” (S108).

  Further, the name “u”, the type “chat”, and the user IDs “12”, “13”, and “14” are acquired from the first table 241 (S107). The browsing authority “arbitrary” corresponding to the type “chat” is specified based on the authority table 2422. When the viewing authority is “arbitrary”, the user IDs “12” and “13” associated with the name “u” in the first table 241 (that is, the user IDs of the conference apparatuses 12 and 13 performing the chat) On the other hand, browsing of the chat image is permitted, and browsing of the chat image is prohibited for the user ID “14” of the conference apparatus 14 that is not chatting. Accordingly, “permitted” is specified as the permission information of the user IDs 12 and 13, and “prohibited” is specified as the permission information of the user ID 14 (S108). Further, “prohibited” is specified as permission / inhibition information corresponding to “non-participant” (S108).

  The time “0:35:27” is specified (S109). Based on the first table 241, the display areas (x9, xa) (xb, xc) (y9, ya) (yb, yc) of the user IDs “12” and “13” corresponding to the names “s1, s2, s3” ) (Z9, za) (zb, zc) are specified as display areas corresponding to the user IDs “12” “13” and “non-participant” (S110). Since “non-participant” is associated with permission / prohibition information of “prohibited”, the display area (x9, xa) (xb, xc) (y9, ya) (yb) corresponding to “non-participant” , Yc) (z9, za) (zb, zc) are used as mask regions. That is, a mask image is created in the display area (mask area) in S113 described later. Further, the display area (x5, x6) (x7, x8) (y5, y6) (y7, y8) (z5, z6) (z7, z8) of the user ID “14” corresponding to the name “s1, s2, s3” ) Is identified (S110).

  Similarly, the display areas (8, 0) (16, 9) of the user IDs “12”, “13” and “non-participant” corresponding to the name “t” are specified (S110). Since the user ID “13” and “non-participant” are associated with permission / prohibition information of “prohibited”, the display area (8, 0) corresponding to the user ID “13” and “non-participant”. (16, 9) is used as a mask area. Further, the display area (6, 0) (16, 12) of the user ID “14” corresponding to the name “t” is specified (S110). Similarly, the display areas (0, 5) (8, 9) of the user IDs “12”, “13” and “non-participant” corresponding to the name “u” are specified (S110). Since “non-participant” is associated with permission / prohibition information of “prohibited”, display areas (0, 5) (8, 9) corresponding to “non-participant” are used as mask areas. .

  The specified information is associated and stored in the HDD 24 as the third table 2433 (S111). Specifically, the type “captured image”, name “s1, s2, s3”, permission information “permitted” (user ID “12” “13” “14”), permission information “prohibited” (“non-participation” Display area (mask area) (x9, xa) (xb, xc) (y9, ya) (yb, yc) (z9, za) (zb, zc) (user IDs “12” “13” “ Non-participant ") and display area (mask area) (x5, x6) (x7, x8) (y5, y6) (y7, y8) (z5, z6) (z7, z8) (user ID" 14 " ), Type “shared material”, name “t”, permission information “permitted” (user ID “12” “14”), permission information “prohibited” (user ID “13” “non-participant”), Display area (mask area) (8, 0) (16, 9) (user ID “12” “13” “non-participant”); Set area (mask area) (6, 0) (16, 12) (user ID “14”), type “chat”, name “u”, permission information “permitted” (user ID “12” “13” )), Permission information “prohibited” (user ID “14”, “non-participant”), and display area (mask area) (0, 5) (8, 9) (user ID “12” “13” “ The group of “non-participants”) is associated with the time information “0:35:27” and stored in the HDD 24 as the third table 2432 (S111).

  Next, the case where a mask image is created based on the created third table 2433 and a minutes image is generated (S113) will be specifically described. The CPU 21 refers to the third table 2433. The type “captured image” and the name “s1 / s2 / s3” are associated with “prohibited” as permission / inhibition information corresponding to “non-participant”. Accordingly, (x9, xa) (xb, xc) (y9, ya) (yb, yc) (z9, za) (zb, zc) associated with “non-participant” in the display area (mask area). A mask image arranged in the area of) is created. Next, the CPU 21 acquires the captured image media with the names “s1”, “s2”, and “s3” from the HDD 24. The CPU 21 arranges the captured image with the name “s1” in the display area (x9, xa) (xb, xc), and arranges the captured image with the name “s2” in the display area (y9, ya) (yb, yc). Then, the captured image with the name “s3” is arranged in the display area (z9, za) (zb, zc) to create a display image. The mask image created in the mask area (x9, xa) (xb, xc) (y9, ya) (yb, yc) (z9, za) (zb, zc) is a captured image arranged in the display image. Can be concealed.

  Further, the type “shared material” and the name “t” are associated with t “prohibited” as permission / inhibition information corresponding to the user ID “13” and “non-participant”. Therefore, a mask image arranged in the area of (8, 0) (16, 9) associated with the user ID “13” and “non-participant” in the display area (mask area) is created. Next, the CPU 21 acquires the shared material medium with the name “t” from the HDD 24. In addition to the photographed image, the CPU 21 arranges the shared material with the name “t” in the display area (8, 0) (16, 9) and creates a display image. The mask image created in the mask area (8, 0) (16, 9) can conceal the shared material arranged in the display image.

  The type “chat” and the name “u” are associated with “prohibited” as permission information corresponding to the user ID “14” and “non-participant”. Accordingly, a mask image arranged in the (0, 5) (8, 9) area associated with the “non-participant” in the display area (mask area) is created. Next, the CPU 21 acquires the chat media having the name “u” from the HDD 24. The CPU 21 arranges the chat image with the name “u” in the display area (0, 5) (8, 9) in addition to the captured image and the shared material, and creates a display image. The mask image created in the mask areas (0, 5) (8, 9) can hide the chat image arranged in the display image. The minutes image is generated as described above.

  As illustrated in FIG. 12, when the CPU 21 determines that the medium stored in the first table 241 has not been added or changed (S105: NO), any of the display areas stored in the first table 241 is displayed. It is determined whether or not has been changed (S112). When the position change data is received in the main process (S71), since the display area after the change is stored in the first table 241 (S73), it is determined that the display area has been changed (S112: YES). . CPU21 advances a process to S107.

  When determining that the position change data has not been received in S112 (S112: NO), the CPU 21 determines whether the second table 242 (level table 2421 and authority table 2422) has been changed (S114). The second table 242 is changed to the case where the authority acquisition process is executed (S15) after receiving the connection request data from the conference device 15 in the main process (see FIG. 8) (S11). The second table 242 is changed to the case where authority change data is received from the conference apparatus 15 in the main process (see FIG. 10) (S61) (S63). If the CPU 21 determines that the second table 242 has been changed (S114: YES), the process proceeds to S107. If the CPU 21 determines that the second table 242 has not been changed (S114: NO), the process returns to S101.

  As described above, the server 11 stores the time information, name, permission / denial information, and display area (mask area) in the third table 243 in association with each other. The server 11 can create a mask image based on the third table 243. The mask image can hide the image included in the display image. Therefore, by superimposing the mask image on the created display image, it is possible to prohibit the user from browsing an image based on a specific medium. In this way, the server 11 can record information in the third table 243 so that the display image created during the remote conference can be viewed after the remote conference is finished in a manner according to the viewing authority of the user.

  Further, since the third table 243 includes time information and is created each time a medium is added or changed, the server 11 may permit or prohibit browsing of images based on the medium on a timely basis. it can. For this reason, the server 11 can permit browsing of images within a specific time, and prohibit browsing of images at other times.

  The server 11 can store necessary information in the third table 243 when a medium is added or changed. For this reason, the server 11 can reliably acquire the browsing authority of the added or changed media and store it in the third table 243. Further, the server 11 can reliably store all the media received from the conference device 15 in the third table 243.

  The server 11 can store necessary information in the third table 243 when the new conference device 15 participates in the remote conference. For this reason, the server 11 can reliably acquire the browsing authority for the conference apparatus 15 newly participating in the remote conference, and can store it in the third table 243. The server 11 can reliably store information on all the conference devices 15 participating in the remote conference in the third table 243.

  Further, even when the display area of the image is changed, the server 11 can display the mask image in the display area of the image after the change, so that the browsing of the image can be appropriately prevented.

  The server 11 can specify a mask area for each user ID and store the mask area in the third table 243. Therefore, even if the arrangement of the images is different for each conference device 15, the specific image can be reliably hidden by the mask image.

  Further, the server 11 can specify a plurality of mask areas for hiding a plurality of images even when a plurality of types of browsing are prohibited for a specific conference device 15. Therefore, the CPU 21 can prohibit the user from browsing a plurality of images that are prohibited from browsing.

  In addition, this invention is not limited to the said embodiment, A various change is possible. In the above embodiment, when a medium is added or changed in the first table 241 (S105: YES), the viewing authority is acquired by transmitting the authority request data to the conference device 15. When the media is added to the first table 241 or when the media is changed, the CPU 21 does not transmit the authority request data, and acquires the browsing authority by reading the information stored in the second table 242. Good. In the above embodiment, when it is determined that the connection request data has been received (S11: YES), the viewing authority is acquired by transmitting the authority request data to the conference device 15. When the CPU 21 determines that the connection request data has been received, the CPU 21 does not have to transmit the authority request data. For example, when it is determined that the recording start data has been received (S53: YES), the CPU 21 may transmit authority request data. Further, the CPU 21 may specify the viewing authority according to the form of the remote conference (presentation format, lecture format, free discussion, etc.) indicated by the conference ID.

  In the above embodiment, the third table 243 is stored in the HDD 24 by the CPU 21 of the server 11 executing the process based on the recording program. For example, the third table 243 may be stored on the basis of the media received by the server 11 by the CPU of the recording device (another server or the like) connected to the server 11 executing the recording program.

  In the above embodiment, a display image is created by the server 11 and transmitted to the conference device 15. The server 11 may transfer the media received from the conference device 15 to another conference device 15 without creating a display image. The CPU of the conference device 15 that has received media from the conference device 15 may create a display image based on the received media. In this case, the CPU of the conference apparatus 15 may store the third table 243 based on the media received from the server 11 by the conference apparatus 15 by executing the recording program. Alternatively, the third table 243 may be stored based on the media received by the conference apparatus 15 from the server 11 by the CPU of the recording apparatus connected to the conference apparatus 15 executing the recording program.

  In the above embodiment, every time the third table 243 is created, a mask image creation process and a minutes image generation process are executed (S111, S113). On the other hand, a mask image creation process and minutes data generation process may be performed at the end of the recording process (S101: NO).
