<Processing or operation>
Subsequently, the processing or operation of the present embodiment will be described. In the present embodiment, in a conference held in a room, a presenter who is an example of a user who operates a personal terminal 2a performs streaming transmission to a shared screen ss, and a participant who is an example of a user who operates a personal terminal 2c. An example of attending a meeting will be described.

FIG. 11 is a sequence diagram of an example of a process of performing a screen capture of the shared screen ss on the personal terminal 2c. It is assumed that the personal terminal 2a and the personal terminal 2c access the same room and display the personal board screen 1000 in the same room before the processing of the sequence diagram of FIG. 11 is started. When the personal terminal 2c displays the personal board screen 1000, it inquires about the prohibition / permission of screen capture of the room, and based on the inquiry result, whether the screen capture by the participants is prohibited or permitted. May be determined.

In step S10, the presenter who operates the personal terminal 2a selects a target to be screen-transmitted to the shared screen ss. The personal terminal 2a specifies the room ID and transmits the streaming of the target to be screen-transmitted to the shared screen ss of the specific room by WebRTC. WebRTC is a standard that realizes high-speed data communication via a web browser, and is one of HTML APIs. WebRTC can send and receive large-capacity data such as video and audio in real time.

Proceeding to step S12, the content management server 6 performs streaming distribution by WebRTC to the personal board screen 1000 of the personal terminal 2c associated with the room ID specified in step S10. The personal terminal 2c displays the streamed projection screen 1040 in the projection area of the personal board screen 1000 displayed by the web browser, for example, as shown in FIG. 7.

In step S14, the participant who operates the personal terminal 2c performs an operation of pressing the capture button 1016. The personal terminal 2c makes a capture shooting request to the image processing unit 23c or the image processing unit 63 of the content management server 6. Here, it is assumed that the personal terminal 2c makes a capture shooting request to the image processing unit 63 of the content management server 6.

In steps S16 to S18, the image processing unit 63 of the content management server 6 captures the capture of the projection screen 1040 at that time, and returns the image file of the captured image 1022 to the personal terminal 2c.

In the sequence diagram of FIG. 11, the content management server 6 captures the projection screen 1040, but the personal terminal 2c may capture the projection screen 1040. For example, when a capture of the projection screen 1040 is taken by the personal terminal 2c, the image file of the captured image 1022 is transmitted from the personal terminal 2c to the content management server 6. The content management server 6 transmits the returned image file of the captured image 1022 to the personal terminal 2c.

In step S20, the personal terminal 2c that has received the image file of the captured image 1022 additionally displays the captured image 1022 of the projection screen 1040 in the memo area as shown in FIG. 8, for example. Further, the personal terminal 2c displays the text memo area 1024 attached to the captured image 1022 on the same sheet 1020 as the additionally displayed captured image 1022, as shown in FIG. 8, for example.

FIG. 12 is a sequence diagram of an example of a process in which the presenter prohibits screen capture from the personal terminal 2a. As in FIG. 11, the personal terminal 2a and the personal terminal 2c access the same room and display the personal board screen 1000 in the same room before the processing of the sequence diagram of FIG. 12 is started. And.

Steps S30 to S32 are the same as steps S10 to S12 of FIG. In step S34, the presenter who operates the personal terminal 2a presses the capture prohibition button 1034. The operation of pressing the capture prohibition button 1034 is an example of an operation in which the presenter manually and explicitly prohibits screen capture.

FIG. 13 is a diagram for explaining an example of the capture prohibition button. FIG. 13A shows an example of the capture prohibition button 1034 before the screen capture is prohibited. FIG. 13B shows an example of the capture prohibition button 1034 after the screen capture is prohibited. As shown in FIG. 13, the display contents may be different between the capture prohibition button 1034 before the screen capture prohibition and the capture prohibition button 1034 after the screen capture prohibition.

The personal terminal 2a that receives the operation of pressing the capture prohibition button 1034 before the screen capture prohibition (screen capture permitted state) in FIG. 13 (A) is received from the presenter can make a capture prohibition request and prohibit the screen capture. The personal terminal 2a that received the operation of pressing the capture prohibition button 1034 after the screen capture prohibition of FIG. 13B (screen capture prohibition state) is received from the presenter makes a capture prohibition release request and cancels the screen capture prohibition. it can.

Instead of the capture prohibition button 1034 in FIG. 13, a toggle button as shown in FIG. 14 (A) or a radio button as shown in FIG. 14 (B) may be used. FIG. 14 is an image diagram of an example of a capture prohibition button realized by a toggle button or a radio button.

Further, as shown in FIG. 15, the personal terminal 2a that has received the operation prohibiting screen capture from the presenter displays a screen for inventor to set the time for prohibiting screen capture (capture prohibition time), and the capture prohibition time. You may accept the setting of. In this case, the screen capture prohibition is released after the set capture prohibition time elapses.

FIG. 15 is an image diagram of an example of a screen for setting the capture prohibition time. The capture prohibition time set in FIG. 15 can be used, for example, when it is not possible to determine the page switching of the projection screen 1040. The capture prohibition time set in FIG. 15 may be used, for example, when it is possible to determine the page switching of the projection screen 1040.

The personal terminal 2a that has received the operation of pressing the capture prohibition button 1034 before the screen capture is prohibited in step S34 makes a capture prohibition request to the image processing unit 63 of the content management server 6. The image processing unit 63 notifies the participant's personal terminal 2c of the capture availability information prohibiting screen capture.

In step S38, the personal terminal 2c updates the UI to the personal board screen 1000 for which screen capture is prohibited, as shown in FIG. 16, for example. FIG. 16 is an image diagram of an example of the personal board screen 1000 for which screen capture is prohibited. FIG. 16A is an image diagram of the personal board screen 1000 for which screen capture is prohibited. Further, FIG. 16B is an image diagram of a capture button displayed on the personal board screen 1000 in which screen capture is prohibited. As shown in FIG. 16, the capture button 1016 displayed on the personal board screen 1000 for which screen capture is prohibited is limited to the form shown in FIG. 16 (B) as long as it is a button for the participants to recognize that screen capture is not possible. It does not matter in any form.

Further, the personal board screen 1000 for which screen capture is prohibited is not limited to FIG. 16, and may be, for example, the personal board screen 1000 as shown in FIG. FIG. 17 is an image diagram of an example of the personal board screen 1000 for which screen capture is prohibited. In the personal board screen 1000 of FIG. 17, when the capture button 1016 displayed on the personal board screen 1000 whose screen capture is prohibited is pressed by the participant, the participant is informed that the capture is prohibited by displaying a dialog. Present.

The personal terminal 2a that has received the operation of pressing the capture prohibition button 1034 after the screen capture is prohibited in step S40 requests the image processing unit 63 of the content management server 6 to release the capture prohibition. The image processing unit 63 notifies the participant's personal terminal 2c of the capture availability information of the screen capture permission.

In step S44, the personal terminal 2c updates the personal board screen 1000 for which screen capture is prohibited, as shown in FIG. 16, to the UI of the personal board screen 1000 for which screen capture is permitted.

In the above, the process of capturing the capture of the projection screen 1040 during which the screen capture is prohibited is prohibited. However, for example, by performing the mask process on the projection screen 1040 as shown in FIGS. 18 to 19, the projection before the mask process is performed. The capture of screen 1040 may not be captured.

FIG. 18 is a diagram illustrating an example of performing mask processing on the projection screen 1040 for which screen capture is prohibited. FIG. 18A is an example of the personal board screen 1000 of the participant's personal terminal 2c while the screen capture is prohibited. The projection screen 1040 is masked, and the projection screen 1040 before the masking is not displayed.

FIG. 18B is a screen example of the shared terminal 4 described later while screen capture is prohibited. On the shared terminal 4, the projection screen 1040 before the mask processing is displayed even when screen capture is prohibited. As a result, the participants cannot view the projection screen 1040 before the mask processing on their personal terminal 2c, but can view the projection screen 1040 before the mask processing on the shared terminal 4.

Even if the participant makes a capture shooting request on the personal board screen 1000 of FIG. 18A, the captured image 1022 of the projection screen 1040 after the mask processing is captured as shown in FIG. FIG. 19 is an image diagram for explaining the captured image of the projection screen 1040 after the mask processing.

Further, in the personal board screen 1000 of FIG. 18A, even if a function (screenshot function) for capturing a screen image of an OS such as Windows (registered trademark) is used, the projection screen 1040 before mask processing cannot be captured. Therefore, it is highly confidential. The mask processing may be a black screen, a white screen, a mosaic processing, replacement of another screen, or the like.

Further, when a participant makes a capture shooting request on the personal board screen 1000 without masking the projection screen 1040, the captured image 1022 of the projection screen 1040 after the mask processing shown in FIG. 19 is captured. It may be processed as follows.

<Summary>
According to the present embodiment, a presenter or the like who is a provider of the projection screen 1040 can easily specify prohibition / permission of screen capture of the projection screen 1040 displayed in the projection area of the personal board screen 1000. it can. Therefore, even if the presenter or the like does not want to capture the screen, the screen capture can be prohibited and the screen can be projected on the projection area.
