Video communication device 10 is a device that can be used, for example, in a web conference, allowing participants in the web conference to communicate using video and audio.

The camera 12 captures images of the periphery of the video communication device 10. The camera 12 is positioned so as to capture images in the direction in which the display unit 20 is facing, for example. The camera 12 captures continuous images in time series, so-called moving images, at a predetermined frame rate. The camera 12 outputs the captured images to the image acquisition unit 30. The camera 12 may be an external camera connected to the video communication device 10.

The microphone 14 picks up sounds around the video communication device 10. The microphone 14 picks up the sound of a person speaking into the microphone 14. The microphone 14 outputs the picked up sound to the sound acquisition unit 32. The microphone 14 may be an external microphone connected to the video communication device 10.

The operation reception unit 16 receives various operations on the video communication device 10 through user operations. The operation reception unit 16 receives, for example, an operation from a user to restrict the transmission of video to other video communication devices. The operation reception unit 16 may include, for example, a touch panel, a switch, a button, etc. The operation reception unit 16 outputs operation information related to the operation received from the user, etc. to the operation control unit 34.

The communication unit 18 is connected to a communication network such as the Internet (not shown) by wire or wirelessly. The communication unit 18 transmits and receives information to and from other external devices via the communication network. The communication unit 18 transmits and receives information to and from, for example, other video communication devices. The communication unit 18 transmits, for example, video captured by the camera 12 and audio picked up by the microphone 14 to the other video communication device. The communication unit 18 receives, for example, video captured by the camera of the other video communication device and audio picked up by the microphone. The communication unit 18 receives, for example, information from the other video communication device that restricts the video captured by the camera of the other video communication device. In the following description, when it is described that the communication unit 18 transmits video, etc. to the other video communication device, this also includes the communication unit 18 transmitting video, etc. to an external server to which the other video communication device is connected and from which the other video communication device can refer to the video, etc. transmitted by the communication unit 18. In addition, when it is described that the communication unit 18 receives video, etc. from another video communication device, this also includes the communication unit 18 receiving video, etc. from an external server, etc. to which the other video communication device is connected and which can refer to video, etc. transmitted by the other video communication device.

The display unit 20 displays various information. For example, the display unit 20 displays video of the user captured by the camera 12, video of other users captured by other video communication devices 10 participating in the WEB conference, etc. The display unit 20 displays, for example, a predetermined icon indicating the user of the video communication device 10, or an icon indicating the user of the other video communication devices participating in the WEB conference. The display unit 20 is, for example, a display including a liquid crystal display (LCD) or an organic EL (Electro-Luminescence) display.

The audio output unit 22 is a speaker, a headphone, or the like, which is provided in the video communication device 10, or an external speaker, a headphone, or the like connected to the video communication device 10. The audio output unit 22 outputs various types of audio. For example, the audio output unit 22 outputs audio uttered by other users transmitted from other video communication devices participating in the WEB conference.

The control unit 24 is a so-called video communication control device that controls the operation of each part of the video communication device 10. The control unit 24 realizes various functions by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing a program stored in a storage unit (not shown) using a RAM or the like as a working area. Therefore, the control unit 24 executes the video display method according to the embodiment. The control unit 24 is also a computer that runs the program according to the present invention. The control unit 24 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 24 may be realized by a combination of hardware and software.

The control unit 24 includes a video acquisition unit 30, an audio acquisition unit 32, an operation control unit 34, a communication control unit 36, a display control unit 38, an audio output control unit 40, an analysis unit 42, and an icon generation unit 44. In other words, the control unit 24 realizes the functions of the video acquisition unit 30, the audio acquisition unit 32, the operation control unit 34, the communication control unit 36, the display control unit 38, the audio output control unit 40, the analysis unit 42, and the icon generation unit 44.

The video acquisition unit 30 acquires the video output by the camera 12. For example, the video acquisition unit 30 acquires video captured by the camera 12 of an area including the face of the user of the video communication device 10.

The voice acquisition unit 32 acquires the voice output by the microphone 14. The voice acquisition unit 32 acquires, for example, the voice spoken by the user of the video communication device 10, acquired by the microphone 14.

The operation control unit 34 acquires operation information related to the operation accepted by the operation acceptance unit 16. For example, the operation control unit 34 accepts operation information related to an operation to restrict the transmission of video, which is accepted by the operation acceptance unit 16 from a user or the like.

The communication control unit 36 controls the communication unit 18. The communication control unit 36 controls the communication unit 18 to transmit and receive various information to and from other external devices. The communication control unit 36 controls, for example, the communication unit 18 to transmit and receive video and audio to and from other video communication devices.

The display control unit 38 causes various images to be displayed on the display unit 20. For example, the display control unit 38 causes images of the user of the video communication device 10 and users of other video communication devices participating in the WEB conference to be displayed. For example, when the communication unit 18 receives information restricting image display, the display control unit 38 causes the display unit 20 to display icons generated by the icon generation unit 44 instead of images of other users.

The audio output control unit 40 causes the audio output unit 22 to output various sounds. For example, the audio output control unit 40 causes the audio output unit 22 to output the sounds of other users participating in the web conference.

The analysis unit 42 analyzes the video acquired by the video acquisition unit 30 from the camera 12. The analysis unit 42 analyzes the audio acquired by the audio acquisition unit 32 from the microphone 14. The analysis unit 42, for example, recognizes a person from the video captured by the camera 12. For example, when the analysis unit 42 recognizes a person from the video captured by the camera 12, it analyzes at least one of the recognized actions and facial expressions.

The icon generation unit 44 generates various icons. For example, the icon generation unit 44 generates an icon according to the analysis results of the analysis unit 42.

[Display image]
A display image according to the first embodiment will be described with reference to Fig. 2. Fig. 2 is a diagram for explaining an example of a display image according to the first embodiment.

As shown in FIG. 2, the display image 20a displayed on the display unit 20 of the video communication device 10 includes a first display area 50, a second display area 52, a third display area 54, and a fourth display area 56. The display image 20a is an example of a screen that is displayed when, for example, four people including user U1 of the video communication device 10 are holding a web conference. An image similar to the display image 20a is also displayed on the video communication devices of the other three users other than the user of the video communication device 10.

The first display area 50 displays, for example, information about user U1, who is the first user of the four users. The second display area 52 displays, for example, information about the second user of the four users. The third display area 54 displays, for example, information about the third user of the four users. The fourth display area 56 displays, for example, information about the fourth user of the four users.

Video communication device 10 has a "video on mode" in which the video captured by camera 12 is transmitted to other video communication devices for display. Video communication device 10 has a "video off mode" in which camera 12 does not capture video and does not transmit video to other video communication devices. Video communication device 10 has a "video restricted mode" in which the video captured by camera 12 is transmitted to other video communication devices but the video is not displayed on the other video communication devices. In this embodiment, each user participating in the WEB conference can set the "video on mode", "video off mode", and "video restricted mode" as desired.

In the example shown in FIG. 2, user U1 selects the "video on mode," and the second user, third user, and fourth user each select the "video off mode."

In the first display area 50, an image of user U1 and an icon I1 are displayed. User U1 is displayed, for example, in the center of the first display area 50. Icon I1 is displayed in the upper right corner of the first display area 50. Icon I1 is an icon that shows information about user U1. Icon I1 may display, for example, the initials of user U1's name, such as "YS."

An icon I2 is displayed in the center of the second display area 52. Icon I2 is an icon that indicates information about the second user. Icon I2 may display the initials of the second user's name, such as "RS."

An icon I3 is displayed in the center of the third display area 54. Icon I3 is an icon that indicates information about the third user. Icon I3 may display the initials of the third user's name, such as "KT."

An icon I4 is displayed in the center of the fourth display area 56. Icon I4 is an icon that indicates information about the fourth user. Icon I4 may display the initials of the fourth user's name, such as "CJ."

When the "video restriction mode" is set, the video communication device 10 according to this embodiment transmits an icon with a changed display form according to the actions or facial expression of the user of the video communication device 10 to the other video communication devices participating in the WEB conference. By transmitting an icon with a changed display form, the video communication device 10 according to this embodiment allows other participants to properly understand the reaction of the user of the video communication device 10 even when the camera image is not displayed, thereby facilitating communication.

[Video Communication Device Processing]
The process of the video communication device according to the first embodiment will be described with reference to Fig. 3. Fig. 3 is a flow chart showing an example of the flow of the process of the video communication device according to the first embodiment.

The process in FIG. 3 is started, for example, when a WEB conference is started. When the process in FIG. 3 is started and communication with other participants in the WEB conference is started by the communication unit 18, the control unit 24 determines whether the camera 12 of the video communication device 10 is on or not (step S10). Specifically, when the video acquisition unit 30 is able to acquire video from the camera 12, it determines that the camera 12 is on. When it is determined that the camera 12 is on (step S10; Yes), the process proceeds to step S12. When it is not determined that the camera 12 is on (step S10; No), the process proceeds to step S16.

If step S10 is determined as Yes, the control unit 24 determines whether or not there is a transmission restriction on the acquired video (step S12). The acquired video has a transmission restriction when the video communication device 10 is set to a "video restriction mode." Specifically, the operation control unit 34 determines whether or not there is a restriction on transmitting the acquired video to another video communication device based on whether or not information regarding an operation to restrict video transmission has been received from the operation reception unit 16. If it is determined that there is no transmission restriction on the acquired video (step S12; No), the process proceeds to step S14. If it is determined that there is a transmission restriction on the acquired video (step S12; Yes), the process proceeds to step S18.

If the result of the determination in step S12 is No, the control unit 24 transmits the acquired video (step S14). Specifically, the communication control unit 36 transmits the video captured by the camera 12 to the other video communication device via the communication unit 18. FIG. 4 is a diagram for explaining the video transmitted by the communication control unit 36 to the other video communication device. In the process of FIG. 3, an example of transmitting a video or icon of the second user is described, but the same applies to the user U1, the third user, and the fourth user. In the example shown in FIG. 4, the communication control unit 36 transmits to the other video communication device a video showing the second user U2 as a video captured by the camera 12 of the video communication device 10 used by the second user, and an icon I2 indicating the second user or information that can generate the icon I2 in the other video communication device. Then, proceed to step 26.

If step S10 is determined as No, the control unit 24 transmits a normal icon (step S16). If step S10 is determined as No, then the video communication device 10 is set to "video off mode." Specifically, the communication control unit 36 transmits a normal icon to be displayed on the other video communication device via the communication unit 18. FIG. 5 is a diagram for explaining the normal icon that the communication control unit 36 transmits to the other video communication device. For example, if the video acquisition unit 30 is unable to acquire video from the camera 12, the communication control unit 36 transmits an icon I2 corresponding to the second user to the other video communication device. Then, proceed to step S26.

If step S12 is judged as Yes, the control unit 24 judges whether or not a person has been detected from the video acquired from the camera 12 (step S18). Specifically, the analysis unit 42 performs person recognition processing on the video acquired from the camera 12, for example, using dictionary data for recognizing people (not shown), to judge whether or not a person is included in the video. If it is judged that a person has been detected (step S18; Yes), the process proceeds to step S20. If it is not judged that a person has been detected (step S18; No), the process proceeds to step S16.

If the answer to step S18 is Yes, the control unit 24 determines whether or not a movement or facial expression of the detected person has been detected (step S20). Specifically, the analysis unit 42 detects at least one of the movement and facial expression of the detected person by using a well-known motion detection process, such as an AI function using dictionary data for recognizing facial expressions (not shown), for example. If it is determined that a movement or facial expression of the person has been detected (step S20; Yes), the process proceeds to step S22. If it is not determined that a movement or facial expression of the person has been detected (step S20; No), the process proceeds to step S16.

The movement or facial expression of the person detected in step S20 can be said to be detection of a change in the person's movement or facial expression. For example, cases where the facial expression of the detected person changes to a smile, a nodding movement, a movement such as shaking the head from side to side, etc. are detected.

If the answer to step S20 is Yes, the control unit 24 generates an icon based on the analysis results (step S22). Specifically, the icon generation unit 44 generates an icon according to the analysis results of the actions or display of the person detected by the analysis unit 42. An icon according to the analysis results is, for example, an icon that is deformed to represent the actions or facial expressions of the person detected by the analysis unit 42, as compared to a normal icon such as that shown in FIG. 5. An icon according to the analysis results has at least one of its shape, configuration, and movement changed to represent the analysis results.

The icons generated by the icon generating unit 44 according to the first embodiment will be described with reference to Figures 6, 7, 8, and 9. Figures 6 to 9 are diagrams for explaining an example of an icon generated by the icon generating unit 44 according to the first embodiment.

As shown in FIG. 6, for example, when the analysis unit 42 detects a nodding motion of the second user, the icon generation unit 44 generates an icon I2A by tilting the icon I2 shown in FIG. 5 as if nodding. As shown in FIG. 7, for example, when the analysis unit 42 detects a motion of the second user turning to the right, the icon generation unit 44 generates an icon I2B by tilting the icon I2 shown in FIG. 5 to turn to the right. As shown in FIG. 8, for example, when the analysis unit 42 detects a motion of the second user turning to the left, the icon generation unit 44 generates an icon I2C by tilting the icon I2 shown in FIG. 5 to turn to the left. That is, the icon generation unit 44 generates an icon according to the analysis result of the second user's motion by the analysis unit 42.

As shown in FIG. 9, for example, when the analysis unit 42 detects a smile of the second user, the icon generation unit 44 generates an icon I2D indicating a smile. That is, the icon generation unit 44 can generate an icon according to the analysis result of the second user's facial expression by the analysis unit 42.

Returning to FIG. 3, the control unit 24 transmits the generated icon (step S24). Specifically, the communication control unit 36 transmits, for example, an icon such as those shown in FIG. 5 to FIG. 9 to another video communication device.

The method by which the communication control unit 36 according to the first embodiment transmits an icon will be described with reference to Figs. 10 and 11. Figs. 10 and 11 are diagrams for explaining the method by which the communication control unit 36 according to the first embodiment transmits an icon.

FIG. 10 is a diagram for explaining a method of transmitting an icon reflecting a nodding motion. In this case, first, the communication control unit 36 transmits, for example, a normal second user icon I2 to the other video communication device (step S1). Next, the communication control unit 36 transmits, for example, an icon I2A indicating that the second user is nodding to the other video communication device (step S2). The communication control unit 36 transmits, for example, an icon in the state of step S1 and an icon in the state of step S2 every second, thereby giving the icon a nodding motion and reflecting the nodding motion of the second user. In other words, when the second user is performing a nodding motion, the communication control unit 36 transmits the icon of the second user performing the nodding motion as an icon that performs the motion shown in FIG. 10.

FIG. 11 is a diagram for explaining a method of transmitting an icon reflecting a motion of shaking one's head from side to side. First, the communication control unit 36 transmits, for example, an icon I2B indicating that the second user is facing right to the other video communication device (step S3). Next, the communication control unit 36 transmits, for example, an icon I2C indicating that the second user is facing left to the other video communication device (step S4). The communication control unit 36 transmits, for example, an icon of the state of step S3 and the state of step S4 every second, thereby giving the icon a motion of shaking one's head from side to side, thereby reflecting the motion of the second user shaking his or her head from side to side. In other words, when the second user is shaking his or her head from side to side, the communication control unit 36 transmits the icon of the second user shaking his or her head from side to side as an icon that performs the motion shown in FIG. 11.

In addition, when the communication control unit 36 displays the second user's smiling face in an icon, the communication control unit 36 reflects the second user's smiling face by continuously transmitting the icon I2D shown in FIG. 9 to other video communication devices while the smiling face is being detected.

Returning to FIG. 3, the control unit 24 transmits the generated icon to the other video communication device, and then proceeds to step S26.

After step S14, step S16, or step S24, the control unit 24 determines whether or not to end the process of FIG. 3 (step S26). For example, when the operation reception unit 16 receives an operation to end the process of FIG. 3 and an operation to turn off the power, the control unit 24 determines that the process of FIG. 3 is to be ended. If it is determined that the process is to be ended (step S26; Yes), the control unit 24 ends the process of FIG. 3. If it is not determined that the process is to be ended (step S26; No), the control unit 24 proceeds to step S10. The end of the process determined in step S26 is, for example, the end of the WEB conference. Also, even if the WEB conference is not ended, if the user of the video communication device 10 ends the connection to the WEB conference, the control unit 24 ends the process of FIG. 3.

As described above, in the first embodiment, when video display is restricted in a web conference or the like, the icon of the user whose video display is restricted reflects the user's actions or facial expressions and is transmitted to other video communication devices. In this way, in the first embodiment, even when the user of the video communication device 10 is not displaying camera video, other participants can properly understand the reaction of the user of the video communication device 10, making communication smoother.

[Second embodiment]
The configuration of the video communication device according to the second embodiment will be described with reference to Fig. 12. Fig. 12 is a diagram for explaining the configuration of the video communication device according to the second embodiment.

As shown in FIG. 12, the video communication device 10A according to the second embodiment differs from the video communication device 10 shown in FIG. 1 in that the control unit 24A includes a determination unit 46.

The judgment unit 46 judges the emotions of the user of the video communication device 10A. The judgment unit 46 judges whether the movement or facial expression of the user of the video communication device 10A included in the analysis result of the analysis unit 42 is a positive movement or facial expression. A positive movement or facial expression may mean, for example, a positive reaction to a certain statement. Specifically, the judgment unit 46 judges that the movement or facial expression is positive when the analysis unit 42 detects that the user of the video communication device 10A has nodded or smiled. The judgment unit 46 may judge whether the movement or facial expression of the user of the video communication device 10A is positive based on the analysis result of the audio by the analysis unit 42 in addition to the analysis result of the video by the analysis unit 42.

When the user's movement or facial expression is positive, the video communication device 10A generates an icon that reflects that movement or facial expression and transmits the icon to another video communication device.

The processing of the video communication device according to the second embodiment will be described with reference to FIG. 13. FIG. 13 is a flowchart showing an example of the processing flow of the video communication device according to the second embodiment.

The processes from steps S30 to S40 and from steps S44 to S48 are the same as the processes from steps S10 to S20 and from steps S22 to S26, respectively, and therefore will not be described here.

If the answer to step S40 is Yes, the control unit 24 determines whether the detected movement or expression is a positive movement or expression (step S42). Specifically, the judgment unit 46 determines whether the movement or expression is a positive movement or expression based on whether the detected movement or expression matches a predetermined positive movement or expression. If it is determined to be a positive movement or expression (step S42; Yes), the process proceeds to step S44. If it is not determined to be a positive movement or expression (step S42; No), the process proceeds to step S36.

As described above, in the second embodiment, when video display is restricted in a web conference or the like, if the user of video communication device 10A has a positive movement or facial expression, the icon of the user of video communication device 10A is transmitted to the video communication devices of the other users participating in the web conference with the user's movement or facial expression reflected in the icon. In this way, in the second embodiment, even when the user of video communication device 10A does not display camera video, the other participants can properly understand the positive reaction of user A of video communication device 10, facilitating communication.

In addition, when there are many participants in a web conference and many images of the faces of other users participating in the web conference are displayed on the display screen of the display unit 20, it is difficult for the speaker to grasp the overall reactions of the other users. In such cases, in each of the above-mentioned embodiments, the reactions or positive reactions of other users are displayed as simple icons rather than images, so that the speaker can properly grasp the overall reactions.

Although the embodiments of the present invention have been described above, the present invention is not limited to the contents of these embodiments. The above-mentioned components include those that a person skilled in the art can easily imagine, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the above-mentioned components can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the components can be made without departing from the spirit of the above-mentioned embodiments.
