Description

CONTROL APPARATUS, CONTROL METHOD, TRANSMISSION TERMINAL, TRANSMISSION METHOD, RECEPTION TERMINAL, RECEPTION METHOD, AND CONTROL SYSTEM

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Japanese Priority Patent Application JP 2013-160132 filed August 1, 2013, the entire contents of which are incorporated herein by reference.

The present disclosure relates to a control apparatus, a control method, a transmission terminal, a transmission method, a reception terminal, a reception method, and a control system.

In recent years, there has been an increase in the chance that a user will sees images at various locations such as a station or a store. The types of images which the user sees are sometimes images displayed by a display device such as digital signage, and are sometimes images which are printed on paper for advertising. In the case where the user discovers an image of interest at some location, there will be cases which can be considered in which the user stores data related to this image in a portable terminal of the user himself or herself, and wants to browse the data displayed by this terminal.

For example, in the case where a two-dimensional bar code is attached to an image, when the user moves the terminal so as to fit the two-dimensional bar code within an imaging range, and takes a photograph, it is possible for the terminal to recognize the two-dimensional bar code from the captured image and to receive data corresponding to the two-dimensional bar code. Various technologies have been disclosed as technologies related to the recognition of a two-dimensional bar code (for example, refer to PTL 1).

<<0. General Technology>>
First, general technology will be described prior to description of embodiments of the present disclosure. FIG. 1 is a figure for describing a functional outline of a general control system 90. As shown in FIG. 1, the control system 90 includes a transmission terminal 700 and a reception terminal 800. Applications are executed in the transmission terminal 700, and a video image Im1 is displayed as an execution result of the application. Here, it will be assumed that a case is considered in which a user wants to display the video image Im1 on the reception terminal 800 at the time when viewing the video image Im1.

In such a case, when the user brings the reception terminal 800 close to the transmission terminal 700, a connection process between the transmission terminal 700 and the reception terminal 800 starts. When the connection process between the transmission terminal 700 and the reception terminal 800 is completed, a window D93, which indicates that the video image Im1 will be displayed on the transmission terminal 700, is displayed on the reception terminal 800. Afterwards, the video image Im1 is transmitted from the transmission terminal 700 to the reception terminal 800, and the reception terminal 800 displays the video image Im1.

To continue, the general technology will be additionally described while referring to sequence diagrams. Note that, an example will be shown in which the control system 90 operates in accordance with Wi-Fi Direct (registered trademark), as an example, in the following sequence charts.

FIG. 2 is a sequence diagram which shows an operation example of the general control system 90. In particular, the example shown in FIG. 2 corresponds to an example in which the transmission terminal 700 selects a connection partner. First, each of the transmission terminal 700 and the reception terminal 800 transmit a detection signal for detecting a terminal in the surroundings (S901). In the case where the reception terminal 800 which receives this detection signal is present, the transmission terminal 700 displays a window D91 which inquires whether or not to transmit a connection request to this reception terminal 800 (S902).

When an operation is accepted from a user which indicates that a connection request is to be transmitted to the reception terminal 800 (S903), the transmission terminal 700 transmits a connection request to the reception terminal 800 (S904). When the connection request is received from the transmission terminal 700, the reception terminal 800 displays a window D92 which inquires whether or not to accept the connection request from the transmission terminal 700 (S905). When an operation is accepted from the user which indicates that the connection request is to be accepted (S906), the reception terminal 800 transmits a connection response to the transmission terminal 700 (S907), and the transmission terminal 700 transmits a confirmation message to the reception terminal 800 (S908).

To continue, when an authentication, WPS (registered trademark) and association are performed between the transmission terminal 700 and the reception terminal 800 (S909, S910 and S911), and an RTP (Real-time Transport Protocol) session is established in an RTSP (Real Time Streaming Protocol) (S912), the reception terminal 800 displays a window D93 which indicates that the video image Im1 of the transmission terminal 700 will be displayed (S913). Afterwards, the transmission terminal 700 transmits the video image Im1 to the reception terminal 800 by the RTP (S914), and when the video image Im1 is received from the transmission terminal 700, the reception terminal 800 displays the video image Im1 (S915).

FIG. 3 is a sequence diagram which shows an operation example of the general control system 90. In particular, the example shown in FIG. 3 corresponds to an example in which the reception terminal 800 selects a connection partner. First, each of the transmission terminal 700 and the reception terminal 800 transmit a detection signal for detecting a terminal in the surroundings (S901). In the case where the transmission terminal 700 which receives this detection signal is present, the reception terminal 800 displays a window D91 which inquires whether or not to transmit a connection request to this transmission terminal 700 (S902).

When an operation is accepted from a user which indicates that a connection request is to be transmitted to the transmission terminal 700 (S903), the reception terminal 800 transmits a connection request to the transmission terminal 700 (S904). When the connection request is received from the reception terminal 800, the transmission terminal 700 displays a window D92 which inquires whether or not to accept the connection request from the reception terminal 800 (S905). When an operation is accepted from the user which indicates that the connection request is to be accepted (S906), the transmission terminal 700 transmits a connection response to the reception terminal 800 (S907), and the reception terminal 800 transmits a confirmation message to the transmission terminal 700 (S908).

Heretofore, general technology has been described. In such general technology, since an operation is sought after from a user which indicates that a connection request is to be transmitted, there is the possibility that the operation will become complicated for the user. On the other hand, while the complexity of an operation provided to the user will be reduced if a connection request is transmitted without waiting for an operation from the user, there is the possibility that incorrect data transmission will be performed from the transmission terminal 700 to the reception terminal 800. In the present disclosure, technology is provided for reducing the possibility of incorrect data transmission being performed from the transmission terminal 700 to the reception terminal 800, while reducing the complexity of operations provided to the user.

In addition, in such general technology, a window D93 is displayed which indicates that a video image Im1 of the transmission terminal 700 will be displayed, and the video image Im1 is suddenly displayed subsequent to the window D93. A progress bar can also be displayed which shows the progress condition of the connection process while the connection process is being performed. However, it may be difficult for the user to intuitively understand what process is being executed, even if such a display is performed. In the present disclosure, technology is proposed in which the user intuitively and easily understands what process is being executed.

Further, a case will be assumed in which a two-dimensional bar code is attached to the video image Im1 displayed by the transmission terminal 700. In such a case, when the user moves the reception terminal 800 so as to fit the two-dimensional bar code within an imaging range, and takes a photograph, it is possible for the reception terminal 800 to recognize the two-dimensional bar code from the captured image and to receive the video image Im1 corresponding to the two-dimensional bar code. However, in the case where a two-dimensional bar code is recognized from a captured image, time may be necessary in order to recognize the two-dimensional bar code. Further, time may be necessary in order to specify data corresponding to the two-dimensional bar code. In the present disclosure, technology is proposed capable of reducing the time which may be necessary for storing desired data in the reception terminal 800.

<<1. The First Embodiment>>
First, a first embodiment of the present disclosure will be described. In the first embodiment of the present disclosure, a control apparatus 300, which controls data transmission from a transmission terminal 100 to a reception terminal 200, is incorporated into the reception terminal 200. However, the control apparatus 300 may not necessarily be incorporated into the reception terminal 200, such as will be described in the other embodiments.

<1-1. Functional outline of the control system>
First of all, a functional outline of a control system 10 according to the first embodiment of the present disclosure will be described. FIG. 4 is a figure for describing a functional outline of the control system 10 according to the first embodiment of the present disclosure. As shown in FIG. 4, the control system 10 includes a transmission terminal 100 and a reception terminal 200. An application is executed in the transmission terminal 100, and a video image Im1 is displayed as an execution result of the application. Here, it will be assumed that a case is considered in which a user wants to display the video image Im1 on the reception terminal 200 at the time when viewing the video image Im1.

In such a case, when the user moves the reception terminal 200 so that a part or all of the video image Im1 fits within an imaging range of the reception terminal 200, a captured video image Im0 is displayed by the reception terminal 200. Here, for example, in the case where a feature amount of an image displayed by the transmission terminal 100, and a feature amount of an image captured by the reception terminal 200, are similar or match each other, a connection process between the transmission terminal 100 and the reception terminal 200 may be started. Further, when the connection process between the transmission terminal 100 and the reception terminal 200 is completed, the transmission terminal 100 may transmit the video image Im1 to the reception terminal 200, and the reception terminal 200 may display the video image Im1.

The feature amounts extracted from the images are not particularly limited, and for example, may be histograms representing a distribution of colors of the images, or may be histograms representing a distribution of luminance. Further, the feature amounts extracted from the images may be object regions recognized from the images, or may be face regions recognized from the images.

Note that, as an example, the present embodiment will described a case in which the transmission terminal 100 and the reception terminal 200 are connected via a wireless LAN (Local Area Network), for example, and communication is capable of being performed between the transmission terminal 100 and the reception terminal 200 via the wireless LAN. However, communication between the transmission terminal 100 and the reception terminal 200 may be by wireless communication not via the wireless LAN (for example, infrared communication or the like), or may be by wired communication.

Further, while a case is shown in FIG. 4 in which the transmission terminal 100 is a television apparatus and the reception terminal 200 is a tablet terminal, the type of terminal for each of the transmission terminal 100 and the reception terminal 200 is not particularly limited. For example, the type of terminal for each of the transmission terminal 100 and the reception terminal 200 may be a video camera, may be a smart phone, or may be a PDA (Personal Digital Assistant). Or, the type of terminal for each of the transmission terminal 100 and the reception terminal 200 may be a PC (Personal Computer), may be a mobile phone, may be a portable music playback apparatus, may be a mobile video processing apparatus, or may be a portable game machine.

Heretofore, a functional outline of the control system 10 according to the first embodiment of the present disclosure has been described.

<1-2. Functional configuration example of the transmission terminal>
To continue, a functional configuration example of the transmission terminal 100 according to the first embodiment of the present disclosure will be described. FIG. 5 is a figure which shows a functional configuration example of the transmission terminal 100 according to the first embodiment of the present disclosure. As shown in FIG. 5, the transmission terminal 100 includes a control section 110, an input section 120, an imaging section 130, a detection section 140, a storage section 150, a communication section 160, and a display section 170.

For example, the control section 110 corresponds to a processor such as a CPU (Central Processing Unit). The control section 110 exhibits the various functions of the control section 110, by executing programs stored in the storage section 150 or another storage medium. The control section 110 has a display control section 111, a captured image acquisition section 112, and a communication control section 113. Each of these functional sections of the control section 110 will be described afterwards.

The input section 120 has a function which accepts an operation from a user. The input section 120 outputs the operation accepted from the user to the control section 110. The operation can be used for the execution of a program. Further, for example, the input section 120 can accept an operation from the user which starts the activation of a program. Further, for example, the input section 120 can accept an operation from the user which completes the execution of a program. While the input section 120 is incorporated into the transmission terminal 100 in the example shown in FIG. 5, the input section 120 may be present outside of the transmission terminal 100.

The imaging section 130 acquires a captured image by capturing an imaging range, and outputs the captured image to the control section 110. The imaging section 130 performs imaging by imaging magnification set in accordance with an operation input to the input section 120. While an adjustment of the imaging magnification can be implemented by a zoom function, this zoom function is not particularly limited, and may be an optical zoom function, or may be an electronic zoom function. Note that, while the imaging section 130 is integrated with the transmission terminal 100 in the example shown in FIG. 5, the imaging section 130 may be constituted separately from the transmission terminal 100.

The detection section 140 detects prescribed sensor data, and outputs the detected sensor data to the control section 110. The detection section 140 has a GPS (Global Positioning System) antenna, and detects GPS data (latitude and longitude of the present position of the transmission terminal 100) by using GPS signals received by the GPS antenna. Note that, the sensor data detected by the detection section 140 may be data other than GPS data. Further, while the detection section 140 is integrated with the transmission terminal 100 in the example shown in FIG. 5, the detection section 140 may be constituted separately from the transmission terminal 100.

The storage section 150 stores programs for operating the control section 110, by using a recording medium such as a semiconductor memory or a hard disk. Further, for example, the storage section 150 can store various types of data used by the programs (for example, various setting information, contents or the like). Note that, while the storage section 150 is integrated with the transmission terminal 100 in the example shown in FIG. 5, the storage section 150 may be constituted separately from the transmission terminal 100.

The communication section 160 is capable of communicating with the reception terminal 200. The form of the communication by the communication section 160 is not particularly limited, and the communication by the communication section 160 may be wireless communication, or may be wired communication. Note that, while the communication section 160 is integrated with the transmission terminal 100 in the example shown in FIG. 5, the communication section 160 may be constituted separately from the transmission terminal 100.

The display section 170 performs display of various types of information, in accordance with a control by the control section 110. For example, the display section 170 may include an LCD (Liquid Crystal Display), or an organic EL (Electroluminescence) display apparatus. Or, the display section 170 may include an audio output apparatus such as a speaker or headphones. Note that, while the display section 170 is integrated with the transmission terminal 100 in the example shown in FIG. 5, the display section 170 may be constituted separately from the transmission terminal 100.

In the case where it is judged that a comparison result shows matching or similarities between information of a display image displayed by one terminal out of the transmission terminal 100 and the reception terminal 200, and information of a captured image captured by the other terminal, the communication control section 113 causes the communication section 160 to perform data communication to the reception terminal 200. According to such a function of the communication control section 113, it becomes possible to reduce the possibility that incorrect data transmission is performed from the transmission terminal 100 to the reception terminal 200, while reducing the complexity of operations provided to a user. The data transmitted to the reception terminal 200 is not particularly limited, and may be at least a video image, or may be at least an application.

The information of a display image and the information of a captured image are each not particularly limited. For example, the information of a display image may include a feature amount extracted from the display image, and the information of a captured image may include a feature amount extracted from the captured image. In such a case, while time may be necessary in order to extract a feature amount from the image, there is the possibility that the transmission of a feature amount will be more appropriate from the viewpoint of security than the transmission of the image itself prior to the completion of the connection process between the transmission terminal 100 and the reception terminal 200.

However, the information of the display image may include a part or all of the display image, and the information of the captured image may include a part or all of the captured image. Hereinafter, while a description will be mainly made for the case where a feature amount of a display image is used as the information of the display image, and a feature amount of a captured image is used as the information of the captured image, the information of the display image is not limited to a feature amount of the display image, and the information of the captured image is not limited to a feature amount of the captured image.

In the case where a video image is transmitted from the transmission terminal 100 to the reception terminal 200, the transmitted video image may be any type of video image, and may include at least a video image Im1 displayed by the transmission terminal 100. In such a case, it becomes possible to store this video image Im1 itself in the reception terminal 200, at the time when a user becomes interested in the video image Im1 displayed by the transmission terminal 100.

Further, in the case where an application is transmitted from the transmission terminal 100 to the reception terminal 200, the transmitted application may be any type of application, and may include at least an application executed by the transmission terminal 100. In such a case, it becomes possible to store this application itself in the reception terminal 200, at the time when a user becomes interested in the application executed by the transmission terminal 100.

Additionally, the display control section 111 may have a function similar to that of the display control section 211. The control apparatus 300 includes an information acquisition section 311, a comparison section 312, and a transmission control section 313. The information acquisition section 311 acquires a feature amount of a display image displayed by one terminal out of the transmission terminal 100 and the reception terminal 200, and a feature amount of a captured image captured by the other terminal. Also, the comparison section 312 obtains a comparison result by comparing the feature amount of the display image and the feature amount of the captured image.

Further, the transmission control section 313 controls whether or not data is transmitted from the transmission terminal 100 to the reception terminal 200 in accordance with the comparison result. For example, in the case where the comparison result shows matching or similarities between the feature amount of the display image and the feature amount of the captured image, the transmission control section 313 may allow data to be transmitted from the transmission terminal 100 to the reception terminal 200.

Heretofore, a functional configuration example of the transmission terminal 100 according to the first embodiment of the present disclosure has been described.

<1-3. Functional configuration example of the reception terminal>
To continue, a functional configuration example of the reception terminal 200 according to the first embodiment of the present disclosure will be described. FIG. 6 is a figure which shows a functional configuration example of the reception terminal 200 according to the first embodiment of the present disclosure. As shown in FIG. 6, the reception terminal 200 includes a control section 210, an input section 220, an imaging section 230, a detection section 240, a storage section 250, a communication section 260, and a display section 270.

For example, the control section 210 corresponds to a processor such as a CPU (Central Processing Unit). The control section 210 exhibits the various functions of the control section 210, by executing programs stored in the storage section 250 or another storage medium. The control section 210 has a display control section 211, a captured image acquisition section 212, and a communication control section 213. Each of these functional sections of the control section 210 will be described afterwards.

The input section 220 has a function which accepts an operation from a user. The input section 220 outputs the operation accepted from the user to the control section 210. The operation can be used for the execution of a program. Further, for example, the input section 220 can accept an operation from the user which starts the activation of a program. Further, for example, the input section 220 can accept an operation from the user which completes the execution of a program. While the input section 220 is incorporated into the reception terminal 200 in the example shown in FIG. 6, the input section 220 may be present outside of the reception terminal 200.

The imaging section 230 acquires a captured image by capturing an imaging range, and outputs the captured image to the control section 210. The imaging section 230 performs imaging by imaging magnification set in accordance with an operation input to the input section 220. While an adjustment of the imaging magnification can be implemented by a zoom function, this zoom function is not particularly limited, and may be an optical zoom function, or may be an electronic zoom function. Note that, while the imaging section 230 is integrated with the reception terminal 200 in the example shown in FIG. 6, the imaging section 230 may be constituted separately from the reception terminal 200.

The detection section 240 detects prescribed sensor data, and outputs the detected sensor data to the control section 210. The detection section 240 has a GPS (Global Positioning System) antenna, and detects GPS data (latitude and longitude of the present position of the reception terminal 200) by using GPS signals received by the GPS antenna. Note that, the sensor data detected by the detection section 240 may be data other than GPS data. Further, while the detection section 240 is integrated with the reception terminal 200 in the example shown in FIG. 6, the detection section 240 may be constituted separately from the reception terminal 200.

The storage section 250 stores programs for operating the control section 210, by using a recording medium such as a semiconductor memory or a hard disk. Further, for example, the storage section 250 can store various types of data used by the programs (for example, various setting information, contents or the like). Note that, while the storage section 250 is integrated with the reception terminal 200 in the example shown in FIG. 6, the storage section 250 may be constituted separately from the reception terminal 200.

The communication section 260 is capable of communicating with the transmission terminal 100. The form of the communication by the communication section 260 is not particularly limited, and the communication by the communication section 260 may be wireless communication, or may be wired communication. Note that, while the communication section 260 is integrated with the reception terminal 200 in the example shown in FIG. 6, the communication section 260 may be constituted separately from the reception terminal 200.

The display section 270 performs display of various types of information, in accordance with a control by the control section 210. For example, the display section 270 may include an LCD (Liquid Crystal Display), or an organic EL (Electroluminescence) display apparatus. Or, the display section 270 may include an audio output apparatus such as a speaker or headphones. Note that, while the display section 270 is integrated with the reception terminal 200 in the example shown in FIG. 6, the display section 270 may be constituted separately from the reception terminal 200.

In the case where it is judged that a comparison result shows matching or similarities between a feature amount of a display image displayed by one terminal out of the reception terminal 200 and the transmission terminal 100, and a feature amount of a captured image captured by the other terminal, the communication control section 213 causes the communication section 260 to receive data from the transmission terminal 100. According to such a function of the communication control section 213, it becomes possible to reduce the possibility that incorrect data transmission is performed from the transmission terminal 100 to the reception terminal 200, while reducing the complexity of operations provided to the user. The display control section 211 displays a video image on the display section 270, based on the data received from the transmission terminal 100.

Heretofore, a functional configuration example of the reception terminal 200 according to the first embodiment of the present disclosure has been described.

<1-4. Operation examples of the control system>
To continue, an operation example of the control system 10 according to the first embodiment of the present disclosure will be described. FIG. 7 is a sequence diagram which shows an operation example of the control system 10 according to the first embodiment of the present disclosure. In particular, the example shown in FIG. 7 corresponds to an example in which the transmission terminal 100 selects a connection partner. Further, the example shown in FIG. 7 corresponds to an example in which the transmission terminal 100 displays an image and the reception terminal 200 captures an image, and corresponds to an example in which the data transmitted from the transmission terminal 100 to the reception terminal 200 is a video image Im1.

First, the communication control section 113 in the transmission terminal 100 transmits a detection signal for detecting a terminal in the surroundings, and the communication control section 213 in the reception terminal 200 transmits a detection signal for detecting a terminal in the surroundings (S101). The communication control section 213 controls the communication section 260 so as to notify the terminal in the surroundings that connection to a camera is possible (S102). Note that, it may not be necessary to notify that connection to a camera is possible.

To continue, the display control section 111 displays an image on the display section 170 (S103), and when a feature amount of the display image is extracted (S104), the communication control section 113 controls the communication section 160 so that the feature amount of the display image is transmitted to the terminal in the surroundings (S108). On the other hand, an image is captured by the imaging section 230 (S105), a feature amount of the captured image is extracted by the captured image acquisition section 212 (S107), and when the feature amount of the display image and the feature amount of the captured image are acquired by the information acquisition section 311, the comparison section 312 compares both feature amounts (S110).

To continue, in the case where the reception terminal 200 which receives the detection signal is present, the transmission control section 313 controls the communication section 160 so that a connection request is transmitted to this reception terminal 200 (S109). In the case where it is judged that a comparison result shows matching or similarities when the communication control section 213 controls the communication section 260 so that the connection request is received from the transmission terminal 100, the communication control section 213 controls the communication section 260 so that a connection response is transmitted to the transmission terminal 100 (S111), and the communication control section 113 controls the communication section 160 so that a confirmation message is transmitted to the reception terminal 200 (S112).

To continue, when an authentication, WPS (registered trademark) and association are performed between the transmission terminal 100 and the reception terminal 200 (S113, S114 and S115), and an RTP (Real-time Transport Protocol) session is established in an RTSP (Real Time Streaming Protocol) (S116), the communication control section 113 controls the communication section 160 so that a video image Im1 is transmitted to the reception terminal 200 by the RTP (S117), and when the communication control section 213 controls the communication section 260 so that the video image Im1 is received from the transmission terminal 100, the display control section 211 displays the video image Im1 on the display section 270.

While an image is captured by the imaging section 230 in the above described example, the display control section 211 may display a video image Im0 captured by the imaging section 230 on the display section 270, such as shown in FIG. 7. In such a case, when data is received from the transmission terminal 100, the display control section 211 performs a transition of the display by the display section 270 from the video image Im0 captured by the imaging section 230 to the video image Im1 based on data received from the transmission terminal 100.

In the above described general technology, since the video image Im1 is suddenly displayed based on data received from the transmission terminal 100, it may be difficult for the user to intuitively understand what process is being executed. Compared to such general technology, if an image displayed by the transmission terminal 100 is captured and displayed on the reception terminal 200, it will be easier for the user to intuitively understand that data is being transmitted from the transmission terminal 100 to the reception terminal 200.

The display image displayed by the transmission terminal 100 and the captured image captured by the reception terminal 200 may be still images or may be moving images. Here, it will be assumed that time may be necessary to some extent from the display image being displayed up until the captured image is captured. Therefore, in the case where the display image and the captured image are moving images, and in the case where a difference between the time when the display image is acquired and the time when the captured image is acquired is within a prescribed range, the comparison section 312 may compare a feature amount of the display image and a feature amount of the captured image.

Further, while an application may be executed from the beginning in the reception terminal 200, in the case where the application has already been partway executed in the transmission terminal 100, the application may not be executed from the beginning in the reception terminal 200. Accordingly, the data transmitted to the reception terminal 200 may include at least an application execution state in the transmission terminal 100 and a file generated by an application execution. In such a case, it becomes possible for an application to be executed in the reception terminal 200 from a continuation of an execution of the application in the transmission terminal 100 based on the application execution state and the file. Note that, at the time of application execution, the application execution state is stored in the RAM 803, and the file generated by the application execution is stored in the storage apparatus 811.

The display by the reception terminal 200 may be changed according to whether or not communication between the transmission terminal 100 and the reception terminal 200 is possible via the wireless LAN. For example, in the case where the data received from the transmission terminal 100 includes at least a video image, an application execution state and a file generated by an application execution, the display control section 211 switches the display by the display section 270 from the video image to an execution result of an application based on the application result state and the file, in the case where the distance between the transmission terminal 100 and the reception terminal 200 becomes greater than a prescribed distance. According to such a configuration, it becomes possible to resume an image display in the reception terminal 200, even in the case where communication via the wireless LAN is not possible.

FIG. 8 is a sequence diagram which shows an operation example of the control system 10 according to the first embodiment of the present disclosure. In particular, the example shown in FIG. 8 corresponds to an example in which the reception terminal 200 selects a connection partner. Further, the example shown in FIG. 8 corresponds to an example in which the transmission terminal 100 displays an image and the reception terminal 200 captures an image, and corresponds to an example in which the data transmitted from the transmission terminal 100 to the reception terminal 200 is a video image Im1.

S101 to S108 and S110 shown in FIG. 8 can be executed the same as S101 to S108 and S110 shown in FIG. 7. Further, S113 to S117 shown in FIG. 8 can be executed the same as S113 to S117 shown in FIG. 7. Therefore, here, S109, S111 and S112 shown in FIG. 8 will be mainly described.

When a comparison of both feature amounts by the comparison section 312 ends, in the case where the transmission terminal 100 which receives a detection signal is present, and in the case where it is judged that the comparison result of the feature amounts shows matching or similarities, the transmission control section 313 controls the communication section 260 so that a connection request is transmitted to this transmission terminal 100 (S109). When the communication control section 113 controls the communication section 160 so that the connection request is received from the reception terminal 200, the communication control section 113 controls the communication section 160 so that a connection response is transmitted to the reception terminal 200 (S111), and the communication control section 213 controls the communication section 260 so that a confirmation message is transmitted to the transmission terminal 100 (S112).

FIG. 9 is a sequence diagram which shows an operation example of the control system 10 according to the first embodiment of the present disclosure. In particular, the example shown in FIG. 9 corresponds to an example in which the transmission terminal 100 captures an image, and the reception terminal 200 displays an image. Further, the example shown in FIG. 9 corresponds to an example in which the data transmitted from the transmission terminal 100 to the reception terminal 200 is a video image Im1.

S101 and S102 shown in FIG. 9 can be executed the same as S101 and S102 shown in FIG. 7 or FIG. 8. Further, S108 to S117 shown in FIG. 9 can be executed the same as S108 to S117 shown in FIG. 7 or FIG. 8. Therefore, here, S103 to S107 shown in FIG. 9 will be mainly described.

In the example shown in FIG. 9, the display control section 211 displays an image on the display section 270 (S103), and extracts a feature amount of the display image (S104). On the other hand, an image is captured by the imaging section 130 (S105), and when a feature amount of the captured image is extracted by the captured image acquisition section 112 (S107), the communication control section 113 controls the communication section 160 so that the feature amount of the captured image is transmitted to a terminal in the surroundings (S108).

While the image is displayed by the display section 270 in the above described example, the display control section 211 may display a prescribed image Im2 on the display section 270, such as shown in FIG. 9. The image Im2 can be any type of image, and may be an image obtained by capturing some terminal, such as shown in FIG. 9. In such a case, when data is received from the transmission terminal 100, the display control section 211 may perform a transition of the display by the display section 270 from the image Im2 to a video image Im1 based on data received from the transmission terminal 100.

FIG. 10 is a sequence diagram which shows an operation example of the control system 10 according to the first embodiment of the present disclosure. In particular, the example shown in FIG. 10 corresponds to an example in which a video image and an application are transmitted in parallel. In the example shown in FIG. 10, S101 to S117 shown in FIG. 7 to FIG. 9 have already been executed, and the operations which can be additionally performed after this will be mainly described.

While a video image can be transmitted from the transmission terminal 100 to the reception terminal 200 (S117, S122), an application, an application execution state and a file generated by an application execution may be transmitted from the transmission terminal 100 to the reception terminal 200 in parallel with the video image. In such a case, a distance between the transmission terminal 100 and the reception terminal 200 is determined (S123), and in the case where the distance between the transmission terminal 100 and the reception terminal 200 becomes greater than a prescribed distance, the display control section 211 may perform a transition of the display by the display section 270 from the video image to an execution result of the application based on the application execution state and the file (S124).

In this example, in the case where the data received from the transmission terminal 100 includes at least a video image, an application, an application execution state and a file generated by an application execution, the display control section 211 may perform preparations for displaying an execution result of the application based on the application execution state and the file while displaying the video image on the display section 270, and may switch the display by the display section 270 from the video image to the execution result of the application at the time when a prescribed timing is reached. According to such a configuration, it becomes possible for video image display to be smoothly continued in the reception terminal 200, even in the case where communication via the wireless LAN is not possible.

FIG. 11 is a sequence diagram which shows an operation example of the control system 10 according to the first embodiment of the present disclosure. In particular, the example shown in FIG. 11 corresponds to an example in which a transmission line of data is switched. In the example shown in FIG. 11, S101 to S117 shown in FIG. 7 to FIG. 9 have already been executed, and the operations which can be additionally performed after this will be mainly described.

A case will be assumed in which communication via the wireless LAN is not possible while data is transmitted from the transmission terminal 100 to the reception terminal 200 via the wireless LAN. Accordingly, a distance between the transmission terminal 100 and the reception terminal 200 is determined (S131), and in the case where the distance between the transmission terminal 100 and the reception terminal 200 becomes greater than a prescribed distance, the display control section 211 may transmit a transmission line switching instruction to the transmission terminal 100 (S132). Further, when the transmission terminal 100 receives the transmission line switching instruction, the transmission terminal 100 may switch the transmission line so as to transmit data via a public wireless network (S133, S134).

In this example, in the case where the distance between the transmission terminal 100 and the reception terminal 200 becomes greater than a prescribed distance, the communication control section 113 may switch the transmission line of data transmitted by the communication section 160 from the wireless LAN to a public wireless network. According to such a configuration, it is possible to continue to transmit data from the transmission terminal 100 to the reception terminal 200, even in the case where communication via the wireless LAN is not possible. Note that, while the video image can be transmitted from the transmission terminal 100 to the reception terminal 200, an application, an application execution state and a file generated by an application result may be transmitted from the transmission terminal 100 to the reception terminal 200 in parallel with the transmission of the video image. The display control section 211 may perform preparations for displaying an execution result of the application based on the application execution state and the file while displaying the video image on the display section 270, and may switch the display by the display section 270 from the video image to the execution result of the application at the time when a prescribed timing is reached. According to such a configuration, it becomes possible for video image display to be smoothly continued in the reception terminal 200, even in the case where communication via the wireless LAN is not possible.

Heretofore, operation examples of the control system 10 according to the first embodiment of the present disclosure have been described.

On the other hand, when the feature amount of the display image and the feature amount of the captured image are acquired by the information acquisition section 311, the comparison section 312 compares both feature amounts (S110).

When a comparison of both feature amounts by the comparison section 312 ends, in the case where the reception terminal 200 which receives a detection signal is present, and in the case where it is judged that the comparison result of the feature amounts shows matching or similarities, the transmission control section 313 controls the communication section 160 so that a connection request is transmitted to this reception terminal 200 (S109).

To continue, a functional configuration example of the server apparatus 400 according to the third embodiment of the present disclosure will be described. FIG. 18 is a figure which shows a functional configuration example of the server apparatus 400 according to the third embodiment of the present disclosure. As shown in FIG. 18, the server apparatus 400 includes a control section 410, a storage section 450, and a communication section 460. As described above, in the third embodiment of the present disclosure, the server apparatus 400 includes the control apparatus 300 instead of the transmission terminal 100 or the reception terminal 200.

For example, the control section 410 corresponds to a processor such as a CPU (Central Processing Unit). The control section 410 exhibits the various functions of the control section 410, by executing programs stored in the storage section 450 or another storage medium.

The storage section 450 stores programs for operating the control section 410, by using a recording medium such as a semiconductor memory or a hard disk. Further, for example, the storage section 450 can store various types of data used by the programs (for example, various setting information, contents or the like). Note that, while the storage section 450 is integrated with the server apparatus 400 in the example shown in FIG. 18, the storage section 450 may be constituted separately from the server apparatus 400.

The communication section 460 is capable of communicating with the transmission terminal 100 and the reception terminal 200. The form of the communication by the communication section 460 is not particularly limited, and the communication by the communication section 460 may be wireless communication, or may be wired communication.

<3-4. Operation example of the control system>
To continue, an operation example of the control system 10 according to the third embodiment of the present disclosure will be described. FIG. 19 is a sequence diagram which shows an operation example of the control system 10 according to the third embodiment of the present disclosure. In particular, the example shown in FIG. 19 corresponds to an example in which the transmission terminal 100 selects a connection partner. Further, the example shown in FIG. 19 corresponds to an example in which the transmission terminal 100 displays an image and the reception terminal 200 captures an image, and corresponds to an example in which the data transmitted from the transmission terminal 100 to the reception terminal 200 is a video image Im1.

S113 to S117 shown in FIG. 19 can be executed the same as S113 to S117 shown in FIG. 7. Therefore, here, S101 to S112 shown in FIG. 19 will be mainly described.

To continue, the display control section 111 displays an image on the display section 170 (S103), and when a feature amount of the display image is extracted (S104), the communication control section 113 controls the communication section 160 so that the feature amount of the display image and additional information are transmitted to the server apparatus 400 (S108A). On the other hand, an image is captured by the imaging section 230 (S105), and when a feature amount of the captured image is extracted by the captured image acquisition section 212 (S107), the communication control section 213 controls the communication section 160 so that the feature amount of the captured image and additional information are transmitted to the server apparatus 400 (S108B).

Here, the additional information is information additionally used other than the feature amount, and may be sensor data (for example, position information, reception intensities of electric waves, or a feature amount of audio data) detected by the detection section 140, or may be an IP address.

In this way, in the case where the information acquisition section 311 acquires additional information from the transmission terminal 100 and acquires additional information from the reception terminal 200, the comparison section 312 may additionally compare the additional information acquired from the transmission terminal 100 and the additional information acquired from the reception terminal 200. According to such a configuration, it becomes possible to further reduce the possibility that incorrect data transmission is performed from the transmission terminal 100 to the reception terminal 200, compared to the case where only the feature amounts are to be compared.

Note that, since the additional information is information additionally used other than the feature amounts, it is not information which may necessarily have to be provided. When a feature amount and additional information are acquired from the transmission terminal 100 and a feature amount and additional information are acquired from the reception terminal 200 by the information acquisition section 311, the comparison section 312 compares both feature amounts and both additional information (S110).

To continue, in the case where the reception terminal 200 which receives a detection signal is present, the transmission control section 313 controls the communication section 160 so that a connection request is transmitted to this reception terminal 200 (S109). When the communication control section 213 controls the communication section 260 so that the connection request is received from the transmission terminal 100, in the case where it is judged that a comparison result between the feature amounts shows matching or similarities, and a comparison result between the additional information shows matching or similarities, the communication control section 213 controls the communication section 260 so that a connection response is transmitted to the transmission terminal 100 (S111), and the communication control section 113 controls the communication section 160 so that a confirmation message is transmitted to the reception terminal 200 (S112).

Heretofore, an operation example of the control system 10 according to the third embodiment of the present disclosure has been described.
