<1. First embodiment>
(1-1. Overview of System 1)
An overview of the functions provided by the system 1 (hereinafter also referred to as the functions) will be described with reference to Fig. 1. As shown in Fig. 1, the system 1 includes a terminal device 10 used by a user, a server 20, and a display device 30. The user U uses the terminal device 10 to capture images (including still images and videos). The terminal device 10 transmits the captured images to the server 20.

The server 20 determines whether the received image is an image to be preferentially displayed on the display device 30 (hereinafter also referred to as a priority image). The server 20 transmits the image determined to be a priority image to the display device 30. The display device 30 preferentially displays the priority image received from the server 20.

In this way, in system 1, server 20 receives an image captured by a user and determines whether the image is a priority image. Images determined to be priority images are transmitted from server 20 to display device 30 and are displayed preferentially by display device 30. Details are described below.

(1-2. Hardware configuration of system 1)
Fig. 2 is a block diagram showing an example of a hardware configuration of the system 1. The system 1 includes a plurality of terminal devices 10, a server 20, and a display device 30. The terminal devices 10, the server 20, and the display device 30 are communicatively connected via a network 40. Note that in Fig. 2, the system 1 is illustrated as including one terminal device 10 from the viewpoint of visibility, but the number of terminal devices 10 is not limited to this example, and may be two or more.

In this embodiment, a collection of multiple devices may be one server 20. The method of allocating multiple functions required to realize the server 20 of this embodiment to one or more pieces of hardware can be determined appropriately in consideration of the processing capacity of each piece of hardware and/or the specifications required for the server 20.

The terminal device 10 is realized as a mobile terminal such as a smartphone, or a tablet terminal. The terminal device 10 includes a communication IF (Interface) 12, an input device 13, an output device 14, a memory 15, a storage 16, and a processor 19.

The communication IF 12 is an interface for inputting and outputting signals so that the terminal device 10 can communicate with external devices.

The input device 13 is a device (e.g., a touch panel, a microphone, etc.) for accepting input operations from the user.

The output device 14 is a device (display, speaker, etc.) for presenting information to the user.

Memory 15 is used to temporarily store programs and data processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory).

Storage 16 is used to store data, and is, for example, a flash memory or a hard disk drive (HDD).

The processor 19 is hardware for executing the instruction set described in the program, and is composed of an arithmetic unit, registers, peripheral circuits, etc.

The server 20 is a computer capable of communicating with the terminal device 10 and the display device 30 via a network 40 such as the Internet, and may be realized as a so-called cloud server, or may be realized as an on-premise server installed at a specific venue. The server 20 includes a communication IF 22, an input/output IF 24, a memory 25, a storage 26, and a processor 29.

The input/output IF 24 is an interface for connecting an input/output device when performing some input operation on the server 20 or when outputting information from the server 20.

The communication IF 22, memory 25, storage 26 and processor 29 are configured in the same manner as the communication IF 12, memory 15, storage 16 and processor 19 of the terminal device 10, and therefore will not be described repeatedly.

The display device 30 may be configured as an image display device equipped with a display unit such as a display, or may be configured as a video projection device such as a projector that projects an image onto a display unit such as a screen. In either case, the display device 30 may be configured to receive an image from the server 20 and include a communication IF, a processor, a memory, etc. for displaying the image on the display unit, and any well-known image display device or video projection device may be used.

(1-3. Functional configuration of terminal device 10)
Fig. 3 is a block diagram showing an example of a functional configuration of the terminal device 10. As shown in Fig. 3, the terminal device 10 includes an input device 13, an output device 14, a communication unit 150, an imaging unit 160, an audio processing unit 170, a storage unit 180, a position information sensor 190, and a control unit 200. The blocks included in the terminal device 10 in Fig. 3 are electrically connected to each other by, for example, a bus or the like.

The communication unit 150 performs processing such as modulation and demodulation processing for the terminal device 10 to communicate with other devices. The communication unit 150 performs transmission processing on the signal generated by the control unit 200 and transmits it to the outside (e.g., another terminal device 10). The communication unit 150 performs reception processing on the signal received from the outside and outputs it to the control unit 200.

The input device 13 is a device for inputting instructions or information by the user operating the terminal device 10. The input device 13 is realized, for example, by a touch-sensitive device 131 or the like that inputs instructions by touching the operation surface. The input device 13 may include a keyboard or a mouse. The input device 13 converts the instructions or information input by the user into an electrical signal and outputs the electrical signal to the control unit 200. The input device 13 may also include, for example, a receiving port that receives an electrical signal input from an external input device.

The output device 14 is a device for presenting information to a user who operates the terminal device 10. The output device 14 is realized, for example, by a display 141 or the like. The display 141 displays data according to the control of the control unit 200. The display 141 is realized, for example, by an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display or the like.

The imaging unit 160 is equipped with a camera, receives light using a light receiving element, and inputs the light as an imaging signal to capture an image of the surroundings of the terminal device 10.

The audio processing unit 170, for example, performs digital-to-analog conversion processing of an audio signal. The audio processing unit 170 converts a signal provided from the microphone 171 into a digital signal and provides the converted signal to the control unit 200. The audio processing unit 170 also provides an audio signal to the speaker 172. The audio processing unit 170 is realized, for example, by a processor for audio processing. The microphone 171 accepts audio input and provides an audio signal corresponding to the audio input to the audio processing unit 170. The speaker 172 converts the audio signal provided from the audio processing unit 170 into audio and outputs the audio to the outside of the terminal device 10.

The memory unit 180 is realized, for example, by the memory 15 and the storage 16, and stores data and programs used by the terminal device 10.

The position information sensor 190 is a sensor that detects the position of the terminal device 10, and is, for example, a GPS (Global Positioning System) module. The GPS module is a receiving device used in a satellite positioning system. In a satellite positioning system, signals are received from at least three or four satellites, and the current position of the terminal device 10 equipped with the GPS module is detected based on the received signals. Note that the position information sensor 190 may also use a satellite positioning system other than GPS, for example a system called GNSS (Global Navigation Satellite System).

The control unit 200 is realized by the processor 19 reading a program stored in the storage unit 180 and executing instructions contained in the program. The control unit 200 controls the operation of the terminal device 10. By operating according to the program, the control unit 200 fulfills the functions of an operation reception unit 201, a transmission/reception unit 202, a display control unit 203, and a position information acquisition unit 204.

The operation reception unit 201 performs processing for receiving instructions or information input from the input device 13. Specifically, for example, the operation reception unit 201 receives information based on instructions input from the touch-sensitive device 131, etc.

The transmission/reception unit 202 performs processing for the terminal device 10 to transmit and receive data to and from external devices in accordance with a communication protocol.

The display control unit 203 controls the display of information to be notified to the user on the display 141.

The location information acquisition unit 204 acquires location information of the terminal device 10. Specifically, for example, the location information acquisition unit 204 acquires location information of the terminal device 10 acquired by the location information sensor 190. Details of the processing in each function of the control unit 200 will be described later.

(1-4. Functional configuration of server 20)
4, the server 20 includes a communication unit 210, a storage unit 220, and a control unit 230. The blocks included in the server 20 in FIG. 4 are electrically connected to each other, for example, by a bus. The server 20 may also be appropriately connected to input/output devices such as a keyboard 241 and a display 242 via the input/output IF 24.

The communication unit 210 performs processing for the server 20 to communicate with external devices.

The storage unit 220 is realized, for example, by the memory 25 and the storage 26, and stores data and programs used by the server 20. The storage unit 220 stores an image database 221 and a priority condition database 222.

The image database 221 is a database for storing information about images received from the terminal device 10. As an example, the image database 221 may be configured such that, when an image is received from the terminal device 10, a new record corresponding to that image is added. Details of the data structure of the image database 221 will be described later.

The priority condition database 222 is a database for storing information about priority conditions for determining whether or not an image received from the terminal device 10 is to be a priority image. As an example, the priority condition database 222 may be configured such that records are generated when a user registers priority conditions using software that provides this function installed on the server 20. The data structure of the priority condition database 222 will be described in detail later.

The control unit 230 is realized by the processor 29 reading a program stored in the storage unit 220 and executing instructions contained in the program. The control unit 230 operates according to the program and includes a transmission/reception module 231, an image registration module 232, and an image determination module 233.

The transmission/reception module 231 performs processing for the server 20 to transmit and receive data with external devices in accordance with a communication protocol.

The image registration module 232 stores the images received by the transmission/reception module 231 from the terminal device 10 in the image database 221 of the memory unit 220.

The image determination module 233 determines whether an image stored in the image database 221 is a priority image. Specifically, for example, the image determination module 233 performs image recognition processing on the images stored in the image database 221. Well-known techniques such as pattern recognition, differential image calculation, and template matching may be used for the image recognition processing. Furthermore, when performing these image recognition processes, the image determination module 233 may appropriately utilize AI (artificial intelligence) techniques such as machine learning and deep learning, and may be configured to improve the accuracy of image recognition by constructing a learning model. The image determination module 233 performs these image recognition processes on the images stored in the image database 221 to determine whether the images correspond to priority images.

(1-5. Data Structure)
5, the data structure of the database used in the system 1 will be described. Note that the data structure described below is merely an example, and does not exclude the possession of other databases and data items.

Figure 5 shows an example of the data structure of the image database 221 and the priority condition database 222 stored in the memory unit 220 of the server 20.

As shown in FIG. 5, a record in the image database 181 includes the items "image ID," "content," "file format," "location of transmission," and "transmission date and time," etc.

The "Image ID" item is identification information for identifying an image and is the primary key for uniquely identifying a record in the image database 221.

The "Content" item is information about the content of the image. In this embodiment, images include still images and videos.

The "File format" item is information about the file format of the image. Specifically, if the image is a still image, information specifying the file format, such as JPG, GIF, or PNG, may be stored. Also, if the image is a video, information specifying the file format, such as MOV, MP4, or WEVM may be stored.

The item "location of origin" is information about the location from which the terminal device 10 transmitted the image. The transceiver 202 of the terminal device 10 may transmit the location information acquired by the location information acquisition unit 204 of the terminal device 10 to the server 20 together with the image, and the image registration module 232 of the server 20 may store the location information in the item "location of origin" of the image database 221.

The item "Date and time of transmission" is information about the date and time when the terminal device 10 transmitted the image. The transceiver unit 202 of the terminal device 10 may transmit time information obtained from a clock built into the terminal device 10 to the server 20 together with the image, and the image registration module 232 of the server 20 may store the time information in the item "Date and time of transmission" of the image database 221.

The image database 221 may be configured such that, when an image is received from the terminal device 10, the image registration module 232 adds a new record corresponding to the received image.

A record in the priority condition database 222 includes an item "condition ID," an item "condition content," an item "target data," an item "necessity of application," an item "registration date and time," etc.

The item "Condition ID" is identification information for identifying the priority condition and is a primary key for uniquely identifying a record in the priority condition database 222.

The item "condition content" is information about the content of the priority conditions. Examples of the content of the priority conditions include the following:
The image received from the terminal device 10 includes the name or logo of a specific company, organization such as a local government, or a brand (brand) of a product (hereinafter referred to as condition A).
- A specified item is shown in the image received from the terminal device 10 (hereinafter referred to as condition B).
A specific person appears in the image received from the terminal device 10 (hereinafter, referred to as condition C).
The colors used in the image received from the terminal device 10 satisfy a predetermined condition (hereinafter, referred to as condition D).

Condition A may be such that if the size of the name or logo in an image satisfies a specified condition, the image is determined to be a priority image. Here, the size of the name or logo may be determined based on the proportion of the image it occupies (i.e., the relative size), or it may be determined based on the absolute size of the name or logo when the image size is set to a specified value.

In addition, under condition B, the specified item may be a product manufactured by a specified company (e.g., beer manufactured by a specific company), or the specification may be such that an image is determined to be a priority image if it contains a specific item (e.g., beer) without specifying the manufacturer.

In addition, in condition C, the specified person may be determined by performing facial recognition on the image. Also, the specification may be such that an image including the name of the specified person (for example, an image in which the name of the person in the image is displayed by naming (tagging) the person in the image) is set as the priority image.

In addition, in condition D, when determining whether a specific color satisfies a specific condition, the specification may be such that whether or not the image is a priority image is determined based on the color value in a specific color space (color system) or color temperature. The specific condition may be that a specific color is used at a specific rate or more, or that a specific combination of multiple colors is used (for example, the combination of colors used in a specific national flag is used).

The item "Target Data" is information for specifying the data to which the priority condition is applied, and as an example, holds information for specifying a still image or video (e.g., file format). In this manner, in this embodiment, the system is configured to allow selection of the conditions to be applied by specifying the file format.

The item "Need to apply" is information in the form of a flag indicating whether or not the condition is to be applied when the image determination module determines the priority image. Specifically, information specifying "apply" or "do not apply" is stored as need to apply. In this way, by making it possible to appropriately set whether or not to apply each condition stored in the priority condition database 222, the user can select conditions according to the event being held, and image display can be realized that matches the purpose of the event.

The "Registration Date and Time" item is information about the date and time the record was created.

As an example, the priority condition database 222 may be generated with records prepared as initial settings when software that provides this function is installed on the server 20. The software may also be used by a user to update the contents of each item in the records of the priority condition database 222. Specifically, the priority condition to be applied to a specific event may be selected by updating the item "Application required/unrequired." The software may also be used by a user to register new information related to priority conditions and add records to the priority condition database 222.

(1-6. Processing flow)
An example of the processing of the system 1 will be described below with reference to Figures 6 and 7. Note that in this embodiment, the system 1 is designed to allow a user to use the functions of the system 1 by accessing a website provided by the server 20.

In step S110, the transmission/reception unit 202 of the terminal device 10 transmits a request to access the website to the server 20 based on the user's operation. In step S210, the transmission/reception module 231 of the server 20 receives the request from the terminal device 10.

In step S220, the transmission/reception module 231 of the server 20 transmits the website information to the terminal device 10. In step S120, the transmission/reception unit 202 of the terminal device 10 receives the website information from the server 20.

In step S130, the operation reception unit 201 of the terminal device 10 receives an operation to select an image from the user. In the operation to select an image, an image captured by the user using the imaging unit 160 of the terminal device 10 may be selected. Alternatively, an image stored in the storage unit 180 may be selected by the user's operation.

In step S140, the transceiver unit 202 of the terminal device 10 transmits the selected image to the server 20. In step S230, the transceiver module 231 of the server 20 receives the selected image.

In step S240, the image registration module 232 of the server 20 stores the image received by the transmission/reception module 231 in the image database 221. In step S250, the image determination module 233 performs image determination processing on the image stored in the image database 221, by referring to the priority condition database 222, to determine whether the image is a priority image.

The flow of the image determination process (S250) will be described with reference to FIG. 7. In the example of the image determination process shown in FIG. 7, steps S251 to S256 are executed. Note that, although this example shows an example in which four conditions, condition A to condition D, are applied, the present invention is not limited to this form. In other words, the number and contents of the conditions applied in the image determination process (S250) are changed as appropriate depending on the records stored in the priority condition database 222 (specifically, the items "Condition contents" and "Application required").

In step S251, the image determination module 233 of the server 20 determines whether an image stored in the image database 221 satisfies condition A, i.e., whether the image contains the name or logo of a specified company, organization such as a local government, or a brand of a product, etc.

Specifically, the image judgment module 233 performs a predetermined image recognition process on the image to be judged, and judges whether or not the image satisfies condition A. If it is judged that the image to be judged satisfies condition A (YES in S251), step S256 is performed. On the other hand, if it is judged that the image to be judged does not satisfy condition A (NO in S251), step S252 is performed.

In step S252, the image determination module 233 determines whether the image to be determined satisfies condition B, i.e., whether a specified item is shown in the image.

Specifically, a predetermined image recognition process is performed on the image to be judged, and it is determined whether or not the image satisfies condition B. If it is determined that the image to be judged satisfies condition B (YES in S252), step S256 is performed. On the other hand, if it is determined that the image to be judged does not satisfy condition A (NO in S252), step S253 is performed.

In step S253, the image determination module 233 determines whether the image to be determined satisfies condition C, i.e., whether a specified person is captured in the image.

Specifically, a predetermined image recognition process is performed on the image to be judged, and it is determined whether or not the image satisfies condition C. If it is determined that the image to be judged satisfies condition C (YES in S253), step S256 is performed. On the other hand, if it is determined that the image to be judged does not satisfy condition C (NO in S253), step S254 is performed.

In step S254, the image determination module 233 determines whether the image to be determined satisfies condition D, i.e., whether the colors used in the image satisfy a predetermined condition.

Specific processing involves performing a predetermined image analysis process on the image to be judged, and judging whether or not the image satisfies condition D. If it is judged that the image to be judged satisfies condition D (YES in S254), step S256 is performed. On the other hand, if it is judged that the image to be judged does not satisfy condition A (NO in S254), step S255 is performed.

In step S255, the image determination module 233 determines that the image being determined does not satisfy any of conditions A to D and is therefore not a priority image, and then accepts a check by the administrator. In a check by the administrator, for example, the user hosting the event checks whether the image being determined is to be output to the display device 30. This check may be performed, for example, using the keyboard 241 and display 242 attached to the server 20. Thus, in step S255, images determined not to be priority images are further sorted into those to be output and those not to be output.

In step S256, the image determination module 233 determines that the image being determined is a priority image because it satisfies at least one of conditions A to D. A priority image is an image that is displayed preferentially on the display device 30. In this way, the image determination process (S250) determines whether or not the images stored in the image database 221 are images that are to be displayed preferentially on the display device 30, and further accepts a check by the administrator as to whether or not images that are not priority images are to be output. By performing the image determination process, images received from the user's terminal device 10 are sorted into output images to be displayed on the display device 30 (including priority images and images that are not priority images but have been checked by the administrator to be output) and images that are not to be output.

When the image determination process (S250) is completed, in step S260 of FIG. 6, the transceiver 202 of the terminal device 10 transmits the image (output image) determined to be output in the image determination process (S250) to the display device 30. In step S310, the display device 30 receives the output image from the terminal device 10. In step S320, the display device 30 displays the output image.

Note that in step S255 of the image determination process (S250), since an administrator checks the image, it is expected that the process will take some time. Therefore, it is preferable that an image determined to be a priority image is given priority in the image determination process (S250) and the subsequent processes (S260 to S320) are carried out. This configuration encourages images determined to be priority images to be displayed preferentially on the display device 30.

(1-7. Summary)
As described above, in this embodiment, the computer executes the steps of accepting an image selection from a user (S130, S230), judging whether the accepted image is a priority image based on a predetermined condition (S250), and preferentially outputting the image judged to be a priority image (S320). With this configuration, images can be displayed appropriately according to the purpose of the event.

In addition, in the above embodiment, the images that are determined not to be priority images are further checked by the administrator (S255), making it possible to flexibly determine the images to be displayed on the display device 30 depending on the purpose, atmosphere, and excitement of the event. However, this is not limiting, and the administrator may not check (S255), and images other than priority images may not be displayed on the display device 30. Also, the control unit 230 may perform the check based on predetermined conditions.

(1-8. Modified Examples)
A modified example of the first embodiment will be described below. For example, the image determination module 233 may determine whether or not a person of a specific gender is included in an image as a priority condition for determining that the image is a priority image. In this case, a condition based on the ratio of genders in the image may be set. The image determination module 233 may also determine whether or not an image is a priority image based on the number of people in the image.

The image determination module 233 may also perform a determination based on the smile level of a person included in the image. Smile level is a parameter that quantitatively indicates the degree of smile in a person's facial expression (in other words, the possibility that it can be recognized as a smile), and can be calculated using known image recognition technology. The greater the degree of smile of a person in an image, the higher the smile level. In this case, if the smile value of a specific person in an image is equal to or greater than a predetermined threshold, the image may be determined to be a priority image. Also, if the average smile level of multiple people appearing in the image is higher than a predetermined threshold, the image may be determined to be a priority image.

The image determination module 233 may also be configured to determine that an image is a priority image if it contains a predetermined keyword. The predetermined keyword may be, for example, a keyword (hashtag) for grouping in a predetermined SNS, or a predetermined message (for example, a message expressing gratitude). The name of a specific event may also be selected as a keyword.

The image determination module 233 may also be configured to determine that an image similar to a specified image is a priority image. In this case, an image serving as a determination condition may be stored in the storage unit 220, and the image serving as the determination condition may be compared with the image to be determined to determine whether or not the image is a priority image.

The image determination module 233 may also be configured to determine whether an image to be determined is a priority image based on information about the location where the image was taken. In this case, for example, a specification is envisaged in which only images taken while actually participating in a particular event on-site are set as priority images. By using such a specification, only images accepted from users actually participating in the event can be displayed preferentially, improving the sense of realism at the event.

The image determination module 233 may also be configured to determine whether or not an image is a priority image based on information about the time when the image to be determined was captured. In this case, for example, a specification is envisaged in which the priority image is displayed on the display device 30 at a timing that matches the progress of a specific event. By using such a specification, images from event participants can be accepted in real time and shared among the participants, improving the user experience.

The image determination module 233 may also be configured to determine whether an image is a priority image or not based on the file format of the image to be determined. For example, only moving image files may be set as priority files, or only still image files may be set as priority files. By using such specifications, a sense of unity at the event can be created by standardizing the types of images displayed on the display device 30.

<2. Second embodiment>
A system 1 according to a second embodiment of the present disclosure will be described below with reference to Fig. 8 and Fig. 9. The following description will focus on differences from the above embodiment, and will not repeat the description of similar configurations.

The main screen 30a is larger in size than the auxiliary screen 30b and is placed at a central location of the event. The server 20 displays an image determined to be a priority image on the main screen 30a, and displays an image determined not to be a priority image on the auxiliary screen 30b.

The image determination process (S250) in the second embodiment will be described with reference to Fig. 9. Note that the description of the same processes as in the first embodiment will not be repeated.

In the second embodiment, an image that is not determined to be a priority image in steps S251 to S254 is set as a sub-image in step S255. The sub-image is an image displayed on the auxiliary screen 30b. In addition, an image that is determined to be a priority image in steps S251 to S254 is set as a main image in step S256. The main image is an image displayed on the main screen 30a.

When the image determination process (S250) is completed, in step S320, the main image is displayed on the main screen 30a and the sub-image is displayed on the auxiliary screen 30b.

This specification makes it possible to display all images received from users while assigning priority to the images, thereby improving the sense of unity among users participating in the event.

<3. Other embodiments>
Although the embodiment and the modified examples of the present invention have been described above, application of the present disclosure is not limited to the above-mentioned contents.

For example, in the above embodiment, the function is provided to the user by accessing a website, but the present invention is not limited to this form. For example, the function may be provided by installing software (a so-called app) on the terminal device 10, or in other ways.

In addition, in the above embodiment, an image is determined to be a priority image if it satisfies any one of priority conditions A to D, but this is not limited to the example, and an image may be determined to be a priority image if it satisfies multiple priority conditions.

For example, the control unit 230 of the server 20 may also be equipped with a priority calculation module for calculating the quantity (priority) of images determined to be priority images within a predetermined period (for example, within the period of a particular event). Here, the quantity may be the number of images, or the ratio of priority images to the images to be determined. The image determination module 233 may also be configured to calculate the smile level for the images to be determined, and further calculate the ratio of the smile level to the entire image. In this way, it is possible to measure the excitement level at the event.

In addition, for example, the priority conditions may be changeable while a particular event is being held. As an example, the event manager may use the keyboard 241 and display 242 attached to the server 20 to update the "Application Required" item in the priority condition database 222. The priority conditions may also be changeable by the image judgment module 233 based on the above-mentioned priority and/or smile degree ratio. With such specifications, it becomes possible to apply more appropriate conditions and display images with priority, taking into account the excitement level of the event, etc.

Furthermore, for example, the priority conditions to be applied may be changed depending on whether the image to be judged is a still image or a video. More specifically, the priority conditions to be applied may be changed depending on the file format of the image.

In addition, in the above embodiment, images taken by the user with the terminal device 10 and images stored in the terminal device 10 are transmitted to the server 20, but the present invention is not limited to this specification. For example, images uploaded by users participating in an event to external sites such as SNS during a specified period (e.g., the event period) may be acquired by the server 20 through crawling, and stored in the image database 221. For crawling, existing crawling tools such as Octoparse and Web Scraper may be used.

In addition, in the above embodiment, a display device 30 installed at an event or the like is assumed, but the present invention is not limited to this. For example, the priority image may be output by embedding a website in a specified application, or the priority image may be output by providing an API function. In addition, the priority image may be embedded and displayed at a specified position on a map on a website (for example, a position corresponding to the location where the image was taken).

The terminal device 10 is not limited to a tablet terminal or a mobile terminal such as a smartphone, but may be realized by a stationary PC (Personal Computer) or a laptop PC. In this case, the terminal device 10 may be realized by installing software on a home PC or the like, and may be configured to accept operations of a mouse, etc.

In addition, the sharing of specific information via a communication line is mainly performed via a WAN such as the Internet, but between information processing devices, the sharing may be performed only via short-range wireless communication such as Bluetooth (registered trademark) and infrared communication without using a WAN.

In addition, in the above embodiment, an example of a form in which each function is provided by the terminal device 10 or the server 20 is described, but this is not limited to this form, and some or all of the functions may be provided by the terminal device 10, the server 20, or both the terminal device 10 and the server 20 in a form different from the above embodiment.

In addition, each step described in the above embodiment as being executed by the terminal device 10 may be executed by the server 20, and each step described as being executed by the server 20 may be executed by the server 20.

Furthermore, the present invention may be realized as a program that causes an information processing device to execute the functions of the terminal device 10 or server 20 described above, or as a non-transitory computer-readable recording medium that stores the program.
