[Three-Party Coordination Processing Flow]
By the television 10, the smartphone 20 and the video camera 30 having the above functions,
A flow of three-party collaboration processing will be described. FIG. 7 is a flowchart for explaining the flow of the three-party cooperation processing of this embodiment. It is assumed that the relay table 500 and the link table 600 are created in advance.

Further, in the following, a case of selecting a desired moving image from the moving images recorded in the storage unit 34 of the video camera 30 by operating the smartphone 20 and displaying it on the display unit 13 of the television 10 will be taken as an example. to explain. However, it is not limited to this example. In addition to the instruction to select and display a moving image, for example, this cooperative processing can be similarly applied to an instruction to store a moving image or still image held by the video camera 30 in the storage unit 14 of the television 10. .

First, when the video camera 30 is connected to the television 10 via HDMI or the power of the video camera 30 already connected to the television 10 via HDMI is turned on (step S301), the video camera 30 is transmitted from the video camera 30 to the television 10. A trigger containing the device ID is sent.

In the television 10 , the connection detection unit 140 receives the notification of the device ID and transmits it to the remote controller determination unit 122 . Upon receiving the device ID, the remote controller determination unit 122 of the television 10 refers to the relay table 500 and performs relay application acquisition processing for acquiring a relay application (step S101).
, to get the relay app. Further, a remote controller determination process for determining the smartphone to be used as the remote controller is also performed (step S102), and the smartphone 20 is determined.

Then, the remote control determining unit 122 notifies the determined smartphone 20 of a connection instruction (step S103). Here, the device ID of the television 10 is stored in the smartphone 20
, notifies the device ID of the video camera 30 and transmits a command prompting the activation of the remote control application.

Here, the details of the relay application acquisition process in step S101 will be described with reference to FIG.

First, the remote controller determination unit 122 searches the relay table 500 (step S411),
It is determined whether or not the received device ID is registered (step S412). Here, if it is not registered, the three-party cooperation processing itself is terminated.

On the other hand, if it is registered, the remote controller determination unit 122 determines whether or not the relay application registered in association with the device ID 521 has been installed (step S413). If it has been installed, it is determined whether it is the latest version (step S
414). Whether or not it is the latest version is determined by accessing the server 90 via the Internet and comparing the version information registered as the relay application information with the provided latest version information.

If the latest version of the relay application is installed, the process ends. On the other hand, if the relay application is not installed, or if it is installed but not the latest version, remote controller determination unit 122 accesses server 90 via the Internet and downloads the latest version of the relay application (step S415). , install (step S4
16), the relay application acquisition process is terminated.

Note that the video camera 30 may hold the relay application, and the television 10 may acquire the relay application from the video camera 30 . Also, the version of the relay application stored in the server 90 and the version of the relay application stored in the video camera 30 may be compared, and a new one may be obtained as appropriate.

Further, in the above description, even if the relay application is installed, the server 90 is checked via the Internet as to whether or not it is the latest version, or the video camera 30 is contacted to always install the latest version. Configure. However, it is not necessary to confirm whether it is the latest version.

Also, in a state in which an old version of the relay application is stored in the video camera 30, if the latest version of the relay application is downloaded from the server 90 via the Internet, the television 1
0 may update an older version of the relay application stored in the video camera 30 with the latest version of the relay application obtained from the server 90 .

Next, the details of the remote controller determination process in step S102 will be described with reference to FIG.

The remote controller determination unit 122 first searches for a device that can be a remote controller within the same sub-network (sub NW) of the wireless LAN of the television 10 (step S421) and extracts it. Here, for example, smartphones are searched among various devices in the same sub NW.

Then, remote controller determination unit 122 searches relay table 500 (step S422).
, the smartphone extracted in step S421 contains the device I
It is determined whether or not there is a candidate smart phone registered in association with the video camera 30 having D (step S423).

If not registered, the three-party cooperation processing itself is terminated. Note that the user may be notified that there is no registered smartphone that can be used as a remote controller before the end.

On the other hand, if registered, the remote controller determination unit 122 determines the number of registered candidate smartphones (step S424).

If a plurality of smartphones are registered, the remote controller determination unit 122 selects the smartphone 20 to be used as the remote controller from among them (step S425), and determines the smartphone 20 to be used as the remote controller (step S426). The selection is made according to the techniques described above.

In step S424, if the number of registered smartphones is one, the candidate smartphone is determined to be the smartphone 20 to be used as a remote controller (step S426). After determining the smartphone 20 to be used as the remote controller, the remote controller determination unit 122 terminates the remote controller determination process.

Note that this remote control determination process is also executed when the connection with the smartphone 20 used as the remote control is interrupted for some reason during the execution of the three-party cooperation process.

Returning to FIG. 7, the remote control processing unit 220 of the smartphone 20 that has received the connection instruction performs remote control application acquisition processing (step S201).

Details of the remote control application acquisition process will be described with reference to FIG.

Using the notified device ID of the television 10 and the device ID of the video camera 30, the remote control processing unit 220 searches the linkage table 600 (step S431), and determines whether the remote control application associated with both is installed. is determined (step S432).

If the remote control application is installed, remote control processing unit 220 determines whether the version of the application is the latest version (step S433). Whether or not it is the latest version is determined by accessing the server 90 via the Internet and comparing version information registered as remote control application information with the provided latest version information.

If the remote control application is not installed, or if it is installed but not the latest version, remote control processing unit 220 accesses server 90 and downloads the latest version of the remote control application (step S434). and install it (
Step S435), the process ends.

As with the relay application described above, it is not necessary to determine whether or not it is the latest version. Furthermore, here, the remote control application has been described as being downloaded from the server 90, but it may be downloaded from the television 10 as well. In this case, various remote control apps can be
0 is stored in the storage area of the storage unit 14 in advance. Also, the version of the remote control application stored in the server 90 and the version of the remote control application stored in the television 10 may be compared and the newer version may be acquired. Also, a remote control application downloaded from the server 90 via the Internet may be stored in the storage area of the television 10 .

Returning to FIG. 7, after completing the remote control application acquisition process, the remote control processing unit 220 activates the remote control application and displays a remote control image on the touch panel 23 of the smartphone 20 (
step S202). Here, the displayed remote control image is displayed in a scrollable manner, and includes an operation display for selecting which of the television 10 or the video camera 30 is to be operated, a channel operation display, and a display for starting and stopping playback of recorded moving images. etc. are displayed.

An example of the displayed remote control image is shown in FIGS. 11(a) and 11(b). As shown in this figure, the remote control image 700 of this embodiment includes an operation target device selection area 710 and a remote control operation reception area 720 .

An operation target device selection area 710 accepts selection of a target device to be operated via this remote control image 700 . Either television 10 or video camera 30 is accepted here. For example, as shown in these figures, buttons are provided for accepting selections. Also, these buttons are displayed so that the selected device can be identified.

The operation screen of the device selected in the operation target device selection region 710 is displayed in the remote control operation reception region 720 . For example, when the television 10 is selected, a channel selection display or the like is performed. On the other hand, when the video camera 30 is selected, a screen is displayed for receiving instructions such as selection of a moving image to be reproduced, reproduction start, reproduction stop, and the like. In addition, regardless of which one is selected, the volume adjustment and the like are displayed in common.

Note that the remote control operation receiving area 720 may be configured so that the operation screen changes by scrolling. In this case as well, the device to be operated on the operation screen may be displayed in an identifiable manner in the operation target device selection area 710 .

Note that this remote control image 700 is merely an example, and how it is displayed depends on the
It varies depending on the functions implemented by each device. Also, for example, the display of device selection may be set to three or more. Also, a remote control image that integrates remote control operations for each device may be used. For example, it is an image that enables an instruction to record the image in the storage unit 14 of the television 10 at the same time as reproducing the moving image of the video camera 30 .

Returning to FIG. 7, when the remote control image is displayed on the touch panel 23, the remote control processing unit 220
instructs to transfer the moving image selection screen of the video camera 30 (step S203). This transfer instruction is transmitted from the smartphone 20 to the television 10 . Then, the relay unit 130 of the television 10 that receives the instruction transmits the instruction to the video camera 30 of the relay destination (step S104).

Upon receiving the transfer instruction, the video camera 30 transfers the data of the moving image selection screen to the television 10 (step S302). Note that the moving image selection screen is, for example, a screen for selecting moving images stored in the video camera 30 . The screen to be selected is, for example, an image displaying a thumbnail image of a moving image.

In the television 10 that has received the data of the moving image selection screen, the relay unit 130 displays the moving image selection screen of the video camera 30 on the display unit 13 according to the data (step S105).
Then, the relay unit 130 notifies the smartphone 20, which is the source of the transfer instruction, that the screen display has ended (step S106).

Upon receiving the screen display end notification, the remote control processing unit 220 of the smartphone 20 puts itself into a state capable of receiving a remote control operation from the user. This allows the user to give instructions to the video camera 30 while watching the moving image selection screen displayed on the display unit 13 of the television 10 .

When the remote control processing unit 220 receives an instruction (operation instruction) by an operation from the user,
The operation instruction is transmitted to the television 10 (step S204). The operation instruction received here is, for example, an instruction to reproduce the selected moving image. The moving image is selected, for example, from thumbnail images of moving images displayed as a moving image selection screen on the television 10 .

Upon receiving the operation instruction from the smartphone 20, the relay unit 130 of the television 10 relays the operation instruction to the video camera 30 (step S107).

Upon receiving the instruction, the video camera 30 transfers the data to the television 10 according to the operation instruction (step S303). For example, when an instruction to reproduce a predetermined moving image is received, the moving image data is transferred to the television 10 .

The relay unit 130 of the television 10 displays the transferred data on the display unit 13 (step S
108), a process end notification indicating that the relay process has ended is transmitted to the smartphone 20 (step S109). For example, when moving image data is received, display of the moving image is started.

In the smartphone 20 that has received the processing end notification, the remote controller processing unit 220 updates the remote controller image (step S205). When the remote control app has already been installed, the smartphone 20 that has received the connection instruction notified from the television 10 in step S103 does not prompt the automatic activation of the remote control app, and instead changes the color of the icon of the remote control app. The user may be notified that there is a notification from the television 10 by. The user may manually start the remote control application after confirming that the color of the remote control application has changed.

As described above, according to the present embodiment, for example, connection of the video camera 30 to the television 10 is used as a trigger to establish cooperation among the video camera 30 , the television 10 , and the smartphone 20 . The video camera 30 and the television 10 can be cooperatively controlled by remote control operation from the smartphone 20 .

As described above, according to the present embodiment, even in an environment in which a wide variety of external devices (video cameras) may be connected to a video display device (television), not only a specific external device, automatic It is possible to establish cooperation between devices in a practical manner. Therefore, a three-party cooperation system with good operability and usability can be established without imposing an excessive burden on the user.

<Second embodiment>
Next, a second embodiment of the invention will be described. In the first embodiment, the video display device, the external device, and the remote control terminal perform three-party cooperation processing by the video display device functioning as a relay device. In this embodiment, the remote control terminal takes the lead and implements the cooperation.

That is, in the first embodiment, the television 10 is positioned centrally and plays the role of controlling the entire system. On the other hand, in the second embodiment, smartphone 20 controls the entire system.

FIG. 12 shows a configuration diagram of the three-party collaboration system of this embodiment. As shown in the figure, the three-party collaboration system of this embodiment includes a video display device (television) 10, a remote control terminal (smartphone) 20, an external device (video camera) 30, and an access point 40. Prepare.

The basic configurations of the television 10, smartphone 20, and video camera 30 of this embodiment are the same as those of the first embodiment. Also, the access point 40 connects wireless LAN client devices such as the television 10, the smartphone 20, and the video camera 30 to each other,
Also, these wireless LAN clients are connected to other networks.

The present embodiment will be described below, focusing on the configuration different from that of the first embodiment. Hereinafter, unless otherwise specified, parts common to those of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, the television 10, the smartphone 20, and the video camera 30 are connected via an access point 40 via a wireless LAN, for example. That is, they do not make HDMI connections. Therefore, the television 10 and the video camera 30 do not have to have the HDMI communication I/F 15 and the HDMI communication I/F 35 .

[Function configuration]
[Video camera]
The video camera 30 of this embodiment has an access point 40 as shown in FIG.
a connection request transmission unit 310 for transmitting a connection request to all the devices in the same subnetwork of the wireless LAN via . In this embodiment, the connection request is, for example, the device I
including D. Note that the devices to which the connection request is sent may be limited to the television 10 and the smartphone 20 . A connection request is transmitted via the wireless LAN communication I/F 37 .

The above functions realized by the video camera 30 are realized by the microprocessor of the control unit 31 developing a program stored in the storage area of the storage unit 34 into a program area and executing the program. All or part of the functions realized by the video camera 30 may be realized by hardware such as ASIC and FPGA.

[smartphone]
As shown in FIG. 13(b), the smartphone 20 of the present embodiment includes a second cooperation establishing unit 21
0a, and a remote control processing unit 220a.

Upon receiving a connection request from the video camera 30 via the wireless LAN communication I/F 27, the second cooperation establishing unit 210a activates the remote control applications of the video camera 30 and the television 10, respectively. Therefore, the second cooperation establishment unit 210a includes a cooperation table creation unit 211a, a remote controller determination unit 212, and a display destination determination unit 213.

The linkage table creating unit 211a creates a linkage table 800 by pairing the devices to be linked. Pairing is performed using, for example, short-range wireless communication. for example,
There is no particular limitation as long as known means such as performing mutually designated button operations between devices brought close to each other may be used. Further, for example, the smartphone 20 may be configured to access the access point 40 and select the television 10 and the video camera 30 from the obtained list of connected devices. As a result, the type of device and the device ID that identifies the device can be obtained. The device type is information that can specify a video display device, an image storage device, or the like, and the device ID is, for example, an IP address.

The linkage table creation unit 211a creates a device ID for the list of devices obtained by pairing.
Based on D (IP address), the server 90 or the like is accessed, and information (for example, remote control application name) of the remote control application of the device is obtained. The obtained information is correlated to create a link table 800 as shown in FIG.

In addition, when acquiring the information of the remote control application, the smartphone 20 also determines whether or not cooperation is possible. For example, a remote control application for the OS of the smartphone 20 may not be prepared. A device for which only such a remote control application is prepared is determined to be incapable of cooperation and is not registered in the cooperation table 800 .

The created linkage table 800 contains a device ID 810, information (type) 820 for identifying the type of the device, information (remote control application name) 830 of the remote control application of the device,

FIG. 14 exemplifies a case where "1" is registered as the installation 840 when the remote control application is installed, and "0" is registered when it is not installed. The cooperation table 800 of this embodiment is registered in the storage unit 24 of the smartphone 20 .

Upon receiving a connection request from the video camera 30, the remote controller determination unit 212 performs remote controller determination processing to determine the smartphone 20 to be the remote controller among all smartphones connected to the same subnetwork.

Specifically, it determines whether or not the device ID included in the connection request is registered in the linkage table 800 held by itself, and if not, ends the process. On the other hand, if registered, the smart phone itself is set as a candidate smart phone that can be used as a remote controller. Then, it is determined whether or not there is another smartphone that is similarly set as a candidate smartphone within the same subnetwork.

At this time, if there are no other candidate smart phones, the smart phone 20 itself is determined to be used as a remote controller. On the other hand, if there are other candidate smartphones, the candidate smartphones communicate with each other to determine which smartphone 20 is to be used as the remote controller. Here, for example, a distributed arbitration technique is used for determination.

As for the method of selecting the smartphone 20 to be used as a remote controller, it is possible to determine the order of priority among the smartphones in advance, select the candidate smartphone with the highest priority, select the candidate smartphone closest to the video camera 30, or the like. be. The distance between the video camera 30 and the smartphone 20 is calculated by specifying the installation location of the video camera 30 and estimating the position of the smartphone 20 from the access point 40 based on the radio wave intensity of GPS or wireless LAN.

Note that if communication with the smartphone 20 selected as the remote controller is disconnected after the start of the three-party cooperation process, the video camera 30 requests connection again. At this time, the remote controller determination unit 212 receives the connection request, performs remote controller determination processing, and performs reselection by determining the smartphone 20 to be used as the remote controller.

Further, when the display destination determining unit 213 (to be described later) determines the television 10 on which to display the video, the remote controller determining unit 212 of the present embodiment adds remote control applications for the video camera 30 and the television 10 to be used for the three-way linkage to the linkage table 800. Determine if is installed. After the determination, the remote control application is obtained and installed as necessary.

When the smart phone 20 used as the remote controller is determined, the display destination determination unit 213 determines the television 10 as the display destination (display destination device) of the image of the video camera 30 among the televisions in the same subnetwork.

Televisions within the same subnetwork and registered in the linkage table 800 (
If there are a plurality of candidate televisions, one of them is selected as the television 10 of the display destination device. For the selection of the television 10 as the display destination device, for example, the priority among the candidate televisions is determined in advance,
A method of selecting the television with the highest priority, a method of setting the candidate television closest to the smartphone 20 to the display destination device television 10, a method of setting the candidate television closest to the video camera 30 to the display destination device television 10, or a plurality of methods. a method of displaying a list of candidate televisions for the user and allowing the user to make a selection.

Note that when selecting the candidate television closest to the smartphone 20, for example, short-range wireless communication is performed between each candidate television and the smartphone 20, and the candidate television with the highest radio wave intensity at that time is the closest to the smartphone 20. Let TV be a candidate. video camera 3
When selecting the candidate television closest to 0, for example, the video camera 30 and each candidate television acquire position information using a GPS function (not shown) or the like for the video camera 30 and each candidate television, and each acquired position From the information, the distance between the video camera 30 and each candidate television is detected, and the closest candidate television is determined.

The remote control processing unit 220a executes three-party cooperation processing among the own smartphone 20, the television 10 serving as a display destination device, and the video camera 30.

, the first cooperation establishing unit 120 and the relay table 500 may not be provided.
Further, instead of the relay unit 130, a relay unit 130a is provided.

The relay unit 130a of the present embodiment receives, from the smartphone 20, a device ID that specifies a data transmission source and an operation instruction for the data. Also, when data is received from the video camera 30 having the received device ID, the data is processed according to the received operation instruction. The received operation instruction is, for example, to display the data on the display unit 13, to store the data in the storage unit 14, or the like. Also, when the process is finished, the smart phone 20 is notified to that effect.
Note that the device ID, operation instructions, and data are received via the wireless LAN communication I/F 17 .

[Three-Party Coordination Processing Flow]
By the television 10, the smartphone 20 and the video camera 30 having the above functions,
A flow of three-party collaboration processing according to the present embodiment will be described. FIG. 15 is a flowchart for explaining the flow of the three-party cooperation processing of this embodiment. It is assumed that the cooperation table 800 is created in advance.

Here, as in the first embodiment, a desired moving image is selected from the moving images recorded in the storage unit 34 of the video camera 30 by operating the smartphone 20 and displayed on the display unit 13 of the television 10. A case will be described as an example. Other remote control operations, such as
Any normal remote control operation of the video camera 30 and the television 10, such as an operation of storing a moving image or a still image held by the video camera 30 in the storage unit 14 of the television 10, is not particularly limited to this example.

First, the connection request transmission unit 310 of the video camera 30, via the access point 40,
A connection request is transmitted (step S321). The connection request is sent to all smartphones within the same subnetwork.

Upon receiving the connection request from the video camera 30, the remote controller determination units 212 of all smartphones in the same subnetwork perform remote controller determination processing, and determine the smartphone 20 to be the remote controller in this three-party cooperation processing (step S221). Decisions are made in the manner described above.

After that, the display destination determination unit 213 of the smartphone 20 determined in step S221 determines the television 10 as the display destination device from among all the televisions in the same subnetwork (step S222).

Then, the remote controller determining unit 212 acquires a remote controller application (step S223).
The flow of the remote control application acquisition process is substantially the same as the remote control application acquisition process described in FIG. 10 of the first embodiment. However, in this embodiment, the television 10 and the video camera 30
This processing is executed for each.

That is, the notified device ID of the video camera 30 and the determined device I of the television 10
D is used to search the linkage table 800 to determine whether or not a remote control application has been installed in association with each device ID. And if installed,
Determine whether the version of the app is the latest version. And if the remote control app is not installed, or if it is installed but not the latest version,
Download the latest version of the remote control app from a compatible server and install it.

After completing the remote control application acquisition process, the remote control processing unit 220a of the smartphone 20 activates each remote control application and displays a remote control image on the touch panel 23 of the smartphone 20 (step S224).

After that, the remote control processing unit 220a instructs to transfer the moving image selection screen of the video camera 30 (step S225). This transfer instruction is transmitted from smartphone 20 to television 10 and video camera 30 via access point 40 . Note that the transfer instruction includes identification information (for example, I
P address).

Then, the video camera 30 that has received it transfers the data of the moving image selection screen to the television 10 that is the display destination device (step S322). Note that the moving image selection screen is, for example, a screen for selecting moving images stored in the video camera 30, as in the first embodiment. The screen to be selected is, for example, an image displaying a thumbnail image of a moving image.

The relay unit 130a of the television 10 that has received the data of the moving image selection screen displays the moving image selection screen of the video camera 30 on the display unit 13 according to the data (step S121). Then, the smartphone 20 that is the transmission source is notified that the screen display has ended (step S122).

Upon receiving the screen display end notification, the remote control processing unit 220a of the smartphone 20
Make it possible to accept remote control operations from the user. This allows the user to give instructions to the video camera 30 while watching the moving image selection screen displayed on the display unit 13 of the television 10 .

Upon receiving an operation instruction from the user, remote control processing unit 220a transmits the instruction to television 10 and video camera 30 (step S226). The operation instruction received here is, for example, an instruction to reproduce the selected moving image. The moving image is selected, for example, from thumbnail images of moving images displayed as a moving image selection screen on the television 10 .

Upon receiving the instruction, the video camera 30 transfers the data to the television 10 according to the operation instruction (step S323). For example, when an instruction to reproduce a predetermined moving image is received, the moving image data is transferred to the television 10 .

The relay unit 130a of the television 10 displays the transferred data on the display unit 13 (step S123), and transmits a process end notification indicating that the display process has ended to the smartphone 20 (step S124). For example, when moving image data is received, display of the moving image is started.

The remote control processing unit 220a of the smartphone 20 that has received the processing end notification updates the remote control image (step S227).

As described above, according to the present embodiment, when the video camera 30 issues a connection request via the access point 40, the television 10 as the display destination and the smartphone 20 used as the remote controller are automatically determined, and Three-party cooperation processing is executed between That is, the user can operate the video camera 30 and the television 10 by operating the smartphone 20 , and can display the video data held in the video camera 30 on the television 10 .

As described above, according to the present embodiment, it is possible to realize a three-party cooperation system with good operability with a small burden, as in the first embodiment.

In the above-described second embodiment, the video camera 30 is configured to start the three-party cooperation processing using the transmission of a connection request to the smartphone 20 in the same subnetwork via the access point 40 as a trigger. but not limited to.

For example, the installation of the video camera 30 on the charging dock may be used as a trigger to start the three-party cooperation process. The charging dock is capable of, for example, contactless charging or charging from a power outlet, and contactless charging or charging from a power outlet is selected depending on the support status of the installed video camera 30 . Furthermore, the charging dock is configured to be able to notify the video camera 30 of the charging dock device ID by short-range communication (NFC, IR communication, Bluetooth, etc.).

In this case, when the video camera 30 is placed on the charging dock, for example, contactless charging is started and the video camera 30 receives the ID of the charging dock through NFC communication.
Then, the video camera 30 transmits its own device ID and the device ID of the charging dock as triggers to all the devices within the same subnetwork of the wireless LAN.

As a result, simply by installing the video camera 30 in the charging dock, the three-party cooperation process is executed. That is, the user can control the video camera 30 and the television 10 using the predetermined smartphone 20 simply by placing the video camera 30 on the charging dock.

Further, in the second embodiment, the type and remote control application are registered in the linkage table 800 for each device, but the present invention is not limited to this. For example, when a remote control application is obtained for each combination of a television and a video camera, the linkage table may have the same configuration as the first embodiment.

That is, the link table creating unit 211a accesses the server 90 and extracts, for each candidate TV, a video camera having a remote control application that can be operated in cooperation with the candidate TV. Then, the obtained video camera is registered as a candidate video camera together with the information of the remote control application.

In this case, as in the first embodiment, the remote control processing unit 220a develops the remote control application held in the link table in association with the video camera 30 and the determined television 10, and executes remote control processing.

Further, in each of the above-described embodiments, if the smartphone 20 does not have the remote control application, it is automatically downloaded from the server via the Internet and installed. However, it is not limited to this method. For example, a prompt may be displayed on the touch panel 23 of the smartphone 20 to prompt the user to download the remote control application, and the download and installation may be performed after the user's instruction is received. The same applies to downloading and installing the relay application of the television 10 of the first embodiment.

Examples of embodiments of the present invention have been described above. Needless to say, the configuration for realizing the technology of the present invention is not limited to the above-described embodiment, and various modifications are conceivable. Numerical values appearing in the text and figures are only examples, and the effect of the present invention is not impaired even if different values are used.

Some or all of the above-described functions and the like of the present invention may be realized by hardware by designing them in an integrated circuit, for example. Alternatively, the functions may be realized by software, in which the microprocessor unit or the like interprets and executes a program for realizing each function. Hardware and software may be used together.
