Next, with reference to FIG. 4, a sequence when the user operates the mobile phone 200 and operates the digital camera 100 by remote control will be described. FIG. 4 is a sequence diagram of a communication system including a digital camera 100 and a mobile phone 200.
As described above, Bluetooth Low Energy (BLE) is used for communication between the mobile phone 200 and the digital camera 100. In BLE communication, communication is performed every time the time represented by the connection interval elapses. For example, when it is desired to transmit some information from the mobile phone 200 to the digital camera 100, it is transmitted at the time of communication at each connection interval. Even if the information to be transmitted to the digital camera 100 is generated while waiting for the elapse of the connection interval on the mobile phone 200, the information is not transmitted immediately, but the communication timing for each connection interval. Will be sent by. The same applies to transmission from the digital camera 100 to the mobile phone 200. Even if there is no information to be transmitted, communication is performed at each connection interval. Under this premise, the communication between the mobile phone 200 and the digital camera 100 will be described below.

In step S401, the user performs an operation for starting the remote control operation by using the operation unit 205 of the mobile phone 200. The mobile phone 200 accepts the operation of starting the remote control operation.
In the following step S402, the mobile phone 200 transmits a remote control operation start request to the digital camera 100. As described above, this transmission is transmitted at the timing of communication due to the passage of the connection interval. In FIG. 4, the timing of step S402 is the timing of communication due to the passage of the connection interval. The digital camera 100 receives the remote control operation start request.
In step S403, when the digital camera 100 determines that the remote control operation start request can be accepted, it transmits a permission notification to the mobile phone 200 as a response to the remote control operation start request. This transmission is performed after the connection interval has elapsed from the data communication performed in step S401. The digital camera 100 receives the response of the remote control operation start request. The connection interval here is T_slow.

After transmitting the response of the remote control operation start request, the digital camera 100 determines whether or not the connection interval T_slow is long. A more specific determination method will be described in step S501 of FIG. When it is determined that T_slow is long, in step S404, the digital camera 100 transmits a request for changing the connection interval to the mobile phone 200. The mobile phone 200 receives a request for changing the connection interval.
The mobile phone 200 confirms whether or not the connection interval can be changed to the time specified in the connection interval change request. Then, in step S405, the mobile phone 200 transmits a connection interval change notification to the digital camera 100. The connection interval change notification includes information about the changed connection interval and the timing of changing the connection interval. In the example of FIG. 4, it is assumed that the connection interval after the change is T_fast, and the timing for changing the connection interval is step S411. In step S411, the process of the control unit 201 of the mobile phone 200 for changing the connection interval is an example of the process by the changing means.

Next, an example of an operation in which the user operates the operation unit 205 of the mobile phone 200 to operate the digital camera 100 before the timing when the connection interval is changed will be described.
In step S406, the user presses the button displayed on the display unit 206 of the mobile phone 200 by using the operation unit 205 of the mobile phone 200. The user pressing a button is an example of starting a predetermined operation.
In step S407, the user releases the button pressed in step S406 by using the operation unit 205 of the mobile phone 200. The user releasing the button is an example of the end of a predetermined operation. Step S407 shall be performed within the T_slow_wait time from step S406, and T_slow_wait shall be shorter than T_slow (T_slow> T_slow_wait). Further, the T_slow_wait time is different from the connection intervals such as T_slow and T_fast that are always counted, and the counting is started according to the reception of the button pressing operation.
In step S408, the mobile phone 200 transmits the operation information to the digital camera 100. The operation information here includes information that can identify the button operated by the user, information indicating that the user has pressed the button, and information indicating that the button has been released. The digital camera 100 receives the operation information.

In step S409, the digital camera 100 separates the received operation information into information indicating that the user has pressed the button and information indicating that the user has released the button. Then, the digital camera 100 performs a process corresponding to the user pressing the button with respect to the button pressed by the user in step S406.
In step S410, the digital camera 100 performs a process corresponding to the user releasing the button for the button released by the user in step S407 after the lapse of the time represented by T_button counted from the process of step S409. .. T_button is shorter than the key repeat time (T_keyrepeat) described later.
The processing performed in steps S409 and S410 is, in principle, the same processing as the processing when the button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user is pressed or released. However, when there is no button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user, the processing performed in steps S409 and S410 is the processing corresponding to the button peculiar to the mobile phone 200 operated by the user. ..

As an example of the button peculiar to the mobile phone 200, there is a slide show button 315 of the playback remote control screen 310 of FIG. 3B. For example, when the slide show button 315 of the mobile phone 200 is pressed and released, the digital camera 100 starts the slide show on the display unit 106.
In the above description, an example in which the timing at which steps S406 and S407 are performed is between steps S405 and S408 has been described, but this timing is an example. For example, it is conceivable that steps S406 and S407 are performed between steps S403 and S404. In this case, at the timing of step S404, the operation information (including information indicating that the user has pressed the button and released the button) transmitted in step S408 is transmitted from the mobile phone 200 to the digital camera 100. You will be notified. The fact that the process of step S408 is the timing of step S404 does not affect the transmission of the connection interval change request from the digital camera 100. In the communication performed at each connection interval, information can be transmitted to each other at the same time.

Next, an example of an operation in which the user operates the operation unit 205 of the mobile phone 200 to operate the digital camera 100 after the timing when the connection interval is changed will be described.
In step S411, the digital camera 100 and the mobile phone 200 change the connection interval from T_slow to T_fast at the same time at the timing specified in step S405. T_fast is shorter than the key repeat time (T_keyrepeat) described later.
In step S412, the user presses the button displayed on the display unit 206 of the mobile phone 200 by using the operation unit 205 of the mobile phone 200.
In step S413, the mobile phone 200 transmits the operation information to the digital camera 100. The operation information here includes information that can identify the button operated by the user and information indicating that the user has pressed the button. The digital camera 100 receives the operation information.
In step S414, the digital camera 100 performs a process corresponding to the user pressing the button with respect to the button pressed by the user in step S412.
From step S413 to S416, every time T_fast elapses, the mobile phone 200 repeatedly notifies the digital camera 100 that the button operated in step S412 is being pressed.

In step S415, the user releases the button pressed in step S412 by using the operation unit 205 of the mobile phone 200.
In step S416, the mobile phone 200 transmits the operation information to the digital camera 100. The operation information here includes information that can identify the button operated by the user and information that indicates that the button has been released. The digital camera 100 receives the operation information.
In step S417, the digital camera 100 performs a process corresponding to the user releasing the button with respect to the button released by the user in step S415.
The processing performed in steps S414 and S417 is the same as the processing performed in steps S409 and S410.
After step S415, if the user does not operate the button, the mobile phone 200 repeatedly notifies the digital camera 100 of information indicating that the button has not been operated each time T_fast elapses. The information indicating that the button is not operated here is, in other words, information indicating that the button is still in the released state.

Here, the conditions for suppressing the occurrence of key repeat in the digital camera 100 contrary to the intention of the user will be described. The key repeat is that when the user holds down the button and does not release it, the digital camera 100 repeatedly executes a process corresponding to the user pressing the button every key repeat time (T_keyrepeat). The key repeat time is an example of the repeat time of the present invention.
In order to suppress the occurrence of key repeat in the digital camera 100 contrary to the intention of the user, it is necessary to satisfy the following first condition or second condition.

The first condition is "T_slow>T_keyrepeat>T_button". That is, the first condition is that T_slow is longer than the key repeat time and the key repeat time is longer than T_button.
The first condition is satisfied during the operation of the user in steps S406 and S407. Therefore, it is possible to suppress the occurrence of key repeat in the digital camera 100 contrary to the intention of the user.
The second condition is "T_keyrepeat>T_fast". That is, the second condition is that the key repeat time is longer than T_fast.
The second condition is satisfied during the operation of the user in steps S412 and S415. Therefore, it is possible to suppress the occurrence of key repeat in the digital camera 100 contrary to the intention of the user.

In the sequence of FIG. 4, the format of the data transmitted from the mobile phone 200 to the digital camera 100 is a format such as "write command" that allows the next data to be transmitted without a response from the digital camera 100. However, the format of the data transmitted from the mobile phone 200 to the digital camera 100 may be a format that requires a response from the digital camera 100, such as "write with response". At this time, the time interval when the operation information is transmitted from the mobile phone 200 to the digital camera 100 is "connection interval (T_slow or T_fast) x 2". Then, in order to suppress the occurrence of key repeat in the digital camera 100 contrary to the intention of the user, it is necessary to satisfy the following third condition or fourth condition.

The third condition is "T_slow x 2>T_keyrepeat>T_button". That is, the first condition is that twice T_slow is larger than the key repeat time and the key repeat time is larger than T_button. The third condition corresponds to the first condition described above.
The fourth condition is "T_keyrepeat> T_fast x 2". That is, the second condition is that the key repeat time is larger than twice T_fast. The fourth condition corresponds to the second condition described above.
That is, the condition for suppressing the occurrence of key repeat in the digital camera 100 against the intention of the user depends on the time interval when the operation information is transmitted from the mobile phone 200 to the digital camera 100.

In the sequence of FIG. 4, the key repeat time is constant. However, each button pressed by the user, each screen of the mobile phone 200 operated by the user shown in FIGS. 3A to 3C, or the screen of the digital camera 100 shown in FIGS. 3D to 3F. It is possible that the key repeat time will be different for each. At this time, the digital camera 100 and the mobile phone 200 set the shortest key repeat time as the key repeat time of the above conditions 1 to 4.
When the remote control operation is completed or the power is turned off, the connection interval is lengthened again in order to reduce power consumption.

Next, with reference to FIG. 5, the processing of the digital camera 100 when the remote control operation is performed will be described. FIG. 5 is a flowchart of the digital camera 100 when operating the remote controller. The processing of the flowchart of FIG. 5 is realized by the control unit 101 of the digital camera 100 controlling each unit of the digital camera 100 according to an input signal or a program. Further, the processing of the flowchart of FIG. 5 is started in response to receiving the remote control operation start request from the device connected to the digital camera 100.

In step S501, the control unit 101 determines whether or not the connection interval used by the proximity wireless communication unit 112 is long for performing the remote control operation. The control unit 101 determines, for example, as follows.
First, the control unit 101 determines the time interval during which the mobile phone 200 can transmit the operation information based on the connection interval. This time interval is the time interval between the time when the mobile phone 200 transmits the operation information to the digital camera 100 and the time when the mobile phone 200 next transmits the operation information to the digital camera 100. For example, when the format of the data transmitted from the mobile phone 200 to the digital camera 100 is such that the next data can be transmitted without a response from the digital camera 100, the time interval during which the operation information can be transmitted is equal to the connection interval. Further, when the format of the data transmitted from the mobile phone 200 to the digital camera 100 is such that the next data can be transmitted after receiving the response from the digital camera 100, the time interval during which the operation information can be transmitted is equal to twice the connection interval. The process of determining the time interval is an example of the process by the determining means.
Next, the control unit 101 determines whether or not the determined time interval is equal to or longer than the key repeat time. Determining that the time interval determined by the control unit 101 is equal to or longer than the key repeat time is equivalent to determining that the connection interval used by the control unit 101 in the proximity wireless communication unit 112 is long for remote control operation. Further, determining that the time interval determined by the control unit 101 is smaller than the key repeat time determines that the connection interval used by the control unit 101 in the proximity wireless communication unit 112 is not long for remote control operation. be equivalent to.
When the control unit 101 determines that the connection interval used by the proximity wireless communication unit 112 is long for performing the remote control operation, the process proceeds to step S502. When the control unit 101 determines that the connection interval used by the proximity wireless communication unit 112 is not long for performing the remote control operation, the process proceeds to step S505.

In step S502, the control unit 101 transmits a connection interval change request to the mobile phone 200 via the proximity wireless communication unit 112. The connection interval specified by the control unit 101 specified in this change request is such that the above-mentioned time interval determined by the control unit 101 is smaller than the key repeat time. Note that step S502 is an example of processing by the notification means.
In step S503, the control unit 101 determines whether or not the already received remote control operation start request is a start request for the remote control operation for shooting. When the control unit 101 determines that the remote control operation start request is the start request for the remote control operation for shooting, the process proceeds to step S504. When the control unit 101 determines that the remote control operation start request is not the start request for the remote control operation for shooting, the process proceeds to step S505.
In step S504, the control unit 101 controls the display unit 106 to cause the display unit 106 to display the shooting screen 350 including the pop-up 351 as shown in FIG. 3 (f). Pop-up 351 represents a warning to the user that the timing of shooting may be delayed. In the example of FIG. 3 (f), the pop-up 351 is a notification including a message, but the pop-up 351 may be an icon or the like. Note that step S504 is an example of processing by the warning means.

In step S505, the control unit 101 determines whether or not a remote control operation end request has been received from the mobile phone 200 via the proximity wireless communication unit 112. When the control unit 101 determines that the remote control operation end request has been received, the control unit 101 ends the process shown in FIG. 5, so that the remote control operation cannot be performed. When the control unit 101 determines that the remote control operation end request has not been received, the process proceeds to step S506.
In step S506, the control unit 101 includes the operation information received via the proximity wireless communication unit 112 including the information indicating that the user has pressed the button and does not include the information indicating that the user has released the button. Judge whether or not. When the control unit 101 determines that the operation information includes information indicating that the user has pressed the button and does not include information indicating that the user has released the button, the process proceeds to step S507. When the control unit 101 determines that the operation information does not include the information indicating that the user has pressed the button or contains the information indicating that the user has released the button, the process proceeds to step S508. The process of receiving the operation information via the proximity wireless communication unit 112 is an example of the process by the receiving means.
In step S507, the control unit 101 performs a process corresponding to the user pressing a button. The process performed in step S507 is, in principle, the same process as the process when the button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user is pressed. However, when there is no button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user, the process performed in step S507 is the process corresponding to the button peculiar to the mobile phone 200 operated by the user. The process of step S507 is an example of the process by the second processing means.

In step S508, the control unit 101 includes the information indicating that the user has released the button, and does not include the information indicating that the user has pressed the button, in the operation information received via the proximity wireless communication unit 112. Judge whether or not. When the control unit 101 determines that the operation information includes information indicating that the user has released the button and does not include information indicating that the user has pressed the button, the process proceeds to step S509. When the control unit 101 determines that the operation information does not include information indicating that the user has released the button, or includes information indicating that the user has pressed the button, the process proceeds to step S510. The process performed in step S509 when the process proceeds from step S508 to step S509 is an example of the process by the third processing means.
In step S509, the control unit 101 performs a process corresponding to the user releasing the button. The process performed in step S509 is, in principle, the same process as the process when the button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user is released. However, when there is no button of the digital camera 100 corresponding to the button of the mobile phone 200 operated by the user, the process performed in step S509 is the process corresponding to the button peculiar to the mobile phone 200 operated by the user.

In step S510, whether or not the operation information received via the proximity wireless communication unit 112 includes information indicating that the user has pressed the button and information indicating that the user has released the button. To judge. When the control unit 101 determines that the operation information includes information indicating that the user has pressed the button and information indicating that the user has released the button, the process proceeds to step S511. When the control unit 101 determines that the operation information does not include the information indicating that the user has pressed the button or the information indicating that the user has released the button, the process returns to step S505. The processing performed in steps S511, S512 and S509 when the processing proceeds from step S510 to step S511 is an example of processing by the first processing means.
In step S511, the control unit 101 performs a process corresponding to the user pressing a button. The process of step S511 is the same as that of step S509.
In step S512, the control unit 101 waits for a predetermined waiting time. This waiting time is the time represented by T_button described in FIG. 4, and is smaller than the key repeat time. After that, the process proceeds to step S509.

Here, it will be described that the first and second conditions described with reference to FIG. 4 are satisfied by the processing of FIG.
The first and second conditions are that when the format of the data transmitted from the mobile phone 200 to the digital camera 100 is such that the next data can be transmitted without a response from the digital camera 100, a key repeat contrary to the user's intention occurs. It is a condition that can suppress this. In this case, as described above, the time interval determined by the control unit 101 is equal to the connection interval. Further, T_button, which is the time interval between steps S409 and S410 in FIG. 4, is equal to the time to wait in step S512 in FIG. Therefore, when it is determined in step S501 that the connection interval is long, the first condition "T_slow>T_keyrepeat>T_button" is satisfied until the request for changing the connection interval made in step S502 is reflected.
Further, when the request for changing the connection interval made in step S502 is reflected, the connection interval becomes smaller than the key repeat time. Therefore, the second condition "T_keyrepeat>T_fast" is satisfied.

Next, it will be described that the processing of FIG. 5 satisfies the third and fourth conditions described with reference to FIG.
The third and fourth conditions are that a key repeat contrary to the user's intention occurs when the format of the data transmitted from the mobile phone 200 to the digital camera 100 is a format that requires a response from the digital camera 100. It is a condition that can suppress. In this case, as described above, the time interval determined by the control unit 101 is equal to twice the connection interval. Further, T_button, which is the time interval between steps S409 and S410 in FIG. 4, is equal to the time to wait in step S512 in FIG. Therefore, when it is determined in step S501 that the connection interval is long, the third condition "T_slow × 2>T_keyrepeat>T_button" is satisfied until the request for changing the connection interval made in step S502 is reflected.
Further, when the request for changing the connection interval made in step S502 is reflected, twice the connection interval becomes smaller than the key repeat time. Therefore, the fourth condition "T_keyrepeat> T_fast x 2" is satisfied.

In the process described with reference to FIG. 5, when the remote control operation for shooting is requested, the warning represented by the pop-up 351 is issued in step S504. However, the timing of issuing a warning may be changed according to the object to be photographed, the mode of photography, and the like. For example, a warning may be issued only when the shooting timing is assumed to be severe, such as when the AF mode is changed to continuous AF or when the recognized person moves violently. As a result, when the shooting timing is not so severe, such as when shooting a still life, it is possible to avoid the annoyance of unnecessary warnings by not issuing a warning to the user.
Further, in the process described with reference to FIG. 5, a warning represented by a pop-up 351 as shown in FIG. 3 (f) is issued in step S504 at the time of remote control operation for shooting. However, as a warning, a mark, an icon, or the like may be displayed instead of the pop-up 351. Further, the mark, the icon, or the like may be hidden at the timing when the connection interval is changed. This allows the user to explicitly know when there is a delay in button operation.

Further, in the process described with reference to FIG. 5, a warning is issued by the digital camera 100 in step S504. However, if it is determined in step S501 that the connection interval is long, the digital camera 100 may send a predetermined notification to the mobile phone 200, and the mobile phone 200 may issue a warning to the user. At this time, when the user performs a predetermined operation, after a predetermined time elapses, or when the connection interval becomes equal to or less than a predetermined value, the digital camera 100 transmits a predetermined notification to the mobile phone 200, and the mobile phone 200 You may hide the warning. As a result, the user can explicitly know when there is a delay in button operation while operating the remote controller.
Further, in the process described with reference to FIG. 5, the digital camera 100 first receives a request for starting a remote control operation for shooting or playback from the mobile phone 200 and operates. However, the state may be automatically switched to a state in which the remote control operation for shooting and playback can be performed according to the operation mode of the digital camera 100. At this time, the user may be able to perform the remote control operation for reproduction during the remote control operation for shooting, or to operate the remote control for shooting during the remote control operation for reproduction, if necessary. As a result, it is possible to reduce the troublesomeness of selecting the operation mode of the digital camera 100 when operating the remote controller.

Next, with reference to FIG. 6, the processing of the mobile phone 200 when the remote control operation is performed will be described. FIG. 6 is a flowchart of the mobile phone 200 when operating the remote controller. The processing of the flowchart of FIG. 6 is realized by the control unit 201 of the mobile phone 200 controlling each unit of the mobile phone 200 according to an input signal or a program. Further, the processing of the flowchart of FIG. 6 is started in response to the mobile phone 200 receiving the remote control operation start request from the operator of the mobile phone 200 and the mobile phone 200 transmitting the remote control operation start request to the connected device. Will be done. In the description of FIG. 6, the digital camera 100 is taken as an example of the connected device of the mobile phone 200, but a device other than the digital camera 100 may be used.

In step S601, the control unit 201 waits for reception of a response to the remote control operation start request. When the control unit 201 determines that the response has been received, the process proceeds to step S602, and when the control unit 201 determines that the response has not been received, step S601 is processed again.
In step S602, the control unit 201 determines whether or not the start of the remote control operation is permitted based on the received response. When the control unit 201 determines that the start of the remote control operation is permitted, the process proceeds to step S603. When the control unit 201 determines that the start of the remote control operation is not permitted, the process proceeds to step S612.

In step S603, the control unit 201 determines whether or not the button of the operation unit 205 has been pressed. When the control unit 201 determines that the button has been pressed, the process proceeds to step S604. When the control unit 201 determines that the button has not been pressed, the process proceeds to step S607. The button may be a button displayed by the display unit 206 on the touch panel of the operation unit 205, or may be a push button or the like provided on the operation unit 205.
In step S604, the control unit 201 determines whether or not the same button as the button pressed in step S603 is released during the connection interval after the button is pressed in step S603. When the control unit 201 determines that the same button has been released, the process proceeds to step S605. When the control unit 201 determines that the same button has not been released, the process proceeds to step S606.
Note that step S604 described here is a process when the format of the data transmitted from the mobile phone 200 to the digital camera 100 is a format in which the next data can be transmitted without a response from the digital camera 100. When the format of the data transmitted from the mobile phone 200 to the digital camera 100 is a format that requires a response from the digital camera 100, in step S604, the control unit 201 makes the following determination. That is, the control unit 201 determines whether or not the same button as the button pressed in step S603 is released within a time twice the connection interval after the button is pressed in step S603.
That is, in step S604, after the button is pressed in step S603, whether or not the same button as the button pressed in step S603 is released during the time interval during which the mobile phone 200 can transmit the operation information. To judge.

In step S605, the control unit 201 generates operation information including information that can identify the button operated by the user, information indicating that the user has pressed the button, and information indicating that the user has released the same button. To do. Then, the control unit 201 transmits to the digital camera 100 via the communication unit 211. After that, the process returns to step S603. Note that step S605 is an example of processing by the first transmission means.
In step S606, the control unit 201 generates operation information including information that can identify the button operated by the user and information indicating that the user has pressed the button, and the digital camera via the communication unit 211 generates operation information. Send to 100. After that, the process returns to step S603. Note that step S606 is an example of processing by the second transmission means.

In step S607, the control unit 201 determines whether or not the button of the operation unit 205 has been released. When the control unit 201 determines that the button has been released, the process proceeds to step S608. When the control unit 201 determines that the button has not been released, the process proceeds to step S609. In step S607, it is determined that the button of the operation unit 205 is released by the control unit 201 because the button of the operation unit 205 is released after the time interval in which the mobile phone 200 can transmit the operation information elapses after the button is pressed. If it is done.
In steps S603, S604, and S607, the process of determining whether or not the button of the operation unit 205 has been pressed or released is an example of the process by the receiving means that accepts a predetermined operation. In each step, when it is determined by the operation unit 205 that the button has been pressed or released, it corresponds to the acceptance of the operation on the button.
In step S608, the control unit 201 generates operation information including information that can identify the button operated by the user and information indicating that the user has released the button, and the digital camera via the communication unit 211 generates operation information. Send to 100. After that, the process returns to step S603. Note that step S608 is an example of processing by the third transmission means.

In step S609, the control unit 201 determines whether or not a request for changing the connection interval has been received from the digital camera 100 via the communication unit 211. When the control unit 201 determines that the connection interval change request has been received, the process proceeds to step S610, and when the control unit 201 determines that the connection interval change request has not been received, the process proceeds to step S611.
In step S610, the control unit 201 determines the connection interval corresponding to the request and the timing at which the connection interval is actually changed, taking into consideration the system restrictions (time range, etc.) of the mobile phone 200. Then, the control unit 201 transmits a change notification of the connection interval to the digital camera 100 via the communication unit 211. The connection interval change notification includes information on the determined connection interval and the timing at which the connection interval is actually changed.

In step S611, the control unit 201 determines whether or not the operation unit 205 has performed an operation for terminating the remote control operation. When the control unit 201 determines that the operation for ending the remote control operation has been performed, the process of FIG. 6 ends. When the control unit 201 determines that the operation for ending the remote control operation has not been performed, the process returns to step S603.
In step S612, the control unit 201 displays an error screen on the display unit 206 to notify the user that the remote control operation is not permitted.

In the process described with reference to FIG. 6, after the button press is detected in step S603, it is determined whether or not the next button operation is performed during the connection interval. However, when the operation unit 205 can detect the release of the same button, a process of accepting the operation of another button may be performed.

[effect]
As described above, in the mobile phone 200, when the button is released during the time interval for transmitting the operation information after the button is pressed, the information indicating that the button is pressed and the button are released. The operation information including the information indicating that is transmitted to the digital camera 100. The digital camera 100 that has received this operation information performs a process corresponding to the user pressing a button. Then, the digital camera 100 performs a process corresponding to the user releasing the button after a waiting time shorter than the key repeat time has elapsed.
Therefore, when the user presses the button of the mobile phone 200 for a time shorter than the key repeat time, the key repeat occurs in the digital camera 100 even if the time interval during which the operation information can be transmitted is longer than the key repeat time. Can be avoided.
Therefore, it is possible to suppress the occurrence of key repeats contrary to the user's intention and allow the user to operate the remote controller.

Further, the digital camera 100 requests that when the time interval in which the mobile phone 200 can transmit the operation information is equal to or longer than the key repeat time, the connection time is set so that the time interval in which the mobile phone 200 can transmit the operation information is shorter than the key repeat time. Send to 200.
Therefore, after the connection time of this request is reflected, the information on the operation of the user for the mobile phone 200 is transmitted to the digital camera 100 in closer real time. Therefore, it is possible to suppress the occurrence of key repeats contrary to the user's intention and to operate the remote controller without delaying the user's operation.

Further, when the remote control operation for shooting is performed and the time interval during which the mobile phone 200 can transmit the operation information is equal to or longer than the key repeat time of the digital camera 100, the user's operation may be delayed. The digital camera 100 or the mobile phone 200 displays. Therefore, since the user can grasp that the operation may be delayed, the possibility that the shooting desired by the user fails can be reduced.
