For example, since it is considered that there are many states waiting for an operation by the user immediately after the power is turned on, the execution instruction generation unit 205 generates execution instruction data related to an operation standby function execution instruction.
Then, the second wireless processing unit 206 acquires the execution instruction data generated by the execution instruction generation unit 205 and transmits it to the imaging device 1 via the wireless PAN (step S3).

In the imaging apparatus 1, when the execution instruction data transmitted from the mobile device 2 is received by the wireless processing unit 107, the first instruction detection unit 108a acquires the execution instruction data and includes the plurality of functions. The execution instruction of any one of the functions is detected (step S4).
Next, the operation control unit 108 branches the process according to the function whose execution instruction is detected by the first instruction detection unit 108a (step S5). That is, when the first instruction detection unit 108a detects the execution instruction of the live view image transfer function (step S5; live view image), the operation control unit 108 proceeds to step S61 and executes the operation standby function. If an instruction is detected (step S5; standby operation), the process proceeds to step S71. If an instruction to perform a remote operation function is detected (step S5; remote operation), the process proceeds to step S81.

<Live view image transfer function>
When the execution instruction of the live view image transfer function is detected by the first instruction detection unit 108a (step S5; live view image), the mode specifying unit 108b has the first associated with the live view image transfer function. The communication mode is specified as the communication mode of the wireless processing unit 107 (step S61). Then, the mode specifying unit 108b outputs the information of the specified first communication mode to the memory 102.
Thereafter, the wireless processing unit 107 acquires information on the first communication mode from the memory 102, switches the communication mode to the first communication mode, and performs wireless communication with the portable device 2 (step S62). In this case, the communication speed between the wireless processing unit 107 of the imaging device 1 and the second wireless processing unit 206 of the portable device 2 can be increased.
Subsequently, the operation control unit 108 executes the live view image transfer program so that the wireless processing unit 107 connects the image data of the live view image generated by the image data processing unit 104 so that the wireless communication is possible. 2 are sequentially transmitted (step S63; live view image transfer function).

<Operation standby function>
When the execution instruction of the operation standby function is detected by the first instruction detection unit 108a (step S5; operation standby), the mode specifying unit 108b wirelessly processes the second communication mode associated with the operation standby function. The communication mode of the unit 107 is specified (step S71). Then, the mode specifying unit 108b outputs information on the specified second communication mode to the memory 102.
Thereafter, the wireless processing unit 107 acquires information on the second communication mode from the memory 102, switches the communication mode to the second communication mode, and performs wireless communication with the portable device 2 (step S72). In this case, only the operation signal input to the imaging device 1 can be detected, and power saving can be achieved.
Subsequently, the operation control unit 108 executes the operation standby program to maintain a state in which only a predetermined operation of the operation input unit 106 by the user is accepted (step S73; operation standby).

<Remote operation function>
When the first instruction detection unit 108a detects a remote operation function execution instruction (step S5; remote operation), the mode specifying unit 108b wirelessly processes the third communication mode associated with the remote operation function. The communication mode of the unit 107 is specified (step S81). Then, the mode specifying unit 108b outputs the specified third communication mode information to the memory 102.
Thereafter, the wireless processing unit 107 acquires information on the third communication mode from the memory 102, switches the communication mode to the third communication mode, and performs wireless communication with the portable device 2 (step S82). In this case, the wireless communication between the wireless processing unit 107 of the imaging device 1 and the second wireless processing unit 206 of the portable device 2 can achieve significant power saving with respect to “Bluetooth Classic”.
Subsequently, the operation control unit 108 executes a remote operation program, thereby maintaining a state of accepting an operation instruction according to a predetermined operation of the mobile device 2 connected to be wirelessly communicable by the wireless processing unit 107 (step S83). Remote control function).

  Thereafter, the wireless processing unit 107 acquires information indicating a function (for example, a live view image transfer function) executed by the operation control unit 108 among the plurality of functions, and the mobile device 2 via the wireless PAN. (Step S9).

  In the portable device 2, when the information transmitted from the imaging device 1 is received by the second wireless processing unit 206, the CPU of the central control unit 201 executes an application program corresponding to the function related to the acquired information. Then, the display control unit 208 generates an application screen corresponding to the application program being executed by the CPU of the central control unit 201, and outputs an image signal according to the generated application screen to the display unit 207 (step 207). S10).

  Note that when the imaging device 1 starts capturing and recording a moving image based on a predetermined operation of the imaging device 1 or the portable device 2 by the user, the imaging device 1 captures an image in the first communication mode. You may transmit the image data of a moving image to the portable apparatus 2. FIG. At this time, for example, even when the communication mode of the wireless processing unit 107 is switched, the moving image capturing and recording operation by the imaging device 1 is continued for a predetermined time or until a recording stop is instructed by the user. .

  Further, when an instruction to execute an application desired by the user is given based on a predetermined operation of the operation input unit 106 by the user, wireless processing is performed based on a function corresponding to the application program executed by the operation control unit 108. The communication mode of the unit 107 may be switched. That is, for example, when the execution of the remote operation program is instructed by the operation control unit 108 during execution of the live view image transfer function for performing wireless communication in the first communication mode, the communication mode of the wireless processing unit 107 is set. The third communication mode corresponding to the remote operation function is specified and automatically switched.

  As described above, according to the communication system 100 of the first embodiment, the imaging apparatus 1 detects an execution instruction for any one of a plurality of functions and responds to the one function for which the execution instruction is detected. Since one of the plurality of communication modes of the wireless processing unit 107 is selectively specified, a plurality of functions (for example, a live view image transfer function for sequentially transmitting a live view image to the portable device 2) Even in the case of the imaging device 1 having a remote operation function for receiving an operation instruction for operating the imaging device 1 transmitted from the portable device 2), an optimal communication mode for all functions is set in advance. Even if it is not set, communication can be performed by specifying an optimum communication mode for each function. That is, for example, in the case of the imaging apparatus 1 in which a plurality of communication modes are defined in accordance with, for example, power saving performance, communication data amount per one time, wireless communication possible range, communication frequency, etc., all functions in advance Setting an optimal communication mode is complicated for the user. Thus, by selectively specifying one communication mode corresponding to one function for which an execution instruction has been detected, communication can be performed in an optimal communication mode for each function.

  In addition, based on the execution instruction data transmitted from the mobile device 2 and received by the wireless processing unit 107, an execution instruction for any one of the functions can be detected. Specifically, since the execution instruction data is determined based on the execution history of a plurality of functions of the imaging device 1 recorded in the portable device 2, the execution history of each function executed by the imaging device 1 is obtained. Execution instruction data can be generated in consideration, and communication can be performed by specifying an optimal communication mode in accordance with the use state of the user.

[Embodiment 2]
The communication system according to the second embodiment will be described below with reference to FIGS.
The imaging device 1A and the portable device 2A constituting the communication system of the second embodiment have substantially the same configuration as the imaging device 1 and the portable device 2 of the first embodiment except for the details described below. Description is omitted.

First, the imaging apparatus 1A will be described with reference to FIG.
FIG. 6 is a block diagram illustrating a schematic configuration of an imaging apparatus 1A that configures the communication system according to the second embodiment to which the present invention is applied.

  As illustrated in FIG. 6, the wireless processing unit 107 of the imaging apparatus 1A according to the second embodiment includes a communication state acquisition unit 107b, and the operation control unit 108 includes a second instruction detection unit 108c and a mode identification unit 108b. It has.

The communication status acquisition unit 107b of the wireless processing unit 107 acquires the communication status with the mobile device 2A.
That is, the communication status acquisition unit (acquisition unit) 107b acquires the communication status of the wireless processing unit 107 with the mobile device 2A via a predetermined wireless communication line (for example, Bluetooth). Specifically, the communication state acquisition unit 107b receives the received signal strength (for example, RSSI (Received Signal Strength Indication)) of the signal transmitted from the second wireless processing unit 206 of the mobile device 2A and received by the communication antenna 107a. The communication state (radio wave environment) with the mobile device 2A is detected based on the amount of noise at the time of receiving the signal.
That is, since the signal is output at a constant output intensity from the second wireless processing unit 206 of the portable device 2A, the received signal strength increases as the distance to the second wireless processing unit 206 of the portable device 2A is shorter. The communication state is considered to be relatively good. On the other hand, it is considered that the received signal strength decreases as the distance to the second wireless processing unit 206 of the portable device 2A increases, and the communication state is relatively poor. In addition, it is considered that the closer the distance to the second wireless processing unit 206 of the mobile device 2A is, or the smaller the channel interference, the smaller the noise and the better the communication state. On the other hand, the farther the distance to the second wireless processing unit 206 of the mobile device 2A is, or the greater the channel interference, the greater the noise and the relatively poor communication state.
Further, the communication state acquisition unit 107b relatively detects, for example, the communication state with the mobile device 2A in a plurality of stages (for example, three stages such as “good”, “normal”, and “bad”).
Note that the received signal strength and the amount of noise exemplified for specifying the communication state are examples and are not limited to these, and can be arbitrarily changed as appropriate.

The second instruction detection unit 108c of the operation control unit 108 has a plurality of functions (for example, a live view image transfer function, an operation standby function, a remote operation function, etc.) based on the communication state acquired by the communication state acquisition unit 107b. An execution instruction for any one of the functions is detected.
That is, a plurality of communication states between the imaging device 1A and the portable device 2A and a plurality of functions executed by the operation control unit 108 are associated in advance using, for example, an association table (not shown). ing. Specifically, for example, “good” in which the communication state acquired by the communication state acquisition unit 107b is relatively good is associated with the live view image transfer function by the operation control unit 108, and the communication state is normal. The state “normal” and the remote operation function are associated with each other, and the communication state “bad” and the operation standby function are associated with each other.
Then, the second instruction detection unit 108c has a communication state (for example, “Good” acquired by the communication state acquisition unit 107b among a plurality of functions (for example, a live view image transfer function, an operation standby function, a remote operation function, etc.). The execution instruction of any one function (for example, a live view image transfer function etc.) associated with the

The mode specifying unit 108b is substantially the same as the imaging device 1 of the first embodiment, and the wireless processing unit 107 includes a plurality of communication modes according to one function whose execution instruction is detected by the second instruction detection unit 108c. To selectively specify one of the communication modes. That is, when the second instruction detection unit 108c detects an execution instruction for any one of the functions (for example, the live view image transfer function), the mode specifying unit 108b includes the first to third communication modes. The communication mode (for example, the first communication mode) associated with the function for which the execution instruction is detected is specified. Information on the communication mode specified by the mode specifying unit 108 b may be output to the memory 102 and temporarily stored in the memory 102.
The wireless processing unit 107 acquires communication mode information from the memory 102, switches to the communication mode specified by the mode specifying unit 108b, and performs wireless communication with the portable device 2A.

Next, the portable device 2A will be described with reference to FIG.
FIG. 7 is a block diagram showing a schematic configuration of a mobile device 2A constituting the communication system of the second embodiment to which the present invention is applied.

As illustrated in FIG. 7, the mobile device 2A according to the second embodiment includes a central control unit 201, a memory 202, a first wireless processing unit 203, a second wireless processing unit 206, a display unit 207, and a display control unit. 208, a transmission / reception unit 209, an operation input unit 210, and the like. That is, the portable device 2A is configured not to include the recording unit 204 and the execution instruction generating unit 205 provided in the portable device 2 of the first embodiment.
The configurations and functions of the central control unit 201, the memory 202, the first wireless processing unit 203, the second wireless processing unit 206, the display unit 207, the display control unit 208, the transmission / reception unit 209, and the operation input unit 210 are as described above. This is substantially the same as the portable device 2 of the first embodiment, and detailed description thereof is omitted.

<Communication processing>
Next, communication processing by the communication system according to the second embodiment will be described with reference to FIG.
FIG. 8 is a flowchart illustrating an example of an operation related to communication processing by the communication system.
The processes other than those described in detail below are substantially the same as the communication processes of the first embodiment, and detailed description thereof is omitted.

  As shown in FIG. 8, first, in substantially the same manner as in the first embodiment, the wireless processing unit 107 of the imaging device 1A and the second wireless processing unit 206 of the portable device 2A are connected so as to be capable of wireless communication via the wireless PAN. (Step S1).

Next, in the imaging apparatus 1A, the communication state acquisition unit 107b detects and acquires the communication state of the portable device 2A with the second wireless processing unit 206 by the wireless processing unit 107 (step S102). Specifically, the communication status acquisition unit 107b determines the received signal strength of the signal transmitted from the second wireless processing unit 206 of the mobile device 2A and received by the communication antenna 107a, the amount of noise when receiving the signal, and the like. Based on this, the communication state with the mobile device 2A is detected.
Subsequently, the second instruction detection unit 108c detects an execution instruction for any one of a plurality of functions based on the communication state acquired by the communication state acquisition unit 107b (step S103). Specifically, the second instruction detection unit 108c corresponds to the communication state acquired by the communication state acquisition unit 107b among a plurality of functions (for example, a live view image transfer function, an operation standby function, a remote operation function, etc.). An execution instruction for any one of the attached functions is detected. For example, the second instruction detection unit 108c detects an execution instruction for the live view image transfer function when “good” in a relatively good state is acquired as the communication state, and “normal” in the normal state as the communication state. "Is acquired, the remote operation function execution instruction is detected, and when the communication state is relatively bad" bad "is acquired, the operation standby function execution instruction is detected.

Subsequently, the operation control unit 108 branches the process according to the function whose execution instruction is detected by the first instruction detection unit 108a (step S5).
In addition, each process after step S5 is substantially the same as the said Embodiment 1. FIG.
That is, in step S5, when the first instruction detection unit 108a detects an execution instruction for the live view image transfer function (step S5; live view image), the mode specifying unit 108b determines that the live view image transfer function is The associated first communication mode is specified as the communication mode of the wireless processing unit 107 (step S61), and the wireless processing unit 107 switches the communication mode to the first communication mode and performs wireless communication with the mobile device 2A. Is performed (step S62). In this case, since the communication state is relatively “good”, large-capacity data communication such as a live view image can be performed.
In addition, when an instruction to execute the operation standby function is detected by the first instruction detection unit 108a in step S5 (step S5; operation standby), the mode specifying unit 108b is associated with the operation standby function. Is specified as the communication mode of the wireless processing unit 107 (step S71), and the wireless processing unit 107 switches the communication mode to the second communication mode and performs wireless communication with the portable device 2A (step S72). In this case, since the communication state is a relatively “bad” state, only the operation signal input to the imaging apparatus 1 can be detected, and power saving can be achieved.
In addition, when the execution instruction of the remote operation function is detected by the first instruction detection unit 108a in step S5 (step S5; remote operation), the mode specifying unit 108b is associated with the remote operation function. Is specified as the communication mode of the wireless processing unit 107 (step S81), and the wireless processing unit 107 switches the communication mode to the third communication mode and performs wireless communication with the portable device 2A (step S82). In this case, since the communication state is the “normal” state, it is possible to perform remote operation instruction communication with a relatively small amount of communication data per time.

As described above, according to the communication system of the second embodiment, as in the first embodiment, the imaging apparatus 1A detects an execution instruction for any one of a plurality of functions, and the execution instruction is detected. Since one of the plurality of communication modes of the wireless processing unit 107 is selectively specified according to the one function performed, the imaging apparatus 1A having a plurality of functions can be used in advance. Even if the optimal communication mode is not set for all functions, communication can be performed by specifying the optimal communication mode for each function.
In particular, the wireless processing unit 107 acquires a communication state with the portable device 2A via a predetermined communication line, and detects an execution instruction for one of a plurality of functions based on the acquired communication state. Therefore, it is possible to perform communication by specifying an optimum communication mode for each function executed in consideration of the communication state with the mobile device 2A.

In the second embodiment, the detection of the communication state between the imaging device 1A and the portable device 2A is performed on the imaging device 1A side. However, this is only an example and the present invention is not limited to this. For example, the portable device 2A You may go by side.
That is, the mobile device 2A detects the communication state with the imaging device 1A via the predetermined communication line by the second wireless processing unit 206, and transmits the detected communication state to the imaging device 1A by the second wireless processing unit 206. On the other hand, the imaging device 1A acquires a communication state transmitted from the portable device 2A and received by the wireless processing unit 107, and based on the acquired communication state, any one of a plurality of functions is obtained. An execution instruction for one function is detected, and one of the plurality of communication modes of the wireless processing unit 107 is selectively specified according to the one function for which the execution instruction is detected. It may be configured.

Further, for example, a configuration may be adopted in which the remaining amount of power stored in the power supply unit (not shown) of the imaging device 1 (1A) is detected and the function and the communication mode are switched according to the detected remaining amount of stored power.
Moreover, although the imaging apparatus 1 (1A) is illustrated as an electronic apparatus, it is an example and is not limited thereto, and can be arbitrarily changed as appropriate.

In addition, in the above-described embodiment, the first instruction detection unit 108a and the mode specification unit 108b are driven under the control of the central control unit 101 of the imaging apparatus 1 to function as the detection unit and the specification unit. However, the present invention is not limited to this, and may be realized by executing a predetermined program or the like by the CPU of the central control unit 101.
That is, a program including a detection processing routine and a specific processing routine is recorded in a program memory (not shown) for recording the program. Then, the CPU of the central control unit 101 may function as a means for detecting an execution instruction for any one of a plurality of functions by a detection processing routine. Further, means for selectively specifying any one communication mode among a plurality of communication modes of the communication means for the CPU of the central control unit 101 according to the one function for which the execution instruction is detected by the specifying processing routine You may make it function as.

  Similarly, the acquisition unit may be realized by executing a predetermined program or the like by the CPU of the central control unit 101 of the imaging apparatus 1.

Moreover, in the said embodiment, it is good also as a structure implement | achieved by a predetermined program etc. being performed by CPU of the central control part 201 of the portable apparatus 2 as a detection means and an identification means.
That is, a program including a detection processing routine and a specific processing routine is recorded in a program memory (not shown) for recording the program. Then, the CPU of the central control unit 201 may function as means for detecting an execution instruction for any one of a plurality of functions by a detection processing routine. Further, means for selectively specifying any one communication mode among a plurality of communication modes of the communication means for the CPU of the central control unit 201 according to the one function for which the execution instruction is detected by the specifying processing routine You may make it function as.

  Furthermore, as a computer-readable medium storing a program for executing each of the above processes, a non-volatile memory such as a flash memory or a portable recording medium such as a CD-ROM is applied in addition to a ROM or a hard disk. Is also possible. A carrier wave is also used as a medium for providing program data via a predetermined communication line.
