  Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, a command sharing function (hereinafter referred to as C function) that uses each other's functions among electronic devices (electronic cameras, mobile phones, printers, etc.) having a plurality of various functions is used.

[Configuration Example of Electronic Device 10]
FIG. 1 is a diagram illustrating a configuration example of an electronic device 10 according to an embodiment of the present invention. In FIG. 1, the electronic device 10 includes hardware 11 and software 12.

  The hardware 11 includes an electronic device circuit 13 for supporting the original function of the electronic device 10 and a communication circuit 14 (communication unit) for supporting the C function. For example, in the case of an electronic camera, an imaging circuit, a display circuit, a recording circuit, and the like correspond to the electronic device circuit 13. In the case of a mobile phone or the like, Bluetooth (registered trademark) or Wi-Fi that can communicate between electronic devices, separately from the original communication circuit of the telephone for communicating with a base station of a mobile phone communication network. Some of them are equipped with software that searches for a communication circuit corresponding to a standard such as (Wireless Fidelity (registered trademark)) and an electronic device corresponding to the same function in a range where communication is possible using the communication circuit. In the case of a portable telephone, it is not necessary to newly provide the communication circuit 14 and is included in the electronic device circuit 13. Here, the communication performed by the communication circuit 14 may be wireless communication or wired communication.

  The software 12 is based on an OS (operation system) that controls each part of the hardware 11 to realize the operation of the electronic device 10, and includes a control program 15 (control unit) and a C function platform 16 that are executed on the OS. .

  The control program 15 includes not only a program for realizing an original function corresponding to the operation of the electronic device 10 but also a program that uses a function installed in another device by the C function that is a feature of the present embodiment. For example, the control program 15 includes a program that controls processing for executing a command selected from a plurality of commands managed in the command sharing unit 18 described later in the execution order of the set commands. It should be noted that a program (or command execution timing) is given to the C function platform 16 (command processing unit 30) in any case of the program of the function of the own device and the function of other devices or a combination of both. The operation of issuing the event and obtaining the execution result is the same, and it is not necessary to be aware of whether the function is the function of the own device or the function of another device on the control program 15 side.

  The C function platform 16 includes a command sharing unit 18 (command management unit), a communication processing unit 19, a command search unit 22 (command search unit), and a command processing unit 30.

  The command sharing unit 18 manages commands that can be executed by the own device or other devices as a command list 20. For example, the command sharing unit 18 manages a plurality of commands including an external command that is a command for executing processing of a function provided in another device. The command registered in the command list 20 includes various information related to the command such as a command type, a command function name, and a parameter. However, the command list 20 is a list of commands, and a program for executing the command is in each electronic device. Also, in the command list 20, a list of internal commands that can be executed by the own device is registered in advance, but external commands that the communication processing unit 19 acquires from other devices connected by the communication circuit 14 are appropriately added. . Here, when the communication processing unit 19 detects that communication with another device that is the execution destination of the external command registered in the command list 20 is disconnected on the communication circuit 14, it is registered in the command list 20. Delete the command of the device. Note that the command list 20 managed by the command sharing unit 18 includes only the internal command or the external command in addition to the internal command and the external command. It may be in a state. Further, the command list 20 managed by the command sharing unit 18 may be in a state where at least one command is included.

  The communication processing unit 19 establishes communication based on a predetermined protocol via the communication circuit 14, and transmits / receives device information, command lists, events, etc., or transmits commands and receives execution results.

  The command search unit 22 searches for a command for executing processing of a function included in another device from another device to which the communication processing unit 19 is connected via the communication circuit 14. The available external commands searched by the command search unit 22 are appropriately added to the command list 20. For example, the command search unit 22 adds to the command list 20 an external command that can be executed by another device that can normally communicate by near field communication (for example, communication corresponding to the Bluetooth (registered trademark) standard). On the other hand, the command search unit 22 corresponds to the Wi-Fi (registered trademark) standard when adding an external command that can be executed by another device in an area wider than an area communicable by short-range communication to the command list 20. An external command that can be executed by another device that can communicate by communication is added to the command list 20. Note that the command search unit 22 changes the search area (changes the communication used for the search) in response to a command from the command processing unit 30.

  The command processing unit 30 executes a command managed by the command sharing unit 18 and acquires an execution result obtained by executing the command. Specifically, the command processing unit 30 refers to the command list 20 of the command sharing unit 18 and determines whether the command sent from the control program 15 is an internal command (command executed by the own device) or an external command (other device). Command to be executed in step 1). Then, when the command sent from the control program 15 is an internal command, the command processing unit 30 executes processing of the function corresponding to the internal command in its own device, and returns the execution result to the control program 15 side. Process.

  Further, when the command sent from the control program 15 is an external command, the command processing unit 30 transmits the external command from the communication processing unit 19 to another device connected via the communication circuit 14 of the hardware 11. . The command processing unit 30 receives the execution result obtained by executing the external command in the other device via the communication circuit 14 and the communication processing unit 19 and returns the result to the control program 15 side. .

  For example, the command processing unit 30 transmits an external command to another device via the communication circuit 14 (and the communication processing unit 19) according to the execution order of the commands controlled by the control program 15, and the other device executes the external command. The execution result which is the execution result obtained by doing is acquired. In addition, when the command processing unit 30 receives an external command (that is, a command to be executed by the own device) from another device, the command processing unit 30 executes the received external command on the own device and executes the execution result obtained by executing the command. Send to other devices.

The command processing unit 30 includes an information acquisition unit 31, a command selection unit 32 (selection unit), and a condition setting unit 33.
The information acquisition unit 31 acquires information indicating the performance of the own device or another device. The information acquisition unit 31 acquires information indicating the performance of the other device by communicating with the other device connected via the communication circuit 14. For example, the information acquisition unit 31 transmits a command requesting information indicating performance to another device, and acquires information indicating the performance of the other device by receiving information indicating the performance to which the other device responds. To do.

  Here, the information indicating the performance is, for example, information indicating the performance set in advance according to the function of each device (processing speed, processing accuracy and precision set in advance for each function, And the like). The information indicating the performance is, for example, information indicating the performance that changes with time (information indicating the resource state (for example, the CPU usage rate, the number of execution tasks, the remaining battery capacity, etc.)). Note that the information indicating the performance may be information indicating whether or not the required performance is satisfied. For example, the information indicating performance indicates whether or not the processing executed by the own device or other device satisfies the required performance (whether the processing satisfies a performance within a processing time of 500 msec or whether the performance satisfies a battery duration of 60 minutes or more. Or the like.

  The command selection unit 32 selects a command to be executed from among the plurality of commands based on information indicating the performance of a device that executes processing of a function corresponding to each of the plurality of commands managed by the command sharing unit 18. To do. For example, when the command sharing unit 18 manages a plurality of commands that execute the same function as the command executed by the control of the control program 15, the command selection unit 32 performs processing for each of the plurality of commands. Based on the information indicating the performance of the device to be executed, a command to be executed is selected from a plurality of commands for executing the same function.

  The condition setting unit 33 sets priority conditions for information indicating a plurality of performances of the own device or other devices. For example, the condition setting unit 33 gives priority to “processing speed” or “processing accuracy and precision” as a priority condition of information (processing speed, processing accuracy and precision, etc.) indicating the performance of a plurality of devices. ”And other priority conditions are set. Here, the condition setting unit 33 performs the above-mentioned priority based on conditions input by the user, preset conditions, or processing conditions (for example, shooting subject conditions when the electronic device 10 is an electronic camera). Set conditions. Then, the command selection unit 32, for example, executes a command to be executed from a plurality of commands that execute the same function based on the priority condition set by the condition setting unit 33 and the information indicating the performance in each device. select. Details of the command selection process will be described later.

  Thus, the electronic device 10 according to the present embodiment is configured, and a plurality of electronic devices 10 can share commands and use each other's functions.

[Operation Example of Electronic Device Cooperation System 100]
Next, a basic operation of the electronic device cooperation system 100 when the electronic camera 101 and the mobile phone 102 including the hardware 11 and software 12 corresponding to the C function are used as the electronic device 10 will be described.

FIG. 2 is a diagram illustrating an example of the operation of the electronic device cooperation system 100.
In FIG. 2, the electronic camera 101 has a shooting command 151, and the mobile phone 102 has an e-mail command 161 and a GPS (Global Positioning system) command 162. The shooting command 151 is a command for shooting the electronic camera 101. The e-mail command 161 is a command for sending and receiving e-mail. The GPS command 162 is a command for acquiring position information such as latitude and longitude.

  Then, after the communication processing unit 19 establishes communication (S101), the command sharing unit 18 of the electronic camera 101 and the mobile phone 102 establishes mutual device information and a command list 20 (in FIG. 2, a command list 131a, a command list). 132a). For example, the electronic camera 101 transmits to the mobile phone 102 that the device itself is a camera as device information, and has a shooting command 151 as an executable command list 131a (S102). Conversely, the mobile phone 102 transmits to the electronic camera 101 that the device itself is a mobile phone as device information, and has an email command 161 and a GPS command 162 as an executable command list 132a ( S103).

  As a result, the electronic camera 101 can have a command list 131b including the shooting command 151 of the own device, the e-mail command 161 of the mobile phone 102, and the GPS command 162. Similarly, the mobile phone 102 can have a command list 131b that includes an electronic mail command 161 and a GPS command 162 of its own device, and a shooting command 151 of the electronic camera 101. Note that a command list is transmitted and received, and a program for executing a command is in each electronic device.

  The command processing units 30 of the electronic camera 101 and the mobile phone 102 execute commands in the command list 20 held by the command sharing unit 18. For example, the electronic camera 101 can execute the shooting command 151 of the command list 131a, and the mobile phone 102 can execute the e-mail command 161 and the GPS command 162 of the command list 132a. Here, the command list 131a and the command list 132a are commands (internal commands) that are originally provided in the electronic camera 101 and the mobile phone 102, respectively. Furthermore, in the electronic device cooperation system 100 according to the present embodiment, commands (external commands) of other devices that are transmitted / received after establishment of communication can be used.

  For example, in FIG. 2, when the electronic camera 101 wants to acquire position information, the GPS command 162 is transmitted to the mobile phone 102 (S104), and the position information (latitude and longitude, etc.) acquired by executing the GPS command 162 on the mobile phone 102. Is transmitted to the electronic camera 101 (S105).

  In this way, the electronic camera 101 can acquire position information by GPS even if it is not equipped with a GPS function. For example, a new function that adds and stores position information to header information of a captured image is provided. Can be easily realized.

  FIG. 3 is a flowchart showing processing (initial operation) from when the electronic device is turned on until the command list is acquired in the electronic device cooperation system 100 according to the present embodiment.

  (Step S151) When the power of the electronic device 10 is turned on, the communication processing unit 19 of the C function platform 16 activates the communication circuit 14.

  (Step S <b> 152) Search for other electronic devices within a range in which communication is possible by the communication circuit 14. Such a function is determined by, for example, a standard such as Bluetooth (registered trademark), and an electronic device within a communicable range can be found.

  (Step S153) The communication processing unit 19 determines whether or not the detected electronic device is a device corresponding to the C function. If the detected electronic device does not correspond to the C function, the communication processing unit 19 returns to step S152 and continues to search for the electronic device. . If it corresponds to the C function, the process proceeds to step S154. The determination of whether or not the C function is supported can be realized, for example, by adding unique information indicating that the C function is available to control data transmitted and received when communication is established.

  (Step S154) The device information of the own device is transmitted to the other device corresponding to the C function found by the device search.

  (Step S155) Device information is received from another device corresponding to the C function found in the device search.

  (Step S156) The command list held by the own device is transmitted to another device.

  (Step S157) A command list held by another device is received from the other device.

  (Step S158) The command registered in the command list received from the other device is added to the command list held by the own device.

  In this way, in the electronic device cooperation system 100 according to the present embodiment, by executing a command list that can be executed with another device, the command of the other device is executed in the same manner as the command of the own device. Can do. In addition, since the execution of the command itself is performed on a device having the command, it is not necessary to install software and a driver program for executing the command as in the past, and it does not depend on the type of OS.

  FIG. 4 is a diagram illustrating processing for executing a command in the electronic camera 101 corresponding to the electronic device cooperation system 100 according to the present embodiment. FIG. 4A shows a processing example in which image processing A is performed on an image photographed by the electronic camera 101 and stored in a memory card or the like. Here, since the image processing command A is an external command that cannot be executed by the electronic camera 101, the image processing command A and the image data are transmitted to the image processing server 104 having the image processing program A, and the image processing server 104 performs the image processing A. The processed image data is returned to the electronic camera 101. The electronic camera 101 stores the image data subjected to the image processing A received from the image processing server 104 as a captured image in a memory card or the like.

  Further, FIG. 4B shows a flow of processing for performing image processing B on an image photographed by the electronic camera 101 and storing it in a memory card or the like. Here, since the image processing command B is an internal command that can be executed by the electronic camera 101, the image processing command B and the image data are sent to the control program in the own device, the image processing B is performed, and the processed image data is received. Save to a memory card.

  As described above, the electronic camera 101 in the electronic device cooperation system 100 according to the present embodiment can perform processing by issuing commands in the same manner without distinguishing between external commands and internal commands.

The control unit 204 is configured by a CPU that operates in accordance with, for example, an internally stored program (for example, the control program 15 in FIG. 1). The control unit 204 controls the operation of the entire electronic camera 101, for example, selects the shooting mode of the electronic camera 101 with the mode selection dial 263 of the operation unit 205, or controls the focus lens and aperture of the optical system 201 when the shutter button 262 is pressed. Control is performed to control the mechanical shutter or the electronic shutter of the imaging unit 202 to capture the subject image. Then, the control unit 204 performs control to read out the image data from the imaging unit 202 and load it into the buffer 203. Further, the control unit 204 conforms to predetermined image processing (white balance processing, color interpolation processing, gamma correction processing, saturation enhancement processing, contour enhancement processing, or JPEG standard) on the image data captured in the buffer 203. Image compression processing) is performed, and a predetermined file name and header information are registered (added) as additional information to the image data (for example, JPEG data) after the image processing, and stored in the memory card 207a. Alternatively, the image data captured in the buffer 203 is displayed on the display unit 206 as a captured image.
The control unit 204 includes, for example, the C function platform 16 and the control program 15 shown in FIG. In the following description regarding processing using the configuration of the electronic camera 101, the names of the respective units and the control program 15 included in the C function platform 16 shown in FIG. 1 and the control unit 204 shown in FIG.

  The operation unit 205 includes a power button 261, a shutter button 262, a mode selection dial 263, a menu button 264, a cross key 265, and the like. The user operates these operation buttons to use the electronic camera 101. Operation information from the operation unit 205 is output to the control unit 204, and the control unit 204 controls the operation of the electronic camera 101 in accordance with operation information input from the operation unit 205. For example, when the menu button 264 is pressed, the control unit 204 displays a menu screen for selecting the function of the electronic camera 101 on the display unit 206. Then, the menu screen is operated by operating the cross key 265. In particular, in the electronic camera 101 according to the present embodiment, when the menu button 264 is pressed, a command list as shown in FIG. 6 is displayed, and the functions of other devices can be used by selecting with the cross key 265. Alternatively, a new application function can be realized by combining these commands.

FIG. 7 is a diagram illustrating a command execution example of the electronic device cooperation system 100.
For example, as shown in FIG. 7, in the command list of the device 2, the commands of the function 1 to the function 3 are registered as the commands of the own device (internal commands), and the commands of the other device (device 2) (external) As commands, functions 4 and 5 are registered. As a result, the device 2 can use the five commands from function 1 to function 5. The device 2 can execute an application program in which these commands are combined. In the example of FIG. 7, the device 2 uses the command execution order 160 as a function 1 command of the device 2, a function 4 command of the device 1, a function 5 command of the device 1, a function 2 command of the device 2, and a device 2 in the order of the command of the function 3. The application program combining these commands is not limited to a combination of internal commands and external commands, and may be, for example, an application program combining only internal commands or only external commands.

  The display unit 206 includes a liquid crystal monitor or the like. Then, the control unit 204 displays a captured image, a setting menu, and the like.

  The memory card IF 207 is an interface for connecting the memory card 207 a to the electronic camera 101. The control unit 204 reads and writes image data to and from the memory card 207a via the memory card IF 207.

  The memory 208 is configured by a non-volatile semiconductor memory such as a flash memory, for example. The memory 208 stores parameters such as the shooting mode, exposure information, and focus information set in the electronic camera 101. In particular, in the present embodiment, a command list, device information, an event, and the like of the own device and other devices are stored.

  The communication unit 209 corresponds to the communication circuit 14 in FIG. 1 and corresponds to standards such as Bluetooth (registered trademark) and Wi-Fi (registered trademark) that can communicate between electronic devices.

  The above is the configuration and basic operation of the electronic camera 101.

[Operation Example of Electronic Device Cooperation System 100]
Next, an operation example of the electronic device cooperation system 100 using the electronic camera 101 will be described. The basic flow of operation is as follows.
(1) Establish communication between devices.
(2) Send information about the device itself to the other party.
(3) A command list that can be executed by the current device is transmitted to the partner device.
(4) Receive device information and command list from the counterpart device.
(5) When a command is received from the counterpart device, the command is executed and the execution result is returned.
(6) If necessary, a command is transmitted from the own device to the other device, and the execution result is received.

  FIG. 8 is an example of the operation of the electronic device cooperation system 100 when the electronic camera 10 and the mobile phone 102 are used to perform shooting processing as the electronic device 10 corresponding to the C function. Note that blocks and processes having the same reference numerals as those in FIG.

  In FIG. 8, after establishing communication between the electronic camera 101 and the mobile phone 102 (S101), as described with reference to FIG. 2, mutual device information and executable commands are transmitted and received (S102, S103). . The command list shown in FIG. 8 is a command list 131c and a command list 132c instead of the command list 131a and the command list 132a shown in FIG.

  The electronic camera 101 has a shooting command 151, an image processing command 152, an additional information registration command 153, and a save command 154. In addition, the mobile phone 102 has an e-mail command 161, a GPS command 162, and a simple position information acquisition command 163. The command sharing units 18 of the electronic camera 101 and the mobile phone 102 transmit and receive mutual device information and commands.

  Thereby, in addition to the command which the electronic camera 101 has, the electronic mail command 161, the GPS command 162, and the simple position information acquisition command 163 are added to the command list 131c which the electronic camera 101 has. On the other hand, a shooting command 151, an image processing command 152, an additional information registration command 153, and a save command 154 are added to the command list 132c of the mobile phone 102 in addition to the commands of the mobile phone 102.

  That is, the command list 131c of the electronic camera 101 and the command list 132c of the mobile phone 102 respectively include a shooting command 151, an image processing command 152, an additional information registration command 153, a save command 154, and an e-mail command 161. , A GPS command 162 and a simple position information acquisition command 163 are held.

[Example of command execution]
Next, in FIG. 8, when the electronic camera 101 executes the GPS command 162, the GPS command 162 is transmitted to the mobile phone 102 (S107). The mobile phone 102 executes the GPS command 162 to acquire position information such as latitude and longitude, and transmits a command response indicating the acquired position information to the electronic camera 101 (S108). The electronic camera 101 acquires position information by receiving a response command from the mobile phone 102.

  In this way, the electronic camera 101 can acquire current position information from the mobile phone 102. That is, for example, even if the electronic camera 101 does not have a GPS function, the position information can be acquired in the same manner as an electronic camera having a GPS function as if the GPS function is in its own function.

[Example of process execution procedure by control program]
Next, an example of an execution procedure of processing by the control program 15 will be described. Here, an example of the electronic device cooperation system 100 that operates the two electronic devices of the electronic camera 101 and the mobile phone 102 in cooperation with each other as illustrated in FIG. 8 will be described. An example will be described. This example assumes a usage scene of “adding location information to an image photographed by the electronic camera 101 in a tourist spot and storing it in the memory card 207a”. Here, as described with reference to FIG. 8, the two electronic devices, the electronic camera 101 and the mobile phone 102, transmit and receive device information and a command list to each other and share the same command list. . Available commands in this case include, for example, the shooting command 151, the image processing command 152, the additional information registration command 153, and the save command 154 of the electronic camera 101, the e-mail command 161, the GPS command 162, and the simple position of the mobile phone 102. An information acquisition command 163.

FIG. 9 is a flowchart illustrating an example of an execution procedure of processing (referred to as application program A) by the control program 15. The process of the application program A can be freely created by the user by combining the commands in the command list 131c, for example. For example, various application functions can be realized by arranging icons corresponding to the commands as described in FIG. 6 in the order of processing. In the present embodiment, it is assumed that an application program having the processing order shown in FIG. 9 has already been created.
Hereinafter, examples of execution procedures set in the control program 15 shown in FIG. 9 will be described in order.

  (Step S301: Issuing GPS command 162) The control unit 204 transmits a GPS command 162 from the command list 131c to the mobile phone 102 via the communication unit 209, and acquires position information as an execution result.

  (Step S302: Shutter button event) The control unit 204 determines whether or not the shutter button 262 has been pressed, and waits until the shutter button 262 is pressed. If the control unit 204 detects that the shutter button 262 has been pressed, the process proceeds to step S303.

  (Step S303: Shooting Command Issue) The control unit 204 issues a shooting command 151 from the command list 131c, and acquires a shot image as an execution result. For example, the control unit 204 causes the imaging unit 202 to acquire image data based on the subject image incident via the optical system 201 and output the image data to the buffer 203.

  (Step S304: Image processing command issuance) The control unit 204 issues an image processing command 152 from the command list 131c, and performs image processing (for example, white balance adjustment, contrast adjustment, JPEG compression, etc.) on the acquired captured image. The image data is generated by executing the process.

  (Step S305: Issue additional information registration command) The control unit 204 issues an additional information registration command 153 from the command list 131c, and converts the position information (latitude / longitude information or map data into address information from the map data acquired in step S301). The setting information and related information at the time of shooting including the file name may be registered (added) to the image data generated in step S304 as additional information.

  (Step S306; Save Command) The control unit 204 issues a save command 154 and saves the image data to which the additional information is added in step S305 to the memory card 207a via the memory card IF 207.

  Each command (or event) to be issued is sent to the command processing unit 30 of the C function platform 16 (C function platform 251 in the case of the electronic camera 101) of the own device or another device. Here, the OS corresponds to the control unit 204 in FIG. Then, the command processing unit 30 issues a command to a device that executes the command (internal command or external command), and acquires the execution result.

  Note that the processing by the control program 15 is not limited to processing in which external commands and internal commands are combined as in the processing by the application program A shown in FIG. 9, but only external commands are combined in accordance with the contents of processing. Or a combination of only internal commands.

  FIG. 10 is a flowchart illustrating an example of the operation of command execution processing. Referring to FIG. 10, in electronic device cooperation system 100 that operates two electronic devices of electronic camera 101 and mobile phone 102 in cooperation with each other, execution of processing (application program A) by control program 15 shown in FIG. An example of command execution processing when a command is executed according to the procedure will be described.

  First, the control unit 204 executes the GPS command 162 according to the execution procedure of the application program A. Specifically, the command processing unit 30 refers to the command list 20 of the command sharing unit 18 and confirms that the GPS command 162 received from the control program 15 is an external command to be executed on the mobile phone 102 (other device). It discriminate | determines and transmits the GPS command 162 to the mobile telephone 102 connected via the communication circuit 14 from the communication process part 19 (step S401).

  In response to the execution of the GPS command 162, the control unit 204 acquires position information that is an execution result. For example, the command processing unit 30 receives position information acquired by executing the GPS command 162 in the mobile phone 102 in response to the transmission of the GPS command 162 to the mobile phone 102 by a command response from the mobile phone 102. To do. Then, the command processing unit 30 returns the received position information to the control program 15 side (step S402).

  Next, the control unit 204 determines whether or not the execution result of the GPS command 162 has been acquired in step S402 (whether or not the execution process of the GPS command 162 has ended normally) (step S403).

If it is determined in step S403 that the execution result of the GPS command 162 has not been acquired, the control unit 204 executes error processing such as displaying a processing error, and ends the processing.
Note that the control unit 204 monitors the elapsed time in the process of step S403, and determines whether or not to perform a timeout process by detecting whether or not a time during which an execution result cannot be acquired has exceeded a predetermined time. May be. For example, if the elapsed time of processing has not exceeded a predetermined time, the control unit 204 returns to step S402 without performing time-out processing, and receives (acquires) the execution result of the GPS command 162 until time-out occurs. ) May be continued. On the other hand, the control unit 204 may terminate the process due to a timeout when the elapsed time of the process has exceeded a predetermined time. For example, the control unit 204 may terminate the process by executing an error process such as displaying a process error as the timeout process.

  On the other hand, if it is determined in step S403 that the execution result of the GPS command 162 has been acquired, the control unit 204 selects (moves to the next command) the next command according to the execution procedure of the application program A (step S450). ). For example, the control unit 204 permits the next acceptance of the shutter event, and selects the shooting command 151 when the shutter event is accepted.

  Next, the control unit 204 determines whether or not the next command has been selected in step S450, that is, whether or not all commands to be executed in accordance with the execution procedure of the application program A have been executed (command end) (step S450). S451). At this time, since the control unit 204 selects the shooting command 151 as the next command, the process returns to step S401, and the shooting command 151 is transmitted from the control program 15 to the command processing unit 30. In step S401, the command processing unit 30 refers to the command list 20 of the command sharing unit 18, and determines that the shooting command 151 received from the control program 15 is an internal command to be executed in the electronic camera 101 (own device). Then, the shooting command 151 is executed.

  Then, the control unit 204 executes the processing of steps S401 to S406 in the order of the shooting command 151, the image processing command 152, the additional information registration command 153, and the save command 154 according to the execution procedure of the application program A. If it is determined in step S451 that all commands executed according to the execution procedure of the application program A have been executed (command end), the control unit 204 ends the process.

  As described above, in the electronic device cooperation system 100 according to the present embodiment, the control unit 204 of the electronic camera 101 transmits the external command to the mobile phone 102 in accordance with the command execution procedure set in the control program 15. In addition to being executed on the telephone 102, internal commands can be executed on the electronic camera 101. Then, the control unit 204 can execute the command of the next procedure after acquiring the execution result of the external command or the internal command executed according to the command execution procedure set in the control program 15.

  In the process described with reference to FIG. 10, for example, if it is determined in step S403 that the execution result cannot be acquired, the execution of the next command is awaited until it is acquired, or the process cannot be acquired. There is a problem of being interrupted and exiting. For example, in the execution procedure of the application program A shown in FIG. 9, if the electronic camera 101 cannot acquire the execution result of the GPS command 162 from the mobile phone 102, it cannot accept the shutter button event until the acquisition. The shooting command 151 cannot be executed.

  Here, the case where the execution result of the GPS command 162 cannot be acquired from the mobile phone 102 is, for example, the case where the mobile phone 102 is not ready to execute the GPS command 162 depending on the operation state or the like, or the processing by the GPS command 162 This is the case when the execution result acquisition is delayed (when it takes a long time to acquire positioning data). In addition, when the application program A shown in FIG. 9 is created, communication with the mobile phone 102 is possible, but when the application program A is executed, communication with the mobile phone 102 is disabled. The electronic camera 101 cannot acquire the execution result of the GPS command 162. In such a case, since the electronic camera 101 cannot perform the photographing process, the shutter timing may be missed. In addition, the processing of the application program A may be interrupted due to the failure to obtain the execution result.

  As described above, when a command is executed in accordance with the command execution procedure set in the control program 15 (application program A execution procedure), in particular, the operation status of other devices, the location (location) conditions of other devices, and the like. Depending on the reason, the execution result of the external command executed by another device may not be acquired. When the execution result of the command cannot be acquired as described above, the electronic device cooperation system 100 according to the present embodiment executes an alternative command that can acquire an execution result (alternative execution result) that replaces the execution result of the command. That is, the electronic device cooperation system 100 executes an alternative command for acquiring an alternative execution result instead of a command for which an execution result cannot be acquired. Thereby, in the electronic device cooperation system 100, the alternative execution result acquired by executing the alternative command can be used as a substitute for the execution result that could not be acquired.

For example, when the electronic camera 101 cannot acquire the execution result of the GPS command 162 from the mobile phone 102, the electronic camera 101 executes an alternative command that can acquire position information instead of the GPS 162. Then, the electronic camera 101 acquires position information (substitution execution result) obtained by the substitute command executed instead of the GPS command 162 that could not be obtained.
Hereinafter, a process (alternative process) of acquiring an alternative execution result by executing an alternative command of a command when the execution result of the command cannot be acquired will be described in detail.

[Description of command execution processing using alternative processing]
The command processing unit 30 may not be able to acquire a first execution result that is an execution result that should be obtained by executing the first command included in the command managed by the command sharing unit 18. In this case, the command processing unit 30 executes a second command that substitutes for the first command. Then, the command processing unit 30 acquires the second execution result obtained by executing the second command as an execution result (substitute execution result) that replaces the first execution result.

  The procedure for executing the application program A described with reference to FIG. 9 will be described as an example. First, the control unit 204 transmits a GPS command 162 from the command list 131c to the mobile phone 102 via the communication unit 209. Here, for example, when the mobile phone 102 cannot receive a radio wave from a GPS satellite, it cannot acquire position information that should be obtained by executing the GPS command 162. Therefore, the control unit 204 cannot acquire the execution result of the GPS command 162. Therefore, the control unit 204 acquires position information (substitution execution result) by executing an alternative command (for example, a simple position information acquisition command 163) that substitutes for the GPS command 162 (step S301).

  Next, the control unit 204 controls the acquisition of the shutter button event, and when detecting that the shutter button 262 has been pressed (step S302), issues (executes) a shooting command 151 and takes a shot as an execution result. An image is acquired (step S303). Then, the control unit 204 performs image processing (issues an image processing command 152) on the acquired captured image to generate image data (step S304). Here, the processing of the shutter button event (step S302), the shooting command issuance (step S303), and the image processing command issuance (step S304) is executed regardless of the position information obtained by executing the GPS command 162. It is possible processing.

  Subsequently, the control unit 204 performs processing for issuing an additional information registration command in step S305. In this process, the control unit 204 registers (adds) the position information as the substitute execution result acquired in step S301 described above to the image data (step S305). Then, the control unit 204 issues a save command 154, and saves the image data to which the position information acquired as the above alternative execution result is added to the memory card 207a (step S306).

  As described above, when the position information cannot be acquired as the execution result of the GPS command 162 that is the external command transmitted to the mobile phone 102, the control unit 204 substitutes for the GPS command 162 (for example, a simple position information acquisition command). 163) is executed to acquire position information, and the next command is executed according to the execution procedure of the control program 15 (application program A). Thereby, the control unit 204 can continuously execute the process of the control program 15 without interrupting the process. That is, even when the electronic camera 101 cannot acquire the position information by the GPS function of the mobile phone 102, the electronic camera 101 can acquire the alternative position information and continue the processing so that the photographing operation can be performed. Can do.

  Here, the command sharing unit 18 manages commands (internal commands or external commands) registered in the command list 20 so that they can be identified for each function type. For example, the command sharing unit 18 manages the commands registered in the command list 20 so as to be categorized and identified for each function group.

  FIG. 11 is a diagram showing the classification of commands registered in the command list 20 for each function group. This figure shows an example of classification of each command for each functional group when the electronic camera 101, the mobile phone 102, and the image processing server 104 share each other's commands. This function group is identified (classified) based on, for example, a command function name (photographing function, position information acquisition function, printer function, image processing function, super-resolution image processing function, face detection function, etc.) included in the command.

  In the example shown in FIG. 11, the shooting function group G101 includes a still image shooting command and a moving image shooting command that the electronic camera 101 has, and a still image shooting command and a moving image shooting command that the mobile phone 102 has. The location information acquisition function group G102 includes a GPS command 162 and a simple location information acquisition command 163 that the mobile phone 102 has. The image quality adjustment function group G103 includes image processing commands that the electronic camera 101 has and image processing commands that the image processing server 104 has. The face detection function group G104 includes a face detection command that the electronic camera 101 has and a face recognition command that the image processing server 104 has.

  Multiple commands included in the same function group are equivalent to each other, or the basic functions are the same even if the details of the functions are different. An alternative execution result can be acquired. For example, by executing the simple position information acquisition command 163 instead of the GPS command 162 as an alternative process, the position accuracy is inferior to the position information based on the GPS positioning data, but the location of the base station of the mobile phone communication network Can be acquired as a substitute execution result.

  For example, when the electronic camera 101 (command processing unit 30) cannot acquire the position information in response to executing the GPS command 162 (first command), the GPS command 162 (managed by the command sharing unit 18) ( Among the commands including the first command), commands (for example, the simple position information acquisition command 163) identified by the function type of the GPS command 162 (first command) except for the GPS command 162 (first command) Execute as an alternative command (second command) That is, the control unit 204 (command processing unit 30) of the electronic camera 101 transmits the simple position information acquisition command 163 included in the same function group (position information acquisition function group G102) as the GPS command 162 to the mobile phone 102. . Then, the mobile phone 102 transmits the position information acquired by executing the simple position information acquisition command 163 to the electronic camera 101. As a result, the control unit 204 (command processing unit 30) of the electronic camera 101 acquires position information (substitution execution result) that is an execution result of the simple position information acquisition command 163 (substitution command) from the mobile phone 102.

  As described above, the electronic camera 101 (control unit 204) is identified as the same function as the GPS command 162 when the command processing unit 30 cannot acquire the position information obtained by executing the GPS command 162 (the same function group). A simple position information acquisition command 163 that replaces the GPS command 162 is executed. Thereby, the electronic camera 101 (control unit 204) can acquire the position information obtained in the mobile phone 102 by executing the simple position information acquisition command 163 as an alternative execution result.

  The function group may be identified for each more detailed function based on a command ID (a unique ID or command name predetermined for each command) included in the command. For example, the position information acquisition function group G102 may be classified and distinguished into a GPS function group G102a and a simple position information acquisition function group G102b. Also. The shooting function group G101 may be classified and distinguished into a still image shooting function group G101a and a moving image shooting function group G101b.

(Specific examples of alternative commands)
Next, a specific example of the alternative command will be described.
FIG. 12 is a diagram illustrating a first example of an alternative command. The electronic camera 101, the mobile phone 102, and the image processing server 104 shown in this figure are in a communicable area 300, and each command can be identified by function type as described with reference to FIG. As you can see, it is possible to share and use each other's functions. Here, the electronic camera 101 transmits a GPS command 162 to the mobile phone 102 in order to use the GPS function of the mobile phone 102. However, since the mobile phone 102 is in a building (indoor), it cannot acquire position information by GPS. That is, even if the electronic camera 101 executes the GPS command 162, it cannot obtain the execution result. In this case, the electronic camera 101 uses, as an alternative command, a simple position information acquisition command 163 that executes processing of the simple position information acquisition function of the mobile phone 102 instead of the GPS command 162 that executes processing of the GPS function of the mobile phone 102. Execute (send to mobile phone 102). Thereby, the electronic camera 101 can acquire the position information obtained by executing the process of the simple position information acquisition function of the mobile phone 102 as an alternative execution result.

  FIG. 13 is a diagram illustrating a second example of an alternative command. The example shown in this figure is an area where the mobile phone 102A can communicate after the electronic camera 101, the mobile phone 102A, the mobile phone 102B, and the image processing server 104 are in the communicable area 300. This is an example when moving out of 300. In the electronic camera 101, when an application program using the GPS (A) function of the mobile phone 102A is created and the mobile phone 102A moves out of the communicable area 300, the GPS (A ) Function cannot be used. That is, even if the electronic camera 101 executes the GPS command 162, it cannot obtain the execution result. In this case, instead of executing the GPS (A) function processing of the mobile phone 102, the electronic camera 101 carries a command for executing the GPS (B) function processing of the mobile phone 102B included in the same GPS function group G102a. Send to phone 102B. Thereby, the electronic camera 101 can acquire the position information obtained by executing the process of the GPS (B) function of the mobile phone 102B as an alternative execution result.

(Explanation of alternative processing operation)
Next, with reference to FIG. 14, an example of a command execution process operation using an alternative process in the electronic device cooperation system 100 will be described.

  FIG. 14 is a flowchart illustrating an example of command execution processing using alternative processing. This figure shows an example of a process for executing a simple position information acquisition command 163 as an alternative process when the execution result of the GPS command 162 cannot be acquired in the command execution process described with reference to FIG. Yes. In FIG. 14, portions corresponding to the respective processes in FIG. 10 are denoted by the same reference numerals, and description thereof is omitted.

  If it is determined in step S403 that the execution result of the GPS command 162 has not been acquired, the control unit 204 executes alternative command search processing (step S410). For example, the command processing unit 30 searches the command list 20 for a command included in the same function group (position information acquisition function group G102) as the GPS command 162 as an alternative command replacing the GPS command 162.

  Next, the control unit 204 determines whether or not the search for an alternative command that substitutes for the GPS command 162 has succeeded. For example, the command processing unit 30 determines whether the command list 20 includes an alternative command that substitutes for the GPS command 162 (step S421).

  In step S421, when it is determined that the search for the alternative command has succeeded (there is an alternative command), the control unit 204 executes the searched alternative command. For example, the command processing unit 30 transmits a simple position information acquisition command 163 to the mobile phone 102 as a command that substitutes for the GPS command 162. That is, the control unit 204 executes the simple position information acquisition command 163 as an alternative process of the GPS command 162 (step S422).

  Next, the control unit 204 (command processing unit 30) acquires the position information (substitute command execution result and alternative execution result) obtained by executing the simple position information acquisition command 163 from the mobile phone 102 ( Step S423). Subsequently, the control unit 204 advances the processing to step S450, and, as described with reference to FIG. 10, the processing of steps S401 to S406 is performed according to the execution procedure of the application program A, the shooting command 151, the image processing command 152, The additional information registration command 153 and the save command 154 are executed in this order, and the process ends.

  On the other hand, if it is determined in step S421 that the search for the substitute command has failed (no substitute command), the control unit 204 selects an error display indicating that there is no substitute command, and whether to end the process. Possible menu displays are displayed on the display unit 206 (step S425). Then, the control unit 204 determines whether or not to end the process (whether or not to end with an error) in accordance with a user operation input to a menu that can select whether or not to end the process (step S426). .

  If it is determined in step S426 that the process is to be terminated (error termination), the control unit 204 terminates the command execution process (error termination). On the other hand, if it is determined in step S426 that the process is not to be ended (the error is not ended), the control unit 204 advances the process to step S450 and proceeds to an execution process for the next command.

  As described above, when the position information cannot be acquired as the execution result of the GPS command 162 that is the external command transmitted to the mobile phone 102, the control unit 204 (command processing unit 30) substitutes for the GPS command 162 (for example, The position information of the alternative execution result is acquired by executing the simple position information acquisition command 163).

  Thereby, for example, even when the electronic camera 101 cannot acquire the position information by the GPS function of the mobile phone 102, the position information by the simple position information acquisition function for acquiring the position information replacing the GPS function is used as the alternative execution result. Can be acquired. Therefore, the electronic camera 101 can continue the process so that the photographing operation can be performed. That is, even if the electronic camera 101 cannot acquire the execution result of the command executed in the control program 15, it can acquire the alternative execution result by the alternative command and can continue without interrupting the processing of the control program 15. Can be executed.

  FIG. 15 is a flowchart illustrating an example of an alternative command search process. Next, with reference to FIG. 15, the operation of the alternative command search process in step S410 of FIG. 14 will be described in detail.

  First, the command processing unit 30 searches the command list 20 for commands included in the same function group (for example, the position information acquisition function group G102) as the command (for example, the GPS command 162) for which the execution result could not be acquired. (Step S412).

  Next, the command processing unit 30 determines whether there is a command included in the same function group in the command list 20, that is, whether there is a replaceable command (step S412).

  In step S412, when it is determined that there is a command that can be replaced, the command processing unit 30 determines a command (for example, the simple position information acquisition command 163) included in the searched function group as a replacement command ( In step S415, it is determined that the search is successful (there is an alternative command) (step S416), and the process is terminated.

  On the other hand, if it is determined in step S412 that there is no replaceable command, the command processing unit 30 determines that the search has failed (no substitute command) (step S419), and ends the process.

  As described above, the command processing unit 30 searches for a command (for example, the simple position information acquisition command 163) included in the same function group as the command whose execution result could not be acquired (for example, the GPS command 162) as an alternative command. Can be determined.

  When the command processing unit 30 does not acquire the execution result of the command for executing the GPS (A) function processing of the mobile phone 102A as shown in FIG. 13, the same function group as the command for executing the GPS (A) function is obtained. The command for executing the processing of the GPS (B) function of the mobile phone 102B included in the mobile phone 102B may be determined as an alternative command. In this case, since the electronic camera 101 can acquire position information based on GPS positioning data, for example, it can acquire position information with better detection accuracy than the position information detected by the simple position information function (A).

  FIG. 16 is a flowchart illustrating another example of the alternative command search process. The search process shown in FIG. 16 can be replaced when it is determined in step S412 of FIG. 15 that there is no command included in the same function group in the command list 20, that is, there is no replaceable command. A process for searching for a command (search, search) is executed. In FIG. 16, portions corresponding to the respective processes in FIG. 15 are denoted by the same reference numerals, and description thereof is omitted.

  In step S412, when it is determined that there is no alternative command, the command processing unit 30 causes the command search unit 22 to search for a device capable of function cooperation. For example, the command search unit 22 searches a search range from an area range communicable by communication corresponding to the Bluetooth (registered trademark) standard to an area communicable by communication corresponding to the Wi-Fi (registered trademark) standard. The range is expanded and a device capable of function cooperation is searched (step S417).

  If there is a device that can be newly linked by the search processing in step S417, a command that can execute the process of the function of the device that can be linked is added to the command list 20 of the command sharing unit 18. The

  Next, the command processing unit 30 determines whether there is a device that can be newly linked. For example, the command processing unit 30 determines whether or not there is a device that can be newly linked based on whether or not a new command is added to the command list 20 of the command sharing unit 18 (step S418).

  If it is determined in step S418 that there is a device that can be newly linked, the command processing unit 30 returns the process to step S411, and again, from the command list 20, a command (for example, GPS) whose execution result could not be acquired. A command included in the same function group as the command 162) is searched.

  On the other hand, if it is determined in step S418 that there is no new device that can be linked, the command processing unit 30 determines that the search has failed (no substitute command) (step S419), and ends the process.

  As described above, the command processing unit 30 includes a command that can be used as an alternative command when there is no command included in the same function group as the command (for example, the GPS command 162) for which the execution result could not be acquired. The command search unit 22 is searched for possible devices. Thereby, when there is no substitute command in the command list 20, the command processing unit 30 can search for a substitute command from the command of the device that can be linked by searching for a new device that can be linked.

(Process to select an alternative command from multiple commands)
There may be a plurality of commands included in the same function group as the command (for example, the GPS command 162) for which the execution result could not be acquired. For example, in the example illustrated in FIG. 13, there are a command for executing the process of the GPS (B) function of the mobile phone 102 </ b> B and a command for executing the process of the simple position information acquisition (B) function of the mobile phone 102 </ b> B. In this case, the command processing unit 30 has a GPS (B) function that can obtain the same detection accuracy as a command for which an execution result could not be obtained (for example, a command that executes the GPS (A) function of the mobile phone 102A). You may select the command which performs a process. In addition, when the processing time of the simple position information acquisition (B) function is shorter than the processing time of the GPS (B) function, the command processing unit 30 selects a command for executing the processing of the simple position information acquisition (B) function. May be.

  In other words, except for the command (first command) for which the command sharing unit 18 could not obtain the execution result, a plurality of commands included in the function group of the first command (identified by the function type of the first command). When the command is managed, the command processing unit 30 selects an alternative command (second command) from the plurality of commands. For example, the command selection unit 32 of the command processing unit 30 selects an alternative command based on information indicating the performance of a device that executes the processing of each of the plurality of commands.

Here, the above-described information indicating the performance is information indicating the performance set in advance according to the function, for example, and is included in the information included in each command, for example. An example of information indicating performance is shown below.
Processing speed: The processing speed that affects the processing time required to execute the command and acquire the execution result.
Processing accuracy and precision: The level of execution results obtained by processing. For example, when the GPS function is compared with the simple position information acquisition function, the GPS function can acquire the position information more accurately (accurately).
-Location of each device: Location of the other device that executes the command to its own device. For example, when the location of the own device is detected using the GPS function of the other device, the location (distance) of the other device relative to the own device affects the performance of the detected position.
-Ambient environment: Ambient environmental conditions (conditions such as temperature and humidity) that affect the performance of processing results.

  The command selection unit 32 selects a command to be executed based on information indicating the performance set in advance according to the function as shown in the above example.

  Note that the command selection unit 32 may use the command function name and the command ID as information indicating the above-described performance. In addition, the command selection unit 32 selects device information (for example, device type information, device ID, manufacturer ID) in order to select a command for executing processing of a function of another device that performs processing suitable for the device itself. , Information indicating the model number, etc.) may be used as information indicating the above-described performance. Further, the command selection unit 32 uses information indicating the owner of each device (owner ID), information indicating sex, age, etc., or information indicating country (country ID) as information indicating the above-described performance. May be used. Further, the information indicating the performance described above may be information indicating the performance (for example, the resource state of the device) that changes over time.

  Note that the command selection unit 32 selects, as an alternative command, a command having a similar data format that can replace the data format obtained as an execution result.

(Specific example of selecting an alternative command from multiple commands)
Next, a specific example of selecting an alternative command from a plurality of commands will be described.
FIG. 17 is a diagram illustrating a first example of selecting an alternative command from a plurality of commands. Since the electronic camera 101, the mobile phone 102A, the mobile phone 102B, the image processing server 104, and the navigation terminal device 106 shown in this figure are within the communicable area 300, the mobile phone 102A communicates thereafter. This is an example when moving outside the possible area 300. That is, in a state where all the devices described above are in the communicable area 300, the position information acquisition function group G102 includes the GPS (A) function processing and the simple position information acquisition (A) function of the mobile phone 102A. A command for executing each process, a command for executing a GPS (B) function process and a simple position information acquisition (B) function of the mobile phone 102B, and a GPS (C) function process of the navigation terminal device 106, respectively. A command to execute is included.

  Here, when the electronic camera 101 has executed a command for executing processing of the GPS (A) function of the mobile phone 102A, if the mobile phone 102A has moved outside the communicable area 300, the electronic camera 101 The execution result of the GPS (A) function process cannot be acquired. Therefore, the electronic camera 101 executes a command selected from a plurality of commands in the position information acquisition function group G102 as an alternative command. For example, the command selection unit 32 includes a command for executing GPS (B) function processing, a command for executing simple position information acquisition (B) function processing, and a command for executing GPS (C) function processing. The alternative command is selected based on the information indicating the performance of the device on which each command is executed.

  For example, among the processing of the GPS (B) function, the processing of the simple position information acquisition (B) function, and the processing of the GPS (C) function, the processing of the simple position information acquisition (B) function is the fastest processing speed processing. It is assumed that the GPS (C) function process is a process capable of acquiring the most accurate position. In this case, for example, when the priority condition set in the condition setting unit 33 is “priority of processing speed”, the command selection unit 32 issues a command for executing processing of the simple position information acquisition (B) function. Select as an alternative command. Thereby, the electronic camera 101 can acquire the position information obtained by executing the process of the simple position information acquisition (B) function giving priority to the processing speed as an alternative execution result.

  Further, for example, when the priority condition set in the condition setting unit 33 is “priority is given to processing accuracy and precision”, the command selection unit 32 substitutes a command for executing the processing of the GPS (C) function. Select as a command. Thereby, the electronic camera 101 can acquire, as an alternative execution result, the position information obtained by executing the GPS (C) function process giving priority to the accuracy and precision of the process.

  FIG. 18 is a diagram for explaining a second example of selecting an alternative command from a plurality of commands. The electronic camera 101, the mobile phone 102, the image processing server 104B, and the image processing server 104C shown in this figure are examples of a state in the communicable area 300, and each command is assigned to each function type. They are shared so that they can be identified (classified by function group), and the functions of each other can be used. For example, the image quality adjustment function group G103 includes a command for executing processing of the image processing (A) function of the electronic camera 101, a command for executing processing of the image processing (B) function of the image processing server 104B, and an image processing server 104C. A command for executing the processing of the image processing (C) function is included.

  Here, when the electronic camera 101 executes a command for executing the processing of the image processing (B) function of the image processing server 104B, the processing of the image processing (B) function does not end normally in the image processing server 104B. Suppose. For example, when the electronic camera 101 acquires an error response without acquiring the execution result in response to executing a command for executing the processing of the image processing (B) function, the processing of the image processing (A) function An alternative command is selected from the command for executing the image processing and the command for executing the processing of the image processing (C) function.

  For example, among commands that execute processing of the image processing (A) function and commands that execute processing of the image processing (C) function, processing of the image processing (A) function is processing at the fastest processing speed, Assume that the processing of the image processing (C) function is image processing (image processing with the best image quality after image processing) in which the most accurate color reproduction processing or precise noise reduction processing is performed. In this case, for example, when the priority condition set in the condition setting unit 33 is “priority of processing speed”, the command selection unit 32 replaces the command for executing the processing of the image processing (A) function with an alternative command. Choose as. Thereby, the electronic camera 101 can acquire an image obtained by executing the processing of the image processing (A) function giving priority to the processing speed as an alternative execution result.

  Further, for example, when the priority condition set in the condition setting unit 33 is “priority is given to processing accuracy and precision”, the command selection unit 32 issues a command for executing processing of the image processing (C) function. Select as an alternative command. Thereby, the electronic camera 101 can acquire an image obtained by executing the processing of the image processing (C) function giving priority to the accuracy and precision of processing as an alternative execution result.

(Operation of selecting an alternative command from multiple commands)
Next, with reference to FIG. 19, an example of the operation of selecting an alternative command from a plurality of alternative commands in the alternative command search process will be described.

  FIG. 19 is a flowchart illustrating an example of an alternative command search process using a process of selecting an alternative command from a plurality of commands. This figure is different from the alternative command search process shown in FIG. 15 in that a process of selecting an alternative command (steps S413 and S414) is executed when there are a plurality of alternative commands. In FIG. 19, parts corresponding to the respective processes in FIG.

  If it is determined in step S412 that there are replaceable commands, the command processing unit 30 determines whether there are a plurality of replaceable commands (step S413). When it is determined in step S413 that there are a plurality of replaceable commands, the command selection unit 32 selects a replace command from the replaceable commands based on the information indicating the performance. For example, the command selection unit 32 selects, as an alternative command, a command corresponding to the performance in accordance with the priority condition set by the condition setting unit 33 among a plurality of alternative commands (step S414). Then, the command processing unit 30 determines the command (alternative command) selected by the command selection unit 32 in step S414 as an alternative command (step S415).

  On the other hand, if it is determined in step S413 that there is one replaceable command, the command processing unit 30 advances the processing to step S415, and determines a command included in the searched function group as a replacement command.

  Thus, when there are a plurality of commands included in the same function group as the command for which the execution result could not be obtained, the command processing unit 30 determines the performance (processing speed, processing accuracy, etc.) from the plurality of commands. The alternative command is selected according to the priority condition. Thereby, the command processing unit 30 can appropriately select an alternative command to be executed instead of the command for which the execution result could not be acquired.

  As described above, according to the electronic device cooperation system 100 of the above embodiment, the electronic device 10 (for example, the electronic camera 101) acquires the execution result of the external command executed by another device (for example, the mobile phone 102). Even if it is not possible, it is possible to acquire an alternative execution result that replaces the execution result that could not be acquired by executing an alternative command that replaces the external command that could not acquire the execution result. For example, the electronic device 10 can execute, as an alternative command, a command identified by the same function type as an external command for which an execution result could not be obtained. In addition, the electronic device 10 selects a command based on information indicating performance from a plurality of commands identified by the same function type as the external command for which an execution result could not be acquired (a command selected according to performance priority conditions). Can be executed as an alternative command.

  Therefore, the electronic device 10 can acquire the alternative execution result even when the execution result of the command executed according to the process of the control program 15 cannot be acquired depending on the state of the other device, and the process of the control program 15 Can be executed continuously without interruption.

  In the above embodiment, an alternative process for executing an alternative command that replaces the external command when the execution result of the external command executed on the other device cannot be obtained has been described. When the result cannot be acquired, an alternative process for executing an alternative command that replaces the internal command may be used. In other words, according to the electronic device cooperation system 100 of the above-described embodiment, the electronic device 10 has the same function as the function of another device that executes processing by an external command and the function of its own device that executes processing by an internal command. Can be used.

  Therefore, according to the electronic device cooperation system 100 of the above-described embodiment, even if the electronic device 10 cannot acquire the execution result of the command executed in the own device or another device according to the processing of the control program 15, the substitute command The alternative execution result by can be acquired. That is, even when the electronic device cannot acquire the execution result of the command executed according to the process of the control program 15, it can continuously execute the process of the control program 15 without interruption.

  Thus, according to this embodiment, various functions of other devices can be used in the same manner as the functions of the own device.

  Further, in the above-described embodiment, the alternative processing when the execution result obtained by executing the processing of the position information acquisition function or the processing of the image quality adjustment function cannot be acquired has been described, but the processing can be similarly applied to the processing of other functions. it can.

  Further, in the above-described embodiment, the alternative process when the electronic camera 101 executes the internal command of the own device and the external command of the other device is described as an example. However, the electronic device 10 other than the electronic camera 101 may Alternatively, it may be an alternative process when the internal command of the own device and the external command of another device are shared and executed.

  In the above embodiment, the electronic camera 101, the mobile phone 102, the image processing server 104, and the navigation terminal device 106 have been described as main examples as the electronic device 10, but are not limited thereto. The electronic device 10 of the present invention may be a printer, a FAX, a television, a video, or the like as described above as an example of the electronic device, or may be another electronic device such as a computer, a game machine, an electronic dictionary, or an electronic toy. It may be a device.

  The above-described C function platform 16 (251) or the control unit 204 may be realized by dedicated hardware, and is configured by a memory and a CPU (central processing unit). The function may be realized by loading a program for realizing the function into a memory and executing the program.

  Further, a program for realizing the functions of the above-described C function platform 16 (251) or the control unit 204 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system. The processing of each unit described above may be performed by executing. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
