  In the case of a technique in which a digital camera executes a command, whether or not a command transmitted from the digital camera to another electronic device can be selected depends on the function of the digital camera. That is, when a command is to be selected with a digital camera that does not have a function, a procedure such as updating the firmware of the digital camera is required.

  Even in a digital camera having a command selection function, if a new command is to be added, the digital camera firmware needs to be updated in the same manner.

  Furthermore, the file format that can be transmitted by a conventional digital camera is often only an image file, and there are commands that cannot always be transmitted due to limitations of interfaces and hardware resources provided in the digital camera.

A file analysis unit that analyzes a file received from the electronic device via the communication unit using file information registered in the file table, and determines whether the specific file is received;
When the file analysis unit determines that the specific file has been received, the command registered in the command table in association with the file information of the specific file is executed, or the command And a command execution unit that enters an execution standby state.

Further, another invention for solving the above problems is an adapter device capable of communicating with an electronic device,
Communication means for communicating with the electronic device;
A file table for registering file information about a specific file;
A file analysis unit that analyzes a file received from the electronic device via the communication unit using file information registered in the file table, and determines whether the specific file is received;

  ADVANTAGE OF THE INVENTION According to this invention, the adapter apparatus connectable with this electronic device which enables execution of a predetermined command, without updating the firmware of an electronic device can be provided.

  Embodiments of the invention will be described below with reference to the accompanying drawings.

[First embodiment]
First, a first embodiment of the invention will be described. An example of the configuration of the adapter device according to the first embodiment of the invention is shown in FIG. FIG. 1 shows an example of the configuration of an adapter device that is connected to an external electronic device and is intended to expand the functions of the electronic device. Examples of the external electronic device include a digital camera, a digital video camera, a mobile phone, a PDA, and other portable information devices. This also applies to other embodiments thereafter. The adapter device 101 is suitable for use when command information is not included in a file received by the adapter device 101.

  In FIG. 1, a communication interface 102 is a communication interface for enabling communication between an adapter device 101 and an electronic device. The file analysis unit 103 analyzes the file received by the adapter device 101. The command execution unit 104 executes commands stored in the command table. The file table 105 stores file information registered in advance in the adapter device 101. The command table 106 stores command information linked for each file information stored in the file table 105.

  The communication interface 102 may be wired or wireless as long as it can communicate with the electronic device.

  The implementation form of the file analysis unit 103 and the command execution unit 104 is not limited to that shown in FIG. 1 as long as it operates as each function in the adapter device 101. That is, it may be mounted in one CPU, may be mounted with one integrated circuit, or may be mounted as separate integrated circuits.

  The command execution unit 104 selects a command to be executed from the command table 106 based on the analysis result from the file analysis unit 103. If the command can be selected, the connection form between the command execution unit 104, the file analysis unit 103, and the command table 106 is not limited to that shown in FIG.

  The file information registered in the file table 105 may be in any format. That is, it may be changed according to the file type such as a text file or an image file, or the file itself may be registered as file information without depending on the file type. Any format that can compare the received file with the file information registered in the file table 105 when the file analysis unit 103 analyzes the received file may be used.

  The command information registered in the command table 106 may be in any form as long as the command execution unit 104 can interpret it. Further, the command information may include information accompanying a command executed by the command execution unit 104. For example, when the command execution unit 105 has a communication function with an electronic device, the associated information may include the address of the communication destination.

  Next, processing executed in the adapter device 101 will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of processing until the command execution unit 104 executes a command or enters an execution standby state when the adapter device 101 receives a file from the communication interface 102.

  In step S101 in FIG. 2, it is determined whether or not a file has been received via the communication interface 102. If a file is received (“YES” in step S101), the process branches to step S102, and if not received (“NO” in step S101), the process branches to step S105.

  In subsequent step S102, the file analysis unit 103 analyzes the received file. Specifically, an analysis is performed as to whether the received file matches the file information registered in advance in the file table 105. The determination of coincidence here may be under any condition. For example, when the file information registered in the file table 105 is only the file name, the file name of the received file may be compared with the file name of the file information. If CRC information is included in the file information registered in the file table 105, it may be compared. If the file information registered in the file table 105 is all information of the image file, that is, one file, the image matching may be performed for comparison.

  As soon as the analysis of the received file is completed, it is determined in step S103 whether or not the received file matches the file information registered in advance in the file table 105. If the received file matches the file information registered in advance in the file table 105 (“YES” in step S103), the process proceeds to step S104. On the other hand, if they do not match (“NO” in step S103), the process proceeds to step S105.

  In step S <b> 104, command information corresponding to the file for which the match is determined is selected from the command table 106. Then, based on the command information, the command execution unit 104 executes a command, or the command execution unit 104 performs a command execution standby state.

  The command table 106 includes information that links each file information registered in the file table 105 and each command registered in the command table 106. Therefore, the command execution unit 104 can select a command based on the linked information.

  Here, whether the command execution unit 104 executes the selected command immediately or enters the execution standby state of the selected command can be arbitrarily selected based on the command to be executed by the adapter device 101. For example, switching may be performed according to the selected command type, or depending on the purpose of the adapter device 101, it may be fixed to either the execution or execution standby state.

  The timing at which the command execution unit 104 executes a command in the execution standby state may be arbitrary. For example, first, a file indicating “command execution start” is registered in the file table 105, and command information is registered in the command table. Next, when the adapter device 101 receives a file indicating the “command execution start”, the command execution unit 104 may start executing the command in the execution standby state. As another example, when the adapter device 101 has a special user interface such as a button, the user may use the user interface to give a start trigger for a command in an execution standby state. .

  When the command execution unit 104 executes the command, the execution is completed. When the command execution unit 104 is in the command execution standby state, after entering the standby state, a series of processing when the adapter device 101 receives one file ends. To do.

  In step S <b> 105, the adapter apparatus 101 is in a standby state for receiving a file from the communication interface 102. Then, it returns to step S101 and continues a process.

  As described above, according to the present embodiment, the adapter device is connected to an external electronic device, enters a command execution standby state according to a file received from the electronic device, and can execute a command. . Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Second Embodiment]
Next, a second embodiment of the invention will be described. An example of the configuration of the adapter device according to the second embodiment of the invention is shown in FIG. The adapter device 201 shown in FIG. 3 is connected to an electronic device for the same purpose as that of the adapter device 101 of the first embodiment, and aims to expand the function of the electronic device. The adapter device 201 is suitable for use when command information is included in a file received by the adapter device 201.

  The communication interface 102 and the file table 105 in FIG. 3 have the same functions as the communication interface 102 and the file table 105 in FIG. Hereinafter, differences from FIG. 1 will be described.

  The file analysis unit 202 analyzes a file received by the adapter device 101 via the communication interface 102. The file analysis unit 202 performs analysis twice. The first time, an analysis is performed as to whether the received file matches the file information registered in the file table 105. The second time, when the received file matches the file information registered in the file table 105, an analysis is performed as to whether command information is included in the received file.

  When the command analysis unit 203 can extract command information from the file received by the file analysis unit 202, the command execution unit 203 executes a command based on the command information. The implementation of the file analysis unit 202 and the command execution unit 203 is not limited to that shown in FIG. 3 as long as it operates as each function in the adapter device 201, as in the first embodiment.

  A characteristic of the adapter device 201 is that the command table 106 that is necessary in the adapter device 101 is not required due to the above configuration.

  Hereinafter, an example of processing executed in the adapter device 201 corresponding to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of processing until the command execution unit 203 executes a command or enters an execution standby state when a file is received from the communication interface 102 in the adapter device 201.

  In FIG. 4, in step S <b> 201, it is determined whether or not a file has been received via the communication interface 102.

  In step S <b> 201 of FIG. 4, it is determined whether a file has been received via the communication interface 102. If a file has been received (“YES” in step S201), the process branches to step S202, and if not received (“NO” in step S201), the process branches to step S207.

  In subsequent step S202, the file analysis unit 202 performs a first analysis process on the received file. Specifically, the file analysis unit 202 analyzes whether the received file matches the file information registered in advance in the file table 105. Since the specific example of the coincidence determination performed here is the same as that described in step S102 of the first embodiment, the description thereof is omitted here.

  As soon as the analysis of the received file is completed, it is determined in step S203 whether or not the received file matches the file information registered in the file table 105 in advance. If the received file matches the file information registered in advance in the file table 105 (“YES” in step S203), the process proceeds to step S204. On the other hand, if they do not match (“NO” in step S203), the process proceeds to step S207.

  In step S204, the file analysis unit 202 performs a second analysis process on the received file. Specifically, in the second analysis, it is analyzed whether the received file contains information related to a command to be executed by the command execution unit 203.

  As a result of the analysis, if command information is included in the received file (“YES” in step S205), the process proceeds to step S206. On the other hand, if it is not included (“NO” in step S205), the process proceeds to step S207.

  In step S206, based on the command information in the analyzed received file, the command execution unit 203 executes a command or the command execution unit 203 performs a command execution standby state. Here, whether the command execution unit 203 immediately executes the command or enters the execution standby state can be switched by a method similar to that described in step S204 of the first embodiment.

  When the command execution unit 203 executes the command, after completion of the execution, or when in the command execution standby state, after entering the standby state, a series of processing when the adapter device 201 receives one file ends. To do.

  In step S207, the adapter apparatus 201 is in a standby state for receiving a file from the communication interface 102. Then, it returns to step S201 and continues processing.

  As described above, according to the present embodiment, the adapter device can determine whether the file received from the external electronic device matches the file registered in advance in the adapter device. If it matches with the registered file, it is further determined whether or not command information is included in the received file. If command information is included, command execution processing can be performed based on the command information. Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Third embodiment]
Next, a third embodiment of the invention using the adapter device 101 corresponding to the first embodiment will be described. A configuration example of a communication system corresponding to the third embodiment of the invention is shown in FIG. The communication system includes an adapter device 101, an electronic device 304, an access point 306, and network storage servers (NAS) 307 to 309. This embodiment is suitable when the adapter device 101 uploads a plurality of files existing in the storage unit 305 in the electronic device 304 to a NAS connected to the network.

  5, the communication interface 102, the file analysis unit 103, the command execution unit 104, the file table 105, and the command table 106 are the communication interface 102, the file analysis unit 103, the command execution unit 104, the file table 105, and the command table of FIG. This is the same function as 106. For the sake of explanation, the functions and initial conditions of each part are limited as follows.

  The communication interface 102 is a communication interface capable of communicating with an electronic device 304 having a storage unit. The file analysis unit 103 analyzes the file name of the received file. The command execution unit 104 has a wireless communication function, and can wirelessly transmit a file in the storage unit 301 described later.

  In the file table 105, information about three files is registered as an example, and the file names are registered as “AAA.JPG”, “004.JPG”, and “CCC.JPG”, respectively.

  In the command table 106, commands are registered for each of the three files having file names “AAA.JPG”, “004.JPG”, and “CCC.JPG”. Each command is a command for executing transfer of all files stored in the adapter device 101 to different communication destinations. As information for specifying each communication destination, the command table 106 stores an IP address in association with a file name and a command.

  As shown in FIG. 5, it is assumed that the following configuration is attached to the adapter device 101 corresponding to the present embodiment. The storage unit 301 is storage means for temporarily storing a file received by the adapter device 101. The wireless interface 302 is an interface for the adapter device 101 to perform wireless communication with other wireless devices. The antenna 303 is an antenna for transmitting wireless data from the adapter device 101 and receiving wireless data from other wireless devices.

  In FIG. 5, the electronic device 304 is connected via the communication interface 102. The electronic device 304 is configured to automatically send all files in the storage unit 305 when connected to the adapter device 101.

  The storage unit 305 is a storage unit that the electronic device 304 has, and as an example, the file names are “001.JPG”, “002.JPG”, “003.JPG”, and “004.JPG”, respectively. Remember one file. The storage unit 305 can be configured by a semiconductor memory such as a compact flash (registered trademark), for example.

  The access point 306 is an access point for providing the adapter device 101 with a wireless connection with the NAS 307, 308, or 309. The NASs 307 to 309 are network storage servers connected to the access point 306 and provide storage services to devices that can be wirelessly connected to the access point 306.

  Next, an example of processing by the adapter device 101 corresponding to the present embodiment will be described with reference to FIG. The flowchart in FIG. 6 is a flowchart illustrating an example of processing of the adapter device 101 when the adapter device 101 receives a file in the storage unit 305 of the electronic device 304 and uploads the file to the NAS 2 (308).

  In FIG. 6, in step S <b> 301, it is determined whether the adapter device 101 is connected to the electronic device 304 via the communication interface 102. If the adapter device 101 is connected to the electronic device 304 (“YES” in step S301), the process proceeds to step S302. On the other hand, if it is not connected (“NO” in step S301), this process ends.

  In step S302, it is determined whether the adapter apparatus 101 has received all the files stored in the storage unit 305 of the electronic device 304. If all files have been received (“YES” in step S302), the process proceeds to step S308. On the other hand, if an unreceived file remains in the storage unit 305, the process proceeds to step S303.

  In step S <b> 303, it is determined whether the adapter apparatus 101 has received a file from the electronic device 304 via the communication interface 102. If a file is received (“YES” in step S303), the process proceeds to step S304. If not received (“NO” in step S303), the process proceeds to step S309. Step S309 is a standby state for file reception, and returns to step S301 to continue the processing.

  In step S304, the file analysis unit 103 performs an analysis process on the received file. The file analysis unit 103 analyzes whether or not the received file matches file information registered in advance in the file table 105. In the present embodiment, a case where analysis is performed using a file name will be described as an example. However, it is the same as in the first embodiment that determination of matching may be performed by any method.

  In FIG. 5, for example, when the adapter device 101 receives a file having a file name of “004.JPG”, the file has already been registered in the file table 105. It can be determined that they match. On the other hand, for example, when the adapter device 101 receives a file having a file name of “001.JPG”, the file is not registered in the file table 105, so that it does not match the file information registered in advance. Can be judged.

  As a result of such analysis, when it is determined that the received file is registered in advance in the file table 105 (“YES” in step S305), the process proceeds to step S306. On the other hand, if it is not authorized (“NO” in step S305), the process proceeds to step S307.

  In step S306, the command execution unit 104 selects command information corresponding to the file determined to be matched from the command table 106, and enters a command execution standby state based on the command information. In the example of FIG. 5, when the adapter device 101 receives a file having the file name “004.JPG”, a command for wirelessly transmitting all the files in the storage unit 301 to the NAS 2 (308) enters an execution standby state. Become. When the command execution unit 104 shifts to the command execution standby state, the process returns to step S301 to continue the processing.

  Next, in step S307, the file received by the adapter device 101 via the communication interface 102 is stored in the storage unit 301. In the example of FIG. 5, when the adapter device 101 receives a file having file names “001.JPG”, “002.JPG”, and “003.JPG”, the file is stored in the storage unit 301. Then, it returns to step S301 and continues a process.

  Next, in step S308, the command execution unit 104 executes a command that was in the execution standby state. In the example of FIG. 5, all files having file names “001.JPG”, “002.JPG”, and “003.JPG” are stored in the storage unit 301. The command execution unit 104 is in a standby state for executing a command for uploading a file in the storage unit 301 to the NAS 2 (308). Therefore, the command execution unit 104 executes a command for wirelessly transmitting a file having file names “001.JPG”, “002.JPG”, and “003.JPG”. After executing the command, the process ends.

  As described above, according to the present embodiment, a specific file is associated with a command for executing a specific process, and the adapter device can be controlled to execute the specific process in response to reception of the specific file. it can. At that time, the command execution standby state can be held until the command execution condition is satisfied, and when the execution condition is satisfied, the standby state can be shifted to the execution state. Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Fourth Embodiment]
Next, a fourth embodiment of the invention using an adapter device 201 corresponding to the second embodiment will be described. FIG. 7 shows a configuration example of a communication system corresponding to the fourth embodiment of the invention. The communication system includes an adapter device 201, an electronic device 304, an access point 306, and NAS 307 to 309. This embodiment is suitable for a case where the adapter device 201 collectively uploads a plurality of files existing in the storage unit 305 in the electronic device 304 to a storage server connected to the network.

  Thus, the system configuration and application in the present embodiment are substantially the same as the configuration and application in the third embodiment. However, the adapter device 201 corresponding to this embodiment has a different point from the adapter device 101 of the third embodiment. That is, the adapter device 201 is suitable for use when command information is included in a file received by the adapter device 201. Therefore, the adapter device 201 does not need the command table 106 required by the adapter device 101. However, a file analysis unit 202 and a command execution unit 203 are mounted on the adapter device 201 in order to realize function expansion equivalent to that of the adapter device 101.

  In the present embodiment, it is assumed that a file having the file name “004.JPG” among the files in the storage unit 305 includes command information to be executed by the command execution unit 203 in the file. Specifically, the command information includes a command for executing transmission of all files in the storage unit 301 to the NAS 2 (308) and the IP address of the NAS 2 (308) that is the communication destination. .

  Next, an example of processing in the adapter device 201 corresponding to the present embodiment will be described with reference to FIG. The flowchart of FIG. 8 is a flowchart illustrating an example of processing of the adapter device 201 when the adapter device 201 receives a file in the storage unit 305 of the electronic device 304 and uploads the file to the NAS 2 (308).

  In FIG. 8, in step S <b> 401, the adapter device 201 determines whether or not the electronic device 304 is connected via the communication interface 102. If adapter device 201 is connected to electronic device 304 (“YES” in step S401), the process proceeds to step S402. On the other hand, if not connected ("NO" in step S401), this process ends.

  In step S <b> 402, it is determined whether the adapter device 201 has received all the files stored in the storage unit 305 of the electronic device 304. If all files have been received (“YES” in step S402), the process proceeds to step S410. On the other hand, when an unreceived file remains in the storage unit 305 (“NO” in step S402), the process proceeds to step S403.

  In step S <b> 403, it is determined whether the adapter device 201 has received a file from the electronic device 304 via the communication interface 102. If a file is received (“YES” in step S403), the process proceeds to step S404. If not received (“NO” in step S403), the process proceeds to step S413. Step S413 is a standby state for file reception, and returns to step S401 to continue the processing.

  In step S404, the file analysis unit 202 performs a first analysis process on the received file. The file analysis unit 202 analyzes whether or not the received file matches the file information registered in advance in the file table 105. In the present embodiment, a case where analysis is performed using a file name will be described as an example. However, it is the same as in the first embodiment that determination of matching may be performed by any method.

  In FIG. 7, for example, when the adapter device 201 receives a file having a file name “004.JPG”, the file is already registered in the file table 105. It can be determined that they match. On the other hand, for example, when the adapter device 201 receives a file having a file name of “001.JPG”, the file is not registered in the file table 105, so that it does not match the file information registered in advance. Can be judged.

  As a result of such analysis, when it is determined that the received file is registered in advance in the file table 105 (“YES” in step S405), the process proceeds to step S406. On the other hand, when it is not certified (“NO” in step S405), the process proceeds to step S409.

  In step S406, the file analysis unit 202 performs a second analysis process on the received file. The file analysis unit 202 analyzes whether or not command information to be executed by the command execution unit 203 is included in the received file.

  If the command information is not included as a result of the second analysis of the received file (“NO” in step S407), the process proceeds to step S411. Step S411 is a file reception standby state, and the process returns to step S401 to continue the processing. On the other hand, if command information is included (“YES” in step S407), the process proceeds to step S408. At that time, the command information may be extracted from the received file and passed to the command execution unit 203. In the case of FIG. 7, when the adapter device 201 receives a file having the file name “004.JPG”, the process proceeds to step S408. In step S408, the command execution unit 203 shifts to a command execution standby state based on the command information in the received file.

  In the example of FIG. 7 of the present embodiment, when the adapter device 201 receives a file having the file name “004.JPG”, execution of a command for wirelessly transmitting all the files in the storage unit 301 to the NAS 2 (308). It will be in a standby state. When the command execution unit 203 shifts to the command execution standby state, the process returns to step S401 and continues processing.

  Next, in step S <b> 409, the file received by the adapter device 201 via the communication interface 102 is stored in the storage unit 301. In the example of FIG. 7, when the adapter device 101 receives a file having file names “001.JPG”, “002.JPG”, and “003.JPG”, the file is stored in the storage unit 301. Then, it returns to step S401 and continues a process.

  Next, in step S410, the command execution unit 203 performs a command execution process in the execution standby state. In the example of FIG. 7, all files having file names “001.JPG”, “002.JPG”, and “003.JPG” are stored in the storage unit 301. The command execution unit 203 is in a standby state for executing a command for uploading a file in the storage unit 301 to the NAS 2 (308). Therefore, the command execution unit 203 executes a command for wirelessly transmitting a file having file names “001.JPG”, “002.JPG”, and “003.JPG”. After executing the command, the process ends.

  As described above, according to the present embodiment, command information for executing a specific process is included in a specific file, and when the specific file is received, the command information is extracted and the specific process is executed. The adapter device can be controlled. At that time, the command execution standby state can be held until the command execution condition is satisfied, and when the execution condition is satisfied, the standby state can be shifted to the execution state. Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Fifth Embodiment]
Next, a fifth embodiment of the invention using the adapter device 101 corresponding to the first embodiment of the invention will be described. A configuration example of a communication system corresponding to the fifth embodiment of the invention is shown in FIG. The communication system includes an adapter device 101, an electronic device 501, an access point 306, a printer 502, a NAS 503, and a display 504. The present embodiment is suitable for a case where a transmission destination is selected one by one for a file stored in the storage unit 305 in the electronic device 501 and transmitted.

  9, the communication interface 102, the file analysis unit 103, the command execution unit 104, the file table 105, and the command table 106 in the adapter device 101 perform the same functions as the corresponding elements in FIG. However, in this embodiment, the function and initial conditions of each part are limited as follows.

  The communication interface 102 is a communication interface that can communicate with the electronic device 501 having the storage unit 305. The file analysis unit 103 analyzes the file name of the received file. The command execution unit 104 has a wireless communication function and can wirelessly transmit a file received from the electronic device 501. Information related to three files is registered in the file table 105, and “004.JPG”, “005.JPG”, and “006.JPG” are registered as file names, respectively.

  Commands to be executed are assigned to the three files having the file names “004.JPG”, “005.JPG”, and “006.JPG”, respectively, and the commands are registered in the command table 106. Each command is a command for executing a wireless communication function, but has a different communication destination.

  The command assigned to the file “004.JPG” is a command for executing wireless transmission to the printer 502. In FIG. 9, “PRINT” indicates that a file is assigned to this command. The command assigned to the file “005.JPG” is a command for executing wireless transmission to the NAS 503. In FIG. 9, “NAS” indicates that a file is assigned to this command. The command assigned to the file “006.JPG” is a command for executing wireless transmission to the display 504. In FIG. 9, “DISP” indicates that a file is assigned to this command. As information for specifying each communication destination, the command table 106 stores an IP address in association with a file name and a command.

  Further, it is assumed that the adapter device 101 has the following functions for explanation.

  A wireless interface 302 indicates an interface for performing wireless communication between another wireless device and the adapter device 101. It has the same function as the wireless interface 302 of the third embodiment. The antenna 303 is an antenna for transmitting wireless data from the adapter device 101 and receiving wireless data from other wireless devices. It has the same function as the antenna 303 of the third embodiment.

  In the present embodiment, since the storage unit 301 may not be provided, the storage unit 301 is not illustrated in FIG.

  Furthermore, in order to explain the operation of the adapter device 101 with other electronic devices, the following external devices are added. The electronic device 501 is connected via the communication interface 102. The electronic device 501 is configured to automatically send all files in the storage unit 305 when connected to the adapter device 101.

  The storage unit 305 is a storage unit that the electronic device 501 has. As an example, the storage unit 305 has file names “001.JPG”, “002.JPG”, “003.JPG”, “004.JPG”, “005.JPG”, and “006.JPG”, respectively. One file is stored. The storage unit 305 can be configured by a semiconductor memory such as a compact flash (registered trademark), for example.

  The access point 306 has the same function as the access point 306 of the third embodiment.

  The printer 502 is a printing apparatus and has a function of printing out data received via the access point 306. The printing method employed by the printer 502 is irrelevant to the essential matters of the present invention and is not particularly limited. The NAS 503 is a network storage server connected to the access point 306 and provides a storage service to a device that can be wirelessly connected to the access point 306. The display 504 is a display device and has a function of displaying data received via the access point 306. The display device employed by the display 504 is not particularly limited because it is irrelevant to the essential matters of the present invention.

  Next, an example of processing in the adapter device 101 corresponding to the present embodiment will be described with reference to FIG. The flowchart in FIG. 10 is a flowchart illustrating an example of processing of the adapter device 101 when the adapter device 101 receives a file in the storage unit 305 of the electronic device 501 and wirelessly transmits the file to various devices.

  In FIG. 10, in step S <b> 501, it is determined whether the adapter device 101 is connected to the electronic device 501 via the communication interface 102. If the adapter device 101 is connected to the electronic device 501 (“YES” in step S501), the process proceeds to step S502. On the other hand, if it is not connected (“NO” in step S501), this process ends.

  In step S502, it is determined whether the adapter device 101 has received a file stored in the storage unit 305 of the electronic device 501. If a file is received (“YES” in step S502), the process proceeds to step S503. On the other hand, when the file is not received (“NO” in step S502), the process proceeds to step S508. Step S508 is a file reception standby state, and the process returns to step S501 to continue the processing.

  In step S503, the file analysis unit 103 performs analysis processing on the received file. The file analysis unit 103 analyzes whether or not the received file matches file information registered in advance in the file table 105. In the present embodiment, a case where analysis is performed using a file name will be described as an example. However, it is the same as in the first embodiment that determination of matching may be performed by any method.

  In FIG. 9, for example, when a file having a file name of “004.JPG”, “005.JPG”, or “006.JPG” is received, the file is already registered in the file table 105, and thus registered in advance. It can be determined that the file information matches. On the other hand, for example, when a file having a file name of “001.JPG”, “002.JPG”, or “003.JPG” is received, the file is not registered in the file table 105, and thus file information registered in advance. Can be determined not to match.

  As a result of such analysis, if the received file matches the file information registered in advance in the file table 105 (“YES” in step S504), the process proceeds to step S505. On the other hand, if they do not match (“NO” in step S504), the process proceeds to step S506.

  In step S505, the command execution unit 104 shifts to a command execution standby state corresponding to the received file for which the match determination has been made. In the example of the fifth embodiment shown in FIG. 9, when a file having a file name of “004.JPG”, “005.JPG”, or “006.JPG” is received, a command execution standby state corresponding to each image is received. become. For example, when a file with a file name of “004.JPG” is received, execution of a command for transmitting data to the printer 502 is awaited. Then, it returns to step S501 and continues a process.

  In step S506, it is determined whether there is a command in an execution standby state. If there is no execution standby command (“NO” in step S506), the process proceeds to step S509. Step S508 is in a standby state, and the process returns to step S501 and continues. On the other hand, if there is a command waiting for execution, the process proceeds to step S507.

  In step S507, the command execution unit 104 executes the command waiting for execution with the received file as an execution target. Here, for example, it is assumed that the command execution unit 104 is in a command execution standby state corresponding to a file having a file name “004.JPG”. In this case, when the adapter device 101 receives a file having a file name “001.JPG”, the command is executed, and the file having the file name “001.JPG” is wirelessly transmitted to the printer 502. Thereafter, the process returns to step S501.

  Note that whether or not to place the command execution unit 104 in the command execution standby state can be arbitrarily set even after the command execution unit 104 executes the command in step S507. For example, the execution standby state of the same command can be continued until a file corresponding to a command different from the command in the execution standby state is received from the electronic device 501. On the other hand, the execution standby state may be canceled each time a command is executed for one file.

  As described above, according to the present embodiment, command information for executing a specific process can be assigned to a specific file, and a corresponding command can be placed in an execution standby state in response to reception of the specific file. When a command execution target file is received during the execution standby state, the command for the received file can be executed by switching from the execution standby state to the execution state. Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Sixth Embodiment]
Next, a sixth embodiment of the invention using an adapter device 201 corresponding to the second embodiment of the invention will be described. A configuration example of a communication system corresponding to the sixth embodiment of the invention is shown in FIG. The communication system includes an adapter device 201, an electronic device 501, an access point 306, a printer 502, a NAS 503, and a display 504. The present embodiment is suitable for a case where a transmission destination is selected one by one for a file stored in the storage unit 305 in the electronic device 501 and transmitted.

  As described above, the system configuration and application in the present embodiment are substantially the same as those in the fifth embodiment. However, the adapter device 201 corresponding to this embodiment has a different point from the adapter device 101 of the fifth embodiment. That is, the adapter device 201 is suitable for use when command information is included in a file received by the adapter device 201. Therefore, the adapter device 201 does not need the command table 106 required by the adapter device 101. However, a file analysis unit 202 and a command execution unit 203 are mounted on the adapter device 201 in order to realize function expansion equivalent to that of the adapter device 101.

  In the present embodiment, among the files in the storage unit 305, files having file names “004.JPG”, “005.JPG”, and “006.JPG” should be executed by the command execution unit 203 in the file. Command information shall be included. That is, a file having a file name “004.JPG” includes a command indicating file transmission to the printer 502 and the IP address of the printer 502 in the file. In FIG. 11, this is indicated by the notation “PRINT”. A file having a file name “005.JPG” includes a command indicating file transmission to the NAS (503) and the IP address of the NAS (503) in the file. In FIG. 11, this is indicated by the notation “NAS”. Further, it is assumed that a file having a file name “006.JPG” includes a command indicating file transmission to DISPLAY (504) and an IP address of DISPLAY (504) in the file. In FIG. 11, this is indicated by the notation “DISP”.

  Next, an example of processing in the adapter device 201 corresponding to the present embodiment will be described with reference to FIG. The flowchart of FIG. 12 is a flowchart illustrating an example of processing of the adapter device 201 when the adapter device 201 receives a file in the storage unit 305 of the electronic device 501 and wirelessly transmits the file to various devices.

  In FIG. 12, in step S <b> 601, the adapter apparatus 201 determines whether or not the electronic apparatus 501 is connected via the communication interface 102. If the adapter device 201 is connected to the electronic device 501 (“YES” in step S601), the process proceeds to step S602. On the other hand, if it is not connected (“NO” in step S601), this process ends.

  In step S602, it is determined whether the adapter device 201 has received a file stored in the storage unit 305 of the electronic device 501. If a file is received (“YES” in step S602), the process proceeds to step S603. On the other hand, when the file is not received (“NO” in step S602), the process proceeds to step S610. Step S610 is a file reception standby state, and the process returns to step S601 to continue the processing.

  In step S603, the file analysis unit 202 performs a first analysis process on the received file. The file analysis unit 202 analyzes whether or not the received file matches the file information registered in advance in the file table 105. In the present embodiment, a case where analysis is performed using a file name will be described as an example. However, it is the same as in the first embodiment that determination of matching may be performed by any method.

  In FIG. 11, for example, when a file having a file name of “004.JPG”, “005.JPG”, or “006.JPG” is received, the file is already registered in the file table 105, and thus registered in advance. It can be determined that the file information matches. On the other hand, for example, when a file having a file name of “001.JPG”, “002.JPG”, or “003.JPG” is received, the file is not registered in the file table 105, and thus file information registered in advance. Can be determined not to match.

  As a result of such analysis, if the received file matches the file information registered in advance in the file table 105 (“YES” in step S604), the process proceeds to step S605. On the other hand, if they do not match (“NO” in step S604), the process proceeds to step S608.

  In step S605, the file analysis unit 202 performs a second analysis process on the received file. The file analysis unit 202 analyzes whether or not command information to be executed by the command execution unit 203 is included in the received file.

  If the command information is not included as a result of the second analysis of the received file (“NO” in step S606), the process proceeds to step S611. Step S611 is a file reception standby state, and the process returns to step S601 to continue the processing. On the other hand, if command information is included (“YES” in step S606), the process proceeds to step S607.

  In the case of FIG. 11, when the adapter apparatus 201 receives a file having file names “004.JPG”, “005.JPG”, and “006.JPG”, the process proceeds to step S607. In step S607, the command execution unit 203 shifts to a command execution standby state based on the command information in the received file. For example, when a file with a file name of “004.JPG” is received, execution of a command for transmitting data to the printer 502 is awaited. Then, it returns to step S601 and continues the process.

  In step S608, it is determined whether there is a command waiting for execution. If there is no execution standby command (“NO” in step S608), the process proceeds to step S611. Step S611 is in a standby state, and the process returns to step S601 and continues. On the other hand, if there is a command waiting for execution, the process proceeds to step S609.

  In step S <b> 609, the command execution unit 203 executes the command that has been waiting to be executed with the received file as an execution target. Here, for example, it is assumed that the command execution unit 203 is in a command execution standby state corresponding to a file having a file name “004.JPG”. In this case, when the adapter device 201 receives a file having the file name “001.JPG”, the command is executed, and the file having the file name “001.JPG” is wirelessly transmitted to the printer 502. Thereafter, the process returns to step S601.

  Note that whether or not to place the command execution unit 203 in the command execution standby state can be arbitrarily set after the command execution unit 203 executes the command in step S609. For example, the execution standby state of the same command can be continued until a file corresponding to a command different from the command in the execution standby state is received from the electronic device 501. On the other hand, the execution standby state may be canceled each time a command is executed for one file.

  As described above, according to the present embodiment, command information for executing a specific process is included in a specific file, and when the specific file is received, the command information is extracted and placed in a command execution standby state. Can do. When a command execution target file is received during the execution standby state, the command for the received file can be executed by switching from the execution standby state to the execution state. Thereby, the function of the electronic device connected to the adapter device can be expanded.

[Seventh Embodiment]
Next, a seventh embodiment of the invention relating to a process of writing a specific file from the adapter device to the electronic device, which is a premise of the first to seventh embodiments, will be described. FIG. 13 shows the configuration of an adapter device according to the seventh embodiment of the invention. The function of the adapter device 101 described in the present embodiment is suitable for writing a file registered in the file table 105 to the electronic device 501 having the storage unit 305.

  The components of the adapter device 101 shown in FIG. 13 are the same as those of the adapter device 101 shown in FIG. As shown in FIG. 13, in this embodiment, three files having file names “001.JPG”, “BBB.JPG”, and “CCC.JPG” are registered in the file table 105. In the command table 106, “registered file write”, “command 2”, and “command 3” for three files having file names “001.JPG”, “BBB.JPG”, and “CCC.JPG” are stored. Are registered respectively.

  The electronic device 501 includes a storage unit 305 and can be configured by a semiconductor memory such as a compact flash (registered trademark), for example. The electronic device 501 also has a function of sending out the files in the storage unit 305 one by one. It is assumed that files having file names “001.JPG”, “002.JPG”, “003.JPG”, and “004.JPG” are registered in the storage unit 305.

  Next, an example of processing in the adapter device 101 corresponding to the present embodiment will be described with reference to FIG. The flowchart of FIG. 14 is a flowchart illustrating an example of processing of the adapter device 101 when the adapter device 101 writes a file registered in the file table 105 to the storage unit 305 of the electronic device 501.

  In FIG. 14, in step S <b> 701, it is determined whether the adapter device 101 is connected to the electronic device 501 through the communication interface 102. If the adapter device 101 is connected to the electronic device 501 (“YES” in step S701), the process proceeds to step S702. On the other hand, if not connected (“NO” in step S701), the process ends.

  In step S702, it is determined whether the adapter apparatus 101 has received an input of a predetermined operation from the user. The predetermined operation is an operation serving as a trigger for writing a file registered in the file table 105 in the storage unit 305 of the electronic device 501. This trigger operation may be any operation. For example, if the adapter device 101 is provided with a user interface (such as operation buttons), it may be used. Hereinafter, a case where an operation for transmitting a file having the file name “001.JPG” from the electronic device 501 to the adapter device 101 is performed as the predetermined operation will be described.

  The file name “001.JPG” is registered in the file table 105 of the adapter device 101. In the command table 106, a file name “001.JPG” and a command for executing writing of a registered file are linked. Therefore, when the predetermined operation is performed, the command execution unit 104 writes the registered file. The processing contents described below are performed by executing the command.

  If an input of a predetermined operation is received and a file “001.JPG” is received as a result (“YES” in step S702), the process proceeds to step S704. On the other hand, if the input of the predetermined operation is not accepted and the file “001.JPG” is not received (“NO” in step S702), the process proceeds to step S703. Step S703 is a standby state, and the process returns to step S701 to continue the processing.

  In step S <b> 704, the adapter apparatus 101 performs processing for confirming the number of files to be written to the storage unit 305 and the total file size among the files registered in the file table 105. Here, it is assumed that the number of files is “Nf” and the total file size is “Sf”.

  In the example of the present embodiment shown in FIG. 13, “001.JPG” has already been written in the storage unit 305, and “001.JPG” is received and the corresponding command is executed based on the predetermined operation. Yes. Therefore, when selecting a file to be written in step S704, “001.JPG” can be excluded and the remaining “BBB.JPG” and “CCC.JP” can be used as files to be written. In this case, Nf = 2. The total file size Sf is the total value of the file sizes of “BBB.JPG” and “CCC.JP”.

  Next, in step S <b> 705, the adapter apparatus 101 performs status confirmation processing for the storage unit 305. Specifically, the adapter device 101 inquires of the electronic device 501 about the file name of the file existing in the storage unit 305 and the free space (Va) of the storage unit as confirmation items. By confirming the file name in this way, it is possible to prevent duplication of the file name when the adapter device 101 writes the file to the storage unit 305 later. Furthermore, since the format of the file name can be matched with that of the electronic device 501, malfunction of the electronic device 501 can be prevented.

  Next, in step S706, the adapter apparatus 101 determines whether or not there is a free capacity for the file to be written in the storage unit 305 based on the free capacity Va confirmed by the electronic device 501 and the file size Sf to be written. To do. If Va is greater than or equal to Sf, it is determined that there is free space in the storage unit 305 (“YES” in step S706), and the process proceeds to step S707. On the other hand, if Va is less than Sf and there is no free space (“NO” in step S706), this process ends.

  In step S707, it is determined whether or not there is an empty file name for the number Nf of files to be written by the adapter apparatus 101 at the head of the file group stored in the storage unit 305.

  For example, it is assumed that the file names that the file stored in the electronic device 305 should have are “001.JPG” to “999.JPG” in ascending order. At this time, it is assumed that the file names of the files actually stored in the storage unit 305 are “004.JPG”, “005.JPG”, and “006.JPG”. In this case, among the file names of the file groups stored in the storage unit 305, the free file names positioned at the top in the ascending order are “001.JPG”, “002.JPG”, and “003.JPG”. The number of file names is three.

  If there is an empty file name for Nf (“YES” in step S707), the process proceeds to step S708. On the other hand, if there are no free file names for Nf (“NO” in step S707), the process proceeds to step S709.

  In the present embodiment, the storage unit 305 stores “001.JPG” to “004.JPG”. Therefore, the number of empty file names is “0”.

  In step S <b> 708, the adapter apparatus 101 performs a process of writing a file to be written in the storage unit 305 among the files registered in the file table 105 in the storage unit 305. Here, since the file name located at the beginning of the file name of the file group stored in advance in the storage unit 305 is empty, the adapter device 101 writes the file with the file name located at the beginning. I do. For example, when there are three files to be written and the file names “001.JPG”, “002.JPG”, and “003.JPG” are empty file names, the files for writing the three files The name becomes the empty file name. Here, when writing the file to the storage unit 305, the file is written with a deletion prohibition flag so that the file written by the electronic device 305 is not erased. Thereafter, the process proceeds to step S711.

Next, in step S709, it is determined whether there is an empty file name corresponding to the number Nf of files to be written by the adapter apparatus 101 at the end of the file group stored in the storage unit 305.
For example, the file name that the file stored in the electronic device 305 should have is “001.JPG” to “999.JPG”, and the file name of the actually stored file is “001.JPG”. Suppose that it is up to "006.JPG". In this case, the empty file name at the end of the file group stored in the storage unit 305 is changed from “007.JPG” to “999.JPG”, and the number of empty file names is 993.

  If there is an empty file name at the end (“YES” in step S709), the process proceeds to step S710. On the other hand, if there is no empty file name at the end (“NO” in step S709), the process proceeds to step S710.

  In step S <b> 710, the adapter apparatus 101 performs a process of writing a file to be written to the storage unit 305 among the files registered in the file table 105 in the storage unit 305. Here, since there is a vacancy in the file name at the end of the file name of the file group stored in the storage unit 305, the adapter apparatus 101 writes the file with the file name at the end. Further, when writing a file to the storage unit 305, the file is written with a deletion prohibition flag so that the file written by the electronic device 305 is not erased. After writing the file, the process proceeds to step S711.

  In step S 711, the file name of the file registered in the file table 105 is changed to the file name used when writing to the storage unit 305. Accordingly, when the adapter device 101 receives a file written in the storage unit 305, the file analysis unit 103 can compare with the registration information of the file table 105 based on the file name.

  In the example of this embodiment shown in FIG. 13, the number of files registered in the file table 105 is three. However, the file having the file name “001.JPG” is already stored in the storage unit 305. Therefore, the files to be written are files having file names “BBB.JPG” and “CCC.JP”. Therefore, the file names used when writing to the storage unit 305 are replaced with the old file names of “BBB.JPG” and “CCC.JP”. In FIG. 13, since “001.JPG” to “004.JPG” are already stored, the file names “005.JPG” and “006.JPG” are used. Therefore, the file names “BBB.JPG” and “CCC.JP” are replaced with the file names “005.JPG” and “006.JPG”.

  Thereafter, in step S712, the file name linked to the command in the information in the command table 106 is updated with the file name of the file written in the storage unit 305. Accordingly, when the adapter device 101 receives a file written in the storage unit 305, the command execution unit 104 can select a command to be executed based on the file name. When the update of the link information is completed in this way, this process ends.

  The above is the processing flow when the adapter device 101 writes the file registered in the file table 105 to the storage unit 305. FIG. 15 shows the state of the adapter device 101 and the electronic device 501 when a series of processing ends.

  In FIG. 15, files “005.JPG” and “006.JPG” are written in the storage unit 305, and a deletion prohibition flag is set. Although “001.JPG” has no deletion flag, it may be set up. If it becomes unnecessary after the writing of the file from the adapter device 101 is completed, it is not necessary to set the deletion prohibition flag. In the file table 105, file names “005.JPG” and “006.JPG” are registered. Further, in the command table 106, the command 2 is linked to “005.JPG”, and the command 3 is linked to “006.JPG”.

  Thus, when the adapter device 101 receives the file “005.JPG” or “006.JPG” from the electronic device 501, the command table 2 or the command 3 is executed using the file table 105 and the command table 106. Can do.

  Note that the file name when initially registered in the file table 105 is preferably a file name that is named according to a rule different from the file name selection rule applied to the file stored in the storage unit 305. Specifically, when any of 999 types from “001.JPG” to “999.JPG” is applied to the file stored in the storage unit 305 as described above, it is out of this rule. Any file name can be used. As a result, a file that has not been written to the storage unit 305 can be easily identified.

  In the present embodiment, the adapter device 101 having the command table 106 has been described. However, the present embodiment can also be applied to the adapter device 201 that does not have the command table 106.

  Specifically, in the case of the adapter device 201, command information may be included in a file to be written in the storage unit 305, and the file name in the file table 105 may be changed to the file name used for writing when the writing is completed.
