Description

  The present invention relates to a communication device, and more particularly, to a communication device that can transmit image data by an operation from a digital camera.

With the advancement of digital home appliance technology, it has become possible to easily print images taken by individuals using a digital still camera (DSC), a printer, or a personal computer (PC).
In particular, if the device is compatible with a direct print function in which a DSC and a printer are directly connected via an interface such as a USB (Universal Serial Bus) (for example, see Non-Patent Document 1) or the like, a PC is not owned. Since printing is possible even for a user, photo printing by an individual is becoming more familiar.

  Here, there are several methods for the direct print function. As typical examples, PictBridge (registered trademark) standardized by the Camera & Imaging Products Association (CIPA) (see, for example, Patent Document 1 and Non-Patent Document 2). Is mentioned.

However, conventionally, after data is temporarily stored in a data transmission device such as a PC, a wireless terminal is activated from the data transmission device to transmit data such as an image. In some cases, the convenience of the user of the wireless terminal becomes insufficient in that data is transmitted through the terminal.
For example, in a municipal digital mobile communication system (see Non-Patent Document 3) and a narrow-band digital communication system (see Non-Patent Document 4), a digital camera function is usually not added to a wireless terminal. In the case of transmitting the image data, the image data acquired by the digital camera is temporarily stored in a PC or the like, and the image data is transmitted from the PC via the wireless terminal, which is inconvenient for the user.
The present invention has been made in view of such a conventional situation, and an object thereof is to provide a communication apparatus capable of transmitting image data by an operation from a digital camera.

In order to achieve the above object, in the present invention, a communication apparatus for communicating data has the following configuration.
That is, the storage means stores image data. The connecting means connects to the digital camera. The connection communication means communicates with the digital camera connected by the connection means. The communication means performs communication via a line different from the connection by the connection means. The setting means has one or both of a function of presetting a communication partner by the communication means or a function of setting by designation. In response to the print request output from the digital camera connected by the connection means being received by the connection communication means, the control means receives image data output from the digital camera and stores it in the storage means. When the writing is completed, a print completion notification is transmitted to the digital camera by the connection communication unit, and at the same time, stored in the storage unit to the destination set by the setting unit The transmitted image data is transmitted by the communication means.
Therefore, in the communication device, image data can be transmitted by an operation from the digital camera. For example, the convenience of the user who uses the communication device can be improved.

Here, various storage means may be used.
Various digital cameras, connection means, and connection communication means may be used. The digital camera is, for example, a digital still camera or a digital video camera, and includes those provided as functions in a mobile phone or the like. In the case of a digital video camera, still image data extracted from a captured moving image is image data of the present invention.
Various types of communication means and lines used by the communication means may be used. For example, as a line, a wireless line may be used, or a wired line may be used.

Moreover, various things may be used as the other party of communication by a communication means.
Moreover, as a setting means, for example, you may have only one of the function which presets the other party of communication, and the function which sets the other party of communication by designation | designated, or you may have both. In the function of setting the communication partner in advance, for example, identification information such as a telephone number of the communication partner is stored in advance in a memory or the like. Further, in the function of setting the communication partner by designation, for example, in response to an operation input by a user (person) or an input from an external device, identification information such as a telephone number of the communication partner is received and stored in a memory or the like. To set.

Further, in the digital camera, for example, in response to an operation input by a user (person), a print request is output, image data related to the print request is output, and a print completion notification is received.
Various timings may be used as the timing at which the communication means transmits the image data stored in the storage means to the counterpart set by the setting means by the control means. Arbitrary timing after the completion of the writing in which the image data output from the camera is received and stored in the storage means may be used, or the connection communication means notifies the digital camera of the completion of printing. Any timing after transmission may be used, or if practically effective, the image data output from the digital camera is received, written in the storage means, and stored before the writing is completed. Arbitrary timings may be used. In this case, the image data written in the storage means is also used. There is it is possible to sequentially transmitted.

  As described above, according to the communication device according to the present invention, image data can be transmitted by an operation from a digital camera, and, for example, convenience for a user who uses the communication device can be improved.

FIG. 3 shows an example of characteristic functions of the wireless terminal device 21 of this example.
The wireless terminal device 21 of this example includes, as characteristic functions, a USB connection function 51, a pictobridge function 52, a virtual buffer output function 53, a virtual buffer 54, a file transfer function 55, an MMI (Man Machine Interface) function 56, a telephone A number holding function 57 and a wireless communication function 58 are provided.

Here, in this example, these functions are realized using a software program. The software program and data are stored in the nonvolatile memory 5 and the RAM 6 and processed by the CPU 4.
The virtual buffer 54 is arranged on the RAM 6 or a memory (not shown) of the CPU 4. The telephone number holding function 57 is arranged on the nonvolatile memory 5 and / or the RAM 6.

In the table of this example, operation mode information, transmission destination setting information, transmission destination telephone number 1 information, transmission destination telephone number 2 information, transmission destination telephone number history 1 information, transmission destination telephone number history 2 information Is retained.

  Here, when automatic (for example, 0) is set as the operation mode, the file transfer function 55 automatically transmits to the transmission destination with reference to the transmission destination setting information. On the other hand, when manual (for example, 1) is set as the operation mode, the destination telephone number 1, the destination telephone number 2, the destination telephone number history 1, A transmission destination is selected from the transmission destination telephone number history 2, and the apparatus transmits in response thereto.

Further, as the destination setting information, for example, either a value having the destination telephone number 1 as the destination (for example, 1) or a value having the destination telephone number 2 as the destination (for example, 2) Is set.
The information on the destination telephone number 1 and the information on the destination telephone number 2 are set as fixed-length character strings.
The information on the destination telephone number history 1 and the information on the destination telephone number history 2 are set as fixed-length character strings and are updated based on the communication status (transmission status) of the apparatus.
Note that the content of the table of the telephone number holding function 57 is changed via the MMI function 56 according to the operation content input to the input unit 8 by the user, for example.

With reference to FIG. 5, an example of a processing sequence at the time of Pictbridge printing operation in the DSC 22 is shown.
Normally, when the PictBridge function is installed in the printer, the received data is printed out after the data transfer is completed. In this example, the virtual buffer output function 53 outputs the data to the virtual buffer 54.

  Specifically, in the wireless terminal device 21 of this example, the connection request (T1) signal output from the DSC 22 is received by the USB connection function 51 via the USBIF 12, and the USB connection function 51 is connected to the DSC 22 (T2). ) Signal is output. Thereafter, for example, when an operation (T3) instructing printing by the user is performed in the DSC 22, a print request (T4) signal is output from the DSC 22 and received by the PictBridge function 52 via the USBIF 12 and the USB connection function 51. .

  Then, the PictBridge function 52 outputs a print request (T5) signal to the virtual buffer output function 53, and the virtual buffer output function 53 connects the print request permission (T6) signal to the USB in response to receiving the signal. The data is output to the DSC 22 via the function 51 and the USBIF 12. Thereby, transmission (transfer) processing (T7) of data to be printed is performed from the DSC 22 to the virtual buffer output function 53 via the USBIF 12 and the USB connection function 51.

  The virtual buffer output function 53 executes a process (T8) for writing the data received from the DSC 22 to the virtual buffer 54, and the virtual buffer 54 outputs a data write completion (T9) notification to the virtual buffer output function 53. As a result, the virtual buffer output function 53 outputs a print completion notification (T10) signal to the DSC 22 via the USB connection function 51 and the USBIF 12.

With reference to FIG. 6, an example of a transmission processing sequence of the file transfer function 55 is shown.
In this example, the file transfer function 55 monitors whether there is data in the virtual buffer 54 by a polling method (other methods may be used), and if there is data in the virtual buffer 54, With reference to the operation mode of the telephone number holding function 57, for example, when the operation mode is automatic, information is transmitted through the wireless communication function 58 using the information of the telephone number holding function 57.

Further, in this example, after the transmission of wireless data is completed, the file transfer function 55 disconnects via the wireless communication function 58, updates the history of the telephone number holding function 57, and wirelessly transmits via the MMI function 56. Displays the completion of data transmission.
Further, in this example, when the wireless data transmission is abnormally disconnected, the file transfer function 55 displays a re-transmission of the wireless data transmission via the MMI function 56, and a predetermined number of retries, Repeat the process from outgoing. If an abnormality occurs even after repeating the number of retries, that effect is displayed via the MMI function 56, and the process is terminated.

Specifically, in the wireless terminal device 21 of this example, for example, when an input operation (T21) by a user instructing to update the telephone number holding function 57 is received by the MMI function 56, the MMI function 56 uses the telephone number. The held content (stored content) of the holding function 57 is updated (T22).
Further, the file transfer function 55 outputs a polling (T23) signal to the virtual buffer 54. If there is no data, the virtual buffer 54 outputs a signal indicating no data (T24) to the file transfer function 55.

  On the other hand, the file transfer function 55 outputs a polling (T25) signal to the virtual buffer 54. If there is data, the virtual buffer 54 outputs a signal indicating the presence of data (T26) to the file transfer function 55. . In this case, the file transfer function 55 refers to the operation mode of the telephone number holding function 57 (T27). For example, when the operation mode is automatic, the file transfer function 55 reads the data stored in the virtual buffer 54 (T28). Then, using the information on the telephone number held in the telephone number holding function 57, a call is made to another apparatus (for example, the data transmission apparatus 34) having the telephone number via the wireless communication function 58 ( T29). As a result, wireless data transmission (T30) is performed from the file transfer function 55 via the wireless communication function 58.

  When the transmission of the wireless data is completed (normally), the file transfer function 55 disconnects the wireless communication via the wireless communication function 58 (T31), and updates the history of the telephone number holding function 57 (T32). ), A screen display for notifying the user of the completion of transmission of wireless data via the MMI function 56 is performed (T33).

  On the other hand, when wireless data transmission (T34) is performed from the file transfer function 55 via the wireless communication function 58, the wireless data transmission is abnormally disconnected, and a signal indicating abnormal disconnection (T35) is transmitted from the wireless communication function 58. When output to the file transfer function 55, the file transfer function 55 displays a screen for notifying the user that the wireless data transmission is to be retransmitted via the MMI function 56 (T36). ) For example, the process is repeated from the transmission (T37) for a predetermined number of retries (T38). If an error occurs even after repeating the number of retries, the file transfer function 55 displays a screen for notifying the user via the MMI function 56 and ends the process.

Here, in this example, the case where the operation mode is automatic is shown. However, for example, when the operation mode is manual, the transmission destination is manually selected by the user, and other processing operations are the same as in this example. It is the same.
Further, in this example, the case where automatic retry (retransmission) is performed by the file transfer function 55 is shown, but for example, the retry (retransmission) is performed by the file transfer function 55 in response to a manual instruction from the user. May be. Furthermore, if the wireless communication function 58 determines that the wireless state is normal (for example, the area has changed from outside the service area), the file transfer function 55 may retry (retransmit).

Referring to FIG. 7, an example of a processing sequence at the time of print request rejection is shown.
In this example, when there is a print request from the DSC 22, the virtual buffer output function 53 requests the DSC 22 to notify the data size, and acquires data size information. The virtual buffer output function 53 determines whether or not the data size is greater than or equal to a preset threshold (or exceeds the threshold). If the data size is greater than or equal to the threshold (or exceeds the threshold), the virtual buffer output function 53 The print request reject is sent, and the subsequent processing is not performed.

  Specifically, in the wireless terminal device 21 of this example, the connection request (T41) signal output from the DSC 22 is received by the USB connection function 51 via the USBIF 12, and the USB connection function 51 is connected to the DSC 22 (T42). ) Signal is output. Thereafter, when the DSC 22 performs an operation for instructing printing, for example, a print request (T43) signal is output from the DSC 22 and received by the PictBridge function 52 via the USBIF 12 and the USB connection function 51.

  Then, the PictBridge function 52 outputs a print request (T44) signal to the virtual buffer output function 53. When this signal is received, the virtual buffer output function 53 outputs a signal (T45) for requesting notification of the data size to the DSC 22 via the USB connection function 51 or the USBIF 12, and the DSC 22 responds with the response indicating the data size. The signal of (T46) is output to the virtual buffer output function 53 via the USBIF 12 and the USB connection function 51.

  The virtual buffer output function 53 determines whether or not the notified data size (in this example, the size of the image data to be printed) is greater than or equal to a preset threshold (or exceeds the threshold) (T47), If it is equal to or greater than the threshold (or exceeds the threshold), a print request reject (T48) signal that rejects the print request is output to the DSC 22 via the USB connection function 51 or USBIF 12, and the subsequent processing is performed. Do not do it.

  Here, the processing of the data size request (T45) and the processing of the data size response (T46) shown in FIG. 7 are, for example, the processing of the print request (T5) and the processing of print request permission (T6) shown in FIG. In this case, the virtual buffer output function 53 determines whether the notified data size is less than a preset threshold value (or less than or equal to a threshold value), and less than the threshold value (or , Below the threshold value), a print request permission (T6) signal is output to the DSC 22.

Referring to FIG. 8, an example of a processing sequence when image data is reduced is shown.
In this example, when there is a print request from the DSC 22, the virtual buffer output function 53 requests the DSC 22 to notify the data size, and acquires data size information. The virtual buffer output function 53 transmits a print request permission to the DSC 22 and performs data transfer processing. Further, the virtual buffer output function 53 determines whether or not the data size is equal to or larger than a preset threshold value (or exceeds the threshold value), and if the data size is equal to or larger than the threshold value (or exceeds the threshold value), the image is output. Data reduction processing is performed and the result is output to the virtual buffer 54. After the data writing to the virtual buffer 54 is completed, the virtual buffer output function 53 transmits a print completion notification to the DSC 22 via the pict bridge function 52.

  Specifically, in the wireless terminal device 21 of this example, the connection request (T51) signal output from the DSC 22 is received by the USB connection function 51 via the USBIF 12, and the USB connection function 51 is connected to the DSC 22 (T52). ) Signal is output. Thereafter, for example, when an operation to instruct printing is performed by the user in the DSC 22, a print request (T 53) signal is output from the DSC 22 and received by the PictBridge function 52 via the USBIF 12 and the USB connection function 51.

  Then, the PictBridge function 52 outputs a print request (T54) signal to the virtual buffer output function 53. When this signal is received, the virtual buffer output function 53 outputs a signal (T55) for requesting notification of the data size to the DSC 22 via the USB connection function 51 or the USBIF 12, and the DSC 22 responds with the response indicating the data size. The signal (T56) is output to the virtual buffer output function 53 via the USBIF 12 and the USB connection function 51.

  Then, the virtual buffer output function 53 outputs a print request permission (T57) signal to the DSC 22 via the USB connection function 51 and the USBIF 12 in response to receiving the data size notification. Thereby, transmission (transfer) processing (T58) of data to be printed is performed from the DSC 22 to the virtual buffer output function 53 via the USBIF 12 and the USB connection function 51.

  Thereafter, the virtual buffer output function 53 determines whether or not the notified data size (the size of image data to be printed in this example) is equal to or larger than a preset threshold (or exceeds the threshold) (T59). ) If it is equal to or greater than the threshold (or exceeds the threshold), the received data (image data to be printed in this example) is reduced (T60), and the resulting data is virtually The process of writing to the buffer 54 (T61) is executed, and the virtual buffer 54 outputs a data write completion (T62) notification to the virtual buffer output function 53. As a result, the virtual buffer output function 53 outputs a print completion notification (T63) signal to the DSC 22 via the USB connection function 51 and the USBIF 12.

On the other hand, the virtual buffer output function 53 has received the notified data size (in this example, the size of the image data to be printed) is less than a preset threshold value (or less than the threshold value). A process (T61) for writing the data (image data to be printed in this example) into the virtual buffer 54 as it is is executed. Then, the subsequent processing is executed.
Note that the processing of the data size request (T55) and the data size response (T56) in the example of FIG. 8 may be omitted. In addition, the image data subjected to the data transfer process (T58) in the example of FIG. 8 is temporarily stored in the virtual buffer 54 or other storage unit in the wireless terminal device 21 by the virtual buffer output function 53 as needed. Image data size determination (T59) may be performed, and then image data reduction (T60) and data writing (addition or overwriting) (T61) may be performed.

As described above, the wireless terminal device 21 of this example is equipped with the USB connection function 51 having a connection function with the digital still camera 22 compatible with the PictBridge and the PictBridge function 52 for the printer.
Note that the wireless terminal device 21 of this example has a configuration conforming to a standard such as Non-Patent Document 3 or Non-Patent Document 4.

Further, the wireless terminal device 21 of this example has a function of outputting image data to the virtual buffer 54 instead of print output.
In addition, the wireless terminal device 21 of this example has a file transfer function 55 that detects that data has been output to the virtual buffer 54 and activates the wireless communication function 58.
Further, the wireless terminal device 21 of this example has a function of automatically making a transmission by the file transfer function 55 by registering a destination telephone number and other information in advance.

Further, in the wireless terminal device 21 of this example, for example, by monitoring the abnormal end of wireless communication by the file transfer function 55, a function of automatically retrying (retransmitting) is displayed, and whether or not it is a normal end is displayed. This function has a function of manually retrying (retransmitting) a transfer that has failed in communication. This further improves user convenience.
In addition, in the wireless terminal device 21 of this example, as an example, when the image data size received from the digital still camera 22 is equal to or larger than the threshold (or exceeds the threshold), printing is performed on the digital still camera 22. It has a function to send a request reject.
Moreover, in the wireless terminal device 21 of this example, as another example, when the image data size received from the digital still camera 22 is equal to or larger than the threshold (or exceeds the threshold), the image data is expanded. The image data is reduced and output to the virtual buffer 54. This eliminates the need for the user to set and change the image size of the DSC 22 and the set image size at the time of imaging with the wireless terminal device 21, thereby further improving user convenience.

  As described above, in this example, regarding a technique for outputting an image from a printer by an operation from, for example, a digital still camera 22 that is an imaging device compatible with PictBridge, a communication device having a data communication function (in this example, a wireless terminal device 21). ) Receives image data from the digital still camera 22 in response to a print request from the connected digital still camera 22, writes it into the storage unit (in this example, the virtual buffer 54), and terminates the writing. A print completion notification is transmitted to the still camera 22, and the image data is transmitted to a preset destination or a specified destination.

  Therefore, in this example, image data can be transmitted from the communication device (in this example, the wireless terminal device 21) by an operation from the general-purpose digital still camera 22, for example, and the user (user) of the communication device can transmit the image data. Convenience can be improved. In the above-described prior art, data must be stored in a PC or the like, and then the wireless terminal device 21 and the PC must be connected and transmitted, which takes time and effort. According to the present invention, a user can transmit a captured image simply by connecting the wireless terminal device 21 and the DSC 22 and performing a print request operation of the DSC 22. However, it can be executed, and the time required for image transmission can be greatly reduced. In a disaster prevention radio system or the like, it is necessary to quickly transmit image data in order to collect and transmit disaster information at the time of a disaster. Therefore, the simplification of operations and the reduction of the time required for transmission are very effective.

  Note that in the wireless terminal device 21 (an example of a communication device) of this example, a storage unit that stores image data is configured by the function of the virtual buffer 54, and the digital still camera 22 is configured by the functions of the USB connection function 51 and the USBIF 12. Connection means for connection is configured, and connection communication means for communicating with the digital still camera 22 connected by the connection means by the PictBridge function 52 is configured, and the wireless communication function 58 (the wireless unit 2 or Communication means for performing communication via a line (in this example, the wireless line 41) different from the connection by the connection means is configured by the function of the antenna 3), and includes a telephone number holding function 57, an MMI function 56, and an input unit 8 The function is configured to set the communication partner by the communication means in advance and the setting means having the function to set by designation The image output from the digital still camera in response to the print request output from the digital still camera 22 connected by the connection means being received by the connection communication means by the virtual buffer output function 53 or the file transfer function 55 Data is received and written to the storage means and stored, and when the writing is completed, the connection communication means transmits a print completion notification to the digital still camera (the above is the virtual buffer output function 53), together with this. The control means is configured to transmit the image data stored in the storage means to the other party set by the setting means by the communication means (the above is the file transfer function 55).

Here, the configuration of the system and apparatus according to the present invention is not necessarily limited to the configuration described above, and various configurations may be used. For example, in the above-described embodiment, the case where the wireless terminal device 21 performs image data transmission processing based on a print request by the pict bridge function of the DSC 22 is taken as an example. However, the print request from the digital camera in the present invention is not limited to the PictBridge method, and can correspond to various types of print requests. In this case, the PictBridge function 52 corresponds to the method. Thus, the processing contents are not particularly changed. Furthermore, in the processing of the file transfer function 55 of the above-described embodiment (FIG. 6), a case where data transmission is started by polling is taken as an example. However, the present invention is not limited to this, and the file transfer function 55 may start image data transmission based on data writing completion (T9 in FIG. 5) or printing completion notification (T10 in FIG. 5). In this case, the virtual buffer output function 53 transmits to the file transfer function 55 a signal indicating the completion of data writing or printing completion notification (or the notification itself is possible), and the file transfer function 55 is based on the signal. Image data transmission may be started. The present invention can also be provided as, for example, a method or method for executing the processing according to the present invention, a program for realizing such a method or method, or a recording medium for recording the program. It is also possible to provide various systems and devices.
The application field of the present invention is not necessarily limited to the above-described fields, and the present invention can be applied to various fields.
In addition, as various processes performed in the system and apparatus according to the present invention, for example, the processor executes a control program stored in a ROM (Read Only Memory) in hardware resources including a processor and a memory. A controlled configuration may be used, and for example, each functional unit for executing the processing may be configured as an independent hardware circuit.
The present invention can also be understood as a computer-readable recording medium such as a floppy (registered trademark) disk or a CD (Compact Disc) -ROM storing the control program, and the program (itself). The processing according to the present invention can be performed by inputting the program from the recording medium to the computer and causing the processor to execute the program.
