However, since the configuration other than the above-described components is not directly related to the present invention, in order to avoid complication of the drawings, the illustration thereof is omitted and the configuration similar to that of a conventional portable device or the like is omitted. The detailed description is omitted as it has.

  Among the communication methods for data communication by the portable device 1 of the present embodiment, as a communication method using infrared light, there are, for example, an IrDA (Infrared Data Association) standard, an IrSimple standard, and the like. is there.

  Here, for example, an outline of a communication method based on the IrSimple standard will be briefly described below.

  This communication method is configured by a multilayer layer structure. Among these, the first layer is called a transport layer / physical layer. The first layer is a physical connection configuration unit configured by hardware. The first layer is a layer for defining a communication method with a communication partner device and confirming a communication state and the like. In the mobile device 1 of the present embodiment, the communication state detection unit 7b of the communication unit 7 corresponds.

  The second layer is called the presentation layer. This second layer is a layer responsible for data division and reconstruction in response to a request from a third layer (application layer) described later.

  The third layer is called the application layer. The third layer is a layer for connecting an operation instruction by a user to application software (GUI) (Graphical User Interface) or the like.

  That is, when a connection request signal (Search & Connection signal) for searching for a communication partner device from a transmitting device and starting a connection is generated, a receiving device that is a communication partner device sends a response signal. Reply.

  When the transmission side device receives the response signal from the reception side device, it subsequently starts data communication (Data Exchange).

  When receiving all the transfer data from the transmitting device, for example, when receiving a data final signal (End Of File), the receiving device outputs a signal indicating that all data has been received.

  In response to this, the transmission side device outputs a signal (disconnect signal) to end the data communication. Upon receiving this, the transmitting side device outputs a signal indicating that the data communication end signal has been received.

  In response to this, the transmission side device ends the data communication operation.

  This series of communication sequences is performed in the communication unit 7 in the portable device 1 of the present embodiment.

  The process for determining whether communication is possible or not is performed in the first layer (transport layer / physical layer). As described above, in the mobile device 1 according to the present embodiment, this is performed in the communication state detection unit 7b of the communication unit 7.

  For example, the determination process that communication is possible is as follows. That is, a predetermined connection request signal is output from the first layer (transport layer / physical layer) of the transmission side device. When the receiving device receives this, the receiving device outputs a predetermined response signal. When the response signal is received within a predetermined time by the transmitting side device, it is determined that the transmitting side device is in a communicable state, and data communication processing is started.

  On the other hand, the process for determining that communication is impossible is as follows. That is, when a response signal from the receiving device cannot be received within a predetermined time in response to a predetermined connection request signal from the first layer (transport layer / physical layer) of the transmitting device, the transmitting device It is determined that the device is in a communication impossible state, and in the second layer (presentation layer), a disconnect signal is output and the data communication process is terminated.

  Next, the operation when data communication is performed in the mobile device 1 of the present embodiment will be described below with reference to the flowcharts of FIGS.

  In the following description, the communication sequence between the mobile devices 1 having the same specifications and the data communication sequence desired by the user is performed. A description will be given in association with the processing sequence (FIG. 3).

  First, it is assumed that both the mobile devices 1 of the transmission side device and the reception side device are in a power-on state and set in a communication mode.

  When the transmitting device is operating in the communication mode, in step S11 of FIG. 2, the signal processing / control unit 11 controls the display unit 5, the recording unit 4 and the like to display a data list on the display screen. Thus, a user operation is awaited. Here, when the user performs a data selection operation, a transmission data selection process is executed. This transmission data selection process is a process in which transmission data that the user desires to transmit is selected in advance prior to the execution of data communication.

  That is, the user operates a data selection operation member (not shown) to select arbitrary data from the list display. The instruction signal is output from the operation determination unit 2 to the signal processing / control unit 11. In response to this instruction signal, the data selection unit 11 a of the signal processing / control unit 11 selects data instructed to select from among a plurality of data recorded in the recording unit 4, and the data is recorded from the recording unit 4. A series of processes such as reading and temporarily storing in a temporary storage unit (not shown) or the like in the signal processing / control unit 11 and outputting it to the display unit 5 for display are performed. Note that, as data for transmission selected in this data selection process, for example, message data may be selected at the same time in addition to image data.

  Thus, when the transmission data selection process is completed, the process proceeds to the next step S12.

  In step S12, the signal processing / control unit 11 monitors the operation determination unit 2 to confirm whether or not a transmission operation signal has been generated. If it is confirmed that a transmission operation signal is generated, the process proceeds to the next step S13. When no transmission operation signal is generated, a series of processing sequences in the communication mode is terminated.

  In step S13, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to transmit a signal (Search & Connection signal) for searching for a partner device and requesting a connection. Then, the signal processing / control unit 11 starts measuring a predetermined time by the clock unit 6. Thereafter, the process proceeds to step S14.

  On the other hand, the reception side device performs reception mode selection processing in step S31 of FIG. This reception mode selection process is started when the user operates the operation mode switching operation member (not shown) to switch the operation mode of the receiving device to the reception mode (communication mode). When the reception mode selection operation is performed, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to switch the setting of each unit to a state of operating in the reception mode. When the receiving device is set to the reception mode, the process proceeds to the next step S32.

  In step S32, the signal processing / control unit 11 monitors the communication unit 7 via the communication control unit 11b, and searches for a partner device search / connection request signal (Search & Connection signal) transmitted by the communication unit 7 of the transmission side device. ) Is received. If reception of the partner device search / connection request signal is confirmed, the process proceeds to the next step S33. If reception of the counterpart device search / connection request signal is not confirmed, the series of processing sequences in the communication mode is terminated.

  In step S33, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, and transmits a response signal in response to the connection request. Thereafter, the process proceeds to step S34.

  Returning to FIG. 2, in step S <b> 14, the signal processing / control unit 11 monitors the communication unit 7 via the communication control unit 11 b from the communication unit 7 of the reception side device that is the counterpart device. It is confirmed whether or not the response signal is received within a predetermined time. For the predetermined time, refer to the clock unit 6 that has started measuring time in the process of step S13. If it is confirmed that the response signal has been received within the predetermined time, the process proceeds to the next step S15. If the response signal is not received within a predetermined time, the process proceeds to step S25.

  In step S <b> 25, the signal processing / control unit 11 controls the display unit 5 to display a warning such as “No partner device found”.

  Subsequently, in step S <b> 26, the signal processing / control unit 11 controls the display unit 5 to display “Do you want to continue?” Or the like, and enters an operation standby state in which the operation determination unit 2 is monitored. Here, the user determines whether or not to continue the operation process in the communication mode, and operates a predetermined operation member.

  In this case, when the user performs a predetermined operation indicating that the operation process in the communication mode should be continued, based on the instruction signal, the signal processing / control unit 11 returns to the process of step S13 and performs the subsequent processes. repeat. When the user performs a predetermined operation to stop the operation process in the communication mode, the signal processing / control unit 11 ends a series of processing sequences in the communication mode based on the instruction signal.

  When the response signal is received within the predetermined time in the process of step S14 of FIG. 2 and the process proceeds to the next step S15, in this step S15, the signal processing / control unit 11 sets the communication control unit 11b. The communication unit 7 is controlled via this to execute processing for starting transmission of the first data. Here, the first data is data for transmission that is selected by the user in the above-described step S11, is desired by the user to be transmitted, and is the main purpose of the transmission. That is, the first data is the main data (main data) transferred during data communication.

In this processing sequence, description will be made assuming that the first data is unprocessed image data acquired and recorded by, for example, a normal photographing operation.

  When all of the first data is transmitted, subsequently, in step S16, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, and terminates the transmission of the first data. Execute. Thereafter, the process proceeds to step S17.

  Subsequently, in step S <b> 17, the signal processing / control unit 11 confirms whether or not the data transmission processing is normally completed. Here, it is possible to determine whether or not the data transmission process has been normally completed by, for example, confirming whether or not the data transmission signal has been transmitted to the end of the transmission data file. If it is confirmed that the data transmission process is normally completed, the process proceeds to the next step S18. If it is determined that the data transmission process has not ended normally, the process proceeds to step S27.

  In step S <b> 27, the signal processing / control unit 11 controls the display unit 5 to display a warning message such as “It did not end normally”. Thereafter, the process proceeds to step S26 described above, and the same process is performed thereafter.

  In step S <b> 18, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11 b to execute processing for confirming the connection status of the counterpart device. This partner device connection status confirmation process is performed by the communication state determination unit 11c based on the detection result of the communication state detection unit 7b. Then, the signal processing / control unit 11 starts measuring a predetermined time by the clock unit 6. Thereafter, the process proceeds to step S19.

  On the other hand, when the transmission of the first data is started in the process of step S15 described above, in response to this, the signal processing / control unit 11 in step S34 of FIG. The communication unit 7 is controlled via the first and the process for starting the reception of the first data is executed. Then, after waiting for the first data transmission end process in the process of step S16 of FIG. 2 described above, the process proceeds to the next step S35.

  In step S <b> 35, the signal processing / control unit 11 confirms whether or not the data reception processing has been completed normally. Here, it is possible to determine whether or not the data reception process has been normally completed by, for example, confirming whether or not the data final signal attached to the end of the received data file has been received. If it is confirmed that the data reception process is normally completed, the process proceeds to the next step S36. If it is determined that the data reception process has not ended normally, the process proceeds to step S43.

  In step S <b> 43, the signal processing / control unit 11 controls the display unit 5 to display a warning message such as “It did not end normally”. Thereafter, the process proceeds to the next step S44.

  Subsequently, in step S44, the signal processing / control unit 11 controls the display unit 5 to display "Do you want to continue?" And enter an operation standby state in which the operation determination unit 2 is monitored. Here, the user determines whether or not to continue the operation process in the communication mode, and operates a predetermined operation member.

  In this case, when the user performs a predetermined operation indicating that the operation process in the communication mode should be continued, based on the instruction signal, the signal processing / control unit 11 returns to the process of step S33 and performs the subsequent processes. repeat. When the user performs a predetermined operation to stop the operation process in the communication mode, the signal processing / control unit 11 ends a series of processing sequences in the communication mode based on the instruction signal.

  When it is confirmed in the process of step S35 that the data reception process has been normally completed, and the process proceeds to the process of step S36, in this step S36, the signal processing / control unit 11 passes through the communication control unit 11b. The communication unit 7 is controlled to check whether or not a connection status confirmation signal (for example, a connection request signal) has been retransmitted from the counterpart device. If it is confirmed that the connection status confirmation signal is retransmitted, a response signal is returned and the process proceeds to the next step S37. If the retransmission of the connection status confirmation signal is not confirmed, the process proceeds to step S45.

  Returning to FIG. 2, in step S <b> 19, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11 b so that the signal strength from the counterpart device is sufficiently received for a predetermined time. It is confirmed whether or not a good communication state is secured.

  Here, the determination as to whether the signal strength from the counterpart device is sufficient is made based on the detection result by the communication state detection unit 7b.

  As described above, when the transmission side device transmits a connection status confirmation signal (connection request signal or the like) in the process of step S18 in FIG. 2, the reception side device responds to this in step S36 in FIG. If the response signal is returned in the process, the communication state detection unit 7b receives the response signal and outputs the detection result to the communication state determination unit 11c. In response to this, the communication state determination unit 11c determines the strength of the response signal and the like.

  For the predetermined time, refer to the clock unit 6 that started timing in the process of step S18 described above. The communication state determination unit 11c also determines whether or not the response signal continues for a predetermined time.

  Thus, when it is confirmed in the process of step S19 that the signal strength from the counterpart device is sufficiently received for a predetermined time, the process proceeds to the next step S20. If it is confirmed that the signal strength from the counterpart device is not sufficient or has not been received for a predetermined time, the process proceeds to step S23.

  In step S23, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to transmit a Disconnect signal. Thereafter, the process proceeds to step S24.

  Here, when the Disconnect signal is transmitted, in the receiving device, in step S45 of FIG. 3, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to transmit the transmitting device. It is confirmed whether or not a disconnect signal (see step 23 in FIG. 2) is received. If reception of the Disconnect signal is confirmed, the process proceeds to the next step S46. If reception of the Disconnect signal is not confirmed, the process proceeds to step S48.

  In step S46, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to transmit a response signal to the Disconnect signal. Thereafter, the process proceeds to step S47.

  In step S47, the signal processing / control unit 11 controls the display unit 5 to display that the reception of only the first data has been completed (for example, display such as “reception completed”). Thereafter, a series of processing sequences in the communication mode is ended.

  In addition, in the process of step S45 described above, when the reception of the Disconnect signal is not confirmed and the process proceeds to step S48, in this step S48, the signal processing / control unit 11 counts the predetermined time by the clock unit 6. Start and check whether a predetermined time has passed. Here, the process returns to the above-described step S36 until the predetermined time elapses, and the subsequent processes, that is, the process of retransmitting the connection status confirmation signal from the counterpart device and the process of confirming the reception of the Disconnect signal are repeated. And when predetermined time passes, it progresses to the process of following step S49.

  Subsequently, in step S49, the signal processing / control unit 11 controls the display unit 5 to display an error message indicating that reception has not ended normally. Thereafter, a series of processing sequences in the communication mode is ended.

  Returning to FIG. 2, when it is confirmed that the signal strength from the counterpart device is sufficiently received for a predetermined time in the process of step S19 described above, the process proceeds to the next step S20. The signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to execute processing for starting transmission of the second data. Here, the second data is data such as message data recorded in advance in the message data storage unit 4a of the recording unit 4, for example. That is, the second data is accompanying data attached to the main data at the time of data communication.

  The message data transmitted here is the transmission data selected by the user in step S11 described above.

  Separately, the message data transmitted as the second data is specified message data set in advance from a plurality of message data recorded in the message data storage unit 4a, and the data communication operation is performed. When performed, the prescribed message data may always be transmitted.

  When all the second data has been transmitted, subsequently, in step S21, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to end the transmission of the second data. Execute. Thereafter, the process proceeds to step S22.

  Subsequently, in step S <b> 22, the signal processing / control unit 11 checks whether or not the data transmission processing has ended normally. Here, it is possible to determine whether or not the data transmission process has been normally completed by, for example, confirming whether or not the data transmission signal has been transmitted to the end of the transmission data file. If it is confirmed that the data transmission process is normally completed, the process proceeds to the next step S23. If it is determined that the data transmission process has not ended normally, the process returns to step S19 and the subsequent processes are repeated.

  In step S23, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to transmit a Disconnect signal. Thereafter, the process proceeds to step S24.

  Subsequently, in step S24, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, so that the receiving-side apparatus performs the processing in step S46 described above with respect to the disconnect signal or a step described later. The response signal transmitted in the process of S38 is received. In response to this, the signal processing / control unit 11 controls the display unit 5 to display “transmission completion” indicating that the transmission is completed. Thereafter, a series of processing sequences in the communication mode is ended.

  On the other hand, in the receiving side apparatus, when the retransmission of the connection status confirmation signal is confirmed in the process of step S36 in FIG. The communication part 7 is controlled via the control part 11b, and the process which starts reception of 2nd data is performed. Then, after waiting for the second data transmission end process in the process of step S21 of FIG. 2 described above, the process proceeds to the next step S38.

  In step S38, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, and determines whether or not a Disconnect signal (see the process of step 23 in FIG. 2) is received from the transmission side device. Confirm. Here, when the reception of the Disconnect signal is confirmed, the process proceeds to the next step S39. If reception of the Disconnect signal is not confirmed, the process proceeds to step S41.

  In step S39, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b and transmits a response signal to the Disconnect signal. Thereafter, the process proceeds to step S40.

  In step S40, the signal processing / control unit 11 controls the display unit 5 to display that the reception of the second data is also completed (for example, a display such as “reception completed”). Thereafter, a series of processing sequences in the communication mode is ended.

  Further, in the process of step S37 described above, when the reception of the Disconnect signal is not confirmed and the process proceeds to step S41, the signal processing / control unit 11 counts a predetermined time by the clock unit 6 in step S41. Start and check whether a predetermined time has passed. Here, the process of confirming the reception of the Disconnect signal in the process of step S38 is repeated until a predetermined time has elapsed. And when predetermined time passes, it progresses to the process of following step S42.

  Subsequently, in step S42, the signal processing / control unit 11 controls the display unit 5 to display an error message indicating that reception has not ended normally. Thereafter, a series of processing sequences in the communication mode is ended.

  When an error display is performed in the above-described steps S42 and S49, the error display can be reset by operating a predetermined operation member. In this case, for example, the error state in the communication mode is reset by switching from the communication mode to another operation mode by operating the operation mode switching operation member. Further, the power-off operation is performed using the power operation member, and various settings in the portable device 1 are once reset, and then the power-on operation is performed, whereby the error state in the communication mode is reset.

  As described above, according to the first embodiment, when data communication is performed between mobile devices using a communication method such as proximity wireless communication, for example, after transmission of first data (main data) such as image data is completed. However, if a good communication state with the communication partner device is continuously secured for a predetermined time, the second data (accompanying data) such as message data can be automatically transmitted continuously. .

  Whether or not to maintain the proximity state between devices, simply by performing an operation whether or not to maintain a good communication state without special operation by the user during data communication. Whether to transmit only the first data such as image data, or to transmit the second data such as message data in addition to the first data such as the image data, is easily used on the spot. be able to.

  In addition to simply sending main data, it is possible to arbitrarily send accompanying data such as message data created by the user, so it can be used as a function to communicate with the user of the other device Is also possible.

  As a portable device in the present embodiment, a description will be given by taking as an example a photographing apparatus (hereinafter simply referred to as a camera) such as a digital camera mainly composed of photographing functions.

  The basic configuration of the mobile device of this embodiment is exactly the same as that of the first embodiment described above. Therefore, the description of the configuration of the mobile device itself according to the present embodiment is omitted, and the first embodiment described above is referred to.

  The operation when data communication is performed between portable devices of the present embodiment is as shown in the camera control processing sequence of FIG.

  FIG. 4 also shows a processing sequence in the communication mode between the mobile device on the transmission side and the mobile device on the reception side. That is, when the operation mode of the camera that is the portable device of the present embodiment is set to the shooting operation mode, the normal shooting operation can be performed, and the reception standby state of the data communication request signal from another portable device is set. ing. Accordingly, when a connection request signal for data communication is received from another portable device when no release signal for starting shooting is generated at this time, it functions as a receiving-side portable device. (See steps S102 to S118 in FIG. 4). On the other hand, when the operation mode of the mobile device (camera) of the present embodiment is set to the playback mode, the normal playback operation can be performed, and communication with other mobile devices is performed to perform data transfer and the transmission side. (See steps S121 to S134 in FIG. 4).

  Note that the portable device (camera) of the present embodiment has a message input mode in which message data can be arbitrarily created by performing a predetermined operation as an operation mode other than these (see steps S141 and S142 in FIG. 4). ).

  First, a processing sequence when the mobile device (camera) of the present embodiment is set to the shooting operation mode will be described.

  In step S101 of the camera control processing sequence in FIG. 4, the signal processing / control unit 11 monitors the operation determination unit 2 to determine whether a power-on signal is generated from a power operation member (not shown) of the camera. Confirm. Here, when it is confirmed that the power operation member is operated by the user and the power on signal is generated, the process proceeds to the next step S102. If the power-on signal is not confirmed, the process of step S101 is repeated.

  In step S102, the signal processing / control unit 11 monitors the operation determination unit 2 and the like, and based on a signal from a camera operation mode switching operation member (not shown) or the like, the current operation mode status is set. Confirm. If it is confirmed that the shooting operation mode (simply referred to as the shooting mode in FIG. 4) is set, the process proceeds to the next step S103. On the other hand, when it is confirmed that an operation mode other than the shooting mode is set, the process proceeds to step S121 (the subsequent processing sequence will be described later).

  In step S103, the signal processing / control unit 11 controls the imaging unit 3, the display unit 5 and the like to execute live view display operation processing. The live view display operation process is an operation process in which images based on image signals continuously acquired by the imaging unit 3 are sequentially displayed on the display screen of the display unit 5 to display a real-time image. While continuing the real-time image display, the process proceeds to the next step S104.

Subsequently, in step S104, the signal processing / control unit 11 monitors the operation determination unit 2 and the like to confirm whether or not a shooting instruction signal of the camera is generated. Here, when it is confirmed that a shutter release button or the like as an operation member for performing a photographing operation is operated by the user and a photographing instruction signal (release signal) is generated, the process of the next step S105 is performed. In step S105, predetermined processing such as normal photographing operation and recording operation is executed. After completion of these photographing / recording operation processes, the process returns to the above-described step S101, and the subsequent processes are repeated.

In addition, when performing normal imaging | photography and recording using the camera which is a portable apparatus of this embodiment, it will be in a state as shown in FIG. That is, FIG. 5 shows a situation where the user is holding the camera 1 and shooting a person as a subject. The image shown by the image data acquired in this way is, for example, as shown in FIG.

  On the other hand, if it is confirmed in the process of step S104 described above that no shooting instruction signal (release signal) has been generated, the process proceeds to step S111.

  In step S111, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, the communication state determination unit 11c, etc., and signals such as connection requests from other portable devices, that is, transmission side devices. Confirm whether or not is received. Here, when reception of a connection request signal or the like from another device is confirmed, the process proceeds to the next step S112. If signal reception from another device is not confirmed, the process returns to step S101 described above and the subsequent processes are repeated.

  In addition, the state at the time of performing close proximity wireless communication etc. between the camera which is a portable apparatus of this embodiment and the camera which is a portable apparatus of the same form is a state as shown in FIG. That is, FIG. 6 shows that the transmission / reception unit 8 of the camera 1A, which is a transmission-side portable device, and the transmission / reception unit 8 of the camera 1B, which is a reception-side portable device, are brought close to each other. In this case, the transmission / reception units 8 of both cameras 1A and 1B are arranged to face each other, and the distance between them is in the close state. At this time, the cameras 1A and 1B may be in a non-contact state if the distance between the transmission / reception units 8 is within a predetermined distance. For example, the exterior parts of both the cameras 1A and 1B are in contact. Also good. Note that the predetermined distance interval is preferably about 3 cm or less in, for example, one standard of close proximity wireless communication.

  In step S112, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, and transmits a response signal to another portable device. Thereafter, the data reception state is maintained.

  Subsequently, in step S113, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b, and confirms whether or not the final signal from the mobile device on the transmission side has been received. If it is confirmed that the final signal has been received, the process proceeds to the next step S116. If the reception of the final signal is not confirmed, the process proceeds to step S114.

  Note that the final signal is a signal that is output when the transmission-side portable device completes transmission of all data to be transmitted during the data communication operation. By receiving this final signal, the receiving-side portable device is assumed to have completed a series of data communication operation processing.

  In step S <b> 114, the signal processing / control unit 11 starts measuring a predetermined time by the clock unit 6 and confirms whether or not the predetermined time has elapsed. If it is confirmed that the predetermined time has elapsed, the process proceeds to the next step S115.

  In step S115, the signal processing / control unit 11 controls the display unit 5 and the like to display a predetermined “warning” on the display screen. Thereafter, the processing returns to step S101, and the subsequent processing is repeated.

  If the predetermined time has not elapsed in the process in step S114, the process returns to the process in step S101, and the same process is repeated thereafter. That is, the same processing is repeated until the final signal is received.

  As the above-mentioned “warning” display, in addition to a visual warning display using the display screen of the display unit 5, a warning sound by a voice or the like using a voice output device such as a speaker included in the display unit 5 is used. It is good also as a warning display.

  On the other hand, if it is confirmed in step S113 that reception of the final signal is confirmed, the process proceeds to step S116. In step S116, the signal processing / control unit 11 starts the data communication after starting data communication. Check whether there was any interruption before receiving. Here, the case where there is an interruption during the data communication operation is assumed, for example, when a plurality of data is received.

  As will be described later, in the portable device of this embodiment, when the mobile device on the transmission side performs data communication operation, when the user desires to attach message data to the image data for transmission, First, after transmitting raw image data (selected image data for transmission) as it was shot, create composite image data by combining message data with the image data while maintaining the communication state. The composite image data is transmitted continuously. Therefore, in this case, the mobile device on the receiving side receives a plurality of image data of the raw image data and the composite image data received earlier.

  Therefore, in the process of step S116 described above, whether there is a plurality of received image data is confirmed based on whether or not there is a midway interruption during the reception operation. Here, if there is no interruption in the middle, it is determined that the received data is single, and the process proceeds to step S117.

  In step S117, the signal processing / control unit 11 controls the recording unit 4 and the display unit 5 to record the received data in the recording unit 4 and the display unit 5 for images based on the received data. Display operation is performed. Thereafter, the processing returns to the above-described step S101, and the subsequent processing is repeated.

  Further, in the process of step S116 described above, if there is an interruption in the middle, it is determined that there are a plurality of received data, and the process proceeds to step S118.

  In step S118, the signal processing / control unit 11 controls the recording unit 4, the display unit 5, and the like, and the received data after being interrupted during data communication among a plurality of received data, that is, transmitted later. The recording operation of the synthesized image data in the recording unit 4 and the display operation of the display unit 5 such as an image based on the lost image data are performed. Thereafter, the processing returns to the above-described step S101, and the subsequent processing is repeated.

  Next, a processing sequence when the portable device (camera) of the present embodiment is set to the playback mode will be described. A processing sequence in the message input mode will also be described.

  When it is confirmed in step S102 that the operation mode other than the shooting mode is set and the process proceeds to step S121, in step S121, the signal processing / control unit 11 The operation determination unit 2 and the like are monitored, and the status of the currently set operation mode is confirmed again based on a signal from an operation mode switching operation member (not shown) of the camera. If it is confirmed that the playback operation mode is set (represented simply as the playback mode in FIG. 4), the process proceeds to the next step S122. On the other hand, if it is confirmed that an operation mode other than the playback mode is set, the process proceeds to step S141.

  In step S141, the signal processing / control unit 11 monitors the operation determination unit 2 and the like, and based on a signal from a camera operation mode switching operation member (not shown) or the like, the current operation mode status is set. Confirm. If it is confirmed that the message input mode is set, the process proceeds to the next step S142. On the other hand, if it is confirmed that the operation mode is set to a mode other than the message input mode, the process returns to step S121, and the subsequent processes are repeated.

  In step S142, the signal processing / control unit 11 monitors the operation determination unit 2 and the like, and executes a message input operation process based on a message input operation by the user. Thereafter, when the message input operation is completed and the message input operation process is completed, the process returns to the above-described step S, and the subsequent processes are repeated.

  On the other hand, when it is confirmed that the playback mode is set in the process of step S121 described above, and the process proceeds to the process of step S122, in this step S122, the signal processing / control unit 11 performs the operation determination unit 2 and the like. And processing such as a reproduction operation and a selection operation is executed in accordance with an instruction signal generated by an operation by each operation member. Thereby, desired image data to be transmitted is set.

  Subsequently, in step S123, the signal processing / control unit 11 monitors the operation determination unit 2 and confirms whether or not an instruction signal for starting communication is generated. If the “communication” instruction signal is confirmed, the process proceeds to the next step S124. On the other hand, when the “communication” instruction signal is not confirmed, the process returns to the process of step S121 and the subsequent processes are repeated.

  In step S124, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to execute an image data transmission operation process. Thereafter, the process proceeds to step S125.

  In step S125, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to check whether or not the image data transmission operation process has been completed. If it is confirmed that the image data has been transmitted, the process proceeds to the next step S131. If it is confirmed that the image data has not been transmitted, the process proceeds to step S126.

  In step S126, the signal processing / control unit 11 starts measuring the predetermined time by the clock unit 6 and checks whether or not the predetermined time has elapsed. If it is confirmed that the predetermined time has elapsed, the process proceeds to the next step S127.

  That is, the case of proceeding to the process of step S127 means a state in which a predetermined time has passed without the transmission of image data being completed.

  Therefore, in step S127, the signal processing / control unit 11 controls the display unit 5 and the like to perform a predetermined “error display” on the display screen. Thereafter, the processing returns to step S123, and the subsequent processing is repeated. This “error display” means that data communication of image data has failed. Therefore, in this case, the process returns to the above-described step S123, and the image data transmission process is repeated.

  On the other hand, when it is confirmed in the process of step S125 that the image data has been transmitted and the process proceeds to the process of step S131, in step S131, the signal processing / control unit 11 passes through the communication control unit 11b. The communication unit 7 is controlled to check the communication state. This communication state confirmation process is performed by the communication state determination unit 11c in response to the detection result of the communication state detection unit 7b. Here, it is confirmed whether or not the communication state is “good for a predetermined time”, that is, whether or not the operation as shown in FIG. 6 is maintained by the user. Here, when it is confirmed that the communication state is “good for a predetermined time”, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b and maintains the communication state. Then, the process proceeds to the next step S135. If it is confirmed that the communication state is not “good for a predetermined time”, it is determined that the communication operation by the user has been released, and the process proceeds to step S132.

  In step S135, the signal processing / control unit 11 performs a process of combining the selected message data with the image data selected in advance in the process of step S122 described above to generate composite image data. Thereafter, the process proceeds to the next step S136.

  The message data used when generating the composite image data includes, for example, prescribed message data among a plurality of message data created in advance in the process of step S142 and recorded in the recording unit 4, or The message data selected together with the image data in the process of step S122 described above.

  Moreover, as an example of the composite image data generated here, for example, the one shown in FIG. In FIG. 8, a state in which message data composed of predetermined characters or the like is displayed superimposed on an image (image shown in FIG. 7) displayed based on image data acquired by photographing. Is shown.

  Subsequently, in step S136, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to execute a transmission operation process of the composite image data. Thereafter, the process proceeds to step S132.

  In step S132, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to confirm the communication state. This communication state confirmation process is performed by the communication state determination unit 11c in response to the detection result of the communication state detection unit 7b. Here, it is confirmed whether or not the communication state is a communicable state. Here, if it is confirmed that the communication state is the “communication enabled” state, the process proceeds to the next step S133.

  In step S133, the signal processing / control unit 11 controls the communication unit 7 via the communication control unit 11b to execute a final signal transmission process. Thereafter, the processing returns to the above-described step S123, and the subsequent processing is repeated.

  On the other hand, when it is confirmed in the process of step S132 described above that the communication state is the “communication impossible” state, the process proceeds to step S134.

  In step S134, the signal processing / control unit 11 controls the display unit 5 and the like to perform a predetermined “error display” on the display screen. Thereafter, the processing returns to step S123, and the subsequent processing is repeated.

  As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained.

  Further, according to the present embodiment, when data communication by a communication method such as close proximity wireless communication between mobile devices is started, first, only the selected image data is transferred, and the user is accompanied by message data. If the user wants to transmit the image data, the user simply maintains the state of FIG. 6 for a predetermined time, and the composite image data in which the message data is combined with the image data is automatically generated. At the same time, the composite image data is also transmitted.

  Therefore, when performing an operation of bringing portable devices (cameras) close to each other in order to perform close proximity wireless communication or the like, the user only performs an operation to increase or decrease the time for maintaining the proximity state, and transmits only image data. It is possible to easily determine whether to transmit the composite image data accompanied by the message.

  In the present embodiment, the processing step (S135) for generating the composite image data by combining the image data and the message data is performed during the data communication operation, but the present invention is not limited to this example.

  For example, the composite image data generation processing step may be performed immediately after selection processing of image data and message data, and the generated composite image data may be temporarily recorded.

  The present invention is not limited to the above-described embodiments, and it is needless to say that various modifications and applications can be implemented without departing from the spirit of the invention. Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if several constituent requirements are deleted from all the constituent requirements shown in the above-described embodiment, if the problem to be solved by the invention can be solved and the effect of the invention can be obtained, this constituent requirement is deleted. The configured structure can be extracted as an invention.
