That is, when the digital camera 1 is brought close to the external device 9 with the front side of the camera body 3 facing the keyboard surface of the external device 9, communication is established, while the camera is connected to the keyboard surface of the external device 9. Communication is not established even when the back side of the main body 3 is brought closer. For the user, the grip unit 8 of the camera body 3 may be held close to the external device 9 in the same manner as during shooting and playback, and the display unit 15 of the digital camera 1 can be seen and externally displayed. Communication can be performed while the display unit 92 of the device 9 is also visible. Thereby, at the time of communication, the success / failure of transmission / reception, the contents of transmitted / received data, etc. can be easily visually confirmed by displaying on the display units 15 and 92.

  Then, when communication is established with the external device 9, the digital camera 1 according to the first embodiment first transmits data to the external device 9. The data transmitted here is, for example, shooting data recorded in the digital camera 1, such as a still image or a moving image shot by the digital camera 1. Further, sound data recorded during moving image shooting may be transmitted together. In the first embodiment, one piece of shooting data to be displayed for the external device 9 is selected and transmitted to the external device 9.

  The near field communication unit 96 is for performing near field wireless communication with the digital camera 1, and transmits and receives radio signals to and from the near field communication unit 18 of the digital camera 1 by an antenna, and demodulates the received signal. In addition, a transmission / reception circuit for modulating the transmission signal is provided. From the proximity communication unit 96, a communication signal for notifying the presence is periodically transmitted. The communication signal is for turning on the power of the digital camera 1. In the external device 9 assuming a notebook personal computer or the like, an AC power adapter can be used, and the charging capacity of the rechargeable battery is large, which is advantageous in terms of power compared to the digital camera 1. For this reason, in the first embodiment, the digital camera 1 can be automatically turned on by periodically sending a communication signal from the external device 9.

  The control unit 97 is realized by a CPU or the like, and is directed to each unit constituting the external device 9 based on an operation signal input from the operation unit 91, a program or data recorded in the recording unit 95, data transfer, or the like. To control the operation of the external device 9 in an integrated manner. The control unit 97 includes a received data display control unit 971. This received data display control unit 971 is received when communication is established when communication with the digital camera 1 is established and photographing data is received and when a display permission signal is received from the digital camera 1. Processing for displaying the photographing data on the display unit 92 is performed. When the display permission signal is not received, the reception data display control unit 971 does not display the received photographing data.

  Next, a processing procedure performed by the digital camera 1 will be described. The digital camera 1 according to Embodiment 1 is automatically turned on by a communication signal transmitted from the external device 9 even when the power is cut off, and starts the photographing data transmission process. It has become. FIG. 13 is a flowchart showing the procedure of the transmission process.

  As shown in FIG. 13, when the proximity communication unit 18 of the digital camera 1 comes close to the communicable area of the proximity communication unit 96 of the external device 9, the communication signal that the proximity communication unit 96 sends out periodically is received. As a result, electromagnetic induction occurs in the antenna of the near field communication unit 18, and communication with the external device 9 is established (step b1). Specifically, at this time, the activation unit 19 of the proximity communication unit 18 activates the control unit 20 by electromagnetic induction generated in the antenna, and the power source of the digital camera 1 is turned on (step b3). When the power of the digital camera 1 is turned on in this way, the process proceeds to a data transmission / display permission notification process (step b5). FIG. 14 is a flowchart illustrating a processing procedure of data transmission / display permission notification processing according to the first embodiment.

  In the data transmission / display permission notification process, first, the display control unit 201 performs processing for selecting shooting data to be displayed on the external device 9 and displaying the selected shooting data on the display unit 15 (step c1). At this time, for example, the latest shooting data or the shooting data reproduced first may be automatically selected as a display target, or a user's selection operation may be accepted, and one shooting data is set as a display target. The selected shooting data is displayed on the display unit 15. And the transmission control part 203 performs the process which transmits the imaging | photography data selected and displayed at step c1 to the external apparatus 9 via the near field communication part 18 (step c3).

  Subsequently, the display permission notification control unit 205 starts a timer and starts measuring time (step c5). Then, the communication remains established (step c7: Yes), and the standby state is entered until the time measured by the timer passes a predetermined time (step c9: No). In a state where the communication is established (step c7: Yes), if the timer has passed the predetermined time (step c9: Yes), the display permission notification control unit 205 displays the shooting data transmitted in step c3. A permission signal is notified to the external device 9 (step c11). And the control part 20 transmits the recording request | requirement of the imaging | photography data transmitted at step c3 to the external apparatus 9 (step c13), and transfers to step c17 after that.

  If the communication is interrupted before the predetermined time has passed, that is, if the digital camera 1 is moved away from the external device 9 (step c7: No), the display permission notification control unit 205 sends the display permission notification control unit 205 to the external device 9. Is displayed (step c15), and then the process proceeds to step c17.

  That is, in step c17, the control unit 20 puts the proximity communication unit 18 in a stopped state. Then, the process returns to step b5 in FIG.

  Next, a procedure of basic processing of the digital camera 1 when the power is turned on will be described. FIG. 15 is a flowchart illustrating a procedure of basic processing performed by the digital camera 1. When the power is turned on, the digital camera 1 performs processing according to the mode selected by the user operation. That is, when the currently selected mode is the shooting mode (step d1: Yes), the control unit 20 activates the imaging unit 11 to capture an image (step d3), and uses the captured image as a live view image. Processing to display on the display unit 15 is performed (step d5). Then, while there is no shooting instruction (step d7: No), the process returns to step d3 to repeat the process, and the live view image is updated and displayed for each frame. When a release switch (not shown) is pressed and shooting is instructed (step d7: Yes), shooting processing is performed and the generated shot image data is recorded in the recording unit 16 (step d9).

  On the other hand, when the current mode is not the shooting mode (step d1: No) and is in the playback mode (step d11: Yes), the control unit 20 performs playback processing of the shot image recorded in the recording unit 16, The captured images are sequentially switched as reproduced images and displayed on the display unit 15 (step d13). At this time, first, a list of images captured in the past may be displayed in a thumbnail format. Then, the captured image selected from the list may be reproduced and displayed as a reproduced image.

  Subsequently, the control unit 20 activates the proximity communication unit 18 (step d15), and when communication is established between the digital camera 1 and the external device 9 (step d17: Yes), the data transmission / display permission notification process is performed. The process moves to step d29 after that (step d19). This data transmission / display permission notification processing is performed in the same manner as the processing procedure shown in FIG. In the data transmission / display permission notification processing here, for example, the shooting data being played back is selected as shooting data to be displayed on the external device 9 and transmitted to the external device 9.

  When the current mode is not the playback mode (step d11: No) and the communication mode is set (step d21: Yes), the control unit 20 activates the proximity communication unit 18 (step d23). When communication is established between the digital camera 1 and the external device 9 (step d25: Yes), the process proceeds to a data transmission / display permission notification process (step d27), and then the process proceeds to step d29. The data transmission / display permission notification process in step d27 is performed in the same manner as the processing procedure shown in FIG.

  In step d29, it is determined whether or not to end the basic process. For example, when the power switch is instructed by operating the button switch 7, the present process is finished (step d29: Yes). On the other hand, if not finished (step d29: No), the process returns to step d1.

  Next, a processing procedure performed by the external device 9 will be described. FIG. 16 is a flowchart showing a procedure of basic processing performed by the external device 9. Here, it is assumed that the external device 9 is turned on.

  As shown in FIG. 16, first, the control unit 97 starts periodic communication signal transmission processing by the proximity communication unit 96 (step e1). Then, when communication is established between the digital camera 1 and the external device 9 (step e3: Yes), the camera enters a standby state until it receives image data from the digital camera 1. When it is received (step e5: Yes), first, the received data display control unit 971 temporarily records the received shooting data in the recording unit 95 (step e7).

  Subsequently, when the received data display control unit 971 receives a display permission signal from the digital camera 1 (step e9: Yes), the received data display control unit 971 performs a display process of the received shooting data (step e11). In addition, the control unit 97 responds to the recording request from the digital camera 1 and performs recording processing of the received shooting data (step e13), and proceeds to step e35. On the other hand, if the reception data display control unit 971 does not receive the display permission signal (step e9: No) and the predetermined time has elapsed without receiving the display permission signal (step e15: Yes), the reception data display control unit 971 temporarily records it. The photographed data is deleted (step e17), and the process proceeds to step e35.

  On the other hand, when viewing of the television is instructed by a user operation (step e19: Yes), the control unit 97 performs a process for outputting a broadcast program of the channel selected by the user (step e21). If an instruction to end watching TV is given, the process proceeds to step e35. When an Internet connection instruction is input by a user operation (step e23: Yes), the control unit 97 performs a process for connecting to a site designated by the user via the network N (step e25). . If disconnection to the Internet is instructed, the process proceeds to step e35.

  When a content recording instruction is input by a user operation (step e27: Yes), a process of recording content data designated by the user in the recording unit 95 is performed (step e29). The content data recorded here includes, for example, content data disclosed / provided on a site on the Internet connected in step e25. When this content data is recorded, a content data download request is transmitted to the connected site, and the designated content data is acquired and recorded in the recording unit 95. The acquisition of content data is not limited to that provided on the Internet, and may be provided by an information recording medium such as a memory card or a CD-ROM. When the recording of the content data is finished, the process proceeds to step e35.

  When a content data reproduction instruction is input by a user operation (step e31: Yes), the content data designated by the user is read from the recording unit 95 and reproduced (step e33). The content data to be reproduced here is downloaded by connecting to the Internet or the like, and in addition to the content data recorded in the recording unit 95 in step e29, the digital data received in steps e5 (Yes) to step e13 and recorded in the recording unit 95 Shooting data (still image data, moving image data, sound data) from the camera 1 is included. If the end of reproduction of the content data is instructed, the process proceeds to step e35.

  In step e35, it is determined whether or not the basic process is to be ended. If the basic process is to be ended (step e35: Yes), this process is ended. On the other hand, if not finished (step e35: No), the process returns to step e3.

  As described above, according to the first embodiment, when communication is established with the external device 9 in the digital camera 1, shooting data to be displayed is transmitted to the external device 9, and then the external device 9. The display permission signal can be transmitted to the external device 9 when communication with the device is established for a predetermined time, and the photographing data to be displayed can be displayed on the external device 9. Therefore, it is possible to easily display the shooting data recorded in the digital camera 1 on the external device 9 or to cancel the display easily. According to this, even when an erroneous operation is performed, for example, when photographing data that the user does not want to display is erroneously selected as a display target, the display of the photographing data on the external device 9 can be easily canceled. Then, it is possible to easily redo the display of the shooting data on the external device 9 by selecting again the shooting data to be displayed on the external device 9 and bringing it closer to the external device 9 again.

  Even when the power of the digital camera 1 is shut off, it is only necessary to bring the digital camera 1 close to the external device 9, and data can be transmitted to and received from the external device 9 without turning on the power of the digital camera 1. Yes. Furthermore, the proximity communication unit 18 for performing proximity wireless communication with the external device 9 is activated only during communication, and is not driven while communication is not being performed. As a result, the power consumption of the digital camera 1 can be suppressed.

  Here, the proximity wireless communication between the proximity communication units 18 and 96 is a proximity wireless communication that is performed in a non-contact state and is capable of high-speed and large-capacity data transfer, and can achieve a transfer speed of, for example, 375 Mbps or more. A non-contact proximity wireless communication is assumed. Thereby, shooting data such as still image data, moving image data, and sound data recorded in the digital camera 1 can be instantaneously transmitted to the external device 9.

  In the first embodiment described above, the display permission signal is notified when the state where the communication is established continues for a predetermined time, but the following may be performed. That is, after the display permission signal is notified to the external device 9, the display continuation signal may be notified while communication is established. In this case, photographing data can be displayed on the external device 9 only while the digital camera 1 is approaching the external device 9, and the display can be lost by moving the digital camera 1 away from the external device 9.

  The recording request may be transmitted to the external device 9 as appropriate. For example, if it is only necessary to display the shooting data on the external device 9 and recording is not necessary, the recording request is transmitted by the digital camera 1 or the shooting data is recorded in the external device 9 that has received the recording request. There may be no configuration.

  The recording request may be transmitted to the external device 9 according to a user operation. The user operation may be performed on the digital camera 1 or may be performed on the external device 9. Alternatively, the control is performed for a remote controller that transmits various control signals to the external device, and the external device records the displayed shooting data in accordance with the remote control operation.

  Here, an example of a recording request transmission instruction to the digital camera 1 will be described. FIG. 17 is an explanatory diagram for explaining a recording request transmission instruction to the external device 9. For example, a displacement pattern of the camera body 3 is assigned in advance as a recording request transmission instruction. FIG. 17 illustrates a case where a displacement pattern for rotating the camera body 3 counterclockwise is assigned. That is, when it is desired to record the shooting data in the external device 9, the user first brings the camera body 3 close to the external device 9 to establish communication. Subsequently, as indicated by an arrow A7 in FIG. 17, the camera body 3 is rotated and moved counterclockwise on the keyboard surface of the external device 9. When the camera body 3 is rotated and moved in this way, a recording data recording request is transmitted from the digital camera 1 to the external device 9. At this time, a screen W 7 as shown in FIG. 17 is displayed on the display unit 15 of the digital camera 1, and a display permission signal is transmitted to the external device 9.

  FIG. 18 is a flowchart showing a processing procedure of data transmission / display permission notification processing performed by the digital camera 1 in this case. In FIG. 18, the same processing steps as those in FIG. 14 are denoted by the same reference numerals. That is, after step c11, the displacement detector 13 detects the displacement of the camera body 3 (step c111), and based on the result of the displacement detection, the controller 20 sends a recording request in which the camera body 3 is set in advance. It is determined whether or not it has been moved according to the pattern. When determining that the camera body 3 has been moved according to the recording request pattern (step c113: Yes), the control unit 20 transmits a recording request to the external device 9 (step c115).

  According to this, the recording operation by the user can be realized by detecting the movement of the camera body 3. In addition to this, for example, transmission of shooting data to the external device 9 and notification of a display permission signal or a display continuation signal may be performed in response to an operation input by the user. Set it. According to this, these processes can be easily and reliably performed according to the operation input by the user. Note that the displacement pattern of the camera body 3 assigned to the operation instruction includes, for example, a displacement that slides in a state in which the camera body 3 is brought close to the external device 9 in addition to the displacement that rotates the camera body 3 shown in FIG. The displacement etc. which incline the main body 3 can be set suitably.

(Embodiment 2)
Next, a second embodiment will be described. In the second embodiment, a television is exemplified as an external device instead of the notebook computer of the first embodiment. FIG. 19 is an explanatory diagram showing a state in which the digital camera 1a and the external device 9a of the second embodiment communicate with each other from the side surface side. As shown in FIG. 19, the near field communication unit 96a of the external device 9a is provided such that an antenna is disposed on the front surface on which the display unit 15 is disposed. When the proximity communication unit 96a and the proximity communication unit 18 of the digital camera 1a come close to each other within a communicable range, communication is established between the digital camera 1a and the external device 9a. Therefore, communication can be performed while the display unit 15 of the digital camera 1a is visible and the display unit 92b of the external device 9a is also visible.

  In the second embodiment, when the digital camera 1a is brought close to the external device 9a, a plurality of shooting data is transmitted to the external device 9a. As the shooting data to be transmitted, a part or all of the shooting data recorded in the digital camera 1a is automatically selected as shooting data to be displayed on the external device 9a. For example, if there is photographing data that has been transmitted to the external device 9a, untransmitted photographing data excluding this transmitted photographing data is selected, and if there is no transmitted photographing data, all photographing data is selected. And it transmits to the external device 9a in order from the newest shooting date. Alternatively, an operation for selecting shooting data is accepted, and shooting data selected by the user and data having a shooting date and time older than the shooting data are displayed, and are sent to the external device 9a in order from the latest shooting date and time. Also good.

  20 and 21 are diagrams for explaining the principle of photographing data display permission notification according to the communication status in the second embodiment. As shown in FIG. 20, when the digital camera 1a is brought close to the external device 9a, communication is established between them, and a plurality of pieces of shooting data are sequentially transmitted from the digital camera 1a to the external device 9a. In the external device 9a, the shooting data D1 transmitted from the digital camera 1a is sequentially displayed on the display unit 92a in the order of reception. FIG. 22 is a diagram illustrating a layout example of shooting data that is moved and displayed over time.

  For example, as shown in FIG. 22, the captured data D21 and D23 received from the lower right side sequentially appear on the screen of the display unit 92a (a). The shooting data D21, D23 and the newly appearing D25, D27 are gradually enlarged and moved so as to spread over the entire screen (b), and finally arranged and displayed in the screen ( c). Although FIG. 22 illustrates a case where four pieces of shooting data are displayed, the external device 9a appropriately sets a layout according to the number of received shooting data.

  On the other hand, as shown in FIG. 21, when the digital camera 1a is moved away from the external device 9a, the display of the photographing data D1 disappears on the display unit 92a of the external device 9a. For example, contrary to the communication establishment shown in FIG. 22, the respective captured data D21, D23, D25, D27 arranged in the screen are gradually reduced toward the lower right toward the screen (c). An effect display that moves is made (b) and disappears from the screen sequentially (a).

  FIG. 23 is a diagram for explaining the outline of communication performed between the digital camera 1a and the external device 9a in the second embodiment. As shown in FIG. 23, when the digital camera 1a receives a communication signal transmitted from the external device 9a (f1) and transmits a reception notification (step f3), communication is performed between the digital camera 1a and the external device 9a. Established. When the communication is established, the external device 9a notifies the digital camera 1a of the standby state (f5). In response to this, the digital camera 1a transmits the first image data to the external device 9a. The external device 9a receives the image data (f7), and notifies the digital camera 1a of the completion of reception of the image data (f9).

The digital camera 1a that has received the notification notifies the external device 9a of a display permission signal and transmits the second image data to the external device 9a when the predetermined time t _s1 has elapsed with communication established. . When the external device 9a receives the display permission signal and receives the second image data (f11), the external device 9a performs a process of displaying the first image data received at f7 on the display unit 92a, and starts display. To the digital camera 1a (f13). In response to this, in the digital camera 1a, when the predetermined time t _s1 elapses while communication is established, a display continuation signal is notified to the external device 9a, and the next photographing data is transmitted to the external device 9a. To do. When the external device 9a receives the display continuation signal and receives the next shooting data (f15), the external device 9a performs a process of displaying the second shooting data received in f11 on the display unit 92a, and starts the display. The digital camera 1a is notified (f17). In the digital camera 1a, when the predetermined time t _s1 elapses while communication is further established, a display continuation signal is notified to the external device 9a, and the next photographing data is transmitted to the external device 9a. Then, when the external device 9a receives the display continuation signal and receives the next shooting data (f19), the external device 9a performs a process of displaying the next shooting data received in f15 on the display unit 92a.

  This is repeated, and a plurality of pieces of shooting data are transmitted and received between the digital camera 1a and the external device 9a. Although not shown, the digital camera 1a appropriately notifies the external device 9a of a recording request, and the external device 9a that has received the recording request records the shooting data received by f7, f11, f15, f19, etc. Good.

  Next, processing procedures performed by the digital camera 1a and the external device 9a according to the second embodiment will be described. FIG. 24 is a flowchart illustrating a processing procedure of data transmission / display permission notification processing performed by the digital camera 1a according to the second embodiment. FIG. 25 is a flowchart illustrating a procedure of basic processing performed by the external device 9a according to the second embodiment. In FIG. 24 and FIG. 25, the same processing steps as those in FIG. 14 and FIG.

  In the data transmission / display permission notification process according to the second embodiment, the display permission notification control unit maintains communication after step c5 (step g5: Yes), and the timer count is set in advance. Until the time elapses (step g7: No), a standby state is entered. In a state where communication is established (step g5: Yes), if the timer has passed the predetermined time (step g7: Yes), the display permission notification control unit permits display of the photographing data transmitted in step c3. The signal is notified to the external device 9a (step g9), and the process of transmitting the next photographing data to the external device 9a is performed (step g11). When all the selected shooting data is transmitted to the external device 9a (step g13: Yes), the process proceeds to step g25.

  On the other hand, if there is still image data that has not been transmitted (step g13: No), if communication is still established (step g15: No), the timer counts up to a predetermined time. Until (step g17: No), it will be in a standby state. In a state where the communication is established (step g15: No), if the time count of the timer has passed a predetermined time (step g17: Yes), the display permission notification control unit notifies the external device 9a of a display continuation signal. At the same time (step g19), the process returns to step g11 to perform processing for transmitting the next display target shooting data to the external device 9a. In response to the display continuation signal notified in step g19, the external device 9a performs display processing on the display unit 92a of the photographing data transmitted last time in step g11.

  On the other hand, when the communication is interrupted before the predetermined time has passed in step g15 or step g17 (step g15: No, step g17: No), the display permission notification control unit stops the display on the external device 9a. A warning to the effect is displayed (step g21), and then the process proceeds to step g25.

  That is, in step g25, the control unit stops the proximity communication unit and ends the process.

  Then, in the external device 9a, as shown in FIG. 25, when communication is established between the digital camera 1a and the external device 9a in step e3 (step e3: Yes), one transmitted from the digital camera 1a is then transmitted. The system waits for reception of the first imaging data, and if it is received (step e5: Yes), the reception data display control unit temporarily records the first imaging data in the recording unit (step e7). Then, the reception data display control unit is in a standby state while not receiving the display permission signal (step e9: No).

  When the display permission signal is received (step e9: Yes), the reception data display control unit performs display processing of the first image data received in step e5 (step e11). The reception data display control unit receives the shooting data transmitted from the digital camera 1a following the display permission signal, and temporarily records the shooting data in the recording unit (step h13). Then, the reception data display control unit is in a standby state while not receiving the display continuation signal (step h15: No). When the display continuation signal is received (step h15: Yes), the reception data display control unit performs display processing of the photographing data received at step h13 (step h17).

  On the other hand, when the predetermined time has elapsed without receiving the display permission signal at step e9, or when the predetermined time has elapsed without receiving the display continuation signal at step h15 (step h19: Yes), the received data display control unit Deletes the temporarily recorded image data (step e17), and proceeds to step e35.

  As described above, according to the second embodiment, the digital camera 1a is moved closer to the external device 9a for a predetermined time, and the digital camera 1a is further moved closer to the external device 9a as it is, so that a plurality of selected pieces of shooting data are selected. Are sequentially displayed on the display unit 92a of the external device 9a, and the display on the display unit 92a of the external device 9a can be continued. On the other hand, the display on the display unit 92a of the external device 9a can be eliminated by moving the digital camera 1a away from the external device 9a. Therefore, it is possible to easily display a plurality of shooting data recorded in the digital camera 1a on the external device 9a or cancel the display.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the invention.

(Modification 1)
FIG. 26 is a block diagram illustrating an example of a main internal configuration of the digital camera 1b according to the first modification. FIG. 27 is an explanatory diagram showing a state in which the digital camera 1b and the external device 9 communicate with each other from the side surface side. In FIG. 26 and FIG. 27, the same components as those in the first embodiment are denoted by the same reference numerals. FIG. 27 shows a modification of the first embodiment, but the same applies to the second embodiment.

  As illustrated in FIG. 26, the digital camera 1 b according to the first modification is realized by, for example, a gravity sensor and includes a posture detection unit 23 b that detects the posture of the camera body 3. As shown in FIG. 27, the posture detection unit 23b is disposed at the bottom of the camera body 3, and outputs the direction of gravity with respect to a local coordinate axis (see FIG. 8) fixed to the digital camera 1b as posture information. . As described above, this local coordinate axis is irrelevant to the posture of the camera body 3, and the posture of the camera body 3 when the communication with the external device 9 is established is detected by the posture detection unit 23 b.

  FIG. 28 is a diagram showing a state in which the camera body 3 of the digital camera 1b is held in the same manner as during shooting and playback, and shows the correct posture (reference posture) of the camera body 3 during communication. On the other hand, FIG. 29 is a diagram showing an example of the posture of the camera body 3 different from the reference posture, and shows a state in which the digital camera 1b is held with the state shown in FIG. Yes. In the embodiment described above, the displacement of the camera body 3 is detected on the assumption that the posture of the camera body 3 when the communication with the external device 9 is established is the reference posture shown in FIG. . However, there is a problem in that it is impossible to determine whether the posture of the camera body 3 when the communication is actually established is the reference posture shown in FIG. 28 or a posture different from the reference posture shown in FIG.

  In the first modification, the posture of the camera body 3 when the control unit 20b in FIG. 26 establishes communication with the external device 9 based on the posture information output from the posture detection unit 23b is the reference posture. It is determined whether or not. Specifically, it is determined as the reference posture when the posture of the camera body 3 is directed downward.

  According to the first modification, the posture of the camera body 3 in the vertical and horizontal directions can be defined. Therefore, data can be transmitted and received only when the posture of the camera body 3 when the communication is established is the reference posture. Further, as described in the modification of the first embodiment, when the user instructs the recording of the shooting data by the movement of the camera body 3, the transmission of the shooting data, the display of the transmitted shooting data, etc. If it is applied to the case where the user instructs, the movement of the camera body 3 can be detected after determining whether or not the camera body 3 is in the reference posture. According to this, the instruction by the user operation can be reliably detected without error.

(Modification 2)
In the first modification described above, the displacement of the camera body 3 is detected by the displacement detector 13 such as an acceleration sensor or an angular velocity sensor. However, the displacement of the camera body 3 may be detected by image processing. . FIG. 30 is a block diagram showing an example of the main internal configuration of the digital camera 1c in this case. In FIG. 30, the same components as those in the above-described embodiment are denoted by the same reference numerals. The digital camera 1c of Modification 2 includes an image change detection unit 25c instead of the displacement detection unit 13 of FIG.

  The image change detection unit 25c is for detecting a motion between frames based on the image data output from the imaging unit 11, and is the same in each live view image captured by the imaging unit 11 for each frame. A motion vector representing the amount of change in the subject position is calculated. Then, the control unit 20c detects the displacement of the camera body 3 by determining the moving direction of the camera body 3 based on the motion vector calculated by the image change detection unit 25c. According to the second modification, even if the digital camera does not include an angular velocity sensor or an acceleration sensor, the movement of the camera body 3 according to the recording request pattern as shown in FIG. 17 without adding a new configuration, for example. Can be detected.

(Modification 3)
In the second embodiment described above, a case has been described in which the digital camera 1a sequentially transmits a plurality of shooting data, and the shooting data is sequentially laid out and displayed on the display unit 92a as shown in FIG. 22 on the external device 9a side. However, the present invention is not limited to this. That is, in the digital camera 1a, one image in which shooting data (shot images) as shown in FIGS. 22A to 22C is laid out may be sequentially generated and transmitted to the external device 9a.

  FIG. 31 is a diagram illustrating an outline of communication performed between the digital camera and the external device in the third modification. As shown in FIG. 31, when a digital camera receives a communication signal transmitted from an external device (j1) and transmits a reception notification (step j3), communication is established between the digital camera and the external device. When communication is established, the external device notifies the digital camera of the standby state (j5). In response to this, the digital camera generates a first layout image (for example, one layout image in which a photographed image is laid out as shown in FIG. 22A) and transmits it to an external device. The external device receives this layout image (j7) and notifies the digital camera of the completion of data reception (j9).

The digital camera that has received this notification notifies the external device of a display permission signal when the predetermined time t _s1 has passed with communication established, and also displays the second layout image (for example, FIG. 22B). As shown, one layout image in which the photographed image is laid out is generated and transmitted to the external device. When the external device receives the display permission signal and receives the second layout image (j11), the external device performs a process of displaying the first layout image received in j7 on the display unit, and starts the display digitally. The camera is notified (j13). In response to this, the digital camera notifies the external device of a display continuation signal when a predetermined time t _s1 elapses while further establishing communication, and also displays the next-order layout image (for example, FIG. 22C). As shown in FIG. 1, a single layout image in which the captured image is laid out is generated and transmitted to the external device. When the external device receives the display continuation signal and receives the next layout image (j15), the external device performs a process of displaying the second layout image received at j11 on the display unit, and starts the display. (J17). This is repeated, and the layout image is transmitted and received between the digital camera and the external device. If the external device does not receive the display continuation signal or layout image even after a predetermined time t _s2 (for example, about 10 seconds) due to the interruption of communication, the external device has received it at j7, j11, j15, etc. The layout images are sequentially displayed in order from the newly received one.

(Other variations)
Further, although the digital camera according to the above-described embodiment has been described with respect to the case where data is transmitted / received to / from an external device with which communication has been established, communication may be performed only with a specific external device. In this case, a partner to be transmitted and received in the digital camera and the external device is registered in advance. If the other party with whom communication has been established is registered, transmission / reception is performed, and if not registered, transmission / reception is not performed.

  In addition, when communication is established with a digital camera while watching TV on an external device, and shooting data transmitted from the digital camera is received, output of the broadcast program is interrupted and priority is given to the received shooting data. Then, the playback process may be performed. It may be possible to set whether to give priority to the output of a broadcast program or the reproduction of captured data from a digital camera according to a user operation. If priority is given to the output of the broadcast program, the received shooting data may not be reproduced even if the shooting data is received from the digital camera during the output of the broadcast program. In addition, it is not always necessary to give priority to either one. For example, the display screen is divided into a screen for the received shooting data and a screen for the broadcast program, and the video data of the broadcast program and the still image data from the digital camera 1 are divided. Alternatively, the moving image data may be displayed side by side on each screen.

  In the above-described embodiment, the case where the activation unit 19 is provided in the digital camera 1 has been described. However, the activation unit may be provided in an external device. The communication signal may be periodically transmitted from the digital camera, and the external device may be activated when the communication signal is received. In this case, the communication signal transmission process may be terminated when a predetermined time has elapsed since the communication signal transmission process was started. Similarly, when the communication is interrupted after the communication is established once, the transmission process of the communication signal may be terminated when a predetermined time has elapsed since the disconnection. According to this, power consumption of the digital camera can be reduced. When a communication signal is transmitted from the digital camera, control for housing the imaging lens is performed before the communication signal transmission process is started.

  In the above-described embodiment, the portable device of the present invention is applied to a digital camera. However, the present invention is not limited to a digital camera. For example, a mobile phone, a portable game machine, a notebook computer, a portable music player, etc. It can be applied to various portable devices capable of transmitting and receiving data to and from other devices. For example, the present invention can be applied to a case where a portable music player which is an example of a portable device transmits / receives music data to / from an external device. Further, in a portable music player, the present invention can be similarly applied to a case where data associated with the music data such as CD jacket image data is transmitted / received to / from an external device together with the music data.

  In the above-described embodiment, shooting data has been described as an example of content data. However, the present invention can be similarly applied to a case in which data in which image data is associated with music data is displayed on an external device. The present invention can also be applied to the case where sound data such as music data and audio data is output on the external device side. For example, depending on the communication status between a portable device such as a music player that records music data and the external device. A configuration may be adopted in which the reproduction of audio data in the external device is permitted.

  In addition, the present invention can be similarly applied to the case where data recorded in an external device is displayed and / or output as sound on the portable device side. That is, the present invention can also be applied when content data is acquired from an external device by bringing the mobile device close to the external device. Then, the content data display on the portable device can be lost by moving the portable device away from the external device.
