The data bus 280 transmits image data in response to a request from the communication control unit 260 or the display control unit 250.

Next, the external appearance of the playback apparatus of this embodiment will be described with reference to FIG.
In FIG. 3, reference numeral 110 denotes a playback apparatus according to this embodiment. Reference numeral 311 denotes an image display (display unit) provided in the playback apparatus 110 of the present embodiment. Reference numeral 112 denotes a cross key arranged on the right side of the image display 311 included in the reproduction apparatus 110 of the present embodiment, and inputs a display image reproduction control instruction by the user. Reference numeral 313 denotes an antenna for wireless communication provided in the playback apparatus 110 of the present embodiment.

  Next, the operation of the playback apparatus 110 in this embodiment will be described with reference to the schematic diagram shown in FIG. The playback device 110 according to the present embodiment communicates with an image processing device (external device) 100 such as a digital camera via a wireless communication antenna 313.

  First, a case where the playback device 110 is in the landscape orientation will be described with reference to FIG. When the playback device 110 is in the landscape orientation, the image of the communication partner is not displayed in the image display area 111, and the image 113 obtained by imaging the image data stored in the memory card 232 in the playback device 110 is displayed. Note that an operation of an image to be displayed (an operation such as image forwarding / returning) is instructed via the cross key 112 which is a form of the operation unit 242.

  FIG. 1B shows a case where the playback device 110 is rotated 90 degrees in the illustrated direction from the state shown in FIG. First, when the posture detection unit 200 detects that the playback device 110 is in the portrait orientation, the image display area 111 of the image display 311 is divided into two images, an upper image display area 121 and a lower image display area 122. Divide into areas.

  In the divided image display area, the image data stored in the memory card 232 in the reproduction apparatus 110 is displayed as an image in the image display area 122 below the posture of the reproduction apparatus 110. Then, the image data received from the external device 100 of the communication partner is imaged and displayed in the image display area 121 on the upper side with respect to the attitude of the playback device 110.

  Further, the posture detection unit 200 detects that the cross key 112 is below the image display 311 with respect to the posture of the playback device 110. In the present embodiment, in a situation where the image display area 111 is divided and displayed, the posture detection unit 200 identifies an image closer to the operation member from the two display images, and accepts a user's reproduction operation using the cross key 112. .

  Therefore, in the posture shown in FIG. 1B, the device that holds the image displayed in the lower image display area 122, that is, the playback device 110 itself is the playback control target device. For example, when the right button of the cross key 112 is pressed from the user, the image data to be displayed next is read from the memory card 232 of the playback device 110 and the display content of the lower image display area 122 is updated. .

  FIG. 1C shows a case where the playback device 110 is rotated 180 degrees from the state shown in FIG. Note that this posture change is performed continuously, and the display mode is not switched when the posture is turned sideways.

  In the present embodiment, when the orientation detection unit 200 detects that the playback device 110 is in the longitudinal orientation, the orientation detection unit 200 may determine which orientation is shown in FIG. 1B or 1C. The attitude information is notified to the display control unit 250. The display control unit 250 divides the image display area 111 and displays an image in the reproduction apparatus 110 in an image display area below the attitude of the reproduction apparatus 110. Then, the image data received from the external device 100 of the communication partner is imaged and displayed in the image display area on the upper side with respect to the posture of the playback device 110.

  That is, when the orientation of the vertical position is changed from the state shown in FIG. 1B as shown in FIG. 1C, an image based on the image data stored in the memory card 232 in the playback device 110 is displayed. The lower image display area 122 is switched to be used as an area for displaying an image based on the image data received from the external device 100 of the communication partner.

  Further, the posture detection unit 200 detects that the cross key 112 is above the image display 311 with respect to the posture of the playback device 110. As described above, in order to reproduce the image closer to the operation member in the display image, in the posture shown in FIG. 1C, the apparatus having the image displayed in the upper image display area 131, that is, The external device 100 of the communication partner is the playback control target device.

  In addition, the posture detection unit 200 notifies the operation unit 242 of the detected posture information of the playback device 110. Thereby, the operation unit 242 assigns the meaning of the function assigned to the cross key 112 in the state illustrated in FIG. 1B and the state illustrated in FIG. 1C based on the notified attitude information of the playback device 110. Is changed.

  For example, in the state shown in FIG. 1B, the right button of the cross key 112 provides a function of displaying the next image, but in the state of FIG. 1C, the cross key 112 corresponds to the left button. Therefore, it is changed so as to provide a function of displaying the previous image to the user. Thus, even if the operation members are the same in FIGS. 1B and 1C, the functions provided to the user are different.

  In addition, an identification display may be performed on the image in order to allow the user to discriminate the device that is subject to playback control. For example, in the case shown in FIG. 1B, the lower image display area 122 may be highlighted with a thick frame, or a special icon may be displayed. On the contrary, in the case shown in FIG. 1C, the upper image display area 131 may be highlighted with a thick frame or a special icon may be displayed.

Next, the processing procedure of the reproduction operation of this embodiment will be described with reference to the flowchart shown in FIG.
First, in step S1000, processing for comparing and reproducing an image owned by the reproduction apparatus 110 of the present embodiment and an image owned by the external apparatus 100 of the communication partner is started.

  Next, in step S1010, the communication control unit 260 checks whether it is connected to the external device 100 that holds the image data. If the result of this check is that there is no connection with the external device 100, processing proceeds to step S 1011. On the other hand, if it is determined in step S1010 that the external device 100 is connected, the process proceeds to step S1020.

  In the present embodiment, as described below, the display content is switched using a change in posture of the playback device 110 as a trigger, but there is no communication partner in step S1011. For this reason, in step S1011, the display control unit 250 displays only the image owned by the playback device 110 regardless of the posture information input from the posture detection unit 200 and waits for connection with the communication partner.

  On the other hand, in step S1020, posture detection section 200 checks whether or not the posture of playback device 110 is vertical. As a result of the check, if the posture detection unit 200 does not detect the vertical posture, the process proceeds to step S1021. On the other hand, if the posture detection unit 200 detects a vertical orientation as a result of the check in step S1020, the process proceeds to step S1025.

  Next, in step S <b> 1021, the display control unit 250 starts displaying an image owned by the playback device 110 using the entire area of the screen of the display 252. Note that even when an image owned by the playback apparatus 110 is being displayed in this step, the process returns to step S1020, and the posture detection unit 200 checks the vertical posture detection.

  On the other hand, in the case of the vertical orientation, in step S1025, the orientation detection unit 200 detects whether the playback device 110 is in the direction shown in FIG. 1B or the direction shown in FIG. To do. This is information necessary for determining the display contents at the time of screen division, which will be described later. In step S <b> 1030, the communication control unit 260 issues an image data acquisition request command owned by the external device 100 to the external device 100 of the communication partner, that is, a PULL command, and transmits the command to the external device 100.

  The external device 100 of the communication partner receives the image data acquisition request command issued by the playback device 110 issued in step S1030, and checks whether there is image data that can be browsed in the external device 100 of the communication partner. . Then, the presence / absence of image data is checked, and a command indicating the result is returned to the playback device 110.

  Next, in step S1040, the communication control unit 260 receives a command indicating the result, analyzes the command, and checks whether there is image data that can be browsed in the external device 100 of the communication partner. As a result of this check, if there is no viewable image data in the external device 100, the process proceeds to step S1041. On the other hand, if the result of the check in step S1040 is that there is viewable image data in the external device 100, the process proceeds to step S1045.

  In step S1041, the communication control unit 260 requests the external device 100 of the communication partner to notify the playback device 110 of an image data generation event when viewable image data is generated by imaging processing or the like. To do. Next, in step S <b> 1042, the communication control unit 260 cannot acquire an image from the external device 100 of the communication partner, so the display control unit 250 displays only the image owned by the playback device 110. In other words, the display control unit 250 displays only the images owned by the playback device 110 even though the posture detection unit 200 has input the posture information indicating the portrait orientation.

  Next, in step S1043, the communication control unit 260 issues the image data generation event requested by the external apparatus 100 of the communication partner to the playback apparatus 110 in step S1041, and whether or not this image data generation event has been received. Check. As a result of the check, if the communication control unit 260 receives an image data generation event, the process proceeds to step S1044. On the other hand, as a result of the check in step S1043, if the communication control unit 260 has not received an image data generation event, the process returns to step S1042, and the display control unit 250 continues displaying images owned by the playback device 110.

  Next, in step S <b> 1044, the communication control unit 260 issues an acquisition request for viewable image data owned by the external device 100 to the external device 100 of the communication partner, as in step S <b> 1030. Next, in step S <b> 1045, the communication control unit 260 receives the viewable image data transmitted by the external device 100 of the communication partner in response to the image data acquisition request in step S <b> 1044 or step S <b> 1030. At this time, the image data of the menu screen or setting screen corresponding to the external device 100 is also received simultaneously. You may make it receive both the image data of a menu screen, and the image data of a setting screen.

  Next, in step S1046, the display control unit 250 performs a process of comparing and reproducing the image based on the image data owned by the reproduction device 110 and the image owned by the external device 100 of the communication counterpart received in step S1045. This division comparison reproduction process will be described later. Even during the display of the image reproduced by the division comparison / reproduction processing in this step, the process returns to step S1020, and the posture detection unit 200 checks the vertical posture detection.

Hereinafter, the divided comparison reproduction process started in step S1046 will be described with reference to the flowchart shown in FIG.
First, in step S2000, the divided comparison reproduction process is started. Next, in step S2010, the display control unit 250 divides the image display area 111 of the playback device 110 into two. Then, according to the posture information detected by the posture detection unit 200 in step S1025, the vertical relationship information of the divided screen is acquired.

  Next, in step S2020, the display control unit 250 displays the image owned by the external device 100 of the communication partner received in step S1045 in the area determined as the upper screen area based on the hierarchical relationship information acquired in step S2010. To do. Next, in step S2030, the display control unit 250 displays the image owned by the playback device 110 in the area determined as the lower screen area based on the vertical relationship information acquired in step S2010.

  Next, in step S2040, the posture detection unit 200 determines whether the cross key 112 is above or below the image display 311 with respect to the posture of the playback device 110. If the result of this determination is that the playback device 110 is in the orientation shown in FIG. 1B and the cross key 112 is below the image display 311 with respect to the orientation of the playback device 110, the process advances to step S2041. On the other hand, if the result of determination in step S2040 is that the playback device 110 is in the posture shown in FIG. 1C and the cross key 112 is above the image display 311 with respect to the posture of the playback device 110, step The process proceeds to S2043.

  Next, in step S <b> 2041, the posture of the playback device 110 is the posture shown in FIG. 1B, and the cross key 112 exists below the image display display 311. In this case, since the image owned by the playback device 110 is displayed in the lower image display area 122 close to the cross key 112, the image owned by the playback device 110 is controlled in this step. Become. Therefore, in this step, the IO 240 checks whether or not a playback operation event such as image forwarding or image return has occurred by operating the cross key 112 by the user. If the result of this check is that a playback operation event has not occurred, the process waits until a playback operation event occurs. On the other hand, if the result of the check in step S2041 is that a playback operation event has occurred, the process proceeds to step S2042.

  Next, in step S2042, the display control unit 250 performs a playback process corresponding to the playback operation event generated in step S2041. For example, when the right button of the cross key 112 shown in FIG. 1B is pressed from the user, the image data recorded in the memory card 232 of the playback device 110 is displayed next. The image data is read out and an image based on the image data is displayed.

  On the other hand, in step S <b> 2043, the orientation of the playback device 110 is the orientation shown in FIG. 1C, and the cross key 112 is on the upper side with respect to the image display display 311. In this case, since the image owned by the external device 100 of the communication partner is displayed in the upper image display area 131 near the cross key 112, it is owned by the external device 100 of the communication partner in this step. The image becomes the control target. At this time, the display control unit 250 displays a menu screen corresponding to the external device 100 of the communication partner received at the same time in addition to the image in the upper image display area 131.

  Next, in step S <b> 2044, the IO 240 checks whether the user has processed a menu screen operation using the cross key 112 and has generated a playback operation event such as image forwarding or image return. If the result of this check is that a playback operation event has not occurred, the process waits until a playback operation event occurs. On the other hand, if the result of the check in step S2044 is that a playback operation event has occurred, the process proceeds to step S2045.

  Next, in step S2045, the communication control unit 260 notifies the communication partner external apparatus 100 of a reproduction processing command corresponding to the reproduction operation event generated in step S2044. For example, when the right button of the cross key 112 shown in FIG. 1C is pressed by the user, the communication control unit 260 notifies the image sending command to the external device 100 of the communication partner. The communication partner external device 100 receives this command, reads the next image data from the image owned by the external device 100, and transmits it to the playback device 110.

  Next, in step S2046, the communication control unit 260 receives image data from the external device 100 of the communication partner, and the display control unit 250 updates the image display in the upper image display area 131.

  As described above, in the present embodiment, when the attitude of the playback device 110 is changed, an image owned by the playback device 110 and an image owned by the external device 100 of the communication partner are displayed in comparison. Thereby, switching of the reproduction control object according to the position of the cross key 112 of the reproduction apparatus 110 can be easily realized.
