[Configuration of image display device 1]
FIG. 3 is a diagram showing the configuration of the image display device 1. The image display device 1 includes a communication unit 11, a display unit 12, an operation unit 13, a storage unit 14, and a control unit 15. The control unit 15 includes a data acquisition unit 151, an operation reception unit 152, and a display control unit 153.

The communication unit 11 is a communication interface for receiving moving image data from the image distribution device 2 via the network N. The communication unit 11 inputs the received moving image data to the data acquisition unit 151.

The display unit 12 displays the moving image data input from the display control unit 153. The display unit 12 is, for example, a display.

The operation unit 13 is a device for receiving an operation of a user, and is, for example, a touch panel provided on the display unit 12 in an overlapping manner. The operation unit 13 notifies the operation reception unit 152 of the coordinate information indicating the position operated by the user.

The storage unit 14 is a storage medium including a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 14 stores a program executed by the control unit 15. The storage unit 14 may temporarily store the moving image data received by the communication unit 11.

The control unit 15 has, for example, a CPU (Central Processing Unit), and functions as a data acquisition unit 151, an operation reception unit 152, and a display control unit 153 by executing a program stored in the storage unit 14.

The data acquisition unit 151 is associated with the first moving image data including the first subject C1 and the time information common to the first moving image data via the communication unit 11, and the second moving image including the second subject C2. The image data and the image data are acquired from the image distribution device 2. The common time information is information indicating the time corresponding to the elapsed time from the start time of the whole moving image data Z including the subject C1 and the subject C2. The data acquisition unit 151 may further acquire the entire moving image data Z including the first moving image data and the second moving image data. The data acquisition unit 151 inputs the acquired first moving image data and the second moving image data to the display control unit 153. The data acquisition unit 151 may store the acquired first moving image data and the second moving image data in the storage unit 14.

In the present embodiment, the first moving image data is the main moving image data that is supposed to be mainly displayed, and the second moving image data is a sub-moving image that can be displayed in a part of the time zone. It is image data. For example, the user can always see the first moving image data, and can switch the first moving image data to the second moving image data only in a part of the time zone.

The operation reception unit 152 receives a switching operation for switching the moving image data to be displayed on the display unit 12 via the operation unit 13. The operation reception unit 152 receives, for example, a switching operation of swiping on the moving image data displayed on the display unit 12. As described above, the switching operation is, for example, a swipe operation described with reference to FIG. 1, but the method of the switching operation is arbitrary, such as an operation of touching an image for operation displayed on the display unit 12. It may be another method.

For example, the operation reception unit 152 may display an image of a left-pointing arrow or an image of a right-pointing arrow indicating the direction in which the swipe operation is performed on the screen of the display unit 12. The operation reception unit 152 may specify the content of the switching operation according to the direction of the touched arrow while displaying the image of such an arrow. As will be described later, when the time zone in which the second moving image data can be switched is limited, the operation reception unit 152 can perform the Skype operation or the touch operation only in the time zone in which the second moving image data can be switched. Information may be displayed to prompt the user, or only the image of the arrow pointing in the direction in which the time zone can be switched may be displayed.

Further, the operation receiving unit 152 may accept an operation for switching a chapter (for example, a scene) to be displayed in the moving image data. The direction of this switching operation is different from the operation for switching the moving image data, for example, the vertical direction. When the operation reception unit 152 switches to the previous chapter when a downward swipe operation is performed or the image of the downward arrow is touched, the operation reception unit 152 switches to the previous chapter, the upward swipe operation is performed, or the image of the upward arrow is touched. If so, switch to a later chapter. The operation reception unit 152 notifies the display control unit 153 of the content of the switching operation.

The display control unit 153 creates screen data to be displayed on the display unit 12, inputs the screen data to the display unit 12, and causes the display unit 12 to display various moving image data. As shown in FIGS. 1 (b) and 1 (c), the display control unit 153 causes the display unit 12 to display at least one of the first moving image data and the second moving image data. The display control unit 153 may display the entire moving image data Z including the first subject C1 and the second subject C2 on the display unit 12.

The display control unit 153 displays the moving image data to be displayed on the display unit 12 when the operation receiving unit 152 receives the switching operation while the first moving image data is displayed on the display unit 12. The data is switched to the second moving image data corresponding to the same time as the time of the first moving image data. The second moving image data corresponding to the same time as the time of the first moving image data may be the second moving image data included in the same overall moving image data Z as the first moving image data.

Here, as an example, the first moving image data and the second moving image data are generated by taking pictures in a state where the first subject C1 and the second subject C2 are arranged in a predetermined positional relationship. In the case of the example shown in FIG. 1, the subject C1 is arranged on the right side and the subject C2 is arranged on the left side in the whole moving image data Z. In this case, the display control unit 153 may switch the moving image data to be displayed on the display unit 12 on condition that the swipe is performed in a predetermined direction corresponding to the above-mentioned predetermined positional relationship.

The display control unit 153 switches to moving image data including a subject arranged in the direction of the swipe operation, for example. Specifically, in the case of the example shown in FIG. 1, the display control unit 153 is opposite to the side of the first subject C1 to the second subject C2 while displaying the first moving image data on the display unit 12. The moving image data to be displayed on the display unit 12 is switched from the first moving image data to the second moving image data on condition that the swipe is made in the direction. The display control unit 153 may switch to moving image data including a subject arranged on the side in the direction of the swipe operation.

In the case of the example shown in FIG. 1, the display control unit 153 is on the side where the subject C2 is arranged while the first moving image data is displayed on the display unit 12 as shown in FIG. 1 (b). When a swipe operation toward the right side is performed, the data is switched to the second moving image data, and when a swipe operation toward the left side is performed, the data is not switched to the second moving image data. Similarly, the display control unit 153 swipes toward the left side on which the subject C1 is arranged while the second moving image data is displayed on the display unit 12 as shown in FIG. 1 (c). When the operation is performed, the data is switched to the first moving image data, and when the swipe operation to the right is performed, the data is not switched to the first moving image data. By operating the display control unit 153 in this way, it is possible to prevent the moving image data from being switched due to an erroneous operation by the user.

As described above, it is particularly preferable to be able to select the moving image data of the switching destination according to the direction of the swipe operation when the whole moving image image data includes three or more subjects. For example, when the third subject is included on the right side of the subject C1 shown in FIG. 1 (a), the display control unit 153 responds to the left swipe operation in the state of FIG. 1 (b). , The display unit 12 displays the third moving image data including the third subject. The display control unit 153 displays the second moving image data including the second subject C2 on the display unit 12 in response to the fact that the swipe operation for the right direction is performed twice while the third moving image data is displayed. Display. By operating the display control unit 153 in this way, when three or more subjects are included in the overall moving image data Z, the user can easily switch to the moving image data including the subject to be viewed. Can be done.

The display control unit 153 may display information indicating the positional relationship of a plurality of subjects in the overall moving image data Z on the display unit 12 so that the user can perform a swipe operation in an appropriate direction. As an example, the display control unit 153 displays icon images corresponding to each of a plurality of subjects in an arrangement corresponding to the positional relationship of each of the plurality of subjects. By displaying such an icon image by the display control unit 153, it is possible to perform a swipe operation for making the user see a desired subject without mistake. In addition, instead of switching the moving image data by the swipe operation, the display control unit 153 may switch to the moving image data including the subject corresponding to the selected icon image because the predetermined icon image is selected. ..

While the display control unit 153 is displaying the first moving image data on the display unit 12, the time during which the moving image data to be displayed on the display unit 12 can be switched from the first moving image data to the second moving image data. Information indicating that it is a band may be displayed on the display unit 12. The display control unit 153 causes the display unit 12 to display an icon image indicating that the second moving image data can be switched to, for example, in a time zone in which the second moving image data can be displayed. By operating the display control unit 153 in this way, it is possible to prevent the user from swiping even though the second moving image data cannot be displayed.

While the display control unit 153 is displaying the first moving image data or the second moving image data on the display unit 12, the display control unit 153 has a first operation image for setting a reproduction target time of the first moving image data, and a first operation image. The display unit 12 may display a scroll bar including a second operation image indicating a displayable time zone of the second moving image data. FIG. 4 is a diagram showing an example of a screen on which a scroll bar is displayed.

The first moving image data is displayed on the screen shown in FIG. Further, on the screen shown in FIG. 4, the operation image G0 indicating that the displayable time zone of the first moving image data is from 0 to 30:00 and the reproduction target time of the first moving image data are set. A first operation image G1 for the purpose and a second operation image G2 indicating a displayable time zone of the second moving image data are included. The user can change the time when the first moving image data is displayed by moving the position of the first operation image G1.

The display control unit 153 receives the second moving image data when the operation receiving unit 152 receives a swipe operation to the right while the first moving image data is displayed at the time when the second operation image G2 is shown. Switch to. The display control unit 153 switches the moving image data when the operation receiving unit 152 receives a swipe operation to the right while the first moving image data is displayed at a time when the second operation image G2 is not shown. do not have. In this case, the display control unit 153 may display a warning such as "There is no image to be switched".

The display control unit 153 may further display information for supporting the swipe operation. The display control unit 153 may display, for example, an image of an arrow indicating the direction in which the swipe operation should be performed. Further, the display control unit 153 may display the name of the subject displayed by swiping in the direction of the arrow together with the image of the arrow. By displaying the image of the arrow and the name of the subject by the display control unit 153, it becomes easier for the user to determine whether or not it is better to switch the moving image data, and it becomes easier to operate in the correct direction.

When the operation reception unit 152 receives a predetermined operation in the state shown in FIG. 4, the display control unit 153 displays either the first moving image data or the second moving image data on the display unit 12. The third operation image G3 for selecting whether to display may be displayed on the display unit 12. The predetermined operation is an operation for displaying the moving image data at a time when the first moving image data or the second moving image data can be displayed, and is, for example, an operation of touching the second operation image G2.

FIG. 5 is a diagram showing a state in which the user touches the second operation image G2. In the time zone shown in the second operation image G2, the display control unit 153 can display either the first moving image data or the second moving image data. In this case, the display control unit 153 cannot determine whether the user wants to see the first moving image data at the time specified by the user or the second moving image data at the time. Therefore, the display control unit 153 includes an image for selecting the first moving image data which is the main moving image data and an image for selecting either the second moving image data which is the sub moving image data. 2 Display the operation image G3.

In FIG. 5A, the "main" is shown by a solid line and the "sub" is shown by a broken line, so that the user can recognize that the first moving image data is displayed. There is. When the user selects "sub" in this state, the display control unit 153 switches to the second moving image data including the subject C2 as shown in FIG. 5B. By operating the display control unit 153 in this way, the user can easily specify the moving image data to be viewed even at the time when a plurality of moving image data can be displayed. The display control unit 153 may display the name of the first subject C1 and the name of the second subject C2, respectively, instead of the "main" and the "sub" in FIG.

[Record display time]
The display control unit 153 may store the time when the first moving image data is displayed on the display unit 12 and the time when the second moving image data is displayed on the display unit 12 in the storage unit 14. In this case, the display control unit 153 selects based on the result of referring to the time stored in the storage unit 14 when displaying the first moving image data or the second moving image data on the display unit 12 from the next time onward. The moving image data of the time may be displayed on the display unit 12.

The display control unit 153 displays, for example, the first moving image data from 0 minutes to 5 minutes, and stores the storage unit 14 that the second moving image data is displayed from 5 minutes to 10 minutes, and then the operation reception unit. When the 152 starts the operation of reproducing the moving image data, the moving image data displayed at the last time from the time of the last stored time (10 minutes) (the second moving image in the above case). Data) is started to be displayed. By operating the display control unit 153 in this way, when the user interrupts the viewing of the moving image data and then resumes the viewing, the viewing can be resumed in the same state as before the interruption.

The display control unit 153 is one of the first moving image data and the second moving image data based on the time stored in the display unit 12 when the user performs an operation for resuming viewing of the moving image data. Within a predetermined period before the viewing of the moving image data is interrupted, the moving image data that has been viewed for a longer time may be displayed on the display unit 12. The predetermined period is, for example, a period from the start to the end of viewing of the entire moving image data Z including the first moving image data and the second moving image data that have been viewed. By operating the display control unit 153 in this way, for example, even if the moving image data that was being viewed immediately before the interruption is not the moving image data that includes the subject that the user wants to see, the user can see it. It is possible to resume viewing from moving image data that includes the desired subject.

The display control unit 153 displays the first moving image data when the operation receiving unit 152 accepts the switching operation after switching the moving image data to be displayed on the display unit 12 from the first moving image data to the second moving image data. The display unit 12 may display an operation screen for the user to specify from what point in time to restart. The following two time points are assumed as the time points for resuming the display of the first moving image data.
(1) Time when the first moving image data is switched to the second moving image data immediately before (2) Time when the second moving image data is switched to the first moving image data

Therefore, the display control unit 153 starts displaying from the first moving image data corresponding to the first time at the time when the first moving image data is switched to the second moving image data, or the display is started from the first moving image data. The display unit 12 may display an operation screen for selecting whether to start the display from the first moving image data corresponding to the second time at the time of switching to the moving image data. When the user selects the former, the display control unit 153 starts the display from the first moving image data corresponding to the first time, and when the user selects the latter, the first moving image data corresponding to the second time. The display starts from. By operating the display control unit 153 in this way, when the user wants to see the first moving image data while looking at the second moving image data, the user can easily obtain the first moving image data. It will be possible to see.

The display control unit 153 stores, for example, the reproduction position of the first moving image data at the time when the switching operation is performed, and when the user selects the latter, the first moving image is stored from the stored position. Start playing data. The display control unit 153 constantly reproduces the first moving image data, and when the switching operation is accepted, the display control unit 153 may switch to display the reproduced first moving image data.

[Operation flow of image display device 1]
FIG. 6 is a flowchart showing the operation flow of the image display device 1. The flowchart shown in FIG. 6 starts from the time when the user performs an operation for starting viewing of the moving image data.

When the operation reception unit 152 accepts the operation for starting viewing, the data acquisition unit 151 starts acquisition of moving image data from the image distribution device 2 (S11). Then, the display control unit 153 starts displaying the first moving image data set in the main moving image data to be displayed by default (S12).

In this state, the display control unit 153 monitors whether or not the swipe operation has been performed in cooperation with the operation reception unit 152 (S13). When the swipe operation is performed (YES in S13), the display control unit 153 determines whether or not the direction of the swipe operation corresponds to the second subject C2 (S14). Further, the display control unit 153 determines whether or not the second moving image data can be displayed in the time zone when the direction of the swipe operation is the direction corresponding to the subject C2 (YES in S14). ).

When the display control unit 153 determines that the second moving image data is in the displayable time zone (YES in S15), the display control unit 153 switches to the second moving image data (S16). When the display control unit 153 determines NO in any of S13, S14, and S15, the display unit 12 continuously displays the first moving image data without switching to the second moving image data.

While the second moving image data is displayed on the display unit 12, the display control unit 153 monitors whether or not a swipe operation is performed (S17), and when the swipe operation is performed (YES in S17). , It is determined whether the direction of the swipe operation corresponds to the first subject C1 (S18). When the direction of the swipe operation is the direction corresponding to the subject C1 (YES in S18), the display control unit 153 determines whether or not the time zone in which the second moving image data can be displayed has ended (S19). ).

When the display control unit 153 determines that the time zone has not ended (NO in S19), the display control unit 153 continuously displays the second moving image data on the display unit 12. On the other hand, when the display control unit 153 determines that the time zone has ended (YES in S19), the display control unit 153 confirms whether or not the user has performed an operation for ending the display processing of the moving image data (S20). ). When the display control unit 153 determines that the operation for ending the display processing of the moving image data has not been performed (NO in S20), the display control unit 153 returns the processing to S12 and switches to the first moving image data.

[Modification example]
In the above description, the operation that the data acquisition unit 151 acquires the second moving image data in advance at the time when the display control unit 153 displays the first moving image data on the display unit 12 is exemplified. The timing at which the data acquisition unit 151 acquires the second moving image data is not limited to this. The display control unit 153 accepts an operation of whether or not to view the second moving image data associated with the first moving image data when the operation receiving unit 152 accepts the operation of viewing the first moving image data. The screen for this purpose may be displayed on the display unit 12. Then, the data acquisition unit 151 may acquire the second moving image data from the image distribution device 2 when the operation receiving unit 152 receives the operation for viewing the second moving image data.
By operating the control unit 15 in this way, it is not necessary for the storage unit 14 to store a large amount of the second moving image data, so that the capacity of the storage unit 14 can be reduced.

The data acquisition unit 151 switches when displaying information (for example, an image of a slide bar or an arrow) indicating that the display control unit 153 can accept a swipe operation while the first moving image data is being played back. It may be determined whether or not the second moving image data to be displayed later has been acquired. Then, when it is determined that the second moving image data has not been acquired, the data acquisition unit 151 acquires the second moving image data from the image distribution device 2. The display control unit 153 stops the reproduction of the first moving image data until the data acquisition unit 151 completes the acquisition of the second moving image data, stores the stopped time, and stores the stopped time, and the data acquisition unit 151. When the second moving image data is acquired, the reproduction of the second moving image data may be started from the position corresponding to the stored time.

[Effect of image display device 1]
As described above, the data acquisition unit 151 acquires the first moving image data and the second moving image data associated with the common time information, and the display control unit 153 displays the first moving image data in the display unit 12. When the operation reception unit 152 accepts the switching operation while displaying in, the moving image data to be displayed on the display unit 12 corresponds to the same time as the time of the first moving image data to the first moving image data. Switch to the second moving image data. Since the image display device 1 is configured in this way, the second moving image data including the subject that the user wants to see is included while viewing the first moving image data. You will be able to easily view the moving image data.

The present invention is also suitable for moving image data of sports in which a plurality of athletes appear. When the image display device 1 displays, for example, moving image data of a soccer game, the user can switch which team to mainly watch by swiping or touching the image of the arrow.

The image display device 1 may switch and display a plurality of moving image data corresponding to a plurality of athletes photographed by a plurality of cameras. For example, when the swipe operation or the touch operation to the image of the arrow is performed in the second operation image G2 shown in FIG. 5, the display control unit 153 switches to the moving image data captured mainly by the player corresponding to the operation content. In this case, even if the display control unit 153 automatically displays the moving image data corresponding to the player selected by the previous operation in a time zone in which there is a plurality of moving image data corresponding to the plurality of players. good. The display control unit 153 may reproduce the moving image data of the scene in which the player selected by the user appears in a connected state. By operating the display control unit 153 in this way, the user can easily view the moving image data centered on the favorite player.
