  A plurality of contents stored in such a photographing device may include moving image content and still image content obtained by photographing the same scene. For example, when shooting the same scenery as a video camera while shooting the same scenery as a still image, or when traveling with multiple people, one person who is a video camera is shot as a video. In some cases, another person may shoot the same person as a still image with a digital camera.

  In this way, related video content and still image content that shot the same scene are stored in multiple shooting devices, and the following procedure is necessary when playing back related content. .

  First, with a plurality of shooting devices connected to the playback device, the user selects one shooting device from the menu screen or the like, and selects and plays back one content from the content list display screen stored in the selected shooting device. To do. When the reproduction of the selected content is completed, the user selects the same photographing device or another photographing device, and selects and reproduces one of the contents in the selected photographing device. Whether or not the content is related to shooting the same scene is not known unless it is played back, and when the content in a different shooting device is played back in order to search for the related content, the user takes a picture. It was necessary to perform an operation to select a device.

  In order to reduce the time and effort of the operation described above, in Patent Document 1, content in a photographing device is stored in a playback device, and during playback of content selected from the stored content, playback from other content is being performed. A technique has been proposed in which content whose shooting time overlaps with content is detected and associated with the content being reproduced, the result is notified to the user, and the user can switch the content being reproduced.

In addition, the control unit 11 comprehensively controls each unit provided in the content reproduction device 1.

  The operation input unit 12 receives a user operation and outputs an operation signal based on the operation to the control unit 11.

  Next, the operation of the content reproduction apparatus 1 will be described. For convenience of explanation, in the following, two photographing devices A and B are connected to the content reproduction apparatus 1, moving image content is stored in the photographing device A, and still image content is stored in the photographing device B. An example will be described.

  When the photographing devices A and B are connected to the content reproduction device 1, the connected device control unit 2 notifies the data analysis unit 3 that the photographing devices A and B are connected to the content reproduction device 1.

  Upon receiving the notification from the connected device control unit 2, the data analysis unit 3 accesses each content stored in the photographing devices A and B via the connected device control unit 2, and analyzes the file data of each content. The above-mentioned file path information, shooting position information, shooting direction information, subject distance information, shooting date / time information, shooting device information, and type information are acquired. The data analysis unit 3 calculates subject position information based on the photographing position information, the photographing direction information, and the subject distance information. Then, the data analysis unit 3 allocates content IDs for each content, and stores them in the content information storage unit 4 in association with the various types of information as shown in FIG.

  In the content reproduction apparatus 1, in order to associate and reproduce the content that is predicted to photograph the same scene in the connected photographing devices A and B, it is necessary to set an association condition.

  Association condition setting will be described. When a signal indicating an association condition setting instruction is input through the operation input unit 12 by the user's operation, the control unit 11 generates GUI data of the association reproduction setting screen and controls the video composition unit 8 to perform association. A playback setting screen is displayed on the display unit 9.

  An example of the associated reproduction setting screen displayed here is shown in FIG. As shown in FIG. 3, the association reproduction setting screen 20 displays an association setting field 21, a reference device setting field 22, an effective time setting field 23, and an effective range setting field 24.

  The association setting field 21 is used to select whether to make the association valid or invalid. When “valid” is selected, the association according to the setting item is valid, and when “invalid” is selected, no association is performed.

  The reference device setting field 22 is used to select an associated reference device from the photographing devices A and B connected to the content reproduction apparatus 1.

  The valid time setting field 23 is for setting a valid time for association based on the shooting date and time. The shooting date and time of the content of the reference device set in the reference device setting field 22 (shooting end date and time in the case of moving image content) and the shooting date and time of the content of the shooting device other than the reference device connected to the content playback device 1 ( If it is within the effective time set in the effective time setting field 23 in the case of moving image content, the content of the other image capturing device is associated with the content of the reference device.

  The effective range setting field 24 is used to set a reference position that is a reference for association and a distance that is an effective range for association. As shown in FIG. 3, the reference position for association can be selected from four “shooting position and / or subject position”, “shooting position and subject position”, “shooting position”, and “subject position”.

  When “shooting position and / or subject position” is selected, content that has at least one of the shooting position and the subject position within the effective range is compared with the content of the reference device. It becomes the setting to associate. That is, content corresponding to the following (1) to (3) among the content of other photographing devices is associated with the content of the reference device. (1) Content whose shooting position is within the effective range with respect to the shooting position of the content of the reference device and whose subject position is within the effective range with respect to the subject position of the content of the reference device, (2) The shooting position of the content of the reference device Content whose subject position is within the effective range with respect to the photographing position and the subject position is outside the effective range with respect to the subject position of the content of the reference device, (3) The photographing position is outside the effective range with respect to the photographing position of the content of the reference device and the subject position is Content that is within the effective range for the subject position of the content of the reference device.

  When “shooting position and subject position” is selected, among the contents of other photographing devices, the photographing position is within a predetermined range with respect to the photographing position of the reference device content, and the subject position is relative to the subject position of the reference device content. The content within the predetermined range is set to be associated with the content of the reference device.

  When “shooting position” is selected, the content in which the shooting position is within a predetermined range with respect to the shooting position of the content of the reference device among the content of other shooting devices is set to be associated with the content of the reference device.

  When “Subject position” is selected, the content in which the subject position is within a predetermined range with respect to the subject position of the content of the reference device among the content of other photographing devices is set to be associated with the content of the reference device.

  The user can set each setting item by operating the operation input unit 12 on the associated reproduction setting screen 20. When each setting item is set by a user operation, the control unit 11 stores the setting contents of the association condition in a memory (not shown).

  When the association condition is set, the control unit 11 performs the process of associating the contents stored in the photographing devices A and B based on the set association condition and the content information stored in the content information storage unit 4. Do. It is not necessary to set the association condition every time the photographing devices A and B are connected. When the photographing devices A and B are connected to the content reproduction apparatus 1 in the past, the association condition is set and the contents are set. If stored in the memory, the control unit 11 performs an association process using the stored association condition.

  An example of association will be described. FIG. 4 is a diagram illustrating an example of the shooting position of content in the shooting devices A and B. In FIG. 4, shooting positions M1-1 to M1-3, M2-1 to M2-3, M3-1 to M3-3 of the shooting apparatus A indicate shooting positions of one moving image content m1, m2, and m3, respectively. .

  The moving image contents m1 to m3 are moving image contents shot by the shooting device A while moving by the user. The shooting positions M1-1 and M1-3 respectively indicate the shooting positions at the shooting start date and time and the shooting end date and time of the moving image content m1, and the shooting position M1-2 indicates shooting position information and the like at predetermined time intervals during the shooting period. The shooting position when recorded in the file m1 is shown.

  The shooting positions S1 to S8 of the shooting device B indicate the shooting positions of the still image contents s1 to s8. The shooting order in the shooting device A is the order of the moving image contents m1 to m3, and the shooting order in the shooting device B is the order of the still image contents s1 to s8.

  Here, it is assumed that the reference device is set as the photographing device A, the effective time is 0 minute, the association reference position is “photographing position”, and the effective range is 200 m. A circle surrounding each photographing position in FIG. 4 indicates an effective range having a radius of 200 m.

  In FIG. 4, the shooting position S1 is within the effective range of the shooting position M1-2, the shooting positions S2 and S3 are within the effective range of the shooting position M1-3, and the shooting position is within the effective range of the shooting position M3-1. There are S7 and S8. However, the photographing positions S4 to S6 are not included in any effective range of the photographing positions M1-1 to M1-3, M2-1 to M2-3, and M3-1 to M3-3 of the photographing apparatus A. Therefore, as shown in FIG. 5, the still image contents s1 to s3 are associated with the moving image content m1, and the still image contents s7 and s8 are associated with the moving image content m3, while the still image contents s4 to s6 are associated with the moving image contents m1 to m3. Is not associated with any of the

  The control unit 11 stores association information indicating the correspondence of the content associated as described above in the content information storage unit 4. FIG. 6 is a diagram showing the contents of the association information. As shown in FIG. 6, the association information includes the content ID and shooting date / time information of the content of the shooting device A that is the reference device, and the content ID and shooting date / time information of the content of the shooting device B associated with the content of the shooting device A. including.

  By the way, in the moving image content shot while the user is moving, as shown in FIG. 7, the shooting position M1-1 corresponding to the shooting position information recorded every predetermined time during shooting of one moving image content m1 by the shooting device A. , M1-2 and M1-3 may be greatly separated. In FIG. 7, the photographing position S1 of the photographing apparatus B between the photographing positions M1-1 and M1-2 of the photographing apparatus A and the photographing position S2 between the photographing positions M1-2 and M1-3 are the positions of the photographing apparatus A. Since it is not included in any effective range of the shooting positions M1-1 to M1-3, the moving image content m1 and the still image contents s1 and s2 corresponding to the shooting positions S1 and S2 are not associated with each other.

  Therefore, in one moving image content, the range of the locus 26 of the effective range corresponding to the locus 25 of continuous shooting positions is regarded as the effective range. As a result, the still image contents s1 and s2 corresponding to the shooting positions S1 and S2 as shown in FIG. 7 are also associated with the moving image content m1 corresponding to the shooting positions M1-1 to M1-3.

  In the example shown in FIG. 8, the shooting position of the shooting device B within the effective range with respect to the shooting positions M1-1 to M1-3 of the shooting device A is only one of the shooting positions S1. The position S2 is within the effective range of the shooting position S1, and the shooting position S3 is within the effective range of the shooting position S2. In such a case, together with the still image content s1 corresponding to the shooting position S1, the still image contents s2 and s3 corresponding to the shooting positions S2 and S3 are also the moving image content m1 corresponding to the shooting positions M1-1 to M1-3. To be associated with.

  As described above, the effective range of the imaging position S1 of the imaging device B that is within the effective range with respect to the imaging positions M1-1 to M1-3 of the imaging device A is the imaging positions M1-1 to M1-3 of the imaging device A. The effective range of the imaging position S2 within the effective range of the imaging position S1 and the effective range of the imaging position S3 within the effective range of the shadow position S2 are also considered as the effective range of the imaging apparatus A. Considered the effective range of M1-3. Since the shooting position S4 does not fall within the effective range of the shooting positions S1 to S3, the still image content s4 corresponding to the shooting position S4 is not associated with the moving image content m1.

  After the association processing, when a signal instructing content list display based on a user operation is input via the operation input unit 12, the control unit 11 generates GUI data of the content list display screen, and the video composition unit 8 The content list display screen is controlled to be displayed on the display unit 9.

  An example of the content list display screen displayed here is shown in FIG. As shown in FIG. 9, the content list display screen 30 displays the photographing device from which the content is stored, the photographing date and time, and the photographing position of the content.

  In the example of FIG. 9, the moving image content and the still image content are separated, and the moving image content list is displayed by selecting the moving image tab 31, and the still image content list (not shown) is selected by selecting the still image tab 32. ) Is displayed. When the content list display screen 30 is displayed, the control unit 11 acquires representative images of moving image content and images of still image content from the photographing devices A and B, and displays these images as thumbnails. Good.

  On the content list display screen 30, the user moves the selection frame 33 for selecting content to be reproduced to a desired position and operates to determine the content selected by operating the operation input unit 12. The start of playback can be instructed.

  When an instruction signal for reproducing the moving image content m1 corresponding to the shooting positions M1-1 to M1-3 in FIGS. 4 and 5 is input by the user operation, the control unit 11 determines the moving image content based on the file path information. The connected device control unit 2 is controlled so that the content data of m1 is acquired from the photographing device A and supplied to the demultiplexer 5.

  Next, the control unit 11 extracts the compressed video data and the compressed audio data from the content data of the moving image content m1 by the demultiplexer 5, decodes the compressed video data by the video decoder 6, and the audio decoder 7 Control is performed to decode the compressed audio data.

  The control unit 11 supplies the video data decoded by the video decoder 6 to the display unit 9 via the video synthesis unit 8 to display the video, and the audio data decoded by the audio decoder 7 is output to the audio output unit. 10 to output sound.

  In the examples of FIGS. 4 and 5, as described above, the still image contents s1 to s3 are associated with the moving image content m1. Therefore, when the time corresponding to the shooting date and time of the still image content s1 comes during the reproduction of the moving image content m1 as described above, the control unit 11 reproduces the moving image content m1 for a predetermined time (for example, several seconds). ), The content data of the still image content s1 is acquired from the photographing device B through the connected device control unit 2, and is supplied to the display unit 9 through the video composition unit 8 to be supplied to the video of the still image content s1. Is displayed in full screen.

  When a predetermined time elapses after the reproduction of the moving image content m1 is paused and the display of the still image content s1 is started, the control unit 11 ends the display of the still image content s1 and restarts the reproduction of the moving image content m1. . Thereafter, for the still image contents s2 and s3, when the time corresponding to each shooting date / time comes, the control unit 11 pauses the reproduction of the moving image content m1 and displays the still image contents s2 and s3 for a predetermined time. Display.

  Similarly to the case where the moving image content m1 is reproduced, when the moving image content m3 corresponding to the shooting positions M3-1 to M3-3 is reproduced, the still image contents s7 and s8 associated with the moving image content m3 are Playback and display is performed for a predetermined time at a time corresponding to the shooting date and time, and playback of the moving image content m3 is paused.

  It should be noted that the video of the still image content may be displayed on a part of the playback screen of the video content without pausing the playback of the video content.

  In addition, when moving image contents having overlapping times in shooting date and time are associated with each other, two moving image contents are simultaneously displayed on the display unit 9 in a two-screen display at the overlapping time.

  Next, another example of association will be described. FIG. 10 is a diagram illustrating an example of content shooting positions and subject positions in the shooting devices A and B. FIG.

  In FIG. 10, subject positions M′1-1 to M′1-3 and M′2-1 to M′2-3 of the photographing apparatus A indicate subject positions of the moving image contents m1 and m2, respectively. Further, subject positions S′1 to S′6 of the photographing device B indicate subject positions of the still image contents s1 to s6, respectively. Other symbols are the same as those in FIG.

  Here, it is assumed that the reference device is set to the photographing device A, the effective time is 0 minute, the association reference position is “photographing position and subject position”, and the effective range is 200 m.

  In FIG. 10, for example, for the still image content s1, the shooting position S1 is within the effective range of the shooting position M1-2 of the moving image content m1, and the subject position S′1 is the subject position M′1 of the moving image content m1. -2 in the effective range, it is associated with the moving image content m1.

  On the other hand, for example, for the still image content s2, the shooting position S1 is within the effective range of the shooting position M1-3 of the moving image content m1, but the subject position S′1 is the subject position M′1-1 of the moving image content m1. Since it is not included in any effective range of M′1-3, it is not associated with the moving image content m1.

  FIG. 11 shows the result of associating the still image contents s1 to s6 with the moving image contents m1 and m2 in this way. As shown in FIG. 11, the still image contents s1 and s3 corresponding to the shooting positions S1 and S3 are associated with the moving image content m1 corresponding to the shooting positions M1-1 to M1-3, but the shooting positions S2, S4 to S6. The still image contents s2, s4 to s6 corresponding to are not associated with any of the moving image contents m1 and m2.

  In the example of FIG. 10, a case will be described in which only the reference position condition among the association conditions is changed to “shooting position and / or subject position”.

  In this case, in FIG. 10, for example, for the still image content s2, the subject position S′2 is not included in any effective range of the subject positions M′1-1 to M′1-3 of the moving image content m1. Since the shooting position S2 is within the effective range of the shooting position M1-3 of the moving image content m1, it is associated with the moving image content m1.

  For the still image content s4, the shooting position S4 is not included in any effective range of the shooting positions M2-1 to M2-3 of the moving image content m2, but the subject position S′4 is the subject of the moving image content m2. Since it is within the effective range of the position M′2-1, it is associated with the moving image content m2.

  On the other hand, for example, for the still image content s5, the shooting position S5 is not included in any effective range of the shooting positions M1-1 to M1-3 and M2-1 to M2-3 of the moving image contents m1 and m2. The subject position S′5 is not included in any effective range of the subject positions M′1-1 to M′1-3 and M′2-1 to M′2-3 of the moving image contents m1 and m2. , It is not associated with any of the moving image contents m1 and m2.

  Note that the effective range of the subject positions M′1-1 to M′1-3 and M′2-1 to M′2-3 of the moving image contents m1 and m2 is also the shooting position M1 described with reference to FIG. Similarly to the effective range of 1 to M1-3, the range of the trajectory of the effective range corresponding to the trajectories of the consecutive subject positions M'1-1 to M'1-3, M'2-1 to M'2-3. Is also considered to be an effective range.

  Similarly to the example shown in FIG. 8, the effective range of the subject position of the photographing device B that is within the effective range with respect to the subject position of the photographing device A is regarded as the effective range of the subject position of the photographing device A. To do.

  FIG. 12 shows the result of associating the still image contents s1 to s6 with the moving image contents m1 and m2 in this way. As shown in FIG. 12, the still image contents s1 to s3 corresponding to the shooting positions S1 to S3 are associated with the moving image content m1 corresponding to the shooting positions M1-1 to M1-3 and correspond to the shooting positions S4 and S6. The still image contents s4 and s6 are associated with the moving image content m2 corresponding to the shooting positions M2-1 to M2-3, but the still image content s5 corresponding to the shooting position S5 is associated with both the moving image contents m1 and m2. Not.

  Next, an example of association when the valid time is set will be described with reference to FIGS. Here, it is assumed that the reference device is set as the photographing device A, the effective time is 30 minutes, the reference position of the association is “shooting position”, and the effective range is 200 m as the association condition.

  In FIG. 13, the shooting positions S1 to S4 corresponding to the still image contents s1 to s4 of the shooting device B are the moving image content m1 and the shooting positions M2-1 and M1-2 corresponding to the shooting positions M1-1 and M1-2 of the shooting device A, respectively. It is not included in any effective range of the moving image content m2 corresponding to M2-2.

  On the other hand, the shooting dates and times of the still image contents s1 and s2 corresponding to the shooting positions S1 and S2 are 9:20 and 9:30, respectively, and are within the valid time (up to 9:30) of the moving image content m1. For this reason, as shown in FIG. 14, the still image contents s1 and s2 corresponding to the shooting positions S1 and S2 are associated with the moving image content m1 corresponding to the shooting positions M1-1 and M1-2. The still image contents s3 and s4 corresponding to the shooting positions S3 and S4 are not associated with each other because they do not fall within any valid time of the moving image contents m1 and m2.

  Here, as in the case of the still image contents s1 and s2 in the examples of FIGS. 13 and 14, the movie contents m1 are associated with the movie contents m1. The still image contents s1 and s2 are continuously reproduced and displayed immediately after the reproduction of the content m1.

  In addition, when a plurality of still image contents are reproduced like the still image contents s1 and s2, a plurality of still image contents are displayed while being switched at regular intervals in order of shooting date and time, for example, as a slide show.

  As described above, according to the present embodiment, the shooting position information, shooting direction information, and subject distance information of the content stored in the shooting devices A and B from the shooting devices A and B connected to the content reproduction apparatus 1 are described. , Acquisition of shooting date / time information, etc., calculation of subject position information from the shooting position information, shooting direction information, and subject distance information, and using the shooting position information, subject position information, and shooting date / time information, the shooting devices A, B Since the content stored in the reference device selected from the above and the content stored in another shooting device are played back in association with each other, if the same scene is shot from the content stored in the plurality of shooting devices A and B Predicted content can be related and reproduced with high accuracy.
