The data selection unit 71 is a plurality of moving image data to be included in the moving image set in a state where a plurality of moving image data (more precisely, thumbnail images thereof) stored in the moving image storage unit 61 are displayed as a list on the output unit 18. Let the user select
In addition, after one moving image data is selected, the data selection unit 71 determines moving image data that is inappropriate for simultaneous reproduction with the selected moving image data for the remaining moving image data, and the moving image data determined to be inappropriate A plurality of moving image data is displayed in a list on the output unit 18 in a state in which selection of the item is prohibited.

  The reproduction condition designating unit 43 arbitrarily designates a reproduction condition for simultaneously reproducing a plurality of moving image data included in the moving image set generated by the set generating unit 42 based on an instruction operation of the input unit 17 by the user.

The playback condition specified by the playback condition specifying unit 43 refers to various conditions relating to playback of each of a plurality of moving image data included in the predetermined moving image set, which is effective only for the predetermined moving image set.
Specifically, for example, when the first moving image data is included in common to a plurality of moving image sets, the first moving image data is determined according to the difference in the moving image data of the other party combined with the first moving image data. The reproduction condition designating unit 43 designates the reproduction conditions for a plurality of moving image sets so that the frame positions for matching the reproduction timings of the video sets differ.
More specifically, for example, the first moving image data obtained by photographing a golf swing as a model constitutes a plurality of moving image sets with a plurality of moving image data obtained by photographing a plurality of golf swings to be compared. The frame position corresponding to any one of the plurality of check points specific to the golf swing is the check point to be compared in the opponent video data. The reproduction condition designating unit 43 designates the reproduction conditions for a plurality of moving image sets so as to be different depending on the difference.

Here, as the playback condition specified by the playback condition specifying unit 43, for example, a condition for matching the playback timings of a plurality of moving image data to be played back simultaneously can be employed.

In addition, when the movie A is placed horizontally and the movie B is placed vertically, and the playback control device 1 is oriented horizontally, the movies A and B are arranged side by side, while the playback control device 1 is placed vertically. When facing the direction, the arrangement conditions of the movies A and B are set so that the movies A and B are arranged in the vertical direction.

  Further, for example, when the shooting direction is horizontal for both movies A and B and the automatic vertical / horizontal rotation is “OFF”, both movies A and B are horizontal as shown in the second row and first column of FIG. And the arrangement conditions of the movies A and B are set so that the movies A and B are arranged in the horizontal direction regardless of the direction of the playback control device 1.

  Also, for example, when the shooting direction of both movies A and B is vertical, and the automatic vertical / horizontal rotation is “OFF”, both movies A and B are vertically set as shown in the second row and second column of FIG. And the arrangement conditions of the movies A and B are set so that the movies A and B are arranged in the horizontal direction regardless of the direction of the playback control device 1.

  Further, for example, when the shooting direction of the movie A is vertical and the shooting direction of the movie B is horizontal, and the vertical and horizontal automatic rotation is “OFF”, the second row and the third column in FIG. In addition, the arrangement conditions of each of the movies A and B are such that the movie A is arranged vertically and the movie B is arranged horizontally and the movies A and B are arranged in the horizontal direction regardless of the direction of the playback control device 1. Is set.

  Further, for example, when the shooting direction of the movie A is horizontal and the shooting direction of the movie B is vertical, and the automatic vertical / horizontal rotation is “OFF”, the second row and the fourth column in FIG. In addition, the arrangement conditions of each of the movies A and B are such that the movie A is arranged horizontally and the movie B is arranged vertically, and the movies A and B are arranged in the horizontal direction regardless of the direction of the playback control device 1. Is set.

  Returning to FIG. 2, the simultaneous playback information registration unit 44 generates simultaneous playback information in which the information of the moving image set set by the set generation unit 42 and the playback condition specified by the playback condition specifying unit are associated with each other. Store (register) in the simultaneous reproduction information storage unit.

  When the playback condition of the movie set to be played is specified, the simultaneous playback control unit 45 is configured to store a plurality of movie data included in the movie set under the playback condition stored in association with the specified movie set. Are controlled to be reproduced simultaneously on the display of the output unit 18.

  As described above, the number of moving image data included in the moving image set is not particularly limited as long as it is plural, but in the following description, it is assumed that the number is two for convenience. In this case, the multi-screen playback control process is referred to as a “two-screen playback control process”.

In the two-screen playback process, the first movie and the second movie that make up the movie set generated in step S12 are in a state in which the start points are aligned based on the simultaneous playback information registered in step S15. The process of reproducing and outputting from the output part 18 is said. A specific example of the two-screen playback process will be described later.

  In step S19, the main control unit 41 determines whether or not to continue the process for another moving image set. When continuing the process for another moving image set, it is determined as YES in Step S19, and the process returns to Step S12. In this case, in steps S12 to S19, processing for a new moving image set is repeatedly executed. On the other hand, when the process for another moving image set is not continued, it is determined as NO in Step S19, and the two-screen reproduction process is ended.

Next, a specific example of the two-screen playback control process will be described with reference to FIGS.
First, the two-screen playback control process when the simultaneous playback information is not set (not generated) will be described with reference to FIGS. 6 to 13 are diagrams illustrating specific examples of the two-screen playback control process when the simultaneous playback information is not set.
When the PLAY menu is displayed on the display of the output unit 18 (not shown), when the right key of the cursor key of the input unit 17 or the SET key is pressed by the user in the first layer of the PLAY menu, the output unit The two-screen list screen shown in FIG. 6 is displayed on the 18 display.

In the two-screen list screen of FIG. 6, it is shown that simultaneous reproduction information is not set (generated) in unselected display and thumbnail display without an image. In this two-screen list screen, a list can be created up to 40 cases / card.
When the reproduction key or setting key of the input unit 17 is selected based on a user operation, the main control unit 41 outputs an error sound from the speaker of the output unit 18 without displaying anything.
When the MOVIE key of the input unit 17 is selected based on the user's operation while the two-screen list screen is displayed, the two-screen selection screen (selection screen for a movie to be reproduced on two screens) in FIG. 7 is output. It is displayed on the display of the unit 18.

In the two-screen selection screen of FIG. 7, only the movie thumbnail is displayed on the display of the output unit 18. In the state of FIG. 7, no movie has been selected yet.
In the example of FIG. 7, the movie data temporarily selected by the user operating the cursor keys (right key, left key, up key, down key) of the input unit 17 is surrounded by a cursor frame. It is represented by
On the two-screen selection screen in FIG. 7, a movie can be displayed as a single image with the zoom lever of the input unit 17. By performing the single display, it is possible to confirm individual time stamp display (time stamp is always displayed). A specific example of performing single display will be described with reference to FIG.
If the movie is completed without selecting any movie on the two-screen selection screen shown in FIG. 7, the list is deleted and the processing returns to FIG. 6, and the two-screen list screen is displayed again on the display.
When a desired movie is selected by operating the cursor key of the input unit 17 based on the user's operation on the two-screen selection screen of FIG. 7, when the SET key of the input unit 17 is pressed based on the user's operation, FIG. As shown, any movie is selected on the two-screen selection screen.

When an arbitrary movie is selected based on the operation of the input unit 17 by the user on the two-screen selection screen of FIG. 8, a single and multi-selection screen of different types of movies is displayed in a shaded manner by OSD (on screen display). Then, it is displayed on the display that the selection is impossible (for example, refer to the thumbnail at the upper left of FIG. 8). The different types of movies are movies that are not configured in the same (or similar) format, and the main control unit 41 refers to the moving image type correspondence table in FIG. 5 and the corresponding movies are the same (or approximate). ) Determine whether the format is a type.
In addition to the video format, different types of movies can be judged, including the type of the main subject in the video and the type of motion of the subject (for example, the type of sport such as golf swing, tennis, swimming, etc.) You may make it judge by.
When the two-screen selection screen of FIG. 8 is displayed on the display, when a different kind of movie with shaded display (OSD) is selected based on the operation of the input unit 17 by the user, the main control unit 41 An error sound is output from the speaker of the output unit 18 without displaying anything on the display.

In the start point search screen of FIG. 12, the simultaneous playback control unit 45 starts movie playback from the start point. In the start point search screen of FIG. 12, the start point cannot be determined in this state unless the movie is paused. When the markers overlap, the main control unit 41 displays the position display marker on the top. In the start point search screen of FIG. 12, the simultaneous playback control unit 45 repeats playback of the movie B from the beginning to the end regardless of the position of the start point.
When the SET key is pressed on the start point search screen of FIG. 12 based on the user's operation of the input unit 17, the screen returns to the start point setting screen of FIG.
Then, when the cursor key of the input unit 17 is pressed on the start point search screen of FIG. 11, the start point of the movie B is set, and two screens are reproduced on the display as shown in FIG. The processing on the start point setting screen in FIG. 11 and the start point search screen in FIG. 12 corresponds to the processing in step S14 in the two-screen playback control processing.

  In the during-reproduction screen of FIG. 13, the simultaneous reproduction control unit 45 immediately reproduces the movie A and the movie B when it is designated to immediately execute the two-screen simultaneous reproduction process after setting the start point. At the same time from the start point. When playback of both movie A and movie B is finished, playback of the movie is paused. In this case, the simultaneous playback control unit 45 pauses the playback of one (for example, movie A) movie until the other (for example, movie B) movie playback ends. When the movie playback is finished, a two-screen playback editing screen is displayed on the display (not shown). If “to the main screen” is selected based on the operation of the input unit 17 by the user while the two-screen playback / editing screen is displayed, the processing transitions to the processing of the two-screen list screen in FIG.

When “(right) movie reselection” is selected based on the operation of the input unit 17 by the user, the process transitions to the two-screen selection screen process of FIG. When the left and right movies (movie A and movie B) are changed, a transition is made to a two-screen selection screen of a target movie or a page of the target movie (a cursor is placed on the target movie). Even when the left and right movies (movie A and movie B) are changed, both movies can be changed. The process on the two-screen playback screen of FIG. 13 corresponds to the process of step S18 in the two-screen playback control process.

Heretofore, the two-screen playback control process in the case where new simultaneous playback information is generated in the list portion where the simultaneous playback information is not set has been described.
Next, a two-screen playback control process when editing the contents of the simultaneous playback information in the list portion where the simultaneous playback information is set (generated) will be described with reference to FIGS. 14 and 15 are diagrams illustrating a specific example of the two-screen playback control process when the simultaneous playback information is set.
The two-screen playback control process when the simultaneous playback information is set is basically the same process as the two-screen playback control process (FIGS. 6 to 13) when the simultaneous playback information is not set. Therefore, in the processes of FIGS. 6 to 13, a process is performed in which a screen basically similar to the two-screen playback control process when the simultaneous playback information is set is displayed on the display. However, in the two-screen list screen of the two-screen playback control process when simultaneous playback information is set, the simultaneous playback information is set in the thumbnail display and time stamp display of the set movie. On the other hand, the two-screen list screen of the two-screen playback control process when the simultaneous playback information is not set is different in that the simultaneous playback information is not set for the unselected display and the thumbnail display without an image.
Therefore, in the two-screen playback control process when the simultaneous playback information is set, a process of displaying the two-screen list screen of FIG. 14 on the display is performed instead of the process of the two-screen list screen of FIG. Further, in place of the two-screen selection screen process of FIG. 7, the two-screen selection screen process of FIG. 15 is performed.
Hereinafter, with reference to FIG. 14 and FIG. 15, the two-screen playback control process when the simultaneous playback information is set will be described.

In the two-screen list screen of FIG. 14, it is shown that simultaneous playback information is set by thumbnail display and time stamp display of the set movie. This date and time display represents a time stamp immediately after the two-screen processing. In this two-screen list screen, a list can be created up to 40 cases / card.
When the reproduction key of the input unit 17 is selected based on the user's operation, two screens are reproduced on the display as shown in FIG. When the completion key of the input unit 17 is selected based on the user's operation, the start point setting screen process is performed as shown in FIG.
If even one set of movie data is not found, the main control unit 41 outputs an error sound from the speaker of the output unit 18 without displaying anything as unselected.
When the MOVIE key of the input unit 17 is selected based on a user operation while the two-screen list screen is displayed, the two-screen selection screen (selection screen for a movie to be played back on two screens) in FIG. 15 is output. It is displayed on the display of the unit 18.

In the two-screen selection screen of FIG. 15, only the movie thumbnail is displayed on the display of the output unit 18. In the state of FIG. 15, the movie has not yet been selected. In the example of FIG. 15, the cursor is selected for the movie data when the MENU key of the input unit 17 is pressed based on the user's operation. . In the two-screen selection screen of FIG. 15, a movie can be displayed as a single image with the zoom lever of the input unit 17. By performing the single display, it is possible to confirm individual time stamp display (time stamp is always displayed). A specific example of performing single display will be described with reference to FIG.
In the two-screen selection screen of FIG. 15, when the movie is completed without selecting any movie, the list is deleted, the processing returns to FIG. 14, and the two-screen list screen is displayed again on the display.
When the desired key is selected by operating the cursor key of the input unit 17 based on the user's operation on the two-screen selection screen of FIG. 15, when the SET key of the input unit 17 is pressed based on the user's operation, FIG. As shown, any movie is selected on the two-screen selection screen.

Heretofore, the two-screen playback control process when the simultaneous playback information is set and when it is not set has been described.
Next, an example of a two-screen selection screen for switching between multi display and single display, which is performed in the two-screen reproduction control process, will be described with reference to FIG.
FIG. 16 is a diagram showing a specific example of a two-screen selection screen for switching between multi-display and single-display, which is performed in the two-screen playback control process.
As shown in FIG. 16A, when the two-screen selection multi-screen is selected, the user can switch between multi-display and single-display by operating the zoom key of the input unit 17.
For example, when the user selects the zoom key of the input unit 17 in a state where the two-screen selection multi-screen of FIG. 16A is displayed, the thumbnail at the cursor position is displayed in full screen, and the display shown in FIG. ) Two-screen selection single screen is displayed. In the two-screen selection single screen of FIG. 16 (B), it is displayed including recording information and a time stamp display for easy selection. When the user selects the zoom key of the input unit 17 while the two-screen selection single screen of FIG. 16B is displayed, the thumbnail is reduced, and the two-screen selection multi-screen of FIG. Is displayed.

  When the user presses the right of the cursor key of the input unit 17 in a state where the two-screen selection single screen of FIG. 16B is displayed, the next image is displayed on the display. Similarly, when the user presses the left of the cursor key of the input unit 17 in a state where the two-screen selection single screen of FIG. 16B is displayed, the previous image is displayed on the display.

Note that the operation target can be switched by the user operating the ring setting key of the input unit 17. In other words, whether to instruct the user to perform instruction operations such as playback, stop, slow, fast forward, etc. for two videos at the same time or only one of the videos (movie A only or movie B only). It can be set freely.
For example, the simultaneous playback control unit 45 determines that both the movie A and the movie B are operated when the simultaneous operation of two screens is set based on the pressing operation of the stop key of the input unit 17 by the user during the simultaneous playback of the two screens. Playback is paused at the same time, and when an operation for only one movie (only movie A or movie B) is set, only playback of the movie that is selecting movie A or movie B is paused.
In this case, the simultaneous playback control unit 45 resumes playback of the stopped movie when the pause state is canceled by pressing the playback key again or the like.
Note that the operation bar of the input unit 17 at the time of switching the operation target in the two-screen playback is displayed on the display.
The simultaneous playback control unit 45 pauses a movie with a short playback time until playback of the movie with a long playback time is completed when the playback time lengths of the respective movies during the two-screen playback are different. Then, when the playback of the two movies ends, the simultaneous playback control unit 45 pauses at the final scene of the two movies.
Note that when the cursor key of the input unit 17 is pressed during the pause, the simultaneous playback control unit 45 starts playback from the start point again unlike the normal pressing operation under the cursor key during the pause. To do.
When the user presses the cursor key of the input unit 17, the main control unit 41 switches between display and non-display of various software keys (operation bars) displayed on the display.

Note that the playback control apparatus 1 of the above-described embodiment can perform more advanced form analysis by comparing FHD / STD / HS movies side by side on the left and right or top and bottom.
Further, the data that can be compared is only FHD / HD / STD / HS120 / HS240 / HS480 / HS1000 (including continuous shooting files), and still images can be set out of the target. In addition, you can compare not only movies shot with the best shot for golf, but also movies recorded in normal shooting mode. However, comparisons can be limited to movies of the same type.

In the present embodiment, the selection at the time of two-screen playback can be selected any number of times and can be set so as not to limit the number of times. However, two-screen comparison of the same movie can be set to be impossible. In addition, the position display marker (movie playback position display) in two-screen playback is not displayed, but the operation bar can be displayed. Note that the operation bar can be set so that it is always displayed in a normal manner without corresponding to the vertical placement of the operation bar.
When another combination (hereinafter, a list) is created using a movie with a start point set, the start point to be created can be created based on the set start point. In this case, editing of the start point can be skipped.
Note that even if the start point is re-edited, it can be set so that it does not affect the start point of the same movie in another list. When a movie having a plurality of start points is used, the movie can be set based on the last set start point.

In addition, when a movie that has been played back on two screens (with a start point set) is played back on a single screen, the start point can be ignored and the movie can be played back as usual.
Further, the display order of the two-screen playback can be arranged on the left side of the data with a smaller DCF (Design rule for Camera File system) number or arranged in the system area toward the display.
In addition, in order to make it possible for two-screen playback to compare a good player such as a professional golfer vs. a user (which can only be erased with a specific file), the professional golfer's movie data is placed in the system area and compared with a professional golfer on a two-screen basis. Can do. In this case, the professional golfer's movie can be set to be used any number of times.

In addition, the data in the system area can be displayed in the PLAY steady state as usual data (even when the built-in memory or SD memory card is used). However, it can be made non-compliant except for slide show and enlarged reproduction.
In addition, it is possible to set so that audio reproduction during two-screen reproduction is not possible. In addition, after turning on the power of the playback control device 1, it is possible to prepare an environment in which a professional movie can be downloaded from the WEB to the two-screen list sample and two-screen comparison can be performed. (For example, “CIMG0001.MOV” can be set as the professional file name and “2012/1/1” can be set as the date).
In addition, the professional golfer's movie can be changed by the user to change the selection of two screens or the start point. If the SD memory card is write-protected, an error message is displayed when the menu setting “2 screen playback” is selected.
Also, the combination data for two-screen playback is stored in an SD memory card (for example, “EXILIM” can be set as the folder name and “dmp.bin” can be set as the file name).

As described above, the playback control device 1 according to the present embodiment that executes playback control in units of a plurality of moving image data to be simultaneously played as a moving image set includes the simultaneous playback information storage unit 62 and A simultaneous reproduction control unit 45.

Therefore, when a moving image set in which simultaneous playback information is registered in advance is generated, simultaneous playback can be easily performed based on the frame position included in the playback condition.

Further, the playback condition of the playback control device 1 of the present embodiment includes the frame position (start point) of each moving image data from which playback is started.
Thereby, since a moving image can be reproduced from the start point of each moving image data constituting the moving image set, each moving image can be easily reproduced simultaneously under a desired reproduction condition.

In addition, when the first moving image data is included in a plurality of moving image sets, the reproduction control device 1 of the present embodiment has different reproduction conditions depending on the difference in the moving image data of the other party combined with the first moving image data. Accordingly, the frame position for matching the reproduction timing of the first moving image data is designated to be different.
As a result, the playback condition is specified so that the frame position for matching the playback timing is a different frame position according to the difference in the moving image data of the other party combined with the first moving image data. Therefore, when a moving image set combined with the first moving image data is generated in advance, the first moving image data and the moving image data of the other party are respectively set from desired frame positions without specifying the reproduction conditions again. Simultaneous playback is possible.

In addition, the reproduction control device 1 of the present embodiment is configured such that the first moving image data in which a golf swing serving as a model is photographed is between a plurality of moving image data in which a plurality of golf swings to be compared are photographed. When a plurality of video sets are configured, the playback condition is a frame position that should match the playback timing of the first video data and corresponds to one of a plurality of checkpoints specific to the golf swing, It is specified to be different according to the difference in checkpoints to be compared in the moving image data on the side.
Thereby, it is specified that the frame position corresponding to any of the plurality of check points unique to the golf swing of the first moving image data is made different according to the difference of the check points to be compared in the opponent moving image data. The For this reason, each golf swing can be easily reproduced by simultaneously reproducing from a desired frame position, such as a frame position for matching the impact reproduction timing and a frame position for matching the top reproduction timing. .

In addition, the reproduction control device 1 of the present embodiment further includes a data selection unit 71.
The data selection unit 71 causes the user to select a plurality of moving image data to be included in the moving image set in a state where a plurality of moving image data is displayed as a list on a predetermined display device. Then, after one moving image data is selected, the data selection unit 71 determines whether or not the remaining moving image data is inappropriate for simultaneous reproduction with the selected moving image data, and the moving image data determined to be inappropriate A plurality of moving image data is displayed in a list on a predetermined display device in a state in which selection of is prohibited.
Thus, the user can select only moving image data suitable for simultaneous reproduction only by selecting moving image data that is not prohibited. Therefore, the user can perform simultaneous reproduction based on moving image data that is easy to compare without particular awareness.

In addition, the reproduction condition of the reproduction control device 1 of the present embodiment includes an arrangement condition in a case where a plurality of moving image data to be reproduced simultaneously are arranged on the same screen.
Accordingly, it is possible to specify, as playback conditions, arrangement conditions such as vertical placement and horizontal placement of each moving image, relative arrangement positions of each moving image, display size of each moving image, and the like. Therefore, for example, when moving image data with the same arrangement condition is selected, it is possible to compare and reproduce the moving images with the desired arrangement condition without specifying the reproduction condition again.

In addition, the playback control device 1 of this embodiment further includes a moving image storage unit 61.
The moving image set of the present embodiment indicates moving image data stored in the moving image storage unit 61. Then, the simultaneous playback control unit 45 reads a plurality of moving image data indicated by the specified moving image set from the moving image storage unit 61 and simultaneously reproduces them.
Thus, by preparing in advance the moving image data that is the target of the moving image set, it is possible to easily reproduce a plurality of moving image data.

  The reproduction control apparatus 1 according to the present embodiment further includes an imaging unit 16 and a main control unit 41. The imaging unit 16 captures moving image data.
