[0036] The storage unit 221 stores parameters, data, control programs, etc. for realizing predetermined functions. The storage unit 221 is configured, for example, with an HDD or SSD. For example, the storage unit 221 stores the above-mentioned programs and various image data, etc.

[0037] The temporary storage unit 222 is configured with a RAM such as a DRAM or an SRAM, and temporarily stores (i.e., holds) data. For example, the temporary storage unit 222 holds image data that is in the middle of being edited. The temporary storage unit 222 may also function as a work area for the control unit 210, and may be configured as a storage area in the internal memory of the control unit 210.

[0038] The operation unit 230 is a general term for operation members operated by the user. The operation unit 230 is, for example, a touch panel superimposed on the display unit 240 for inputting various touch operations, and is an example of an input unit of the information support terminal 200. The input unit may be a connection software unit that communicates with various external input devices and receives operation signals. The operation unit 230 may be physical buttons or switches provided on the information support terminal 200, or may be a keyboard, mouse, touchpad, or the like. The operation unit 230 may be various GUIs such as virtual buttons, icons, cursors, software keyboards, and objects displayed on the display unit 240.

[0039] The display unit 240 is configured with, for example, a liquid crystal display or an organic EL display. The display unit 240 may display various types of information, such as various GUIs for operating the operation unit 230 and information input from the operation unit 230.

[0040] The communication unit 250 is a module (circuit) that connects to an external device in accordance with a predetermined communication standard for wired or wireless communication. The predetermined communication standard includes, for example, USB, HDMI, IEEE802.11, Wi-Fi, Bluetooth, etc. The communication unit 250 may connect the information support terminal 200 to a communication network such as the Internet.

[0043] The above-described configuration of information support terminal 200 is an example, and the configuration of information support terminal 200 is not limited to this. For example, various display devices such as a projector and a head-mounted display may be used for display unit 240 of information support terminal 200. Furthermore, when an external display device is used, display unit 240 of information support terminal 200 may be an output interface circuit for a video signal conforming to, for example, the HDMI standard.

[0044] 2.Operation The operation of the system 10 configured as above will be described below.

[0045] In the present system 10, the information support terminal 200 has various functions for sequentially providing information support to the user in the workflow of video production. An example of a screen display for selecting various functions of the information support terminal 200 is shown in FIG.

[0046] The display unit 240 of the information support terminal 200 displays a scenario creation button 11, a shooting button 12, and an export button 13 on the function selection screen illustrated in Fig. 4. Hereinafter, the longitudinal direction of the screen of the display unit 240 is referred to as the X direction, and the width direction is referred to as the Y direction.

[0047] The scenario creation button 11 is a virtual button that accepts user operation to execute a function (i.e., a scenario creation function) that provides information support for the process in which the user creates a scenario before shooting a video in the system 10. The information support terminal 200 of the system 10 manages various information for each cut, such as a shooting section that divides the scenario created in this way. A cut constitutes, for example, a section in multiple video shoots for a scenario.

[0048] The shooting button 12 is a virtual button for executing a function (i.e., a cut shooting function) that supports video shooting of each cut in a scenario created by, for example, the scenario creation function. The number of times a video is shot for one cut is not limited to one take, and multiple takes may be used. In this embodiment, the information support terminal 200 controls video shooting by the digital camera 100 in the cut shooting function and manages the shooting results for each cut.

[0049] The export button 13 is a virtual button for executing a function (i.e., an export function) that performs preprocessing for external output on the management results of video shooting using the cut shooting function and outputs the result. The preprocessing using the export function provides information support that makes it easier to edit multiple video shoot results according to a scenario on the video editing PC 300, for example.

[0050] The information support terminal 200 of this system 10 can provide consistent information support from scenario creation to pre-processing of video editing, for example, by the user sequentially using each function of the scenario creation button 11, shooting button 12, and export button 13.

[0051] In the present system 10, the function selection screen of the information support terminal 200 may further include a delete button for deleting various data in the information support described above. For example, in response to a user operation of the delete button, the information support terminal 200 may collectively delete video files of the same scenario.

[0052] 2.1. About the Scenario Creation Function The scenario creation function of the information support terminal 200 of the present system 10 will be described with reference to FIGS. 5A to 6. FIG.

[0053] Fig. 5A shows an example of a scenario input screen displayed on information support terminal 200. When a user operation, such as tapping scenario creation button 11 on the function selection screen of Fig. 4, is input from operation unit 230, control unit 210 of information support terminal 200 causes display unit 240 to display the scenario input screen as shown in Fig. 5A.

[0054] The scenario input screen is a screen that allows the user to input a scenario into the information support terminal 200 in the scenario creation function of the present system 10. As shown in FIG. 5A, for example, the scenario input screen includes a storyboard input field 20 for each cut, a cut edit button 14, and a back button 15. The control unit 210 of the information support terminal 200 accepts various user operations related to the scenario input screen displayed on the display unit 240 at the operation unit 230.

[0055] In the information support terminal 200, the storyboard input field 20 accepts user input of information indicating a storyboard, such as an outline of the scenario concept, for each scene that makes up the scenario. The storyboard input field 20 for each scene includes, for example, a composition field 21, a script field 22, a shooting time field 23, a shooting location field 24, and a memo field 25, as shown in FIG. 5A .

[0056] The composition field 21 accepts input of composition information indicating the composition of the moving image shooting of the cut, etc. An example of a storyboard editing screen for editing the composition of each cut is shown in FIG.

[0057] The storyboard editing screen illustrated in Fig. 5B includes an editing method selection field 26, an object selection field 27, an object selection field 28, and a back button 15. The storyboard editing screen in Fig. 5B is displayed, for example, by tapping the composition field 21 of the cut to be edited on the scenario input screen in Fig. 5A, or by selecting the corresponding menu and then selecting the editing method "object" in the editing method selection field 26.

[0058] The "object" editing method is a method for editing the composition information of the storyboard for each cut by, for example, selecting an object representing the subject expected in each cut from the object selection column 27 and arranging it in the desired composition in the object selection column 28.

[0059] The object selection field 27 includes options for objects of each type. The object types may be categories such as "people," "vehicles," or "animals," or may be subcategories subdivided into each category.

[0060] The object selection field 28 manages the spatial coordinates (U, V, Z) at which an object is placed. The spatial coordinates (U, V, Z) in the object selection field 28 include, for example, two-dimensional coordinates (U, V) corresponding to the angle of view range of the video and the depth coordinate Z of the subject. The depth coordinate Z is managed according to, for example, the overlap between placed objects or the size of the object.

[0061] 5B, one object of the type "person" and two objects of the type "vehicle" are arranged at the foreground and the background in the depth direction (Z) in the object selection field 28. In this method, the storyboard composition information for each cut is object information including, for example, the type and number of such objects and their positional relationships such as spatial coordinates (U, V, Z).

[0062] In the present system 10, the composition information is not limited to the above examples, and may be, for example, image information. Furthermore, the method of editing the composition information is not limited to the above examples, and may be, for example, "template" which allows a pre-prepared composition template to be selected, "background" which allows a background to be selected, or "handwriting" which allows handwritten input, as shown in the selection field 26 in FIG. 5B. Image information may be input by drawing through a user operation, or by specifying image data. Each of these various pieces of composition information or various pieces of storyboard information is an example of subject information in this embodiment.

[0063] Returning to FIG. 5A, the script field 22 accepts text input such as a script divided into portions for the scenes in the scenario.

[0064] The shooting time field 23 accepts a numerical input indicating the estimated length of time it will take to shoot the video of the cut. The shooting location field 24 accepts an input of information indicating the location where the video of the cut will be shot. The shooting location may be input as text, or data search may be used as appropriate. The memo field 25 accepts input of various information desired by the user regarding the shooting of the video of the cut, such as the shooting equipment, for example, as text.

[0065] 5A, the display unit 240 displays storyboard input fields 20 for two cuts. The control unit 210 acquires storyboard information for each cut in accordance with user input into the various fields 21 to 25 in the storyboard input field 20 for each cut in the scenario. On the scenario input screen of the information support terminal 200, the storyboard input field 20 for the cut displayed on the display unit 240 can be changed, for example, in response to a swipe operation for scrolling in the X direction in which the storyboard input fields 20 for each cut are arranged.

[0066] The cut edit button 14 switches on / off a state in which various user operations can be input, such as adding, deleting, and changing the order of cuts to be included in the scenario. For example, by performing a touch operation while the cut edit button 14 is in the on state, the user can arrange the storyboard input fields 20 for the desired number of cuts in chronological order in the scenario.

[0067] The back button 15 accepts a user operation to go back one screen in the screen transition of the information support terminal 200. For example, the control unit 210 transitions the display unit 240 to the function selection screen (FIG. 4) in response to a user operation of the back button 15 on the scenario input screen (FIG. 5A). The control unit 210 of this embodiment generates cut data including storyboard information for each cut as an output of such a scenario creation function and stores the cut data in the storage unit 220. An example of such cut data at the end of the scenario creation function is shown in FIG. 6.

[0068] 6, the cut data D1 is managed by associating, for each "cut number," a "script," a "composition," a "shooting time," a "shooting location," a "shooting completion flag," and a "video management data list." The cut data D1 is an example of management information in this embodiment.

[0069] The control unit 210 of the information support terminal 200 assigns cut numbers indicating identification information of the cuts in the cut allocation data D1 in ascending order in the storyboard input field 20 for each cut arranged on the scenario input screen, for example. Furthermore, if the order of the cuts is changed, the control unit 210 reassigns the cut numbers according to the changed order. For each cut, the control unit 210 records the information entered in the script field 22, composition field 21, shooting time field 23, shooting location field 24, and memo field 25 of the storyboard input field 20 in the "script," "composition," "shooting time," and "shooting location" fields of the cut allocation data D1, respectively.

[0070] In the cut division data D1, the "shooting completion flag" manages whether the shot in question has been shot or not by setting it to ON / OFF. When the scenario creation function is terminated, the shooting completion flag for all shots is set to OFF as the initial setting.

[0071] The "video management data list" is a list for storing management data for the video that is shot in association with the cut. Such video management data may be metadata for the video. When the scenario creation function is terminated, the video management data list is initially set to null.

[0072] As described above, the scenario creation function of the information support terminal 200 of this system 10 generates cut-by-cut data D1 from user input on the scenario input screen, thereby providing information support for the process of creating a scenario for the user's desired video work cut by cut.

[0073] The scenario creation function of information support terminal 200 is not particularly limited to the above. For example, information support terminal 200 may accept a user instruction to output storyboard information of a scenario entered on a scenario input screen using a data format (e.g., PDF format) that can be shared with another device, and output the data.

[0074] 2.2.About the Cut Shooting Function The operation of the snapshot photography function in the information support terminal 200 of the system 10 will be outlined with reference to FIG.

[0075] 7 shows an example of a cut selection screen displayed on the information support terminal 200. The cut selection screen is a screen for the cut shooting function of the present system 10 to select a desired cut from among cuts provided by, for example, the scenario creation function. The cut selection screen is an example of a selection screen on the information support terminal 200 of this embodiment.

[0076] 7, the cut selection screen includes a cut list 30, a storyboard display field 31, a filter button 32, an add cut button 33, a recording mode button 34, a playback mode button 35, and a back button 15. The cut list 30 is a list that lists various cuts as options that the user can select. The storyboard display field 31 is a display field that displays storyboard information about the selected cut. The cut selection screen will be described in detail later.

[0077] In the cut shooting function of the present system 10, the information support terminal 200 provides information support that makes it easy for the user to comprehensively proceed with video shooting of each cut while checking various cuts, for example, by using a cut selection screen shown in Fig. 7. The user may shoot videos in an order different from the order of the cuts in the scenario, or may shoot multiple takes for one cut of video.

[0078] Therefore, the information support terminal 200 of the present system 10 accepts the user's evaluation of the selected cut as the video of each take is shot, manages whether or not the shooting of the cut has been completed, and visualizes to the user the progress of video shooting for each cut in the cut list 30. The operation of the present system 10 will be described in detail below.

[0079] 2.2.1. Overall operation of the snapshot function The overall operation of the cut photography function in the system 10 will be described with reference to FIGS.

[0080] Fig. 8 is a flowchart illustrating the operation of the shot shooting function in the system 10. Each process shown in the flowchart in Fig. 8 is executed, for example, by the control unit 210 of the information support terminal 200. The process of this flow starts, for example, when the shooting button 12 on the function selection screen (Fig. 4) is operated in a state where shot data D1 generated by the scenario creation function has been stored in the storage unit 220 and a communication connection with the digital camera 100 has been established in the communication unit 250.

[0081] First, the control unit 210 of the information support terminal 200 generates a cut list 30 to be displayed on the cut selection screen (FIG. 7) based on the cut layout data D1 (S1). The cut list generation process (S1) is repeatedly executed in the system 10, for example, during execution of the cut shooting function, in accordance with the progress of video shooting and various user operations, and the cut list 30 is updated successively. The process of step S1 will be described in detail later.

[0082] Next, the control unit 210 causes the display unit 240 to display a cut selection screen, for example as shown in FIG. 7, based on the generated cut list 30 and the cut layout data D1 (S2).

[0083] 7, the cut list 30 on the cut selection screen includes a plurality of cut icons 3. Each cut icon 3 indicates an individual cut as an option. The cut icon 3 being selected is set to cut number "1" in the initial state, for example.

[0084] For example, the control unit 210 controls the display unit 240 to highlight the cut icon 3 indicating the selected cut (S2). The selected cut icon 3 is highlighted, for example, by displaying it in a larger size than the other cut icons 3 and by surrounding it with a frame in a highlighting color. Furthermore, the control unit 210 references the cut allocation data D1 and causes the storyboard display column 31 to display storyboard information about the cut indicated by the selected cut icon 3 (S2).

[0085] In the example of Fig. 7, the cuts with cut numbers "1" and "4" are in an incomplete state, while the cuts with cut numbers "2" and "3" are in a completed state. In the cut list 30 of this embodiment, the cut icon 3 has a display attribute that distinguishes between a completed state and an incomplete state. Such a display attribute is set, for example, so that the display mode of the completed state highlights the display mode of the incomplete state.

[0086] 7, the control unit 210 accepts various user operations on the operation unit 230, such as a touch panel, when the display unit 240 displays a cut selection screen (S3). The user operations that are the subject of step S3 include (I) a cut selection operation, (II) an operation to switch to a recording mode, (III) an operation to switch to a playback mode, (IV) a filtering operation, (V) an operation to add a cut, and (VI) an operation to end the operation.

[0087] The cut selection operation ((I) in S3) is a user operation for changing the selected cut, and is, for example, an operation of tapping a cut icon 3 other than the selected cut icon 3 in the cut list 30 displayed on the cut selection screen. The cut selection operation is not limited to this, and for example, a swipe operation in the storyboard display field 31 may be input as a cut selection operation for changing from the selected cut to an adjacent cut.

[0088] When a cut selection operation is input ((I) of S3), the control unit 210 changes the selected cut icon 3 in accordance with the input cut selection operation (S4), and performs the processes from step S2 onwards again. As a result, the selected cut icon 3 is changed on the cut selection screen, and the storyboard display column 31 for the newly selected cut is displayed (S2).

[0089] The transition operation to the recording mode ((II) of S3) is a user operation for transitioning to the recording mode, which is an operating mode for shooting video of the selected cut, and is, for example, a tap operation on the recording mode button 34. In addition to or instead of this, the transition operation may be a swipe operation in a predetermined direction of the ±X directions on the cut selection screen. Also, the recording mode button 34 may be omitted.

[0090] When an operation to switch to recording mode is input ((II) of S3), the control unit 210 executes various processes for recording one take of a moving image in association with the selected cut in recording mode (S5). An example of the display in step S5 is shown in FIG.

[0091] 9 shows an example of a rating screen displayed on information support terminal 200. The rating screen is a screen for prompting the user to rate the video of the taken take. The rating screen is an example of an evaluation screen on information support terminal 200 of this embodiment.

[0092] 9, the rating screen includes an information display field 40 about the filmed video, and rating options including an OK button 41, a KEEP button 42, and an NG button 43. The information display field 40 displays information about the filmed take of the video, including, for example, a thumbnail image of the take, the cut number associated with the take, and the number of takes.

[0093] The OK button 41 indicates, for example, an "OK" rating when the user has decided that the take should be used in the corresponding cut. The KEEP button 42 indicates, for example, a "KEEP" rating when the user is unsure whether to use the take. The NG button 43 indicates, for example, an "NG (No Good)" rating when the user has clearly decided not to use the take. In this embodiment, the rating "NG" is an example of a first rating, and the ratings "OK" and "KEEP" are each examples of a second rating.

[0094] In the recording mode process (S5) of this embodiment, each time one take of video is shot, a rating screen such as that shown in Fig. 9 is displayed to obtain evaluation information indicating the user's evaluation of that take. Based on the rating results of this recording mode process (S5), the control unit 210 performs the cut list generation process (S1) again as shown in Fig. 8 to update the cut list 30. The process of step S5 will be described in detail later.

[0095] The operation to transition to playback mode ((III) of S3) is a user operation for transitioning to playback mode, which is an operating mode for playing back and displaying the video shot for the selected cut, and is, for example, an operation of the playback mode button 35. In addition to or instead of this, the operation to transition to playback mode may be a swipe operation in the ±X direction of the cut selection screen, opposite to the operation to transition to recording mode. Also, the playback mode button 35 may be omitted.

[0096] When an operation to transition to playback mode is input ((III) of S3), the control unit 210 executes a process to play back various takes of video related to the cut currently selected in playback mode (S6). In the playback mode process (S6) in this embodiment, re-rating can be performed to change the evaluation of the video of each take. Based on the re-rating results of the playback mode process (S6), the control unit 210 performs the cut list generation process (S1) again to update the cut list 30. Details of the process of step S6 will be described later.

[0097] The filtering operation (S3(IV)) is a user operation for narrowing down the cuts to be displayed in the cut list 30, for example, by operating the filter button 32. When the filtering operation is input (S3(IV)), the control unit 210 acquires the conditions for filtering the cuts to be displayed in accordance with the user's selection (S7).

[0098] The information support terminal 200 of this embodiment uses the shooting locations in the storyboard information of each cut as filtering conditions for the cut list 30. The control unit 210 performs the cut list generation process (S1) again based on the shooting locations acquired as filtering conditions. In this way, the cut list 30 is updated so as to limit the cut icons 3 to those corresponding to the shooting locations of the filtering conditions (details will be described later).

[0099] The cut addition operation (S3(V)) is a user operation for adding a new cut to the cut list 30 in addition to the existing cuts, for example, the operation of the cut addition button 33. When the cut addition operation is input (S3(V)), the control unit 210 sets various information about the added cut (S8) and performs the cut list generation process (S1) again (details will be described later).

[0100] The end operation (S3(VI)) is a user operation for ending the shot shooting function, such as operating the back button 15 on the shot selection screen (FIG. 7). When the end operation is input (S3(VI)), the control unit 210 transitions the display unit 240 from the shot selection screen to the function selection screen (FIG. 4), for example, and ends the processing shown in this flow.

[0101] According to the above process, the user of the system 10 can check various cuts (S4) on the cut selection screen (FIG. 7) in the cut shooting function of the information support terminal 200, and can shoot a video of the desired cut (S5) and play back and display it (S6). In this way, the user can easily manage the video shooting of multiple cuts in a scenario.

[0102] In the cut selection screen of this embodiment, each cut icon 3 is displayed with a distinguishable indication of whether or not shooting has been completed, thereby preventing the user from forgetting to shoot a cut. The distinguishable indication of whether or not shooting of each cut has been completed is performed in a manner that reflects the user's evaluation of each take of video, making it easy to ensure video quality that meets the user's intentions. Such ratings are performed for each take (S5), and further re-rating can be performed in playback mode (S6). This makes it easy to achieve quality control of video shooting that meets the user's intentions.

[0103] Furthermore, the cut selection screen (FIG. 7) of this embodiment is not limited to updating the cut list 30 in accordance with the rating / re-rating of cuts as described above (S5, S6, S1), but can also be updated to filter the display targets or add cuts (S7, S8, S1). This allows the user to efficiently use the desired cuts on the cut selection screen, for example, when shooting a video, making it easier to use the cut shooting function of this system 10.

[0104] In the shot shooting function of this embodiment, the communication connection with the digital camera 100 may be managed, and for example, a button for managing the communication connection may be provided on the shot selection screen. When the communication connection with the digital camera 100 is not established, the control unit 210 may disable the operation to switch to the recording mode ((II) in S3).

[0105] 2.2.2.Cut list generation process The cut list generation process in step S1 of FIG. 8 will be described in detail with reference to FIGS.

[0106] Fig. 10 is a flowchart illustrating the cut list generation process (S1) in the present system 10. The process shown in the flow of Fig. 10 is started, for example, in response to the operation of the capture button 12 on the function selection screen (Fig. 4). Alternatively, the process of this flow is started after steps S5 to S8 are executed in response to a predetermined user operation ((II) to (V) of S3 in Fig. 8) on the cut selection screen (Fig. 7).

[0107] First, the control unit 210 of the information support terminal 200 selects one cut from all the cuts included in the cut allocation data D1 (FIG. 6) to check whether it should be included in the cut list 30 (S10). The selection in step S10 is performed, for example, in ascending order of the cut numbers in the cut allocation data D1.

[0108] Next, the control unit 210 determines whether or not the shooting location of the shot to be checked satisfies the filtering conditions, for example, based on the shooting location of the shot to be checked in the shot allocation data D1 (S11). Such filtering will be described with reference to FIG.

[0109] Fig. 11 shows an example of the display of the selection dialog 32a in step S7 of Fig. 8. For example, when the user taps the filter button 32 on the cut selection screen (Fig. 7) ((IV) of S3), the display unit 240 displays the selection dialog 32a in step S7. The selection dialog 32a includes options for filtering conditions such as "All Locations," "Shooting Location 1," "Shooting Location 2," etc.

[0110] For example, the filtering condition is initially set to "all locations" (see filter button 32 in FIG. 7), and in this case the determination in step S11 is "YES." Also, when a specific shooting location is selected as a filtering condition in the user's filtering operation ((IV) of S3 in FIG. 8) (S7), the control unit 210 determines whether the shooting location of the cut to be checked matches the specific shooting location (S11).

[0111] 8, the control unit 210 displays a selection dialog 32a (FIG. 11) based on various shooting locations included in the shot layout data D1, and accepts a user operation to select one of the options in the selection dialog 32a. For example, when the user taps on one of the options in the selection dialog 32a, the control unit 210 acquires the shooting location of that option as a filtering condition (S7), and makes a determination in step S11 of the shot list generation process (S1) based on the filtering condition.

[0112] 10, if the shooting location to be checked does not meet the filtering conditions (NO in S11), the control unit 210 proceeds to step S16 without performing steps S12 to S15, such as generating a cut icon 3. In this way, cuts with shooting locations that differ from the filtering conditions are excluded from the cut list 30 to be displayed.

[0113] If the shooting location to be checked meets the filtering conditions (YES in S11), the cut is included in the display targets of the cut list 30. In this case, the control unit 210 generates, for example, a cut icon 3 corresponding to the cut (S12).

[0114] Next, the control unit 210 determines whether the shooting completion flag of the cut that generated the cut icon 3 is ON, for example, based on the cut division data D1 (S13). The shooting completion flag is turned ON if, for example, the videos associated with the cut to be checked include videos rated "OK" or "KEEP," and is turned OFF otherwise. The determination in step S13 may be made by referring to the ratings of each video associated with the cut to be checked, instead of using the shooting completion flag.

[0115] If the shooting completion flag of the cut is ON (YES in S13), the control unit 210 sets the display attribute of the shooting completion state to the corresponding cut icon 3 (S14).

[0116] On the other hand, if the shooting completion flag of the cut is OFF rather than ON (NO in S13), the control unit 210 sets the display attribute of the corresponding cut icon 3 to indicate an incomplete shooting state (S15).

[0117] The control unit 210 determines whether or not all of the cuts to which cut numbers have been assigned have been checked, for example, based on the cut allocation data D1 (S16). The determination in step S16 is made within the range of cuts (hereinafter referred to as "normal cuts") that have been included in the cut allocation data D1 since the scenario was created, separate from the additional cuts.

[0118] If all normal cuts have not been checked (NO in S16), the control unit 210 repeats the process from step S11 onwards for the unchecked normal cuts. In this way, all normal cuts are checked in sequence for display in the cut list 30 (YES in S16).

[0119] When all normal cuts have been checked (YES in S16), the control unit 210 determines whether there are any additional cuts (S17). The additional cuts are set in step S8 of Fig. 8 so that they are assigned additional cut numbers, which are identification information different from the cut numbers in the cut division data D1 (see Fig. 12).

[0120] If there are no additional cuts (NO in S17), the control unit 210 does not particularly perform the process of step S18, and generates a cut list 30 based on the check results of the normal cuts (S11 to S16) (S19). For example, in the cut list 30, the cut icons 3 to be displayed are arranged in ascending order of cut numbers.

[0121] On the other hand, if there are additional cuts (YES in S17), the control unit 210 performs various processes for checking the additional cuts to be displayed in the cut list 30, in the same way as for normal cuts (S18). The process of step S18 is performed in the same way as the processes of steps S11 to S16, except that the range of the additional cuts, instead of the normal cuts, is the check target. In this case, the control unit 210 generates the cut list 30 based on the check results of the normal cuts and the additional cuts (S11 to S16, S18) (S19).

[0122] When the cut list 30 is generated in this way (S19), the control unit 210 ends the processing of, for example, step S1 in FIG. 8, and proceeds to step S2.

[0123] According to the cut list generation process (S1) described above, the information support terminal 200 of the system 10 generates a cut list 30 that lists the cuts included in the scenario based on the cut allocation data D1, with an indication of whether or not shooting has been completed (S14, S15). When the evaluation for each take of each cut changes (S5, S6 in FIG. 8), the indication of the cut list 30 is dynamically updated in accordance with the changed evaluation. This makes it easy for the user to check the progress of shooting a video with multiple cuts.

[0124] Furthermore, in the present system 10, the shot list 30 can be narrowed down using the shooting location as a filtering condition (see S7 in FIG. 8 and S11 in FIG. 10). This allows the user to use the shot selection screen by selecting, for example, the shooting location of the location as a filtering condition, narrowing down the shots to be shot on location. In this way, the present system 10 makes it easier for the user to prevent forgetting to take shots on location.

[0125] Furthermore, in the present system 10, the cut list 30 can also be updated to include additional cuts (see S8 in FIG. 8 and S17 to S18 in FIG. 10). An example of the cut list 30 when additional cuts are included is shown in FIG.

[0126] For example, when the user performs a cut addition operation ((V) of S3 in FIG. 8), the control unit 210 sets the added cut (S8), and then proceeds to YES in step S17 in the cut list generation process (S1), and checks the added cut (S18). In this way, for example, as shown in FIG. 12, the cut list 30 is updated to include a cut icon 3a for the added cut.

[0127] With the added cut feature of the present system 10, the user can instantly add cuts on location, such as at a shooting location, without having to re-edit the scenario. The cut icon 3a for the added cut is placed at the end of the cut list 30, for example, in step S1 after step S8, as shown in Fig. 12. If there are multiple added cuts, they are placed in ascending order of the added cut number, for example.

[0128] Also, in step S8 of FIG. 8, the control unit 210 automatically sets, for example, the shooting location in the storyboard information of the added cut in accordance with the filtering conditions. Alternatively, the shooting location of the added cut may be set by user input. By setting the shooting location of the added cut in this way, the added cut can also be subject to filtering (S7) in the same way as normal cuts. For example, the storyboard information of the added cut is set to null values ​​other than the shooting location. A predetermined image indicating that it is an added cut may be used as the composition of the storyboard information. Also, the added cut may be deleteable by a predetermined user operation, and for example, the predetermined user operation may be a long press on the cut icon 3a of the added cut.

[0129] 2.2.3. Recording Mode The details of the recording mode process in step S5 in FIG. 8 will be described with reference to FIGS.

[0130] Fig. 13 is a flowchart illustrating the recording mode process (S5) in the present system 10. The process shown in the flow of Fig. 13 starts when, for example, an operation to switch to the recording mode is input on the cut selection screen (Fig. 7) (S3 (II)).

[0131] First, the control unit 210 of the information support terminal 200 shifts to a recording mode and causes the display unit 240 to transition to a screen for waiting for video recording (S30). An example of the display on the information support terminal 200 in step S30 is shown in FIG. 14(A).

[0132] 14A, the recording standby screen in step S30 includes a timer button 44, a live view image 45, and a recording button 46. The timer button 44 accepts a user operation to set a timer period for timing the start of shooting, for example. The recording button 46 accepts a user operation to start shooting and recording a video.

[0133] In the present system 10, when the control unit 210 of the information support terminal 200 transitions to, for example, a recording mode, it requests the digital camera 100 to transmit a live view image 45 via the communication unit 250 (S30). For example, in the recording mode, the control unit 210 sequentially receives image data of the live view image 45 from the digital camera 100 via the communication unit 250 and displays the live view image 45. Furthermore, the control unit 210 may also receive, as appropriate, audio data of the sound picked up by the microphone 160 from the digital camera 100.

[0134] The control unit 210 sets a timer period in response to, for example, a user operation of the timer button 44 (S31). An example of the display on the information support terminal 200 in step S31 is shown in Fig. 14(B). The timer period may be set for each take or uniformly for each cut.

[0135] 14B illustrates an example of a timer selection field 44a that is displayed in response to operation of the timer button 44 on the shooting standby screen of FIG. 14A. FIG. 14B shows an example in which the timer period is set to "5 seconds" in the timer selection field 44a. The timer selection field 44a includes options indicating the numerical value of the timer period, such as "OFF," which corresponds to a timer period of 0 seconds, and "5 seconds." In step S31, when the control unit 210 receives a user operation on the timer selection field 44a via the operation unit 230, the control unit 210 sets the timer period in accordance with the user operation and returns the display unit 240 from FIG. 14(B) to FIG. 14(A).

[0136] In response to a user operation of the record button 46, the control unit 210 performs various controls to start shooting and recording one take of a moving image associated with the selected cut (S32). For example, in step S32, the control unit 210 instructs the digital camera 100 to start shooting and recording the moving image via the communication unit 250. Examples of the display on the information support terminal 200 in step S32 are shown in FIGS. 14(C) and 14(D).

[0137] FIG. 14(C) illustrates an example of a shooting screen when the recording button 46 is operated when a timer period is set as in the example of FIG. 14(B). FIG. 14(D) illustrates an example of a shooting screen after the timer period from FIG. 14(C). The control unit 210 counts down the elapsed time from the time the recording button 46 is operated (S32) by the set timer period, and displays it superimposed on, for example, a live view image. In this example, video recording is performed including this timer period. Furthermore, if the timer period is set to "OFF," in step S32, the control unit 210 does not particularly display the countdown as in FIG. 14(C), and transitions the display unit 240 to, for example, the shooting screen as in FIG. 14(A) to FIG. 14(D).

[0138] 14(C) and (D), the shooting screen in step S32 includes a live view image 45, a time display field 47, a recording stop button 46a, and a marking button 48. The live view image 45 on the shooting screen is highlighted, for example, with a frame or other display to indicate that recording is in progress. The time display field 47 displays, for example, the shooting time of a selected cut in the cut data D1 and the elapsed time since the start of shooting of the video of that take, for comparison.

[0139] In step S32, the control unit 210 controls the display unit 240 to switch the display from the shooting standby screen (FIG. 14(A)) to the shooting screen (FIGS. 14(C) and (D)). The control unit 135 of the digital camera 100 starts shooting video in accordance with an instruction from the information support terminal 200 received via the communication module 155, for example.

[0140] At this time, the control unit 135 repeats the imaging operation of the image sensor 115 and records the video data of the imaging results onto the memory card 142, for example, via the card slot 140. The video data includes, for example, audio data collected by the microphone 160. The control unit 135 may start collecting audio in synchronization with the video imaging in the digital camera 100 in response to such an imaging instruction. The control unit 135 of the digital camera 100 determines a file name for the video data according to, for example, the shooting order, and transmits the determined video file name to the information support terminal 200 via the communication module 155.

[0141] For example, on the shooting screen of Fig. 14(D), a recording stop button 46a is operated by the user to stop shooting and recording a moving image. A marking button 48 is operated by the user to mark a desired timing during shooting of a moving image. The user can use the marking button 48 at a timing they want to refer to, for example, when editing the moving image in post-processing.

[0142] Thereafter, the control unit 210 performs various controls to stop the video recording in response to the user's operation of the recording stop button 46a (S33). For example, in step S33, the control unit 210 instructs the digital camera 100 to stop the video recording via the communication unit 250. The control unit 135 of the digital camera 100 ends the video recording in accordance with the instruction from the information support terminal 200.

[0143] Furthermore, the control unit 210 causes the display unit 240 to display a rating screen, as shown in FIG. 9, for example, in order to prompt the user to rate the video of the take shot as described above (S34).

[0144] The control unit 210 receives user operations on various buttons 41 to 43 on a rating screen such as that shown in Fig. 9, and acquires the user's evaluation as a rating result for the video of the taken take (S35). In this embodiment, each time a video of one take is shot, the user can arbitrarily select a desired evaluation from the three types of evaluations "OK," "KEEP," and "NG" for the shot video, without interfering with the evaluations of other videos of the taken.

[0145] The control unit 210 determines, for example, whether the user's evaluation is "NG" or not based on the acquired user's evaluation (S36). For example, if the user's evaluation is "OK" or "KEEP," the determination in step S36 is "NO."

[0146] If the acquired user evaluation is not "NG" (NO in S36), the control unit 210 sets the shooting completion flag of the cut associated with the take in the cut division data D1 (i.e., the selected cut) to "ON" (S37). For example, if the number of takes in the video is "1," or if the number of takes is "2" or more and the evaluation of the video of the existing takes is "NG," the shooting completion flag is switched from "OFF" to "ON" by executing step S37.

[0147] On the other hand, if the acquired user evaluation is "NG" (YES in S36), the control unit 210 proceeds to step S38 without particularly updating the setting of the shooting completion flag. As a result, if the shooting completion flag for the corresponding cut when the video with the evaluation "NG" was shot is OFF, for example, the OFF state is maintained. Also, if the shooting completion flag is ON because a video of a take shot in the past has "KEEP" or "OK", for example, the ON state is maintained.

[0148] The control unit 210 generates management data for the moving image of the takes shot as described above, and records it as cut data D1 in the storage unit 220, for example (S38). An example of such moving image management data D2 is shown in FIG.

[0149] 15, the video management data D2 includes a "video file name," "rating information," a "timer period," "marker information," and a "thumbnail image." For the video captured in steps S32 to S33, the control unit 210 includes in the video management data D2, for example, the video file name received from the digital camera 100, the user rating acquired in step S35, and the timer period set in step S31. Furthermore, when a user operates the marking button 48, the control unit 210 identifies the timing of the user operation during the video capture time and includes it as marker information in the video management data D2.

[0150] Furthermore, the control unit 210 generates a thumbnail image of the video being captured, for example, based on the live view image 45 received from the digital camera 100 via the communication unit 250 in steps S32 to S33, and includes the thumbnail image in the video management data D2 (S38). For example, if the timer period is "OFF," the thumbnail image is composed of a frame image taken at the timing when the record button 46 is operated. If the timer period is set to something other than "OFF," the thumbnail image is composed of a frame image taken at a timing the set timer period has elapsed since the record button 46 was operated.

[0151] The control unit 210 stores the generated moving image management data D2 in the moving image management data list for the cut associated with the moving image in the cut division data D1 (FIG. 6) (S38). For example, the moving image management data D2 for cut number N is stored and managed in the moving image management data list for cut number N in order of the number of takes, as shown in FIG. 15. This storage order is realized, for example, as a result of arranging the moving image files in ascending order.

[0152] The control unit 210 ends the recording mode process (S5) by storing the video management data D2 (S38), for example, and proceeds to step S1 in FIG.

[0153] According to the above-described recording mode process (S5), the system 10 can shoot and record one take of a video for the selected cut and prompt the user to rate it (S32-S35). The system 10 also manages the shooting completion flag for the cut based on the acquired evaluation information (S36, S37). In this way, the user's evaluation information for each take can be appropriately reflected in managing whether or not the cut is in a shooting completion state. Furthermore, according to the recording mode process (S5) of this embodiment, the information support terminal 200 can control the shooting and recording of the video by the digital camera 100, thereby realizing management of video shooting.

[0154] In steps S32 and S33, control unit 210 of information support terminal 200 may record, in storage unit 220 of information support terminal 200, a video file showing live view images 45 sequentially received from digital camera 100 after operation of record button 46. The video file may include audio data collected by microphone 160 in synchronization with video shooting by digital camera 100. Control unit 210 may also determine a file name for the video file based on, for example, cut data D1, and may include the determined file name in an instruction to digital camera 100.

[0155] In rating each take of a video (S34-S35), multiple takes associated with the same scene may have the same rating. For example, multiple takes of the same scene may have a rating of "OK."

[0156] The rating screen displayed in step S34 may be displayed as a dialogue. For example, control unit 210 may control display unit 240 to superimpose the dialogue of the rating screen on the display screen before and after step S33.

[0157] The recording standby screen in recording mode (FIG. 14(A)) may further include a back button 15 for returning the screen transition to, for example, the cut selection screen. Such a back operation may be a swipe operation in a predetermined direction among the ±X directions on the video management screen. The information support terminal 200 may also transition to playback mode by a swipe operation in the opposite direction.

[0158] 2.2.4. Playback mode and review function for cut mistakes The playback mode processing in step S6 in FIG. 8 will be described with reference to FIGS. 16 and 17. In the recording mode described above, a video is shot and recorded in association with a cut selected by the user. If the user makes a mistake in selecting a cut when shooting such a video, the shot video may be associated with a cut that does not match the user's intention, which may cause problems in the subsequent video production workflow. Therefore, the present system 10 provides a function for reviewing video management for each cut, for example, in playback mode.

[0159] Fig. 16 is a flowchart illustrating the process (S6) in the playback mode in the present system 10. Fig. 17 is a diagram showing a display example in the playback mode of the information support terminal 200. Fig. 18 is a diagram for explaining the details of the display example in the playback mode.

[0160] The process shown in the flow of FIG. 16 is started, for example, when an operation to switch to playback mode is input on the cut selection screen (FIG. 7) (S3 (III)). FIG. 17(A) shows an example of the display of the video management screen in playback mode. FIG. 17(B) shows an example of the display of the video playback screen in playback mode. FIG. 17(C) shows an example of the display of the selection menu 52a in playback mode.

[0161] First, the control unit 210 of the information support terminal 200 performs a cut list generation process (S50) for, for example, playback mode based on the selected cut and cut division data D1, and transitions the display unit 240 to a screen for managing moving images for each cut (S51). An example of the display on the information support terminal 200 in step S51 is shown in FIG. 17(A).

[0162] 17(A) shows an example of a video management screen in which a cut with cut number "1" is selected. The video management screen includes, for example, a cut list 51 for playback mode, a video list 50, a menu button 52, and a back button 15. The cut list 51 for playback mode includes, for example, a plurality of cut icons 51a, similar to the cut list 30 of the cut selection screen (FIG. 7), and indicates the currently selected cut by highlighting one of the icons. The video list 50 includes video icons 5 that indicate videos for each take of the currently selected cut.

[0163] FIG. 18(A) shows an example of a cut list 51 for playback mode on the video management screen of FIG. 17(A). An example of a cut icon 51a in the cut list 51 is shown. In the cut list 51 for playback mode, the cut icon 51a includes, for example, a cut number column 51b indicating the identification information of the corresponding cut, and a cut folder 51c, which is a folder-shaped operation icon. For example, in the cut folder 51c, the cut icon 51a displays the storyboard composition of the corresponding cut based on the composition information of the cut division data D1 (see FIG. 5B). The cut icon 51a also indicates whether or not the corresponding cut has been shot, for example, by using the color in the cut number column 51b.

[0164] In step S50, the control unit 210 performs, for example, processing similar to the cut list generation processing (S1 in FIG. 8) described above to generate a cut list for playback mode 51. In this cut list generation processing (S50), when performing processing similar to steps S10 to S19 in FIG. 10, for example, the control unit 210 generates a cut icon 51a for playback mode instead of the cut icon 3 in step S12.

[0165] Fig. 18(B) shows an example of the display of the video list 50 on the video management screen of Fig. 17(A). The video icon 5 includes, for example, a thumbnail image of the video in the take, rating information, and video file name. In step S51, the control unit 210 references, for example, the video management data list for the cut in the cut division data D1, and generates each video icon 5 so as to visualize the rating information for each take associated with the cut. The control unit 210 arranges the video icons 5, for example, in ascending order of the video file names, to generate the video list 50 (S51).

[0166] 17(A), for example, the control unit 210 accepts various user operations via the operation unit 230. The user operations that are the subject of step S52 include (I) a playback selection operation, (II) a re-rating operation, (III) a cut movement operation, (IV) an operation to switch to recording mode, (V) a cut selection operation, and (VI) a back operation.

[0167] The playback selection operation ((I) of S52) is a user operation for selecting a video file to be played and displayed, for example, an operation of tapping a desired video icon 5 in the video list 50 displayed on the video management screen.

[0168] On the video management screen (FIG. 17(A)), the menu button 52 accepts a touch operation to switch between displaying and hiding a selection menu 52a (FIG. 17(C)), for example, in playback mode. The selection menu 52a includes, as options selectable by the user, menu items corresponding to, for example, (II) to (IV) of step S52.

[0169] The re-rating operation ((II) of S52) is a user operation for re-rating a video file. This operation is, for example, a touch operation in which the user presses the menu button 52, selects the corresponding option "Re-rating" in the selection menu 52a, and then taps the desired video icon 5.

[0170] The cut move operation ((III) of S52) is a user operation for starting a change of a cut associated with a video in the present system 10. This operation is, for example, a touch operation of selecting the corresponding option "cut move" in the selection menu 52a from the menu button 52. When a user of the present system 10 finds a video icon 5 with an incorrect cut association, for example, from the video list 50 on the video management screen, the user can input the cut move operation ((III) of S52).

[0171] When a cut movement operation is input ((III) of S52), the control unit 210 executes a cut movement process (S55), which is a process for changing the association between cuts and videos in response to a user operation. In the cut movement process (S55) of this embodiment, a user operation for moving a video icon 5 between cut folders 51c is accepted, and management of the association between cuts and videos is updated in, for example, the cut division data D1. Details of the process of step S55 will be described later.

[0172] After the cut movement process (S55), the control unit 210 performs the processes from step S50 onwards again, for example. In this way, the cut movement process (S55) updates and displays, for example, the cut list 51 for playback mode and the video management screen (S50 to S51).

[0173] In step S52, the control unit 210 accepts an operation to transition to the recording mode (S52 (IV)), for example, similar to (II) of step S3 in FIG. 8. The operation to transition to the recording mode (S52 (IV)) from the video management screen (FIG. 17 (A)) is, for example, a touch operation to select a corresponding option in the selection menu 52a from the menu button 52. Alternatively, this operation may be a swipe operation in a predetermined direction of the ±X directions on the video management screen. The option corresponding to (IV) of step S52 in the selection menu 52a may be omitted.

[0174] When an operation to switch to the recording mode is input ((IV) of S52), the control unit 210 performs the recording mode process (S56) similar to, for example, step S5 in Fig. 8, and then returns to, for example, step S50. In this way, the information support terminal 200 associates the video newly shot in the recording mode with the selected cut, and updates the cut list 51 and the video management screen (S50 to S51).

[0175] Also, in step S52, the control unit 210 accepts a cut selection operation (S52(V)), for example, similar to (I) of step S3 in Fig. 8. The cut selection operation (S52(V)) on the video management screen (Fig. 17(A)) is, for example, a tap operation on the cut icon 51a in the cut list 51 for playback mode.

[0176] When a cut selection operation is input ((V) of S52), the control unit 210 changes the selected cut (S57), for example, in the same manner as in step S4 of Fig. 8, and returns to step S51, for example. In this way, the information support terminal 200 displays the video management screen including the video list 50 of the newly selected cut (S51).

[0177] The back operation in step S52 (VI) is a user operation to return from the playback mode to the function selection screen, for example, the operation of the back button 15 on the video management screen. This operation (S52 (VI)) may be, for example, a swipe operation in the ±X direction on the video management screen in the opposite direction to the operation to transition to the recording mode (S52 (IV)).

[0178] When a playback selection operation is input ((I) of S52) on the video management screen (FIG. 17(A)), the control unit 210 transitions the display unit 240 to a screen for playing and displaying the selected video file, and performs processing for video playback (S53). An example of the display on the information support terminal 200 in step S53 is shown in FIG. 17(B).

[0179] 17(B), the playback screen in step S53 includes a playback image 53, a playback control bar 54, a marker button 55, and a back button 15. The control unit 210 accepts various user operations related to the playback screen via the operation unit 230. For example, the user can switch between playing and pausing the video by tapping the playback image 53, or can change the playback position by tapping the playback control bar 54.

[0180] The playback control bar 54 indicates the playback timing of the entire duration of the video, and markers 56 are placed at positions indicating specific timings. For example, the control unit 210 places the marker 56 on the playback control bar 54 by referring to the marker information in the video management data D2. On the playback screen of FIG. 17(B), the user can place a new marker 56 by operating the marker button 55, or change the position of the marker 56 by dragging it. Upon receiving such various marker operations, the control unit 210 updates the marker information in the video management data D2 in accordance with the marker operations.

[0181] Furthermore, when a user instruction to end playback of the video is input, for example by operating the back button 15, the control unit 210 transitions the display unit 240 from, for example, the playback screen (Figure 17(B)) to the video management screen (Figure 17(A)), and returns to step S52.

[0182] Furthermore, when a re-rating operation ((II) of S52) is input on the video management screen (FIG. 17(A)), the control unit 210 performs processing for re-rating (S54). For example, the control unit 210 first causes an operation screen similar to the rating screen (FIG. 9) to be displayed on the display unit 240, and accepts user operations on the various buttons 41 to 43 as options for the user's rating. In this way, the control unit 210 obtains rating information indicating the re-rating result for the take of the video icon 5 selected by the user in (II) of step S52 (S54).

[0183] In step S54, the control unit 210 updates, for example, the cut division data D1 based on the evaluation information of the acquired re-rating result. For example, the control unit 210 rewrites the evaluation information of the take in the video management data list of the selected cut, or manages the shooting completion flag of the selected cut taking the re-rating result into consideration. For example, when the re-rating changes the evaluation information of all takes associated with the selected cut from "NG" to "KEEP" or "OK," the shooting completion flag is switched from OFF to ON.

[0184] Thereafter, the control unit 210 returns to step S50 and updates the cut list 51 and the moving picture list 50 on the moving picture management screen so as to reflect the re-rating result (S50 to S51).

[0185] For example, when a back operation ((VI) of S52) is input on the video management screen (FIG. 17(A)), the control unit 210 ends the playback mode process (S6) and returns to step S1 in FIG. 8. In this way, in the subsequent cut list generation process (S1), the cut list 30 on the cut selection screen (FIG. 7) is also updated appropriately.

[0186] According to the above playback mode processing (S6), the user can check various takes of the selected cut in the playback display (S53) and redo the rating based on the confirmation results (S54). Furthermore, the system 10 can accept a user's cut movement operation ((III) of S52) on the video management screen (FIG. 17(A)), for example, and perform a cut movement process (S55), thereby enabling the user to review and easily correct a cut mistake in which a video was associated with an unintended cut.

[0187] Furthermore, in the information support terminal 200 of this embodiment, the video management screen (FIG. 17(A)) includes a cut list 51 that visualizes the storyboard of each cut with cut icons 51a, and a video list 50 that visualizes thumbnail images of each video with video icons 5, as shown in, for example, FIGS. 18(A) and 18(B). It is assumed that the thumbnail images of the videos resemble the storyboard of the cuts intended by the user and differ from the storyboard of unintended cuts. Therefore, the system 10 makes it easy for the user to find videos with incorrect cuts and to consider the destination cuts to correct for the video by comparing the cut icons 51a in the cut list 51 with the video icons 5 in the video list 50 on the video management screen.

[0188] Furthermore, in the playback mode of the system 10, for example, a cut selection operation and an operation to switch to recording mode can be input on the video management screen ((V), (IV) of S52). This allows the user of the system 10 to change the selected cut on the video management screen and check various takes of video across a variety of cuts. Furthermore, if the user finds an additional cut that they would like to shoot as a result of checking the video in playback mode, for example, they can immediately switch to recording mode. This improves the efficiency of the video shooting work by the user of the system 10.

[0189] On the other hand, when switching from the video management screen to the recording mode, video shooting is performed in association with the cut selected immediately before that, so an unexpected transition can result in a cut mistake, where the video is associated with a cut that the user did not intend. In such a case, the information support terminal 200 of this embodiment allows the user to move the video with the incorrect cut to the cut folder 51c of the user's choice by the cut movement process (S55), making it easy to correct the cut mistake.

[0190] The playback mode of the present system 10 is not particularly limited to the above example, and for example, the control unit 210 may not accept the user operations of steps S52 (III) and (IV). In this case, the processes of steps S56 and S57 can be omitted. Furthermore, in the present system 10, the cut movement process (S55) is not particularly limited to a user operation from the video management screen in playback mode (S52 (III)), and may be performed in response to a user operation from various management screens other than the playback mode, for example.

[0191] 2.2.5.Cut and move processing The cut movement processing in step S55 in FIG. 16 will be described in detail with reference to FIGS.

[0192] Fig. 19 is a flowchart illustrating the cut movement process (S55) in the information support terminal 200. Fig. 20(A) to (D) show display examples in the cut movement process (S55).

[0193] First, the control unit 210 of the information support terminal 200 determines the moving image selected as the moving object in response to a user operation on the operation unit 230 (S71). An example of the display on the information support terminal 200 in step S71 is shown in FIG.

[0194] Fig. 20(A) illustrates an example of a selection operation for a moving object that can be input after a cut movement operation ((III) of S52 in Fig. 16) from the video management screen in Fig. 17(A). In response to the operation of (III) of step S52 in Fig. 16, the control unit 210 displays a check box 5a for each moving image icon 5 in the currently displayed moving image list 50, indicating whether or not the moving image icon is a moving object by using an on / off check box, as shown in Fig. 20(A), for example. For example, the initial state of the check box 5a is set to off.

[0195] In the example of FIG. 20(A), in the moving image list 50 of the cut with cut number "1" as the source of movement, the moving images with moving image file names "P1103" and "P1105" are determined as the moving objects (S71). The user can select the moving images to be moved by a tap operation to turn on the check box 5a of the desired moving image icon 5. The control unit 210 accepts the tap operation to turn on the check box 5a on, for example, the touch panel of the operation unit 230 as a selection operation for the moving objects, and determines the selected moving images as the moving objects (S71). The moving image from the source of movement is an example of the first cut in this embodiment.

[0196] Next, the control unit 210 determines the cut to be selected as the destination in response to a user operation on the operation unit 230 (S72). The user can easily select the destination cut, for example, from the storyboard display (FIG. 18(A)) of each cut icon 51a in the cut list 51. An example of the operation of step S72 is shown in FIG. 20(B). The destination cut is an example of the second cut in this embodiment.

[0197] FIG. 20(B) illustrates an example of a destination selection operation in which the cut with cut number "3" is input as the destination after FIG. 20(A). The destination selection operation is, for example, a drag-and-drop operation from the moving image icon 5 to be moved to the cut folder 51c of the user-desired cut in the moving image list 50. The control unit 210 determines the drop-destination cut as the destination in response to, for example, this destination selection operation (S72). This allows the user to easily select the cut to be associated as the result of correcting a cut mistake, i.e., the destination cut, through an intuitively easy-to-understand operation such as moving between cut folders 51c.

[0198] Next, the control unit 210 adds the moving image management data D2 to be moved to the moving image management data list (FIG. 15) of the destination cut in, for example, the cut division data D1 (FIG. 6) based on the information acquired in steps S71 and S72 (S73). An example of the moving image management screen for the destination cut after such correction is shown in FIG. 20(C).

[0199] The video management screen of Fig. 20(C) is displayed in step S51 after the cut movement process (S55) of Fig. 16 as a result of the operation example of Fig. 20(B). In the video list 50 of the destination cut, for example, as shown in Fig. 20(C), the video icon 5 to be moved (see Fig. 20(A)) and the video icon 5 already in the destination cut are arranged in a predetermined order, such as ascending order of video file names (or shooting order). The system 10 may add and update the number of takes of the destination cut according to this order.

[0200] Furthermore, the control unit 210 deletes the moving image management data D2 to be moved, acquired in step S71, from the moving image management data list of the source cut in the cut division data D1 (S74). An example of the moving image management screen for the source cut after such an update is shown in Fig. 20(D).

[0201] The video management screen of Fig. 20(D) is displayed in step S51 after the cut movement process (S55) of Fig. 16 as a result of the operation example of Fig. 20(B), similar to Fig. 20(C). In the video list 50 of the source cut, for example, as shown in Fig. 20(D), the video icon 5 to be moved (see Fig. 20(A)) is deleted, and the remaining video icons 5 are arranged, for example, by spacing them out. The system 10 may delete and update the number of takes of the source cut in this order and manage them.

[0202] Next, the control unit 210 determines whether the highest rating has changed for the destination or source cut, for example, based on the rating information in the video management data list for each destination / source cut before and after the update as described above (S75). The highest rating is the highest rating among the ratings of each video included in the cut. For example, if the cut only contains videos rated "NG," the highest rating is "NG." On the other hand, if the cut contains videos rated "OK" or "KEEP," the highest rating is "OK" or "KEEP."

[0203] In step S75, the control unit 210 calculates the highest rating of the destination cut before and after step S73, for example, and compares them with each other. The control unit 210 also calculates the highest rating of the source cut before and after step S74, and compares them with each other. For example, if the highest rating of at least one of the source cut and the destination cut has changed, the control unit 210 proceeds to "YES" in step S75. If the highest rating has changed between "OK" and "KEEP," the control unit 210 may proceed to "NO" in step S75.

[0204] When the control unit 210 determines that the highest rating of the destination / source cut has changed (YES in S75), it changes the shooting completion flag in the cut division data D1, for example, according to the updated highest rating (S76). By changing the shooting completion flag in this way, the display of the shooting completion status or shooting incomplete status for each cut is updated in the cut list 51 on the video management screen, for example.

[0205] 20(A) to (D), the highest rating of the source cut (cut number "1") has changed from "OK" before the update to "NG" after the update (YES in S75), as shown in Fig. 20(A) and (D). Therefore, the display of the video icon 5 for that cut is changed from a shooting completed state to a shooting incomplete state (S76).

[0206] 20(A) to (D), the highest rating of the destination cut (cut number "3") has also changed (YES in S75). Therefore, the display of the video icon 5 for that cut is changed from an incomplete shooting state to a completed shooting state in step S76 (see FIGS. 20(A) and (C)).

[0207] On the other hand, when the control unit 210 determines that the highest rating of the destination / source cut has not changed (NO in S75), for example, the process of step S76 is not performed and the process proceeds to cut movement processing step S77.

[0208] Next, the control unit 210 stores the cut data D1 updated as a result of the cut movement process (S55) in the storage unit 220 (S77). Thereafter, the control unit 210 ends the cut movement process (S55) and returns to, for example, step S51 in FIG. 16. Thus, in the subsequent step S51, the video management screen (FIGS. 20(C) and (D)) updated by the cut movement process (S55) is displayed.

[0209] According to the above cut movement process (S55), in the information support terminal 200 of this embodiment, the user can change the cut associated with the video at the time of shooting at any timing after shooting, for example, using the video management screen.

[0210] Furthermore, according to the cut movement process (S55) of this embodiment, the shooting completion status is updated in accordance with changes in the highest rating of the source / destination cuts (S75-S76). This allows the system 10 to resolve issues such as an error in the identification display of the shooting completion status for each cut due to, for example, the rating of a video with an incorrect cut, and to appropriately correct the identification display of the shooting completion status for the source / destination cuts (FIGS. 20(A)-(D)). This improves the accuracy of management of the shooting completion status for each cut in the system 10, making it easier to prevent forgetting to shoot each cut.

[0211] Although the above description has been given of an example of the operation of selecting the movement target in step S71, the present system 10 is not particularly limited to this. For example, in step S71, display of the check box 5a may be omitted. For example, the control unit 210 may accept the operation of selecting the movement target one video at a time, or may accept a drag-and-drop operation for each video. In such a case, the operation of selecting the movement target (S71) and the operation of selecting the movement destination (S72) may be input together. Furthermore, in the present system 10, the operation of selecting the movement destination (S72) is not particularly limited to a drag-and-drop operation, and may be any operation for selecting a movement destination cut.

[0212] In addition, in step S75, the control unit 210 may proceed to "YES" if the highest rating changes between "OK" and "KEEP." For example, the system 10 may use different display modes to indicate the shooting completion state when the highest rating is "OK" and when it is "KEEP."

[0213] 2.3. Export function The export function of the information support terminal 200 of the system 10 will be outlined with reference to FIG.

[0214] Fig. 21 shows an example of a video editing screen display on the video editing PC 300 of the system 10. The video editing PC 300 (Fig. 1) loads, for example, management data output from the export function of the information support terminal 200 and video data captured by the digital camera 100 into predetermined editing software, and displays the video editing screen as shown in Fig. 21. The editing software may be various non-linear editing (NLE) software, such as DaVinci Resolve, Adobe Premiere Pro, Final Cut Pro, or Vegas Pro.

[0215] The video editing screen illustrated in Fig. 21 includes a material display field 61, a timeline editing field 62, a metadata display field 63, and a preview image 64. The video editing screen is a screen on which the user performs various video editing operations. The material display field 61 displays a list of video data (i.e., video material) loaded into the video editing PC 300 as video editing material. In the present system 10, for example, the material display field 61 displays a folder for managing video material for each cut, i.e., a video folder 70.

[0216] As shown in FIG. 21, the video folder 70 includes folders for each cut, i.e., cut folders 71, and a KEEP folder 72 and an OK folder 73 provided within each cut folder 71. The KEEP folder 72 stores video files with a rating of "KEEP" among the video material for that cut. The OK folder 73 stores video files with a rating of "OK" among the video material for that cut. With the export function of the system 10, the control unit 210 automatically writes a directory structure for realizing such a configuration of the video folder 70 into the management data.

[0217] The timeline editing field 62 displays a video timeline 80 including a plurality of video materials arranged on a time axis 81, and accepts user operations for editing a video work combining the video materials on the video timeline 80. The video timeline 80 has tracks for each row in which the video materials are arranged along the time axis 81. On the video timeline 80, the plurality of tracks are arranged in a direction V that intersects with the time axis 81, and different video materials can be arranged at the same position on the time axis 81.

[0218] The video timeline 80 includes, for example, a preset number of video tracks and audio tracks corresponding to each video track. The video tracks include video clips for each cut in the video file. The audio tracks include audio clips for each cut in the video file.

[0219] The metadata display field 63 displays metadata of the video material displayed in the material display field 61 or the timeline editing field 62. The preview image 64 displays an image of the video material at a timing corresponding to the position of a playback head 82 arranged on a time axis 81 in a video timeline 80.

[0220] For example, on the video editing screen (FIG. 21), the user can adjust the arrangement of video materials in the timeline editing field 62 while checking the preview image 64, or place new video materials in the material display field 61 on the video timeline 80. These user operations are used to edit the video work in the system 10.

[0221] In order to facilitate the user's editing of the video work as described above, the information support terminal 200 of this embodiment generates management data for systematically managing video materials in an export function that reflects the cuts and the user's evaluations after the cut shooting function is executed. This facilitates the video editing process by the user in the system 10, and ultimately improves the processing efficiency of the video editing process by the video editing PC 300.

[0222] In such an export function, if a cut error occurs when shooting a video for each cut before execution of the export function, a problem may occur in which the video material is not arranged as intended by the user in the video folder 70 or the video timeline 80. In contrast, the cut movement process (S55) of this embodiment makes it possible to correct the cut error that causes the problem before execution of the export function, making it easier to realize information support in line with the user's intentions in the video folder 70 or the video timeline 80.

[0223] 3. Summary As described above, in this embodiment, information support terminal 200, an example of an electronic device, manages video shooting for a scenario including multiple cuts. Information support terminal 200 includes display unit 240 that displays information, operation unit 230, an example of an input unit that inputs user operations, and control unit 210 that controls display unit 240 in response to operations input via operation unit 230. After a video associated with a first cut of the multiple cuts has been shot, control unit 210 changes the cut to be associated with the shot video to a second cut different from the first cut in response to user operations via the input unit (see FIGS. 19 and 20 ).

[0224] With the above-described information support terminal 200, for example, a user can change the association from a first cut that the user mistakenly associated with a video to a second video that the user intended. In this way, the information support terminal 200 of this embodiment allows the user to eliminate mistakes in cutting videos and reduces management errors caused by using multiple cuts in video shooting.

[0225] In the information support terminal 200 of this embodiment, the control unit displays a moving image list 50, which is an example of a first list showing moving images associated with a first cut, on the display unit 240, and receives a user operation at the operation unit 230 to select a moving image from the moving image list 50 whose associated cut is to be changed (S71, see FIG. 20(A)). This allows the user to select a desired moving image to be moved from the moving image list 50, making it easier to reduce management errors such as incorrect cutting.

[0226] In the information support terminal 200 of this embodiment, the control unit 210 displays a cut list 51, which is an example of a second list showing a plurality of cuts, on the display unit 240 together with the moving image list 50 (see FIGS. 20(A) to 20(D)). The control unit 210 accepts a user operation at the operation unit 230 to select a second cut from the cut list 51 as the destination cut (S72, see FIG. 20(B)), and changes the cut to be associated with the moving image selected from the first list to the second cut (S73 to S74, see 20(C) to 20(D)). This allows the user to select an appropriate cut from the cut list 51 as the destination cut, making it easier to reduce management errors such as selecting the wrong cut.

[0227] In the information support terminal 200 of this embodiment, the moving image list 50 lists images such as thumbnail images showing the shooting results of each moving image associated with each cut, using moving image icons 5, as shown in Fig. 18(B), for example. The cut list 51 lists subject information related to subjects set for each cut, such as the composition of a storyboard, using cut icons 51a, as shown in Fig. 18(A), for example. The user of the present system 10 can easily check and correct cut errors from these lists 50 and 51.

[0228] In the information support terminal 200 of this embodiment, before shooting a video, the control unit 210 causes the display unit 240 to display a cut selection screen (FIG. 7), which is an example of a selection screen including a plurality of cuts, and accepts a user operation on the operation unit 230 to select a specific cut from the multiple cuts (S1 to S3). When a video associated with a specific cut is shot, the control unit 210 causes the display unit 240 to display a rating screen (FIG. 9), which is an example of an evaluation screen that prompts the user to evaluate the video, and acquires evaluation information indicating the user's evaluation of the video from the operation unit 230 (S32 to S35).

[0229] According to the above-described information support terminal 200, when a video of a take associated with a specific cut selected by the user is shot, the user's evaluation of the video of that take is obtained, thereby making it easier to manage video shooting in a scenario including multiple cuts.

[0230] In the information support terminal 200 of this embodiment, the control unit 210 sets the cut list 30 on the cut selection screen in accordance with the acquired evaluation information so as to identify whether video shooting of a specific cut associated with a video whose evaluation information indicates the user's evaluation has been completed (S5, S1, see FIG. 7). This allows the user to visualize whether video shooting has been completed for each cut on the cut selection screen, thereby preventing the user from forgetting to shoot a video.

[0231] In the information support terminal 200 of this embodiment, when the cut associated with the shot video is changed, for example, from the first cut to the second cut, the control unit 210 updates the cut division data D1 and, ultimately, the selection screen in accordance with the evaluation information of the video associated with each cut after the change (S75 to S77). This allows the management of the shooting completion status to be corrected by eliminating the cut mistake, thereby improving the accuracy of preventing forgetting to shoot.

[0232] In the information support terminal 200 of this embodiment, the control unit 210 determines that video shooting of a specific cut has not been completed when the evaluation information for all videos associated with the specific cut indicates an evaluation of "NG," which is an example of a first evaluation (YES in S36, NO in S13, S15). The control unit 210 determines that video shooting of a specific cut has been completed when the evaluation information for at least one video associated with the specific cut indicates an evaluation of "OK" or "KEEP," which is an example of a second evaluation different from the evaluation of "NG" (NO in S36, YES in S13, S14). This determines that video shooting of a cut associated with only videos of takes rated "NG" by the user has not been completed, making it easier to manage the completion of video shooting in accordance with the user's intentions.

[0233] In the information support terminal 200 of this embodiment, the control unit 210 has a playback mode in which a shot video is played back and displayed on the display unit 240 (see FIG. 17). In the playback mode, the control unit 210 changes the cuts associated with the shot video in response to a user operation on the operation unit 230 (see FIG. 16). This allows the user of the present system 10 to correct any video with a wrong cut when checking the video in playback mode, making it easier to reduce management errors such as wrong cuts.

[0234] In the information support terminal 200 of this embodiment, the control unit 210 accepts a user operation to select a shooting location for video shooting on the operation unit 230 (see FIG. 11), and updates the cut selection screen to narrow down the number of cuts according to the selected shooting location (S7, S1). This allows the user to use the cut selection screen by narrowing down the options to a desired shooting location, making it easier to manage video shooting.

[0235] In the information support terminal 200 of this embodiment, the control unit 210 accepts an operation to add an additional cut from multiple cuts in a scenario at the operation unit 230, and updates the cut selection screen to include the additional cut (S8, S1, see FIG. 12). This allows the user to add cuts outside the scenario and use the cut selection screen, making it easier to use the cut photography function.

[0236] In this embodiment, information support terminal 200 further includes storage unit 220 for storing cut division data D1, which is an example of management information for managing videos associated with multiple cuts in a scenario. Control unit 210 updates the management information in response to user operations on operation unit 230 to change the cuts associated with the shot video (S71 to S77). In this way, information support terminal 200 of this embodiment can reduce management errors when multiple cuts are used in video shooting.

[0237] In this embodiment, the information support terminal 200 further includes a communication unit 250 that performs data communication with the digital camera 100, which is an example of an imaging device that performs video shooting. The control unit 210 manages the video shot by the digital camera 100 through data communication via the communication unit 250 (S5). This makes it easier to manage the video shooting for each cut in the information support terminal 200, which is separate from the digital camera 100.

[0238] In this embodiment, a video management method for managing video shooting including multiple cuts is provided. This method includes a step (S56) in which the control unit 210 of the information support terminal 200 controls shooting of a video in association with a first cut of the multiple cuts, and a step (S55) in which, after the video associated with the first cut has been shot, the cut to be associated with the shot video is changed to a second cut different from the first cut in response to a user operation on the operation unit 230.

[0239] In this embodiment, a program is provided to cause the control unit 210 to execute the above-described video management method. This video management method can reduce management errors caused by using multiple shots in video shooting. The control unit 210 may control the display unit 240 to display information related to video shooting including multiple shots, in response to an operation input by the user via the operation unit 230.

[0240] (Embodiment 2) A second embodiment of the present disclosure will be described below with reference to Figs. 22 to 24. In the first embodiment, an imaging system 10 that performs a cut movement process on a video containing a cut error found by a user has been described. In the second embodiment, an imaging system 10 that automatically detects a video containing a cut error will be described.

[0241] Hereinafter, the description of the same configurations and operations as those of the imaging system 10 and the information support terminal 200 according to the first embodiment will be omitted as appropriate, and the imaging system 10 and the information support terminal 200 according to this embodiment will be described.

[0242] 23 is a diagram for explaining the automatic detection process in the imaging system 10 of embodiment 2. When performing the same operation as the imaging system 10 of embodiment 1, the system 10 automatically detects videos with incorrect cuts by, for example, using image recognition to compare storyboards for each cut with individual videos.

[0243] Fig. 23 is a flowchart illustrating an example of automatic detection processing in the imaging system 10 of embodiment 2. The processing shown in the flow of Fig. 23 is executed, for example, by the control unit 210 of the information support terminal 200. The processing of this flow is started, for example, after the same recording mode processing (S56) as in embodiment 1 is performed, and is performed with the video of the take shot in the recording mode as the detection target.

[0244] First, the control unit 210 of the information support terminal 200 acquires object information for, for example, a storyboard of a cut associated with a moving image to be detected (S80). Such storyboard object information is exemplified in Fig. 22(A).

[0245] In the example of Figure 22(A), the storyboard for the cut includes one object 90 of the type "person" and multiple objects 91-93 of another type "vehicle" that are positioned further back than the object 90. The object information in the example of Figure 22(A) includes the number of objects 90-93 of each type and their relative positions. This storyboard object information is set, for example, when the storyboard for the cut is input using the scenario creation function of the present system 10, is stored in the storage unit 220, and is read out in step S80.

[0246] Furthermore, the control unit 210 recognizes object information in the moving image to be detected, for example, based on a thumbnail image of the moving image (S81). Examples of the thumbnail image in step S81 are shown in Figures 22(B) and (C).

[0247] Figure 22(B) shows an example of a thumbnail image of a video that is correctly associated with the cut in Figure 22(A). Figure 22(C) shows an example of a thumbnail image of a video that is erroneously associated with the cut in Figure 22(A).

[0248] For example, in step S81, the control unit 210 performs image recognition processing on the thumbnail image using image recognition AI previously acquired through machine learning to recognize the number, type, position, size, and positional relationships between the subjects in the thumbnail image. The position of the subject may include the position in the depth direction in addition to the two-dimensional position on the thumbnail image. For example, the positional relationships in the depth direction can be recognized based on the size of the subject in the thumbnail image and the overlap between the subjects.

[0249] For example, from the thumbnail image shown in Fig. 22(B), object information similar to that of the objects 90 to 93 in the storyboard of Fig. 22(A) in terms of the positional relationship of the subjects is recognized (S81). On the other hand, from the thumbnail image shown in Fig. 22(C), object information different from that of the objects 90 to 93 in the storyboard of Fig. 22(A) in terms of the positional relationship of the subjects and the number of each type is recognized (S81).

[0250] Next, the control unit 210 determines whether the storyboard and the thumbnail image are similar, for example, based on the object information of the storyboard of the cut associated with the video to be detected and the object information recognized from the thumbnail image of the video (S82).

[0251] The process of step S82 is performed using, for example, a similarity that indicates the degree to which the object information is similar to each other. For example, in the example of FIG. 22(B), a relatively high similarity is calculated. On the other hand, in the example of FIG. 22(C), a lower similarity is calculated than in the case of FIG. 22(B). The control unit 210 calculates, for example, the above-mentioned similarity and compares the calculated similarity with a predetermined threshold value (S82). The threshold value is set, for example, as a standard for a similarity that is small enough to be considered a cutting error, and is, for example, equal to or greater than the similarity of FIG. 22(C) and less than the similarity of FIG. 22(B).

[0252] If the control unit 210 determines that the thumbnail image of the video to be detected is not similar to the storyboard of the cut associated with the video (NO in S82), it detects the video as a target for warning about a wrong cut, and turns on a warning flag, for example (S83).

[0253] 22(C), the similarity is equal to or less than the threshold value, so control unit 210 proceeds to NO in step S82. The warning flag in step S83 is managed, for example, for each captured video file, and indicates by ON / OFF whether the video is subject to a warning for incorrect cutting. For example, the warning flag is managed in storage unit 220 with its initial value set to OFF.

[0254] When the control unit 210 turns on the warning flag as a result of the detection of an incorrect cut (S83), it ends the automatic detection process shown in Fig. 23. An example of the display on the information support terminal 200 when the warning flag is turned on in this way is shown in Fig. 24.

[0255] On the other hand, if the control unit 210 determines that the storyboard and the thumbnail image are similar (YES in S82), it does not detect the video as a target for a warning about a wrong cut, and ends the automatic detection process in Fig. 23. For example, in the example of Fig. 22(B), since the similarity is greater than the threshold value, the control unit 210 proceeds to YES in step S82. In this case, the warning flag for the video is maintained OFF.

[0256] According to the automatic detection process (FIG. 23) in the present system 10 described above, it is possible to detect the target of a warning for a wrong cut from the similarity between the storyboard and thumbnail images of the cut associated with the video, as shown in, for example, FIGS. 22(A) to 22(C) (S82 to S83).

[0257] The information support terminal 200 of this embodiment notifies the user of the detected videos that are subject to a warning on the video management screen after the automatic detection process (FIG. 23), as shown in, for example, FIG. 24. In this embodiment, when performing playback mode processing similar to that of the first embodiment, the control unit 210 of the information support terminal 200 refers to the warning flag in step S51 of FIG. 16 and adds a highlight 5b, such as a frame, to the video icon 5 whose warning flag is ON.

[0258] In this way, the user of the system 10 can check videos that may have a cut error on the video management screen of Fig. 24, for example, and consider whether to perform cut movement processing. When cut movement processing is performed on a video that is the subject of a warning, for example, the control unit 210 resets the warning flag for that video to OFF.

[0259] In the above description, an example has been described in which the automatic detection process is executed after the process in the recording mode. The automatic detection process of this embodiment is not particularly limited to this, and may be executed in, for example, the playback mode. For example, the control unit 210 may execute the automatic detection process for the destination (or source) cut after the cut movement process in the playback mode.

[0260] In this embodiment, the automatic detection process may be performed on multiple takes of video, or on multiple cuts. For example, when a video with a wrong cut is detected, the control unit 210 may automatically detect a cut that is expected to be the destination of the video. Such automatic detection may be performed in the same manner as the automatic detection process described above, for example, by comparing object information of various cuts with object information of the video with the wrong cut.

[0261] Furthermore, in the above step S50, the object information of the cut does not need to be stored in advance in the storage unit 220, and for example, the control unit 210 may acquire the object information by performing image recognition on the image information of the storyboard. Furthermore, in the above step S51, the input for image recognition is not limited to thumbnail images of the video, but may be various images in the video.

[0262] Furthermore, the automatic detection process of this embodiment is not limited to a comparison of object information, and may be performed by determining similarity through various image recognition methods. The control unit 210 of the information support terminal 200 may detect videos with incorrect cuts by, for example, transmitting information about the videos and cuts to be compared to an external server and receiving image recognition results in response.

[0263] As described above, in the information support terminal 200 of this embodiment, the control unit 210 detects a video whose associated cut from the first cut should be changed (S82-S83) based on the result of image recognition of the subject in the video associated with the first cut (S81) and the subject information about the subject set in the first cut (S80). This allows the information support terminal 200 of this embodiment to automatically detect videos with incorrect cuts, making it easier to reduce management errors.

[0264] In the information support terminal 200 of this embodiment, when the control unit 210 detects a video whose associated cut should be changed from the first cut (YES in S83), it notifies the user of the detected video (S84). The control unit 210 may control the display unit 240 to notify the user of the detected video, for example, as shown in Fig. 24. In this way, the user of the present system 10 can consider whether or not to move the cut of the detected video, making it easier to reduce management errors in accordance with the user's intentions.

[0265] (Other embodiments) As described above, the first and second embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to these, and can be applied to embodiments in which appropriate modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the above embodiments to create new embodiments.

[0266] In the above-described first and second embodiments, the information support terminal 200 has been described as an example of an electronic device separate from an imaging device, but the present disclosure is not limited to this. The electronic device of the present embodiment may be integrated with an imaging device that captures video. Such a modification will be described with reference to FIG. 25.

[0267] 25 illustrates a modified example of the digital camera 100. In this embodiment, the digital camera 100 has various functions, such as the cut shooting function of the information support terminal 200 described above. For example, as shown in FIG. 25, the control unit 135 of the digital camera 100 displays a cut selection screen including multiple cuts based on a cut list 30 on the display monitor 130, and accepts cut selection by the user via the operation unit 150, such as a touch panel or operation buttons.

[0268] In the example of Fig. 25, the display monitor 130 displays a cut list 30 superimposed on a live view image. The control unit 135 of the digital camera 100 generates video data, for example, by the imaging operation of the image sensor 115. As with the recording mode processing of the first embodiment (Fig. 13), when a video of a selected cut is shot, the control unit 135 of the digital camera 100 displays a rating screen (Fig. 9) on the display monitor 130 and acquires user evaluation information. As with the first embodiment, this digital camera 100 can also provide the user with information support using the cut shooting function.

[0269] As described above, in this embodiment, the digital camera 100, which is an example of an electronic device, further includes the image sensor 115, which is an example of an imaging unit that captures an image of a subject and generates image data. The control unit 135 manages a video composed of the image data generated by the image sensor 115. This makes it easier to manage video shooting for each cut in the digital camera 100. Furthermore, such an electronic device is not limited to the digital camera 100, but may be various information terminals. For example, the information support terminal 200 may include the image sensor 115, and the results of shooting by the image sensor 115 may be managed in the same way as in the first and second embodiments.

[0270] In each of the above embodiments, the source / destination cuts are exemplified as examples of the first / second cut (FIGS. 20(A) to (D)). In this embodiment, the first cut and the second cut are not limited to one each, and may be a group of multiple cuts. For example, in this system 10, a video to be shot may be associated with a group of cuts. Even in this case, this system 10 can reduce management errors in shooting a video that includes multiple cuts by using a function for reviewing incorrect cuts, as in each of the above embodiments.

[0271] In each of the above embodiments, a cut selection screen including a cut list 30 has been exemplified, but the selection screen of the present disclosure is not limited to this. The selection screen of the present embodiment may not include the cut list 30, and may include multiple cuts in a display format different from the cut icon 3. Furthermore, the selection screen of the present embodiment may be a dialog display, or may be displayed superimposed on various display screens. In the present embodiment, the cut list 30 may be an example of a selection screen. In the present embodiment, the selection screen of the information support terminal 200 may distinguish whether or not video shooting has been completed for each cut in various display formats not limited to the above examples.

[0272] In the above embodiments, examples have been described in which the evaluation information is three types, "OK," "KEEP," and "NG," but the evaluation information is not particularly limited to these. In this embodiment, the evaluation information may be three types of evaluation different from the above, or may be two or four or more types instead of three. Furthermore, in this embodiment, the evaluation information may be a continuous score. The electronic device of this embodiment may accept user input of such various types of evaluation information and manage video shooting for each cut. For example, by appropriately setting criteria for whether or not video shooting of a cut has been completed, it is possible to display the completion of the video shooting.

[0273] Furthermore, in each of the above embodiments, the digital camera 100 is illustrated as including the optical system 110 and the lens driving unit 112. The imaging device of this embodiment does not necessarily have to include the optical system 110 and the lens driving unit 112, and may be, for example, an interchangeable lens camera.

[0274] Furthermore, in each of the above embodiments, a digital camera has been described as an example of an imaging device, but the present disclosure is not limited to this. The imaging device of the present disclosure may be any electronic device having an image capturing function (for example, a video camera, a smartphone, a tablet terminal, etc.). Furthermore, the electronic device of the present disclosure does not necessarily have to have an image capturing function, and may be any of various electronic devices.

[0275] (Example) Various aspects of the present disclosure will be exemplified below.

The electronic device includes a display unit that displays information related to video shooting including multiple cuts, an input unit that inputs user operations, and a control unit that controls the display unit in response to the operation input via the input unit. After a video associated with a first cut of the multiple cuts is shot, the control unit changes the cut to be associated with the shot video to a second cut different from the first cut in response to the user operation via the input unit.

[0277] In a second aspect, in the electronic device described in the first aspect, the control unit displays a first list showing videos associated with a first cut on the display unit, and accepts a user operation at the input unit to select a video from the first list to change the associated cut.
