First, the user selects the original media as an editing target by using a video editing application, and the processor 120 may load the selected original media into the image display window 401 and the clip display window 404 of the image project ( S205). The original media may include at least one of still images, moving images, and audio. In the present disclosure, the clip display window 404 may be exemplified as a clip setting area.

The clip display window 404 may set a clip related to the original media as an initial main clip, and load the initial main clip into the main clip line 404a illustrated in FIG. 4 . The main clip line 404a may represent the original media related to the initial main clip as frames with a predetermined interval. Also, the user may add another initial main clip to the main clip line 404a by selecting other original media following the initial main clip. In the present disclosure, for convenience of description, the main clip loaded on the main clip line 404a will be described in combination with the original media or the main media.

Next, as illustrated in FIG. 7A , according to a user's trim request for the original media loaded in the clip display window 404, the processor 120 may generate the trim media 602a to 602c. (S210).

The trimmed media 602a to 602c may be media processed so that at least a portion of the original media is selected in response to a user's trim request and maintained as the edited content of the project, and the unselected part is not included in the edited content. 7A exemplifies a plurality of trim media 602a to 602c maintained by cutting the initial main clip, and the trim media 602a to 602c may be used interchangeably as the main trim media or the main clip in the present disclosure. In addition, for convenience of description in the present disclosure, the plurality of main trim media 602a to 602c may be respectively referred to as first to third main trim media 602a to 602c.

A plurality of the first to third main trim media 602a to 602c may be extracted from one original medium, or media extracted from the plurality of original media may be continuously combined to generate the first to third main trim media 602a to 602c.

When the original media 610 is a still image, as illustrated in FIG. 7B , the main trim media 612 may be set as a trim region of a still image spatially designated by the user in the original media. Spatial designation may be realized, for example, by a user's designated gesture for the original media 610 displayed on the image display window 401 and/or manipulation of a tool related to space designation.

When the original media 620 is a moving picture, as illustrated in FIG. 7C , the main trim media 622 is set as a trim area of the moving picture designated by the user for at least one of a time section and a space in the original media 622 . can be In order to indicate that the original media 620 illustrated in FIG. 7C is a moving picture, the movement of the object is illustrated as being developed for each frame.

The trim request related to the time period selected by the user may be performed, for example, by the user's gesture touch input on the provided initial main clip of the main clip line 404a and/or manipulation using a trim tool. More specifically, by a gesture touch input to adjust the window of the initial main clip of the main clip line 404a illustrated in FIG. 4 and/or manipulation using a tool in the trim/split menu 501 illustrated in FIG. 5A , The user may retain at least a portion of the original media 620 in the edited content.

In addition, if the original media 620 associated with each main trim media 602a-602c is maintained, the user can re-edit each main trim media 602a-602c. In this case, the processor 120 may provide the initial content of the original media 620 so that the user can check all of the original media 620 . Specifically, even if each main trim media 602a to 602c is generated by a primary trim request, another section of the original media 620 not included in the main trim media 602a to 602c is included in the edited content, To exclude a section of the original media 620 that is already included, the user can readjust the trim. For example, the user adjusts the window of the main clip of each main trim media 602a - 602c provided in the clip display window 404 , so that the processor 120 generates an initial main clip containing the entirety of the original media 620 . can provide The user can check the whole of the original media 620 by the initial main clip. The user re-executes a trim request in the initial main clip, and the processor 120 may change the firstly generated main trim media 602a to 602c. In another embodiment, the user releases the tool of the trim/split menu 501 in which each of the main trim media 602a to 602c is cut, so that the processor 120 restores the original media 620 and the user's trim It is also possible to regenerate main trim media upon re-request.

The trim request related to the space of the area selected by the user is similar to the spatial designation of a still image, the user's designated gesture for the original media 620 displayed on the image display window 401 and/or the manipulation of a tool related to space designation. can be realized by The main trim media 622 according to the spatial trim request may also be re-edited similarly to the above-described process.

The trim request in which the time period and the space are all specified may be performed by combining the above-mentioned items.

In relation to trimming of a video, the processor 120 may identify at least one of a time section requested by the user to trim the original media 620 and a start and end point of the section. For example, the processor 120 identifies an I-Frame (Infra-Frame) of the original media 620 associated with each point, and trims the original media 620 by employing the I-Frame as a trim start point. can When describing an I-Frame, when a moving picture is compressed, data of a previous time, for example, preceding image data may be used. However, in the I-Frame, the moving image may be compressed without using preceding image data. Accordingly, the moving picture starts from the I-Frame and the I-Frame is inserted at the middle point of the corresponding image, so that the processor 120 may search for and reproduce the moving picture at the corresponding position.

When the trim processing proceeds based on the point requested by the user regardless of the I-Frame of the original media 620 , the processor 120 decodes the original media 620 and re-encodes the original media 620 into a desired format. processing should be performed. As in the embodiment of the present disclosure, when the original media 620 is trimmed using an I-Frame, the trim process does not involve transcoding, and the image data before the I-Frame is deleted simply and quickly. can be implemented. Deletion of image data before I-Frame may utilize, for example, a method of modifying some metadata.

Meanwhile, the processor 120 may perform editing to add content to the main trim media 602a to 602c in response to a user's request for adding content to the main trim media 602a to 602c. For example, the elements constituting the content may be, for example, an image frame, a voice, music, an effect, an image frame, text, an overlapping layer, and the like. The content to be added may be sub media in terms of being added to the main trim media. It may be confirmed through the image display window 401 , the sound output device 155 , and the clip display window 404 . The clip display window 404 may provide, for example, a sub clip line 404b illustrated in FIG. 4 , and the sub clip line 404b may present various information related to the added content. More specifically, the sub clip line 404b may visually provide sub clips 604a to 604d for each added content, as illustrated in FIGS. 4 and 7A . Content related to the sub clips 604a to 604d) may be synthesized in the first to third main trim media 602a to 602c.

The user may re-edit the contents of the sub clips 604a to 604d or adjust the temporal and spatial overlap with the main trim media 602a to 602c. As illustrated in FIG. 7D , this may be done by the user using an editing tool such as UIs 634 , 636 for arranging and resizing additional content 632 .

For example, when the additional content 632 is a still image or moving image obtained from another original media, the additional content 632 is a spatial part of the main trim media 630 according to a user's request, as illustrated in FIG. 7D . It may be arranged to overlap the area. That is, as illustrated in FIG. 7D , a plurality of original media may be overlapped and edited.

Also, according to the attribute of the additional content, the user may generate the sub-trimmed media by requesting trim for at least a part of the additional content, similar to the above-described trimmed media. The sub trim media may be identified through the sub clip of the clip display window 404 . The sub trim media may be a type of trim media similar to the main trim media 630 . In the present disclosure, for convenience of description, the sub-trim media may be mixed and described as trim media, sub-media, or sub-clip. The sub media and sub clips may be configured to include at least a portion of the original media. In addition, similar to the re-editing of the main trim media 630 , if the original media is maintained, the user may re-edit the primarily generated sub-trim media 632 . For example, the user checks the original media again and sub-trims by requesting a trim request to add a portion of the original media included in the firstly generated sub-trim media 632 or exclude a part of the included original media. Media 632 may be regenerated.

Specifically, the content element may include a media input menu 403a, a layer input menu 403b, an audio input menu 403c, an audio input menu 403d, a shooting menu 403e, and the like. The media input menu 403a, the layer input menu 403b, the audio input menu 403c, the voice input menu 403d, the shooting menu 403e, etc. may be a tool for decorating the mentioned content.

In the case of media and shooting, it may be a pre-stored or recorded image, video, etc. For Effects, Blur Effect, Mosaic Effect, Noise Effect, Sandstorm Effect, Melting Point Effect, Crystal Effect, Star Filter Effect, Display Board Effect, Haze Effect, Fisheye Lens Effect, Magnifying Glass Lens Effect, Flower Twist Effect, Night Vision Effect , a sketch effect, or the like. In addition, in the case of an overlay, it may be a sticker or an icon of various shapes or shapes, and in the case of a drawing, it may be a drawing object that can be created in a drawing area that is touch-inputted on an image display window. In the case of audio and voice, it may be a pre-stored audio file or a voice acquired from a microphone of the electronic device.

These elements can be produced as content by being arranged and combined in time and space. In addition, each element may be overlapped and arranged in a depth direction in the same time and two-dimensional space, and in this case, depth information between each element may be included. The arrangement and combination of the elements described above may be referred to as a relationship between elements of content in this specification.

When the storage and use setting of the backup media is requested in the image project (Y in S215 ), the processor 120 may store the trim media as the backup media.

The setting may be determined by a user's request or a basic setting of the editing application. The user's request may be determined by the basic information setting in step S115 of FIG. 3 or a separate request in the project currently being edited.

As an example, when trim media using only at least a portion of the original media is generated by the trim request, the processor 120 performs the generated trim media 1-1, 1-2, 2-, as illustrated in FIG. 8 . At least a portion of the first to third original media corresponding to 1, 3-1, and 3-2) may be stored as backup media. Here, the first to third original media may be content loaded by the user in the form of an initial clip on at least one of the main clip line 404a and the sub clip line 404b. Accordingly, the trim media 1-1, 1-2, 2-1, 3-1, and 3-2 of FIG. 8 may be at least one of the main and sub trim media.

The processor 120 manages a series of trim media 1-1, 1-2, 2-1, 3-1, and 3-2 edited by the user in a project, and each trim media 1-1, 1 -2, 2-1, 3-1, 3-2), a portion of the first to third original media corresponding to each trimmed media may be extracted, and the extracted original media may be stored as a backup image. The project and the backup image may be managed in separate areas of the memory 130 , for example, the public memory area 710 and the private memory area 720 . When the project is called in step S125 of Figure 3, the processor 120 through the video display window 401 and the clip display window 404, the main and sub media are synthesized edited content, main and sub clip lines (404a, 404b) can provide

The storage of the backup media will be described using a video as an example. When the middle time point of the video is trimmed as the starting point, the processor 120 processes the video so as to start from the closest I-Frame position before the start position requested by the user, The associated trim media may be stored as backup media. When extracting a part of the original video corresponding to the trim video, the processor 120 may extract a part of the original video by referring to the I-Frame related to the trim start point of the video.

As another example, the processor 120 may extract only the original media related to the main trim media, excluding the original media related to the sub trim media, and store the extracted media as the backup media. As described above, the sub trim media may be additional content trimmed in addition to the main trim media. Exclusion of the sub-trim media may be processed by a user's request or setting of an editing application, thereby reducing the resource burden of the memory 130 .

As another example, when the processor 120 receives a trim request instructing to generate all of the original media as trim media from the user, the processor 120 may store all of the original media as backup media. In this case, the original media may be related to at least one of the main and sub media.

The original media and the backup media are stored in the nonvolatile memory 130 as shown in FIG. 8 , but may be distributed and stored in memory areas having different properties. Specifically, as shown in FIG. 8 , the original media is stored in a removable memory area, for example, the public memory area 710 , and the backup media is a memory area different from the erasable memory area 310 so that it cannot be deleted without further manipulation by the user. , for example, may be stored in the private memory area 720 . The private memory area 720 may be, for example, a storage medium that manages a folder that is not exposed in a normal inquiry, a password, or the like, or manages a folder in another path that is intentionally accessed by the user.

In the present embodiment, the storage of the backup media may be stored in various ways or at different points in time. For example, the backup of the trim media may be executed at the time of adding the trim media to the project, or may be executed after checking the trim media requiring backup at the end of the project according to step S145 of FIG. 3 . As another example, the trim media may be backed up after checking the trim media that needs to be backed up at an interval of a predetermined time period, for example, 1 minute or 5 minutes, during project editing.

9 is a flowchart of an image editing method capable of performing a backup according to another exemplary embodiment of the present disclosure. FIG. 10 is a diagram illustrating an example of backing up trim media by performing the image editing method according to FIG. 9 . The process of FIG. 9 may be performed, for example, as detailed processes of steps S125 and S130 of FIG. 3 . In the present disclosure, the trim media is edited with only a part of the original media, and the trim media will be mainly described as main trim media.

First, the processor 120 may receive a user's request through an editing application, and call a pre-stored image project selected according to the request (S305).

Next, the processor 120 may check whether all of the corresponding original media for each trim media is stored in the public memory area 710 ( S310 ).

If all of the original media related to at least one of the trim media is not stored in the public memory area 710 and only the backup media for the trim media is stored only in the private memory area 720 (N of S310), the processor ( 120 ) may load the trim media based on the backup media into the clip setting area, for example, the clip display window 404 ( S315 ).

When the trim media is loaded, the processor 120 may provide the edited content in which the main and sub media are synthesized and the main and sub clip lines 404a and 404b through the image display window 401 and the clip display window 404 . . In addition, the processor 120 may provide various editing UIs for re-editing the edited content.

Meanwhile, taking the main trim media as an example, only the main trim media 602a to 602c stored as backup media may be loaded as a main clip in the main clip line 404a shown in FIGS. 4 and 7A . The processor 120 may control to inquire only the main trim media corresponding to the range of the backup media among the related original media through the main clip line 404a and/or the image display window 401 . This is because the original media including all ranges excluded from the main trim media are deleted from the public memory area 710 .

10 , when the first original media according to the trim media 1-1 and 1-2 according to the previous editing is deleted from the public memory area 710 , the trim media 1 among the first original media Only the backup media 1-1 and 1-2 corresponding to the ranges of -1 and 1-2) may be stored and managed in the private memory area 720 . Here, the range may be a trim range of the first original media according to at least one of a time interval and a spatial domain.

The processor 120 may load only the main clips corresponding to the range of the backup media 1-1 and 1-2 related to the trim media 1-1 and 1-2, for example, in the main clip line 404a. can The user can check other parts of the first original media not included in the trim media (1-1, 1-2) even if the window of main clips loaded as the backup media (1-1, 1-2) is expanded as much as possible. none.

Subsequently, the processor 120 may set the editing limit of the trim media loaded as the backup media as the backup media range ( S320 ).

Referring to FIG. 10 as an example, the processor 120 also shows the editing limits of the trim media 1-1 and 1-2 loaded in the main clip line 404a according to the confirmation range determined in step S315 as well as the backup media 1 It can be set in the range of -1, 1-2).

Subsequently, the processor 120 may change the editing of the trim media within the backup media range by receiving a request for changing the media editing by the user ( S325 ).

Referring to FIG. 10 as an example, the user may edit the trim media 1-1 and 1-2 to add another part of the first original media not included in the trim media 1-1 and 1-2. It is not possible, and only editing such as deletion and division within the trim media 1-1 and 1-2 can be performed. As illustrated in FIG. 10 , the user requests editing changes based on the backup media 1-1 and 1-2, and the processor 120 generates trimmed media derived from the backup media 1-1 and 1-2. (1-1-a, 1-1-b, 1-2-a).

Next, the electronic device may update and store the edited trim media as a backup media ( S330 ).

Taking the edited trim media 1-1-a as an example in FIG. 10 , the processor 120 performs the backup media corresponding to the edited trim media 1-1-a in the range of the previous backup media 1-1. (1-1-a) may be newly stored in the private memory area 720 . The detailed method of storage is substantially the same as that described with reference to FIG. 6 . The backup media 1-1 may be moved to the public memory area 710 according to a user's request or an application setting, for example, and managed as secondary original media. The secondary original media may be provided in preference to the backup media 1-1-a in subsequent editing changes to the trim media 1-1-a. In this case, the editing limit of the trim media 1-1-1 may be set to the range of the secondary original media. As another example, the backup media 1-1 may be provided as secondary original media in subsequent editing changes while continuing to be managed in the private memory area 720 . As another example, the backup media 1-1 is deleted, so that the trim media 1-1-a based on the backup media 1-1-a is loaded in a subsequent edit change, and the edit limit is also changed to the backup media 1 It can be set in the range of -1-a).

On the other hand, if all of the original media and the backup media related to at least one of the trim media are stored in the public memory area 710 and the private memory area 720 (N in S310), the processor 120 stores the original media The based trim media may be loaded into the clip setting area, for example, the clip display window 404 (S335).

The processor 120 takes precedence over the backup media 2-1, 3-1, 3-2 corresponding to the trim media 2-1, 3-1, 3-2, for example in the main clip line 404a. Thus, it is possible to load the main clips with the second and third original media including all parts including the trim media 2-1, 3-1, and 3-2. Accordingly, the user can expand the window of the main clips to check other parts of the second and third original media not included in the primary edited trim media 2-1, 3-1, 3-2. have.

Subsequently, the processor 120 may set the editable limit of the trim media to the range of the original media ( S340 ).

Referring to FIG. 10 as an example, the processor 120 is an editing limit diagram of the trim media 2-1, 3-1, and 3-2 loaded on the main clip line 404a according to the confirmation range determined in step S335. It can be set by extending the range of the second and third original media.

Subsequently, the processor 120 may receive a request to change the media editing by the user and change the trimmed media editing within the original media range ( S345 ).

Referring to FIG. 10 as an example, the user adds different parts of the second and third original media not included in the trim media 2-1, 3-1, 3-2, so that the trim media 2-1, 3-1, 3-2) can be edited, and also editing such as deletion and division can be performed within the trim media 2-1, 3-1, 3-2. As illustrated in FIG. 10 , the user requests editing changes based on the second and third original media, and the processor 120 determines the trim media 1-1-a, 1 derived from the second and third original media. -1-b, 1-2-a) can be produced.

Next, the processor 120 may update and store the edited trim media as the backup media according to the user's request (S330).

Referring to the modified trim media 2-2 in FIG. 10 as an example, the processor 120 newly stores the backup media 2-2 corresponding to the trim media 2-2 in the private memory area 720 . can The detailed method of storage is substantially the same as that described with reference to FIG. 6 . The previous backup media 2-1 does not match the edited and changed trim media 2-2, and thus may be deleted from the private memory area 720 . The second original media may not be deleted, and unless deleted, may be provided in preference to the backup media 2-2 in a subsequent edit change of the trim media 2-2. In this case, the editing limit of the trim media 2 - 2 may be set as the range of the second original media.

According to the present disclosure, even if the original media used for the edited video is deleted, the backup media can be stored and used in subsequent editing. In addition, by storing only at least a partial area of the original media used for the edited video as the backup media, it is possible to reduce the memory capacity required for the backup.

11 is a flowchart illustrating a process of deleting backup media.

After the backup media is stored, the processor 120 may receive a request to delete the image project (S405).

In the request to delete the video project, when the original media of the trim media is stored in the public memory area 710 (Y in S410), the processor 120 deletes all the trim media of the video project and all the corresponding backup media. , it is possible to maintain the storage of the original media associated with the trim media (S415).

On the other hand, if the original media of the trim media is not stored in the public memory area 710 (N in S410), the processor 120 may delete all the corresponding backup media together with all the trim media of the image project. There is (S420).

In an embodiment different from this embodiment, the processor 120 may receive a request to delete the trim media. In this case, the processor 120 may also delete the backup media corresponding to the trim media.
