There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, an image editing apparatus 100 according to an exemplary embodiment of the present invention includes a display unit 110, a storage unit 120, a camera 130, and an editing interface providing unit 140. The image editing interface provided to the image editing apparatus 100 may be mounted on a digital camera, a mobile communication terminal, a smartphone, a tablet computer, or the like. Preferably, when a specific application is installed, the image editing interface may be mounted on the corresponding apparatus. .

The display unit 110 is a display means for displaying various information processed by the image editing apparatus 100, and may be used by liquid crystal display (LCD) technology, light emitting polymer display (LPD) technology, or light emitting diode (LED) technology. Can be. In addition, the display unit 110 may be a touch display such as a resistive type or an infrared type. When the display unit 110 is a touch display, an output interface and an input interface are provided to the user.

The storage unit 120 is a storage means for storing data necessary for image editing. The storage unit 120 stores an image file and stores various special effect data necessary for image synthesis. For example, the storage unit 120 stores data related to various special effects such as data about a special effect in which light shines, data about a special effect disappearing as the text is reduced, and data about a special effect disappearing as the text is enlarged. . In addition, the storage unit 120 stores the editing result data obtained by synthesizing the image and the special effect. The storage unit 120 may include high speed random access memory, and may also include one or more magnetic disk storage devices, nonvolatile memory such as flash memory devices, or other nonvolatile semiconductor memory devices.

The camera 130 has a lens to capture a peripheral image through the lens.

The editing interface providing unit 140 generates a user interface related to image editing and displays the display on the display unit 110. In detail, when the user wants to edit a specific image, the editing interface providing unit 140 generates an image editing interface including the image and an editing tool for editing the image and outputs the image editing interface to the display unit 110. In addition, the editing interface providing unit 140 synthesizes the image to be edited with the special effect selected by the user, and stores the edited result data thus synthesized in the storage 120.

Meanwhile, the editing interface providing unit 140 includes a timeline adjusting module 141 for adjusting the timeline.

The timeline adjusting module 141 extends the timeline length of the video to be edited according to the timeline length of the editing section. In detail, the timeline adjusting module 141 checks an edit section designated by a user among all playback sections of the image, checks whether the timeline length of the edit section is less than a preset threshold length, and if less, Increase the length of the timeline. In addition, when the user selects a control icon located at the end of the editing section in order to adjust the end time of the editing section, the timeline adjusting module 141 has a minimum length of timeline in which the editing section can be shortened to a minimum. Determine whether it is less than the threshold length, and if the timeline minimum length is less than the threshold length, lengthen the length of the timeline so that the timeline minimum length is greater than or equal to the threshold distance.

Hereinafter, a method of adjusting a timeline for convenience of image editing in the image editing apparatus 100 will be described in more detail with reference to FIGS. 2 to 6.

Referring to FIG. 2, when an image to be edited is selected by a user, the editing interface providing unit 140 displays the image editing interface including the video and the editing tool on the display 110 (S201). The image to be edited may be an image that is already stored in the storage 120 or an image that is temporarily stored by real-time shooting through the camera 130.

Referring to FIG. 3, the editing interface providing unit 140 includes a video selected by the user for editing, a timeline 22 representing a playback time of the video, a playback control bar 23, a playback button 21, and various special effects. The image editing interface including the

editing tools

24a, 24b, and 24c capable of synthesizing the same is displayed on the display unit 110. The playback control bar 23 is a graphic element representing a playback time point that is currently playing. When the user changes the position of the playback control bar 23 on the timeline 22, the playback control bar 23 is located. The video from the time of reproduction is output. In addition, among the special effects tools of FIG. 3, the star-shaped special effects tool 24a is an editing tool used to synthesize a halo effect for emphasizing a specific object, that is, an effect of shining light at the position of the specific object. In addition, reference numeral 24b of FIG. 3 is a tool used to process computer graphics of a specific object, and reference numeral 24c is an editing tool used to synthesize text input by a user (or text registered in advance) with an image. Each special effect has a minimum duration (eg, 0.5 seconds) and also has a default duration (eg, 2 seconds).

Referring back to FIG. 2, the image editing interface providing unit 140 receives selection information on any one of a plurality of editing tools listed in the image editing interface from the user (S203).

Then, the image editing interface providing unit 140 checks a special effect output according to the selected editing tool by the user, outputs a sample image of the special effect on the screen, and receives a position from which the special effect is output from the user. (S205).

In addition, the image editing interface providing unit 140 receives, from the user, information about a reproduction section in which the special effect is expressed among the reproduction sections of the entire image, and confirms that the reproduction section in which the special effect is expressed is an edit section ( S207). That is, the image editing interface providing unit 140 receives a playback section from which a special effect is expressed among all playback sections of an image, and sets the received playback section as an editing section.

Referring to FIG. 4, a special effect is located on a face of a person in the image editing interface. In other words, the user may move the position of the sample image 25 related to the special effect by touching and dragging the position on the face. The special effect of FIG. 4 illustrates the halo effect of light shining. In addition, the video editing interface of FIG. 4 sets a playback section in which the special effect is expressed according to a user's manipulation. In this case, the video editing interface may set a point at which video playback is paused, that is, a point where the playback control bar 23 is located as a start point at which a special effect is displayed, and set a default playback time of the special effect at the start point. You can set the added point as the end point at which the effect ends. For example, the video editing interface providing unit 140 sets the edit section to 1 minute 00 seconds when the playback time at which the halo effect with the default playback time of 2 seconds starts is 1 minute 00 seconds in the video having the total playback time of 2 minutes. To 1 minute 02 seconds. In the video editing interface of FIG. 4, each of the start point control icon 26a and the end point control icon 26b located on the timeline 22 represents a start point and an end point at which a special effect is played, respectively, and the start point control icon 26a. And a playback section corresponding to the timeline between the endpoint control icon 26a is set as the editing section.

Meanwhile, when the position of the start point control icon 26a is changed by the user, the image editing interface providing unit 140 changes the start point position at which the special effect is displayed. That is, when the user changes the position of the start point control icon 26a on the timeline 22 by dragging, the image editing interface providing unit 140 changes the time point at which the special effect is expressed among the entire playback time of the image. do. In this case, the image editing interface providing unit 140 changes the position of the end point control icon 26b by the position where the start point control icon 26a is moved. That is, when the user changes the position of the start point control icon 26a on the timeline 22, the position of the end point control icon 26b is also changed by the position of the start point control icon 26a.

In addition, when the position of the endpoint control icon 26b is changed by the user, the image editing interface providing unit 140 shortens or extends the playback time of the special effect (that is, the duration of the special effect) in proportion to the position. . In other words, when the user moves the position of the endpoint control icon 26b to the right, the image editing interface providing unit 140 extends the playback time of the special effect in proportion to the moved distance, and the user controls the endpoint control icon ( Moving the position of 26b) to the left shortens the playing time of the special effect by the moved distance. In this case, when the endpoint control icon 26b is dragged to the left, the image editing interface providing unit 140 may display a minimum playback time (eg, 0.5) of a special effect shortened according to the movement of the endpoint control icon 26b. The position of the end point control icon 26b is controlled so as not to move to a position below the second).

In this state in which the editing section is set, the timeline adjusting module 141 checks the timeline length D1 of the editing section (S209), and the timeline length D1 of the checked editing section is less than a preset threshold length. It is determined whether or not (S211). In this case, the timeline adjusting module 141 may check the timeline length of the editing section based on the pixel coordinates. That is, the timeline adjustment module 141 uses the pixel coordinates of the start point (ie, the start point control icon) of the editing section and the pixel coordinates of the end point (ie, the end point control icon) to adjust the timeline length D1. You can check it.

Next, if the timeline length D1 of the checked editing section is less than the threshold length, the timeline adjusting module 141 may determine that the timeline length D1 of the editing section is equal to or greater than the threshold length. The length of the line 22 is increased (S213). That is, if the timeline length D1 of the editing section is less than the threshold length, the timeline adjusting module 141 may open an image such that the interval between the starting point control icon 26a and the ending point control icon 26b of the editing section is widened. Increase the overall timeline length. In other words, the timeline adjusting module 141 extends the timeline 22 of the image so that the pixel range of the editing section occupied on the editing screen is enlarged. In other words, if the timeline length D1 of the checked editing section is less than the threshold length, the timeline adjusting module 141 stretches and pulls the timeline 22 from side to side, and surrounds the editing section among the extended time sections. Some timeline that is not located on the screen hides. Accordingly, the user can precisely edit the image synthesizing effect for the corresponding playback point by accurately touching or clicking a specific playback point included in the editing section when editing the video.

On the other hand, when the timeline adjusting module 141 increases the timeline 22 of the image, the timeline of the image is thinned in proportion to the length of the image and is output to the image editing interface, thereby allowing the user to increase the timeline. Recognize that you lost.

FIG. 5 is a diagram illustrating an image editing interface having a longer timeline according to an embodiment of the present invention, wherein the length D2 of the editing section in the image editing interface of FIG. 5 is the length of the editing section of the image editing interface of FIG. It can be seen that the increase compared to D1). Also, as the length of the timeline 22 increases, the timeline 22 thickness T2 of the video editing interface of FIG. 5 is made thinner than the timeline 22 thickness T1 of the video editing interface of FIG. 4. do.

Meanwhile, the image editing interface providing unit 140 may receive a selection of an endpoint control icon 26b corresponding to an end point of the editing section on the image editing interface (S215). That is, the image editing interface providing unit 140 may receive a touch input signal of the endpoint control icon 26b corresponding to the end point of the editing section from the user who wants to reset the reproduction length of the editing section.

Then, the timeline adjustment module 141 determines whether the minimum timeline length that can shorten the timeline of the editing section is less than the threshold distance (S217). That is, the timeline adjusting module 141 checks the minimum playing time of the special effect selected by the user, checks the minimum length of the timeline corresponding to the minimum playing time, and then determines whether the minimum length of the timeline is less than the threshold distance. Determine whether or not.

Next, if the timeline minimum length is less than the threshold distance, the timeline adjustment module 141 extends the timeline 22 of the image so that the timeline minimum length is equal to or greater than the threshold length (S219). . That is, the timeline adjustment module 141 extends the length of the video timeline from side to side so that the user can accurately touch or click a specific playback time included in the editing section, and thus the start point control icon 26a and the end point of the editing section. Allow the gap between control icons 26b to widen. In addition, when the timeline 22 of the image is extended, the timeline adjusting module 141 thins the timeline thickness of the image in proportion to the stretched length and outputs it to the display unit 110 so that the user has a long timeline. Recognize that you lost.

FIG. 6 is a diagram illustrating an image editing interface in which a timeline is elongated according to a user's touch input according to an embodiment of the present invention. In the image editing interface of FIG. 6, a length D3 of an editing section is illustrated in FIG. 5. Compared with the editing section length D2 of the interface, the minimum timeline length D4 that can be shortened also increases, particularly in the video editing interface of FIG. 6. Also, as the length of the timeline 22 increases, the timeline thickness T3 of the video editing interface of FIG. 6 is adjusted to be thinner than the timeline 22 thickness T2 of the video editing interface of FIG. 5.

Next, when the user edits the image, the image editing interface providing unit 140 checks the special effect, the special effect position, and the special effect playback section selected by the user, and the playback section of the original video corresponding to the editing section. A special effect is synthesized (S221). Subsequently, the image editing interface providing unit 140 stores the editing result data in which the original image and the special effect are synthesized in the storage 120 (S223). In this case, the image editing interface providing unit 140 may synthesize the original image and the special effect into a single image, and include a kind of special effect, location information (for example, screen coordinate information) and a special effect for which the special effect is expressed. Edit-related data in which a playback section is recorded may be generated, and the edit-related data may be stored in the storage 120 in place of the synthesized video.

As described above, in the image editing apparatus 100 according to the present invention, when a user edits an image, a gap between two control icons representing a start point and an end point of an editing section is narrow or two control icons overlap. By increasing the editing section of the image based on the timeline length of the editing section, the user is provided with convenience for editing the image, in particular, editing of the specific playback section. In addition, the image editing apparatus 100 according to the present invention intuitively recognizes the phenomenon in which the timeline increases by expressing the thickness of the timeline thinly in proportion to the length of the stretched timeline.
