Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time line adjustment method and a video editing apparatus,

The present invention relates to a video editing interface technology, and more particularly, to a time line adjusting method and an image editing apparatus for adjusting a time line of an image editing section to facilitate image editing.

As the demand and supply of imaging devices increases, most users have more than one device that can capture and edit images. Particularly, since a smart phone equipped with a video shooting and editing function is explosively spread, users shoot images using a smart phone, and then edit the photographed images. The following patent document discloses a method and system for providing a video data editing function to a mobile communication terminal.

However, the conventional image editing technology using the mobile communication terminal does not consider the progress of the image editing through a relatively small screen, which is inconvenient for the user to use. In addition, in the image editing interface implemented in the conventional mobile communication terminal, the time line corresponding to the editing section is formed to be too small, which makes it difficult for the user to select a specific point in the editing section. Particularly, when the reproduction time of the video to be edited is long and the section edited in the image is short, the interval between the two control icons indicating the beginning and end of the editing section becomes too narrow in the conventional image editing interface , Thereby making it difficult for the user to control the edit section.

The image to be edited may be an image already stored in the storage unit 120 or an image captured in real time through the camera 130 and temporarily stored.

3 is a diagram illustrating an image editing interface according to an embodiment of the present invention.

3, the editing interface providing unit 140 includes a video selected by the user for editing, a time line 22 indicating the playing time of the video, a playback control bar 23, a playback button 21, On the display unit 110, an image editing interface including editing tools 24a, 24b, When the user changes the position of the playback control bar 23 on the time line 22, the playback control bar 23 is positioned at a position where the playback control bar 23 is located An image from the reproduction time point is outputted. 3, the star-shaped special effect tool 24a is an editing tool used for synthesizing a halo effect for emphasizing a specific object, that is, an effect of shining light at a position of a specific object. In addition, reference numeral 24b in Fig. 3 is a tool used for processing computer graphics of a specific object, and reference numeral 24c is an editing tool used for synthesizing text entered by a user (or text registered in advance) with an image. Each of the special effects has a minimum playback time (e.g., 0.5 seconds) and also has a default playback time (e.g., 2 seconds).

Referring again to FIG. 2, the image editing interface providing unit 140 receives selection information of a tool from among a plurality of editing tools listed in the image editing interface (S203).

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

Then, the image editing interface providing unit 140 receives information on the playback section in which the special effect is displayed from the user, and confirms that the playback section in which the special effect is displayed is the edit section S207). That is, the image editing interface providing unit 140 sets, as an editing section, a reproduction section in which the special effect is displayed, out of all the reproduction sections of the image.

FIG. 4 is a diagram illustrating a state in which a display position and a playback interval of a special effect are designated in an image editing interface according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in the image editing interface, the special effect is located on the face of a person. In addition, the user can move the position of the sample image 25 associated with the special effect through the touch drag and place it on the face. The special effect of FIG. 4 illustrates a halo effect in which the light shines. In addition, the image editing interface of Fig. 4 sets a playback section in which the special effect is displayed according to the user's operation. At this time, the image editing interface can set the point at which the image reproduction is temporarily stopped, that is, the point where the reproduction control bar 23 is located, as the starting point at which the special effect is displayed, and also the default reproduction time of the special effect The added point can be set as the end point at which the special effect ends. For example, in the image having the total reproduction time of 2 minutes, if the reproduction time at which the backlight effect having the default reproduction time of 2 seconds starts is 1 minute and 00 seconds, To 1 minute 02 seconds. Each of the start point control icon 26a and the end point control icon 26b located on the time line 22 in the image editing interface of FIG. 4 represents a start point and an end point, respectively, And the end point control icon 26a is the edit section.

On the other hand, when the position of the start point control icon 26a is changed by the user, the image edit interface providing unit 140 changes the start point position where the special effect is displayed. That is, when the user changes the position of the start point control icon 26a on the time line 22 through dragging, the image edit interface providing unit 140 changes the time point at which the special effect is displayed, do. At this time, the image editing interface provider 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 time line 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 end point control icon 26b is changed by the user, the image editing interface providing unit 140 shortens or extends the playing time of the special effect (i.e., duration of the special effect) in proportion to the position . The image editing interface providing unit 140 may extend the playing time of the special effect in proportion to the moved distance by moving the position of the end point control icon 26b to the right, 26b are shifted to the left, the reproduction time of the special effect is shortened by the moved distance. At this time, if the image editing interface providing unit 140 is dragged to the left of the end point control icon 26b, the end point control icon 26b is moved to a position corresponding to less than a minimum playing time (for example, 0.5 second) ) Of the end point control icon 26b.

In this state, the time line adjustment module 141 checks the time line length D1 of the edit section (S209). If the time line length D1 of the edit section is less than the preset threshold length (S211). At this time, the time line adjustment module 141 can check the time line length of the edit section based on the pixel coordinates. That is, the time line adjustment module 141 calculates the time line length D1 by using the pixel coordinates of the start point of the edit section (i.e., the start point control icon) and the pixel coordinates of the end point (i.e., the end point control icon) Can be confirmed.

Next, the time line adjustment module 141 determines whether the time line length D1 of the edit section is equal to or greater than the critical length, if the time line length D1 of the edit section is less than the critical length, The length of the line 22 is increased (S213). That is, if the time line length D1 of the edit section is less than the threshold length, the time line adjustment module 141 sets the start point control icon 26a and the end point control icon 26b Increase the total timeline length. Further, the time line adjustment module 141 extends the time line 22 of the image so that the pixel range occupied on the edit screen by the edit section is enlarged. If the time line length D1 of the editing section is less than the critical length, the time line adjustment module 141 may extend and extend the time line 22 to the left and right, Some timelines that are not located on the screen are hidden from the screen. Accordingly, the user can precisely edit the image synthesis effect on the reproduction point by touching or clicking the specific reproduction point included in the editing section precisely at the time of image editing.

On the other hand, when the time line adjustment module 141 enlarges the time line 22 of the image, the time line thickness of the image is reduced in proportion to the increased length and outputted to the image editing interface, To be recognized.

FIG. 5 is a diagram illustrating an image editing interface having a long time line according to an embodiment of the present invention. The length D2 of the editing section in the image editing interface of FIG. 5 corresponds to the length of the editing section of the image editing interface D1). As the length of the time line 22 increases, the thickness T2 of the time line 22 of the video editing interface of Fig. 5 is formed to be thinner than the thickness T1 of the time line 22 of the video editing interface of Fig. do.

On the other hand, the image editing interface provider 140 can select the end point control icon 26b corresponding to the end point of the editing section on the image editing interface (S215). That is, the image editing interface providing unit 140 can receive the touch input signal of the end point control icon 26b corresponding to the end point of the editing section from the user who desires to reset the reproduction length of the editing section.

Then, the timeline adjustment module 141 determines whether the minimum length of the timeline capable of minimizing the timeline of the editing section is less than the threshold distance (S217). That is, the timeline adjustment module 141 checks the minimum playback time of the special effect selected by the user, determines the minimum length of the timeline corresponding to the minimum playback time, and then determines whether the minimum length of the timeline is less than the threshold distance .

Next, the timeline adjustment module 141 extends the timeline 22 of the image so that the minimum length of the timeline equals or exceeds the threshold length if the minimum length of the timeline is less than the threshold distance (S219) . That is, the timeline adjustment module 141 extends the length of the video timeline to the left and right so that the user can precisely touch or click a specific playback point included in the edit section, and controls the start point control icon 26a and the end point The control icons 26b are spaced apart from each other. When the time line 22 of the image is increased, the time line adjustment module 141 outputs a thinning time line thickness of the image to the display unit 110 in proportion to the elongated length, To be recognized.

FIG. 6 is a diagram illustrating an image editing interface in which a time line is extended according to a user's touch input according to an embodiment of the present invention. The length D3 of the editing section in the image editing interface of FIG. The length of the editing interval D2 of the interface increases. In particular, the minimum time line length D4 that can be shortened in the video editing interface of FIG. 6 also increases. Further, as the length of the time line 22 increases, the time line thickness T3 of the video editing interface of Fig. 6 is adjusted to be thinner than the thickness T2 of the time line 22 of the video editing interface of Fig.

Next, the image editing interface providing unit 140 confirms the special effect, the special effect position, and the special effect playback period selected by the user when the user finishes editing the image, The special effects are synthesized (S221). Then, the image editing interface providing unit 140 stores the editing result data obtained by combining the original image and the special effect in the storage unit 120 (S223). At this time, the image editing interface providing unit 140 may synthesize the original image and the special effect into one image, and may include special effect types, location information (e.g., screen coordinate information) It is also possible to generate editing-related data in which the reproduction interval is recorded, and store the editing-related data in the storage unit 120 instead of the synthesized video.

As described above, in the image editing apparatus 100 according to the present invention, when a user performs image editing, the interval between two control icons indicating the start point and the ending point of the edit section is narrow or the two control icons overlap each other The editing section of the video is extended based on the time line length of the editing section so as to prevent the user from editing the video. In addition, the image editing apparatus 100 according to the present invention intuitively recognizes the phenomenon that the timeline extends when the timeline extends, by thinning the thickness of the timeline in proportion to the length of the timeline.
