In the accompanying drawings, in order to more clearly express the technical idea of the present invention, parts that are inferior to the technical idea of the present invention or that can be easily derived from those skilled in the art are simplified or omitted.

As shown in FIGS. 1 to 7, a video editing method according to an embodiment of the present invention may be a method of editing a video (hereinafter, “editable video”) acquired from a user's electronic device P. .

For example, video editing may be implemented in the server 10.

As an example, the video editing method may include an editing target video acquisition step in which the server 10 obtains the editing target video from the user's electronic device P.

For example, the server 10 may obtain the editing target video from the electronic device P.

For example, the editing target video may include a plurality of frames.

For example, one video to be edited may consist of 2 to 150 frames.

FIG. 2 is a schematic diagram for explaining the editing target video, and it is assumed that the editing target video includes four frames, which are first to fourth frames f1, f2, f3, and f4.

As sequentially shown in FIGS. 2A to 2D, the plurality of frames constituting the editing target video may include a plurality of specific images.

For example, it may include a person image (E1), a soccer ball image (E2), a basketball image (E3).

As shown in FIG. 2, when comparing the first to fourth frames f1, f2, f3, and f4 with each other, the human image E1 constituting the editing target video is within the plurality of frames. Is moved to less than a preset distance from an arbitrary point in, the soccer ball image (E2) is moved from the left to the right of the frame more than the preset distance, and the basketball image (E3) is moved from the top to the bottom of the frame. It is assumed that it is moved beyond a preset distance.

In this case, the video editing method may further include an editing frame generation step of generating an edit frame by modifying an image constituting the frame based on a plurality of frames constituting the editing target video. have.

The edit frame may be generated by deleting, relocating, or combining images on a plurality of frames to be edited.

For example, in the generating of the editing frame, the editing frame may be generated by combining an image of one of the frames and an image of the other frame.

To explain this in more detail, as an example, in the editing frame generation step, a predetermined target image is deleted from the images constituting one of the frames, and a predetermined composite image among images constituting the other frame is The editing frame may be generated by compositing on an image.

For example, as shown in FIG. 3, FIG. 3 (a) may refer to the first frame f1, and FIG. 3 (b) may refer to the second frame f2.

Here, as an example, in the case of deleting the soccer ball image (E2) on the first frame (f1), which is the target image, the server 10 is the first frame (f1) on the second frame (f2). Selecting the composite image corresponding to the area A3 corresponding to the area A1 including the soccer ball image E2 above, and the area including the soccer ball image E2 on the first frame f1 ( A1) may be deleted, and the composite image area A3 on the second frame f2 may be combined on the first frame f1 in the deleted area A1.

As a result, in the first frame f1, the soccer ball image E2 on the first frame f1 is deleted, and the composite image on the second frame f2 without the soccer ball image E2 is formed. Can be.

Similarly, in the case of deleting the soccer ball image E2 on the second frame f2, which is the target image, the server 10 includes the soccer ball image E2 on the second frame f2. (A5) is deleted, and the composite image corresponding to the area A5 including the soccer ball image E2 on the second frame f2 is selected on the third frame f3, and The composite image on the third frame f3 may be synthesized on the second frame f2 in the deleted area A5 on the second frame f2.

As a result, the soccer ball image E2 may be deleted even on the second frame f2.

The method by which the server 10 can specify the target image for each frame may be implemented by calculating a relative change in RGB and/or CMYK in units of preset pixels on the frame.

A detailed description of this specific method will be omitted in that a person skilled in the art can clearly derive from the prior art.

The method by which the server 10 can specify the composite image for each frame is an arbitrary point within a plurality of the frames (for example, the center point of each frame or the center point of the human image E1) From, it may be calculated and specified as the same distance and the same area as the target image.

That is, the specification of the composite image is dependent on the specification of the target image, and when the target image is specified, the target image is calculated as the same distance and the same area as the target image from an arbitrary point in the frame, and may be dependently specified. .

However, the present invention is not limited thereto, and a method capable of easily changing a method for specifying the target image and the composite image from the standpoint of a person skilled in the art can be applied to the present invention.

For example, target selection information for selection of the target image to be deleted among a plurality of images constituting the frame may be obtained from the electronic device P.

That is, the video editing method may further include the step of obtaining, from the electronic device P, object selection information, in which the server 10 obtains object selection information regarding the target image specification.

For example, when the user wants to delete the soccer ball image E2 from the editing target video, the target for deleting the soccer ball image E2 through the electronic device P by selecting the soccer ball image E2 Selection information may be transmitted to the server 10.

Likewise, the target image is determined by the target selection information, and the composite image may be determined dependently by the target image by calculating the same distance and the same area as the target image from an arbitrary point in the frame.

In addition, as an example, the target image may be specified as an image that is moved over a predetermined distance on a plurality of the frames among images constituting the frame.

To explain this in more detail, as described above, the human image E1 is moved less than a preset distance on the plurality of frames, and the soccer ball image E2 and the basketball image E3 are recorded on the plurality of frames. As it moves more than a set distance, the server 10 calculates a plurality of images on the plurality of frames and a distance to which the images are moved, and moves a soccer ball image E2 that is moved more than a preset distance on the plurality of frames, and A basketball image (E3) (corresponding to the target image) is specified, the composite image is synthesized on each of the frames, and as a result, a soccer ball image (E2) and a basketball image (E3) are displayed on the editing target video. ) Can be deleted.

The preset distance described above may be set by a user and/or an administrator.

Here, as an example, the video editing method may include an editing frame transmission step in which the server 10 transmits the editing frame to the electronic device P.

For example, in the transmitting of the edit frame, the server 10 may transmit the edited frame edited by the electronic device P in a photo format or a video format including a plurality of the edit frames.

As a result, the user can view the edit frame through the electronic device P.

Here, as an example, in the video editing method, a feedback information acquisition step in which the server 10 obtains feedback information on the edit frame from the electronic device P, and the server 10 is based on the feedback information. The re-editing frame generation step of generating a re-editing frame by modifying the image of the edited frame may be further included.

To explain this in more detail, as shown in FIG. 4, on the editing frames f1 and f2 provided to the electronic device P, an area corresponding to the soccer ball image E2, that is, an area corresponding to the composite image There may be an afterimage (N) in (A1, A5).

This afterimage (N) may be generated by a difference in RGB and/or CMYK between the composite image and the surrounding image.

When such an afterimage (N) is generated, the user may transmit the feedback information for removing the afterimage (N) to the server 10 through the electronic device (P).

Here, when obtaining the feedback information, the server 10 deletes the composite image on the edit frame, and combines a recomposite image from among images constituting another frame onto the composite image You can create an edit frame.

To explain this in more detail, as shown in FIG. 4(a), assuming that an afterimage N exists on the composite image area A1 on the first frame f1, the server 10 When acquiring the feedback information, deletes the composite image region A1 on the first frame f1, and corresponds to the composite image region A1 on the second frame f2 in FIG. 4B. Selecting the recomposite image in the region A6 or in the region corresponding to the composite image region A1 on the third frame f3 and/or the fourth frame f4 although not shown in the drawing, The re-edited frame may be generated by recombining the selected recombination image area A6 to the deleted area A1 on the first frame f1.

In this case, for example, when the server 10 obtains the feedback information, the size of the composite image region to be deleted may be larger than the region of the composite image synthesized in the editing frame generation step.

For example, the range of the composite image deleted in the reediting frame generating step may be within a preset distance from the target image deleted in the editing frame generating step.

Here, as an example, the recomposite image synthesized in the reediting frame generation step may be the same as or larger than the deleted composite image.

As a result, the specification of the composite image deleted in the re-editing frame generation step is dependently implemented by specifying the target image deleted in the editing frame generation step, and the re-composition synthesized in the re-editing frame generation step Image specification may be implemented dependently by specifying the deleted composite image.

In this way, by the step of generating the reediting frame, the reediting frame may have a clean image from which the afterimage (N) has been removed.

In the following, another example of editing the editing target video will be described with reference to FIGS. 5 and 6.

Parts overlapping with the video editing method described above will be briefly described or omitted in order to more clearly describe the technical idea of the present invention.

As shown in FIG. 5, the editing target video may include two frames, which are a first frame f1 and a second frame f2.

5(a) shows the first frame f1, which includes an image H1 of a woman with eyes closed and an image H2 of a man with eyes open on the first frame f1. I can.

5(b) shows the second frame f2, which includes an image H1 of a woman with eyes open and an image H2 of a man with eyes closed on the second frame f2. I can.

At this time, the user may want to acquire a frame in which both men and women have their eyes open.

To implement this, in the video editing method, the server 10 may obtain the editing target video through the editing target video acquisition step.

In this case, the video editing method may further include the step of obtaining, from the electronic device P, synthesis selection information, in which the server 10 obtains synthesis selection information regarding the synthesis image specification.

That is, the synthesis selection information may be specified as the area A7 of the woman's face with the eyes open on the second frame f2 through the electronic device P of the user, and the server 10 The synthesis selection information can be obtained from (P).

In this case, the server 10 may specify the composite image, which is the female face image A7 with eyes opened on the second frame f2, based on the composite selection information.

In addition, the video editing method may further include a frame selection information acquisition step of acquiring frame selection information on which frame the composite image is to be synthesized from the electronic device P.

That is, the server 10 may synthesize the composite image on a frame selected based on the frame selection information on which frame to combine the composite image.

To explain this in more detail, the image A7 of the woman's face with the eyes open on the second frame f2 of FIG. 5(b) is the synthesis selection information, and the first frame f1 of FIG. 5(a) ) Is the frame selection information, the server 10 specifies the composite image, which is the image A7 of the woman's face with the eyes open on the second frame f2, and the specified image of the woman's face and By specifying the target image, which is the image A8 of the woman's face on the corresponding first frame f1, deleting the target image on the first frame f1, and deleting the target image on the specified second frame f2 The composite image is synthesized with the target image on the deleted first frame f1, and as a result, the editing frame including the female face image A7 with eyes open on the first frame f1 is generated. I can.

The composite image is determined by the composite selection information, but the target image may be determined by the server 10 as an image identical to the frame selection information and RGB and/or CMYK of the composite image.

That is, the composite image may be determined by the composite selection information, and the target image may be determined by the composite image.

FIG. 6 shows that the edited frame is generated by the video editing method. As shown in FIG. 6(a), when the first frame f1 is the frame selection information, FIG. 5(b) If the image A7 of the woman's face with eyes opened is specified as the composite image, the server 10 may specify the target image A8, which is an image corresponding to the composite image.

Thereafter, as shown in FIG. 6(b), the server 10 deletes the target image A8 on the first frame f1, and synthesizes the composite image A7 thereon. As a result, the editing frame in which both men and women open their eyes may be generated on the first frame f1.

In addition, as an example, in the video editing method, when the frame constituting the editing target video is blurred due to hand shaking, the server 10 corrects the frame to black and white, and then the black and white value is the largest value (the darkest Value), the remaining parts can be corrected.

In addition, as an example, when deleting the target image and combining the composite image on the spot, when the ratio of the target image and the ratio of the composite image are different, the server 10 determines the ratio of the target image. It is also possible to adjust the ratio of the composite image as a basis.

The video editing server 10 according to another embodiment of the present invention may be a device implementing the video editing method described above.

As an example, as shown in FIG. 7, the video editing server 10 includes a receiving unit 100 that obtains data including an edit target video from the user's electronic device P, and a plurality of A control unit 200 for generating an edited frame by modifying an image constituting the frame based on the frame, and a transmission unit 300 for transmitting the edited frame to the electronic device P.
