1 to 7 , the photo correction method according to an embodiment of the present invention may refer to a method in which the server 10 receives a photo from the user's electronic device P and corrects the photo. have.

For example, the photo correction method may be implemented by the server 10 .

For example, the user's electronic device (P) may be a user's smart phone, tablet PC, desktop, etc., and may correspond to any configuration capable of delivering a photo to the server (10).

However, for convenience of explanation, it is assumed that the electronic device P of the user is a smart phone having a touch display.

For example, the photo correction method may include a photo acquisition step in which the server 10 acquires a plurality of photos from the electronic device P of the user.

For example, the server 10 may obtain a video file from the electronic device P, and the video file may include a plurality of photos.

For example, a moving picture may consist of 2 to 150 pictures (frames).

FIG. 2 is a schematic diagram for explaining a plurality of photos obtained by the server 10 from the electronic device P, and includes four photos that are first to fourth photos f1, f2, f3, and f4. was assumed to be.

As sequentially illustrated in FIGS. 2A to 2D , a plurality of photos constituting a moving picture may include a plurality of specific images.

As an example, it may include a human image E1 , a soccer ball image E2 , a basketball image E3 , and a background image E4 that is the Eiffel Tower.

As shown in FIG. 2 , when comparing the first to fourth photos f1 , f2 , f3 , and f4 with each other, the person image E1 and the background image E4 constituting the photo are a plurality of It is moved less than a preset distance from any one point within the frame, the soccer ball image E2 is moved more than a preset distance from the left to the right of the frame, and the basketball image E3 is the upper side of the frame. It is assumed that the movement moves downward by more than a preset distance.

The server 10 performs a human image E1, a soccer ball image E2, and a basketball on the first to fourth photos f1, f2, f3, and f4 through known RGB analysis, shape analysis, etc. The blank image E3 and the background image E4 can be distinguished from each other.

Here, as an example, the photo correction method may further include a reference photo specification step of specifying, by the server 10, a reference photo to be corrected among a plurality of photos.

The reference photo may mean a corrected photo that is finally transmitted to the electronic device P of the user among the first to fourth photos f1, f2, f3, and f4.

For example, the specification of the reference photo may be implemented while the user specifies any one of a plurality of photos through the electronic device P and transmits the information to the server 10 .

That is, the server 10 receives not only a plurality of photos from the electronic device P in the photo acquisition step but also information on the reference photo among the plurality of photos, and uses the photo corresponding to the information as the reference photo. may be specific.

For example, the reference photo may be specified as the first photo f1.

Here, as an example, the photo correction method may further include a correction object specifying step in which the server 10 specifies a correction object to be corrected among a plurality of objects constituting the reference photo.

To explain this in more detail, as shown in FIG. 3 , in the first photo f1 specified as the reference photo, a plurality of objects constituting the first photo f1, such as a person image E1, and a soccer ball There are an image E2, a basketball image E3, and a background image E4, and the server 10 has a human image E1, a soccer ball image E2, a basketball image E3, and a background image E4. ), a correctable region that can be the correction object may be specified and transmitted to the electronic device P.

That is, in the step of specifying the correction object, the server 10 may specify a correctable object on the reference photo and transmit it to the electronic device P of the user.

For example, when the server 10 compares the first to fourth photos f1, f2, f3, and f4 with each other, the soccer ball image E2 and the basketball image moved by a preset distance or more With respect to (E3), each correctable area (A1, A2) may be indicated by a dotted line or the like and transmitted to the electronic device (P).

The user selects the correctable area A1 for the soccer ball image E2 and the correctable area A2 for the basketball image E3 on the first photo f1 through the display of the electronic device P. It can be recognized, and if you want to delete only the soccer ball image E2, you can transmit the information to the server 10 by touching only the soccer ball image E2, and if you want to delete the soccer ball image E2, If E2) and the basketball image E3 are to be deleted, the information may be transmitted to the server 10 by touching the soccer ball image E2 and the basketball image E3.

In addition, as an example, specifying the correction object allows the user to use the electronic device P to obtain a person image E1, a soccer ball image E2, a basketball image E3 and It may be implemented by touching at least one of the background images E4 and transmitting the information to the server 10 .

Meanwhile, for convenience of explanation, it will be assumed that the correction object is a soccer ball image (E2) and a basketball image (E3).

Here, as an example, in the photo correction method, the server 10 deletes the correction object on the reference photo, extracts a composite object from another image, and synthesizes the composite object on the deleted correction object to correct it It may further include a corrected photo generation step of generating a photo.

As an example, as shown in Fig. 4(a), the server 10 deletes the soccer ball image E2 and the basketball image E3 that are the correction objects on the first photo f1, and the By extracting the composite object from the other image in place, it is possible to generate a corrected picture through synthesis.

Hereinafter, two embodiments of extracting the composite object from another image will be described.

For example, as shown in FIG. 4(b) , the server 10 synthesizes the photo from a photo other than the reference photo among a plurality of photos acquired from the electronic device P of the user through the photo acquisition step. object can be extracted.

That is, the other image may mean a picture other than the reference picture among a plurality of pictures acquired from the electronic device P of the user through the picture acquisition step.

For example, among the first to fourth photos f1, f2, f3, and f4, when the first photo f1 is the reference photo, the server 10 sends the first photo f1 For each region in which the soccer ball image E2 and the basketball image E3 are deleted, any one of the second to fourth photos f2, f3, and f4 is selected to be synthesized. object can be extracted.

As an example, the server 10 may select the second photo f2 as another image, and at this time, a soccer ball image E2 and a basketball image on the first photo f1 from a predetermined reference point ( The composite object to be synthesized may be extracted by selecting the regions A3 and A4 at the same position as the respective regions from which E3) has been deleted on the second photo f2, respectively.

After that, the server 10 compares the composite object extracted from the second photo f2 to each of the soccer ball image E2 and the basketball image E3 on the first photo f1 deleted. By synthesizing the region, the corrected photo can be generated.

Here, the criterion for the server 10 to select any one of the second to fourth photos f2, f3, and f4 as the other image is a non-deleted human image ( E1) and the background image E4 may be a photo having at least one of the most similar size, color, and clarity.

Meanwhile, another embodiment of extracting the composite object from another image will be described below.

For example, in the obtaining of the photo, the server 10 may further obtain location information for a plurality of photos from the electronic device P of the user.

That is, the server 10 may further acquire from the electronic device P not only a plurality of photos, but also the location information about a location where the photos were taken.

For example, the server 10 may know through the location information that the first photo f1 is a location taken near the Eiffel Tower.

Here, as an example, in the step of generating the corrected photo, the composite object may be extracted from a photo in which the location information satisfies a predetermined location criterion among a plurality of photos previously stored by the server 10 .

To explain this in more detail, as shown in FIG. 5( a ), the server 10 may have a fifth photo f5 near the Eiffel Tower and location information about it stored in advance in the memory unit 400 , and , as shown in FIG. 5(b), the server 10 may have another sixth photo f6 near the Eiffel Tower and location information about it stored in advance in the memory unit 400, as shown in FIG. As shown in (c), the server 10 may have the seventh photo f7 near the pyramid and its location information stored in advance in the memory unit 400, and the As described above, the server 10 may have the eighth photo f8 near the opera house stored in advance in the memory unit 400 and location information therefor.

The location information may include information about each unique longitude and latitude.

Here, the server 10 selects another image that is a photo having location information satisfying the predetermined location criterion based on location information of the first photo f1 that is the reference photo in the memory unit 400 . can

For example, the predetermined location reference may refer to a reference having location information within a predetermined distance based on location information of the first photo f1.

For example, the predetermined distance may be changed according to the number of photos selected as other images by the server 10 .

For example, when the number of selected other images is less than 5 when the predetermined distance is preset to 50 m, the server 10 may reset the predetermined distance to 100 m to increase the number of candidate groups of other images by an appropriate amount. .

As an example, the server 10 may be configured as a candidate group of other images based on the location information of the first photo f1 among a number of images stored in the memory unit 400 in FIGS. 5(a) and 5(b). The fifth photo f5 and the sixth photo f6 may be selected, and any one of the fifth photo f5 and the sixth photo f6 may be selected to determine the other image.

At this time, the server 10 removes the soccer ball image E2 and the basketball image E3 on the first photo f1 among the fifth photo f5 and the sixth photo f6, respectively. A photo having the most similar object may be selected based on the color, clarity, etc. of the surrounding area located within a predetermined distance from the .

As shown in FIG. 6 , the server 10 may select a sixth photo f6 as another image, and may extract the composite objects A3 and A4 from the sixth photo.

After that, the server 10 synthesizes the composite object on the first photo f1, and transmits the corrected photo to the electronic device P of the user with the completed corrected photo. steps can be implemented.

The server 10 for correcting a photo according to another embodiment of the present invention may be a device implementing the above-described photo correction method.

For example, the server 10 acquires a plurality of photos from the electronic device P of the user, specifies a reference photo to be corrected among the plurality of obtained photos, and is a correction target among a plurality of objects constituting the reference photo. Specifying a correction object, deleting the correction object on the reference photo, extracting a composite object from another image, synthesizing the composite object on the deleted correction object to generate a corrected photo, and the user's electronic device It is possible to transmit the corrected photo to (P).

For example, as shown in FIG. 7 , the server 10 may include a receiving unit 100 that receives predetermined data/information for implementing the photo correction method from the electronic device P, It may further include a memory unit 400 for storing predetermined data/information for implementing the photo correction method, and an input unit 500 for receiving data/information for implementing the photo correction method from an administrator can do.
