The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

Hereinafter, an image sharing system and an image sharing method using the same according to embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a view showing the configuration of a photo taking and image sharing system using a mobile image segmentation according to an embodiment of the present invention, Figure 2 is a flow chart illustrating a photo taking and image sharing method using the photo taking and image sharing system. to be.

As shown in FIG. 1, the photo taking and image sharing system 100 using the mobile image segmentation according to an exemplary embodiment of the present invention includes a first user terminal 102, an image segmentation server 104, and a second user terminal ( 106 and an image sharing server 108, the respective components being connected to each other via a network 110. In this case, the network 110 refers to a wired network such as a local area network (LAN), a wired internet network, or a wireless network such as a wireless LAN (WiFi) or a mobile communication network.

In addition, the photographing and image sharing method using the mobile image segmentation according to an embodiment of the present invention, the image sharing method is largely the image registration step (S20), image purchase step (S21), shooting step (S22) and sharing step (S23) It includes.

Looking at the function of each block of the image sharing system 10 configured as described above are as follows.

The first user terminal 102 requests the image segmentation server 104 to generate a composition target image to be used for image synthesis using the previously stored original image, and registers the generated synthesis target image to the image sharing server 108. do. That is, the first user terminal 102 is a terminal that generates a synthesis target image and provides it to the image sharing server 108. In this case, the original image may be an image photographed using a camera module included in the first user terminal 102 or an image stored by the user in the first user terminal 102. For example, a user of the first user terminal 102 (hereinafter referred to as “first user”) may be connected to the first user terminal 102 or a device such as a digital camera that may be connected to the first user terminal 102. Taking a picture of yourself or a family and the like and extracting only the own image excluding the background from the taken picture and register it as the composition target image to the image sharing server 108.

Such a first user terminal may be formed of, for example, a PC or a mobile communication terminal.

The PC may be provided with a module having a camera function internally or connected to a digital camera to receive an image from the PC. It communicates with the image segmentation server 104 and the image sharing server 108 via a network. Also, the mobile communication terminal is a wireless terminal having a camera function therein, and communicates with the image segmentation server 104 and the image sharing server 108 through a wireless network such as 3G or WiFi. For example, mobile communication terminals include mobile phones, smartphones, tablet PCs, PDAs, and the like. The user may generate a synthesis target image from the original image through a wired terminal such as a PC or a wireless terminal such as a mobile communication terminal, and register it with the image sharing server 108.

The image segmentation server 104 extracts a composition target image from the original image through communication with the first user terminal 104 and transmits the composition target image to the first user terminal 102. In detail, the image segmentation server 104 receives the original image and selection area information inside the original image from the first user terminal 102, extracts a subject existing in the selection area from the background, and extracts the first image. Send to the user terminal. In addition, the image segmentation server 104 receives a boundary correction request for the subject extracted from the first user terminal 104 from the first user terminal 102, corrects the boundary of the subject according to the correction request, The corrected subject is transmitted to the first user terminal 102 as a composition target image.

Referring to FIGS. 2 and 3, a process of extracting a synthesis target image from the image segmentation server 104 is as follows.

First, the user of the first user terminal 102, that is, the first user selects one of the original images stored in the first user terminal 102, and the first user terminal 102 displays it on the screen. (S200 and the first picture of Figure 3).

Next, the first user designates a selection area of a box shape in the original image that is loaded to include the composition target image to be extracted (S201 and the second picture of FIG. 3). In the example shown in FIG. 3, since the synthesis target image to be extracted is the whole body picture 31 of the child, the second region of FIG. 3 includes the selection area 32 such that the whole body picture 31 of the child is included. Can be specified.

When the selection area is designated as described above, the first user terminal 102 transmits the original image and the selection area information to the image segmentation server 104, and the image segmentation server 104 recognizes a subject located inside the selection area. Then, by separating the subject 31 and the background image 30 by tracking the boundary of the subject, only the subject is extracted from the original image (first operation). In this case, the first operation may be performed using, for example, a grabcut algorithm. However, the Grabcut algorithm utilized in the embodiment of the present invention is just one embodiment, and it is also possible to use another algorithm among a plurality of algorithms that provide a function of extracting some images by tracking the boundary of the image and correcting the boundary. Do.

When the first operation is completed, the image segmentation server 104 transmits the extracted subject 31 to the first user terminal 102. Thereafter, the first user checks the subject 31 displayed on the first user terminal 102, and if necessary, corrects the boundary surface (S202 and the third picture of FIG. 3). Depending on the original image and the type of the subject or background to be extracted, there may be a case where the boundary of the subject is not separated from the background correctly and the background remains or a part of the subject is cut off even after performing the first operation. Therefore, in this case, the first user may designate an incorrect boundary by looking at the displayed result of the first operation and the boundary is not smooth or by dragging the wrong portion with a mouse or a finger touch. When the correction request for the wrong boundary is designated as the mouse drag or finger touch, the first user terminal 102 transmits the request to the image segmentation server 104, and the image segmentation server 104 selects the selected boundary. Is corrected through a quadratic operation using an algorithm such as Grabcut, and the corrected subject 31 is transmitted to the first user terminal 102. In this way, the corrected subject becomes a composition target image in the present invention, which is registered in the image sharing server 108 through the following process.

That is, the first user terminal 102 checks the image to be synthesized, and related text (image introduction, additional description, or title, etc.), the price of the image to be synthesized, and the donation ratio when the image to be synthesized is sold ( In other words, the ratio of the amount of money sold to charity when donating the image is set (S203), and after inputting payment information such as account information of the person who uploaded the image to be synthesized (S204, This step may be omitted if payment information has already been registered), and the information related to the image is registered in the image sharing server 108 (S205).

The second user terminal 106 is a terminal that downloads and stores a synthesis target image registered and stored in the image sharing server 208 and generates a composite picture therefrom. Like the first user terminal 106, the second user terminal 106 may also be a PC or a mobile communication terminal having a photographing function. That is, in the present invention, the classification of the first user terminal 102 and the second user terminal 106 is functional, and when the same terminal is used to generate a composition target image as needed, the first user terminal 102 is used. Note that it may function as the second user terminal 106, and when used to take a composite picture using the composition target image.

The second user terminal 106 receives the synthesis target image registered in the image sharing server 108 from the image sharing server 108, and captures a composite picture including at least a portion of the transmitted synthesis target image. The registered picture is registered in the image sharing server 108 to be shared with other users. On the other hand, the photo synthesis in the second user terminal 106 is performed at the same time when taking a picture using the second user terminal 106, a detailed description thereof will be described later.

The image sharing server 108 receives and stores the synthesis target image from the first user terminal 102, and stores the synthesis target image stored at the request of the second user terminal 106 to the second user terminal 106. It transmits and receives and stores the composite picture taken by the second user terminal to be shared with other users.

Such an image sharing server 108 may be implemented, for example, as a web server. The web server provides a web page for trading and sharing an image between a plurality of first user terminals 102 and second user terminals 106 connected through a network 110 such as a wired or wireless network. More specifically, the image sharing server 108 stores images registered by the user of the first user terminal 102 and stores the registered image (synthesis target image) at the request of the second user terminal 102. to provide. If the user of the first user terminal 102 has set a price on the registered composition target image in this process, the image sharing server 108 charges the corresponding amount from the second user terminal 102, and the charged amount All or part of is paid to the first user terminal 102 using the payment information input by the first user terminal 102. In addition, when the user of the first user terminal 102 is set to donate a portion of the amount, the image sharing server 108 transfers the amount to the charity or the like.

In addition, the image sharing server 108 receives the composite picture from the second user terminal 106 and posts it through a web interface so that it can be shared with other users, and the composite picture is posted on a social network such as Twitter or Facebook. It may include a web or mobile web interface for providing a user account of the service or for rating or commenting on the composite picture.

Hereinafter, with reference to Figures 2 and 4 will be described for the image purchase, composite picture taking and sharing step through the second user terminal 106.

First, the image purchasing step S21 starts by searching for a composition target image registered in the image sharing server 108 by the user of the second user terminal 106 (hereinafter referred to as "second user") (S210). .

Next, if an image to be purchased is selected from the registered composition target images (S211), the second user terminal 106 pays for the image to be purchased. If the payment information of the user is not stored in the image sharing server 108, the second user inputs the payment information of the user (S212), and the input payment information is stored in the image sharing server 108. . Accordingly, the purchase of the synthesis target image is completed (S213), and if necessary, the user may register a rating and a comment on the purchased image on the web page provided by the image sharing server 108 (S214).

On the other hand, the shooting step (S22) for performing the actual shooting by using the purchased composite target image proceeds as follows.

First, the second user selects a synthesis target image previously purchased and stored in the second user terminal 106 (S220). When the synthesis target image is selected, the selected synthesis target image 31 is displayed on the display window of the second user terminal 106 together with the image transmitted from the camera module of the second user terminal 106 as shown in FIG. 4. Is output to That is, in general, a terminal having a camera function displays an image coming into a current lens on a liquid crystal screen. In the present invention, the image to be synthesized is displayed together with the image, such that the second user looks at the liquid crystal. The image to be synthesized and the subject to be photographed have a feeling of taking pictures in the same place.

When the image to be synthesized is displayed as described above, the second user adjusts the position, size, contrast, rotation, and the like on the screen of the selected image so that the image to be combined naturally matches the image to be captured (S221), and presses the capture button. Press to take an image and store it (S222). In this case, the synthesis target image is synthesized and stored in the photographed image at a location designated by a user. Referring to FIG. 4, it can be seen that the extracted image 31 is synthesized by placing the selected extracted image 31 in the screen for photographing. Such a function may provide an effect of photographing with an object that is impossible to actually photograph together, such as a person or object that is not present at the time of shooting, a person or object that does not currently exist, a celebrity, a place that has not been visited, and the like.

Next, the photographed and stored images may be registered in the image sharing server 108 according to the photographer's intention to share (S223) (S224), cyworld, twitter, facebook, etc. You can also upload an image you've saved to a social networking service (SNS) and share it with others. When the synthesized image is registered as described above, the image may be searched or viewed on a shared bulletin board of the image sharing server 108, and other users may also comment or rate the evaluation (S230, S231). .
