The present invention relates to a chroma key remote synthesis synchronization system and method, and more particularly, to a chroma key remote synthesis synchronization system and method capable of obtaining a high quality chroma key composite image.

In general, a chroma key is a background used to take advantage of special effects such as screen compositing, often referred to as a green screen or a blue screen using a green or blue background. In this way, images taken on a monochromatic background can be edited with a monochromatic portion as a different background, thereby giving effects photographed on totally different backgrounds.

With the recent development of smartphone camera hardware and the development of photo applications used in smart phones, it has become very convenient to easily obtain images of excellent image quality and to edit acquired images. In addition, with the development of SNS, interest in creating and sharing original images is increasing.

Hereinafter, the configuration and operation of the chroma key remote synthesis synchronization system according to the preferred embodiment of the present invention will be described in more detail.

First, the 'video' used in the present invention is a continuous structure of a plurality of frames and may be a moving picture having a predetermined playback time or a picture composed of one frame.

The monitoring device 30 and the photographing device 40 are physically separated from each other and can be connected to the service provider server 10 or the composite service server 20 with a single member ID. .

The monitoring device 30 may be an apparatus capable of displaying an image or an image and receiving a user's selection, and may be a device including a display such as a smart phone, a smart pad, a computer, and input means.

The photographing unit 40 includes at least a camera capable of photographing a high-quality image, and a communication device unit for communicating with the composite service server 20, a monochrome background unit for obtaining a chroma key image.

The service provider server 10 collects users who are members for service provision, opens a member DB 11 based on information for identifying each member at the time of membership registration, and stores the background image And a DB 12.

The composite service server 20 includes an image matching unit 21 for matching the chroma key image photographed by the photographing unit 40 and the background image selected by the monitoring device 30 in a one-to-one correspondence, A chroma key image editing unit 22 for removing the monochrome image from the chroma key image editing unit 22, a synthesizing unit 23 for synthesizing the chroma key image editing unit 22 with the matched background image, a storage unit 24 for storing the synthesized image, As shown in FIG.

2 is a flowchart of a chroma key remote synthesis synchronization method according to a preferred embodiment of the present invention.

1, the user first connects to the service provider server 10 using the monitoring device 30 as in step S21, and transmits the background image DB 12 Search for the appropriate background image.

3 is an exemplary configuration view of the monitoring device 30. As shown in FIG.

An application (or an application program) is installed in the monitoring device 30, and the monitoring application 30 is connected to the service provider server 10 by executing the application.

The application includes a background display unit 31 for displaying a currently selected background image at the center of the display of the monitoring device 30 and a chroma key selection unit 31 for selecting a chroma key color and a density in the background image on the left side of the background display unit 31 And an icon display unit 33 for displaying selectable background images on the right side of the background display unit 31 as small icons.

And a synchronization selection unit 34 for selecting a part of the background display unit 31 and selecting and synchronizing the background image displayed on the current background display unit 31. [

When the application of the monitoring device 30 is executed, a list of background images is downloaded from the service provider server 10 and displayed on the icon display unit 33. When the user selects a specific background image of the icon display unit 33, And displays the selected background image on the background display unit 31.

The user can select the chroma key portion from the background image displayed on the background display portion 31 of the monitoring device 30 through the chroma key selection portion 32. [

Here, the meaning of the chroma key selection is to divide a specific part of the background image into a front background image positioned in front of the chroma key image and a rear background image located behind the chroma key image.

At this time, the chroma key selection is made according to the selection of the color and the density. That is, it is assumed that the background images provided by the service provider server 10 can be divided into regions according to color and density, and the user uses the chroma key selection unit 32 to determine a position to insert a subsequent chroma key image .

After completing the selection of the chroma key, the synchronization selector 34 is selected to use the background image.

When the background is selected through the synchronization selection unit 34, the information capable of distinguishing the selected background image, the chroma key information selected through the chroma key selection unit 32, and the selected time information are transmitted to the service provider server 10 And is stored in the member DB 11.

In the above description, the monitoring device 30 is a smart phone or a smart pad, but the background image may be synchronized through the PC.

In step S22, the background image selected in the background image DB 12 is recorded in the member DB of the service provider server 10. The information at this time includes the unique number of the background image and the time information selected as background in the monitoring device 30.

Next, in step S23, the user directly controls the photographing unit 40 to photograph a high-resolution photograph, or a user visits a specific studio to request a photographing of a chroma key image to take a high-resolution chroma key photograph, And transmits the Maki image to the composite service server 20.

As described above, the photographing unit 40 can capture a high-quality chromakey image by photographing with a high-quality camera with a photographing object desired to be photographed by a user on a monochromatic background such as green or blue, To the synthetic service server (20).

4 is an example of a chroma key image photographed by the photographing unit 40. Fig.

Then, in step S24, the composite service server 20 confirms the time information of the high-resolution chroma key image. Generally, a digital photograph or an image includes meta information, and the time taken at the photographing unit 40 can be confirmed through this information.

After the time information (time information) at which the chroma key image was captured is confirmed, the image matching unit 21 confirms the information of the background image stored in the service provider server 10, The background image synchronized with the time of closest to the photographing time of the chroma key image among the background images selected before the photographing time of the chroma key image is matched.

By automatically matching the chroma key image and the background image in this manner, the present invention has an advantage that the user does not need to directly match the background image and the chroma key image through the monitoring device 30.

Then, in step S25, the chroma key image editing unit 22 edits the chroma key image. At this time, editing means removing (or making transparent) the background of the chroma key image photographed by the photographing unit 40.

Then, in step S26, the edited chroma key image and the 1: 1 matched background image are synthesized.

FIG. 5 shows an example of a composite image synthesized through the present invention, in which the background image of FIG. 3 and the chroma key image of FIG. 4 are combined into one image.

Then, the synthesized image is stored as in step S27, and the stored composite image is provided at the request of the monitoring device 30 or the photographing device 40. [

Although the composite service server 20 described in the above embodiment is described and described as a single server associated with the service provider server 10, the present invention is not limited to this, Lt; / RTI >

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
