Method of providing simple broadcasting using personal computer and personal computer system for providing simple broadcasting {METHOD AND PERSNAL COMPUTER SYSTEM FOR SIMPLY PROVIDING BROADCAST}

The present invention relates to a simple broadcast providing method and a personal computer system using a personal computer that can easily provide an image for broadcasting without a professional photographing device or equipment for synthesizing the image.

In the past, most people went to the institute to register and listen to the lectures they wanted. However, due to the development of technology, video lectures have been created, and if a device capable of playing videos can be watched anytime, anywhere, the lectures can be used by many people who want to develop themselves during leisure time in busy schedules. This is increasing.

In general, video lectures can be produced by moving the camera's focus around the lecturer. In this case, the lecturer's description does not match the position of the blackboard placed on the lecturer's background. Often times it is difficult to meet a good understanding.

Therefore, in order to minimize the occurrence of inconsistency between the lecturer and the lecture contents, the lecturer first photographs the lecturer on a special background such as a blue screen, and the lecture contents corresponding to the lecture contents of the lecturer and the image that leave only the lecturer who excludes the background Increasingly, chroma-key technology is used to fit captured images to each other.

However, the above-described chroma key technology takes two images separately and stores them, and recombines the two images, so that it takes not only a long time to produce a desired image, but also stores the captured images. Due to the separation of the equipment to be synthesized, excessive capital investment costs may occur. Therefore, it is impossible to simply provide a broadcast or provide a video in real time at a low cost.

The present invention provides a simple broadcast providing method and a personal computer system using a personal computer that can easily provide a video for anyone using a cheap and popular personal computer without a professional photographing device or equipment for synthesizing an image.

The present invention provides a simple broadcast providing method and a personal computer system using a personal computer that can provide a picture taken with a camera and other images in real time.

According to an exemplary embodiment of the present invention, a method for providing a simple broadcast using a personal computer may include receiving an original image including a photographing object and a background excluding the photographing object, and generating an edited image excluding a background from the original image. Projecting the edited image on the monitor on which the background program is displayed, separately extracting the video signal to the monitor on which the edited image is projected, and transmitting the separately extracted monitor video signal to the outside. have.

As a method of excluding a background from an original image, some chroma key techniques may be adopted. For example, a personal computer that captures a photographing subject using a camera in front of a blue screen, and the personal computer that receives the original image from the camera displays an edited image including only the photographing subject by transparently processing or removing a background other than the subject. You can get it.

On the other hand, the edited video can be produced in a general personal computer, the personal computer can be directly connected to a general camera that can take a video or through wireless communication. Of course, the original image is not excluded from the storage medium provided detachably to the camera.

As described above, by using a personal computer to project the edited image to the monitor on which the background program is displayed, by extracting the video signal to the monitor on which the edited image is projected separately, and transmitting it to the outside, synthesized professional photographing equipment or video Anyone can easily provide a video for broadcasting by using a general camera and a cheap and popular personal computer without any equipment.

In addition, the original image captured by the camera can be received and the edited image can be projected to a background program running on a personal computer in real time and transmitted together.

Background programs include all programs that can be implemented on a personal computer and output from a monitor. For example, various video playback programs such as Windows Media Player and GOM Player, AL See Image reproducing program such as Paint, design drawing program such as auto CAD, SolidWorks, CATIA, pro-e, document such as Word, Korean, Excel, PowerPoint, etc. Authoring programs, image creation and modification programs such as Photoshop, and various entertainment programs, such as fighting and strategy simulation.

On the other hand, in the step of projecting the edited image to the monitor on which the above-described background program is displayed, it is possible to project additional images or additional effects in addition to the edited image, for example, the background program is executed and displayed on the monitor and While the edited image is being projected, additional effects such as strongly processing the color to emphasize the edited image around the edited image, flickering the background, adding a separate pop-up window or a character for beautification, etc. You can project additional images.

In addition, by directly branching the video line connecting the monitor by wire or wireless in a personal computer, it is possible to separately extract the video signal to the monitor.

In addition, the monitor image signal may be encoded and transmitted to the outside, and encoding means converting a form or format of information into another form or format for standardization, security, processing speed improvement, and storage space saving. As referring to a process or a method of processing thereof, for example, encoding or a process of compressing a file or converting a file having an extension of avi to another extension may be included in the encoding.

As described above, the encoded and transmitted monitor video signal may be transmitted to another personal computer and driven through an encoder executed in the other personal computer. Here, the encoder may refer to a device, a circuit, computer software, or algorithm that performs encoding.

In addition, according to another embodiment according to the present invention, a personal computer system for providing a simple broadcast including a computer body, a monitor and a camera connected to the computer body is disclosed. The personal computer system for providing a simple broadcast can be driven by the computer main body, and generates an edited image including the background from an original image including the photographed object and the background except the photographed object, and displays the edited image as a background program. An image editing program projected onto the monitor, an image extracting unit for separately extracting an image signal to the monitor on which the edited image is projected, and a transmitter for transmitting the separately extracted monitor image signal to the outside may be included.

The simple broadcast providing method and the personal computer system using the personal computer of the present invention project the edited image from the personal computer onto the monitor on which the background program is displayed, and separately extracts the video signal from the monitor on which the edited image is projected. By transmitting to the outside, anyone can easily provide a video for broadcasting by using a general camera and a cheap and popular personal computer without a professional photographing device or equipment for synthesizing the image.

Referring to FIG. 1, in the simple broadcast providing method using a personal computer, receiving an original image including a photographing target and a background excluding the photographing target (S110), and generating an edited image excluding a background from the original image ( S120), projecting the edited image to the monitor on which the background program is displayed (S130), extracting the video signal to the monitor on which the edited image is projected (S140), and separately extracting the monitor video signal to the outside. It may include the step of transmitting (S150).

As described above, the simple broadcast providing method includes a computer main body 110, a monitor 120, and a personal computer system including a camera 130 connected to the computer main body 110. It may be implemented at (100). In addition, the personal computer system 100 for providing a simple broadcast includes an image editing program (not shown), an image extractor 140, and a transmitter 150.

The image editing program may be driven by the computer main body 110, and the edited image 230 excluding the background 220 from the original image including the photographing subject 210 and the background 220 except for the photographing subject 210 may be selected. As a program for generating, the edited image 230 may be projected onto the monitor 120 on which the background program is displayed. In addition, the position and size of the edited image 230 may be adjusted by using an image editing program when the edited image 230 is projected. Of course, the object to be photographed 210 may also be completely projected, but in some cases, only a part of the object may be projected through the image editing program.

The image extractor 140 separately extracts an image signal to the monitor on which the edited image 230 is projected. The image extractor 140 may be provided as a wired or wireless line which is directly branched from the image line connecting the monitor to the wired or wireless wire in the personal computer, and may include a distributor installed in a path of the wired or wireless line connecting the personal computer and the monitor. It may be.

The transmitter 150 may be connected to the image extractor 140 and transmit the separately extracted monitor image signal received from the image extractor 140 to the outside. The transmitter 150 may also transmit the monitor image signal to the outside in any of wired and wireless methods. Here, the transmitting unit may be connected to the Internet and displayed on various web sites such as portal sites, personal blogs, and personal homepages so that a plurality of users accessing the Internet can be viewed.

The photographing object substantially refers to an object that is to be obtained through photographing, and the background may refer to an image which is photographed together with the photographing object through a camera and that is not intended to be obtained as a background. For example, the blue screen captured with the photographing subject 210 on the camera 130 in front of the blue screen with the photographing subject 210 in the background, the background 220 is Can be.

Meanwhile, the edited image 230 refers to an image from which the background is removed from the original image in which the photographing target 210 and the background 220 received from the camera 130 are taken together. An edited image including only the photographing subject may be obtained by transparently processing or removing a background other than the photographing subject.

Referring to FIG. 3, a background program is displayed on a monitor by driving a background program in a personal computer. As illustrated in FIG. 3, the edited image may be projected onto a monitor on which a desired background is displayed, and the state of the monitor on which the edited image is projected on the desired background is as shown in FIG. 4.

Background programs include all programs that can be implemented on a personal computer and output on a monitor. For example, various video playback programs such as Windows Media Player, GOM Player, AL see, Image reproducing program such as Paint, design drawing program such as auto CAD, SolidWorks, CATIA, pro-e, document writing program such as Word, Korean, Excel, PowerPoint , Image creation and modification programs such as Photoshop, and various entertainment programs, such as fighting and strategy simulation.

The edited image is projected in real time onto the “desired background 240” displayed on the monitor by the above-described background program. In this case, if the description of the desired background 240 is needed, the edited image 230 can be described. have.

For example, an image of a lecture note may be provided by a background program to a desired background 240, and an instructor's description of the lecture note may be provided in real time together with an edited video. As another example, when the desired background is a design screen using autocad, an edited image corresponding to a description of an instructor corresponding to the design screen may be projected in real time and provided together. In addition to the above-described lectures, it may be possible to provide an excellent travel guide image by projecting a description for guiding the travel destination image on the travel destination image.

In addition, in the projecting of the edited image on the monitor on which the background program is displayed, the additional image or the additional effect may be projected together with the edited image. For example, as shown in FIG. 5, in the state where the background program is executed and displayed on the monitor and the edited image corresponding to the person is projected, the additional image corresponding to the single phase 250 is further projected under the person. It can have the same effect as a person actually teaching in front of a pedestal. In addition, an additional image, such as a pop-up window 260 that displays the core of the contents described by the instructor, may be further projected under the design screen using the autocad. In some cases, it is possible to further project additional effects such as strongly processing a color for emphasizing the edited video, flickering the background, etc. around the edited video.

As described above, the edited image, the additional image or the additional effect is projected on the desired background in real time, and the monitor image signal is transmitted to the monitor 150 through the image extractor 140. In this case, the monitor image signal may be encoded and transmitted to the outside. When the encoded and transmitted monitor image signal is transmitted to the plurality of other personal computers 300, the monitor image signal may be driven through an encoder executed in another personal computer.

The broadcast providing method and the personal computer system according to the present invention do not require a professional photographing device or a device for synthesizing an image, and anyone can easily provide an image for broadcasting by using a general camera and a popular personal computer.

In addition, the above-described broadcast providing method and personal computer system are clearly distinguished from those of synthesizing an image using a conventional chroma key technique for the following reasons, and an excellent effect occurs.

First, the conventional chroma key technique requires equipment for capturing images to be synthesized with each other, and separately prepares a device for synthesizing them. Therefore, excessive facility investment costs are incurred.

However, the personal computer system according to the present invention can establish a facility for broadcasting and provide broadcast video at low cost by using a camera and a popular personal computer.

Second, in the conventional chroma key technique, since a video to be synthesized is separately captured and stored, and then synthesized again, it takes not only a long time to produce a desired video, but also after storing the synthesized video again, It could be provided to the outside through a method of transmitting the data or providing it in a separate storage medium.

However, since the broadcast providing method or the personal computer system according to the present invention can receive the image captured by the camera and simultaneously project the edited image to the background program executed on the personal computer, it can be transmitted to the outside together. Not only does not go through the synthesis process, it can immediately produce a broadcast image, and provide it to the outside.

In addition, if the camera and the personal computer is directly connected via wired or wireless, it is also possible to provide an image for broadcasting at the same time shooting by providing the original image captured by the camera to the computer main body in real time.

As described above, although described with reference to the preferred embodiment of the present invention, those skilled in the art various modifications and variations of the present invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
