Description

[0001] Simultaneous multi-image playing method using multiple mobile devices [

The present invention relates to an image segmentation transmission and image segmentation display technology.

Although the size of the image display device is becoming larger due to the development of the image display device technology, the multivision technology is still required depending on the application. The multivision technology divides one image into a plurality of images, and displays each divided image on a plurality of display devices. Screens provided on the rear wall of a large stage are still provided in the form of a multi-vision in which a plurality of display devices are arranged in a matrix form. Another application of multivision is video artist of artist Nam June Paik, where multivision can have a three-dimensional arrangement. These technologies transmit images to each screen in a state in which the screens constituting one image display system are fixedly arranged. However, they can not be applied to a technique of transmitting a coherent image through a large number of moving screens in a large venue.

In the case of the conventional multi-vision, a communication channel through which one central image processing apparatus transmits a video signal to a plurality of display apparatuses is provided as a wire. At this time, the wiring work is very complicated and errors may occur.

In addition, the conventional multivision has a feature that each display device constituting the multivision is not moved once it is installed. If the display devices are to be moved, it is inconvenient to rearrange the arrangement of the wired communication channels.

As another application similar to the multi-vision technology, an example of providing a consistent visual message by simultaneously driving a display screen installed in a terminal, such as a smart phone, carried by people seated in a chair of a theater or the like is introduced. In this example, it is difficult to limit the movement of people entering the theater, so the communication channel must be provided wirelessly. In addition, since the location of the terminal held by the visitor can be changed from time to time, special techniques are required to realize a desired large screen using the plurality of terminals.

The present invention provides a technique for solving various problems including the above-mentioned problems.

According to an aspect of the present invention, there is provided an image transmission method including: obtaining N geographical coordinates of a geographical location of N terminals; Mapping N image-regions included in one image to the N geo-coordinates; And displaying a kth image-area mapped to the kth geo-coordinate among the N image-areas to a kth terminal corresponding to a kth geo-coordinate of the N geo-coordinates among the N terminals And an image-information transmission step of transmitting information for allowing the user to transmit the information.

In this case, the relative positional relationship between the N image-regions mapped to the N geo-coordinates may be maintained to be the same as the relative positional relationship between the N geo-coordinates.

Mapping the N geo-coordinates to N image-coordinates on one image; And dividing the one image into the plurality of image-areas including the N image-areas, wherein each of the N image-areas comprises the N image-

. &Lt; / RTI > The relative positional relationship between the N image-areas mapped to the N geo-coordinates may be maintained to be the same as the relative positional relationship between the N geo-coordinates.

In this case, if the one image and the k-th image-coordinate corresponding to the k-th geo-coordinate are given, the N image-areas may have the same shape and size, You can have it. The image-information transmission step may include transmitting the k-th image to the k-th terminal, (1) the one image, and (2) the k-th image-coordinate corresponding to the k-th geo-coordinate.

At this time, the image-information transmission step may include transmitting information on all pixels of the k-th image-area to the k-th terminal.

At this time, the information may be information generated by converting the image-region into an audio signal.

According to another aspect of the present invention, there is provided a method of displaying an image in a terminal, comprising: transmitting information on a geographical location of the terminal to a server; And receiving information about the image-area mapped to the geographic location from the server; And displaying the image-area on a screen connected to the terminal. At this time, the server obtains N geographical coordinates of (1) N geographical positions of N terminals including the terminal, (2) obtains N image- (3) mapping to the kth geo-coordinate of the N geo-coordinates of the N terminals to a kth terminal corresponding to the kth geo-coordinate of the N images, k-th image-area.

Here, the information on the image-area may be audio information, and the displaying step may include transmitting the audio information to a separate light emitting device through an audio output terminal included in the terminal, And a decoding unit for converting the audio information into optical information.

According to the present invention, it is possible to display a single coherent large image through display screens of a plurality of terminals which are not fixed at a specific position.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

Figure 1 shows the relative positions of 24 terminals arranged in accordance with an embodiment of the present invention. The terminals may be arranged in a matrix structure of four rows (A to D) and six columns (1 to 6).

The location of each terminal can be obtained by various methods.

As a first example of the location acquisition method of the terminal, each terminal can acquire its own geographical location using a built-in location information detector (ex: GPS). At this time, the geographical location may include information on longitude and latitude. Therefore, when transmitting the acquired geographical location of each terminal to the server, the server can grasp the relative position of each terminal.

A second example of the position acquisition method of a terminal is a method in which a user of each terminal inputs information on a place where the terminal is located through an input unit of the terminal, and the terminal transmits the input information to the server. Such a method can be applied, for example, in the case where terminals are located in a plurality of seats arranged in a performance hall. That is, when the persons having the respective terminals are seated in the respective seats having the 4 * 6 matrix arrangement as shown in Fig. 1, the seat numbers of the seated ones are checked and the seat number is input to the own terminal . In this way, each terminal can acquire the number (ex: A4) of the seat in which it is located and transmit it to the server. At this time, the server may be in a state in which the relative position of the seat arranged in the performance hall is secured in advance. Accordingly, if each terminal transmits the number of the seat in which it is located to the server, the server can grasp the relative position of each terminal.

A third example of the location acquisition method of the terminal is a modification of the second example above. The third example can also be applied when placing terminals in a plurality of seats arranged in a venue. At this time, when the users of each terminal purchase the seating table, the server can collect the number of the seat purchased by the user together with the identification number of the terminal used by the user. For the collection, the ticket office of the seating table can acquire information on the identification number of the terminal and the number of the seat, and deliver it to the server. Alternatively, when the seat ticket is issued through an automatic ticket seller, the automatic ticket seller may acquire information on the identification number of the terminal used by the purchaser from the purchaser of the seat ticket, and may transmit the information to the server together with the seat number. At this time, the server may be in a state in which the relative position of the seat arranged in the performance hall is secured in advance. Accordingly, if each terminal transmits the number of the seat in which it is located to the server, the server can grasp the relative position of each terminal. For example, if the terminal is a mobile phone, the identification number may be a telephone number of each terminal.

As described above, the position of each terminal can be obtained by various methods, and the method of acquiring the position of each terminal in the present invention is not limited to the three examples described above.

Hereinafter, a method of transmitting an image to a plurality of terminals in a server according to an embodiment of the present invention will be described.

In the first step S11 according to the embodiment of the present invention, for example, by using one of the three methods of the location acquisition method of the terminal described above, N 'geographical coordinates Can be obtained. Here, the 'geographical coordinates' may be latitude / longitude information, but it may be information on a plurality of seats in which a relative placement relation is known in advance. For example, the N geographical coordinates may be given as N (= 24) seat numbers (A1 to A6, ..., D1 to D6) shown in FIG.

In the second step S12, the server may divide one image into a plurality of image-areas (M > = N) including N image-areas. At this time, the N image-areas may be mapped to N geo-coordinates obtained in step S11. In this case, the relative positional relationship between the N image-regions mapped to the N geo-coordinates remains the same as the relative positional relationship between the N geo-coordinates.

In the third step S13, the server transmits to the k-th terminal corresponding to the k-th ge-coordinate among the N terminals a k-th image-area mapped to the k-th ge-coordinate among the N image- (Where k is a natural number less than or equal to N).

If all of the above steps S11, S12, and S13 are performed, the N terminals can display the image-area received from the server itself (S14) (each terminal has a built-in display device, Lt; / RTI >

An example in which the terminal displays the image-area received from the server in the display device in step S14 after the above-described steps S11, S12, and S13 are performed in the server will be described with reference to FIG.

In this example, N (= 24) terminals are placed on or installed in seats arranged in a 4 * 6 matrix structure as shown in Fig. Therefore, the server can acquire the geographical coordinates of the N terminals in the form of the seat numbers (A1 to A6, ..., D1 to D6) by the step S11. The one image of step S12 may be given as shown in FIG. At this time, the image of FIG. 2A can be divided into N (= 24) image-areas as shown in FIG. 2B. The N image-areas may be mapped to the N geo-coordinates obtained in step S11. If the N geo-coordinates are given as the above-mentioned seat numbers A1 to A6, ..., D1 to D6, the N geo-coordinates are mapped to the N image- . Then, if the server transmits the image-area to the N terminals in step S13, each terminal can display the received image-area on the display device in step S14. If the relative positional relationship between the N image-areas is maintained to be the same as the relative positional relationship between the N geo-coordinates, when the image-areas displayed by the N terminals are viewed at a distance from one another, . However, for example, if the relative positional relationship between the N image-areas is changed as shown in FIG. 2D, that is, the relative positional relationship between the N image-areas remains the same as the relative positional relationship between the N geo-coordinates Otherwise, when the N-terminal displays the displayed image-areas at a distance from the other, it will be perceived as different from the image of Fig.

Each image-area shown in FIG. 2B is composed of a plurality of pixels, but in an extreme case, one image-area may be one pixel. In addition, the above-described one image may be a still image or a moving image.

In a modified embodiment of the present invention, the second step S12 described above comprises mapping the N geo-coordinates to N image-coordinates on the one image (S121); And dividing the one image into the plurality of image-areas including the N image-areas, wherein each of the N image-areas comprises one of the N image-coordinates, As shown in FIG.

At this time, in another embodiment of the present invention, the image-information transmission step S13 may be performed such that the k-th terminal is given (1) the one image and (2) the k-th image- And transmitting the data. In this case, if the N image-regions have been previously determined so as to have the same shape and size, if the k-th image-coordinate corresponding to the one image and the k-th geographical coordinate is given, It is possible to restore the k-th image-area with only this information. This example can be described as follows with reference to FIG. 2C.

The size of each image-area divided into N in FIG. 2C is equal to each other, and the N image-coordinates described above may be the center coordinates of the N image-areas, respectively. Or the above-described N image-coordinates are given as arbitrary coordinates (ex: corner corner of the lower left corner, corner corner of the lower right corner, corner corner of the upper left corner, or corner corner of the upper right corner) in the N image- It is possible.

Alternatively, in another embodiment of the present invention, the image-information transmission step S13 may include transmitting the entire information about all the pixels of the k-th image-area to the k-th terminal.

Hereinafter, a method of displaying an image in a terminal according to another embodiment of the present invention will be described. The method relates to a method for displaying a received image-area after the terminal receives a specific image-area from the server described above. The method includes transmitting (S21) information about the geographical location of the terminal to the server (S21), receiving information about the image-area mapped to the geographical location from the server (S22) (S23) a screen displayed on the screen connected to the terminal. At this time, the server obtains N geographical coordinates of (1) N geographical positions of N terminals including the terminal, (2) obtains N image- (3) mapping to the kth geo-coordinate of the N geo-coordinates of the N terminals to a kth terminal corresponding to the kth geo-coordinate of the N images, lt; RTI ID = 0.0 > k-th image-area. < / RTI > That is, the server communicating with the terminal may be a server capable of performing the above-described steps S11 to S13.

The one image described above in the present specification is not limited to the image taken by one lens. For example, in the case of video art by artist Nam June Paik, the images displayed on each display device of the multivision may be images photographed through different lenses. In the present invention, 'one image' But may be intentionally combined images combined.

3 is a flowchart illustrating a method of transmitting an image to a plurality of terminals in a server according to an exemplary embodiment of the present invention. In a first step S11, N 'geographical coordinates' of the N terminals' geographical locations can be obtained. In the second step S12, the server may divide one image into a plurality of image-areas (M > = N) including N image-areas. At this time, the N image-areas may be mapped to N geo-coordinates obtained in step S11. The relative positional relationship between the N image-areas mapped to the N geo-coordinates may be maintained to be the same as the relative positional relationship between the N geo-coordinates. In the third step S13, the server transmits to the k-th terminal corresponding to the k-th ge-coordinate among the N terminals a k-th image-area mapped to the k-th ge-coordinate among the N image- (Where k is a natural number less than or equal to N).

4 is a flowchart illustrating a method in which a terminal receives image information from a server and displays the image information on a screen according to an embodiment of the present invention. In a first step S21, information on the geographical location of the terminal can be transmitted to the server. In the second step S22, information about the image-area mapped to the geographical location may be received from the server. In a third step S23, the image-area may be displayed on a screen connected to the terminal.

The technology according to the embodiments of the present invention can be utilized for media art exhibition, media performance, large-scale contents planning and production. It can also be applied to a new type of mass game through a mobile device.

The embodiments of the present invention described above may be understood as follows. That is, a specific image is first transmitted to a plurality of mobile devices. At this time, the entire image can be downloaded or information can be transmitted through streaming. Then, it is possible to designate a specific pixel region that can be defined as all or a binary image that can be formed with the resolution of the transmitted image as the pixel divided region. Here, 'pixel' may be a concept corresponding to the image-area of the above-described embodiment. Then, the image of the image can be divided into pixel regions in the pixel region or pixel regions in the predetermined unit according to the number of the mobile devices to which the image is transmitted. The divided unit images can be given unique relative coordinates in the whole image. Then, in reproduction of the image, it is possible to enlarge and reproduce the image of the coordinate assigned by the individual terminal on the entire screen of the terminal. The shape of the given coordinates may be provided in various forms such as a unit pixel, a video of a specific size, and the like. Then, this relative coordinate can be given to each mobile device. The physical location of the mobile device can be synchronized with the coordinates received, so that the same arrangement as the coordinate arrangement can be configured. Then, the image can be reproduced simultaneously on all mobile terminals in which the coordinates of the physical position and the image are synchronized. At this time, all of the terminal screens should be facing the same direction. If the coordinate size is composed of a single pixel, there may be no problem. However, if the coordinate size is composed of a plurality of pixels, the image may not be properly configured according to the direction in which each terminal looks. At this time, looking at these terminals from a distance will reveal a large image due to the Gestalt effect. Since the image is greatly affected by the surrounding environment, a good image can be obtained if it is performed in a dark environment. Here, when the brightness of the display device (ex: LCD panel) of the terminal is insufficient, the color of the pixel represented by the display device is reinforced by connecting an auxiliary device (e.g., LED stick) to improve the sharpness of the image.

In an embodiment of the present invention, it is assumed that all the people who are seated in a chair of the performance hall have a smartphone to which the present invention is applied. However, some of them may have a 2G terminal which is difficult to perform data communication, for example. At this time, a separate light emitting device such as a light bar can be connected to the earphone jack of the 2G terminal. The light emitting device has a separate power supply and may serve as a particular pixel of the entire image represented by mobile devices located at the venue. The server can encode information on the RGB information and / or the light emission intensity of a specific image pixel into an audio signal and transmit it to the 2G terminal. The 2G terminal having received the signal can transmit the audio signal to the light emitting device through the earphone jack. In this light emitting device, a decoding unit capable of converting the audio signal into RGB information and / or emission intensity may be incorporated. The light emitting device can decode the audio signal and display it in the form of light on a light emitting unit installed in itself according to the result.

The server according to the embodiment of the present invention does not necessarily need to transmit a complex image as shown in FIG. 2A but may also transmit a simple image as shown in FIG. In order to display images at the same level as in FIG. 5, it is not necessary that all the terminals used for the embodiments of the present invention are smartphones, and the light emitting device described above may be connected to the audio output terminal of the terminal. At this time, the geographical coordinates of each terminal can be transmitted to the server by the GPS information or the manual input information of the user when the terminal is a smart phone. If the terminal only provides the voice call and the short message service, Information may be transmitted to the server.
