The present invention relates to a method for providing a multi-photographing service using a plurality of terminals in a mobile communication system, and more particularly, to a method for providing a multi-photographing service using a wireless Internet server.

Due to the development of various electronic and communication industries, portable wireless terminals have been widely used, and the functions of the terminals have been diversified in order to meet the needs of users.

In addition to the simple call function in software, various functions of downloading and listening to music files, receiving VOD (Video On Demand) files, watching videos, or shooting a predetermined subject and storing them as albums are being added. to be.

In addition, peripheral devices that are used by being attached or added to the terminal in hardware are also developing. For example, a detachable or built-in digital camera device, a TV receiving means capable of listening to over-the-air broadcasts, an ear microphone device mounted on a terminal and capable of talking Can be classified. In particular, the camera phone, which is popular in Korea, was first introduced to the market in April 2002, and since 2003, its sales weight has continuously increased, exceeding half of the mobile phone market.

As such, although the high-definition camera phone has been popularized, its use is limited to simple photography, and there is a demand for a method to utilize the camera phone in various fields.

In the case of a mobile communication terminal having an existing camera, since the object (subject) to be photographed can be photographed only at a single angle and place, it is insufficient to photograph a rotating or moving subject.

Mobile communication systems are largely divided into US-led synchronous (eg CDMA2000) and European and Japanese-led asynchronous (eg WCDMA). The synchronous method receives time information from a GPS (Global Positioning System) satellite at all base stations and adjusts the time equally, thereby enabling real-time call regardless of the user's location. It is a method of inducing real time call by adjusting time between base stations with equipment. Looking at this in another aspect, in the synchronous mobile communication system, it means that the shooting time can be controlled for each of the plurality of terminals.

If one subject is photographed using a plurality of terminals, if each photographing time can be controlled, the subject may be photographed more actively and dynamically. In particular, a plurality of time-synchronized photographing data (pictures) may be utilized in various fields, for example, animation production, which produces moving images by continuously arranging static images.

 Accordingly, an object of the present invention is to provide a method for multiple photographing a subject using a plurality of terminals.

Another object of the present invention is to provide a wireless Internet server providing a service for multi-photographing a subject using a plurality of terminals and a control method thereof.

Another object of the present invention is to provide a method for one terminal to control camera functions of a plurality of terminals.

Still another object of the present invention is to provide a method for one terminal to control a shooting time of a plurality of terminals.

And transmitting a shooting command signal to the master terminal and the slave terminals when receiving a shooting request signal from the master terminal.

According to a second aspect of the present invention, when one master terminal controls the camera functions of a plurality of slave terminals via a wireless Internet server, an operation method of the master terminal is to establish a group for multi-shooting with the wireless Internet server. Requesting information, receiving and displaying information on slave terminals participating in the group, and transmitting a message requesting camera function setting to each of the master terminals and the slave terminals to the wireless Internet server. And setting a camera function based on the received information when receiving camera function setting information from the wireless internet server, and after setting the camera function, transmitting a photographing request signal to the wireless internet server by a user operation. Process and a photographing name from the wireless Internet server Upon receiving a signal, photographing a subject according to the set camera function, transmitting the photographed image data to a wireless internet server, and receiving and storing captured image data of other terminals participating in the group from the wireless internet server. Characterized in that it comprises a process.

According to a third aspect of the present invention, when one master terminal controls the camera functions of a plurality of slave terminals via a wireless Internet server, a method of operating a slave terminal is established for multiple shooting by accessing the wireless Internet server. Receiving and displaying a list of the groups, transmitting a signal for selecting one of the lists to the wireless Internet server, registering the slave group as a slave terminal of the corresponding group, and receiving camera function setting information from the wireless Internet server. Setting a camera function based on the received information, and when receiving a recording command from the wireless Internet server after setting the camera function, photographing a subject according to the set camera function, and wirelessly recording the photographed image data. Transmitting to an internet server, and from the wireless internet server And receiving and storing photographed image data of other terminals participating in the group.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention will be described with respect to a technique for multiple photographing a subject using a plurality of mobile communication terminals. Such a multi-photographing service may be provided through a wireless internet server. In particular, the present invention is for one terminal to control the camera function (including shooting time) of a plurality of terminals, the following description is synchronous mobile communication in which all the terminals are synchronized to the absolute time provided by the Global Positioning System (GPS) We will assume the system. In the case of the asynchronous system, one terminal can take multiple shots for controlling the shooting of a plurality of other terminals. However, the asynchronous system cannot accurately control the shooting time because the time information of the terminals is different. Accordingly, the present invention can be implemented in both a synchronous and asynchronous system from a multiple photographing point of view using a plurality of terminals, but only in a synchronous system in order to precisely control the shooting time. In other words, it will be appreciated that the multi-capture function according to the present invention is not limited to the synchronous system.

1 shows a network configuration applied to the present invention.

As shown, the network according to the present invention largely comprises a mobile communication terminal 4, a mobile communication network (1), the Internet (2) and a wireless Internet server (3).

2 shows a more detailed configuration of FIG. 1.

As shown, the mobile communication network 1 includes a base station (BTS) base station (BTS) 200, a control station (BSC: base station controller) / packet control unit (PCF: packet control function) (201), an exchange station ( MSC: Mobile Switching Center (202), Home Location Register (HLR: Home Location Register, not shown), Visitor Location Register (VLR: Visitor Location Register, not shown), Packet Data Service Node (PSDN: Packet Data Service) Node / FA (foreign agent) (203), carrier's intranet (206), authorization / authentication / billing (AAA), home agent (HA) ( 205) and the like.

Referring to FIG. 2, the mobile communication terminal 4 is in the range of an arbitrary base station 200, and the information of the mobile communication terminal 4 passes through the base station 200 and the control station 201 that controls it. The information transmitted to 202 and transmitted from the switching center 202 is transmitted to the mobile communication terminal 4 via the control station 201 and the base station 200. The mobile communication terminal 4 is meant to include all terminals capable of communicating (circuit communication and packet communication) while the user is carrying and moving.

The base station 200 is responsible for connecting the mobile communication terminal 4 to the control station 201, and communicates with the mobile communication terminal 4 by radio, and communicates with the control station 201 by wire. Perform the wired / wireless conversion function. The control station 201 controls the connection between the base stations 200 by connecting the base station 200 to the switching center 202, and is responsible for the signal processing function for communication between the base station 200 and the switching station 202. The packet control unit (PCF) in the control station 201 processes packet data in association with the packet data service node 203.

The packet data service node 203 is responsible for an interface function between a radio access network (RAN) and a data core network 206. In other words, it terminates the data link layer from the mobile communication terminal 4 and performs a function for routing to a higher layer protocol on the data network. In this case, as a method of connecting to a data network, a simple IP call is directly connected to an IP network (Internet), and a mobile IP call is GRE (Generic Routing Encapsulation) tunnel. Connect to home agent (HA) through.

The home agent 205 serves as a gateway for the mobile IP user to access the Internet. The home agent 205 performs tunneling with the PSDN 203 for MIP registration and delivers a MIP call packet from the home network to the PSDN 203.

Accordingly, when the mobile communication terminal 4 attempts to access a specific service providing server 3 connected to the Internet 2, first, the AAA 204 performs subscriber authentication. If the subscriber authentication is successful, the home agent (or visiting agent) allocates the IP address to be used for packet communication to the mobile communication terminal 4 (in case of using mobile IP). Thereafter, the mobile communication terminal 4 performs packet communication with the assigned IP address. In this way, when connected to the wireless Internet server 3, the mobile communication terminal 4 can use a variety of services provided to the server (3). The representative wireless Internet servers 3 in Korea include NATE provided by SK Telecom and Magic N 106 provided by KT Freetel. Since the wireless Internet server 3 follows the configuration of a general Internet server, detailed configuration description thereof will be omitted.

3 is a block diagram of a mobile communication terminal according to the present invention. In the following description, the mobile communication terminal is meant to include a cellular phone, a personal communication system (PCS), an international mobile communication-2000 (IMT2000) terminal, and the like. I will explain with a general configuration.

Referring to FIG. 3, a control unit (MPU: Micro-processor unit) 300 controls the overall operation of the mobile communication terminal. For example, processing and control for voice call and data communication are carried out, and in addition to the usual functions, the multi-shot function for taking a subject together with a plurality of other terminals is processed according to the present invention. For example, when the mobile communication terminal operates as a master, it controls the camera functions of a plurality of terminals connected to the wireless Internet server 3. In the following description, description of the processing and control of the conventional control unit 300 is omitted.

The memory 301 includes a program memory, a data memory, a nonvolatile memory, and the like. The program memory stores a program for controlling the overall operation of the mobile communication terminal. The program memory may use a flash memory. The data memory temporarily stores data generated during the operation of the mobile communication terminal. The data memory may use random access memory (RAM). The nonvolatile memory stores telephone numbers and system parameters registered to perform functions such as speed dialing. The nonvolatile memory may use an EEPROM.

The key pad 302 includes 0 to 9 numeric key buttons, a menu button, a cancel button, a confirm button, a call button TALK, an end button END, and an internet access button. And a plurality of function keys such as navigation key buttons (▲ / ▼ / ◀ / ▶), and provide key input data corresponding to a key pressed by the user to the controller 300. The display unit 303 displays the state information generated during the operation of the mobile communication terminal, a limited number of characters, a large amount of moving images and clear images, and the like. The display unit 303 may use a color liquid crystal display (LCD).

A codec (Coder-Decoder) 304 connected to the control unit 300, and a speaker and a microphone connected to the codec 304 are voice input / output blocks used for a telephone call. The codec 304 converts the PCM data provided from the controller 300 into an analog voice signal and sends the same through the speaker, and converts the voice signal received through the microphone into PCM data to the controller 300. to provide.

A radio frequency unit (RF) unit 305 lowers the radio frequency signal received through the antenna to the modem unit 306 and raises the baseband signal from the modem unit 306 to increase the frequency. Send via The modem unit 306 processes the baseband signal transmitted and received between the RF unit 305 and the control unit 300. For example, in case of transmission, channel coding and spreading of data to be transmitted are performed, and in case of reception, despreading and channel decoding of a received signal are performed. .

The camera 309 converts an optical signal incident to the lens into an electrical signal, converts the electrical signal into digital data (image data), and outputs the converted digital signal to the controller 300. For example, the camera 309 may use a complementary metal oxide semiconductor (CMOS) camera. A moving picture experts group (MPEG) codec 307 is a block for compressing and decompressing a moving picture. For example, the MPEG codec 307 compresses the image data from the control unit 300 according to a compression method (eg, JPEG (Joint Photographic Export Group)) standard and compresses the compressed frame to the image file storage unit 308. And stores the compressed frames read from the image file storage unit 308 and outputs the compressed frames to the display unit 303.

Next, the operation of the present invention based on the above configuration will be described in detail.

In the following description, a "multi-shot group" indicates a group of terminals for photographing the same subject. Among the terminals constituting the group, one terminal that actively controls multiple photographing will be referred to as a "master terminal" and the other terminals will be referred to as a "slave terminal".

4 illustrates a procedure for providing a multi-photographing service in the wireless Internet server 3 according to an embodiment of the present invention. In particular, Fig. 4 shows in advance that the communication is made mainly between the wireless Internet server 3 and the master terminal. Since the communication between the wireless Internet server 3 and the slave terminal will be described in detail with reference to FIG. 6, detailed descriptions thereof will be omitted.

Referring to FIG. 4, first, in step 401, the wireless Internet server 3 checks whether a terminal is connected. As described above, the terminal is connected to the wireless Internet server 3 via the mobile communication network 1 and the Internet (2). If the connection of the terminal is detected, the wireless Internet server 3 proceeds to step 403 and transmits a top menu page to the terminal. The top menu page is the first page displayed on the terminal when the wireless Internet server 3 is connected, and the page includes a plurality of menu items. Among the plurality of menu items, the "multiple shoot" menu item is included according to the present invention.

After transmitting the top menu page, the wireless Internet server 3 checks whether a signal for selecting a multi-photography menu is received from the terminal in step 405. If the multi-shot menu selection signal is not received, the wireless internet server 3 proceeds to step 449 to perform a corresponding function according to the received menu selection signal. If the multi-shot menu selection signal is received, the wireless Internet server 3 proceeds to step 407 to transmit the main page of the multi-shot menu to the terminal. Here, the main page of the multi-shot menu includes a plurality of selection items. The main page may include, for example, selection items such as “1; master registration 2: group participation”.

After transmitting the main page of the multi-shooting menu, the wireless Internet server 3 checks whether a signal for selecting a master registration item is received from the terminal in step 409. If the master registration selection signal is not received, the wireless internet server 3 proceeds to step 451 and performs a corresponding function according to the received item selection signal (eg, group participation selection signal). If the master registration selection signal is received, the wireless Internet server 3 proceeds to step 411 to register the terminal as a master terminal and transmits a group information input request screen to the terminal. The group information input request screen includes a message requesting input of a group name and a brief group description.

After transmitting the group information input request screen, the wireless Internet server 3 checks whether a group establishment request signal including group information is received from the master terminal in step 413. When the group establishment request signal is received, the wireless Internet server 3 establishes a multi-shooting group based on the received group information in step 415 and masters a main page for displaying the participants of the established group. Send to the terminal. In addition, the main page includes a button for requesting transmission of camera function information, a shooting button, and the like.

In step 417, the wireless Internet server 3 receives camera function information (e.g., shooting time, storage size, image quality selection, flash on / off, special effect shooting, backlight compensation, continuous shooting, etc.) from the master terminal. Check that the same information is received). Upon reception of the camera function information of the master terminal, the wireless internet server 3 proceeds to step 419 to register the camera function information of the master terminal.

In step 421, the wireless Internet server 3 checks whether there is a slave terminal participating in the group. In this case, when the group participant occurs, the wireless Internet server 3 proceeds to step 423 and transmits participant information (name, phone number, etc.) to the master terminal. In this case, a screen requesting transmission of camera function information is transmitted to the slave terminal.

In step 425, the wireless Internet server 3 checks whether camera function information is received from the slave terminal. If the camera function information of the slave terminal is not received, the wireless internet server 3 proceeds to step 429. If the camera function information of the slave terminal is received, the wireless internet server 3 proceeds to step 427. Proceed to register the camera function information of the slave terminal.

After registering camera function information of the slave terminal, the wireless Internet server 3 checks whether a signal for requesting camera function information of a group participant is received from the master terminal in step 429. Here, the group participant is meant to include both the master terminal and the slave terminal. This means that the master terminal can download and modify not only the slave terminal but also its camera function information from the wireless Internet server. If the request signal is not received, the wireless Internet server 3 returns to step 425. If the request signal is received, in step 431, the camera function information of the participant is read and transmitted to the master terminal. At this time, the master terminal modifies the camera function information of the corresponding participant, and transmits the same to the server 3 again. As described above, the camera function information includes information such as shooting time, storage size, image quality selection, flash on / off, special effect shooting, backlight compensation, continuous shooting, and the like.

Here, the photographing time is for controlling the photographing time of the terminal. Basically, it is assumed that the photographing time is set in units of 00: 00 minutes 00 seconds, but up to a unit (ms) below it may be set. When the photographing time is set differently for each terminal, image data photographed at different times for one subject may be acquired. If the shooting time is not set, the terminals perform shooting at the time when the shooting command is received.

On the other hand, in the case of the asynchronous mobile communication system it is not possible to control the shooting time accurately, if you want to acquire the image data shot at different times, if you want to take a picture from a time after receiving the shooting command instead of the shooting time Time-division multiplexing can be implemented using the delay time information indicating whether or not. The terminals participating in the photographing do not perform the photographing immediately after receiving the photographing command from the upper system, but perform the photographing after delaying the delayed time. In this case, it is not possible to perform precisely synchronized time-division multiplexing as in a synchronous system, but it is possible to acquire image data (pictures) of different scenes that can be read by human beings.

Meanwhile, after transmitting the camera function information of the corresponding participant to the master terminal, the wireless internet server 3 checks whether a camera function setting request signal is received from the master terminal in step 433. Here, the camera function setting request signal includes modified camera function information of the corresponding terminal. Upon receiving the camera function setting request signal, the wireless Internet server 3 proceeds to step 435 to store the modified camera function information in response to the corresponding participant, and notifies the corresponding participant terminal of the camera function setting information. do. Then, the participant terminal sets its own camera function according to the camera function setting information received from the wireless Internet server 3. In this way, the camera function is set for each group participant through steps 433 and 435.

In step 437, the wireless Internet server 3 checks whether a photographing request signal is received from the master terminal. In this case, if the photographing request signal is not received, the wireless Internet server 3 returns to step 421 and performs the following steps again. If the photographing request signal is received, the wireless Internet server 3 proceeds to step 439 to master. The photographing command signal is transmitted to the group participants including the terminal. The terminals receiving the photographing command signal photograph the subject according to a preset camera function, and transmit the image data obtained by photographing to the server 3.

After transmitting the photographing command signal, the wireless Internet server 3 checks whether image data photographed from the terminals participating in photographing is received in step 441. In this case, if the image data is not received, the wireless Internet server 3 proceeds to step 445. If the image data is received from any one, the wireless Internet server 3 proceeds to step 443 and transmits the image data. The received image data is transmitted to the remaining terminals.

Thereafter, the wireless Internet server 3 proceeds to step 445 and checks whether a connection termination signal is received from one of the terminals. The connection termination signal includes information of a terminal disconnected from the mobile communication network 1. If the access termination signal is not received, the wireless Internet server 3 returns to step 441. If the access termination signal is received, the mobile internet server 3 proceeds to step 447. The terminal disconnects from the mobile communication network 1. After deleting information on the camera function information, the process returns to step 441.

In the above-described embodiment, it is described that the participant information and the camera function information are separately downloaded to the master terminal. However, the wireless Internet server 3 may also implement the camera function information when the participant information is delivered to the master terminal. have.

On the other hand, the above-described embodiment has been described that all the terminals participating in the group upload their own camera function information to the server, this process can be omitted. In this case, the server should store basic camera function information in advance, and when the master terminal wants to set the camera function of the group participant, the server transfers the basic camera function information stored in advance to the master terminal. Then, the master terminal modifies and transmits the camera function information received from the server to the server, and the server lowers the camera function information from the master terminal to the corresponding participant. At this time, the participant sets the camera function according to the camera function information received from the server, and ignores the functions not supported and sets the camera function. For example, if the camera function information received from the server includes a shooting time, continuous shooting or black and white shooting, and the camera function that the participant terminal can support is the shooting time setting and continuous shooting setting, The black and white photographing information is ignored and the camera function is set.

Next, the operation of the master terminal and the slave terminal will be described in detail.

5 illustrates a procedure for performing a multi-capture function in a master terminal according to an embodiment of the present invention.

Referring to FIG. 5, first, in step 501, the master terminal attempts to access the wireless Internet by a user's button manipulation, and checks whether the wireless internet connection is successful. At this time, if the wireless Internet access is successful, a traffic channel is established between the terminal and the base station 200. Thereafter, the base station 200 and the terminal exchange necessary information through the traffic channel.

After the wireless Internet connection, the master terminal receives the top menu page from the wireless Internet server 3 in step 505 and displays it on the display window. The top menu page includes a plurality of menu items, including a "multiple shoot" menu item according to the present invention. After displaying the top menu page, the master terminal transmits a multi-shooting menu selection signal to the wireless Internet server 3 by a user's button manipulation in step 507.

In operation 509, the master terminal receives and displays the main page of the multi-shooting menu from the wireless Internet server 3 in response to the menu selection signal. The main page of the multi-shot menu includes a plurality of selection items (1: master registration 2: group participation).

In the state of displaying the main page of the multi-shooting menu, the master terminal proceeds to step 511 and transmits a master registration item selection signal to the wireless Internet server 3 by a user's button manipulation. In step 513, the master terminal receives and displays a group information input request screen from the wireless Internet server 3 in response to the item selection signal. The group information input request screen includes a message requesting input of a group name and a brief group description.

When the user inputs group information, the master terminal transmits a group establishment request signal including information input by the user to the wireless Internet server 3 in step 515. In step 517, the master terminal receives and displays the main page of the establishment group from the wireless Internet server 3 in response to the group establishment request signal. Here, the main page of the establishment group displays the members of the group and includes a button and a shooting button for requesting transmission of camera function information.

Then, when the user inputs the camera function information transmission button displayed on the main page, the master terminal in step 519 camera information (for example, shooting time, storage size, image quality selection, flash on / off, special effects shooting) Information such as whether or not, backlight compensation, continuous shooting, etc.) is transmitted to the server 3.

In operation 521, the master terminal receives and displays information on slave terminals participating in the group from the server 3. In this way, when the group is configured, the master terminal proceeds to step 523 and determines whether one of the group participants (including the master terminal) is selected by the user's button manipulation. If the participant selection is detected, the master terminal proceeds to step 525 and transmits a signal for requesting the camera function information of the selected participant to the server 3. In operation 527, the master terminal receives and displays the camera function information of the participant from the server 3 in response to the request signal.

At this time, the user resets the camera function by modifying the displayed information. Specifically, the user may set the shooting time, storage size, image quality selection, flash on / off, special effect shooting, backlight compensation, continuous shooting, and the like. In particular, the shooting time is for designating the time (00: 00: 00 seconds) for the terminal to shoot, and as mentioned earlier, if the shooting time of the group participants are set differently, the image data photographed at different times Can be obtained. In this way, the master terminal can adjust the shooting time of the terminals participating in the group.

In the state of displaying the camera function information, the master terminal proceeds to step 529 and checks whether the camera function is set again. If it is determined that the camera function is set again, the master terminal proceeds to step 531 and transmits a camera function setting request signal including the modified camera function information to the server 3.

After transmitting the camera function setting request signal, the master terminal checks in step 533 whether photography is selected by a user's button manipulation. In this case, if the photographing is not selected, the master terminal returns to step 523 in order to set a camera function of another participant, and performs the following steps again. When the photographing is selected, the master terminal proceeds to step 535 and photographing request signals. Is transmitted to the server (3).

In step 537, the master terminal checks whether a photographing command signal is received from the server 3. In this case, when the photographing command signal is received, the master terminal proceeds to step 539 and photographs a subject according to a camera function currently set. In operation 541, the master terminal transmits the image data obtained by the photographing to the server 3.

After transmitting the image data, the master terminal checks whether image data of another terminal is received from the server 3 in step 543. If the image data of the other terminal is not received, the master terminal proceeds to step 547. If the image data of the other terminal is received, the master terminal proceeds to step 545 to store the received image data in a preset image. Save to the area. As such, the stored image data may be photographs of the same subject photographed at different angles and at different times.

After storing the received image data, the master terminal proceeds to step 547 to check whether the connection is terminated by a user's button manipulation. If the termination of the connection is not detected, the master terminal returns to step 543 to receive image data of another terminal. If the termination of the connection is detected, the master terminal proceeds to step 549 and transmits an access termination request signal to the mobile communication network 1. In this way, when the connection between the terminal and the mobile communication network 1 is terminated, the mobile communication network 1 notifies the server 3 of the termination of the connection.

6 illustrates a procedure for performing a multi-capture function in a slave terminal according to an embodiment of the present invention.

Referring to FIG. 6, in operation 601, a slave terminal attempts to access a wireless Internet by a user's button manipulation and checks whether the wireless internet connection is successful. At this time, if the wireless Internet access is successful, a traffic channel is established between the terminal and the base station 200. Thereafter, the base station 200 and the terminal exchange necessary information through the traffic channel.

After the wireless Internet connection, the slave terminal receives the top menu page from the wireless Internet server 3 in step 603 and displays it on the display window. The top menu page includes a plurality of menu items, including a "multiple shoot" menu item according to the present invention. After displaying the top menu page, the master terminal transmits a multi-shooting menu selection signal to the wireless Internet server 3 by a user's button manipulation in step 604.

In step 605, the master terminal receives and displays the main page of the multi-shooting menu from the wireless Internet server 3 in response to the menu selection signal. The main page of the multi-shot menu includes a plurality of selection items (1: master registration 2: group participation).

In the state of displaying the main page of the multi-shooting menu, the master terminal proceeds to step 606 and transmits a "group join" item selection signal to the wireless Internet server 3 by a user's button manipulation. In step 607, the master terminal receives and displays a list of established groups from the wireless Internet server 3 in response to the item selection signal.

In the state where the list of the opened multi-shot groups is displayed, the slave terminal proceeds to step 611 to check whether group participation is selected by user button manipulation. If the group participation is detected, the slave terminal proceeds to step 613 and transmits a group join request signal to the server 3. In operation 615, the slave terminal receives and displays the main page of the group from the server 3 in response to the request signal. The main page displays members of the group, and includes a button and a shooting button for requesting transmission of camera function information.

In the state where the main page of the corresponding group is displayed, the slave terminal proceeds to step 617 and checks whether camera function information transmission is selected by a user's button manipulation. In this case, when the transmission of the camera function information is selected, the slave terminal proceeds to step 619 in which the camera function information (for example, shooting time, storage size, image quality selection, flash on / off, whether to take special effects or not), and backlighting is currently set. Information such as correction, continuous shooting, etc.) is read out and transmitted to the server 3.

In operation 621, the slave terminal determines whether camera function setting information is received from the server 3. Upon receiving the camera function setting information, the slave terminal sets a camera function based on the received information in step 623. After setting the camera function, the slave terminal checks whether a photographing command is received from the server 3 in step 625. In this case, if the photographing command is not received, the slave terminal returns to step 621 and performs the following steps again. If the photographing command is received, the slave terminal proceeds to step 627 and the subject according to the currently set camera function. To shoot. The slave terminal transmits the image data obtained by the shooting in step 629 to the server 3.

After transmitting the image data, the slave terminal checks whether image data of another terminal is received from the server 3 in step. If the image data of the other terminal is not received, the slave terminal proceeds to step 635, and when the image data of the other terminal is received, the slave terminal proceeds to step 633 to store the received image data in a preset image. Save to the area. The stored image data may be photographs of the same subject photographed at different angles and at different times.

After storing the received image data, the slave terminal proceeds to step 635 to check whether the connection is terminated by the user's button operation. If the termination of the connection is not detected, the slave terminal returns to step 631 to receive image data of another terminal. If the termination of the connection is detected, the slave terminal proceeds to step 637 and transmits an access termination request signal to the mobile communication network 1. As such, when the connection between the terminal and the mobile communication network 1 is terminated, the mobile communication network 1 notifies the server 3 of the termination of the connection.

Here, the overall operation according to the present invention will be described based on the messages exchanged between the master terminal, the server and the slave terminal. In the following description, since the wireless Internet page downloaded from the server 3 by the terminal has been sufficiently described above, a detailed description thereof will be omitted.

7 is a diagram illustrating messages exchanged for multiple shooting in a mobile communication system according to the present invention. Hereinafter, it is assumed that two terminals photograph one subject. In this case, one terminal acts as a master terminal and the other terminal acts as a slave terminal.

Referring to FIG. 7, in step 701, the master terminal accesses the wireless Internet server 3 and transmits a multi-shot group establishment request message to the wireless Internet server 3 in step 703.

Upon reception of the multi-shooting group establishment request message, the wireless Internet server 3 establishes a multi-shooting group based on the information included in the group establishment request message in step 705 and stores the established group information.

In operation 707, the master terminal transmits a message including the camera function information, which is currently set, to the wireless Internet server 3. Here, the camera function information is information such as shooting time, storage size, image quality selection, flash on / off, special effect shooting, backlight compensation, continuous shooting, and the like.

When receiving a message including the camera function information, the wireless Internet server 3 stores the received camera function information in correspondence with the master terminal in step 709.

In operation 711, the slave terminal accesses the wireless Internet server 3, and transmits a group selection message to the wireless Internet server 3 to join the established group in operation 713. In operation 717, the slave terminal transmits a message including the camera function information, which is currently set, to the wireless Internet server 3.

Upon receiving a message including the camera function information from the slave terminal, the wireless internet server 3 stores the received camera function information in correspondence with the slave terminal in step 719.

In operation 721, the master terminal transmits a message requesting camera function information of the slave terminal to the wireless Internet server 3. Then, in response to the request message, the wireless Internet server 3 reads out camera function information of the slave terminal and transmits it to the master terminal.

When the camera function information of the slave terminal is received, the master terminal displays the received camera function information of the slave terminal in a display window in step 725. At this time, the user modifies the camera function information of the displayed slave terminal. In operation 727, the master terminal determines whether modification of camera function information of the slave terminal is completed. When the modification of the camera function information is completed, the master terminal transmits a message including the modified camera function information to the server 3 in step 729. In operation 731, the server 3 transmits a message including the modified camera function information to the slave terminal. At this time, the slave terminal resets the camera function according to the modified camera function information received from the server 3.

In operation 733, the master terminal determines whether photography is selected by a user's button manipulation. When the shooting selection is detected, the master terminal transmits a shooting request signal to the server 3 in step 735. In step 737, the server 3 transmits a shooting command signal to the master terminal and the slave terminal. In operation 739, the master terminal receiving the photographing command signal captures a subject according to a camera function currently set. Likewise, the slave terminal captures a subject according to a camera function currently set in step 740.

Thereafter, the master terminal transmits the image data obtained by photographing to the server 3 in step 741, and the slave terminal transmits the image data obtained by photographing to the server 3 in step 743.

In operation 745, the server 3 transmits the image data received from the slave terminal to the master terminal, and transmits the image data from the master terminal to the slave terminal in step 747. As such, a plurality of terminals participating in the shooting may automatically share the taken pictures.

As described above, a terminal registered as a master has a right to control camera functions of terminals registered as slaves. When the camera function setting of the terminals participating in the multi-photography group is completed, the master terminal transmits a shooting request to the server, and the server transmits a shooting command to the terminals. Then, the terminals photograph the subject according to a preset camera function. That is, the present invention can realize a multi-shooting which can photograph one subject from various angles. Moreover, if you take full advantage of the camera's functions (eg continuous shooting, special shooting, etc.), you can shoot your subject in a variety of ways. Meanwhile, since the photographed picture is provided to other terminals in real time through a traffic channel, the photographed picture can be shared and edited in all terminals.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. For example, the present invention can also be implemented as a part of a messenger (eg, MSM messenger) that can confirm a connection. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, the present invention has an advantage of photographing a subject from various angles with only one terminal operation. At this time, the terminal as a reference can control the various camera functions as well as the recording time of the remaining terminals to shoot the subject in a variety of ways. In addition, since the photographed picture is provided to other terminals in real time, the terminals participating in the photographing can easily share and edit the photographed pictures.
