And the image sharing key corresponds to the number of users who want to share the image. In addition, the image sharing key can be added or deleted. For example, the image sharing key is deleted when it is moved a predetermined distance to the left or right by touching or dragging or flicking, and is added in any one direction above or below the currently displayed image sharing key through menu selection.

The image sharing key is set to be automatically deleted when image sharing ends.

The image sharing key is automatically integrated into one multi-image sharing key when the number of all image sharing keys exceeds a predetermined number.

The at least one image sharing key is displayed as one multi-image sharing key by touching and dragging or flicking of the user.

According to an embodiment of the present invention, there is provided a method of sharing a video of a mobile terminal, the method comprising: performing a multi-party call with a plurality of users; Displaying at least one image sharing key associated with a user selected for image sharing among a plurality of users; And a step of performing image sharing with a desired user by selecting a specific image sharing key displayed.

And the image sharing key corresponds to the number of users who want to share the image. In addition, the image sharing key can be added or deleted. For example, the image sharing key is deleted when it is moved a predetermined distance to the left or right by touching or dragging or flicking, and is added in any one direction above or below the currently displayed image sharing key through menu selection.

The image sharing key is set to be automatically deleted when image sharing ends.

The image sharing key is automatically integrated into one multi-image sharing key when the number of all image sharing keys exceeds a predetermined number.

The mobile terminal and its video sharing method according to an embodiment of the present invention provide a convenience for a user by providing a video sharing function not only in one-to-one communication but also in multi-user communication.

The broadcast receiving module 111 receives broadcast signals and / or broadcast-related information from an external broadcast management server through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast management server may refer to a server for generating and transmitting broadcast signals and / or broadcast related information, or a server for receiving broadcast signals and / or broadcast related information generated by the broadcast management server and transmitting the generated broadcast signals and / or broadcast related information. The broadcast-related information may refer to a broadcast channel, a broadcast program, or information related to a broadcast service provider. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and a broadcast signal in which a data broadcast signal is combined with a TV broadcast signal or a radio broadcast signal.

Meanwhile, the broadcast related information may be provided through a mobile communication network, and in this case, it may be received by the mobile communication module 112.

The broadcast-related information may exist in various forms. For example, an EPG (Electronic Program Guide) of DMB (Digital Multimedia Broadcasting) or an ESG (Electronic Service Guide) of Digital Video Broadcast-Handheld (DVB-H).

The broadcast receiving module 111 receives broadcasting signals using various broadcasting systems. In particular, the broadcasting receiving module 111 may be a Digital Multimedia Broadcasting-Terrestrial (DMB-T), a Digital Multimedia Broadcasting-Satellite (DMB-S) Only Digital Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T), and the like. Of course, the broadcast receiving module 111 is configured to be suitable for all broadcasting systems that provide broadcasting signals as well as the digital broadcasting system described above.

The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

In addition, the mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and the wireless Internet module 113 can be built in or externally. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. A typical example of the position information module 115 is a Global Position System (GPS) module. According to the present technology, the GPS module calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain three-dimensional current position information according to latitude, longitude, and altitude It can be calculated accurately. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display module 151.

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

The user input unit 130 generates input data for a user to control the operation of the terminal. The user input unit 130 may include a key pad, a dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. Particularly, when the touch pad has a mutual layer structure with the display module 151 described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence or absence of user contact, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be described later in connection with touch screens.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, Video input / output (I / O) ports, earphone ports, and the like.

Here, the identification module is a chip that stores various information for authenticating the use right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device.

The interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, Various command signals may be transmitted to the mobile terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display module 151, an audio output module 152, and an alarm unit 153.

The display module 151 displays and outputs information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display module 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display module 151 can be used as an input device in addition to the output device. The display module 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent organic light emitting diode (TOLED) or the like. In addition, there may be two or more display modules 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may be provided with an external display module (not shown) and an internal display module (not shown) at the same time. The touch screen may be configured to detect not only the touch input position and area but also the touch input pressure.

Meanwhile, the proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. Therefore, the proximity sensor 141 has a considerably long life span and its utilization is also significantly higher than that of the contact-type sensor.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

An example of the operation of the high-frequency oscillation-type proximity sensor will be described. In a state where a high frequency of a stationary wave is oscillated in an oscillation circuit, when the sensing object approaches the vicinity of the sensor sensing surface, the oscillation amplitude of the oscillation circuit attenuates or stops , And these changes are converted into electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor 141 may be configured so as to detect the proximity of the pointer with the change of the electric field along the proximity of the pointer if the touch screen is electrostatic.

Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; In addition, a position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects proximity touches and proximity touch patterns (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, and the like) , And may output information corresponding to the detected proximity touch operation and the proximity touch pattern on the touch screen.

The audio output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 152 outputs an acoustic signal related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display module 151 or the sound output module 152.

The memory 160 may store a program for processing and controlling the control unit 180 and may store a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, . In addition, the memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read- And may include at least one type of storage medium among the optical discs. Also, the mobile terminal 100 may operate a web storage for performing a storage function of the memory 160 on the Internet.

The control unit 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

The mobile terminal 100 mainly operates in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The mobile terminal 100 operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

The casing (casing, housing, cover, etc.) constituting the outer appearance of the first body 200 is formed by the first front case 220 and the first rear case 225. Various electronic components are installed in a space formed by the first front case 220 and the first rear case 225. At least one intermediate case may be additionally disposed between the first front case 220 and the first rear case 225.

In this case, the word "base station" may be referred to as a combination of one BSC 275 and at least one BS 270. [ The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

4, a broadcasting transmitter (BT) 295 transmits a broadcasting signal to the terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT 295.

In addition, FIG. 4 illustrates several Global Positioning System ('GPS') satellites 300. The satellites 300 help to locate at least one of the plurality of terminals 100. Although two satellites are shown in Figure 4, useful location information may be obtained by two or more satellites. The location information module 115 shown in FIG. 1 cooperates with satellites 300 to obtain desired location information. Here, you can track your location using all of the technologies that can track your location, as well as your GPS tracking technology. Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Among the typical operations of a wireless communication system, the BS 270 receives a reverse link signal from the various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270. The BSC 275 also transmits the received data to the MSC 280 and the MSC 280 provides additional transmission services for connection with the PSTN 290. [ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

The mobile terminal provides a Video Sharing Call (VSC) function that transmits a video image (video signal) stored in a pre-stored image or a camera in a communication mode in which a voice signal is transmitted and received to a correspondent terminal in real time. The user of the mobile terminal establishes a session with a user who wants to share the video and then shares the video through the session. At this time, the user (or sender) who wants to share the image is referred to as MO, and the user (or receiver) who receives the image is referred to as MT.

5 is a signal flow diagram for performing image sharing in a conventional one-to-one call.

5, the user (MO) 50 transmits a session establishment request (INVITE) message to the user (MT) 51 in order to share the image. In the INVITE message, the MO 50 can receive a certain type of image to the user (MT), and the location where the image is to be transmitted can be included. The INVITE message passes through several SIP servers (not shown) in order to be delivered to the MT 50. The SIP server is implemented as a proxy server having only a message forwarding function.

The SIP server that has received the INVITE message parses the INVITE message and recognizes the MT 50, and then transmits the INVITE message to another appropriate SIP server or the MT 51.

The MT 51 receiving the INVIT message sends a response message to the INVITE message. The response message includes a status code indicating a processing result. If the MT 51 successfully receives and processes the INVITE message, it transmits a response message "200 OK" to the MO 50. Upon receiving the response message, the MO 50 transmits an ACK request message again to the MT 51 to notify that the response message (200 OK) sent from the MT 51 has been properly received, One session is created.

Accordingly, the MO 50 transmits to the MT 51 an image to be shared through a set session, for example, a previously stored image or an image (video signal) captured by the camera in real time.

In the present invention, when a video sharing menu is selected during a multi-party call with a plurality of users, at least one video sharing key associated with a user selected for video sharing among a plurality of users is displayed, Select a desired video sharing key to share video with the user.

6 is a signal flow diagram for performing image sharing in a one-to-many call according to an embodiment of the present invention. In the present invention, video sharing in a one-to-many communication is referred to as "multi-party video sharing function"

Referring to FIG. 6, an operation in which a user (MO) 50 transmits a session establishment request (INVITE) message to a user (MT1) 51 to establish a session is the same as in FIG. The MO 50 can perform a voice communication with the MT 51 through the established session (for example, session 1) and can communicate with another user (MT2) 52 during voice communication with the MT 51, (MT2) 52 as shown in FIG. 6, or may request a session setup from the user (MT2) 52 as shown in FIG.

When the INVITE message requesting the session setup is received by the user (MT2) 52, the MO 50 transmits the processing result of the INVITE message to the MT 52, including the response message (200 OK). Upon receiving the response message, the MT 52 transmits an ACK request message again to the MT 50 to notify that the response message (200 OK) sent from the MT 50 has been properly received, One session (e.g., session 2) is created.

Therefore, the MO 50 performs a multi-image sharing function by transmitting the previously stored image or the image photographed by the camera to the MT1 51 and the MT2 52 through the set session 1 and session 2, respectively.

7 is a view illustrating an example of a terminal screen of a user sharing an image when providing a video sharing function in a multi-party call.

As shown in FIG. 7, the user (MO) selects the users MT1 and MT2 from among the multiple calls and performs the multi-party video sharing function. At this time, the user (MO) has the right of video sharing and the information of the current video sharing partner is displayed on the screen of the terminal of the MO.

The information of the other party may be displayed on the right side of the screen 60 or the avatar and on the left side the name 61 of the other party MT1 or MT2 and a telephone number may be displayed. In FIG. 7, the photograph 60, the name of the other party, and the telephone number are all displayed, but may be selectively displayed as necessary

An image sharing execution key 62 (hereinafter abbreviated as a video sharing key) is displayed below the photo 60 and the name 61 of the other party. The image sharing key 62 corresponds to the number of MTs for which the MO wants to share the image. When a session is established between the user MO and the users MT1 and MT2, the control unit 180 displays two video images corresponding to the users MT1 and MT2 on the screen, Key 62 is displayed.

The number of the image sharing keys 62 is the same as the number of users who want to share the image but is not the same as the number of users who perform voice communication. This is because a user (MO) having a video sharing right can transmit an image to only a specific user without transmitting all user (MT) essence images. To this end, the control unit 180 provides a menu for the user to select an image sharing object (MT) and user information.

The number of the image sharing keys 62 should be able to be added or deleted. If a session for voice communication is established between the MO and a plurality of MTs, the control unit 180 generates a video sharing key 62 corresponding to the session through the menu setting, and then transmits a specific video sharing key 62 can be deleted.

For example, the image sharing key 62 can be set to be deleted when moved by a predetermined distance by touching and dragging or flicking. The touching and dragging indicates that the MO user drags the image sharing key 62 to be deleted, leftward or rightward, and flicking also indicates flicking left or right after touching. Preferably, the touch includes both an actual touch or a proximity touch.

In addition, the image sharing key 62 may be added in either the upper or lower direction, and may be automatically deleted when the image sharing ends. In this case, due to the space limitation of the screen, the control unit 180 deletes the specific image sharing key 62 according to the predetermined priority order.

One picture (or avatar), a name and a telephone number are displayed on the screens of the terminals MT1 and MT2, and one image sharing execution key is provided below the screens. Therefore, when the users MT1 and MT2 have the image sharing right, the one-to-one image sharing is performed as in the conventional case.

On the other hand, the video sharing key 62 can be added every time a new session is established. However, since the size of the screen of the user (MO) terminal is limited, when there are a large number of users sharing a video, such as a conference call, all the user's information and video sharing keys are stored in one screen Can not be represented.

In this case, the plurality of image sharing keys 62 may be integrated into one multi-image sharing key. If the plurality of image sharing keys 62 are integrated into one multi-image sharing key, the information of the user (MT) can also be selectively displayed on the screen. For example, the user MT who made the first call may be displayed or a preset user MT may be displayed according to the priority.

One method of integrating the plurality of image sharing keys into one multi-image sharing key is a method using touch-drag or flicking.

That is, the user MO touches and drags or flickes the top or bottom image sharing key 62 to transfer the plurality of image sharing keys 62 to one multi-image sharing key 63 Can be integrated. 8A and 8B show an example of integrating a plurality of image sharing keys into one multi-image sharing key by touch & drag.

Another method of integrating the plurality of image sharing keys into one multi-image sharing key is to allow the user MO to touch the top and bottom image sharing keys 62 with the thumb and index finger, and then bring the two fingers closer to each other . This method is advantageous in that a plurality of image sharing keys 62 can be integrated into one multi-image sharing key 63 precisely.

Another method of integrating the plurality of image sharing keys into one multi-image sharing key is a method of automatically performing integration by the control unit 180. [ Since the control unit 180 controls session setting and image sharing, the control unit 180 can count the number of image sharing keys displayed on the current screen. When a new image sharing key is added and exceeds a predetermined number, the control unit 180 automatically integrates a plurality of image sharing keys into one multi-image sharing key 63.

In addition, the present invention automatically displays the multi-image sharing key 63 on the screen and displays preset user information (MT) when a conference call starts from the beginning.

9, the user MO proceeds with a conference call with a plurality of users MT1 to MT3 and presses the multi-image sharing key 63 during the video conference to transmit a desired image To all users MT1 to MT3 simultaneously.

On the other hand, the integrated multi-image sharing key 63 may be separated into a plurality of image sharing keys 62 by performing the reverse operation.

10 is a flowchart illustrating a video sharing method of a mobile terminal according to an embodiment of the present invention during a multi-party call.

10, the control unit 180 of the user (MO) terminal for sharing an image sets at least one session by transmitting an INVITE message to a plurality of user terminals (MT) .

If a user selects an image sharing menu (not shown) during a multi-party voice call through the established session, the control unit 180 controls the user to share the image (MO), the screen of the display unit 151 (Photo, avatar, name, telephone number,...) To be displayed on the screen (S11). The items are stored in the memory 160 in advance.

7, when the MO user selects a specific item from the menu, the controller 180 displays a plurality of image sharing keys corresponding to the selected user (MO) Avatar, name, phone number) (S12).

Accordingly, the user performs an image sharing function during a multi-party call with a plurality of users (MT) by selecting a pre-stored image or an image photographed by the camera and selecting each image sharing key (S13).

FIG. 11 is a flowchart illustrating an example of integrating a plurality of image sharing keys into one multi-image sharing key when performing the image sharing function in FIG.

11, when a call is established with another user (MT), that is, when a new session is established between the MO and the MT (S20), the controller 180 provides a new image sharing key (S21).

When a new image sharing key is added, the controller 180 integrates the plurality of image sharing keys 62 into one multi-image sharing key, as shown in FIG. 8A, if the number of currently displayed video sharing devices exceeds a predetermined number (S22, S23).

Accordingly, the user selects the pre-stored image or the image photographed by the camera, and then selects the multi-image sharing key 63 so that the selected image is simultaneously transmitted to a plurality of users (S24).

In this way, when performing the image sharing function, the present invention integrates a plurality of image sharing keys into one multi-image sharing key, and simultaneously transmits the desired image to a plurality of users (MTs) at once by operating the integrated multi- .
