As shown, the present invention is a base station (Node B, 210, 210 ') and the control station (RNC, 220, 220') for the first terminal 100 and the second terminal (100 ') for transmitting and receiving a wireless section signal A MSC server (MSV) for video call control, a media gateway (MGW) responsible for resource management and resource control, and a switch (MSC, 230, 230 ') that provides a video call path, subscriber location information and additions. A video call system including a home location register 240 that manages service information may be used to perform a virtual action on a counterpart's face image during a video call.

In the present invention, the virtual action (contact) refers to a counterpart image displayed on the counterpart terminal when a specific position is designated in the counterpart's image displayed on the screen and an action type such as pinching, pressing, pulling, or graffiti is selected. By the selected action, the ball portion of the face is stretched in a specific direction, the hair is moved, or the complexion is changed to be displayed.

In the embodiment of FIG. 2, when a doodle action is selected among the types of virtual actions, an action pointer (pointing tool such as a pen or a pencil) for doodle is selected as the user of the first terminal 100 selects a doodle. When the pointer is displayed on the screen of the first terminal 100 and the pointer is moved from the other image through the direction key button or touch (in the case of a touch screen), the contact position coordinates (pointer coordinates) and the action code are displayed in real time on the second terminal 100. ') Is sent.

Then, the second terminal 100 ′ receiving the insertion inserts the pointing tool image file according to the action code in its own image, transforms the image of the own terminal, and displays the modified image. It is desirable for the image to be deformed in such a way that it is drawn.

On the other hand, in case of an action such as pinching, pressing, or pulling, once the action type is selected, the pointer position coordinate and the action code of the corresponding point of time are preferably transmitted once, but in the case of the graffiti action, the path for moving the pointer It is preferable that the position coordinate of is continuously transmitted to the counterpart terminal so that a line is drawn along the movement path of the pointer in the counterpart terminal.

As a user of the first terminal 100 selects a pinch action, a pinch action pointer (hand image) is displayed on the screen, and a direction key button or a touch is displayed. When the pointer is placed at a specific point of the other party's image through the touch screen, execution is requested, and the contact position coordinates (pointer coordinates) and the action code are transmitted to the second terminal 100 '.

Upon receiving this, the second terminal 100 ′ inserts a hand-shaped image file among the image files of the pointing tool according to the action code, and deforms and displays its own image. In the case of the pinch action, the image may be deformed in such a manner that the complexion of the pinched part turns red as the face is stretched in a certain direction.

Next, a configuration of the mobile communication terminal for the virtual action service of the present invention described with reference to FIGS. 2 and 3 will be described with reference to FIG. 4.

As shown in FIG. 4, the mobile communication terminal 100 of the present invention includes a wireless transceiver 110 for transmitting and receiving wireless signals with a base station, an input unit 120 for outputting corresponding data according to a user input, and various A memory 130 for storing data, a display unit 140 for receiving and displaying key data and various information signals generated from the input unit 120, and an audio unit for processing voice signals input and output through a speaker and a microphone ( 150, and includes a camera unit 160 for image processing, and further includes a virtual contact module 160 for a virtual action of the present invention.

The virtual contact module 170 is driven at the user's request or by the user's response to the request from the counterpart terminal, and outputs a menu or icon for selecting an action type on the screen, Modifying the other party's image according to the request, or modifying the own image according to the request of the other party, and for this purpose, the own image display unit 171, the pointer processing unit 172, the action code transmitting unit 173, The image deformer 174 is included.

When the pointer coordinates and the action code are received from the counterpart terminal in the video call, the own image display unit 171 divides the screen on which the counterpart image is displayed and displays the counterpart image and its own image.

If the terminal is implemented such that both the video of the counterpart and the video of the other are displayed on the screen during the video call, the own video display unit 171 may be omitted. Otherwise, the virtual contact module 170 is driven. As a result, the own image display unit 171 divides the screen and displays its own image.

When a user input for virtual contact occurs during a video call, the pointer processor 172 displays a pointer for displaying a contact location on a video call counterpart image displayed on a screen, and moves the position of the pointer according to a user's input. If the action is requested to be executed at a specific position, the coordinates of the current pointer are transmitted to the action code transmitter 173. If the selected action type is graffiti, the moving position coordinates should be transmitted to the action code transmitter 173 in real time.

Meanwhile, the virtual action of the present invention may be performed under the permission of the other party. To this end, when the user input for the virtual contact is generated, the pointer processing unit 172 transmits a message inquiring whether to allow the virtual contact to the counterpart terminal. If it is determined that the virtual contact is allowed, the pointer display and the pointer position movement may be executed based on the virtual contact permission response message received from the counterpart terminal.

When the action type is selected by the user, the action code transmission unit 173 sends a 3G-324M data logic channel or control logic channel (control channel) based on the coordinates of the pointer located on the counterpart image and the action code according to the selected action type. Send to the other terminal in the video call through.

When the Scribble action is selected, a color palette can be displayed on the screen so that the user can select the color of the pen to be scribble. In this case, the action code transmitter 173 includes the selected color information (RGB) along with the action code and the pointer coordinates. Value) so that a line of the selected color can be drawn on the user image.

The image transformation unit 174 is a block for transforming an image of a point selected by a user according to a selected action. The image transformation unit 174 stores information on an image transformation method for each action code and a pointing tool image file to be inserted, and corresponds to a pointer coordinate. Determines a point, transforms the image by applying an effect corresponding to the action code to the determined point, and at the same time a hand tool or a pen-like pointing tool image file at a point corresponding to the pointer coordinates of the deformed image. Insert it and display it on the screen.

Here, the inserted pointing tool image file may be a video about a pinching operation, a pulling operation, or the like. In the case of the graffiti action, the pointing tool may be moved along a moving path.

In the action requester terminal, the image transformation unit 174 transforms a point where the pointer is located in the counterpart image displayed on the screen in a manner corresponding to an action code according to the action type selected by the user, and displays the coordinate on the screen. The terminal receiving the action code performs an operation of transforming an image of a point corresponding to the corresponding pointer coordinate in its own image displayed on the screen in a manner corresponding to the received action code.

Next, FIGS. 5 and 6 are flowcharts sequentially illustrating a virtual action service method according to an embodiment of the present invention, in which FIG. 5 illustrates an embodiment of an action such as pinching and pulling, and FIG. An example is shown.

As shown in FIG. 5, while a video call path is established between the first terminal and the second terminal (S401), a user of the first terminal presses a virtual contact button or selects a menu. When requesting the execution of the virtual contact module by the method (S402), the first terminal transmits a message inquiring whether to allow the virtual contact to the second terminal (S403), according to the user input of the second terminal, the second terminal When transmitting the virtual contact permission response message to the first terminal (S404), the first terminal based on the virtual contact permission response message, if it is determined that the virtual contact is allowed after driving the virtual contact module 170 (S405) The pointer display and the pointer position movement to the counterpart image displayed on the screen are executed (S406).

Next, when the action code is selected while the pointer is in a specific position (S407), the first terminal transmits the position coordinates and the action code of the pointer to the second terminal (S408), and the received second terminal is displayed on the screen. In addition to inserting the designated pointing tool image file according to the action code into the displayed own image, the image of the user is transformed and displayed in a manner specified for the corresponding action code (S409). If the user's image is not displayed on the screen, the second terminal first divides the screen to display both the counterpart image and its own image, and then transforms the image.

For example, when the twist is selected, a twist effect is applied to the spot when the pinch is selected, and the face color of the spot is changed to red so that the complexion appears to be changed by the pinch. It is possible to insert a hand-shaped image file (video) to be displayed as pinched by. In addition, when the pull is selected, the image may be deformed by applying an effect of extending the corresponding point in a specific direction. And, in case of pressing, the image is transformed to show the face part of the designated position to enter the center of the screen, and the video of the pressing hand shape may be inserted in parallel, and in the case of stroking, the hand-shaped video of the stroking motion without deformation of the face Only insertion can be performed.

In this case, the first terminal may also enable the user to check how the counterpart image is deformed. For this purpose, the first terminal also transmits the pointer coordinates and the action code to the counterpart terminal and is displayed on the screen. The image of the user of the second terminal is transformed according to the action type selected by the user and displayed on the screen (S409 ').

Meanwhile, in the drawing, the action code selection process S406 is performed after the pointer process S405, but the action code may be selected first, and then the pointer operation may be performed.

Next, FIG. 6 illustrates an example in which a graffiti action is selected, wherein a video call path is established between a first terminal and a second terminal and a video call is performed (S501). When requesting the execution of the virtual contact module by pressing or selecting a menu (S502), the first terminal transmits a message for inquiring whether to allow virtual contact to the second terminal (S503).

In response to the user input of the second terminal, when the second terminal transmits a virtual contact permission response message to the first terminal (S504), the first terminal may be configured to perform virtual contact based on the virtual contact permission response message. If it is determined to be allowed to drive the virtual contact module (S505).

Next, when the graffiti action code is selected from the user (S506), the first terminal displays a graffiti pointer (a writing tool such as a pen or a pencil) on the counterpart image, and executes the pointer position movement according to the user's direction key input (S506). At the same time, the coordinates and action code of the graffiti pointer are continuously transmitted to the second terminal in real time (S508). If the color is selected by the user of the first terminal, color information is additionally transmitted to the second terminal.

Accordingly, the second terminal determines a point corresponding to the pointer coordinates in the user image, and deforms the image by applying an effect (doodle) corresponding to the action code to the determined point (S509). Since the graffiti action is to make the face appear to be graffitied by the other party, the second terminal inserts an image file shaped like a writing tool among the pointing tools at a point corresponding to the pointer coordinates, and then receives the coordinates received in real time. You can transform the image by drawing a line.

In addition, the first terminal performs image transformation by graffiti on the counterpart image displayed on the screen in real time according to the movement of the pointer (S509 ').
