The present invention relates to a mobile communication terminal. In particular, in a mobile communication terminal capable of making a video call with an external or built-in digital camera capable of capturing still images or moving images, a caller or a background image stored in the mobile communication terminal during a video call is used. By combining the background image linked to the receiver's phone number with the user's image taken by the current digital camera, and transmitting it to the other party (the calling party or the receiving party), the other party does not need to connect to the screen processing server linked to the mobile communication network. The present invention relates to a method and an apparatus for transmitting a background screen in a video callable mobile communication terminal which enables a video call to be made without changing a background screen around a user according to the user's location.

A method of switching a background screen in a mobile communication terminal capable of a conventional video call is described in Korean Patent Laid-Open Publication No. 2002-60375 (published date: July 18, 2002), and a system using the same as shown in FIG. A mobile communication terminal 10a to 10n connected to the mobile communication network 11 to make a video call with the called party and to transmit and receive various information between the caller and the called party; A screen information database 13 for storing wallpaper information suitable for various situations for each member; Each member has the information on the background screen of the selected video call, and as a request for a phone call to any member is made through the mobile communication network, the member selects the background image and the image of the member. And a screen processing server 12 for transmitting the video call to the mobile terminal capable of making a video call through the mobile communication network.

Herein, the mobile communication terminals 10a to 10n may be connected to other communication networks (for example, the Internet network) through the mobile communication network 11, as well as voice and video through the mobile communication network 11 or other communication networks. And transmission and reception of multimedia is also possible.

The contextual background information stored in the screen information database 13 may be, for example, information about an internal screen of an office where a member works, an external or internal screen of a house where the member lives, and a school screen. The contextual background information consists of various contextual backgrounds input by each member.

First, a user who uses the video communication mobile communication terminals 10a to 10n connects to the mobile communication network 11 and then to the screen processing server 12 connected to the mobile communication network 11, and the background during the video call. In order to support the service that can switch to the background screen that has been set in advance, a member must be registered. In this case, the user who is registered as a member has his or her personal information (for example, name, address, age, etc.) and terminal information ( For example, you can enter a terminal phone number (MIN), a terminal unique number (ESN), etc., as well as a background screen for all situations where the situation can be set (e.g., office, home, school, playground, etc.) It registers with the processing server 12.

The screen processing server 12 may include personal information (for example, name, age, address, etc.) and terminal information (for example, a terminal telephone number (MIN) and a terminal unique number) of each user to which the member subscribes. ESN), etc.), and then grasping which of the various contextual backgrounds stored in the screen information database 13 is a background screen selected by the member, and then calling the member later when the member is called. The background screen serves to be displayed as a background screen on a display panel (not shown) of the mobile communication terminal 10a to 10n of the member.

Further, the screen processing server 12 blurs the background screen when displaying the selected background screen as a background screen on the display panel of the mobile communication terminal 10a to 10n of the member. The image of the member may be combined with the blurred background screen.

Therefore, the conventional technology as described above, after storing the information on the background screen during the video call selected for each member in the screen processing server 12 linked with the mobile communication network 11, the arbitrary information through the mobile communication network (11) As a request for a phone call to a member of the service is requested, a member of the called party is searched by the terminal information of the stored members, and then the selected image of the corresponding member and the image of the member are synthesized to move the synthesized image. By transmitting to the mobile communication terminals 10a to 10n capable of making video calls through the communication network 11, it is possible to make a video call with the other party without exposing his / her current position.

However, in the conventional technology as described above, when the user performs a video call without exposing his or her position by changing the background screen during the video call using a mobile communication terminal capable of video call, the background screen It is inconvenient because the user needs to connect to the mobile communication network every time the user wants to change the background screen because it is necessary to link the mobile communication network with a separate configuration such as a screen processing server and a screen information database. There was a problem that the communication fee increases.

In addition, the number of wallpapers provided by the service provider operating the screen processing server and the screen information database is limited, and the wallpaper is not changed according to the caller, but the wallpaper registered by the user is the same for the caller regardless of the caller. As a result, not only a user's own unique wallpaper can be configured, but also there is a problem in that the sender recognizes the user to deceive herself due to the transmission of the same wallpaper.

Accordingly, the present invention has been proposed to solve the above-mentioned problems. In the mobile communication terminal capable of making a video call with an external or built-in digital camera capable of capturing still images or moving images, Among the stored backgrounds, the background image linked to the calling or receiving phone number is combined with the user image photographed by the current digital camera and transmitted to the other party (sending or receiving side) user. It is an object of the present invention to provide a method of enabling a video call to be performed without exposing a user's location by changing a background screen around a user according to a counterpart without needing to be connected.

The present invention for achieving the above object comprises the steps of storing the background wallpaper data linked to the other party's phone number in the background storage unit of the mobile communication terminal or the default background data set by the terminal user (Default); Extracting a calling party's telephone number using a CID (Caller IDentity) service in a terminal main controller when a call connection request for a video call is received from a called party (sending party); Searching for a background image pre-stored in the background storage unit by using the calling party number and checking whether a background image linked to the calling party number exists; As a result of the check, if there is a background screen linked to the calling party's phone number, the user image captured by the current image sensor is combined with the background picture linked to the calling party's phone number, and then transmitted to the other party (calling party). A method for transmitting a background screen in a video callable mobile communication terminal including performing a video call may be implemented.
The present invention provides a method for storing a background image data linked to a phone number of a counterpart or a background image data set as a default by a terminal user; Confirming a receiving telephone number input through a keypad when the terminal user attempts to connect a call for a video call with a counterpart (receiving side); Searching for a background image pre-stored in the background storage unit by using the receiving side phone number and checking whether a background image linked to the receiving side telephone number exists; As a result of the checking, if there is a background screen linked to the receiving phone number, the user image currently captured by the image sensor is synthesized with the background screen linked to the receiving phone number, and then transmitted to the other party (receiving side). A method for transmitting a background screen in a video callable mobile communication terminal including performing a video call may be implemented.

The present invention can be applied to a mobile communication terminal capable of making a video call with an external or built-in digital camera capable of capturing still images or moving images. When the present invention is applied, it is not necessary to access a screen processing server linked to a mobile communication network. By combining the background image pre-stored in the mobile communication terminal with the image of the user photographed using the digital camera and transmitting the image to the counterpart user according to the calling or receiving phone number, the background image around the user is changed during the video call. It is possible to perform a video call without exposing the to.

The wireless transceiver 20 transmits and receives a radio frequency (RF) signal for performing a video call from a base station in a mobile communication network, and the image sensor 21 is a charge-coupled CCD built in or external to the corresponding mobile communication terminal. Device or CMOS (Complementary Metal-Oxide-Semiconductor) type digital camera, which is activated under the control of the main control unit 25 during a video call and converts an optical signal into an electrical signal by capturing a user's image as a still image or a video. do.

The image processing unit 22 converts the electrical signal photographed by the image sensor 21 into a still image or video data by converting or compressing the electrical signal, and the image sensor ( 21 is taken to process the process and stores the background data in the background storage unit 23 as the background data.

Here, the wallpaper data stored in the wallpaper storage unit 23 is a still image or video data captured by a user or a still image or video data downloaded from a service provider. The still image or video data is converted into wallpaper data. In this case, the wallpaper data is set as a default and stored as the default wallpaper regardless of the calling party or the calling party's telephone number, or a wallpaper for a specific counterpart according to the calling party or the receiving party's telephone number. You can also set it in advance and save different wallpaper according to your opponent.

In addition, the background image synthesizing unit 24 controls a specific background image pre-stored in the background image storage unit 23 and a user image photographed using the image sensor 21 under the control of the main controller 25 during a video call. It serves to synthesize.

In addition, the main control unit 25 sets up a voice call or a data call and executes various application programs to perform overall control of the corresponding mobile communication terminal, and the image processing unit 22 displays a video photographed by the image sensor 21. To control the transmission through the wireless transceiver 20, and in particular, if the user wants to perform a video call without exposing his or her location by changing the surrounding background image, the background image storage unit 23 If there is a background image linked to the calling party number or the receiving party number which is the other party's phone number by searching the stored background data, the background image linking unit 24 controls the background linked to the calling party or the receiving party number. It plays a role of synthesizing the user image captured by the screen and the image sensor 21 and transmitting it to the counterpart.

That is, the main control unit 25 extracts the calling party number transmitted to the wireless transceiver 20 through the CID (Caller Identity) service when there is a call connection request from the other party (calling party) during the video call and then stores the wallpaper. Search the unit 23 to synthesize the background image linked to the calling party's telephone number and the user image captured by the image sensor 21, or when the user attempts to connect a call to any other party (receiving side). After confirming the receiving party's phone number input through the unit (not shown), the background storage unit 23 is searched to synthesize the background image linked to the receiving party's phone number and the user's image captured by the image sensor 21. Each part 20 to 24 is controlled to transmit to the counterpart.

On the other hand, Figure 3 is a flow chart showing the operation of the background screen transmission method in the video communication mobile communication terminal of the present invention, the step of storing the background data in the background storage unit 23 in the mobile communication terminal (S30) and ; If a call connection request for a video call is received through the wireless transceiver 20, extracting the calling party's telephone number using a Caller IDentity (CID) service (S31, S32); Searching for a background image stored in the background storage unit 23 and checking whether there is a background image linked to the extracted calling party number (S33, S34); As a result of the checking, if there is a linked background screen, the user image is input through the image sensor 21 and the background image combining unit 24 synthesizes and transmits the background image and the user image, otherwise the user image is transmitted as it is. Steps S35 to S37; In step S31, when the user attempts to make a call for a video call, checking the receiving telephone number input through the keypad unit (not shown) and performing the processes S33 to S37 (S38). , S39).

The present invention can be divided into a case in which a user receives a call connection request from the other side (calling side) and a call connection attempt from the other side (receiving side) during a video call. Synthesize and send the background image linked to the number to the currently captured user image, or transmit the composite background image set as default to the currently captured user image regardless of the calling party number or the receiving party number. Or transmit the user image captured by the current image sensor 21 as it is.

That is, in case of a video call, image data obtained by synthesizing a user image generated as a video on a background image fixed as a still image or a video is transmitted to the other side. In the case of voice, a sound received from the outside of the current mobile communication terminal It is combined with the video data as it is and sent to the other side.

In addition, for this purpose, the background image storage unit 23 in the mobile communication terminal should store the still image or video data captured by the user or the data downloaded from the service provider as the background image (S30).

First, when a user receives a call connection request, when a call connection request for a video call is received through the wireless transceiver 20 of the mobile communication terminal (S31), the wireless transceiver 20 The calling party number is extracted from the call connection request message received from the base station by using a caller IDentity (CID) service and reported to the main control unit 25 (S32).

Then, the main control unit 25 searches for the background screen previously stored in the background storage unit 23 by using the extracted calling party number (S33), and the background screen linked to the extracted calling party number. Check whether there exists (S34).

As a result of the check, if there is a background screen linked to the calling party's telephone number, the background image composition processing unit 24 is present through the image sensor 21 and the image processing unit 22 under the control of the main control unit 25.

On the other hand, if there is no background screen linked to the calling party's telephone number, the main control unit 25 is the wireless image transmitting and receiving unit 20 as it is the user image currently taken through the image sensor 21 and the image processor 22 as it is. Video call is performed by transmitting to the other party (calling party) through S37. At this time, a default background screen set as a default according to the user's setting may be set as a background screen and may be set to be combined with the user image and transmitted.

On the other hand, when the user attempts to connect the call to the other side (receiving side) for the video call (S38), the main control unit 25 in the mobile communication terminal is input by the user through the keypad unit (not shown) for the video call After confirming the receiving telephone number (S39), as in the operation process (S33 ~ S37) when the call connection request is received by searching the wallpaper stored in the background storage unit 23 (S33), the reception Search whether there is a wallpaper linked to the telephone number on the side (S34), and if there is a wallpaper linked to the receiver's telephone number, the background screen synthesizer 24 is controlled to control the background screen linked to the receiver's telephone number. And synthesize the user image photographed by the current image sensor 21 and the image processor 22, and then transmit the synthesized image to the counterpart (receive side) through the wireless transceiver 20 to perform a video call (S35, S36).

In this case, when there is no background screen linked to the receiving telephone number, the main controller 25 similarly transmits and receives the user image captured by the current image sensor 21 and the image processor 22 as it is. The call is transmitted to the other party (receiving side) through (S37). At this time, it is also possible to combine the user's image with the default background screen set as a default wallpaper according to the user's setting.

As described above, the present invention provides a mobile communication terminal capable of making a video call with an external or built-in digital camera capable of capturing still images or moving images. By combining the background image linked to the phone number with the user's image taken by the current digital camera, and sending it to the other party (the calling party or the receiving party), there is no need to access a separate screen processing server for the video call. It is possible to perform a video call without exposing its own location by changing the background screen, thereby reducing the communication cost according to the connection of the screen processing server and editing and transmitting various types of background images according to the video call counterpart. .
