Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration of a mobile terminal for providing a mobile video telephone service to which the present invention is applied.

Since the mobile terminal providing the mobile video telephone service to which the present invention is applied is merely a technique well known in the art, detailed description thereof will be omitted herein. However, in order to transmit various video signals desired by the caller, the mounting of the camera will be described in more detail with respect to the video signal input unit 10 capable of 360-degree rotation of the projection.

The mobile terminal providing a mobile video call service to which the present invention is applied, in mounting a camera that is a video signal input unit 10, switches the camera outside the function of the camera not to be completely fixed in order to provide a variety of images desired by the caller. Mounted in a way to protrude to the outside by the 50, the protruding camera is implemented in a way that can be rotated 360 degrees to enable the image input of the entire surrounding. 2 illustrates a mobile terminal for providing a mobile video telephone service when the video signal input unit 10 protrudes.

2 is an exemplary configuration diagram of a mobile terminal for providing a mobile video telephone service when the video signal input unit is applied according to the present invention.

When the user who wants the video service turns the camera external protrusion function switch 50 ON, the camera which is the video signal input unit 10 protrudes to the upper portion of the terminal.

Accordingly, the user may rotate the camera 10 while watching the screen displayed on the video signal output unit 20 to adjust the input of the desired video signal.

3 is a flowchart illustrating an operation method of a terminal for providing a video telephone service according to the present invention, and shows the operation and call setup procedure of a terminal, particularly a mobile terminal, shown at the time of origination.

In this embodiment, the mobile video terminal has both a voice call and a video call setup, and when the user wants the video service, the user opens the terminal, and then the camera which is the video signal input unit 10 protrudes out of the camera. Protrude by using the switch 50 so that the desired video is input to dial the number of the called party to the call, if you do not want the video service only if you want to receive a voice service, do not drive the camera 10 after opening the terminal Try dialing without At this time, the terminal automatically sets a video call and a voice call according to the user's operation.

And, in the present embodiment, the user is holding the terminal in his hand during the video call and looking at the screen, and during the voice call, the voice signal output of the speaker, which is the voice signal output unit 40, is automatically connected to the user. To control.

In addition, the present embodiment allows the user to distinguish between the incoming and outgoing ringtones for the voice call and the video call in two different ways.

As shown in Figure 3, the operation method of the terminal for providing a video call service according to the present invention, first, when the calling user who wants to make a phone call (Open) the terminal (301), the terminal is ready to call In step 302, input from the user is analyzed (303).

As a result of the analysis, when the On signal of the camera external protrusion function switch 50 is received from the calling user who wants the video service, the terminal automatically detects that the user wants the video service and prepares to set up the video call (304). ). That is, the terminal protrudes the image signal input unit (camera) 10 to the outside, and displays the image currently being input to the image output unit (screen) 20 of the terminal to confirm the image data to be transmitted to the user. . In this case, the user adjusts the image to be transmitted while rotating the camera to transmit the desired image (305).

Then, when the camera is adjusted so that the desired image is transmitted, the terminal dials the called party's telephone number received from the user through the keypad 60 for dialing and additional function control and attempts to make a call (306).

Next, since the terminal has automatically sensed to set the video call when the user projects the camera, the terminal attempts to call the current call (307) and checks whether the video call is set correctly (308).

As a result of the inspection, if the video call is correctly set (that is, the video call attempt is successful), the terminal controls the audio output of the audio signal output unit (speaker) 40 so that the user can hold the terminal and make a call (309). The called party's video signal is output in the call state (310). At this time, when the called user starts the call by driving the video signal input unit (camera) 10, the terminal automatically outputs the voice of the called party through the voice signal output unit (speaker) 40 (309). The side image is displayed on the video signal output unit (screen) 20 (310). On the other hand, if the called user does not drive the video signal input unit (camera) 10, the terminal automatically outputs only the voice of the incoming caller through the audio signal output unit (speaker) 40 (309) and the video signal output unit No image is displayed on the screen 20. If the called user drives the camera at any time during a call, the called image is displayed on the video signal output unit (screen) 20 (310).

As a result of the inspection, if the video call attempt fails, it is determined whether the video call attempt is within the range of the video call retry count n (311).

As a result of the determination, if the video call attempt is within the video call retry count (n), after retrying the video call within the video call retry count (n) (307), it is checked whether the video call is set correctly (308). If the video call retry count is out of n, the video call retry is terminated and the user is informed that the current video call cannot be set (312).

As a result, when the called party's telephone number dialed through the keypad 60 for dialing and additional function control is received from the user, the terminal automatically detects it as a voice call and attempts to make the current call a voice call (313). Check if it is (314).

As a result of the test, if the voice call is correctly set (i.e., the voice call attempt is successful), the terminal controls the voice output of the voice signal output unit (speaker) 40 so that the user can make a call with the terminal on his ear (315). Like the terminal, the voice signal input unit (microphone) 30 is put in the mouth and the voice signal output unit (speaker) 40 is put in the voice call state so as to be able to make a call (316). In addition, the terminal allows the user to make a voice call using the speakerphone mode according to a request input through the keypad 60 for dialing additional function control from the user.

As a result of the check, if the voice call attempt fails, it is determined whether the voice call attempt is within the range of the voice call retry count m (317).

As a result of the determination, if the voice call attempt is within the range of the voice call retry count (m), after continuing to retry the voice call within the range of the voice call retry count (m) (313), it is checked whether the voice call is set correctly (314). If the voice call retry count (m) is out, the voice call retry is terminated and the user is notified that the current voice call cannot be set (318).

On the other hand, in the case of the called user, in order to be able to distinguish whether the incoming call is a video call or an audio call, the terminal provides a function of differently selecting a ringing tone of the video call and the audio call. Therefore, the user adjusts the dialing and additional function control keypad 60 to set the ringing tone desired by the user differently, and the terminal rings the ringing tone set by the user according to the call.

Therefore, the called user calls the terminal with his / her ear when a voice call is received, and opens the terminal when the video call is received, and then uses the camera external protrusion function switch 50 to input the video signal input unit (camera) 10. Protrude) to conduct a two-way video call with the other party. In this case, the call can be made even if the user does not protrude the video signal input unit (camera) 10. Here, the video call is set, but only voice data is transmitted.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention enables the terminal to provide both a voice call and a video call at the time of providing a video call service, so that the user can select it for each call, so that only the voice call is desired, not the video call. In this case, it is possible to reduce power consumption of the terminal and to provide a more inexpensive service to the user by using resources efficiently. In addition, the present invention can increase the user's convenience by automatically setting the call to determine whether the user's desired call is a voice call or a video call according to whether the user's camera is driven when the video call service is provided.

In addition, the present invention, when the user wants a video phone service, the user can make a phone call in hand, and when only a voice service can be called to the ear as with the existing terminal, the control of the audio output for this function Can be made automatically when the camera is driven without the user's separate operation, thereby increasing the user's convenience. In addition, the present invention, by allowing the user of the camera of the terminal to be used more conveniently and effectively, the user can easily transmit the desired video signal, and the calling user can meet the needs of the user by checking the image to be transmitted It has an effect.
