2 is a diagram illustrating a method of transmitting search information during a video call service in a mobile terminal according to an embodiment of the present invention, and FIGS. 3A to 3C are diagrams illustrating a video call service performed in a mobile terminal according to an embodiment of the present invention. Is a diagram illustrating an example of a screen for searching for a phone number and transmitting it.

Referring to FIG. 2, first, in step S201, when a user requests a search for any information from the user as in step S203 while performing a video call service with an arbitrary counterpart mobile terminal, the controller proceeds to step S205. An exemplary embodiment of the screen according to the video call service is performed in step S201.

As shown in FIG. 3A, the controller may display the user image data screen 310 of the counterpart mobile terminal received through the RF unit and the user image data screen 320 transmitted through the camera module according to the performance of the video call service. have. The display form of the user image data screens 310 and 320 is not limited thereto and may be displayed in various combinations, and may display any one image data screen according to a setting method, or another image or video desired by the user. Of course, it is also possible to display data such as.

Next, in step S205, the control unit searches for the corresponding information requested by the user in step S203. For example, the phone number requested by the user is searched from the phone book data stored in the memory unit. A screen embodiment thereof is shown in FIG. 3B. In FIG. 3B, a case where the information search is a phone number search will be described.

Referring to FIGS. 3A and 3B, if a phone number search is requested based on an input / selection signal for a phone number search menu while performing the video call service shown in FIG. 3A, the controller returns to FIG. 3B. Displays the phone number search screen. In this case, the phone number search screen may be displayed in an overlay form on the screen of FIG. 3A according to the video call service. The user can search for a desired phone number in the search field as indicated by reference numeral 330 according to an input / selection procedure such as a phone number input or a phone number search based on a menu selection method.

Next, when the requested information is found in step S205, the controller proceeds to step S207 to display a search result screen of the search information. For example, the search result screen of the corresponding phone number requested by the user may be displayed in an overlay form on the screen of FIG. 3A. A screen embodiment thereof is shown in FIG. 3C. 3B and 3C, when the controller first searches for corresponding information input / selected from the user in FIG. 3B, the search screen of FIG. 3B is returned to the search result screen 340 as shown in FIG. 3C. You can switch to display. 3C illustrates an example of a search result screen when a user searches for a telephone number of ABC.

Next, the controller may determine a request signal input from the user after displaying the search result screen in step S207 and perform an operation corresponding thereto. For example, the controller proceeds to step S213 when the user is requested to transmit the search result as shown in step S209 after displaying the search result screen in step S207. In addition, as shown in step S211 after the display of the search result screen in step S207, the controller proceeds to step S219 when the user requests cancellation of the information search.

When transmission of the search result is requested in step S209, the controller generates transmission data for transmission of the search result based on the transmission request method or a preset method in step S213. In detail, in step S213, when the transmission of the search result is requested, the controller may capture the search result screen 340 and generate the image data. As another example, when the transmission of the search result is requested in step S213, the controller may convert the contents of the search result screen 340 into a text form and generate a text file. As another example, in step S213, when the transmission of the search result is requested, the controller may convert the contents of the search result screen 340 into a text form and generate a text message.

Next, when the generation of the transmission data is completed in step S213, the controller proceeds to step S215 and transmits the generated transmission data to the counterpart mobile terminal performing the video call service. In this case, when the transmission data is being transmitted, the search result screen of FIG. 3C is displayed in the form of an overlay until a confirmation event occurs on the screen of the video call service of FIG. 3A to indicate that the search information is being transmitted. desirable.

Meanwhile, in steps S209, S213, and S215, an example in which transmission data is generated and transmitted according to a transmission request method or a setting method when a search result transmission of a user is requested has been described. However, in the present invention, after capturing the search result screen based on the user's capture command in the search result screen display state, the capturing data may be generated, and the capturing data may be transmitted when the user inputs a transmission request. . In addition, the contents of the search result screen is converted into text based on a command for generating a text message of the user in the search result screen display state, and the text message is generated as a text message, and then the text message is transmitted when the user inputs a transmission request. Can be. In this case, preferably, the generated capture data or text message is temporarily stored in the memory unit at the time of its creation, and the captured data or text message to be temporarily stored is transmitted during a transfer command.

Next, the controller determines whether a confirmation event occurs as shown in step S217 during the transmission of data in step S215. In step S217, the confirmation event includes a response signal indicating that transmission data is received from the mobile terminal of the other party performing the video call service, and when receiving the response signal, the controller determines that the confirmation event has occurred. In addition, the confirmation event includes a transmission completion event of the transmission data, and thus, when the transmission of the transmission data is completed, the controller determines that the confirmation event occurs. In addition, the confirmation event includes a screen switching event of the user during the transmission of the transmission data, and when the screen switching is requested from the user during transmission of the transmission data, the controller determines that a confirmation event occurs. In addition, the confirmation event includes a cancellation event for the user to stop transmission of the transmission data, and when such a cancellation event occurs, the controller determines that a confirmation event occurs.

Next, when the controller determines the occurrence of the confirmation event in step S217, the controller proceeds to step S219 to switch the screen to the image screen according to the video call service as shown in FIG. 3A, and then proceeds to step S221. Continue performing video call service.
