The type of the display box includes at least one of color, shape, size, and location information.

An operation of performing pseudo display between each other while displaying a predetermined position of an image through a display box in the video call mode of the portable terminal will be described in detail with reference to FIGS. 2A and 2B.

2A and 2B are flowcharts illustrating a process of displaying a predetermined position of an image through a display box in a video call mode of a mobile terminal according to an exemplary embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1.

Referring to FIG. 2A, when the pseudo display menu is selected in step 201, which is a video call mode through which audio and video data are transmitted and received in the portable terminal, the controller 130 detects the same in step 202. In step 203, the portable terminal switches to the pseudo display mode of the video call mode.

When the image is selected in the pseudo display mode, the controller 130 detects it in step 204 and displays the type of image. When a certain image is selected among the types of the image, the controller 130 detects it and proceeds to step 205 of displaying the selected image in the pseudo display mode.

When the display box is selected while the image is displayed in the pseudo display mode, the control unit 130 detects it in step 206 and displays the display box by overlapping the display box at the default position of the image, for example, the center position of the image. Proceed to step 207.

Alternatively, when the pseudo display menu is selected while a certain image is displayed in the video call mode of step 201, the display box may be overlapped and displayed at a center position which is a basic setting position of the image.

If a color of the display box is selected in a state where the display box is overlapped and displayed at the center position of the image, the controller 130 detects this and displays a color index table. When a predetermined color is selected in the color index table, the controller 130 detects this and controls to display the display box with the selected color.

Alternatively, when the shape of the display box is selected, the controller 130 detects this and displays a shape index table. When a certain shape is selected in the shape index table, the controller 130 detects this and controls to display the display box with the selected shape.

Alternatively, when the size of the display box is selected, the controller 130 detects this and controls the display box to be displayed in the size adjusted by the user.

As described above, the display box may be displayed by overlapping the image with at least one of a color, a shape, and a size selected by the user. Thus, the display box may be displayed separately when displaying at least two display boxes.

When the display box is moved through the input of a direction key while the display box is overlapped with the image in step 207, the controller 130 detects this in step 208 and the image corresponding to the movement of the display box. Control to display the display box at the position of. Alternatively, when the display unit 180 is a touch screen, the controller 130 may control the display box to be displayed at a predetermined position where the display unit 180 is touched.

If confirmation is selected while moving the display box on the image and positioning the display box at the predetermined position, the control unit 130 detects it in step 209 and includes the image and the display box information superimposed on the image. In step 210, the intention information is transmitted.

In step 210, the controller 130 encodes the image, and displays at least one of display box information displayed on a predetermined position of the image, that is, at least one of color, shape, and size information set in the display box. Extract the location information of the box. The controller 130 stores the encoded image and the extracted display box information in a transmission buffer, and transmits the encoded image and the displayed display box information to a counterpart portable terminal to which a video call is connected.

Is transmitted to the n counterpart portable terminals to which the video call is connected.

Through the processes as shown in FIG. 2A, the user of the portable terminal may request or explain an opinion such as a question in real time while displaying a predetermined position of the image as a display box to the user of the mobile terminal connected to the video call.

Then, when the pseudo display information is received from the counterpart portable terminal, the control unit 130 detects it in step 211 and determines the type of the video call mode of the portable terminal.

If the video call mode is a one-to-one video call mode, the control unit 130 detects it in step 212 and displays the pseudo display information received from one mobile terminal connected to the video call on the display unit 180. Proceed.

In step 213, the controller 130 decodes an image included in the received pseudo display information, that is, an image that is commonly displayed in the mobile terminal and the counterpart portable terminal, and is superimposed on the decoded image. Extract display box information.

According to the display box information extraction, the controller 130 controls to display the display box set to at least one of color, shape, and size in the decoded image at a predetermined position of the image according to the location information. In this case, the controller 130 may display the display box selected from the portable terminal and the display box included in the pseudo display information of the counterpart portable terminal by the corresponding number and name as well as the color, shape and size of the display box. Can be.

Alternatively, if the video call mode is a multi-party video call mode, the controller 130 detects this in step 212 and combines the n pseudo display information received from the n counterpart mobile terminals connected to the video call to the display unit 180. Proceed to step 214 for displaying.

In step 214, the controller 130 controls to decode an image included in the received n pseudo display information, that is, one image that is commonly displayed in the mobile terminal and the n counterpart portable terminals. The controller 130 extracts n display box information included in the received n pseudo display information, respectively.

According to the extraction of the n display box information, the controller 130 displays the n display boxes indicating the intentions of the users of the n counterpart portable terminals on the decoded image.

The controller 130 controls to display the n display boxes corresponding to information set to at least one of color, shape, and size information, respectively, in the one image, and also displays the n display boxes according to the corresponding location information. Control to display at n constant positions. In this case, the control unit 130 distinguishes the display box selected from the portable terminal with the number, name, etc. of the display box and the n display boxes included in the pseudo display information of the n counterpart portable terminals. Can be displayed together.

In step 214, the controller 130 may display the n pseudo display information received from the n counterpart portable terminals for a predetermined time and then combine them. In addition, the controller 130 may combine and display n pseudo display information received from the n counterpart portable terminals.
