The shared image 143 can be selected not only by a user of the mobile terminal 1, but also by a user of the duplicated mobile terminal 2. More specifically, the mobile terminal 1 transmits to the duplicated mobile terminal 2 the information of the shared image 143 from the receiving a request to select the shared image 143 from the duplicated mobile terminal 2. A user of the duplicated mobile terminal 2 selects an image to be shared based on the information in the shared image 143, and transmits to the mobile terminal 1 a result of the selected selection. shared image 143. The mobile terminal 1 displays on the display unit 14 the shared image 143 according to the result of selection from the duplicated mobile terminal 2.
    [00051] As shown in Figure 6, the shared image 143 according to the present embodiment is displayed on the display unit 14 together with the video 141 of the video call. Consequently, a user can directly view the shared image 143 during a video call, and can share the information more conveniently.
    [00052] In step 302, the controller 18 of the mobile terminal 1 can edit the shared image 143 during a video call. The shared image 143 according to the present embodiment can be edited by a user input through the user input unit 16, and can be provided as various types related to the shared image 143. For example, the editing of the shared image 143 includes add an image indicating a user gesture to the shared image 143 (then "gesture image" 144) as shown in Figure 6. The controller 18 of the mobile terminal 1 displays on the display unit 14 the gesture image 144 superimposed on the shared image 143 via a touch screen of user input unit 16 of display unit 14 if it is determined that a user gesture to the shared image is present. Gesture image 144 in accordance with the present embodiment is an example of edited information in accordance with the present invention.
    [00053] Referring to Figure 13, if the shared image 143 is edited in step 303, the controller 18 of the mobile terminal 1 transmits to the duplicated mobile terminal 2 the video call data added with the shared image 143 and the edited information 144 through wireless communication unit 13. According to another modality, editing of the shared image can be omitted and the video call data may not include the edited information 144. According to the following modality, the shared image is edited as an example, but the present invention is not limited thereto.
    [00054] The method of transmitting to the mobile terminal duplicated the video call data added with the shared image 143 and the edited information 144 may vary. For example, the controller 18 of the mobile terminal 1 can combine the video 241 of the video call and the shared image 143 to generate combined images 241 and 143, and can transmit to the duplicated mobile terminal 2 the video 241 of the video call and the shared image 143 as combined images 241 and 143. Additionally, controller 18 can reflect the edited information for the combined image.
    [00055] According to another embodiment, the controller 18 of the mobile terminal 1 can transmit to the duplicated mobile terminal 2 the shared image 143 and the edited information 144 individually. For example, the controller 18 can split individual video call data blocks or provide blocks of a plurality of video call data, and load the video data 241 of the video call, the shared image 143 and the cited information to the block provided and transmit such data to the duplicated mobile terminal 2.

    [00056] Referring to Figure 4, in step 402, the controller 28 of the mobile terminal 2 receives the video call data including the shared image 143 and the edited information 144 from the duplicated mobile terminal 1 during a video call. For example, the controller 28 of the mobile terminal 2 can determine whether the duplicated mobile terminal 1 transmits the video 241 of the video call, the shared image 143 and the edited information 144 as a combined image, and controls the wireless communication unit 23 to receive the combined image. The controller 28 of the mobile terminal 2 can confirm the identification information included in the video call data received from the duplicated mobile terminal 1, and control the wireless communication unit 23 to separately receive the video 241 of the video call, the shared image 143 and edited information 144 based on the identifying information.
    [00057] As shown in Figure 8, the display unit 24 of the mobile terminal 2, controlled by the controller 28, displays the shared image 243 reflecting the edited information 244, together with the video 241 of the video call, during the call. video at step 403. For example, the controller 28 of the mobile terminal 2 can receive combined images 241, 243 and 244 from the duplicated mobile terminal 1, and display such combined images 241, 243 and 244 on the display unit 24. The controller 28 of the mobile terminal 2 can process the video call video data 241, the shared image 243 and the edited information 244 received as individual information, and display on the display unit 24 the video call video 241 and the shared image 243 reflecting edited information 244.
    [00058] As above, the shared image 243 and the edited information 244 according to the present embodiment are displayed together with the video 241 of the video call. Consequently, a user of the mobile terminal 2 can immediately receive and view the edited result of the shared image from the correlative terminal during a video call to the correlative terminal, and can share more information efficiently.
    [00059] According to another embodiment, referring to step 404 in Figure 4, the controller 28 of the mobile terminal 2 can edit the shared image 243 according to user input through the user input unit 26, and in step 405 transmits to the duplicated mobile terminal 1 the edited information 245 of Fig. 9 in accordance with user input. With reference to step 305 in Figure 3, the controller 18 of the mobile terminal 1 receives the edited information 245 of the duplicated mobile terminal 2, and displays on the display unit 14 the shared image 143 reflecting the edited information of the correlative terminal 145, as shown in Figure 7. Consequently, the two parties to the call can participate in editing the shared image, and share the image more conveniently.
    [00060] Editing of shared image 143 is not limited to the preceding mode, and may vary. For example, enlarging, reducing or rotating the shared image 143 or changing the color or adjustment of at least a part of the shared image 143 may be included under editing. Text input by a user can also be added to shared image 143.
