Abstract

A mobile terminal including a main body; a display unit arranged on a front side of the main body, and configured to display a video communication screen in a first direction when a video communication event occurs; a camera arranged in a lower end portion of the front side and configured to capture an image during the video communication event; a sensing unit installed in the main body, and configured to detect a motion of the main body in response to the video communication event; and a controller configured to switch a displaying direction of the video communication screen from the first direction to a second direction based on the detected motion of the main body.

Claims

1. A mobile terminal comprising:

a main body;

a display unit arranged on a front side of the main body, and configured to display a video communication screen in a first direction when a video communication event occurs;

a camera arranged in a lower end portion of the front side and configured to capture an image during the video communication event;

a sensing unit installed in the main body, and configured to detect a motion of the main body in response to the video communication event; and

a controller configured to switch a displaying direction of the video communication screen from the first direction to a second direction based on the detected motion of the main body.

2. The mobile terminal according to claim 1, wherein the motion of the main body is defined as a rotation of the main body with respect to a predetermined imaginary reference axis, and

wherein the controller is further configured to calculate an angle between the main body and the reference axis when the sensing unit detects the motion of the main body.

3. The mobile terminal according to claim 2, wherein when the calculated angle is 90 degrees or 180 degrees, the controller is further configured to switch the displaying direction of the screen from the first direction to the second direction such that the captured image is rotated by 90 degrees or by 180 degrees with respect to the reference axis to correspond to the calculated angle.

4. The mobile terminal according to claim 1, wherein the controller is further configured to output alert information indicating the main body should be rotated in response to the video communication event.

5. The mobile terminal according to claim 4, wherein the alert information is output as at least one of a sound, a vibration, and a pop-up window.

6. The mobile terminal according to claim 4, wherein the controller is further configured to control the sensing unit to detect the motion of the main body after the alert information is output.

7. The mobile terminal according to claim 1, wherein the controller is further configured to switch the video communication screen back to the first direction, when the video communication event is terminated.

8. The mobile terminal according to claim 2, wherein the controller is further configured to switch the displaying direction of the video communication screen from the first direction to the second direction when the detected motion of the main body meets a reference condition, and

wherein the motion of the main body meets the reference condition when the motion of the main body is from a first position corresponding to the predetermined imaginary reference axis to a second position inclined at a predetermined angle with respect to the first position.

9. The mobile terminal according to claim 8, wherein the controller is further configured to transmit a substitute image instead of the captured image to a counterpart terminal in the video communication event, when the main body is moved from the second position to the first position.

10. The mobile terminal according to claim 9, wherein the controller is further configured display a plurality of substitute images on the display unit when the main body is moved from the second position to the first position, and transmit a user-selected substitute image to the counterpart terminal.

11. The mobile terminal according to claim 9, wherein the controller is further configured to display the captured image instead of the substitute image when the main body is switched from the first position back to the second position.

12. The mobile terminal according to claim 8, wherein the controller is further configured to switch video communication in the video communication event to audio communication when the main body is moved from the second position to the first position.

13. The mobile terminal according to claim 1, wherein the video communication event is one of a video communication receiving event and a video communication transmitting event, and

wherein the controller is further configured to start a video communication mode based on an input communication connection control command when the motion of the main body is moved to meet a reference condition based on an occurrence of the video communication receiving event, and start an audio communication mode based on the communication connection control command when the motion of the main body does not meet the reference condition.

14. The mobile terminal according to claim 1, wherein the controller is further configured to display a pop-up window for selecting an audio communication mode or a video communication mode on the display unit in response to the occurrence of the video communication receiving event, and control the sensing unit to detect the motion of the main body based on the selection of the video communication mode by a user.

15. A mobile terminal comprising:

a main body having a front side, a back side, and lateral sides;

a display unit arranged on the front side of the main body and configured to display visual information;

a camera arranged in a lower end portion of the front side;

a speaker arranged in the main body and configured to output sound associated with a telephone call; and

a speaker hole arranged in an upper end portion of the main body and corresponding to the speaker to output the sound from the speaker.

16. The mobile terminal according to 15, wherein the visual information displayed on the display unit is at least one of an image corresponding to an image signal input through the camera and an image input during video communication.

17. The mobile terminal according to 15, wherein the speaker hole is arranged in the upper end portion of the front side or in a region of the lateral side of the main body, which is adjacent to the upper end portion.

18. The mobile terminal according to 15, wherein the speaker is arranged on the back side or on the lateral side of the display unit.

19. The mobile terminal according to claim 18, further comprising:

a guide unit configured to guide the sound from the speaker arranged on the back side through the speaker hole.

20. The mobile terminal according to 15, further comprising:

a user input unit arranged in the lower end portion of the front side.

21. The mobile terminal according to 15, further comprising:

a bezel unit enclosing the display unit arranged on the front side,

wherein a lower bezel of the bezel unit positioned in a region corresponding to the camera is wider than at least one of left and right bezels and an upper bezel of the bezel unit with the display unit in between.

22. The mobile terminal according to 15, further comprising:

a window arranged on the front side,

wherein the speaker hole is arranged in an upper end portion of the widow, and one region of a lower end portion of the window is transparent for the camera arranged in the lower end portion of the front side to receive a video signal.
