Abstract

A mobile communication terminal is provided. The mobile communication terminal includes a communication module for transmitting and receiving data in order to perform audiovisual communication with at least one other party'"'"'s terminal; a camera module for photographing an image; a touch screen for displaying a first image received from the at least one other party'"'"'s terminal and a second image acquired from the camera module; and a controller for changing, when the first image or the second image displayed on the touch screen is touched, a display manner of the first image and the second image.

Claims

1. A mobile communication terminal, comprising:

a communication module configured to transmit and receive data to perform a video call with at least one other party'"'"'s terminal;

a camera module;

a touch screen operatively connected to the camera module and configured to display images including a first image received from the at least one other party'"'"'s terminal and a second image acquired from the camera module; and

a controller operatively connected to the touch screen and configured to

control the touch screen to change a display manner of the first image and/or the second image in response to a touch input to one of the first and second images displayed on the touch screen, and

control the touch screen to change a display direction of the touched image if the touched image is larger than the untouched reduced image,

wherein the display manner comprises at least one of a display position, size, and direction.

2. The mobile communication terminal of claim 1, wherein the changed display direction is a direction rotated by 90°

clockwise or counterclockwise.

3. The mobile communication terminal of claim 1, wherein the controller is configured to control the touch screen to enlarge the touched image such that at least one of a horizontal edge and a vertical edge of the touched image agrees with a length or a width of the touch screen according to the direction change.

4. The mobile communication terminal of claim 3, wherein the controller is configured to control the touch screen to reduce the size of the untouched reduced image not to overlap the enlarged touched image.

5. The mobile communication terminal of claim 3, wherein the controller is configured to control the touch screen to display the untouched reduced image as a Picture In Picture (PIP) within the enlarged touched image.

6. The mobile communication terminal of claim 3, wherein the controller is configured to control the touch screen

to display a menu key including at least one icon to execute specific functions on the touch screen such that the menu key is not overlapped with the enlarged touched image, and

to display the at least one icon such that the at least one icon is overlapped with a part of the enlarged touched image if the menu key is touched.

7. The mobile communication terminal of claim 3, wherein the controller is configured to control the touch screen to return the touched image and the untouched reduced image to a previous display state if the enlarged touched image is further touched.

8. The mobile communication terminal of claim 7, wherein the controller is configured to control the touch screen to display on the touch screen a third image stored in the mobile communication terminal, and to replace the untouched reduced image with the third image if the third image is touched.

9. The mobile communication terminal of claim 8, wherein the controller is configured to control the touch screen to change at least one of a display position, size, and direction of the enlarged touched image with a corresponding one of a display position, size, and direction of the third image if the replaced third image is touched.

10. The mobile communication terminal of claim 8, wherein the controller is configured to control the touch screen to display the untouched reduced image in a position in which the replaced third image was previously displayed if the replaced third image is touched.

11. The mobile communication terminal of claim 10, wherein the controller is configured to control the touch screen to return the untouched reduced image and third image to a previous display state if the untouched reduced image displayed in the previous display position of the third image is touched.

12. The mobile communication terminal of claim 3, wherein the controller is configured to control the touch screen to display a menu key for turning back the enlarged touched image and the untouched reduced image into a previous display state upon touching of the menu key, wherein the menu key is displayed not to be overlapped with the enlarged touched image.

13. The mobile communication terminal of claim 1, wherein the controller is configured to control the touch screen to display on the touch screen a display orientation icon configured to enable a user to rotate the display.

14. A method of controlling a display for a video call with at least one other party'"'"'s terminal in a mobile communication terminal comprising a touch screen and a camera module, the method comprising:

displaying images on the touch screen, including

displaying a first image received from the at least one other party'"'"'s terminal, and

displaying a second image acquired from the camera module; and

controlling the touch screen to change a display manner of the first image and the second image in response to a touch input to one of the first and second images,

wherein the display manner is at least one of a display position, size and direction of the first and second image, and

wherein the step of controlling the touch screen comprises;

changing a display direction of the touched image if the touched image is larger than the untouched reduced image.

15. The method of claim 14, wherein the step of changing a display direction comprises:

rotating the display direction 90°

clockwise or counterclockwise.

16. The method of claim 14, wherein the step of controlling the touch screen comprises:

enlarging the touched image such that at least one of a horizontal edge and a vertical edge agrees with a length or a width of the touch screen.

17. The method of claim 16, wherein the step of enlarging comprises:

preventing the untouched reduced image from overlapping the enlarged touched image.

18. The method of claim 16, wherein the untouched reduced image is displayed as a PIP within the enlarged touched image.

19. The method of claim 16, further comprising:

displaying a menu key for displaying at least one icon to execute specific functions on the touch screen without overlapping the menu key with the enlarged touched image; and

displaying the at least one icon overlapped with a part of the enlarged and displayed image if the menu key is touched.

20. The method of claim 16, further comprising:

returning the enlarged touched image and the untouched reduced image to a previous display state if the enlarged touched image is further touched.

21. The method of claim 20, further comprising:

displaying a third image stored in the mobile communication terminal; and

replacing the untouched reduced image with the third image if the third image is touched.

22. The method of claim 21, further comprising:

changing at least one of a display position, size, and direction of the first image to a corresponding one of a display position, size, and direction of the third image if the replaced third image is touched.

23. The method of claim 21, wherein the step of replacing comprises:

displaying the untouched reduced image in a position in which the third image was previously displayed.

24. The method of claim 23, further comprising:

returning the exchanged untouched reduced image and third image to a previous display state when the untouched reduced image displayed in the previous position of the third image is touched.

25. The method of claim 16, further comprising:

displaying a menu key for turning back the enlarged touched image and the untouched reduced image to a previous display state, wherein the menu key is not overlapped with the enlarged touched image.

26. The method of claim 14, further comprising:

displaying on the touch screen a display orientation icon configured to enable a user to rotate the display.
