Abstract

A mobile terminal is provided that includes a first camera to obtain a first image of an object, and a second camera to obtain a second image of an object, the second camera being separated from the first camera by a distance d. The mobile terminal also includes a controller to determine the distance d between the first camera and the second camera when the first camera obtains the first image of the object at a same time that the second camera obtains the second image. Still further, the mobile terminal includes a varying device to allow the distance d between the first camera and the second camera to vary, and a display to display a combination of the first image and the second image to allow a perceived three-dimensional (3D) image of the object.

Claims

1. A mobile terminal comprising:

a first camera to obtain a first image of an object;

a second camera to obtain a second image of an object, the second camera being separated from the first camera by a distance d;

a controller to determine the distance d between the first camera and the second camera when the first camera obtains the first image of the object at a same time that the second camera obtains the second image;

a varying device to allow the distance d between the first camera and the second camera to vary; and

a display to display a combination of the first image and the second image to allow a perceived three-dimensional (3D) image of the object.

2. The mobile terminal of claim 1, wherein in a first mode of the mobile terminal, the distance d between the first camera and the second camera is greater than the distance d between the first camera and the second camera in a second mode of the mobile terminal.

3. The mobile terminal of claim 2, wherein in the first mode, the distance d between the first camera and the second camera is greater than 1.5 inches and is less than 2.5 inches when the 3D image is to be displayed on the display of the mobile terminal.

4. The mobile terminal of claim 2, wherein in the second mode, the distance d between the first camera and the second camera is less than 1.5 inches when the 3D image is to be displayed on the display of the mobile terminal or on a display of a television.

5. The mobile terminal of claim 2, wherein the distance d between the first camera and the second camera is greater than 1.5 inches and is less than 2.5 inches when the 3D image is to be displayed on the display of the mobile terminal, and wherein the distance d between the first camera and the second camera is less than 1.5 inches when the 3D image is to be displayed on the display of the mobile terminal or on a display of a television.

6. The mobile terminal of claim 1, wherein the display displays information of a 3D level of an object displayed within the combination of the first image and the second image.

7. The mobile terminal of claim 6, wherein the information of the 3D level is displayed in real-time while the first image and the second image are being obtained.

8. The mobile terminal of claim 6, wherein the information of the 3D level is displayed in real-time when the first image and the second image are obtained.

9. The mobile terminal of claim 1, wherein information of the distance is stored in a storage device of the mobile terminal.

10. The mobile terminal of claim 1, wherein the varying device moves the second camera relative to the first camera.

11. A mobile terminal comprising:

a storage device to store a first image of an object from a first camera and to store a second image of the object from a second camera;

a controller to determine a distance d between the first camera and the second camera when the first camera and the second camera obtain the first image and the second image of the object at a same time; and

a display to display a combination of the first image and the second image to allow a perceived three-dimensional (3D) image of the object.

12. The mobile terminal of claim 11, wherein in a first mode of the mobile terminal, the distance d between the first camera and the second camera is greater than the distance d between the first camera and the second camera in a second mode of the mobile terminal.

13. The mobile terminal of claim 12, wherein in the first mode, the distance d between the first camera and the second camera is greater than 1.5 inches and is less than 2.5 inches when the 3D image is to be displayed on the display of the mobile terminal.

14. The mobile terminal of claim 12, wherein in the second mode, the distance d between the first camera and the second camera is less than 1.5 inches when the 3D image is to be displayed on the display of the mobile terminal or on a display of a television.

15. The mobile terminal of claim 12, wherein the distance d between the first camera and the second camera is greater than 1.5 inches and is less than 2.5 inches when the 3D image is to be displayed on the display of the mobile terminal, and wherein the distance d between the first camera and the second camera is less than 1.5 inches when the 3D image is to be displayed on the display of the mobile terminal or on a display of a television.

16. The mobile terminal of claim 11, wherein the display displays information of a 3D level of an object displayed within the combination of the first image and the second image.

17. The mobile terminal of claim 16, wherein the information of the 3D level is displayed in real-time while the first image and the second image are being obtained.

18. The mobile terminal of claim 16, wherein the information of the 3D level is displayed in real-time when the first image and the second image are obtained.

19. The mobile terminal of claim 11, further comprising a varying device to vary the distance d between the first camera and the second camera.

20. The mobile terminal of claim 19, wherein the varying device moves the second camera relative to the first camera.
