Abstract

A mobile terminal and controlling method therein are disclosed, by which photos/videos can be conveniently taken/made using a plurality of different preview images taken with at least two cameras. The present invention includes a 1 st camera, a 2 nd camera, a touchscreen, and a controller controlling a 1 st preview image taken with the 1 st camera and a 2 nd preview image taken with the 2 nd camera in camera photograph mode to be simultaneously displayed on the touchscreen at least, the controller controlling an image/video corresponding to a prescribed one of the simultaneously displayed preview images to be taken/made.

First claim

What is claimed is:

1. A mobile terminal comprising:
a first camera configured to obtain an image;
a second camera configured to obtain an image;
a touchscreen configured to display information; and
a controller configured to:
cause the touchscreen to display a first preview image generated via the first camera, a second preview image generated via the second camera, and a third preview image including the first preview image and the second preview image that overlap each other at least partially, wherein the first preview image, the second preview image, and the third preview image that are displayed concurrently do not overlap each other;
record a first video corresponding to the first preview image in response to a first touch input received and maintained at the first preview image;
record a second video corresponding to the third preview image in response to a second touch input received and maintained at the second preview image, the second touch input received while the first touch input is maintained at the first preview image;
record a third video corresponding to the second preview image when the first touch input is released from the first touch input and the second touch input is maintained at the second preview image; and
stop the recording of the third video when the second touch input is released from the second preview image to create a single video file comprising the first video, the second video, and the third video.

2. The mobile terminal of claim 1 , wherein:
the controller is further configured to enter a multi-preview mode in response to an input for executing a camera application to cause the displaying of the first preview image, the second preview image, and the third preview image;
the controller is further configured to enter the multi-preview mode in response to an input for activating the multi-preview mode received while a photograph mode is activated; or
the controller is further configured to enter the multi-preview mode in response to an input for executing an independent application that is not same as the camera application.

3. The mobile terminal of claim 1 , wherein the controller is further configured to apply setup values of both the first and second preview images to the first preview image in response to dragging of the first preview image to the second preview image.

4. The mobile terminal of claim 1 , wherein the controller is further configured to cause the touchscreen to:
display the first, second, or third preview image in a full screen size in response to a third touch input applied to the first, second, or third preview image; and
redisplay the first, second, and third preview images concurrently in response to a fourth touch input applied to the first, second, or third preview image displayed in the full screen size.

5. The mobile terminal of claim 1 , wherein the controller is further configured to cause the touchscreen to display a photograph button in a second region of the touchscreen in response to dragging of at least the first, second, or third preview image displayed in a first region of the touchscreen to the second region.

6. The mobile terminal of claim 5 , wherein the controller is further configured to:
record an image corresponding to the second region in response to a third touch input applied to the photograph button while the second region includes the dragged at least first, second, or third preview image; and
record a video corresponding to the second region in response to a fourth touch input applied to the photograph button while the second region includes the dragged at least first, second, or third preview image.

7. The mobile terminal of claim 1 , wherein the controller is further configured to cause the touchscreen to display the first, second, or third preview image in response to dragging of the first, second, or third preview image to an edge of the touchscreen such that only the dragged first, second, or third preview image is displayed.

8. A method of controlling a mobile terminal, the method comprising:
displaying, on a touchscreen, a first preview image generated via a first camera, a second preview image generated via a second camera, and a third preview image including the first preview image and the second preview image that overlap each other at least partially, wherein the first preview image, the second preview image, and the third preview image that are displayed concurrently do not overlap each other;
recording a first video corresponding to the first preview image in response to a first touch input received and maintained at the first preview image;
recording a second video corresponding to the third preview image in response to a second touch input received and maintained at the second preview image, the second touch input received while the first touch input is maintained at the first preview image;
recording a third video corresponding to the second preview image when the first touch input is released from the first preview image and the second touch input is maintained at the second preview image; and
stopping the recording of the third video when the second touch input is released from the second preview image to create a single video file comprising the first video, the second video, and the third video.

9. The method of claim 8 , further comprising:
entering a multi-preview mode in response to an input for executing a camera application to cause the displaying of the first preview image, the second preview image, and the third preview image;
entering the multi-preview mode in response to an input for activating the multi-preview mode received while a photograph mode is activated; or
entering the multi-preview mode in response to an input for executing an independent application that is not same as the camera application.

10. The method of claim 8 , further comprising:
applying setup values of both the first and second preview images to the first preview image in response to dragging of the first preview image to the second preview image.

11. The method of claim 8 , further comprising:
displaying the first, second, or third preview image in a full screen size in response to a third touch input applied to the first, second, or third preview image; and
redisplaying the first, second, and third preview images concurrently in response to a fourth touch input applied to the first, second, or third preview image displayed in the full screen size.

12. The method of claim 8 , further comprising:
displaying a photograph button in a second region of the touchscreen in response to dragging of at least the first, second, or third preview image displayed in a first region of the touchscreen to the second region.

13. The method of claim 12 , further comprising:
recording an image corresponding to the second region in response to a third touch input applied to the photograph button while the second region includes the dragged at least first, second, or third preview image; and
recording a video corresponding to the second region in response to a fourth touch input applied to the photograph button while the second region includes the dragged at least first, second, or third preview image.

14. The method of claim 8 , further comprising:
displaying the first or second preview image in response to dragging of the first, second, or third preview image to an edge of the touchscreen such that only the dragged first, second, or third preview image is displayed.
