Mobile terminal having dual cameras to created composite image and method thereof

1. A mobile terminal comprising:

a first camera on a first surface of the mobile terminal;

a second camera on a second surface of the mobile terminal;

a display unit;

a controller configured to:

control the first camera to obtain a first image,

control the second camera to obtain a second image,

extract a first object from the first image, the first object including a first sub-object and a second sub-object,

extract a second object from the second image, and

display the extracted second object on the first image by overlaying the first sub-object on a portion of the second object and overlaying the second object on a portion of the second sub-object;

a distance sensing module configured to obtain distance information between the first object and the mobile terminal;

save the distance information to be matched to the first object;

receive a distance setting command for setting a distance between the second object and the mobile terminal;

determine an order relationship between the second object and the first object contacting with the second object based on the set distance between the second object and the mobile terminal in response to the distance setting command; and

determine a range of the second object, which will overlay the first image, in accordance with the determined order relationship.

2. The mobile terminal of claim 1 , wherein the first surface is a rear surface of the mobile terminal and the second surface is a front surface of the mobile terminal, and

wherein the display unit is on the second surface of the mobile terminal.

3. The mobile terminal of claim 1 , wherein the controller is further configured to:

adjust a size of the second object depending on a size of the first object.

4. The mobile terminal of claim 1 , wherein the controller is further configured to:

detect location information of the extracted first object, and

display at least one indicator on the display unit indicating a region at which the second object will be located in the first image, based on a result of the detection.

5. The mobile terminal of claim 1 ,

wherein the first object includes a plurality of sub-objects including the first sub-object and the second sub-object.

6. The mobile terminal of claim 5 , wherein the controller is further configured to:

detect at least one of a size of each of the plurality of sub-objects, a space between two of the plurality of sub-objects adjacent to each other and location information of each of the plurality of sub-objects, and

display at least one indicator on the display unit indicating a display region, at which the second object will be located in the first image, based on a result of the detection.

7. The mobile terminal of claim 6 , wherein the controller is further configured to:

receive a selection of the at least one indicator, and

control the display unit to display the second object on the display region indicated by the selected indicator so the second object overlays the first image.

8. The mobile terminal of claim 1 , wherein the first object includes a plurality of sub-objects including the first sub-object and the second sub-object, and

wherein the controller is further configured to save and match the distance information to be matched to each of the plurality of sub-objects.

9. A method for controlling a mobile terminal, the method comprising:

obtaining a first image via a first camera of the mobile terminal;

obtaining a second image via a second camera of the mobile terminal;

extracting, via a controller of the mobile terminal, a first object from the first image, the first object including a first sub-object and a second sub-object;

extracting, via the controller, a second object from the second image;

displaying the extracted second object on the first image on a display unit of the mobile terminal by overlaying the first sub-object on a portion of the second object and overlaying the second object on a portion of the second sub-object;

obtaining distance information between the first object and the mobile terminal via a distance sensing module of the mobile terminal;

saving the distance information to be matched to the first object;

receiving a distance setting command for setting a distance between the second object and the mobile terminal;

determining an order relationship between the second object and the first object contacting with the second object based on the set distance between the second object and the mobile terminal in response to the distance setting command; and

determining a range of the second object, which will overlay the first image, in accordance with the determined order relationship.
