Abstract

A mobile terminal including a display; and a controller configured to display a first image including a focusing region and an out-focusing region on the display, wherein a depth of the first image corresponds to a first depth, and display a second image with the out-focusing region adjusted into a second depth in response to a first input signal.

First claim

What is claimed is:

1. A mobile terminal, comprising:
at least first and second cameras,
a display; and
a controller configured to:
display a first image including a focusing region and an out-focusing region on the display, wherein a depth of the first image corresponds to a first depth,
extract an image among at least one image related to the first image, wherein a depth of the extracted image corresponds to a second depth,
create a second image by synthesizing a selected specific region of the extracted image with the first image, wherein the selected region is in the out-focusing region,
display the second image in response to a first input signal,
capture the first image obtained through the first camera and a third image obtained through the second camera in response to a second input signal,
create a fourth image based on a static object included in the first image and a dynamic object included in the third image, and
display the fourth image based on the first image and the third image,
wherein the first image comprises an image captured during an exposure time over a preset time and the third image comprises an image captured during an exposure time within the preset time.

2. The mobile terminal of claim 1 , wherein the first input signal corresponds to the selection of the specific region in the out-focusing region.

3. The mobile terminal of claim 2 , wherein the controller is further configured to determine the second depth based on at least one of a pressure of the first input signal and a count of the first input signal.

4. The mobile terminal of claim 2 , wherein the controller is further configured to display a pop-up message on the display indicating the selected region, in response to a second input signal for the selected region.

5. The mobile terminal of claim 1 , wherein the controller is further configured to:
crop common regions of the first image and the third image, and
display the fourth image based on the cropped first image and the cropped third image.

6. The mobile terminal of claim 1 , wherein the fourth image comprises an image HDR (high dynamic range) synthesized based on the first image and the third image.

7. The mobile terminal of claim 1 , wherein the controller is further configured to capture a plurality of images corresponding to a view angle area of the first camera consecutively in response to a second input signal.

8. The mobile terminal of claim 7 , wherein the controller is further configured to:
display a preview image corresponding to the first image and an aperture control bar on the display, and
change the first depth of the preview image into a third depth in response to an input signal of the aperture control bar.

9. The mobile terminal of claim 8 , wherein if the third depth corresponds to a depth range failing to be supported by the first camera, the controller is further configured to display the preview image by changing the preview image into a blurred image.

10. The mobile terminal of claim 9 , wherein the controller is further configured to create and save an output image corresponding to the third depth based on the plurality of the images.

11. The mobile terminal of claim 1 , wherein if the first image corresponds to a plurality of preview images, the controller is further configured to capture either a first preview image through the first camera or a second preview image through the second camera in response to a second input signal.

12. The mobile terminal of claim 11 , wherein the controller is further configured to output locations of the plurality of the preview images on the display based on a direction of motion of an object sensed by at least one of the first camera and the second camera.

13. A method for focusing, comprising:
A method of controlling a mobile terminal, the method comprising:
displaying, via a display of the mobile terminal, a first image including a focusing region and an out-focusing region, wherein a depth of the first image corresponds to a first depth;
extracting an image among at least one image related to the first image, wherein a depth of the extracted image corresponds to a second depth;
creating a second image by synthesizing a selected specific region of the extracted image with the first image, wherein the selected region is in the out-focusing region; and
displaying, via the display, the second image in response to a first input signal; capturing the first image obtained through a first camera and a third image obtained through a second camera in response to a second input signal;
creating a fourth image based on a static object included in the first image and a dynamic object included in the third image; and
displaying the fourth image based on the first image and the third image, wherein the first image comprises an image captured during an exposure time over a preset time and the third image comprises an image captured during an exposure time within the preset time.

14. The method of claim 13 , wherein the first input signal corresponds to the selection of the specific region in the out-focusing region.
