Abstract

A mobile terminal and controlling method thereof are disclosed, by which a sharp and clear photo can be composed using a plurality of photos taken by burst shooting. The present invention includes a camera, a sensing unit configured to detect a surrounding brightness, a user input unit configured to receive a photographing command, and a controller, if the photographing command is received, taking a first number of photos by burst shooting, the controller outputting a shaking eliminated photo based on a second number of photo(s) selected from the first number of the taken photos, wherein the second number is determined based on the detected surrounding brightness.

First claim

What is claimed is:

1 . A mobile terminal comprising:
a camera; a sensing unit configured to detect a surrounding brightness; a user input unit configured to receive a photographing command; and a controller configured to:
when the photographing command is received, take a first number of photos by burst shooting, and
output a shaking eliminated photo based on a second number of photo(s) selected from the first number of the taken photos,
wherein the second number is determined based on the detected surrounding brightness.

2 . The mobile terminal of claim 1 ,
wherein in obtaining the shaking eliminated photo based on the second number of the photos, the controller further configured to:
apply a shaking elimination algorithm divided into a plurality of application levels, and
determine each of the application levels based on the detected surrounding brightness.

3 . The mobile terminal of claim 1 , wherein the controller further configured to select the determined second number of the photo(s) from the first number of the taken photos based on sharpness.

4 . The mobile terminal of claim 3 , wherein the controller further configured to:
calculates a sharpness value of each of the first number of the taken photos, and select the determined second number of the photo(s) in higher order of the calculated sharpness value.

5 . The mobile terminal of claim 1 , wherein each pixel of the shaking eliminated photo is configured with an average value of corresponding pixel(s) of the second number of the selected photo(s).

6 . The mobile terminal of claim 1 , wherein the shaking eliminated photo comprises a photo composed based on the second number of the photo(s).

7 . The mobile terminal of claim 6 , further comprising a sensing unit configured to detect a motion of the mobile terminal on performing the burst shooting, and
wherein the shaking eliminated photo comprises a photo composed by adjusting a location offset of each of the second number of the photo(s) based on the detected motion.

8 . The mobile terminal of claim 1 , further comprising a touchscreen, wherein the controller further configured to output a thumbnail preview corresponding to the second number of the taken photo(s) through the touchscreen.

9 . The mobile terminal of claim 8 ,
wherein each thumbnail of the thumbnail preview includes a check box, and wherein the controller further configured to output the shaking eliminated photo based on the photo selected through the check box from the second number of the photo(s).

10 . The mobile terminal of claim 1 , further comprising a touchscreen configured to output a preview screen for one of the first number of the taken photo(s),
wherein when an input of designating a partial region on the preview screen is received from a user, the controller further configured to output the shaking eliminated photo based on the designated partial region(s) for each of the first number of the taken photo(s).

11 . A method of controlling a mobile terminal, comprising the steps of:
detecting a surrounding brightness; receiving a photographing command through a user input unit; when the photographing command is received, taking a first number of photos by burst shooting through a camera; and outputting a shaking eliminated photo based on a second number of photo(s) selected from the first number of the taken photos, wherein the second number is determined based on the detected surrounding brightness.

12 . The method of claim 11 , further comprising the step of in obtaining the shaking eliminated photo based on the second number of the photos, applying a shaking elimination algorithm divided into a plurality of application levels, wherein each of the application levels is determined based on the detected surrounding brightness.

13 . The method of claim 11 , the outputting step, comprising the step of selecting the determined second number of the photo(s) from the first number of the taken photos based on sharpness.

14 . The method of claim 13 , further comprising the step of calculating a sharpness value of each of the first number of the taken photos, wherein the outputting step comprises the step of selecting the determined second number of the photo(s) in higher order of the calculated sharpness value.

15 . The method of claim 11 , wherein each pixel of the shaking eliminated photo is configured with an average value of corresponding pixel(s) of the second number of the selected photo(s).

16 . The method of claim 11 , wherein the shaking eliminated photo comprises a photo composed based on the second number of the photo(s).

17 . The method of claim 16 , further comprising the step of detecting a motion of the mobile terminal on performing the burst shooting, wherein the shaking eliminated photo comprises a photo composed by adjusting a location offset of each of the second number of the photo(s) based on the detected motion.

18 . The method of claim 11 , further comprising the step of outputting a thumbnail preview corresponding to the second number of the taken photo(s) through a touchscreen.

19 . The method of claim 18 , wherein each thumbnail of the thumbnail preview includes a check box and wherein the outputting step comprises the step of outputting the shaking eliminated photo based on the photo selected through the check box from the second number of the photo(s).

20 . The method of claim 11 , the outputting step, comprising the steps of:
Further outputting a preview screen for one of the first number of the taken photo(s); and when an input of designating a partial region on the preview screen is received from a user, outputting the shaking eliminated photo based on the designated partial region(s) for each of the first number of the taken photo(s).
