Abstract

A portable device and a method for controlling brightness thereof are provided. The portable device includes a display, a sensor and a controller. The display provides a display region that is displayed with a first brightness. The sensor senses a surrounding brightness of the portable device. The controller controls the display to display a partial region corresponding to a User Interaction (UI) element in the display region with a second brightness based on the sensed surrounding brightness.

First claim

What is claimed is:

1 . A portable device comprising:
a display configured to provide a display region that is displayed with a first brightness; a sensor configured to sense a surrounding brightness of the portable device; and a controller configured to control the display to display a partial region corresponding to a User Interaction (UI) element in the display region with a second brightness based on the sensed surrounding brightness.

2 . The portable device as claimed in claim 1 , wherein the controller controls the display to display a region excluding the partial region of the display region continuously with the first brightness, or with a third brightness that is lower than the second brightness.

3 . The portable device as claimed in claim 1 , wherein the controller controls the display to display the partial region with the second brightness if an illuminance value corresponding to the sensed surrounding brightness is equal to or greater than a threshold value, or a changed value of the illuminance value is equal to or greater than a threshold value.

4 . The portable device as claimed in claim 1 , wherein the partial region corresponding to the UI element corresponds to a layout region including the UI element, a field region including the UI element, or a plurality of pixels displaying the UI element.

5 . The portable device as claimed in claim 1 , wherein the UI element comprises a UI element for controlling the brightness of the display region.

6 . The portable device as claimed in claim 5 , wherein the sensor senses a user input for controlling the brightness of the display region through the UI element, and
the controller controls the display to display the display region with a fourth brightness in response to the user input.

7 . The portable device as claimed in claim 1 , wherein in the case where content is displayed in the display region, the UI element comprises a UI element for controlling the content.

8 . The portable device as claimed in claim 1 , wherein in the case where a lock screen is displayed in the display region, the UI element comprises at least one UI element for releasing the lock screen.

9 . The portable device as claimed in claim 1 , wherein the controller identifies the partial region corresponding to the UI element in the display region.

10 . The portable device as claimed in claim 1 , wherein the first brightness corresponds to a first luminance value, and the second brightness corresponds to a second luminance value different from the first luminance value.

11 . A method for controlling brightness of a portable device, comprising:
displaying a display region with a first brightness; sensing a surrounding brightness of the portable device; and displaying a partial region corresponding to a User Interaction (UI) element in the display region with a second brightness based on the sensed surrounding brightness.

12 . The method as claimed in claim 11 , wherein the displaying the partial region with the second brightness comprises displaying a region excluding the partial region of the display region continuously with the first brightness, or with third brightness that is lower than the second brightness.

13 . The method as claimed in claim 11 , wherein the displaying the partial region with the second brightness comprises displaying the partial region with the second brightness if an illuminance value corresponding to the sensed surrounding brightness is equal to or greater than a threshold value, or a changed value of the illuminance value is equal to or greater than a threshold value.

14 . The method as claimed in claim 11 , wherein the partial region corresponding to the UI element corresponds to a layout region including the UI element, a field region including the UI element, or a plurality of pixels displaying the UI element.

15 . The method as claimed in claim 11 , wherein the UI element comprises a UI element for controlling the brightness of the display region.

16 . The method as claimed in claim 15 , further comprising:
sensing a user input for controlling the brightness of the display region through the UI element; and displaying the display region with a fourth brightness in response to the user input.

17 . The method as claimed in claim 11 , wherein in the case where content is displayed in the display region, the UI element comprises a UI element for controlling the content.

18 . The method as claimed in claim 11 , wherein in the case where a lock screen is displayed in the display region, the UI element comprises at least one UI element for releasing the lock screen.

19 . The method as claimed in claim 11 , wherein the displaying the partial region with the second brightness comprises identifying the partial region corresponding to the UI element in the display region, and displaying the partial region corresponding to the UI element with the second brightness.

20 . A non-transitory recording medium recorded with a program for controlling brightness of a portable device that performs:
displaying a display region of the portable device with a first brightness; and displaying a partial region corresponding to a User Interaction (UI) element in the display region with a second brightness based on surrounding brightness of the portable device.
