Abstract

A display apparatus is provided. The display apparatus includes a sensor configured to sense ambient light, a display configured to provide a screen including a first area which displays content and a second area outside the first area and a processor configured to change a size of the second area based on the sensed ambient light.

First claim

What is claimed is:

1. A display apparatus comprising:
a sensor configured to sense ambient light;
a display configured to provide a screen including a first area which displays a content and a second area outside the first area; and
a processor configured to change a size of the second area based on the sensed ambient light,
wherein the processor is further configured to divide the second area into a plurality of edge areas based on the sensed ambient light and change respective sizes of the plurality of edge areas.

2. The apparatus as claimed in claim 1 , wherein the processor is further configured to reduce a size of at least one first edge area among the plurality of edge areas, the at least one first edge area being located in an incident direction of the sensed ambient light and enlarge a size of at least one second edge area among the plurality of edge areas, the at least one second edge area being located in a direction opposite to the incident direction of the sensed ambient light.

3. The apparatus as claimed in claim 2 , wherein the processor is further configured to change respective sizes of the at least one first edge area and the at least one second edge area based on an intensity of the sensed ambient light.

4. The apparatus as claimed in claim 2 , wherein the processor is further configured to reduce a size of the at least one first edge area and enlarge a size of the at least one second edge area while maintaining a size of the first area.

5. The apparatus as claimed in claim 1 , wherein the processor is further configured to divide the second area into the plurality of edge areas based on at least one among an intensity of the sensed ambient light and an incident direction of the sensed ambient light.

6. The apparatus as claimed in claim 5 , wherein the processor is further configured to determine a number of the plurality of edge areas based on the intensity of the sensed ambient light and determine boundaries of the plurality of edge areas based on the incident direction of the sensed ambient light.

7. The apparatus as claimed in claim 1 , wherein the processor is further configured to change a size of the second area in response to an intensity of the sensed ambient light being greater than a predetermined value.

8. The apparatus as claimed in claim 1 , wherein the processor is further configured to determine a change in a size of the second area based on an average luminance of the content.

9. A method of controlling a display apparatus, the method comprising:
providing a screen including a first area which displays a content and a second area outside the first area;
sensing ambient light; and
changing a size of the second area based on the sensed ambient light,
wherein the changing comprises dividing the second area into a plurality of edge areas based on the sensed ambient light and changing respective sizes of the plurality of edge areas.

10. The method as claimed in claim 9 , wherein the changing comprises reducing a size of at least one first edge area among the plurality of edge areas, the at least one first edge area being located in an incident direction of the sensed ambient light and enlarging a size of at least one second edge area among the plurality of edge areas, the at least one second edge area being located in a direction opposite to the incident direction of the sensed ambient light.

11. The method as claimed in claim 10 , wherein the changing comprises changing respective sizes of the at least one first edge area and the at least one second edge area based on an intensity of the sensed ambient light.

12. The method as claimed in claim 10 , wherein the changing comprises reducing a size of the at least one first edge area and enlarging a size of the at least one second edge area while maintaining a size of the first area.

13. The method as claimed in claim 9 , wherein the changing comprises dividing the second area into the plurality of edge areas based on at least one among an intensity of the sensed ambient light and an incident direction of the sensed ambient light.

14. The method as claimed in claim 13 , wherein the changing comprises determining a number of the plurality of edge areas based on the intensity of the sensed ambient light and determining boundaries of the plurality of edge areas based on the incident direction of the sensed ambient light.

15. The method as claimed in claim 9 , wherein the changing comprises changing a size of the second area in response to an intensity of the sensed ambient light being greater than a predetermined value.

16. The method as claimed in claim 9 , wherein the changing comprises determining a change in a size of the second area based on an average luminance of the content.

17. A non-transitory computer readable recording medium having embodied thereon a program, which when executed by a processor of a display apparatus causes the display apparatus to execute a method, the method including:
providing a screen including a first area which displays a content and a second area outside the first area;
sensing ambient light; and
changing a size of the second area based on the sensed ambient light,
wherein the changing comprises dividing the second area into a plurality of edge areas based on the sensed ambient light and changing respective sizes of the plurality of edge areas.
