Abstract

A display apparatus and a control method thereof are provided. The display apparatus may include a memory configured to store data related to a background image of an area behind the display apparatus, a display configured to display content by overlaying the content onto the background image, a sensor configured to generate sensing data related to external light that is ambient to the display apparatus, and a processor configured to perform image-processing of at least one of the background image and the content, based on a type of the content and the sensing data.

Claims

1. A display apparatus comprising:

a memory configured to store data related to a background image of an area behind the display apparatus;

a display configured to display content by overlaying the content onto the background image;

a sensor configured to generate sensing data related to external light ambient to the display apparatus; and

a processor configured to perform image-processing of at least one of the background image and the content, based on a type of the content and the sensing data.

2. The display apparatus of claim 1, wherein the processor is further configured to perform image-processing of the background image based on the sensing data, and determine whether to perform image-processing of the content based on the type of the content.

3. The display apparatus of claim 1, wherein the processor is further configured to perform image-processing of the background image based on the sensing data, and determine whether to perform image-processing of the content based on the image-processed background image and the type of the content.

4. The display apparatus of claim 1, wherein the processor is further configured to perform image-processing of the background image based on the sensing data, and perform image-processing of the content based on the image-processed background image and the type of the content.

5. The display apparatus of claim 1, wherein the sensor is further configured to generate the sensing data related to at least one of a brightness and a color temperature of the external light, and

wherein the processor is further configured to change a contrast of at least one of the background image and the content based on the brightness, and change a white balance of at least one of the background image and the content based on the color temperature.

6. The display apparatus of claim 5, wherein the processor is further configured to, if at least one of the brightness and the color temperature changes by at least a threshold value, perform the image-processing for a period of time.

7. The display apparatus of claim 1, further comprising:

a video processor configured to recover encoded data by decoding the data,

wherein the processor comprises a graphic processor configured to perform graphic-processing of input data, and

wherein the processor is further configured to allocate the background image and the content to the graphic processor and the video processor, and the graphic processor and the video processor are further configured to perform image-processing of the allocated background image and the allocated content.

8. The display apparatus of claim 7, wherein the processor is further configured to allocate the content to one of the graphic processor and the video processor based on the type of the content, and allocate the background image to the other one of the graphic processor and the video processor.

9. The display apparatus of claim 1, wherein the processor is further configured to, if a first resolution rate of the content is different from a second resolution rate of the display, control the display to display the background image on a portion of an area on which the content is displayed.

10. A control method of a display apparatus, the control method comprising:

storing data related to a background image of an area behind the display apparatus;

displaying content by overlapping the content onto the background image;

generating sensing data related to external light that is ambient to the display apparatus; and

performing image-processing of at least one of the background image and the content, based on a type of the content and the sensing data.

11. The control method of claim 10, wherein the performing image-processing comprises performing image-processing of the background image based on the sensing data, and determining whether to perform image-processing of the content based on the type of the content.

12. The control method of claim 10, wherein the performing image-processing comprises performing image-processing of the background image based on the sensing data, and determining whether to perform image-processing of the content based on the image-processed background image and the type of the content.

13. The control method of claim 10, wherein the performing image-processing comprises performing image-processing of the background image based on the sensing data, and performing image-processing of the content based on the image-processed background image and the type of the content.

14. The control method of claim 10, wherein the generating sensing data comprises generating the sensing data related to at least one of a brightness and a color temperature of the external light, and

wherein the performing image-processing comprises changing a contrast of at least one of the background image and the content based on the brightness, and changing a white balance of at least one of the background image and the content based on the color temperature.

15. The control method of claim 14, wherein the performing image-processing comprises, if at least one of the brightness and the color temperature changes by at least a threshold value, performing the image-processing for a period of time.

16. The control method of claim 10, wherein the display apparatus comprises a graphic processor configured to perform graphic-processing of input data and a video processor configured to recover encoded data by decoding the data, and

wherein the performing image-processing comprises allocating the background image and the content to the graphic processor and the video processor, and performing, by the graphic processor and the video processor, image-processing of the allocated background image and the allocated content.

17. The control method of claim 16, wherein the performing image-processing comprises allocating the content to one of the graphic processor and the video processor based on the type of the content and allocating the background image to the other one of the graphic processor and the video processor.

18. The control method of claim 10, wherein the displaying content comprises if a first resolution rate of the content is different from a second resolution rate of the display, displaying the background image on a portion of an area on which the content is displayed.

19. A non-transitory recording medium in which a program for performing an operation method of a display apparatus is stored, the operation method comprising:

storing data related to a background image of an area behind the display apparatus;

displaying content by overlapping the content onto the background image;
