Abstract

A display apparatus, including a display configured to display an image, at least one sensor configured to generate sensing data relating to at least one from among a direction and an intensity of external light projected onto the display from an external light source disposed around the display, a memory configured to store background image data relating to a background image of a background area behind the display, and a processor configured to generate a content screen based on the background image data and the sensing data and control the display to display the content screen, wherein the content screen may include at least one graphic object and a shadow corresponding to the at least one graphic object disposed on the background image, and at least one of a position and a shade of the shadow is changed in response to a change in the sensing data.

Claims

1. A display apparatus comprising:

a display;

at least one sensor configured to generate sensing data relating to at least one from among a direction and an intensity of external light projected onto the display from an external light source disposed around the display;

a memory storing background image data relating to a background image of a background area behind the display; and

a processor configured to;

generate a content screen based on the background image data and the sensing data and

control the display to display the content screen,

wherein the content screen comprises at least one graphic object and a shadow corresponding to the at least one graphic object disposed on the background image, and a position of the shadow is changed according to a change of the direction of the external light based on the sensing data.

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

a bezel disposed at an edge of the display; and

an outer frame configured to cover the bezel,

wherein the processor is further configured to control the display to display an outer frame shadow in an area at an edge of the content screen, the edge corresponding to the outer frame.

3. The display apparatus of claim 1, wherein the content screen comprises an object layer including the at least one graphic object, a shadow layer including the shadow, and a background image layer including the background image.

4. The display apparatus of claim 3, wherein the processor is further configured to control the display to sequentially arrange the background image layer, the shadow layer, and the object layer, so that the object layer, the shadow layer, and the background image layer are sequentially displayed from a front position.

5. The display apparatus of claim 1, wherein the processor is further configured to perform an image correction with respect to the at least one graphic object according to at least one of the direction and the intensity of the external light sensed by the at least one sensor.

6. The display apparatus of claim 5, wherein in response to a plurality of graphic objects being included in the content screen, the processor is further configured to perform a plurality of image corrections with respect to the plurality of graphic objects according to a plurality of types of the plurality of graphic objects.

7. The display apparatus of claim 1, wherein the processor is further configured to generate the shadow based on whether the background image includes a pattern.

8. The display apparatus of claim 1, wherein the processor is further configured to operate in one of a background mode and a normal mode, and to control the display to display a content screen including the background image while operating in the background mode.

9. The display apparatus of claim 1, wherein the memory is further configured to store position data relating to a first area of the background image, the first area being surrounded by a second area including a first image pattern,

wherein the processor is further configured to extract a third area, which includes a second image pattern matching the first image pattern, from the background image, based on the position data relating to the first area, determine a fourth area corresponding to the first area in the background image based on the extracted third area, and control the display to display a corrected background image in which the first area is replaced by the fourth area.

10. The display apparatus of claim 9, wherein the background image comprises a repeated image pattern that is repeated at least twice,

wherein the first area is at least one area selected by a user.

11. The display apparatus of claim 9, wherein the processor is further configured to determine an area excluding the first area as the second area.

12. The display apparatus of claim 9, wherein the processor is further configured to extract the third area, from the background image as a result of determining that the first image pattern matches the second image pattern using feature information of the first image pattern.

13. The display apparatus of claim 9, wherein the processor is further configured to calculate brightness data of the second area, and to correct a brightness of the fourth area based on the calculated brightness data.

14. The display apparatus of claim 13, wherein the processor is further configured to apply a blending effect based on the corrected brightness of the fourth area and the brightness data of the second area.

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

a communicator configured to perform a data communication with an electronic device,

wherein in response to correction data of the background image being received from the electronic device, the processor is further configured to correct the background image based on the received correction data.

16. The display apparatus of claim 15, wherein the correction data is generated by comparing a display area displaying the background image with a surrounding area in an correction image acquired by capturing an area comprising the display apparatus displaying the background image.

17. The display apparatus of claim 16, wherein the correction data comprises a correction value for matching a pixel value of the display area with a pixel value of the surrounding area by comparing the pixel value of the display area and the pixel value of the surrounding area.

18. The display apparatus of claim 16, wherein the correction data comprises a correction value for matching a first pixel value of at least one pixel included in a preset first area of the display area with a second pixel value of at least one pixel included in a preset second area of the surrounding area, by comparing the first pixel value with the second pixel value.

19. The display apparatus of claim 16, wherein the correction image comprises indicators for identifying the display apparatus, and distinguishing the display area displaying the background image from the surrounding area.

20. The display apparatus of claim 16, wherein in response to re-correction data relating to the corrected background image being received, the processor is further configured to re-correct the corrected background image based on the received re-correction data.

21. The display apparatus of claim 1, wherein a shade of the shadow is changed according to a change of the intensity of the external light based on the sensing data.
