Abstract

A display apparatus including: a display; a user input configured to issue a command for executing a GUI; and a processor configured to process a first image including an object to be displayed on the display, and process the GUI corresponding to an outline of the object to be displayed on the display in response to receiving the command for executing the GUI from the user input while the first image is displayed.

Claims

1. A display apparatus comprising:

a display;

a tuner configured to receive a broadcast signal;

an input unit; and

a processor configured to;

process the broadcast signal received from the tuner,

control the display to display a moving video image comprising a plurality of image frames based on the processed broadcast signal,

based on a user input for displaying a menu graphical user interface (GUI) being received, obtain an image frame from among the plurality of image frames,

divide the obtained image frame into a plurality of sections,

adjust horizontal widths of each of the plurality of sections based on red, green, and blue (RGB) values of pixels in each of the plurality of sections,

apply blur filtering to the plurality of sections having the adjusted horizontal widths, and

control the display to display the menu GUI on a background image comprising the plurality of sections to which the blur filtering is applied,

wherein the background image is generated in real time based on the plurality of image frames.

2. The display apparatus according to claim 1, wherein the processor is further configured to generate the background image by processing image information acquired from the moving video image.

3. The display apparatus according to claim 2, wherein the processor is further configured to acquire the image information changed by continual processing of the moving video image in the real time, and process the background image to be varied depending on the image information acquired in the real time.

4. The display apparatus according to claim 3, wherein the processor is further configured to gradually change the RGB values of the background image so that the background image is changed with respect to a color over a time period.

5. The display apparatus according to claim 2, wherein the image information comprises the RGB values of pixels included in image frames of the moving video image.

6. The display apparatus according to claim 5, wherein the processor is further configured to generate the background image by determining brightness values and transparency values based on averaged RGB values of pixels respectively included in the plurality of sections, and adjusting the horizontal widths of the plurality of sections based on the brightness values, respectively.

7. The display apparatus according to claim 6, wherein the processor is further configured to adjust the horizontal widths of the plurality of sections having higher brightness values to be more narrow, and to adjust the horizontal widths of the plurality of sections having lower brightness values to be wider.

8. The display apparatus according to claim 6, wherein each of the plurality of sections is surrounded by edges including an upper edge, a lower edge, a left edge, and a right edge, and

the processor is further configured to apply the blur filtering to the left edge and the right edge of the plurality of sections, respectively.

9. The display apparatus according to claim 1, wherein the processor is further configured to control the display to display, on the menu GUI, user interfaces (UIs) respectively corresponding to services provided by the display apparatus, and

the UIs are configured to be switched therebetween in response to a command received through the input unit for indicating a direction of a movement in one direction among an up direction, a down direction, a left direction, and a right direction, with respect to a screen of the display.

10. The display apparatus according to claim 9, wherein the processor is further configured to switch between the UIs of the services which are different from one another, in response to the command received through the input unit for the movement in the up direction or the down direction, and switch between the UIs of a same service in response to the command received through the input unit for the movement in the left direction or the right direction.

21. The display apparatus according to claim 1, wherein the background image is seen through the displayed menu GUI having a transparency.

22. The display apparatus according to claim 1, wherein the processor is further configured to adjust the horizontal widths of first sections, among the plurality of sections, that include the RGB values of pixels with a greater brightness to be smaller than the horizontal widths of second sections, among the plurality of sections, that include the RGB values of pixels with a lower brightness.

11. A method of controlling a display apparatus comprising a display and a tuner configured to receive a broadcast signal, the method comprising:

processing the received broadcast signal;

displaying a moving video image comprising a plurality of image frames based on the processed broadcast signal,

based on a user input for displaying a menu graphical user interface (GUI) being received, obtaining an image frame from among the plurality of image frames,

dividing the obtained image frame into a plurality of sections,

adjusting horizontal widths of each of the plurality of sections based on red, green, and blue (RGB) values of pixels in each of the plurality of sections,

applying blur filtering to the plurality of sections having the adjusted horizontal widths, and

displaying the menu GUI on a background image comprising the plurality of sections to which the blur filtering is applied,

wherein the background image is generated in real time based on the plurality of image frames.

12. The method according to claim 11, wherein the obtaining the image frame comprises:

processing image information acquired from the moving video image.

13. The method according to claim 12, further comprising:

acquiring the image information changed by continual processing of the moving video image in the real time; and

processing the background image to be varied depending on the image information acquired in the real time.

14. The method according to claim 13, further comprising:

gradually changing the RGB values of the background image so that the background image is changed with respect to a color over a time period.

15. The method according to claim 12, wherein the image information comprises the RGB values of pixels included in image frames of the moving video image.

16. The method according to claim 15, wherein the adjusting the horizontal widths further comprises:

determining brightness values and transparency values based on averaged RGB values of pixels respectively included in the plurality of sections; and

adjusting the horizontal widths of the plurality of sections based on the brightness values, respectively.

17. The method according to claim 16, wherein the adjusting the horizontal widths further comprises:

adjusting the horizontal widths of the plurality of sections having higher brightness values to be more narrow; and

adjusting the horizontal widths of the plurality of sections having lower brightness values to be wider.

18. The method according to claim 16, wherein each of the plurality of sections is surrounded by edges including an upper edge, a lower edge, a left edge, and a right edge, and
