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.

First claim

What is claimed is:

1 . A display apparatus comprising:
a display; a user input device configured to, in response to an input by a user, issue a command for executing a graphical user interface (GUI); and at least one processor configured to process a first image comprising at least one object to be displayed on the display, and process an image of the GUI corresponding to an outline of the at least one object to be displayed on the display, in response to receiving the command for executing the GUI from the user input device while the first image is displayed.

2 . The display apparatus according to claim 1 , wherein the at least one processor is configured to generate a second image corresponding to the outline of the at least one object by processing image information acquired from the first image, and process the second image to be displayed as a background image of the image of the GUI.

3 . The display apparatus according to claim 2 , wherein the at least one processor is configured to acquire the image information changed by continual reproduction of the first image in real time, and process the second image to be varied depending on the image information acquired in real time.

4 . The display apparatus according to claim 3 , wherein the at least one processor is configured to gradually change red, green, and blue (RGB) values of the second image so that the second 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 red, green, and blue (RGB) values of pixels included in an image frame of the first image.

6 . The display apparatus according to claim 5 , wherein the at least one processor is configured to generate the second image by dividing the image frame into sections, determining brightness and transparency values based on averaged RGB values of the pixels respectively included in corresponding divided sections, adjusting horizontal widths of the corresponding divided sections based on the determined brightness values, respectively, and applying blur filtering to the divided sections.

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

8 . The display apparatus according to claim 6 , wherein the corresponding divided sections are respectively surrounded by four edges including upper, lower, left, and right edges, and
the at least one processor is configured to apply the blur filtering to only the left edge and the right edge of the corresponding divided section.

9 . The display apparatus according to claim 1 , wherein the image of the GUI displays user interfaces (UIs) respectively corresponding to services provided by the display apparatus, and
the UIs are configured to be switched therebetween in response to the command issued by the user input device for indicating a direction of movement in one direction among up, down, left, and right directions, with respect to a screen of the display.

10 . The display apparatus according to claim 9 , wherein the at least one processor is configured to switch between the UIs of the services which are different from one another, in response to the command issued by the user input device 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 issued by the user input device for the movement in the left direction or the right direction.

11 . A method of controlling a display apparatus, the method comprising:
displaying a first image comprising at least one object; receiving a command for executing a graphical user interface (GUI), from a user input device, while displaying the first image; and displaying an image of the GUI corresponding to an outline of the at least one object.

12 . The method according to claim 11 , wherein the displaying the image of the GUI comprises:
generating a second image corresponding to the outline of the at least one object by processing image information acquired from the first image; and processing the second image to be displayed as a background image of the image of the GUI.

13 . The method according to claim 12 , wherein the displaying the GUI further comprises:
acquiring the image information changed by continual reproduction of the first image in real time; and processing the second image to be varied depending on the image information acquired in the real time.

14 . The method according to claim 13 , wherein the displaying the GUI further comprises:
gradually changing red, green, and blue (RGB) values of the second image so that the second image is changed with respect to a color over a time period.

15 . The method according to claim 12 , wherein the image information comprises red, green, and blue (RGB) values of pixels included in an image frame of the first image.

16 . The method according to claim 15 , wherein the generating the second image comprises:
dividing the image frame into sections; determining brightness and transparency values based on averaged RGB values of the pixels respectively included in corresponding divided sections; adjusting horizontal widths of the corresponding divided sections based on the determined brightness values, respectively; and applying blur filtering to the divided sections.

17 . The method according to claim 16 , wherein the adjusting the horizontal widths comprises:
adjusting the horizontal widths of the divided sections having higher brightness values to be more narrow; and adjusting the horizontal widths of the divided sections having lower brightness values to be wider.

18 . The method according to claim 16 , wherein the corresponding divided sections are respectively surrounded by four edges including upper, lower, left, and right edges, and the applying the blur filtering to the divided sections comprises applying the blur filtering to only the left edge and the right edge of the corresponding divided section.

19 . The method according to claim 11 , wherein the displaying the image of the GUI comprises displaying user interfaces (UIs) respectively corresponding to services provided by the display apparatus, and
the UIs are configured to be switched therebetween in response to the command received from the user input device indicating a direction of movement in one direction among up, down, left, and right directions, with respect to a display screen.

20 . The method according to claim 19 , further comprising:
switching between the UIs which provide the services different from one another, in response to the command received from the user input device for the movement in the up direction or the down direction; and switching between the UIs of a same service, in response to the command issued by the user input device for the movement in the left direction or the right direction.
