Abstract

A first display apparatus includes a display; a communicator configured to communicate with a second display apparatus; and a processor configured to: display an image on the display, obtain a first ambient light value of a first ambient light of the first display apparatus, receive a second ambient light value of a second ambient light of the second display apparatus and a second image-quality value of the second display apparatus through the communicator, and adjust a first image-quality value of the displayed image based on the second image-quality value and the first ambient light value, by using a relationship between the second ambient light value of the second ambient light and the second image-quality value of the second display apparatus.

Claims

1. A first display apparatus, comprising:

a display;

a communicator configured to communicate with a second display apparatus; and

a processor configured to;

display an image on the display,

obtain a first ambient light value of a first ambient light of the first display apparatus,

receive a second ambient light value of a second ambient light of the second display apparatus and a second image-quality value of the second display apparatus through the communicator, and

adjust a first image-quality value of the displayed image based on the second image-quality value and the first ambient light value, by using a relationship between the second ambient light value of the second ambient light and the second image-quality value of the second display apparatus.

2. The first display apparatus according to claim 1, wherein the first ambient light value and/or the second ambient light value comprises at least one of an illumination value or a color temperature value of the first ambient light and/or the second ambient light.

3. The first display apparatus according to claim 1, wherein the processor is further configured to adjust the first image-quality value by changing at least one of brightness or a gamma curve of the displayed image.

4. The first display apparatus according to claim 1, wherein the processor is further configured to adjust the first image-quality value with reference to a table in which a plurality of preset image-quality values are tabulated corresponding to a plurality of ambient light values.

5. The first display apparatus according to claim 1, wherein the processor is further configured to adjust the first image-quality value by using a preset function or a preset algorithm based on a relationship between an ambient light value and an image-quality value.

6. The first display apparatus according to claim 1, wherein the processor is further configured to receive a user input value for the first ambient light from the second display apparatus, through the communicator.

7. The first display apparatus according to claim 1, wherein the processor is further configured to:

display a user interface (UI) comprising a plurality of selectable menu items about information of the first ambient light, and

receive, through the user interface, a user input value among the plurality of selectable menu items, and determine the first ambient light value of the first ambient light based on the user input value.

8. The first display apparatus according to claim 1, wherein the processor is further configured to receive the first ambient light value of the first ambient light from a server through the communicator.

9. The first display apparatus according to claim 1, wherein the processor is further configured to selectively perform adjustment of the first image-quality value based on whether a difference between the first ambient light value of the first ambient light and the received second ambient light value of the second ambient light is greater than a threshold apparatus.

10. The first display apparatus according to claim 1, wherein the processor is further configured to selectively perform adjustment of the first image-quality value based on whether a current time is in a preset timeslot.

11. The first display apparatus according to claim 1, further comprising a user input interface, wherein the processor is further configured to:

adjust a third image-quality value of a second image displayed on the display based on a user input received through the user input interface, and

transmit, to the second display apparatus through the communicator, the adjusted third image-quality value of the second image and a third ambient light value of the first ambient light of the first display apparatus detected while displaying the second image.

12. The first display apparatus according to claim 1, further comprising a sensor configured to detect the first ambient light value of the first ambient light of the first display apparatus.

13. A display system, comprising:

a first display apparatus; and

a second display apparatus placed in a different display environment from that of the first display apparatus,

the first display apparatus comprising;

a first display;

a first communicator configured to communicate with the second display apparatus;

a first sensor configured to detect a first ambient light of the first display apparatus;

a first user input interface; and

a first processor configured to;

display a first image on the first display,

adjust a first image-quality value of the displayed first image based on a user input received through the first user input interface, and

transmit the adjusted first image-quality value and a first ambient light value of the detected first ambient light to the second display apparatus through the first communicator, and

the second display apparatus comprising;

a second display;

a second communicator configured to communicate with the first display apparatus;

a second sensor configured to detect a second ambient light of the second display apparatus;

a second processor configured to;

receive the adjusted first image-quality value and the first ambient light value of the first display apparatus through the second communicator, and

adjust a second image-quality value of a second image displayed on the second display based on the first image-quality value and a second ambient light value of the second ambient light of the second display apparatus, by using a relationship between the first ambient light value of the first ambient light and the first image-quality value of the first display apparatus.

14. The display system according to claim 13, wherein the first ambient light value and/or the second ambient light value comprises at least one of an illumination value or a color temperature value of the first ambient light and/or the second ambient light.

15. The display system according to claim 13, wherein the first processor and/or the second processor is further configured to adjust the first image-quality value and/or the second image-quality value by changing at least one of brightness or a gamma curve of the first image or the second image.

16. The display system according to claim 13, wherein the first processor and/or the second processor is further configured to adjust the first image-quality value and/or the second image-quality value with reference to a table in which a plurality of preset image-quality values are tabulated corresponding to a plurality of ambient light values.

17. The display system according to claim 13, wherein the first processor and/or the second processor is further configured to adjust the first image-quality value and/or the second image-quality value by using a preset function or a preset algorithm based on a relationship between an ambient light value and an image-quality value.

18. A method of controlling a first display apparatus, the method comprising:

displaying an image on the first display apparatus;

obtaining a first ambient light value of a first ambient light of the first display apparatus;
