Abstract

A display apparatus includes: a display configured to display an image; an image processor configured to process the displayed image; and a controller configured to control the image processor to adjust a blue (B) value of red (R), green (G), and B values constituting the image based on at least one of information about a user and information about a viewing habits of the user.

Claims

1. A display apparatus comprising:

a display configured to display an image;

a controller which adjusts a blue (B) value of red (R), green (G), and B values constituting the image according to a current elapsed viewing time of a user,

wherein the controller measures the current elapsed viewing time counted by a timer and controls to decrease the blue value as the current elapsed viewing time increases, and

wherein the controller compares the measured current elapsed viewing time with a preset viewing time, and if the measured current elapsed viewing time exceeds the preset viewing time, controls to increase a decrement of the blue value.

2. The display apparatus of claim 1, wherein the controller reduces the B value of the R, G, and B values in real time based on the current elapsed viewing time.

3. The display apparatus of claim 1, wherein the controller reduces the R, G, and B values into a spectral distribution and adjusts a wavelength value corresponding to the B value.

4. The display apparatus of claim 1, wherein the controller detects a preset object of the image and adjusts the B value of the R, G, and B values corresponding to the image except the detected preset object.

5. The display apparatus of claim 1, wherein the controller further adjusts the B value based on at least one of a viewing position of the user, and a viewing posture of the user.

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

a user interface (UI),

wherein the controller adjusts the B value of the R, G, and B values based on time information input through the UI.

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

adjusting, by a controller, a blue (B) value of red (R), green (G), and B values constituting an image according to a current elapsed viewing time of a user; and

displaying, by a display, the image having the adjusted B value,

wherein the adjusting further comprises measuring the current elapsed viewing time counted by a timer and controlling to decrease the blue value as the current elapsed viewing time increases,

wherein the controlling comprises comparing the measured current elapsed viewing time with a preset viewing time and if the measured current elapsed viewing time exceeds the preset viewing time, controlling to increase a decrement of the blue value.

8. The method of claim 7, wherein the B value of the R, G, and B values is adjusted in real time to be reduced based on the current elapsed viewing time.

9. The method of claim 7, wherein the R, G, and B values are converted into a spectral distribution, and then a wavelength value of the B value is adjusted.

10. The method of claim 7, wherein a preset object of the image is detected, and the B value of the R, G, and B values corresponding to the image except the detected preset object is adjusted.

11. The method of claim 7, wherein the adjusting further comprises adjusting the B value based on at least one of a viewing position of the user, and a viewing posture of the user.

12. The method of claim 7, further comprising:

receiving time information on a user interface (UI); and

adjusting, by a controller, the B value of the R, G, and B values based on the time information.

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

adjusting, by a controller, a blue (B) value from among red (R), green (G), and B values of an image according to a current elapsed viewing time of a user; and

displaying, by a display, the image having the adjusted B value,

wherein the adjusting further comprises measuring the current elapsed viewing time counted by a timer and controlling to decrease the blue value as the current elapsed viewing time increases, and

wherein the controlling comprises comparing the measured current elapsed viewing time with a preset viewing time and, if the measured current elapsed viewing time exceeds the preset viewing time, controlling to increase a decrement of the blue value.

14. The method of claim 13, wherein the R, G, and B values are converted into a spectral distribution, and then a wavelength value of the B value is adjusted.

15. The method of claim 13, wherein a preset object of the image is detected, and the B value of the R, G, and B values corresponding to the image except the detected preset object is adjusted.

16. The method of claim 13, wherein the adjusting further comprises adjusting the B value based on at least one of a viewing position of the user, and a viewing posture of the user.

17. A non-transitory computer readable medium comprising instructions executable by a computer to perform the method of claim 13.
