Abstract

Embodiments of the present disclosure relate to the field of display technologies, and disclose a method and device for adjusting screen luminance, and a display device that includes the device for adjusting screen luminance. According to the present disclosure, screen luminance may be adjusted directly according to the eye comfort degree so as to achieve the objective of protecting eyes. The method for adjusting screen luminance includes: detecting a pupil size of a user; and adjusting the screen luminance according to the pupil size, such that the adjusted luminance is in a range within which human eyes are comfortable.

Claims

1. A method for adjusting screen luminance, applied in a terminal, comprising:

detecting a pupil size of a user; and

adjusting the screen luminance according to the pupil size, such that the adjusted luminance is in a range within which human eyes are comfortable.

2. The method according to claim 1, wherein the adjusting the screen luminance according to the pupil size comprises:

comparing the pupil size with a pupil size conversion range table, wherein the pupil size conversion range table stores a correspondence between luminance and a pupil size of human eyes under the luminance;

determining whether luminance corresponding to the pupil size is in the range within which human eyes are comfortable; and

when the luminance is not in the range within which human eyes are comfortable, adjusting the screen luminance to make the adjusted luminance located in the range within which human eyes are comfortable.

3. The method according to claim 1, wherein when the luminance is not in the range within which human eyes are comfortable, the adjusting the screen luminance comprises:

determining whether the luminance is too dark or too bright; and

when the luminance is too dark, increasing the screen luminance until the luminance corresponding to the detected pupil size is in the range within which human eyes are comfortable;

or

when the luminance is too bright, reducing the screen luminance until the luminance corresponding to the detected pupil size is in the range within which human eyes are comfortable.

4. The method according to claim 1, wherein after the screen luminance is adjusted, the method further comprises:

receiving an instruction of the user for adjusting the screen luminance; and

adjusting the screen luminance according to the instruction of the user for adjusting the screen luminance.

5. The method according to claim 1, wherein the method further comprises:

associating the screen luminance adjusted according to the instruction of the user for adjusting the screen luminance with an initially detected pupil size, and storing same.

6. The method according to claim 1, wherein the adjusting the screen luminance according to the pupil size comprises:

when the detected pupil size is same as the pupil size on which associative storage is performed, adjusting the screen luminance to the screen luminance on which associative storage is performed.

7. A non-volatile computer storage medium, which stores a computer executable instructions, wherein the computer executable instruction is set as:

detecting a pupil size of a user; and

adjusting the screen luminance according to the pupil size, so that the adjusted luminance is in a range in which human eyes are comfortable.

8. The non-transitory computer-readable storage medium according to claim 7, wherein the adjusting the screen luminance according to the pupil size comprises:

comparing the pupil size with a pupil size conversion range table, wherein the pupil size conversion range table stores a correspondence between luminance and a pupil size of human eyes under the luminance;

determining whether luminance corresponding to the pupil size is in the range in which human eyes are comfortable; and

in a case in which the luminance is not in the range in which human eyes are comfortable, adjusting the screen luminance to make the adjusted luminance located in the range in which human eyes are comfortable.

9. The non-transitory computer-readable storage medium according to claim 7, wherein in a case in which the luminance is not in the range in which human eyes are comfortable, adjusting the screen luminance comprises:

determining whether the luminance is too dark or too bright; and

in a case in which the luminance is too dark, increasing the screen luminance until the luminance corresponding to the detected pupil size is in the range in which human eyes are comfortable;

or

in a case in which the luminance is too bright, reducing the screen luminance until the luminance corresponding to the detected pupil size is in the range in which human eyes are comfortable.

10. The non-transitory computer-readable storage medium according to claim 7, wherein after the screen luminance is adjusted, the method further comprises:

receiving an instruction of the user for adjusting the screen luminance; and

according to the instructions of the user for adjusting the screen luminance, adjusting the screen luminance.

11. The non-transitory computer-readable storage medium according to claim 7, wherein the non-volatile computer storage medium further comprises:

associating the screen luminance adjusted according to the instruction of the user for adjusting the screen luminance with an initially detected pupil size, and storing same.

12. The non-transitory computer-readable storage medium according to claim 7, wherein the adjusting the screen luminance according to the pupil size comprises:

in a case in which the detected pupil size is same as the pupil size on which associative storage is performed, adjusting the screen luminance to the screen luminance on which associative storage is performed.

13. An electronic device, comprising:

at least one processor;

and a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, where execution of the instructions by the at least one processor causes the at least one processor to be capable of;

detecting a pupil size of a user; and

adjusting the screen luminance according to the pupil size, so that the adjusted luminance is in a range in which human eyes are comfortable.

14. The electronic device according to claim 13, wherein the adjusting the screen luminance according to the pupil size comprises:

comparing the pupil size with a pupil size conversion range table, wherein the pupil size conversion range table stores a correspondence between luminance and a pupil size of human eyes under the luminance;

determining whether luminance corresponding to the pupil size is in the range in which human eyes are comfortable; and

in a case in which the luminance is not in the range in which human eyes are comfortable, adjusting the screen luminance to make the adjusted luminance located in the range in which human eyes are comfortable.

15. The electronic device according to claim 13, wherein in a case in which the luminance is not in the range in which human eyes are comfortable, adjusting the screen luminance comprises:

determining whether the luminance is too dark or too bright; and

in a case in which the luminance is too dark, increasing the screen luminance until the luminance corresponding to the detected pupil size is in the range in which human eyes are comfortable;

or

in a case in which the luminance is too bright, reducing the screen luminance until the luminance corresponding to the detected pupil size is in the range in which human eyes are comfortable.

16. The electronic device according to claim 13, wherein after the screen luminance is adjusted, the method further comprises:

receiving an instruction of the user for adjusting the screen luminance; and

according to the instruction of the user for adjusting the screen luminance, adjusting the screen luminance.

17. The electronic device according to claim 13, wherein the electronic device further comprises:

associating the screen luminance adjusted according to the instruction of the user for adjusting the screen luminance with an initially detected pupil size, and storing same.
