Abstract

An eye protecting method in an electronic device with storage device determines eyesight of a user who is using an electronic device, acquires light intensity of the environment, and distance of eyes of a user from the device, and applies a preferred display brightness value which is associated with the readings. The method may also cause display of warnings to the user as to eye-distance from the device and current time period spent watching the device.

Claims

1. An electronic device comprising:

at least one processor;

a display device electrically coupled to the processor; and

a storage device electrically coupled to the processor and storing instructions for execution by the processor to cause the processor to;

determine eyesight of a user who is using the electronic device;

acquire light intensity of the current environment of the electronic device by a light detecting device;

acquire a display brightness value, according to the eyesight of the user, the current light intensity, and a relationship among the light intensity values, the eyesight of the user, and the display brightness values of the display device; and

adjust the display brightness of the display device to the acquired display brightness value.

2. The electronic device according to claim 1, wherein the at least one processor is further caused to:

control a capturing device to capture a facial image of the user;

identify the captured facial image of the user; and

acquire, when the facial image of the user is verified, the eyesight associated with the verified facial image.

3. The electronic device according to claim 1, wherein the at least one processor is further caused to:

acquire fingerprint information of the user by a fingerprint acquiring device;

identify the acquired fingerprint information of the user; and

acquire, when the fingerprint information of the user is verified, the eyesight associated with the verified fingerprint information.

4. The electronic device according to claim 2, wherein the at least one processor is further caused to:

acquire an eye image from the facial image captured by the capturing device;

recognize a pupil area in the eye image;

calculate the pupil size; and

determine the eyesight according to the pupil size.

5. The electronic device according to claim 1, wherein the at least one processor is further caused to:

acquire a distance between the eyes of the user and the electronic device by a distance detecting device every predetermined time period;

determine whether the distance between the eyes of the user and the electronic device is less than a predetermined distance; and

control, when determining that the distance between the eyes of the user and the electronic device is less than the predetermined distance, the electronic device to output a message to prompt the user to consider the distance to the electronic device or turn off the display device.

6. The electronic device according to claim 1, wherein the at least one processor is further caused to:

record current usage of the electronic device;

determine whether the user continues using the electronic device according to the current usage of the electronic device; and

control, when determining that the user does not continue using the electronic device, the electronic device to output a message to prompt the user to stop using the electronic device.

7. The electronic device according to claim 6, wherein the usage of the electronic device comprises a duration of using the electronic device, a duration of using a designated application, and a duration or plurality of times that the distance between the eyes of the user and the electronic device is less than the predetermined distance.

8. An eye protecting method comprising:

determining eyesight of a user who is using an electronic device;

acquiring light intensity of the current environment of the electronic device by a light detecting device;

acquiring a display brightness value, according to the eyesight of the user, the current light intensity, and a relationship among the light intensity values, the eyesight of the user, and the display brightness values of a display device; and

adjusting the display brightness of the display device to the acquired display brightness value.

9. The eye protecting method according to claim 8, further comprising:

controlling a capturing device to capture a facial image of the user;

identifying the captured facial image of the user; and

acquiring the eyesight associated with the verified facial image when the facial image of the user is verified.

10. The eye protecting method according to claim 8, further comprising:

acquiring fingerprint information of the user by a fingerprint acquiring device;

identifying the acquired fingerprint information of the user; and

acquiring the eyesight associated with the verified fingerprint information when the fingerprint information of the user is verified.

11. The eye protecting method according to claim 9, further comprising:

acquiring an eye image from the facial image captured by the capturing device;

recognizing a pupil area in the eye image;

calculating the pupil size; and

determining the eyesight according to the pupil size.

12. The eye protecting method according to claim 8, further comprising:

acquiring a distance between the eyes of the user and the electronic device by a distance detecting device every predetermined time period;

determining whether the distance between the eyes of the user and the electronic device is less than a predetermined distance; and

controlling the electronic device to output a message to prompt the user to consider the distance to the electronic device or turn off the display device when determining that the distance between the eyes of the user and the electronic device is less than the predetermined distance.

13. The eye protecting method according to claim 8, further comprising:

recording current usage of the electronic device;

determining whether the user continues using the electronic device according to the current usage of the electronic device; and

controlling the electronic device to output a message to prompt the user to stop using the electronic device when determining that the user does not continue using the electronic device.

14. The eye protecting method according to claim 13, wherein the usage of the electronic device comprises a duration of using the electronic device, a duration of using a designated application, and a duration or plurality of times that the distance between the eyes of the user and the electronic device is less than the predetermined distance.
