Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0025] Current research shows that when the light increases, the pupil diameter of the normal human eye will decrease, and when the light decreases, the pupil diameter will increase. Even if the change in light is so weak that the visual center of the brain cannot perceive it, the size of the pupil diameter will change. If the eyes are in a state of fatigue, the degree to which a person's pupil diameter changes due to changes in light will be exacerbated. According to the test, in normal environment, the frequency of change of pupil diameter of a person in a normal state (non-fatigue state) averages 5 to 10 times per minute. Up to 15 times per minute. In other words, when the pupil diameter change frequency exceeds 10 times, the human eye is already in a state of fatigue, and when it is close to 15 times, it is already in a very fatigued state.

Abstract

The invention provides a visual fatigue detection and mitigation method which is characterized by comprising the following steps: diameter values of pupils of a user are detected; change frequency of the pupil diameters of the user is detected; and when the change frequency of the pupil diameters of the user surpasses a predetermined frequency value, a display parameter of a screen watched by the user is adjusted. The change frequency of the pupil diameters of the user is detected, and the change frequency of the pupil diameters is compared with the predetermined frequency value indicating visual fatigue so that the visual fatigue situation of the user can be accurately mastered, the screen display parameter of a device watched by the user can be timely adjusted and thus visual fatigue of the user is mitigated.

Description

technical field [0001] The present invention relates to a method for detecting and mitigating visual fatigue, in particular to a method for relieving visual fatigue by controlling the screen display parameters of the electronic equipment used by the user after detecting the visual fatigue state of the user's eyes through a front camera when using an electronic device How to detect and relieve eye fatigue. Background technique [0002] At present, electronic equipment is an indispensable part in people's life and work, such as mobile phones and computers. However, when using mobile phones and computers for a long time, eye fatigue will occur. Especially for office workers who often use computers, they need to stare at the computer screen for a long time during work, and also stare at the mobile phone screen when they are free, which will definitely cause eye fatigue. [0003] But in general, it is difficult for users to feel it when their eyes are tired, and they will not f...
