[ METHOD EXAMPLE II ]
Referring to fig. 2, a flow chart illustrating specific steps of a method for protecting eyesight in an embodiment of the present invention is shown. The method comprises the following specific steps:
step 201: and detecting whether the mobile terminal is in a bright screen state.
In specific application, if the mobile terminal is detected to process the black screen state, the mobile terminal user does not operate the mobile terminal and does not need to execute any method for protecting eyesight; and if the mobile terminal is detected to be in the bright screen state, indicating that the mobile terminal user is likely to operate the mobile terminal, and starting the step of protecting eyesight.
Step 202: when the mobile terminal is in a bright screen state, detecting whether a face feature image exists in front of a screen of the mobile terminal through a front camera of the mobile terminal, and if the face feature image exists in front of the screen of the mobile terminal, acquiring the face feature image according to a first preset frequency.
In specific application, when a mobile terminal user uses the mobile terminal, the mobile terminal may be in a bright screen state due to misoperation, but the mobile terminal user does not really operate the mobile terminal at the moment, and if the eyesight protection step is started, the waste of electric quantity and resources of the mobile terminal is caused; therefore, whether the human face characteristic image exists in front of the screen of the mobile terminal can be further detected through the front camera of the mobile terminal.
When the mobile terminal is in a bright screen state and no human face characteristic image exists in front of a screen of the mobile terminal, the situation that a user of the mobile terminal does not operate the mobile terminal and does not need to execute any vision protection method is shown; if the mobile terminal is in a bright screen state and the face feature image exists in front of the screen of the mobile terminal, the step that the user of the mobile terminal may operate the mobile terminal and the eyesight can be protected is started.
In the embodiment of the invention, the step of judging whether the mobile terminal user is in the state of operating the mobile terminal is set before the step of collecting the face characteristic image according to the first preset frequency, specifically, the mobile terminal is detected to be in the bright screen state, and the face characteristic image exists in front of the screen of the mobile terminal, so that the user is judged to be in the state of operating the mobile terminal, the subsequent step of protecting the eyesight is started, and the loss of resources and electric quantity of the mobile terminal caused by the step of starting the method of protecting the eyesight due to the misoperation of the mobile terminal user can be avoided.
Step 203: and collecting a face characteristic image according to a first preset frequency.
As a preferable solution of the embodiment of the present invention, after step 203, the method may include the steps of: and determining a viewing position parameter between human eyes and a screen of the mobile terminal according to each human face feature image.
After determining the viewing position parameter between the human eyes and the screen of the mobile terminal according to each human face feature image, the method also comprises the following steps:
substep A1: and acquiring a difference value between the viewing position parameter and the previous viewing position parameter of the viewing position parameter every time one viewing position parameter is acquired.

Substep A2: when at least one difference value exceeds a preset difference threshold value, adjusting the first preset frequency to a second preset frequency; wherein the second preset frequency is greater than the first preset frequency.
In a specific application, the preset difference threshold may be set by a person skilled in the art according to an actual scenario. For example, if the viewing position parameter is a distance value, the preset difference threshold value may be set to 5cm, and if the difference value between two adjacent distance values is greater than 5cm, which indicates that the distance between the mobile terminal and the human eyes changes greatly at this time, the frequency of acquiring the facial feature images may be increased, and the first preset frequency is adjusted to a second preset frequency that is larger, so as to increase the number of times of analyzing the change of the distance value, so as to prompt the user to protect eyesight more timely or more accurately.
Substep A3: adjusting the first analysis period to a second analysis period; wherein the first analysis period is greater than the second analysis period.
In the embodiment of the invention, after the difference value of the parameters of two adjacent watching positions is detected to be larger than the preset difference threshold value, the frequency of acquiring the face characteristic image is accelerated, the analysis period is shortened, and the first analysis period is adjusted to be the second analysis period which is smaller, so that the user can be analyzed and prompted to protect eyesight in a shorter period.

Substep B2: if the mobile terminal is in a moving state and/or a shaking state, adjusting the first preset frequency to a second preset frequency; wherein the second preset frequency is greater than the first preset frequency.
In a specific application, if the mobile terminal is in a moving state and/or a shaking state, it indicates that the user may be in an unhealthy reading state, and the eyes of the user may be damaged for a long time, so that the first preset frequency may be increased, and then the operation of the above sub-step a3 is performed to prompt the user to protect the eyesight in time.
In order to clearly explain the present invention, the embodiment of the present invention takes the viewing position parameters including the distance value and the angle value as an example in the following steps, and the implementation process of each step is described in detail.
