Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.

Referring to Fig.1, a kind of step flow chart of screen luminance adjustment method of the embodiment of the present invention is shown, it specifically can be with Include the following steps:

Step 101, the pupil diameters of active user are obtained.

User pass through mobile terminal reading electronic book during, if reading time it is too long will lead to user eye it is tired The pupil size of labor, user changes.Correspondingly, mobile terminal is available and pupil size according to user, determines and use Whether family is in asthenopia state, then can be according to the pupil size of user, to screen when user is in asthenopia state Brightness is adjusted.

Therefore, before the brightness of screen is adjusted in mobile terminal, need to obtain the pupil diameters of active user, with Just in the next steps, it can determine whether user is in asthenopia state, and then right according to the pupil diameters of the user of acquisition The screen intensity of mobile terminal is adjusted.

Specifically, mobile terminal can acquire the eyes image of user, and to eye by pre-set front camera Portion's image is identified, the eyeball image of user is obtained, and is analyzed finally by bright pupil hole and dark pupil technology, extraction obtains Pupil in eyeball image finally obtains the diameter of pupil, then can be using the diameter of the pupil as active user Pupil diameters.

Correspondingly, mobile terminal obtain user pupil diameters while, can also be bright according to the screen of mobile terminal The environment spent and be currently located obtains current screen parameter and current environment parameter, by the pupil diameters of active user, current screen Curtain parameter and current environment parameter are as current reading parameters.

Step 102, judge the difference between the pupil diameters of user and default pupil diameters, if be greater than default error threshold Value.

Mobile terminal can preset the pupil diameters of user with what is obtained after the pupil diameters for obtaining user Pupil diameters compare, and judge whether the difference between the pupil diameters of user and default pupil diameters is greater than default error threshold Value, to determine whether user is in asthenopia state according to judging result, so that in the next steps, mobile terminal can root It is adjusted according to screen intensity of the judging result to mobile terminal.

Wherein, the default pupil diameters be according in current reading parameters current screen parameter and current environment parameter it is true Fixed.

Specifically, mobile terminal can first obtain default pupil diameters, then the pupil diameters of user and default pupil are joined Number compares, and the difference between the pupil diameters of user and default pupil diameters, and the difference that will be calculated is calculated It is compared with pre-set default error threshold, judges whether the difference is greater than default error threshold.

If the difference between the pupil diameters of user and default pupil diameters, it is greater than default error threshold, then illustrates to use The pupil diameters at family change greatly, and that is to say that the pupil diameter of user varies widely, then it is tired can to determine that user is in eye Labor state.

But if difference between the pupil diameters of user and default pupil diameters, no more than default error threshold, then Illustrate that the pupil diameters of user change in error range, the pupil diameter size variation of user is little, can determine user simultaneously It is not in asthenopia state.

It should be noted that if user in the process of reading, the brightness of current environment and/or the screen of mobile terminal are bright When degree changes, the pupil diameter size of user can also change.Therefore, mobile terminal first can read ginseng according to current Current screen parameter and current environment parameter in number, judge mobile terminal screen intensity and current environment brightness whether It changes, and chooses different default pupil diameters according to the judgment result.

For example, when the brightness of the screen intensity of mobile terminal and current environment does not change, then mobile terminal Default pupil diameters can be chosen from multiple pupil diameters of the user obtained；But the if screen of mobile terminal Any one parameter in brightness and the brightness of current environment changes, then user can be started to pupil ginseng when reading Number is as default pupil diameters, alternatively, the pupil diameters of user are as default pupil ginseng when the last time is adjusted screen intensity Number.

Step 103, if more than then the screen intensity of mobile terminal is adjusted.

After multilevel iudge, if the difference between the pupil diameters of user and default pupil diameters is greater than default miss Poor threshold value then illustrates that the pupil diameter of user changes, and user is in asthenopia state, then can be actively to mobile terminal Screen intensity is adjusted, and slows down the asthenopia of user.

Specifically, when the difference between the pupil diameters and default pupil diameters for determining user is greater than default error threshold When, mobile terminal can join the current screen in current reading parameters according to the current environment parameter in current reading parameters Number is adjusted, and that is to say, the screen intensity of mobile terminal is adjusted in the ambient brightness according to locating for mobile terminal.

Wherein, mobile terminal can be adjusted screen intensity with corresponding relationship according to the pre-stored data, can also basis The history parameters of mobile terminal records, are adjusted screen intensity, and it is not limited in the embodiment of the present invention.

In conclusion screen luminance adjustment method provided in an embodiment of the present invention, the pupil by obtaining active user is joined Number, and judge the difference between the pupil diameters of user and default pupil diameters, if it is greater than default error threshold.If user's Difference between pupil diameters and default pupil diameters is greater than default error threshold, then adjusts to the screen intensity of mobile terminal Section.Judged by mobile terminal according to the pupil diameters for obtaining active user, determine whether user is in asthenopia state, When user is in asthenopia state, actively screen intensity is adjusted, to alleviate user's asthenopia, is read not interrupting user It in the case where reading, can effectively slow down the asthenopia of user, improve the viscosity that user uses mobile terminal to be read, improve Adjust the flexibility of screen intensity.

Referring to Fig. 2, a kind of step flow chart of screen luminance adjustment method of the embodiment of the present invention is shown, it specifically can be with Include the following steps:

Step 201, judge whether mobile terminal enters reading model.

In order to alleviate the asthenopia occurred in user's reading process, mobile terminal needs to be in asthenopia state in user When, screen intensity is adjusted, actively to alleviate the asthenopia of user.Therefore, mobile terminal is mobile whole before adjusting screen intensity End needs to judge whether to enter reading model, so that it is determined that whether user is being read by mobile terminal.

Specifically, mobile terminal can first determine application program corresponding to current interface, judge that can user by this Application program is read, and when determining that user can be read by the application program, then can be judged again mobile whole Whether the interface for holding current presentation is interface that user is read.

If the interface of mobile terminal current presentation is the interface that user is read, it can determine user currently just It is reading, mobile terminal comes into reading model.But if the interface of mobile terminal current presentation is not that user reads When interface, then it can determine mobile terminal and not enter reading model.

It should be noted that when mobile terminal and when not entering reading model, mobile terminal can with real-time judge whether into Enter reading model.For example, the operation that mobile terminal can be triggered according to user, determines the application program that mobile terminal is opened, with And the interface that application program is shown can then be determined when the interface for determining that mobile terminal is shown is the interface that user reads Mobile terminal enters reading model.

Step 202, if mobile terminal enters reading model, reference read parameter is obtained.

After determining that mobile terminal enters reading model, the available reference read parameter of mobile terminal, so as to subsequent In step, mobile terminal can be judged according to the reference read parameter, determine whether user is in asthenopia state.

Wherein, which may include being somebody's turn to do with reference to screen parameter, reference environment parameter and with reference to pupil diameters It can be the oculopupillary diameter of people with reference to pupil diameters, can be parameter corresponding to screen intensity with reference to screen parameter, The reference environment parameter can be parameter corresponding to ambient brightness, the embodiment of the present invention to reference read parameter without limitation.

Optionally, if mobile terminal enters reading model, available initial reading parameters, and by the initial reading parameters As reference read parameter.Specifically, after determining that mobile terminal enters reading model, mobile terminal can be read according to entering Corresponding screen intensity, ambient brightness and the pupil diameter of user size at the time of mode, determine initial screen parameter, Initial environment parameter and initial pupil parameter, to obtain by initial screen parameter, initial environment parameter and initial pupil parameter The initial reading parameters of composition, finally using initial reading parameters as reference read parameter.

For example, mobile terminal can be by the parameter corresponding to screen intensity at the time of mobile terminal enters reading model It is determined as initial screen parameter, and parameter corresponding to ambient brightness is determined as initial environment parameter, then pass through mobile terminal Front camera obtain the eyes image of user at this time, to obtain the pupil diameter size of user, then by the pupil diameter Parameter value corresponding to size is as initial pupil parameter.

Step 203, after the second preset duration, current screen parameter and current environment parameter are obtained.

Wherein, which can be set with the empirical value of human eye fatigue, can also be according to constantly acquiring Data are updated, the embodiment of the present invention to the second preset duration without limitation.

Mobile terminal after obtaining reference read parameter, can be obtained after the second preset duration current screen parameter and Current environment parameter, so that the pupil diameters of the active user obtained with subsequent step form one group of current reading parameters.

But in the process of reading due to user, the pupil size of human eye can with external environment, screen intensity and The emotional change of user and change.Therefore, in order to guarantee active user pupil diameters accuracy, mobile terminal can obtain first Current screen parameter and current environment parameter are taken, whether the reading environment where determining user changes, thus according to judgement As a result different operations is executed.

Moreover, the accuracy in order to guarantee current screen parameter and current environment parameter, mobile terminal can first acquire sample This screen parameter and sample environment parameter, and where judging user according to the sample screen parameter of acquisition and sample environment parameter Whether reading environment changes in a short time.

Optionally, the available sample screen parameter of mobile terminal and sample environment parameter, and judgement sample screen parameter Whether difference is greater than screen parameter error threshold, and/or, whether judgement sample environmental parameter difference is greater than environmental parametric deviation threshold Value.

Wherein, which obtained according to sample screen parameter, which is root It is obtained according to sample environment parameter.For example, mobile terminal can according to this obtain sample screen parameter with obtained and remembered At least one sample screen parameter of record is calculated, and the difference between two sample screen parameters is obtained, to obtain this Difference between the sample screen parameter of acquisition and the sample screen parameter for each having obtained and having recorded, and it is poor from least one The maximum difference of Selecting All Parameters value is as sample screen parameter difference in value.

Correspondingly, the acquisition modes of sample environment parameter difference, the acquisition modes class with above-mentioned sample screen parameter difference Seemingly, details are not described herein.

Specifically, mobile terminal can be obtained first and record sample screen parameter and sample environment parameter, and according to acquisition Sample screen parameter and sample environment parameter calculated, obtain sample screen parameter difference, and/or, sample environment parameter Difference, and by sample screen parameter difference, and/or, sample environment parameter difference respectively with corresponding screen parameter error threshold, And/or environmental parametric deviation threshold value is compared, whether judgement sample screen parameter difference is greater than screen parameter error threshold, And/or whether judgement sample environmental parameter difference is greater than environmental parametric deviation threshold value.

If the sample screen parameter difference is not more than screen parameter error threshold, and/or, sample environment parameter difference is not Greater than environmental parametric deviation threshold value, then illustrates that reading environment locating for user does not change, then can execute step 204, So as to the sample screen parameter and sample that will be obtained in the sample pupil diameters of the user obtained in step 204 and this step 203 Environmental parameter is recorded as one group of sample reading parameters.

But if sample screen parameter difference is greater than screen parameter error threshold, and/or, if sample environment parameter difference Greater than environmental parametric deviation threshold value, mobile terminal can delete sample screen parameter and sample environment parameter, and pre- by first If after duration, obtaining sample screen parameter and sample environment parameter again.

Wherein, which can be configured according to the emotional change duration of user, can also use other Mode is configured, and it is not limited in the embodiment of the present invention.

Specifically, if the sample screen parameter difference is greater than screen parameter error threshold, and/or, sample environment parameter Difference is greater than environmental parametric deviation threshold value, then illustrates the sample screen parameter and sample environment parameter of this acquisition, and adopt before Sample screen parameter and sample environment the parameter difference of collection are larger, and reading environment locating for user has occurred and that variation, then moves Terminal can empty the sample pupil ginseng of acquired sample screen parameter and sample environment parameter and corresponding user Number, and collecting sample screen parameter and the sample environment parameter again after the first preset duration.

It should be noted that then may be used when mobile terminal is to obtain sample screen parameter and sample environment parameter for the first time Not to be compared to sample screen parameter and sample environment parameter, but directly record sample screen parameter and sample environment ginseng Number, and execute step 204.

Step 204, the pupil diameters of active user are obtained.

Mobile terminal is after obtaining a sample screen parameter and sample environment parameter, if it is determined that the reading where user Environment does not change, then can execute the sample pupil diameters that this step 204 obtains user, and by step 203 and step The sample pupil diameters of 204 this sample screen parameter, sample environment parameter and the users that obtain respectively are read as one group of sample Parameter is read, then chooses current reading parameters from the multiple groups sample reading parameters of acquisition, so that it is determined that the pupil of active user is joined Number.

In the process of reading due to user, even if external environment and screen intensity do not change, it will not lead to user's Pupil diameter size changes, but when user emotion changes, the pupil diameter size of user can also change.

Therefore, mobile terminal needs sample of the pupil diameters that will be acquired as user after collecting pupil diameters Pupil diameters, and judge whether the sample pupil diameters of the user of this acquisition vary widely, and lead to the current of acquisition The pupil diameters inaccuracy of user, then step 204 may include step 204a, step 204b and step 204c:

Step 204a obtains the sample pupil diameters of user.

The sample of the available user corresponding with sample screen parameter in step 203 and sample environment parameter of mobile terminal This pupil diameters, thus one group of sample reading parameters of composition, so that mobile terminal can be selected in enough sample datas It takes, obtains the pupil diameters of the active user in current reading parameters.

Optionally, if sample screen parameter difference is not more than screen parameter error threshold, and/or, sample environment parameter difference Value is not more than environmental parametric deviation threshold value, the sample pupil diameters of the available user of mobile terminal.

Specifically, the eyes image of user can be obtained by the front camera of mobile terminal, and uses image recognition Technology identifies the eyeball image in eyes image, obtains the eyeball image of user, further according to bright pupil hole and dark pupil skill Art is analyzed, and is extracted and is obtained the diameter of the pupil of user, finally using the diameter of the pupil as the sample of user Pupil diameters simultaneously record, obtain include the sample pupil diameters of sample screen parameter, sample environment parameter and user sample Reading parameters.

Mobile terminal is after the sample pupil diameters for obtaining user, it is also necessary to by the sample pupil of this user obtained Parameter is compared with the sample pupil diameters of the user obtained, determine user whether in the short time by emotional change It influences, the pupil diameter size of user is caused to vary widely in a short time.

Optionally, mobile terminal may determine that whether sample pupil diameters difference is greater than default error threshold.Wherein, the sample This pupil diameters difference is to be obtained according to the sample pupil diameters of user.Moreover, the calculation of the sample pupil diameters difference, Similar with the acquisition modes of sample screen parameter difference in step 203, details are not described herein.

Specifically, mobile terminal can be calculated first according to the sample pupil diameters of the user of acquisition, obtain sample pupil Hole parameter difference, and judge whether the sample pupil diameters difference is greater than default error threshold.When sample pupil diameters difference not When greater than default error threshold, illustrate that user does not occur emotional change and the diameter of pupil is caused to change；But It is, if sample pupil diameters difference is greater than default error threshold, to illustrate that the mood of user changes in the short time, this The sample reading parameters of acquisition can not really reflect the state of user.

Therefore, when sample pupil diameters difference is not more than default error threshold, what mobile terminal can obtain this Sample pupil diameters of the pupil diameters as user, and by the sample pupil diameters of user, sample screen parameter and sample environment Parameter is as sample reading parameters, then executes step 204b.

But if sample pupil diameters difference is greater than default error threshold, mobile terminal can delete the sample of user Pupil diameters, and after the first preset duration, the sample pupil diameters of user are obtained again.It that is to say, when sample pupil is joined When number difference is greater than default error threshold, illustrate that the pupil diameter of user in a short time varies widely, this record The sample pupil diameters of user differ larger with the sample pupil diameters of the user recorded before, the use that cannot be acquired according to this Pupil diameters of the sample pupil diameters at family as active user need to carry out the sample pupil diameters of acquired user It deletes, and sample screen parameter corresponding with the sample pupil diameters of each user and sample environment parameter is deleted.

Further, after the first preset duration, mobile terminal can obtain sample screen parameter and sample again Environmental parameter can execute again if sample screen parameter and sample environment parameter meet the corresponding conditions in step 203 Step 204a obtains the sample pupil diameters of user again.

Step 204b, judges whether the number of the sample pupil diameters of user is less than sample threshold.

Mobile terminal can determine the sample pupil diameters of user after the sample pupil diameters for obtaining at least one user Number, and the number is compared with pre-set sample threshold, so that it is determined that whether mobile terminal obtains enough The sample pupil diameters and sample reading parameters of the user of number, so that mobile terminal can select in enough sample datas Take the sample pupil diameters at family.

Optionally, if sample pupil diameters difference is not more than default error threshold, mobile terminal may determine that the sample of user Whether the number of this pupil diameters is less than sample threshold.When the number of the sample pupil diameters of user is not less than sample threshold, Then illustrate the sample pupil diameters for having obtained the user of enough numbers, step 204c can be executed, from the sample of multiple users The pupil diameters of active user are chosen in this pupil diameters；But if the number of the sample pupil diameters of user is less than sample Threshold value, then there is still a need for the sample pupil diameters for continuing acquisition user for explanation, until the number of the sample pupil diameters of user is not Less than sample threshold.

It should be noted that if the number of the sample pupil diameters of user is less than sample threshold, by the first preset duration Afterwards, the sample pupil diameters of user are obtained again, until the number of the sample pupil diameters of user is not less than sample threshold.Namely It is that, if the number of the sample pupil diameters of user is not more than sample threshold, mobile terminal can execute step 203 again, To obtain sample screen parameter and sample environment parameter again, to acquire the sample pupil of user under identical reading environment Hole parameter improves the accuracy of the pupil diameters of determining active user.

Step 204c chooses intermediate value sample pupil ginseng if the number of the sample pupil diameters of user is not less than sample threshold Pupil diameters of the number as user.

Wherein, which is at least one sample pupil diameters of user, and parameter value is median Sample pupil diameters.

If the number of the sample pupil diameters of user is not less than sample threshold, the available multiple users of mobile terminal The corresponding parameter value of sample pupil diameters, and sentenced according to the parameter value size of the sample pupil diameters of each user It is disconnected, choose pupil diameters of the intermediate value sample pupil diameters as user, and by one group of sample belonging to intermediate value sample pupil diameters Reading parameters are as current reading parameters, so that obtaining includes the pupil diameters of user, current screen parameter and current environment ginseng Several current reading parameters.

Specifically, mobile whole when mobile terminal determines the number of the sample pupil diameters of user not less than sample threshold The parameter value of the sample pupil diameters of each user in the sample pupil diameters of available multiple users is held, and to each user The parameter values of sample pupil diameters be compared, the sample pupil diameters for the user that parameter value size is median are determined as Intermediate value sample pupil diameters finally using intermediate value sample pupil diameters as the pupil diameters of user, and intermediate value sample pupil are joined One group of sample reading parameters belonging to number are as current reading parameters.

Wherein, the value range of the sample threshold can be 2 to 4, it is, of course, also possible to take other numerical value as sample threshold Value, it is not limited in the embodiment of the present invention.

It should be noted that the mode of reference read parameter is obtained in step 202, it can be with this step 203 to step 204 The middle process for obtaining current reading parameters is similar, that is to say, by obtaining multiple sample reading parameters, reads and joins from multiple samples It is selected in number, obtains reference read parameter.

In addition, mobile terminal can not also execute step 203, but step 204 is executed after executing step 202, namely It is that after obtaining reference read parameter, current screen parameter and current environment parameter are no longer obtained after the second preset duration, But after the second preset duration, the pupil diameters of active user are obtained.

Step 205, judge whether current screen parameter difference is greater than screen parameter error threshold, and/or, front ring is worked as in judgement Whether border parameter difference is greater than environmental parametric deviation threshold value.

Wherein, which obtained according to current screen parameter, which is root It is obtained according to current environment parameter, the acquisition modes of the current screen parameter difference and current environment parameter difference, and in step 203 The mode for obtaining sample screen parameter difference is similar, and details are not described herein.

For user during being read by mobile terminal, mobile terminal can obtain different work as in different moments The pupil diameters of forth screen parameter, current environment parameter and active user, and by the current screen parameter obtained in synchronization, The pupil diameters of current environment parameter and active user are as one group of current reading parameters, then will acquire every group currently reads ginseng Number is recorded as history reading parameters, in the next steps, to be tied according to each group history reading parameters of record The current reading parameters for closing this acquisition of mobile terminal, judge whether user is in asthenopia state.

In user's reading process, reading environment locating for user may change, such as screen intensity enhancing, or Ambient brightness enhancing etc., then the pupil diameter size of user can also change.Therefore, in the pupil diameter size for judging user Before whether changing, need to judge whether reading environment locating for user changes, and according to judging result using not Same mode judges whether user is in asthenopia state.

Specifically, after the current reading parameters of acquisition for mobile terminal, the current screen in current reading parameters can be joined Number, and/or, current screen parameter and current environment parameter in current environment parameter, with each history reading parameters of record Be compared, obtain current screen parameter difference and/or current environment parameter difference, and by current screen parameter difference and/or Current environment parameter difference is compared with corresponding screen parameter error threshold and environmental parametric deviation threshold value, and judgement is current Whether screen parameter difference is greater than screen parameter error threshold, and/or, judge whether current environment parameter difference is greater than environment ginseng Number error threshold.

Moreover, because mobile terminal can recorde multiple groups history reading parameters, then mobile terminal is being compared judgement In the process, at the time of can be according to each history reading parameters be recorded, first choose record moment forward history reading parameters with Current screen parameter in current reading parameters, and/or, current environment parameter is compared, and obtains current screen parameter difference And/or current environment parameter difference, if the current screen parameter difference and/or current environment parameter difference are joined no more than screen Number error threshold and/or environmental parametric deviation threshold value, then can determine that reading environment locating for user does not change, can Judge whether the pupil diameter size of user changes to execute step 206.

But if the current screen parameter difference and/or current environment parameter difference are greater than screen parameter error threshold, And/or environmental parametric deviation threshold value, mobile terminal can work as according at the time of recording each history reading parameters with this acquisition Difference between at the time of preceding reading parameters chooses corresponding history reading parameters according to the sequence of difference from big to small, thus New current screen parameter difference and/or current environment parameter difference is calculated, judges the new current screen parameter difference, And/or whether current environment parameter difference is greater than screen parameter error threshold and/or environmental parametric deviation threshold value.

If screen parameter error threshold is still greater than in new current screen parameter difference and/or current environment parameter difference Value and/or environmental parametric deviation threshold value, then mobile terminal can continue to choose history reading parameters and current reading parameters carry out Compare, until current screen parameter difference is obtained every time after each history reading parameters are compared with current reading parameters, And/or current environment parameter difference is both greater than screen parameter error threshold and/or environmental parametric deviation threshold value, it may be considered that Reading environment locating for user changes, and can execute step 207 and judge whether the pupil diameter size of user changes.

Moreover, according to current screen parameter, and/or, current environment parameter is compared with each history reading parameters During, if current screen parameter, and/or, it is current between current environment parameter and any one group of history reading parameters Screen parameter difference and/or current environment parameter difference are not more than screen parameter error threshold and/or environmental parametric deviation threshold Value, it may be considered that reading environment locating for user does not change.

Step 206, if current screen parameter difference is not more than screen parameter error threshold, and/or, if current environment parameter Difference is not more than environmental parametric deviation threshold value, judges the difference between the pupil diameters of user and default pupil diameters, if big In default error threshold.

If it is determined that current screen parameter difference is not more than screen parameter error threshold, and/or, determine current environment parameter Difference is not more than environmental parametric deviation threshold value, then can determine that reading environment locating for user does not change, the pupil of user Pore diameter size will not generate variation because of reading environment.Therefore, mobile terminal can be according to the active user's of acquisition Pupil diameters, determine whether user is in asthenopia state.

Specifically, current screen parameter is being determined, and/or, between current environment parameter and a certain group of history reading parameters Current screen parameter difference and/or current environment parameter difference, no more than screen parameter error threshold and/or, environmental parameter After error threshold, the history pupil diameters of user in available this group of history reading parameters join the history pupil of the user Number compares the pupil diameters and default pupil diameters of user as default pupil diameters, obtains the pupil diameters of user and pre- If the difference between pupil diameters, judge whether the difference is greater than default error threshold.

If the difference is greater than default error threshold, mobile terminal if, can execute step 209 and adjust to screen intensity Section；But if the difference is not more than default error threshold, illustrates user and do not enter asthenopia state, step can be executed 211, obtain current reading parameters again after the second preset duration.

Step 207, if current screen parameter difference is greater than screen parameter error threshold, and/or, if current environment parameter difference Value is greater than environmental parametric deviation threshold value, judges whether current screen parameter is greater than with reference to screen parameter, and/or, front ring is worked as in judgement Whether border parameter is less than reference environment parameter.

If it is determined that current screen parameter difference is greater than screen parameter error threshold, and/or, determine current environment parameter difference Value is greater than environmental parametric deviation threshold value, then can determine that reading environment locating for user changes, the pupil diameter of user is big It is small may as the variation of reading environment and generate variation.

Therefore, mobile terminal can first obtain reference read parameter, and determine mobile terminal according to reference read parameter Whether screen intensity enhances, and/or, determine whether the brightness of current environment weakens, if the screen intensity of mobile terminal enhances, And/or the brightness deterioration of current environment, the pupil diameter size of user can become smaller under normal circumstances, then in the next steps, Mobile terminal can determine whether user enters asthenopia state according to the pupil diameters of reference pupil diameters and user.

But if the screen intensity of mobile terminal weakens, and/or, the brightness of current environment enhances, then the pupil of user Diameter can become larger under normal circumstances, accurately can not determine whether user enters asthenopia state, then can pass through second After preset duration, the pupil diameters of user are obtained again.

Step 208, if current screen parameter, which is greater than, refers to screen parameter, and/or, if current environment parameter is less than reference rings Border parameter, judges whether the pupil diameters of user are greater than with reference to pupil diameters and default error threshold and value.

If it is determined that current screen parameter, which is greater than, refers to screen parameter, and/or, current environment parameter is joined less than reference environment Number, then under normal circumstances, the pupil size of user can become smaller, and mobile terminal can will then be used as default pupil with reference to pupil diameters Hole parameter, and judge according to the pupil diameters of active user and with reference to pupil diameters, determine whether user enters asthenopia State.

Specifically, mobile terminal can first be calculated with reference between pupil diameters and default error threshold and value, then The pupil diameters of active user are compared with this and value, judges whether the pupil diameters of active user are greater than and joins with reference to pupil Several between default error threshold and value.

If the pupil diameters of active user are greater than with reference between pupil diameters and default error threshold and value, illustrate User's pupil diameter becomes larger, and user enters asthenopia state, then can execute step 209, be adjusted to screen intensity.

But if the pupil diameters of active user be not more than with reference between pupil diameters and default error threshold and Value, then illustrate user and do not enter asthenopia state, then can execute step 211, after the second preset duration, Ke Yizai It is secondary to obtain current reading parameters.

Step 209, if more than then the screen intensity of mobile terminal is adjusted.

If mobile terminal determines that user enters asthenopia state, mobile terminal can be gone through with multiple groups according to the pre-stored data History parameter searches target histories parameter corresponding with current environment parameter, to go through according to the target in target histories parameter History screen parameter is updated current screen parameter, and then according to updated current screen parameter, carries out to screen intensity It adjusts.

Optionally, mobile terminal can according to the corresponding history environment parameter of every group of history parameters, search obtain with The corresponding target histories parameter of current environment parameter, judges whether target histories fatigue duration is greater than current tired duration, if Target histories fatigue duration is greater than current tired duration, then can be bright according to screen of the target histories screen parameter to mobile terminal Degree is adjusted.

Wherein, which may include that target histories screen parameter, target histories environmental parameter and target are gone through History fatigue duration, the current tired duration be according at the time of the pupil diameters for obtaining user and obtain with reference to pupil diameters when Quarter obtains.

Specifically, mobile terminal, can be first according to the current reading parameters of acquisition after determining that user enters asthenopia state Time point, and obtain time point of reference read parameter and calculated, obtain current tired duration, that is to say that user enters eye The time span of fatigue state.

Meanwhile mobile terminal can also be searched at least one set of history parameters according to current environment parameter and work as front ring The consistent history environment parameter of border parameter, and target histories parameter is determined according to the history environment parameter, to obtain target History fatigue duration.

Mobile terminal is after obtaining target histories fatigue duration, when can be by the target histories fatigue duration and current fatigue Length compares, and judges whether target histories fatigue duration is greater than current tired duration.If target histories fatigue duration is greater than Current fatigue duration, then illustrate under user's screen intensity corresponding to the target histories screen parameter in target histories parameter, Having read the longer time just enters asthenopia state, then current screen parameter can be updated to target histories screen parameter, New current screen parameter is obtained, and the screen intensity of mobile terminal is adjusted according to new current screen parameter.

But if history fatigue duration needs to judge reading locating for user again no more than current tired duration Whether environment changes, and that is to say and judges whether mobile terminal performs step 206 and step 207.

If mobile terminal execution step 206 and 207, illustrates that reading environment locating for user does not change, And under user's screen intensity corresponding to current screen parameter, the longer time has been read just into asthenopia state, then has been moved Terminal can be according to current tired duration and current screen parameter, to the target histories fatigue duration and mesh in target histories parameter Mark History screen parameter is updated, and when so that screen intensity being adjusted again, mobile terminal can be according to updated Screen intensity is adjusted in history parameters.

It should be noted that if mobile terminal does not find target histories ginseng corresponding with current environment parameter Number can then be deposited using current screen parameter, current environment parameter and current tired duration as one group of new history parameters Storage.

Step 210, according to current reading parameters, reference read parameter is updated.

Wherein, which may include the pupil diameters of user, current screen parameter and current environment parameter.

Mobile terminal illustrates that user starts to read in new reading environment, then after adjusting to screen intensity The current reading parameters that can be obtained according to this, the reference read parameter obtained to step 202 is updated, so as to subsequent During adjusting, mobile terminal can determine whether user enters according to the current reading parameters that this is obtained as reference Asthenopia state.

Therefore, mobile terminal can replace with the reference pupil diameters in reference read parameter in current reading parameters Current pupil diameters；Current screen parameter will be replaced with reference to screen parameter；Reference environment parameter is replaced with into current environment ginseng Number.

Moreover, mobile terminal can also empty the history reading parameters of record, and current reading parameters are reacquired, to make For history reading parameters, the problem of occupying excessive memory space, causing memory space redundancy is avoided.

Step 211, if being less than, after the second preset duration, the pupil diameters of active user are obtained again.

If the difference between the pupil diameters of user and default pupil diameters is not more than default error threshold, illustrate to use Family does not simultaneously enter asthenopia state, and mobile terminal is without being adjusted screen intensity, but after the second preset duration, The pupil diameters for obtaining user again, judge whether user enters asthenopia state again.

Further, it by searching for history parameters, and according to the target histories fatigue duration in target histories parameter, determines Screen intensity corresponding to target histories screen parameter in target histories parameter, if better than corresponding to current screen parameter Screen intensity, so that screen intensity be adjusted according to target histories screen parameter.By comparing target histories fatigue duration With current tired duration, can accurately determine user under which kind of screen intensity into the time of asthenopia state later, mention The high accuracy for adjusting screen intensity.

Further, by obtaining multiple groups sample reading parameters, and it is not less than sample threshold in the number of sample reading parameters When value, from multiple sample reading parameters, sample reading parameters belonging to sample pupil diameters are chosen as current reading parameters. By choosing current reading parameters from multiple groups sample reading parameters, the accuracy of current reading parameters can be improved, so that choosing The current reading parameters taken are more nearly the time of day of user.

Further, whether screen parameter error threshold is greater than by judgement sample screen parameter difference, and/or, judgement Whether sample environment parameter difference is greater than environmental parametric deviation threshold value, and reading ring locating for user can be determined according to judging result Whether border changes, and avoids leading to the changed feelings of sample pupil diameters of user since reading environment changes Condition improves the accuracy for obtaining sample reading parameters.

Further, whether default error threshold is greater than by judgement sample pupil diameters difference, can be tied according to judgement Fruit, determines whether user causes the sample pupil diameters of user to change due to emotional change, avoids due to user emotion The case where changing and the sample pupil diameters of user is caused to change improves and obtains the accurate of sample reading parameters Property.

Further, the reading environment as locating for user changes, alternatively, the mood due to user changes When, when sample pupil diameters being caused to change, recorded sample reading parameters can be deleted, and collecting sample is read again Parameter is read, the accuracy for obtaining sample reading parameters is improved.

Further, whether screen parameter error threshold is greater than by current screen parameter difference, and/or, judgement is current Whether environmental parameter difference is greater than environmental parametric deviation threshold value, can determine whether the reading environment that user is currently located becomes Change, and determine whether the pupil diameters of active user change in different ways according to judging result, improves determination Whether user enters the flexibility of asthenopia state.

Further, when the reading environment that user is currently located changes, by the current reading parameters of this acquisition It is compared with the reference read parameter acquired before, determines whether user enters asthenopia state, improving confirmation user is The no flexibility into asthenopia state.

Further, after mobile terminal enters reading model, available reference read parameter that is to say determining user Corresponding parameters when starting to read, whether to determine user according to the reference read parameter in the next steps Into asthenopia state, the flexibility whether confirmation user enters asthenopia state is improved.
