The maximum of eyes is characterized in recognizing the ability of details, often be indicated with vision addressability, and referred to as eyesight.Expression The standard of eyesight is subtended angle of the minimum character that can recognize of human eye to human eye, and the eye eyesight of normal person is 1.0 or more, usual institute The eyesight said refer to eyes minimum can point eyesight, rather than minimum visible eyesight, so visual chart reflection examinee watches mesh attentively 2 points of minimum visions separated are marked, i.e. minimum can divide eyesight, can represent examinee's optimum visual function.
Eyesight is generally detected by visual chart.
Visual chart is the chart for measuring eyesight, is designed according to the principle of vision.So-called vision is exactly by the external world 2 points of light sent out are formed by angle through intraocular node.Under normal circumstances, human eye can tell the minimum range of point-to-point transmission It is minimum vision, i.e. one point of vision to be formed by vision.Visual chart is exactly to be designed as unit of one point of vision.
The myopic degree of eyesight is tested, international standard visual chart is generally used, as shown in Figure 1, being international standard visual chart Schematic diagram, one column of figure of the left side is eyesight grade, and the figure " E " on the right be the figure that identifies of needs when giving a test of one's eyesight.Detection When eyesight, measured needs to stand at the position of international standard visual chart 5m, and medical staff indicates international standard visual chart On figure " E ", measured answers the opening direction of figure " E ", and the result that medical staff answers according to tester judges to detect The eyesight rank of person.
As electronic product is increasing in life, electronic product is faced for a long time, and myopia degree is gradually deepened, such as Fruit electronic product can detect roughly human eyesight, and people could be aware that the eyesight variation of oneself when using electronic product Trend can then make people improve use habit, help to protect eyesight.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
As shown in Fig. 2, a kind of method to give a test of one's eyesight provided in an embodiment of the present invention, specifically includes following steps：
S200, terminal determine currently detected according to the mapping relations of eyesight grade, measuring distance and test pattern Measuring distance and the current corresponding test pattern of eyesight grade, wherein measuring distance are the display screen of eyes of user and terminal The distance between；
S201, the terminal are shown according to determining test pattern；
S202, the terminal determine eyesight testing result according to the user behavior recognized and the test pattern of display.
Terminal obtains the distance between the display screen of eyes of user and terminal by camera and sensor, this distance is Measuring distance, terminal determine currently detected test according to the mapping relations of eyesight grade, measuring distance and test pattern Distance and the current corresponding test pattern of eyesight grade.Determining test pattern is shown in terminal, and according to the use recognized The test pattern of family behavior and display determines eyesight testing result.Due to storing eyesight grade, measuring distance and inspection in terminal The mapping relations of mapping shape, so not needing standard visual acuity chart when giving a test of one's eyesight, also not needing the requirement of fixed range can examine The eyesight for surveying user, can give a test of one's eyesight thereby using family, contributes to sight protectio at any time.
Terminal can be mobile phone, tablet computer in the embodiment of the present invention, can also be the device of special detection eyesight.
In force, first have to make the mapping table of the mapping relations of eyesight grade, measuring distance and test pattern.Depending on The mapping table of power grade, measuring distance and test pattern is obtained by repeatedly testing, and ensures the accuracy of data.
It should be noted that measuring distance is the distance between the display screen of eyes of user and terminal.
The same eyesight grade, according to different measuring distances, corresponding different size of test pattern.Same eyesight etc. Grade, the same measuring distance, corresponding test pattern can be one, can also be that size is identical, different multiple in direction.
As shown in figure 3, being the same eyesight grade of the embodiment of the present invention, the same measuring distance, corresponding detection figure The schematic diagram of shape.When eyesight grade is 0.1, each measuring distance corresponds to a test pattern, and each measuring distance is corresponding Each test pattern is of different sizes, and measuring distance can be set as between 20cm to 60cm according to actual needs.It is same to regard The size of power grade, different measuring distances, test pattern also differs, since the range difference of adjacent measuring distance is smaller, So in the case of eyesight grade is identical, the size difference of the corresponding test pattern of neighbor distance is not very big, but is actually regarded Power grade is identical, and the size of the corresponding test pattern of neighbor distance is different.Measuring distance can be increased with 0.2cm, also may be used It, in force can basis to select 0.1cm or even smaller, the embodiment of the present invention not to limit the range difference of neighbor distance Actual needs determines.
As shown in figure 4, being the same eyesight grade of the embodiment of the present invention, the same measuring distance, corresponding multiple detection figures The schematic diagram of shape.Here multiple test patterns, actually size is identical, the different multiple test patterns in direction.For example it regards When power grade is 0.1, measuring distance 20cm, corresponding four same sizes, the test pattern of different directions；Eyesight grade is When 0.1, measuring distance 20.2cm, equally corresponding four same sizes, the test pattern of different directions.Eyesight grade is 0.1 When, measuring distance is 20cm corresponding test pattern sizes when less than eyesight grade being 0.1, and measuring distance is that 20.2cm is corresponding The size of test pattern.Same eyesight grade, since the range difference of adjacent measuring distance is smaller, so eyesight grade is identical In the case of, the size difference of the corresponding test pattern of neighbor distance is not very big, figure 4, it is seen that eyesight grade is 0.1, measuring distance is the corresponding feature sizes of 20cm and eyesight grade is 0.1, and measuring distance is that the corresponding figures of 20.4cm are big It is small, it can significantly find out that eyesight grade is 0.1, it less than eyesight grade is 0.1 that measuring distance, which is the corresponding feature sizes of 20cm, Measuring distance is the corresponding feature sizes of 20.4cm.
According to actual needs, measuring distance may be set between 20cm to 60cm, if range sensor identification away from From not between 20cm to 60cm, then in the display interface bullet frame tip distance of terminal, in pre-determined distance range, (20cm is not arrived In 60cm).
After the mapping table of eyesight grade, measuring distance and test pattern establishes, in the terminal by the storage of this mapping table.
The embodiment of the present invention is by taking mobile phone as an example, and user after starting eyesight detection function, by front camera known by mobile phone It is clipped to facial angle, the distance between face and display screen are identified by sensor, according to facial angle and face and display screen The distance between calculate the distance between human eye and display screen.Mobile phone according between facial angle and face and display screen away from It is measuring distance from the distance between calculated human eye and display screen.
Every time carry out eyesight detection when, will determine the distance between human eye and terminal display screen because every time detection away from From being possible to all different.
After terminal determination meets trigger condition, according to the mapping relations of eyesight grade, measuring distance and test pattern, really Fixed currently detected measuring distance and the current corresponding test pattern of eyesight grade.
Some or all of here trigger condition includes five kinds, meet in this five kinds of trigger conditions, terminal can be true Fixed currently detected measuring distance and the current corresponding test pattern of eyesight grade.Individually below to this five kinds of trigger conditions It illustrates.
The first, user, which triggers, carries out eyesight detection.
For example, the software installation to give a test of one's eyesight, on mobile phone, user clicks software, eyesight detection is carried out, at this point, terminal is true Fixed currently detected measuring distance and the current corresponding test pattern of eyesight grade, wherein current eyesight grade can be What user manually selected, can also be the visual standards of the standard class stored in terminal, can also be to be stored according in terminal The visual standards that detect of user's last time.
Second, determine eyesight border detection.
What needs to be explained here is that the embodiment of the present invention, is divided into non-eyesight border detection and eyesight boundary by eyesight detection Detection.When eyesight detects, if as shown in figure 5, mistake is identified to the corresponding test pattern of current eyesight grade, by current eyesight Grade reduces, and can reduce level-one, can also reduce two-stage, the series once reduced can be manually set, the embodiment of the present invention It is illustrated with reducing level-one.Current eyesight grade is reduced into level-one, if identified to the corresponding test pattern of a low grade wrong Accidentally, then continue eyesight grade reducing level-one, until dropping to the lowermost level of eyesight grade or to the corresponding detection figure of eyesight grade Until shape identification is correct；If identified the corresponding test pattern of a low grade for current eyesight grade correctly, by low first-class Grade is used as eyesight boundary, and eyesight border detection is carried out to low first-class grade.
If as shown in fig. 6, being identified correctly to the corresponding test pattern of current eyesight grade, current eyesight grade is carried It rises, level-one can be promoted, two-stage can also be promoted, the series once promoted can be manually set, and the embodiment of the present invention is to be promoted Level-one illustrates.Current eyesight grade is promoted into level-one, if identified to the corresponding test pattern of a high grade after promotion Correctly, then continue to promote eyesight grade, until being promoted to the highest level of eyesight grade or to the corresponding detection of eyesight grade Until figure identification mistake；If mistake is identified to the corresponding test pattern of a high grade for eyesight grade, by present level As eyesight boundary, eyesight border detection is carried out to present level.
For example, current eyesight grade is 1.0, if identifying mistake to 1.0 corresponding test pattern of eyesight grade, will regard Power grade reduces level-one, is reduced to 0.9, then be detected to eyesight grade 0.9, if schemed to the 0.9 corresponding detection of eyesight grade Shape identifies mistake, then reduces level-one again on the basis of eyesight grade 0.9, be reduced to 0.8, then be detected to eyesight grade 0.8, If identifying mistake to 0.8 corresponding test pattern of eyesight grade, level-one is reduced again on the basis of eyesight rank is 0.8, And so on, until being preferably minimized grade；If identified correctly to 0.9 corresponding test pattern of eyesight grade, will regard Power grade 0.9 carries out eyesight border detection as eyesight boundary, to eyesight boundary 0.9；If to the 0.9 corresponding inspection of eyesight grade Mapping shape identifies mistake, then eyesight grade is reduced to 0.8, if identified correctly to 0.8 corresponding test pattern of eyesight grade, By eyesight grade 0.8 as eyesight boundary, eyesight border detection is carried out to eyesight grade 0.8.
It gives one example again, for example current eyesight grade is 1.0, just to the identification of 1.0 corresponding test pattern of eyesight grade Really, then eyesight grade is promoted into level-one on the basis of eyesight grade 1.0, becomes 1.1, if corresponding to eyesight grade 1.1 Test pattern identification is correct, then eyesight grade is promoted level-one on the basis of eyesight grade 1.1 again, become 1.2, in eyesight etc. When grade is 1.2, eyesight is detected, if identified correctly to 1.2 corresponding test pattern of eyesight grade, continues to lift up and regards Power grade, until eyesight grade promotes the superlative degree to eyesight grade；If mistake is identified to eyesight grade 1.1, by eyesight Grade 1.0 carries out eyesight border detection as eyesight boundary, to eyesight grade 1.0.
It is the explanation carried out to how to determine eyesight boundary above, it is determined that after eyesight boundary, carried out to eyesight boundary Be detected as eyesight border detection, in the embodiment of the present invention, in addition to eyesight border detection, others detection is all non-eyesight boundary Detection.
Second in trigger condition, that is to say, that determine and carry out eyesight border detection, then terminal confirmly detects Distance and the current corresponding test pattern of eyesight grade.
The third, the eyesight grade that the last time carries out non-eyesight border detection carries out non-eyesight boundary before more than last The eyesight grade of detection, and the last eyesight testing result for carrying out non-eyesight border detection is correct.
For example, eyesight is detected as non-eyesight border detection, last eyesight grade is 1.0, to eyesight grade be 1.0 it is non- The testing result of eyesight border detection is correct, and the eyesight grade before the last time is less than eyesight grade 1.0, that is to say, that The eyesight grade of last time is 0.9, is identified correctly to eyesight grade 0.9, then enters the detection of eyesight grade 1.0, to eyesight etc. The testing result of grade 1.0 is correct, then eyesight grade is promoted level-one, is promoted to 1.1, eyesight grade 1.1 is current eyesight etc. Grade, then terminal determines currently detected measuring distance and the current corresponding test pattern of eyesight grade.
4th kind, the eyesight grade that the last time carries out non-eyesight border detection carries out non-eyesight boundary before less than last The eyesight grade of detection, and the last eyesight testing result for carrying out non-eyesight border detection is mistake.
For example, eyesight is detected as non-eyesight border detection, last eyesight grade is 1.0, and the eyesight grade of last time is 1.1, that is, eyesight grade of upper last time is 1.1, when carrying out non-eyesight border detection to the eyesight grade 1.1 of upper last time, detection As a result it is mistake, then eyesight grade is reduced into level-one, be reduced to 1.0, non-eyesight border detection is carried out to eyesight grade 1.0.It is right When eyesight grade 1.0 carries out non-eyesight border detection, testing result is mistake, then eyesight grade is reduced level-one again, be reduced to 0.9, by eyesight grade 0.9 as current eyesight grade, terminal determines currently detected measuring distance and current eyesight The corresponding test pattern of grade.
5th kind, completion carries out non-eyesight border detection for the first time.
This trigger condition is, when user, which triggers, carries out eyesight detection, terminal starts to carry out eyesight detection to user, than It is 1.0 as user selects eyesight grade, then terminal is according to the mapping relations of eyesight grade, measuring distance and test pattern, really Fixed currently detected measuring distance and the current corresponding test pattern of eyesight grade, test pattern are shown on the display screen Show, terminal determines eyesight testing result according to the user behavior recognized and the test pattern of display, this process is to carry out for the first time Non- eyesight border detection, after completing non-eyesight border detection for the first time, no matter eyesight testing result is correct or mistake, and terminal is all Determine currently detected measuring distance and the current corresponding test pattern of eyesight grade.
It is determined that trigger condition, terminal determine and work as according to the mapping relations of eyesight grade, measuring distance and test pattern Before the measuring distance that detects and when the corresponding test pattern of current eyesight grade, if it is determined that test pattern there are one, The then determining test pattern of the terminal display；If it is determined that test pattern have multiple, then the terminal is from determining multiple One is selected in test pattern, and shows the test pattern of selection.
For example, there are one the test patterns determined, then terminal shows determining test pattern.As shown in figure 3, eyesight grade It is 0.1, measuring distance 20cm, corresponding test pattern is " E " of opening to the right, then eyesight grade, test are shown in terminal Eyesight grade in the mapping table of distance and test pattern is 0.1, and measuring distance is the corresponding test patterns of 20cm.
Determining test pattern has multiple, the then selection one from determining multiple test patterns, and shows the inspection of selection Mapping shape.As shown in figure 4, eyesight grade is 0.1, measuring distance 20cm, there are four corresponding test patterns, is respectively open Upwards, downwards, to the left, " E " to the right, terminal are randomly choosed from four figures on a display screen for being shown in terminal.
After test pattern determines, the determining test pattern of terminal display.
Terminal determines eyesight testing result according to the test pattern shown in the behavior of identification user and terminal.
Here the behavior of user is the user behavior that terminal can identify, such as the sound of user, action.
Terminal shows test pattern on a display screen, for example test pattern is figure " E ", and user, which identifies, to be shown on screen The opening direction of figure " E ", user can say the opening direction of figure " E ", can also use gesture and point out the opening of figure " E " Rectangular, sound or action of the terminal by identification user judge that the opening direction of the figure " E " on the display screen of user's identification is It is no correct, that is, terminal determines eyesight testing result.
Terminal determines currently detected test according to the mapping relations of eyesight grade, measuring distance and test pattern Distance and the current corresponding test pattern of eyesight grade, the mapping relations of eyesight grade, measuring distance and test pattern are It pre-sets, the current measuring distance detected is that the camera of terminal recognizes the angle of face, passes through sensor The distance between face and terminal display screen are recognized, terminal is calculated according to facial angle and the distance between face and display screen Go out human eye the distance between to screen.Terminal determines test pattern, then also needs to determine current eyesight grade.
These three modes for determining eyesight grade are described in detail below there are three types of mode in the determination of eyesight grade.
The first, if terminal carry out be to detect for the first time, the eyesight grade that user select by terminal as currently Eyesight grade.
For example, user opens the software to give a test of one's eyesight on mobile phone, eyesight grade 1.0 is selected, this is detected as the first time Eyesight detects, and the eyesight grade 1.0 that terminal selects user is as current eyesight grade.
Second, if the last eyesight testing result for carrying out non-eyesight border detection be correct, and the last time regards Power grade is more than the last eyesight grade for carrying out non-eyesight border detection before, then the last time is carried out non-eyesight boundary by terminal The eyesight grade of detection is promoted, and using the eyesight grade after promotion as current eyesight grade.
When carrying out non-eyesight border detection, if last testing result is correct, eyesight grade is promoted into level-one, after Continuous detection, if detected again, the eyesight grade after promotion is then promoted level-one, detected again, directly by testing result or correct again Reach the superlative degree of eyesight grade.
Since last eyesight grade is more than the last eyesight grade for carrying out non-eyesight border detection before, then illustrate When last time is detected, last time testing result is correct, then eyesight grade promotes level-one, is detected into the last time, upper one When the non-eyesight border detection of secondary progress, eyesight testing result is correct, then eyesight grade is promoted level-one, by the eyesight after promotion Grade is as current eyesight grade.
For example, eyesight grade of upper last time is 1.0, when carrying out non-eyesight border detection, testing result is correct, then by eyesight Grade is promoted to 1.1, then carries out non-eyesight border detection, and testing result is correct, then again arrives eyesight grade promotion level-one 1.2, at this point, by eyesight upgrading 1.2 as current eyesight grade.
The third, if the last eyesight testing result for carrying out non-eyesight border detection is mistake, and last regards Power grade is less than the last eyesight grade for carrying out non-eyesight border detection before, then the last time is carried out non-eyesight by the terminal The eyesight grade of border detection is reduced, and using the eyesight grade after reduction as current eyesight grade.
Since last eyesight grade is less than the last eyesight grade for carrying out non-eyesight border detection before, then illustrate When last time carries out non-eyesight border detection, testing result is mistake.Eyesight detection is carried out again after level-one is dropped in eyesight grade, It is exactly that eyesight grade is dropped level-one, will drop the eyesight of level-one again by last detection again if last testing result is mistake Grade is as current eyesight grade.
For example, the eyesight grade of upper last time is 1.0, when carrying out non-eyesight border detection, testing result is mistake, then will be upper The eyesight grade of last time reduces level-one, drops to 0.9, then carry out non-eyesight border detection, when eyesight grade is 0.9, non-eyesight The testing result of border detection is mistake, then eyesight grade is reduced to 0.8, eyesight grade 0.8 is current eyesight grade.
After current eyesight grade determines, terminal is according to the mapping relations of eyesight grade, measuring distance and test pattern, really Fixed currently detected measuring distance and the current corresponding test pattern of eyesight grade, and by determining test pattern include On the display screen of terminal, terminal is according to the user behavior recognized and the test pattern of display, and terminal is according to the use recognized The test pattern of family behavior and display determines eyesight testing result.
After eyesight testing result determines, if it is currently non-eyesight border detection, and current eyesight grade is highest Eyesight grade, then using highest eyesight grade as the eyesight of user；If being currently non-eyesight border detection, and current regard Power grade is minimal visual acuity grade, then using minimal visual acuity grade as the eyesight of user；If being currently non-eyesight border detection, And current eyesight grade is not highest eyesight grade, nor minimal visual acuity grade, then make determining eyesight testing result For the last eyesight testing result for carrying out non-eyesight border detection.
That is, when carrying out non-eyesight border detection, if testing result is correct always, eyesight grade is promoted, Because there are one highest levels for eyesight grade, for example eyesight grade 1.5 is eyesight highest level, then when eyesight grade is promoted to most When high-grade 1.5, the eyesight by highest eyesight grade 1.5 as user.
If testing result is mistake always, eyesight grade reduces, because there are one the lowest class for eyesight grade, such as 0.1 is the lowest class of eyesight grade, then when eyesight grade is reduced to lowermost level 0.1, by 0.1 conduct of lowermost level eyesight grade The eyesight of user.
If current eyesight grade neither highest eyesight grade nor minimal visual acuity grade, by determining eyesight Testing result is as the last eyesight testing result for carrying out non-eyesight border detection.
For example, if when the last time carries out non-eyesight border detection, testing result is mistake, then eyesight grade is reduced by one Grade is detected into current eyesight grade, if current eyesight grade is not minimal visual acuity grade, by current eyesight testing result As the last eyesight testing result for carrying out non-eyesight border detection, continue to detect.
For another example, if the last time carries out non-eyesight border detection, testing result is correct, then promotes eyesight grade Level-one is detected into current eyesight grade, if current eyesight grade is not highest, using current eyesight testing result as Last time carries out the eyesight testing result of non-eyesight border detection.
If the eyesight grade that the last time carries out non-eyesight border detection carries out non-eyesight boundary inspection before more than last The eyesight grade of survey, and the last eyesight testing result for carrying out non-eyesight border detection is mistake, then the terminal determine into Row eyesight border detection.
For example, the eyesight grade of last non-eyesight border detection is 1.0, last time carries out regarding for non-eyesight border detection Power grade is 0.9, then when illustrating upper last time non-eyesight border detection, testing result is correct, and eyesight grade promotion level-one arrives Eyesight grade 1.0, that is, last non-eyesight border detection eyesight grade, if to last eyesight grade 1.0 carry out Detection, testing result is mistake, by should normally reducing eyesight grade, being reduced to 0.9 and continuing to detect, but eyesight grade is Detection has been carried out when 0.9, testing result is correct, that is, the eyesight grade detection that upper last time carries out, so working as eyesight When the testing result that grade is 1.0 is mistake, it cannot be degraded again to eyesight grade and be had detected again, but to carry out eyesight side Boundary is detected, that is, if last eyesight testing result is mistake, terminal carries out eyesight border detection.
If the eyesight grade that the last time carries out non-eyesight border detection carries out non-eyesight boundary inspection before less than last The eyesight grade of survey, and the last eyesight testing result for carrying out non-eyesight border detection be it is correct, then the terminal determine into Row eyesight border detection.
For example, the eyesight grade of last non-eyesight border detection is 1.0, last time carries out regarding for non-eyesight border detection Power grade is 1.1, then when illustrating upper last time non-eyesight border detection, testing result is mistake, and eyesight grade reduction level-one arrives Eyesight grade 1.0, then when being detected to eyesight grade 1.0, if testing result is correct, it should carried out to eyesight grade Upgrading, is raised to eyesight grade 1.1, and non-eyesight border detection is carried out to eyesight grade 1.1, but when eyesight grade is 1.1, detection As a result it is mistake, that is, the detection that upper last time carries out, so when it is correct that eyesight grade, which is 1.0 testing results, it cannot be right Eyesight grade 1.1 carries out non-eyesight border detection again, then needs to redefine eyesight boundary, carry out eyesight border detection. Exactly if the last eyesight grade for carrying out non-eyesight border detection carries out non-eyesight border detection before being less than the last time Eyesight grade, and the last eyesight testing result for carrying out non-eyesight border detection is correct, then terminal carries out eyesight boundary inspection It surveys.
Terminal, which determines, carries out eyesight border detection, then to determine current eyesight grade when eyesight border detection.Below Current eyesight grade when four kinds of situations being divided to determine eyesight border detection.
The first situation, if being currently eyesight border detection, and the last time is non-eyesight border detection, and it is last into The eyesight grade of the non-eyesight border detection of row is less than the last eyesight grade for carrying out non-eyesight border detection before, and last The eyesight testing result for carrying out non-eyesight border detection is correct, then using last eyesight grade as current eyesight grade.
For example, eyesight grade of upper last time is 1.0, non-eyesight border detection is carried out, testing result is mistake, then by eyesight etc. Grade is reduced to 0.9, and eyesight grade 0.9 carries out non-eyesight boundary as last eyesight grade, to last eyesight grade 0.9 and examines It surveys, if eyesight testing result is correct, the current eyesight grade by eyesight grade 0.9 as eyesight border detection.
The second situation, if being currently eyesight border detection, and the last time is non-eyesight border detection, and it is last into The eyesight grade of the non-eyesight border detection of row is more than the last eyesight grade for carrying out non-eyesight border detection before, and last The eyesight testing result for carrying out non-eyesight border detection is mistake, then reduces last eyesight grade, and will be after reduction Eyesight grade as current eyesight grade.
For example, eyesight grade of upper last time is 1.0, non-eyesight border detection is carried out, testing result is correct, then by eyesight etc. Grade is promoted to 1.1, and eyesight grade 1.1 carries out non-eyesight boundary as last eyesight grade, to last eyesight grade 1.1 and examines It surveys, if eyesight testing result is mistake, by the other eyesight grade of the low level-one of eyesight grade 1.1 1.0 as regarding currently Power grade.
The third situation, if it is currently eyesight marginal testing, and the last time is eyesight border detection, and last eyesight The eyesight testing result of border detection is mistake, then the terminal carries out the last eyesight grade for carrying out eyesight border detection It reduces, and using the eyesight grade after reduction as current eyesight grade.
For example, last carry out eyesight border detection, last eyesight grade is 1.0, and eyesight testing result is mistake, If current eyesight detection is also eyesight border detection, last eyesight grade 1.0 is reduced to eyesight grade 0.9 by terminal, And by eyesight grade 0.9 as current eyesight grade.
4th kind of situation, if it is currently eyesight marginal testing, and the last time is eyesight border detection, and last eyesight The eyesight testing result of border detection be it is correct, then the terminal using the last eyesight grade for carrying out eyesight border detection as Current eyesight grade.
For example, the last time is eyesight border detection, last eyesight grade is 1.0, eyesight testing result be it is correct, such as Fruit current eyesight detection is also eyesight border detection, then terminal by last eyesight grade 1.0 as current eyesight grade.
After the eyesight grade determination for carrying out eyesight border detection, terminal is according to the user behavior recognized and the detection of display Figure, after determining that eyesight testing result, eyesight testing result determine, including three kinds of possibilities.
The first, if it is currently eyesight marginal testing, and the eyesight of the current eyesight grade for carrying out eyesight border detection The correct number of testing result reaches given threshold, then the terminal is using the current eyesight grade for carrying out eyesight border detection as use The eyesight at family.
Here eyesight border detection is described in detail, sets a threshold value first, for example threshold value is set as three, then into When row eyesight border detection, current eyesight grade can be detected three times, if the testing result detected three times is all just Really, then using current eyesight grade as the eyesight of user；It, will if the testing result detected three times is wrong at least once Current eyesight grade reduces level-one, is detected three times to the eyesight grade after reduction.
Threshold value is set as three, when carrying out eyesight border detection to current eyesight, if first time testing result is mistake, It is detected without second and third time, eyesight grade is directly reduced into level-one, then carry out eyesight border detection, if for the first time Testing result is correct, and second of testing result, which is mistake, reduces eyesight grade then without third time eyesight border detection Level-one, then eyesight border detection is carried out, if testing result is all correct three times, stop eyesight detection.
As shown in fig. 7, for the schematic diagram of eyesight border detection, by taking threshold value is three times as an example.Current eyesight grade is determined Afterwards, three times to the detection of current eyesight grade, testing result is all correct three times, then using current eyesight grade as the eyesight of user, If testing result is not all correct three times, current eyesight grade is reduced into level-one, three are carried out to the eyesight grade after reduction Secondary detection.
It second, if the eyesight testing result for being currently eyesight marginal testing, and determining is mistake, and is currently regarded The eyesight grade of force boundary detection is not minimal visual acuity grade, then the terminal is using determining eyesight testing result as the last time Carry out the eyesight testing result of eyesight border detection.
For example, the lowest class of eyesight detection is 0.1, and it is currently eyesight border detection, current eyesight grade is 1.0, Eyesight testing result is mistake, then terminal is using determining eyesight testing result as the eyesight of last type eyesight border detection Testing result.
The third, if the eyesight testing result for being currently eyesight marginal testing, and determining is mistake, and is currently regarded The eyesight grade of force boundary detection is minimal visual acuity grade, then the terminal is using minimal visual acuity grade as the eyesight of user.
For example, the lowest class of eyesight grade is 0.1, current eyesight grade is 0.1, when carrying out eyesight border detection, Testing result is mistake, then the eyesight by eyesight grade 0.1 as user.
After user's eyesight determines, terminal can record this eyesight testing result, preserve in the terminal, and according to face figure As distinguishing user.After user's repeated detection, the eyesight data that terminal is detected according to the time and every time draw the variation of user's eyesight Curve, as shown in Figure 8.Fig. 8 is user's eyesight change curve schematic diagram of terminal record, and eyesight 1.0 regards for standard in curve graph Power, the eyesight that user detected before 80 days are that the eyesight detected before 1.2,22 days is 1.1, and eyesight is declined at this time, and terminal is reminded User's visual impairment provides rational scheme protection eyesight, such as when the daily time for reducing using terminal or using terminal The distance between eyes and screen are made to be maintained at other than 30cm etc..
