Device detects whether user has use demand for terminal, if terminal determines terminal according to the testing result of acceleration transducer
There are shakings, then determine that there is currently the use demands for being directed to terminal, otherwise determine that there is no the use demands for terminal.?
Determine that user has when needing of using terminal, terminal will light screen, thus the finger pulp loss for guiding user that will be used to unlock
Corresponding region is placed on so that terminal carries out finger scan.But, it regardless of user is carried terminal, is either held in
On hand, it is also located in packet, as long as user has movement, terminal more or less can all shake.And in the related technology
Terminal when detecting user's use demands, can't distinguish by it is this it is inevitable shaking have use demand with user when
Shaking distinguish, this also results in the shaking of the non-unlock of terminal that can also be detected as the performance that user has use demand, in turn
Screen is lighted when user does not need using terminal and carries out finger scan.
In order to solve in the related technology, because deciding whether to light screen progress based on the testing result of motion sensor
The scheme of finger scan easily causes the false triggering that screen is lighted, to waste terminal power, influences asking for terminal cruise duration
Topic, the present embodiment provides a kind of new fingerprinting schemes, refer to a kind of flow chart of fingerprint identification method shown in Fig. 3:
S302: it in the case where ceasing screen state, detects on screen everywhere with the capacitance between touch control object.
In the present embodiment, when terminal is in breath screen state, terminal is no longer merely according to the inspection of motion sensor in terminal
Result is surveyed to determine the use demand of user, but selected according to determining use with the capacitance between touch control object everywhere on screen
Whether family has use demand.
It is understood that screen can't usually distinguish the touch-control when touched for terminal
What object is.Existing screen is all touch screen, and user can touch on the screen under the premise of not by other equipment
Operation is touched, so touch control object is usually the finger of user.Certainly, in some cases, touch control object is also likely to be touch control operation pen.
But, it is contemplated that user needs using unlocked by fingerprint screen, so, if user has use demand to terminal, touching here
Controlling object should be user's finger.
It is understood that capacitor, and the electricity will be constituted between touch control object and screen when touch control object is close to screen
The capacitance of appearance will constantly increase with touch control object with the reduction of distance between screen.So if touch control object touches screen
Curtain, then the capacitance of screen corresponding position will be much larger than 0, and the capacitance at the position that other are not contacted with touch control object can
It can be exactly 0 either close to 0.
So in the present embodiment, terminal can be monitored in the case where ceasing screen state and be formed between touch control object everywhere on screen
Capacitance.For example, under the TP (touch screen controller) of terminal is in running order, screen can be monitored in the case where ceasing screen state
Each point is the same as the capacitance formed between touch control object on curtain.
S304: judging terminal currently according to capacitance detecting result whether there is fingerprint recognition demand.
After getting capacitance detecting result, terminal can currently whether there is finger based on the capacitance detecting result judgement
Line identifies demand.If the determination result is YES, then enter S306, otherwise terminate process.
If should be appreciated that there is currently fingerprint recognition demand, user is generally only to place that oneself screen locking can be solved
The finger of curtain on a terminal screen, but if user only because hold terminal and touched terminal screen, then user's body
The part of body and screen contact is usually more than a finger.So terminal can be with base in some examples of the present embodiment
It determines whether to refer to one shown in Fig. 4 there are fingerprint recognition demand in contact situation of the touch control object with terminal screen
Kind flow chart:
S402: the contact area between touch control object and screen is determined according to capacitance detecting result.
Capacitance detected by each point on screen is recorded in capacitance detecting result, namely have recorded coordinate position with it is right
The mapping relations between capacitance are answered, terminal can determine the contact zone between touch control object and screen according to the capacitance of each point
Domain.Under theoretical case, the capacitance for the coordinate points that screen is contacted with touch control object is much larger than 0, and those are not covered by touch control object
Detected capacitance should be close to 0 in the coordinate points blocked.In some examples of the present embodiment, terminal can be straight
The coordinate points for filtering out that capacitance is non-zero value are connect, these coordinate points is then based on and determines contact zone between touch control object and screen
Domain.In view of in actual conditions, user is when having use demand to terminal, body other parts, for example, face be also possible to
Each point forms capacitor on screen, but these capacitances can not embody whether user has use demand for terminal.So
In the other example of the present embodiment, in order to exclude the influence of these capacitances, terminal can be powered on filter record screen
Capacitance is greater than the coordinate of the position of predetermined capacitive thresholding, and the value for here presetting at capacitor thresholding is greater than 0, and according to these capacitances
Greater than the contact area that the coordinate points of predetermined capacitive thresholding determine touch control object and screen.
S404: judge whether the profile of contact area matches with pre-stored single finger image outline.
It is understood that terminal, which " can be drawn ", goes out contact area based on the multiple coordinate points determined, then determine
The chamfered shape of contact area out, Fig. 5 show a kind of schematic diagram of contact area, and Fig. 6 shows the wheel of contact area in Fig. 5
Wide schematic diagram.In some examples of the present embodiment, terminal can draw out contact area according to the coordinate points filtered out
Then image carries out edge extracting using Edge extraction basis from image, gets the profile of contact area.Here into
Row Edge extraction technology can be based on Robert's Operator Method, Laplace operator method etc..
In the other example of the present embodiment, terminal directly can also be determined to connect according to the coordinate points filtered out
Touch region contour, and do not have to first draw out true contact area image: terminal by comparing each coordinate transverse and longitudinal coordinate size,
The edge coordinate of contact area can be directly determined out.It is illustrated by taking certain a line coordinate points as an example:
It is assumed that having 5 × 5 coordinate points on screen, wherein the capacitance detecting result situation of each coordinate points such as 1 institute of table on the 2nd row
Show:
Table 1
So the coordinate points that capacitance is greater than predetermined capacitive thresholding include (2,2), (3,2) and (4,2) in the 2nd row,
Then terminal can determine that the edge coordinate point in the 2nd row coordinate points includes (2,2) and (4,2), be also similar for other rows.It is logical
This mode is crossed, terminal can filter out the transverse edge coordinate of every a line.Similar mode, terminal can filter out each column
Longitudinal edge coordinate, so that terminal can directly determine out contact image edge according to each edge coordinate filtered out,
That is the profile of contact image.
Then, terminal will acquire contact zone outline with the single finger image outline being stored in advance in terminal into
Row compare matching, with determine currently with the touch control object of screen contact whether be user a finger.Single finger mentioned here
Image outline refers to the image of only one finger, beyond all doubt, and the image including two or more fingers is not
Belong to single finger image, does not include that the image of finger is also not so-called single finger image.The only profile of contact area and one
When the outline of a finger, terminal can just determine that there is currently fingerprint recognition demands, therefore enter S406；Otherwise enter
S408。
It is understood that the single finger image that terminal is stored may include it is multiple, this be primarily due to user will
When one finger is placed on a terminal screen, posture is not unique, this also results in the even same finger to connect with terminal screen
Touching, but the contact zone outline shape formed is not fully identical.For example, in some cases, the entire finger of user can
On a terminal screen, but in other cases, user only has the finger pulp and screen contact of unlock fingerprint place finger for fitting,
In both cases, the chamfered shape of fit area is entirely different between user's finger and screen.So in the present embodiment
In, terminal can store multiple single finger images, this is primarily to cover user's finger comprehensively as far as possible with a variety of different appearances
The case where gesture and screen contact.
It is clear that the profile of the part single finger image of terminal storage appears likely to meeting unlike the wheel of a finger
Exterior feature, such as under normal circumstances, the profile of a finger should as shown in fig. 7, to form contact zone outline shown in Fig. 7,
Then require all being bonded with terminal screen for user's finger.In order to which the position where adapting to user's finger tightly fingerprint connects with screen
The case where touching, allows terminal also can determine that there is currently fingerprints according to finger and the profile in screen contact region in these cases
Identification demand, then terminal can also store the single finger image similar to Fig. 8.In single finger image shown in Fig. 8, image border is
Irregular strip closed figure.
S406: determine that there is currently fingerprint recognition demands for terminal.
If terminal, which can determine, to be worked as when the outline of the profile of contact area and the pre-stored single finger image of terminal
Preceding contact with terminal screen is a finger, and therefore, terminal determines that there is currently fingerprint recognition demands.
S408: determine that there is currently no fingerprint recognition demands for terminal.
If the profile of the profile of contact area and the pre-stored single finger image of terminal mismatches, such as in contact area
There are the shapes that the profile of the profile of multiple fingers or contact area is not finger, although then terminal can determine currently
There are touch control objects to contact with terminal screen, but user has no the demand of using terminal, namely does not need currently to carry out fingerprint knowledge
Not.
S306: it lights screen and carries out finger scan.
If terminal by judgement, determine there is currently fingerprint recognition demands, then it, which can control, lights screen, so as into
Row fingerprint recognition.In some examples, terminal can be lighted entire screen, be worked as in the other example of the present embodiment
In, terminal can also only light the screen area that can support finger scan:
It is understood that the terminal in the present embodiment can support full frame fingerprint recognition, only half screen can also be supported to refer to
Line identification.If terminal supports full frame fingerprint recognition, the entire screen of terminal supports fingerprint recognition.If terminal only supports half
Shield fingerprint recognition, just then illustrate only have some specific regions to support fingerprint recognition on terminal screen, in this case, in order to drop
Low power consumption of terminal, terminal may not necessarily at least light the region for not supporting fingerprint recognition on screen.
In some examples of the present embodiment, terminal can't light the whole region of finger scan on screen, because
For user when carrying out fingerprint recognition, finger can tightly touch some position, in this case, if lighting support
The whole region of scanning is simultaneously scanned, then not only increases the power consumption of terminal, while also increasing terminal in finger scan side
The process resource in face occupies.So in the present embodiment, terminal only can determine one from the region for supporting scanning on screen
A scanning area, then lights the scanning area and finger scan.In general, the area of scanning area is less than on screen
Support the region of finger scan.Fig. 9 shows a kind of terminal 9 for supporting full frame fingerprint recognition, but in the screen of the terminal 9 90
On, the scanning area 91 that terminal 9 is lighted is only the region of a very little, and the whole region of non-screen 90.
In the present embodiment, terminal is referred to following several exemplary modes and determines scanning area from screen:
Mode one:
Terminal determines the contact area of touch control object and screen according to capacitance detecting result first, then according to contact area
Shape determines fingerprint location, then determines scanning area on the screen further according to fingerprint location.Already explained above
The scheme of contact area is determined according to capacitance detecting result, which is not described herein again.It is worth noting that because terminal is determining currently
When whether having fingerprint recognition demand, the contact area between touch control object and screen was determined according to capacitance detecting result, because
This in the stage for determining scanning area, terminal can directly utilize before as a result, need not again according to capacitance detecting result
It determines, the processing time can be reduced in this way.
So-called " fingerprint location " is the region where user's finger fingerprint, and for terminal, theoretically it is only needed
Fingerprint location on screen is lighted, and finger scan is carried out to the region, fingerprint recognition can be realized.So terminal can will shield
Include fingerprint location as scanning area namely scanning area comprising the region including the fingerprint location on curtain.Although
Before terminal starts finger scan, it is difficult accurately to determine fingerprint location, but based on contact area between touch control object and screen
Shape, terminal can substantially deduce fingerprint location.
Mode two:
Terminal determines the contact area of touch control object and screen according to capacitance detecting result first, is then existed according to contact area
Determine that scanning area, scanning area are on screen comprising the region including contact area on screen.
In the second way, terminal is similarly to determine scanning area based on the contact area between touch control object and screen
Domain, but in mode one unlike, in mode two, terminal is not necessarily to according to contact area determine fingerprint location, and
Be directly using comprising the screen area including contact area as scanning area.
Mode three:
Terminal determines the contact area of touch control object and screen according to capacitance detecting result first, then according to preset area
Domain-area maps relationship determines scanning area corresponding with contact area affiliated area.
It must include connecing between touch control object and screen in the scanning area that terminal finally determines in mode two
Region is touched, in mode three, although scanning area is also determining according to contact area, but in this mode, not
It is therefore, also to have very much in the scanning area determined according to mode three directly using the region where contact area as scanning area
May and contact area not be included.
Zones, Zone mapping relations can be stored in advance in terminal, include contact in the zones, Zone mapping relations
Corresponding relationship between region and scanning area, in this way, after terminal determines contact area, so that it may directly be reflected according to this
The relationship of penetrating determines corresponding scanning area.
In above-mentioned example, terminal is to determine scanning area based on the capacitance detecting result on screen everywhere,
In the other example of the present embodiment, when terminal according to capacitance detecting result determine there is currently fingerprint recognition demand with
Afterwards, it may be considered that determine scanning area, such as writing in example in the present embodiment by other means, terminal can be based on
User determines scanning area to the grip of terminal.
No matter by any in above-mentioned several ways, after determining scanning area, terminal, which can control, to be lighted
Scanning area, and finger scan is carried out in scanning area.
S308: fingerprint recognition is carried out according to scanning result.
After terminal obtains scanning result, fingerprint recognition, such as the picture number that scanning is obtained can be carried out to the result
It is compared according to the fingerprint characteristic data with pre-stored legitimate user, determines whether the two matches, if matching, it is determined that when
Preceding user is legitimate user, and therefore, terminal can carry out unlocking screen.If the terminal determine that scanning result with it is pre-stored
The fingerprint characteristic data of legitimate user mismatches, then terminal can be refused to carry out unlocking screen.
Fingerprint identification method provided in this embodiment, on the one hand, determined based on the capacitance detecting result on screen everywhere
A possibility that whether user currently has terminal use demand, can reduce use demand erroneous judgement, reduces the mistake that terminal screen is lighted
Trigger probability；On the other hand, when electricity screen carries out finger scan, the whole region of screen is not lighted directly, but
Scanning area is only lighted, power consumption needed for can reduce Terminal fingerprints identification extends terminal cruise duration, enhances user's body
It tests.
Second embodiment
The advantages of in order to make those skilled in the art more understand fingerprint identification method in previous embodiment and details, this reality
Applying example will continue to be illustrated fingerprint identification method in conjunction with specific example, referring to Figure 1 the flow chart shown in 0:
S1002: in the case where ceasing screen state, each point is the same as the capacitance between touch control object on detection screen.
In the present embodiment, terminal can monitor the capacitor formed between touch control object everywhere on screen in the case where ceasing screen state
Value.Optionally, the TP of terminal is still in working condition in the case where ceasing screen state, can monitor on screen each point with touch control object it
Between the capacitance that is formed, and the capacitance that will test be associated with coordinate value after be sent to terminal handler.
S1004: capacitance is greater than the coordinate of the position of predetermined capacitive thresholding on record screen.
On getting screen each point respectively with the capacitance of the capacitor formed between touch control object after, terminal can reject that
A little capacitances are less than or equal to the coordinate value of the point of predetermined capacitive thresholding, only retain the capacitance detected and are greater than predetermined capacitive thresholding
Coordinate value.
S1006: the contact area of touch control object and screen is determined according to each coordinate of record.
According to each coordinate value that screening retains, terminal can be determined to be formed by contact zone between touch control object and screen
Domain.
S1008: judge contact area profile whether the outline with any one pre-stored single finger image.
If the determination result is YES, then enter S1010, otherwise terminate process.
After determining contact area, terminal can determine the profile and pre-stored single finger image of contact area
Outline, however, it is determined that result be it is yes, then illustrate user currently and be to place on a finger on the screen, therefore, according to
From the point of view of family carries out the habit of terminal unlocking, user should be currently that there are the expectations of unlocked by fingerprint terminal, so, it can enter
S1010 is to carry out finger scan.If by judging that active user not places a finger on the screen, but simultaneously
It placed multiple fingers on the screen, then user should be by chance to place finger on the screen when holding terminal
, and non-user has unlock to be intended to.Alternatively, by judgement after determine place on the screen not be user finger, and
It is the claw etc. of pet, then all illustrate that user is current and endless use demand, terminal are not necessarily to carry out fingerprint recognition, from
It so also need not just carry out subsequent finger scan process.
S1010: contact area is lighted as scanning area.
In the present embodiment, terminal is directly using the contact area of user's finger and screen as scanning area, so, user
The placement region of finger on the screen just will do it finger scan, this also just determines the terminal of the present embodiment, even be in
It ceases under screen state, user is in unlock, it is only necessary to which the finger that will correctly unlock is individually placed on the screen, without being moved
Fingerprint recognition can be completed in dynamic and other operations, realizes terminal unlocking.
In above-mentioned example, terminal is that scanning area, institute are determined based on the contact area of user's finger and screen
With substantial, terminal still determines scanning area based on the capacitance detecting result of each point on terminal screen.In the present embodiment
Other example in, terminal can determine scanning area based on other information.Such as terminal can be worked as based on user
The preceding grip to terminal determines a scanning area, so that the scanning area determined more is agreed with, user is current to be held
Posture is held, facilitates user that finger is placed into corresponding scanning area to realize finger scan:
In the present embodiment, what the back side and side of terminal were all arranged has sensor, works as in other examples of the present embodiment
In, sensor can be provided only on terminal side or the back side.By the detection of these sensors, it is available to user's hand with
The fit area of terminal.Sensor mentioned here may include that pressure sensor, infrared sensor and temperature sensor etc. pass
At least one of sensor.Certainly the combination of two or more in these sensors is also feasible come the detection for realizing grip
's.
User when holding terminal, hand can with the terminal back side, side or simultaneously contacted with the back side, side.
Moreover, user, under left-handed posture and the right hand grip both of which when operating terminal, hand is bonded with terminal
Region is different.
For example, when user's left-handed terminal, the shape of the finger or palm of left hand and terminal back side patch region
With user with the position of the finger of right hand when right hand gripping terminal or palm and terminal back side fit area, shape, towards all
It is not identical.When user operates terminal with left-handed posture, left hand is bound to be bonded with terminal left side,
In some cases, the finger of left hand four of user will not be bonded with terminal right side, but be directly placed at the terminal back side to terminal
Its supporting role.In this case, by the way that the sensor senses user left hand at left and right sides of terminal and terminal side is arranged in
Fit area can easily judge that user currently belongs to left-handed posture to the operation of terminal.So as user couple
When the grip position difference of terminal, the position of fit area can have difference.
Under other situations, all or part in four fingers of user's left hand can be also bonded with the right side of terminal, this
When, the left side and right side of terminal are bonded with user's hand, however, a left side for terminal left side and user's hand
Side fit area is with the right side fit area of right side and user's hand or distinct: terminal left side and user's palm
It is bonded to the region of tiger's jaw, therefore left side fit area is continuous, and right side is bonded with all or part in the finger of left hand four,
And the finger of user in most cases can't be in the state closed up completely, therefore, it is generally the case that right side fitting
Region is discrete.This detection mode is based primarily upon the shape of fit area to judge that the current grip position of user belongs to left hand
It holds or the right hand is held, it is to be understood that this scheme detected based on fit area shape is also applied for terminal
The detection at the back side: when user's left-handed terminal, the fit area on the left of the back side is continuous, and fit area on the right side of the back side
It may be discrete.Therefore, when grip position difference of the user to terminal, user's hand and the shape of terminal fit area are had
Institute is different.
In addition, user has the gripping direction of terminal based on practical experience it is found that user is under two kinds of one-hand operating formats
Apparent difference.For example, holding direction when user is with left-handed terminal and being directed towards upper right, this is two sides
The minimum point A of the left side fit area feature more slightly lower than the minimum point B of right side fit area is shown on the fit area in face.This
When, the line AB of two sides fit area minimum point is directed towards upper right, and here it is the directions of fit area.
So other than determining user to the grip position of terminal according to the position of fit area, shape, it can also be according to patch
The direction in region is closed to determine grip position.It is this to be carried on the back based on fit area towards to determine that the mode of user's grip position is also applied for terminal
The fit area in face and user's hand becomes apparent moreover, holding direction and overleaf embodying on fit area: when user is with left hand
When holding terminal, have the tendency that incline upward, concrete embodiment are overleaf pasted to the right from lower left side very significantly at the terminal back side
It closes and is lower than right side on the left of region.
Above-mentioned introduction is but beyond all doubt mainly by user by taking left-handed terminal as an example, and user is held eventually with the right hand
The case where the case where end should be with left-handed terminal is corresponding, for example, when user is hold by one hand terminal using the right hand, and use
All or part in four fingers of the family right hand is bonded with the left side of terminal.As shown in figure 8, the right side and left side of terminal are equal
It is bonded with user's hand, but terminal right side is slapped to the region of tiger's jaw with user's right hand and is bonded, therefore right side fit area is
Continuously, and left side is bonded with right finger, since the finger of user in most cases can't be in completely closing up
State, therefore, right side fit area is continuous.So it is also feasible for detecting right hand grip position according to fit area shape
, no longer other situations of right hand grip position are described in detail here, left side grip position is directly shown respectively with table 2 and is held with right side
Under appearance, the characteristics of the features of shape of fit area and the corresponding gripping direction in fit area:
Table 2
In some examples of the present embodiment, terminal can be individually according to the position of fit area, shape, towards several
At least one of factor determines the grip position of user, but in order to promote the accuracy of detection, some examples of the present embodiment
In the middle, terminal can also determine that the current grip position of user is left hand according to the position of fit area, shape and direction simultaneously
Grip position or right hand grip position, namely determining terminal on earth is in left-handed posture or right hand grip.
In some other example of the present embodiment, terminal before control lights contact area as scanning area,
Also it needs to be determined that motion sensor detects the shaking of terminal in nearest a period of time, optionally, terminal judgement movement is passed
Whether sensor detects the shaking of terminal when away from current time in the period of a length of T, if the determination result is YES, terminal just meeting
Light scanning area.So lighting terminal scanning area in these examples and needing " opening dual fail-safe ": guaranteeing terminal most
It is close to there is shaking, guarantee that user places single finger on the screen.In this case, terminal can just light scanning area progress
Finger scan, this dual fail-safe mechanism reduces individually determines user with the presence or absence of use according to the testing result of motion sensor
Demand and individually according to capacitance detecting result determine user with the presence or absence of use demand scheme in false triggering probability, promoted
To the accuracy of user's use demands detection, be conducive to while guaranteeing that user unlocks experience, reduce power consumption of terminal and
To the occupancy of terminal processes resource, optimize allocation of resources.
S1012: finger scan is carried out to scanning area, and fingerprint recognition is carried out according to finger scan result.
After determining scanning area, terminal, which can control, lights scanning area, and carries out fingerprint in scanning area and sweep
It retouches, to carry out fingerprint recognition according to finger scan result, it is determined whether unlocking screen can be carried out.
Fingerprint identification method provided in this embodiment not only can more accurately judge user according to capacitance detecting result
There is endless use demand, but also can directly light user's finger and screen in the case where determining that user has use demand
The contact area of curtain is not other behaviour so that finger is directly placed on the screen of breath screen by user as scanning area
Fingerprint recognition can be completed, realize end results, in the case where reducing power consumption of terminal, simplify the user behaviour of terminal unlocking
Make process, enhances user experience.
