Picture.
Fig. 2A diagrammatically illustrates the flow chart of information processing method according to an embodiment of the present invention.
As shown in Figure 2 A, the information processing method may include operation S201~operation S203.
In operation S201, first image with biological characteristic is obtained, the first image is the biological characteristic of screen
Acquired image when pickup area is illuminated with the first brightness, the physical characteristics collecting region are the display area of the screen
At least partly.
Wherein, the biological characteristic can be face characteristic, fingerprint characteristic etc., and first brightness can be current for user
The screen intensity currently in use that eyes can be made pleasant.Due between the image acquisition device under face or fingerprint and screen
Light transmitance it is lower so that the facial image or fingerprint image that acquire under first brightness may be able to satisfy the need of certification
It asks, it is also possible to not be able to satisfy the demand of certification.But in order to avoid often such that screen is in high brightness at image acquisition region
Screen caused by lower work is abnormal, and the present invention first attempts to acquire image under lower brightness.
In one embodiment, the biological characteristic is face characteristic, (can refer to Figure 1A by shielding lower camera
Shown in dashed circle above middle mobile phone screen) facial image is acquired, the light that screen issues at this time can be used as main light source or auxiliary
Help light source to come lighting consumer face and collect the facial image being more clear in order to shield lower camera, for example, can with sunlight,
Light etc. is used as main light source, and the light that Mobile phone screen issues can assist illuminating face to increase the light of face reflection,
In addition it is also possible to directly using the luminous as main light source of screen, when as there is no lighting source at night.Wherein, face characteristic can be with
Including histogram feature, color characteristic, structure feature etc., extracting method can be compared with the face characteristic extraction side of technology
Method.During obtaining the first image, first screen intensity can be remained unchanged, i.e. the screen that is being currently used of user
Curtain brightness, the facial image that the camera under screen is obtained under the screen intensity is as the first image.
In another embodiment, the biological characteristic can be fingerprint characteristic, and the first image is the first fingerprint image
Picture, first fingerprint image are acquired image when the fingerprint collecting region of screen is illuminated with the first brightness.
This programme in order to facilitate understanding is mainly illustrated so that the biological characteristic is fingerprint characteristic as an example below.
In another embodiment, the biological characteristic can be fingerprint characteristic, and the first image is the first fingerprint image
Picture, the method can also include operation S204.
In operation S204, if obtaining the operational order for starting fingerprint identification module, the finger of the screen is controlled
Luminance parameter before line pickup area maintains the screen is constant.Correspondingly, obtaining first fingerprint image can wrap
It includes: based on illuminating the fingerprint collecting region with the luminance parameter before maintaining the screen to obtain first fingerprint image
Picture.That is, when receiving the operational order of starting fingerprint identification module, so that when screen keeps being currently displaying
Brightness, and carry out fingerprint image acquisition.
Fingerprint image is acquired under brightness when being currently displaying, user's bring can be given to avoid due to jump in brightness
Sense of discomfort and lofty sense.
Further, the method can also include operation S205.
In operation S205, if first fingerprint image meets first preset condition, with first fingerprint
Image carries out fingerprint recognition, and maintains the luminance parameter in the fingerprint collecting region constant.
Specifically, if first fingerprint image meets first preset condition, show that the first fingerprint image is full
Sufficient authentication requesting, can use first fingerprint image and carries out authentication, be not necessarily to that the brightness of screen is turned up at this time.
It should be noted that first preset condition can be through one group of experimental calibration as a result, for example, more meeting
Image under few clarity carries out certification successfully ratio how many noise can be being met greater than the clarity threshold of given threshold
Image than under, which carries out certification, successfully ratio can also be greater than the snr threshold etc. of given threshold and pass through machine learning
The first obtained preset condition, it is not limited here.
In operation S202, if the first image does not meet the first preset condition, adjusts the biological characteristic and adopt
The luminance parameter for collecting region is the second brightness.
In the present embodiment, only judge whether first image meets the first preset condition, if whether signal-to-noise ratio is more than to set
Determine whether threshold value, clarity are more than given threshold etc., and it is indirect authenticated using the first image, such as fingerprint recognition or face
Identification.This is because the speed of certification has very big influence to the Experience Degree of user, if being more than certain the time required to certification
Duration, such as 0.5 second etc., it will lead to the impatient of user.And as described above, the image acquired under the first brightness is possible to full
Foot certification demand, it is also possible to certification demand is unsatisfactory for, if directly such as used with the image and standard picture acquired under the first brightness
Preset fingerprint image in family etc. carries out finger print identifying, may it is not clear enough due to the image that is acquired under the first brightness and can not be after
Continuous certification, the verification process spent time are wasted, if improving screen intensity again at this time to obtain to be able to satisfy to authenticate and need
When the fingerprint image asked, it is too long and be unable to satisfy user demand to will lead to authenticated time.In order to solve this problem, in this implementation simultaneously
It is not authenticated using the first image directly, but first judges whether first image meets the first preset condition, such as whether foot
Clear, whether signal-to-noise ratio is sufficiently high etc. is reached, and process the time it takes ratio authenticates, as finger print identifying the time it takes is short
Much, even if the first image is unsatisfactory for the first preset condition, have enough time being turned up screen intensity also to obtain higher screen intensity
The image of lower acquisition.Allowing for the present invention in this way may be implemented to lack as far as possible under the premise of unobvious lengthening authenticated time
The screen of image acquisition region is worked under high light intensity.
In operation S203, second image with biological characteristic is obtained, second image is the biological characteristic of screen
Acquired image when pickup area is illuminated with second brightness, wherein second screen intensity is higher than first screen
Curtain brightness.
In the present embodiment, it can allow to collect the figure for being more in line with certification demand by raising screen intensity
Picture, such as the fingerprint image being more clear or facial image etc..
Correspondingly, the method can also include operation S206.
In operation S206, if second fingerprint image meets first preset condition, with second fingerprint
Image carries out fingerprint recognition, and the luminance parameter for adjusting the fingerprint collecting region is restored to first brightness.
Specifically, if second fingerprint image meets first preset condition, show second fingerprint image
Meet and carry out authenticating required fingerprint image, therefore, can use second fingerprint image and carry out fingerprint recognition.In addition, if
Second fingerprint image meets first preset condition, also shows therefore to adjust without being further continued for acquisition fingerprint image
The luminance parameter in the whole fingerprint collecting region is restored to first brightness, which can start for user in input
Before the operational order of fingerprint identification module or screen intensity this moment, in this way can to avoid user in order to enable ocular comfort and
It needs to reduce screen intensity manually.
Fig. 2 B diagrammatically illustrates fingerprint recognition schematic diagram under screen according to an embodiment of the present invention.
It should be noted that scheme provided by the invention can be implemented in a manner of following two.First way, as long as opening
Dynamic fingerprint recognition mode just controls in this way, for example, user triggers starting fingerprint recognition mould by being unlocked by pressing key etc.
Formula, or start fingerprint recognition mode under state to be paid, at this point, starting to execute operation as described above.The second way,
With reference to shown in Fig. 2 B, operation as described above is only just executed when finger is pressed into the fingerprint collecting region, for example, with
Family triggers starting fingerprint recognition mode by being unlocked by pressing key etc., does not first execute operation as described above at this time, until image
When pickup area has detected that fingerprint is located at fingerprint collecting region, just start to execute operation as described above.
Wherein, the second way has the advantage that: it is possible, firstly, to further shorten so that screen is in high brightness Working mould
Operating time under formula is likely to execution and mentions in addition, may be implemented in this way when the finger of user is located on fingerprint collecting region
The operation of the brightness in fingerprint collecting region is risen, and the finger of user can block the fingerprint collecting region, it can block fingerprint
The strong light that pickup area issues, avoids the strong light generated suddenly or brightness change from giving user's bring sense of discomfort.
Fig. 3 A diagrammatically illustrates the flow chart of information processing method according to another embodiment of the present invention.
As shown in Figure 3A, the method can also include: operation S301~operation S302.
In operation S301, before obtaining first fingerprint image, environmental information is obtained, the environmental information includes
Below any one or more: environmental light intensity, environment temperature or ambient humidity.
Since the picture quality obtained in different environments is different, in the ring for the picture quality for being unfavorable for having obtained
In border, as low temperature, high humility, bloom shine environment in, can directly make display screen work under high screen intensity in order to
The fingerprint image that can satisfy certification demand can be collected.Above-mentioned environmental information can use the sensor that equipment itself has and obtain
It takes, can also be through network inquiry and obtain, it is not limited here.
In operation S302, if the environmental information meets the second preset condition, third fingerprint image is obtained, it is described
Third fingerprint image is fingerprint collecting region acquired image when being illuminated with the third brightness of screen, wherein described the
Three screen intensitys are higher than first screen intensity, and second preset condition includes any of the following or a variety of: environment light
It is powerful to be less than temperature threshold or ambient humidity less than humidity threshold in Intensity threshold, environment temperature.
For example, when environmental light intensity is less than 60K lumen (lux) and temperature is room temperature range, it can be in the first screen intensity
Lower acquisition fingerprint image does not have to the first fingerprint image of acquisition when environmental light intensity is greater than 100K lux and temperature less than 0 DEG C, and
Directly screen intensity is adjusted to third brightness, acquires the third fingerprint image under third screen intensity.Wherein, the third screen
Curtain brightness is higher than first screen intensity.
It should be noted that since display screen is generally configured with the function of manual adjustment screen intensity, if this method is automatic
While determining that needs obtain third fingerprint image under third screen intensity, the behaviour of the adjusting screen intensity of user is also received
It instructs, then can preferentially execute the operational order of user's input, for example, the highest priority of the operational order of user's input.
But if the fingerprint image obtained is unsatisfactory for the first preset condition and repeatedly reaches predetermined number of times, it can be believed with display reminding
Breath informs that the fingerprint image quality obtained under user's current screen brightness is unsatisfactory for certification demand, needs that screen intensity is turned up, also
Interactive interface can be provided, ask the user whether to agree to improve screen intensity.
Further, since third screen intensity is that mode is highlighted in one kind, for a long time using being possible to cause screen
Irreversible damage.Therefore, the method can further include following operation: if environmental light intensity is greater than Intensity threshold,
