When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Fig. 2 is a kind of schematic flow diagram of fingerprint identification method shown according to an exemplary embodiment.The present embodiment institute
The method shown can be adapted for terminal, such as mobile phone, tablet computer etc., and the terminal includes being made of multiple fingerprint sensors
Fingerprint sensor array, the fingerprint sensor can be photoelectric sensor, for generating electric signal according to the light sensed.
As shown in Fig. 2, fingerprint identification method shown in this implementation may comprise steps of：
In step sl, when receiving range determine instruction, if the fingerprint area sensed is more than preset area, according to
The brightness for the light that the fingerprint sensor array senses determines brightness range.
In one embodiment, range determine instruction can be inputted by user, can also be when user executes certain operations
It automatically generates.
Such as in acquisition user fingerprints for the first time, range determine instruction can be automatically generated, and work as and sense user fingerprints
Area be more than preset area when, the brightness of the light sensed according to the fingerprint sensor array determines brightness range.
Such as after acquisition user fingerprints for the first time, user can with input range determine instruction, in user by finger
When being placed on fingerprint identification region, user fingerprints are not identified, and it is pre- to be to determine whether the fingerprint area sensed is more than
If area, and it is more than preset area in the fingerprint area sensed, according to the brightness for the light that the fingerprint sensor senses
Determine brightness range.After this, the fingerprint that can further identify user, can also end operation.
In one embodiment, the fingerprint area sensed can be the area of user's finger covering fingerprint identification region,
Wherein it is possible to determine that user's finger covers the face of fingerprint identification region according to the quantity for the fingerprint sensor for receiving light
Product can also determine the area of user's finger covering finger-print region by touch sensing.
In one embodiment, preset area can be configured as needed, but be the need to ensure that when fingerprint area is big
When preset area, ambient light that fingerprint sensor receives such as is received than the light much less of the fingerprint reflection received
To ambient light fingerprint sensor quantity and receive fingerprint reflection light number of sensors ratio be 1:10, into
One step, the 80% of the area that preset area is the fingerprint identification region can be set accordingly.
In one embodiment, in the case where the fingerprint area sensed is more than preset area, it may be determined that fingerprint passes
The brightness maxima and minimum value for the light that sensor senses, wherein can be using the maximum value as the upper limit of brightness range

It spends in higher environment, ambient light, which is radiated on fingerprint sensor, will cause the recognition result of fingerprint graph larger shadow
It rings, so as to determine target of the brightness of the light sensed in the brightness range in the fingerprint sensor array
Fingerprint sensor, so can according to target fingerprint sensor sensing to light determine fingerprint graph, namely according only to reception
The signal generated to the fingerprint sensor of built-in light source reflection light determines fingerprint graph, avoids according to the finger for receiving ambient light
