Referring to Fig. 1, the first embodiment flow process for a kind of unlocked by fingerprint method of embodiment of the present invention offer is shown
It is intended to.Unlocked by fingerprint method described in the present embodiment, comprises the following steps:
101, fingerprint image is obtained.
Wherein, user presses fingerprint recognition module when, can obtain fingerprint image, this fingerprint image can
For fingerprint image partly or completely, such as, fingerprint image is that the finger of user touches fingerprint recognition mould
The fingerprint image of the contact site of group, or, fingerprint image is that a part for fingerprint recognition module specifies region
The fingerprint image gathered.
Wherein, step 101 can comprise the further steps of:
11) during user presses fingerprint recognition module, N number of sense of described fingerprint recognition module is detected
Answer on electrode by surging, described N is the integer more than 1；
12) obtain and described in described N number of induction electrode, press dynamics M the sensing more than the second predetermined threshold value
The capacitance that electrode is gathered, described M is the integer more than 1；
13) capacitance that described M induction electrode is gathered is converted into fingerprint image.
Wherein, the fingerprint recognition module in step 11 can integrated pressure sensor, to realize fingerprint recognition module
Finger sensing by surging, fingerprint image can be gathered again.Fingerprint recognition module comprises fingerprint recognition chip,
Fingerprint recognition chip can comprise N number of induction electrode, and N is the integer more than 1, and this N number of induction electrode can be
The all or part of induction electrode of fingerprint recognition chip.During user presses fingerprint recognition module,
Fingerprint recognition module can gather fingerprint image, the most corresponding pixel of each induction electrode, and each
Surging correspondence one can be pressed in the position of induction electrode.
Wherein, during pressing fingerprint recognition module due to user, the location sensitive of each induction electrode arrives
Different by surging, thus, if the position of the induction electrode not being depressed by the user detect by pressure
Degree may be 0, and the position of the induction electrode in being depressed by the user region is likely to be 0 by surging, due to
The fingerprint of user's finger is also rough, and therefore, the position of some induction electrodes may be by user's
Finger touches.Therefore, second predetermined threshold value can be set, less than or equal to this second predetermined threshold value,
Then the position of induction electrode is not pressed, if more than this second predetermined threshold value, then the position of this induction electrode being described
Put and be pressed.Second predetermined threshold value can be 0.01N, and 0.1N, 1N, 0.2N, 0.3N etc. do not make at this
Limiting, the second predetermined threshold value can be arranged voluntarily by user, or, system default.Therefore, can be from above-mentioned N
Individual induction electrode determines the electric capacity that pressing dynamics is gathered more than M induction electrode of the second predetermined threshold value
Value, wherein, this M is the integer more than 1 and less than N.
Wherein, capacitance directly can be converted into fingerprint image by step 13, it is achieved in, capacitance is usually 0～1
Between, and the pixel value of fingerprint image is between 0～255, therefore, can directly by the capacitance between 0～1,
