Step or unit.
Fig. 1 is a kind of flow chart of fingerprint input method according to an exemplary embodiment.The present embodiment provides one
Fingerprint input method is planted, this method can be performed by fingerprint input device.The fingerprint input device can be by hardware and/or soft
The mode of part is realized, and can be integrated in electronic equipment, and the electronic equipment can have fingerprint for smart mobile phone, tablet personal computer etc.
The electronic equipment of sensor or similar fingerprint sensor.Or, it will be understood by those skilled in the art that fingerprint input device is
Electronic equipment.
As shown in figure 1, the fingerprint input method comprises the following steps：
In a step 101, the fingerprint image of current typing is obtained.
In fingerprint typing, user can successively carry out multiple typing, one fingerprint image of each typing correspondence.
For each fingerprint typing, electronic equipment obtains the fingerprint image of current typing.Finger is provided with electronic equipment
Line sensor, the fingerprint sensor can sense the fingerprint on the screen from electronic equipment, generate fingerprint image.
In a step 102, the first finger print information of fingerprint image absolute presupposition feature is determined.
In the step, default feature can be global characteristics and/or local feature.
Wherein, global characteristics can be line type and/or streakline density etc..Line type includes whorl, loop and archwire line
Deng.
Local feature can centered on point, triangulation point, ramification point, starting point, terminal, binding site, dot, ommatidium, spillikin, small
Any of hook and foot bridge etc. are multiple.Each local feature respective position and direction of correspondence in fingerprint image.Line type and line
Line density respective type of correspondence in fingerprint image.
It should be noted that, default feature can be set when electronic equipment dispatches from the factory or user according to individual
What demand was voluntarily set, the disclosure refuses limitation.
Electronic equipment determines the first finger print information of fingerprint image absolute presupposition feature.For example, default be characterized as central point,
First finger print information can be position, direction or type of the fingerprint image with respect to central point；Or, it is default be characterized as central point and
Streakline density, the first finger print information is position, direction or type of the fingerprint image with respect to central point and streakline density.Wherein, in
Heart point is the central point of fingerprint image, and the corresponding central point of different fingerprint images can be with identical or different.
In addition, for the first finger print information of fingerprint image absolute presupposition feature, it will be understood that be that fingerprint image is corresponding
First finger print information of other one or more global characteristics and/or local feature absolute presupposition features in addition to default feature.
Central point is characterized as example, default, and electronic equipment determines the global characteristics and triangulation point of fingerprint image, ramification point, starting point, end
First finger print information with respect to central point such as point, binding site, dot, ommatidium, spillikin, small hook, foot bridge.
It should be appreciated that the term "and/or" used in the disclosure is only a kind of incidence relation for describing affiliated partner, table
Show there may be three kinds of relations.For example, global characteristics and/or local feature, can be represented：Individualism global characteristics, simultaneously
There are global characteristics and local feature, these three situations of individualism local feature.
Explanation for each term in above-mentioned global characteristics and local feature refers to GA 774《Fingerprint characteristic specification》, this
Place is repeated no more.
In step 103, the first finger print information is matched with having preserved finger print information.
The first finger print information is searched in finger print information has been preserved, matching result is obtained.
At step 104, according to matching result, it is determined whether preserve the first finger print information.
The step can be accomplished in several ways.Refer to for example, matching result is contained in have preserved for the first finger print information
Line information, then do not preserve first finger print information.
In summary, the fingerprint input method that the present embodiment is provided, it is determined that the fingerprint image absolute presupposition of current typing is special
The first finger print information for levying, by the way that the first finger print information is determined whether into preservation first with having preserved finger print information and having been matched
Finger print information, to exclude the typing of identical fingerprints information.
In the above-described embodiments, determined whether to preserve the first finger print information according to matching result, can included：If matching knot
It is empty that fruit, which is the first finger print information and has preserved the common factor of finger print information, then preserves the first finger print information；If matching result is the
One finger print information is not sky with the common factor for having preserved finger print information, and common factor information matches fail, then do not preserve the first fingerprint letter
Breath；If it is not empty that matching result, which is the first finger print information and has preserved the common factor of finger print information, and common factor information matches are successful, then
Preserve the first finger print information.
Wherein, the first finger print information is sky with having preserved the common factor of finger print information, illustrates that the two does not include identical information,
It is appreciated that the fingerprint image of current typing is in non-typing before, therefore preserve the first finger print information；First finger print information with
The common factor for preserving finger print information is not sky, illustrates the first finger print information and preserved finger print information there is identical part, for example,
First finger print information, which is contained in, has preserved finger print information, then the first finger print information refers to having preserved the common factor of finger print information for first
Line information, namely occur simultaneously not for sky.
It is not space-time in the first finger print information and the common factor for having preserved finger print information, determines whether the common factor information of the two
It is whether identical.For example, position of first finger print information with respect to position its central point relative with having preserved finger print information of its central point
Put identical, i.e., the common factor of the two is not sky, now common factor information is the central point of the two, then determines whether the central point of the two
It is whether identical；If the central point of the first finger print information is identical with the central point for having preserved finger print information, the match is successful；If first
The central point of finger print information is different from the central point for having preserved finger print information, then it fails to match.
