Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of finger print navigation methods, applied to the generation including finger print navigation signal
The fingerprint recognition mould group of device, the process of finger print navigation method is as shown in Figure 1, specific as follows in the present embodiment:
In a step 101, whether detection finger presses.If then entering step 102, otherwise terminate process.Specifically,
In present embodiment, can have been detected whether by the depression detection module in the generation device of finger print navigation signal finger by
Pressure；When depression detection module detects finger pressing, interruption can be generated；At this point, the generation device of finger print navigation signal enters
Navigation detects, and the finger print detecting module in the generation device of finger print navigation signal, which enters working condition, (can acquire fingerprint image
Picture).It will be appreciated, however, that present embodiment is not intended to be limited in any the concrete mode for judging whether finger presses.
In a step 102, one group of fingerprint image is obtained.Specifically, the generation device of finger print navigation signal can be passed through
In finger print detecting module obtain fingerprint image, one group of fingerprint image in present embodiment may include a fingerprint image,
It also may include multiple fingerprint images.In practical applications, fingerprint identification module acquires fingerprint image always with default frequency acquisition
Picture.Every group of fingerprint image can be set as collected fingerprint image within a preset period of time；Such as default frequency acquisition is
100 milliseconds, preset time period is 1 second, then every group of fingerprint image includes 10 fingerprint images.Alternatively, every group of fingerprint image
It can be set as the fingerprint image of preset number；Such as preset number 5, i.e. every group of fingerprint image include 5 fingerprint images
(if default frequency acquisition is 100 milliseconds, is the equal of the fingerprint image acquired in 0.5 second).
Wherein, the number of fingerprint image is fewer in every group of fingerprint image, indicates that the refresh rate of finger print navigation is higher.
In step 103, according to preset navigational parameter and this group of fingerprint image, accumulation calculating finger works as front slide position
It moves.Specifically, the navigational parameter in present embodiment includes navigation mode and benchmark glide direction, which is folk prescription
To sliding-modes.The navigation mode can be by determining in current application program, that is, can preset in each application program
Its corresponding navigation mode.In addition, mark reference of reference glide direction is also provided in the generation device of finger print navigation signal,
Benchmark glide direction can may be user preset for factory preset.
In present embodiment, current slide displacement can be the displacement accumulated value in benchmark glide direction.According to finger
Print image calculate finger in the slide displacement in reference direction, can be calculated using coordinate method, specifically, can select
Fixed several fingerprint feature points, export the origin coordinates (X0 of each characteristic point1, Y01)~(X0n, Y0n)；Then it extracts and to have selected
Subsequent terminating coordinates (the X of fingerprint feature point1, Y1)~(Xn, Yn)；Terminating coordinates are compared with origin coordinates, obtain coordinate
Matrix of differences (Δ X1, Δ Y1)~(Δ Xn, Δ Yn)；According to the positive and negative and order of magnitude of coordinate matrix of differences as judgement item
Part carries out the identification of direction of fingerprint, and calculates the displacement for identifying fingerprint movement.Certainly, in practical applications, can also use
The slide displacement in reference direction of other methods calculating finger.
At step 104, judge whether current slide displacement meets preset condition.If then entering step 105, otherwise into
Enter step 106.Specifically, the preset condition in present embodiment can be configured in terminal system, such as, this is pre-
If condition can include N times (N is natural number) of preset displacement for current slide displacement, the occurrence of the preset displacement can be
It is set in system.Wherein, the initial value of N is 1, if judging, current slide displacement meets preset condition, N cumulative 1；If judgement
Current slide displacement is unsatisfactory for preset condition out, then N is constant.
In step 105, finger print navigation signal is generated.Specifically, which can be for for operating various answer
With the control signal of program, such as, the control signal of control navigation terminal page turning, video fast forward or volume adjustment etc..?
In practical application, when current slide displacement is equal to N times (N is natural number) of preset displacement, a finger print navigation signal is generated,
The current slide displacement that adds up is then proceeded to, when current slide displacement is equal to N+1 times (N is natural number) of preset displacement, further
One finger print navigation signal of secondary generation.
As above, step 102 to step 105 may be considered primary navigation detection.
In step 106, whether detection finger discharges.If then terminating process, otherwise return step 102.Specifically,
In present embodiment, it can detect whether finger discharges by the depression detection module in the generation device of finger print navigation signal；
When fingerprint identification module detects finger release, interruption can be generated；At this point, finger print detecting module stops Image Acquisition work；
When depression detection module detection finger does not discharge, return step 102 enters navigation detection next time.Present embodiment pair
The concrete mode for judging whether finger discharges is not intended to be limited in any.
By the above-mentioned description to step it is found that as long as finger does not discharge, so that it may which circulation executes navigation detection, as long as i.e. hand
Refer to and be in pressing state, lasting navigation can be realized.
It is illustrated so that navigation mode is one direction sliding-modes as an example below, wherein one direction sliding-modes refer to only
The slide displacement on a direction is detected, which is the benchmark glide direction set.Benchmark glide direction can be
Direction may be horizontal left direction horizontally to the right, by taking benchmark glide direction is horizontal direction right as an example: sensing hand
After referring to pressing, meeting continuous acquisition fingerprint image (or fingerprint image of acquisition preset number) within one section of preset time period
As one group of fingerprint image.Pass through fingerprint image different in contrast groups, it can be determined that the glide direction of finger.Fig. 2 is application
A kind of possible finger sliding trace in fingerprint recognition mould group.As shown in Fig. 2, finger is successively according to arrow S1, S2, S3, S4
Direction alternately to right and left slide.
Using the glide direction of horizontal direction right as benchmark direction, the slide displacement only to add up horizontally to the right, or cumulative point
Slide displacement in solution to direction horizontally to the right, finger just slide to the right according to arrow S1 after contacting fingerprint recognition mould group.
In sliding process later, all displacements to the right or the displacement decomposed to the right can be accumulated, opposite with reference direction
Displacement (displacement to the left) can be ignored, and final accumulation displacement should be S1+S3.Cumulative when sliding is displaced to preset condition
When, a navigation signal (for example turning over one page) is exported, when the cumulative displacement of sliding reaches preset condition again, is exported another
A navigation signal (such as page turning again), this cumulative strategy can be used for dragging applied field as scroll bar and continuous page turning
Scape.
When dragging scroll bar, the only displacement in the cumulative glide direction obtained before.If finger is in fingerprint in this way
It constantly slidably reciprocates in identification mould group, slides to the right at the beginning, scroll bar can be to scrolling right therewith.Then finger is not lifted
It rises, is changed to slide to the left, scroll bar does not do and reacts at this time.When finger slides to the right again, scroll bar can be again with to downslide
It is dynamic.That is, direction at the beginning is slided in scroll bar meeting " remembeing " every time.As long as finger does not lift, on other directions
Displacement can be ignored, and the displacement on the direction of " being remembered " can be cumulatively added, and reflect onto the rolling distance of scroll bar.Fig. 3 column
Accumulation displacement is gone out and actual displacement respectively changes with time.Horizontal axis indicates the time in figure, and the longitudinal axis indicates displacement, 31 tables
Show accumulative displacement, 32 indicate actual displacement.
Compared with the existing technology, during finger presses navigation device, circulation executes navigation detection, by by cumulative finger
Slide displacement generate a finger print navigation signal in a slide displacement preset condition of every satisfaction, can be pressed in finger

Specifically, the navigational parameter in present embodiment includes navigation mode and benchmark glide direction, wherein the mould that navigates
Formula is twocouese sliding-modes, and it is anti-with benchmark glide direction that the current slide displacement in present embodiment is benchmark glide direction
Displacement accumulated value on direction.For example, benchmark glide direction is that horizontally to the right, then the opposite direction of benchmark glide direction is horizontal direction
It is left.
Still for being displaced described in Fig. 2, under this policy, the displacement of both direction can be all cumulatively added.Most
The displacement accumulated eventually should be S1+S2+S3+S4.This cumulative strategy can be used for adjusting video progress, adjust volume, be continuous
The application scenarios such as page turning.
If this function for adjusting video progress, can add up horizontally to the right with the position in horizontal both direction to the left
It moves.In this way, when finger slidably reciprocates in left-right direction, video progress can accurately retreat or preceding according to the specific displacement of sliding
Enter the position that user specifies.Cumulative displacement and actual displacement under this strategy change with time as shown in figure 4,41 in figure
Indicate accumulative displacement, 42 indicate actual displacement.
When continuous page turning, can also add up the displacement with horizontal both direction to the left horizontally to the right, such as, it can be with
The displacement of prescribed level to the right is positive displacement, then horizontal displacement to the left is negative displacement.Once the absolute value of accumulation displacement reaches
Predetermined value just sends a page turning signal (i.e. finger print navigation signal), and the direction of page turning is that the symbol that accumulation is displaced is corresponding
Direction.If accumulation shift value is positive, glide direction is represented as horizontally to the right, operating handset page turning backward at this time；If accumulation
Shift value is negative, represent glide direction as it is horizontal to the left, then operating handset Page forward.
In present embodiment, a kind of twocouese sliding-modes are provided, accumulation calculating finger slides up in two opposite sides
