It is a variety of that mobile terminal detects that the mode of the moving operation of the finger can have, and can shielded according to the finger Whether the projected position on curtain changes to judge whether finger moves, can also be according between the finger and the screen Vertical range value judge whether finger moves, can also be according to the finger and the most low coverage of whole fingerprint pickup areas From judging whether the finger is moved.

Mobile terminal determined in the fingerprint collecting region, the tool with shortest second target area of distance of the finger Body implementation process, may refer to determine the specific implementation process in first object region in above-mentioned steps 201, repeats no more.

Absolute distance value between step 205, the acquisition finger and second target area.

After mobile terminal determines the second target area nearest with finger current distance according to above-mentioned steps 204, institute is obtained State the absolute distance value between finger and second target area.Calculate absolute between finger and second target area The specific implementation process of distance value, may refer to obtain in above-mentioned steps 202 between the finger and second target area Absolute distance value specific implementation process, repeat no more.

If the absolute distance value between step 206, the finger and second target area is less than or equal to described First threshold, fingerprint icon is lighted in second target area.

After absolute distance between finger described in acquisition for mobile terminal and second target area, judge the finger with Whether the absolute distance value between second target area is less than or equal to first threshold, is less than in judgement absolute distance value Or equal to first threshold after, light fingerprint icon in second target area.

On the basis of above-described embodiment, the mobile terminal lights fingerprint image timestamp in second target area, can To extinguish the fingerprint icon lighted in the first object region, so that user knows the nearest fingerprint collecting after movement in time Region.Mobile terminal after the moving operation of finger is monitored, can determine fingerprint immediately with the state of the finger on monitoring screen The region nearest with finger in pickup area, as new target area, and is judging the absolute of finger and new target area When distance value is less than or equal to first threshold, fingerprint icon is lighted in new target area.Mobile terminal real-time update is lighted Fingerprint icon, so that the fingerprint icon is presented with the mobile and mobile scene of the finger of user, facilitates user to know at any time Nearest fingerprint collecting region, and add interesting display effect when finger moves.

On the basis of above-described embodiment, the implementation process of step 204 and thereafter step can also be according to detection user's hand Refer to the reference frame difference of moving operation and change.If mobile terminal using finger projection on the screen as user's finger whether Two kinds of embodiments, can occur in mobile basis for estimation.

One is mobile terminal detects that the view field of finger on the screen changes, then can be according to step 204 To the specific implementation process of step 206, calculate and the second closest target area of finger, acquisition finger and the second target area The absolute distance value in domain, fingerprint icon is lighted when absolute distance value is less than or equal to first threshold in the second target area, Realize real time monitoring finger, and light the fingerprint icon in nearest fingerprint collecting region in real time.

The second is mobile terminal detects that the view field of finger on the screen does not change, then can be by described first Target area controls the fingerprint icon in the first object region still as the fingerprint collecting region nearest apart from the finger In lasting illuminating state.

It is mobile to improve user experience in order to increase the interest that fingerprint icon is shown on the basis of above-described embodiment It is aobvious that terminal can also set fingerprint image target display parameters to change with the change of the vertical range value between finger and screen Show effect, the change of display effect can specifically be shown as to increase or the decrease of fingerprint image target display parameters, fingerprint image Target display parameters can be fingerprint image target display brightness and display area size.

In a kind of embodiment, mobile terminal can control the fingerprint image target of second target area to show Parameter weakens with the increase of the vertical range value, and when as user's finger is away from screen, fingerprint image target display brightness becomes Small, display area diminishes so that fingerprint icon refers to the operation to frame out and the dimmed effect to diminish is presented conveniently.In mobile terminal Second threshold can also be set, or still using first threshold as Rule of judgment, in the finger to second target area When the distance between domain increases to default second threshold or first threshold, extinguish fingerprint icon, to reduce power consumption.

Mobile terminal can also control the fingerprint image target display parameters of second target area with the vertical range The reduction of value and strengthen, be user's finger close to screen when, fingerprint image target display brightness becomes larger, and display area becomes larger, and makes Fingerprint icon presents the effect that brightens of becoming larger is presented close to action with finger, similar to by the effect of finger inspiration screen, into The interest that one step enhancing fingerprint icon is shown.

Above-mentioned control fingerprint icon refers to the scheme for changing and changing with the vertical range value of screen conveniently, can be answered with limited For finger on the screen view field do not change vertical range value change when situation.Mobile terminal can sentenced Cut off the hands and refer to view field when not changing, only pass through the change fingerprint image according to the vertical range between finger and screen The display effect of gradual change is presented in mark, reduces the calculation procedure of mobile terminal, and improve user experience.

The fingerprint image target display methods that the embodiments of the present invention provide, it is corresponding with fingerprint module by obtaining finger The distance between fingerprint collecting region is worth, and when judging that distance value is less than default first threshold, just lights fingerprint icon, with Just user knows the specific location in fingerprint collecting region.In this way, mobile terminal can be user light display fingerprint icon and The technical problem of fingerprint icon increase screen locking power consumption is persistently lighted in solution.When mobile terminal detects finger movement, upgrade in time Show the fingerprint icon in nearest fingerprint collecting region, facilitate user to know nearest fingerprint collecting region at any time, and add Interest and display effect when finger moves.The specific implementation of fingerprint image target display methods provided in an embodiment of the present invention Journey, reference can be made to the specific implementation process for the fingerprint collecting method that the embodiment shown in above-mentioned Fig. 1 provides, no longer goes to live in the household of one's in-laws on getting married one by one herein State.

Fig. 3 is referred to, Fig. 3 is the flow signal of another fingerprint image target display methods provided in an embodiment of the present invention Figure, the fingerprint image that fingerprint image target display methods provided in an embodiment of the present invention is provided with the embodiment shown in above-mentioned Fig. 1 and Fig. 2 Target display methods difference lies in:Add and fingerprint authentication is judged whether to according to the magnitude relationship of pressure value and the 3rd threshold value Operation.As shown in figure 3, a kind of fingerprint image target display methods, comprises the following steps:

Step 301, in the state of the screen locking of mobile terminal, obtain finger to the corresponding fingerprint collecting of fingerprint module The distance between region is worth.

Mobile terminal is in the state of screen locking, when sensing finger, obtain the finger to fingerprint collecting region it Between distance.The specific implementation process in the distance between finger and the fingerprint collecting region is obtained, may refer to above-mentioned steps 101 and the specific implementation process of step 202, repeat no more.

If step 302, the finger be less than to the distance between the corresponding fingerprint collecting region of fingerprint module value or Person is equal to first threshold, and fingerprint image mark is lighted in the fingerprint collecting region.

Mobile terminal judges that the finger to the distance between fingerprint collecting region value is less than or equal to the first threshold After value, fingerprint image mark is lighted in the fingerprint collecting region, its specific implementation process may refer to above-mentioned steps 102 and step 203 specific implementation process, repeats no more.

Step 303, obtain the pressure value that the finger acts on the fingerprint collecting region.

After mobile terminal lights fingerprint image mark in fingerprint collecting region, the corresponding fingerprint of fingerprint icon is touched for user's finger Pickup area, so as to the corresponding fingerprint module collection finger print data in the fingerprint collecting region.In view of user in the action such as running In, it is understood that there may be finger touches unintentionally the operation of screen.User is not intended to carry out fingerprint authentication removing screen locking at this time, If the finger print data of mobile terminal collection at this time is unlocked, in fact it could happen that misreads the situation of lock, or even user occurs unintentionally The continuous faulty operation at the interface after removing screen locking etc. is clicked on, the normal use to user impacts.

Therefore, mobile terminal can be the operation for carrying out fingerprint authentication according to the size discrimination user of pressure value, or by mistake The touch operation of mobile terminal is touched, mobile terminal collection user's finger acts on the pressure value in fingerprint collecting region.

If step 304, the pressure value are more than or equal to the 3rd threshold value, the fingerprint number of the fingerprint module collection is verified According to.

The 3rd threshold value is preset in mobile terminal, the 3rd threshold value and the finger gathered are acted on into fingerprint collecting region Pressure value be compared.If the pressure value is less than the 3rd threshold value, it may infer that user simply touches screen, do not expect Fingerprint authentication removing screen locking, at this time the fingerprint module of mobile terminal do not gather the finger print data of the finger.If the pressure Force value is more than or equal to the 3rd threshold value, then may infer that user expects fingerprint authentication removing screen locking, at this time mobile terminal Fingerprint module gather the finger print data of the finger.Mobile terminal is by acquired finger print data, with the advance typing of user Normal data is compared.

If step 305, the finger print data are verified, the screen locking of the mobile terminal is released.
