Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In some embodiments of the present invention, a scanning method for fingerprint identification is provided, which is applied to a mobile terminal, where a fingerprint identification sensor is disposed below a touch screen of the mobile terminal.
Here, make fingerprint identification sensor and mobile terminal touch-sensitive screen as an organic whole, can realize the purpose of full-screen fingerprint unblock through scanning whole touch-sensitive screen, and any area of touch-sensitive screen is touched to the user finger this moment, can both be detected its fingerprint characteristic by fingerprint identification sensor, and then carries out the screen unblock.
Referring to fig. 1, the method includes:
Here, the touch screen is divided into one or more fingerprint identification areas in advance, and the scanning frequencies corresponding to different fingerprint identification areas may be the same or different. In the step, the scanning frequency corresponding to each fingerprint identification area is obtained, so that the subsequent beam scanning in areas is facilitated.
And 102, controlling the fingerprint identification sensor to perform fingerprint identification scanning on each fingerprint identification area according to the scanning frequency corresponding to each fingerprint identification area.
Here, by controlling the fingerprint identification sensor to perform fingerprint identification scanning on each fingerprint identification area according to the scanning frequency corresponding to each fingerprint identification area, the fingerprint identification scanning on the touch screen in different areas is realized, and different scanning frequencies can be used on each area. For example, for a fingerprint identification area frequently used by a user, the scanning frequency of the fingerprint identification sensor can be properly increased, namely, a higher scanning frequency is used, and for a fingerprint identification area not frequently used by the user, the scanning frequency of the fingerprint identification sensor can be properly reduced, namely, a lower scanning frequency is used. The whole touch screen does not need to use higher frequency, and the power consumption is reduced. And the split area scanning increases the unlocking speed.
Wherein, the scanning process of each fingerprint identification area can be carried out in parallel.
According to the fingerprint identification scanning method, the fingerprint identification scanning is carried out on the touch screen in different areas, the scanning area of each area is reduced relative to the area of the whole touch screen, so that the scanning speed is increased, the unlocking speed is increased, the fingerprint identification scanning can be carried out on each area by respectively using different scanning frequencies through distinguishing treatment on each fingerprint identification area on the touch screen, the whole touch screen is not required to be rapidly scanned by using higher frequencies, the power consumption is reduced, and the electric quantity is saved.
Optionally, as shown in fig. 2, the step 101 includes:
Here, the preset usage level of each fingerprint identification area on the touch screen is pre-established, so that the scanning frequency corresponding to each area is determined according to the preset usage level.
Specifically, the step 1011 includes:
step 10111, obtaining the use frequency information corresponding to each fingerprint identification area on the touch screen.
Here, the preset usage level of each area is determined according to the usage frequency information by acquiring the usage frequency information corresponding to each fingerprint identification area on the touch screen.
Wherein, the usage frequency represents the frequency of fingerprint identification of the user in the fingerprint identification area.
The touch information of the touch operation on the touch screen can be counted in advance, and then the use frequency information of each fingerprint identification area is obtained in a big data analysis mode. Therefore, the fingerprint identification areas frequently used by the user and the fingerprint identification areas not frequently used by the user can be automatically learned for distinguishing treatment.
Step 10112, determining the preset usage level corresponding to each fingerprint identification area according to the usage frequency information corresponding to each fingerprint identification area.
Here, according to the usage frequency information corresponding to each fingerprint identification area, the preset usage level corresponding to each fingerprint identification area can be accurately and reasonably determined.
The preset use level corresponding to each fingerprint identification area can be determined according to the rule that the preset use level corresponding to the fingerprint identification area with higher use frequency is higher and the use frequency information corresponding to each fingerprint identification area. That is, the preset usage level is higher for the area where the user performs fingerprint recognition frequently, and conversely, the preset usage level is lower for the area where the user performs fingerprint recognition frequently.
Here, according to the preset usage level corresponding to each fingerprint identification area, the scanning frequency corresponding to each area can be accurately and reasonably determined.
The scanning frequency corresponding to each fingerprint identification area can be determined according to the rule that the scanning frequency corresponding to the fingerprint identification area with the higher preset use level is higher and the preset use level corresponding to each fingerprint identification area is higher. That is, the higher the preset usage level, i.e., the higher the frequency of user fingerprint recognition, the higher the scanning frequency, and conversely, the lower the preset usage level, i.e., the lower the frequency of user fingerprint recognition, the lower the scanning frequency.
For example, as shown in fig. 3, the touch screen includes two fingerprint identification areas, and the frequency of use of the fingerprint identification area a is a1 and the frequency of use of the fingerprint identification area B is B1, where a1 is greater than B1, that is, the frequency of fingerprint identification performed by the user in the fingerprint identification area a is greater than the frequency of fingerprint identification performed in the fingerprint identification area B. Then, the preset usage levels corresponding to the fingerprint identification areas a and B may be determined according to the usage frequencies corresponding to the fingerprint identification areas a and B, respectively, for example, the preset usage level corresponding to the fingerprint identification area a may be determined as a first level, and the preset usage level corresponding to the fingerprint identification area B may be determined as a second level. Then, according to the preset usage levels corresponding to the fingerprint identification areas a and B, determining the respective corresponding scanning frequencies, for example, determining that the scanning frequency corresponding to the fingerprint identification area a is f1, and the scanning frequency corresponding to the fingerprint identification area B is f2, where f1 is greater than f2, that is, for an area with a higher preset usage level, that is, a higher frequency of fingerprint identification performed by the user, a higher scanning frequency is used, and for an area with a lower preset usage level, that is, a lower frequency of fingerprint identification performed by the user, a lower scanning frequency is used. Therefore, the whole touch screen does not need to be scanned at a higher frequency, and the power consumption is reduced. And the split area scanning increases the unlocking speed.
For another example, as shown in fig. 4, the touch screen includes four fingerprint identification areas, and the frequency of obtaining the fingerprint identification areas 1, 2, 3, and 4 is sequentially reduced by counting the touch information of the touch operation on the touch screen. Then, the preset usage levels corresponding to the fingerprint identification areas 1, 2, 3, and 4 can be determined according to the usage frequencies corresponding to the fingerprint identification areas 1, 2, 3, and 4, respectively, and if it is determined that the preset usage level corresponding to the fingerprint identification area 1 is the first level, the preset usage level corresponding to the fingerprint identification area 2 is the second level, the preset usage level corresponding to the fingerprint identification area 3 is the third level, and the preset usage level corresponding to the fingerprint identification area 4 is the fourth level. Therefore, the scanning frequency corresponding to the fingerprint identification area 1 is the highest, the scanning frequency corresponding to the fingerprint identification area 2 is the second time, and the like, and the scanning frequency corresponding to the fingerprint identification area 4 is the lowest. Therefore, the most frequently used area scanning frequency is the highest, and the least frequently used area scanning frequency is the lowest, so that the unlocking speed can be maximally improved, and meanwhile, the power consumption of the fingerprint module is maximally reduced.
Optionally, the method further comprises:
step 103, when detecting the touch operation in the fingerprint identification area, updating the use frequency information of the fingerprint identification area corresponding to the touch operation.
At the moment, when the touch operation in the fingerprint identification area is detected, the use frequency information of the fingerprint identification area is updated, then the preset use level of each fingerprint identification area can be determined again according to the updated use frequency information, and then the scanning frequency of each fingerprint identification area is adjusted according to the re-determined preset use level, so that the scanning frequency of each fingerprint identification area can be continuously optimized in a dynamic adjustment mode, the unlocking speed of full-screen fingerprint unlocking is improved to the maximum extent, the power consumption is reduced to the maximum extent, and the power consumption of the whole machine is reduced to the minimum extent while the full-screen fingerprint identification performance is improved.
Optionally, after the step 102, the method further includes:
and 104, acquiring fingerprint information acquired by the fingerprint identification sensor when the touch operation in the fingerprint identification area is detected.
Here, by controlling the fingerprint recognition sensor to perform fingerprint recognition scanning on each fingerprint recognition area, when a touch operation in any one area is detected, fingerprint information can be acquired, so that screen unlocking can be performed based on the fingerprint information.
And 105, unlocking the screen of the mobile terminal when the fingerprint information is matched with the pre-stored fingerprint information.
Here, by comparing the fingerprint information with the pre-stored fingerprint information, when the fingerprint information matches the pre-stored fingerprint information, the screen of the mobile terminal is unlocked, and a fingerprint unlocking function is realized.
The full-screen fingerprint unlocking function needs to quickly scan the whole touch screen to achieve the purpose of full-screen unlocking, so that the speed is low, and the power consumption is relatively high. However, it is found that it is not necessary to perform high-frequency fast fingerprint identification scanning on the whole touch screen, because the commonly used fingerprint unlocking area of the user only occupies a small part of the touch screen, if the high-frequency fast fingerprint identification scanning is performed on all areas of the whole touch screen, the whole machine power is wasted, great power consumption is caused, and the unlocking speed is reduced. According to the fingerprint identification scanning method, the fingerprint identification scanning is carried out on the touch screen in different areas, the scanning area of each area is reduced relative to the area of the whole touch screen, so that the scanning speed is increased, the unlocking speed is increased, the fingerprint identification scanning can be carried out on each area by respectively using different scanning frequencies through distinguishing treatment on each fingerprint identification area on the touch screen, the whole touch screen is not required to be rapidly scanned by using higher frequencies, the power consumption is reduced, and the electric quantity is saved. And the scanning frequency of each area can be dynamically adjusted according to the user operation, so that the balance of user experience optimization and power consumption optimization is achieved.
