step 101: a holding position of the mobile terminal is detected.
The mobile terminal screen comprises a plurality of sub-areas. In a specific implementation process, a user can hold the mobile terminal with one hand and can also hold the mobile terminal with two hands. When the screen is held by a single hand, the screen can be held by the left hand or the right hand, different holding modes correspond to different holding positions, and the specific screen subareas which can be clicked and operated at different holding positions are different.

step 201: a holding position of the mobile terminal is detected.
The screen of the mobile terminal comprises a plurality of screen subregions, and the screen subregions are combined to form a screen. The number of partitions and the partition rule of the screen sub-area may be set by those skilled in the art according to actual requirements, and are not particularly limited in the embodiment of the present invention.
Different holding modes correspond to different holding positions, and the corresponding relation between the different holding positions and the sub-areas on the screen is preset in the mobile terminal.
One preferred setting of the correspondence of the holding position to the sub-area on the screen is as follows:
when the holding mode corresponding to the holding position is left-handed holding, the sub-area corresponding to the holding position is a sub-area at the middle position of the left side of the screen;
when the holding mode corresponding to the holding position is right-hand holding, the sub-area corresponding to the holding position is the sub-area at the middle position of the right side of the screen;
the holding mode corresponding to the holding position is that when two hands hold the screen transversely, the sub-area corresponding to the holding position is the sub-area at the middle position of the left side of the screen and/or the sub-area at the middle position of the right side of the screen;
the holding mode corresponding to the holding position is that when two hands hold the screen vertically, the sub-area corresponding to the holding position is the sub-area at the middle position of the left side of the screen and/or the sub-area at the middle position of the right side of the screen.
Based on the corresponding relation between the preferred holding position and the sub-area in the screen, the determined fingerprint identification area is convenient for the user to operate.
Step 202: and inquiring the sub-area corresponding to the holding position in the corresponding relation according to the holding position.
After the holding position is determined, based on the corresponding relation between the holding position preset by the mobile terminal and the screen sub-area, the sub-area matched with the holding position can be determined.
Step 203: and determining the queried subarea as a fingerprint identification area.

During fingerprint collection, the mobile terminal only collects fingerprints in a fingerprint identification area, and does not collect fingerprints in other screen subareas.
According to the fingerprint identification method provided by the embodiment of the invention, the fingerprint identification area is determined according to the holding position of the mobile terminal, and the fingerprint information is acquired through the fingerprint identification area, so that the false touch rate of fingerprint identification is reduced, and the success rate of fingerprint identification is improved. The use experience of the user can be improved.
EXAMPLE III
Referring to fig. 3, a flowchart illustrating steps of a fingerprint identification method according to a third embodiment of the present invention is shown.
In the embodiment of the present invention, an example of determining a fingerprint identification area by combining a holding position of a mobile terminal and fingerprint identification parameters corresponding to sub-areas in a screen is described, where the fingerprint identification method in the embodiment of the present invention specifically includes the following steps:
step 301: a holding position of the mobile terminal is detected.
The screen of the mobile terminal comprises a plurality of screen subregions, and the screen subregions are combined to form a screen. The number of partitions and the partition rule of the screen sub-area may be set by those skilled in the art according to actual requirements, and are not particularly limited in the embodiment of the present invention.
Different holding modes correspond to different holding positions, and the first weight values corresponding to the sub-areas in the screen are different. The higher the first weight value is, the more convenient the sub-region is for the user to click.
Step 302: and determining fingerprint identification parameters corresponding to all sub-areas on the screen of the mobile terminal.
Among them, the fingerprint identification parameters include but are not limited to: the method comprises the steps of determining the surface cleanliness of a screen subregion, the dead pixel occupation ratio of a sensor in a sensing region corresponding to the screen subregion, determining whether the sensor is a dead pixel or not through historical reporting signals of the sensor, and marking the dead pixel of the sensor in the mobile terminal in advance.
In the using process of the mobile terminal, whether each sensor is a dead pixel or not can be monitored, the sensor of the dead pixel is marked, and the dead pixel of the sensor can be determined through the later period of the marking. Specifically, in the historical use process, if the mobile terminal determines that a certain screen sub-area is a fingerprint identification area, signals reported by each sensor in the fingerprint identification area are monitored, and if a certain sensor in the area does not upload a signal, it is determined that the sensor is damaged as a dead pixel, so that the sensor is marked.
After the holding position and the fingerprint identification parameters corresponding to the sub-areas of the screen are determined, at least one sub-area can be determined on the screen of the mobile terminal as a fingerprint identification area according to the holding position and the fingerprint identification parameters corresponding to the sub-areas.
A preferred way to determine at least one sub-area as the fingerprint identification area on the screen of the mobile terminal according to the holding position and the fingerprint identification parameters corresponding to each sub-area is as described in steps 303 to 306.
Step 303: and respectively determining a first weight value corresponding to each sub-area according to the holding position.
One preferable way of determining the first weight value corresponding to each sub-region according to the holding position is as follows:
when the holding mode corresponding to the holding position is left-handed holding, the distance between the center point of each subarea and the reference point is determined by taking the center point of the left half part of the screen as the reference point; distributing a first weight value to each subregion according to the corresponding distance of each subregion; wherein, the larger the distance, the smaller the first weight value.
When the holding mode corresponding to the holding position is right-hand holding, the distance between the center point of each sub-area and the reference point is determined by taking the center point of the right half part of the screen as the reference point; distributing a first weight value to each subregion according to the corresponding distance of each subregion; wherein, the larger the distance, the smaller the first weight value.
For example: when the user holds the mobile terminal with the right hand at the middle position of the mobile terminal, the first weight value of the screen subarea at the middle position of the right side of the screen is the highest, and the first weight value of the screen subarea far away from the middle position of the right side of the screen is lower. For example, the first weight value of the screen subregion at the right middle position is set to 10, the first weight value of the screen subregion slightly deviated from the middle position is set to 9, the first weight value of the screen subregion deviated from the middle position is set to 8, and the first weight values of the screen subregions sequentially decrease according to the above rule.
Step 304: and respectively determining a second weight value corresponding to each sub-region according to the fingerprint identification parameters corresponding to each sub-region.
Specifically, for each sub-region, determining the surface cleanliness of the sub-region and the dead pixel ratio of a sensor in a sensing region corresponding to the sub-region; determining a second weighted value corresponding to the sub-region according to the cleanliness and the dead pixel ratio; wherein, the higher the cleanliness is, the smaller the proportion is, the higher the second weighted value is.
For example: if the surface of the first screen subregion on the screen is free of dirt (i.e., the cleanliness is high) and the states of the fingerprint sensors corresponding to the first screen subregion are good (i.e., the sensor dead pixel ratio in the sensing region corresponding to the screen subregion is 0), the second weight value of the first screen subregion is set to be 10 minutes full points, if the state of the fingerprint sensor corresponding to the second screen subregion on the screen is good but the screen surface is dirty, the second weight value of the second screen subregion is set to be 9 minutes, and the surface of the third screen subregion on the screen is free of dirt, but some dead pixels (i.e., the sensor is damaged) in the sensing region corresponding to the screen subregion may affect fingerprint image acquisition, and the second weight value of the third screen subregion is set to be 8. If there is dirt on the surface of the fourth screen subregion on the screen and there are many dead spots in the sensing region corresponding to the screen subregion, the second weight value of the fourth screen subregion may be set to 1, and so on. The higher the second weight value of the screen subarea is, the higher the fingerprint identification rate of the screen subarea is represented.
Step 305: and for each sub-region, determining a target weight value corresponding to the sub-region according to the first weight value and the second weight value corresponding to the sub-region.
When the target weight value corresponding to each screen sub-region is determined, the first weight value and the second weight value corresponding to the screen sub-regions may be weighted and then summed.
For example: and if the first weight value corresponding to a certain screen subregion is A, the second weight value is B, the weight coefficient corresponding to the first weight value is a, and the weight coefficient corresponding to the second weight value is B, the target weight value C corresponding to the screen subregion is C ═ A + B ×.
The larger the C value is, the more convenient the screen subarea is for touch identification and the higher the fingerprint identification rate is.
Step 306: and sequencing the target weight values from large to small, determining sub-areas corresponding to the target weight values in the preset number in the front sequence as fingerprint identification areas, and highlighting the fingerprint identification areas on a screen.
The preset number may be one or more, and in a specific implementation process, a specific numerical value of the preset number may be set in advance by a person skilled in the art or by a mobile terminal user.
Step 303 to step 306 are a preferable manner of determining at least one sub-area on the screen of the mobile terminal as the fingerprint identification area according to the holding position and the fingerprint identification parameter corresponding to each sub-area, and in a specific implementation process, the method is not limited to the manner shown in step 303 to step 306, and the fingerprint identification area may also be determined in the following manner:
firstly, determining a first sub-area from a mobile terminal screen according to a holding position;
when the first sub-area is determined from the screen of the mobile terminal according to the holding position, the first sub-area can be determined according to the corresponding relation between the holding position stored in the mobile terminal in advance and the sub-area on the screen. For the specific correspondence between the holding position and the sub-area on the screen, reference may be made to the relevant description in the second embodiment, which is not specifically limited in the embodiment of the present invention.
Secondly, determining whether the fingerprint identification rate of the sub-area is greater than a preset value or not according to the fingerprint identification parameters corresponding to the first sub-area for each first sub-area; and if so, determining the first sub-area as a fingerprint identification area.
When the fingerprint identification rate of the first sub-area is determined, a second weight value corresponding to each first sub-area may be calculated in the manner shown in step 304, the fingerprint identification rate of the first sub-area is represented by the second weight value, and when the second weight value is greater than a preset value, it is determined that the fingerprint identification rate of the first sub-area is greater than the preset value.
In the specific implementation process, the preset value may be set by a person skilled in the art according to actual requirements, which is not specifically limited in the embodiment of the present invention. For example: set to values of 5, 6, 8, etc.
Step 307: fingerprint information is collected through the fingerprint identification area, and the fingerprint information is matched.
After the fingerprint identification area is highlighted on the screen, a user can visually see the fingerprint identification area according to a prompt, and the displayed fingerprint identification area can be directly pressed by a finger when fingerprint authentication is needed. During fingerprint collection, the mobile terminal only collects fingerprints in a fingerprint identification area, and does not collect fingerprints in other screen subareas.
