In the related technology, when a finger of a user presses an effective area of a fingerprint under a screen, a fingerprint identification process can be awakened; however, in the related art, the screen displays the fingerprint bright spots based on the default brightness values, but the fixed brightness values are not suitable for all fingerprint identification scenes due to the diversity of environments where the terminal is located, for example, when the terminal is in a dark environment, a finger cannot accurately press an effective area of the fingerprint under the screen, so that the bright spots cannot be completely shielded by the finger, highlight light leakage is caused, short-term influence is caused on the vision of a user due to the highlight light leakage, for example, the eye prick or the vision residual bright spots and the like are caused, and the comfort level of the user is reduced; for another example, when the terminal is in a highlight environment, the user may not see the pressing area prompted by the terminal clearly, fingerprint identification efficiency is low, great inconvenience is brought to the user, and user experience is affected.
In order to solve the above problem, an embodiment of the present disclosure provides a fingerprint identification method, which may be applied to a terminal provided with an off-screen fingerprint sensor below a screen, and the method includes the following steps: when the pressing operation of a screen of the terminal is detected, acquiring the ambient light brightness of the environment where the terminal is located; determining the fingerprint bright spot brightness of the screen according to the ambient light brightness and a first mapping relation between the pre-acquired ambient light brightness and the fingerprint bright spot brightness; controlling the screen to display the fingerprint bright spots by using the fingerprint bright spot brightness; and calling the fingerprint sensor under the screen to identify the user fingerprint corresponding to the pressing operation. According to the technical scheme, the environment brightness of the environment where the terminal is located is obtained, and the fingerprint bright spot brightness of the screen is dynamically determined according to the environment brightness, so that the fingerprint bright spot brightness can dynamically adapt to the diversity of the environment where the terminal is located, the problems of high brightness leakage and low fingerprint identification efficiency caused by the adoption of fixed brightness values in the related technology are avoided, the comfort level of a user can be improved, the use of the user is facilitated, and the user experience is improved.
It should be noted that the terminal according to the technical solution may include, for example, an electronic device such as a smart phone, a tablet computer, a notebook computer, or a wearable device (e.g., a bracelet).
Fig. 1 is a flowchart illustrating a fingerprint identification method according to an exemplary embodiment, where an executing subject of the method may be a terminal, and the method is applied to a terminal that is provided with an off-screen fingerprint sensor below a screen, as shown in fig. 1, the method includes the following steps 101 and 104:
in step 101, when a pressing operation on a screen of a terminal is detected, an ambient light level of an environment in which the terminal is located is acquired.
For example, when the user needs to use the terminal and the terminal is in a screen locking state, the user presses a preset fingerprint area of the screen with a finger. When the terminal detects the pressing operation of the screen of the terminal, the ambient light brightness of the environment where the terminal is located is obtained. For example, when the terminal detects a pressing operation of a user on a preset fingerprint area of a screen by means of the screen and/or a pressure sensor, the terminal calls an ambient light sensor of the terminal to measure and obtain ambient light brightness of an environment where the terminal is located; for example, the screen and/or pressure sensor determines whether the finger is pressed within a preset fingerprint area: if the finger is pressed in the preset fingerprint area, an ambient light sensor of the terminal is called to measure ambient light, and a host, a screen and a fingerprint sensor under the screen of the terminal are awakened; if the finger is not pressed in the preset fingerprint area, the terminal is continuously in the screen locking state, and the fingerprint identification process cannot be triggered.
In step 102, the fingerprint hot spot brightness of the screen is determined according to the ambient light brightness and a first mapping relation between the pre-acquired ambient light brightness and the fingerprint hot spot brightness.
For example, after the fingerprint identification process is awakened, the screen may light a lighting area located in the preset fingerprint area, where the lighting area is a fingerprint hot spot, and the fingerprint hot spot brightness is the brightness of the lighting area of the screen.
Illustratively, the terminal obtains a first mapping relationship between the ambient light brightness and the fingerprint hot spot brightness in advance, wherein in the first mapping relationship, different fingerprint hot spot brightness corresponding to different ambient light brightness respectively is recorded. After the terminal obtains the ambient light brightness of the environment, the fingerprint bright spot brightness corresponding to the ambient light brightness can be determined by inquiring the first mapping relation.
Optionally, in the first mapping relationship, the greater the ambient light brightness is, the greater the brightness of the mapped fingerprint bright spots is, so that when the ambient light is strong, the exposure time is reduced, and the brightness of the bright spots is improved to prompt a pressing position, thereby facilitating the fingerprint resolution of a user; when the ambient light brightness is reduced, the mapped exposure time is prolonged, and the brightness of the fingerprint bright spots is reduced, so that when the ambient light is weak, the exposure time is prolonged, the brightness of the bright spots is reduced, the short-term influence of light leakage on the eyesight is reduced, and the comfort of a user is improved.
Illustratively, when a pressing operation for a screen of the terminal is detected, a pressure value of the pressing operation is acquired; when the pressure value is larger than a preset pressure threshold value, acquiring the ambient light brightness of the environment where the terminal is located; the preset pressure threshold is a preset critical value used for triggering the terminal to acquire the ambient light brightness of the environment where the terminal is located. Through setting up the pressure threshold value of predetermineeing and judging the big or small relation of pressure value and predetermineeing the pressure threshold value, only can measure the ambient light brightness of the environment that the terminal was located and carry out fingerprint identification when the pressure value is greater than predetermineeing the pressure threshold value, avoid user's maloperation.
In step 103, the control screen displays the fingerprint hot spots using the fingerprint hot spot brightness.
For example, after determining the fingerprint brightness of the screen according to the ambient light brightness, the terminal controls the screen to display the fingerprint brightness using the fingerprint brightness.
In step 104, an off-screen fingerprint sensor is invoked to identify a user fingerprint corresponding to the press operation.
The technical scheme provided by the embodiment of the disclosure dynamically determines the fingerprint hot spot brightness of the screen according to the environment brightness by acquiring the environment brightness of the environment where the terminal is located, so that the fingerprint hot spot brightness can dynamically adapt to the diversity of the environment where the terminal is located, the problems of high brightness leakage and low fingerprint identification efficiency caused by adopting a fixed brightness value in the related technology are avoided, the comfort level of a user can be improved, the use of the user is facilitated, and the user experience is improved.
Fig. 2 is a flowchart illustrating a fingerprint identification method according to an exemplary embodiment, where an execution subject of the fingerprint identification method in this embodiment may be a terminal, and the fingerprint identification method illustrated in fig. 2 may include the following steps 201 and 205, where portions of this embodiment that are not described in detail may refer to corresponding descriptions of the embodiment in fig. 1:
in step 201, when a pressing operation on a screen of the terminal is detected, the ambient light brightness of the environment where the terminal is located is acquired.
In step 202, the fingerprint hot spot brightness of the screen is determined according to the ambient light brightness and the pre-obtained first mapping relationship between the ambient light brightness and the fingerprint hot spot brightness.
Optionally, in the first mapping relationship, the greater the ambient light brightness, the greater the brightness of the projected fingerprint hot spot.
In step 203, the exposure duration of the underscreen fingerprint sensor of the terminal is determined according to the ambient light brightness and the pre-obtained second mapping relationship between the ambient light brightness and the exposure duration.
For example, table 1 shows a table implementation based on the first mapping relationship and the second mapping relationship, see table 1:
TABLE 1
| Ambient brightness (optical unit nit) | Exposure time (ms) | Brightness of bright spot on screen (optical unit nit) |
| 600 | 40 | 600 |
| 500 | 70 | 500 |
| 400 | 100 | 400 |
| 300 | 130 | 300 |
| 200 | 170 | 200 |
| 100 | 220 | 100 |
The mapping relationship between the ambient light brightness and the fingerprint hot spot brightness, and the mapping relationship between the ambient light brightness and the exposure time are shown in table 1. For example, if the terminal is in a dim environment, if the ambient light brightness is 200nit, the exposure time of the fingerprint sensor under the screen is adjusted to 170ms, the fingerprint bright spot brightness is adjusted to 200nit, and by prolonging the exposure time, the bright spot brightness is reduced, the short-term influence of light leakage on the eyesight is reduced, and the user comfort is improved; if the terminal is in an outdoor strong light environment, if the environment light brightness is 600nit, the exposure time of the fingerprint sensor under the screen is adjusted to 40ms, the fingerprint bright spot brightness is adjusted to 600nit, the fingerprint bright spot is highlighted on the screen at the moment, the bright spot brightness is improved by reducing the exposure time, the pressing position is prompted, and the fingerprint solving is facilitated for a user.
In step 204, the control screen displays the fingerprint hot spots using the fingerprint hot spot brightness.
In step 205, the off-screen fingerprint sensor is controlled to perform exposure using the exposure duration, and the off-screen fingerprint sensor is called to identify the user fingerprint corresponding to the pressing operation.
According to the technical scheme provided by the embodiment of the disclosure, after the terminal acquires the ambient light brightness of the environment, the exposure time and the fingerprint hot spot brightness corresponding to the ambient light brightness can be determined by inquiring the mapping relation through acquiring the first mapping relation between the ambient light brightness and the fingerprint hot spot brightness and the second mapping relation between the ambient light brightness and the exposure time in advance, so that the exposure time and the fingerprint hot spot brightness can dynamically adapt to the diversity of the environment where the terminal is located, and the implementation is simple.
Fig. 3 is a flowchart illustrating a fingerprint identification method according to an exemplary embodiment, where an execution subject of the fingerprint identification method in this embodiment may be a terminal, and the fingerprint identification method illustrated in fig. 3 may include the following steps 301 and 306, where portions of this embodiment that are not described in detail may refer to corresponding descriptions of the embodiment in fig. 1:
in step 301, when a pressing operation for a screen of a terminal is detected, a pressure value of the pressing operation is acquired.
In step 302, it is determined whether the pressure value is greater than a preset pressure threshold: when the pressure value is larger than the preset pressure threshold value, turning to step 303; and when the pressure value is not greater than the preset pressure threshold value, ending the process.
In step 303, obtaining the ambient light brightness of the environment where the terminal is located; the preset pressure threshold is a preset critical value used for triggering the terminal to acquire the ambient light brightness of the environment where the terminal is located.
In an example, an ambient light sensor of the terminal is called to measure and obtain the ambient light brightness of the environment where the terminal is located.
In step 304, according to the ambient light brightness, the exposure duration of the under-screen fingerprint sensor of the terminal and the brightness of the fingerprint hot spot of the screen are determined.
In step 305, the control screen displays the fingerprint hot spot using the fingerprint hot spot brightness.
In step 306, the off-screen fingerprint sensor is called to expose using the exposure duration, and the user fingerprint corresponding to the pressing operation is identified.
According to the technical scheme provided by the embodiment of the disclosure, the preset pressure threshold value is set, the size relation between the pressure value and the preset pressure threshold value is judged, the ambient light brightness of the environment where the terminal is located can be measured and fingerprint identification is carried out only when the pressure value is larger than the preset pressure threshold value, and misoperation of a user is avoided.
