The above terminal is only an example. Rather than exhaustive, including but not limited to the above terminals. The terminal described in the embodiment of the present invention is not only equipped with a fingerprint identification module, but the fingerprint identification module is used to collect fingerprint information of the user. The terminal described in the embodiment of the present invention may also be installed with a light intensity sensor or a color temperature sensor. The light intensity sensor is used to collect an ambient brightness value, and the color temperature sensor is used to collect an ambient color temperature value.

FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for unlocking a terminal according to an embodiment of the present invention. The method for unlocking a terminal described in this embodiment includes the following steps:

101. Acquire fingerprint information and environment parameters when the user presses the fingerprint identification module.

In the embodiment of the present invention, the environment parameter may be an ambient brightness value and/or an ambient color temperature value. When detecting that the user presses the fingerprint identification module, the terminal may collect fingerprint information through the fingerprint recognition module, and at the same time, collect the fingerprint information through the light intensity sensor. The ambient brightness value is collected by the color temperature sensor. Typically, the fingerprinting module is integrated with the dome key (similar to the Home button).

It should be noted that, when the pressing force of the pressing fingerprint recognition module in step 101 is small (for example, between 0 and 0.1 N), the terminal may also detect that the fingerprint recognition module is pressed, that is, when the user touches the fingerprint. When the module is identified, fingerprint information and environmental parameters can be obtained.

Optionally, before step 101, the terminal may also be in an off-screen state.

Optionally, after step 101, the display parameter corresponding to the environment parameter may also be determined. Then, in step 104, the display screen is illuminated according to the display parameter. The specific implementation manner of determining the display parameter corresponding to the environment parameter is: determining the display parameter corresponding to the environment parameter in step 101 according to the correspondence between the preset environment parameter and the display parameter.

Optionally, in the embodiment of the present invention, the fingerprint information may also be a pressing force when the user presses the fingerprint recognition module and a fingerprint feature collected by the fingerprint recognition module. The pressing force may be the maximum pressing force or the average pressing force of the user pressing the fingerprint recognition module.

Further, in the embodiment of the present invention, the fingerprint information may also be a pressing time when the user presses the fingerprint identification module and a fingerprint feature collected by the fingerprint identification module. The pressing time may be that pressing the fingerprint may be detecting a pressing time between the user touching the fingerprint recognition module and leaving the fingerprint recognition module, or the pressing time may be when the fingerprint recognition module is pressed, the pressing force is greater than a certain threshold. Corresponding pressing time. The fingerprint feature may be a feature texture of the fingerprint collected by the fingerprint recognition module, or a feature point collected by the fingerprint recognition module.

Further optionally, in the embodiment of the present invention, the fingerprint information may also be a fingerprint recognition module for the user. The pressing area of the time and the characteristic texture of the fingerprint collected by the fingerprint recognition module. The pressing area may be an average pressing area in the process of pressing the fingerprint recognition module, that is, an average value of the pressing area detected between the user pressing the fingerprint recognition and the finger leaving the fingerprint recognition module.

Further, in the embodiment of the present invention, the fingerprint information may also be the number of presses when the user presses the fingerprint recognition module and the fingerprint feature collected by the fingerprint recognition module. The user can press the fingerprint recognition module multiple times within a preset time, and record the number of presses of pressing the fingerprint recognition module, and use the number of presses as part of the fingerprint information, and each time the fingerprint recognition module is pressed, Capture fingerprint features. During the unlocking process, the terminal is unlocked as long as the number of presses meets the threshold and the fingerprint feature is matched at least once in the process of pressing the fingerprint recognition module multiple times.

Optionally, when the user presses the fingerprint identification module, an interrupt request may be generated, and then the fingerprint information and the environmental parameters are acquired.

102. Match the fingerprint information with preset fingerprint information.

In the embodiment of the present invention, the fingerprint information may be from fingerprint information of one finger or fingerprint information of multiple fingers. The preset fingerprint information is fingerprint information of multiple fingers, and the fingerprint information is also from the same as the preset fingerprint information. Fingerprint information of the finger may be matched successfully.

Optionally, between

steps

102 and 103, the method further includes the step of: detecting whether the pressing force for the fingerprint identification module is greater than a preset threshold, and if yes, performing step 103. The preset threshold may be set by the user or the system defaults. When the pressing force is greater than the preset threshold, the fingerprint recognition module is completely pressed.

103. When the fingerprint information and the preset fingerprint information are successfully matched, unlock the terminal.

In the embodiment of the present invention, when the fingerprint information and the preset fingerprint information are successfully matched, the terminal unlocks the terminal. Optionally, the fingerprint identification may also be applied to the payment. For example, when the fingerprint information and the preset fingerprint information are successfully matched, the terminal may allow the payment to be made.

104. Illuminate a display screen of the terminal, and adjust a display effect of the display screen according to the environmental parameter.

In the embodiment of the present invention, after the terminal is unlocked, the display screen of the terminal may be illuminated. Specifically, how to adjust the display effect of the display screen can be adjusted by environmental parameters. For example, when the user presses the fingerprint recognition module, the terminal may obtain an environment parameter. When the environment parameter is an ambient brightness value, the brightness of the display screen is adjusted according to the ambient brightness value. When the environmental parameter is the ambient color temperature value, according to the Ambient color temperature The value adjusts the chromaticity of the display. When the environmental parameter is the ambient brightness value and the ambient color temperature value, the brightness and chromaticity of the display can be adjusted according to the ambient brightness value and the ambient color temperature value. Therefore, the brightness of the display screen can be adjusted according to the brightness of the environment, that is, if the environment is bright, the brightness of the screen can be slightly dimmed, and when the environment is dark, the brightness of the screen can be slightly brightened, so that the brightness of the screen is more suitable for people. At the same time, the chromaticity of the display screen can be adjusted according to the ambient color temperature, wherein the color temperature is the most common indicator indicating the spectral quality of the light source. The chromaticity of the screen display can be adjusted according to the spectral quality of the light source in the environment, so that the chromaticity of the screen display is suitable for the environment, and thus, it is more suitable for the human eye.

Optionally, when the environmental parameter is the ambient brightness value and the ambient color temperature value in the current environment, the terminal may match the corresponding display parameter in the pre-stored database according to the ambient brightness value and the ambient color temperature value, and adjust the display according to the display parameter. The display effect. In a specific implementation, the display parameters corresponding to different brightness values and different ambient color temperature values may be collected in different environments, and the display parameters may be brightness and chromaticity of the screen display, so that different brightness values and different color temperature values are corresponding. The display parameters are stored in the database. Then, when the terminal obtains the ambient brightness value and the ambient color temperature value in the current environment, the corresponding display parameters can be directly matched, and the display effect of the display screen is adjusted according to the display parameter. This embodiment can speed up the acquisition time of the display parameters, and the display parameters obtained under the experimental verification are more suitable for the user.

As shown in Figure 1a, the existing fingerprint unlocking process consists of two routes (parallel): the first route: interrupt (interrupt request) - fingerprint information collection - fingerprint matching - unlock completion - bright screen; second route: fingerprint The identification module is pressed (ie, detecting whether the pressing force for the fingerprint recognition module is greater than a preset threshold) - the bright screen, the fingerprint identification module being pressed may include three time periods, respectively: before collecting the fingerprint information (FIG. 1a) '1' in the middle, between the acquisition of fingerprint information and fingerprint matching ('2' in Figure 1a) and between fingerprint matching and unlocking completion ('3' in Figure 1a). The difference is that the first route is completed when the user presses the fingerprint but has not pressed it. During the unlocking process, the dome button generates an interrupt to wake up the screen for about 60-100ms, but if the first route is not completed, the user presses it, and the unlocking time is extended by the overlay because It is necessary to count the fingerprint acquisition time and the fingerprint matching time, especially in the case of '1' in Fig. 1a, the longest time.

In practical applications, the entire screen-off compression time fluctuates between 100ms and 400ms. One reason for the large fluctuation is whether the user has turned on the automatic light perception. The fingerprint information collection and unlocking time is relatively stable and short, but the user perceives. It is terminated by the screen light, and the fingerprint is not unlocked as the end point. In addition to the system response, there is a premise that the screen reads the environmental parameters through the sensor before the display is bright, and then obtains the display effect of the display screen corresponding to the environmental parameters; the screen parameters of the environmental parameters are retrieved. It takes a certain time, usually more than 50ms; the display finally lights up, which is the most suitable for displaying the effect at this time. Therefore, as shown in FIG. 1b, after the terminal is generated, the environmental parameters are collected by the third route (dashed line), and after the unlocking is completed, the environment parameter is directly used to illuminate the screen. Since the environmental parameters are prepared before the bright screen operation, the fingerprint unlocking time is shortened compared to the prior art.

When the user presses the fingerprint identification module, the fingerprint information and the environment parameter are obtained, and the fingerprint information is matched with the preset fingerprint information. When the fingerprint information and the preset fingerprint information are successfully matched, the terminal is performed. Unlock and illuminate the display of the terminal and adjust the display of the display according to the environmental parameters. Therefore, when the fingerprint recognition module is pressed, the environment parameter is acquired, and after the unlocking is successful, the environment parameter is directly called to adjust the brightness of the display, thereby reducing the unlocking time.

FIG. 2 is a schematic flowchart diagram of a second embodiment of a method for unlocking a terminal according to an embodiment of the present invention. The method for unlocking a terminal described in this embodiment includes the following steps:

201. Acquire fingerprint information and environment parameters when the user presses the fingerprint identification module.

In the embodiment of the present invention, the environment parameter may be an ambient brightness value and/or an ambient color temperature value. When detecting that the user presses the fingerprint identification module, the terminal may collect fingerprint information through the fingerprint recognition module, and at the same time, collect the fingerprint information through the light intensity sensor. The ambient brightness value is collected by the color temperature sensor.

202. When the fingerprint information is a pressing force of the pressing fingerprint recognition module and a fingerprint feature collected by the fingerprint identification module, determining whether the pressing force is in a preset range.

In the embodiment of the present invention, the fingerprint recognition module can integrate the pressure sensor. Therefore, in the process of pressing the fingerprint identification module by the user, not only the pressing force generated by the user in pressing the fingerprint recognition module but also the fingerprint recognition can be collected. The module collects fingerprint characteristics of the user. When the fingerprint information is the pressing force of pressing the fingerprint recognition module and the fingerprint feature collected by the fingerprint recognition module, the terminal may determine whether the pressing force is in a preset range. Among them, the preset range can be 0 cattle to 5 cattle, 2 cattle to 4 cattle, more than 8 cattle, less than 10 cattle, 12.5 cattle to 18 cattle and so on.

203. If yes, match the fingerprint feature with the preset fingerprint feature.

In the embodiment of the present invention, when the pressing force is in a preset range, the terminal may match the fingerprint feature with the preset fingerprint feature. Wherein, the fingerprint feature can be a fingerprint image, then the fingerprint collected can be compared The similarity between the image and the fingerprint image corresponding to the preset fingerprint feature. If the similarity reaches a certain threshold, the fingerprint feature can be considered to be successfully matched with the preset fingerprint feature. If the similarity does not reach the certain threshold, it can be considered The fingerprint feature does not match the preset fingerprint feature. The fingerprint feature can be the characteristic texture of the fingerprint, that is, the feature contour of the fingerprint included in the fingerprint image. Then, the similarity between the collected feature texture and the preset feature texture can be compared, and if the similarity reaches a certain threshold, the The feature line and the preset feature line are successfully matched. If the similarity does not reach the certain threshold, the feature line and the preset feature line are not matched. The fingerprint feature can be a feature point of the fingerprint, that is, a corner point of the fingerprint included in the fingerprint image, such as a Harris corner point, a Scale Invariant Feature Transform (SIFT) corner point, then the feature line of the acquired feature can be compared. The similarity between the preset feature lines, if the similarity reaches a certain threshold, the feature point can be considered to be successfully matched with the preset feature point. If the similarity does not reach the certain threshold, the feature point and the preset feature can be considered. The points do not match.

Alternatively, the fingerprint identification may also be applied to the payment, for example, the terminal may allow the payment to be made when the fingerprint feature matches the preset fingerprint feature successfully.

205. Light up a display screen of the terminal, and adjust a display effect of the display screen according to the environmental parameter.

In the embodiment of the present invention, after the terminal is unlocked, the display screen of the terminal may be illuminated. Specifically, how to adjust the display effect of the display screen can be adjusted by environmental parameters. For example, when the user presses the fingerprint recognition module, the terminal may obtain an environment parameter. When the environment parameter is an ambient brightness value, the brightness of the display screen is adjusted according to the ambient brightness value. When the environmental parameter is the ambient color temperature value, according to the The ambient color temperature value adjusts the chromaticity of the display screen. When the environmental parameter is the ambient brightness value and the ambient color temperature value, the brightness and chromaticity of the display screen can be adjusted according to the ambient brightness value and the ambient color temperature value. Therefore, the brightness of the display screen can be adjusted according to the brightness of the environment, that is, if the environment is bright, the brightness of the screen can be slightly dimmed, and when the environment is dark, the brightness of the screen can be slightly brightened, so that the brightness of the screen is more suitable for people. At the same time, the color of the display can be adjusted according to the ambient color temperature. The chromaticity of the screen display can be adjusted according to the spectral quality of the light source in the environment, so that the chromaticity of the screen display is suitable for the environment, and thus, it is more suitable for the human eye.

Optionally, when the environment parameter is the ambient brightness value and the ambient color temperature value in the current environment, the terminal may match the corresponding display parameter in the pre-stored database according to the ambient brightness value and the ambient color temperature value. Adjust the display of the display according to the display parameters. In a specific implementation, the display parameters corresponding to different brightness values and different ambient color temperature values may be collected in different environments, and the display parameters may be brightness and chromaticity of the screen display, so that different brightness values and different color temperature values are corresponding. The display parameters are stored in the database. Then, when the terminal obtains the ambient brightness value and the ambient color temperature value in the current environment, the corresponding display parameters can be directly matched, and the display effect of the display screen is adjusted according to the display parameter. This implementation can speed up the acquisition time of the display parameters, and the display parameters obtained under the experimental verification are more suitable for the user.

When the user presses the fingerprint recognition module, the fingerprint information and the environment parameter are obtained by the user in the embodiment of the present invention. When the fingerprint information is the pressing force of the pressing fingerprint recognition module and the fingerprint feature collected by the fingerprint recognition module, the pressing force and the fingerprint are pressed. When the features match successfully, the terminal is unlocked, and the display screen of the terminal is illuminated, and the display effect of the display screen is adjusted according to the environment parameter. Therefore, when the fingerprint recognition module is pressed, the environment parameter is obtained. After the unlocking is successful, the environment parameter is directly called to adjust the brightness of the display, thereby reducing the unlocking time, that is, directly calling the environmental parameter after unlocking, so that the adjustment is performed. The rear screen display effect is more suitable for the human eye.

If the similarity does not reach the certain threshold, the feature line and the preset feature line are not matched. The fingerprint feature may be a feature point of the fingerprint, that is, a corner point of the fingerprint included in the fingerprint image, such as a Harris corner point and a SIFT corner point, then the similarity between the acquired feature line and the preset feature line may be compared. If the degree reaches a certain threshold, the feature point can be considered to be successfully matched with the preset feature point.
