in one possible example, before the mobile terminal detects the face image, the method further includes:
detecting an event to be unlocked;
and opening a front camera to capture a human face image.
The event to be unlocked may be, for example, a desktop event to be unlocked, an application event to be unlocked, a file event to be unlocked, or the like, which is not limited herein. The event to be unlocked by the desktop refers to an event to be unlocked for locking the desktop, the event to be unlocked by the application refers to an event to be unlocked for a specific operation of the application, such as application starting, application deleting and the like, and the event to be unlocked by the file refers to an event to be unlocked for the file, such as an event to be unlocked for a target file.
The trigger condition for detecting the event to be unlocked by the mobile terminal may be that the mobile terminal detects the event to be unlocked of the application to be unlocked, where the event to be unlocked may be specifically triggered by touch operation, pressing operation, voice operation, and the like of the user, for example, for the mobile terminal in the off-screen standby state, pressing a power key or a Home key triggers the event to be unlocked, where the trigger condition is not limited.

In a possible example, the adjusting the focal length of the camera module when the face image is detected includes:
when the face image is detected, acquiring a distance parameter and integrity of the face image;
determining a zoom multiple according to the distance parameter and the integrity;
and adjusting the focal length of the camera module according to the zoom multiple.
The distance parameter is the distance between the mobile terminal and the face of the user, and the integrity is the integrity of the face contour.

Wherein, the camera module preview image's of the multiple that zooms width and degree of depth can be adjusted.
The specific implementation manner of determining the zoom multiple according to the distance parameter and the integrity may be that a reference range of the zoom multiple is roughly determined according to the distance parameter, and a target zoom multiple in the reference range of the zoom multiple is accurately determined as the zoom multiple according to the integrity.
And determining a zoom multiple which enables the integrity of the face image to reach a preset integrity threshold according to the distance parameter and the integrity.
Wherein, adjust the focus of above-mentioned camera module according to above-mentioned zoom multiple and can be according to above-mentioned zoom multiple devices such as step motor of adjusting mobile terminal camera module to adjust the focus of camera module, make the definition of face image reach and predetermine the threshold value.
Therefore, in the example, the mobile terminal determines the zoom multiple according to the distance parameter and the integrity instead of using the fixed zoom multiple, which is beneficial to improving the definition and the integrity of the face image, thereby improving the accuracy of focusing of the mobile terminal.
In this possible example, the determining the zoom factor according to the distance parameter and the completeness includes:

In a possible example, the acquiring at least one biological image when the sharpness of the face image is detected to be greater than a preset threshold includes:
acquiring the security level of an event to be unlocked;
inquiring a mapping relation between a preset security level and a biological image definition threshold according to the security level, and determining a definition threshold corresponding to the security level;
and when the definition of the face image is greater than or equal to the definition threshold, acquiring the at least one biological image according to the security level of the event to be unlocked.
The security level may be set by a system or may be set by a user, and is not limited herein, for example, the security level may be set to be a high security level, a medium security level, or a low security level, and different definitions are set according to different security levels, for example, when the security level is high, a higher definition threshold value needs to be corresponded, and when the security level is low, a lower definition threshold value needs to be corresponded.
The at least one biological image is acquired according to the security level of the event to be unlocked, all features of two biological images of the face image and the iris image can be acquired at a high security level, partial features of the two biological images of the face image and the iris image can be acquired at a medium security level, or one biological image of the face image and the iris image can be acquired at a low security level.

determining a matching degree threshold value of the at least one biological image according to the definition of the face image;
matching the at least one biological image with the preset biological template set;
and when the matching degree of the at least one biological image and the preset biological template set is detected to be greater than or equal to the matching degree threshold value, executing unlocking operation.
The implementation manner of the mobile terminal executing the unlocking operation may be to switch the current state of the mobile terminal to an unlocking state, where the current state includes a screen locking state, a disabled state, and the like, and is not limited here.
Wherein the set of biological templates comprises at least one of: one or more iris information templates and one or more face information templates.
The iris information template is an iris data template, and the iris data template is a collective image of correspondence between the positions of characteristic points of the iris of the registered user and characteristic values (the characteristic values may be capacitances, inductances, voltages, currents, relative values, and the like) of specific points.
The face information template is a face data template, and the fingerprint data template is a set of correspondence between positions of feature points of the face of the registered user and feature values of the feature points (the feature values may be capacitances, inductances, voltages, currents, relative values, and the like).
The definition threshold value is high, the corresponding matching degree threshold value is high, the definition threshold value is low, the corresponding matching degree threshold value is low, and the matching speed of the mobile terminal can be improved.
Therefore, in the example, the mobile terminal determines the matching degree threshold according to the definition of the face image, and performs the unlocking operation according to the matching degree threshold, so that the security of the mobile terminal is ensured, and meanwhile, the matching speed and flexibility of the mobile terminal are improved.
It can be seen that, in the embodiment of the present invention, the mobile terminal firstly adjusts the focal length of the camera module when detecting the face image; secondly, when the definition of the face image is detected to be larger than a preset threshold value, at least one biological image is collected; and finally, executing unlocking operation when the at least one biological image is successfully matched with the preset biological template set.
