However, the situation of false triggering often occurs, so that the camera of the mobile terminal is frequently started, more electric quantity is consumed, and the endurance time of the mobile terminal is reduced.
In the invention, the camera can be controlled to detect the face image under the condition that the mobile terminal is turned off and the camera is in a low-power-consumption running state. If the camera detects the face image, and the detected face image is matched with the preset face image, the mobile terminal can be unlocked. The situation that the camera is frequently started to perform face recognition due to false triggering can be effectively reduced, and the power consumption of the mobile terminal is reduced.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The unlocking method provided by the embodiment of the invention is applied to the mobile terminal with the camera. Under the condition that the mobile terminal is in a screen-off state and the camera is in a low-power-consumption running state, controlling the camera to detect a face image, wherein the low-power-consumption running state is a state when the running power of the camera is smaller than a preset power value; and if the face image is detected, unlocking the mobile terminal under the condition that the face image is matched with a preset face image. Therefore, when the mobile terminal is turned off and the camera is in a low-power-consumption running state, the camera can be controlled to detect the face image.

Referring to fig. 2, fig. 2 is a flowchart of another unlocking method provided in an embodiment of the present invention, and the method is applied to a mobile terminal having a camera. The main difference between this embodiment and the previous embodiment is that the process of performing face recognition and then unlocking the mobile terminal is elaborated when the spatial posture of the mobile terminal changes within a preset time period and the camera detects a face image of the user. As shown in fig. 2, the method comprises the following steps:
In step 201, it may be detected whether a spatial posture of the mobile terminal changes within a preset time period.
In step 202, under the condition that the mobile terminal is in a screen-off state, the spatial posture of the mobile terminal changes within a preset time period, and the camera is in a low-power-consumption operation state, the camera may be controlled to detect a face image. The low-power-consumption running state is a state when the running power of the camera is smaller than a preset power value. Therefore, when the space posture of the mobile terminal changes within a preset time period, the camera is controlled to detect the face image, the condition is stricter, the occurrence of the situation that the camera is frequently opened for face recognition due to false triggering can be effectively reduced, and the power consumption of the mobile terminal is reduced.

and displaying the unread message.
And under the conditions that the mobile terminal is turned off, unread messages exist in the mobile terminal and the camera is in a low-power-consumption running state, the camera can be controlled to detect the face image. If the camera detects the face image, the mobile terminal can compare the detected face image with a preset face image. And under the condition that the detected face image is matched with the preset face image, the mobile terminal can be unlocked, and unread messages can be displayed. Therefore, when the mobile terminal is inconvenient to operate by both hands, if unread messages exist in the mobile terminal, the camera can be controlled to detect the face image. If the face image is detected and the detected face image is matched with the preset face image, the mobile terminal can be unlocked and the unread message can be displayed. Is convenient and quick.
Optionally, after the step of controlling the camera to detect the face image, the method further includes:
and if the face image is detected and the face image is not matched with the preset face image, sending alarm information when the screen of the mobile terminal is in a screen-off state.
If the camera in the low-power-consumption running state detects the face image and the detected face image is not matched with the preset face image, alarm information can be sent when the screen of the mobile terminal is in a screen-off state. At this time, other people may try to unlock the mobile terminal, so that the mobile terminal can be locked in a screen-off state, other people are not allowed to perform any operation on the mobile terminal, and alarm information can be sent to a preset mailbox. Therefore, other people can be prevented from stealing information in the mobile terminal, and privacy is guaranteed not to be leaked out.
Optionally, after the step of unlocking the mobile terminal, the method further includes:
and if the camera detects at least two face images, outputting privacy protection prompt information.
After the mobile terminal is unlocked, if the camera detects at least two face images, privacy protection prompt information can be output. For example, when the user is outdoors, if there are many people outdoors, when the user uses the mobile terminal, the content displayed on the screen of the mobile terminal is likely to be seen by others. Therefore, if the camera in the low-power-consumption running state detects at least two face images, the mobile terminal can output privacy protection prompt information to remind a user of privacy protection. The risk of privacy leakage can be effectively reduced.
The unlocking method provided by the embodiment of the invention is applied to the mobile terminal with the camera. If the space posture of the mobile terminal changes within a preset time period, the camera can be controlled to detect the face image under the conditions that the mobile terminal is turned off and the camera is in a low-power-consumption running state. If the camera detects the face image, and the detected face image is matched with the preset face image, the mobile terminal can be unlocked. The situation that the camera is frequently started to perform face recognition due to false triggering can be effectively reduced, and the power consumption of the mobile terminal is reduced.
