Triggering mode.
In the embodiment of the present application, the desired image capture module for starting mobile phone of user is also required to through above-mentioned several operations
Mode, and above-mentioned several modes of operation are generally not easy by user's false triggering under unconscious situation, thus use this side
Formula can also avoid the maloperation of user to a certain extent.
After mobile phone detects user through the above way to the touch operation of mobile phone screen, mobile phone can start preposition camera shooting
Head, and Image Acquisition is carried out by the front camera.
Step 102：Judge by executing whether step 101 the image collected is facial image, and the facial image
Eyes sight target whether be screen display area；If the determination result is YES, 103 are thened follow the steps；If judging result
It is no, then continues through image capture module and carry out Image Acquisition；
What needs to be explained here is that usually when user needs to unlock using mobile phone, user often holds mobile phone simultaneously
Mobile phone is placed in face of oneself, then in this case, after user triggers image capturing request by aforesaid operations, mobile phone is rung
The face-image of user should can be generally collected by the front camera after the request starts front camera；And
When user is due to maloperation and when triggering mobile phone and starting the front camera, at this time since user need not use mobile phone, because
And before mobile phone will not generally be placed in user plane, mobile phone can not also collect the face of user by the front camera in this case
