Depend on linguistic context, word as used in this " if " can be construed as " ... time " or " when ... time " or " in response to determining ".

As shown in Figure 1, Fig. 1 is a kind of display state adjustment method according to an exemplary embodiment, comprises the following steps:

In a step 101, whether detection currently exists the target user that can see content shown on the screen of terminal, and described target user is the user except the pre-set user of described terminal.

The method provided in disclosure embodiment may be used for terminal, such as, and smart mobile phone, panel computer, personal digital assistant (PersonalDigitalAssistant, PDA) etc.

In this step, can selection of land, described terminal can first detect whether self has opened privacy protection function. If detecting after opening described privacy protection function, just whether detection currently exists described target user.

In disclosure embodiment, described terminal can in the following manner in any one detect whether open described privacy protection function:

Whether first kind of way, detect default virtual icon corresponding with privacy protection function in the status bar of described terminal corresponding to opened condition.

Under this kind of mode, described terminal can export described default virtual icon in status bar. Can selection of land, described preset virtual icon can be default virtual slider icon, as shown in Figure 2.

Whether described terminal can detect described default virtual icon corresponding to opened condition according to correlation technique; virtual icon is preset corresponding to opened condition if described; then described terminal can determine that user needs to carry out secret protection, namely opens described privacy protection function.

2nd kind of mode, whether the described screen detecting described terminal is lit.

Under this kind of mode, described terminal can be given tacit consent to after described screen is lit, and just opens described privacy protection function. Correspondingly, if described screen is locked, described privacy protection function is just closed. If described screen is lit; can determine that user currently needs to check content shown on described screen; if the target user now existed outside pre-set user sees described content; the leakage of user profile will be caused; therefore described terminal can be determined now to need protection privacy of user; improve the accuracy judging whether to need to protect privacy of user, and operability height. Correspondingly; if described screen is locked; can determine that user currently no longer checks the described content of described display on described screen; therefore; can automatically determine that described privacy protection function is closed; now described terminal no longer needs whether detection exists described target user, has saved the calculating resource of described terminal.

According to correlation technique, described terminal detects whether described screen is lit, if be lit, then determine that user needs to carry out secret protection, namely open described privacy protection function.

In disclosure embodiment, after described terminal detects open described privacy protection function, whether detection, except the pre-set user of described terminal, exists the described target user that other can see content shown on the described screen of described terminal.

Can selection of land, described terminal can open preassembled front-facing camera, is gathered the image of the visual range of the screen being positioned at described terminal in real time by described front-facing camera. And then the target facial image whether including described target user in described image by detecting, determine whether there is the described target user that can see content shown on described screen.

In correlation technique, when starting described front-facing camera, the view finder of described front-facing camera also can synchronously be opened. In the disclosed embodiments, in order to not affect described content shown on the described screen of described terminal, it is possible to close described view finder while the backstage of described terminal starts described front-facing camera. Namely not showing the view finder of described front-facing camera on the described screen of described terminal, described front-facing camera is all the time at running background.

After described camera collects described image according to correlation technique, first described image is carried out recognition of face by described terminal, it is determined that go out the face number of the face that described image comprises. Judge whether described face number exceedes user's number of described pre-set user, if described face number exceedes described user's number, it is possible to directly determine that described image comprises the described target facial image of the described target user except described pre-set user. No longer need to carry out the follow-up works such as face coupling, so that it may current there is the described target user that can see content shown on the described screen of described terminal to determine, it is to increase terminal operating speed, saved the calculating resource of described terminal.

Such as, it is 2 that terminal can arrange user's number of pre-set user, if the face number of the face that the image being collected the visual range of the screen being arranged in described terminal by the front-facing camera of described terminal is comprised is 3, then can determine that described image comprises the target facial image of described target user. Further, it may be determined that there is described target user.

In disclosure embodiment, if the described face number of described face that described image comprises does not exceed described user's number, described terminal can obtain the facial image only including described face according to correlation technique from described image. Further, according to correlation technique, the default facial image of described facial image with the described pre-set user prestored is mated. If do not mated, then can determine that described image comprises the described target facial image of described target user. Further, it may be determined that current exist the described target user that can see content shown on the described screen of described terminal.

Such as, it is 2 that terminal can arrange user's number of pre-set user, and default facial image a and b of the described pre-set user that prestored, if the face number of the face that the image being collected the visual range of the screen being arranged in described terminal by the front-facing camera of described terminal is comprised is 1, then described terminal needs the facial image c of the described face obtaining in described image, described facial image c is mated respectively with described default facial image a and b, if described facial image c does not all mate with described default facial image a and b, then can determine described image exists described target user, further, the current described target user that there is the content shown by can seeing on the described screen of described terminal can be determined. otherwise can determine that described image does not exist described target user.

After described terminal determines the current described target user that there is the content shown by can seeing on the described screen of described terminal by said process, it is possible to continue to perform step 102. If currently there is not described target user; even if so described terminal has opened described privacy protection function; then the display state of described screen also can not be regulated by described terminal, so that user can see content shown on described screen clearly, promotes Consumer's Experience.

In a step 102, the display state of described screen is adjusted.

In this step; after described terminal can have been opened described privacy protection function detecting described terminal and there is described target user; the current described backlight brightness values of described screen is turned down according to correlation technique, can selection of land, it is possible to turn down first and preset backlight brightness values. Described first presets backlight brightness values can guarantee that described target user cannot see content shown on the described screen of described terminal when current backlight.

In above-described embodiment, terminal detects the target user that currently whether there is content shown on the screen that can see described terminal automatically, and described target user is the user outside the pre-set user of described terminal. If except described pre-set user, also have other described target user can see content shown on described screen, it may be determined that now to need to protect the privacy of described pre-set user, it is to increase to judge whether the accuracy needing to protect privacy of user. Further, described terminal avoids described target user to see described content by adjusting the display state of described screen automatically, thus avoid the user profile being stored in described terminal to be seen by described target user and cause reveal problem.
