Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and explanation thereof are used for explanation the present invention, but not as a limitation of the invention.
The embodiment of the invention provides a kind of mobile terminal screen latch-release method and device, and the present invention is described in detail below in conjunction with accompanying drawing.
Embodiment one
Fig. 1 is a kind of mobile terminal screen latch-release method flow diagram that the embodiment of the invention provides, and as shown in Figure 1, described method comprises:
S101 judges that portable terminal is in the screen locking state.
In embodiments of the present invention, portable terminal at first will judge self whether to be in the screen locking state, if portable terminal is in the state of normal use, then do not carry out following step, if portable terminal is in the screen locking state, be that most of button that the true key board of any touch instruction or portable terminal was closed, do not responded to touch-screen is in not responsive state, then portable terminal is judged self current screen locking state that is in.The screen locking state can prevent portable terminal when not used by the user and since the touch-screen that causes of a variety of causes or button by mistake by situation.
S102, the camera by portable terminal obtains image information.
In embodiments of the present invention, portable terminal needs further to differentiate the user and whether need to use portable terminal after judgement self is in the screen locking state, and this moment, portable terminal can be opened camera, obtained the image information in the external world by camera.When the user need use portable terminal, its face can face the screen of portable terminal usually, so the preposition camera that portable terminal is positioned at screen one side can get access to the image information that has user's face pattern.If when portable terminal is arranged in bag or the pocket, its camera can't get access to the image information that has face pattern.
S103 judges whether comprise face pattern in the described image information.
In embodiments of the present invention, after portable terminal gets access to image information by camera, further judge in the image information that gets access to whether comprise face pattern.If do not comprise face pattern in the image information, the preceding nobody's face of camera of mobile terminal screen one side then is described, therefore portable terminal is judged does not have the user to use portable terminal this moment, thereby keeps portable terminal to be in the screen locking state.Otherwise, when comprising face pattern in the image information, people's face has appearred before the camera of mobile terminal screen one side then is described, and therefore portable terminal judges that this moment, very possible user to be ready using portable terminal, enters step S104.
S104 when comprising face pattern in described image information, removes the screen locking state of portable terminal.
In embodiments of the present invention, when portable terminal detects when comprising face pattern in the image information that camera obtains, judge that this moment, very possible user to be ready using portable terminal, and then remove the screen locking state of portable terminal, enter normal operating condition.Need not the user in the whole process and import any unlock command, and because portable terminal is just removed the screen locking state of portable terminal when only comprising face pattern in image information, the mistake of having avoided portable terminal to be arranged in taking place in bag or the pocket is by situation.
Preferably, in embodiments of the present invention, when incoming call, note or other information, portable terminal can be sounded or prompting such as vibrations, if the user picks up portable terminal this moment, portable terminal can detect in the image information that camera obtains and comprise face pattern, and then the direct connecting incoming call or directly show other information such as note of portable terminal need not the user and imports any unlock command.
In embodiments of the present invention, when not comprising face pattern in the image information, portable terminal will keep the screen locking state.
The mobile terminal screen latch-release method that the embodiment of the invention provides, can when facing portable terminal, the user automatically terminate the screen locking state, make portable terminal avoids button when the screen locking state mistake by, simultaneously greatly reduced the time that the user imports unlock command, improved efficient, reduce the wearing and tearing of touch-screen or button, increased the serviceable life of portable terminal, and improved user's experience.
Embodiment two
