Embodiment
Refer to Fig. 1, screen unlock method one embodiment of the present invention comprises:
Step S101: make the infrared receiving tube of mobile terminal receive the infrared light be reflected back from infrared transmitting tube transmitting;
The button operation of mobile terminal response user, lights the screen being in screen lock state.Now, when mobile terminal is in screen lock state, makes the infrared receiving tube in mobile terminal receive infrared transmitting tube and launch and the infrared light that reflects.In actual applications, when there being object near proximity transducer, the infrared light that infrared transmitting tube is launched is reflected by the object and is received by infrared receiving tube.When do not have object near time, infrared receiving tube does not receive the infrared light that infrared transmitting tube sends.Arrange a barricade between usual infrared transmitting tube and infrared receiving tube, the infrared light launched to prevent infrared transmitting tube is directly received by infrared receiving tube without reflection;
Step S102: make the proximity transducer of mobile terminal successively detect the multiple infrared light intensity obtained in the schedule time, and light intensity is converted into the baseband processor that numerical information sends to mobile terminal;
The proximity transducer Real-Time Monitoring infrared receiving tube of mobile terminal receives the situation of infrared light, when infrared receiving tube receives infrared light, proximity transducer successively detects the multiple infrared light intensity obtained in the schedule time, and the numerical information that the baseband processor that light intensity is converted into mobile terminal can identify, then send to baseband processor;
Step S103: make the baseband processor of mobile terminal receive multiple numerical information being converted into respective light intensities, and calculate current light intensity situation of change;
Baseband processor to the multiple numerical informations being converted into respective light intensities received, and calculates current light intensity situation of change.Such as when object is by during as far as nearly close proximity transducer surveyed area, proximity transducer detection obtains infrared light intensity data and is gradient to D (max) from D (0), wherein D represents light intensity, and it is that D (0) is gradient to D (max) that baseband processor calculates current light intensity.In an embody rule, infrared receiving tube is set at the schedule time such as 10 seconds interior focusing intensity samplings ten times, and get its mean value, such as D (0)=(S (0)+S (1)+...+S (9))/10, the S light intensity value representing sampling; If D (n) is >=D (n-1), the infrared light strength increase received, shows object near sensor surveyed area; If D (n) no longer increases, namely reach D (max), show that object has touched sensor surveyed area; If D (max) is gradient to again D (0), show object just away from sensor surveyed area;
Step S104: judge whether the situation that current light intensity changes belongs to corresponding to the first mode of unlocking screen, if by unlocking screen;
By judging whether the situation of the current light intensity change that baseband processor obtains belongs to corresponding to the first mode of unlocking screen, if it is by unlocking screen.Wherein, in an embody rule, here first mode is: current light intensity is changed to light intensity and is increased by initial value until a maximal value, initial value is become again from maximal value, wherein light intensity is T1 by initial value to time of maximal value, the time being become initial value from maximal value is T2, and T1 is greater than twice T2.If the situation of current light intensity change does not belong to corresponding to the first mode of unlocking screen, then judge whether the situation that current light intensity changes belongs to the second pattern abandoning unlocking screen.Wherein, second pattern is: current light intensity is changed to light intensity and is increased by initial value until a maximal value, then becomes initial value from maximal value, and wherein light intensity is T1 by initial value to time of maximal value, the time being become initial value from maximal value is T2, and T1 is less than twice T2.
