Fig. 3 is the flow chart of the method for dynamic adjustments range sensor threshold value of the present invention, and it can be realized by mobile terminal 100 as shown in Figure 1 or 2, comprises that step has:
Step S301, the first determining step, when unlatching range sensor is conversed, whether judging distance transducer detects near state.Detect the close state-detection distance whether distance between mobile terminal 100 and user's head is less than acquiescence.If the first judge module 10 detects near state, can directly screen be switched to the screen state that goes out from bright screen state.
Step S302, threshold value regulating step, if do not detect near state, in predetermined system is gone out screen time T, at least increases predetermined value or predetermined ratio by close the state-detection distance of range sensor, to be more prone to detect close state.
Step S303, the second determining step, according to the close state-detection distance after each adjusting, whether judging distance transducer detects near state.
Step S304, the first screen step of going out, if detect near state after regulating near state-detection distance, switches to from bright screen state the screen state that goes out by screen.Like this, when talk-through and mobile terminal leave head, mobile terminal 100 still can be realized automatic bright screen.
Step S305, the second screen step of going out, if system is gone out, screen time T does not detect yet near state after arriving, and screen is switched to the screen state that goes out from bright screen state.Now range sensor is not all the time near head when call explanation, when system is gone out screen time T to causing mobile terminal 100 screen that automatically goes out.
Fig. 4 is the preferred flow charts of the method for dynamic adjustments range sensor threshold value of the present invention, and it can be realized by mobile terminal 100 as shown in Figure 2, comprises that step has:
Step S401, opens range sensor and converses.
Step S402, whether judging distance transducer detects near state, if perform step S403, otherwise execution step S404.In the present embodiment, described range sensor is that light value detects range sensor.
Step S403, if detect near state, directly switches to screen to go out screen state and exit flow process from bright screen state.
Step S404, if do not detect near state, the system of first acquisition system of the system setting screen time T (for example 15 seconds) of going out, is divided into N grade (for example N=3) by the system screen time T of going out, increase timer, and setting timer when T/N is triggered; Variable i is set to judge whether to reach automatic adjusting threshold number, the initial value of variable i is 0; Interval threshold M (for example M=50) is set, to guarantee that the upper limit light threshold value after adjusting must be greater than M values of light of lower limit light threshold value, described upper limit light threshold value is corresponding to state, described lower limit light threshold value correspondence is away from state, but need there is certain intervals threshold value M between upper limit light threshold value and lower limit light threshold value, otherwise can near state and away from the critical point of state on stable not, to meet the object of range sensor operation principle.The upper limit threshold that the upper limit light threshold value of adjusting is acquiescence: current_hi_threshold=hi_threshold is set during beginning.
Step S405, when i T/N arrives constantly, (when i rank arrives) triggers timer, carry out timing function, i=i+1 is set in timing function, and will apart from corresponding upper limit light threshold value, reduce predetermined value or predetermined ratio near state-detection, current_hi_threshold=(1-X%) current_hi_threshold for example, regulates upper limit light threshold value to make it to reduce X% (for example 5%).
Step S406, whether judgement (i <=n & & current_hi_threshold > low_thresldhold+M) sets up simultaneously, judge whether the upper limit light threshold value after i <=N and adjusting can be set up above than the predetermined large M of lower limit light threshold value simultaneously, if set up and perform step S407 simultaneously, otherwise execution step S408.
Step S407, according to the upper limit light threshold value after regulating, whether judging distance transducer detects near state, if detect near state and perform step S409, otherwise turn back to step S405, carry out the dynamic adjustments threshold value of i+1 time, until (i <=n & & current_hi_threshold > low_thresldhold+M) is the false flow process that just exits.
Step S408, if system is gone out, screen time T does not detect yet near state after arriving, and screen is switched to the screen state that goes out to save power consumption from bright screen state, and finishes whole flow process.After representing the i time (i is the last number of times that regulates threshold value) adjusting threshold value, range sensor still detects away from state, and when call is described, range sensor is not near head.Automatically time is up can cause the mobile terminal screen that automatically goes out for the screen that goes out of now system setting.
Step S409, if detect near state after regulating near state-detection distance, switches to from bright screen state the screen state that goes out by screen.Now, represent that range sensor has made the mobile terminal screen that goes out, and now can produce near interruption.
Step S410, cancel timer, thereby and call the flow process that upper limit light threshold value that range calibration interface is made as acquiescence by the upper limit light threshold value after current adjusting completes whole dynamic adjustments threshold value, to guarantee the reliability of range sensor, be the calibration that range sensor re-starts upper limit threshold, with amended upper limit light threshold value, detect in the future.
Step S411, after talk-through, whether judging distance transducer detects away from state, if perform step S412, otherwise continues to carry out this step S411.
Step S412, if detect away from state, switches to bright screen state by screen from the screen state that goes out, and user can normally use mobile terminal 100 again like this.
In sum, the present invention is by dynamic adjustments range sensor threshold value, in system is gone out screen time T, the close state-detection distance of range sensor is at least increased to predetermined value or predetermined ratio, to be more prone to detect near state, thereby avoid mobile terminal when call range sensor undetected near state, the mobile terminal problem of bright screen automatically after the talk-through causing.Whereby, mobile terminal of the present invention can increase because detecting near automatically the go out possibility of screen of state in when call, and therefore, when talk-through and mobile terminal leave head, mobile terminal still can be realized automatic bright screen, thereby greatly facilitates user's use.
