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 portable terminal 100 as shown in Figure 2, comprise that step has:
Step S401 opens range sensor and converses.
Whether step S402, judging distance transducer detect near state, if execution in step S403 then, otherwise execution in step S404.In the present embodiment, described range sensor is that light value detects range sensor.
Step S403 if detect near state, then directly switches to screen and goes out the screen state and withdraw from flow process from the bright screen state.
Step S404, if do not detect near state, the system of at 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) with system's 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 the 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 between upper limit light threshold value and the lower limit light threshold value certain intervals threshold value M need be arranged, otherwise can near state and away from the critical point of state on stable not, to meet the purpose of range sensor operation principle.The upper limit light threshold value of adjusting is set during beginning is the upper limit threshold of acquiescence: current_hi_threshold=hi_threshold.
Step S405, (when i rank arrives) triggers timer when i T/N arrives constantly, carry out timing function, i=i+1 is set in timing function, and will be near upper limit light threshold value minimizing predetermined value or the predetermined ratio of state-detection apart from correspondence, current_hi_threshold=(1-X%) current_hi_threshold for example namely regulates upper limit light threshold value and makes it to reduce X% (for example 5%).
Step S406 judges (i＜=n﹠amp; ﹠amp; Current_hi_threshold＞low_thresldhold+M) whether set up simultaneously, namely judge i＜=N and regulate after the predetermined large M of lower limit light threshold value of upper limit light threshold ratio more than whether can set up simultaneously, if set up simultaneously then execution in step S407, otherwise execution in step S408.
Step S407, according to the upper limit light threshold value after regulating, whether the judging distance transducer detects near state, if detect then execution in step S409 of close state, otherwise turn back to step S405, carry out i+1 time dynamic adjustments threshold value, until (i＜=n﹠amp; ﹠amp; Current_hi_threshold＞low_thresldhold+M) is the false flow process that just withdraws from.
Step S408 does not detect yet near state after the screen time T arrives if system goes out, and then screen is switched to the screen state that goes out with the saving power consumption from the bright screen state, and finishes whole flow process.Represent the i time (i is the last number of times of regulating threshold value) regulate threshold value after range sensor still detect away from state the not close head of range sensor when conversation be described.Automatically time is up can cause the portable terminal screen that automatically goes out for the screen that goes out of system setting this moment.
Step S409 if detect near state, then switches to the screen state that goes out with screen from the bright screen state after regulating near the state-detection distance.At this moment, the expression range sensor is the screen so that portable terminal goes out, can produce this moment near interrupting.
Step S410, the cancellation timer, thereby and call the flow process that upper limit light threshold value that the upper limit light threshold value of range calibration interface after with current adjusting be made as acquiescence is finished whole dynamic adjustments threshold value, to guarantee the reliability of range sensor, be the calibration that range sensor re-starts upper limit threshold, detect with amended upper limit light threshold value in the future.
Step S411, behind talk-through, whether the judging distance transducer detects away from state, if execution in step S412 then, otherwise continue to carry out this step S411.
Step S412 if detect away from state, then switches to the bright screen state with screen from the screen state that goes out, and the user can normally use portable terminal 100 again like this.
In sum, the present invention is by dynamic adjustments range sensor threshold value, namely in the screen time T is gone out in system, the close state-detection distance of range sensor is increased predetermined value or predetermined ratio at least, in order to be more prone to detect near state, thereby avoid portable terminal when conversation range sensor undetected near state, the automatic problem of bright screen of portable terminal behind the talk-through that causes.Whereby, portable terminal of the present invention can increase because detecting near automatically the go out possibility of screen of state in when conversation, and therefore when talk-through and portable terminal left head, portable terminal still can be realized automatic bright screen, thereby greatly facilitates user's use.
