Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First execution mode of the present invention relates to a kind of threshold value calibration steps of range sensor.In actual applications, the present inventor finds, because the spot on touch-screen can the light leak etc. of reflecting part infrared ray and internal structure of mobile phone, the value of reading of range sensor is made up of two parts, i.e. the infrared ray value of reflective surface and light leak value.The mobile phone light leak value of different structure is different, mobile phone in use because of falling physically, to rub and the reason such as spot also can cause the light leak value of mobile phone to change, and the difference of light leak value must cause the change of high and low threshold value, therefore, by changeless for high and low threshold value way in prior art, can cause range sensor read value for high and low threshold value time, the actual position of reflecting surface has deviation with position when setting this value at that time, likely causes mobile phone cannot the normal bust that shields of light on and off.Based on this discovery, present embodiment, when range sensor is started working, by the light leak value of Real-time Obtaining current distance transducer, and the high and low threshold value of current distance transducer is upgraded according to the light leak value of current distance transducer, not only increase the accuracy of the high and low threshold value of current distance transducer, also improve the performance of mobile phone, thus bring better experience to user.
The idiographic flow of present embodiment as shown in Figure 2.
In step 201, whether terminal judges is being dialed or is being received calls.If so, then step 202 is entered, if not, then return this step.
In step 202., the range sensor of terminal is started working, and terminal obtains the light leak value of current distance transducer.
The process of the light leak value how terminal being obtained to current distance transducer is done concrete elaboration below.
As shown in Figure 3, in step 301, the maximum displacement value that range sensor can read by terminal as the initial value of range sensor, and enters step 302.
In step 302, reading value and whether being less than initial value of terminal judges current distance transducer, if so, then enters step 303, if not, then return this step.
In step 303, what the initial value of displacement sensor was updated to current distance transducer by terminal reads value, and using the light leak value of the initial value after upgrading as current distance transducer.
It should be noted that, the range sensor of terminal starts dialing user, or when starting to connect phone, namely start working, now terminal have one from away from head (user just dialing or just started to answer the call time) to the process of close head (carrying out the process conversed), when terminal is away from head, owing to there is no reflecting surface, be not difficult to find, now range sensor read to be worth the light leak value being current distance transducer, simultaneously, from range sensor to read to be worth be infrared ray value and light leak value two parts sum of reflective surface, now range sensor to read value minimum, therefore, in general, in the process of terminal away from head, just can obtain the light leak value of current distance transducer.
In step 202., after getting the light leak value of current distance transducer, then step 203 is entered.
In step 203, terminal is according to the light leak value of the current distance transducer got, and preset the first deviate in the terminal and the second deviate, the Low threshold of current distance transducer is updated to the light leak value sum of the first deviate and current distance transducer, the high threshold of current distance transducer is updated to the light leak value sum of the second deviate and current distance transducer.
Wherein, the difference reading the light leak value of value and this range sensor of the first deviate is the screen distance reflecting surface of terminal when being the first predeterminable range range sensor; The difference reading the light leak value of value and this range sensor of the second deviate is the screen distance reflecting surface of terminal when being the second predeterminable range range sensor; Further, the first predeterminable range is less than the second predeterminable range.
Be specifically addressed to the set-up mode of the first deviate and the second deviate below.
As shown in Figure 4, in step 401, N number of test terminal (as mobile phone) is placed in flat condition; Wherein, the surface at the screen place of N number of test terminal is not all blocked, N be more than or equal to 1 natural number; Present embodiment is specifically addressed equaling 10 for N the set-up mode of the first deviate and the second deviate, and meanwhile, conveniently manage, 10 test terminal number consecutivelies are 0 to 9 by present embodiment.
In step 402, what obtain 10 test terminal current distance transducers reads value, be not difficult to find, because the surface at screen place, current 10 test terminals is not all blocked, namely now all there is not reflecting surface in 10 test terminals, therefore current each test terminal range sensor read to be worth the light leak value being this range sensor.
As described in step 401, for the ease of management, the light leak value MIN_VAL of 10 test terminals will got in this step
xrepresent, wherein, x represents the numbering of each test terminal, and desirable 0 to 9, such as, when x gets 0, MIN_VAL
xrepresent the light leak value being numbered the test terminal of 0; When x gets 5, MIN_VAL
xthen represent the light leak value being numbered the test terminal of 5.
In step 403, when the screen distance reflecting surface obtaining each test terminal is the first predeterminable range, range sensor reads value LOW_VAL
x(this place and the x hereinafter mentioned all identical with the x meaning mentioned in step 402).This enforcement equals 3 centimeters for the first predeterminable range and is described.
For above-mentioned case, when x gets 0, LOW_VAL
xwhen representing that the screen distance reflecting surface being numbered the test terminal of 0 is 3 centimeters this test terminal range sensor read value; When x gets 5, LOW_VAL
xwhen representing that the screen distance reflecting surface being numbered the test terminal of 5 is 3 centimeters this test terminal range sensor read value.
In step 404, when the screen distance reflecting surface obtaining each test terminal is the second predeterminable range, range sensor reads value HIGH_VAL
x.Present embodiment equals 5 centimeters for the second predeterminable range and is described.
Similar, for above-mentioned case, when x gets 0, HIGH_VAL
xwhen representing that the screen distance reflecting surface being numbered the test terminal of 0 is 5 centimeters this test terminal range sensor read value; When x gets 5, HIGH_VAL
xwhen representing that the screen distance reflecting surface being numbered the test terminal of 5 is 5 centimeters this test terminal range sensor read value.
It is worth mentioning that, present embodiment is that range sensor when to obtain the screen distance reflecting surface of each test terminal be the first predeterminable range read value LOW_VAL
x, when to be placed on the screen distance reflecting surface obtaining each test terminal be the second predeterminable range, range sensor reads value HIGH_VAL
xstep before be described for example, but in actual applications, also first can perform step 404, then perform step 403.
In step 405, according to the MIN_VAL of each test terminal range sensor got
x, LOW_VAL
xand HIGH_VAL
x, obtain the LOW_VAL of each test terminal range sensor respectively
xwith MIN_VAL
xdifference LOW_OFFSET
xthe difference reading the light leak value of value and range sensor of range sensor (when namely the screen distance reflecting surface of each test terminal is the first predeterminable range), and the HIGH_VAL of each test terminal
xwith MIN_VAL
xdifference HIGH_OFFSET
xthe difference reading the light leak value of value and range sensor of range sensor (when namely the screen distance reflecting surface of each test terminal is the second predeterminable range).
Conveniently manage, the difference LOW_OFFSET reading the light leak value of value and range sensor of range sensor when being the first predeterminable range by the screen distance reflecting surface of each test terminal in present embodiment
xas the first threshold of each test terminal, and the difference HIGH_OFFSET reading the light leak value of value and range sensor of range sensor when being the second predeterminable range by the screen distance reflecting surface of each test terminal
xas the Second Threshold of each test terminal.
In a step 406, obtain the mean value of 10 test terminal first thresholds, and the mean value of Second Threshold is (namely according to the LOW_OFFSET of each test terminal got
xand HIGH_OFFSET
x, obtain the LOW_OFFSET of 10 test terminals
xmean value, and the HIGH_OFFSET of 10 test terminals
xmean value).
In step 407, the difference reading the light leak value of value and this range sensor of range sensor when being the first predeterminable range using the mean value of first threshold as the screen distance reflecting surface of terminal (terminal mentioned in step 201), when being the second predeterminable range using the mean value of Second Threshold as the screen distance reflecting surface of terminal, the difference reading the light leak value of value and this range sensor of range sensor is (by the LOW_OFFSET of 10 test terminals
xmean value as the first deviate, by the HIGH_OFFSET of 10 test terminals
xmean value as the second deviate).
It is worth mentioning that, the structure of 10 test terminals mentioned in step 401 to step 407 is identical with the structure of the terminal mentioned in step 203 (as mobile phone).
The acquisition of the first deviate and the second deviate carries out in the development of terminal, after getting the first deviate and the second deviate, present embodiment is preset in the terminal, for terminal dynamic calibration for high and low threshold value in the use procedure in later stage.
After the high and low threshold value of current distance transducer is updated successfully, then enter step 204.
In step 204, the reading of terminal judges current distance transducer is worth the high threshold whether being greater than current distance transducer, if, then enter step 205, and in step 205, extinguish the background light (current distance transducer read value when being greater than high threshold, the process how terminal extinguishes the background light of screen is prior art, and present embodiment repeats no more) of screen; If not, then enter step 206.
In step 206, the reading of terminal judges current distance transducer is worth the Low threshold whether being less than current distance transducer, if, then enter step 207, and in step 207, light screen background light (current distance transducer read value when being less than Low threshold, the process how terminal lights the background light of screen is prior art, present embodiment repeats no more), if not, then return step 204.
The step of various method divides above, just in order to be described clearly, can merge into a step or splitting some step, being decomposed into multiple step, when realizing as long as comprise identical logical relation, all in the protection range of this patent; To adding inessential amendment in algorithm or in flow process or introducing inessential design, but the core design not changing its algorithm and flow process is all in the protection range of this patent.
