The calibration method of proximity sensor in the embodiment of the present application is described based on above-mentioned electronic equipment 10.
Referring to Fig. 2, Fig. 2 is the flow diagram of the calibration method of proximity sensor in the embodiment of the present application, this implementation
In example, the calibration method of above-mentioned proximity sensor includes:
Step 201, the electronic equipment be in breath screen state when, obtain the light that the environment photosensitive sensors detect
Intensity value.
Proximity sensor can be a variety of different types of proximity sensors, commonly can be infrared proximity transducer,
By taking infrared proximity transducer as an example, infrared proximity transducer can emit infrared ray to touch panel direction, and it is anti-then to measure object
It is emitted back towards the infra-red intensity come and comes the distance between judgment object and infrared proximity transducer, the infra-red intensity received is got over
By force, then it represents that the distance between itself and object are smaller.Infrared proximity transducer can convert the infra-red intensity measured to
The measured value of its proportional, the measured value are properly termed as proximity values, and the proximity values that infrared proximity transducer obtains are bigger,
Indicate that the distance between itself and object are smaller.
In general, the proximity values that proximity sensor measures can determine that it is proximity state or separate shape between object
State, and the judgement of the state when proximity values are greater than close to threshold value, is then can determine based on being determined close to threshold value
Proximity state between proximity sensor and object, when proximity values are less than close to threshold value, can determine proximity sensor with
It is far from state between object.
Wherein, when proximity sensor is arranged in below the touch screen of mobile terminal, bottom will be generated and made an uproar value, wherein bottom is made an uproar value
When any object is not present for the top of touch display screen, light is detected in mobile terminal internal diffraction and by proximity sensor
Signal value, the bottom of referred to as proximity sensor are made an uproar value.
Currently, shielding the position of lower proximity sensor after pressing electronic equipment screen two sides or electronic equipment are fallen
Setting may change, and the bottom of proximity sensor value of making an uproar is caused to change, thus can cause close to dysfunction, therefore,
Need calibrating close to threshold value to proximity sensor.
It should be noted that if needing to calibrate proximity sensor, then need to be in breath screen state in touch screen, and
It is carried out under conditions of have no occluder above touch screen.Wherein, it needs to be because starting under bright screen state close in breath screen state
When sensor, it may appear that the phenomenon that touch screen flashes, screen flicker will affect the brightness of touch screen, and the variation of brightness, which will affect, to be connect
The collected proximity values of nearly sensor, lead to alignment error.Have no occluder above touch screen is needed, is the variation of the value because bottom is made an uproar
Result in proximity sensor close to dysfunction, therefore, if desired calibrated to close to threshold value, need to measure true
Bottom make an uproar value.
Wherein it is possible to preset a calibration cycle in the electronic device, i.e., judgement at regular intervals is once close to sensing
Whether device, which needs, is calibrated, if it is determined that is needed to calibrate proximity sensor, is then touched by ambient light sensor detection aobvious
Light intensity value above display screen.
Step 202, according to the light intensity value, determine the top of the touch display screen with the presence or absence of shelter.
It is understood that when electronic equipment be in breath screen state, and top be not present shelter when, in available light
Under, the light intensity that environment photosensitive sensors receive can be relatively strong, and the light of each region is strong above touch display screen in other words
It spends more uniform；If electronic equipment is in breath screen state, and there are the light that when shelter, environment photosensitive sensors are received for top
If line intensity then can be compared with the light intensity of each region will appear difference above touch display screen in other words.Therefore in the present embodiment,
After the light intensity value that the environment photosensitive sensors got detect, it can be shown according to the light intensity value to determine to touch
The top of display screen whether there is shelter.
Step 203, when shelter is not present in the top of the touch display screen, to the proximity sensor close to door
Limit value is calibrated.
In the present embodiment, when shelter is not present in the top for determining touch display screen, i.e. expression proximity sensor meets
Calibration condition, at this time can calibrating close to threshold value to proximity sensor；When the top for determining touch display screen exists
When shelter, i.e. expression proximity sensor is unsatisfactory for calibration condition, at this time temporarily not to proximity sensor close to threshold value into
Row calibration can wait preset time period, or when next calibration cycle arrives, redefine the top of touch display screen
With the presence or absence of shelter, if there is no shelter, then calibrating close to threshold value to proximity sensor, if there is screening
Block material then waits preset time period again, or waits next calibration cycle, and so on.
The calibration method of proximity sensor provided by the embodiments of the present application, this method are applied to setting below touch display screen
There is the electronic equipment of proximity sensor and ambient light sensor, this method is in the case where ceasing screen state, by utilizing ambient light sensor
The light intensity value detected can effectively judge that the top of touch display screen with the presence or absence of shelter, makes it possible to effective
Determine whether electronic equipment meets the calibration condition to proximity sensor.And breath screen state is in electronic equipment and touches display
Under conditions of the have no occluder of screen top, realizes to the accurate calibration of proximity sensor, can effectively solve the problem that connecing for proximity sensor
The problem of nearly dysfunction.
Based on the above embodiment, the embodiment of the present application provides following several light intensity values according in each region, determines
The top of touch display screen whether there is the mode of shelter.
Specifically, Fig. 3 is the sub-process schematic diagram of the calibration method of proximity sensor in the embodiment of the present application referring to Fig. 3,
In the embodiment of the present application, according to light intensity value in above-mentioned steps 202, determine that the top of touch display screen whether there is shelter,
It specifically includes:
Light intensity value in step 301, each region divided using the touch display screen calculates the first average value, and
Obtain the second average value of the proximity values of the proximity sensor within a preset period of time.
In the present embodiment, in order to when electronic equipment is in breath screen state, it is determined whether need to proximity sensor
Calibrated close to threshold value, the touch display screen of electronic equipment first can be divided into multiple regions, be set in each region
Ambient light sensor is set, then detects the light intensity value in each region respectively by each ambient light sensor.
Specifically, the touch display screen that environment photosensitive sensors detect can be obtained within the same period (such as 1 second)
Light intensity value in each region of division, and every prefixed time interval (such as 0.1 second), obtain a proximity sensor
Proximity values, then calculate the first average value of the light intensity value in each region, and calculate proximity sensor in the above-mentioned period
Second average value of interior proximity values.
Step 302, according to first average value and the second average value, determine whether the top of the touch display screen deposits
In shelter.
It is understood that when electronic equipment be in breath screen state, and top be not present shelter when, in available light
Under, the light intensity that each region that touch display screen divides receives is identical, i.e., the light intensity value in each region can be kept
Unanimously；If electronic equipment is in breath screen state, and there are each regions that when shelter, touch display screen is divided to receive for top
To light intensity then to will appear the light intensity value in difference or each region obviously different from the light intensity value of environment light.
It, can be according in each region after the light intensity value in the touch display screen each region got therefore in the present embodiment
Light intensity value, to determine the top of touch display screen with the presence or absence of shelter.
Specifically, determining that bottom is made an uproar upper limit value using the first average value；Wherein, when the first average value is more than or equal to preset
When intensity threshold, bottom upper limit value of making an uproar is the first upper limit value, and when the first average value is less than intensity threshold, bottom upper limit value of making an uproar is
Second upper limit value, wherein the first upper limit value is greater than the second upper limit value.
It is understood that the proximity values of proximity sensor output, will receive the influence of surrounding environment light, work as ambient enviroment
When the light intensity value of light is bigger, the proximity values exported close to microphone are also bigger.
Therefore in the present embodiment, when above-mentioned first average value is greater than or equal to preset intensity threshold, bottom is made an uproar the upper limit
Value is arranged to a biggish numerical value, is such as determined as the first upper limit value；It, will when above-mentioned first average value is less than intensity threshold
Bottom upper limit value of making an uproar is arranged to a lesser numerical value, is such as determined as the second upper limit value, and the first upper limit value is greater than the second upper limit value.
Wherein, when the top for determining touch display screen whether there is shelter, if above-mentioned second average value is greater than or waits
It makes an uproar upper limit value in above-mentioned bottom, it is determined that there are shelters above touch display screen；If above-mentioned second average value is less than above-mentioned bottom
When upper limit value of making an uproar, it is determined that shelter is not present in the top of touch display screen.
The calibration method of proximity sensor provided by the embodiments of the present application provides a kind of top of determining touch display screen
With the presence or absence of the mode of shelter, specifically include: the light intensity value in each region divided using touch display screen calculates the
One average value, and obtain the second average value of the proximity values of proximity sensor within a preset period of time；According to the first average value and
Second average value determines the top of touch display screen with the presence or absence of shelter, i.e. the present embodiment can be each by touch display screen
Luminous intensity average value in a region and proximity sensor within a preset period of time close to average value, to determine touch display screen
Top whether there is shelter.
It further, is another sub-process of the calibration method of proximity sensor in the embodiment of the present application referring to Fig. 4, Fig. 4
Schematic diagram in the embodiment of the present application, according to light intensity value in above-mentioned steps 202, determines that the top of touch display screen whether there is
Shelter specifically includes:
Step 401, from the light intensity value in each region that touch display screen divides, choose largest light intensity angle value and most
Small light intensity value.
It is understood that when shelter small volume or shelter the top of touch display screen blocked area
When domain is smaller, the light intensity value in touch display screen partial region only will affect, i.e. the top of touch display screen may
Be blocked region and the region that is not blocked are existed simultaneously, can be existed due to being blocked region with the light intensity value in non-occluded area
Apparent difference, therefore largest light intensity angle value and minimum intensity of light angle value can be chosen from the light intensity value in each region, come
It determines above touch display screen with the presence or absence of shelter.
Step 402 presets the first threshold when the difference of the largest light intensity angle value and the minimum intensity of light angle value is greater than or equal to
When value, determine that there are shelters above the touch display screen.
It is understood that above touch display screen, there are shelters, and the shelter has only blocked touch display
When the partial region of screen, the light intensity value being blocked in region and non-occluded area has apparent difference, that is, be blocked region
Light intensity value can be significantly less than the light intensity value in non-occluded area.
Therefore, the present embodiment can be greater than or equal to default first threshold in the difference of largest light intensity angle value and minimum intensity of light angle value
When value, determine that there are shelters above touch display screen.Wherein, it above-mentioned default first preset can be obtained by test of many times
?.
Step 403, when the difference of the largest light intensity angle value and the minimum intensity of light angle value is less than preset first threshold value, really
Shelter is not present in the top of the fixed touch display screen.
Wherein, when shelter is not present in the top of touch display screen, the light intensity value in each region can be kept substantially
Unanimously, i.e., in the light intensity value in each region, largest light intensity angle value is identical as minimum intensity of light angle value or difference very little.
Therefore, the present embodiment can when the difference of largest light intensity angle value and minimum intensity of light angle value is less than preset first threshold value,
Determine that shelter is not present in the top of touch display screen.
The calibration method of proximity sensor provided by the embodiments of the present application provides another and determines touch display screen

It is understood that when shelter small volume or shelter the top of touch display screen blocked area
When domain is smaller, the light intensity value in touch display screen partial region only will affect, i.e. the top of touch display screen may
Be blocked region and the region that is not blocked are existed simultaneously, can be existed due to being blocked region with the light intensity value in non-occluded area
Apparent difference, therefore can be by calculating the variance yields of the light intensity value in each region, to determine above touch display screen
With the presence or absence of shelter.
Step 502, when the variance yields is greater than or equal to default second threshold, determine the top of the touch display screen
There are shelters.
It is understood that above touch display screen, there are shelters, and the shelter has only blocked touch display
When the partial region of screen, the light intensity value being blocked in region and non-occluded area has apparent difference, i.e. touch display screen
Can there are apparent variation or difference between light intensity value in each region.
Therefore, the present embodiment can determine that described touch shows when above-mentioned variance yields is greater than or equal to default second threshold
There are shelters above display screen.Wherein, it above-mentioned default second preset can be obtained by test of many times.
Step 503, when the variance yields is less than default second threshold, determine that the top of the touch display screen is not present
Shelter.
Wherein, when shelter is not present in the top of touch display screen, the luminous intensity in each region is consistent substantially,
Difference between light intensity value i.e. in each region can very little.
Therefore, the present embodiment can determine the touch display screen when above-mentioned variance yields is less than default second threshold
Shelter is not present in top.
The calibration method of proximity sensor provided by the embodiments of the present application, and provide a kind of the upper of determining touch display screen
Side whether there is the mode of shelter, specifically includes: using the light intensity value in each region, calculating the variance yields of luminous intensity；
When the variance yields is greater than or equal to default second threshold, determine that there are shelters above touch display screen；When the variance yields
When less than default second threshold, the top of the touch display screen is determined there is no shelter, i.e. the present embodiment can pass through touching
The variance yields of the light intensity value in display screen each region is touched, to determine the top of touch display screen with the presence or absence of shelter.
It should be noted that the application can be determined using any one mode in three of the above mode and be touched display
The top of screen whether there is shelter.In addition, the mode that combination determines can also be used, that is, adopt in order to improve the accuracy of judgement
With any two ways or two or more modes in three of the above mode, to determine that the top of touch display screen whether there is
Shelter.
In addition, the application can also determine the top of touch display screen with the presence or absence of shelter, example otherwise
Ultrasonic wave is such as emitted to the top of touch display screen by ultrasonic sensor preset in electronic equipment, or is set by electronics
Preset millimeter wave sensor emits millimeter wave to the top of touch display screen in standby, come determine touch display screen top whether
