For the technical scheme of description the embodiment of the present application become apparent from, with reference to Fig. 2, the embodiment of the present application is carried A kind of flow of the backlight adjusting method supplied is described.Wherein, methods described is applied to that there is each electron-like of display screen to set In standby, wherein, processor, ambient light sensor and backlight drive IC are included in the electronic equipment.The electronic equipment can be with For mobile phone 100 as shown in Figure 1.As shown in fig.2, the handling process of this method includes：
Step 201：The processor obtains multiple first intensity of illumination sampled values.
In the embodiment of the present application, the unit of the intensity of illumination sampled value is lux (Lux), the list of backlight brightness values Position is candela/square metre (cd/m2)。
Optionally, after the processor can be with normal operation, or display content on the display screen of the determination electronic equipment When (non-dark screen state), or when the electronic equipment determines that the ambient light of itself local environment changes, or it is described When processor receives the backlight regulating command of user's input, the step 201 is performed.
Wherein, to be the processor carried out to the LCD backlight regulation of the multiple first intensity of illumination sampled value according to According to.
Because the ambient light sensor of the electronic equipment can gather the electronics and set according to traditional sample frequency The intensity of illumination of ambient light in standby current usage scenario environment, obtains multiple intensity of illumination sampled values.
Optionally, the processor in the electronic equipment can obtain the multiple first illumination by three kinds of modes Intensity samples values：
First way：The processor receives the intensity of illumination sampled value that the ambient light sensor is sent and directly made The foundation adjusted by the use of these sampled values as backlight.
The second way：The processor receives multiple intensity of illumination sampled values that the ambient light sensor is sent；And According to the intensity of illumination sampled value of historical reception, the illumination of insertion setting number is strong in two adjacent intensity of illumination sampled values Sampled value is spent, generates the multiple first intensity of illumination sampled value.
For example, the processor inserts intensity of illumination in the 1st intensity of illumination sampled value and the 2nd intensity of illumination sampled value During sampled value, the processor history intensity of illumination sampled value that within a specified time (such as 10 seconds before current time) receive In, search two history intensities of illumination that value is equal to the 1st intensity of illumination sampled value and the 2nd intensity of illumination sampled value Sampled value, and the history intensity of illumination sampled value for setting number is filtered out in two history intensity of illumination sampled values, it is inserted into In the 1st intensity of illumination sampled value and the 2nd intensity of illumination sampled value.
The third mode：Enter in the intensity of illumination sampled value that the processor needs to send the ambient light sensor of reception Row filtration treatment using finite impulse response (Finite Impulse Response, FIR) wave filter (for example, carried out at filtering Reason) in the case of, the computing device step 201 comprises the following steps：
The processor receives m currently transmitted intensity of illumination sampled value of ambient light sensor, and m is just whole more than 2 Number；
The processor performs following steps to k-th of intensity of illumination sampled value in the m intensity of illumination sampled value, its In, k is taken all over all positive integers for being less than or equal to m：
The processor is according to the filter value of k-th of intensity of illumination sampled value top n intensity of illumination sampled value, in institute State the interpolation of insertion setting number between k-th of intensity of illumination sampled value and the k+1 intensity of illumination sampled value；And by described in K-th of intensity of illumination sampled value and the interpolation carry out filtration treatment, generate in the multiple first intensity of illumination sampled value One the first intensity of illumination sampled value, wherein, N is positive integer；
The processor is realized to strong per two neighboring illumination in the m intensity of illumination sampled value by above-mentioned steps Insertion sets the intensity of illumination difference of number between spending sampled value, and carries out filtration treatment, and it is strong to generate the multiple first illumination Spend sampled value.
Wherein, in above-mentioned steps, the intensity of illumination difference of the setting number is identical, and the illumination of the setting number Intensity interpolation meets below equation：
Wherein, finterpAny of intensity of illumination interpolation for setting number intensity of illumination difference；P (j) is described The filter value of j-th of intensity of illumination sampled value before k-th of intensity of illumination sampled value；Q (k) samples for k-th of intensity of illumination Value；R is the weight of the Q (k),A is default fixed empirical value, and Δ d samples for k-th of intensity of illumination Difference between value and the k+1 intensity of illumination sampled value, n are statistical value, and n initial value is 1, is adopted in current light intensity When the difference of the filter value of sample value and previous intensity of illumination sampled value is less than preset range, n adds 1, until n equal to it is default most N reverts to initial value after big value.
In the first way, it is strong can directly to obtain multiple illumination that the ambient light sensor gathers for the processor Sampled value is spent, and backlight regulation is performed to the LCD according to the multiple intensity of illumination sampled value.Accordingly, with respect to traditional Step backlight adjusting method, the backlight regulation of the electronic equipment is relatively more timely and precision is higher, saves the electronics and sets Standby power consumption, and ensure that the constant visibility of user.
Because the sample frequency of the intensity of illumination of traditional ambient light sensor collection is relatively low (such as 6 hertz (Hz)), because This, multiple intensity of illumination sampled values of ambient light sensor collection can not embody that the electronic equipment is current to be made completely With the change of the ambient light in scene environment, therefore, when the processor uses first way, directly according to acquisition When multiple intensity of illumination sampled values of ambient light sensor collection carry out backlight regulation to the display screen, it is possible to cause in root During wherein certain two intensity of illumination sampled value carries out backlight regulation, the ambient light of the electronic equipment local environment Changed, cause the electronic equipment backlight regulating effect be not reaching to it is optimal.
Based on above description, the processor can use the above-mentioned second way, get the ambient light sensing After multiple intensity of illumination sampled values of device collection, according to the intensity of illumination sampled value of historical reception, to the multiple intensity of illumination Sampled value enters row interpolation, the intensity of illumination sampled value of insertion is met the intensity of illumination variation tendency of ambient light, so as to improve To the sample frequency of the intensity of illumination of ambient light.Accordingly, with respect to first way, the processor can using the second way To ensure that backlight regulation that the electronics sets more meets the intensity of illumination variation tendency of the electronic equipment local environment, make institute It is more preferable to state the backlight regulating effect of electronic equipment, improves Consumer's Experience.
In the second way, it is described setting number can according to residing for the electronic equipment specific application environment or use Family input is configured, and the setting number can be 3,4 etc..For example, when the intensity of illumination of ambient light sensor collection Sample frequency when being 6Hz, and the number that sets is 3, due to 6* (3+1)=24 (Hz), then the processor, which passes through, to be inserted The sample frequency for entering the multiple first intensity of illumination sampled value of sampled value generation is changed into 24Hz.
In the third mode, because the processor needs to adopt multiple intensities of illumination of reception by FIR filter Sample value carries out filtration treatment, but the performance characteristics of the FIR filter are：The length that is delayed and exponent number are proportional, and intermediate zone It is in inverse ratio with exponent number, therefore, considers delay performance requirement and the filter bag of the FIR filter, the FIR filter Exponent number can only compromise selection.When the exponent number of the FIR filter is fixed, the sample frequency of the ambient light sensor is too low, Also the delay performance requirement of the FIR filter can not be ensured, therefore, it is necessary to improve the sampling frequency of the ambient light sensor Rate.By the third mode, the processor is in the m intensity of illumination sampled value per two neighboring intensity of illumination sampled value Between insertion setting number X intensity of illumination difference, the sample frequency of intensity of illumination sampled value is improved X+1 times, so, can To ensure the delay performance of the FIR filter.
In the third mode, the processor is to the k intensity of illumination sampled value and the k+1 intensity of illumination During entering row interpolation between sampled value, the processor is realized and the top n intensity of illumination is sampled by above-mentioned formula The filter value of value is compared with k-th of intensity of illumination sampled value, so as to judge k-th of intensity of illumination sampled value Belong to the probability of noise, and embody k-th of belonging to for intensity of illumination sampled value by setting the size of weight and make an uproar The probability of sound：When the weight of k-th of intensity of illumination sampled value is larger, k-th of intensity of illumination sampled value category is represented It is smaller in the probability of noise；When the weight of k-th of intensity of illumination sampled value is smaller, k-th of intensity of illumination is represented The probability that sampled value belongs to noise is larger.By the above method, the processor can ensure the intensity of illumination difference symbol determined Close the intensity of illumination of actual environment light.
In aforesaid way, the processor is filtered processing using FIR filter, and is filtered by adjusting the FIR The performance parameters such as exponent number, cut-off frequency and the attenuation degree of ripple device, filter out multiple illumination that the ambient light sensor is sent The noises such as burr, shake in intensity samples values.It is the multiple after the filtering of the characteristics such as the high-fidelity using the FIR filter First intensity of illumination sampled value can embody the intensity of illumination variation tendency of the electronic equipment local environment without distortion, can It is right to ensure that the follow-up processor in subsequent step is the intensity of illumination variation tendency based on the electronic equipment local environment The display screen carries out backlight regulation, improves the backlight degree of regulation of the electronic equipment, and then also improve user's body Test.
Step 202：The processor carries out identical processing to each first intensity of illumination sampled value successively, wherein, institute State processor includes to the processing step of any one the first intensity of illumination sampled value：A. the processor is according to intensity of illumination and the back of the body In the corresponding relation of brightness values, target backlight luminance value corresponding to the first intensity of illumination sampled value is determined；B. the place Reason device is adjusted by n backlight, by the backlight illumination of display screen from the initial backlight brightness value regulation at current time to the mesh Backlight brightness values are marked, wherein, n is positive integer.
The processor can also obtain the data of other sensors, such as proximity transducer before step 202 is performed Data.When the processor determines by the data of the proximity transducer ambient light sensor of the electronic equipment When covering situation be present, the processor continues executing with step 202, this way it is possible to avoid because user or other objects hide The ambient light sensor is covered, causes backlight mistuning of the processor to the display screen.
Optionally, the processor to any one first intensity of illumination sampled value carry out above-mentioned steps a and step b it Before, in addition to, determine that the first intensity of illumination sampled value is different from a upper first intensity of illumination sampled value.
In step 202, the processor is for each or almost each first intensity of illumination sampled value is performed both by backlight Brightness regulation, and be that target backlight luminance value carries out backlight illumination regulation according to corresponding to each first intensity of illumination sampled value , therefore, the backlight regulation of the electronic equipment is relatively more timely and precision is higher, saves the power consumption of the electronic equipment.
In step a, the corresponding relation of intensity of illumination and backlight brightness values is stored with the processor, it is therefore, described Processor can be according to the corresponding relation, it is determined that target backlight luminance value corresponding to each first intensity of illumination sampled value.
Optionally, the processor is when performing step b, including：
The processor is adjusted for each backlight in n backlight regulation, determines the first backlight brightness values, described First backlight brightness values are backlight brightness values of display screen at the time of this backlight is adjusted, and according to first backlight Brightness value and human eye sensitivity's information (such as human eye sensitivity's curve) of storage, it is determined that the backlight regulation step of this described backlight regulation It is long, wherein, human eye sensitivity's information represents the corresponding relation of backlight brightness values and unaware backlight regulation step-length, described noninductive Know that backlight regulation step-length represents that the display screen is perceived less than in the case of in corresponding backlight brightness values and human eye, the display The maximum backlight illumination changing value of screen；
The processor adjusts step-length according to first backlight brightness values and the backlight, determine the display screen this The second backlight brightness values after regulation；
Second backlight brightness values are sent to the backlight drive IC by the processor.
Fig. 3 shows a kind of possible human eye sensitivity's curve under normal office work environment, the invention relates to Human eye sensitivity's curve is not limited to human eye sensitivity's curve shown in Fig. 3.
In the above-mentioned methods, the processor is to utilize human eye sensitivity's information, it is determined that the backlight regulation of backlight regulation every time Step-length, the processor is set to realize user's human eye unaware when each backlight is adjusted, ensure that Consumer's Experience.
Optionally, in the above-mentioned methods, the processor is bent according to first backlight brightness values and the human eye sensitivity Line, the backlight regulation step-length is determined, including：
The processor determines unaware backlight corresponding to first backlight brightness values in human eye sensitivity's information Step-length is adjusted, still by taking human eye sensitivity's curve shown in Fig. 3 as an example, when first backlight brightness values are 2000, corresponding nothing It is 7.5 to perceive backlight regulation step-length；
The processor adjusts step-length according to the unaware backlight and determines that the backlight adjusts step-length.
By the above method, the first backlight illumination of the display screen at the time of processor is adjusted according to this backlight Value and human eye sensitivity's information, it is determined that the unaware backlight that backlight is adjusted when the display screen is in the backlight brightness values is adjusted Step-length is saved, and step-length is adjusted according to the unaware and determines that the backlight adjusts step-length.So, the processor described will show The backlight illumination of display screen from first backlight brightness values adjust the backlight regulation step-length when, it is ensured that the human eye of user is not The backlight illumination change of the display screen can be substantially perceived, improves the experience of user.
For example, in the case where gradual change occurs for the electronic equipment local environment light, the processor determines each backlight The backlight regulation step-length of regulation is less than or equal to corresponding unaware backlight regulation step-length, and now, the processor is being carried on the back During light is adjusted, the backlight illumination change of the complete unaware display screen of human eye of user.
In another example in the case where the electronic equipment local environment light is undergone mutation, the processor determines each The backlight regulation step-length of backlight regulation makes the processor as soon as possible slightly larger than the corresponding unaware backlight regulation step-length determined Target backlight luminance value is adjusted to, meanwhile, user's human eye is adapted to the change of ambient light as early as possible, now, the processor exists During carrying out backlight regulation, the human eye of user can slightly perceive the backlight illumination change of display screen.
Wherein, in the above-mentioned methods, the processor can use a variety of backlights regulation strategy, be carried on the back according to the unaware Light regulation step-length determines the backlight regulation step-length, for example, adjusting step-length, and the initial back of the body according to the unaware backlight Brightness values and the target backlight luminance value, determine the backlight regulation step-length.
For example, when the difference between the initial backlight brightness value and the target backlight luminance value is larger, the place Reason device can also suitably increase on the basis of the unaware adjusts step-length, the backlight regulation step-length be obtained, so that described Display screen regulation faster can be arrived the target backlight luminance value by processor；When the initial backlight brightness value and When difference between the target backlight luminance value is smaller, the unaware is adjusted step-length and (or is slightly less than institute by the processor State the step-length of unaware regulation step-length) final backlight regulation step-length is adjusted as this backlight.But the processor In be provided with the scope (i.e. setting value) of unaware regulation step-length increase, avoid the backlight from adjusting step-length value excessive, Cause backlight adjust during the display screen backlight illumination change it is excessively obvious, user's human eye also can substantially perceive backlight Brightness changes, and reduces the experience of user.
From the above description, it can be seen that the backlight regulation step-length is less than or equal to backlight regulation step-length threshold value, the backlight It is that the unaware adjusts step-length and the setting value sum to adjust step-length threshold value.So, the processor is according to the back of the body During light regulation step-length carries out backlight regulation, the backlight illumination change of the display screen can not substantially be perceived by ensureing the human eye of user Change, and display screen regulation faster can be arrived into the target backlight luminance value.
Specifically, the processor when performing step b, is entered according to the high frequency regulating frequency (such as 1000Hz) of setting The row n backlight regulation, in this manner it is ensured that during the processor frequently carries out backlight regulation, accomplish people Eye unaware.
When the processor of the electronic equipment not only includes AP, also comprising coprocessor when, optionally, the embodiment of the present application The processor for the execution backlight regulation being related to can be the coprocessor of the electronic equipment.
In order to realize the above method, there is one on hardware, between the coprocessor and the backlight drive IC specially There is passage, ensure that the coprocessor can directly access the backlight drive IC, needed in the coprocessor to described When display screen carries out backlight regulation, the backlight of the display screen can be adjusted by above-mentioned passage complete independently.On software, The electronic equipment uses autonomous system (Standalong) framework, i.e. AP described in backlight regulation process is not involved in, but by institute Coprocessor complete independently is stated, therefore, during backlight regulation, greatly reduces the coprocessor and the AP interaction Frequency, and reduce and the problem of backlight regulation causes power consumption larger is performed by the AP.
Using backlight adjusting method provided in an embodiment of the present invention, processor obtains multiple first intensity of illumination sampled values Afterwards, following backlight illumination regulating step is performed to each first intensity of illumination sampled value successively：Processor described first is according to light According to the corresponding relation of intensity and backlight brightness values, target backlight luminance value corresponding to the first intensity of illumination sampled value is determined；So The processor is adjusted by multiple backlight afterwards, and the backlight illumination of display screen is adjusted from the initial backlight brightness value at current time To the target backlight luminance value.Because, the processor is for each or almost each first intensity of illumination sampled value is held Row backlight illumination is adjusted, and is that target backlight luminance value carries out backlight illumination tune according to corresponding to the first intensity of illumination sampled value Section, therefore, the backlight regulation of the electronic equipment is relatively more timely and precision is higher, saves the power consumption of the electronic equipment, And it ensure that the constant visibility of user.

Similarly, the processor is determined in second intensity of illumination sampled value 300 and the 3rd intensity of illumination sampled value 300 3 intensity of illumination interpolation be 300, and then by the second intensity of illumination sampled value and obtained 3 intensity of illumination interpolation One the first intensity of illumination sampled value 300 is filtrated to get by FIR filter；
Similarly, the processor is determined between the 3rd intensity of illumination sampled value 300 and the 4th intensity of illumination sampled value 0 Intensity of illumination interpolation be 240, and then the 3rd intensity of illumination sampled value and obtained 3 intensity of illumination interpolation are passed through FIR filter is filtrated to get a first intensity of illumination sampled value 235；
Similarly, the processor is determined between the 4th intensity of illumination sampled value 0 and the 5th intensity of illumination sampled value 0 Intensity of illumination interpolation is 130, and then the 4th intensity of illumination sampled value and 3 obtained intensity of illumination interpolation is passed through FIR filter is filtrated to get a first intensity of illumination sampled value 127；
Similarly, the processor determine the 5th intensity of illumination sampled value 0 and the 6th intensity of illumination sampled value 0 it Between intensity of illumination interpolation be 22, and then the 5th intensity of illumination sampled value and obtained 3 intensity of illumination interpolation are led to Cross FIR filter and be filtrated to get a first intensity of illumination sampled value 20；
Similarly, the processor determine the 6th intensity of illumination sampled value 0 and the 7th intensity of illumination sampled value 0 it Between intensity of illumination interpolation be 3, and then look after intensity samples values by described 6th and obtained 3 intensity of illumination interpolation pass through FIR filter is filtrated to get a first intensity of illumination sampled value as 0；
The first intensity of illumination sampled value that the follow-up processor obtains is 0.
By discussed above, the multiple intensity of illumination that the processor is sent according to the ambient light sensor The first intensity of illumination sampled value that sampled value obtains is 300,300,235,127,20,0,0 ...
The display is in the process for carrying out backlight regulation for the 3rd the first intensity of illumination sampled value 235：
The processor determines target corresponding to 235 according in the corresponding relation of the intensity of illumination and backlight brightness values Backlight brightness values are 1500, and now the initial backlight brightness value of the display screen is 1900, bent by the human eye sensitivity shown in Fig. 3 Line understands that unaware backlight regulation step-length is 7 corresponding to backlight brightness values 1900, and therefore, the processor is by first time backlight The backlight brightness values (1900-7=1893) of regulation are sent to the backlight drive IC of the electronic equipment, so that the backlight drive The backlight illumination of the display screen is adjusted to 1893 by IC；The processor continues through human eye sensitivity's curve and understands that backlight is bright Unaware backlight regulation step-length is 6.9 corresponding to angle value 1983, and therefore, the backlight that the processor adjusts second of backlight is bright Angle value (1893-6.9=1886.1) is sent to the backlight drive IC, so that the backlight drive IC is by the back of the body of the display screen Brightness is adjusted to 1886.1；So repeatedly, until the backlight illumination of the display screen is adjusted to 1500 by the processor.
