Fig. 3 is the flow chart that another brightness shown according to an exemplary embodiment determines method.This method can be used
In brightness determining device, as shown in figure 3, the brightness determines that method may include：
In step 301, the first brightness that luminance sensor detects is obtained.
Exemplary, the set-up mode of the luminance sensor can refer to Fig. 2, bright when the display screen of display device shines
Spend the brightness (that is to say the first brightness) of the received light of light receiving surface of the available luminance sensor of determining device, light-receiving
The received light in face includes：The ambient light of the display screen side of light and display device that display screen issues.
In step 302, the luminance area in display screen is determined.
The light that the luminance area in display screen issues can be received by the light receiving surface of luminance sensor, that is to say this
The light that luminance area issues will affect the first brightness of luminance sensor detection, the shape of the luminance area and the light receiving surface
Shape, area and light receiving surface are related at a distance from display screen.Exemplary, the light receiving surface of luminance sensor is on a display screen
Orthographic projection region can be located in the luminance area, the light that other regions on display screen in addition to the luminance area issue
Light receiving surface will not be usually injected, even if the light that other regions issue injects the light receiving surface, which senses brightness
The influence that device detects the first brightness is also smaller.
It is exemplary, according to each position in luminance area at a distance from light receiving surface, luminance area can be divided into n son
Region, n >=1, the light that light receiving surface can be more receive issues away from its closer subregion, and it is less receive away from
The light that its farther away subregion issues.Such as incorporated by reference to Fig. 4 and Fig. 5, n=4, which may include：Center sub-district
Domain A1 and multiple annular subregions (such as annular subregion A2, annular subregion A3 and annular subregion A4).Center subregion A1
Positioned at light receiving surface in the orthographic projection region on display screen 201, each annular subregion surrounds center subregion, the center
The shape of subregion A1 can be identical as the shape of light receiving surface.Center subregion A1 in the n sub-regions is apart from light-receiving
Face is nearest, and influence of the light that center subregion A1 is issued to the first brightness that luminance sensor detects is maximum, connects apart from light
Influence of the light that the remoter subregion in receipts face issues to the first brightness that luminance sensor detects is smaller.
It should be noted that Fig. 4 and orthographic projection region of the Fig. 5 only with light receiving surface on display screen 201 include middle center
It, optionally, should for region A1 and annular subregion A2, the shape of center subregion A1 and the shape of light receiving surface are rectangle
Orthographic projection region can also only include center subregion A1 and part-toroidal subregion A2, and the shape of the light receiving surface may be
Round or diamond shape etc., the embodiment of the present disclosure does not limit this.
In step 303, the corresponding luminance errors component of each subregion in n sub-regions is determined.
The embodiment of the present disclosure is for determining the corresponding error component of i-th of subregion in the n sub-regions to step
303 explain, 1≤i≤n, as shown in fig. 6, determining that the corresponding error component of i-th of subregion may include：
Step 3031 obtains the corresponding Benchmark brightness error of preset i-th of subregion.
It is exemplary, it can store the corresponding Benchmark brightness error of each subregion, Benchmark brightness error in display device
Experiment can be first passed through in advance to obtain.The corresponding Benchmark brightness error of i-th of subregion can be：Only have i-th on a display screen
When subregion issues the light of Benchmark brightness, the difference of the actual environment brightness of the brightness and display screen side of luminance sensor detection.It is bright
Determining device is spent it needs to be determined that when the corresponding luminance errors component of i-th of subregion, can be directly acquired in display device and be deposited
The corresponding Benchmark brightness error of i-th of subregion of storage, or that i-th of subregion can also be obtained by internet is corresponding
Benchmark brightness error.
Step 3032, the average brightness value for obtaining pixel in i-th of subregion.
Exemplary, brightness determining device can determine the image data that i-th of subregion is shown, and obtain this i-th
The number of pixels of subregion；Then brightness determining device can convert the image data to tone (English：Hue；Abbreviation H),
Saturation degree (English：Saturation；Referred to as：S) and brightness is (English：Value；Referred to as：V) color space (that is to say hsv color
Space), then according to the image data of conversion to hsv color space, obtain the brightness V value of each pixel；Brightness is true later
Multiple added luminances that device can will acquire are determined and divided by number of pixels, to obtain pixel in i-th of subregion
Average brightness value.
Step 3033 obtains preset first corresponding relationship.
Exemplary, the pixel brightness value that each subregion can be previously stored in display device is corresponding with error factor
Relationship, the first corresponding relationship can be the pixel brightness value of i-th of subregion and the corresponding relationship of error factor.It needs to illustrate
It is that error factor can be used to indicate that influence degree of the light of subregion sending to luminance errors component, the bigger table of error factor
Show that influence of the light of subregion sending to luminance errors component is bigger.Brightness determining device is it needs to be determined that i-th of sub-district
When the corresponding luminance errors component in domain, preset first corresponding relationship stored in display device can be first obtained.
For example, Fig. 7 shows the relation curve of a kind of pixel brightness value and error factor, as shown in fig. 7, being in abscissa
Pixel brightness value a, ordinate are in the coordinate system of error factor b, and curve p indicates the pixel brightness value and mistake of a sub-regions
The corresponding relationship of the poor factor.As shown in Figure 7, the brightness positive for the light that the error factor of a sub-regions and the subregion issue
It closes, the brightness for the light that a sub-regions issue is higher, and the error factor of the subregion is also bigger, and the light which issues is to bright
The influence for spending error component is bigger.
Step 3034 determines the corresponding error factor of average brightness value in the first corresponding relationship.
Brightness determining device can according in step 3032 determine i-th of subregion in pixel average brightness value,
The corresponding error factor of the average brightness value is searched in the first corresponding relationship.
Step 3035, by the product of Benchmark brightness error error factor corresponding with average brightness value, be determined as i-th of son
The corresponding original intensity error x in region.
It should be noted that since the original intensity error x is benchmark luminance errors error corresponding with average brightness value
The product of the factor, and the brightness of the error factor of subregion and the light of subregion sending is positively correlated, therefore the original intensity misses
The brightness for the light that poor x and i-th of subregion issue is positively correlated.Original intensity error x is：Only have i-th of sub-district in display screen
Domain shine, and issue light average brightness be step 3032 in determine average brightness value when, what luminance sensor detected
The difference of brightness and the actual environment brightness of display screen side.
It should be noted that the embodiment of the present disclosure is to pass through acquisition and Benchmark brightness error mistake corresponding with average brightness value
The poor factor, and the product of Benchmark brightness error and error factor is determined as original intensity error x；Optionally, it shows
The corresponding relationship of pixel brightness value Yu original intensity error can also be previously stored in device, and directly according to the corresponding relationship
Determine that the corresponding original intensity error of average brightness value, the embodiment of the present disclosure do not limit this.
Step 3036 determines the corresponding error coefficient y of i-th of subregion.
It should be noted that if the n sub-regions in display screen shine, then the light that other subregions issue will affect
The corresponding luminance errors component of i-th of subregion, other subregions be the n sub-regions in addition to i-th of subregion
Subregion.And the sum of brightness of light of other subregions sending is higher, the corresponding luminance errors component of i-th of subregion is got over
Greatly.Error coefficient can serve to indicate that other subregions to the influence degree of the corresponding luminance errors component of i-th of subregion, it is bright
Degree determining device can be determined by experiment the second corresponding relationship in advance, which can indicate that other subregions are sent out
The error coefficient of corresponding i-th of the subregion of the sum of brightness of light out, and error coefficient and the light of other subregions sending
The sum of brightness is positively correlated.
Brightness determining device when the average brightness value of pixel, can also determine other sub-districts in determining i-th of subregion
The sum of the brightness of light that domain issues, can directly search the corresponding error of the sum of the brightness in second corresponding relationship later
Coefficient, to obtain the corresponding error coefficient y of i-th of subregion.
Step 3037 determines the corresponding luminance errors component xy of i-th of subregion.
The corresponding luminance errors component of each subregion is：The product of its corresponding original intensity error and error coefficient,
Therefore brightness determining device can determine that the corresponding luminance errors component of i-th of subregion is xy.
It is exemplary, when determining the corresponding luminance errors component of i-th of subregion in step 303, it is assumed that brightness determines dress
Setting the Benchmark brightness error determined in step 3031 is 4 luxs, and the average brightness value obtained in step 3032 is less than base
The corresponding Benchmark brightness of quasi- luminance errors, the corresponding error factor of average brightness value determined in step 3034 is 0.9, then bright
Degree determining device can determine the corresponding lux original intensity error x=4 × 0.9=3.6 of i-th of subregion.Assume again that step
The error coefficient y=1.2 that brightness determining device determines in rapid 3036, then can determine the corresponding luminance errors of i-th of subregion
Component is the lux xy=3.6 × 1.2=4.32.It should be noted that the embodiment of the present disclosure is only with Benchmark brightness error for 4
Lux, error factor 0.9, for error coefficient y=1.2, optionally, which may be 3 luxs
Or 5 luxs, error factor may be 0.8 or 1.1, and error coefficient may be 1 or 1.3 etc., and the embodiment of the present disclosure is to this
Without limitation.
In step 304, by the sum of corresponding luminance errors component of n sub-regions, it is corresponding bright to be determined as luminance area
Spend error amount.
Brightness determining device is in determining n sub-regions after the luminance errors component of each subregion, so that it may determine the n
The luminance errors component of sub-regions is added, and the sum of error component is determined as the corresponding luminance errors value of luminance area.By
It is positively correlated in the brightness for the light that the corresponding subregion of each luminance errors component issues, then luminance errors value and brightness region
The brightness for the light that domain issues is positively correlated.
In step 305, the difference of the first brightness and luminance errors value is determined as the ambient brightness that display screen shows side.
Since the first brightness that luminance sensor detects is：The light and show that the received display screen of light receiving surface issues
The common brightness of the ambient light of display screen side, as long as therefore being determined that the light that display screen issues influences the brightness of the first brightness
It measures (that is to say luminance errors value), so that it may directly subtract the luminance errors value with the first brightness, obtain display screen and show side
Ambient brightness.
In the embodiment of the present disclosure, the first brightness that the available luminance sensor of brightness determining device detects, and determine
Luminance area in display screen, and the luminance area can be divided into n sub-regions；Then the brightness determining device can also obtain
Take the corresponding Benchmark brightness error of each subregion, error factor and error coefficient, and by the Benchmark brightness error, error because
The product of son and error coefficient, is determined as the corresponding luminance errors component of the subregion；Brightness determining device later
By the sum of corresponding n luminance errors component of n luminance area, it is determined as the corresponding luminance errors value of luminance area；It is last bright
Spending determining device can be by the difference of the first brightness and the luminance errors value, and the ambient brightness of side where being determined as display screen is realized
The ambient brightness of side where luminance sensor by the way that display backlight side is arranged in accurately determines display screen.
In conclusion the brightness that the embodiment of the present disclosure provides determines in method that luminance sensor can be set in display screen
Backlight side, and brightness determining device can determine the corresponding luminance errors value of the luminance area in display screen.If brightness senses
The brightness of the received light of device is the first brightness, then brightness determining device can be directly by the difference of first brightness and luminance errors value
