S120, foundation survey brightness matrix and extreme brightness threshold value, determine that brightness value is located at extremely bright in smooth picture to be measured
Spend the region accounting in the extreme brightness region in section.
Wherein, extreme brightness threshold value is preset brightness value, be used to distinguish a brightness value be it is excessive it is (excessively bright),
It is normal or too small (excessively dark).The extreme brightness threshold value can be the fixed numbers of equipment factory setting；It is also possible to user or tune
The numerical value for the input interface input that examination engineer is provided by capture apparatus, to meet different application demands.This is extremely bright
Spending threshold value can be one, such as characterizes the too small very dark luminance threshold of brightness value or characterize the excessive incandescent brightness of brightness value
Threshold value；The extreme brightness threshold value may be two, i.e., extreme brightness threshold value includes very dark luminance threshold and incandescent luminance threshold.
Extreme brightness section is an extreme brightness numberical range, by extreme brightness threshold value and with extreme brightness threshold value
Corresponding brightness value is most worth generation.Such as extreme brightness threshold value is very dark luminance threshold, then the extreme brightness section is just by pole
Dark luminance threshold and brightness value minimum value generate.Brightness value most value refers to the value range for surveying brightness value in brightness matrix
Boundary value, may include brightness value minimum value and brightness value maximum value.Brightness value is most worth by the figure in capture apparatus

Weight table, carries out survey light to smooth picture to be measured.
When region accounting is less than default accounting threshold value, illustrate that the extreme brightness value surveyed in brightness matrix is to subsequent survey
Light has the noise brightness value of anomalous effects, then needs to carry out brightness adjustment to it.When it is implemented, will survey bright in brightness matrix
Each brightness value (extreme brightness value) that angle value belongs to extreme brightness section is adjusted according to predetermined luminance value adjustment rule to just
Normal brightness section, the brightness value that can obtain each matrix element are respectively positioned on the adjustment luminance matrix in normal brightness section.This is pre-
If brightness value adjustment rule, which can be, directly carries out brightness value setting, it is also possible to be scaled.
S140, foundation adjustment luminance matrix and the corresponding light metering weight table of target metering mode survey light to smooth picture to be measured.
Wherein, light metering weight table refers to the data for survey each weighted value composition used in light shading computation, can
To be matrix form, it is also possible to tabular form, as long as the corresponding weighted value distribution situation of target metering mode can be characterized i.e.
It can.For example, corresponding center average metering mode, then require in light metering weight table, act on and survey brightness matrix middle section

If S230, region accounting are less than default accounting threshold value, according to surveying the corresponding target brightness value of light picture, extremely bright
Threshold value and each extreme brightness value are spent, determines the corresponding adjustment brightness value of each extreme brightness value.
Wherein, target brightness value refers to that the brightness of smooth picture to be measured it is expected the brightness values being adjusted to, and is to survey light
The brightness values reached it is expected later with automatic exposure operation.
Illustratively, environment light when target brightness value is by survey light determines, and target brightness value is located at normal brightness section

Mark is so that each extreme brightness value is close to target brightness value.Meanwhile the boundary value in normal brightness section is pole
Luminance threshold is held, therefore extreme brightness value is adjusted to normal brightness section, is adjusted extreme brightness value to extreme luminance threshold
Between value and target brightness value.
To sum up, each extreme brightness value can be adjusted according to target brightness value and extreme brightness threshold value.For example,
It can be according to numeric distribution ratio of the extreme brightness value where it in numerical intervals (extreme brightness section), in extreme brightness threshold
Determine a brightness value as extreme brightness value adjustment brightness value adjusted between value and target brightness value；It for another example, can be with
According to the data distribution between the data distribution in extreme brightness section and extreme brightness threshold value and target brightness value, setting one
Number value comparison table directly searches corresponding adjustment brightness value of each extreme brightness value etc. according to the numerical comparatives table.
S240, each extreme brightness value surveyed in brightness matrix is replaced with into adjustment brightness corresponding with extreme brightness

Embodiment three
The present embodiment is on the basis of above-described embodiment two, to " according to surveying the corresponding target brightness value of light picture, extremely bright
Threshold value and each extreme brightness value are spent, determines the corresponding adjustment brightness value of each extreme brightness value " it is advanced optimized.Its
In the explanation of term identical or corresponding with the various embodiments described above details are not described herein.Referring to fig. 4, survey light provided in this embodiment
Method includes:
S310, the corresponding survey brightness matrix of smooth picture to be measured is obtained.
S320, foundation survey brightness matrix and extreme brightness threshold value, determine that brightness value is located at extremely bright in smooth picture to be measured
Spend the region accounting in the extreme brightness region in section.
Illustratively, when brightness value minimum value is 0 and brightness value maximum value is 255, very dark luminance threshold is 30,
Incandescent luminance threshold is 220.In this way, can determine very dark brightness section be [0,30), normal brightness section be [30,220], with
And incandescent brightness section be (220,255].
If S330, region accounting are less than default accounting threshold value, and if extreme brightness value be located at very dark brightness section, foundation
Target brightness value, very dark luminance threshold, brightness value minimum value and each extreme brightness value determine that each extreme brightness value is corresponding
Adjustment brightness value.
Specifically, referring to Fig. 3, if extreme brightness value 306 is fallen in very dark brightness section 310, it is directed to any one
Extreme brightness value determines the first brightness adjustment according to the extreme brightness value, brightness value minimum value and very dark luminance threshold first
Ratio；Secondly corresponding according to target brightness value, very dark luminance threshold and the first brightness adjustment ratio-dependent extreme brightness value
Adjust brightness value.When it is implemented, determining the corresponding adjustment brightness value of extreme brightness value of brightness to be adjusted according to following formula:
Wherein, result_lum indicates that adjustment brightness value, target_lum indicate target brightness value；Low_thr indicates pole
Dark luminance threshold, cur_lum indicate the extreme brightness value of brightness to be adjusted, and min_lum indicates brightness value minimum value.Why
Not directly using minuend as adjustment brightness value, be because minuend institute value may possibly still be present deviate target brightness value compared with
Big situation, the relatively large deviation caused by still can not weakening extreme brightness value well in this way in flash spotter calculation, therefore this hair
The calculated result of brightness value in bright embodiment with target brightness value and after being scaled is adjustment brightness value.
If S340, region accounting are less than default accounting threshold value, and if extreme brightness value be located at incandescent brightness section, foundation
Target brightness value, incandescent luminance threshold, brightness value maximum value and each extreme brightness value determine that each extreme brightness value is corresponding
Adjustment brightness value.
Specifically, referring to Fig. 3, if extreme brightness value 306 ' is fallen in incandescent brightness section 330, it is directed to any one

Wherein, hight_thr indicates that incandescent luminance threshold, max_lum indicate brightness value maximum value.
S350, each extreme brightness value surveyed in brightness matrix is replaced with into adjustment brightness corresponding with extreme brightness
Value obtains adjustment luminance matrix.
S360, foundation adjustment luminance matrix and the corresponding light metering weight table of target metering mode survey light to smooth picture to be measured.
For example, it is assumed that each weighted value is 1 in light metering weight table, and brightness value minimum value is 0, and brightness value is most
Big value is 255, and very dark luminance threshold is 30, and incandescent luminance threshold is 220, and presetting accounting threshold value is 30% and object brightness
Value is 60.
Referring to Fig. 5, there are 12*12 brightness values in the survey brightness matrix, and wherein brightness value 255 is greater than incandescent luminance threshold
Value 220, therefore there are incandescent luminance areas in the survey brightness matrix, and extreme brightness value 255 is entirely surveying brightness matrix
In region accounting are as follows: (12*3)/(12*12) * 100%=25% < 30%, and all extreme brightness values all fall within incandescent brightness
Region.
Initial photometric brightness so for being adjusted without brightness value are as follows: (255*12*3+50*12*9)/(12*12)
=101.25.
If need to first carry out extreme brightness value adjustment according to light measuring method provided by the embodiment of the present invention.So according to
Formula (2), adjustment brightness value result_lum=60+ (220-60) * (255- after each adjustment of extreme brightness value 255
255)/(255-220)=60.Later, the incandescent brightness value 255 in the substitution survey brightness matrix of brightness value 60 will be adjusted, obtained
Adjust luminance matrix.Finally, calculating target surveys light brightness: (60*12*3+50*12*9)/(12*12)=52.5.
Automatic exposure module (AE) is mainly to lead to according to light brightness is surveyed with the difference of target brightness value (target_lum)
Adjustment exposure value is crossed to come so that picture brightness reaches our target brightness value.By taking previous example as an example: the scene capture main body
Brightness is 50, and edge extreme brightness value is 255.Initial photometric brightness without brightness value adjustment is 101.25, therefore is
System can reduce picture brightness by reducing the light exposure of sensor sensor, so that final overall picture brightness can be reduced to
60, the brightness value 50 of shooting main part in this way can be down to lower brightness value, and the expectation with us is not inconsistent.By brightness value tune
It is 52.5 that whole target, which surveys light brightness, and the brightness value with shooting main body is closer to, and system will increase sensor exposure at this time
Amount, so that final overall picture brightness is increased to 60, can obtain to improve picture brightness and meet desired shooting picture.
The technical solution of the present embodiment, if being located at very dark brightness section by extreme brightness value, according to target brightness value,
Very dark luminance threshold, brightness value minimum value and each extreme brightness value determine the corresponding adjustment brightness of each extreme brightness value
Value；If extreme brightness value is located at incandescent brightness section, according to target brightness value, incandescent luminance threshold, brightness value maximum value
With each extreme brightness value, the corresponding adjustment brightness value of each extreme brightness value is determined.It is bright that more accurate adjustment can be obtained
Angle value further increases the accuracy for surveying light.
