For the brightness value after calibration.Specifically, when equation has multiple solution x1、x2、…、xNWhen, the brightness value after calibration can be expressed as：
For example, with reference to figure 5, for there are two solutions, current illumination reading is 15 luxs, at this point, the photograph after calibration
Angle value is the average value of two solutions.
According to other embodiment, in the case of getting current illumination reading in step s 12, by using above-mentioned
Formula 1 solves equation, if there is numerous desired illuminance value, then by maximum value in numerous desired illuminance value
xmaxWith minimum value xminAverage value as calibration after brightness value.In this case, the brightness value after calibration can indicate
For：
For example, with reference to figure 6, current illumination reading is 30 luxs, and 30 luxs correspond to the line chart of formula 1 in 30 Le
There are numerous solutions between 40 luxs by Ke Si, and therefore, in this case, the brightness value after calibration is 35 luxs.

On the other hand, desired illuminance function can be integrated, to obtain second integral result Ci, reference formula 3, the
Two integral result CiIt can be expressed as：
It is then possible to by first integral result CdWith second integral result CiError D of the ratio as piecewise function,
With regard to the error of optical sensor.Wherein, error D can be expressed as formula 4：
After determining error, the precision of the brightness value after being calibrated error as current illumination reading is joined
It examines.Specifically, the brightness value after the calculated calibrations of step S16 is Xm, it is D using 4 calculated error of formulam, then after calibrating
Final result can be expressed as Xm±Dm, for example, the brightness value after calculated calibration is 100, it is calculated using formula 4
Error is 5, then the final result after calibrating can be expressed as 100 ± 5.
It should be noted that the brightness value after calibration can be directly applied to other processing scenes.For example, automatic adjustment
