Rapid S1014 after smart television factory initialization, is first powered in use, user is prompted to carry out necessity taking a smart TV as an example
Correction, referring to Fig. 3, specifically:
After booting, step S1011 is executed, detection light sensitive component is formed by light sensation loop current Ix；
Step S1012 is executed, judges whether smart television has corrected that；
If it is not, thening follow the steps S1013, prompt user that must first be corrected maximal illumination scene, and record corresponding
Correcting current Ii, according to timing light sensation loop current value by most dark corresponding current value I0Electricity corresponding with maximal illumination scene
Flow valuve Im, establish the level of illumination mapping table of several current value sections and level of illumination one-to-one relationship；
Step S1014 is executed, several level of illumination and several white balance grades are obtained, updates level of illumination and white balance etc.
The one-to-one white balance grade mapping table of grade；
If judging, smart television is had corrected that, returns to detection light sensation loop current Ix。
Due to booting in use, updating level of illumination mapping table and white balance grade mapping table according to current illumination and depositing
Storage makes screen of intelligent device display effect close to current environment natural effect, improves viewing experience, avoid the need for by user according to
By the defect of remote controler manual switching adjustment white balance.

Carry out the correction of maximal illumination scene, specially following steps:
Step S1011', detection light sensitive component are formed by light sensation loop current Ix；
Step S1012', judges whether smart television has corrected that；If it is not, thening follow the steps S1013'；
Step S1013' prompts user that must first be corrected maximal illumination scene, and it is corresponding to record maximal illumination scene
Correcting current Imax；
Step S1014', by correcting current ImaX carries out trisection, obtains illumination trisection critical point current value I1、I2。
Optionally, I2Value size be I1Twice of value.
Optionally, level of illumination be divided into it is low it is bright, in it is bright, highlighted.
Optionally, I1For the first current value, I2For the second current value.
If judging, smart television is had corrected that, is returned to detection light sensitive component and is formed by light sensation loop current Ix。
Referring to Fig. 5, white balance grade mapping table, specially following steps are updated:
Step S1031, detection light sensitive component are formed by light sensation loop current Ix, obtain the corresponding light of current environment illumination
Feel loop current value Ia。
Step S1032, by the corresponding light sensation loop current value I of current environment illuminationaWith illumination trisection critical point electric current
Value I1、I2It compares, i.e., by current value IaWith the first current value I1With the second current value I2It compares.
Step S1033, if current value IaLess than the first current value I1When, it is judged as that current environment illumination is low bright；
If the corresponding light sensation loop current I of the real-time illumination of current environment is more than or equal to the first current value I1, and be less than or equal to
Second current value I2When, it is judged as that current environment illumination is bright in being；
If the corresponding light sensation loop current I of the real-time illumination of current environment is greater than the second current value I2When, judge current environment
It is highlighted for illumination.
Further, establish it is low it is bright, in bright, highlighted three level of illumination and white balance grade corresponding relationship, formed white
Equilibrium data group, and it is interior be stored in system, the corresponding relationship of level of illumination and white balance grade and colour temperature see the table below:
| Light levels | White balance grade | Colour temperature |
| It is low bright | Level-one | Warm colour temperature |
| In it is bright | Second level | Standard color temperature |
| It is highlighted | Three-level | Cool colour temperature |
Every group of white balance data only corresponds to one group of colour temperature, that is to say, that white balance data can reflect colour temperature situation.Bai Ping
Depending on the setting for the data group that weighs can be according to TV memory and screen display demand.
Further, the environment current illumination obtained according to step S1031 to step S1033, by calling white balance number
According to group, if judge environment current illumination for it is low bright when, by call white balance data group, match corresponding level-one white balance etc.
Grade, the corresponding switching of smart television screen display are adjusted to warm colour temperature；If judge environment current illumination be in it is bright when, by call it is white
Equilibrium data group, matches corresponding second level white balance grade, and the corresponding switching of smart television screen display is adjusted to standard color temperature；If
When judging environment current illumination to highlight, white balance data group is called, corresponding three-level white balance grade, smart television screen are matched
The corresponding switching of curtain display is adjusted to cool colour temperature.
In one embodiment, in smart television use process, light sensation loop current value is read every preset time and is worked as
Preceding luminance detection, optionally, preset time 5min, preset time can be arranged according to specific needs.
In the present embodiment, for the first time in use, correction maximal illumination scene acquisition pair after being initialized by smart television factory
The correcting current answered, and according to the correcting current by illumination by most secretly to most three level of illumination of bright division, presetting and depositing
The white balance data group of three level of illumination and three white balance grade corresponding relationships is stored up, every group of white balance data is correspondingly arranged one
Kind screen shows colour temperature.In use, obtaining the level of illumination of current environment by light sensitive component after correction, and according to the illumination etc.
Grade calls corresponding white balance grade in white balance data group, realizes white according to environment current illumination automatic switchover smart television
Balance realizes that automatically switching adjustment screen according to environment current illumination shows due to the corresponding colour temperature of one group of white balance data
Colour temperature, make Showing Effectiveness On Screen close to current environment natural effect, improve viewing experience, avoid the need for by user by distant
Control the defect of device manual switching adjustment white balance.
