Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of method of backlight regulation is the embodiment of the invention provides, methods described is applied to the electronics with display screen and sets
In standby, and the background luminance of the display screen can adjust, and the electronic equipment includes：Smart mobile phone, panel computer etc., such as Fig. 1
Shown, methods described includes：
Step 101, when each user sets the backlight illumination of electronic equipment, obtain the backlight illumination of each user setting
And the illumination of each place environment of electronic equipment, and the backlight illumination that each user is set and each place ring of electronic equipment
The corresponding relation of the illumination in border is preserved.
Electronic equipment can determine backlight illumination according to the illumination of place environment in the correspondence set of systemic presupposition.
If the user thinks that the backlight illumination that currently displaying screen shows cannot meet normally using, current backlight illumination can be adjusted
Section.During regulation, as shown in Fig. 2 can be adjusted by sliding backlight adjusting slider：When sliding block slides into the slide rail leftmost side,
Screen intensity is minimum value；When sliding block slides into the slide rail rightmost side, screen intensity is maximum.
Specifically, being preserved to the backlight illumination that each user sets by following two ways：
1st, by default correspondence set with the backlight illumination corresponding to the illumination identical illumination of each place environment
The backlight illumination of each user's setting is replaced with, the set of correspondences of the illumination and the backlight illumination of user's setting is obtained
Close.The correspondence set of the backlight illumination that the illumination that will be obtained sets with user is preserved.
As shown in table 1, the illumination containing systemic presupposition and the corresponding relation of backlight illumination in default correspondence set, lack
Save correspondence set and have recorded corresponding backlight illumination under whole illumination.

| 2999 | 200 |
| … | … |
| 4 | 2 |
| 3 | 1 |
| 2 | 1 |
| 1 | 1 |
When the backlight illumination set to each user is preserved, searched in table 1 and ring where each electronic equipment
Backlight illumination corresponding to the illumination identical illumination in border replaces with the backlight illumination of each user's setting.For example, certain
The illumination of environment is 2 luxs where electronic equipment, and the backlight illumination that user sets is 3, then as shown in table 2, by default correspondence
Illumination is 2 in set of relationship, and backlight illumination is that 1 record replaces with illumination for 2, and backlight illumination is 3.

| 2 | 3 |
| 1 | 1 |
2nd, the backlight illumination set according to each user is right with the illumination of electronic equipment environment where each
Should be related to and be added in self-defined correspondence set, obtain the set of correspondences of the illumination and the backlight illumination of user's setting
Close.The correspondence set of the backlight illumination that the illumination that will be obtained sets with user is preserved.
As shown in table 3, its record has the backlight illumination and the electronics that user sets every time to self-defined correspondence set
The corresponding relation of the illumination of environment where equipment is each.

| 2500 | 300 |
| 1000 | 200 |
| … | … |
| 4 | 2 |
| 500 | 30 |
During each user's setting backlight illumination, the numerical value that user is set is preserved.For example：What certain user was set
Backlight illumination is 30, and now the illumination of environment where electronic equipment is 400, then as shown in table 4, in self-defined correspondence set
In, addition illumination is 400, and backlight illumination is 30 record.
Table 4
| Illumination（Lux） | Backlight illumination（Lux） |
| 2500 | 300 |
| 1000 | 200 |
| … | … |
| 4 | 2 |
| 500 | 30 |
| 400 | 30 |
When the illumination of environment changes, search what is be consistent with the illumination after change in self-defined correspondence set
Record, obtains backlight illumination.If not finding the record being consistent with the illumination after change in self-defined correspondence set,
Prompting user sets backlight illumination, or determines backlight illumination from default correspondence set.
When step 102, the illumination of environment where the electronic equipment change, the illumination after change is obtained, preserved
Illumination and user setting backlight illumination correspondence set in, search with change after the corresponding backlight illumination of illumination.
Step 103, the backlight illumination of the display screen of electronic equipment is adjusted to the backlight illumination that obtains of lookup.
Further, as shown in Fig. 2 being set with the electronics in step 101, by the backlight illumination of each user's setting
After the corresponding relation of the illumination of the standby environment of place every time is preserved, methods described also includes：
Step 201, in the correspondence set of the backlight illumination that the illumination for having preserved and user set, search first and treat
Modification corresponding relation, wherein, the illumination and the back of the body of the illumination less than electronic equipment environment where each of the first corresponding relation to be modified
Backlight illumination of the brightness more than each user setting.
Step 202, the backlight illumination that the illumination in corresponding relation is set to no more than each user's setting.
Further, as shown in figure 3, in step 101, the backlight illumination and the electricity by each user's setting
After the corresponding relation of the illumination of environment is preserved where sub- equipment is each, methods described also includes：
Step 301, in the correspondence set of the backlight illumination that the illumination for having preserved and user set, search second and treat
Modification corresponding relation, wherein, the illumination and the back of the body of the illumination more than electronic equipment environment where each of the second corresponding relation to be modified
Backlight illumination of the brightness less than each user setting.
Step 302, the backlight illumination for being set to be set not less than each user by the illumination in corresponding relation.
After the corresponding relation of each illumination for preserving user's setting and backlight illumination, due to the backlight illumination that user is set
Differ larger with the backlight illumination of system default so that the backlight illumination corresponding to the illumination adjacent with ambient light illumination sets with user
The backlight illumination difference put is larger, backlight illumination jump occurs.
For example:As shown in table 5, it is 2 that what this was preserved is recorded as illumination, and backlight illumination is 8.Now, illumination is 2 record
In, backlight illumination is 8.But be 87 to record corresponding backlight illumination respectively less than this guarantor to illumination from the record that illumination is 3
The backlight illumination deposited.Now need to having preserved from the record that illumination is 3, be 87 to record corresponding backlight illumination to illumination
It is adjusted, backlight illumination is adjusted to 8, adapts to the backlight illumination 8 of this preservation.

| 1 | 1 |
As shown in table 6, the corresponding backlight illumination that records that record to the illumination that illumination is 3 is 87 is all adjusted to 8, is made
Obtain illumination and record corresponding backlight illumination not less than 8 more than 2.
