Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiments provide a kind of method that backlight regulates, described method is applied to be had in the electronic equipment of display screen, and the background luminance of described display screen is adjustable, and described electronic equipment comprises: smart mobile phone, panel computer etc., as shown in Figure 1, described method comprises:
Step 101, when each user sets the backlight illumination of electronic equipment, obtain the backlight illumination of each user setting and the illumination of electronic equipment each place environment, and the corresponding relation of the illumination of the backlight illumination each user set and electronic equipment each place environment is preserved.
Electronic equipment according to the illumination of place environment in the correspondence set of systemic presupposition, can determine backlight illumination.If user thinks that the backlight illumination that current display screen shows cannot meet normal use, can current backlight illumination be regulated.During adjustment, as shown in Figure 2, regulate by slip backlight adjusting slider: when skid is to the slide rail leftmost side, screen intensity is minimum value; When skid is to the slide rail rightmost side, screen intensity is maximal value.
Concrete, by following two kinds of modes, the backlight illumination that each user sets is preserved:
1, the backlight illumination corresponding to illumination identical with the illumination of each place environment in default correspondence set is replaced with the backlight illumination that described each user sets, obtain the correspondence set of the backlight illumination that described illumination and user set.The correspondence set of the backlight illumination described illumination obtained and user set is preserved.
As shown in table 1, containing the illumination of systemic presupposition and the corresponding relation of backlight illumination in default correspondence set, the backlight illumination that default correspondence set is corresponding under have recorded whole illumination.

| 2999 | 200 |
| … | … |
| 4 | 2 |
| 3 | 1 |
| 2 | 1 |
| 1 | 1 |
When the backlight illumination set each user is preserved, the backlight illumination searched in Table 1 corresponding to the illumination identical with the illumination of each electronic equipment place environment replaces with the backlight illumination that described each user sets.Such as, the illumination of certain electronic equipment place environment is 2 luxs, and the backlight illumination of user's setting is 3, then as shown in table 2, is 2 by illumination in default correspondence set, backlight illumination be 1 record to replace with illumination be 2, backlight illumination is 3.

| 2 | 3 |
| 1 | 1 |
2, add in self-defined correspondence set according to the corresponding relation of the described backlight illumination of each user setting and the illumination of described electronic equipment each place environment, obtain the correspondence set of the backlight illumination that described illumination and user set.The correspondence set of the backlight illumination described illumination obtained and user set is preserved.
Self-defined correspondence set is as shown in table 3, and it records the corresponding relation of the illumination of backlight illumination that user sets at every turn and described electronic equipment each place environment.

| 2500 | 300 |
| 1000 | 200 |
| … | … |
| 4 | 2 |
| 500 | 30 |
When each user sets backlight illumination, all the numerical value that user is arranged is preserved.Such as: the backlight illumination that certain user is arranged is 30, and now the illumination of electronic equipment place environment is 400, then as shown in table 4, in self-defined correspondence set, adding illumination is 400, and backlight illumination is the record of 30.
Table 4
| Illumination (lux) | Backlight illumination (lux) |
| 2500 | 300 |
| 1000 | 200 |
| … | … |
| 4 | 2 |
| 500 | 30 |
| 400 | 30 |
When the illumination of environment changes, search in self-defined correspondence set with change after the record that conforms to of illumination, obtain backlight illumination.If do not find in self-defined correspondence set with change after the record that conforms to of illumination, then point out user that backlight illumination is set, or determine backlight illumination from default correspondence set.
Step 102, when the illumination of electronic equipment place environment changes, obtain the illumination after change, in the correspondence set of the backlight illumination set in the illumination of having preserved and user, search with change after backlight illumination corresponding to illumination.
Step 103, the backlight illumination of the display screen of electronic equipment is adjusted to the backlight illumination searched and obtain.
Further, as shown in Figure 2, after the corresponding relation of the illumination of step 101, the backlight illumination described each user set and described electronic equipment each place environment is preserved, described method also comprises:
In step 201, the correspondence set of backlight illumination that sets in the illumination of having preserved and user, search the first corresponding relation to be modified, wherein, the illumination of the first corresponding relation to be modified is less than the illumination of electronic equipment each place environment and backlight illumination is greater than the backlight illumination of each user setting.
Step 202, the illumination in corresponding relation is set to the backlight illumination being not more than each user setting.
Further, as shown in Figure 3, after step 101, the described corresponding relation by the described backlight illumination of each user setting and the illumination of described electronic equipment each place environment are preserved, described method also comprises:
In step 301, the correspondence set of backlight illumination that sets in the illumination of having preserved and user, search the second corresponding relation to be modified, wherein, the illumination of the second corresponding relation to be modified is greater than the illumination of electronic equipment each place environment and backlight illumination is less than the backlight illumination of each user setting.
Step 302, the illumination in corresponding relation is set to the backlight illumination being not less than each user setting.
After the corresponding relation of the illumination that each preservation user is arranged and backlight illumination, the backlight illumination arranged due to user differs larger with the backlight illumination of system default, the backlight illumination that backlight illumination corresponding to the illumination adjacent with ambient light illumination and user are arranged differs comparatively large, occurs backlight illumination jump.
Such as: as shown in table 5, this illumination that is recorded as of preserving is 2, and backlight illumination is 8.Now, illumination is in the record of 2, and backlight illumination is 8.But be the record of 3 from illumination, be that the backlight illumination of the record correspondence of 87 is all less than this backlight illumination preserved to illumination.Now needing what preserved is the record of 3 from illumination, is that the backlight illumination of the record correspondence of 87 adjusts, backlight illumination is all adjusted to 8 to illumination, to adapt to the backlight illumination 8 that this is preserved.
