Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a kind of back light brightness regulating method and terminals, and it is very fast can to improve light intensity value variation
When screen display effect.
Referring to Fig. 1, Fig. 1 is a kind of flow diagram of back light brightness regulating method disclosed by the embodiments of the present invention.Fig. 1
Shown in back light brightness regulating method may comprise steps of:
S101, terminal obtain the light intensity value of predetermined number；
In the embodiment of the present invention, terminal may include mobile phone, tablet computer, portable device and other ends with screen
End equipment.Wherein, step S101 may include: the light intensity value that terminal passes through ambient light sensor continuous acquisition predetermined number；

Configuration is preset or by user's manual setting.
It should be noted that " continuous " is in the light intensity value that terminal passes through ambient light sensor continuous acquisition predetermined number
Refer to that the time interval of optical sensor acquisition light intensity value is continuous.
S102, terminal judge whether the light intensity value of the predetermined number belongs at least two backlight illumination grades, if this is pre-
If the light intensity value of number belongs at least two backlight illumination grades, S103 is thened follow the steps, it is no to then follow the steps S104.
Wherein, the corresponding light intensity value section of different backlight illumination grades is different.In the embodiment of the present invention, terminal can be pre-
First store the corresponding light intensity value section of multiple backlight illumination grades, the corresponding brightness value of each backlight illumination grade.For example,
First backlight illumination grade respective light intensities value section is [0,1]；The corresponding light intensity value area of second backlight illumination grade
Between be [2,5], the corresponding light intensity value section of third backlight illumination grade is [6,40], the 4th backlight illumination grade correspondence
Light intensity value section be [41,300], etc..
In the embodiment of the present invention, terminal judges whether the light intensity value of the predetermined number belongs at least two backlight illuminations etc.
Grade, it can be determined that whether the light intensity value of current environment is quickly changing, if belonging at least two backlight illumination grades, illustrates
The light intensity value of current environment is quickly changing, then can execute the backlight illumination that step S103 adjusts screen；If be not belonging to
Few two backlight illumination grades, then illustrate that the light intensity value of current environment is constant, and step S104 can be performed directly according to the light intensity
The backlight illumination of the corresponding backlight illumination grade setting screen of angle value.
The embodiment of the present invention, the light intensity value of the predetermined number belongs at least two backlight illumination grades in step s 102
When, the integration period of ambient light sensor can be reduced, so that ambient light sensor rapid data collection.For example, by 100ms's
Integration period is reduced to the integration period of 50ms, then acquiring time that 20 data need by ambient light sensor will be from
2s changes to 1s, can collect more data when acquiring light intensity value again in this way, and be unlikely to acquire more data
Overlong time cause backlight to adjust blunt feeling to user.Optionally, when step S102 judges the light of the predetermined number
Intensity value is not belonging at least two backlight illumination grades, that is, can be by ambient light sensing when belonging to the same backlight illumination grade
The integration period of device reverts to default value, executes existing back light brightness regulating method, the embodiment of the present invention is without limitation.
S103, terminal adjust the backlight illumination of screen according to the specific gravity of at least two backlight illuminations grade；
S104, terminal are bright according to the backlight of the backlight illumination grade setting screen in section where the light intensity value of predetermined number
Degree.
In the embodiment of the present invention, terminal judges that the light intensity value of the predetermined number belongs at least two backlight illumination grades
When, before terminal adjusts the backlight illumination of screen according to the specific gravity of at least two backlight illuminations grade, following step can be executed
It is rapid:
Terminal counts the number for the light intensity value that each backlight illumination grade includes in at least two backlight illuminations grade；
For each backlight illumination grade in at least two backlight illuminations grade, the light that backlight illumination grade includes is calculated
The number of intensity value and the ratio of predetermined number, using the ratio as the specific gravity of backlight illumination grade.
Wherein, terminal adjusts the backlight illumination of screen according to the specific gravity of at least two backlight illuminations grade, can be with are as follows: eventually
It is corresponding that the backlight illumination of screen is set the maximum backlight illumination grade of specific gravity in at least two backlight illuminations grade by end
Brightness value；Alternatively, setting specific gravity maximum and secondary two greatly in at least two backlight illuminations grade for the backlight illumination of screen
The average value of the corresponding brightness value of a backlight illumination grade；Or by the backlight illumination of screen to set at least two backlight bright
The specific gravity of grade and the sum of products of corresponding bright value are spent, the embodiment of the present invention is without limitation.
The light intensity value of the available predetermined number of the embodiment of the present invention belongs in the light intensity value for judging the predetermined number
When at least two backlight illumination grades, the backlight that can adjust screen according to the specific gravity of at least two backlight illuminations grade is bright
Degree, it is seen then that the embodiment of the present invention can change in faster environment to avoid in light intensity value, and what flashing occurred in terminal screen asks
Topic, and cause to adjust blunt problem using the stabilization mode adjusting backlight luminance of delay response.
Referring to Fig. 2, Fig. 2 is the flow diagram of another back light brightness regulating method disclosed by the embodiments of the present invention,
Step S201 to S202 and step in back light brightness regulating method shown in FIG. 1 in back light brightness regulating method shown in Fig. 2
S101 to S102 is identical, and I will not elaborate.Wherein, in step S202, terminal judges that the light intensity value of predetermined number belongs to
When at least two backlight illumination grades, step S203 to S205 can be executed.Correspondingly, in step S202, terminal is judged pre-
If the light intensity value of number is not belonging at least two backlight illumination grades, that is, when belonging to a backlight illumination grade, it can hold
Row step S206, step S206 are identical as step S104 in back light brightness regulating method shown in FIG. 1, and I will not elaborate.
S203, terminal determine maximum and secondary big two backlight illuminations etc. of specific gravity in at least two backlight illuminations grade
Grade；
The average brightness of the maximum brightness value corresponding with secondary two big backlight illumination grades of S204, terminal calculated specific gravity
Value；
The backlight illumination of screen is set the average brightness value by S205, terminal.
