Be illustrated in figure 1 the process flow diagram of a kind of luminance regulating method in the embodiment of the present invention, the method comprises:
S101, obtains adjustment parameter;
First, the method is applied in an electronic equipment in embodiments of the present invention, a gravity sensor is provided with in this electronic equipment, by this gravity sensor, this electronic equipment can be real-time the centre of gravity place detecting self, thus this electronic equipment just can get this self and the angle value between electronic equipment and surface level by this gravity sensor;
Here it should be noted that, in embodiments of the present invention, this angle value is the angle value between the back side of electronic equipment and surface level.Certainly, in the application of reality, this angle value can be the angle value between the front of electronic equipment and surface level, and that is how user self-definedly can carry out the angle value between detected electrons equipment and surface level.
Detect that, according to after this angle value, the adjustment parameter that this angle value is corresponding determined by this electronic equipment at electronic equipment.
Further, in embodiments of the present invention, this electronic equipment determines that adjustment parameter corresponding to this angle value is specially:
Bring the angle value got into preset formula, and obtain Output rusults;
Using Output rusults as adjustment parameter corresponding to angle value;
Specifically, in embodiments of the present invention, after electronic equipment detects angle value, this angle value is brought in preset formula and carries out computing by this electronic equipment, and this preset formula is as follows:
In this preset formula, K characterizes adjustment parameter, K
1, K
2for being kept at the setup parameter in described electronic equipment in advance, M characterizes the angle value detected.Here it should be noted that, K
1, K
2for by gathering two parameter values calculating of a large amount of data, because this parameter value has actual data to calculate, the parameter value that therefore different data obtain can slightly difference, but this difference can't have influence on technical scheme of the present invention to be performed.
According to above-mentioned preset formula, this electronic equipment is by after getting the angle value between self and surface level, and this electronic equipment just can be adjusted parameter by above-mentioned preset formula.
Here it should be noted that, this adjustment parameter is the parameter adjusting the illuminance that electronic equipment detects.
S102, obtains the illuminance in current environment, and will adjust the product of parameter and illuminance as the actual light illumination in current environment;
It should be noted that, substantial sequencing is not had in embodiments of the present invention between S101 and S102, S101 and S102 can carry out simultaneously, and namely this electronic equipment is when calculating adjustment parameter, and this electronic equipment just can detect the illuminance in current environment.
Specifically, in embodiments of the present invention, by arranging the first optical sensor on an electronic device, obtain the first illuminance, then using the first illuminance as the illuminance in current environment.This first optical sensor can be arranged on the front of electronic equipment or be arranged on the back side of electronic equipment, and its position arranged can set according to the demand in actual environment.Certainly, the front being arranged on electronic equipment selected by this first optical sensor in embodiments of the present invention, can make as much as possible like this not blocked by self or other objects during the first light sensors.
