In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, a backlight brightness adjustment method is provided, and this embodiment is exemplified by applying the method to a terminal device, and it is to be understood that the method may be applied to a server, and may also be applied to a system including the terminal device and the server, and is implemented by interaction between the terminal device and the server. In this embodiment, the method includes the steps of:
and step 110, when the light intensity information of the terminal equipment is acquired, determining the corresponding position information and distance information of the terminal equipment.
The light intensity information of the terminal device can be obtained by detecting the ambient light through the light receiving hole of the terminal device, specifically, the current ambient light of the terminal device is detected by using the existing ambient light sensor.
The terminal device can be an intelligent terminal device such as a smart phone, a smart watch, a tablet or a computer, and electronic devices capable of adjusting backlight brightness in the prior art are all suitable for the embodiment of the invention, and are not described in detail herein.
Specifically, when the terminal device detects the ambient light at the light receiving hole through the ambient light sensor provided by the terminal device to obtain the light intensity information corresponding to the current ambient light, the position information and the distance information of the current terminal device are determined at the same time.
The position information of the terminal equipment can be obtained through an acceleration sensor arranged in the terminal equipment, the position information can be used for determining the posture of the current terminal equipment, and the posture of the current terminal equipment determines whether the current terminal equipment is in a backlight condition or a light source approaching condition; the location information may also indicate the current terminal device angle to the horizontal. For example, the acceleration sensor may detect a vector of the terminal device in each of the x, y, and z axes, and further calculate an angle formed by the terminal device when the terminal device is facing upward and the horizontal plane.
The distance information of the terminal equipment can be obtained through a distance sensor arranged in the terminal equipment, and the distance information can be used for determining whether an obstacle exists in front of a light receiving hole where the current terminal equipment is located. As is known in the art, the light receiving hole is generally disposed on the front side of the terminal device, that is, on the same plane with the screen of the terminal device, so as to accurately obtain the current ambient light and adjust the screen brightness of the terminal device in time. In the scheme, in order to avoid the defect that the screen brightness is adjusted only according to the ambient light detected by the current light receiving hole without considering whether the current actual situation needs to adjust the screen brightness, the distance sensor is added, and if the distance sensor detects that the obstacle exists on the front face of the terminal device, the backlight brightness of the terminal device is not adjusted.
It can be understood that before the terminal device acquires the light intensity information, the method further includes: and calibrating the light sensation to eliminate the influence of the light receiving hole structure of the terminal equipment on the light sensation. Illustratively, the light receiving hole structure of the terminal equipment can be calibrated by light sensation under a D651000Lux light source.
And step 120, determining target light intensity information of the terminal equipment according to the light intensity information, the position information and the distance information.
And the target light intensity information is the light intensity corresponding to the backlight brightness determined according to the actual use condition of the current terminal equipment.
Specifically, whether the terminal device is backlight is determined based on the position information, reference light intensity information of the terminal device is determined based on the light intensity information, and whether an obstacle exists in front of a light receiving hole of the terminal device is determined based on the distance information; and determining target light intensity information according to the result of judging whether the backlight exists, the reference light intensity information and the result of judging whether the obstacle exists.
Wherein, the reference light intensity information of the terminal device is determined based on the light intensity information, including: acquiring a plurality of groups of light intensity information; and determining the reference light intensity information of the terminal equipment according to the multiple sets of light intensity information.
Specifically, a plurality of groups of light intensity information are collected through the terminal device, and an average value of light intensities corresponding to the plurality of groups of light intensity information is calculated to serve as reference light intensity information of the terminal device.
Further, if the terminal device is not backlighted and no obstacle exists in front of the light receiving hole of the terminal device, the target light intensity information is determined to be the reference light intensity information. And if the terminal equipment is in backlight and no barrier exists in front of the light receiving hole of the terminal equipment, determining target light intensity information according to the reference light intensity information and the distance information.
Further, determining the target light intensity information based on the reference light intensity information and the distance information includes: determining compensated light intensity information according to the light intensity information and the position information; if the light intensity corresponding to the compensated light intensity information is lower than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the reference light intensity information; or, if the light intensity corresponding to the compensated light intensity information is higher than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the compensated light intensity information.
It should be noted that, in the present application, if an obstacle exists in front of the light receiving hole of the terminal device, the target light intensity information is determined as the reference light intensity information, that is, the position and the current light intensity information of the terminal device are not considered any more, and further, it can be understood that, when the screen of the terminal device is placed downward on the desktop, that is, the current situation is generally that the user is not using the terminal device, the current situation of the terminal device can be fed back to the controller of the terminal device to control the terminal device to rapidly enter the sleep mode, so that the power consumption of the terminal device is reduced.
And step 130, adjusting the backlight brightness of the terminal equipment according to the target light intensity information.
The backlight brightness of the terminal device can be determined according to the light intensity information of the currently detected ambient light, and it can be understood that after the terminal device starts the automatic backlight brightness adjusting function, the terminal device can automatically adjust the screen backlight brightness according to the detected current ambient light.
Specifically, when the target light intensity information is determined to be the reference light intensity information, the backlight brightness of the terminal device is adjusted according to the reference light intensity information; and when the target light intensity information is determined to be the compensation light intensity information, adjusting the backlight brightness of the terminal equipment according to the compensation light intensity information.
In the backlight brightness adjusting method, when the light intensity information of the terminal equipment is obtained, the position information and the distance information corresponding to the terminal equipment are determined; determining target light intensity information of the terminal equipment according to the light intensity information, the position information and the distance information; and adjusting the backlight brightness of the terminal equipment according to the target light intensity information. The problem of prior art's intelligent terminal luminance setting in a poor light can't be according to the accurate adaptation of actual conditions is solved to even realize being in a poor light or under the condition of sheltering from at terminal equipment, also can accurate adaptation current environment.

And step 121, determining whether the terminal equipment is backlight based on the position information, determining reference light intensity information of the terminal equipment based on the light intensity information, and determining whether an obstacle exists in front of a light receiving hole of the terminal equipment based on the distance information.
Specifically, the virtual light sensation sensor acquires position information through the acceleration sensor, and the posture of the terminal device is judged according to the position information so as to further determine whether the terminal device is in backlight. For example, the acceleration sensor may detect directions of x, y, and z axes of the terminal device, so as to calculate an angle of the terminal device facing downward, and the degree of backlight of the terminal device may be compared with the angle, so as to determine a degree of compensation for the ambient light sensor, where the degree of compensation for the ambient light sensor is a dynamic compensation light intensity corresponding to the terminal device in a process from an upright state to a screen-down state.
The virtual light sensation sensor acquires the distance information through the distance sensor, whether an obstacle exists on the front face of the terminal equipment is judged according to the distance information, and when the obstacle exists on the front face of the terminal equipment, the target light intensity information of the terminal equipment is determined to be reference light intensity information.
Further, determining reference light intensity information of the terminal device based on the light intensity information includes: acquiring a plurality of groups of light intensity information; and determining the reference light intensity information of the terminal equipment according to the multiple sets of light intensity information.
Specifically, when the light intensity information of the terminal device is acquired, the virtual light sensor collects multiple groups of light intensity information, and the reference light intensity information is obtained by averaging the light intensities corresponding to the multiple groups of light intensity information.
It can be understood that when the virtual light sensation sensor determines that the front side of the screen of the terminal device has an obstacle through the distance sensor, the reference light intensity information is directly used as the current target light intensity information, that is, the backlight brightness of the terminal device is adjusted according to the reference light intensity information.
And step 122, determining target light intensity information according to the result of judging whether the backlight exists, the reference light intensity information and the result of judging whether the obstacle exists.
Specifically, if the terminal device is not backlighted and no barrier exists in front of a light receiving hole of the terminal device, determining the target light intensity information as reference light intensity information; if the terminal equipment is in backlight and no barrier exists in front of a light receiving hole of the terminal equipment, determining compensation light intensity information according to the light intensity information and the position information; if the light intensity corresponding to the compensated light intensity information is lower than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the reference light intensity information; or, if the light intensity corresponding to the compensated light intensity information is higher than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the compensated light intensity information.
And step 130, adjusting the backlight brightness of the terminal equipment according to the target light intensity information.
Specifically, when the target light intensity information is determined to be the reference light intensity information, the backlight brightness of the terminal device is adjusted according to the reference light intensity information; and when the target light intensity information is determined to be the compensation light intensity information, adjusting the backlight brightness of the terminal equipment according to the compensation light intensity information.
According to the backlight brightness adjusting method, after the terminal device is used for starting the virtual light sensation sensor, the distance sensor, the acceleration sensor and the ambient light sensor are monitored, the attitude information of the terminal device is determined through the acceleration sensor, whether an obstacle blocks the terminal device is judged through the distance sensor, the light intensity detected by the ambient light sensor is determined and compensated according to the light intensity information of the current terminal device, and therefore the backlight brightness of the terminal device is automatically and flexibly controlled according to different environments of the terminal device.
In an embodiment, as shown in fig. 3, a method for adjusting backlight brightness is provided, and accordingly, the steps of this embodiment specifically include:
and step 110, when the light intensity information of the terminal equipment is acquired, determining the corresponding position information and distance information of the terminal equipment.
And step 121, determining whether the terminal equipment is backlight based on the position information, determining reference light intensity information of the terminal equipment based on the light intensity information, and determining whether an obstacle exists in front of a light receiving hole of the terminal equipment based on the distance information.
And 1221, if the terminal equipment is not backlit and no obstacle exists in front of the light receiving hole of the terminal equipment, determining the target light intensity information as reference light intensity information.
It can be understood that if the terminal device is not backlit, it may indicate that the front side of the terminal device is close to the light source at this time, and it is determined that no obstacle exists in front of the light receiving hole of the terminal device, that is, the reference light intensity information of the terminal device determined according to the light intensity information may be used as the target light intensity information.
It should be noted that, if an obstacle exists in front of the light receiving hole of the terminal device, the target light intensity information is determined as the reference light intensity information.
And step 130, adjusting the backlight brightness of the terminal equipment according to the target light intensity information.
Specifically, when the target light intensity information is determined to be the reference light intensity information, the backlight brightness of the terminal device is adjusted according to the reference light intensity information.
In the backlight brightness adjusting method, when the terminal equipment is determined to be used close to the light source at the moment, the reference light intensity information is used as the backlight brightness adjusting basis of the current terminal equipment, so that the normal display of the screen brightness of the terminal equipment is ensured.
In an embodiment, as shown in fig. 4, a method for adjusting backlight brightness is provided, and accordingly, the steps of this embodiment specifically include:
and step 110, when the light intensity information of the terminal equipment is acquired, determining the corresponding position information and distance information of the terminal equipment.

And 1222, if the terminal device is in backlight and no obstacle exists in front of the light receiving hole of the terminal device, determining the target light intensity information according to the reference light intensity information and the distance information.
On the basis of the above embodiment, determining the target light intensity information according to the reference light intensity information and the distance information includes: determining compensated light intensity information according to the light intensity information and the position information; if the light intensity corresponding to the compensated light intensity information is lower than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the reference light intensity information; or, if the light intensity corresponding to the compensated light intensity information is higher than the light intensity corresponding to the reference light intensity information, determining the target light intensity information as the compensated light intensity information.
Specifically, under a calibration environment of a D651000Lux (Lux, lighting unit) light source, when a screen of the terminal device is upward and an angle formed by the screen and a horizontal plane is smaller than a preset angle threshold, optionally, the preset angle threshold is 30 degrees, a plurality of sets of light intensity information are sampled, and a plurality of angles of the terminal device are determined according to a plurality of sets of position information of the terminal device; calculating the standard light intensity of 1000Lux and the deviation light intensity of the light intensity corresponding to the multiple groups of light intensity information; analyzing the linear relation between a plurality of angles and the deviation light intensity, and determining a reasonable deviation light intensity and angle linear relation variance, wherein if the deviation light intensity is the angle A + B, A and B are obtained by the statistics of the plurality of groups of data; the light intensity corresponding to the compensation light intensity information is equal to the light intensity corresponding to the light intensity information plus the deviation light intensity. The D65 light source is the most commonly used artificial sunlight in standard light sources.
