Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the appended claims.

As shown in Figure 1, the housing of the terminal device is provided with an opening. The light sensor is placed in the housing and at the opening. The ambient light is incident on the light sensor through the opening. The light sensor detects the ambient brightness based on the incident ambient light. information. The detection field of view range of this light sensor is A.

As shown in FIG. 2 , the light source 201 is disposed in the direction of the back 204 of the display surface of the terminal device, the user 205 is located in the direction of the display surface 202 of the terminal device, and the light sensor 203 is disposed on the plane where the display surface 202 of the terminal device is located.

In the actual process of setting the screen brightness, the brightness of the screen needs to be adjusted to match the brightness perceived by the user. Since the light sensor is facing away from the light source and the user is facing the light source, the light sensor can actually only collect the light reflected by the user within the field of view A, and what it collects is not what the user actually perceives. of light, thus causing the detection value of the light sensor to be smaller than the brightness value perceived by the actual user. It can be seen that if the screen brightness is directly adjusted through the detection value of the light sensor, the adjusted screen brightness may not meet the actual screen brightness required by the user.

In the existing method, two light sensors are provided on the terminal equipment. One light sensor is placed on the side where the display surface of the terminal equipment is located, and the other light sensor is placed on the back side of the display surface of the terminal equipment. This is achieved by Adding additional light sensors to solve the problem of limited field of view of light sensors has the problem of occupying the space of terminal equipment and increasing design difficulty and cost.

Based on this, an embodiment of the present disclosure proposes a method for adjusting screen brightness. Figure 3 is a flowchart 1 of a method for adjusting screen brightness according to an embodiment of the present disclosure. As shown in Figure 3, the method applied to a terminal device includes Following steps:

S11. Obtain the brightness model of the space where the terminal device is currently located;

S12. Determine the relative position between the terminal device and the light source in the current space;

S13. Obtain compensation information based on the relative position and brightness model between the terminal device and the light source in the current space;

S14. Use the compensation information to compensate the first environment brightness information detected by the terminal device, and obtain the compensated second environment brightness information;

S15. Based on the second environment brightness information, adjust the screen brightness of the terminal device.

The above-mentioned terminal device is a terminal device provided with a screen. The terminal device may be a wearable electronic device and a mobile terminal. The mobile terminal includes a mobile phone, a notebook and a tablet computer. The wearable electronic device includes a smart watch. The embodiments of this disclosure are not limit.

The brightness model is stored on the terminal device. The brightness model at least includes: environmental brightness information corresponding to different relative positions between the terminal device and the light source in the current space. Determining the brightness model of the space where the terminal device is currently located includes: reading the brightness model information that matches the current space from the memory to obtain the brightness model; or, when there is no brightness model that matches the current space in the memory, According to the environmental brightness information corresponding to different relative positions between the terminal device and the light source in the current space, a brightness model of the space where the terminal device is currently located is generated.

In the embodiment of the present disclosure, the position of the terminal device in the current space changes in real time. For example, when the user is standing, the position between the terminal device and the light source is one position; when the user is lying down, the position between the terminal device and the light source is The position is another position. In addition, the environmental brightness information of the terminal device is different in different positions. For example, the ambient brightness value detected by the terminal device at a position close to the light source is higher than the ambient brightness value detected at a position far away from the light source. Therefore, in the process of adjusting the screen brightness, it is necessary to determine the relative position between the terminal device and the light source, and the compensation information can be accurately determined based on the relative position between the terminal device and the light source.

It should be noted that the relative position between the terminal device and the light source includes: the angle between the terminal device and the light source on the horizontal plane, and/or the angle between the terminal device and the light source on the vertical plane.

As shown in FIG. 4 , the angle between the terminal device 101 and the light source 102 on the horizontal plane is α. As shown in FIG. 5 , the angle between the terminal device 101 and the light source 102 on the vertical plane is β.

It should be noted that when the ambient light in the space where the terminal device is currently located is relatively complex, that is, when there are multiple light sources or different types of light sources in the space, the detection value of the light sensor on the terminal device cannot be accurately reflected in the detection field of view range. external environment brightness information. Therefore, it is necessary to compensate the detected first environment information of the terminal device through the compensation information to obtain the compensated second environment brightness information, and then use the second environment brightness information to adjust the screen brightness information of the terminal device.

In this way, on the one hand, the embodiments of the present disclosure take into account that changes in the position, such as posture, of the terminal device will affect the detected environment brightness information. Therefore, the implementation of the present disclosure obtains compensation information through the relative position between the terminal device and the light source, and can adapt to the situation of the terminal device. Due to the changing position of the light source, accurate compensation information can be obtained to improve the adjustment accuracy of screen brightness; on the other hand, embodiments of the present disclosure adjust the brightness of the terminal device based on the compensated second environment brightness information, It is no longer necessary to directly adjust the screen brightness of the terminal device through the detected first environment brightness information, making the screen brightness adjustment more accurate, more in line with the user's perception, and improving the user experience.

At the same time, compared with the existing method of setting up multiple light sensors to detect ambient light information in the space, for example, one light sensor is provided on the surface where the display surface is located, and one light sensor is provided on the back of the display surface. The method proposed by the embodiment of the present disclosure is Adjusting the screen brightness through software does not require additional hardware in the terminal device. It can simplify the structural design of the terminal device, reduce the number of light sensors in the terminal device, adapt to the miniaturization development of the terminal device, and also save the cost of the terminal device. manufacturing costs.

In one embodiment, obtaining the brightness model of the space where the terminal device is currently located includes:

Detect the posture information of the terminal device;

Detect the ambient brightness information of the terminal device in different postures;

According to the posture information and the environment brightness information, a brightness model of the space where the terminal device is currently located is generated.

It should be noted that the embodiments of the present disclosure can determine whether the brightness model has been established in the current space that the terminal device enters based on the positioning information of the terminal device; when the brightness model has not been established in the current space that the terminal device enters, output the brightness model established prompt information; and detect the posture information of the terminal based on the prompt information.

In the embodiment of the present disclosure, the terminal device can determine the positioning information of the terminal device through WIFI signals, mobile signals or Bluetooth positioning in the space where it is located. For example, the terminal device is covered with WIFI signals. When the terminal device is close to the WIFI signal transmitter, the WIFI signal is strong. When the terminal device is far away from the WIFI signal transmitter, the WIFI signal is weak. Moreover, the WIFI signal transmitter is in the space. The location is fixed, so the terminal device can be located based on the strength of the WIFI signal.

The light sources in different spaces may be different, and the environmental brightness information detected by the terminal device under different light sources is different. Therefore, the brightness models in different spaces are different. Furthermore, when the terminal device enters the current space, it needs to be determined whether a brightness model has been established in the current space of the terminal device. If the brightness model has been established in the current space, during the process of adjusting the screen brightness, the brightness model can be directly queried in the memory; if the terminal device enters the current space and no brightness model has been established, it is required during the process of adjusting the screen brightness. Establish a brightness model. At this time, the terminal device can output prompt information for establishing the brightness model and generate a brightness model.

It should be noted that the failure to establish a brightness model when the terminal device enters the current space includes: the terminal device enters the current space for the first time and then does not establish a brightness model in the current space. Therefore, in the process of determining that the terminal device has entered the current space and no brightness model has been established, it may be first determined whether the terminal device has entered the current space for the first time.

When the terminal device does not enter the current space for the first time, and the brightness model of the current space is stored in the memory, the brightness model can be directly queried and obtained in the memory. When the terminal device enters the current space for the first time, it indicates that the brightness model is not established in the space where the terminal device is currently located. Therefore, it is necessary to further output prompt information for establishing the brightness model and generate a brightness model.

The prompt information established by the above output brightness model includes: displaying a prompt box on the screen, and displaying the prompt information in the prompt box. This prompt information is used to prompt the user to rotate the terminal device to calibrate the terminal device.

The above prompt information includes: prompt information for changing the posture of the terminal device or prompt information for rotating the terminal device, which are not limited in the embodiments of the present disclosure. Among them, during the process of rotating the terminal device, the terminal device can obtain environmental brightness information in different postures.

The posture of the terminal device may include an angle between the terminal device and a vertical direction of the first plane, and/or an angle between the terminal device and a vertical direction of the second plane, where the first plane is perpendicular to the second plane.

For example, the first plane may be a plane perpendicular to the ground, and the second plane may be a plane parallel to the ground.

The above-mentioned attitude detection device for detecting attitude information may include a rotation vector sensor that is one or a combination of sensors such as an acceleration sensor, a magnetic field sensor, or a gyroscope sensor of the terminal device. The brightness detection device that detects environmental brightness information may include a light sensor, which is not limited by the embodiments of the present disclosure.

It should be noted that the rotation vector of the rotation vector sensor can represent the rotation angle of the terminal device using a combination of the rotation angle and the rotation axis. The rotation axis includes: X axis, Y axis and Z axis. Among them, the X-axis is defined by the vector product Y*Z. The X-axis is tangent to the ground at the current position of the terminal device and points to the east; the Y-axis is tangent to the ground at the current position of the terminal device and points to the geomagnetic field. North Pole; the Z-axis direction points to the sky and is perpendicular to the ground.

For example, as shown in FIG. 6 , the rotation axis of the rotation vector sensor and the direction of the rotation vector can be defined by an orthogonal basis to constitute the reference coordinate system xyz.

Assume that the terminal equipment rotates counterclockwise around a certain rotation axis through point O by a rotation angle θ, then the quaternion q corresponding to the triangular form of the terminal equipment in the reference coordinate system is formula (1):

q＝cos(θ/2)+sin(θ/2)cosα*i+sin(θ/2)cosβ*j+sin(θ/2)cosγ*k (1)

Among them, α, β and γ are the angles between the rotation axis and each axis of the reference coordinate system, and i, j and k are the three imaginary parts corresponding to the quaternion.

In the embodiment of the present disclosure, after generating the brightness model, the terminal device stores the brightness model. A model storage database can be specially set up on the terminal device, so that the corresponding brightness model can be obtained by directly querying the model storage database. The storage database may be set in the readable memory of the terminal device or in the readable and writable memory of the terminal device, which is not limited by the embodiment of the present disclosure.

It can be understood that, on the one hand, the embodiments of the present disclosure can directly use the sensor on the terminal device to detect the posture and environmental brightness information of the terminal device to determine the brightness model, without the need to set up an additional detection device, which can not only improve the space utilization of the terminal device It can also reduce the design cost of additional detection devices. On the other hand, embodiments of the present disclosure take into account that the current posture of the terminal device and the position between the terminal device and the light source in different postures will affect the detected environment brightness information. Therefore, the brightness model generated based on the terminal's posture information and the environment brightness information can Provide accurate data for subsequent determination of compensation information based on the brightness model. At the same time, when the terminal device enters the same space, it can directly query the model storage database to obtain the brightness model information in the space without repeatedly establishing the brightness model, which can reduce the execution steps required to adjust the screen brightness and improve Adjust efficiency.

In one embodiment, a brightness model of the space where the terminal device is currently located is generated based on the posture information and the environment brightness information, including:

According to the detection time of the attitude information and the environment brightness information, determine the environment brightness information when the terminal device is at different angles to the vertical direction of the first plane;

According to the detection time of the posture information and the ambient brightness information, determine the ambient brightness information when the terminal device is at different angles to the vertical direction of the second plane, where the second plane is perpendicular to the first plane;

Generate the brightness of the space where the terminal device is currently located based on the ambient brightness information when the terminal device is at different angles to the vertical direction of the first plane, and the ambient brightness information when the terminal device is at different angles to the vertical direction of the second plane. Model.

In the embodiment of the present disclosure, the attitude detection device and the brightness detection device in the terminal device belong to different detection devices of the terminal device. Therefore, when determining that the terminal device has brightness information under different attitude information, it is necessary to compare the attitude detection device and the brightness detection device. Time synchronization is performed, that is, the posture information detected by the posture detection device at the same time is corresponding to the environmental brightness information detected by the brightness detection device.

Corresponding the attitude information detected by the attitude detection device at the same time with the environment brightness information detected by the brightness detection device includes: corresponding the angle of the terminal device in the vertical direction of the second plane at the same time with the environment brightness information; The angle of the terminal device in the vertical direction of the first plane corresponds to the ambient brightness information.

It should be noted that the brightness model includes environmental brightness information when the terminal device is at different angles to the vertical direction of the first plane, and environmental brightness information when the terminal device is at different angles to the vertical direction of the second plane. It is assumed that the angle between the terminal device and the vertical direction of the first plane can be called up and down; the angle between the terminal device and the vertical direction of the second plane can be called left and right.

As shown in Figure 7, the abscissa is the angle, and the ordinate is the ambient brightness. The curve corresponding to the solid line is the ambient brightness information when the terminal device is at different angles to the vertical direction of the first plane. The curve corresponding to the dotted line is the ambient brightness information when the terminal device is at different angles to the vertical direction of the second plane.

In another embodiment, the reference coordinate system of the terminal device may be the reference coordinate system composed of the rotation axis and the rotation vector direction in the rotation vector sensor of the terminal device. When the first plane is a plane corresponding to the Z-axis direction and the second plane is a plane including X and Y, the ambient brightness information when the terminal device is at different angles to the vertical direction of the first plane may include: the terminal device is along the The environment brightness information when the Z axis is rotated 360 degrees; the environment brightness information when the terminal device is at different angles to the vertical direction of the second plane may include: the environment when the terminal device is rotated 360 degrees along the straight line in the X and Y planes brightness information.

In another embodiment, the brightness model can also be determined based on the ambient brightness information detected by the terminal device when the user rotates around the space, combined with the positioning of the terminal device in the space.

For example, the terminal device is a mobile phone, the casing of the mobile phone is a rectangular casing, the short side of the mobile phone is set parallel to the ground, and the long side of the mobile phone is set perpendicular to the ground. In the actual process of generating the brightness model, you can directly rotate 360 degrees along the short side setting direction of the casing in the terminal device, and record the ambient brightness corresponding to the rotation angle at this time; you can also directly follow the long side of the casing in the terminal device. Set the direction to rotate 360 degrees, and record the ambient brightness corresponding to the rotation angle at this time. In this way, in this way, the ambient brightness information obtained by rotating in two vertical directions can be detected, and the brightness model can be obtained conveniently and quickly.

In one embodiment, compensation information is obtained based on the relative position and brightness model between the terminal device and the light source in the current space, including:

Based on the environmental brightness information in the brightness model, determine the light source type information corresponding to the light source. The light source type information includes the brightness type information of the light source and the luminous angle type information of the light source;

Based on the light source type information, query the compensation model corresponding to the light source type information;

Compensation information is determined based on the relative position between the terminal device and the light source and the compensation model.

In the embodiment of the present disclosure, the environmental brightness information in the brightness model is measured when the terminal device is in different positions under the same light source. Therefore, the brightness type information and the lighting angle type information of the light source can be determined based on the environmental brightness information.

Exemplarily, the brightness type of the light source includes a low-brightness type with a brightness lower than the first threshold or a high-brightness type higher than the first threshold, and the luminous angle type of the light source includes a wide-angle type lower than the second threshold or higher than the second threshold. The narrow angle type of the threshold is not limited in the embodiment of this disclosure.

It can be understood that the brightness corresponding to the low-brightness type light source is lower than the brightness corresponding to the high-brightness type light source; the angle corresponding to the wide-angle type light source is greater than the angle corresponding to the narrow-angle type light source.

In another embodiment, based on the ambient brightness information in the brightness model, the relative position between the light source and the terminal device can also be determined.

For example, assume that the terminal device is a mobile phone, the casing of the mobile phone is a rectangular casing, the short side of the mobile phone is set parallel to the ground, and the long side of the mobile phone is set perpendicular to the ground. If the curve corresponding to the ambient brightness information changes smoothly and slowly when the phone is rotated along the short side of the case, and if the brightness value corresponding to the ambient brightness information changes greatly and steeply when the phone is rotated along the long side of the case, it means The light source is set directly above or directly above and to the right of the mobile phone, and the light source is set relatively high.

It should be noted that under different light source types, users perceive different brightness values of ambient light. For example, when the light source type is a low-brightness type, the brightness value of the ambient light perceived by the user may be 40, and when the light source type is a high-brightness type, the brightness value of the ambient light perceived by the user may be 400. Therefore, embodiments of the present disclosure can query the compensation model corresponding to the light source type information based on the light source type information, and determine the compensation information based on the compensation model.

In the embodiment of the present disclosure, the compensation model is pre-stored on the terminal device. In the process of obtaining the compensation model, the distance between the terminal device and the user is a third threshold, and is obtained through experimental simulation. The compensation model is used to characterize the correspondence between the posture of the terminal device and the compensation information under different light source types.

The above-mentioned third threshold is in the range of 10 cm to 20 cm. The above-mentioned terminal device includes but is not limited to a mobile phone. The size of the mobile phone may be 6 inches or 7 inches, which is not limited in the embodiment of the present disclosure.

The above compensation information may include, but is not limited to, the ratio between the brightness value perceived by the user and the maximum ambient brightness value of the terminal device in the space.

It should be noted that the compensation model corresponds to the light source type, and different light source types correspond to different compensation models.

For example, when the brightness type of the light source includes a low-brightness type or a high-brightness type, and the light-emitting angle type of the light source includes a wide-angle type or a narrow-angle type, the light source type of the terminal device includes a high-brightness wide-angle type, a high-brightness narrow-angle type, There are four light source types: low-brightness wide-angle type and low-brightness narrow-angle type. Correspondingly, the compensation model includes four compensation models: a compensation model corresponding to the high-brightness wide-angle type, a compensation model corresponding to the high-brightness narrow-angle type, a compensation model corresponding to the low-brightness wide-angle type, and a compensation model corresponding to the low-brightness narrow-angle type.

As shown in Figure 8, it is the compensation model corresponding to the highlight wide angle type. As shown in Figure 9, it is the compensation model corresponding to the highlight narrow angle type. As shown in Figure 10, it is the compensation model corresponding to the low-brightness wide-angle type. As shown in Figure 11, it is the compensation model corresponding to the low-brightness narrow-angle type.

In the compensation model corresponding to Figures 8 to 11, the abscissa is the angle, and the ordinate is the ratio between the maximum ambient brightness value and the user-perceived ambient brightness value. The curves corresponding to the solid lines are curves corresponding to different angles between the terminal device and the vertical direction of the first plane, and the curves corresponding to the dotted lines are curves corresponding to different angles between the terminal device and the vertical direction of the second plane.

It can be understood that the corresponding compensation model is queried according to the type information of the light source, and the corresponding compensation information is determined based on different compensation models. In this way, more accurate compensation information can be obtained, which facilitates subsequent accurate adjustment of the brightness of the screen.

In one embodiment, based on the environmental brightness information in the brightness model, the light source type information corresponding to the light source is determined, including:

Obtain the maximum environment brightness information and the minimum environment brightness information in the brightness model;

Based on the maximum environment brightness information and the minimum environment brightness information, the brightness type information of the light source is determined.

In another embodiment, determining the brightness type information of the light source based on the maximum environment brightness information and the minimum environment brightness information includes:

When the ratio between the brightness value corresponding to the maximum environment brightness information and the brightness value corresponding to the minimum environment information is less than or equal to the first threshold, determine the brightness type of the light source to be the first brightness type;

When the ratio between the brightness value corresponding to the maximum environment brightness information and the brightness value corresponding to the minimum environment information is greater than the first threshold, the brightness type of the light source is determined to be the second brightness type.

In the embodiment of the present disclosure, the first threshold can be set according to the actual situation. For example, the first threshold can be set to 6 or 7, which is not limited in the embodiment of the present disclosure. The first brightness type may be a high brightness type, and the second brightness may be a low brightness type.

When the ratio between the brightness value corresponding to the maximum environment brightness information and the brightness value corresponding to the minimum environment information is greater than 6, it indicates that the light source is a high-brightness light source. When the ratio between the brightness value corresponding to the maximum environment brightness information and the brightness value corresponding to the minimum environment information is less than or equal to 6, it indicates that the light source is a low-brightness light source.

For example, as shown in Figure 7, the solid line corresponds to the curve, the maximum ambient brightness corresponding to the solid line is 425, the minimum ambient brightness corresponding to the solid line is 75, and the ratio between the maximum ambient brightness value and the minimum ambient brightness value is greater than 6. From this curve, the corresponding light source type can be obtained as the highlight light source type.

In one embodiment, based on the environmental brightness information in the brightness model, the light source type information corresponding to the light source is determined, including:

Based on the maximum environmental brightness information in the brightness model, determine the half-wave angle information of the light source;

Based on the half-wave angle information of the light source, the luminous angle type information of the light source is determined.

In the embodiment of the present disclosure, the brightness model includes: ambient brightness information when the terminal device is at different angles to the vertical direction of the first plane, which corresponds to the first curve. The brightness model also includes: ambient brightness information when the terminal device is at different angles to the vertical direction of the second plane, which corresponds to the second curve.

The maximum environment brightness information in the above brightness model includes the maximum environment brightness information in the first curve or the maximum environment brightness information in the second curve area.

The half-wave angle of the light source includes a difference between two angles corresponding to half of the maximum ambient brightness information in the first curve or a difference between two angles corresponding to half of the maximum ambient brightness information in the second curve.

In one embodiment, based on the half-wave angle information of the light source, determining the luminous angle type information of the light source includes:

When the half-wave angle of the light source is less than or equal to the second threshold, determine the luminous angle type of the light source to be the first luminous angle type;

When the half-wave angle of the light source is greater than the second threshold, the luminous angle type of the light source is determined to be the second luminous angle type.

For example, the second threshold can be set according to actual needs. For example, the second threshold can be set to 60 degrees or 70 degrees, which is not limited by this embodiment of the disclosure. The first lighting angle type may be a wide angle type, and the second lighting angle may be a narrow angle type.

When the half-wave angle of the light source is less than or equal to 60 degrees, it indicates that the luminous angle type of the light source is a wide-angle type; when the half-wave angle of the light source is greater than 60 degrees, it indicates that the luminous angle type of the light source is a narrow-angle type.

For example, as shown in Figure 7, the maximum ambient brightness value in the curve corresponding to the solid line is 425, and its corresponding half-wave angle is 120 degrees. From this curve, it can be concluded that the corresponding light source type is a wide-angle light source type.

As shown in Figure 7, the size of the light-emitting surface of the light source can be determined by the angle occupied by higher brightness and the angle occupied by lower brightness. For example, 100 degrees is high brightness and 120 degrees is low brightness, indicating that the light source has a larger luminous surface and uniform brightness.

The brightness of the light source can be determined by the difference between the maximum ambient brightness value and the minimum ambient brightness value. For example, if the maximum ambient brightness value is 400 and the minimum ambient brightness value is 40, then the corresponding light source is a light source with that brightness.

The luminous angle of the light source can be determined by whether the change curve from low light to high light is steep or gentle. For example, if the change curve from low brightness to high brightness is steep, it indicates that the luminescence angle is small.

It should be noted that in order to improve the efficiency of the terminal device in generating the brightness model and facilitate the subsequent determination of the light source type from the brightness model, the angle interval can be appropriately increased in the brightness model to reduce the amount of data.

In one embodiment, the compensation information is used to compensate the first environment brightness information detected by the terminal device, and the compensated second environment brightness information is obtained, including:

When the difference between the first environment brightness information detected by the terminal device and the third environment brightness information obtained based on the brightness model of relative position query is outside the preset range, the first environment brightness information is adjusted based on the compensation information and the second environment brightness is obtained information.

When the difference between the first environment brightness information detected by the terminal device and the third environment brightness information obtained by the brightness model based on the relative position query is within the preset range, the maximum environment brightness information in the brightness model is used as the first environment brightness information, And based on the compensation information and the maximum environment brightness information, the second environment brightness information is determined.

It should be noted that when the user actually uses the terminal device, the user may move in the space, and the position of the terminal device in the space will also change accordingly, and the light source is fixed in the space. Therefore, the relative position between the terminal device and the light source is different, and based on the difference in the relative position between the terminal device and the light source, the first environment brightness information and the third environment brightness information detected by the terminal device are also different. It can be seen that when using the compensation information to compensate the first environment brightness information to generate the second environment brightness information, it is necessary to first determine whether the difference between the first environment brightness information and the third environment brightness information is within a preset range.

When the difference between the first environment brightness information and the third environment brightness information is within the preset range, it indicates that the position of the terminal device in the space is the position corresponding to the terminal device in the brightness model, and then the maximum environment brightness information in the brightness model can be used and compensation information to determine second environment brightness information.

When the difference between the first environment brightness information and the third environment brightness information is outside the preset range, it indicates that the terminal device has moved in the space. At this time, it is necessary to adjust the detected first environment brightness information based on the compensation information and obtain the second Ambient brightness information.

For example, if the difference between the first environment brightness information and the third environment brightness information is within a preset range. For the type of light source that is bright and wide-angle, the brightness value corresponding to the maximum ambient brightness information in the brightness model is 430lux, the angle between the terminal device and the vertical direction of the first plane is 60 degrees, and the angle between the terminal device and the second plane The angle between the vertical directions is 60 degrees, that is, the light source is at the upper right side of the terminal device. Based on the compensation model, it can be obtained that the compensation ratios corresponding to the compensation information of the terminal equipment are 63% and 100% respectively. Therefore, the brightness value corresponding to the second environment brightness information is the brightness value corresponding to the maximum environment brightness information multiplied by the compensation ratio corresponding to the compensation information, that is, the brightness value corresponding to the second environment brightness information is 430*63%*100%=270lux.

In one embodiment, adjusting the first environment brightness information based on the compensation information and obtaining the second environment brightness information includes:

Based on the relative position between the terminal device and the light source when detecting the first environment brightness information, query the brightness model to obtain the fourth environment brightness information corresponding to the relative position;

Compare the fourth environment brightness information with the maximum environment brightness information in the brightness model to obtain the compensation coefficient;

The first environment brightness information is adjusted based on the compensation information and the compensation coefficient to obtain the second environment brightness information.

In the embodiment of the present disclosure, when the difference between the first environment brightness information and the third environment brightness information is outside the preset range, it indicates that the terminal device has moved in the space. For example, when the brightness model is generated, the user chooses to stand, and later the user chooses to lie down, which causes the position of the terminal device in the space to change. Due to different positions, the maximum ambient brightness of the terminal device corresponding to the position in the brightness model may lead to inaccurate screen brightness adjustment. Therefore, when the position of the terminal device changes, a compensation coefficient needs to be obtained to compensate for the position change. Compensation is performed based on the detected environment brightness information of the terminal device.

In the embodiment of the present disclosure, the fourth environment brightness information is compared with the maximum environment brightness information in the brightness model, and the compensation coefficient obtained includes: the brightness value corresponding to the fourth environment brightness information and the brightness value corresponding to the maximum environment brightness information in the brightness model. The ratio between them is used to obtain the compensation coefficient.

After obtaining the compensation coefficient, the first environment brightness information is adjusted based on the compensation information and the compensation coefficient to obtain the second environment brightness information, including: determining the maximum environment brightness information after compensation based on the ratio of the first environment brightness information and the compensation coefficient. ; Determine the second environment brightness information based on the brightness value corresponding to the compensated maximum environment brightness information and the compensation information.

For example, if the calibration results in a curve corresponding to the solid line shown in Figure 7, the curve corresponds to a bright wide-angle type light source. When generating the brightness model, the terminal device is placed vertically, and the relative position between the terminal device and the light source is 120 degrees on the up and down axis and 240 degrees on the left and right. Later, the user chooses to lie down and use the terminal device. The relative position between the terminal device and the light source is -60 degrees on the up and down axis, and -60 degrees on the left and right rotation. At this time, the reading of the light sensor on the terminal device is 37lux, which is the first ambient brightness information. The corresponding brightness value is 37lux. Through the first environment brightness information and the curve, the compensation coefficients can be obtained as 0.45 and 0.26, and then the brightness value corresponding to the compensated maximum brightness information is 37/0.45/0.26=316lux. The compensation ratio corresponding to the compensation information is 63%*100%=63%. Then the second environment brightness information at this time is 316*63%=200lux.

Therefore, the screen brightness of the terminal device should be adjusted according to the brightness value corresponding to the second environment brightness information, which is 200lux, rather than the 37lux measured by the light sensor. It can be seen that by adjusting the screen brightness through the brightness adjustment method proposed in the embodiment of the present disclosure, the screen brightness can be adjusted more accurately without changing the existing light sensor hardware, thereby improving the user experience.

In order to facilitate a better understanding of the embodiments of the present disclosure, the following examples are provided. As shown in Figure 12, the adjustment methods of screen brightness include:

Step S21: Detect the posture information of the terminal device based on the prompt information, and detect the environmental brightness information of the terminal device in different postures;

Step S22: Generate and store a brightness model based on the posture information and the environment brightness information;

Step S23: Determine the light source type information corresponding to the light source based on the environmental brightness information in the brightness model;

Step S24: Based on the light source type information, query the compensation model corresponding to the light source type information;

Step S25: Determine compensation information based on the relative position between the terminal device and the light source and the compensation model.

Step S26: When the difference between the first environment brightness information detected by the terminal device and the third environment brightness information obtained by the brightness model based on the relative position query is within the preset range, use the maximum environment brightness information in the brightness model as the first environment. brightness information, and determine the second environment brightness information based on the compensation information and the maximum environment brightness information.

Step S27: When the difference between the first environment brightness information detected by the terminal device and the third environment brightness information obtained based on the brightness model of relative position query is outside the preset range, adjust the first environment brightness information based on the compensation information and obtain the third environment brightness information. 2.
