Referring to FIG. 2 , an embodiment of the present invention provides a method for adjusting screen brightness, and the method may include the following steps 201 - 203 .

Step 201, the terminal device acquires an adjustment parameter, where the adjustment parameter at least includes the ambient light brightness of the environment where the terminal device is located.

Ambient luminance is usually expressed by illuminance, that is, the illuminance produced by the uniform distribution of ¹ lumen (lm) of luminous flux on a 1m2 surface, unit lux, symbol lx; ambient luminance can also be expressed by luminous intensity per unit projected area, unit It is candela/square meter (cd/m ² ); the ambient light brightness can also be represented by other expressions, which are not limited in this embodiment of the present invention.

Exemplarily, the system time of the terminal device is the current time collected by the terminal device.

Exemplarily, the user ID is used to identify different users, wherein, if the user ID is a user account, when the user starts to use the terminal device each time, the user enters the user's account; if the user ID is the user's password, when the user When starting to use the terminal device for the first time, input the user's user password; if the user ID is the user's fingerprint information, then when the user starts using the terminal device each time, input the user's fingerprint information in the fingerprint collection area of the terminal device; if the user The identification is one of the user's facial information, user's iris information, user's hand shape information, and user's retinal information. Then when the user starts to use the terminal device every time, the terminal device can correspondingly capture the user's facial image through the camera, and the user's An image of the iris of the user, an image of the user's hand, and an image of the user's retina. The terminal device identifies the user currently using the terminal device according to the user identifier.

Exemplarily, the geographic location information of the terminal device may be latitude and longitude information of the terminal device. Optionally, the terminal device may be positioned through the Global Positioning System (GPS for short), base station positioning, Wireless Fidelity (Wi-Fi for short) positioning, Internet Protocol (Internet Protocol, IP for short) positioning , radio frequency identification (Radio Frequency Identification, referred to as RFID)/QR code, Bluetooth positioning and other positioning methods to obtain the geographic location information of the current location of the terminal device. The specific positioning technology for realizing the above positioning methods can refer to existing related technology, and will not be described in detail in the embodiments of the present invention.

Exemplarily, the first indication information may use 0 to represent non-indoor, and 1 to represent indoor. The terminal device can determine whether the terminal device is located indoors by taking pictures with the camera.

Exemplarily, in the embodiment of the present invention, the conditions for triggering the terminal device to adjust the screen brightness according to the screen brightness adjustment method provided in the embodiment of the present invention may be any of the following: the terminal device periodically triggers the terminal device to perform screen brightness adjustment. Brightness adjustment: when the terminal device detects that the change of at least one of the adjustment parameters satisfies a corresponding condition, the terminal device is triggered to adjust the screen brightness. Exemplarily, when the terminal device detects that the change in ambient light brightness is greater than or equal to the first threshold, the terminal device is triggered to adjust the screen brightness; when the terminal device detects that the system time of the terminal device is greater than or equal to the first preset time When the terminal device detects that the user ID has changed, it triggers the terminal device to adjust the screen brightness; when the terminal device detects that the geographic location information of the terminal device has changed within the preset time period When the change is greater than or equal to the second threshold, the terminal device is triggered to adjust the screen brightness; when the terminal device detects the change of the terminal device from indoor to outdoor or from outdoor to indoor, it triggers the terminal device to adjust the screen brightness; It is other conditions that trigger the terminal device to adjust the screen brightness, which is not limited in this embodiment of the present invention.

Step 202, the terminal device calculates a first brightness value according to the adjustment parameter and the brightness value calculation model.

The brightness value calculation model is generated according to historical sample data of the user using the terminal device.

The luminance value calculation model can be a fixed model generated based on historical sample data, or a model that is constantly changing with the increase of historical sample data, which is specifically set according to the actual situation, and is not limited by the embodiment of the present invention . If the brightness value calculation model is a model that is constantly changing with the increase of historical sample data, then with the increase of sample data and the immobilization of user behavior habits, the first brightness calculated according to the brightness value calculation model can be The value is more and more in line with the user's needs. At this time, the brightness value calculation model can be generated in real time, or it can be generated in advance at any time from the last time the terminal device completes the screen brightness adjustment to the time before the terminal device is triggered to adjust the screen brightness. The actual situation is set, and the embodiment of the present invention does not make a limitation.

Step 203, the terminal device adjusts the brightness value of the screen to the first brightness value.

The first brightness value calculated by the terminal device is a brightness value that better meets the user's needs at present, so if the brightness value of the screen is not the first brightness value, the terminal device adjusts the brightness value of the screen to the first brightness value .

After the terminal device adjusts the brightness value of the screen to the first brightness value, that is, after the screen brightness is automatically adjusted this time, the terminal device saves the adjustment parameters used to calculate the first brightness value as a piece of sample data, and can also save the The brightness value before this adjustment and the first brightness value are stored in the piece of sample data, so as to be used to calculate the brightness value calculation model for the next adjustment.

Exemplarily, referring to FIG. 2 , as shown in FIG. 3 , before step 202 , the screen brightness adjustment method provided by the embodiment of the present invention may further include the following steps 204 - 205 .

Step 204, the terminal device acquires the historical sample data.

The historical sample data includes N pieces of sample data, each piece of sample data in the N pieces of sample data includes at least one ambient light brightness, and each piece of sample data in the M pieces of sample data includes a second brightness value and a third brightness value, the The third brightness value is the brightness value after adjusting the second brightness value according to the user's input, that is, the second brightness value is the brightness value before the user manually adjusts the screen brightness, and the third brightness value is the brightness after the user manually adjusts the screen brightness value, the M pieces of sample data are sample data in the N pieces of sample data, N and M are both positive integers, and N is greater than or equal to M.

Each piece of historical sample data in the N pieces of sample data may also include at least one of the following: historical time of the terminal device, historical user ID, historical geographic location information of the terminal device, and historical first indication information, etc., Others may also be included, which is not limited in the embodiment of the present invention; wherein, the historical user identification is at least one of the following: account number of historical user, password of historical user, fingerprint information of historical user, facial information of historical user, historical The user's iris information, historical user's hand shape information, historical user's retinal information, etc. may also include others, which are not limited in this embodiment of the present invention; the historical first indication information is used to indicate whether the terminal device is historically located indoors. For specific descriptions of the terminal device's historical time, historical user ID, historical geographic location information of the terminal device, and historical first indication information, you can refer to the above-mentioned system time, user ID, and information about the terminal device. Relevant descriptions of the geographic location information and the first indication information will not be repeated here.

Step 205, the terminal device generates the luminance value calculation model according to the historical sample data and the machine learning algorithm model.

The machine learning algorithm model may be any machine learning algorithm model in the prior art, which is not limited in this embodiment of the present invention. For example, it can be a logistic regression algorithm model, a naive Bayesian classifier algorithm model, a K-means clustering algorithm model, a K-nearest neighbor algorithm model, a support vector machine learning algorithm model, a linear regression machine learning algorithm model, a decision tree machine learning algorithm model , Random Forest Machine Learning Algorithm Model, Neural Network Algorithm Model, etc. For details, please refer to existing related technologies. The method for adjusting screen brightness provided by the embodiment of the present invention is exemplarily described below by taking a logistic regression algorithm model as an example.

The formula of the logistic regression algorithm model is as follows:

(1) θ ^T x = θ ₀ + θ ₁ x ₁ + θ ₂ x ₂ +... + θ _n x _n

(3) h _θ (x) = g(θ ^T x)

From the formulas (1), (2) and (3), the logistic regression algorithm model formula can be obtained:

in, is the Sigmoid function, h _θ (x) is the percentage of the final predicted brightness value, and n is the number of items of the adjustment parameter or the number of items of each piece of sample data. θ _n is the coefficient of the logistic regression model calculated based on historical sample data, and x _n is one of the adjustment parameters.

For details on how to calculate the coefficient θ _n of the logistic regression algorithm model based on historical sample data, reference may be made to existing related technologies, which will not be repeated here.

When the brightness value calculation model is a logistic regression algorithm model, the first brightness value is the product of h _θ (x) and 255.

Exemplarily, referring to FIG. 3 , as shown in FIG. 4 , after step 203 , the screen brightness adjustment method provided by the embodiment of the present invention may further include the following steps 206 - 207 .

Step 206, the terminal device receives a first input from the user on the brightness adjustment interface in the terminal device.

The first input is an input for the user to manually adjust the brightness of the screen. The first input may be a sliding input, a dragging input, a clicking input, etc., which are not limited in this embodiment of the present invention.

If the user is not satisfied with the automatically adjusted screen brightness value (the first brightness value), the user can further adjust it manually until the user is satisfied.

After step 203, the terminal device can automatically display the brightness adjustment interface so that the user can manually adjust the brightness and improve user experience, or the user can trigger the terminal device to display the brightness adjustment interface through a third input, which is set according to the actual situation. Examples are not limited.

If the terminal device automatically displays the brightness adjustment interface, if the terminal device receives a fourth input from the user on the brightness adjustment interface within a preset time period, then in response to the fourth input, the terminal device performs an operation corresponding to the fourth input , where the fourth input can be the first input. If the terminal device does not receive any input from the user on the brightness adjustment interface within the preset time period, the terminal device hides the brightness adjustment interface. Or if the user does not want to use the brightness adjustment interface to hide, then click on a location other than the brightness adjustment interface to trigger the terminal device to hide the brightness adjustment interface.

Exemplarily, the brightness adjustment interface can be superimposed and displayed at any position on the current interface of the terminal device, and the transparency of the brightness adjustment interface is any value between 0 and 100%, which can be set according to actual needs. The embodiments of the present invention Not limited. Preferably, the brightness adjustment interface is superimposed and displayed below the current interface of the terminal device, which is convenient for operation; the transparency of the brightness adjustment interface is 100%. This will not affect the user viewing the current interface.

Exemplarily, as shown in FIG. 5 , the brightness adjustment interface may include a setting shortcut key, a brightness adjustment slide bar, and a brightness fixed key. The setting shortcut key is the setting shortcut key on the main interface of the terminal device. In order to facilitate the setting of the automatic brightness adjustment function, the setting shortcut key is also set on the brightness adjustment interface. The brightness adjustment slide bar is used to manually adjust the screen brightness value, and the brightness adjustment slide bar can also be replaced with a brightness adjustment scroll bar, or it can be replaced with a brightness adjustment "+" and "-" key. The brightness fixed key is used for the user to quickly turn off the automatic adjustment function of the screen brightness.

Step 207: In response to the first input, the terminal device adjusts the brightness value of the screen from the first brightness value to a fourth brightness value corresponding to the first input.

The fourth brightness value corresponding to the first input is the brightness value of the screen after the user manually adjusts the brightness of the screen.

Exemplarily, referring to FIG. 4 , as shown in FIG. 6 , after step 207 , the screen brightness adjustment method provided by the embodiment of the present invention may further include the following step 208 .

Step 208, the terminal device saves the adjustment parameter, the first brightness value and the fourth brightness value as a piece of sample data.

In order to facilitate the brightness value obtained by the next automatic screen brightness adjustment to be closer to the user's needs, the brightness value before and after the user's manual adjustment is saved.

It should be noted that: after step 203, the terminal device has already saved the adjustment parameter as a piece of sample data, so here the first brightness value and the fourth brightness value can be saved in the piece of sample data where the adjustment parameter is saved .

Exemplarily, the brightness adjustment interface in the terminal device includes a target control, the brightness adjustment interface is the brightness adjustment interface in step 206, and the target control is the brightness fixed key mentioned above. Referring to FIG. 2 , as shown in FIG. 7 , after step 203 , the screen brightness adjustment method provided by the embodiment of the present invention may further include the following steps 209 - 210 .

Step 209, the terminal device receives a second input from the user on the target control, and the second input is used to trigger the terminal device to turn off the function of automatically adjusting screen brightness.

Exemplarily, in some environments where the brightness of the ambient light is constantly changing (for example, in a KTV), the terminal device may automatically adjust the screen brightness value continuously, causing the user to be unable to use the mobile phone normally. Therefore, the user can click the The target control, thereby triggering the terminal device to turn off the function of automatically adjusting the screen brightness.

When the user wants to enable the screen brightness adjustment function, he can click the target control again.

Step 210, in response to the second input, the terminal device controls the brightness value of the screen to remain at the first brightness value.

In response to the second input, the terminal device disables the function of automatically adjusting the brightness of the screen, and controls the brightness value of the screen to remain at the first brightness value. The only thing here is that the terminal device cannot automatically adjust the screen brightness, and the user can also adjust the screen brightness.

As an example, as a terminal device user who is sensitive to brightness, we can predict the brightness value that the user is satisfied with in different environments by combining his daily behavior feedback and ambient light brightness, and make real-time follow-up behavior Adjust to effectively improve user experience and protect their eyesight.

For example, a sensitive user encounters a scene where the screen brightness is automatically adjusted during normal use. After the screen brightness value is automatically adjusted, if the brightness value reaches 60, the user feels that the brightness value is too bright, and the user cannot adapt to it. Time watching is more harmful to the eyes. Therefore, he manually dims the brightness and adjusts the brightness value to about 40. At this time, the terminal device collects the brightness value before and after the manual adjustment by the user, and saves it in the sample data. When the brightness adjustment function is triggered in the same type of use scene next time, the solution in the prior art will still give the same adjustment result, that is, about 60. However, the solution provided by the embodiment of the present invention predicts the brightness based on the learning results of historical samples, and the result is about 50, which avoids manual adjustment by the user again, and subtly improves the user experience.

It should be noted that the screen brightness adjustment method provided by the embodiment of the present invention can effectively provide users with brightness values that meet their needs only when there is enough historical sample data. Whether the historical sample data is sufficient is determined according to the requirements of the selected machine learning algorithm model. For details, refer to the prior art, which is not limited in the embodiment of the present invention. In the case of less historical sample data, the terminal device can adjust the screen brightness according to the screen brightness adjustment method provided by the prior art, and then if the user is not satisfied, the user can manually adjust it. After each adjustment is completed, the terminal device collects the adjustment parameters of this adjustment and the brightness values before and after manual adjustment by the user, and saves them as a piece of sample data. When there is enough sample data, the terminal device adjusts the screen brightness according to the method for adjusting screen brightness provided by the embodiment of the present invention.

An embodiment of the present invention provides a method for adjusting screen brightness. By obtaining an adjustment parameter, the adjustment parameter includes at least the ambient light brightness of the environment where the terminal device is located; and calculating the first brightness value according to the adjustment parameter and the brightness value calculation model, The brightness value calculation model is generated according to the historical sample data of the user using the terminal device; if the brightness value of the screen is not the first brightness value, the brightness value of the screen is adjusted to the first brightness value. This solution can calculate the first brightness value according to the adjustment parameters and the brightness value calculation model, wherein the brightness value calculation model is generated according to the historical sample data of the user using the terminal device, so that compared with the prior art, this solution can construct The different needs of different users are obtained according to the historical sample data of different users, and then different brightness values are automatically adjusted for the screens of different users according to the different needs of different users. Furthermore, the problem that the prior art method of automatically adjusting the screen brightness according to the ambient light intensity cannot meet the different needs of different users for the screen brightness can be solved.
