Several specific embodiments are given below to introduce the technical solutions of the present disclosure in detail. The following specific embodiments may be combined, and the same or similar concepts will not be repeated in some embodiments.

FIG. 1 is a flowchart of a method for adjusting backlight brightness according to an exemplary embodiment of the present disclosure. Referring to FIG. 1, the method provided by this embodiment may include the following steps:

S101. Acquire a target adjustment parameter sequence corresponding to the target brightness mode in response to an operation of selecting a target brightness mode from multiple pre-configured brightness modes.

It should be noted that the operation of selecting the target brightness mode from the pre-configured multiple brightness modes can be triggered by the user, or sent by the other device to the electronic device after the user triggers the operation in another device. In this embodiment, this is not limited.

Further, the electronic device may provide a brightness mode selection control on the brightness setting page. Further, the electronic device may display a plurality of preconfigured brightness modes to the user in response to the brightness mode selection control being triggered. In addition, pre-configured multiple brightness modes are configured according to actual needs. In this embodiment, it is not limited. For example, in one embodiment, the pre-configured multiple brightness modes include: high light, low light, standard, dark, custom 1, custom 2.

In addition, the pre-configured multiple brightness modes may be configured in the electronic device when the electronic device leaves the factory; and/or, the pre-configured multiple brightness modes are configured in the electronic device based on a user's brightness mode configuration operation. In the electronic device; and/or, the pre-configured brightness modes are obtained from other electronic devices independent of the electronic device and configured in the electronic device (for example, the user can obtain from the server that manages the electronic device). Obtain the configured brightness mode (for example, the service provider can periodically update the brightness mode on the server, and the user can obtain the brightness mode from the server based on their own needs), or obtain the configured brightness mode from the electronic devices of other users ( For example, after user A configures a brightness mode on his mobile phone A, the brightness mode can be shared with user B)).

For example, in the above-mentioned example, the first four brightness modes (high light, low light, standard, and dark) may be configured in the electronic device when the electronic device leaves the factory, and the latter two brightness modes (custom 1 and The customization 2) may be configured in the electronic device based on the user's configuration operation.

It should be noted that each brightness mode corresponds to an adjustment parameter sequence, and the adjustment parameter sequence is used to correct the standard brightness curve to obtain the corrected target brightness curve. In addition, an adjustment parameter sequence includes T (T is a positive integer smaller than N, and N is the length of the first value sequence of screen brightness in the mapping relationship between standard ambient light brightness and screen brightness (the length of the value sequence refers to is the number of numeric elements contained in the value sequence)) numeric elements, each of which is a natural number.

In the present disclosure, by configuring different brightness modes, in this way, the standard brightness curve can be adjusted based on different adjustment parameter sequences, so as to obtain a target brightness curve that can meet the needs of different users.

In addition, after a brightness mode is configured, the electronic device will store the identifier of the brightness mode in association with the adjustment parameters corresponding to the brightness mode. In this step, in response to the user's operation of selecting a target brightness mode from multiple brightness modes, a target adjustment parameter sequence corresponding to the target brightness mode can be obtained based on the identifier of the target brightness mode.

S102 , using the target adjustment parameter sequence as a convolution kernel, and correcting a pre-stored standard brightness curve based on a convolution operation to obtain a corrected target brightness curve.

Specifically, in an embodiment, the standard brightness curve may include a mapping relationship between standard ambient light brightness and screen brightness, and a mapping relationship between standard screen brightness and backlight level. At this time, the specific implementation process of this step may include:

(1) Using the target adjustment parameter sequence as the convolution kernel, based on the convolution operation, the first mapping relationship between the standard ambient light brightness and the screen brightness in the pre-stored standard brightness curve is corrected, and the corrected first mapping relationship is obtained. Mapping relations.

FIG. 2 is a flowchart of another backlight brightness adjustment method according to an exemplary embodiment of the present disclosure. Please refer to FIG. 2. In the example shown in FIG. 2, the specific implementation process of this step may include:

S201. Obtain a first value sequence of screen brightness in the first mapping relationship between the standard ambient light brightness and screen brightness.

For example, in one embodiment, the first mapping relationship between the standard ambient light brightness and the screen brightness can be represented by two digital element sequences, where the two digital element sequences are:

The second value sequence of ambient light intensity: contains N-1 increasing positive numbers; wherein, each digital element is used as an ambient light intensity interval point, and N-1 digital elements divide the ambient light intensity into N intervals.

The first value sequence of screen brightness: contains N increasing positive numbers (that is, the length of the first value sequence is N); each digital element represents the minimum screen brightness value corresponding to the ambient light brightness interval.

In combination with the above introduction, for example, in an embodiment, the second value sequence includes 4 digital elements, and the 4 digital elements are: H1, H2, H3, and H4; the first value sequence includes 5 digital elements, The five digital elements are: A, B, C, D and E (when the ambient light brightness interval is (0H1), the corresponding minimum screen brightness value is A). At this time, in this step, the obtained first A value sequence is a sequence of digital elements composed of A, B, C, D, and E.

S202. Perform a convolution operation on the first value sequence using the target adjustment parameter sequence as a convolution check to obtain a target value sequence; wherein the length of the target value sequence is equal to the length of the first value sequence length.

During specific implementation, the first value sequence may be filled according to the target adjustment parameter sequence to obtain a filled value sequence, and then the filled value sequence may be used as a convolution check to check the filled value sequence. The value sequence is subjected to a convolution operation to obtain the target value sequence.

During the specific filling, zero can be used as the filling value for filling, or the average value of each digital element in the target adjustment parameter sequence can be used as the filling value, or the last value in the target adjustment parameter sequence can be used for filling. A numeric element is filled as the padding value. In addition, when filling, M (M is equal to the difference between the length T of the target adjustment parameter sequence and 1) filling values need to be filled to the end of the first value sequence to obtain a filled value sequence.

For example, in one embodiment, the target adjustment parameter sequence includes three digital elements, and the three digital elements are T1, T2, and T3, respectively. Combined with the above example, the first value sequence is a sequence of digital elements composed of A, B, C, D, and E. In this case, two padding values need to be filled at the end of the first value sequence. For example, in an embodiment, zero is used as the padding value for padding, and the value sequence after padding is: A, B, C, D, E, 0, 0.

Further, the process of convolution operation can be expressed as follows:

Among them, Y _n is the element in the target value sequence;

Ja is an element in the convolution kernel, c represents the length of the convolution kernel, and b represents the step size of the convolution kernel movement (in the present disclosure, the step size of the convolution kernel movement is 1);

X _(a+(n-1)b) is an element in the filled value sequence.

For example, in one embodiment, the convolution kernel includes three elements (the length of the convolution kernel is 3), which are denoted as J1, J2, and J3, respectively, and the filled value sequence includes 7 elements, denoted as X1 to X7, respectively. , each element in the target value sequence is denoted as Y1 to Y5, respectively: Y1=J1*X1+J2*X2+J3*X3, Y2=J1*X2+J2*X3+J3*X4, Y3=J1* X3+J2*X4+J3*X5, Y4=J1*X4+J2*X5+J3*X6, Y5=J1*X5+J2*X6+J3*X7

Combined with the above introduction, in the above example, after obtaining the padded value sequence, T1, T2 and T3 can be used as convolution kernels to perform convolution operation on the padded value sequence to obtain the target value sequence. For the specific implementation principle of the convolution operation, reference may be made to the foregoing description, which will not be repeated here. In this example, after the convolution operation, the obtained target value sequence is A*T1+B*T2+C*T3, B*T1+C*T2+D*T3, C*T1+D*T2+E* A sequence of digital elements consisting of T3, D*T1+E*T2+0*T3, and E*T1+0*T2+0*T3.

S203. Construct the modified first mapping relationship based on the target value sequence and the second value sequence of ambient light brightness in the first mapping relationship.

In specific implementation, the second value sequence is used as the value sequence of ambient light brightness in the revised first mapping relationship, and the target value sequence is used as the corresponding screen brightness value sequence in the mapping relationship to construct the revised The first mapping relationship.

Combining the above example, the constructed first mapping relationship after correction can be expressed as the corresponding relationship between the following two sequence of digital elements (see the following two sequences of digital elements, that is, when the ambient light brightness interval is (0H1), the corresponding minimum The screen brightness value is A*T1+B*T2+C*T3):

Value sequence of ambient light intensity: H1, H2, H3 and H4

The value sequence of screen brightness: A*T1+B*T2+C*T3, B*T1+C*T2+D*T3, C*T1+D*T2+E*T3, D*T1+E*T2 +0*T3, E*T1+0*T2+0*T3

Referring to the previous description, by adjusting the parameter sequence, the mapping relationship between ambient light intensity and screen brightness can be adjusted. In addition, different visual effects can be achieved by setting different adjustment parameter sequences.

For example, the multiple adjustment parameter sequences corresponding to the multiple brightness modes include a first type of adjustment parameter sequence for performing linear adjustment on the standard brightness curve and a second type of adjustment for performing nonlinear adjustment on the standard brightness curve parameter sequence.

It should be noted that, in the first type of adjustment parameter sequence, except for the first digital element which is not 0, other digital elements are all 0. For example, a first-type adjustment parameter sequence may be A1 (greater than 0), 0, 0. Further, A1 can be set to a positive number less than 1 to achieve the purpose of lowering the standard brightness curve (the corresponding screen brightness is darker), or A1 can be set to a positive number greater than 1 to achieve a higher standard brightness curve. purpose (the corresponding screen brightness is brighter). In addition, the second type of adjustment parameter sequence includes at least one non-zero number element except that the first number element is not 0.

(2) Constructing the target brightness curve based on the modified first mapping relationship and the second mapping relationship between the standard screen brightness and the backlight level in the standard brightness curve.

Specifically, the corrected first mapping relationship and the second mapping relationship between the standard screen brightness and the backlight level in the target standard brightness curve can be directly determined as the target brightness curve.

S103. Adjust the backlight brightness of the electronic device based on the target brightness curve.

The specific implementation process of this step may include: detecting ambient light brightness, determining a target backlight level corresponding to the ambient light brightness based on the ambient light brightness and a target brightness curve, and then adjusting the backlight brightness based on the target backlight level.

In this way, since the target brightness curve is a brightness curve obtained by modifying the standard brightness curve based on the target adjustment parameter corresponding to the target brightness mode selected by the user, in this way, by providing multiple brightness modes, a variety of brightness curves can be provided to the user. You can choose an appropriate brightness curve according to your own needs, which can meet the viewing needs of different users, improve the adjustment accuracy, and improve the user's viewing experience.

For example, in an embodiment, the specific content of the configuration description may be: you can input no more than N (N is the length of the first value sequence above) digital elements, so that the digital element sequence pair formed by the input digital elements The standard brightness curve is corrected. If you want to increase the standard brightness curve, you can input T (less than the above N) numbers greater than 1 to form a digital element sequence. If you want to lower the standard brightness curve, you can input T numbers less than 1 to form a digital element sequence.
