Thus, the requirements of different users on eye viewing can be met, and the adjustment precision is improved.
The following detailed embodiments are provided to describe the technical solution of the present disclosure in detail, and may be combined, and the details of the same or similar concepts will not be repeated in some embodiments.
Fig. 1 is a flowchart of a backlight brightness adjustment method according to an exemplary embodiment of the present disclosure. Referring to fig. 1, the method provided in this embodiment may include the following steps:
S101, responding to an operation of selecting a target brightness mode from a plurality of preset brightness modes, and acquiring a target adjustment parameter sequence corresponding to the target brightness mode.
It should be noted that, the operation of selecting the target brightness mode from the preconfigured plurality of brightness modes may be triggered by the user, or after the user triggers the operation in the other device, the other device sends the operation to the electronic device. In the present embodiment, this is not limited.
Further, the electronic device can provide a brightness mode selection control on the brightness setting page. Further, the electronic device can present a preconfigured plurality of brightness modes to a user in response to the brightness mode selection control being triggered. In addition, a plurality of luminance modes configured in advance are configured according to actual needs. In this embodiment, this is not limited. For example, in one embodiment, the preconfigured plurality of brightness modes includes: highlighting, low-lighting, standard, dark, custom 1, custom 2.
Further, the plurality of luminance modes configured in advance may be configured in the electronic device at the time of shipment of the electronic device; and/or, the preconfigured plurality of brightness modes are configured in the electronic device based on a brightness mode configuration operation of the user; and/or, the preconfigured multiple brightness modes are obtained from other electronic devices independent of the electronic device and configured in the electronic device (for example, a user can obtain the configured brightness mode from a server for managing the electronic device (for example, a server can periodically update the brightness mode on the server, a user can obtain the brightness mode from the server based on own demand), or obtain the configured brightness mode from the electronic device of other users (for example, after a user a configures one brightness mode on an a mobile phone used by the user a, the brightness mode can be shared to a user B)).
For example, in the above-described example, the first four luminance patterns (highlight, low-highlight, standard, dark) may be configured in the electronic device at the time of shipment of the electronic device, and the second two luminance patterns (custom 1 and custom 2) may be configured in the electronic device based on the configuration operation of the user.
It should be noted that, each brightness mode corresponds to an adjustment parameter sequence, and the adjustment parameter sequence is used for correcting the standard brightness curve to obtain a corrected target brightness curve. In addition, one adjustment parameter sequence includes T (T is a positive integer smaller than N, N is a length of a first value sequence of screen brightness in a mapping relationship between standard ambient light brightness and screen brightness (the length of the value sequence refers to the number of digital elements included in the value sequence)), and each digital element is a natural number.
In the disclosure, different brightness modes are configured, so that the standard brightness curve can be adjusted based on different adjusting parameter sequences, and the target brightness curve which can meet different user requirements is obtained.
In addition, after a brightness mode is configured, the electronic device can store the identification of the brightness mode and the adjustment parameters corresponding to the brightness mode in a correlated manner. In this step, in response to a user selecting a target luminance mode from a plurality of luminance modes, a target adjustment parameter sequence corresponding to the target luminance mode may be obtained based on an identification of the target luminance mode.
S102, correcting a pre-stored standard brightness curve based on convolution operation by taking the target adjustment parameter sequence as a convolution kernel to obtain a corrected target brightness curve.
Specifically, in one embodiment, the standard luminance curve may include a mapping relationship between standard ambient light luminance and screen luminance, and a mapping relationship between standard screen luminance and backlight level. At this time, the specific implementation procedure of this step may include:
(1) And correcting the first mapping relation between the standard ambient light brightness and the screen brightness in the pre-stored standard brightness curve based on convolution operation by taking the target adjustment parameter sequence as a convolution kernel to obtain a corrected first mapping relation.
Fig. 2 is a flowchart of another backlight brightness adjustment method according to an exemplary embodiment of the present disclosure. Referring to fig. 2, in the example shown in fig. 2, the specific implementation procedure of this step may include:
S201, acquiring a first value sequence of the screen brightness in a first mapping relation between the standard ambient light brightness and the screen brightness.
For example, in one embodiment, the first mapping relationship between the standard ambient light brightness and the screen brightness can be characterized by two digital element sequences, where the two digital element sequences are respectively:
a second sequence of values of the intensity of the ambient light: containing N-1 increasing positive numbers; wherein each digital element is used as an ambient light intensity interval point, and the N-1 digital element divides the ambient light intensity into N intervals.
First value sequence of screen brightness: comprises N incremental positive numbers (namely, the length of the first value sequence is N); each digital element represents a minimum screen brightness value for the corresponding ambient light intensity interval.
In connection with the above description, for example, in one embodiment, the second sequence of values includes 4 digital elements, which are respectively: h1, H2, H3, and H4; the first sequence of values comprises 5 digital elements, the 5 digital elements being: A. b, C, D and E (when the ambient light brightness interval is (0H 1), the corresponding minimum screen brightness value is A.) at this time, the first value sequence obtained in this step is a digital element sequence composed of A, B, C, D and E.
S202, performing convolution operation on the first value sequence by taking the target adjustment parameter sequence as a convolution check to obtain a target value sequence; the length of the target value sequence is equal to the length of the first value sequence.
In the 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 is subjected to convolution operation by taking the target adjustment parameter sequence as a convolution check to obtain the target value sequence.
In the specific filling, zero may be used as a filling value for filling, or an average value of each digital element in the target adjustment parameter sequence is used as a filling value for filling, or a last digital element in the target adjustment parameter sequence is used as a filling value for filling. In addition, during 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, so as to obtain a filled value sequence.
For example, in one embodiment, the target adjustment parameter sequence includes 3 digital elements, which are T1, T2, and T3, respectively. In combination with the above example, the first sequence of values is a sequence of numerical elements consisting of A, B, C, D and E. At this time, 2 padding values need to be padded at the end of the first valued sequence. For example, in one embodiment, zero is used as a filling value to fill, and the value sequence after filling is: A. b, C, D, E, 0.
Further, the convolution operation can be expressed as follows:
Wherein Y n is an element in the target value sequence;
Ja is an element in the convolution kernel, c represents the length of the convolution kernel, b represents the step size of the convolution kernel movement (in this 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 (length of the convolution kernel is 3), denoted as J1, J2, and J3, respectively, the filled value sequence includes 7 elements, denoted as X1 through X7, respectively, and each element in the target value sequence is denoted as Y1 through 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
In combination with the above description, in the above example, after the filled value sequence is obtained, the filled value sequences may be subjected to convolution operation by using the T1, T2, and T3 as convolution cores, to obtain the target value sequence. The specific implementation principle of the convolution operation can be referred to in the foregoing description, and will not be repeated here. In this example, the target value sequence obtained after convolution operation is a digital element sequence consisting of a1+bt2+ct3, bt1+ct2+dt3, ct1+dt2+et3, dt1+et2+0 t3, et1+0 t2+0 t3.
S203, constructing the corrected first mapping relation based on the target value sequence and a second value sequence of the ambient light brightness in the first mapping relation.
In specific implementation, the second value sequence is used as the value sequence of the ambient light brightness in the corrected first mapping relation, and the target value sequence is used as the corresponding screen brightness value sequence in the mapping relation to construct the corrected first mapping relation.
In combination with the above example, the first mapping relationship after correction may be expressed as a correspondence relationship between the following two digital element sequences (see the following two digital element sequences, that is, when the ambient light brightness interval is (0H 1), the corresponding minimum screen brightness value is a×t1+b×t2+c×t3):
sequence of values of the intensity of the ambient light: h1, H2, H3 and H4
Value sequence of screen brightness: aT1+bT2+cT3, bT1+cT2+dT3, cT1+dT2+ET3, dT1+ET2+0 T3, ET1+0T2+0 T3
With reference to the foregoing description, the mapping relationship between the ambient light intensity and the screen brightness can be adjusted by adjusting the parameter sequence. In addition, different visual effects can be achieved by setting different adjustment parameter sequences.
For example, the plurality of adjustment parameter sequences corresponding to the plurality of luminance modes include a first type of adjustment parameter sequence for linearly adjusting the standard luminance curve and a second type of adjustment parameter sequence for non-linearly adjusting the standard luminance curve.
It should be noted that, in the first type of adjustment parameter sequence, except for the first digital element, all the other digital elements are 0. For example, a first type of adjustment parameter sequence may be A1 (greater than 0), 0. Further, A1 may be set to a positive number less than 1 for the purpose of turning down the standard luminance curve (corresponding screen luminance is darker), or A1 may be set to a positive number greater than 1 for the purpose of turning up the standard luminance curve (corresponding screen luminance is lighter). In addition, the second class of adjustment parameter sequences includes at least one non-zero digital element in addition to the first digital element being other than 0.
(2) And constructing the target brightness curve based on the corrected first mapping relation and a second mapping relation 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, adjusting the backlight brightness of the electronic equipment based on the target brightness curve.
The specific implementation process of the step can comprise the following steps; detecting the ambient light brightness, determining a target backlight grade corresponding to the ambient light brightness based on the ambient light brightness and a target brightness curve, and further adjusting the backlight brightness based on the target backlight grade.
According to the method provided by the embodiment, the plurality of brightness modes are provided for the user to select, and then the standard brightness curve is corrected based on the target adjustment parameter sequence corresponding to the target brightness mode selected by the user, so that the target brightness curve is obtained, and backlight adjustment is performed based on the target brightness curve. Therefore, the target brightness curve is the brightness curve obtained by correcting the standard brightness curve based on the target adjustment parameters corresponding to the target brightness mode selected by the user, so that multiple brightness curves can be provided for the user by providing multiple brightness modes, the user can select a proper brightness curve according to the self needs, the human eye watching requirements of different users can be met, the adjusting precision is improved, and the watching experience of the user is improved.
Fig. 3 is a flowchart of yet another backlight adjustment method according to an exemplary embodiment of the present disclosure. This embodiment relates to a specific implementation procedure of how to configure the luminance pattern. Referring to fig. 3, the method provided in this embodiment, the configuration process of the luminance mode includes:
S301, responding to brightness mode configuration operation of a user, and outputting a configuration interface to the user; wherein the configuration interface includes a configuration specification for guiding a configuration process.
Specifically, a brightness mode configuration control may be provided on the brightness setting page such that a user triggers a brightness mode configuration operation based on the brightness mode configuration control.
The configuration is an explanatory file for guiding the configuration process, and the specific content thereof is not limited in this embodiment. For example, in one 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) digital elements, so as to correct the standard brightness curve through the digital element sequence formed by the input digital elements. If you want to turn up the standard brightness curve, we can input T (less than N above) numbers greater than 1 to make up the digital element sequence, if you want to turn down the standard brightness curve, we can input T numbers less than 1 to make up the digital element sequence.
S302, responding to a digital element sequence input by a user through the configuration interface, and storing the digital element sequence as an adjustment parameter sequence corresponding to a brightness mode.
For example, in one embodiment, the sequence of digital elements entered by the user is 2, 0. At this time, the digital element sequence may be stored as an adjustment parameter sequence corresponding to a luminance pattern.
It should be noted that, in a specific implementation, a luminance pattern may be generated at the luminance pattern selection interface, and the identifier of the luminance pattern and the digital element sequence are stored in association, so that the digital element sequence is used as an adjustment parameter sequence corresponding to the luminance pattern corresponding to the identifier to be stored.
The method provided by the embodiment provides a method for configuring the brightness mode, by which different brightness modes can be configured according to user requirements, the user requirements can be met, and the user experience is improved.
Fig. 4 is a flowchart of yet another backlight adjustment method according to an exemplary embodiment of the present disclosure. This embodiment relates to a specific implementation procedure of how to configure the luminance pattern. Referring to fig. 4, the method provided in this embodiment, the configuration process of the luminance mode includes:
s401, responding to a brightness mode configuration operation, and outputting a configuration interface to a user; wherein the configuration interface includes a plurality of candidate luminance patterns; the lengths of the candidate adjustment parameter sequences corresponding to different candidate brightness modes are different.
With reference to the foregoing, a brightness mode configuration control may be provided on the brightness setting page to enable a user to trigger a brightness mode configuration operation based on the brightness mode configuration control.
Further, the candidate luminance pattern is preconfigured in the electronic device at the time of shipment of the electronic device. When the electronic equipment leaves the factory, the length of the candidate adjustment parameter sequence corresponding to each candidate brightness mode and the value range of each digital element in the candidate adjustment parameters can be preconfigured, so that a user can configure the brightness mode meeting the self requirement based on the candidate brightness mode.
For example, in one embodiment, the configuration interface provides four candidate luminance patterns, which are respectively bright 1, bright 2, dark 1 and dark 2, and the lengths of the candidate adjustment parameter sequences corresponding to the four candidate luminance patterns are respectively 3, 4, 3 and 5.
S402, responding to the operation that a user selects a target candidate brightness mode through the configuration interface, and outputting the value range of each digital element in the candidate adjustment parameter sequence corresponding to the target candidate brightness mode to the user.
For example, in one embodiment, the target candidate brightness mode selected by the user is dark 1, and at this time, the value range of each digital element in the candidate adjustment sequence corresponding to the candidate brightness mode is displayed to the user. For example, in this example, the length of the candidate adjustment parameter sequence corresponding to the candidate brightness mode "dark 1" is 3, and the value range of each digital element in the candidate adjustment parameter sequence is: the first digital element is greater than 1, the second digital element is greater than 0 and less than 1, and the third digital element is 0.
S403, responding to the operation of selecting the target value from the value range by the user, and storing the digital element sequence formed by the target value selected by the user as an adjustment parameter sequence corresponding to a brightness mode.
In combination with the above example, for example, the user determines that the first digital element is 2, the second digital element is 0.5, and the third digital element is 0, and at this time, the following digital element sequences "2, 0.5, and 0" are saved as adjustment parameter sequences corresponding to one brightness mode.
In the foregoing description, when the method is specifically implemented, a luminance pattern may be generated in the luminance pattern selection interface, and the identifier of the luminance pattern and the digital element sequence are stored in association, so that the digital element sequence is stored as an adjustment parameter sequence corresponding to the luminance pattern corresponding to the identifier.
For example, in the example shown above, a luminance pattern identified as "custom 3" may be generated at the luminance pattern selection interface, and the identification of the luminance pattern may be stored in association with the following digital element sequences "2, 0.5, 0" to store the digital element sequences as the adjustment parameter sequences corresponding to the luminance pattern.
The method provided by the embodiment provides a method for configuring the brightness mode, by which different brightness modes can be configured according to user requirements, the user requirements can be met, and the user experience is improved.
