Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The embodiment of the application provides a screen brightness control method, which can be applied to electronic equipment with a display screen, wherein the electronic equipment can be a mobile phone, a tablet computer, wearable electronic equipment and the like. The electronic device can control the screen brightness of the display screen according to the received screen brightness control instruction, and the screen brightness control can be increasing the screen brightness or decreasing the screen brightness.
As shown in fig. 1, a specific processing procedure of the screen brightness control method provided in the embodiment of the present application includes:
In implementation, the electronic device may receive a screen brightness control instruction when a preset operation performed by a user is detected. The preset operation may be clicking a certain preset icon to enter or leave a certain page, or clicking a certain preset icon to display the two-dimensional code.
In the embodiment of the present application, the screen brightness control instruction may be a screen brightness increase instruction or a screen brightness decrease instruction. According to different preset operations executed by a user, the screen brightness control instruction received by the electronic equipment is different.
For example, the preset operation may be a two-dimensional code display operation, and when the electronic device detects the two-dimensional code display operation performed by the user, the screen brightness control instruction received by the electronic device may be a screen brightness increase instruction. The preset operation may be clicking an icon exiting the payment completion interface, and when the electronic device detects that the user clicks the icon exiting the payment completion interface, the screen brightness control instruction received by the electronic device may be a screen brightness reduction instruction.
The electronic device may determine the target screen brightness in various ways, and if the screen brightness control instruction is the screen brightness increase instruction, the electronic device may use the maximum screen brightness as the target screen brightness, or the electronic device may randomly select a screen brightness from a pre-stored high screen brightness range as the target screen brightness.
If the screen brightness control instruction is a screen brightness reduction instruction, the electronic equipment can randomly select a screen brightness from a pre-stored range of screen brightness suitable for human eyes as a target screen brightness. Or, for the case that the electronic device receives the screen brightness increasing instruction first, adjusts the screen brightness to the target screen brightness, and then receives the screen brightness decreasing instruction, the electronic device may use the screen brightness of the display screen before receiving the screen brightness increasing instruction as the target screen brightness corresponding to the screen brightness decreasing instruction.
And 102, regulating the screen brightness of the display screen for multiple times according to the first screen brightness of the display screen before regulating the screen brightness and the screen brightness gradient rule until the second screen brightness of the display screen reaches the target screen brightness after regulating the screen brightness.
The electronic equipment can be preset with a screen brightness gradient rule, wherein the screen brightness gradient rule can be that the second screen brightness determined this time is closer to the target screen brightness than the second screen brightness determined last time; the screen brightness gradient rule can also be that the screen brightness changes at a constant speed; the screen brightness gradient rule can also be that the screen brightness changes slowly first, rapidly in the middle and slowly afterwards.
In implementation, the electronic device may determine a first screen brightness of the display screen before adjusting the screen brightness, and then, the electronic device may determine the screen brightness according to the first screen brightness and the screen brightness gradient rule in a process of adjusting the screen brightness each time, so as to obtain a second screen brightness of the display screen after adjusting the screen brightness. The electronic device may set the screen brightness of the display screen to the second screen brightness.
And the electronic equipment can judge whether the second screen brightness reaches the target screen brightness, and if the second screen brightness does not reach the target screen brightness, the electronic equipment can repeat the step of calculating the screen brightness according to the first screen brightness and the change speed of the screen brightness in the screen brightness gradient rule to obtain the second screen brightness of the display screen after the screen brightness is adjusted. If the second screen brightness reaches the target screen brightness, the electronic device may not perform subsequent processing.
In this embodiment of the application, the first screen brightness may be a current screen brightness of the display screen when the electronic device receives the screen brightness control instruction. The first screen brightness may also be the current screen brightness of the display screen before the screen brightness is adjusted each time, and it can be understood that the first screen brightness in the process of adjusting the screen brightness this time is the second screen brightness in the process of adjusting the screen brightness last time.
Optionally, when the screen brightness gradient rule is related to the change speed of the screen brightness, the electronic device determines a specific implementation manner of the second screen brightness according to the first screen brightness and the screen brightness gradient rule, and the following description is respectively given for two value conditions of the first screen brightness:
in the first case, the first screen brightness is the current screen brightness of the display screen when the electronic device receives the screen brightness control instruction.
The electronic equipment can calculate the screen brightness according to the change speed of the screen brightness, the first screen brightness and the adjustment times of the screen brightness in the screen brightness gradient rule in the process of adjusting the screen brightness each time to obtain the second screen brightness of the display screen after the screen brightness is adjusted.
For example, the screen brightness gradient rule is that the screen brightness changes at a constant speed, and in the process of adjusting the screen brightness for the second time, the electronic device may calculate the screen brightness according to the adjustment frequency 2, the change speed of the screen brightness of 0.1/time, and the first screen brightness of 0.6, to obtain the second screen brightness of 0.8 of the display screen after the screen brightness is adjusted.
And in the second case, the first screen brightness is the current screen brightness of the display screen before the screen brightness is adjusted each time.
If the screen brightness gradient rule is that the screen brightness changes at a constant speed, the electronic device may calculate the screen brightness according to the change speed of the first screen brightness and the screen brightness, and obtain a second screen brightness of the display screen after the screen brightness is adjusted.
For example, the electronic device may calculate the screen brightness according to the first screen brightness of 0.6 and the change speed of the screen brightness of 0.1/time, and obtain a second screen brightness of 0.7 of the display screen after the screen brightness is adjusted.
If the screen brightness gradient rule is a screen brightness variable speed change, the electronic device may pre-store a corresponding relationship between a screen brightness interval and a change speed, where the corresponding relationship between the screen brightness interval and the change speed may be: the change speed corresponding to the screen brightness interval [0.3, 0,5] is 0.05/time, the change speed corresponding to the screen brightness interval [0.5, 0.8] is 0.1/time, and the change speed corresponding to the screen brightness interval [0.8, 1] is 0.05/time.
After determining the first screen brightness, the electronic device may determine a screen brightness interval to which the first screen brightness belongs and a change speed corresponding to the screen brightness interval. Then, the electronic device can calculate the screen brightness according to the first screen brightness and the determined change speed of the screen brightness to obtain a second screen brightness of the display screen after the screen brightness is adjusted.
For example, after determining the first screen brightness 0.9, the electronic device may determine a screen brightness interval [0.8, 1] to which the first screen brightness belongs, and a change speed corresponding to the screen brightness interval is 0.05/time. Then, the electronic device may calculate the screen brightness according to the first screen brightness 0.9 and the determined change speed of the screen brightness of 0.05/time, so as to obtain a second screen brightness of 0.95 of the display screen after the screen brightness is adjusted.
In the embodiment of the application, the electronic device may determine the target screen brightness when receiving the screen brightness control instruction, and then adjust the screen brightness of the display screen for multiple times according to the first screen brightness of the display screen before adjusting the screen brightness and the screen brightness gradient rule until the second screen brightness of the display screen after adjusting the screen brightness reaches the target screen brightness. Because the screen brightness of the display screen is adjusted for multiple times according to the first screen brightness of the display screen before the screen brightness is adjusted and the screen brightness gradual change rule, the situation of screen brightness sudden change can be avoided, the adjustment process of adapting to the screen brightness by eyes of a user is facilitated, and therefore the user experience can be improved.
Alternatively, the electronic device may be preset with an adjustment frequency, such as 50Hz or 60 Hz. The electronic device may control the screen brightness according to the first screen brightness of the display screen before adjusting the frequency and adjusting the screen brightness and the screen brightness gradient rule, as shown in fig. 2, the specific control process includes:
And the second screen brightness is closer to the target screen brightness than the second screen brightness determined last time.
In an implementation, the electronic device may determine a first screen brightness of the display screen before adjusting the screen brightness according to the adjustment frequency. Then, the electronic device may determine the screen brightness between the first screen brightness and the target screen brightness to obtain a second screen brightness of the display screen after the screen brightness is adjusted.
The electronic device may determine the screen brightness between the first screen brightness and the target screen brightness in various ways, and in a possible implementation, the electronic device may randomly select a screen brightness between the first screen brightness and the target screen brightness.
When the first screen brightness is the current screen brightness of the display screen when the electronic device receives the screen brightness control instruction, the electronic device may randomly select a screen brightness larger than the current screen brightness between the first screen brightness and the target screen brightness according to the adjustment frequency as the second screen brightness of the display screen after the screen brightness is adjusted. The current screen brightness is the second screen brightness determined in the last screen brightness adjustment, so that the second screen brightness determined this time is closer to the target screen brightness than the second screen brightness determined last time.
For example, the adjustment frequency is 50Hz, the first screen brightness of the display screen before the screen brightness is adjusted is 0.6, the target screen brightness is 1, and the electronic device may randomly select a screen brightness 0.75 larger than the current screen brightness 0.7 as the second screen brightness of the display screen after the screen brightness is adjusted between the first screen brightness 0.6 and the target screen brightness 1 every 20ms according to the adjustment frequency.
When the first screen brightness is the current screen brightness of the display screen before the screen brightness is adjusted each time, the electronic device may randomly select a screen brightness between the first screen brightness and the target screen brightness as the second screen brightness of the display screen after the screen brightness is adjusted.
In another possible implementation manner, the electronic device may calculate the screen brightness according to the change speed of the screen brightness and the first screen brightness, and the specific processing process may refer to the processing process in step 102, which is not described herein again.
In implementation, if the second screen brightness does not reach the target screen brightness, the electronic device may repeatedly perform the step of determining the screen brightness between the first screen brightness of the display screen before the screen brightness is adjusted and the target screen brightness according to the adjustment frequency to obtain the second screen brightness of the display screen after the screen brightness is adjusted, that is, return to the step 201. If the second screen brightness reaches the target screen brightness, the electronic device can perform step 204.
In the present embodiment, the processing sequence of step 202 and step 203 in the actual processing process is not specifically limited.
And step 204, no subsequent processing is carried out.
In the embodiment of the application, the electronic device may determine the screen brightness between the first screen brightness of the display screen before the screen brightness is adjusted and the target screen brightness according to the adjustment frequency, and obtain the second screen brightness of the display screen after the screen brightness is adjusted. Then, the electronic device may determine whether the second screen brightness reaches the target screen brightness. If the second screen brightness does not reach the target screen brightness, the electronic device may repeat the determining the second screen brightness step; if the second screen brightness reaches the target screen brightness, the electronic device may not perform subsequent processing.
Because electronic equipment confirms the in-process of second screen brightness according to the regulation frequency, this second screen brightness who determines compares with the second screen brightness who determines last time and is more close target screen brightness, consequently, set up screen brightness according to the second screen brightness who determines in proper order, can realize the gradual change control of screen brightness to can avoid appearing the condition of screen brightness sudden change, the accommodation process of user's eyes adaptation screen brightness of being convenient for improves user experience.
Optionally, a screen brightness calculation formula may be stored in the electronic device in advance, and the electronic device may calculate, according to the adjustment frequency and the screen brightness calculation formula, a second screen brightness of the display screen after the screen brightness is adjusted, as shown in fig. 3, the specific processing procedure includes:
In implementation, the electronic device may determine the number of times of adjustment when the screen brightness is adjusted this time. For example, the electronic device may determine that the number of adjustments is 1 when the screen brightness is adjusted for the first time. Subsequently, when the screen brightness is adjusted each time, the electronic device may add 1 to the locally stored adjustment times to obtain the adjustment times when the screen brightness is adjusted this time.
Then, the electronic device may calculate a ratio of the adjustment frequency of the screen brightness to a pre-stored adjustment frequency, to obtain the adjustment time when the screen brightness is adjusted this time.
For example, the number of times of adjustment may be represented as count, the frequency of adjustment may be represented as f, and the adjustment time t when the screen brightness is adjusted this time may be represented as t ═ count/f.
In implementation, the electronic device may calculate the second screen brightness of the display screen after the current screen brightness adjustment according to the first screen brightness of the display screen before the screen brightness adjustment, the target screen brightness, the adjustment time, and a pre-stored screen brightness calculation formula.
Optionally, in a case that a screen brightness increase instruction is received, an embodiment of the present application provides a screen brightness calculation formula, as shown in equation (1):
br＝B1+(B2-B1)*bi(t) (1)
wherein, B1Is the first screen brightness, B2Is the target screen brightness, brIs the brightness of the second screen, and is,
t is the adjustment time.
Fig. 4a is a schematic diagram of screen brightness changing with adjustment time according to an embodiment of the present application, where a horizontal axis represents adjustment time and a vertical axis represents screen brightness. When the adjusting time t reaches 1s, the screen brightness can be adjusted to the target screen brightness 1.
In the case of receiving the screen brightness reduction instruction, the embodiment of the present application further provides a screen brightness calculation formula, as shown in equation (2):
br＝B1+(B2-B1)*bd(t) (2)
wherein, bd(t)＝1-bi(t)。
Fig. 4b is a schematic diagram of another screen brightness variation with adjustment time provided in the embodiment of the present application, in which the horizontal axis represents adjustment time and the vertical axis represents screen brightness. When the adjusting time t reaches 1s, the screen brightness can be adjusted to the target screen brightness 0.
Because the electronic equipment adopts the screen brightness calculation formula to calculate the second screen brightness, the screen brightness gradual change effects of the screen brightness which changes slowly firstly, quickly in the middle and slowly afterwards can be realized, the adjustment process of adapting to the screen brightness by eyes of a user is facilitated, and the user experience is improved.

From this, electronic equipment sets up screen brightness according to the second screen brightness who determines in proper order, can realize the gradual change control of screen brightness to can avoid appearing the condition of screen brightness sudden change, the user eyes of being convenient for adapt to screen brightness's accommodation process, improvement user experience.
Furthermore, different screen brightness gradient effects can be realized by setting different screen brightness calculation formulas.
Optionally, the adjusting frequency is a screen refresh frequency.
In the embodiment of the present application, if the frequency set by the processor in the electronic device is selected as the adjustment frequency, the processor may be affected by the data processing load, and therefore, the frequency may be inaccurate. The screen refreshing frequency is not influenced by the data processing load of the processor, so that the periodicity of the screen brightness determination can be ensured by selecting the screen refreshing frequency as the adjusting frequency, and the accuracy of the screen brightness adjustment is ensured. Meanwhile, the screen brightness is changed according to the screen refreshing frequency, so that the eyes of a user can adapt to the adjusting process of the screen brightness conveniently, and the user experience is improved.
Optionally, the electronic device may store a control time period T required for performing the screen brightness control in advance, where T may be set by a developer according to experience, and for example, T may be 0.5 s.
