Detailed ways

The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Fig. 1 is a flow chart of a screen brightness adjustment method provided by an embodiment of the present application, the method can be executed by a screen brightness adjustment device, wherein the device can be implemented by software and/or hardware, and can generally be integrated into a smart terminal middle. As shown in Figure 1, the method includes:

Step 110, adjust the screen brightness of the smart terminal to the first brightness value according to the ambient light intensity.

It should be noted that the screen brightness adjustment modes of smart terminals, including but not limited to smartphones, tablet computers, e-books or handheld game consoles, generally include: automatic adjustment mode and manual adjustment mode. Among them, the automatic adjustment mode collects the ambient light intensity of the surrounding environment through the built-in light sensor of the smart terminal, and automatically adjusts the brightness value of the terminal screen (which can be a touch display screen or a display screen) according to the ambient light intensity. In the manual adjustment mode, by detecting the setting operation of the screen brightness input by the user, including the sliding operation on the touch screen, or the numerical input operation, etc., the brightness value of the terminal screen is adjusted according to the brightness value corresponding to the setting operation. For example, the state of the brightness adjustment bar is detected, and if a sliding action of the brightness adjustment bar is detected, the brightness value corresponding to the brightness adjustment bar is determined when the sliding action ends, and the brightness value of the terminal screen is updated according to the brightness value.

It should be noted that the smart terminal usually adopts an automatic adjustment mode to adaptively adjust the brightness of the screen. However, after detecting the setting operation of the screen brightness input by the user, the smart terminal adjusts the screen brightness of the smart terminal in response to the setting operation, and the adjusted screen brightness will remain at the brightness value corresponding to the setting operation, and Does not adaptively adjust due to its mismatch with the current environment's ambient light intensity. It can be understood that the screen brightness adjustment mode is switched from the automatic adjustment mode to the manual adjustment mode. That is, the CPU obtains the ambient light intensity from the light sensor according to the set cycle, but does not automatically adjust the screen brightness according to the ambient light intensity. In order to reduce the power consumption of the terminal in this scenario, the period for the CPU to obtain the ambient light intensity by the light sensor may be extended.

It should be noted that if the smart terminal detects a preset event that triggers the start of the automatic adjustment mode, it will control the screen adjustment mode to switch to the automatic adjustment mode. In this mode, the smart terminal can adjust the screen brightness according to the ambient light intensity.

The light sensor acquires the ambient light intensity of the surrounding environment according to the set period, and determines the target brightness level of the terminal screen matching the current environment according to the ambient light intensity value. Get the first brightness value of the current terminal screen. If the first brightness value does not match the target brightness level, the current first brightness value is updated according to the brightness value corresponding to the target brightness level. If the first brightness value matches the target brightness level, the brightness value of the current screen remains unchanged.

It should be noted that the set period may be the default period of the system, or may be set by the user according to actual conditions. Among them, the experimental smart terminal can be distributed to a preset number of user groups, and the automatic adjustment mode of the screen brightness has been disabled in advance for the smart terminal, so as to collect the screen brightness adjustment behavior of the user group, and analyze the user's behavior according to the screen brightness adjustment behavior. Usually, how long does it take to manually adjust the screen brightness after the screen brightness does not match the current ambient light intensity, so that the setting period is determined according to the analysis result.

It should be noted that the adjustable range of screen brightness can be from 0 to 255, and the adjustment range can be divided into a preset number of brightness levels according to the user's usage habits. For example, the adjustment range can be divided into five brightness levels: 30, 70, 150, 220, 255. Wherein, the higher the brightness level is, the brighter the screen is. The correlation between the brightness level of the smart terminal and the ambient light intensity is set in advance. For example, suppose the brightness level is 30 (the brightness of the screen does not exceed 30), and the range of ambient light intensity matching this level is set to 10~30lux; assuming the brightness level is 70 (the brightness of the screen does not exceed 70), the setting matches this level The range of ambient light intensity is 31~61lux and so on.

Step 120 , when detecting a setting operation of screen brightness input by a user, acquire a second brightness value corresponding to the setting operation.

It should be noted that the setting operation may be a sliding operation on the brightness adjustment bar, or an input operation of a brightness value, including but not limited to a voice input operation and a manual input operation.

Exemplarily, when it is detected that the screen brightness adjustment interface is called, the execution subject that calls the screen brightness adjustment interface is determined. If the execution subject is a touch screen, it is determined that a setting operation for screen brightness input by a user is detected. For example, if the brightness of the screen is adjusted through the brightness adjustment bar, the position at which the setting operation stops is recorded. According to the corresponding relationship between the position and the brightness value, the brightness value corresponding to the position of the brightness adjustment bar is determined as the second brightness value.

Optionally, if the execution subject is a microphone, it is determined that a user-input setting operation for screen brightness is detected. If the brightness of the screen is set by voice, the brightness value input by the user by voice may be obtained, and the brightness value may be used as the second brightness value.

Step 130: Compare the second brightness value with the first brightness value, and determine whether to enable a preset time window mechanism according to the comparison result.

It should be noted that the time window mechanism includes: updating the screen brightness according to the second brightness value, and prompting the user to adjust the screen brightness if the time for which the screen brightness maintains the second brightness exceeds a preset time threshold.

Exemplarily, the magnitudes of the second brightness value and the first brightness value are compared. If the ambient light intensity is lower than the preset light intensity threshold, that is, the current environment is a dark environment, and the second brightness value is greater than the first brightness value, the control screen brightness adjustment mode is switched from automatic adjustment mode to manual adjustment mode; in addition, trigger The activation event of the time window mechanism determines that the smart terminal is in an abnormal state of brightness. It should be noted that if the ambient light intensity is lower than the preset light intensity threshold, that is, the current environment is a dark environment, and the second brightness value is greater than the first brightness value, the preset time window mechanism is enabled, and when the enabled event is When triggered, perform an action that enables the preset time window mechanism.

It should be noted that if the current environment is a dark environment and the second brightness value is lower than the first brightness value, the preset time window mechanism is not enabled, and it is determined that the smart terminal is in a normal brightness state.

Alternatively, assuming that the current environment is a dark environment, the absolute value of the difference between the second brightness value and the first brightness value is calculated, and the absolute value is compared with a preset data threshold. If the absolute value exceeds the preset data threshold, the control screen brightness adjustment mode is switched from automatic adjustment mode to manual adjustment mode; in addition, an activation event of the time window mechanism is also triggered to determine that the smart terminal is in an abnormal brightness state. In order to avoid causing greater damage to the user's eyesight, the preset data threshold can be set relatively small, that is, the user can be allowed to slightly adjust the screen brightness, so that the screen brightness and the first brightness value have a small deviation. At this time, Since the second brightness value adjusted by the user is close to the first brightness value, the user's eyesight will not be greatly damaged, and the enabling event of the preset time window mechanism may not be triggered.

Exemplarily, if the ambient light intensity is higher than the preset light intensity threshold, that is, the current environment is a bright environment, and the second brightness value is smaller than the first brightness value, the control screen brightness adjustment mode is switched from the automatic adjustment mode to the manual adjustment mode; In addition, an enabling event of the time window mechanism is also triggered to determine that the smart terminal is in an abnormal state of brightness. It should be noted that if the ambient light intensity is higher than the preset light intensity threshold, that is, the current environment is a bright environment, and the second brightness value is smaller than the first brightness value, the preset time window mechanism is enabled, and when the enabled event is When triggered, perform an action that enables the preset time window mechanism.

Alternatively, assuming that the current environment is a bright environment, the absolute value of the difference between the second brightness value and the first brightness value is calculated, and the absolute value is compared with a preset data threshold. If the absolute value exceeds the preset data threshold, the control screen brightness adjustment mode is switched from automatic adjustment mode to manual adjustment mode; in addition, an activation event of the time window mechanism is also triggered to determine that the smart terminal is in an abnormal brightness state.

Step 140, if the time window mechanism is enabled, execute an adjustment policy corresponding to the time window mechanism.

It should be noted that the adjustment strategy includes: when the duration of the abnormal brightness state is greater than or equal to a preset threshold, output a prompt message for adjusting the current screen brightness; when the duration of the abnormal brightness state is less than the preset threshold , to disable the time window mechanism.

Wherein, the preset threshold may be a default value of the system, and may also be adjusted according to the usage habits of the user. For example, the user's historical operation data on the prompt information within a set period of time (for example, one month) is collected. The data analysis method is used to classify the historical operation data, extract features, etc., and determine what the user's input operation for the prompt information is usually. If the user's input operation for the prompt information is usually a positive indication, that is, to adjust the brightness of the screen, the system default value remains unchanged. If the user's input operation for the prompt information is usually a negative instruction, that is, to give up adjusting the screen brightness, then increase the preset threshold. For example, assuming that the original preset threshold is 30 minutes, the preset threshold can be adjusted to 1 hour.

Exemplarily, if an activation event of the time window mechanism is detected, the time window mechanism is enabled, that is, the duration of the smart terminal being in the abnormal brightness state is recorded. Wherein, the abnormal brightness state includes: if the current environment is a dark environment, and the second brightness value is greater than the first brightness value, then determine that the smart terminal is in an abnormal brightness state; or, assuming that the current environment is a dark environment, calculate the second brightness value and The absolute value of the difference of the first brightness value, if the absolute value exceeds the preset data threshold, it is determined that the smart terminal is in an abnormal brightness state; or, if the current environment is a bright environment, and the second brightness value is less than the first brightness value , it is determined that the smart terminal is in an abnormal brightness state; or, assuming that the current environment is a bright environment, calculate the absolute value of the difference between the second brightness value and the first brightness value, and if the absolute value exceeds the preset data threshold, then determine the The smart terminal is in an abnormal state of brightness.

It should be noted that the duration is the time during which the abnormal brightness state continuously exists.

When the duration is greater than or equal to the preset threshold, a prompt message for adjusting the current screen brightness is output. For example, if the current environment is a dark environment, record the duration for which the second brightness value is greater than the first brightness value, and if it is detected that the user adjusts the screen brightness to the first brightness value or lower than the first the third brightness value of the brightness value, stop timing. The duration time during which the second brightness value is greater than the first brightness value is acquired, and the duration time is compared with a preset threshold. If the duration of the second brightness value greater than the first brightness value is greater than the preset threshold, output "Your current screen is bright, it is recommended to restore to the default brightness". Wherein, the default brightness is the screen brightness corresponding to the current ambient light intensity, that is, it can be regarded as the first brightness value.

When the duration is less than a preset threshold, the time window mechanism is disabled. For example, if the current environment is a dark environment, and the duration of the second brightness value greater than the first brightness value is less than the preset threshold, the time window mechanism is disabled, that is, the time window mechanism disappears, and the duration is set to zero, so that the next time When an abnormal state of brightness in which the second brightness value is greater than the first brightness value occurs, the duration of the state is accurately recorded.

In the technical solution of this embodiment, the screen brightness of the smart terminal is adjusted to the first brightness value according to the ambient light intensity; when the setting operation for the screen brightness input by the user is detected, the second brightness value corresponding to the setting operation is obtained; comparison The second brightness value and the first brightness value determine whether to enable the preset time window mechanism according to the comparison result, and execute the adjustment strategy corresponding to the time window mechanism. After the situation that the screen brightness does not match the current ambient light intensity occurs, through this The adjustment strategy adjusts the brightness of the screen to avoid the situation that the adjustment operation of the screen brightness is not intelligent enough, thereby solving the problem that the user is prone to fatigue when staring at the screen that is not suitable for the current ambient light intensity for a long time.

FIG. 2 is a flow chart of another method for adjusting screen brightness provided by an embodiment of the present application. As shown in Figure 2, the method includes:

Step 201. Adjust the screen brightness of the smart terminal to a first brightness value according to the ambient light intensity.

Step 202 , when detecting a setting operation of screen brightness input by a user, acquire a second brightness value corresponding to the setting operation.

Step 203 , compare the second brightness value with the first brightness value, determine whether to enable the preset time window mechanism according to the comparison result, if yes, execute step 204 , otherwise, execute step 212 .

Step 204 , judging whether the difference between the current ambient light intensity value and the previous adjacent ambient light intensity value is smaller than the set light intensity threshold, if yes, execute step 205 , otherwise, execute step 212 .

Exemplarily, after the time window mechanism is enabled, it is detected whether the ambient light intensity of the surrounding environment changes greatly, if yes, no significant change occurs, and step 205 is performed. On the contrary, if a large change occurs, the time window mechanism may no longer be applicable, and step 212 is executed accordingly.

It should be noted that this step is not a mandatory step, and in some examples, this step may not be performed, and step 205 may be directly performed.

Step 205. Record the duration of the smart terminal being in the abnormal brightness state.

If the ambient light intensity of the current environment is lower than the preset light intensity threshold, it is a dark environment, then when the second brightness value is greater than the first brightness value, start the timer, and when it is detected that the second brightness value is lower than the first brightness value When the brightness value is reached, the timer is stopped, and the value of the timer is read as the duration of the abnormal brightness state.

Alternatively, if the ambient light intensity of the current environment is higher than the preset light intensity threshold, which is a bright environment, then when the second brightness value is less than the first brightness value, start the timer, and when the second brightness is detected When the value is greater than the first brightness value, stop timing, and read the value of the timer as the duration of the abnormal brightness state.

Alternatively, the absolute value of the difference between the second brightness value and the first brightness value is calculated. When the absolute value is greater than the preset data threshold, the timer is started, and when the absolute value is smaller than the preset data threshold, the timer is stopped, and the value of the timer is read as the duration of the abnormal brightness state.

Step 206 , judging whether the duration is not less than a preset threshold, if yes, execute step 207 , otherwise, execute step 212 .

Wherein, the preset threshold value may be a default value of the system, and may also be adjusted according to the user's usage habits. The application environment of the smart terminal may also be determined according to the ambient light intensity of the current environment, and the threshold corresponding to the application environment of the smart terminal may be obtained. preset threshold. For example, the corresponding relationship between scenes and preset thresholds can be set in advance, that is to say, scenes without lights at night, scenes with lights on at night, indoor scenes during the day, and outdoor scenes during the day can be distinguished, and different preset thresholds can be set for different scenes.

The relationship between the duration and the preset threshold is compared. If the duration is not less than the preset threshold, step 207 is executed.

Step 207 , outputting prompt information for adjusting the current screen brightness.

When the duration is greater than or equal to the preset threshold, a prompt message for adjusting the current screen brightness is output. For example, when the duration is greater than the preset threshold, a pop-up window reminds the user "Your current screen is bright, it is recommended to restore to the default brightness".

Step 208, acquiring a user operation instruction.

Wherein, the user operation instruction includes an affirmative instruction and a negative instruction, the affirmative instruction is used to indicate that the smart terminal is allowed to automatically adjust the screen brightness in response to the prompt information, and the negative instruction is used to indicate that the smart terminal is not allowed to respond to the prompt information to perform screen brightness adjustment. auto-adjust.

Step 209 , judging whether the user operation instruction is an affirmative instruction, if yes, execute step 210 , otherwise execute step 211 .

It is determined whether the user operation instruction is to adjust screen brightness, and if yes, step 210 is performed.

Step 210, adjust the screen brightness to the first brightness value, and control the screen brightness adjustment mode to switch from the manual adjustment mode to the automatic adjustment mode.

If the user operation instruction is to adjust screen brightness, the first brightness value is obtained, and the screen brightness is updated accordingly. In addition, the control screen brightness adjustment mode is switched from the manual adjustment mode to the automatic adjustment mode, so as to verify whether the current screen brightness is compatible with the current ambient light intensity according to the ambient light intensity collected by the light sensor. If it is detected that the screen brightness does not match the current ambient light intensity, the screen brightness is automatically updated according to the brightness level matched by the current ambient light intensity.

Step 211. Keep the value of the screen brightness unchanged.

If the user operation instruction is to give up adjusting the screen brightness, then keep the screen brightness unchanged at the second brightness value. In addition, the screen brightness adjustment mode can also be maintained as the manual adjustment mode.

Step 212, disable the time window mechanism.

When the duration is less than the preset threshold, the control time window mechanism disappears, that is, the time window mechanism is disabled. Optionally, after the time window mechanism is disabled, if the current screen brightness adjustment mode is the manual mode, the screen brightness adjustment mode can also be automatically switched to the automatic adjustment mode.

In the technical solution of this embodiment, after the time window mechanism is enabled, it is additionally detected whether the ambient light intensity of the surrounding environment has changed greatly, and it is determined whether the time window mechanism is still applicable according to the detection result, thereby avoiding the occurrence of an inappropriate time window mechanism. Misadjustment of screen brightness where applicable improves adjustment accuracy. In addition, after outputting the prompt information for adjusting the current screen brightness, the operation of obtaining the user operation instruction is added, so that the screen brightness is adjusted accordingly according to the user operation instruction, and when the screen brightness is different from the current ambient light intensity, After matching the situation, the screen brightness is adjusted intelligently to avoid the situation that the adjustment operation of the screen brightness is not intelligent enough, thereby solving the problem that the user is prone to fatigue when staring at the screen that is not suitable for the current ambient light intensity for a long time.

FIG. 3 is another screen brightness adjustment method provided by the embodiment of the present application. As shown in Figure 3, the method includes:

Step 301. Adjust the screen brightness of the smart terminal to a first brightness value according to the ambient light intensity.

Step 302 , when a setting operation input by a user for screen brightness is detected, acquire a second brightness value corresponding to the setting operation.

Step 303 , compare the second brightness value with the first brightness value, determine whether to enable the preset time window mechanism according to the comparison result, if yes, execute step 304 , otherwise, execute step 318 .

Step 304 , judging whether the difference between the current ambient light intensity value and the previous adjacent ambient light intensity value is smaller than the set light intensity threshold, if yes, execute step 305 , otherwise, execute step 318 .

Step 305 , the light sensor acquires the current ambient light intensity, compares the ambient light intensity with a preset light intensity threshold, and determines the timing of starting the timer according to the comparison result.

Exemplarily, the current ambient light intensity is acquired by a light sensor. If the ambient light intensity is lower than the preset light intensity threshold, a timer may be started when the second brightness value is greater than the first brightness value; if the ambient light intensity is higher than the preset light intensity threshold, Then a timer may be started when the second brightness value is smaller than the first brightness value.

Step 306, timing by a timer.

Step 307. After the timer is started, a setting operation for screen brightness input by the user is detected, and a third brightness value corresponding to the setting operation is acquired.

After the timer is started, that is, during the timing period, if it is detected that the user has input another setting operation for screen brightness, the brightness value corresponding to the position of the brightness adjustment bar may be used as the third brightness value when the setting operation ends. Optionally, the brightness value input by the user and so on can also be obtained.

Step 308: Determine whether the surrounding environment is a dark environment or a bright environment according to the relationship between the ambient light intensity and the preset light intensity threshold.

It should be noted that the ambient light intensity may be acquired by a light sensor.

The ambient light intensity is compared with a preset light intensity threshold to determine whether the current environment is a dark environment or a bright environment.

It should be noted that this step is not required to be performed, and step 309 may also be performed directly.

Step 309 , if the ambient light intensity is lower than the preset light intensity threshold, judge whether the third brightness value is smaller than the first brightness value, if yes, execute step 310 , otherwise, execute step 306 .

It should be noted that if the ambient light intensity is higher than the preset light intensity threshold, this step may be replaced by judging whether the third brightness value is greater than the first brightness value.

Or, regardless of whether the ambient light intensity is lower or higher than the preset light intensity, this step can be replaced by calculating the difference between the third brightness and the first brightness value, and comparing the absolute value of the difference with the preset data threshold . If the absolute value of the difference is smaller than the preset data threshold, step 310 is executed.

Step 310, stop the timer.

It should be noted that there are many ways of timing, and are not limited to the way of using a timer listed in this embodiment. For example, it is also possible to read the system time once when the condition for timing start is satisfied, and read the system time again when the condition for timing termination is satisfied, and determine the duration according to the time difference between the two readings of the system time.

Step 311, read the value of the timer as the duration of the abnormal brightness state.

Step 312 , judging whether the duration is not less than a preset threshold, if yes, execute step 313 , otherwise, execute step 318 .

Step 313 , outputting prompt information for adjusting the current screen brightness.

Step 314, acquire user operation instructions.

Step 315 , judging whether the user operation instruction is an affirmative instruction, if yes, execute step 316 , otherwise execute step 317 .

Step 316 , adjust the screen brightness to the first brightness value, and control the screen brightness adjustment mode to switch from the manual adjustment mode to the automatic adjustment mode.

Step 317 , keeping the value of the brightness of the screen unchanged.

Step 318, disable the time window mechanism.

In the technical solution of this embodiment, after the user manually adjusts the screen brightness, if the screen brightness adjustment operation is input again, the third brightness value corresponding to the screen brightness adjustment operation is obtained, and the third brightness value is compared with the first brightness value , if the third brightness value is higher than the first brightness value, continue timing, if the third brightness value is lower than the first brightness value, then stop timing, that is to say, during timing, no matter how many times the user manually adjusts the screen Brightness, as long as the adjusted screen brightness value is greater than the first brightness value, continue timing, and get the duration of abnormal screen brightness according to the timing value; and when the duration meets the adjustment conditions, remind the user to restore the screen brightness to the default setting, Avoid situations where users stare at a screen that is not suitable for the current ambient light intensity for a long time and are prone to fatigue.
