Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a method for adjusting screen brightness according to an embodiment of the present disclosure, where the method may be performed by a device for adjusting screen brightness, where the device may be implemented by software and/or hardware, and may be generally integrated in an intelligent terminal. As shown in fig. 1, the method includes:
and step 110, adjusting the screen brightness of the intelligent terminal to a first brightness value according to the ambient light intensity.
It should be noted that, the screen brightness adjustment mode of the smart terminal, including but not limited to a smart phone, a tablet computer, an electronic book or a handheld game device, generally includes: an automatic adjustment mode and a manual adjustment mode. In the automatic adjustment mode, the ambient light intensity of the surrounding environment is acquired through a light sensor arranged in the intelligent terminal, and the brightness value of a terminal screen (which can be a touch display screen or a display screen) is automatically adjusted according to the ambient light intensity. And in the manual adjustment mode, the brightness value of the terminal screen is adjusted according to the brightness value corresponding to the setting operation by detecting the setting operation aiming at the screen brightness input by the user, including sliding operation on the touch display screen, or numerical value input operation and the like. For example, the state of the brightness adjusting bar is detected, and if the sliding motion of the brightness adjusting bar is detected, the brightness value corresponding to the brightness adjusting bar is determined when the sliding motion is terminated, and the brightness value of the terminal screen is updated according to the brightness value.
It should be noted that, the intelligent terminal generally adopts an automatic adjustment mode to adaptively adjust the screen brightness. However, after detecting the setting operation for 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 is maintained at the brightness value corresponding to the setting operation and is not adaptively adjusted due to mismatch with the ambient light intensity of the current environment. It can be understood that the screen brightness adjustment mode is switched from the automatic adjustment mode to the manual adjustment mode. The CPU obtains the ambient light intensity by the light sensor according to the set period, 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 such a scenario, the period of the CPU acquiring the ambient light intensity by the light sensor may be extended.
It should be noted that, if the intelligent terminal detects a preset event triggering the start of the automatic adjustment mode, the screen adjustment mode is controlled to be switched to the automatic adjustment mode, and in this mode, the intelligent terminal can adjust the screen brightness according to the ambient light intensity.
And acquiring the ambient light intensity of the surrounding environment by the light sensor according to a set period, and determining the target brightness level of the terminal screen matched with the current environment according to the ambient light intensity value. And acquiring a first brightness value of the current terminal screen. And if the first brightness value is not matched with the target brightness level, updating the current first brightness value according to the brightness value corresponding to the target brightness level. If the first brightness value is matched with the target brightness level, the brightness value of the current screen is kept unchanged.
It should be noted that the set period may be a default period of the system, or may be set by the user according to actual conditions. The screen brightness adjusting behaviors of the user groups are collected by distributing the intelligent terminals for experiments to a preset number of user groups, the screen brightness adjusting behaviors of the user groups are analyzed according to the screen brightness adjusting behaviors, and the screen brightness of the user groups is adjusted manually for a long time after the screen brightness is not matched with 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 the screen brightness may be 0 to 255, and the adjustable range may be divided into a preset number of brightness levels according to the use habit of the user, for example, the adjustable range may be divided into 5 brightness levels: 30. 70, 150, 220, 255. Wherein the higher the brightness level, the greater the screen brightness. And presetting the incidence relation between the brightness level of the intelligent terminal and the ambient light intensity. For example, assuming that the brightness level is 30 (the screen brightness does not exceed 30), the ambient light intensity range matched with the level is set to be 10-30 lux; assuming that the brightness level is 70 (screen brightness is not more than 70), the ambient light intensity range matching the level is set to be 31-61 lux, etc.
And 120, when the setting operation aiming at the screen brightness input by the user is detected, acquiring a second brightness value corresponding to the setting operation.
The setting operation may be a sliding operation for the brightness adjustment bar, or may be a brightness value input operation including, but not limited to, a voice input operation and a manual input operation.
Illustratively, when detecting that the screen brightness adjusting interface is called, judging to call the execution subject of the screen brightness adjusting interface. And if the execution main body is a touch screen, determining that the setting operation aiming at the screen brightness input by the user is detected. For example, if the screen brightness is adjusted by the brightness adjustment bar, the position at which the setting operation is stopped is recorded. And determining the brightness value corresponding to the position of the brightness adjusting bar as a second brightness value according to the corresponding relation between the position and the brightness value.
Alternatively, if the execution subject is a microphone, it is determined that a setting operation for screen brightness input by the user is detected. If the screen brightness is set through voice, the brightness value input by the user through voice can be obtained, and the brightness value is used as a second brightness value.
And step 130, comparing the second brightness value with the first brightness value, and determining whether a preset time window mechanism is enabled according to the comparison result.
It should be noted that the time window mechanism includes: and updating the screen brightness according to the second brightness value, and prompting a user to adjust the screen brightness if the time for maintaining the second brightness of the screen exceeds a preset time threshold.
Illustratively, the second luminance value is compared to the first luminance value in magnitude. If the intensity of the ambient light is lower than a preset light intensity threshold value, namely the current environment is a dark environment, and the second brightness value is larger than the first brightness value, controlling the screen brightness adjusting mode to be switched from the automatic adjusting mode to the manual adjusting mode; in addition, an enabling event of the time window mechanism is triggered, and the intelligent terminal is determined to be in the abnormal brightness state. 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 after the enabling event is triggered, the operation of enabling the preset time window mechanism is executed.
It should be noted that, if the current environment is a dark environment and the second luminance value is lower than the first luminance value, the preset time window mechanism is not enabled, and it is determined that the intelligent terminal is in a normal luminance state.
Alternatively, assuming that the current environment is a dark environment, an absolute value of a difference between the second luminance value and the first luminance value is calculated, and the absolute value is compared with a preset data threshold. If the absolute value exceeds a preset data threshold, controlling the screen brightness adjusting mode to be switched from the automatic adjusting mode to the manual adjusting mode; in addition, an enabling event of the time window mechanism is triggered, and the intelligent terminal is determined to be in the abnormal brightness state. In order to avoid great damage to the eyesight of the user, the preset data threshold value can be set to be smaller, that is, the user can be allowed to slightly adjust the screen brightness, so that the screen brightness and the first brightness value generate small-range deviation, at this time, as the second brightness value adjusted by the user is close to the first brightness value, great damage to the eyesight of the user cannot be caused, and the enabling event of the preset time window mechanism cannot be triggered.
Illustratively, if the intensity of the ambient light is higher than a 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 screen brightness adjustment mode is controlled to be switched from the automatic adjustment mode to the manual adjustment mode; in addition, an enabling event of the time window mechanism is triggered, and the intelligent terminal is determined to be in the abnormal brightness state. It should be noted that, if the intensity of the ambient light 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 after the enabling event is triggered, the operation of enabling the preset time window mechanism is executed.
Alternatively, assuming that the current environment is a bright environment, an absolute value of a difference between the second luminance value and the first luminance value is calculated, and the absolute value is compared with a preset data threshold. If the absolute value exceeds a preset data threshold, controlling the screen brightness adjusting mode to be switched from the automatic adjusting mode to the manual adjusting mode; in addition, an enabling event of the time window mechanism is triggered, and the intelligent terminal is determined to be in the abnormal brightness state.
It should be noted that the adjustment policy includes: when the continuous existence time of the abnormal brightness state is greater than or equal to a preset threshold value, outputting prompt information for adjusting the current screen brightness; and when the continuous existence time of the brightness abnormal state is less than a preset threshold value, disabling the time window mechanism.
The preset threshold may be a default value of the system, and may be adjusted according to the usage habit of the user. For example, historical operating data of the user for the prompt message within a set period of time (e.g., may be one month) is collected. And classifying the historical operation data, extracting features and the like by adopting a data analysis mode, and determining what the user usually inputs the prompt information. If the user's input operation for the prompt message is usually a positive indication, i.e., adjusting the screen brightness, the system default value is maintained. If the user's input operation for the prompt message is usually a negative indication, i.e. the adjustment of the screen brightness is abandoned, the preset threshold is increased, for example, the preset threshold may be adjusted to 1 hour, assuming that the original preset threshold is 30 minutes.
For example, if an enabling event of the time window mechanism is detected, the time window mechanism is enabled, that is, the duration of the intelligent terminal in the abnormal brightness state is recorded. Wherein the brightness abnormal state comprises: if the current environment is a dark environment and the second brightness value is greater than the first brightness value, determining that the intelligent terminal is in an abnormal brightness state; or, assuming that the current environment is a dark environment, calculating an absolute value of a difference value between the second brightness value and the first brightness value, and if the absolute value exceeds a preset data threshold, determining that the intelligent terminal is in an abnormal brightness state; or if the current environment is a bright environment and the second brightness value is smaller than the first brightness value, determining that the intelligent terminal is in an abnormal brightness state; or, assuming that the current environment is a bright environment, calculating an absolute value of a difference value between the second brightness value and the first brightness value, and if the absolute value exceeds a preset data threshold, determining that the intelligent terminal is in an abnormal brightness state.
The duration is a time during which the abnormal brightness state continues to exist.
And outputting prompt information for adjusting the current screen brightness when the duration is greater than or equal to a preset threshold. For example, if the current environment is a dark environment, the duration that the second brightness value is greater than the first brightness value is recorded, and if it is detected that the screen brightness is adjusted to the first brightness value by the user in the timing process, or the screen brightness is adjusted to a third brightness value lower than the first brightness value, the timing is stopped. And acquiring the duration of the second brightness value larger than the first brightness value, and comparing the duration with a preset threshold. And if the duration that the second brightness value is greater than the first brightness value is greater than a preset threshold, outputting 'your current screen is brighter, and the suggestion is to restore to the default brightness'. The default brightness is the screen brightness corresponding to the current ambient light intensity, i.e. the default brightness can be regarded as the first brightness value.
And when the duration is less than a preset threshold, disabling the time window mechanism. For example, if the current environment is a dark environment and the duration of the second luminance value greater than the first luminance value is less than the preset threshold, the time window mechanism is disabled, i.e., disappears, and the duration is set to zero, so that the duration of the abnormal luminance state is accurately recorded when the abnormal luminance state occurs next time the second luminance value is greater than the first luminance value.
According to the technical scheme of the embodiment, the screen brightness of the intelligent terminal is adjusted to a first brightness value according to the ambient light intensity; when the setting operation aiming at the screen brightness input by a user is detected, acquiring a second brightness value corresponding to the setting operation; and comparing the second brightness value with the first brightness value, determining whether a preset time window mechanism is started or not according to the comparison result, executing an adjustment strategy corresponding to the time window mechanism, and adjusting the screen brightness through the adjustment strategy after the situation that the screen brightness is not matched with the current ambient light intensity occurs, so that the situation that the adjustment operation of the screen brightness is not intelligent enough is avoided, and the problem that a user is easy to fatigue when staring at a screen which is not suitable for the current ambient light intensity for a long time is solved.
Fig. 2 is a flowchart of another method for adjusting screen brightness according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
Illustratively, after the time window mechanism is enabled, it is detected whether the ambient light intensity of the ambient environment has changed greatly, and if so, no large change occurs, step 205 is executed. Conversely, if a large change occurs, it may cause the time window mechanism to no longer apply, and step 212 is performed accordingly.
It should be noted that this step is not necessarily performed, and in some examples, this step may not be performed, and step 205 may be directly performed.
And step 205, recording the duration of the intelligent terminal in the abnormal brightness state.
If the ambient light intensity of the current environment is lower than the preset light intensity threshold, namely the dark environment, starting a timer when the second brightness value is larger than the first brightness value, stopping the timer when the second brightness value is detected to be smaller than the first brightness value, and reading the value of the timer 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, that is, the current environment is a bright environment, the timer is started when the second brightness value is smaller than the first brightness value, the timing is stopped when it is detected that the second brightness value is larger than the first brightness value, and the value of the timer is read as the duration of the abnormal brightness state.
Alternatively, the absolute value of the difference between the second luminance value and the first luminance value is calculated. And starting a timer when the absolute value is greater than a preset data threshold, stopping the timer when the absolute value is less than the preset data threshold, and reading the value of the timer as the duration of the abnormal brightness state.
The preset threshold value can be a system default value, can be adjusted according to the use habit of a user, can determine the application environment of the intelligent terminal according to the ambient light intensity of the current environment, and obtains the preset threshold value corresponding to the application environment of the intelligent terminal. For example, the corresponding relationship between the scene and the preset threshold may be preset, that is, the scene without lighting at night, the scene with lighting at night, the indoor scene during the day, the outdoor scene during the day, and the like may be distinguished, and different preset thresholds may be set for different scenes.
And comparing the duration with a preset threshold value. If the duration is not less than the predetermined threshold, step 207 is executed.
And step 207, outputting the prompt information for adjusting the current screen brightness.
And outputting prompt information for adjusting the current screen brightness when the duration is greater than or equal to a preset threshold. For example, when the duration is greater than the preset threshold, the pop-up window reminds the user that "you are on the screen brighter, suggesting a return to default brightness".
And step 208, acquiring a user operation instruction.
The user operation instruction comprises a positive instruction and a negative instruction, the positive instruction is used for indicating that the intelligent terminal is allowed to respond to the prompt message to perform automatic adjustment of the screen brightness, and the negative instruction is used for indicating that the intelligent terminal is not allowed to respond to the prompt message to perform automatic adjustment of the screen brightness.
It is determined whether the user operation instruction is to adjust the screen brightness, and if yes, step 210 is executed.
And 210, adjusting the screen brightness to the first brightness value, and controlling the screen brightness adjusting mode to be switched from the manual adjusting mode to the automatic adjusting mode.
And if the user operation instruction is to adjust the screen brightness, acquiring a first brightness value, and updating the screen brightness according to the first brightness value. In addition, the screen brightness adjusting mode is controlled to be switched from the manual adjusting mode to the automatic adjusting mode, so that whether the current screen brightness is suitable for the current ambient light intensity or not is verified according to the ambient light intensity collected by the light sensor. And if the screen brightness is detected not to be matched with the current ambient light intensity, automatically updating the screen brightness according to the brightness level matched with the current ambient light intensity.
And step 211, maintaining the value of the screen brightness unchanged.
And if the user operation indicates that the screen brightness is not adjusted, maintaining the screen brightness as the second brightness value. In addition, the screen brightness adjusting mode can be maintained to be the manual adjusting mode.
And when the duration is less than the preset threshold, controlling the time window mechanism to disappear, namely disabling the time window mechanism. Optionally, after the time window mechanism is disabled, if the current screen brightness adjustment mode is the manual mode, the screen brightness adjustment mode may be automatically switched to the automatic adjustment mode.
According to the technical scheme of the embodiment, after the time window mechanism is started, whether the ambient light intensity of the surrounding environment is changed greatly or not is additionally detected, and whether the time window mechanism is still applicable or not is determined according to the detection result, so that the error adjustment of the screen brightness under the condition that the time window mechanism is not applicable is avoided, and the adjustment accuracy is improved. In addition, after the prompt information for adjusting the current screen brightness is output, the operation of the user operation instruction is additionally acquired, so that the corresponding adjustment is performed on the screen brightness according to the user operation instruction, the screen brightness can be intelligently adjusted after the situation that the screen brightness is not matched with the current ambient light intensity occurs, the situation that the adjustment operation of the screen brightness is not intelligent enough is avoided, and the problem that the user is easy to fatigue due to the fact that the user stares at a screen which is not suitable for the current ambient light intensity for a long time is solved.
Fig. 3 is a diagram illustrating another method for adjusting screen brightness according to an embodiment of the present application. As shown in fig. 3, the method includes:
301, adjusting the screen brightness of the intelligent terminal to a first brightness value according to the ambient light intensity.
And 305, acquiring the current ambient light intensity by the light sensor, comparing the ambient light intensity with a preset light intensity threshold, and determining the starting time of the timer according to the comparison result.
Illustratively, the current ambient light intensity is obtained by a light sensor. If the intensity of the ambient light is lower than a preset light intensity threshold, starting a timer when the second brightness value is higher than the first brightness value; if the intensity of the ambient light is higher than a preset light intensity threshold, a timer may be started when the second brightness value is smaller than the first brightness value.
And step 306, timing through a timer.
After the timer is started, that is, during the time counting, if it is detected that the user has input the setting operation for the screen brightness again, the brightness value corresponding to the position where the brightness adjustment bar is located may be taken as the third brightness value when the setting operation is finished. Alternatively, a brightness value input by the user or the like may also be acquired.
And 308, determining whether the ambient 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 obtained by a light sensor.
And comparing the intensity of the ambient light with a preset light intensity threshold value to determine whether the current environment is a dark environment or a bright environment.
It should be noted that this step is not necessarily performed, and step 309 may be directly performed.
It should be noted that, if the intensity of the ambient light is higher than the preset light intensity threshold, this step may be replaced by determining whether the third brightness value is greater than the first brightness value.
Alternatively, whether the ambient light intensity is lower than or higher than the preset light intensity, this step may be replaced by calculating a difference between the third brightness and the first brightness value, and comparing an absolute value of the difference with a preset data threshold. If the absolute value of the difference is smaller than the predetermined data threshold, step 310 is executed.
It should be noted that there are many types of timing methods, and the method is not limited to the method using the timer described in the present embodiment. For example, the system time may be read once when a condition for starting the timer is satisfied, the system time may be read once again when a condition for ending the timer is satisfied, and the duration may be determined based on a time difference between the two times of reading the system time.
And 311, reading the value of the timer as the duration of the brightness abnormal state.
And 313, outputting prompt information for adjusting the current screen brightness.
And step 314, acquiring a user operation instruction.
And step 316, adjusting the screen brightness to the first brightness value, and controlling the screen brightness adjustment mode to be switched from the manual adjustment mode to the automatic adjustment mode.
And step 317, keeping the value of the screen brightness unchanged.
According to the technical scheme of the embodiment, after the user manually adjusts the screen brightness, if the screen brightness adjustment operation is input again, a third brightness value corresponding to the screen brightness adjustment operation is obtained, the third brightness value is compared with the first brightness value, if the third brightness value is higher than the first brightness value, timing is continued, if the third brightness value is lower than the first brightness value, timing is stopped, namely during timing, no matter how many times the user manually adjusts the screen brightness, as long as the adjusted screen brightness value is higher than the first brightness value, timing is continued, and the duration time of screen brightness abnormality is obtained according to the timing value; and when the duration meets the adjustment condition, reminding the user to restore the screen brightness to the default setting, and avoiding the situation that the user stares at the screen which is not suitable for the current ambient light intensity for a long time and is easy to generate fatigue.
