Referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting brightness of a display screen according to an embodiment of the present disclosure, where the method for adjusting brightness of a display screen can be applied to the electronic device shown in fig. 1.
As shown in the figure, the display screen brightness adjusting method includes the following operations.
S201, when detecting that a brightness automatic adjusting function is started for a preset time length, the electronic equipment determines a first brightness curve according to detected user brightness adjusting operation, wherein the brightness automatic adjusting function is used for adjusting the brightness of a display screen according to a reference brightness curve by the electronic equipment within the preset time length;
the specific implementation manner of starting the brightness automatic adjustment function may be various, for example, gesture operation of the user may be detected, and the brightness automatic adjustment function is started according to a gesture corresponding to the detected brightness automatic adjustment function, or it may be detected that the brightness of the display screen has not been adjusted within a preset time period, for example, within the last week, within five days, and the like, the brightness automatic adjustment function is automatically started, and the like, which is not limited herein.
The preset time period may be set in the electronic device according to an empirical value when the electronic device is shipped from a factory by a technical research and development worker, and may be, for example, half a day, one day, two days, and the like, which is not limited herein.
The brightness automatic adjustment function is a function that the electronic device automatically adjusts the brightness of the display screen according to the detected light intensity of the ambient light and a brightness curve, for example, in the preset time period, the electronic device automatically adjusts the brightness of the display screen according to the detected light intensity of the ambient light and a reference brightness curve, where the reference brightness curve is a default brightness curve of the electronic device and is set in the electronic device by a technician of the electronic device before the electronic device leaves a factory, and when it is detected that a user starts the brightness automatic adjustment function, the brightness curve used by the electronic device.
The luminance curve is an algorithm curve used by the luminance auto-adjustment function, i.e., y ═ f (x), where x is the input light intensity and y is the output luminance value, e.g., the reference luminance curve, the first luminance curve, the second luminance curve, etc.
Wherein the user brightness adjustment operation comprises a brightness increase operation and a brightness decrease operation.
The specific implementation manner of determining the first brightness curve according to the detected user brightness adjustment operation may be various, for example, the first brightness curve may be determined by adjusting the reference brightness curve according to the amplitude of each brightness adjustment of the user within the preset time period, or the first brightness curve may be determined according to the maximum brightness value and the minimum brightness value when the user adjusts the brightness within the preset time period, and the like, and no determination is made here.
S202, the electronic equipment reduces the first brightness curve by a first adjustment amount to obtain a second brightness curve;
the first adjustment amount may be, for example, 10%, 5%, or the like, and is not limited herein.
The specific implementation manner of the electronic device that decreases the first luminance curve by the first adjustment amount to obtain the second luminance curve is to decrease the rate of change of the luminance value of the first luminance curve with the light intensity by the first adjustment amount, for example, when the first adjustment amount is 10%, the first luminance curve is y ═ f (x), and the second luminance curve is y ═ 0.9f (x).
S203, the electronic equipment adjusts the brightness of the display screen according to the second brightness curve so as to brighten the screen.
It can be seen that, in the embodiment of the application, when detecting that the automatic brightness adjustment function is started for a preset time duration, the electronic device determines a first brightness curve according to the detected user brightness adjustment operation, where the automatic brightness adjustment function is used for adjusting the brightness of the display screen according to a reference brightness curve by the electronic device within the preset time duration; reducing the first brightness curve by a first adjustment amount to obtain a second brightness curve; and brightening the screen according to the second brightness curve. Therefore, after the brightness automatic adjusting function of the electronic equipment is started, the first brightness curve adaptive to the user person is determined according to the brightness adjusting operation of the user, the intelligence of the brightness automatic adjusting function is favorably improved, the first brightness curve is slightly reduced to a certain degree according to the first adjusting amount to obtain the second brightness curve, and the screen is lightened according to the second brightness curve, so that the brightness adjustment meets the personal use habit of the user, and meanwhile, the power consumption of the electronic equipment is reduced.
In one possible example, the determining a first brightness profile according to the detected user brightness adjustment operation includes:
acquiring a first brightness adjustment frequency of the user for the electronic equipment in the preset time length and the amplitude of each brightness adjustment;
and adjusting the reference brightness curve according to the first brightness adjustment times and the amplitude of each brightness adjustment to obtain the first brightness curve.
The first brightness adjustment times comprise brightness adjustment times and brightness adjustment times.
The specific implementation manner of adjusting the reference luminance curve according to the first luminance adjustment number and the amplitude of each luminance adjustment to obtain the first luminance curve may be, for example, when the first luminance adjustment number is less than the reference number, not adjusting the reference luminance curve, that is, the reference luminance curve is the first luminance curve, when the first luminance adjustment number is greater than or equal to the reference number, adjusting the reference luminance curve according to the amplitude of each luminance adjustment to obtain the first luminance curve, specifically, the specific implementation manner of adjusting the reference luminance curve according to the amplitude of each luminance adjustment to obtain the first luminance curve may be various, for example, the luminance value after each luminance adjustment may be determined by the amplitude of each luminance adjustment, the luminance value after multiple adjustments is linearly fitted to obtain the first luminance curve, or the average amplitude of multiple luminance adjustments may be determined, the first brightness curve is obtained by adjusting the rate of change of the brightness value along with the light intensity in the reference curve according to the average amplitude, which is not limited herein.
Therefore, in this example, when the electronic device is turned on with the reference brightness curve, the brightness adjustment action of the user is obtained, the reference brightness curve is adjusted, so that the brightness is automatically adjusted to meet the personal use habit of the user, and the intelligence of the brightness adjustment is improved.
In one possible example, after the dimming the first brightness curve by the first adjustment amount to obtain a second brightness curve, the method further includes:
determining a second brightness adjustment frequency of the user for a second brightness curve in the current processing period, wherein the brightness before brightness adjustment corresponding to each brightness adjustment in the second brightness adjustment frequency is smaller than the brightness after brightness adjustment;
and updating the second brightness curve according to the second brightness adjusting times.
Wherein the second brightness adjustment times only include brightness increase times.
The current processing period is from the last time the second brightness curve is updated to the current time point, and may be, for example, one week, one month, and the like, which is not limited herein.
The specific implementation manner of updating the second brightness curve according to the second brightness adjustment number may be various, for example, the second brightness curve may not be updated when the second brightness adjustment number is smaller than a preset number threshold, or the second brightness curve may be continuously adjusted down, which is not limited herein, and the second brightness curve is adjusted up when the second brightness adjustment number is greater than or equal to the preset number threshold.
The electronic device determines, in each processing period, a second brightness adjustment number of the user for a second brightness curve in the current processing period, and then periodically cycles all operations until the cycle is ended, where the cycle end operation is, for example, that a brightness minimum value corresponding to the second brightness curve described below is smaller than a preset brightness threshold value.
Therefore, in this example, after the first brightness curve is reduced, the electronic device continues to observe the brightness adjustment operation of the user after the brightness of the display screen is automatically adjusted by using the first brightness curve, and updates the second brightness curve according to the brightness adjustment operation of the user, so that the reduction of the user experience caused by the reduction of the first brightness curve is avoided, and the rationality of brightness adjustment is improved.
In this possible example, the updating the second brightness curve according to the second brightness adjustment number includes:
judging whether the second brightness adjustment times are larger than a preset time threshold value or not;
if the second brightness adjusting times are smaller than or equal to the preset times threshold, acquiring a current second brightness curve;
judging whether the minimum brightness value corresponding to the second brightness curve is larger than a preset brightness threshold value or not;
and if the minimum brightness value corresponding to the second brightness curve is larger than the preset brightness threshold, reducing the second brightness curve according to a second adjustment amount to update the second brightness curve.
The preset number threshold and the preset brightness threshold are set in the electronic device by a technician of the electronic device according to experience values before the electronic device leaves a factory, for example, the preset number threshold may be 8, 9, 10, and the like, and the preset brightness threshold may be 30, 20, and the like, which is not limited herein.
The specific implementation manner of the electronic device lowering the second luminance curve according to the second adjustment amount is to decrease the rate of change of the luminance value of the second luminance curve with the light intensity by the first adjustment amount, for example, when the second adjustment amount is 5%, the second luminance curve is y ═ f (x), and the updated second luminance curve is y ═ 0.95f (x).
After determining whether the minimum brightness value corresponding to the second brightness curve is greater than a preset brightness threshold, the method further includes: and if the minimum brightness value corresponding to the second brightness curve is smaller than the preset brightness threshold, not updating the second brightness curve, and simultaneously not executing the operation of determining the second brightness adjustment frequency of the user for the second brightness curve in the current processing period and all the subsequent operations until the user closes the automatic brightness adjustment function.
As can be seen, in this example, when the number of times of adjusting the second brightness is less than or equal to the preset number threshold, that is, it indicates that the user can accept to lower the second brightness curve of the first brightness curve, and meanwhile, the minimum brightness value corresponding to the second brightness curve is greater than the preset brightness threshold, that is, the brightness is not too low, the second brightness curve can be continuously lowered, and the power consumption of the electronic device is further reduced in the range received by the user.
In this possible example, before the dimming the second brightness curve according to the second adjustment amount to update the second brightness curve, the method further includes:
determining a brightness value interval corresponding to the second brightness curve;
and determining the second adjustment amount according to the brightness value interval.
The brightness value interval is an interval between a maximum brightness value and a minimum brightness value in the second brightness curve, different brightness value intervals may correspond to different second adjustment amounts, for example, the higher the maximum brightness value in the brightness value interval is, the larger the corresponding second adjustment amount is, in a specific implementation, the electronic device may include a mapping relationship between the brightness value interval and the second adjustment amount, and the electronic device may query the mapping relationship according to the brightness value interval to determine the second adjustment amount.
It can be seen that, in this example, the electronic device determines the second adjustment amount according to the luminance value interval corresponding to the second luminance curve, instead of using the fixed second adjustment amount, which is beneficial to improving the flexibility and the rationality of the luminance curve determination.
In one possible example, after determining whether the second brightness adjustment number is greater than a preset number threshold, the method further includes:
if the second brightness adjusting times are larger than the preset times threshold, acquiring a current second brightness curve;
and increasing the second brightness curve according to a third adjustment amount to update the second brightness curve, wherein the third adjustment amount is smaller than the adjustment amount when the second brightness curve is updated in the last processing cycle of the current processing cycle.
The specific implementation manner of the electronic device increasing the second luminance curve according to the third adjustment amount is to increase the rate of change of the luminance value of the second luminance curve with the light intensity by the third adjustment amount, for example, when the second adjustment amount is 5%, the second luminance curve is y ═ 0.9f (x), and the updated second luminance curve is y ═ 0.95f (x).
For example, if the adjustment amount when the second luminance curve is updated in the previous processing cycle of the current processing cycle is the first adjustment amount, the third adjustment amount is smaller than the first adjustment amount, for example, if the first adjustment amount is 10%, the second adjustment amount may be 5%, 8%, and the like, which is not limited herein.
As can be seen, in this example, when the number of times of the second brightness adjustment is greater than the preset number threshold, that is, when the user often feels that the brightness of the display screen adjusted by the second brightness curve that is currently adjusted by the electronic device is low, the electronic device returns the first adjustment amount to make the second brightness curve more suitable for the user, and the first adjustment amount is lower than the adjustment amount of the previous second brightness curve, instead of directly returning to the second brightness curve before updating, a certain amount of power consumption reduction can be ensured in consideration of the user experience.

As shown in the figure, the display screen brightness adjusting method includes the following operations:
