An electronic device in the embodiment of the present application is described below with reference to fig. 1, where fig. 1 is a schematic structural diagram of an electronic device provided in the embodiment of the present application, and the electronic device 100 includes a screen 110, an optical sensing module 120, a processor 130, and a memory 140.
The screen 110 may be a Cathode Ray Tube (CRT) display screen, a liquid crystal display screen, an LED screen, a projection screen, a 3D display screen, and the like, and is not limited herein.
The optical sensing module 120 may include a main optical sensor 121 and a sub optical sensor 122, where the main optical sensor 121 may be an optical sensor disposed on the front surface of the screen 110, and the sub optical sensor 122 may be an optical sensor disposed on the back surface or the side surface of the screen 110, and the number of the main optical sensor 121 and the sub optical sensor 122 is not specifically limited herein. The main light sensor 121 and the sub light sensor 122 may collect ambient light at a preset sampling frequency to obtain a plurality of corresponding first illuminance levels and form a first illuminance level sequence.
The memory 140 may store the first illuminance sequence collected by the optical sensing module 120, and may also store a historical stable illuminance corresponding to a historical display brightness of the screen 110, where the historical display brightness is the current display brightness.
The processor 130 may obtain the first illuminance sequence collected by the optical sensing module 120 and perform corresponding comparison processing on the historical stable illuminance in the memory 140, detect whether the first illuminance sequence satisfies a characteristic of continuous change of a numerical value, and determine a brightness adjustment strategy under various conditions, which is not described herein again. The processor 130 may obtain the first illumination sequence and the historical steady illumination from the optical sensor module 120 and the memory 140 to determine the target display brightness, and adjust the brightness of the screen 110 to the target display brightness.
Therefore, through the electronic equipment, the ambient light change trend can be determined more accurately, the target display brightness is determined based on the ambient light change trend, the brightness of the screen can be adjusted, the display brightness of the screen can be dynamically adjusted according to different ambient light scenes, shaking caused by frequent brightness change is prevented, and user experience is improved.
Next, a brightness adjustment method in the embodiment of the present application is described with reference to fig. 2, where fig. 2 is a schematic flow chart of the brightness adjustment method provided in the embodiment of the present application, and specifically includes the following steps:
The first illumination sequence comprises a sequence of a plurality of first illuminations acquired according to a sampling sequence aiming at ambient light, the historical display brightness is used for indicating the current display brightness of the screen, and the historical stable illumination is used for indicating the illumination of the historical ambient light when the historical display brightness is determined.
Specifically, the historical display brightness and the historical stable illuminance can be determined according to the current brightness of the screen, then, ambient light is collected at preset time intervals to obtain a plurality of real-time illuminance sets corresponding to a plurality of timestamps, then, the real-time illuminance sets are subjected to fusion calculation to obtain a first illuminance corresponding to each timestamp, and finally, the first illuminance corresponding to each timestamp is arranged in the sampling sequence to obtain the first illuminance sequence.
For example, the current brightness of the screen may be obtained as 100lux, the historical ambient light data when the historical display brightness of the screen is determined as 100lux is called to determine the historical stable illuminance, and the ambient light may be collected by the light sensing module at a preset time interval of 0.2 second to obtain the first illuminance sequence, where it is understood that the number of the first illuminance in the first illuminance sequence is continuously increased, and the number of the first illuminance in the first illuminance sequence is not specifically limited.
In a possible embodiment, the optical sensing module may include a main optical sensor disposed on the front side of the screen and a sub optical sensor disposed on the back side of the screen, and since the sampling times of the main optical sensor and the sub optical sensor may not be completely consistent, generally, the illuminance of the collected ambient light is reported alternately, a fusion calculation may be performed on the illuminance reported by the main optical sensor and the illuminance reported by the sub optical sensor, for example, first, the main optical sensor uploads a first illuminance a1, the illuminance a1 may be used as a first illuminance and added to a first illuminance sequence, then, the sub optical sensor uploads a second illuminance b1, at this time, a1 and b1 may be compared, and a larger value is added to the first illuminance sequence as a second first illuminance, and if b1 is larger, b1 is added to the first illuminance sequence as a second first illuminance, then the main light sensor uploads a third illuminance a2, if a2 is greater than b1, a2 is added to the first illuminance sequence as the third first illuminance, then the sub-light sensor uploads a fourth illuminance b2, if b2 is less than a2, a2 is still added to the first illuminance sequence as the fourth first illuminance, and thus the first illuminance sequence is { a1, b1, a2, a2}, and so on, which is not described herein again. It should be noted that, if the main light sensor and the sub light sensor are set to collect the ambient light at a preset time interval of 0.2s, the consumed time period should be 0.4 s plus the sampling time difference between the main light sensor and the sub light sensor when the four first illumination intensities are determined.
It is understood that the above a1, a2, a3, b1, b2 and b3 only indicate the value of the illuminance, and do not have any meaning. Therefore, the most accurate illuminance can be obtained to form a first illuminance sequence, and smooth transition of the acquired illuminance is ensured.
Therefore, the historical stable illuminance corresponding to the historical display brightness of the screen is obtained, and the first illuminance sequence is obtained, so that the brightness change can be prevented from being too frequent,
The numerical value continuous change characteristic is used for representing that the first illuminance changes from large to small and the first illuminance with the first sampling sequence is smaller than the historical stable illuminance, or is used for representing that the first illuminance changes from small to large and the first illuminance with the first sampling sequence is larger than the historical stable illuminance.
Specifically, the above-described numerical value continuous change characteristic includes an upward tendency characteristic and a downward tendency characteristic.
When the plurality of first illuminance sequences are detected to be arranged from small to large according to the numerical value, and a first illuminance in the first illuminance sequence is larger than the historical stable illuminance, determining that the first illuminance sequence meets the ascending trend characteristic; or when the plurality of first illuminance sequences are detected to be arranged from large to small according to the numerical value, and the first illuminance in the first illuminance sequence is smaller than the historical stable illuminance, determining that the first illuminance sequence meets the descending trend characteristic;
when it is detected that the plurality of first illuminance are not arranged from small to large or from large to small according to the magnitude of the numerical value, or when it is detected that a first illuminance in the first illuminance sequence is smaller than the historical stable illuminance but any one of the first illuminance is larger than the first illuminance, or when it is detected that the first illuminance in the first illuminance sequence is larger than the historical stable illuminance but any one of the first illuminance is smaller than the first illuminance, it is determined that the first illuminance sequence does not satisfy the numerical value continuous change characteristic.
For example, the historical steady illuminance is 40lux, and when the first illuminance sequence is {50, 60, 70, 80}, it may be determined that the first illuminance sequence satisfies the ascending trend characteristic; when the first illuminance sequence is {30, 25, 20, 10}, it may be determined that the first illuminance satisfies a falling tendency characteristic; when the first light intensity sequence is {30, 50} or {50, 30}, it may be determined that the first light intensity sequence does not satisfy the numerical value continuous variation characteristic.
Therefore, whether the first illuminance sequence meets the characteristic of continuous change of numerical values or not is detected according to the first illuminance sequence and the historical stable illuminance, the change trend of the ambient light can be determined, the appropriate display brightness can be conveniently determined, and the user experience is improved.
When the first illuminance sequence meets the ascending trend characteristic, selecting a first preset number of first illuminances to perform root mean square calculation to obtain a first root mean square illuminance, and performing standard deviation calculation on the first root mean square illuminance to obtain a second illuminance; or the like, or, alternatively,
when the first illuminance sequence meets the descending trend characteristic and the historical stable illuminance is greater than a preset illuminance threshold value, selecting a second preset number of first illuminances to perform root mean square calculation to obtain a second root mean square illuminance, and performing standard deviation calculation on the second root mean square illuminance to obtain the second illuminance; or the like, or, alternatively,
when the first illuminance sequence meets the descending trend characteristic and the historical stable illuminance is smaller than or equal to the preset illuminance threshold value, selecting a third preset number of first illuminances to perform root mean square calculation to obtain a third root mean square illuminance, and performing standard deviation calculation on the third root mean square illuminance to obtain the second illuminance.
When the first illuminance of the first preset number is obtained, a first preset time period is required to be consumed, and the value of the first preset time period can be the product of the first preset number and a preset time interval; when the first illuminance of the second preset number is obtained, a second preset time period needs to be consumed, and the value of the second preset time period can be the product of the second preset number and the preset time interval; when the first illuminance of the third preset number is obtained, a third preset time period needs to be consumed, and the value of the third preset time period may be the product of the third preset number and the preset time. And then summing the squares of the obtained first illuminance, squaring to obtain a first root-mean-square illuminance, a second root-mean-square illuminance or a third root-mean-square illuminance, and calculating the standard deviation of the first root-mean-square illuminance, the second root-mean-square illuminance or the third root-mean-square illuminance to obtain the second illuminance. The preset illuminance threshold may be a dark light limit, and if the preset illuminance threshold is lower than or equal to the preset illuminance threshold, the environment is determined to be in a dark light environment, and if the preset illuminance threshold is higher than the preset illuminance threshold, the environment is not in a dark light environment.
For example, when the first illuminance sequence meets the ascending trend characteristic, when the number of the first illuminances is greater than 4 and the first preset duration is greater than 0.8 second, selecting a first preset number (namely 4) of the first illuminances to perform root mean square calculation to obtain a first root mean square illuminance, and then performing standard deviation calculation on the first root mean square illuminance to obtain a second illuminance;
when the first illuminance sequence meets the descending trend characteristic and the historical stable illuminance is greater than a preset illuminance threshold value, when the number of the first illuminance is greater than 6 and the first preset time is greater than 1.2 seconds, selecting a second preset number (namely 6) of the first illuminance to perform root mean square calculation to obtain a second root mean square illuminance, and then performing standard deviation calculation on the second root mean square illuminance to obtain a second illuminance;
when the first illuminance sequence meets the descending trend characteristic and the historical stable illuminance is less than or equal to a preset illuminance threshold value, when the number of the first illuminance is greater than 10 and the first preset time is greater than 2 seconds, selecting a third preset number (namely 10) of the first illuminance to perform root mean square calculation to obtain a third root mean square illuminance, and then performing standard deviation calculation on the second root mean square illuminance to obtain a second illuminance.
The above calculation process of the root mean square can refer to the existing root mean square formula, and is not described herein.
The second illuminance may be calculated by the following formula:
second illuminance-root mean square illuminance-average illuminance/1 + standard deviation
The rms illuminance may be a first rms illuminance, a second rms illuminance, or a third rms illuminance, the average illuminance may be a first average illuminance, a second average illuminance, or a third average illuminance, and the standard deviation may be a first standard deviation, a second standard deviation, or a third standard deviation.
It will be appreciated that the above-described,
the first average illuminance is equal to the sum of the first illuminance of the first preset number/the first preset number
The second average illuminance is equal to the sum of the first illuminance of the second preset number/the second preset number
The third average illuminance is equal to the sum of the third preset number of the first illuminance/the third preset number
The calculation method of the standard deviation can be referred to the existing standard deviation formula, and is not described herein again.
Therefore, different second illuminance calculation methods are set for the ascending trend characteristic, the descending trend characteristic in a non-dark light state and the descending trend characteristic in a dark light state respectively, so that the updating of the brightness is not too sensitive, the weighted illuminance close to the actual illuminance can be obtained through the root mean square calculation, the weighted illuminance is closer to the actual light of the environment, and the influence of the light sensation pulse signal on the illuminance of the whole body can be eliminated through the standard deviation calculation.
And 204, determining the target display brightness according to the difference value between the second illumination and the historical stable illumination.
Determining a first display brightness corresponding to the second illuminance, wherein the first display brightness represents an ideal display brightness under the second illuminance, and determining a first illuminance change interval and a second illuminance change interval corresponding to the historical stable illuminance, wherein the first illuminance change interval is smaller than the second illuminance change interval;
when the difference value between the second illuminance and the historical stable illuminance does not exceed the first illuminance change interval, determining the historical display brightness as the target display brightness; when the difference value between the second illuminance and the historical stable illuminance exceeds the first illuminance change interval and does not exceed the second illuminance change interval, multiplying the first display brightness by an anti-shake coefficient to obtain the target display brightness; and when the difference value between the second illuminance and the historical stable illuminance exceeds the second illuminance change interval, determining the first display brightness as the target display brightness.
For example, the anti-shake coefficient is 0.6, the historical steady illumination is 50lux, the first illumination variation interval is [45lux, 55lux ], and the second illumination variation interval is [30lux, 70lux ]. When the first display brightness belongs to [45lux, 55lux ], it may be determined that the target display brightness is still 50 lux; when the first display luminance exceeds [45lux, 55lux ] but does not exceed [30lux, 70lux ], it may be determined that the target display luminance is 0.6; when the first display luminance exceeds [30lux, 70lux ], it may be determined that the target display luminance is equal to the first display luminance.
Therefore, different illuminance change intervals are set, and better anti-shake and sensitivity balance can be realized according to the adaptability of human eyes to the environment.
As can be seen, in the brightness adjustment method, first, a historical stable illuminance corresponding to a historical display brightness of a screen is obtained, and a first illuminance sequence is obtained, where the first illuminance sequence includes a sequence of a plurality of first illuminances acquired by collecting ambient light according to a sampling order, the historical display brightness is used to indicate a current display brightness of the screen, and the historical stable illuminance is used to indicate an illuminance of the historical ambient light when the historical display brightness is determined; then, whether the first illuminance sequence meets a numerical value continuous change characteristic is detected according to the first illuminance sequence and the historical stable illuminance, wherein the numerical value continuous change characteristic is used for representing that the first illuminance changes from large to small and the first illuminance with the first sampling sequence is smaller than the historical stable illuminance, or is used for representing that the first illuminance changes from small to large and the first illuminance with the first sampling sequence is larger than the historical stable illuminance; then, if the first illuminance sequence meets the characteristic of continuous change of numerical values, determining second illuminance according to the plurality of first illuminances and the historical stable illuminance; then, determining target display brightness according to the difference value between the second illuminance and the historical stable illuminance; and finally, adjusting the display brightness of the screen according to the target display brightness. The display brightness of the screen can be dynamically adjusted according to different ambient light scenes, shaking caused by frequent brightness change is prevented, and user experience is improved.
Next, another brightness adjustment method in the embodiment of the present application is described with reference to fig. 3, where fig. 3 is a schematic flow chart of another brightness adjustment method provided in the embodiment of the present application, and specifically includes the following steps:
If the first illuminance sequence satisfies the characteristic of continuous variation of numerical values, go to step 306; if the first illuminance sequence does not satisfy the characteristic of continuous variation of numerical values, step 303 is executed.
It is understood that each time a first illuminance is acquired, whether the first illuminance sequence satisfies the numerical continuous variation characteristic is detected, so when the first illuminance sequence is detected not to satisfy the numerical continuous variation characteristic, the last first illuminance can be determined as noise data, and the noise data can be ignored and is not included in the first illuminance sequence.
It can be seen that, when the first sequence of illuminance does not satisfy the numerical value continuous variation characteristic, the last first illuminance in the first sequence of illuminance is determined as noise data, and the interference of a slight light variation can be excluded.
The preset noise number threshold may be set according to a requirement, for example, 4 noise data are generated, and when 4 noise data occur in the first illuminance sequence, it may be determined that the ambient light is in a blinking state at this time, and the first illuminance sequence is formed by reacquiring the first illuminance.
Therefore, the display brightness does not change along with the change of the ambient light frequently, and the user experience is improved.
Step 302 is executed continuously, so that the interference caused by the sudden change of the ambient light can be eliminated, and the user experience is improved.
And 308, adjusting the display brightness of the screen according to the target display brightness.
And if the display brightness of the screen is adjusted, the user manually adjusts the display brightness within a preset time period, which indicates that the brightness adjustment does not meet the user requirement, and the anti-shake coefficient needs to be updated iteratively. It can be understood that if the feedback data is not acquired within the preset time period, the anti-shake coefficient does not need to be updated.
And 310, correcting the anti-shake coefficient according to the feedback data.
As can be seen, according to the brightness adjustment method, first, a historical stable illuminance corresponding to a historical display brightness of a screen is obtained, and a first illuminance sequence is obtained, where the first illuminance sequence includes a sequence of a plurality of first illuminances acquired by collecting ambient light according to a sampling order, the historical display brightness is used to indicate a current display brightness of the screen, and the historical stable illuminance is used to indicate an illuminance of the historical ambient light when the historical display brightness is determined; then, whether the first illuminance sequence meets a numerical value continuous change characteristic is detected according to the first illuminance sequence and the historical stable illuminance, wherein the numerical value continuous change characteristic is used for representing that the first illuminance changes from large to small and the first illuminance with the first sampling sequence is smaller than the historical stable illuminance, or is used for representing that the first illuminance changes from small to large and the first illuminance with the first sampling sequence is larger than the historical stable illuminance; then, if the first illuminance sequence meets the characteristic of continuous change of numerical values, determining second illuminance according to the plurality of first illuminances and the historical stable illuminance; then, determining target display brightness according to the difference value between the second illuminance and the historical stable illuminance; and finally, adjusting the display brightness of the screen according to the target display brightness. The display brightness of the screen can be dynamically adjusted according to different ambient light scenes, shaking caused by frequent brightness change is prevented, and user experience is improved.
The steps that are not described in detail above can be referred to the description of the method of all or part of the steps in fig. 2, and are not described again here.
