According to the scheme, when people use the terminal in daily life, after the automatic brightness adjusting function of the display screen is set in the terminal, the terminal realizes the real scene of automatic brightness adjustment of the display screen, and for convenience of understanding, a few nouns and application scenes related to the embodiment of the application are firstly and simply introduced below.
The illumination intensity is as follows: refers to the luminous flux of visible light received per unit area. For short, illuminance is expressed in Lux (Lux or lx). Which may indicate the intensity of the illumination and the degree to which the surface of the object is illuminated.
Light sensation under the screen: the light sensor is arranged below the display screen and is a hardware design scheme.
Brightness: the intensity of light and shade of an object is defined as the luminous intensity per unit area, and the unit is nit (nit), 1 nit is 1 kantera per square meter (cd/m)2)。
With the development of science and technology, more and more terminals appear in people's daily life, and people can work, amusement, study etc. through the terminal. Among them, the display screen is an important component in most terminals, and the adjustment of brightness thereof is one of important aspects of people's attention.
Referring to fig. 1, a schematic interface diagram of a display screen with different brightness in a terminal according to an exemplary embodiment of the present application is shown. As shown in fig. 1, which includes a terminal 110.
Alternatively, the terminal 110 is a terminal mounted with a display screen. For example, the terminal may be a mobile phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP3 player (Moving Picture Experts Group audio Layer III, motion Picture Experts Group audio Layer IV, motion Picture Experts Group audio Layer 4), an MP4 player, a notebook computer, a laptop computer, a desktop computer, and the like.
Optionally, the user may adjust the brightness of the display screen in the terminal 110 by controlling the brightness control, or the terminal 110 may also have a function of automatically adjusting the brightness of the display screen, and when the user opens the function of automatically adjusting the brightness of the display screen in the terminal, the terminal 110 may also adjust the brightness of the display screen by collecting the illumination intensity of the ambient light by itself.
In the related art, the terminal automatically adjusts the brightness of the display screen as follows. The terminal is divided into different brightness levels corresponding to different display screen brightness in advance, and a light sensation anti-shake interval is set for each brightness level and can indicate the change range of the illumination intensity of the ambient light received by the display screen supported by the terminal under a certain brightness level. The terminal can control the brightness change of the display screen through the acquired illumination intensity of the ambient light received by the display screen and the light sensation anti-shake interval. If the illumination intensity of the ambient light received by the display screen acquired by the terminal is within the light sensation anti-shake interval, the terminal cannot adjust the brightness of the display screen, namely, the brightness of the display screen cannot be changed. If the illumination intensity of the ambient light received by the display screen acquired by the terminal is not in the light sensation anti-shake interval, the terminal can adjust the brightness of the display screen, namely, the brightness of the display screen can be changed.
For example, the current brightness of the display screen is 100nit, the light-sensing anti-shake interval corresponding to the brightness value is 80 to 140Lux, and at this time, if the illumination intensity of the ambient light received by the display screen acquired by the terminal is 100Lux, the brightness of the display screen does not change. However, if the illumination intensity of the ambient light received by the display screen acquired by the terminal is 70Lux or 150Lux, the terminal searches for the corresponding brightness according to the illumination intensity of the ambient light received by the display screen acquired here, and sets the brightness of the display screen to the brightness found here.
Under the scheme, the sizes of the light-sensing anti-shake areas set by the terminals are different in the scenes that the display screen is at higher brightness (for example, the brightness of the display screen is not less than 20Lux) and higher brightness (for example, the brightness of the display screen is less than 20 Lux). For example, the current brightness of the display screen is 500nit, the light-sensing anti-shake interval corresponding to 500nit may be 1200 to 2000Lux, the current brightness of the display screen is 16nit, and the light-sensing anti-shake interval corresponding to 16nit may be 20 to 35 Lux.
Wherein, when the brightness of the display screen is 500nit, the probability that the illumination intensity of the ambient light received by the display screen acquired by the terminal jumps repeatedly around the boundary value of the light-sensing anti-shake interval is low, and when the brightness of the display screen is 16nit, the probability that the illumination intensity of the ambient light received by the display screen acquired by the terminal jumps repeatedly around the boundary value of the light-sensing anti-shake interval is high, that is, the illumination intensity of the ambient light received by the display screen acquired by the terminal is influenced by the variation of the illumination intensity in the ambient environment when the brightness of the display screen is 16nit more greatly than the illumination intensity of the ambient light received by the display screen acquired by the terminal when the brightness of the display screen is 500nit, so that the illumination intensity of the ambient light received by the display screen acquired by the terminal is easy to change continuously at the boundary of the light-sensing anti-shake interval, therefore, the brightness of the display screen is continuously adjusted, so that the stroboscopic phenomenon of the display screen is caused, and the display effect of the display screen is reduced.
In order to prevent the problem that the stroboscopic phenomenon occurs to the display screen due to the fact that the acquired light sensation value of the display screen changes on two sides of the boundary value of the light sensation anti-shake interval, the display screen brightness adjusting method can record the light sensation interval corresponding to the illumination intensity through detecting the size relation between the illumination intensity of the display screen acquired by the terminal and the second preset threshold value, and therefore the display effect of the display screen of the terminal is improved.
Referring to fig. 2, a flowchart of a method for adjusting brightness of a display screen according to an exemplary embodiment of the present application is shown. The method can be used in the terminal with the display screen shown in fig. 1, and as shown in fig. 2, the display screen brightness adjusting method can include the following steps.
The current time may be a current time of a display screen of the terminal in a normal working process when the display screen is turned on. Ambient light may refer to light received by the light sensor other than the light of the terminal's own display.
Optionally, in the process that the display screen is lighted up, the terminal may obtain, in real time, the illumination intensity of the ambient light received by the display screen through the optical sensor below the display screen.
The terminal can periodically acquire the light sensation value, when the acquired light sensation value is smaller than a second preset threshold value, the terminal can record a light sensation value, and the target light sensation value can be the light sensation value acquired at this time.
In step 203, when the first light sensation value is within the target light sensation interval, a target light sensation value is obtained.
When the terminal detects that the acquired first light sensation value is within the target light sensation interval, the terminal can acquire the light sensation value recorded when the second light sensation value detected before is smaller than the second preset threshold value. Optionally, the recorded light sensation value is a second light sensation value, that is, when the terminal detects that the second light sensation value is smaller than a second preset threshold, the terminal records the second light sensation value.
And 204, adjusting the brightness of the display screen according to the target light sensation value.
The terminal can use the target light sensation value as a first light sensation value acquired at the current moment, and judge whether the brightness of the display screen needs to be adjusted according to the target light sensation value.
In summary, by acquiring the first light sensation value, the first light sensation value is the illumination intensity of the ambient light received by the display screen at the current moment; detecting whether the first light sensation value is in a target light sensation interval, wherein the target light sensation interval is obtained according to the target light sensation value when the terminal is in a target state, the target state is a state that the pixel values of a preset number of pixel points in a display screen are larger than a first preset threshold value, the target light sensation value is smaller than a second preset threshold value, and the target light sensation value is recorded when the light sensation value obtained last time before the current moment by the terminal is smaller than the second preset threshold value; when the first light sensation value is within the target light sensation interval, acquiring a target light sensation value; and adjusting the brightness of the display screen according to the target light sensation value. This application is through acquireing target light sense interval according to target light sense value, when the first light sense value that the terminal acquireed is in target light sense interval, adjusts the luminance of display screen according to target light sense value, has avoided the terminal directly to adjust the stroboscopic phenomenon that the luminance of display screen brought according to the first light sense value that acquires, has improved the luminance regulation effect of display screen.
In a possible implementation manner, the terminal may indicate whether the terminal is currently in the target state by setting a status flag bit. The above embodiment is described by taking as an example that the terminal needs to detect whether the terminal is in the target state before detecting whether the acquired first light sensation value is within the target light sensation interval.
Referring to fig. 3, a flowchart of a method for adjusting brightness of a display screen according to an exemplary embodiment of the present application is shown. The method can be used in the terminal with the display screen shown in fig. 1, and as shown in fig. 3, the display screen brightness adjusting method can include the following steps.
The first light sensation value is the illumination intensity of the environment light received by the display screen at the current moment.
In practical application, the illumination intensity that the terminal can acquire through the optical sensor is the sum of the illumination intensity of the light emitted by the display screen and the illumination intensity of the ambient light, and if the terminal needs to obtain the illumination intensity of the ambient light, the illumination intensity of the light emitted by the display screen needs to be subtracted from the illumination intensity directly received by the optical sensor. Optionally, the terminal may obtain the brightness of its own display screen, and calculate the illumination intensity of the display screen to the light sensor, so as to obtain the illumination intensity of the ambient light received by the display screen through calculation.
The target state is a state that the pixel values of a preset number of pixel points in the display screen are larger than a first preset threshold value, the target light sensation value is smaller than a second preset threshold value, and the target light sensation value is a light sensation value recorded when a light sensation value acquired by the terminal last time before the current moment is smaller than the second preset threshold value.
Optionally, in this embodiment of the application, a light sensation value that is obtained by the terminal last time before the current time may be referred to as a second light sensation value, that is, the terminal may obtain the second light sensation value before the current time in a manner similar to the manner of obtaining the first light sensation value, and compare the second light sensation value with a second preset threshold, if the terminal detects that the second light sensation value is smaller than the second preset threshold, the terminal may record the second light sensation value, and use the second light sensation value as the target light sensation value. For example, the second preset threshold is 20Lux, and when the second light sensitivity value acquired by the terminal is 16Lux, the terminal may record the second light sensitivity value (16Lux) as the target light sensitivity value.
In a possible implementation manner, the terminal may also detect a magnitude relationship between pixel values of a predetermined number of pixels in the display screen and the first preset threshold when detecting a magnitude relationship between the second light sensation value and the second preset threshold. Optionally, the terminal may acquire, through the image acquisition assembly, an image in the display screen of the terminal at the same time as the second light sensation value, acquire a pixel value of each pixel point in the image, compare the pixel value of each pixel point with a first preset threshold, and count a first number, where the first number is the number of pixel points whose pixel values are greater than the first preset threshold, and when the first number counted by the terminal is greater than the preset number, it may be determined that the pixel values of the pixel points of the preset number in the display screen are greater than the first preset threshold.
For example, the pixel value of each pixel of the display screen in the terminal is represented by an RGB (Red Green Blue ) color mode, and the first preset threshold may be 224. Then, after the terminal collects the image in the terminal display screen at the same time as the second light sensation value through the image collection assembly, the value of each pixel point is obtained and compared with 224, the number of the pixel points which are larger than 224 is counted, and then whether the number of the pixel points which are larger than 224 is larger than the preset number is judged, so that whether the pixel values of the pixel points with the preset number in the display screen are larger than a first preset threshold value is determined.
The first preset threshold, the second preset threshold and the preset number can be set in the terminal in advance by a developer or an operation and maintenance person.
Optionally, when the terminal determines that the pixel values of the preset number of pixel points in the display screen are greater than a first preset threshold and the target light sensation value is smaller than a second preset threshold, the terminal may determine that the terminal is currently in the target state.
Optionally, the terminal may further include a status flag bit, and the status flag bit indicates whether the terminal is in the target state. For example, when the terminal determines that the pixel values of the preset number of pixels in the display screen are greater than a first preset threshold and the target light sensation value is less than a second preset threshold, the terminal may write a first confirmation value in the status flag bit, where the first confirmation value may indicate that the terminal is in the target state, and if the terminal determines that the above condition is not satisfied, the terminal may also write a second confirmation value in the status flag bit, where the first confirmation value may indicate that the terminal is not in the target state.
Optionally, in this step, whether the detection terminal is in the target state may be detected by detecting a value of the status flag. That is, the terminal may acquire a value in the status flag, and detect whether the terminal is in the target state by detecting whether the value in the status flag is equal to the first confirmation value. Optionally, if the terminal is identified as being in the target state by 1, 0 indicates that the terminal is not in the target state. Then, if the value in the state flag acquired by the terminal is 1, it can be detected that the terminal is in the target state, and if the value in the state flag acquired by the terminal is 0, it can be detected that the terminal is not in the target state.
Note that, the recording of the second photosensitive value may be performed after the first confirmation value is written in the status flag bit in the terminal, which is not limited in the embodiment of the present application.
Optionally, when the terminal is in the target state, step 303 is executed, and when the terminal is not in the target state, step 306 is executed.
That is, after the terminal is in the target state, the terminal may acquire the target light sensation section from the target light sensation value when determining that the terminal is in the target state. Taking the target light sensation value as the second light sensation value as an example, after the terminal records the second light sensation value, the terminal may further obtain a second light sensation interval according to the second light sensation value, record the obtained second light sensation interval, and use the second light sensation interval as the target light sensation interval. In a possible implementation manner, a first correspondence table may be set in the terminal, where the first correspondence table includes a correspondence table between the light sensation value and the light sensation section.
| Light sensing value | Light-sensitive section |
| Light sensitivity value of one | Light sensing section one |
| Light sensitivity value two | Light sensing interval two |
| …… | …… |
TABLE 1
Optionally, after the terminal acquires the second light sensing section, the terminal may query the table 1 to acquire the light sensing section corresponding to the second light sensing section. For example, if the size of the second light sensing section is light sensing section two, the terminal can obtain the second light sensing section as light sensing section two through the table 1, so that the second light sensing section two is recorded in the terminal corresponding to the second light sensing value, and the second light sensing section is used as the target light sensing section.
In a possible implementation manner, the terminal may also calculate the second light sensation interval directly according to the second light sensation value. For example, the terminal may have a preset calculation rule, and the second light sensation section may be calculated by using the second light sensation value of 0.5 times as the lower limit of the second light sensation section and the second light sensation value of 1.5 times as the upper limit of the second light sensation section. For example, the second light sensation value acquired by the terminal is 14Lux, and the second light sensation interval obtained by the terminal through calculation may be 7 to 21 Lux.
Optionally, after acquiring the first light sensation value, the terminal may compare the first light sensation value with a previously recorded target light sensation interval, and determine a relationship between the first light sensation value and the target light sensation interval. When the first light sensation value is within the target light sensation interval, step 304 is executed.
In step 304, when the first light sensation value is within the target light sensation interval, a target light sensation value is obtained.
That is, when the terminal determines that the first light sensation value is in the target light sensation zone, the terminal may obtain the target light sensation value corresponding to the target light sensation zone recorded previously. For example, if the terminal records the target light sensation interval corresponding to the second light sensation value according to the implementation manner of table 1, and the terminal is in the target state at this time, and the currently recorded target light sensation interval is the second light sensation interval in table 1, then the target light sensation value acquired by the terminal at this time is also the second light sensation value.
In a possible implementation manner, when the first light sensation value is determined not to be within the target light sensation interval in step 303, the terminal may further detect whether the first light sensation value is smaller than a second preset threshold; when the first light sensation value is smaller than a second preset threshold value, acquiring a first light sensation interval according to the first light sensation value; the target light sensation value is replaced by the first light sensation value, and the target light sensation interval is replaced by the first light sensation interval.
For example, the target light sensation interval is 7 to 21Lux, and if the first light sensation value acquired by the terminal is 6Lux, the terminal may detect a magnitude relationship between the first light sensation value and the second preset threshold. If the second predetermined threshold is still 20Lux, the terminal determines that the first light sensation value is smaller than the second predetermined threshold, and the terminal can obtain the first light sensation interval according to the first light sensation value. And recording the first light sensation value as a target light sensation value, and recording the first light sensation interval as a target light sensation interval. Optionally, the obtaining manner of the first light sensing section may refer to the obtaining manner of the second light sensing section, and details are not repeated here.
It should be noted that, before the terminal records the first light sensation value and the first light sensation interval, it may also be determined whether the terminal is still in the target state, if the terminal is not in the target state, the terminal may not need to record the first light sensation value and the first light sensation interval, and if the terminal is in the target state, the terminal may record the first light sensation value and the first light sensation interval, which is not limited in the embodiment of the present application.
Optionally, when the first light sensitivity value is not smaller than the second preset threshold, a second confirmation value is written in the status flag bit. That is, if the terminal obtains the result that the first photosensitivity value is not less than the second preset threshold value when judging the first photosensitivity value and the second preset threshold value, the terminal may determine that the terminal is not in the target state at this time, and may write the second confirmation value in the state flag bit. Still taking the second preset threshold as 20Lux for example, if the first preset threshold is 30Lux, the terminal may write 0 in the status flag bit at this time, thereby indicating that the terminal is not in the target state.
And 305, adjusting the brightness of the display screen according to the target light sensation value.
Optionally, the terminal may replace the size of the first light sensation value acquired in step 301 with the size of the target light sensation value, and use the target light sensation value as the illumination intensity of the display screen received the ambient light acquired at the current time, so as to adjust the brightness of the display screen according to the target light sensation value. That is, if the target light sensation value is 14Lux, the target light sensation interval is 7 to 21Lux, and the first light sensation value is 8Lux, the terminal still adjusts the brightness of the display screen according to the light sensation value of 14Lux, and at this time, the terminal can keep the brightness of the display screen corresponding to the light sensation value of 14Lux unchanged.
In step 308, a second light sensing interval is obtained according to the first light sensing value.
In step 309, the first photosensitive section is recorded.
Optionally, the description of steps 306 to 309 can refer to the step executed when the first light sensation value is not within the target light sensation interval in step 304, and the description thereof is omitted here. The second light sensing section may be the same light sensing section as the first light sensing section.
It should be noted that, in the process of executing the above step 301 to step 309, the terminal may obtain, in real time, an image in the display screen through the image acquisition component under the condition of display by the display screen, and obtain a pixel value of each pixel point in the display screen; detecting whether the pixel values of a preset number of pixel points are larger than a first preset threshold value or not; and writing a second confirmation value into the state flag bit when the pixel values of the pixel points with the preset number are not greater than the first preset threshold value. That is, the terminal may determine in real time whether itself is in the target state, and if not, may write the second confirmation value in the status flag bit. The details of the implementation herein can refer to the related contents in step 302, and are not described herein again.
