Referring to fig. 1, a flow of an embodiment of an ambient brightness value detection method according to the present disclosure is shown. The method for detecting the ambient brightness value as shown in fig. 1 includes the following steps:
In this embodiment, in response to determining that the terminal satisfies the preset condition, the electronic device executing the environment brightness value detection method may acquire the brightness value collected by the light-sensing sensor covered by the display screen of the terminal through the light-sensing area of the display screen. The display screen may be a display screen mounted on the terminal. In practical applications, the Display screen may be a Light Emitting Diode (LED) Display screen or a Liquid Crystal Display (LCD) Display screen. Optionally, the display screen may be an AMOLED (Active-matrix organic light-emitting diode) display screen.
The light sensing area may be an area preset in the display screen and used as a light sensor to sense light. In practice, the light-sensing area may be a smaller area. Alternatively, the light sensing area may be located at an upper end area of the display screen.
The light sensor may be covered by the display screen. In some application scenarios, the light-sensing area may completely cover the light-sensing sensor. The light sensing sensor may sense light transmitted from the light sensing area. Therefore, the light-sensing sensor detects the brightness value of the light passing through the light-sensing area.
It should be noted that the electronic device executing the ambient brightness value detection method and the terminal may be the same electronic device or different electronic devices. When the two are the same electronic device, the electronic device executing the environment brightness value detection method may detect the brightness value of the environment in which the display screen mounted thereon is located. When the two are not the same electronic device, the electronic device executing the environment brightness value detection method may detect the brightness value of the environment where the display screen installed in the terminal is located.
In some optional implementations, the preset condition may include at least one of: the display screen of the terminal is in a bright screen state; the terminal is in a preset display mode; the terminal currently runs a preset program; and the program currently operated by the terminal is in a preset mode. Here, the above-mentioned bright screen state may refer to a state in which the display screen is lit.
In these alternative implementations, the amount of computation of the electronic device executing the environment brightness value detection method is reduced by setting a limit condition for detecting the brightness value of the environment where the display screen is located.
And 102, acquiring the brightness value of the display screen and the target color displayed in the light sensing area.
In this embodiment, in response to determining that the terminal satisfies the preset condition, the electronic device executing the environment brightness value detection method may acquire the brightness value of the display screen and the target color displayed in the light sensing area on the display screen.
The target color may be the only color displayed in the light-sensing area, or may be one color selected from a plurality of colors displayed in the light-sensing area.
Specifically, the electronic device executing the environment brightness value detection method may obtain the brightness value of the display screen and the target color displayed in the light sensing area in real time through a built-in interface.
And 103, determining the interference value of the display screen to the light sensor according to the brightness value and the target color of the display screen.
In this embodiment, after obtaining the brightness value of the display screen and the target color displayed in the light sensing area, the electronic device executing the environment brightness value detection method may further determine the interference value of the display screen on the light sensing sensor according to the determined brightness value and the target color.
In practice, when the display screen is in a bright state, the light sensor can sense light rays of the environment where the display screen is located and light rays formed when the display screen is in the bright state. Therefore, the brightness value acquired by the light sensor not only includes the brightness value of the environment where the display screen is located, but also includes the brightness value of the light formed when the display screen is lighted. Here, the brightness value of the light formed when the display screen is in the lighting state is the interference value of the display screen on the light sensor.
In some application scenarios, the electronic device executing the ambient brightness value detection method has a corresponding relationship table built therein. In the corresponding relation table, the brightness value of the display screen and the displayed color correspond to one interference value. Therefore, the electronic device executing the ambient brightness value detection method can determine the interference value of the display screen to the light sensor by querying the corresponding relation table.
In other application scenarios, the electronic device executing the method for detecting the ambient brightness value may perform step 103 by using steps S1 to S3 similar to those described in the embodiment shown in fig. 3, and details thereof are not repeated here.
And step 104, taking the difference between the brightness value acquired by the light sensor and the interference value of the display screen to the light sensor as the brightness value of the detected environment where the display screen is located.
In this embodiment, after determining the interference value of the display screen to the photo sensor, the electronic device executing the method for detecting the brightness value of the environment may determine a difference between the brightness value collected by the photo sensor and the interference value of the display screen to the photo sensor, and use the obtained difference as the brightness value of the environment where the display screen is located.
In some alternative implementations, after step 104, the electronic device executing the environment brightness value detection method may adjust the brightness value of the display screen according to the brightness value of the environment where the display screen is located.
Specifically, the electronic device executing the ambient brightness value detection method has a correspondence relationship between the ambient brightness value and the display screen brightness value built in advance. Therefore, the electronic device executing the environment brightness value detection method can determine the brightness value of the display screen corresponding to the brightness value of the environment where the display screen is located by querying the corresponding relationship, and adjust the brightness value of the display screen to the queried brightness value.
In these optional implementations, the brightness value of the display screen is adjusted by taking the brightness value of the environment where the display screen is located into consideration, so that the brightness value of the display screen can be accurately adjusted.
Referring to fig. 2, an application scenario of the ambient brightness value detection method according to the embodiment of the present disclosure is shown. As shown in fig. 2, the electronic device 201 detects the brightness value of the environment in which the display screen mounted thereon is located, according to the steps shown below. First, in response to determining that a preset condition is satisfied, the electronic apparatus 201 may acquire the brightness value 202 collected by the light-sensing sensor covered by the display screen mounted thereon through the light-sensing area on the display screen. Then, the electronic device 201 may obtain the brightness value 203 of the display screen and the target color 204 displayed in the light sensing area. Then, the electronic device 201 can determine a disturbance value 205 of the display screen to the light sensor according to the brightness value 203 and the target color 204. Further, the electronic device 201 may use the difference between the brightness value 202 and the interference value 205 as the brightness value 206 of the detected environment in which the display screen is located.
At present, when detecting the brightness value of the environment where the display screen of the electronic device is located, one of the related methods is to store a large number of color features (e.g., color histograms) and interference values corresponding to each color feature in advance, and use the color features extracted from the light sensing area to match with the large number of color features stored in advance to determine the interference values of the display screen to the light sensing sensor, thereby detecting the brightness value of the environment where the display screen is located. In this embodiment, the interference value of the display screen to the light-sensing sensor is determined according to the brightness value of the display screen and the target color displayed in the light-sensing area, so as to further realize the detection of the brightness value of the environment where the display screen is located. Because a large number of color characteristics and interference values corresponding to each color characteristic do not need to be stored in advance, the occupation of the storage space of the electronic equipment is reduced.
With continued reference to fig. 3, a flow chart of yet another embodiment of the ambient brightness value detection method according to the present disclosure is shown. As shown in fig. 3, the method for detecting an ambient brightness value includes the following steps:
step 301, in response to determining that the terminal meets the preset condition, obtaining a brightness value acquired by a light sensing sensor covered by a display screen of the terminal through a light sensing area on the display screen.
Step 302, obtaining the brightness value of the display screen and the target color displayed in the light sensing area.
Step 301 and step 302 may be performed in a similar manner as step 101 and step 102 in the embodiment shown in fig. 1, and the above description for step 101 and step 102 also applies to step 301 and step 302, which is not described herein again.
In step 303, the interference value of each of the three primary colors on the light sensor at the luminance value of the display screen is determined.
In this embodiment, after acquiring the luminance value of the display screen and the target color displayed in the light sensing area, the electronic device executing the ambient luminance value detection method may determine the interference value of each of the three primary colors with the light sensing sensor at the luminance value of the display screen.
The three primary colors may be basic colors combined into any one of the colors displayed by the display screen. For example, the three primary colors may include pure red, pure green, and pure blue. Here, RGB (Red, Green, Blue) color values of pure Red, pure Green, and pure Blue may be (255,0,0), (0,255,0), and (0, 255), respectively.
Specifically, the electronic device that executes the ambient brightness value detection method has a relational expression for determining the interference value of each of the three primary colors with respect to the photosensor in advance built therein. Here, the relationship corresponding to each of the three primary colors corresponds to one interference value at each luminance value. Therefore, the electronic device executing the environment brightness value detection method can input the brightness value of the display screen into the relational expression corresponding to each of the three primary colors, and obtain the interference value of each of the three primary colors on the light sensor under the brightness value of the display screen.
And step 304, determining the interference value of the display screen to the light sensor according to the interference value of each of the three primary colors to the light sensor.
In this embodiment, the execution subject of the ambient brightness value detection method may determine the interference value of the display screen with respect to the light sensor according to the interference value of each of the three primary colors with respect to the light sensor.
Specifically, for the interference value of each of the three primary colors to the light sensor, the execution subject of the ambient brightness value detection method may select a maximum interference value as the interference value of the display screen to the light sensor.
In some alternative implementations, the electronic device executing the ambient brightness value detection method may perform step 304 in the manner shown in steps S1 through S3.
Step S1, determining a weight corresponding to the interference value of each of the three primary colors to the light sensor according to the color value corresponding to the target color.
The color values may be RGB color values of the target color.
The above-mentioned weights can be used to characterize the interference weight of each of the three primary colors on the photosensor.
Specifically, the electronic device that executes the ambient brightness value detection method for each of the three primary colors has a relational expression built in advance for determining a weight corresponding to an interference value of the color with respect to the photosensor. Here, each of the three primary colors corresponds to a relational expression in which the RGB components of the color correspond to a weight at each value. For example, the RGB component of pure red is R, and accordingly, the component R corresponds to a weight under each value. Therefore, for each of the three primary colors, the electronic device executing the ambient brightness value detection method may input the RGB component values of the color to the relational expression corresponding to the color, and obtain the weight corresponding to the interference value of the color on the light sensor.
In step S2, for each of the three primary colors, the product of the interference value and the corresponding weight of the color on the photo sensor is determined.
And step S3, determining the sum of the obtained products as the interference value of the display screen to the light-sensitive sensor. In these alternative implementations, any one of the colors displayed by the display screen can be obtained by superimposing the three primary colors. Accordingly, the interference value of the display screen to the light sensor can be obtained by superposing the interference values of the three primary colors to the display screen. Therefore, the interference values of the three primary colors to the light sensor are superposed through the corresponding weights, so that the interference values of the three primary colors to the light sensor can be effectively superposed, and the accuracy of determining the interference values of the display screen to the light sensor is further improved.
Step 305, determining the difference between the brightness value acquired by the light sensor and the interference value of the display screen on the light sensor as the brightness value of the detected environment where the display screen is located.
The above steps 305 may be performed in a similar manner as the steps 104 in the embodiment shown in fig. 1, and the above description for the steps 104 also applies to the steps 305, which is not described herein again.
In this embodiment, the interference value of the target color on the photo sensor is refined into the interference value of each of the three primary colors on the photo sensor, so as to improve the accuracy of determining the interference value of the display screen on the photo sensor, and further improve the accuracy of detecting the brightness value of the environment where the display screen is located.
