Referring first to FIG. 1 , FIG. 1 is a schematic plan view of a display screen according to an embodiment of the present invention. The display screen 21 includes a display area 215 and a non-display area 216 . The display area 215 performs the display function of the display screen 21 for displaying information. The non-display area 216 does not display information. Display screen 21 may include a plurality of non-display areas 216 spaced apart from each other. For example, non-display areas 216 are provided at the top and bottom of the display screen 21, respectively. The non-display area 216 can be used to set functional components such as cameras, receivers, and fingerprint modules.

The ambient light sensor 213 is disposed in the display area 215 of the screen 21 , for example, as shown in FIG. 1 , two ambient light sensors are disposed in the upper left corner and the lower right corner of the display area 215 respectively.

In some embodiments, the display screen 21 may be a liquid crystal display (Liquid Crystal Display, LCD) or an organic light-emitting diode (Organic Light-Emitting Diode, OLED) type display screen.

2 is a schematic flowchart of an ambient light detection method provided by an embodiment of the present application. The method is applied to an electronic device, and the electronic device includes a plurality of ambient light sensors disposed at different positions in a screen display area. The ambient light detection includes the following step:

In step S101, the current brightness value of the screen area corresponding to each ambient light sensor is obtained respectively, so as to obtain a plurality of brightness values.

Among them, the above ambient light sensors may be two or more, etc., and are arranged scattered under the display area of the screen. For example, the electronic device includes four ambient light sensors, which are respectively arranged in the lower left corner, upper left corner, and upper right corner of the display area of the screen. corner and the lower right corner, the screen areas corresponding to the above four ambient light sensors respectively are the above four corners of the display area.

In one embodiment, the area of the screen area corresponding to the ambient light sensor may be 1cm×1cm, that is, 1cm ² . For example, in a display screen with a resolution of 1920×1080, the number of pixels in the image is 2,073,600, and the screen area corresponding to the ambient light sensor can be 100×50, that is, 5,000 pixels. area of pixels. The present invention does not further limit this.

Among them, before acquiring the current brightness value of the screen area corresponding to each ambient light sensor, it is also possible to determine whether the electronic device is in a bright screen state, and if so, acquire the image currently displayed on the screen, and then further acquire the ambient light in the image. The current brightness value of the image area corresponding to the sensor. Specifically, the screen is in the bright-screen state as the trigger condition, and by monitoring the process of the system application program, it is determined whether the screen of the electronic device is in the bright-screen state, and when the capacitive touch screen is monitored to be lit, it means that the screen is in Bright screen state, that is, to obtain the image currently displayed on the screen.

In one embodiment, the brightness value of each pixel in the screen area corresponding to the ambient light sensor can be obtained, specifically, the brightness value of each pixel can be extracted and stored in the form of a matrix, so that the brightness value can be directly called later. , and then calculate the average brightness value of the area. For example, add the obtained brightness value of each pixel point and divide it by the number of pixels to generate the current brightness value of the screen area corresponding to the ambient light sensor. Among them, in the acquired image of the screen area, the red component, green component and blue component (red, green, blue, RGB) of each pixel can be converted into hue, saturation and brightness values (Hue, saturation, RGB) , value, HSV) to get the brightness value of each pixel.

In the above embodiment, in the acquired image, the red component, the green component and the blue component of each pixel are acquired, and the RGB of each pixel is converted into HSV. The conversion of the RGB color space to the HSV color space is in the prior art, and details are not described here.

Step S102 , comparing a plurality of brightness values, and determining that the smallest brightness value is the target brightness value, and the ambient light sensor corresponding to the target brightness value is the target ambient light sensor.

After acquiring the brightness values of the screen areas corresponding to the multiple ambient light sensors, the aforementioned multiple brightness values are compared to determine the minimum target brightness value. In this embodiment of the present invention, the unit of the luminance value may be nits. For example, in one embodiment, the electronic device includes four ambient light sensors, which are respectively disposed at the upper left, lower left, upper right and lower right of the screen display area, and the brightness values of the above four screen areas measured in step S101 are 200nits, 500nits, 300nits and 350nits, you can determine the minimum brightness value of 200nits, that is, the target brightness value, and determine the ambient light sensor corresponding to the upper left position of the screen display area as the target ambient light sensor.

In one embodiment, if there is a screen area with the same brightness value and the minimum brightness among the current brightness values of the screen areas corresponding to the above-mentioned multiple ambient light sensors, any one of the screen areas with the same brightness can be designated. The corresponding ambient light sensor is the target ambient light sensor.

Step S103, acquiring the first light intensity value currently detected by the target ambient light sensor.

Ambient light sensors are mainly composed of photosensitive elements. At present, photosensitive components have developed rapidly, have a wide variety and are widely used. There are photoresistors, photodiodes, phototransistors, silicon photovoltaic cells, etc. on the market. The ambient light sensor can sense the surrounding light and tell the processing chip to automatically adjust the backlight brightness of the display to reduce the power consumption of the product. For example, in mobile phone, notebook, GPS and other mobile handheld device applications, the display consumes up to 30% of the total battery power, and the use of ambient light sensors can maximize the battery's working time. On the other hand, the ambient light sensor helps the display deliver a soft picture. When the ambient brightness is high, the LCD monitor using the ambient light sensor will automatically adjust to high brightness. When the external environment is dark, the display will be adjusted to low brightness.

In one embodiment, the light intensity values detected by the ambient light sensor for a preset number of times may be acquired, and then the average value of the plurality of light intensity values may be calculated, which is the first light intensity value. Among them, the preset number of times can be set according to the actual situation, such as 10 times, and the data is collected every 1 second to obtain the sampling data of the ambient light sensor in the electronic device for 10 consecutive times within 10 seconds. In the case of stability (such as indoor environment), the data beating is very small, basically beating in single digits, such as 501nits, 505nits, 503nits and other readings. After the above-mentioned multiple light intensity values are obtained, all the above-mentioned values may be added up, and then divided by the number to obtain the average light intensity value of the multiple light intensity values. For example, in a preset time period, the light intensity value of the ambient light sensor is sampled n times to obtain n light intensity values such as Q1, Q2, Q3...Qn, etc., calculate Q1+Q2+Q3+...+Qn and Divide the result by n to obtain its average light intensity value, which is the first light intensity value.

Step S104: Calculate the target light intensity value according to the first light intensity value and the target brightness value.

In the embodiment of the present invention, since the ambient light is disposed below the display area of the screen, the brightness of the screen will interfere with the measurement of the ambient light sensor. Specifically, the target light intensity value may be calculated by subtracting the target brightness value from the first light intensity value, where the target light intensity value is closer to the light intensity value of the current ambient light.

Wherein, the unit of the first light intensity value may be different from the unit of the target brightness value. For example, the unit of the first light intensity value may be Lux, and the unit of the target brightness value may be nits. Therefore, when calculating The above-mentioned units also need to be converted before, so that the unit of the first light intensity value is the same as the unit of the target brightness value, and now the calculation is performed.

After obtaining the target light intensity value, the electronic device can adjust the brightness of the display screen according to the ambient light intensity, so as to realize the automatic adjustment of the brightness.

It can be seen from the above that in this embodiment of the present application, the current brightness value of the screen area corresponding to each ambient light sensor can be obtained separately to obtain multiple brightness values, and the multiple brightness values can be compared to determine the minimum brightness value. , the ambient light sensor corresponding to the target brightness value is the target ambient light sensor, obtains the first light intensity value currently detected by the target ambient light sensor, and calculates the target light intensity value according to the first light intensity value and the target brightness value. In the present application, by setting multiple ambient light sensors in the terminal, and selecting the ambient light sensor with the smallest brightness corresponding to the screen area for light metering, the interference of the screen brightness on the detection result can be reduced, and the accuracy of ambient light detection can be improved.

According to the description of the previous embodiment, the ambient light detection method of the present application will be further described below.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart of another ambient light detection method provided by an embodiment of the present application, including the following steps:

Step S201, acquiring the brightness value of each pixel in the screen area corresponding to the ambient light sensor.

In one embodiment, the brightness value of each pixel can be extracted and stored in the form of a matrix, so that the brightness value can be directly called in the future, and then the average brightness value of the area can be calculated, such as the obtained value of each pixel. The brightness values are added and divided by the number of pixels to generate the current brightness value of the screen area corresponding to the ambient light sensor. Among them, in the acquired image of the screen area, the red component, green component and blue component (red, green, blue, RGB) of each pixel can be converted into hue, saturation and brightness values (Hue, saturation, RGB) , value, HSV) to get the brightness value of each pixel.

Step S202: Calculate the average brightness value according to the brightness value of each pixel point, and determine the average brightness value as the current brightness value of the screen area corresponding to the ambient light sensor, and obtain multiple brightness values to obtain multiple brightness values.

In one embodiment, before acquiring the brightness value of each pixel, it is also possible to determine whether the electronic device is in a bright screen state, and if so, acquire the image currently displayed on the screen, and then further acquire the corresponding ambient light sensor in the image. The luminance value of each pixel in the image area of . Specifically, the screen is in the bright-screen state as the trigger condition, and by monitoring the process of the system application program, it is determined whether the screen of the electronic device is in the bright-screen state, and when the capacitive touch screen is monitored to be lit, it means that the screen is in Bright screen state, that is, to obtain the image currently displayed on the screen

Step S203 , comparing a plurality of brightness values, and determining that the minimum brightness value is the target brightness value, and the ambient light sensor corresponding to the target brightness value is the target ambient light sensor.

In one embodiment, after acquiring the brightness values of the screen regions corresponding to the multiple ambient light sensors, the aforementioned multiple brightness values are compared to determine the smallest target brightness value among them. In this embodiment of the present invention, the unit of the luminance value may be nits. For example, in one embodiment, the electronic device includes four ambient light sensors, which are respectively disposed at the upper left, lower left, upper right and lower right of the screen display area, and the brightness values of the above four screen areas measured in step S101 are 200nits, 500nits, 300nits and 350nits, you can determine the minimum brightness value of 200nits, that is, the target brightness value, and determine the ambient light sensor corresponding to the upper left position of the screen display area as the target ambient light sensor.

Step S204, acquiring the first light intensity value currently detected by the target ambient light sensor.

In one embodiment, the light intensity values detected by the ambient light sensor for a preset number of times may be acquired, and then the average value of the plurality of light intensity values may be calculated, which is the first light intensity value. Among them, the preset number of times can be set according to the actual situation, such as 10 times, and the data is collected every 1 second to obtain the sampling data of the ambient light sensor in the electronic device for 10 consecutive times within 10 seconds. In the case of stability (such as indoor environment), the data beating is very small, basically beating in single digits, such as 501nits, 505nits, 503nits and other readings. After the above-mentioned multiple light intensity values are obtained, all the above-mentioned values may be added up, and then divided by the number to obtain the average light intensity value of the multiple light intensity values.

Step S205, acquiring the second light intensity value currently detected by ambient light sensors other than the target ambient light sensor.

Wherein, the second light intensity value currently detected by the ambient light sensor other than the target ambient light sensor may be the same as that in step S204.

Step S206, calculating the difference between the second light intensity value and the first light intensity value.

Step S207, it is judged whether the difference value is smaller than the preset value, if yes, then step S208 is executed, if not, the process ends.

In actual use, since the above-mentioned multiple ambient light sensors are all set in the display area of the screen, and the display area is also the touch area of the electronic device, when the user performs a touch operation on the electronic device, there may be user fingers or other If something is blocked above the ambient light sensor, the measured light intensity value is inaccurate. Therefore, it can be determined whether the target ambient light sensor is blocked. If it is not blocked, proceed to the next step.

The above determination of whether the target ambient light sensor is blocked can be determined by judging whether the difference between the first light intensity value measured by the above target sensor and the second light intensity value measured by other ambient light sensors is smaller than the preset value, because When one of the multiple ambient light sensors in the electronic device is blocked, the difference between the light intensity values measured by the ambient light sensor and other ambient light sensors will be relatively large. Therefore, this solution is used to determine whether the target ambient light sensor is blocked. . If the difference between the second light intensity value and the first light intensity value is smaller than the preset value, it is determined that the target ambient light sensor is not blocked, and step S208 is further performed.

Step S208: Calculate the difference between the first light intensity value and the target brightness value, and determine that the difference is the target light intensity value.

In the embodiment of the present invention, since the ambient light is disposed below the display area of the screen, the brightness of the screen will interfere with the measurement of the ambient light sensor. Specifically, the target light intensity value may be calculated by subtracting the target brightness value from the first light intensity value, where the target light intensity value is closer to the light intensity value of the current ambient light.

After obtaining the target light intensity value, the electronic device can adjust the brightness of the display screen according to the ambient light intensity, so as to realize the automatic adjustment of the brightness.

It can be seen from the above that the embodiment of the present application can obtain the brightness value of each pixel in the screen area corresponding to the ambient light sensor, calculate the average brightness value according to the brightness value of each pixel, and determine the average brightness value as the ambient light sensor. The current brightness value of the corresponding screen area is obtained multiple times to obtain multiple brightness values, and the multiple brightness values are compared to determine the minimum brightness value. The target brightness value, and the ambient light sensor corresponding to the target brightness value is the target ambient light The sensor obtains the first light intensity value currently detected by the target ambient light sensor, obtains the second light intensity value currently detected by the ambient light sensor other than the target ambient light sensor, and calculates the second light intensity value and the first light intensity value and determine whether the difference is smaller than the preset value, and if so, calculate the difference between the first light intensity value and the target brightness value, and determine that the difference is the target light intensity value. In the present application, by setting multiple ambient light sensors in the terminal, and selecting the ambient light sensor with the smallest brightness corresponding to the screen area for light metering, the interference of the screen brightness on the detection result can be reduced, and the accuracy of ambient light detection can be improved.
