Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.

The related art will be described first.

The ambient light sensor can sense the light condition of the surrounding environment, including the intensity and chromaticity of the light. The environment light sensor is arranged in an intelligent terminal such as a mobile phone, and various intelligent response functions can be realized by detecting the change of the chromaticity and the intensity of the ambient light. For example, under different environments, the brightness of the display screen is automatically adjusted, and the effect of protecting the eyesight of a user can be achieved while reasonable power saving is achieved. For another example, under different light conditions, by sensing the color of the ambient light, better shooting effect can be realized. For another example, under certain conditions, intelligent invocation of some applications can be realized under the condition that the screen is not unlocked.

In the non-full screen age, the ambient light sensor may be disposed at the edge of the electronic device screen, as shown in fig. 1. Therefore, the screen can not be interfered by the light emission of the screen when receiving the information of the ambient light. Alternatively, the ambient light sensor may be located on the side of the electronic device, as shown in FIG. 2. However, considering that the bezel of the electronic device is mostly made of metal material, an opening design is generally required to place the ambient light sensor. Although the ambient light sensor may be minimized for aesthetic reasons, thereby reducing the dark edges around the screen or the openings at the sides of the electronic device, this ultimately leaves the electronic device with less than perfect appearance.

After the electronic equipment enters the full-screen era, with the popularity of full-screen, waterfall screen and even surrounding screen, the occupation ratio of the screen on the surface of the electronic equipment is larger and larger, and the competitiveness of the electronic equipment on the appearance is greatly enhanced by placing the ambient light sensor below the screen.

A structure in which the ambient light sensor is disposed under the screen may be as shown in fig. 3. The film layer that ambient light got into the sensor and passed through is from last to being down for apron layer 11, touch-control layer 12, polarizer layer 13, 1/4 lambda slide layer 14, OLED display layer 15, arrives on ambient light sensor 16 at last. Wherein each layer in the cover plate layer, the touch layer, the polarizer layer, the 1/4 lambda glass layer and the OLED display layer comprises 1-20 layers of complex structures, such as various organic layers, inorganic layers, OCA glue layers and the like. Therefore, after the ambient light is absorbed and reflected by the multiple layers, the intensity of the light actually reaching the ambient light sensor is greatly reduced. For example, the transmittance of the cover plate layer is 98%, the transmittance of the touch layer is 95%, the transmittance of the polarizer layer is 45%, the transmittance of the 1/4 λ glass layer is 95%, the transmittance of the OLED display layer is 20%, and the intensity of light actually reaching the ambient light sensor after passing through the layers is less than 8% of the ambient light. On the other hand, a part of the light emitted by the display screen is emitted downwards through the substrate of the OLED display layer and reaches the ambient light sensor, and another part of the light is reflected when the light is emitted upwards and reaches the ambient light sensor.

It can be seen that, in the related art, a large portion of the light received by the ambient light sensor disposed under the screen actually comes from the light emitted from the screen. That is, in the related art, the intensity of ambient light detected by the ambient light sensor disposed under the screen is actually composed of two parts, one part from the screen light emission and the other part from the ambient light. The light emitted by the screen not only forms a background on the light intensity, but also forms a background on the light chromaticity, so that when the ambient light is weak, or the screen light is strong, or a certain color of the ambient light is weak, a large background noise appears in the value detected by the ambient light sensor, that is, the accuracy of ambient light detection is low.

It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer.

Referring to fig. 4, fig. 4 is a schematic flowchart of an ambient light detection method according to an embodiment of the present application. The ambient light detection method may be applied to an electronic device, and the electronic device may at least include a first ambient light sensor and a second ambient light sensor, the first ambient light sensor and the second ambient light sensor are covered by a display screen, as shown in fig. 5, and each of the first ambient light sensor 17 and the second ambient light sensor 18 can detect the intensity of red light band, green light band and blue light band in the environment.

The flow of the ambient light detection method provided by the embodiment may include:

101. the method comprises the steps of obtaining first red light intensity, first green light intensity and first blue light intensity detected by a first ambient light sensor under the current environment.

102. And acquiring a second red light intensity, a second green light intensity and a second blue light intensity detected by a second ambient light sensor under the current environment.

The ambient light sensor can sense the light condition of the surrounding environment, including the intensity and chromaticity of the light. The environment light sensor is arranged in intelligent electronic equipment such as a mobile phone, and various intelligent response functions can be realized by detecting the change of the chromaticity and the intensity of the ambient light. For example, the electronic device may adjust the brightness of the display screen based on the ambient light intensity value detected by the ambient light sensor. When determining that the electronic equipment is in the strong light environment according to the ambient light intensity value detected by the ambient light sensor, the electronic equipment can brighten the brightness of the display screen. When the electronic equipment is determined to be in a weak environment according to the ambient light intensity value detected by the ambient light sensor, the brightness of the display screen can be dimmed by the electronic equipment, so that the eyesight of a user is protected. However, in the related art, the value detected by the ambient light sensor is easily affected by self-luminescence of the screen, i.e., the accuracy of the value detected by the ambient light sensor is low.

In this embodiment, for example, the electronic device may first obtain the red light intensity (for example, denoted as a first red light intensity), the green light intensity (for example, denoted as a first green light intensity), and the blue light intensity (for example, denoted as a first blue light intensity) detected by the first ambient light sensor in the current environment. And, the electronic device may first obtain the red light intensity (for example, recorded as the second red light intensity), the green light intensity (for example, recorded as the second green light intensity), and the blue light intensity (for example, recorded as the second blue light intensity) detected by the second ambient light sensor in the current environment.

It should be noted that, in the embodiment of the present application, the Red light intensity detected by the ambient light sensor is an intensity value of a Red light (Red) channel detected by the ambient light sensor. The Green light intensity detected by the ambient light sensor is the intensity value of the Green light (Green) channel detected by the ambient light sensor. The intensity of Blue light detected by the ambient light sensor is the intensity value of Blue light (Blue) channel detected by the ambient light sensor.

And, in the case where the screen is lit, the intensity of red light detected by the ambient light sensor includes the sum of the intensity of red light in the ambient light and the intensity of red light generated by the screen lighting. The intensity of the green light detected by the ambient light sensor includes the sum of the intensity of the green light in the ambient light and the intensity of the green light generated by the screen lighting. The intensity of blue light detected by the ambient light sensor includes the sum of the intensity of blue light in the ambient light and the intensity of blue light generated by screen illumination.

103. The method comprises the steps of obtaining screen light coefficients and environment light coefficients corresponding to all wave bands in red light wave bands, green light wave bands and blue light wave bands, wherein the screen light coefficients are light intensity ratios of corresponding wave bands detected by a first environment light sensor and a second environment light sensor when a screen is turned on and no external environment light exists in advance, and the environment light coefficients are light intensity ratios of corresponding wave bands detected by the first environment light sensor and the second environment light sensor when the screen is turned off and the external environment light exists in advance.

For example, the electronic device may further obtain a screen light coefficient and an ambient light coefficient corresponding to each of a red light band, a green light band, and a blue light band. The screen light coefficient is a light intensity ratio of corresponding wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in screen lighting in advance and has no external ambient light. The ambient light coefficient is a light intensity ratio of corresponding wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in the presence of external ambient light in advance and the screen is extinguished.

For example, the screen light coefficient and the ambient light coefficient corresponding to the red light band acquired by the electronic device may be recorded as a first screen light coefficient and a first ambient light coefficient, respectively. The first screen light coefficient is a light intensity ratio of red light wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in screen lightening in advance and has no external ambient light. The first ambient light coefficient is a light intensity ratio of red light wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in the presence of external ambient light in advance and the screen is turned off.

The screen light coefficient and the ambient light coefficient corresponding to the green light band acquired by the electronic device may be recorded as a second screen light coefficient and a second ambient light coefficient, respectively. The second screen light coefficient is a light intensity ratio of a green light waveband detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in screen lighting in advance and no external ambient light exists. The second ambient light coefficient is a light intensity ratio of a green light waveband detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in the presence of ambient light in advance and the screen is turned off.

The screen light coefficient and the ambient light coefficient corresponding to the blue light band acquired by the electronic device may be recorded as a third screen light coefficient and a third ambient light coefficient, respectively. The third screen light coefficient is a light intensity ratio of blue light wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic equipment is in screen lighting in advance and has no external ambient light. The third ambient light coefficient is a light intensity ratio of blue light wave bands detected by the first ambient light sensor and the second ambient light sensor when the electronic device is in the presence of external ambient light in advance and the screen is extinguished.

104. And acquiring a red light intensity component from ambient light under the current environment according to the first red light intensity, the second red light intensity, the screen light coefficient corresponding to the red light wave band and the ambient light coefficient.

For example, after obtaining the first red light intensity detected by the first ambient light sensor, the second red light intensity detected by the second ambient light sensor, and the first screen light coefficient and the first ambient light coefficient corresponding to the red light band, the electronic device may calculate the red light intensity component from the ambient light in the current environment according to the first red light intensity, the second red light intensity, the first screen light coefficient and the first ambient light coefficient corresponding to the red light band.

It should be noted that the red light intensity component from the ambient light in the current environment calculated in the process of 104 refers to the part of the red light intensity that is only affected by the pure ambient light after the influence of the screen light emission is removed.

105. And acquiring a green light intensity component from the ambient light under the current environment according to the first green light intensity, the second green light intensity, the screen light coefficient corresponding to the green light wave band and the ambient light coefficient.

For example, after obtaining the first green light intensity detected by the first ambient light sensor, the second green light intensity detected by the second ambient light sensor, and the second screen light coefficient and the second ambient light coefficient corresponding to the green light wavelength band, the electronic device may calculate the green light intensity component from the ambient light in the current environment according to the first green light intensity, the second screen light coefficient and the second ambient light coefficient corresponding to the green light wavelength band.

It should be noted that the green light intensity component from the ambient light in the current environment calculated in the flow of 105 means the green light intensity that is only affected by the pure ambient light after the influence of the screen light emission is removed.

106. And obtaining the blue light intensity component from the ambient light under the current environment according to the first blue light intensity, the second blue light intensity, the screen light coefficient corresponding to the blue light wave band and the ambient light coefficient.

For example, after obtaining the first blue light intensity detected by the first ambient light sensor, the second blue light intensity detected by the second ambient light sensor, and the third screen light coefficient and the third ambient light coefficient corresponding to the blue light wavelength band, the electronic device may calculate the blue light intensity component from the ambient light in the current environment according to the first blue light intensity, the second blue light intensity, the third screen light coefficient and the third ambient light coefficient corresponding to the blue light wavelength band.

It should be noted that the blue light intensity component from the ambient light in the current environment calculated in the process of 106 is the part of the blue light intensity that is only affected by the pure ambient light after the influence of the screen luminescence is removed.

107. And acquiring an ambient light intensity value and/or a color temperature value corresponding to the current environment according to the red light intensity component, the green light intensity component and the blue light intensity component.

For example, after the red light intensity component, the green light intensity component, and the blue light intensity component are obtained through calculation, the electronic device may calculate an ambient light intensity value and/or a color temperature value corresponding to the current environment according to the red light intensity component, the green light intensity component, and the blue light intensity component. That is, the electronic device may calculate the ambient light intensity value and/or the color temperature value according to the red light intensity, the green light intensity, and the blue light intensity that are only affected by the pure ambient light, and the finally calculated ambient light intensity value and/or color temperature value excludes the influence of the screen light on the ambient light intensity value and/or the color temperature value, and the intensity and the color temperature of the ambient light can be truly reflected, thereby improving the accuracy of the ambient light detection.

It is understood that in the embodiment of the present application, the electronic device may be configured with at least a first ambient light sensor and a second ambient light sensor, and the first ambient light sensor and the second ambient light sensor are capable of detecting intensities of red, green, and blue light bands in the environment. Based on this, the electronic device may obtain a first red light intensity, a first green light intensity, and a first blue light intensity detected by the first ambient light sensor in the current environment, and a second red light intensity, a second green light intensity, and a second blue light intensity detected by the second ambient light sensor. Moreover, the electronic device can acquire the screen light coefficient and the ambient light coefficient corresponding to each of the red light waveband, the green light waveband and the blue light waveband. Then, the electronic device may obtain a red light intensity component from ambient light in the current environment according to the first red light intensity, the second red light intensity, the screen light coefficient corresponding to the red light band, and the ambient light coefficient; acquiring a green light intensity component from ambient light under the current environment according to the first green light intensity, the second green light intensity, the screen light coefficient corresponding to the green light wave band and the ambient light coefficient; and acquiring a blue light intensity component from the ambient light under the current environment according to the first blue light intensity, the second blue light intensity, the screen light coefficient corresponding to the blue light wave band and the ambient light coefficient. Then, the electronic device may obtain an ambient light intensity value and/or a color temperature value corresponding to the current environment according to the red light intensity component, the green light intensity component, and the blue light intensity component. Because the electronic equipment can calculate the ambient light intensity value and/or the color temperature value according to the red light intensity, the green light intensity and the blue light intensity which are only influenced by pure ambient light, the finally calculated ambient light intensity value and/or the color temperature value exclude the influence of screen luminescence, and can truly reflect the intensity and the color temperature of the ambient light, thereby improving the accuracy of ambient light detection.

Referring to fig. 6, fig. 6 is another schematic flow chart of an ambient light detection method according to an embodiment of the present disclosure. The ambient light detection method can be applied to electronic equipment, the electronic equipment can at least comprise a first ambient light sensor and a second ambient light sensor, the first ambient light sensor and the second ambient light sensor are covered by a display screen, and each ambient light sensor can detect the light intensity of a red light waveband, a green light waveband, a blue light waveband, a visible light waveband and a full waveband in the environment.

The flow of the ambient light detection method provided by the embodiment of the application may include:

201. the light source type of the current environment is identified.

202. The method comprises the steps of obtaining screen light coefficients and environment light coefficients corresponding to all wave bands in red light wave bands, green light wave bands and blue light wave bands, wherein the environment light coefficients correspond to light source types, the screen light coefficients are light intensity ratios of corresponding wave bands detected by a first environment light sensor and a second environment light sensor when a screen is on and no external environment light exists in advance, and the environment light coefficients are light intensity ratios of corresponding wave bands detected by the first environment light sensor and the second environment light sensor when the screen is off and the external environment light exists in advance.

For example, 201, 202 may include:

the electronic device may first obtain the light source type of the current environment.

For example, common light sources include CWF (Cool White Fluorescent, American Cold White store light), U30 (Water White Fluorescent, American Warm White store light), TL84 (European, Japanese, Chinese store light), D65 (International Standard Artificial Daylight), A (American kitchen Window light), Hz light.

In the embodiment of the present application, 3 light sources, such as CWF, U30, TL84, can be classified into a first light source type, a D65 light source into a second light source type, an a light source into a third light source type, and an Hz light source into a fourth light source type.

In one embodiment, the electronic device may identify the light source type of the current environment by a ratio of W/C, where W is the light intensity of the full band of the ambient light and C is the light intensity of the visible band of light in the ambient light. Because the ambient light sensor in the embodiment of the application can detect the light intensities of the red light wave band, the green light wave band, the blue light wave band, the visible light wave band and the full wave band in the environment, the electronic device can firstly acquire the light intensity W of the full wave band of the environment and the light intensity C of the visible light wave band, and then identify the light source type of the current environment by calculating the ratio of W/C.

In some embodiments, when the ratio of W/C is in the numerical range of [0-0.7), it can be identified that the environment is the first light source type, i.e., CWF, U30 or TL 84. When the ratio of W/C is in the numerical range of [0.7, 1.1), it can be identified that the environment is the second light source type, i.e., D65. When the ratio of W/C is in the numerical range of [1.1-1.4), it can be identified that the environment is the third light source type, i.e., a. When the ratio of W/C is greater than 1.4, it can be identified that the environment is the fourth light source type, i.e., Hz.

For example, after identifying the light source type of the current environment, the electronic device may obtain a screen light coefficient and an ambient light coefficient corresponding to a red light band, a screen light coefficient and an ambient light coefficient corresponding to a green light band, and a screen light coefficient and an ambient light coefficient corresponding to a blue light band. Wherein, the ambient light coefficient of each wave band corresponds to the type of the light source. That is, each band corresponds to a different ambient light coefficient for different light source types. The screen light coefficient may be a light intensity ratio of corresponding bands detected by the first ambient light sensor and the second ambient light sensor when the electronic device is on the screen in advance and there is no ambient light. The ambient light coefficient may be a light intensity ratio of corresponding bands detected by the first ambient light sensor and the second ambient light sensor when the electronic device is in the presence of ambient light in advance and the screen is turned off.

The screen light coefficient corresponding to each band and the ambient light coefficient under each light source type can be measured in advance in the following modes:

for example, in the red light band, the luminance of the R pixel of the display panel may be adjusted to 255, and the luminances of the G pixel and the B pixel of the display panel may be adjusted to 0 (i.e., G, B pixels are not lit) in the environment without external ambient light, that is, the color (R, G, B) displayed on the display panel corresponds to (255, 0, 0). At the same time, a certain brightness, for example 155, can be input to the display screen. Of course, the brightness input to the display screen may be other values as long as the sensitivity requirement is not too weak. Then, the electronic device may collect the values detected by the first ambient light sensor and the second ambient light sensor, respectively, for example, the value detected by the first ambient light sensor is a1, and the value detected by the second ambient light sensor is b 1. It will be appreciated that a1 is actually the detected intensity of red light emitted by the display screen and b1 is actually the detected intensity of red light emitted by the display screen. Then, the screen light coefficient m1 corresponding to the red light band is a1/b 1.

In another embodiment, under the same test environment, the screen light coefficient corresponding to the red light band may also be a ratio of a mean value of a plurality of sets of values detected by the first ambient light sensor to a mean value of a plurality of sets of values detected by the second ambient light sensor.

The display may then be switched off, i.e. the display enters a switched-off state, and the external light source, e.g. the CWF light source at a brightness of 1000Lux, is switched on.

For example, the electronic device may further obtain a first red light intensity, a first green light intensity, and a first blue light intensity detected by a first ambient light sensor in the current environment, and a second red light intensity, a second green light intensity, and a second blue light intensity detected by a second ambient light sensor.

205. Calculating a red light intensity component R3 ═ m1 × R1-R2)/(m1-n1 from ambient light in the current environment, where R1 is a first red light intensity, R2 is a second red light intensity, m1 is a screen light coefficient corresponding to a red light band, and n1 is an ambient light coefficient corresponding to a red light band.

For example, after acquiring the first red light intensity R1, the second red light intensity R2, the screen light coefficient m1 corresponding to the red light band in the current environment, and the ambient light coefficient n1 in the current light source type, the electronic device may calculate the red light intensity component R3 only from the ambient light in the current environment, where R3 is (m1 × R1-R2)/(m1-n 1).

It should be noted that, in the ambient light intensity value R1 detected by the first ambient light sensor in the current environment, the light intensity from the screen light is assumed to be x1, and the light intensity from the ambient light is assumed to be y 1. Then x1+ y1 ═ R1. Based on the screen light coefficient m1 and the ambient light coefficient n1, the light intensity from the screen light emission in the ambient light intensity value R2 detected by the second ambient light sensor is m1 × x1, and the light intensity from the ambient light is n1 × y 1. Then m1 × x1+ n1 × y1 — R2. It is understood that x1+ y1 ═ R1 and m1 × x1+ n1 × y1 ═ R2 can form a system of linear equations in two dimensions, and by solving this system of linear equations in two dimensions, y1 ═ (m1 × R1-R2)/(m1-n1) can be obtained.

In the embodiment of the present application, the light intensity y1 of the red light band from the ambient light corresponding to the first ambient light sensor may be determined as the red light intensity component R3 from the ambient light in the current environment.

In another embodiment, the light intensity n1 × y1 of the red light band from the ambient light corresponding to the second ambient light sensor may also be determined as the red light intensity component from the ambient light in the current environment, where R4 ═ n1 × y1 ═ n1 × (m1 × R1-R2)/(m1-n1), where R1 is the first red light intensity, R2 is the second red light intensity, m1 is the screen light coefficient corresponding to the red light band, and n1 is the ambient light coefficient corresponding to the red light band.

It should be noted that, in the ambient light intensity value G1 detected by the first ambient light sensor in the current environment, the light intensity from the screen light is assumed to be x2, and the light intensity from the ambient light is assumed to be y 2. Then x2+ y2 is G1. Based on the screen light coefficient m2 and the ambient light coefficient n2, the light intensity from the screen light in the ambient light intensity value G2 detected by the second ambient light sensor is m2 × x2, and the light intensity from the ambient light is n2 × y 2. Then m1 × x2+ n1 × y2 — R2. It is understood that x2+ y2 ═ G1 and m2 × x2+ n2 × y2 ═ G2 can form a system of linear equations in two dimensions, and by solving this system of linear equations in two dimensions, y2 ═ (m2 × G1-G2)/(m2-n2) can be obtained.

For example, after acquiring the first blue light intensity B1, the second blue light intensity B2, the screen light coefficient m3 corresponding to the blue light band under the current environment, and the corresponding ambient light coefficient n3 of the blue light band under the current light source type, the electronic device may calculate the blue light intensity component B3 only from the ambient light under the current environment, where B3 is (m3 × B1-B2)/(m3-n 3).

It should be noted that, in the ambient light intensity value B1 detected by the first ambient light sensor in the current environment, the light intensity from the screen light is assumed to be x3, and the light intensity from the ambient light is assumed to be y 3. Then x3+ y3 is B1. Based on the screen light coefficient m3 and the ambient light coefficient n3, the light intensity from the screen light in the ambient light intensity value B2 detected by the second ambient light sensor is m3 × x3, and the light intensity from the ambient light is n3 × y 3. Then m3 × x3+ n3 × y3 is B2. It is understood that x3+ y3 ═ B1 and m3 × x3+ n3 × y3 ═ B2 can form a system of linear equations in two dimensions, and by solving this system of linear equations in two dimensions, y3 ═ (m3 × B1-B2)/(m3-n3) can be obtained.

In the embodiment of the present application, the light intensity y3 of the blue light band from the ambient light corresponding to the first ambient light sensor may be determined as the blue light intensity component B3 from the ambient light in the current environment.

That is, the electronic device may calculate the ambient light intensity value and/or the color temperature value from the red light intensity, the green light intensity, the blue light intensity, which are only affected by pure ambient light. Because the finally calculated ambient light intensity value and/or color temperature value excludes the influence of screen luminescence on the ambient light intensity value and/or color temperature value, the intensity and color temperature of the ambient light can be truly reflected, and the accuracy of ambient light detection is improved.

That is, in this embodiment, the electronic device may determine the ambient light intensity value and/or the color temperature value, which are only affected by the ambient light, corresponding to the first ambient light sensor as the ambient light intensity value and/or the color temperature value, which are only affected by the ambient light in the current environment.
