DETAILED DESCRIPTION

[0068] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with certain aspects of the present disclosure as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0069] Currently, ultraviolet rays from sunlight can penetrate the atmosphere and reach the Earth's surface. Long-term exposure to these rays can cause physical discomfort. With the development of electronic devices, their functionality is gradually increasing. Electronic devices can now detect the intensity of ultraviolet rays in their environment and alert users to take appropriate protective measures.

[0070] A related art method for ultraviolet light detection uses a UV camera to capture image information when a user requests UV intensity information. The UV intensity information is then determined and displayed based on the image information. While the UV intensity information can be determined from the image information captured by the UV camera, the UV camera consumes a lot of power, increasing the power consumption of the electronic device. Furthermore, due to its complex structure and design, the UV camera is expensive, increasing the cost of the electronic device.

[0071] To address the above technical issues, the present disclosure provides a method for detecting ultraviolet light using a light sensor in an electronic device, which detects ambient light information and determines ultraviolet intensity information based on the ambient light information. Because the power consumption of a light sensor is lower than that of a UV camera, detecting ultraviolet intensity using a light sensor reduces the power consumption of the electronic device. Furthermore, since the electronic device is equipped with a light sensor, there is no need to add an additional UV camera to detect ultraviolet intensity, thereby reducing the cost of the electronic device and the complexity of its structure.

[0072] For ease of understanding, the light sensor disclosed herein is first described. The light sensor has six ambient light sensing channels, namely, a red channel (Red channel), a green channel (Green channel), a blue channel (Blue channel), a transparent channel (Clear channel), a full spectrum channel (Wideband channel), and an infrared channel (IR channel). The channel values ​​of each channel reflect the intensity of red light, green light, blue light, transparent light, full spectrum light, and infrared light, respectively. Figure 1 As shown in the figure, different channels have different spectral responses, and the magnitude of the response can reflect the magnitude of the intensity. When the wavelength is between 300nm and 400nm, only the wideband channel responds. When the wavelength is greater than 400nm, all channels have corresponding responses, and the wideband channel always responds. Therefore, based on the channel values ​​of each channel, all light other than ultraviolet light can be eliminated to obtain ultraviolet intensity information. The horizontal axis λ represents the wavelength, and the vertical axis R represents the scaled and normalized response. Curve S1 represents the response curve corresponding to the Red channel, curve S2 represents the response curve corresponding to the Green channel, curve S3 represents the response curve corresponding to the Blue channel, curve S4 represents the response curve corresponding to the Clear channel, curve S5 represents the response curve corresponding to the Wideband channel, and curve S6 represents the response curve corresponding to the IR channel.

[0073] It is understandable that the light sensor may also include only five ambient light value channels, namely Red channel, Green channel, Blue channel, Clear channel and Wideband channel, and the infrared intensity can be calculated and determined based on the channel values ​​of the five channels.

[0074] The present disclosure provides a method for detecting ultraviolet rays. Figure 2 As shown, the method includes:

[0075] S200: Acquire ambient light information detected by a light sensor.

[0076] S300: Determine ultraviolet intensity information according to ambient light information and a preset relationship.

[0077] The preset relationship is used to characterize the relationship between ambient light and ultraviolet intensity.

[0078] In this embodiment, when it is necessary to detect the intensity of ultraviolet light in an environment, a light sensor detects and obtains ambient light information. Based on a preset relationship, the ultraviolet intensity information corresponding to the ambient light information is determined to achieve ultraviolet intensity detection. Because light sensors have low power consumption, using them to detect ultraviolet intensity reduces the power consumption of electronic devices. Furthermore, since all electronic devices are equipped with light sensors, ultraviolet intensity detection can be achieved without the need for additional components, thereby reducing the cost and structural complexity of the electronic devices.

[0079] Exemplarily, the ambient light information may include a red channel value, a green channel value, a blue channel value, a transparent channel value, a full-spectrum channel value, and / or an infrared coefficient. The red channel value may be the channel value of the Red channel, the green channel value may be the channel value of the Green channel, the blue channel value may be the channel value of the Blue channel, the transparent channel value may be the channel value of the Clear channel, the full-spectrum channel value may be the channel value of the Wideband channel, and the infrared coefficient may be the channel value of the IR channel. The channel value of each channel may be determined by reading the value of a specific address of the internal register in the light sensor. For example, the specific address may be 0x95 to 0xA0. The values ​​in every two addresses represent the channel value of a channel.

[0080] In one embodiment, if Figure 3 As shown, in step S300, the ultraviolet intensity information is determined according to the ambient light information and the preset relationship in the following manner:

[0081] S310: Determine the infrared coefficient.

[0082] S320: Determine ultraviolet intensity information according to ambient light information, infrared coefficients, and a preset relationship.

[0083] In this embodiment, because the wavelength ranges of both ultraviolet and infrared light often have large full-spectrum channel values ​​and small values ​​in other channels, it is necessary to distinguish between the two wavelength ranges to avoid affecting the determination of ultraviolet intensity information. Since the infrared coefficient is larger in the infrared wavelength range than in the ultraviolet wavelength range, ultraviolet intensity information is determined by determining and combining it with the infrared coefficient for differentiation. By incorporating the infrared coefficient, it is possible to distinguish between low-infrared and high-infrared environments and accurately determine ultraviolet intensity information, thereby improving the accuracy of ultraviolet intensity detection.

[0084] For example, in step S310, the infrared coefficient may be determined by directly using the channel value of the IR channel of the light sensor as the infrared coefficient. This reduces the complexity of ultraviolet intensity detection.

[0085] In one embodiment, the infrared coefficient determined in step S310 may also be determined in the following manner:

[0086] The infrared coefficient is determined according to the red channel value, the green channel value, the blue channel value and the transparent channel value.

[0087] In this embodiment, since using channel values ​​as infrared coefficients may result in large errors, determining the infrared coefficient based on the red channel value, green channel value, blue channel value and transparent channel value can improve the accuracy of the infrared coefficient, thereby improving the accuracy of ultraviolet intensity detection.

[0088] For example, the infrared coefficient is determined according to the red channel value, the green channel value, the blue channel value, and the transparent channel value in the above steps, and can be determined using the following formula:

[0089] IR=(R+G+BC) / (2*C).

[0090] Among them, IR represents the infrared coefficient, R represents the channel value of the Red channel, G represents the channel value of the Green channel, B represents the channel value of the Blue channel, and C represents the channel value of the Clear channel.

[0091] In one embodiment, the preset relationship includes a first preset relationship and a second preset relationship. The first preset relationship is used to represent the relationship between ambient light and ultraviolet intensity when the infrared coefficient is less than or equal to the preset coefficient. The second preset relationship is used to represent the relationship between ambient light and ultraviolet intensity when the infrared coefficient is greater than the preset coefficient. In step S320, the ultraviolet intensity information is determined based on the ambient light information, the infrared coefficient, and the preset relationship in the following manner:

[0092] When the infrared coefficient is less than or equal to the preset coefficient, the ultraviolet intensity information is determined according to the ambient light information and the first preset relationship.

[0093] When the infrared coefficient is greater than the preset coefficient, the ultraviolet intensity information is determined according to the ambient light information and the second preset relationship.

[0094] In this embodiment, since the infrared coefficient is used to distinguish between low-infrared and high-infrared environments, accurate UV intensity information can be determined by simply setting corresponding preset relationships for low-infrared and high-infrared environments. When the infrared coefficient is less than or equal to the preset coefficient, the environment is a low-infrared environment, and UV intensity information is determined based on ambient light information and a first preset relationship. When the infrared coefficient is greater than the preset coefficient, the environment is a high-infrared environment, and UV intensity information is determined based on ambient light information and a second preset relationship. By determining UV intensity information based on two different preset relationships when the infrared coefficients differ, the accuracy of UV intensity detection is improved and the complexity of determining UV intensity information is reduced.

[0095] For example, the preset coefficient may be in the range of 0.7 to 0.9, or may be 0.75, 0.8, 0.85, or the like.

[0096] In one embodiment, the ultraviolet intensity information is determined according to the ambient light information and the first preset relationship in the above step by:

[0097] Ultraviolet intensity information is determined according to the red channel value, the green channel value, the blue channel value, the transparent channel value, the full spectrum channel value, and a first preset relationship.

[0098] In the above step, the ultraviolet intensity information is determined according to the ambient light information and the second preset relationship in the following manner:

[0099] Ultraviolet intensity information is determined according to the red channel value, the green channel value, the blue channel value, the transparent channel value, the full spectrum channel value, and a second preset relationship.

[0100] In this embodiment, since the full-spectrum channel values ​​can reflect the intensities of various types of light, it is necessary to combine the red, green, blue, and transparent channel values ​​to eliminate all light other than ultraviolet light to determine ultraviolet intensity information. When the infrared coefficient is less than or equal to a preset coefficient, the ultraviolet intensity information is determined based on the red, green, blue, transparent, and full-spectrum channel values, and a first preset relationship. When the infrared coefficient is greater than the preset coefficient, the ultraviolet intensity information is determined based on the red, green, blue, transparent, and full-spectrum channel values, and a second preset relationship. By combining the channel values ​​and different preset relationships in different infrared environments, interfering light can be eliminated, thereby improving the accuracy of ultraviolet intensity information detection.

[0101] For example, the first preset relationship and the second preset relationship may be two different first preset formulas and second preset formulas. The first preset formula may be f high (C, R, G, B, W), the second preset formula can be f low (C, R, G, B, W). R represents the channel value of the Red channel, G represents the channel value of the Green channel, B represents the channel value of the Blue channel, C represents the channel value of the Clear channel, and W represents the channel value of the Wideband channel.

[0102] Illustratively, in the above steps, the ultraviolet intensity information is determined based on the red channel value, the green channel value, the blue channel value, the transparent channel value, the full-spectrum channel value, and the first preset relationship, and the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full-spectrum channel value can be substituted into the first preset formula to obtain the ultraviolet intensity information. In the above steps, the ultraviolet intensity information is determined based on the red channel value, the green channel value, the blue channel value, the transparent channel value, the full-spectrum channel value, and the second preset relationship, and the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full-spectrum channel value can be substituted into the second preset formula to obtain the ultraviolet intensity information.

[0103] It is understandable that the first preset relationship and the second preset relationship may be represented by not only formulas but also curves, tables, etc., which are not limited here.

[0104] For example, while determining the ultraviolet intensity information based on the ambient light information and the first preset relationship in the above steps, it is also possible to determine the ultraviolet intensity information by substituting only the full spectrum channel values ​​and one or more of the red channel value, green channel value, blue channel value, and transparent channel value into the first preset relationship. The first preset relationship is different when the number of channel values ​​is different. While determining the ultraviolet intensity information based on the ambient light information and the second preset relationship in the above steps, it is also possible to determine the ultraviolet intensity information by substituting only the full spectrum channel values ​​and one or more of the red channel value, green channel value, blue channel value, and transparent channel value into the second preset relationship. The second preset relationship is different when the number of channel values ​​is different.

[0105] For example, in step S320, ultraviolet intensity information is determined based on the ambient light information, the infrared coefficient, and the preset relationship. In addition to selecting different preset relationships based on the infrared coefficient as described above, the infrared coefficient can also be directly used as the independent variable in the preset relationship, with the infrared coefficient adjusting the ultraviolet intensity information within the preset relationship. In this case, the red channel value, green channel value, blue channel value, transparent channel value, full spectrum channel value, and infrared coefficient need to be substituted into the preset relationship to obtain the ultraviolet intensity information.

[0106] For example, in step S300, the ultraviolet intensity information is determined based on the ambient light information and the preset relationship, and the infrared coefficient may not be determined, and the ultraviolet intensity information is determined directly based on the red channel value, green channel value, blue channel value, transparent channel value and full spectrum channel value in the ambient light information.

[0107] In one embodiment, after determining the ultraviolet intensity information according to the ambient light information and the preset relationship in step S300, the ultraviolet detection method further includes:

[0108] Based on the UV intensity information, determine the UV level.

[0109] In this embodiment, after determining the UV intensity information, the user cannot determine the intensity of UV rays in the environment due to the lack of reference UV intensity information. Based on the UV intensity information, the UV level is determined, allowing the user to determine the intensity of UV rays in the environment. By converting the UV intensity information into a UV level, the user can clearly understand the intensity of UV rays in the environment and take protective measures, thereby improving the reliability of UV detection.

[0110] Illustratively, the step of determining the ultraviolet level according to the ultraviolet intensity information may be determined by looking up a table.

[0111] In one embodiment, the light sensor is an under-screen light sensor. Figure 4 As shown, after obtaining the ambient light information detected by the light sensor in step S200, the ultraviolet detection method further includes:

[0112] S210: Determine the luminous information of the screen.

[0113] S220: Adjust the ambient light information according to the luminous information.

[0114] In this embodiment, when the light sensor is an under-display light sensor, the screen's luminous information affects the ambient light information detected by the light sensor, necessitating adjustment of the ambient light information. Because different luminous information has different effects on ambient light information, the ambient light information is adjusted based on the luminous information to eliminate its influence. By adjusting the ambient light information based on the luminous information, the influence of the UV intensity information is avoided, thereby improving the accuracy of UV detection.

[0115] Exemplarily, the determination of the luminous information of the screen in step S210 may be determined according to the picture displayed on the screen.

[0116] Exemplarily, the adjustment of the ambient light information according to the luminous information in step S220 may be performed in combination with the position of the light sensor and according to the influence of the luminous information at the position of the light sensor.

[0117] Exemplarily, adjusting the ambient light information based on the luminous information in step S220 may include determining the impact of the luminous information on the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full-spectrum channel value, generating corresponding compensation information based on the generated impact, and adjusting the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full-spectrum channel value using the compensation information. That is, the channel values ​​of the red channel, the green channel, the blue channel, the clear channel, and the wideband channel are adjusted using the compensation values ​​of the compensation information.

[0118] For example, when the light sensor is disposed at an opening position of the screen or at a narrow slit position of the screen, since the ambient light information will not be affected by the luminous information of the screen, step S210 and step S220 may not be executed.

[0119] For example, when it is necessary to detect the ultraviolet intensity information, in response to the user's detection operation, the screen is controlled to be turned off or the area where the light sensor is located is controlled to be turned off. In this case, steps S210 and S220 may not be performed.

[0120] In one embodiment, if Figure 5 As shown, after obtaining the ambient light information detected by the light sensor in step S200, the ultraviolet detection method further includes:

[0121] S230: Determine the calibration coefficient.

[0122] S240: Calibrate the ambient light information according to the calibration coefficient.

[0123] In this embodiment, due to variations in the production of different light sensors and the subsequent assembly of the light sensors into electronic devices, these variations can affect the ambient light information detected by the light sensors. During the production process, the electronic devices test the light sensors and determine calibration coefficients based on the test results, which are stored in the electronic devices. After obtaining the ambient light information detected by the light sensors, the stored calibration coefficients are determined and used to calibrate the ambient light information to eliminate these variations. By calibrating the ambient light information using the calibration coefficients, the error in the ambient light information is reduced, thereby improving the accuracy of the UV intensity information detection.

[0124] For example, in step S240, the ambient light information is calibrated according to the calibration coefficients. For example, a calibration coefficient may be set for each channel of the light sensor, and the red channel value, green channel value, blue channel value, transparent channel value, and full-spectrum channel value are calibrated using the corresponding calibration coefficients. That is, the channel values ​​of the red channel, green channel, blue channel, clear channel, and wideband channel are calibrated using the respective calibration coefficients.

[0125] For example, after obtaining the ambient light information detected by the light sensor in step S200, ambient light intensity information and color temperature information may be determined based on the ambient light information. Furthermore, after determining the ultraviolet level, the ambient light intensity information, color temperature information, ultraviolet intensity information, and ultraviolet level may be uploaded so that corresponding devices can obtain and use the above information.

[0126] In one embodiment, if Figure 6 As shown, before obtaining the ambient light information detected by the light sensor in step S200, the ultraviolet detection method further includes:

[0127] S100: Acquire test ambient light information detected by a light sensor under different ambient lights.

[0128] S110: Acquire test ultraviolet intensity information corresponding to the test environment light information.

[0129] S120: Determine a preset relationship based on the test ambient light information and the test ultraviolet intensity information.

[0130] In this embodiment, before detecting UV intensity information, a preset relationship between ambient light and UV intensity needs to be determined. Under different ambient light conditions, test ambient light information detected by the light sensor and the corresponding test UV intensity information are obtained. Based on the test ambient light information and the test UV intensity information, a preset relationship is determined to detect the UV intensity information. By obtaining different information under different ambient light conditions to determine the preset relationship, the preset relationship can be applied to the detection of UV intensity information under different ambient light conditions, thereby improving the reliability of UV detection.

[0131] For example, the ambient light in step S100 can be light from a sunny outdoor day, a cloudy outdoor day, an outdoor nighttime scene, an indoor scene with the lights on, an indoor scene near a window, or a special light source. Special light sources may include light sources A and H. Acquiring test UV intensity information corresponding to the test ambient light information in step S110 can be performed using a UV detector. During the process of determining the preset relationship, the electronic device and the UV detector can be placed close together to improve the accuracy of the test UV intensity information.

[0132] In one embodiment, if Figure 7 As shown, in step S120, the preset relationship is determined according to the test ambient light information and the test ultraviolet intensity information in the following manner:

[0133] S121 , determining the test infrared coefficient corresponding to each test environment light information.

[0134] S122: Determine a first preset relationship based on the test ambient light information in which the test infrared coefficient is less than or equal to the preset coefficient and the corresponding test ultraviolet intensity information.

[0135] S123 . Determine a second preset relationship according to the test ambient light information in which the test infrared coefficient is greater than the preset coefficient and the corresponding test ultraviolet intensity information.

[0136] S124: Use the first preset relationship and the second preset relationship as preset relationships.

[0137] In this embodiment, since it is necessary to distinguish between low-infrared and high-infrared environments during the detection of ultraviolet intensity information, a test infrared coefficient corresponding to each test ambient light information is determined. Based on the test ambient light information with a test infrared coefficient less than or equal to a preset coefficient and the corresponding test ultraviolet intensity information, a first preset relationship is determined, such that the first preset relationship represents the relationship between ambient light and ultraviolet intensity in a low-infrared environment. Based on the test ambient light information with a test infrared coefficient greater than the preset coefficient and the corresponding test ultraviolet intensity information, a second preset relationship is determined, such that the second preset relationship represents the relationship between ambient light and ultraviolet intensity in a high-infrared environment. By determining corresponding preset relationships in environments with varying infrared intensities, the accuracy of ultraviolet intensity information detection is improved and the complexity of determining ultraviolet intensity information is reduced.

[0138] Exemplarily, in step S122, a first preset relationship is determined based on the test environment light information in which the test infrared coefficient is less than or equal to the preset coefficient and the corresponding test ultraviolet intensity information. The channel values ​​of the Red channel, Green channel, Blue channel, Clear channel and Wideband channel in the test environment light information in which the test infrared coefficient is less than or equal to the preset coefficient can be used as independent variables, and the corresponding test ultraviolet intensity information can be used as the dependent variable to generate the first preset formula by fitting.

[0139] Exemplarily, in step S123, the second preset relationship is determined based on the test environment light information in which the test infrared coefficient is greater than the preset coefficient and the corresponding test ultraviolet intensity information.

[0142] The present disclosure provides a method for detecting ultraviolet rays. Figure 8 As shown, the method includes:

[0143] S400: Obtain red channel values, green channel values, blue channel values, transparent channel values, and full-spectrum channel values ​​detected by the light sensor.

[0144] S410: Determine whether the light sensor is an under-screen light sensor.

[0145] S420: When the light sensor is an under-screen light sensor, determine the light emitting information of the screen.

[0146] S430 , adjusting the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full-spectrum channel value according to the luminescence information.

[0147] S440: Determine the calibration coefficient.

[0148] S450 , calibrating the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full spectrum channel value according to the calibration coefficient.

[0149] S460 , determining an infrared coefficient according to the red channel value, the green channel value, the blue channel value, and the transparent channel value.

[0150] S470: When the infrared coefficient is less than or equal to the preset coefficient, the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full spectrum channel value are substituted into a first preset formula to obtain ultraviolet intensity information.

[0151] S480: When the infrared coefficient is greater than the preset coefficient, the red channel value, the green channel value, the blue channel value, the transparent channel value, and the full spectrum channel value are substituted into a second preset formula to obtain ultraviolet intensity information.

[0152] S490: Determine the ultraviolet level according to the ultraviolet intensity information.

[0153] In this embodiment, when it is necessary to detect the intensity of ultraviolet light in the environment, the red, green, blue, transparent, and full-spectrum channel values ​​detected by the light sensor are obtained. A determination is made as to whether the light sensor is an under-screen light sensor to determine whether the screen's luminous information affects the ambient light information. If the light sensor is an under-screen light sensor, the red, green, blue, transparent, and full-spectrum channel values ​​are adjusted based on the screen's luminous information to eliminate the impact of the luminous information. A calibration coefficient is determined, and the red, green, blue, transparent, and full-spectrum channel values ​​are calibrated based on the calibration coefficient to eliminate the impact of device differences. After adjusting and calibrating the ambient light information, an infrared coefficient is determined based on the red, green, blue, and transparent channel values. Based on the magnitude of the infrared coefficient, a corresponding preset relationship is selected to determine the ultraviolet intensity information and the corresponding ultraviolet level. Because the light sensor has low power consumption, using the light sensor to detect ultraviolet intensity reduces the power consumption of the electronic device. At the same time, since electronic devices are all equipped with light sensors, the intensity of ultraviolet rays can be detected without adding additional devices, thereby reducing the cost of the electronic devices and the complexity of the electronic device structure.
