[0002] In mobile devices or embedded systems, light sensors are used to detect ambient light intensity. Traditional technologies typically output only a single light intensity value, such as the LUX value. For example, in the MTK platform, the default SENSOR_TYPE_LIGHT only transmits one light sensor data, which cannot provide multi-channel light information related to color temperature, nor can it obtain ambient color temperature information. This limits its application in scenarios such as automatic color temperature adjustment, color reproduction, and eye protection mode. It also cannot distinguish different spectral components, such as R, G, and B components, resulting in poor device adaptability under complex lighting conditions. Furthermore, upper-layer applications cannot perform advanced image processing or environmental perception optimization based on multispectral data. Therefore, a new method for processing and transmitting light sensor color temperature data is urgently needed.

[0020] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for processing and transmitting color temperature data from a light sensor, as described in some embodiments of this application. This method is used in terminal devices, such as computers and mobile phones. The method includes the following steps: S11. Obtain light intensity recording data and real-time color temperature data through the SPC module, and perform preprocessing to obtain standard color temperature perception recording data; S12. The standard color temperature sensing and recording data is transmitted to the HAL module via the Kernel module; S13. Data reception and parsing are performed through the HAL module to obtain standard values ​​of light intensity and standard data of color temperature components. S14. Obtain the scene application feature data of the upper layer application, and analyze and process it in combination with the light intensity standard value and color temperature component standard data to obtain the corresponding scene adjustment strategy.

[0022] It should be noted that a mechanism for acquiring and transmitting R, G, and B three-channel color temperature data has been added to the light sensor data stream. Through the complete data transmission path from the SCP module to the HAL module, unified processing and reporting of multi-channel light sensing data can be achieved. Upper-layer applications can acquire color temperature data synchronously without changing the original light sensing monitoring interface, thereby improving environmental perception and adaptive capabilities.

[0023] According to an embodiment of the present invention, the step of acquiring light intensity recording data and real-time color temperature data through an SPC module, and performing preprocessing to obtain standard color temperature perception recording data includes: Light intensity recording data and real-time color temperature data are obtained through the SPC module. The real-time color temperature data includes R channel color temperature component data, G channel color temperature component data and B channel color temperature component data. The light intensity recording data, R-channel color temperature component data, G-channel color temperature component data, and B-channel color temperature component data are preprocessed by data verification and format conversion to obtain standard color temperature perception recording data.

[0024] It should be noted that the raw data is acquired through the transceiver unit of the SPC module, and then the data is verified and converted through the translate unit. The light intensity is unified to LUX units to resolve the differences in the raw outputs of different sensors, such as ADC values ​​and millilux. The R-channel color temperature component data, G-channel color temperature component data, and B-channel color temperature component data are converted into standard values ​​of 0-255 to resolve the differences in the raw outputs of different sensors, which are voltage values, percentages, or hexadecimal values, thereby obtaining standard color temperature sensing and recording data.

[0025] According to an embodiment of the present invention, the step of transmitting the standard color temperature sensing recording data to the HAL module via the Kernel module further includes: The first data check bit of the standard color temperature perception recording data is read through the Kernel module; If the verification fails, an early warning response will be output; If the verification is successful, the data sequence number of the standard color temperature perception record data is obtained and queried; If the data sequence number already exists, an early warning response is output; if the data sequence number does not exist, normal reception is performed, and the second data check bit is obtained through analysis. The first data check bit is compared with the second data check bit. If they are the same, the standard color temperature sensing record data is transmitted to the HAL module; otherwise, an early warning response is output.

[0026] It should be noted that, in order to ensure the accuracy and integrity of data transmission, before transmission after receiving, the first data check bit is obtained, which is a 16-bit digital fingerprint generated for the data by an algorithm, and is verified to ensure that the data has not been tampered with. After the verification is passed, the data sequence number is obtained to check whether it already exists, so as to avoid receiving the same data packet. The data sequence number is the sequence number added to each data during the standardization process. Before transmitting the data to the HAL module, the second data check bit of the data packet is recalculated and compared with the first data check bit to ensure that it has not been tampered with during storage.

[0027] According to an embodiment of the present invention, the step of receiving and parsing data through a HAL module to obtain standard values ​​of light intensity and standard data of color temperature components includes: The HAL module receives data and performs data separation and extraction processing to obtain standard values ​​of light intensity and standard data of color temperature components. The color temperature component standard data includes R channel color temperature component standard data, G channel color temperature component standard data and B channel color temperature component standard data.

[0028] It should be noted that the received data is analyzed to determine the light intensity and three-channel color temperature, and then encapsulated into a format that can be directly called by upper-layer applications.

[0029] According to an embodiment of the present invention, the step of obtaining scene application feature data of the upper-layer application and analyzing and processing it in conjunction with the light intensity standard value and color temperature component standard data to obtain the corresponding scene adjustment strategy includes: Obtain scenario application feature data from upper-layer applications, including automatic color temperature adjustment feature data or color reproduction feature data; The corresponding scene adjustment strategy is obtained by analyzing and processing the automatic color temperature adjustment feature data or color reproduction feature data in combination with the light intensity standard value and color temperature component standard data.

[0030] It should be noted that different scene adjustment strategies are matched for different application scenarios, and automatic color temperature adjustment feature data or color reproduction feature data are represented by different identifiers.

[0031] According to an embodiment of the present invention, the step of analyzing and processing the automatic color temperature adjustment feature data or color reproduction feature data in conjunction with the light intensity standard value and color temperature component standard data to obtain a corresponding scene adjustment strategy includes: If the data is for automatic color temperature adjustment, the standard data of the R channel color temperature component, the standard data of the G channel color temperature component, and the standard data of the B channel color temperature component are normalized and analyzed to obtain the absolute color temperature data of the environment. By mapping and analyzing the absolute color temperature data of the environment with the preset target color temperature data of the screen, an automatic color temperature adjustment strategy is obtained. If it is color reproduction feature data, then the standard data of the G channel color temperature component is compared with the standard data of the R channel color temperature component and the standard data of the B channel color temperature component to obtain the GR channel color temperature ratio and GB channel color temperature ratio. The color temperature ratios of the GR channel and GB channel are compared with preset channel color temperature thresholds, and a color reproduction adjustment strategy is obtained based on the threshold comparison results.

[0032] It should be noted that for automatic color temperature adjustment scenarios, firstly, the standard data of the R-channel, G-channel, and B-channel color temperature components are normalized. Then, based on the ratio of the R-channel to G-channel color temperature components and the ratio of the G-channel to B-channel color temperature components, threshold comparisons are performed to determine whether it is warm light, cool light, or neutral light. Finally, the absolute color temperature of the environment is determined using a preset RGB-to-color temperature formula. The preset RGB-to-color temperature formula for warm light is 2000 + (1 - r n The formula for converting RGB to color temperature for cool light presets is 5500 + b × 2500. n ×4500, the neutral light preset RGB to color temperature formula is 4500+[g n -(r n +b n [(2) / 2]×1000, r n b n g n These are the normalized values ​​for the standard data of the R channel color temperature component, the B channel color temperature component, and the G channel color temperature component, respectively. Table 1 shows an example of the mapping rules between ambient absolute color temperature data and preset screen target color temperature data. Table 1

[0033] This mapping rule example can be dynamically configured; For color reproduction scenarios, first, determine the color temperature ratios of the GR channel and GB channel. The GR channel color temperature ratio is the ratio of the standard data of the G channel color temperature component to the standard data of the R channel color temperature component, and the GB channel color temperature ratio is the ratio of the standard data of the G channel color temperature component to the standard data of the B channel color temperature component. Then, compare these ratios with the corresponding thresholds to determine the color reproduction adjustment strategy, i.e., perform white balance gain. For example, for ideal neutral white, R:G:B is 1:1:1. If the standard data of the R channel color temperature component is 200, the standard data of the G channel color temperature component is 180, and the standard data of the B channel color temperature component is 150, then the GR channel color temperature ratio is 0.9, the GB channel color temperature ratio is 1.2, the preset channel color temperature threshold is 1, and the corresponding color reproduction adjustment strategy is to increase the brightness of the B channel and decrease the brightness of the R channel.

[0041] It should be noted that the raw data is acquired through the transceiver unit of the SPC module, and then the data is verified and converted through the translate unit. The light intensity is unified to LUX units to resolve the differences in the raw outputs of different sensors, such as ADC values ​​and millilux. The R-channel color temperature component data, G-channel color temperature component data, and B-channel color temperature component data are converted into standard values ​​of 0-255 to resolve the differences in the raw outputs of different sensors, which are voltage values, percentages, or hexadecimal values, thereby obtaining standard color temperature sensing and recording data.

[0042] According to an embodiment of the present invention, the step of transmitting the standard color temperature sensing recording data to the HAL module via the Kernel module further includes: The first data check bit of the standard color temperature perception recording data is read through the Kernel module; If the verification fails, an early warning response will be output; If the verification is successful, the data sequence number of the standard color temperature perception record data is obtained and queried; If the data sequence number already exists, an early warning response is output; if the data sequence number does not exist, normal reception is performed, and the second data check bit is obtained through analysis. The first data check bit is compared with the second data check bit. If they are the same, the standard color temperature sensing record data is transmitted to the HAL module; otherwise, an early warning response is output.

[0043] It should be noted that, in order to ensure the accuracy and integrity of data transmission, before transmission after receiving, the first data check bit is obtained, which is a 16-bit digital fingerprint generated for the data by an algorithm, and is verified to ensure that the data has not been tampered with. After the verification is passed, the data sequence number is obtained to check whether it already exists, so as to avoid receiving the same data packet. The data sequence number is the sequence number added to each data during the standardization process. Before transmitting the data to the HAL module, the second data check bit of the data packet is recalculated and compared with the first data check bit to ensure that it has not been tampered with during storage.

[0044] According to an embodiment of the present invention, the step of receiving and parsing data through a HAL module to obtain standard values ​​of light intensity and standard data of color temperature components includes: The HAL module receives data and performs data separation and extraction processing to obtain standard values ​​of light intensity and standard data of color temperature components. The color temperature component standard data includes R channel color temperature component standard data, G channel color temperature component standard data and B channel color temperature component standard data.

[0045] It should be noted that the received data is analyzed to determine the light intensity and three-channel color temperature, and then encapsulated into a format that can be directly called by upper-layer applications.

[0046] According to an embodiment of the present invention, the step of obtaining scene application feature data of the upper-layer application and analyzing and processing it in conjunction with the light intensity standard value and color temperature component standard data to obtain the corresponding scene adjustment strategy includes: Obtain scenario application feature data from upper-layer applications, including automatic color temperature adjustment feature data or color reproduction feature data; The corresponding scene adjustment strategy is obtained by analyzing and processing the automatic color temperature adjustment feature data or color reproduction feature data in combination with the light intensity standard value and color temperature component standard data.

[0047] It should be noted that different scene adjustment strategies are matched for different application scenarios, and automatic color temperature adjustment feature data or color reproduction feature data are represented by different identifiers.

[0048] According to an embodiment of the present invention, the step of analyzing and processing the automatic color temperature adjustment feature data or color reproduction feature data in conjunction with the light intensity standard value and color temperature component standard data to obtain a corresponding scene adjustment strategy includes: If the data is for automatic color temperature adjustment, the standard data of the R channel color temperature component, the standard data of the G channel color temperature component, and the standard data of the B channel color temperature component are normalized and analyzed to obtain the absolute color temperature data of the environment. By mapping and analyzing the absolute color temperature data of the environment with the preset target color temperature data of the screen, an automatic color temperature adjustment strategy is obtained. If it is color reproduction feature data, then the standard data of the G channel color temperature component is compared with the standard data of the R channel color temperature component and the standard data of the B channel color temperature component to obtain the GR channel color temperature ratio and GB channel color temperature ratio. The color temperature ratios of the GR channel and GB channel are compared with preset channel color temperature thresholds, and a color reproduction adjustment strategy is obtained based on the threshold comparison results.

[0049] It should be noted that for automatic color temperature adjustment scenarios, firstly, the standard data of the R-channel, G-channel, and B-channel color temperature components are normalized. Then, based on the ratio of the R-channel to G-channel color temperature components and the ratio of the G-channel to B-channel color temperature components, threshold comparisons are performed to determine whether it is warm light, cool light, or neutral light. Finally, the absolute color temperature of the environment is determined using a preset RGB-to-color temperature formula. The preset RGB-to-color temperature formula for warm light is 2000 + (1 - r n The formula for converting RGB to color temperature for cool light presets is 5500 + b × 2500. n ×4500, the neutral light preset RGB to color temperature formula is 4500+[g n -(r n +b n [(2) / 2]×1000, r n b n g n These are the normalized values ​​of the standard data of the R channel color temperature component, the standard data of the B channel color temperature component, and the standard data of the G channel color temperature component, respectively. An example of the mapping rule between the ambient absolute color temperature data and the preset screen target color temperature data is shown in Table 1. This mapping rule example can be dynamically configured. For color reproduction scenarios, first, determine the color temperature ratios of the GR channel and GB channel. The GR channel color temperature ratio is the ratio of the standard data of the G channel color temperature component to the standard data of the R channel color temperature component, and the GB channel color temperature ratio is the ratio of the standard data of the G channel color temperature component to the standard data of the B channel color temperature component. Then, compare these ratios with the corresponding thresholds to determine the color reproduction adjustment strategy, i.e., perform white balance gain. For example, for ideal neutral white, R:G:B is 1:1:1. If the standard data of the R channel color temperature component is 200, the standard data of the G channel color temperature component is 180, and the standard data of the B channel color temperature component is 150, then the GR channel color temperature ratio is 0.9, the GB channel color temperature ratio is 1.2, the preset channel color temperature threshold is 1, and the corresponding color reproduction adjustment strategy is to increase the brightness of the B channel and decrease the brightness of the R channel.
