Description

Technical Field

[0001] The present disclosure relates to the field of data processing, and in particular, to a data processing method, apparatus, electronic device, and storage medium. Background Art

[0002] Currently, common optical sensors on the market have different functions, and different functions have different requirements for the acquisition frequency of the optical sensors, and the corresponding integration time of the optical sensors will also be different. For example, an optical sensor can be used for stroboscopic detection and ambient light detection. Stroboscopic detection has high requirements for the acquisition frequency of the optical sensor. In the case of a high acquisition frequency, the integration time of the optical sensor needs to be short enough. Therefore, when performing stroboscopic detection, the integration time of the optical sensor needs to be set to a short integration time. Ambient light detection requires a long integration time, and sufficient photosensitive information can be obtained only with a long integration time to ensure the accuracy of ambient light calculation.

[0003] Therefore, if different functions are to be achieved simultaneously, the integration time of the optical sensor needs to be switched, and switching the integration time requires frequently writing to the integration time register. Frequent writing to the register may result in write failures and unknown hardware problems, causing abnormal detection of the optical sensor. Summary of the Invention

[0069] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying 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. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0070] In the specification, unless otherwise clearly stated, the terms "first" and "second" are only used for description to distinguish constituent elements and should not be construed as indicating an order. Unless otherwise clearly stated, terms such as "connected" and "fixed" should be understood in a broad sense, including but not limited to "connected" and "fixed" directly, indirectly, detachably, etc.

[0071] Figure 1 is a process of a data processing method shown according to an exemplary embodiment Figure 1 , as Figure 1 shown, the method mainly includes the following steps:

[0072] In step 101, when both the first function and the second function of the electronic device are in the on state, determine the first integration time corresponding to the first function and the second integration time corresponding to the second function; wherein, the first integration time is less than the second integration time.

[0073] It should be noted that this method can be applied to an electronic device. The electronic device may include a terminal device. Among them, the terminal device may include a mobile terminal and a fixed terminal. For example, a mobile phone, a tablet computer, a personal digital assistant, a laptop computer, a desktop computer, a wearable device, and a vehicle-mounted terminal, etc.

[0074] In this embodiment, the first function and the second function are functions that the electronic device and the optical sensor of the electronic device can cooperate to complete. The optical sensor is a type of sensor that uses the optical principle to detect and measure the properties or change states of the target object. That is, the first function and the second function are detection or measurement functions completed by the electronic device based on the sensing data of the optical sensor for corresponding data processing. For example: stroboscopic detection function, ambient light detection function, object distance detection function, object movement speed detection function, and so on.

[0075] Among them, the integration time of the optical sensor refers to the time when the electrical signal is accumulated after receiving an optical signal, that is, the integration time determines the length of time for the optical sensor to collect the optical signal. It can be understood that optical signals often have fluctuations and noises. A shorter integration time corresponds to a higher sampling frequency, which can improve the response speed and sensitivity, but may introduce larger noises for the detection of weak optical signals. A longer integration time can improve the stability and accuracy of signal detection, but will increase the response time and reduce the sensitivity.

[0076] Therefore, different detection requirements for different functions correspond to different integration times. When both the first function and the second function of the electronic device are in the on state, it means that the electronic device expects to cooperate with the optical sensor to complete the first function and the second function in parallel.

[0077] In the related art, the purpose of completing the first function and the second function in parallel can be achieved by frequently switching the integration time of the optical sensor, but this method will not only cause a time break in the sensing data, but also cause hardware problems due to frequent switching of the integration time. Or by adding an optical sensor to achieve the purpose of completing the first function and the second function in parallel, but this method will increase the hardware cost and is not conducive to the miniaturization and integration of the electronic device.

[0078] For the first integration time corresponding to the first function and the second integration time corresponding to the second function, they can be determined according to the detection requirements of the first function and the second function. If the detection requirements require accuracy and precision, the integration time can be set to a longer integration time. If the detection requirements require a quick response to each optical signal and giving a result, the integration time can be set to a shorter integration time. Of course, in addition to considering the detection requirements of the function itself, the integration time corresponding to different functions can also be determined based on the detection performance of the optical sensor itself and the data processing ability of the electronic device.

[0079] In step 102, the optical sensor of the electronic device collects sensing data at the acquisition frequency determined based on the first integration time, obtains a plurality of first sensing data, and performs processing corresponding to the first function on the first sensing data to obtain a first processing result.

[0080] In this embodiment, the integration time of the optical sensor of the electronic device is set to a smaller first integration time, so that the optical sensor collects sensing data at the acquisition frequency determined by the first integration time, obtains a plurality of first sensing data. Then, after performing data processing corresponding to the first function on the first sensing data, the first processing result of the first function can be obtained.

[0081] Among them, the first integration time and the acquisition frequency are reciprocal to each other. Once the first integration time is determined, the optical sensor can collect a plurality of first sensing data at the corresponding acquisition frequency. For example: if the first integration time is 500 microseconds (μs), the acquisition frequency determined based on the first integration time is 2000 hertz (hz), which is equivalent to collecting once every 500 μs and collecting 2000 first sensing data in one second. The obtained plurality of first sensing data can be stored in the data register corresponding to the optical sensor for the processor to quickly access, or can be stored in the memory for storing a large amount of sensing data.

[0082] For the collected first sensing data, the electronic device can immediately perform processing corresponding to the first function on the first sensing data to obtain a first processing result, or can perform processing on the first sensing data when a calculation instruction related to the first function is detected to obtain a first processing result.

[0083] If the first function is an ambient light detection function, the type of the first sensing data, that is, the type of the electrical signal, is determined based on the type of the optical sensor (such as: photoresistor, photodiode, photodetector). Based on the conversion formula between the electrical signal (such as: resistance value, current value, voltage value) and the light intensity, the plurality of first sensing data are respectively substituted into the conversion formula between the electrical signal and the light intensity to obtain the ambient light intensity values at different times.

[0084] If the first function is the object distance detection function, the first sensing data is the transmission time from emitting the optical signal to receiving the optical signal. Based on the transmission time of the optical signal and the speed of light, the distance between the object and the optical sensor can be determined. Different functions correspond to different processing procedures. Of course, to improve the detection accuracy and precision, multiple first sensing data can be corrected, data with large differences from other sensing data can be screened out, and multiple preliminary results calculated can be averaged to obtain the final first processing result.

[0085] In step 103, based on the first sensing data corresponding to the second integration time, second sensing data is obtained, and the second sensing data is processed corresponding to the second function to obtain the second processing result.

[0086] In this embodiment, the first sensing data corresponding to the second integration time is determined from multiple first sensing data, and this is used as the second sensing data required for the second function. The second sensing data is processed with data processing corresponding to the second function to obtain the second processing result.

[0087] During the process of determining the second sensing data, it can start from any one of the first sensing data to determine the first sensing data corresponding to the second integration time, and at least one second sensing data is obtained. The number of determined second sensing data can be determined based on the detection requirements of the second function. If a processing result needs to be obtained quickly, a small number of second sensing data can be determined, and the small number of second sensing data can be processed to quickly obtain the processing result. If the accuracy of the processing result needs to be ensured, a large number of second sensing data can be determined, and mutual verification based on the large number of second sensing data can ensure the accuracy of the processing result.

[0088] For example: The first integration time is 500 μs, that is, the first sensing data is collected every 500 μs. If 100 pieces of first sensing data are collected, these 100 data are consecutive in time. Then, starting from the first piece of first sensing data, 40 pieces of first sensing data corresponding to the second integration time of 20 ms can be selected, that is, based on the 1st - 40th pieces of first sensing data, the first piece of second sensing data is obtained. Then, starting from the second piece of first sensing data, 40 pieces of first sensing data are selected, that is, based on the 2nd - 41st pieces of first sensing data, the second piece of second sensing data is obtained, and so on. 61 different second sensing data can be obtained.

[0089] Of course, based on the time when the detection object corresponding to the second function changes, the first sensing data corresponding to the second integration time can also be selected near this time to obtain the second sensing data. This can avoid the storage and processing of useless data and redundant data and improve the processing speed.

[0090] The present disclosure selects the smaller integration time from the first integration time corresponding to the first function and the second integration time corresponding to the second function, so that the optical sensor of the electronic device obtains a plurality of first sensing data according to the acquisition frequency determined by the smaller first integration time. In this way, the second sensing data can be directly determined based on the first sensing data corresponding to the second integration time, without switching the integration time to obtain the sensing data corresponding to different integration times simultaneously, achieving the parallel processing of multiple functions without changing the hardware and without interruption in data time.

[0091] In some embodiments, as Figure 2 shown, step 103 includes:

[0092] In step 1031, based on the first integration time and the second integration time, determine the equivalent number of the first sensing data corresponding to the second integration time;

[0093] In step 1032, group the plurality of first sensing data with the equivalent number of first sensing data that are continuous in time as a group to obtain a plurality of data groups; where each second integration time corresponds to one data group;

[0094] In step 1033, add up the first sensing data in each data group respectively to obtain the second sensing data corresponding to each second integration time, and perform processing corresponding to the second function on the second sensing data to obtain a second processing result.

[0095] In this embodiment, since the first integration time is less than the second integration time, the equivalent number of the first sensing data collected based on the acquisition frequency corresponding to the first integration time under the second integration time can be determined. That is, divide the second integration time by the first integration time to obtain the equivalent number.

[0096] For example: the first integration time is 500 μs, and the second integration time is 20 ms, then the equivalent number of the first sensing data collected every 500 μs under the 20 ms integration time is 40. Then, group the plurality of first sensing data with 40 consecutive first sensing data in terms of acquisition time as a group to obtain a plurality of data groups. The number of these data groups is equivalent to the number of the second sensing data collected every 20 ms. Finally, add up the first sensing data in each data group, and the sum value obtained by adding up each data group is the second sensing data. As Figure 3 shown, it is a data flow schematic diagram when the electronic device processes the first function and the second function simultaneously, where 500 μs is the first integration time and 20 ms is the second integration time.

[0097] It can be understood that the integration time of the optical sensor determines the length of time for collecting the optical signal. If the first integration time is 500 μs, it is equivalent to the collection time of the optical signal being 500 μs. If the second integration time is 20 ms, it is equivalent to the collection time of the optical signal being 20 ms. Then, by accumulating the first sensing data collected in 40 consecutive 500-μs intervals in time, the optical signal collected within 20 ms can be obtained. In this way, the sensing data collected by an optical sensor without switching the integration time can be used to complete the calculation and processing of multiple functions, which not only avoids modifying the hardware but also ensures the continuity of the data in time.

[0098] When obtaining the second sensing data, perform processing corresponding to the second function on the second sensing data. Taking the second function as the stroboscopic detection function as an example, since the stroboscopic detection function requires obtaining parameters such as the frequency of light flicker, the intensity of light flicker, and the change amplitude of light intensity through frequency-domain analysis, it is necessary to perform a Fourier transform on the second sensing data to obtain a spectrogram, determine the light flicker frequency based on the spectrogram, determine the light flicker intensity based on the peak value of the spectrogram, and determine the change amplitude of light intensity based on the difference between the peak value and the trough value of the spectrogram. In addition, during the process of performing a Fourier transform on the second sensing data, correction processing can also be performed on the second sensing data, and denoising filtering processing can be performed on the spectrogram to improve the accuracy of the second processing result.

[0099] In an embodiment, perform processing corresponding to the first function on the first sensing data to obtain a first processing result, including: sequentially storing each collected first sensing data into a preset first-in-first-out queue; when the number of first sensing data in the first-in-first-out queue reaches a first quantity, read the first quantity of first sensing data from the first-in-first-out queue, and perform processing corresponding to the first function on the first quantity of first sensing data to obtain a first processing result.

[0100] In this embodiment, since the first sensing data is obtained by the optical sensor according to the acquisition frequency corresponding to the first integration time, and the first integration time is a relatively short integration time, that is, the first sensing data is obtained at a relatively high acquisition frequency. Then, when the electronic device processes the first sensing data, it is very difficult to read and process the data at such a high acquisition frequency. For example, when the first integration time is 500 μs, it is equivalent to the optical sensor collecting the first sensing data every 500 μs, and the electronic device needs to read the first sensing data every 500 μs, which extremely tests the performance of the processor and memory of the electronic device. Reading data at such a high frequency will also generate extremely high power consumption.

[0101] Therefore, for each first sensing data collected by the optical sensor, it is sequentially stored in a first-in-first-out (FIFO) queue according to the collection time sequence. When the number of the first sensing data in the queue reaches the first quantity, a batch of the first quantity of the first sensing data is read out from the FIFO queue at one time for subsequent processing. In this way, the power consumption generated during the data reading process can be reduced, and the successful completion of data reading and data processing can be ensured even when the processor performance and memory performance are average.

[0102] Among them, the first quantity can be determined based on the processing requirements corresponding to the first function. For example, when the first function is the stroboscopic detection function, and the stroboscopic detection function requires performing a Fourier transform on the first sensing data to obtain the frequency of the light flicker and the intensity of the light flicker in the frequency domain analysis, and the Fourier transform requires 512 first sensing data that are continuous in time, then the first quantity can be set to 512. Another example is that if the first function has extremely high requirements for detection accuracy and precision, and calculating 1000 first sensing data can meet the accuracy and precision requirements of the first function, then the first quantity can be set to 1000.

[0103] In an embodiment, after reading the first quantity of the first sensing data in the FIFO queue, the second quantity of the first sensing data that was stored in the FIFO queue first is cleared; where the second quantity is less than the first quantity; when the second quantity of the first sensing data is collected, the second quantity of the first sensing data is sequentially stored in the FIFO queue.

[0104] In this embodiment, among the first quantity of the first sensing data read each time, it may include data partially the same as the previously read sensing data and the latest detected data. In this way, it can not only make the fullest use of the first sensing data to the greatest extent, but also continuously and uninterruptedly complete the first function, and can also analyze the change trend of the detection result.

[0105] For example, if the first integration time is 500 μs and the first quantity is 512, then the 512 first sensing data are the data included within 256 ms (256 ms = 500 μs × 512). Then, the first function can be completed based on different 512 first sensing data corresponding to different time periods (i.e., different 256 ms), and the 512 first sensing data corresponding to different 256 ms can have some data in common. As Figure 4 shown, it is a data flow schematic diagram for processing the first sensing data.

[0106] As Figure 4As shown, after reading the first set of 512 first sensing data from the queue (the 512 data are continuous in time and correspond to a total of 256 ms), the 64 (second quantity) first sensing data stored earliest in the queue can be cleared, and then the 64 latest acquired first sensing data are stored to obtain a second set of 512 first sensing data. 448 data in the second set of 512 data are the same as those in the previous time. Subsequently, this method is cycled to continuously clear and store data. In this way, the sensing data are updated, and the full utilization of the sensing data acquired each time is achieved.

[0107] In some embodiments, when it is detected that the first function is switched to the off state and the second function remains in the on state, the optical sensor acquires sensing data at an acquisition frequency determined based on the second integration time to obtain third sensing data; the third sensing data is processed corresponding to the second function to obtain a third processing result.

[0108] In this embodiment, since the first integration time corresponding to the first function is relatively short, as long as the first function is in the on state, regardless of whether the second function is in the on state or the off state, the optical sensor acquires data at the acquisition frequency corresponding to the first integration time. Once it is detected that the first function is in the off state and the second function still remains in the on state, the integration time of the optical sensor needs to be switched to the second integration time so that the optical sensor acquires sensing data according to the second integration time. In this way, the obtained third sensing data can be directly used for the processing of the second function, saving the step of determining the equivalent number of second sensing data, and enabling the electronic device to obtain the second processing result corresponding to the second function more quickly.

[0109] In some embodiments, processing the first sensing data corresponding to the first function to obtain a first processing result includes: processing the first sensing data corresponding to the first function to obtain the light flicker frequency and / or the light flicker intensity; processing the second sensing data corresponding to the second function to obtain a second processing result includes: processing the second sensing data corresponding to the second function to obtain the light intensity.

[0110] In this embodiment, when the first function is the stroboscopic detection function, the processing corresponding to the first function may include Fourier transform, signal denoising processing, frequency correction processing, etc., and the first processing result may include the frequency of the light flicker and the intensity of the light flicker. When the second function is the ambient light detection function, the processing corresponding to the second function may include optical parameter calculation according to relevant optical principles, etc., and the second processing result may include the light intensity.

[0111] In some embodiments, when the electronic device detects a photographing event, the first function and the second function are switched to the on state; when it is detected that both the first function and the second function are switched to the off state, the optical sensor is turned off.

[0112] In this embodiment, the first function may be a stroboscopic detection function, and the second function is an ambient light detection function. Then, when the electronic device is in a photographing scenario, the first function and the second function are in the on state. Taking a mobile phone as an example of the electronic device, when the automatic backlight of the mobile phone is turned on, it is necessary to obtain ambient light data, that is, the second function is in the on state. At this time, when the camera is turned on to take a photo, stroboscopic data will be obtained, that is, the first function is in the on state.

[0113] In some other embodiments, when the electronic device is in an automatic brightness adjustment scenario, the second function (ambient light detection function) is also in the on state. When the electronic device is in the eye protection mode, the first function is also in the on state.
