FIG. 2 is a schematic diagram of an image processing circuit in one embodiment. As shown in fig. 2, for convenience of explanation, only aspects of the image processing technology related to the embodiments of the present application are shown.
As shown in fig. 2, the image processing circuit includes an ISP processor 240 and control logic 250. The image data captured by the imaging device 210 is first processed by the ISP processor 240, and the ISP processor 240 analyzes the image data to capture image statistics that may be used to determine and/or control one or more parameters of the imaging device 210.

The image sensor 214 may include an array of color filters (e.g., Bayer filters), and the image sensor 214 may acquire light intensity and wavelength information captured with each imaging pixel of the image sensor 214 and provide a set of raw image data that may be processed by the ISP processor 240. The sensor 220 (e.g., gyroscope) may provide parameters of the acquired image processing (e.g., anti-shake parameters) to the ISP processor 240 based on the type of interface of the sensor 220. The sensor 220 interface may utilize an SMIA (Standard Mobile Imaging Architecture) interface, other serial or parallel camera interfaces, or a combination of the above.
In addition, the image sensor 214 may also send raw image data to the sensor 220, the sensor 220 may provide the raw image data to the ISP processor 240 based on the sensor 220 interface type, or the sensor 220 may store the raw image data in the image memory 230.
The ISP processor 240 processes the raw image data pixel by pixel in a variety of formats. For example, each image pixel may have a bit depth of 8, 10, 12, or 14 bits, and the ISP processor 240 may perform one or more image processing operations on the raw image data, gathering statistical information about the image data. Wherein the image processing operations may be performed with the same or different bit depth precision.
The ISP processor 240 may also receive image data from the image memory 230. For example, the sensor 220 interface sends raw image data to the image memory 230, and the raw image data in the image memory 230 is then provided to the ISP processor 240 for processing. The image Memory 230 may be a portion of a Memory device, a storage device, or a separate dedicated Memory within an electronic device, and may include a DMA (Direct Memory Access) feature.

The processed image data may be sent to image memory 230 for additional processing before being displayed. ISP processor 240 receives processed data from image memory 230 and performs image data processing on the processed data in the raw domain and in the RGB and YCbCr color spaces. The image data processed by ISP processor 240 may be output to display 260 for viewing by a user and/or further processed by a Graphics Processing Unit (GPU). Further, the output of the ISP processor 240 may also be sent to the image memory 230, and the display 260 may read image data from the image memory 230. In one embodiment, image memory 230 may be configured to implement one or more frame buffers.

The ISP control parameters may include gain levels and color correction matrices for automatic white balance and color adjustment (e.g., during RGB processing), as well as lens 212 shading correction parameters.
In one embodiment, when the electronic device acquires a shooting anti-shake instruction, the sensor (gyroscope) 220 is turned on, and first angular velocity data of the sensor (gyroscope) 220 is acquired during shooting by the imaging device (camera) 210. The sensor (gyroscope) 220 may transmit the acquired first angular velocity data to the ISP processor 240, or may transmit the first angular velocity data to the image memory 230 for storage.

FIG. 3 is a flow diagram of a method for gyroscope processing in one embodiment. The gyroscope processing method in this embodiment is described by taking the example of the gyroscope processing method running on the electronic device in fig. 1. As shown in fig. 3, the gyro processing method includes steps 302 to 308.
In the process of image shooting, when a user clicks a shutter to shoot, the exposure of an image is often finished in a moment. In the process of image exposure, the captured image is often blurred due to large or small shake, thereby causing inconvenience to the user. Therefore, anti-shake is performed in the shooting process, and a clearer image can be acquired.
In one embodiment, a photographing anti-shake mode may be set in the application program, and when the user selects the photographing anti-shake mode, the electronic device obtains a photographing anti-shake instruction. In another embodiment, information such as a gesture and a biometric feature (a fingerprint and a portrait) of the user may also be matched with preset information such as a preset gesture and a preset biometric feature (a preset fingerprint and a preset portrait), and when the matching is successful, the electronic device acquires the shooting anti-shake instruction. In another embodiment, the photographing anti-shake instruction may also be acquired by recognizing a voice, a selected instruction, or the like. The specific acquisition of the photographing anti-shake instruction is not limited thereto.
And step 304, starting the gyroscope according to the shooting anti-shake instruction.
The gyroscope is also called as an angular velocity sensor and can measure the rotation angular velocity of the electronic equipment during deflection and inclination. The gyroscopes include a fiber optic gyroscope, a laser gyroscope, a MEMS (Micro Electro Mechanical systems) gyroscope, and the like. The gyroscope in the above-described gyroscope processing method may be an optical fiber gyroscope, a laser gyroscope, a MEMS gyroscope, or the like, but is not limited thereto. The following is exemplified with respect to a MEMS gyroscope.
Fig. 4 is a schematic structural diagram of the MEMS gyroscope. The MEMS gyroscope consists of two masses 402 and 404 that constantly vibrate and constantly move in opposite directions. When a jitter is detected, i.e. an angular velocity Ω is applied, the coriolis effect F on each mass generates a force in the opposite direction, causing a change in capacitance. The capacitance difference is in direct proportion to the angular velocity, so that the angular velocity at the moment can be known by measuring the change of the capacitance value, and the first angular velocity data can be acquired.
And step 306, acquiring first angular speed data of the gyroscope in the shooting process of the camera.
Angular velocity refers to a vector that describes in physics the angle an object turns through per unit time as well as the direction of the turn. The first angular speed data refers to the angle of rotation and the direction of rotation of the electronic equipment in unit time during shooting of the camera. The larger the first angular velocity data is, the larger the angle indicating that the electronic apparatus is rotated is, and the larger the direction of the rotation is, the larger the shake of the electronic apparatus is.
In the shooting process of the camera, the preview process before shooting the image may be performed, or in the process of shooting the video, the camera acquires a plurality of consecutive frames of images, and may generate one first angular velocity data for each frame of image, or generate a plurality of first angular velocity data for one frame of image, or generate one first angular velocity data for a plurality of frames of images, which is not limited to this.
It can be understood that the real-time performance of processing each frame of image can be ensured by generating first angular velocity data for each frame of image, collecting the first angular velocity data generated by the gyroscope, and processing the corresponding image according to each first angular velocity data. And a plurality of first angular velocity data are generated for one frame of image, the first angular velocity data generated by the gyroscope are collected, and the corresponding frame of image is processed according to the plurality of first angular velocity data, so that the accuracy of image processing can be improved. And a first angular velocity data is generated for the multi-frame image, for example, when the electronic device shakes within a certain range, a first angular velocity data can be generated for the multi-frame image, the first angular velocity data generated by the gyroscope is collected, the multi-frame image is respectively processed according to the collected first angular velocity data, and the power consumption of the gyroscope can be reduced.
And 308, adjusting the vibration frequency of the gyroscope according to first angular velocity data, wherein the vibration frequency is in negative correlation with the shake of the electronic equipment which can be detected by the gyroscope, and the first angular velocity data is used for indicating the shake of the electronic equipment which is detected by the gyroscope.
The vibration frequency refers to the number of vibrations per second. Taking the MEMS gyroscope as an example, the vibration frequency is the number of times each second each mass in the MEMS gyroscope vibrates. The vibration frequency of each block is the same.
When the vibration frequency of the gyroscope is larger, the smaller the jitter can be detected by the gyroscope. When the vibration frequency of the gyroscope is smaller, the gyroscope can detect a large shake. That is, the vibration frequency is inversely related to the magnitude of the shake of the electronic apparatus that can be detected by the gyroscope. Therefore, when the shake of the electronic equipment is large, the gyroscope can obtain the shake of the detected electronic equipment only by a small vibration frequency, and correct first angular velocity data can be acquired. The first angular velocity data is used to indicate a magnitude of a shake of the electronic device detected by the gyroscope.
In the conventional gyro processing method, the vibration frequency of the gyro is generally set large to detect a small shake of the electronic device. However, this gyro processing method has a problem of high power consumption.
Gather the first angular velocity data of gyroscope in camera shooting process, can adjust the vibration frequency of gyroscope according to first angular velocity data. Specifically, when the acquired first angular velocity data is large, the vibration frequency of the gyroscope may be reduced; when the acquired first angular velocity data is small, the vibration frequency of the gyroscope may be increased.
The vibration frequency of the gyroscope is adjusted according to the first angular velocity data, and the range of the gyroscope for measuring jitter can be further improved. For example, when the vibration frequency of the gyroscope is 100Hz, the measurable range of jitter is 2 degrees or more, and when the vibration frequency of the gyroscope is adjusted to 150Hz based on the first angular velocity data, and the measurable range of jitter is 1 degree or more, the adjusted gyroscope can measure more minute jitter, increasing the range of jitter measurement of the gyroscope.
According to the gyroscope processing method, the gyroscope is started according to the obtained shooting anti-shake instruction, first angular velocity data of the gyroscope is collected in the shooting process of the camera, and the vibration frequency of the gyroscope is adjusted according to the first angular velocity data. The size of the vibration frequency of the gyroscope is in negative correlation with the size of the shake of the electronic equipment which can be detected by the gyroscope, namely, when the shake of the electronic equipment is large, the gyroscope can detect the shake only by a small vibration frequency, and therefore first angular velocity data is obtained. Therefore, the vibration frequency of the gyroscope is adjusted according to the shake of the electronic equipment, namely the first angular velocity data, so that the power consumption of the gyroscope can be reduced.
In one embodiment, adjusting the vibration frequency of the gyroscope based on the first angular velocity data comprises: when the first angular velocity data is greater than or equal to a first angular velocity threshold, reducing the vibration frequency of the gyroscope; and when the first angular velocity data is smaller than a second angular velocity threshold value, increasing the vibration frequency of the gyroscope, wherein the first angular velocity threshold value is larger than or equal to the second angular velocity threshold value.
As shown in fig. 5, when the gyroscope detects the electronic device shaking, the coriolis force of the gyroscope is as follows:
wherein the content of the first and second substances,
is the base vector of three axes of a spatial rotating coordinate system. r denotes the radius of motion, ω is the angular velocity, vrIs the radial movement speed, arIs the radial acceleration, aCoriolisIs the coriolis force acceleration.
From the above formula, when the Coriolis force a is appliedCoriolisFor small jitter, i.e. small angular velocities, a large radial movement velocity v is required when not changingrCan achieve the precision of the gyroscope, and the radial motion velocity vrIs in direct proportion to the vibration frequency. That is, the gyroscope requires a higher vibration frequency to detect a smaller jitter. When the vibration frequency of the gyroscope is high, large power consumption is also generated.
It is understood that when the first angular velocity data is greater than or equal to the first angular velocity threshold, a large jitter of the electronic device is indicated. And the magnitude of the vibration frequency of the gyroscope is inversely related to the magnitude of the shake of the electronic device that can be detected by the gyroscope. Therefore, when the shake of the electronic device is large, the gyroscope can detect the shake of the electronic device even with a small vibration frequency, so that correct first angular velocity data can be acquired. When the vibration frequency of the gyroscope is reduced, the power consumption of the gyroscope can be reduced, and therefore resources of electronic equipment are saved.
When the first angular velocity data is smaller than the second angular velocity threshold, it indicates that the shake of the electronic device is small. Therefore, it is necessary to increase the vibration frequency of the electronic device, so that the gyroscope can detect more minute jitter of the electronic device, and the range of measuring jitter by the gyroscope is increased.
In one embodiment, the correspondence relationship of the first angular velocity data and the vibration frequency may be set in advance; and when the first angular velocity data is greater than or equal to the first angular velocity threshold, determining a target vibration frequency of the gyroscope from the corresponding relation between the first angular velocity data and the vibration frequency according to the first angular velocity data, wherein the target vibration frequency is less than or equal to the vibration frequency.
It is understood that, in the correspondence relationship of the first angular velocity data and the vibration frequency, the larger the first angular velocity data is, the smaller the vibration frequency is. The corresponding relationship between the first angular velocity data and the vibration frequency may be set in the form of a table, or may be set in a functional relationship, such as an inverse function, but is not limited thereto.
For example, the corresponding relationship between the first angular velocity data and the vibration frequency is preset in the electronic device as follows: y is 1/(0.01 × x), where x is a value of the first angular velocity data and y is a value of the vibration frequency. And when the first angular speed data is 2 degrees, the vibration frequency is 100Hz, and the first angular speed threshold is 1 degree, and the first angular speed data is greater than or equal to the first angular speed threshold, determining that the target vibration frequency of the gyroscope is 50Hz from the corresponding relation between the first angular speed data and the vibration frequency.
In another embodiment, when the first angular velocity data is greater than or equal to the first angular velocity threshold, a difference between the first angular velocity data and the first angular velocity threshold is obtained, the difference is substituted into a direct proportional function of the difference and the reduction value to obtain a reduction value of the vibration frequency, and the reduction value is subtracted from the value of the vibration frequency of the gyroscope to obtain the target vibration frequency.
For example, the value of the first angular velocity data is 3 degrees, the vibration frequency of the gyroscope is 50Hz, the first angular velocity threshold value is 1 degree, and the direct proportional function of the difference value to the reduction value is y ═ 10x, where y is the reduction value and x is the difference value. The difference between the first angular velocity data and the first angular velocity threshold is 2 degrees, the difference 2 degrees is substituted into a direct proportional function y of the difference and the reduction value of 10x 220, and the reduction value 20 is subtracted from the value 50 of the vibration frequency of the gyroscope to obtain 30, that is, the target vibration frequency is 30 Hz.
Correspondingly, when the first angular velocity data is smaller than the second angular velocity threshold, the target vibration frequency of the gyroscope can be determined from the preset corresponding relation between the first angular velocity data and the vibration frequency according to the first angular velocity data; or obtaining a difference value between the first angular velocity data and the first angular velocity threshold value, substituting the difference value into a direct proportional function of the difference value and the increase value to obtain an increase value of the vibration frequency, and adding the increase value to the value of the vibration frequency of the gyroscope to obtain the target vibration frequency.
In the correspondence relationship between the first angular velocity data and the vibration frequency, the smaller the first angular velocity data is, the larger the vibration frequency is. The corresponding relationship between the first angular velocity data and the vibration frequency may be set in the form of a table, or may be set in a functional relationship, such as an inverse function, but is not limited thereto.
It should be noted that, when the first angular velocity data is greater than or equal to the first angular velocity threshold, or when the first angular velocity data is less than the second angular velocity threshold, the vibration frequency of the gyroscope is adjusted, that is, the vibration frequency of the gyroscope is reduced or increased, and the method of adjustment is not limited to the above implementation, and the specific implementation may be set according to the user requirement, but is not limited to this.
As shown in fig. 6, in one embodiment, collecting first angular velocity data of a gyroscope during camera shooting includes:
In the shooting process of the camera, the first angular velocity data of the preset number of gyroscopes can be collected. It is understood that the larger the preset number, i.e., the larger the number of the collected first angular velocity data, the more accurately the vibration frequency of the gyroscope can be adjusted. On the other hand, the larger the preset number is, the more the first angular velocity acquired by the gyroscope is, and the higher the power consumption of the gyroscope is. The preset number may be set or modified according to the user requirement, and is not limited herein.
In one embodiment, collecting first angular velocity data of a preset number of gyroscopes in a camera shooting process includes: in the shooting process of the camera, detecting the shake of the electronic equipment through a gyroscope to generate at least one piece of first angular velocity data; generating a data sequence from the at least one first angular velocity data; a preset amount of first angular velocity data is collected from the data sequence.
The data sequence refers to a sequence of at least one first angular velocity data. A preset number of first angular velocity data are collected from the data sequence, and the first angular velocity data may be collected from the latest moment in time sequence until the number of collected first angular velocity data reaches the preset number. The first angular velocity data of the preset number can also be acquired at intervals of a preset number, such as 1 interval of the first angular velocity data. The manner of collecting the preset number of first angular velocity data may be set according to the user requirement, and is not limited thereto.
It can be understood that the closer the time corresponding to the acquired first angular velocity data is, the more accurately the vibration frequency of the gyroscope can be adjusted.
When the first angular velocity data is greater than the first angular velocity threshold, reducing a vibration frequency of the gyroscope, including:
and step 604, when the preset number of first angular velocity data are all larger than the first angular velocity threshold, reducing the vibration frequency of the gyroscope.
It can be understood that, when the collected preset number of first angular velocity data are all greater than the first angular velocity threshold, it can be considered that the jitters of the electronic device within the time length corresponding to the collected first angular velocity data are all large, and then the vibration frequency of the gyroscope can be reduced, and the power consumption of the gyroscope is reduced.
When the first angular velocity data is less than the second angular velocity threshold, increasing the vibration frequency of the gyroscope, including:
and 606, when the preset number of first angular velocity data are all smaller than the second angular velocity threshold, increasing the vibration frequency of the gyroscope.
It can be understood that, when the collected preset number of first angular velocity data are all smaller than the second angular velocity threshold, it can be considered that the jitters of the electronic device within the time length corresponding to the collected first angular velocity data are all smaller, so that the vibration frequency of the gyroscope can be increased, and the range of the gyroscope for detecting the vibration can be increased.

According to the gyroscope processing method, the first angular velocity data of the gyroscopes in preset number are collected in the shooting process of the camera, and when the first angular velocity data in preset number are all larger than the first angular velocity threshold value, the vibration frequency of the gyroscopes is reduced, so that the power consumption of the gyroscopes can be reduced; when the preset number of first angular velocity data are all smaller than the second angular velocity threshold, the vibration frequency of the gyroscope is improved, and the range of the gyroscope for detecting vibration can be improved.

The target gyroscope may be determined from the at least two gyroscopes based on the first angular velocity data for the respective gyroscope. And adjusting the vibration frequency of the target gyroscope according to the first angular velocity data of the target gyroscope.
It is to be understood that the at least two gyroscopes of the electronic device may be different types of gyroscopes, such as fiber optic gyroscopes, laser gyroscopes, MEMS gyroscopes, etc., or may be the same type of gyroscope. The at least two gyroscopes in the electronic device may be gyroscopes with different property parameters, such as different vibration frequencies, different sampling frequencies, different sensitivity to jitter, etc., without being limited thereto.
According to the gyroscope processing method, when the electronic equipment comprises at least two gyroscopes, and the vibration frequencies of the at least two gyroscopes are lower than the preset frequency threshold, the target gyroscope is determined from the at least two gyroscopes according to the first angular velocity data of each gyroscope, the vibration frequency of the target gyroscope is adjusted according to the first angular velocity of the target gyroscope, and power consumption of the gyroscopes can be reduced.
In one embodiment, an electronic device includes at least one first gyroscope to detect capacitance values below a first capacitance threshold and at least one second gyroscope to detect capacitance values above a second capacitance threshold, the first capacitance threshold being less than or equal to the second capacitance threshold;
determining a target gyroscope from the at least two gyroscopes based on the first angular rate data, comprising:
and step 702, when the first angular velocity data is larger than the third angular velocity threshold, taking the second gyroscope as a target gyroscope.
Capacitance refers to a physical quantity that represents the capacity of a capacitor to hold a charge. The capacitance value refers to the amount of charge that the capacitor holds. The first gyroscope refers to a gyroscope for detecting capacitance values below a first capacitance threshold value and the second gyroscope refers to a gyroscope for detecting capacitance values above a second capacitance threshold value. In the gyroscope, when the capacitance value is larger, the gyroscope is sensitive to larger jitter, and the larger jitter can be quickly detected. When the capacitance value is small, the gyroscope is sensitive to small jitter, and the small jitter can be detected quickly.
Taking a MEMS gyroscope as an example, as shown in fig. 4, two masses 402 and 404 are the two poles of a plate capacitor. The sensitivity of the gyroscope to capacitance can be varied by varying the facing area between the two masses, and by adding different dielectrics between the two masses. When the gyroscope is sensitive to the small capacitance of the plate capacitor, the gyroscope may detect a smaller capacitance value, and then the gyroscope may act as the first gyroscope. When the gyroscope is sensitive to the large capacitance of the plate capacitor, the gyroscope can detect a large capacitance value, and then the gyroscope can be used as a second gyroscope.
In another embodiment, the plate capacitor may output a voltage signal, and when the voltage detection device in the gyroscope detects a smaller voltage, which indicates that the gyroscope is sensitive to a small capacitance, and detects a smaller capacitance value, the gyroscope may be the first gyroscope. When a larger voltage is detected during voltage detection in the gyroscope, indicating that the gyroscope is sensitive to a large capacitance, and the larger voltage can be detected, the gyroscope can be a second gyroscope.
And when the first angular velocity data is larger than the third angular velocity threshold, the first angular velocity data is larger, the shake of the electronic equipment is larger, and the second gyroscope is used as a target gyroscope.
And step 704, when the first angular velocity data is less than or equal to a fourth angular velocity threshold, taking the first gyroscope as a target gyroscope, wherein the third angular velocity threshold is greater than or equal to the fourth angular velocity threshold.
And when the first angular velocity data is smaller than or equal to the fourth angular velocity threshold, the first angular velocity data is smaller, the shake of the electronic equipment is smaller, and the first gyroscope is taken as a target gyroscope.
According to the gyroscope processing method, when the first angular velocity data is larger than the third angular velocity threshold value, the second gyroscope is used as the target gyroscope; when the first angular velocity data is less than or equal to the fourth angular velocity threshold, the first gyroscope is used as a target gyroscope, the target gyroscope is determined from the plurality of gyroscopes according to the size of the first angular velocity data, and a more accurate gyroscope can be determined to adjust a more accurate vibration frequency.
In one embodiment, the gyroscope processing method further includes: and adjusting the sampling frequency of the gyroscope according to the first angular velocity data.
The sampling frequency refers to the number of times per second the gyroscope acquires the first angular velocity data.
It can be understood that the larger the sampling frequency is, the more the first angular velocity data is acquired by the gyroscope, the higher the power consumption of the gyroscope is, and the higher the accuracy of processing the gyroscope according to the first angular velocity data is.
According to the gyroscope processing method, the sampling frequency of the gyroscope is adjusted according to the first angular velocity data, and the relation between the power consumption of the gyroscope and the accuracy of gyroscope processing can be balanced.
In one embodiment, adjusting the sampling frequency of the gyroscope based on the first angular velocity data comprises: when the first angular velocity data is larger than or equal to the fifth angular velocity threshold, increasing the sampling frequency of the gyroscope; and when the first angular velocity data is smaller than a sixth angular velocity threshold, reducing the sampling frequency of the gyroscope, wherein the fifth angular velocity threshold is larger than or equal to the sixth angular velocity threshold.
It is understood that when the first angular velocity data is greater than or equal to the fifth angular velocity threshold, it indicates that the first angular velocity data is larger and the jitter of the electronic device is larger. In order to ensure the stability and accuracy of images in the shooting process of the camera, the camera needs to be subjected to larger shake compensation. Therefore, the sampling frequency of the gyroscope needs to be increased, more first angular velocity data can be acquired by a larger sampling frequency, and the camera can be more accurately subjected to jitter compensation according to the acquired first angular velocity data.
When the first angular velocity data is smaller than the sixth angular velocity threshold, the first angular velocity data is smaller, the shake of the electronic device is smaller, and the acquired image in the shooting process of the camera is clearer. Therefore, only minor shake compensation needs to be performed on the camera. When the first angular velocity data is smaller than the sixth angular velocity threshold, the sampling frequency of the gyroscope is reduced, and the power consumption of the gyroscope can be reduced.
According to the processing method of the gyroscope, when the first angular velocity data is larger than or equal to the fifth angular velocity threshold, the sampling frequency of the gyroscope is increased, more first angular velocity data can be obtained, and therefore the camera can be subjected to shake compensation more accurately; when the first angular velocity data is smaller than the sixth angular velocity threshold, the sampling frequency of the gyroscope is reduced, and the power consumption of the gyroscope can be reduced.
In one embodiment, the correspondence relationship of the first angular velocity data to the sampling frequency may be set in advance; and when the first angular velocity data is greater than or equal to the fifth angular velocity threshold, determining a target sampling frequency of the gyroscope from the corresponding relation between the first angular velocity data and the sampling frequency according to the first angular velocity data, wherein the target sampling frequency is greater than or equal to the sampling frequency.
It is understood that, in the correspondence relationship of the first angular velocity data to the sampling frequency, the larger the first angular velocity data, the larger the sampling frequency. The corresponding relationship between the first angular velocity data and the sampling frequency may be set in a table form, or may be set in a functional relationship, such as a proportional function, but is not limited thereto.
For example, the corresponding relationship between the first angular velocity data and the sampling frequency is preset in the electronic device as follows: y is 50x, where x is the value of the first angular velocity data and y is the value of the sampling frequency. And when the first angular speed data is 2 degrees, the sampling frequency is 50Hz, and the first angular speed threshold is 1 degree, and the first angular speed data is greater than or equal to the first angular speed threshold, determining the target sampling frequency of the gyroscope to be 100Hz from the corresponding relation between the first angular speed data and the sampling frequency.
In another embodiment, when the first angular velocity data is greater than or equal to the fifth angular velocity threshold, a difference between the first angular velocity data and the fifth angular velocity threshold is obtained, the difference is substituted into a direct proportional function of the difference and the increase to obtain an increase of the sampling frequency, and the increase is added to the value of the sampling frequency of the gyroscope to obtain the target sampling frequency.
For example, the first angular velocity data has a value of 2 degrees, the sampling frequency of the gyroscope is 50Hz, the first angular velocity threshold is 1 degree, and the direct proportional function of the difference value to the boost value is y-20 x, where y is the boost value and x is the difference value. The difference between the first angular velocity data and the first angular velocity threshold is 1 degree, the difference 1 degree is substituted into a direct proportional function y of the difference and the increase value, i.e., 20x 20 1 20, and the increase value 20 is added to the value 50 of the sampling frequency of the gyroscope to obtain 70, i.e., the target sampling frequency is 70 Hz.
Correspondingly, when the first angular velocity data is smaller than the sixth angular velocity threshold, the target sampling frequency of the gyroscope can be determined from the preset corresponding relation between the first angular velocity data and the sampling frequency according to the first angular velocity data; the difference between the first angular velocity data and the sixth angular velocity threshold value can also be obtained, the difference is substituted into a direct proportional function of the difference and the reduction value to obtain a reduction value of the sampling frequency, and the reduction value is subtracted from the value of the sampling frequency of the gyroscope to obtain the target sampling frequency.
It should be noted that, when the first angular velocity data is greater than or equal to the fifth angular velocity threshold, or when the first angular velocity data is less than the sixth angular velocity threshold, the sampling frequency of the gyroscope is adjusted, that is, the sampling frequency of the gyroscope is increased or decreased, and the method of adjustment is not limited to the foregoing implementation manner, and the specific implementation manner may be set according to a user requirement, and is not limited to this.
In one embodiment, the method further comprises: acquiring second angular velocity data of the adjusted gyroscope; and carrying out shake compensation on the camera according to the second angular velocity data.
The shake compensation refers to a process of compensating shake in the shooting process of the camera, and the image definition in the shooting process of the camera can be improved.
Specifically, when the vibration frequency of the gyroscope is adjusted, the second angular velocity data of the gyroscope with the adjusted vibration frequency is acquired. And when the sampling frequency of the gyroscope is adjusted, acquiring second angular velocity data of the gyroscope with the adjusted sampling frequency. And when the vibration frequency and the sampling frequency of the gyroscope are adjusted, acquiring second angular velocity data of the gyroscope after the vibration frequency and the sampling frequency are adjusted.
The camera may be shake-compensated based on the second angular velocity data, and shake compensation may be performed by an OIS (Optical image stabilization).
As shown in fig. 8, during shooting by the camera 802, a gyroscope (Gyro Sensor)804 detects a shake of the electronic device to generate first angular velocity data, an OIS Controller (OIS Controller)806 determines a compensation amount of the camera 802 by calculating the first angular velocity data, moves the camera 802 according to a compensation amount control Motor (Motor)808, and detects a moving distance of the camera 802 using a Hall Sensor (Hall Sensor)810 and provides the detected moving distance to the OIS Controller 806.
According to the gyroscope processing method, the adjusted second angular velocity data of the gyroscope is collected, the camera is subjected to shake compensation according to the second angular velocity data, and a more accurate and clearer image can be obtained.
It should be understood that, although the steps in the flowcharts of fig. 2, 6 to 7 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 6-7 may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least some of the sub-steps or stages of other steps.
