[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In one embodiment, as shown in FIG1 , a lens position adjustment method is provided. This embodiment is described by taking the method applied to an electronic device as an example. It is understandable that the method can also be applied to a server, and can also be applied to a system including an electronic device and a server, and is implemented through the interaction between the electronic device and the server. In this embodiment, the method includes the following steps:

[0031] S201, during image capture, obtaining a jitter position deviation of a lens, wherein the jitter position deviation is a deviation between an ideal position of the lens and an actual position of the lens.

[0032] The ideal position of the lens is the position where the lens should be located corresponding to the shooting angle of the lens, and the actual position of the lens is the position of the lens detected by the displacement sensor during the image shooting process.

[0033] In real life, when a user uses an electronic device to take photos, due to the user's misoperation, for example, the user's hand shakes when holding the electronic device, or the hand is hit when holding the electronic device, etc., the position of the lens may move, resulting in a deviation from the ideal position corresponding to the shooting angle of the lens, thereby causing the photographed photo to be blurred. In this embodiment, before performing optical image stabilization on the electronic device, it is necessary to first obtain the jitter position deviation between the ideal position of the lens and the actual position of the lens caused by the user's misoperation.

[0034] Typically, the processor of an electronic device can obtain data collected by each sensor in the electronic device through an Inter-Integrated Circuit (I2C) bus, and process the data collected by each sensor. Therefore, in this embodiment, as an optional implementation, the processor of the electronic device can obtain the jitter position deviation of the lens through a displacement sensor, or, as another optional implementation, the processor of the electronic device can determine the ideal position of the lens corresponding to the current shooting angle, and obtain the actual position of the lens through the displacement sensor, and obtain the jitter position deviation of the lens based on the ideal position of the lens and the obtained actual position of the lens.

[0035] S202 , in response to the jitter position deviation being greater than the adjustment threshold, controlling the motor to drive the lens to perform motion compensation to move the lens to an ideal position.

[0036] It should be noted that when the lens is in a stationary state, the position of the lens may fluctuate in the stationary state due to the noise of the motor's driving signal when the motor is driving the lens to move. In this embodiment, the electronic device may obtain the adjustment threshold value based on the fluctuation peak value in the data of the position fluctuation of the lens in the stationary state. For example, the electronic device may determine the average of the fluctuation peak values ​​in the data of the position fluctuation of the lens in the stationary state as the adjustment threshold value.

[0037] Optionally, in this embodiment, the electronic device may compare the jitter position deviation of the lens with an adjustment threshold to determine whether the jitter position deviation of the lens is greater than the adjustment threshold. If the electronic device determines that the jitter position deviation of the lens is greater than the adjustment threshold, it means that the lens jitter is relatively serious, and it is necessary to control the motor to drive the lens for motion compensation in response to the jitter position deviation of the lens being greater than the adjustment threshold, so as to move the lens to the above-mentioned ideal position to avoid the problem of blurred captured images due to lens jitter.

[0038] In addition, it should be noted that by simulating the method provided in this embodiment and obtaining a change curve of the actual position of the lens during image capture, it can be found that the lens position adjustment method provided in this embodiment can reduce the fluctuation range of the actual position of the lens, and can effectively reduce the influence of the jitter position deviation of the lens on the optical image stabilization.

[0039] In the above-mentioned lens position adjustment method, during the image shooting process, by obtaining the jitter position deviation between the ideal position of the lens and the actual position of the lens, the comparison result of the jitter position deviation of the lens and the adjustment threshold can be further obtained, so that during the image shooting process, it can be determined whether the lens has undergone a large degree of jitter according to the comparison result of the jitter position deviation of the lens and the adjustment threshold, so that when the jitter position deviation of the lens is greater than the adjustment threshold, it can be determined that the lens has undergone a large degree of jitter and needs to perform position compensation on the lens, and in response to the jitter position deviation being greater than the adjustment threshold, the motor is controlled to drive the lens for motion compensation to move the lens to the ideal position, so that the blur of the captured image caused by lens jitter can be optimized during the image shooting process. Compared with the method of improving the motor structure by simulating and evaluating the lens fluctuation in advance in the traditional technology, this method can optimize the captured image quality during the image shooting process and improve the optimization performance of optical image stabilization.

[0040] In this embodiment, the specific process of controlling the motor to drive the lens to perform motion compensation so as to move the lens to an ideal position is described in detail. In one embodiment, as shown in FIG. 2 , the above S202 includes:

[0041] S301, generating a driving signal according to the jitter position deviation.

[0042] Optionally, in this embodiment, after the processor of the electronic device obtains the above-mentioned lens shake position deviation, it can generate a driving signal according to the lens shake position deviation, that is, the generated driving signal can carry the lens shake position deviation information.

[0043] S302, controlling the motor to drive the lens to perform motion compensation according to the driving signal, so as to move the lens to an ideal position.

[0044] In this embodiment, the processor of the electronic device can control the motor to drive the lens to move for motion compensation according to the generated driving signal, so as to move the lens to the above-mentioned ideal position.

[0045] In this embodiment, if the jitter position deviation of the lens is greater than the adjustment threshold, it means that the lens has experienced relatively serious jitter. In this case, a driving signal can be generated according to the jitter position deviation of the lens, and the motor can be controlled according to the driving signal to drive the lens for motion compensation to move the lens to an ideal position, thereby avoiding the impact of relatively serious jitter of the lens on the quality of the captured image, optimizing the quality of the captured image, and improving the optical image stabilization performance of the electronic device.

[0046] The core point of optical image stabilization in the embodiment of the present application is to compare the jitter position deviation of the lens with the adjustment threshold to determine whether it is necessary to control the motor to drive the lens for motion compensation to move the lens to the ideal position. Therefore, the determination of the adjustment threshold plays an important role in the entire optical image stabilization optimization. In this embodiment, the method for determining the above adjustment threshold is explained in detail. In one embodiment, as shown in FIG3 , the method for determining the above adjustment threshold includes:

[0047] S401, obtaining a fluctuation curve corresponding to the position fluctuation of the lens in a static state.

[0048] It is understandable that the position fluctuation of the lens in a stationary state may be caused by the noise of the motor driving signal. In this embodiment, the electronic device can obtain the position fluctuation data of the lens in a stationary state through a displacement sensor, and generate a fluctuation curve corresponding to the position fluctuation of the lens in a stationary state based on the obtained position fluctuation data of the lens in a stationary state.

[0049] S402, determining a fluctuation peak value according to the fluctuation curve.

[0050] Optionally, in this embodiment, the electronic device can determine the peaks and troughs of the fluctuation curve corresponding to the position fluctuation of the lens in a stationary state, determine the peak value of the fluctuation curve based on the peaks and troughs of the fluctuation curve, and then determine the fluctuation peak value corresponding to the above fluctuation curve according to the peak of the fluctuation curve.

[0051] S403: Determine an adjustment threshold according to the fluctuation peak value and a preset adjustment coefficient.

[0052] The preset adjustment coefficient has a value range of 0-1. The larger the adjustment coefficient is, the greater the optimization of the jitter position deviation is. The adjustment coefficients corresponding to different motor structures are also different. In this embodiment, the value of the preset adjustment coefficient can be determined according to the structure of the above motor. As a preferred method, the optimal value of the preset adjustment coefficient is generally 0.5-0.8.

[0053] In this embodiment, as an optional implementation, the electronic device may determine the product value of the determined fluctuation peak value and the preset adjustment coefficient as the above adjustment threshold.

[0054] In the present embodiment, the process by which the electronic device acquires the fluctuation curve corresponding to the position fluctuation of the lens in a stationary state is relatively simple, and the fluctuation curve corresponding to the position fluctuation of the lens in a stationary state can be acquired relatively quickly, so that the fluctuation peak value can be quickly determined based on the acquired fluctuation curve, and then the adjustment threshold can be quickly determined based on the determined fluctuation peak value and the preset adjustment coefficient, thereby ensuring the efficiency of determining the adjustment threshold; in addition, since the adjustment threshold is acquired based on the fluctuation curve corresponding to the position fluctuation of the lens in a stationary state, the determination of the adjustment threshold takes into account the influence of the noise of the motor driving signal on the image capturing process, thereby accurately determining whether it is necessary to control the motor to drive the lens for position compensation based on the determined adjustment threshold and the jitter position deviation between the ideal position of the lens and the actual position of the lens during the image capturing process, thereby ensuring the optimized performance of optical image stabilization.

[0055] In this embodiment, the specific process of determining the fluctuation peak value according to the fluctuation curve will be described in detail. In one embodiment, as shown in FIG4 , the above S402 includes:

[0056] S501, performing filtering processing on the peak value of the fluctuation curve to obtain a filtered fluctuation curve.

[0057] In this embodiment, the frequency of occurrence of the peak value of the fluctuation curve corresponding to the position fluctuation of the lens in a stationary state can be first determined, and then the peak value of the fluctuation curve can be filtered according to the frequency of occurrence of the peak value to obtain a filtered fluctuation curve. Optionally, in this embodiment, the electronic device can perform defect filtering on the peak value of the fluctuation curve according to the frequency of occurrence of the peak value of the fluctuation curve to obtain a filtered fluctuation curve.

[0058] S502, performing curve fitting processing on the filtered fluctuation curve to determine a fitted fluctuation curve.

[0059] Optionally, in this embodiment, after the electronic device filters the peak value of the fluctuation curve corresponding to the position fluctuation of the lens in a static state, it can perform curve fitting processing on the filtered fluctuation curve using a linear fitting method to determine the fitted fluctuation curve.

[0060] S503, determining a peak value from the fitted fluctuation curve, and using the determined peak value as a fluctuation peak value.

[0061] In this embodiment, the electronic device can determine the peak in the fitted fluctuation curve, determine the peak value in the fitted fluctuation curve according to the value corresponding to the peak in the fitted fluctuation curve, and determine the determined peak value as the above-mentioned fluctuation peak value.

[0062] In this embodiment, filtering processing is first performed on the curve peak of the fluctuation curve corresponding to the position fluctuation of the lens in a static state, so that the peak with relatively large changes in the fluctuation curve can be filtered out, and then the filtered fluctuation curve is subjected to curve fitting processing to determine the fitted fluctuation curve. A peak is determined from the fitted fluctuation curve as the fluctuation peak, which can avoid the determined fluctuation peak being the extreme position fluctuation of the lens in a static state, making the determined fluctuation peak more universal, and further making the adjustment threshold determined according to the fluctuation peak and the preset adjustment coefficient more accurate, thereby ensuring the accuracy of the determined adjustment threshold.

[0063] In the above scenario of obtaining the jitter position deviation of the lens, the electronic device can determine the jitter position deviation of the lens according to the acquisition angle of the lens and the data collected by the position sensor of the lens. In one embodiment, as shown in FIG5 , the above S201 includes:

[0064] S601, obtaining the acquisition angle of the lens.

[0065] In this embodiment, after the angle sensor of the lens collects the angle data of the lens, the collected angle data can be sent to the processor of the electronic device through the I2C bus. The processor of the electronic device can determine the collection angle of the lens based on the data collected by the angle sensor of the lens.

[0066] S602, determining an ideal position of the lens according to the acquisition angle.

[0067] In this embodiment, a correspondence between different acquisition angles and the ideal position of the lens corresponding to each acquisition angle can be established in advance. In the actual process of capturing images, after the acquisition angle of the lens is obtained, the ideal position of the lens corresponding to the acquisition angle of the lens can be determined from the pre-established correspondence.

[0068] S603: Determine the actual position of the lens according to the data collected by the lens position sensor.

[0069] In this embodiment, the lens position sensor can collect the position of the lens in real time and send the collected data to the processor of the electronic device. Therefore, the processor of the electronic device can determine the actual position of the lens based on the data collected by the lens position sensor in real time.

[0070] S604: Determine the jitter position deviation according to the ideal position and the actual position.

[0071] In this embodiment, after the electronic device determines the actual position of the lens and the ideal position of the lens corresponding to the acquisition angle, it can obtain the difference between the actual position of the lens and the ideal position of the lens and determine the difference as the jitter position deviation of the lens.

[0072] In this embodiment, the electronic device can relatively quickly acquire the acquisition angle of the lens and the data acquired by the position sensor of the lens, so that the ideal position of the lens can be quickly determined according to the acquisition angle of the lens, and the actual position of the lens can be quickly determined according to the data acquired by the position sensor of the lens, and then the jitter position deviation of the lens can be quickly determined according to the ideal position and actual position of the lens, thereby ensuring the efficiency of acquiring the jitter position deviation of the lens, and then ensuring the efficiency of optimizing the performance of optical image stabilization of the electronic device.

[0076] S3, determining the actual position of the lens according to the data collected by the lens position sensor.
