Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

The following describes a method, an apparatus, a device, and a medium for detecting optical anti-shake performance of a terminal device according to embodiments of the present disclosure with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method for detecting optical anti-shake performance of a terminal device according to an embodiment of the disclosure.

The embodiment of the disclosure is exemplified by the optical anti-shake performance detection method of the terminal device being configured in the optical anti-shake performance detection device of the terminal device, and the optical anti-shake performance detection device of the terminal device can be applied to any electronic device, so that the electronic device can execute the optical anti-shake performance detection function of the terminal device.

The electronic device may be any device with computing capability, for example, a computer, a test device, an intelligent robot, etc., which is not limited in this disclosure.

As shown in fig. 1, the method for detecting optical anti-shake performance of a terminal device may include the following steps:

step 101, when the terminal equipment is in a shooting mode, controlling the movable device to drive the terminal equipment to move in an accelerating mode.

In the embodiment of the present disclosure, the terminal device may be a hardware device having various operating systems, touch screens and/or display screens, such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and the like, which is not limited in this disclosure.

In embodiments of the present disclosure, the movable device, such as a movable clamp, an analog robot, etc., is not limited in this disclosure.

In the embodiment of the disclosure, the shooting mode may include a shooting mode, and a preview mode.

In the embodiment of the disclosure, when the terminal device is in the shooting mode, the movable device may be controlled to drive the terminal device to perform accelerated movement.

It can be understood that when the movable device drives the terminal device to move at a uniform speed, the optical anti-shake device in the terminal device does not shake, that is, the moving distance (or shake distance) of the optical anti-shake device is zero, so in the present disclosure, in order to effectively detect the anti-shake performance of the optical anti-shake device, the movable device can be controlled to drive the terminal device to move at an accelerated speed, so that the optical anti-shake device can shake in a direction opposite to the moving direction of the terminal device in a state that the terminal device moves at an accelerated speed, so as to avoid shake of an imaging module in the terminal device, and further improve the shooting quality of the terminal device.

Step 102, obtaining a target value in a driving register of an optical anti-shake device in the terminal equipment, wherein the target value is used for indicating the moving distance of the optical anti-shake device.

In the embodiment of the disclosure, in order to avoid shake of an imaging module in the terminal device in the process that the movable device drives the terminal device to accelerate movement, the optical anti-shake device in the terminal device can shake in a direction opposite to the movement direction of the terminal device, so that in the disclosure, the movement distance of the optical anti-shake device can be obtained.

In the embodiment of the disclosure, the jitter distances of the optical anti-jitter device in all directions may be periodically obtained by the driving register of the optical anti-jitter device during the jitter process of the optical anti-jitter device, so as to obtain all the storage values, and all the storage values are stored in the driving register.

As an example, the optical anti-shake apparatus may periodically obtain a shake distance of the optical anti-shake apparatus in a first direction, and obtain a shake distance of the optical anti-shake apparatus in a second direction, where each obtained storage value may include a value of the first direction for indicating the shake distance of the optical anti-shake apparatus in the first direction and a value of the second direction for indicating the shake distance of the optical anti-shake apparatus in the second direction.

The first direction is perpendicular to the second direction, and the first direction and the second direction are perpendicular to the normal direction of the plane where the lens of the terminal device is located. For example, taking the normal to the plane in which the lens lies as the Z axis as an example, the first direction may be parallel to the X axis (e.g., the first direction may be a positive and negative X axis direction) and the second direction may be parallel to the Y axis (e.g., the second direction may be a positive and negative Y axis direction). Wherein, as shown in fig. 2, the X axis and the Y axis are parallel to two sides of the terminal device, respectively.

For example, each of the stored values may be OIS hall code values in the related art, including hall code values in the positive X-axis direction (or negative X-axis direction) and hall code values in the positive Y-axis direction (or negative Y-axis direction), where the hall code values in the positive X-axis direction (or negative X-axis direction) are used to indicate the shake distance of the optical anti-shake device in the positive X-axis direction (or negative X-axis direction), and the hall code values in the positive Y-axis direction (or negative Y-axis direction) are used to indicate the shake distance of the optical anti-shake device in the positive Y-axis direction (or negative Y-axis direction).

Thus, in the present disclosure, the moving distance of the optical anti-shake device may be determined according to the value of the first direction and the value of the second direction in the stored values, for example, the shake distance of the optical anti-shake device in the first direction is determined according to the value of the first direction in the stored values, and the shake of the optical anti-shake device in the second direction is determined according to the value of the second direction in the stored values And a distance, so that a moving distance of the optical anti-shake apparatus is determined according to a shake distance of the optical anti-shake apparatus in a first direction and a shake distance of the optical anti-shake apparatus in a second direction. For example, if the jitter distance of the optical anti-shake device in the first direction is c and the jitter distance of the optical anti-shake device in the second direction is d, the moving distance of the optical anti-shake device may be (c) ² +d ² ) ^1/2 。

In the embodiment of the disclosure, the target value may be one of the stored values stored in the driving register of the optical anti-shake device, for example, may be the stored value stored last time in the driving register of the optical anti-shake device. Wherein the target value is used for indicating a second moving distance of the optical anti-shake device.

In the embodiment of the disclosure, the target value in the driving register of the optical anti-shake device in the terminal device may be obtained.

It should be noted that, the electronic device may not be able to directly read the target value stored in the driving register of the optical anti-shake device of the terminal device, for example, in an application scenario where the terminal device leaves the factory to perform optical anti-shake performance detection, the electronic device may be a test device, and the test device may not be able to directly read the target value from the driving register of the optical anti-shake device of the terminal device, so in one possible implementation of the embodiment of the present disclosure, the terminal device may read each set of storage values from the driving register, and may write each set of storage values into a set node readable by the electronic device, so that the electronic device may read the target value from each set of storage values of the set node.

Step 103, determining whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the target value.

In the embodiment of the present disclosure, the setting requirement may be a preset requirement, where the setting requirement is used to indicate that the optical anti-shake device of the terminal device has better anti-shake performance.

In the embodiment of the disclosure, whether the anti-shake performance of the optical anti-shake device of the terminal equipment meets the set requirement can be determined according to the target value.

According to the method for detecting the optical anti-shake performance of the terminal equipment, when the terminal equipment is in a shooting mode, the movable device is controlled to drive the terminal equipment to move in an accelerating mode; acquiring a target value in a driving register of an optical anti-shake device in terminal equipment, wherein the target value is used for indicating the moving distance of the optical anti-shake device; and determining whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the target value. Therefore, when the movable device drives the terminal equipment to move in an accelerating way, the anti-shake performance of the optical anti-shake device in the terminal equipment can be effectively detected according to the moving distance of the optical anti-shake device in the terminal equipment.

In order to clearly explain how to determine whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the target value in the above embodiments of the disclosure, the disclosure further provides a method for detecting the optical anti-shake performance of the terminal device.

Fig. 3 is a flowchart illustrating a method for detecting optical anti-shake performance of a terminal device according to another embodiment of the disclosure.

As shown in fig. 3, the method for detecting optical anti-shake performance of the terminal device may include the following steps:

step 301, when the terminal device is in the shooting mode, controlling the movable device to drive the terminal device to move in an accelerating way.

Step 302, obtaining a target value in a driving register of an optical anti-shake device in a terminal device, wherein the target value is used for indicating a moving distance of the optical anti-shake device.

In an embodiment of the disclosure, the target value may include a first value and a second value, where the first value may be used to indicate a jitter distance of the optical anti-shake device in a first direction, and the second value may be used to indicate a jitter distance of the optical anti-shake device in a second direction.

The explanation of the first direction and the second direction can be referred to the above embodiments, and will not be repeated here.

The execution of steps 301 to 302 may refer to the execution of any embodiment of the present disclosure, and will not be described herein.

Step 303, determining whether the first value is located in the first value interval, and determining whether the second value is located in the second value interval.

Step 304, determining that the anti-shake performance of the optical anti-shake device meets the set requirement in response to the first value being located in the first value range and/or the second value being located in the second value range.

In step 305, in response to the first value not being located in the first value interval and the second value not being located in the second value interval, it is determined that the anti-shake performance of the optical anti-shake device does not meet the set requirement.

It should be noted that, the explanation of the setting requirement in the above embodiments of the present disclosure is also applicable to this embodiment, and is not repeated here.

In an embodiment of the disclosure, the first value interval may be used to indicate a jitter distance interval of the optical anti-jitter device in the first direction when an anti-jitter performance of the optical anti-jitter device meets a set requirement.

In an embodiment of the disclosure, the second value interval may be used to indicate a jitter distance interval of the optical anti-jitter device in the second direction when an anti-jitter performance of the optical anti-jitter device meets a set requirement.

As a possible implementation manner, the first value interval and the second value interval may be determined according to a plurality of reference terminal devices, where anti-shake performance of the optical anti-shake device of the reference terminal device meets the set requirement.

As an example, a plurality of terminal apparatuses (referred to as reference terminal apparatuses in this disclosure) in which the optical anti-shake apparatuses are built in and each of which satisfies the setting requirements may be determined. For each reference terminal device, the movable device can be controlled to drive the reference terminal device to move in an accelerating manner, a stored value (such as a stored value stored last time) in a driving register of the optical anti-shake device in the reference terminal device is obtained, a first value interval (i.e. the upper limit of the first value interval is the maximum value in the first direction and the lower limit is the minimum value in the first direction) is determined according to the value of the first direction in the driving register in each reference terminal device, and a second value interval (i.e. the upper limit of the second value interval is the maximum value in the second direction and the lower limit is the minimum value in the second direction) is determined according to the value of the second direction in the driving register in each reference terminal device.

Therefore, the accuracy of the anti-shake performance detection result of the optical anti-shake device can be improved by determining the first value interval and the second value interval according to the plurality of reference terminal devices.

In the present disclosure, it may be determined whether a first value in the target value is located in a first value interval, and whether a second value is located in a second value interval; when the first value is located in the first value interval and/or the second value is located in the second value interval, the anti-shake performance of the optical anti-shake device can be determined to meet the set requirement; when the first value is not located in the first value interval and the second value is not located in the second value interval, it can be determined that the anti-shake performance of the optical anti-shake device does not meet the set requirement.

It should be noted that, step 304 and step 305 are implemented in two parallel, and may be alternatively executed in practical application.

According to the optical anti-shake performance detection method, whether the first value is located in the first value interval or not is judged, and whether the second value is located in the second value interval or not is judged; determining that the anti-shake performance of the optical anti-shake device meets the set requirement in response to the first value being located in the first value interval and/or the second value being located in the second value interval; and determining that the anti-shake performance of the optical anti-shake device does not meet the set requirement in response to the first value not being located in the first value interval and the second value not being located in the second value interval. Therefore, whether the anti-shake performance of the optical anti-shake device meets the set requirement can be effectively and accurately determined according to the first value and the second value in the target value, and the optical anti-shake performance of the optical anti-shake device in the terminal equipment is effectively detected.

In order to clearly explain how to determine whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the target value in any of the above embodiments of the disclosure, the disclosure further provides a method for detecting the optical anti-shake performance of the terminal device.

Fig. 4 is a flowchart illustrating a method for detecting optical anti-shake performance of a terminal device according to another embodiment of the disclosure.

As shown in fig. 4, the method for detecting optical anti-shake performance of the terminal device may include the following steps:

step 401, when the terminal device is in the shooting mode, controlling the movable device to drive the terminal device to move in an accelerating way.

Step 402, obtaining a target value in a driving register of an optical anti-shake device in a terminal device.

The execution of steps 401 to 402 may refer to the execution of any embodiment of the present disclosure, and will not be described herein.

Step 403, determining a first moving distance of the terminal device driven by the movable device.

In the embodiment of the present disclosure, the first moving distance may be a distance that the terminal device moves under the driving of the movable device when the movable device drives the terminal device to perform the acceleration movement.

In the embodiment of the disclosure, the first moving distance of the terminal equipment driven by the movable device can be determined.

It should be noted that, the execution timing of the step 402 and the step 403 is not limited in this disclosure, that is, the step 402 and the step 403 may be executed in parallel, or the step 403 and the step 402 may be executed sequentially, for example, the step 403 may be executed before the step 402, and in this embodiment of the disclosure, only the step 402 is executed before the step 403.

Step 404, determining a second moving distance of the optical anti-shake device according to the target value.

In the embodiment of the disclosure, the shake distance of the optical anti-shake device in the first direction may be determined according to the first value, and the shake distance of the optical anti-shake device in the second direction may be determined according to the second value, so that the second movement distance of the optical anti-shake device may be determined according to the shake distance in the first direction and the shake distance in the second direction.

As an example, the first value is marked as k ₁ The shaking distance s of the optical shaking prevention device in the first direction ₁ Can be determined according to the following formula:

s ₁ ＝k ₁ *K _H ； (1)

wherein K is _H Is the hall sensitivity (sensitivity) coefficient.

Marking the second value as k ₂ The shaking distance s of the optical shaking prevention device in the second direction ₂ Can be determined according to the following formula:

s ₂ ＝k ₂ *K _H ； (2)

In the embodiment of the disclosure, after determining the shake distance of the optical anti-shake apparatus in the first direction and the shake distance in the second direction, the second movement distance of the optical anti-shake apparatus may be determined according to the shake distance in the first direction and the shake distance in the second direction.

For example, the second moving distance of the mark optical anti-shake device is s, and the shake distance of the optical anti-shake device in the first direction is s ₁ The shaking distance of the optical anti-shaking device in the second direction is s ₂ The second moving distance s of the optical anti-shake apparatus may be determined according to the following formula:

step 405, determining a difference between the first movement distance and the second movement distance.

In the disclosed embodiments, a difference between the first movement distance and the second movement distance may be determined. The difference may be a difference value, or the difference may be an absolute value of the difference value, or the difference may be a square of the difference value, or the like, which is not limited by the present disclosure.

As an example, if the first moving distance is L and the second moving distance is s, the difference between the first moving distance and the second moving distance may be k×l-s|, where K is a set coefficient or a set weight.

Step 406, determining that the anti-shake performance of the optical anti-shake device meets the set requirement when the difference is not greater than the difference threshold.

In the embodiment of the present disclosure, the difference threshold may be a preset value.

As one possible implementation manner, a plurality of terminal apparatuses (referred to as reference terminal apparatuses in the present disclosure) having the optical anti-shake apparatuses built therein and each satisfying a set requirement may be determined, and the difference threshold may be determined according to the plurality of reference terminal apparatuses.

As an example, for each reference terminal device, the above method may be used to determine the moving distance of the reference terminal device under the driving of the movable device (denoted as the third moving distance in the present disclosure) and determine the moving distance of the optical anti-shake device in the reference terminal device (denoted as the fourth moving distance in the present disclosure), so that the difference between the third moving distance and the fourth moving distance of the reference terminal device may be determined according to the third moving distance and the fourth moving distance of the reference terminal device, and may be used as the reference difference.

After determining the reference difference of each reference terminal device, the average value of each reference difference may be used as a difference threshold, or the median of each reference difference may also be used as a difference threshold, or the maximum value (or the minimum value) of each reference difference may be used as a difference threshold, or the like, which is not limited by the present disclosure.

In the embodiment of the disclosure, when the difference between the first moving distance and the second moving distance is not greater than the difference threshold, it is indicated that the anti-shake performance of the optical anti-shake device in the terminal equipment is better, so that it can be determined that the anti-shake performance of the optical anti-shake device meets the set requirement.

Step 407, determining that the anti-shake performance of the optical anti-shake device does not meet the set requirement when the difference is greater than the difference threshold.

In the embodiment of the disclosure, when the difference between the first moving distance and the second moving distance is greater than the difference threshold, it is indicated that the anti-shake performance of the optical anti-shake device in the terminal equipment is poor, and therefore, it may be determined that the anti-shake performance of the optical anti-shake device does not meet the set requirement.

It should be noted that, step 406 and step 407 are implemented in two parallel implementations, and may be alternatively executed in actual application.

As an application scenario, taking an example of optical anti-shake performance detection before the terminal device leaves the factory, after a first moving distance of the terminal device and a second moving distance of an optical anti-shake device of the terminal device are obtained, a difference between the first moving distance and the second moving distance can be determined. When the difference is larger than the difference threshold, it can be determined that the anti-shake performance of the optical anti-shake device of the terminal equipment cannot meet the set requirement (i.e. does not meet the factory condition), so that the terminal equipment can be modulated again after being returned to the factory; and when the difference is not greater than the difference threshold, it can be determined that the anti-shake performance of the optical anti-shake device of the terminal device meets the set requirement (i.e., meets the factory condition), so that the terminal device can be shipped.

According to the optical anti-shake performance detection method of the terminal equipment, the second moving distance of the optical anti-shake device is determined according to the target value; determining a difference between the first movement distance and the second movement distance; under the condition that the difference is not larger than a difference threshold value, determining that the anti-shake performance of the optical anti-shake device meets the set requirement; and under the condition that the difference is larger than the difference threshold value, determining that the anti-shake performance of the optical anti-shake device does not meet the set requirement. Thus, the second movement distance of the optical anti-shake device can be effectively determined based on the target value in the drive register of the optical anti-shake device, so that the optical anti-shake performance of the terminal device can be effectively determined according to the difference between the first movement distance of the terminal device and the second movement distance of the optical anti-shake device. In addition, the optical anti-shake performance of the terminal equipment is detected according to the difference between the moving distance of the terminal equipment and the moving distance of the optical anti-shake device, and the accuracy and reliability of the optical anti-shake performance detection result can be improved.

In order to clearly illustrate how to determine the first moving distance of the terminal device in any embodiment of the present disclosure, the present disclosure further provides a method for detecting the optical anti-shake performance of the terminal device.

Fig. 5 is a flowchart illustrating a method for detecting optical anti-shake performance of a terminal device according to another embodiment of the disclosure.

As shown in fig. 5, the method for detecting optical anti-shake performance of the terminal device may include the following steps:

in step 501, when the terminal device is in the shooting mode, the movable device is controlled to drive the terminal device to move in an accelerating way.

The implementation of step 501 may refer to the implementation of any embodiment of the present disclosure, which is not described herein.

Step 502, determining acceleration of movement of the terminal device.

In the embodiment of the disclosure, the acceleration of the movement of the terminal device may be determined. For example, an accelerometer, an acceleration sensor, a speed measuring device mounted on the terminal device, or the like may be used to determine the acceleration of the movement of the terminal device, which is not limited in this disclosure.

Step 503, determining a movement duration of the terminal device.

In the embodiment of the disclosure, the movement duration of the terminal device may be determined. For example, a timer may be used to record the length of movement of the terminal device.

Step 504, determining a first moving distance of the terminal equipment according to the acceleration and the moving duration.

In the embodiment of the present disclosure, the first movement distance of the terminal device may be determined according to the acceleration and the movement duration.

For example, if the mark acceleration is a, the movement duration is t, and the first movement distance L of the terminal device, L may be determined according to the following formula:

step 505, obtaining a target value in a driving register of the optical anti-shake device in the terminal device, where the target value is used to indicate a second movement distance of the optical anti-shake device.

Step 506, determining whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the first moving distance and the target value.

As an example, the second movement distance of the optical anti-shake apparatus may be determined according to the target value, and whether the anti-shake performance of the optical anti-shake apparatus of the terminal device satisfies the set requirement may be determined according to the first movement distance and the second movement distance. For example, when the difference between the first moving distance and the second moving distance is smaller, the better the anti-shake performance of the optical anti-shake device in the terminal device is indicated, and therefore, in the present disclosure, when the difference between the first moving distance and the second moving distance is smaller, it may be determined whether the anti-shake performance of the optical anti-shake device of the terminal device meets the set requirement.

And when the difference between the first moving distance and the second moving distance is higher, the worse the anti-shake performance of the optical anti-shake device in the terminal device is indicated, so in the present disclosure, when the difference between the first moving distance and the second moving distance is larger, it may be determined that the anti-shake performance of the optical anti-shake device of the terminal device does not meet the set requirement.

As one possible implementation, a difference between the first movement distance and the second movement distance may be determined; under the condition that the difference is not larger than a difference threshold value, determining that the anti-shake performance of the optical anti-shake device meets the set requirement; and under the condition that the difference is larger than the difference threshold value, determining that the anti-shake performance of the optical anti-shake device does not meet the set requirement.

The execution of steps 505 to 506 may refer to the execution of any embodiment of the present disclosure, and will not be described herein.

The optical anti-shake performance detection method of the terminal equipment comprises the steps of determining the moving acceleration of the terminal equipment; determining the moving time length of the terminal equipment; and determining a first moving distance of the terminal equipment according to the acceleration and the moving duration. Therefore, the first moving distance of the terminal equipment can be effectively and accurately determined according to the acceleration and the moving duration of the terminal equipment.

Based on the above embodiments of the present disclosure, in order to clearly explain how to obtain a target value in a driving register of an optical anti-shake device in a terminal device, the present disclosure also proposes a method for detecting optical anti-shake performance of the terminal device.

Fig. 6 is a flowchart illustrating a method for detecting optical anti-shake performance of a terminal device according to another embodiment of the disclosure.

As shown in fig. 6, the method for detecting optical anti-shake performance of the terminal device may include the following steps:

in step 601, when the terminal device is in the shooting mode, the movable device is controlled to drive the terminal device to move in an accelerating way.

Step 602, determining a first moving distance of the terminal equipment under the driving of the movable device.

The execution of steps 601 to 602 may refer to the execution of any embodiment of the present disclosure, and will not be described herein.

Step 603, determining whether the movement time of the terminal device is longer than the target time, if the movement time is longer than the target time, executing step 604, and if the movement time is not longer than the target time, executing step 605.

The target duration is determined according to the storage space and the sampling period of a driving register of the optical anti-shake device.

In the embodiment of the disclosure, the driving register of the optical anti-shake device may periodically collect movement data (or shake data) of the optical anti-shake device to obtain each storage value, and write each storage value into the driving register.

For example, if the sampling period of the flag driving register is T, the driving register periodically collects movement data (or jitter data) of the optical anti-shake device with T as a period, and writes the stored value sampled for each period into the driving register. I.e. the drive register generates a data packet (which includes values in the first direction and values in the second direction) every other period T.

In the embodiment of the disclosure, the target duration may be determined according to a storage space and a sampling period of a driving register of the optical anti-shake device.

As an example, assuming that the driving register may store at most m storage values (or data packets) according to the storage space of the driving register, that is, the storage space of the driving register is the size of m storage values (or data packets), the target duration may be m×t. For example, the storage space of the driving register is 12 data packets, the sampling period of the driving register is 2ms, and the target duration may be 24ms.

It should be noted that the above examples of the storage space and the sampling period of the driving register are only exemplary, and in practical application, the storage space and the sampling period of the driving register may be other values.

It should be noted that the storage spaces of the driving registers corresponding to the optical anti-shake devices of different models may be the same or may be different, which is not limited in the disclosure. And, the sampling periods of the driving registers corresponding to the optical anti-shake devices of different models may be the same or may be different, which is not limited in the disclosure.

In the embodiment of the present disclosure, after determining the movement duration of the terminal device, it may be determined whether the movement duration is greater than the target duration, if the movement duration is greater than the target duration, step 604 is performed, and if the movement duration is not greater than the target duration, step 605 is performed.

Step 604, when the movement time period is longer than the target time period, any one set of stored values in the driving register is acquired and used as a target value.

The stored value may include a value in a first direction and a value in a second direction, the value in the first direction may be used to indicate a shake distance of the optical anti-shake device in the first direction, the value in the second direction may be used to indicate a shake distance of the optical anti-shake device in the second direction, the first direction is perpendicular to the second direction, and the first direction and the second direction are perpendicular to a normal direction of a plane where a lens of the terminal device is located.

The explanation of the first direction and the second direction may also refer to the related description in any embodiment of the disclosure, which is not repeated herein.

Wherein the target value may be used to indicate a second movement distance of the optical anti-shake device.

In the embodiment of the present disclosure, when the movement time period is longer than the target time period, at this time, the drive register may cover a part of the stored values collected first in the shake process of the optical anti-shake device, and the difference between the uncovered stored values is small, so that any one set of stored values in the stored values may be obtained and used as the target value.

Step 605, when the movement duration is not greater than the target duration, the stored value stored in the drive register last time is obtained and used as the target value.

In the embodiment of the present disclosure, when the movement duration is not longer than the target duration, the driving register may completely store each storage value acquired during the dithering process of the optical anti-dithering apparatus, and at this time, the storage value stored in the driving register last time may be acquired and may be used as the target value.

Step 606, determining whether the anti-shake performance of the optical anti-shake device meets the set requirement according to the first moving distance and the target value.

The implementation of step 606 may refer to the implementation of any embodiment of the disclosure, which is not described herein.

The optical anti-shake performance detection method of the terminal equipment of the embodiment of the disclosure judges whether the moving duration is longer than the target duration, wherein the target duration is determined according to the storage space and the sampling period of the driving register; when the moving time length is longer than the target time length, any group of storage values in the driving register are obtained and used as target values; the storage value comprises a value in a first direction and a value in a second direction, wherein the value in the first direction is used for indicating the shaking distance of the optical anti-shaking device in the first direction, and the value in the second direction is used for indicating the shaking distance of the optical anti-shaking device in the second direction; and when the moving time is not longer than the target time, acquiring a stored value stored in the drive register last time and taking the stored value as a target value.
