All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The anti-shake photographing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 1 is a flowchart of an anti-shake photographing method according to an embodiment of the present application.

As shown in fig. 1, an anti-shake photographing method provided in an embodiment of the present application is applied to a mobile terminal, where the mobile terminal includes a scroll screen and a camera disposed on the scroll screen, and the anti-shake photographing method provided in an embodiment of the present application may include:

step 110: acquiring the jitter offset of the camera in the shooting process;

step 120: determining a compensation movement amount of the scroll screen according to the jitter offset, wherein the compensation movement amount is associated with the jitter offset;

step 130: and controlling the scroll screen to move according to the compensation movement amount so as to perform shake compensation on the camera.

It can be understood that the mobile terminal often shakes in the process of shooting by holding the mobile terminal by a user, and the shake of the mobile terminal drives the shake of a camera on the mobile terminal. In the embodiment of the application, in the case that the camera is stationary relative to the mobile terminal, since the shake offset of the mobile terminal during shooting can be understood as the shake offset of the camera during shooting, acquiring the shake offset of the camera during shooting may specifically be acquiring the shake offset of the mobile terminal during shooting.

In step 110, the embodiment of the present application does not specifically limit the manner of obtaining the jitter offset. For example, in the embodiment of the present application, the shake offset of the camera during shooting can be obtained by a sensor component such as an acceleration sensor and an angular velocity sensor. Of course, the jitter offset may also be obtained by other sensors, and the present application is not limited to this.

In this embodiment of the application, since the camera is disposed on the scroll screen, in step 120, for the mobile terminal disposed with the scroll screen, the movement of the scroll screen can drive the camera to move. On the basis of this, the compensating movement of the reel screen can actually also be understood as the compensating movement of the camera. That is to say, the scroll screen is controlled to move according to the compensation movement amount, and the camera is driven to move according to the compensation movement amount.

In step 120, the compensation movement amount is associated with the shake offset amount, and the compensation movement amount of the scroll screen may be determined according to the shake offset amount. For example, the direction of compensating the movement amount is opposite to the direction of the shake shift amount, or the direction of compensating the movement amount is away from the direction of the shake shift amount. The magnitude of the compensation movement amount is associated with the magnitude of the shake offset amount, for example, the magnitude of the compensation movement amount has a preset functional relationship with the magnitude of the shake offset amount. Thereby, the amount of compensation movement of the reel screen can be determined according to the shake offset amount.

In step 130, the scroll screen is controlled to move according to the compensation movement amount, and the movement of the scroll screen drives the camera to move, which is equivalent to driving the camera to move according to the compensation movement amount. The camera moves according to the compensation movement amount, the shake offset of the camera can be offset, and shake compensation is performed on the camera, so that a shot picture is clearer.

And, compare with optical type anti-shake mode among the correlation technique, because the removal space and/or the range of motion of spool screen itself are great relatively to the removal space and/or the range of motion that the removal of spool screen drove the removal of camera can be bigger, therefore, can solve the little technical problem of anti-shake range among the correlation technique to a certain extent.

In the anti-shake shooting method provided by the embodiment of the application, the shake offset of a camera in the shooting process is obtained; determining the compensation movement amount of the scroll screen according to the jitter offset, wherein the compensation movement amount is associated with the jitter offset; and controlling the scroll screen to move according to the compensation movement amount so as to perform shake compensation on the camera. Like this, at the in-process that the mobile terminal who utilizes to have the spool screen shoots, utilize the removal of spool screen itself to drive the camera and remove the shake that offsets the camera, compare with optical type anti-shake mode among the correlation technique, because the removal space and/or the range of motion of spool screen itself are great relatively, therefore, can solve the little technical problem of anti-shake range among the correlation technique to a certain extent.

In one particular embodiment, to maintain the relative stability of the camera, the amount of compensating movement of the scroll screen may be determined based on the amount of jitter offset. The determination of the compensated movement of the reel screen is illustrated below by way of example in fig. 2. Of course, the embodiment of the method shown in fig. 2 is only for illustration and is not meant to limit the application, and the embodiment of the application may also determine the compensated movement amount of the scroll screen through other specific embodiments.

Fig. 2 is a schematic flowchart of an anti-shake photographing method provided in an embodiment of the present application.

As shown in fig. 2, in an anti-shake photographing method provided in an embodiment of the present application, the step 120 may include:

step 210: multiplying the jitter offset by a preset conversion coefficient to obtain a first movement amount, wherein the preset conversion coefficient is a predetermined constant;

step 220: if the first movement amount is within a preset range, taking the first movement amount as the compensation movement amount;

step 230: if the first movement amount is out of the preset range, taking a preset movement amount as the compensation movement amount; wherein the preset movement amount is an upper limit value or a lower limit value of the preset range.

In step 210, the preset conversion coefficient may be a predetermined negative constant, and thus, the direction of the first shift amount and the direction of the shake offset amount may be opposite. For example, in the process of taking a picture or recording a video by a user holding the mobile terminal, the shake offset y of the camera is detected, and the shake offset y may be a vector and includes a direction of the shake offset. The scroll controller obtains a jitter offset y, and calculates a first movement z1 according to the jitter offset y, where the conversion formula may be z1 ═ - γ × y (- γ preset conversion coefficient, γ is a normal number smaller than 1).

In practical application, the value of γ can be obtained by pre-calculation, and the value of γ is associated with the precision and anti-shake level of a driving motor, and the driving motor is a motor for driving the scroll screen to move. For example, the larger the range of the preset range corresponding to the anti-shake level is, the larger the value of γ is.

In steps 220 and 230, the preset range may be a reasonable value range for compensating the movement amount, and the preset range may be different according to the anti-shake level. For example, shooting modes of the camera at different anti-shake levels (e.g., a reel anti-shake standard mode, a reel anti-shake super mode, etc.) may be set in advance; the preset range of the compensation movement amount in the reel anti-shake standard mode is predetermined as [ -a, a ], and the compensation range of the compensation movement amount in the reel anti-shake super mode is predetermined as [ -b, b ], wherein b > a > 0.

Based on this, for example, in the case where the user selects the reel anti-shake standard mode for shooting, if the first movement amount z1 is within the compensation amount range [ -a, a ] preset in the standard mode, the compensation movement amount z ═ z 1; if the first shift amount z1 is outside the standard mode preset compensation amount range [ -a, a ], the compensation shift amount z takes the upper limit value a or the lower limit value-a of the preset range according to the direction of the first shift amount z1, which is the same as the direction of the first shift amount z 1.

For another example, in a case where the user selects the scroll anti-shake super mode for photographing, if the first movement amount z1 is within a compensation amount range [ -b, b ] preset in the super mode, the compensation movement amount z is equal to z1, and if the first movement amount z1 is outside the compensation amount range [ -b, b ] preset in the super mode, the compensation movement amount z takes the upper limit value b or the lower limit value-b of the preset range according to the direction of the first movement amount z1, which is the same as the direction of the first movement amount z 1.

In the anti-shake photographing method provided by the embodiment of the application, the shake offset is multiplied by a preset conversion coefficient to obtain a first movement amount, wherein the preset conversion coefficient is a predetermined constant; if the first movement amount is within a preset range, taking the first movement amount as the compensation movement amount; if the first movement amount is out of the preset range, taking a preset movement amount as the compensation movement amount; wherein the preset movement amount is an upper limit value or a lower limit value of the preset range. Therefore, in the process of shooting by using the mobile terminal with the scroll screen, the compensation movement amount of the scroll screen is reasonably determined according to the shake offset of the camera and the preset range of the compensation movement amount, and the relative stability of the camera can be more accurately kept.

The camera is driven to move by the movement of the scroll screen, so that the shaking of the camera is counteracted. While the movement of the roller screen itself may include different types of movement, the roller screen itself may not only translate (e.g., extend or retract) but also rotate. Therefore, the moving directions of the scroll screen which is controlled to move according to the compensation moving amount can be different, and then the shaking of the camera in different directions can be flexibly counteracted. The following specifically exemplifies the anti-shake photographing method provided by the embodiment of the present application according to different movement types of the scroll screen.

Fig. 3 is a schematic flowchart of an anti-shake photographing method provided in an embodiment of the present application.

Taking the case that the movement of the scroll screen is the expansion of the scroll screen as an example, the mobile terminal may be provided with a driving motor which drives the scroll screen to expand. As shown in fig. 3, in a specific embodiment, an anti-shake photographing method provided by the embodiment of the present application may include:

step 310: acquiring the jitter offset of the camera in the shooting process, wherein the jitter offset has a first jitter direction parallel to the expansion direction of the scroll screen;

step 320: determining the compensation movement amount of the scroll screen according to the jitter offset; the compensation movement amount has a direction opposite to the first shake direction;

step 330: and controlling the scroll screen to move along the direction opposite to the first shaking direction according to the compensation movement amount so as to carry out shaking compensation on the camera.

Step 310 may be a sub-step of step 110; step 320 may be a substep of step 120; the above step 330 may be a sub-step of the step 130.

In step 310, since the jitter offset has a first jitter direction parallel to the expansion and contraction direction of the scroll screen, the unit of the jitter offset may be a length unit, such as centimeter, millimeter, etc. Specifically, the shake offset of the mobile terminal in the shooting process can be detected through the acceleration sensor, and the shake offset of the mobile terminal in the shooting process is used as the shake offset of the camera in the shooting process; the direction of the shake offset of the camera during shooting may be the same as or opposite to the direction of extension of the scroll screen. Of course, the jitter offset may also be obtained by other manners, and the present application is not limited in particular.

In step 320, the compensation movement amount has a direction opposite to the first shaking direction, and the specific manner of determining the magnitude of the compensation movement amount of the scroll screen may refer to the specific content of the method embodiment shown in fig. 2, but may be other manners, and is not described herein again.

In step 330, the scroll screen is controlled to move in a direction opposite to the first shaking direction according to the compensation movement amount so as to offset the shaking offset of the scroll screen, and the camera is subjected to shaking compensation. For example, under the condition that the first shaking direction of the shaking offset is the same as the extending direction of the scroll screen, the scroll screen is controlled to contract according to the specific length of the compensation movement amount in the shooting process so as to counteract the shaking of the camera; or, under the condition that the first shaking direction of the shaking offset is the same as the contraction direction of the scroll screen, controlling the scroll screen to stretch out according to the specific length of the compensation movement amount in the shooting process so as to counteract the shaking of the camera.

Fig. 4-1 and 4-2 are schematic structural diagrams of an anti-shake photographed picture provided by an embodiment of the present application. The anti-shake photographing method shown in fig. 3 will be described below by taking fig. 4-1 and 4-2 as an example.

As shown in fig. 4-1, fig. 4-1 presents a right side view and a front view, respectively, of the mobile terminal 10, the mobile terminal 10 including a scroll screen 101 and a camera 102 disposed on the scroll screen 101. Fig. 4-2 is a schematic interface diagram of the mobile terminal performing the jitter compensation process based on fig. 4-1, as shown in fig. 4-2, where the X direction is the stretching direction of the scroll screen, and the Y direction is a first jitter direction parallel to the stretching direction (X direction) of the scroll screen, where the jitter offset is measured; when the scroll screen 101 extends upwards, the camera can be driven to move upwards so as to offset the downward shaking offset of the camera; when the scroll screen 101 is retracted downward, the camera can be driven to move downward to offset the upward shake offset of the camera.

In practical applications, the user may select different anti-shake levels for shooting before step 310. The anti-shake level of the reel anti-shake standard mode and the reel anti-shake super mode is different. The shooting modes of the camera at different anti-shake levels (such as a standard mode and a super mode shown in fig. 4-1) can be preset; the preset range of the compensating movement amount in the reel anti-shake standard mode is predetermined as [ -a, a ], and the compensation range of the compensating movement amount in the reel anti-shake super mode is predetermined as [ -b, b ], wherein b > a > 0. Thus, after the reel anti-shake standard mode or super mode is selected, it is advantageous to determine the compensated movement amount of the reel screen according to the pass through shake offset amount and the preset range in step 320.

In the anti-shake shooting method provided by the embodiment of the application, the shake offset of the camera in the shooting process is obtained, wherein the shake offset has a first shake direction parallel to the telescopic direction of the scroll screen; determining a compensation movement amount of the scroll screen according to the shaking offset amount, wherein the compensation movement amount has a direction opposite to the first shaking direction; and controlling the scroll screen to move along the direction opposite to the first shaking direction according to the compensation movement amount so as to carry out shaking compensation on the camera. Therefore, in the process of shooting by using the mobile terminal with the scroll screen, the scroll screen is controlled to stretch and contract according to the compensation movement amount along the direction opposite to the first shaking direction by using the stretching characteristic of the scroll screen, so that the camera is driven to move to offset the shaking of the camera in the first shaking direction.

Fig. 5 is a schematic flowchart of another anti-shake photographing method provided in an embodiment of the present application.

Fig. 6-1 and 6-2 are schematic structural diagrams of an anti-shake photographing picture related to the anti-shake photographing method shown in fig. 5 provided in an embodiment of the present application.

Taking the example that the movement of the scroll screen is the rotation of the scroll screen, the scroll screen comprises a rotatable portion, and the camera is arranged on the rotatable portion of the scroll screen. As shown in fig. 6-1, fig. 6-1 presents a right side view and a front view of the mobile terminal 10, respectively, the mobile terminal 10 may further include a hinge 103, the hinge 103 divides the scroll screen 101 into a rotatable portion 1011 and a non-rotatable portion 1012, the camera 102 is disposed on the rotatable portion 1011 of the scroll screen 101, and the driving motor drives the hinge 103 to rotate, so as to drive the rotatable portion of the scroll screen and the camera to rotate. Specifically, fig. 6-2 is a schematic interface diagram of the mobile terminal performing the shake compensation process based on fig. 6-1, and as shown in fig. 6-1 and fig. 6-2, when the hinge 103 rotates clockwise as viewed in the front view of the mobile terminal 10, the rotatable portion of the scroll screen and the camera are driven to rotate backward; when the hinge 103 rotates counterclockwise, the rotatable part of the scroll screen and the camera can be driven to rotate forward. Of course, the rotation mode of the rotatable scroll screen can also be realized by other modes, and the application is not particularly limited.

As shown in fig. 5, in another specific embodiment, an anti-shake photographing method according to an embodiment of the present application may include:

step 510: acquiring the shake offset of the camera in the shooting process, wherein the shake offset has a second shake direction associated with the rotation direction of the scroll screen;

step 520: determining the compensation movement amount of the scroll screen according to the jitter offset; the compensation movement amount has a direction deviating from the second shake direction;

step 530: and controlling the rotatable part of the scroll screen to rotate along the direction deviating from the second shaking direction according to the size of the compensation movement amount so as to carry out shaking compensation on the camera.

Step 510 may be a sub-step of step 110; step 520 may be a sub-step of step 120; step 530 described above may be a sub-step of step 130.

In step 510, the unit of the dither offset may be an angular unit, such as degrees, etc., since the dither offset has a second dither direction associated with the rotational direction of the spool screen. Specifically, the shake offset of the mobile terminal in the shooting process can be detected through the angular velocity sensor, and the shake offset of the mobile terminal in the shooting process is used as the shake offset of the camera in the shooting process; the second shake direction of the shake offset of the camera in the shooting process can be deviated from the rotation direction of the scroll screen. Of course, the jitter offset may also be obtained by other manners, and the present application is not limited in particular.

In step 520, the compensation movement amount has a direction deviating from the second shaking direction, and the specific manner of determining the magnitude of the compensation movement amount of the scroll screen may refer to the specific content of the method embodiment shown in fig. 2, but may be other manners, which is not described herein again.

In step 530, the scroll screen is controlled to rotate in a direction away from the second shaking direction according to the compensation movement amount to offset the shaking offset of the scroll screen, so as to perform shaking compensation on the camera. Wherein the direction that is away from the second dither direction of the dither offset may include a direction that is opposite to the second dither direction of the dither offset. For example, taking fig. 6-2 as an example, in the case that the second shake direction of the shake offset amount is forward shake, the scroll screen is controlled to rotate backward by a specific angle compensating the movement amount during shooting to counteract shake of the camera; or, in the case that the second shaking direction of the shaking offset is backward shaking, the scroll screen is controlled to rotate forward according to the specific angle of the compensation movement amount during shooting so as to counteract shaking of the camera.

In the anti-shake shooting method provided by the embodiment of the application, a shake offset of the camera in the shooting process is obtained, wherein the shake offset has a second shake direction associated with the rotation direction of the scroll screen; determining a compensation movement amount of the scroll screen according to the jitter offset, wherein the compensation movement amount has a direction deviating from the second jitter direction; and controlling the scroll screen to rotate according to the compensation movement amount along the direction deviating from the second shaking direction so as to carry out shaking compensation on the camera. Therefore, in the process of shooting by using the mobile terminal with the scroll screen, the scroll screen is controlled to rotate according to the compensation movement amount, so that the camera is driven to move back and forth to offset the shake of the camera in the second shake direction.

Fig. 7 is a schematic flowchart of an anti-shake photographing method provided in an embodiment of the present application.

Of course, the movement of the scroll screen may also be a compound movement including linear movement and rotation, as shown in fig. 7, in another specific embodiment, the scroll screen is a rotatable scroll screen, the scroll screen includes a rotatable portion and a non-rotatable portion, and the camera is disposed on the rotatable portion of the scroll screen, and the embodiment of the present application provides an anti-shake photographing method, which may include:

step 710: acquiring the jitter offset of the camera in the shooting process; the shake offset amount includes a first shake offset amount having a first shake direction parallel to a telescopic direction of the spool screen and a second shake offset amount having a second shake direction associated with a rotational direction of the spool screen;

step 720: determining a first compensation movement amount of the scroll screen according to the first jitter offset; determining a second compensation movement amount of the scroll screen according to the second jitter offset; the first compensation movement amount has a direction opposite to the first shake direction, and the second compensation movement amount has a direction away from the second shake direction;

step 730: controlling the rotatable part of the scroll screen to rotate along the direction deviating from the second shaking direction according to the second compensation movement amount; and controlling the non-rotatable part of the scroll screen to linearly move along the direction opposite to the first shaking direction according to the first compensation movement amount so as to perform shaking compensation on the camera.

Step 710 may be a sub-step of step 110; step 720 may be a substep of step 120; step 730 described above may be a sub-step of step 130.

In step 710, the jitter offset includes a first jitter offset and a second jitter offset.

The first shaking offset has a first shaking direction parallel to the expansion direction of the scroll screen, and the unit of the first shaking offset may be a length unit, such as centimeter, millimeter, and the like. Specifically, a first shake offset of the mobile terminal in the shooting process can be detected through the acceleration sensor, and the first shake offset of the mobile terminal in the shooting process is used as the first shake offset of the camera in the shooting process; the direction of the first shake offset of the camera in the shooting process can be parallel to the telescopic direction of the scroll screen.

Wherein the second dither offset has a second dither direction associated with the rotational direction of the spool screen, and the unit of the second dither offset may be an angular unit, such as degrees or the like. Specifically, a second shake offset of the mobile terminal in the shooting process can be detected through the angular velocity sensor, and the second shake offset of the mobile terminal in the shooting process is used as a second shake offset of the camera in the shooting process; the second shake direction of the second shake offset of the camera in the shooting process can deviate from the rotation direction of the scroll screen. Of course, the jitter offset may also be obtained by other manners, and the present application is not limited in particular.

In step 720, the first compensating movement amount may have a direction opposite to the first shaking direction, the second compensating movement amount may have a direction away from the second shaking direction, and the specific manner of determining the magnitude of the first compensating movement amount and the magnitude of the second compensating movement amount of the scroll screen may refer to the specific contents of the method embodiment shown in fig. 2. Further description is provided below by way of example.

In the embodiment of the present application, the specific implementation manner of determining the first compensation movement amount may include:

multiplying the first jitter offset component by a first preset conversion coefficient to obtain a first movement amount, wherein the first preset conversion coefficient is a negative constant predetermined according to the actual jitter elimination condition; if the first movement amount is within a first preset range, taking the first movement amount as a first compensation movement amount; if the first movement amount is out of the first preset range, taking the first preset movement amount as a first compensation movement amount; the first preset movement amount is an upper limit value or a lower limit value of the first preset range.

Similarly, in the embodiment of the present application, a specific implementation manner of determining the second compensation movement amount may include:

multiplying the second jitter offset component by a second preset conversion coefficient to obtain a second movement amount, wherein the second preset conversion coefficient is a negative constant predetermined according to the actual jitter elimination condition; if the second movement amount is within a second preset range, taking the second movement amount as a second compensation movement amount; if the second movement amount is out of the second preset range, taking the second preset movement amount as a second compensation movement amount; and the second preset movement amount is an upper limit value or a lower limit value of the second preset range. Specific examples are described below.

In practical application, during the process of taking a picture or recording a video by holding the mobile terminal by a user, recording a first jitter offset component y of jitter of the mobile terminal, where the first jitter offset component y may be a vector and includes a direction (up or down) of the first jitter offset component, and the reel controller obtains the first jitter offset component y and converts the first jitter offset component y into a first movement amount z1 by calculating, where the conversion formula may be z1 ═ γ × y (- γ first preset conversion coefficient, and γ is a normal number). Meanwhile, in the process of photographing or video recording by holding the mobile terminal by a user, recording a second jitter offset component m of the jitter of the mobile terminal, wherein the second jitter offset component m is a vector and comprises the direction (forward or backward) of the second jitter offset component, the scroll controller acquires the second jitter offset component m and converts the second jitter offset component m into a second movement amount q1 through calculation, and the conversion formula can be q1 ═ β × m (- β second preset conversion coefficient, β is a normal number).

On the basis of this, it is determined whether the first shift amount z1 and the second shift amount q1 are within a reasonable range of the compensation shift amount. The first movement z1 can be [ -a, a ], [ -b, b ], and b > a >0 in the preset reel anti-shake standard mode and the preset reel anti-shake super mode, respectively. The second predetermined compensation ranges of the second moving amount q1 in the preset reel anti-shake standard mode and the preset reel anti-shake super mode are [ -c, c ], [ -d, d ], and d > c >0, respectively.

Based on this, in the case where the user selects the reel anti-shake standard mode for photographing, if the first moving amount z1 is within the compensation amount range [ -a, a ] preset in the standard mode, the first compensation moving amount is z 1; if the first moving amount z1 is outside the compensation amount range [ -a, a ] preset in the standard mode, the first compensation moving amount z takes the upper limit value a or the lower limit value-a of the preset range according to the direction of the first moving amount z1, which is the same as the direction of the first moving amount z 1. Similarly, if the second movement amount q1 is within the standard mode preset compensation amount range [ -c, c ], the second compensation movement amount is q 1; if the second moving amount q1 is outside the compensation amount range [ -c, c ] preset in the standard mode, the second compensation moving amount q takes the upper limit value c or the lower limit value-c of the preset range according to the direction of the second moving amount q1, which is the same as the direction of the second moving amount q 1.

For another example, in the case where the user selects the reel anti-shake super mode for photographing, if the first moving amount z1 is within the compensation amount range [ -b, b ] preset in the super mode, the first compensation moving amount is z 1; if the first shift amount z1 is outside the super mode preset compensation amount range [ -b, b ], the first compensation shift amount z takes the upper limit value b or the lower limit value-b of the preset range according to the direction of the first shift amount z1, which is the same as the direction of the first shift amount z 1. Similarly, if the second movement amount q1 is within the super-mode preset compensation amount range [ -d, d ], the second compensation movement amount is q 1; if the second moving amount q1 is outside the super mode preset compensation amount range [ -d, d ], the second compensation moving amount q takes the upper limit value d or the lower limit value-d of the preset range according to the direction of the second moving amount q1, wherein the direction of the second compensation moving amount q is the same as the direction of the second moving amount q 1.

In step 730, the order of controlling the parallel movement and rotation of the spool screen is not particularly limited.

For example, in the embodiment of the present application, the scroll screen may be controlled to rotate according to the second compensation movement amount in a direction away from the second shaking direction of the second shaking offset amount; and then controlling the scroll screen to move along the direction opposite to the first shaking direction of the first shaking offset according to the first compensation movement amount.

For another example, in the embodiment of the present application, the scroll screen may be simultaneously controlled to rotate in a direction away from the second shaking direction of the second shaking offset amount according to the second compensation movement amount; and controlling the scroll screen to move in a direction opposite to the first shaking direction of the first shaking offset amount according to the first compensation movement amount. The present application is not particularly limited.

In step 730, since the rotatable portion of the scroll screen and the non-rotatable portion of the scroll screen both have the same expansion and contraction characteristics, the non-rotatable portion of the scroll screen is controlled to move linearly in a direction opposite to the first shaking direction, which is understood to mean that the linear movement of the non-rotatable portion drives the rotatable portion of the scroll screen to move linearly in the same direction as the non-rotatable portion; and then drive the camera to make the same linear movement as the non-rotatable part. Here, the linear movement refers to a linear movement in a specific direction (i.e., a direction opposite to the first shake direction of the first shake offset amount). The specific scroll screen control method may refer to step 330 and step 530, and the interface schematic diagram of the anti-shake photographed image may also refer to fig. 4-2 and fig. 6-2, which are not described herein again.

In this way, in the process of shooting by using the mobile terminal with the scroll screen, the scroll screen is controlled to extend, retract and rotate according to the compensation movement amount by using the extension and retraction characteristic and the rotation characteristic of the scroll screen, so that the camera is driven to move to extend, retract and rotate, and the shake of the camera in a first shake direction (for example, the up-down extension direction) and a second shake direction (for example, the front-back direction) is counteracted.
