Detailed Description

Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

In the shooting process, a user generally directly holds the imaging device, or installs and fixes the imaging device on a selfie stick or other devices, and holds the selfie stick or other devices. Because the user moves and/or the poor stability of equipment such as a selfie stick exists, the imaging image often shakes, so that the phenomena of distortion, distortion and the like exist in the shot picture or image, and the imaging quality is not ideal enough. And when additionally adding image stabilization equipment on equipment such as a selfie stick, the volume of the equipment such as the selfie stick is greatly increased easily, and the carrying of a user is inconvenient.

According to an exemplary embodiment of the present disclosure, a portable image stabilization device is presented. As shown in fig. 1 to 4, fig. 1 shows a schematic configuration of a portable image stabilization apparatus 100, fig. 2 shows a schematic configuration of a portable image stabilization apparatus 100 in a storage state, fig. 3 shows an expanded schematic configuration of the portable image stabilization apparatus 100, and fig. 4 shows a schematic configuration of a holder of the portable image stabilization apparatus 100 at another rotation angle. The portable image stabilization device 100 comprises a first arm 110, a second arm 120 and a connecting member 130 rotatably connecting the first arm 110 and the second arm 120. The first arm 110 can rotate relative to the second arm 120 by the connecting member 130. Typically, during use of the portable image stabilization device 100, the first arm 110 may be opened with respect to the second arm 120 by the connector 130 and maintained at an angle for photographing; when the portable image stabilization device 100 is not in use, the first arm 110 can be closed relative to the second arm 120 by the connecting member 130, thereby reducing the space occupied by the portable image stabilization device 100 and facilitating carrying or storage.

As shown in fig. 1, 3 and 4, first arm 110 includes a clamp 112, clamp 112 being used to fixedly mount the imaging device on portable image stabilization device 100. The clamping member 112 may specifically include a supporting portion 112b and a clamping claw 112a, wherein a surface of the supporting portion 112b may contact with a back surface of the image forming apparatus, so as to form a certain support for the image forming apparatus and better stabilize the image forming apparatus. The clamping claws 112a may be provided at the side of the bearing portion 112b, and accordingly, when the image forming apparatus is mounted on the clamping member 112, it is clamped at the side by the clamping claws 112a to be fixed to prevent the image forming apparatus from falling off the portable image stabilizing apparatus 100. Further, a plurality of sets of clamping claws 112a may be provided in the clamp 112, thereby increasing the force acting between the image forming apparatus and the portable image stabilizing apparatus 100, further improving the reliability of clamping. In the clamp 112 shown in fig. 1, a total of four clamping claws 112a are provided at positions near four corners of the receiver 112b, respectively, to secure the mounting reliability of the image forming apparatus. The free end of the clamping jaw 112a may further include a clamping button 112d bent toward the supporting portion 112b, and the clamping button 112d may have a certain elasticity, so that when the image forming apparatus is clamped by the clamping member 112, the clamping button 112d may help to increase an acting force between the image forming apparatus and the clamping jaw 112, so that the image forming apparatus is reliably connected to the clamping member 112, and the image forming apparatus is prevented from moving relative to the clamping member 112, which may help to improve the reliability of clamping and prevent the image forming apparatus from falling off, and on the other hand, the posture of the image forming apparatus may be well controlled by controlling the position of the clamping member.

Further, as shown in fig. 3 and 4, the clamping member 112 may further include an elastic portion 112c, and the elastic portion 112c may be formed by one or more springs or rods. When the image forming apparatus is clamped, the elastic portion 112c is stretched to form a clamping space in which the image forming apparatus is placed, and when the elastic portion 112c is released again, the image forming apparatus will be fixed by the elastic force of the elastic portion 112c, so that the image forming apparatus can stably follow the movement of the clamp 112 to adjust the posture of the image forming apparatus by adjusting the position of the clamp 112.

As shown in fig. 3, first arm 110 further includes an image stabilization drive motor 113, and image stabilization drive motor 113 is coupled to clamp 112 to drive clamp 112. Specifically, the image stabilizing driving motor 113 may be directly connected to the clamping member 112 through a driving shaft thereof, and the clamping member 112 is driven to rotate by rotation of the driving shaft, so that the imaging device fixedly mounted on the clamping member 112 has a suitable imaging posture or imaging position. Alternatively, the image stabilizing driving motor 113 may be indirectly connected to the clamping member 112 through a transmission component including a gear, and the like, and the clamping member 112 is driven by the driving shaft and the transmission component to rotate, so as to enable the imaging device on the clamping member 112 to be in a proper imaging posture or imaging position. It can be understood that the image stabilizing driving motor 113 can not only drive the clamping member 112 to rotate in a single axis, but also be configured to drive the clamping member 112 to translate within a certain range, so as to adjust the posture or position of the imaging device better and improve the imaging effect.

The maximum rotation angle of the clamping member 112 may be any angle between 0 to 360 degrees, so that the stability of the image forming apparatus is maintained within the range of the maximum rotation angle, and the image forming quality is improved. However, to further improve the user experience, the clamp 112 may be configured to rotate continuously, i.e. with a maximum rotation angle of more than 360 degrees, under the drive of the image stabilization drive motor 113. The continuously rotatable clamp 112 is not restricted to a certain fixed rotational direction. The continuously rotatable clamping member 112 can drive the imaging device to rotate freely on one hand, and on the other hand, can help to select the most efficient rotation path by changing the rotation direction, so as to improve the image stabilizing effect, and especially in the process of capturing, the image stabilizing is fast and efficient, and the influence on the imaging quality is great.

In order to support the clamping member 112 and the image stabilizing driving motor 113, the first arm 110 may further include a first body 111, and the clamping member 112 and the image stabilizing driving motor 113 are both mounted on the first body 111. The first body 111 may be made of metal, plastic, etc., and may be made of a light material as much as possible while ensuring the reliability of the support. The first body 111 also contributes to improving the structural stability of the first arm 110 as a whole, thereby reducing image shaking and the like.

The second arm 120 of the portable image stabilization device 100 comprises a second body 121 and a control assembly, which may be arranged on the second body 121. Wherein at least a portion of the second body 121 forms a grip 123, and a user can conveniently carry the portable image stabilization device 100 through the grip 123. The grip portion 123 may be disposed at an end of the second arm 120 away from the connecting member 130 to increase a movable range of the clamping member 112 of the first arm 110 with respect to the grip portion 123, that is, a movable range of the image forming apparatus with respect to a user is correspondingly increased, so as to achieve a more free image forming effect. The outer surface of the holding part 123 can be provided with rough grains to increase friction force, facilitate holding and improve holding experience of a user. Meanwhile, a control assembly 124 such as a key, a touch screen, etc. may be further disposed on the surface of the holding portion 123, so as to realize interaction between the user and the portable image stabilization device 100, and facilitate the user to operate the imaging device through the control assembly 124. The control component 124 is electrically connected with the control component, and controls the position of the clamping member 112 through the control component, so that the imaging device connected to the clamping member 112 maintains a required posture to meet the imaging requirement.

A receiving groove 122 is further formed on the second body 121, and the receiving groove 122 can receive the first arm 110 in a receiving state, so as to store and carry the portable image stabilizing apparatus 100. As shown in fig. 1, 3 and 4, a receiving groove 122 may be opened on a portion of the second body 121 between the grip 123 and the connecting member 130, the length of the first arm 110 is generally shorter than that of the second arm 120, and the length of the first arm 110 corresponds to that of the receiving groove 122. As shown in fig. 2, in the storage state, the first arm 110 rotates to a position embedded in the receiving groove 122, an included angle between the first arm 110 and the second arm 120 is substantially zero, and an outer surface of the first arm 110 is substantially flush with an outer surface of the second arm 120, so that the portable image stabilizing apparatus 100 has a simple and beautiful appearance.

Further, in the accommodated state, the clamping claws 112a of the clamping member 112 can also be fitted in the accommodation grooves 122, thereby facilitating carrying and storage of the portable image stabilization apparatus 100. As shown in fig. 1 and 2, since the clamping claws 112a are generally disposed at the side edges of the clamping member 112, correspondingly, the clamping claws 112a are also located at the side edges of the receiving groove 122 in the receiving state and are arranged in a staggered manner with other components or assemblies, such as the telescopic member 126, in the receiving groove 122, so as to avoid interference between different components or assemblies.

As described above, the control assembly may be directly disposed in the receiving groove 122, or the control assembly may be disposed in a first receiving cavity separately formed on the second body 121. The first accommodating cavity can be communicated with the accommodating groove 122 to reduce the process difficulty; alternatively, the first receiving cavity may be isolated from the receiving cavity 122, so as to avoid interference between the first arm 110 and the control assembly, and prolong the service life of the portable image stabilization device 100. The control assembly may be disposed corresponding to the position of the holding portion 123, that is, the first accommodating cavity is disposed inside the holding portion 123, so as to fully utilize the space of the second arm 120 and reduce the volume of the portable image stabilization device 100. Alternatively, the control assembly may be disposed adjacent to the connecting member 130 to reduce the distance between the control assembly and the image stabilizing drive motor 113, thereby facilitating the electrical connection between the control assembly and the image stabilizing drive motor 113 and controlling the operation of the image stabilizing drive motor 113.

As shown in fig. 3 to 7, since the image stabilizing drive motor 113 is provided in the first arm 110 and the control and power supply components are provided in the second arm 120, and there is an electrical connection between the image stabilizing drive motor 113 and the control and power supply components to achieve signal transmission and control, it is necessary to secure connection reliability by arranging the cable 132 appropriately. Since the first arm 110 is relatively rotatable with respect to the second arm 120, during the rotation process, the shape of the cable 132 connected between the first arm 110 and the second arm 120 may be changed, and the cable 132 may be squeezed, which may cause a safety hazard and affect the operation of the device.

In an exemplary embodiment, as shown in fig. 3, 5 and 6, image stabilization drive motor 113 is connected to the control assembly by a cable 132 that extends through receiving slot 122 and connector 130. The power supply assembly may also be electrically connected directly to the control assembly in the second arm, and the power supply assembly may be electrically connected to the image stabilization drive motor 113 because the control assembly may be electrically connected to the image stabilization drive motor 113. Wherein, the first end 132a of the cable 132 is fixed at one end of the first arm 110 close to the connecting member 130, or the first end 132a of the cable 132 is fixed at one end of the second arm 120 close to the connecting member 130, and the second end 132b of the cable 132 elastically stretches and contracts to maintain the tension state. That is, during rotation of the first arm 110 relative to the second arm 120, the cable 130 connected between the control assembly and the portable image stabilization device 100 is always under tension, and thus, there is no tendency for an excessively long cable 132 to accumulate between the first arm 110 and the second arm 120, thereby preventing the cable 132 from being pinched.

In another exemplary embodiment, as shown in fig. 7 and 8, the cable 132 is covered by the first body 111 of the first arm 110 or the second body 121 of the second arm 120. By providing the first body 111 or the second body (not shown in the drawings) capable of covering the cable 132, the cable 132 can be protected from being exposed to the outside, thereby contributing to extension of the life of the portable image stabilization apparatus 100.

In yet another exemplary embodiment, as shown in fig. 9 and 10, the connection member 130 may include a damping shaft 131, and the cable 132 is disposed through the damping shaft 131 such that the length of the cable 132 is always maintained during the rotation of the damping shaft 131, thereby preventing the cable 132 from being compressed. The damping shaft 131 may be an existing finished shaft, and may include a first portion and a second portion made of a material with a large friction force, such as rubber, and the friction force between the first portion and the second portion may make the damping shaft 131 stay at any angle within a rotation range, thereby helping to stabilize an included angle between the first arm and the second arm.

In an exemplary embodiment of the present disclosure, in order to adjust the position of the clamp 112 in a targeted manner while improving the efficiency of adjustment of the position of the clamp 112, the portable image stabilization device 100 may further include a position sensor. The position sensor is coupled to an image stabilization drive motor 113. Specifically, the position sensor may be directly electrically connected to the image stabilization driving motor 113. Or, the position sensor can acquire position information through optical sensing and other modes, is electrically connected with the control assembly, transmits the position information to the image stabilizing driving motor 113 through the control assembly, and adjusts the position of the clamping member 112 in real time, so that the imaging device connected to the clamping member 112 is always stabilized at a preset angle. In some specific examples, the preset angle corresponds to an angle at which the image forming apparatus is held in a horizontal plane, or an angle at which the image forming apparatus is held in a vertical direction, or an arbitrary angle set by a user, thereby improving image quality.

Further, the position sensor may include a first position sensor and a second position sensor. Wherein the first position sensor is for sensing a pose of the imaging device. For example, the first position sensor may include an Inertial Measurement Unit (IMU) to acquire the three-axis attitude angle (or angular rate) and acceleration of the imaging device. In general, the inertial measurement unit includes three single-axis accelerometers and three single-axis gyroscopes, the accelerometers detect acceleration signals of the imaging device in three independent axes in the carrier coordinate system, and the gyroscopes detect angular velocity signals of the carrier relative to the navigation coordinate system, so as to determine the angular velocity and acceleration of the imaging device in three-dimensional space and to solve the attitude thereof. Alternatively, the first position sensor may obtain the posture of the imaging device by reading corresponding data of a position sensor provided in the imaging device.

The second position sensor is used for sensing the rotation angle of the clamp 112. Specifically, the second position sensor may be a hall device, a magnetic deflection device, a potentiometer, or the like. The second position sensor determines the rotation angle of the clamp 112 by acquiring the relevant electrical parameter of the image-stabilizing drive motor 113. Further, in the image stabilization process, the control assembly can calculate the driving amount to be given by the image stabilization driving motor 113 according to the current posture of the imaging device and the current rotation angle of the clamping piece 112, so that the position of the clamping piece 112 is adjusted, the imaging device connected to the clamping piece 112 is stabilized at a preset angle, and the imaging quality is guaranteed.

In another exemplary embodiment of the present disclosure, the clamp 112 may also be adjusted according to a user instruction, so that the posture of the imaging apparatus mounted on the clamp 112 is conformed to the user's special needs, so that the user can freely take a photograph. Specifically, the user may send a user command to the control component through the control component 114 or the remote controller 140 on the grip 123, and the image stabilizing driving motor 113 adjusts the position of the holder 112 according to the received user command from the control component.

In the process of adjusting the position of the clamping member 112, the acceleration of the clamping member 112 in the rotating or translating process can be controlled through a user instruction or preset adjusting parameters, so that the stable transition of the position of the clamping member 112 is realized, the transient current and the shaking degree of the image stabilizing driving motor 113 are reduced, and the stability of the imaging device is guaranteed.

In the above embodiment, as shown in fig. 3, the second arm 120 of the portable imaging device further includes a power supply component. The power supply assembly may be provided inside the grip portion 123 to maintain the appearance of the portable imaging apparatus neat and beautiful. The power supply module may be disposed in the accommodating groove 122 or the first accommodating cavity together with the control module, or a second accommodating cavity may be additionally formed on the second body 121 for the power supply module, and the power supply module may be disposed in the second accommodating cavity. The second accommodating cavity can be communicated with the first accommodating cavity and/or the accommodating groove 122, so that the process difficulty is reduced; or may be provided separately to avoid interference between the power supply and the control assembly or the power supply and the first arm 110. The power supply assembly may also be located adjacent to image stabilization drive motor 113 to facilitate electrical connection to image stabilization drive motor 113. The power supply assembly supplies power to the image stabilization drive motor 113, although the power supply assembly may supply power to other related components or assemblies, such as the control assembly in the portable image stabilization device 100.

In a specific example, as shown in fig. 1, 3 and 4, the power supply component includes a lithium battery and a USB interface 125. The lithium battery has the advantages of high energy density, light structure, long service life, high safety and the like, and is suitable for being used as a power supply of the portable image stabilization device 100. In addition, the lithium battery can be charged through the USB interface 125 to realize recycling. Also, the lithium battery may supply power to an external imaging device or other devices through the USB interface 125, thereby extending the endurance time of the imaging device, or using the portable image stabilization device 100 as a power source in a case of emergency or the like.

In the above embodiment, as shown in fig. 1, 3 and 4, the portable image stabilizing apparatus 100 further includes an expansion piece 126, the expansion piece 126 may be in a rod shape, i.e. an expansion rod, and the expansion piece 126 is accommodated in the accommodating groove 122, the expansion piece 126 is connected to the first arm 110 and can extend and retract through a through hole formed in the second body, so as to change the expansion state of the first arm 110 relative to the second arm 120, so that the distance between the imaging apparatus connected to the clamping piece 112 and the user is changed, and the user can freely complete shooting according to the requirement.

Further, as shown in fig. 1, fig. 3 and fig. 4, the portable image stabilization device 100 may further include a remote controller 140, where the remote controller 140 may establish a direct wireless communication connection with the imaging device through a bluetooth signal, an infrared signal, a Wi-Fi signal, or the like, or establish a direct wireless communication connection with the control component, and then establish an indirect connection with the imaging device through the control component, so as to control the shutter of the imaging device, thereby facilitating the operation of a user. The remote controller 140 may be embedded in the receiving groove 122 for use or may be taken out from the receiving groove 122 for separate use, thereby expanding the applicable scenes of the portable image stabilization apparatus 100. For example, the user may fix the portable image stabilization apparatus 100, in which the imaging apparatus is installed, at a remote place and control the opening and closing of the shutter of the imaging apparatus through the remote controller 140. Preferably, when the portable image stabilization apparatus 100 is not in use, the remote controller 140 may be received in the receiving groove 122 of the second arm 120 and covered on the inside by the first arm 110 that is turned on, so as to prevent the remote controller 140 from being lost.

In the above embodiment of the present disclosure, as shown in fig. 1, 3 and 4, a tripod interface 127 is further opened at one end of the second body 121 far from the connecting piece 130. The tripod interface 127 may facilitate attachment of the portable image stabilization device 100 to another tripod, thereby achieving better imaging results.

According to an embodiment of the present disclosure, there is also provided an image stabilization system 200, as shown in fig. 11, including: a power module 210, a driver module 220, and a control module 230. The power module 210 includes a battery and a power management circuit, and the power management circuit can control the battery to supply power to the driving module 220, the control module 230, and/or other external devices, and can also charge the battery. The driving module 220 may include an image stabilizing driving motor and corresponding driving components, etc., and the control module 230 may include a control component electrically connected to the driving components, etc., in the exemplary embodiment shown in fig. 11, the control module 230 and the driving module 220 may be co-located, and the control module 230 controls the driving module 220 to adjust the position of the driving module 220.

Further, the image stabilization system 220 further includes a sensing module 240 to adjust the posture of the imaging device, so as to improve the imaging effect. The sensing module 240 may specifically include a first position sensor and a second position sensor. Wherein the first position sensor is for sensing a pose of the imaging device. For example, the first position sensor may include an Inertial Measurement Unit (IMU) to acquire the three-axis attitude angle (or angular rate) and acceleration of the imaging device. Alternatively, the first position sensor may obtain the posture of the imaging device by reading corresponding data of a position sensor provided in the imaging device. The second position sensor is used to sense the position and posture of the driving module 220. Specifically, the second position sensor may be a hall device, a magnetic deflection device, a potentiometer, or the like. The second position sensor determines the rotation angle by acquiring the relevant electrical parameters of the image stabilizing driving motor in the driving module 220, and the like.
