CROSS REFERENCE TO RELATED DISCLOSURE 
     This application claims the priority benefit of China Patent Application Number 202111303408.2, filed on Nov. 05, 2021, the full disclosure of which is incorporated herein by reference. 
     BACKGROUND 
     Technical Field 
     The present disclosure is related to a camera device, and in particular, a camera device with five-axis compensation. 
     Related Art 
     The camera device usually has an anti-shake mechanism used to reduce the user’s shake during the shooting process, in order to let the users obtain images of good quality. The current camera device may compensate for the vibration of the four axes. More specifically, the four axes refer to linear movement in the X-axis or Y-axis direction orthogonal to the optical axis of the camera lens, rotation with the X-axis as the axis (pitch), and rotation with the Y-axis as the axis (yaw). However, the compensation angle of the current anti-shake mechanism may only be within plus and minus 1.5 degrees, therefore the scope of application of the anti-shake mechanism is small. In addition, for the direction parallel to the optical axis of the camera lens (ie, the Z-axis), the current camera device still may not compensate for the rotation with the Z-axis as the axis (roll). Furthermore, the camera device needs to be provided with a rotating structure and rotating shaft corresponding to the anti-shake compensation function of each axis, which increases the overall complexity and cost. Therefore, how to provide a camera device with five-axis compensation has become an urgent issue to be solved in the art. 
     SUMMARY 
     The embodiments of the present disclosure disclose a camera device, in order to solve the problem that the optical compensation angle of the camera device is small and the camera device only has four-axis compensation in the prior art. 
     In order to solve the above technical problems, the present disclosure is implemented as follows. 
     A camera device is provided, which includes a first frame, a second frame, a camera component, and a driving component comprising a plurality of magnets and a plurality of coils. The first frame includes a first arc surface, and the first arc surface is on an inner surface of the first frame and recesses inward to form a circular arc shape. The second frame is movably disposed in the first frame and includes a second arc surface, and the second arc surface is on an outer surface of the second frame and protrudes outward to form a circular arc shape. The first arc surface and the second arc surface are matched with each other. The camera component is disposed in the second frame. The magnets and the coils are disposed on the first frame and the second frame, and the coils are configured to be cooperated with the magnets to drive the second frame to rotate with the first direction, the second direction, and the third direction as axes. The first direction, the second direction, and the third direction are perpendicular to one another, and the third direction is parallel to an optical axis of the camera component. When the second frame rotates with the first direction, the second direction, and/or the third direction as the axes, the first arc surface and the second arc surface move relative to each other. 
     In some embodiments, the circular arc shape of the first arc surface and the circular arc shape of the second arc surface are concentric circles. 
     In some embodiments, a part of the magnets and the coils of the driving component forms a first driving component, and the first driving component includes a first magnet, a first coil, a second magnet, and a second coil. The first magnet is disposed on the second frame. The first coil is disposed on the first frame and corresponding to the first magnet, and the first coil is configured to interact with the first magnet to drive the second frame to rotate with the first direction as an axis. The second magnet is disposed on the second frame. The second coil is disposed on the first frame and corresponding to the second magnet, and the second coil is configured to interact with the second magnet to drive the second frame to rotate with the second direction as an axis. 
     In some embodiments, a part of the magnets and the coils of the driving component forms a second driving component, and the second driving component includes a third magnet, a third coil, a fourth magnet, and a fourth coil. The third magnet is disposed on the second frame. The third coil is disposed on the first frame and corresponding to the third magnet, and the third coil is configured to interact with the third magnet to drive the second frame to positively rotate with the third direction as an axis. The fourth magnet is disposed on the second frame. The fourth coil is disposed on the first frame and corresponding to the fourth magnet, and the fourth coil is configured to interact with the fourth magnet to drive the second frame to oppositely rotate with the third direction as an axis. 
     In some embodiments, the camera device further includes a first circuit component. The first circuit component is movably disposed on the first frame and includes a first flexible circuit board surrounding the first frame and a first connector disposed at one end of the first flexible circuit board, and the first circuit component is electrically connected to the camera component. 
     In some embodiments, the camera device further includes an elastic connecting piece disposed on the first frame and electrically connecting to the driving component. 
     In some embodiments, the camera device further includes a base and a cover. The base and the cover cover the first frame and the second frame. The base and the cover respectively have protrusions. The first frame has guiding grooves, and the protrusions of the base and the cover are correspondingly disposed in the guiding grooves. 
     In some embodiments, the base further has a guiding wall, and the guiding walls cooperate with the driving component to limit the first frame to move. 
     In some embodiments, the camera device further includes a second circuit component. The second circuit component is fixedly disposed on the first frame and includes a second flexible circuit board surrounding the first frame and a second connector disposed at one end of the second flexible circuit board, and the second circuit component is electrically connected to the driving component.

The second upper frame and the second lower frame are paired in the third direction, and the second upper frame and the second lower frame together form the second arc surface. 
     The camera device of the present disclosure may be roughly divided into the first frame located on the outside, the second frame located in the inside, and the camera component located on the second frame. Furthermore, by disposing the contact surfaces between the first frame and the second frame as arc surfaces corresponding to each other, the second frame located inside the first frame and the camera component therein may rotate like a sphere. That is, when the second frame rotates with the first direction, the second direction, and/or the third direction as the axis, the first arc surface and the second arc surface are moving relative to each other. Therefore, the rotation of the second frame relative to the first frame may be guided to stabilize the rotation trajectory of the second frame. In this case, the interference between the various components may be reduced by the spherical structure, therefore the compensation angle may be greatly improved. In addition, the second frame and the camera component may also be driven by the driving component to roll with the direction parallel to the optical axis as the axis. That is, the present disclosure realizes a camera device with a large compensation angle and five-axis compensation. Furthermore, the first frame and the second frame may make the second frame relatively the first frame has the rotation degrees of freedom of the first direction, the second direction, and the third direction at the same time by the first arc surface and second arc surface. Wherein the first arc surface and second arc surface spherically match each other. Due to no need for disposing the rotation structure and rotation shaft corresponding to each axis, the overall complexity and cost are reduced.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be described clearly and completely in conjunction with specific embodiments and the figures of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of this disclosure. 
     The following description is of the best-contemplated mode of carrying out the present disclosure. This description is made for the purpose of illustrating the general principles of the present disclosure and should not be taken in a limiting sense. The scope of the present disclosure is best determined by reference to the appended claims. 
       FIG.  1    to  FIG.  3    respectively are a schematic diagram, an exploded view, and another exploded view of the camera device according to the first embodiment of the present application, and  FIG.  4    is a schematic diagram of the first frame body, the second frame body, and the camera component according to the first embodiment of the present application. As shown in the figures, the camera device  1   a  includes a first frame  10   a , a second frame  11   a , a camera component  12 , and a driving component DC, wherein the driving component DC may include a first driving component  13  and a second driving component  14  (as shown in  FIG.  4   ). The first frame  10   a  includes a first arc surface  100 , and the first arc surface  100  is on an inner surface of the first frame  10   a  and recesses inward to form a circular arc shape. The second frame  11   a  is movably disposed in the first frame  10   a  and includes a second arc surface  110 . The second arc surface  110  is on the outer surface of the second frame  11   a  and protrudes outward to form a circular arc shape. The first arc surfaces  100  of the first frame  10   a  cooperates with the second arc surface  110  of the second frame  11   a . More specifically, the circular arc shape of the first arc surface  100  and the circular arc shape of the second arc surface  110  are concentric circles. The camera component  12  is fixedly disposed in the second frame  11   a . With the structure mentioned above, the second frame  11   a  and the camera component  12  therein may rotate like a ball in the first frame  10   a  (as shown in  FIG.  4    ), therefore the compensation angle is greatly increased. 
     As shown in  FIG.  4   , the driving component DC (for example, the first driving component  13  and the second driving component  14 ) is configured to drive the second frame  11   a  to rotate with a first direction d1, a second direction d2, and a third direction d3 as axes. The first direction d1, the second direction d2, and the third direction d3 are orthogonal to each other, and the third direction d3 is parallel to an optical axis d of the camera component  12 . The first arc surface  100  and the second arc surface  110  are configured to move relative to each other when the second frame  11   a  rotates with the first direction d1, the second direction d2, and/or the third direction d3 as the axis. In some embodiments, the rotation with the first direction d1 as the axis may be represented to “pitch”, the rotation with the second direction d2 as the axis may be represented to “yaw”, and the rotation with the third direction d3 as the axis may be represented to “roll”. That is, not only a large compensation angle may be achieved, but also five-axis compensation may be achieved by combining the first driving component  13  and the second driving component  14  with the spherical structure mentioned above. It should be noted that the compensation angle range of the present disclosure may be within ±3 degrees, which is significantly better than ±1.5 degrees of the existing device. 
     The various elements mentioned above will be further explained hereinafter, and different implementation aspects will be provided for reference in order to make the technology of the present disclosure clearer and easier to understand. 
       FIG.  5    and  FIG.  6    respectively are a schematic diagram of the first frame and a schematic diagram of the second frame of the first embodiment of the present disclosure. As shown in the figures, in some embodiments, the first driving component  13  includes a first magnet  130 , a first coil  131 , a second magnet  132 , and a second coil  133 . The first magnet  130  is disposed on the second frame  11   a . The first coil  131  is disposed on the first frame  10   a  and corresponds to the first magnet  130 , and the first magnet  130  is configured to interact with the first magnet  130  to drive the second frame  11   a  to rotate with the first direction d1 as the axis. More specifically, the first coil  131  may be a copper wire, an aluminum wire, an alloy wire, or a wire with good electrical conductivity, which may generate a magnetic field when energized. On the other hand, the first magnet  130  is a permanent magnet having an inherent magnetic field. As a result, the first coil  131  and the first magnet  130  attract or repel to each other when the magnetic field generated by the electrification of the first coil  131  generates electromagnetic interaction with the inherent magnetic field of the first magnet  130 . The second frame  11   a  may be driven to move relative to the first frame  10   a  through the interaction between the first coil  131  and the first magnet  130 . The first coil  131  and the first magnet  130  are arranged along the second direction d2 to drive one side of the second frame  11   a  close to the first coil  131  to rise/decline and to relatively drive the other side of the second frame  11   a  to decline/rise. From another perspective, the decline/rise process of the side of the second frame  11   a  close to the first coil  131  is the process of rotating the second frame  11   a  with the first direction d1 as the axis. From another perspective, the decline/rise process of the side of the second frame  11   a  close to the first coil  131  is the process of rotating the second frame  11   a  with the first direction d1 as the axis. 
     The second magnet  132  is disposed on the second frame  11   a . The second coil  133  is disposed on the first frame  10   a  and corresponds to the second magnet  132 , and the second coil  133  is configured to interact with the second magnet  132  to drive the second frame  11   a  to rotate with the second direction d2 as the axis. The motion principle of the second coil  133  and the second magnet  132  is similar to that of the first coil  131  and the first magnet  130 , therefore the description thereof is omitted. Wherein, the second coil  133  and the second magnet  132  are arranged along the first direction d1 to drive one side of the second frame  11   a  close to the second coil  133  to rise/decline, and relatively drive the other side of the second frame  11   a  to decline/rise. From another perspective, the rise/decline process of the side of the second frame  11   a  close to the second coil  133  is the process of rotating the second frame  11   a  with the second direction d2 as the axis. 
     In some embodiments, the second driving component  14  includes a third magnet  140 , a third coil  141 , a fourth magnet  142 , and a fourth coil  143 . The third magnet  140  is disposed on the second frame  11   a . The third coil  141  is disposed on the first frame  10   a  and corresponds to the third magnet  140 , and the third coil  141  is configured to interact with the third magnet  140  to drive the second frame  11   a  to positively rotate with the third direction d3 as the axis. The fourth magnet  142  is disposed on the second frame  11   a . The fourth coil  143  is disposed on the first frame  10   a  and corresponds to the fourth magnet  142 , and the fourth coil  143  is configured to interact with the fourth magnet  142  to drive the second frame  11   a  to oppositely rotate with the third direction d3 as the axis. The motion principles of the third coil  141 , the third magnet  140 , the fourth coil  143 , and the fourth magnet  142  are similar to those of the first coil  131  and the first magnet  130 , and the description thereof is omitted. The third coil  141  and the third magnet  140  are arranged along the first direction d1, and the fourth coil  143  and the fourth magnet  142  are arranged along the second direction d2, thereby driving the second frame  11   a  to clockwise or counterclockwise rotate with the third direction d3 as the axis(or with the optical axis d of the camera component  12  as the axis). 
     In some embodiments, the camera device  1   a  further includes a plurality of positioning iron-pieces  15 . The plurality of positioning iron-pieces  15  respectively are disposed in the first coil  131 , the second coil  133 , the third coil  141 , and the fourth coil  143 . Wherein, the inherent magnetic fields of the first magnet  130 , the second magnet  132 , the third magnet  140 , and/or the fourth magnet  142  attract the plurality of positioning iron-pieces  15 . When the camera device  1   a  is not powered, the first driving component  13  and the second driving component  14  do not operate. As the result, the first magnet  130 , the second magnet  132 , the third magnet  140 , and/or the fourth magnet  142  are close to the plurality of positioning iron-pieces  15  without interference from the magnetic field of the coil, so that the camera component  12  maintains a neutral position. 
     As shown in  FIG.  2    and  FIG.  3   , in some embodiments, the camera device  1   a  further includes a first circuit component  16  used to connect an external electronic device and the camera component  12 . Therefore, focusing of the camera component  12  may be controlled by the signal and the power supply of the external electronic device through the first circuit component  16 . More specifically, the first circuit component  16  is movably disposed on the first frame  10   a  and includes a first flexible circuit board  160  surrounding the first frame  10   a  and a first connector  161  disposed at one end of the first flexible circuit board  160 . By disposing the first circuit component  16  with a three-dimensional structure (that is, the first circuit component  16  may be in contact with the first frame  10   a  to a certain extent but does not move with the first frame  10   a ), the interference between the first circuit component  16  and other components may be effectively reduced. As shown in  FIGS.  2 - 4    and  FIG.  11   , the first flexible circuit board  160  surrounds the first frame  10   a  on a reference plane parallel to the first direction d1 and the second direction d2, and the first flexible circuit board  160  surrounds the optical axis d of the camera component  12 . As shown in  FIG.  2   , in some embodiments, the first flexible circuit board  160  further comprises a horizontal section  162  parallel to the first direction d1 and the second direction d2 and a surrounding section  163  parallel to the third direction d3. The first connector  161  is on the horizontal section  162 , and the surrounding section  163  extends from the horizontal section  162  and surrounds the first frame  10   a . In some embodiments, the horizontal section  162  comprises an annular connecting part  1621 , and the annular connecting part  1621  has a hollow portion  1622  for receiving optical component. The surrounding section  163  has two ends respectively connected to two sides of the annular connecting part  1621  opposite to each other. 
     As shown in  FIG.  3   , in some embodiments, the camera device  1   a  further includes an elastic connecting piece  17 . The elastic connecting piece  17  is disposed on the first frame  10   a  and is electrically connected to the first driving component  13  and the second driving component  14  of the driving component DC. More specifically, the elastic connecting piece  17  is used to connect the external electronic device with the first driving component  13  and the second driving component  14  of the driving component DC. The current direction of each coil (ie, the first coil  131 , the second coil  133 , the third coil  141 , and the fourth coil  143 ) may be controlled by the signal and power supply of the external electronic device through the elastic connecting piece  17 , therefore the compensation effect in three directions is achieved. 
     As shown in  FIG.  2   ,  FIG.  5   ,  FIG.  7   , and  FIG.  8   , wherein  FIG.  7    and  FIG.  8    respectively are a schematic diagram and another schematic diagram of the base and the cover according to the first embodiment of the present disclosure. More specifically,  FIG.  7    and  FIG.  8    respectively are a perspective view of the base and the cover and a perspective view after being turned over. As shown in the figures, in some embodiments, the camera device  1   a  further includes a base  180  and a cover  181 , and the base  180  and the cover  181  cover the first frame  10   a  and the second frame  11   a . The base  180  and the cover  181  respectively have protrusions  182  (as shown in  FIG.  8    and  FIG.  9   ), the upper and lower surfaces of the first frame  10   a  respectively have guiding grooves  101  (as shown in  FIG.  5   ). The protrusions  182  of the base  180  and the cover  181  are correspondingly disposed in the guiding grooves  101 . The compensation angle may be effectively increased by providing the protrusions  182  and the guiding grooves  101  since the elastic connecting piece  17  mentioned above may hinder the rotation of the second frame  11   a  with the third direction d3 as the axis. It should be noted that, in the present embodiment, the base  180  and the cover  181  respectively have three protrusions  182 , and the upper and lower surfaces of the first frame  10   a  respectively have three guiding grooves  101 . However, the present disclosure is not limited thereto. In other embodiments, the number of the protrusions  182  may be one, two, four, five, or more than five, and the number of the guiding grooves  101  may be disposed according to the number of the protrusions  18 . 
     In some embodiments, the base  180  also has guiding walls  183  that cooperate with driving component DC (eg, first driving component  13  and second driving component  14 ) to limit the activity of first frame  10   a . In the present disclosure, the number of guiding walls  183  corresponds to the number of coils in the first driving component  13  and the second driving component  14 . That is, the number of the guiding walls  183  is four, and the four guiding walls  183  are respectively disposed to correspond the first coil  131  to the fourth coil  143 . 
     In some embodiments, the camera component  12  includes a closed-circuit motor, a camera lens, and a circuit board (not shown). The closed-circuit motor and the circuit board connect to the external electronic device through the first circuit component  16  to adjust the focus of the camera lens. For example, the closed-circuit motor may be actuated by the interaction between the coil and the magnet, or the focus of the camera lens may be controlled by a method well known by a person having ordinary skills in the art. The description of the method is omitted. 
       FIG.  9    is an exploded view of the first frame and the second frame according to the first embodiment of the present disclosure. As shown in the figure, in some embodiments, the first frame  10   a  further includes a first upper frame  102   a  and a first lower frame  103   a . The first upper frame  102   a  and the first lower frame  103   a  are paired in third direction d3, and the first upper frame  102   a  and the first lower frame  103   a  together form the first arc surface  100 . The second frame  11   a  further includes a second upper frame  111   a  and a second lower frame  112   a . The second upper frame  111   a  and the second lower frame  112   a  are paired in the third direction d3, and the second upper frame  111   a  and the second lower frame  112   a  together form the second arc surface  110 . It should be noted that the combination mentioned above is only an example, and the first frame  10   a  and the second frame  11   a  may also be integrally formed. Alternatively, the first frame  10   a  and the second frame  11   a  may also be assembled by more components, which may be adjusted according to the requirements of the manufacturing process. 
     As shown in  FIG.  2    and  FIG.  3   , in some embodiments, the camera device  1   a  further includes a case  19 . The case  19  is disposed on the first frame  10   a , and the case  19  has a camera opening  190 . The camera lens of the camera component  12  is exposed from the camera opening  190 . The case  19  is used to protect the components inside from external dust and moisture, thereby effectively extending the life of the product. It should be noted that the shape of the case  19  is not limited to the shape shown in  FIG.  2    and  FIG.  3   . For example, the case  19  may also be snapped onto other electronic products. That is, the camera device  1   a  of the present disclosure may be linked with other electronic products. In some embodiments, the first frame  10   a  is an annular frame penetrated along the optical axis d of the camera component  12 . The second frame  11   a  is an annular frame penetrated along the optical axis d of the camera component. In some embodiments, the camera opening  190 , the first frame  10   a , the second frame  11   a , and the hollow portion  1622  of the annular connecting part  1621  are aligned with one another along the optical axis d. Light is able to enter optical component in or below the hollow portion  1622  along the optical axis d. Based on a compact and efficient configuration, the camera device  1   a  has a lesser thickness along the optical axis d. 
       FIG.  10    to  FIG.  12    respectively are a schematic diagram, an exploded view, another exploded view of the camera device according to the second embodiment of the present application, and  FIG.  13    is a schematic diagram of the first frame body, the second frame body, and the camera component according to the second embodiment of the present application. More specifically, the camera device  1   b  includes a first frame  10   b , a second frame  11   b , a camera component  12 , and a driving component DC (eg, a first driving component  13  and a second driving component  14 ). The first frame  10   b  includes a first arc surface  100 , and the first arc surface  100  is at the inner surface of the first frame  10   b  and recesses inward to form a circular arc shape. The second frame  11   b  is movably disposed in the first frame  10   b  and includes a second arc surface  110 . The second arc surface  110  is on the outer surface of the second frame  11   b  and protrudes outward to form a circular arc shape. The second arc surface  110  of the second frame  11   b  and the first arc surface  100  of the first frame  10   b  cooperate with each other. The driving component DC is configured to drive the second frame  11   b  to rotate with the first direction d1, the second direction d2, and the third direction d3 as axes. The first direction d1, the second direction d2, and the third direction d3 are orthogonal to each other, and the third direction d3 is parallel to an optical axis d of the camera component  12 . Wherein, when the second frame  11   b  rotates with the first direction d1, the second direction d2, and/or the third direction d3 as the axis, the first arc surface  100  and the second arc surface  110  are configured to move relative to each other. Based on the features mentioned above, the operation principle of the present embodiment is the same as that of the first embodiment. Therefore, the elements with similar or identical functions and their descriptions may be referred to hereinbefore, and the detailed descriptions thereof are omitted. 
       FIG.  14    is a schematic diagram of the first frame according to the second embodiment of the present disclosure. As shown in the figure, the first frame  10   b  of the present embodiment is different from the first frame  10   a  of the first embodiment. Furthermore, the first frame  10   b  of the present embodiment is redesigned based on the base  180 , the cover  181 , and the first frame  10   a  in the first embodiment. The interference between components may be more effectively reduced by combining the first frame  10   a  with the base  180  and the cover  181  (ie, the first frame  10   b ). More specifically, the camera device  1   b  of the present embodiment does not include the elastic connecting piece  17 , but uses a second circuit component  20  to replace the function of the elastic connecting piece  17  (explained hereinafter). As a result, the second frame  11   b  and the camera component  12  therein may have full degrees of freedom without the elastic connecting piece  17 . Therefore, the providing of the guiding grooves  101  on the first frame  10   b  to assist the second frame  11   b  to rotate with the third direction d3 as the axis is unnecessary. 
     As shown in  FIG.  11    and  FIG.  12   , in the present embodiment, the camera device  1   b  further includes a second circuit component  20 . The second circuit component  20  is fixedly disposed on the first frame  10   b  and includes a second flexible circuit board  200  surrounding the first frame  10   b  and a second connector  201  disposed at one end of the second flexible circuit board  200 . The second circuit component  20  is electrically connected to the first driving component  13  and the second driving component  14  of the driving component DC. As shown in  FIG.  4   ,  FIG.  11    and  FIG.  12   , the second flexible circuit board  200  surrounds the first frame  10   b  on a reference plane parallel to the first direction d1 and the second direction d2, and the second flexible circuit board  200  surrounds the optical axis d of the camera component  12 . In some embodiments, the second flexible circuit board  200  further comprises a horizontal section  202  parallel to the first direction d1 and the second direction d2 and a surrounding section  202  parallel to the third direction d3. The second connector  201  is on the horizontal section  202 , and the surrounding section  203  extends from the horizontal section  202  and surrounds the first frame  10   b . The surrounding section  203  comprises a first connecting part  2031  and a second connecting part  2032 . The first connecting part  2031  and the second connecting part  2032  are spaced from each other. The first connecting part  2031  is connected to the first driving component  13  of the driving component DC, and the second connecting part  2032  is connected to the second driving component  14  of the driving component DC. The length of the second connecting part  2032  along the third direction d3 is greater than the length of the first connecting part  2031  along the third direction d3. 
       FIG.  15    is an exploded view of the first frame and the second frame according the second embodiment of the present disclosure. As shown in the figure, in some embodiments, the first frame  10   b  also includes a first upper frame  102   b  and a first lower frame  103   b . The first upper frame  102   b  and first lower frame  103   b  are paired in third direction d3, and the first upper frame  102   b  and the first lower frame  103   b  together form the first arc surface  100 . The second frame  11   b  further includes a second upper frame  111   b  and a second lower frame  112   b . The second upper frame  111   b  and the second lower frame  112   b  are paired in the third direction d3, and the second upper frame  111   b  and the second lower frame  112   b  together form the second arc surface  110 . It should be noted that the combination mentioned above is only an example, and the first frame  10   b  and the second frame  11   b  may also be integrally formed. Alternatively, the first frame  10   b  and the second frame  11   b  may also be assembled by more components, which may be adjusted according to the requirements of the manufacturing process. 
     In summary, the camera device of the present disclosure may be roughly divided into the first frame located on the outside, the second frame located in the inside, and the camera component located on the second frame. Furthermore, by disposing the contact surfaces between the first frame and the second frame as arc surfaces corresponding to each other, the second frame located inside the first frame and the camera component therein may rotate like a sphere. That is, when the second frame rotates with the first direction, the second direction, and/or the third direction as the axis, the first arc surface and the second arc surface are moving relative to each other. Therefore, the rotation of the second frame relative to the first frame may be guided to stabilize the rotation trajectory of the second frame. In this case, the interference between the various components may be reduced by the spherical structure, therefore the compensation angle may be greatly improved. In addition, the second frame and the camera component may also be driven by the driving component to roll with the direction parallel to the optical axis as the axis. That is, the present disclosure realizes a camera device with a large compensation angle and five-axis compensation. Furthermore, the first frame and the second frame may make the second frame relatively the first frame has the rotation degrees of freedom of the first direction, the second direction, and the third direction at the same time by the first arc surface and second arc surface. Wherein the first arc surface and second arc surface spherically match each other. Due to no need for disposing the rotation structure and rotation shaft corresponding to each axis, the overall complexity and cost are reduced.
