[0102] The present disclosure provides a folding camera module having an incident optical axis and an exit optical axis, which includes a fixed carrier, a reflection element, a first lens group, a second lens group, and an electronic photosensitive element. The reflection element is used to fold an imaging light ray of the folding camera module from the incident optical axis to the exit optical axis, wherein the reflection element is fixed to the fixed carrier, and the reflection element includes an incident light surface and an exit light surface. The second lens group and the first lens group are jointly used to provide an optical refractive power of the folding camera module. The first lens group, the second lens group, and the incident light surface of the reflection element are arranged in sequence along the incident optical axis. The electronic photosensitive element is used to receive the imaging light ray of the folding camera module. The electronic photosensitive element and the exit light surface of the reflection element are arranged corresponding to each other along the exit optical axis. The second lens group is fixed to the fixed carrier so that there is no relative displacement between the second lens group and the reflection element. The folding camera module further includes a focusing driving device. The focusing driving device includes a fixed member, a movable member, and a sphere. The first lens group is arranged on the movable member. The sphere is arranged between the fixed member and the movable member, thereby providing a degree of freedom and a driving force for the first lens group to move along the direction parallel to the incident optical axis. The longest driving distance range of the first lens group by the focusing driving device is Dim, the height of the reflection element in a direction parallel to the incident optical axis is H, and the distance between the center of the image side surface of the second lens group and the center of the electronic photosensitive element along the direction parallel to the incident optical axis is Lf, which satisfies the following conditions: 0.8 mm < Dim < 3.9 mm; and 0 ≤ Lf < H. The present disclosure provides a miniaturized folding camera module. By configuring a mechanism that folds the overall optical path by more than 90 degrees, there is sufficient space for the grouped lens groups to perform internal focusing. By fixing the reflection element and a part of the lens groups and only driving another part of the lens groups for focusing, the weight-bearing burden of the focusing driving device can be reduced, a focusing driving device with lower power consumption and higher control accuracy can be provided, and the feasibility of long-distance driving of the internal focusing lens group can be provided. In addition, the foregoing conditional range can effectively reduce the physical back focal space of the folding camera module.

[0103] Specifically, the incident light surface and the emergent light surface of the reflecting element may be coplanar, but the present disclosure is not limited thereto. The longest driving distance range of the first lens group is the displacement amount from the position of the first lens group when the folding camera module is focused at infinity to the position of the first lens group when the folding camera module is focused at the minimum object distance. The minimum object distance of the folding camera module can have different object distance values according to the optical specification design values of different folding camera modules, and the present disclosure is not limited by the disclosed numerical values. In addition, the measurement of distance is a non-negative scalar, and the distance can be zero when the measurement positions are on the same reference position. Thereby, the overall height is reduced, providing a more sufficient feasible space for group focusing.

[0104] The longest driving distance range of the first lens group by the focusing driving device is Dim, which can satisfy the following conditions: 0.9 mm < Dim < 3.2 mm. Thereby, it is possible to have relatively high imaging quality both when shooting long-distance scenes and close-up scenes.

[0105] Furthermore, it can satisfy the following conditions: 1.0 mm < Dim < 2.6 mm. Thereby, the sensitivity of assembly tolerance is reduced, ensuring relatively high imaging quality during driving.

[0106] The perpendicular distance between the center of the electronic photosensitive element and the incident light axis is S, which can satisfy the following conditions: 4.5 mm < S < 20 mm. Thereby, under limited geometric space, an optical design scheme of a telephoto imaging system can be realized. Furthermore, it can satisfy the following conditions: 6.0 mm < S < 17 mm. Thereby, it is possible to prevent the electronic photosensitive element from colliding with the lens group and the focusing driving device during assembly, so as to improve the assembly efficiency.

[0107] The reflecting element is a plastic product and has at least one injection mark. Thereby, the manufacturing precision of the reflecting element is improved, and the mass production efficiency is increased.

[0108] The reflecting element includes at least two reflecting surfaces. Thereby, the reflecting element provides a larger turning angle.

[0109] The number of at least two reflecting surfaces is odd. Thereby, a miniaturized reflecting element is provided. Further, the reflecting surface of the reflecting element can be coplanar with the incident light surface, can be coplanar with the emergent light surface, or can be an independent surface, but the present disclosure is not limited thereto.

[0110] The first lens group includes at least one glass lens and at least one plastic lens. Thereby, the environmental tolerance is improved, providing the stability of optical quality.

[0111] The distance between the center of one object side of the second lens group and the center of the electronic photosensitive element along the direction parallel to the incident optical axis is Ls, and the distance between the center of the object side of the second lens group and the position where the outgoing optical axis passes through the outgoing surface of the reflecting element along the direction parallel to the incident optical axis is Le, and the following conditions can be satisfied: 0 ≤ Ls < Le. Thereby, the physical space of the long back-focus camera module can be effectively reduced, and a miniaturized optical system configuration can be provided.

[0112] The folding camera module may further include a two-dimensional image stabilization device. The two-dimensional image stabilization device is used to provide a driving force for the electronic photosensitive element to move on a plane perpendicular to the outgoing optical axis. Thereby, the effect of optical image stabilization of the folding camera module is provided.

[0113] The folding camera module may further include a three-dimensional image stabilization device. The three-dimensional image stabilization device is used to provide a driving force for the electronic photosensitive element to move in a three-dimensional space. Thereby, the effect of optical image stabilization of the folding camera module is provided. Specifically, the image stabilization device may use a sphere to provide the preloading force and degrees of freedom of the electronic photosensitive element, or may use an elastic element to provide the preloading force and degrees of freedom of the electronic photosensitive element, but the present disclosure is not limited thereto.

[0114] The present disclosure provides a folding camera module having an incident optical axis and an outgoing optical axis, which includes a fixed carrier, a reflecting element, a first lens group, a second lens group, and an electronic photosensitive element.

[0117] The number of at least two reflecting surfaces is odd. Thereby, a miniaturized reflecting element is provided.

Figure 1B Drawing according to Figure 1A Exploded view of the pivot camera module 100 according to the first embodiment; Figure 1C Drawing according to Figure 1B An exploded view of the three-dimensional image stabilization device 180 and the electronic photosensitive element 150 of the pivot camera module 100 according to the first embodiment. Figure 1D Drawing according to Figure 1A Another exploded view of the pivot camera module 100 of the first embodiment; Figure 1E Drawing according to Figure 1D An exploded view of the three-dimensional image stabilization device 180 and the electronic photosensitive element 150 of the deflection camera module 100 according to the first embodiment. The deflection camera module 100 has an entrance optical axis x and an exit optical axis y, and includes a fixed carrier 110, a reflective element 120, a first lens group 130, a second lens group 140, an electronic photosensitive element 150, a focusing drive device 160, an assembly fixture 170, and a three-dimensional image stabilization device 180. The reflective element 120 is used to deflect an imaging ray from the deflection camera module 100 from the entrance optical axis x to the exit optical axis y.

[0132] A reflective element 120 is fixed to a fixed carrier 110 and includes an incident light surface 121 and an exit light surface 122. A second lens group 140, together with the first lens group 130, provides optical refractive power to the tilting camera module 100. The incident light surfaces 121 of the first lens group 130, the second lens group 140, and the reflective element 120 are sequentially arranged along the incident optical axis x. An electronic photosensitive element 150 receives the imaging light from the tilting camera module 100. The electronic photosensitive element 150 and the exit light surface 122 of the reflective element 120 are correspondingly arranged along the exit optical axis y. The second lens group 140 is fixed to the fixed carrier 110 such that there is no relative displacement between the second lens group 140 and the reflective element 120. A focusing drive device 160 includes a fixed member 161, a sphere 162, and a movable member 163. The first lens group 130 is disposed on the movable member 163. The sphere 162 is disposed between the fixed member 161 and the movable member 163, thereby providing the first lens group 130 with a degree of freedom and a driving force to move along the direction parallel to the incident optical axis x.

[0133] Therefore, the first embodiment of the angled camera module 100, by configuring the overall optical path angled by more than 90 degrees, provides sufficient space for the clustered lens groups to perform internal focusing. By fixing the reflective element 120 and a portion of the lens group (i.e., the second lens group 140), and only driving the other portion of the lens group (i.e., the first lens group 130) for focusing, the load on the focusing drive device 160 can be reduced, providing a more energy-efficient focusing drive device 160 with higher control precision, and providing the feasibility of long-distance driving of the internal focusing lens group.

[0134] Depend on Figures 1B to 1E As can be seen, the three-dimensional image stabilization device 180 houses the electronic photosensitive element 150 and provides a driving force for the electronic photosensitive element 150 to move in a three-dimensional space. Specifically, the three-dimensional image stabilization device 180 includes a base 181, a first-direction driving member 182, a second-direction driving member 183, a third-direction driving member 184, and a plurality of spheres 185. The first-direction driving member 182, the second-direction driving member 183, and the third-direction driving member 184 are sequentially stacked in the base 181. The electronic photosensitive element 150 is connected to the third-direction driving member 184. The spheres 185 are respectively disposed on the base 181, the first-direction driving member 182, the second-direction driving member 183, and the third-direction driving member 184, enabling them to drive the electronic photosensitive element 150 to move relative to each other in a three-dimensional direction. However, the content disclosed herein is not limited to this. In other embodiments, an elastic element may be used instead of the sphere 185 to provide the preload and degrees of freedom of the electronic photosensitive element 150, but this disclosure is not limited thereto.

[0135] Please refer to Figure 1F and Figure 1G , Figure 1F Drawing according to Figure 1A A cross-sectional view of the pivot camera module 100 according to the first embodiment. Figure 1G Drawing according to Figure 1F A schematic diagram showing the first lens group 130 of the tilting camera module 100 moving along a direction parallel to the incident optical axis x in the first embodiment of the first implementation. Figure 1F It is understood that the first lens group 130 may include two lens elements 131 and 132, each comprising a glass lens and a plastic lens. This improves environmental tolerance and optical quality stability. Furthermore, the assembly fixture 170 positions the reflective element 120 within the fixed carrier 110 towards the fixed carrier 110, and the two sidewalls 171 of the assembly fixture 170 are located between the fixed carrier 110 and the reflective element 120, thereby improving assembly stability.

[0136] Figure 1GThe upper part illustrates the positional relationship between the first lens group 130 and the focusing drive device 160 when the tilting camera module 100 is focused at infinity. Figure 1G The lower half illustrates the positional relationship between the first lens group 130 and the focusing drive device 160 when the pivot camera module 100 is focused at the minimum object distance. The longest driving distance range of the first lens group 130 by the focusing drive device 160 is Dim, the height of the reflective element 120 along the direction parallel to the incident optical axis x is H, and the distance between the center of the image side of the second lens group 140 and the center of the electronic photosensitive element 150 along the direction parallel to the incident optical axis x is Lf.

[0137] The longest driving distance range Dim of the first lens group 130 is the displacement from the position of the first lens group 130 when the tilting camera module 100 is focused at infinity to the position of the first lens group 130 when the tilting camera module 100 is focused at the minimum object distance. The minimum object distance of the tilting camera module 100 can have different object distance values ​​depending on the optical specifications of different tilting camera modules 100. This disclosure is not limited to the disclosed values. In addition, the distance measurement is a non-negative quantifier, and the distance can be zero if the measurement positions are on the same reference position.

[0138] When the tilting camera module 100 is focused at infinity, the distance between the first lens group 130 and the second lens group 140 is less than the distance between the first lens group 130 and the second lens group 140 when the tilting camera module 100 is focused at the minimum object distance. This reduces the overall height and provides more feasible space for cluster focusing.

[0139] The center of the electronic photosensitive element 150 is perpendicularly distanced from the incident optical axis x by a distance S. This allows for the realization of an optical design scheme for a telephoto imaging system within a limited geometric space.

[0140] The distance between the center of the object side surface of the second lens group 140 and the center of the electronic photosensitive element 150 along the direction parallel to the incident optical axis x is Ls, and the distance between the center of the object side surface of the second lens group 140 and the position of the light-emitting surface 122 of the reflective element 120 along the direction parallel to the incident optical axis x is Le. In this way, the physical space of the long back focal length conversion camera module 100 can be effectively reduced, providing a miniaturized optical system configuration.

[0141] Depend on Figure 1GAs can be seen, in the first embodiment of the first implementation, the height H of the reflective element 120 along the direction parallel to the incident optical axis x, the longest driving distance range Dim of the first lens group 130 by the focusing drive device 160, the distance Lf between the center of the image side of the second lens group 140 and the center of the electronic photosensitive element 150 along the direction parallel to the incident optical axis x, the distance Le between the center of the object side of the second lens group 140 and the position of the light-emitting surface 122 of the reflective element 120 through the exit optical axis y along the direction parallel to the incident optical axis x, the distance Ls between the center of the object side of the second lens group 140 and the center of the electronic photosensitive element 150 along the direction parallel to the incident optical axis x, and the vertical distance S between the center of the electronic photosensitive element 150 and the incident optical axis x are the values ​​in Table 1 below.

Specifically, the light-incident surface 121 and the light-exiting surface 122 of the reflective element 120 may be coplanar, but this disclosure is not limited thereto. The reflective element 120 is a plastic product and has at least one injection mark 126. Further, the reflective element 120 includes reflective surfaces 123, 124, and 125, and the imaging light rays are deflected sequentially along the reflective surfaces 123, 125, and 124 to the electronic photosensitive element 150. The number of reflective surfaces 123, 124, and 125 is odd. In addition, the reflective surface 125 of the reflective element 120 may be coplanar with the light-incident surface 121, coplanar with the light-exiting surface 122, or a separate surface, but this disclosure is not limited thereto.

A second lens group 240, together with the first lens group 230, provides optical refractive power to the tilting camera module 200.

Figure 8A and Figure 8B As can be seen, the electronic device 10 is a smartphone, which includes multiple camera modules and a user interface 11. More specifically, the camera modules are an ultra-wide-angle camera module 12, telephoto camera modules 13 and 14, and a high-resolution camera module 15, and the user interface 11 is a touchscreen, but this is not a limitation. Specifically, the camera module can be any of the transitional camera modules described in the first to second embodiments, but this disclosure is not limited thereto.

[0166] The user enters the shooting mode through the user interface 11, which is used to display the screen and can be used to manually adjust the shooting angle to switch between different camera modules. At this time, the camera module gathers the imaging light onto an electronic photosensitive element (not shown) of the camera module and outputs electronic signals related to the image to the image signal processing element (ISP) 16.

[0167] Depend on Figure 8B As can be seen, depending on the camera specifications of the electronic device 10, the electronic device 10 may also include an optical image stabilization component (not shown in the figure).

This is beneficial to the autofocus function and optical image stabilization component configured in the camera module of the electronic device 10, so as to obtain good image quality and help the electronic device 10 according to the present disclosure to have multiple shooting modes, such as optimized Selfie, low light HDR (High Dynamic Range) imaging, and high resolution 4K video recording. In addition, users can directly view the camera's shooting screen through the user interface 11 and manually operate the framing range on the user interface 11 to achieve the WYSIWYG autofocus function.

Current electronic devices, such as smartphones, tend to be thinner and lighter. By mounting the camera module and related components on a flexible printed circuit board and then using a connector to integrate the circuitry onto the mainboard of the electronic device, the design and circuit layout requirements within the limited space of the electronic device can be met, providing greater flexibility. This also allows for more flexible control of the camera module's autofocus function through the electronic device's touchscreen. In the sixth embodiment, the electronic device 10 may include multiple sensing elements and multiple focus assist modules. The sensing elements and focus assist modules are mounted on a flexible printed circuit board and at least one other flexible printed circuit board (not shown), and electrically connected to the imaging signal processing element 16 and other related components via corresponding connectors to execute the shooting process. In other embodiments (not shown), the sensing element and auxiliary optical element may also be mounted on the motherboard of the electronic device or other types of carrier boards, depending on the mechanical design and circuit layout requirements.

[0169] Furthermore, the electronic device 10 may further include, but is not limited to, a display unit, a control unit, a storage unit, random access memory (RAM), read-only memory (ROM), or a combination thereof.

[0173] Depend on Figures 8C to 8E It is understood that by using camera modules with different focal lengths for framing and combining them with image processing technology, the electronic device 10 can achieve the function of zooming.
