Description

Periscopic camera module, multi-camera module and camera module driving method

Technical Field

The application relates to the field of camera modules, and more particularly to a periscopic camera module, a multi-camera module and a driving method of the camera module.

Background

With the popularization of mobile electronic devices (especially smart phones), the importance of camera modules applied to mobile electronic devices for helping users to obtain images (such as videos or images) is becoming more and more prominent.

In recent years, terminal electronic devices capable of simultaneously performing close-range shooting and long-range shooting are becoming more popular in the market, and demands for long-range shooting are becoming more and more intense. However, the camera module configuration required for long-range shooting is contradictory to the trend of miniaturization and thinning of terminal equipment: in order to realize long-range shooting, the camera module needs to have a larger focal length, and in the design of the traditional upright module, the overall size (especially the height) of the camera module is increased, which inevitably affects the application of the camera module on the terminal equipment.

Therefore, a scheme of turning the optical path is proposed in the market to realize long-range shooting, namely, a periscopic camera module. Compared with the conventional vertical camera module, the periscopic camera module has a special optical system, allows the camera module to have a larger focal length through bending of the optical path, and has a height dimension close to that of the vertical camera module, so that the assembly requirement of the terminal equipment can be met.

Although the existing periscopic camera module realizes the capability of long-range shooting to a certain extent, the existing periscopic camera module still cannot well meet the market requirements. Compared with the conventional upright camera module, the periscopic camera module has more complex design of an optical system and structural design, and meets the requirements of configuring optical anti-shake and automatic focusing functions, and the development of the periscopic camera module is limited by the factors.

Detailed Description

Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.

Schematic camera module

Fig. 1 illustrates a perspective view of an optical system of a periscopic camera module according to an embodiment of the present application, the periscopic camera module has a specific optical system design scheme, so that the periscopic camera module constructed around the optical system has a more compact structure in structure. In addition, the optical design scheme of the periscopic camera module is suitable for adjusting the optical performance of the periscopic camera module, and particularly, in the embodiment of the application, the periscopic camera module adopts a specific driving mode to perform optical adjustment, so that the periscopic camera module has relatively high optical adjustment efficiency.

As shown in fig. 1, the optical system of the periscopic imaging module 80 according to the present embodiment sequentially includes, along the photosensitive path thereof: the light-sensitive lens comprises a first light-turning element 21, a lens group 10, a light-turning component 20 and a photosensitive chip 30, wherein the first light-turning element 21 is used for receiving and turning a light beam from a shot object to form a first light beam; the lens group 10 corresponds to the first light turning element 21, and is used for receiving the first light beam to form a second light beam; the light-turning component 20 corresponds to the lens group 10, and is used for folding the second light beam so as to allow the periscopic module to have a relatively larger effective focal length; the photosensitive chip 30 corresponds to the light folding assembly and is used for receiving the imaging light beam from the light turning assembly 20. In particular, in the embodiment of the present application, the light turning component 20 can reflect the second light beam from the lens group 10 at least twice, that is, the light turning component 20 has at least two light turning surfaces. In particular, in the embodiment of the present application, the light turning assembly 20 includes at least two light turning elements for reflecting the second light beam from the lens group 10 multiple times to perform optical path folding, thereby facilitating the structural design of the periscopic camera module 80.

As shown in fig. 1, the light turning component 20 includes a second light turning element 22 and a third light turning element 23, wherein the second light turning element 22 corresponds to the lens group 10 and is configured to turn the second light beam to form a third light beam; the third light turning element 23 corresponds to the second light turning element 22 and is configured to turn the third light beam to form a fourth light beam. In the embodiment of the present application, the photosensitive chip 30 corresponds to the third light turning element 23, and is configured to receive the fourth light beam for imaging.

More specifically, in the embodiment of the present application, the first light turning element 21 is disposed at the light inlet of the periscopic camera module 80, and the external light beam propagates to the first light turning element 21 through the light inlet of the periscopic camera module 80 and is reflected by the first light turning element 21 to form a first light beam having a first optical axis, where the first optical axis of the first light beam is substantially perpendicular to the optical axis of the external light beam, that is, the first light turning element 21 turns the external light beam substantially at 90 °. In the embodiment of the present application, the first light turning element 21 has a first light turning surface 210, and the first light turning surface 210 forms an angle of substantially 45 ° with an axis of the external light beam, wherein the external light beam turns at the first light turning surface 210 to form the second light beam.

The lens assembly 10 corresponds to the first light turning element 21, and more specifically, the lens assembly 10 is disposed behind the first light turning element 21 along the first optical axis direction, wherein the central axis of the lens assembly 10 is flush with the first optical axis. Accordingly, the first light beam passes through the lens group 10 to form a second light beam having a second optical axis, which is coaxial with the first optical axis.

The second light turning element 22 corresponds to the lens group 10, and more specifically, the second light turning element 22 is disposed at one side of the lens group 10 along the second optical axis direction for turning the second light beam to form a third light beam, wherein the optical axis of the third light beam is substantially perpendicular to a plane set by the first optical axis (or the second optical axis) and the optical axis of the external light beam. In the embodiment of the present application, the second light turning element 22 has a second light turning surface 220, the second light turning surface 220 and the second optical axis form an included angle of substantially 45 °, wherein the second light beam is turned at the second light turning surface 220 to form the third light beam.

The third light turning element 23 corresponds to the second light turning element 22, and more specifically, the third light turning element 23 is disposed at one side of the second light turning element 22 along the direction of the third optical axis for turning the third light beam to form a fourth light beam, wherein the fourth optical axis of the fourth optical path is substantially perpendicular to the third optical axis. In the embodiment of the present application, the third light turning element 23 has a third light turning surface 230, the third light turning surface 230 forms an included angle of substantially 45 ° with the third optical axis, wherein the third light beam is turned at the third light turning surface to form the fourth light beam.

Correspondingly, in the embodiment of the present application, the photosensitive path of the periscopic camera module 80 is: firstly, external light beams enter the periscopic camera module 80 through a light inlet of the module; then, the external light beam is 90 ° bent at the first light turning element 21 to form a first light beam; then, the first light beam passes through the lens assembly 10 to form a second light beam; then, the second light beam is turned again by 90 ° at the second light turning element 22 to form a third light beam; then, the third light beam is turned by 90 ° again at the third light turning element 23 to form a fourth light beam; finally, the fourth light beam is received by the photosensitive chip 30 to perform an imaging reaction.

Through the above optical system design, the beam path from the lens group 10 to the photosensitive chip 30 is folded, so that the periscopic camera module 80 can have a larger back focal length in a limited space, that is, the periscopic camera module 80 can have a larger effective focal length. In particular, in the embodiment of the present application, the Effective Focal Length (EFL) of the periscopic camera module 80 according to the embodiment of the present application may be greater than 15mm, and may even be greater than 20mm, for example, 15mm, 20mm, 25mm, 30mm, 35mm, and the like; the angle of view FOV can be less than 25 degrees, even less than or equal to 20 degrees

It should be understood that when the periscopic camera module 80 has a relatively large effective focal length, if the optical system of the periscopic camera module 80 is not specially configured, the periscopic camera module 80 may have a long back focal length and total optical length, which may result in an excessively long overall length of the periscopic camera module 80 and an excessively large aspect ratio of the periscopic camera module 80. Accordingly, in the embodiment of the present application, the first light turning element 21 turns the longitudinal external light beam into the transverse first light beam to reduce the height dimension of the periscopic camera module 80, and particularly, in the embodiment of the present application, the dimension of the periscopic camera module 80 in the height direction thereof may reach less than or equal to 8mm, or even less than or equal to 7 mm. The light turning assembly 20 folds the light beam from the lens group 10, so as to effectively shorten the total length of the periscopic camera module 80. It should be noted that, in the embodiment of the present application, the first light turning element 21, the second light turning element 22 and the third light turning element 23 have a special layout, such that the third optical path is perpendicular to the plane defined by the first and second optical paths, in this way, the periscopic camera module 80 has a relatively more compact structure, and, in particular, as shown in figures 2 and 3, in the embodiment of the present application, the size of the periscopic camera module 80 in the length direction thereof may be less than or equal to 35mm, and, the ratio of the dimension in the longitudinal direction thereof to the dimension in the width direction thereof may be closer to 1, that is, the aspect ratio is closer to 1, where the longitudinal direction of the periscopic imaging module 80 is the direction along the X axis as shown in the figure, the width direction is along the Y-axis, and the height direction is along the Z-axis as shown. More specifically, in the embodiment of the present application, the ratio between the size of the periscopic camera module 80 in the length direction and the size thereof in the width direction may be less than or equal to 2, further, may be less than or equal to 1.5, and even may be less than or equal to 1.3.

In a specific application example of the present application, when the periscopic camera module 80 is installed in a terminal device (e.g., a smartphone), since the length-width ratio of the periscopic camera module is closer to 1, that is, the periscopic camera module 80 is closer to a square in shape, the arrangement of internal components of the terminal device such as the smartphone is more regular and compact. Moreover, when the periscopic camera module 80 is configured on the upper half of a terminal device such as a smart phone, the size of the periscopic camera module 80 in the length direction thereof is reduced, so that the terminal device such as a smart phone can accommodate more components in the width direction, the upper half structure thereof can be more compact, and the terminal device such as a smart phone can leave more space for placing more bulky electronic components such as a battery.

In the embodiment of the present application, the first light-turning element 21, and the second light-turning element 22 and the third light-turning element 23 in the light-turning assembly 20 can be implemented as any optical element having a reflection function, including but not limited to: turning prisms, plane mirrors, optical waveguides, gratings, etc.

Preferably, in the embodiment of the present application, the lens group 10 includes at least three optical lenses, wherein, more preferably, the optical lens next to the first light turning element 21 is a glass lens, and the glass lens has a relatively very high refractive index, so that the periscopic camera module 80 has a higher incident light amount. The remaining optical lenses are not limited in the present application and may be made of glass lenses or other materials, such as plastic lenses, and preferably, the remaining optical lenses are plastic lenses in consideration of the cost, weight, assembly, and the like of the lens assembly 10. More preferably, in the embodiment of the present application, the lens group 10 includes at least one optical lens with positive power and one optical lens with negative power, so as to improve the imaging quality.

It should be noted that, in other examples of the embodiments of the present application, an anti-shake motor (not shown) may be configured for the lens assembly 10 to actuate the lens assembly 10 to achieve an optical anti-shake effect.

Further, in the embodiment of the present application, the second light turning element 22 and the third light turning element 23 cooperate with each other to fold the second light beam from the lens group 10. It should be noted that the light turning component 20 composed of the second light turning element 22 and the third turning element is disposed between the lens group 10 and the photosensitive chip 30, and therefore, an optical adjustment function can be realized by adjusting the position of the light turning component 20 relative to the photosensitive chip 30 and/or the lens group 10, and specifically, an autofocus and/or optical anti-shake can be realized by adjusting the relative positional relationship between the light turning component 20 relative to the photosensitive chip 30 and the lens group 10.

Specifically, in the embodiment of the present application, the periscopic camera module 80 further provides a driving component 40, and the driving component 40 is used for driving at least a portion of the light turning component 20 to perform optical adjustment. In the embodiment of the present application, the driving assembly 40 is configured to drive the second light turning element 22 and the third light turning element 23 to move along a specific direction for optical adjustment.

More specifically, in the embodiment of the present application, in one example, the driving component 40 configures driving elements, namely a first driving element 41 and a second driving element 42, for the second light turning element 22 and the third light turning element 23 respectively, wherein the first driving element 41 is used for actuating the second light turning element 22, and the second driving element 42 is used for actuating the third light turning element 23. Of course, in other examples of the present application, the driving assembly 40 may also drive the second light turning element 22 and the third light turning element 23 simultaneously to perform optical adjustment, for example, the second light turning element 22 and the third light turning element 23 are mounted on the same carrier, and then the carrier is driven by the driving assembly 40 to move the second light turning element 22 and the third light turning element 23 simultaneously, which is not limited by the present application.

Fig. 4 illustrates a driving control diagram of the periscopic camera module 80 according to the embodiment of the present application. As shown in fig. 4, the driving assembly 40 can be configured to drive the second turning element 22 and the third turning element 23 to move along the same direction of the third optical axis by the first driving element 41 and the second driving element 42, respectively, so as to perform optical anti-shake; alternatively, the driving assembly 40 can be configured to drive the second light turning element 22 and the third light turning element 23 to move along different directions of the third optical axis by the first driving element 41 and the second driving element 42, respectively, so as to perform auto-focusing.

Specifically, as shown in fig. 4, the driving assembly 40 can drive the light turning assembly 20 in 4 driving modes, wherein a driving mode a: the second light turning element 22 and the third light turning element 23 are driven to move along a first direction, wherein the first direction is a direction towards the second light turning element 22 along a third optical axis; driving method B: the second light turning element 22 and the third light turning element 23 are driven to move along a second direction, wherein the second direction is a direction towards the third light turning element 23 along a third optical axis. It should be understood that the combination of the driving method a and the driving method B can make the periscopic imaging module 80 have an optical anti-shake capability in the y-axis direction to compensate the shake of the imaging module in the y-axis direction. Driving method C: the second light turning element 22 is driven to move along the first direction, and the third light turning element 23 is driven to move along the second direction, so that the image distance (i.e. the distance from the lens group 10 to the photosensitive chip 30) can be increased, the object distance (i.e. the distance from the lens group 10 to the object to be photographed) can be reduced, and close-range shooting can be realized.
