Detailed Description
Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present application. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present application.
Various structural schematics according to embodiments of the present application are shown in the drawings. The figures are not drawn to scale, wherein certain details are exaggerated and possibly omitted for clarity of presentation. The shapes of various regions, layers, and relative sizes and positional relationships therebetween shown in the drawings are merely exemplary, and deviations may occur in practice due to manufacturing tolerances or technical limitations, and a person skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions, as actually required.
The periscopic camera module and the terminal device provided in the embodiments of the present application will be described in detail below. It should be understood that the specific features in the embodiments and examples of the present application are detailed description of the technical solutions in the embodiments of the present application, and are not limited to the technical solutions in the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
In a first aspect, an embodiment of the present application provides a periscopic camera module. As shown in fig. 1, the periscopic camera module includes: a first dimming component 110, a lens assembly 120, a zoom component, a second dimming component 130, and an image sensor 140.
The lens assembly 120 includes a solid optical lens group and a liquid lens 121 disposed in a matching manner. The optical axis of the liquid lens 121 coincides with the optical axis of the solid optical lens group. The solid optical lens group may include a plurality of optical lenses, for example, all of which may be plastic lenses. The liquid lens 121 may be of various types, and in particular, it may be an electro-wetting liquid lens, a mechanical-hydraulic liquid lens, a dielectric-driven liquid lens, or a liquid crystal lens, which is not limited in this embodiment.
The specific position of the liquid lens 121 in the lens assembly 120 depends on the specific optical path design, and may be, for example, on the light incident side, the light emergent side of the solid optical lens group, or between two adjacent lenses in the solid optical lens group. The liquid lens 121 has the advantages of fast response time, good imaging quality, light weight and small size, and can change the internal parameters of the lens through external control, thereby realizing continuous zooming. The liquid lens 121 is additionally arranged in the lens, so that the number of lenses is reduced, the zoom factor and the optical performance of the lens are improved, and the continuous zooming of the lens is realized.
The zoom component is used for adjusting the focal length of the lens assembly 120, and specifically includes a first zoom mechanism (not shown in the figure) and a second zoom mechanism 150. The first zoom mechanism is disposed in cooperation with the liquid lens 121 and configured to adjust a focal length of the liquid lens 121, and the second zoom mechanism 150 is disposed in cooperation with the entire lens assembly 120 and configured to drive the lens assembly 120 to move along the optical axis direction so as to adjust the focal length of the entire lens assembly 120. When zooming is needed, the whole lens assembly 120 can be driven to move to a specific position by the second zooming mechanism 150, and continuous zooming in a certain range is realized by adjusting the first zooming mechanism, which is beneficial to refining the focusing scale of the lens. The specific zoom range is designed according to the requirements of the practical application scene. For example, in one application scenario, a continuous zoom in the range of 2-10 times may be achieved.
Taking the liquid lens 121 for adjusting the focal length by controlling the curvature change as an example, the main-shooting function can be realized when the lens assembly 120 is in the state of being retracted to the original position. Further, the second zoom mechanism 150 drives the lens assembly 120 to move along the optical axis direction, so that the lens can extend to each specific position, and then the first zoom mechanism controls the curvature change of the liquid lens 121, and adjusts the EFL (Effective Focal Length) parameter to the theoretically designed range, so that the lens can realize the required continuous zoom magnification range. For example, in an application scenario, when the lens assembly extends to a certain specific position, under the control of the first zooming mechanism, 1-5 times of continuous zooming can be realized. That is to say, the camera module provided in this embodiment can integrate the functions of the current main camera lens and the telescopic lens, and implement continuous zooming.
To facilitate understanding of the operational state of the lens assembly 120, fig. 2-4 are schematic diagrams illustrating the lens assembly 120 in different operational states when the liquid lens 121 is located at different positions of the lens assembly 120. It should be noted that, in the schematic diagrams shown in fig. 2 to 4, the number of lenses included in the lens assembly 120 is only for illustration, and the specific number is designed according to actual needs, and in order to compare the distance between the lens retracted state and the extended state and the image sensor 140, the image sensor 140 is turned to the light-emitting side of the lens assembly 120 for illustration. In fig. 2 (a), the liquid lens is located on the light incident side of the solid optical lens group, and the entire lens assembly 120 is in a state of being retracted to the original position. In fig. 2 (b), the liquid lens is located on the light incident side of the solid optical lens group, and the entire lens assembly 120 is in an extended state. In fig. 3 (a), the liquid lens is located at an intermediate position of the solid optical lens group, and the entire lens assembly 120 is in a state of being retracted to the original position. In fig. 3 (b), the liquid lens is located at an intermediate position of the solid optical lens group, and the entire lens assembly 120 is in an extended state. In fig. 4 (a), the liquid lens is located on the light exit side of the solid optical lens group, and the entire lens assembly 120 is in a state of being retracted to the original position. In fig. 4 (b), the liquid lens is located on the light exit side of the solid optical lens group, and the entire lens assembly 120 is in an extended state.
In an alternative embodiment, the first zoom mechanism may change an internal parameter of the liquid lens 121, thereby adjusting the focal length of the liquid lens 121. For example, the liquid lens 121 is a liquid-filled lens, and the focal length can be adjusted by changing the curvature radius of the liquid lens 121. The liquid lens 121 has small driving power consumption, large zooming range and flexible aperture size, and the appearance is determined by the mechanical property of the film in the accommodating cavity and is irrelevant to the filling liquid. On this basis, the first zoom mechanism may employ a micro-motor driving structure for controlling the pressure applied to the liquid in the containing chamber of the liquid lens 121 according to the input voltage to adjust the radius of curvature of the liquid lens 121. Thus, by inputting different voltages to the micro-motor driving structure, the continuous change of the curvature radius of the liquid lens 121 can be controlled, thereby realizing the continuous zooming of the lens.
In an alternative embodiment, the second zoom mechanism 150 may employ an AF (Auto Focus) motor module, which can drive the lens assembly 120 to achieve a larger stroke position change, thereby achieving a larger zoom range. For example, the AF motor module may include a driving motor and a lens fixing structure for fixing the lens assembly 120. The driving motor is connected to the lens fixing structure for driving the lens fixing structure to move, so as to drive the whole lens assembly 120 to move.
The first dimming part 110 and the second dimming part 130 are each an optical part having an optical path turning function such as a reflecting prism or a reflecting mirror. In the embodiment of the present specification, by arranging the first and second dimming members 110 and 130 to turn the optical path, the image sensor 140 can be arranged parallel to the optical axis direction of the lens assembly 120, thereby reducing the thickness dimension of the camera module.
The second dimming member 130 is used to reflect the light emitted from the lens assembly 120 into the image sensor 140. In an alternative embodiment, in order to further reduce the thickness of the camera module, an infrared filter may be formed in the second light adjusting member 130, so that the light path turning function and the infrared light filtering function of the second light adjusting member 130 are integrated. At this time, the second dimming member 130 is used to filter infrared light from the light emitted from the lens assembly 120 and turn the light by 90 degrees, so that the light is incident to the photosensitive side of the image sensor 140 to be imaged. For example, an infrared filter may be formed on one or more surfaces of the reflective member by coating, so as to obtain the second dimming member 130.
Specifically, the second light adjusting member 130 may have various embodiments, and the embodiments of the present disclosure mainly illustrate the following three configurations, and in the specific implementation, other applicable configurations may be adopted, which is not limited herein. It should be noted that, in order to more clearly illustrate the optical path structure, fig. 5 to 7 below all show optical path diagrams of the periscopic imaging module provided in this embodiment.
First, as shown in fig. 5, the second dimming member 130 may include an infrared filter 132, a transparent substrate 131, and a reflective film 133, which are stacked. The transparent substrate 131 may be made of a substrate material with a high transmittance, such as glass, the infrared filter 132 may be formed on a first surface of the transparent substrate 131, and the reflective film 133 is formed on a second surface of the transparent substrate 131 opposite to the first surface. That is, the infrared filter film is coated on the first surface of the transparent substrate 131 by a coating method, and the reflective film is coated on the second surface. At this time, the light incident on the second light adjusting member 130 from the lens assembly 120 passes through the infrared filter 132, then passes through the transparent substrate 131, and is reflected by the reflective film 133 to the image sensor 140.
Second, the second dimming member 130 may include a substrate, a reflective film, and an infrared filter film, which are sequentially stacked. That is, the reflective film is first coated on the surface of the substrate, and then the infrared filter is formed on the surface of the reflective film. At this time, the light incident from the lens assembly 120 to the second light adjusting member 130 passes through the infrared filter, filters infrared light in the light, and is reflected to the image sensor 140 by the reflective film.
It can be understood that the light path turning can be sufficiently realized by the reflector formed by the substrate and the reflective film, and stray light brought to the camera module by insufficient light turning is avoided.
Third, as shown in fig. 6, the second dimming member 130 may include a reflection prism 134 and an infrared filter 135 formed on a target surface of the reflection prism 134. It can be understood that the reflection prism is a prism having a light turning function, and is generally a right-angle prism, and includes a first right-angle surface, a second right-angle surface and a reflection surface, and light incident from any one of the right-angle surfaces is totally reflected on the reflection surface to realize the turning of the light.
The target surface may include the first and/or second right angle faces of the reflective prism 134. For example, the first right-angle surface and the second right-angle surface of the reflection prism 134 may be formed with the infrared filter 135. At this time, light entering the reflection prism 134 from the lens assembly 120 enters the reflection surface after being filtered by the infrared light of the infrared filter 135 formed on the right-angle surface, is reflected by the reflection surface to the second right-angle surface, and exits to the photosensitive side of the image sensor 140 after being filtered by the infrared light of the infrared filter 135 formed on the second right-angle surface again. Thus, the infrared light in the light can be effectively filtered through the infrared light filtering treatment twice.
The first dimming member 110 is used to turn an externally incident light by 90 degrees so that the light is incident to the lens assembly 120. For example, the first dimming member 110 may employ a mirror or a reflective prism.
In an alternative embodiment, in order to further enhance the filtering effect on the infrared light and reduce the system stray light, as shown in fig. 7, the first light adjusting member 110 may include a reflective prism 111 and an infrared filter 112 formed on the target surface of the reflective prism 111, so that the first light adjusting member 110 also integrates the light path turning function and the infrared light filtering function. Thus, the infrared light in the light can be filtered more effectively through the dual infrared filtering function of the first dimming component 110 and the second dimming component 130. Wherein, the target surface of the reflection prism 111 may also include the first right-angle surface and/or the second right-angle surface of the reflection prism 111.
For example, the infrared filter 112 is formed on the first right-angle surface of the reflection prism 111 of the first light adjustment member 110. At this time, light incident on the reflection prism 111 from the outside is filtered by the infrared light of the infrared filter 112 formed on the first right-angle surface, enters the reflection surface, is reflected by the reflection surface, and then exits from the second right-angle surface to the lens assembly 120.
In specific implementation, the reflective prism 134 included in the second light adjusting unit 130 and the reflective prism 111 included in the first light adjusting unit 110 may be made of H-ZF3 (refractive index of 1.7173) optical glass material, or may be made of other high refractive index materials such as H-ZF4, H-ZF5, or H-ZF6 optical glass material. It can be understood that the higher the refractive index of the prism material, the smaller the size of the reflecting prism, but the higher the refractive index, the higher the material cost, and therefore, the material cost is determined according to the requirement of the light path design in the practical application scenario.
Therefore, light incident from the outside sequentially passes through the first dimming component 110, the lens assembly 120 and the second dimming component 130 to enter the photosensitive side of the image sensor 140 for imaging, and the image sensor 140 collects an image corresponding to the incident light, so that the image shooting function of the camera module is realized.
Further, in order to improve the imaging quality problem caused by the environmental shake factor, the periscopic camera module provided by the embodiment of the present specification further includes: an anti-shake fine adjustment mechanism 160. The anti-shake fine adjustment mechanism 160 is connected to the image sensor 140, and is configured to drive the image sensor 140 to move according to the shake signal, so as to compensate for an imaging offset caused by shake. For example, the anti-shake fine adjustment mechanism 160 may be a Shape Memory Alloy (SMA) actuator, a Spring (Spring) actuator, or a piezoelectric actuator. Assuming that the direction perpendicular to the photosensitive side of the image sensor 140 is the Z-axis direction, a rectangular coordinate system is established, and the image sensor 140 is driven to move, so that the anti-shake function in the X and Y directions is realized, and the purpose of clear imaging is achieved.
Compared with the anti-shake fine adjustment mechanism connected to the lens assembly 120, the anti-shake fine adjustment mechanism 160 connected to the image sensor 140 can prevent the anti-shake fine adjustment mechanism 160 from affecting the stability of the internal parameters of the liquid lens 121, such as the curvature radius, during the operation, so as to affect the stability of the focal length of the lens, which is beneficial to further improving the imaging quality.
The periscopic camera module that this application embodiment provided, through collocation liquid lens 121 in camera lens subassembly 120, combine first zoom mechanism and second zoom mechanism 150 to adjust the focus of camera lens subassembly 120 jointly, realized the continuous zoom of camera lens effectively to further refine the focusing scale of camera lens. Moreover, the zoom speed is high, and the achievable continuous zoom range is large.
In a second aspect, the embodiment of the present application further provides a terminal device, as shown in fig. 8, the terminal device 40 includes a display screen 200 and a periscopic camera module 100, and a photosensitive side of an image sensor 140 in the periscopic camera module 100 is disposed in parallel to the display screen 200. It is understood that the x-axis direction shown in fig. 8 is the thickness direction of the terminal apparatus 40, i.e., the height direction of the periscopic camera module 100 mounted in the terminal apparatus 40, and the y-axis direction is the length direction of the terminal apparatus 40. The detailed structure of the periscopic camera module 100 can refer to the description of the first aspect, and is not described herein again.
