The following describes a camera module 100 according to an embodiment of the present invention with reference to fig. 1 and 2.
The camera module 100 according to the embodiment of the present invention includes: a first lens assembly 10, a second lens assembly 20 and a drive assembly.
Specifically, the first lens assembly 10 includes a first lens 11, the second lens assembly 20 includes a second lens 21, the first lens 11 and the second lens 21 are movable between a first position and a second position, the driving assembly is connected to the first lens 11 to drive the first lens 11 to move, the first lens assembly 10 and the second lens assembly 20 respectively form images under the condition that the first lens 11 and the second lens 21 are located at the first position, and the first lens 11 is located on an imaging optical path of the second lens assembly 20 and cooperates with the first lens 11 to form images under the condition that the first lens 11 and the second lens 21 are located at the second position.
In other words, the camera module 100 according to the embodiment of the present invention mainly includes the first lens assembly 10 and the second lens assembly 20 capable of imaging respectively, and a driving assembly that drives the first lens assembly 10 and the second lens assembly 20 to move between different states. The first lens assembly 10 includes a first lens 11, and the first lens 11 is movable between a first position and a second position. As shown in fig. 2, when the first lens 11 is in the first position, the light may pass through the first lens 11 and realize imaging. The second lens assembly 20 includes a second lens 21, and the second lens 21 is also movable between a first position and a second position, and performs imaging when the second lens 21 is in the first position. That is, the first lens assembly 10 and the second lens assembly 20 may separately image, and the first lens 11 and the second lens 21 may be the same or different lenses, such as a telephoto lens, a wide-angle lens, and the like.
In addition, when the first lens 11 is driven to move by the driving component, as shown in fig. 1, the first lens 11 and the second lens 21 are in the second position, and the incident light sequentially passes through one of the first lens 11 and the second lens 21 and the other of the first lens 11 and the second lens 21, and is matched with the first lens 11 and the second lens 21 to realize imaging.
It should be noted that the driving assembly includes, but is not limited to, a motor, and may also be other driving structures capable of realizing the movement of parts or components such as the first lens 11, for example, a driving motor, a transmission mechanism including a driving motor and a driving motor cooperating with the driving motor, and the like.
Therefore, according to the camera module 100 of the embodiment of the invention, the driving component drives the first lens 11 and the second lens 21 to be movable between the first position and the second position, when the first lens 11 and the second lens 21 are in the first position, the first lens 11 and the second lens 21 can respectively realize imaging independently, and when the first lens 11 and the second lens 21 are in the second position, the first lens 11 and the second lens 21 can cooperate to realize imaging. According to the camera module 100 of the embodiment of the invention, on one hand, the first lens 11 and the second lens 21 are used for imaging independently or cooperatively, so that the requirement of freely switching multiple actual use scenes can be met; in another aspect, the driving component drives the first lens 11 to be movable between the first position and the second position, so that one or more lenses can be shared in multiple scenes without adding lenses, thereby avoiding assembling multiple corresponding lenses for multiple use scenes and saving the internal space of the camera module 100.
According to an embodiment of the present invention, as shown in fig. 1, the camera module 100 further includes a field lens 40, and the position of the imaging beam can be changed by the field lens 40. The field lens 40 is movable between a third position and a fourth position, the field lens 40 being coupled to and driven by the drive assembly. Under the condition that the field lens 40 is in the third position, the field lens 40 is located outside the imaging optical paths of the first lens assembly 10 and the second lens assembly 20, and does not interfere with the imaging optical paths of the first lens assembly 10 and the second lens assembly 20. Under the condition that the field lens 40 is in the fourth position, the field lens 40 is located on the imaging optical path of the second lens assembly 20 and cooperates with the first lens 11 and the second lens 21 to form an image.
Further, as shown in fig. 1, the first lens 11 is a telephoto lens, the second lens 21 is a wide-angle lens, and when the incident light passes through the wide-angle lens and the telephoto lens in sequence and forms an image cooperatively, the first lens 11 and the second lens 21 may become a part of a fresnel lens. The frazier lens is a secondary imaging system, and the wide-angle lens has a short focal length and can realize super-depth-of-field projection from three dimensions to two dimensions. A long-focus lens (with variable aperture and focal length and the same principle below) is connected behind the wide-angle lens to capture an enlarged and middle image surface, so that primary imaging can be changed into secondary imaging, and the effect of large depth of field is achieved.
That is to say, the camera module 100 according to the embodiment of the present invention can provide a combination of a wide-angle lens and a telephoto lens according to the frazier lens principle, so as to achieve a large depth of field. When the camera module 100 according to the embodiment of the invention is normally used at ordinary times, the wide-angle and telephoto functions can be independently realized, and when a picture with large depth of field needs to be shot, the relative positions of the wide-angle lens and the telephoto lens are changed through the driving assembly to form a Frazier lens mode, so that the shooting with large depth of field is realized. Therefore, according to the embodiment of the invention, the wide-angle lens and the telephoto lens can be utilized, the utilization rate of the camera with the specific function is improved, the shooting with large depth of field is realized, the long shot and the short shot are focused clearly at the same time, and the user experience is improved.
In some embodiments of the present invention, as shown in fig. 1, the field lens 40 is positioned between the first lens 11 and the second lens 21 with the field lens 40 in the fourth position. For convenience of description, a light incident side of the image capturing module 100 is referred to as a light incident side, and when the first lens 11 is a telephoto lens and the second lens 21 is a wide-angle lens, the incident light may sequentially pass through the second lens 21, the field lens 40, and the first lens 11 from the light incident side.
According to an embodiment of the present invention, as shown in fig. 1 and 2, the first lens assembly 10 further includes: and the first sensor 12 is used for cooperating with the first lens 11 to form an image under the condition that the first lens 11 and the second lens 21 are at the first position. The second lens assembly 20 further includes: and the second sensor 22, under the condition that the first lens 11 and the second lens 21 are at the first position, the second sensor 22 and the second lens 21 cooperate to form an image, and under the condition that the first lens 11 and the second lens 21 are at the second position, the field lens 40 is at the fourth position, the second sensor 22 cooperates with the first lens 11, the second lens 21 and the field lens 40 to form an image.
That is, when the first lens 11 is in the first position, the first lens 11 and the first sensor 12 cooperate to form an image, when the second lens 21 is in the first position, the second lens 21 and the second sensor 22 cooperate to form an image, and when the first lens 11 and the second lens 21 are in the second position, the first lens 11, the second lens 21 and the second sensor 22 cooperate to form an image. It should be noted that the first sensor 12 and the second sensor 22 may be prior art sensors, may be separate sensors, or may be sensors of an integrated structure, and the type thereof is not limited. The principle of operation of a sensor according to an embodiment of the invention is known to a person skilled in the art and will not be described in detail here.
Further, as shown in fig. 1 and 2, the driving assembly includes: the first driving member 31 is connected with the first lens 11 to drive the first lens 11, and the second driving member 32 is connected with the field lens 40 to drive the field lens 40. That is, the first lens 11 and the field lens 40 can be driven by the first driving member 31 and the second driving member 32, so that the first driving member 31 and the second driving member 32 can be arranged in space, and interference caused by movement of the first lens 11 and the field lens 40 can be avoided.
According to an embodiment of the present invention, as shown in fig. 2, under the condition that the first lens 11 and the second lens 21 are at the first position, the first lens 11 and the second lens 21 are arranged side by side, and the distance between the second lens 21 and the second sensor 22 is smaller than the axial length of the first lens 11. For convenience of description, the first lens assembly 10 and the second lens assembly 20 are set to extend in the up-down direction. When the first lens 11 and the second lens 21 are in the first position, the first lens 11 and the second lens 21 may be spaced apart in the left-right direction. When the first lens 11 is a telephoto lens and the second lens 21 is a wide-angle lens, the distance between the second lens 21 and the second sensor 22 is limited, so that the length of the first lens assembly 10 in the up-down direction and the length of the second lens assembly 20 in the up-down direction tend to be consistent, thereby facilitating the manufacturing and assembling.
In addition, the driving assembly further includes a third driving member 33, and the third driving member 33 is connected to the second sensor 22 to adjust the distance between the second sensor 22 and the second lens 21, so that not only the degree of automation can be improved, but also interference between the first lens 11 and the second sensor 22, which move between the second lens 21 and the second sensor 22, can be avoided.
Further, as shown in fig. 2, under the condition that the first lens 11 and the second lens 21 are at the first position, the first sensor 12 is disposed in parallel with the second sensor 22, and the driving assembly further includes: and a fourth driver 34, wherein the fourth driver 34 is connected with the first sensor 12 to adjust the distance between the first sensor 12 and the first lens 11, and prevent the first lens 11 from interfering with the first sensor 12 during the movement of the first lens 11.
In some embodiments of the present invention, as shown in fig. 1 and 2, the first lens assembly 10 further includes a first protective lens 13, and the first protective lens 13 is located at a light entrance end of the first lens 11 under the condition that the first lens 11 and the second lens 21 are at the first position. The second lens assembly 20 further includes a second protective lens 23, and the second protective lens 23 is located at the light inlet end of the second lens 21. That is, the first protective lens 13 is provided at the light entrance end of the first lens 11, and the second protective lens 23 is provided at the light entrance end of the second lens 21, so that dust and water can be prevented from entering the camera module 100. In addition, the first protective lens 13 and the second protective lens 23 may be transparent or translucent members to prevent light from being incident on the first lens and the second lens.
The operation of the image capturing module 100 according to the embodiment of the present invention will be described below by taking the first lens 11 as a telephoto lens and the second lens 21 as a wide-angle lens.
For convenience of description, the first lens assembly 10 and the second lens assembly 20 are set to extend in the up-down direction.
When the telephoto lens and the wide-angle lens are respectively at the first positions, the telephoto lens is positioned on the left side of the wide-angle lens, and the telephoto lens and the wide-angle lens are arranged side by side in the left-right direction. Light is incident from the light entrance side in the direction of the arrow in fig. 2. On one hand, the light can sequentially pass through the first protective lens 13 and the telephoto lens and converge to the first sensor 12, so that the telephoto lens shooting is realized. In another aspect, the light can sequentially pass through the second protective lens 23 and the wide-angle lens and converge to the second sensor 22, so as to realize wide-angle lens shooting. It should be noted that the first lens assembly 10 and the second lens assembly 20 may operate simultaneously or separately, and are not limited herein.
When the telephoto lens and the wide-angle lens need to be switched from the first position to the second position, the first sensor 12 is driven to move downward by the fourth driving member 34, and the second sensor 22 is driven to move downward by the third driving member 33. And the telephoto lens is driven to move towards the lower right by the first driving piece 31 until the telephoto lens moves below the wide-angle lens and above the second sensor 22, and the field lens 40 is driven to move towards the left between the wide-angle lens and the telephoto lens by the second driving piece 32. Finally, the image is received by the second sensor 22, i.e. the frazier lens mode shown in fig. 1 is implemented. The wide-angle lens has the characteristics of short focal length, large depth of field, close-range magnification and long-range reduction. The field lens 40 may be placed near the intermediate image and collect marginal rays, reduce vignetting, and magnify the intermediate image. The telephoto lens has a long focal length and amplifies the intermediate image.
When the telephoto lens and the wide-angle lens need to move from the second position to the first position, the telephoto lens is driven to move to the left upper side to the lower side of the first protective lens 13 by the first driving member 31, and the first sensor 12 is driven to move upward to the initial position by the fourth driving member 34, so that the telephoto lens mode is realized. Meanwhile, the field lens 40 is driven by the second driving member 32 to move rightward to the outside of the optical path of the wide-angle lens, and the second sensor 22 is driven by the third driving member 33 to move upward to the initial position, so that the wide-angle lens mode as shown in fig. 2 is realized.
