Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 8, an embodiment of the invention discloses a camera module, which includes a lens 300, a first photosensitive chip 400, a second photosensitive chip 500, a first fabry-perot interferometer 600, and a reflector 700.

The lens 300 is a light inlet device of the camera module, and the first photosensitive chip 400 and the second photosensitive chip 500 are photosensitive devices of the camera module. The light passing through the lens 300 can be projected to the first photosensitive chip 400 or the second photosensitive chip 500, and is finally sensed by the first photosensitive chip 400 or the second photosensitive chip 500.

The reflection member 700 is used to adjust the optical path. In the embodiment of the present invention, the reflection member 700 is disposed opposite to the lens 300, and during a specific working process, light entering the camera module through the lens 300 is projected onto the reflection member 700, and the direction of the light path is adjusted under the action of the reflection member 700. The type of the reflecting member 700 may be various, for example, the reflecting member 700 may be a plane mirror, a reflecting prism, or the like, and the embodiment of the present invention does not limit the specific type of the reflecting member 700.

In the embodiment of the present invention, the reflection member 700 is rotatably disposed on the mounting base, and the mounting base may be another component of the camera module (for example, a bracket 200 described later). The reflection member 700 is rotatably switched between a first position and a second position.

The first fabry-perot interferometer 600 includes a first lens and a second lens, the first lens and the second lens are spaced apart from each other, that is, a certain distance is provided between the first lens and the second lens, so that the first fabry-perot interferometer 600 is formed between the first lens and the second lens. In a specific design process, the cavity length of the first fabry-perot interferometer 600 can be changed by adjusting the distance between the first lens and the second lens, so that the first fabry-perot interferometer 600 can pass light rays of corresponding wavelength bands, that is, the first fabry-perot interferometer 600 plays a role in selecting frequencies or wavelengths for input non-monochromatic light. By changing the cavity length of the first Fabry-Perot interferometer 600, monochromatic light with different wavelengths can be screened out, and then the monochromatic light is induced after passing through the first Fabry-Perot interferometer 600, so that the effect of collecting spectral curve information is achieved. The operation and structure of the first fabry-perot interferometer 600 are well known in the art and will not be described herein.

In the embodiment of the present invention, the first fabry-perot interferometer 600 is disposed between the first photosensitive chip 400 and the reflecting member 700. Specifically, the first fabry-perot interferometer 600 may be mounted on the basis of other components of the camera module (such as the holder 200 or the base 100 described later).

As described above, the reflection member 700 may be in the first position and the second position. In a case where the reflecting member 700 is at the first position, the reflecting member 700 receives the light passing through the lens 300 and causes the light to be projected onto the first photosensitive chip 400 through the first fabry-perot interferometer 600, in which case the first photosensitive chip 400 senses the light passing through the first fabry-perot interferometer 600, thereby implementing multispectral photographing.

In a specific working process, light passing through the lens 300 is projected onto the reflector 700, then the reflector 700 reflects the light onto the first fabry-perot interferometer 600, the light is projected onto the first photosensitive chip 400 after passing through the first fabry-perot interferometer 600, and finally the first photosensitive chip 400 senses the light to perform shooting in one mode, wherein the shooting mode is a multispectral mode, so that multispectral collection is realized.

In the case that the reflecting member 700 is in the second position, the reflecting member 700 receives the light passing through the lens 300 and causes the light to be projected onto the second photo-sensing chip 500, in which case the second photo-sensing chip 500 senses the light passing through the lens 300 to perform another mode of photographing, which is a conventional photographing mode.

In a specific operation process, the light passing through the lens 300 is projected onto the reflection member 700, and then the reflection member 700 reflects the light onto the second photo sensor 500, and is finally sensed by the second photo sensor 500.

The camera module disclosed by the embodiment of the invention further comprises a reflector 700, a first Fabry-Perot interferometer 600, a first photosensitive chip 400 and a second photosensitive chip 500 by improving the structure of the existing camera module, during the specific image shooting process, multispectral shooting can be carried out by the camera module by adjusting the reflector 700 to be at the first position, and another mode of shooting can be carried out by the camera module by adjusting the reflector 700 to rotate to the second position, wherein the shooting mode is the conventional shooting mode of the camera module. The camera module with the structure can perfectly be compatible with the multispectral shooting technology while ensuring that the conventional imaging is not interfered, so that the camera module can carry out multispectral shooting, and the image presenting capability can be better improved.

The camera module disclosed by the embodiment of the invention is equivalent to function expansion of the camera module, and is beneficial to improving the shooting experience and satisfaction of users.

In order to improve the shooting performance, in a preferable scheme, the camera module disclosed in the embodiment of the present invention may further include an optical filter 800, and the optical filter 800 is disposed between the reflector 700 and the second photosensitive chip 500. The optical filter 800 can perform a filtering function, so that light not required by the second photosensitive chip 500 can be filtered, thereby preventing the second photosensitive chip 500 from forming a false color or a ripple, and further improving effective resolution and color reducibility of an image. In a specific photographing process, when the reflector 700 is at the second position, the light passing through the lens 300 is reflected by the reflector 700 and then is projected onto the optical filter 800, and the light is filtered by the optical filter 800 and finally is projected onto the second photosensitive chip 500.

In the embodiment of the present invention, the filter 800 may be of various types, for example, the filter 800 may be an infrared filter, and the infrared filter easily meets the filtering requirement of most users during the shooting process. Of course, the filter 800 may be other types of filters, and the embodiment of the invention does not limit the specific type of the filter 800.

In order to facilitate the arrangement of the optical filter 800, in a preferable embodiment, the optical filter 800 may be attached to the surface of the second photosensitive chip 500. Specifically, the optical filter 800 may be attached to the surface of the second photosensitive chip 500 by an optical adhesive layer. The adoption of the attaching mode can improve the installation stability of the optical filter 800, and meanwhile, the optical filter 800 is attached to the surface of the second photosensitive chip 500, so that the space occupied by the assembly of the optical filter 800 and the second photosensitive chip can be reduced, and the integration of more functional devices in the internal space of the camera module is facilitated.

In the embodiment of the present invention, the light sensing area of the first light sensing chip 400 and the light sensing area of the second light sensing chip 500 may be different or equal. The pixel size of the first photosensitive chip 400 and the pixel size of the second photosensitive chip 500 may not be equal or may be equal. In addition, the number of pixels of the first photosensitive chip 400 may not be equal to the number of pixels of the second photosensitive chip 500, or may be equal to each other. Under the condition that the parameters are not equal, more diversified image acquisition capacity of the camera module can be realized, so that more shooting requirements of users can be met more easily.

In a preferred embodiment, the pixel size of the first photosensitive chip 400 is larger than the pixel size of the second photosensitive chip 500, so that the sensitivity of the first photosensitive chip 400 to dark light is higher, which is beneficial to improving the application range of full spectrum, and further improving the shooting capability.

In the embodiment of the present invention, the kinds of the first and second

photosensitive chips

400 and 500 may be different. Specifically, one of the first and second

photosensitive chips

400 and 500 may be an IR photosensitive chip or a polarized light photosensitive chip. Specifically, the second photosensitive chip 500 may also be a real photosensitive chip. The embodiment of the present invention does not limit the specific kinds of the first and second

photosensitive chips

400 and 500.

In a general case, the camera module disclosed in the embodiment of the present invention further includes a base 100 and a bracket 200, wherein: the bracket 200 is disposed on the base 100; the first photosensitive chip 400, the second photosensitive chip 500, the first fabry-perot interferometer 600, and the reflection member 700 are all disposed in a space formed by the support 200 and the base 100, thereby achieving installation. The lens 300 may be fixed to the bracket 200 to achieve the installation of the lens 300, for example, the lens 300 may be fixed to the bracket 200 by means of adhesion. The arrangement of the base 100 and the support 200 makes the installation of the first photosensitive chip 400, the second photosensitive chip 500, the first fabry-perot interferometer 600 and the reflector 700 easier, and makes it easier to assemble the various components to meet the above optical requirements.

The reflection member 700 may be rotatably provided to the supporter 200 so as to be rotatably switched between the first position and the second position. The holder 200 not only can provide a mounting position for the lens 300, but also can enclose a space with the base 100, thereby protecting components disposed in the space.

In the embodiment of the present invention, the base 100 not only provides a mounting position for the bracket 200, but the base 100 generally includes a circuit board, in which case, both the first photosensitive chip 400 and the second photosensitive chip 500 can be electrically connected to the circuit board, so as to be powered by the circuit board. In this case, the base 100 can also function to supply power to the first and second

photosensitive chips

400 and 500. Specifically, the base 100 can be a substrate, so that a flat mounting surface can be provided for other components of the camera module, and the size of the whole camera module can be reduced.

In the embodiment of the present invention, the first photosensitive chip 400 and the second photosensitive chip 500 are generally oriented differently. The support 200 may also provide a mounting base for other members, and the first photosensitive chip 400 and the second photosensitive chip 500 are disposed on the support 200, and the respective orientations may be designed according to the shape of the support 200. In an alternative scheme, the first photosensitive chip 400 may be disposed on a first inner sidewall of the bracket 200, the second photosensitive chip 500 is disposed on a second inner sidewall of the bracket 200, and the first inner sidewall and the second inner sidewall may be disposed oppositely, so that the first photosensitive chip 400 and the second photosensitive chip 500 are located at opposite positions. Specifically, the first photosensitive chip 400 may be adhesively fixed on the first inner sidewall, and the second photosensitive chip 500 may be adhesively fixed on the second inner sidewall. Of course, the first inner sidewall and the second inner sidewall may also be two adjacent inner sidewalls in the rack 200.

For convenience of layout, in a preferred embodiment, the photosensitive surface of the first photosensitive chip 400 and the photosensitive surface of the second photosensitive chip 500 may be parallel to the axis of the lens 300. Of course, the photosensitive surface of the first photosensitive chip 400 and the photosensitive surface of the second photosensitive chip 500 are planar. Of course, the first photosensitive chip 400 and the second photosensitive chip 500 may have other orientations as long as the optical requirements described above are satisfied.

In a case where the photosensitive surface of the first photosensitive chip 400 and the photosensitive surface of the second photosensitive chip 500 are both parallel to the axis of the lens 300, in a more preferred embodiment, the reflecting member 700 may be a plane mirror, and an included angle between the plane mirror and the axis of the lens 300 may be 45 °. This particular embodiment is clearly advantageous for the arrangement of the reflecting member 700.

In order to facilitate the control of the rotation of the reflecting member 700, in a preferred embodiment, the first photosensitive chip 400 and the second photosensitive chip 500 may be symmetrically disposed on two sides of the axis of the rotating shaft of the reflecting member 700. In this case, the reflecting member 700 may be rotated in opposite directions by the same angle during the rotation, thereby achieving the switching between the first position and the second position.

In a preferable scheme, the camera module disclosed in the embodiment of the present invention may further include a zoom motor 900, the zoom motor 900 is disposed on the bracket 200, the zoom motor 900 is drivingly connected to the lens 300, and the zoom motor 900 may drive the lens 300 to move, so as to implement a zoom function, which undoubtedly can implement a stronger shooting performance. Specifically, the zoom motor 900 may be fixed to the bracket 200 by means of adhesion, thereby achieving installation. In the embodiment of the present invention, the zoom motor 900 may be a voice coil motor, and of course, the zoom motor may be of other types, and the embodiment of the present invention does not limit the specific type of the zoom motor 900.

In order to alleviate the problem that the lens 300 is easily damaged, the camera module disclosed in the embodiment of the present invention may further include a protective film 910, and the protective film 910 is disposed on the zoom motor 900 and covers the lens 300. The protective film 910 can certainly provide a good protection for the lens 300. Specifically, the protective film 910 may be disposed on the zoom motor 900 by vacuum adhesion or adhesion, thereby enabling more stable installation.

Under the premise that the first photosensitive chip 400 and the second photosensitive chip 500 are both parallel to the axis of the lens 300 and the included angle between the planar mirror and the axis of the lens 300 is 45 degrees, the initial state of the camera module can be set to be that the included angle between the planar mirror and the axis of the lens 300 is-45 degrees, in this case, the planar mirror is in the second position, and in this case, the second photosensitive chip 500 can perform photosensitive shooting; when multispectral shooting is required, the planar reflector can be controlled to rotate to +45 degrees, and under the condition, the planar reflector is located at the first position, so that the first photosensitive chip 400 performs photosensitive shooting.

During a specific operation, the reflection member 700 can be rotationally switched between the first position and the second position. In order to facilitate implementation, in a preferable scheme, the camera module disclosed in the embodiment of the present invention may further include a first driving module, and the first driving module is connected to the reflecting member 700. The first driving module drives the reflection member 700 to rotate and switch between the first position and the second position. Specifically, the first driving module may be a driving motor. The embodiment of the present invention does not limit the specific kind of the first driving module.

In the embodiment of the present invention, the first fabry-perot interferometer 600 is a known device, and the first fabry-perot interferometer 600 may include a first lens and a second lens, the first lens and the second lens are spaced apart from each other, and a distance between the first lens and the second lens is adjusted, so that light rays with different wavelengths can pass through the first lens and the second lens. Specifically, the first lens and the second lens may be fixed lenses, that is, the cavity length of the first fabry-perot interferometer 600 is a fixed value, in which case, the first fabry-perot interferometer 600 can only let light with corresponding wavelength pass through.

Certainly, in order to realize the adjustment in the use and select the monochromatic light that passes through in a flexible way, in the preferred scheme, first lens is movably set up on the inner space of the module of making a video recording or component, under this kind of circumstances, the user can adjust the position of first lens at any time in the in-process of using, and then changes the distance between first lens and the second lens, finally can adjust the wavelength of light, finally can make the light of different wavelengths pass through first fabry-perot interferometer 600. Note that the first mirror may be a mirror on the light entrance side of the first fabry-perot interferometer 600.

In order to facilitate adjustment, the camera module disclosed in the embodiment of the present invention may further include a second driving module, and the second driving module is connected to the first lens. The second driving module can drive the first lens to move towards the second lens or move away from the second lens. Specifically, the second driving module may be a hydraulic expansion member, a pneumatic expansion member, a linear motor, and the like, and the embodiment of the present invention does not limit the specific type of the second driving module. In a specific assembling process, the second driving module may be installed in an internal space of the camera module or on a component (e.g., the base 100 or the support 200 of the camera module), so as to drive the first lens to move.

Referring to fig. 3 to 5, in a more preferred embodiment, the image pickup module disclosed in the embodiment of the present invention may further include a second fabry-perot interferometer 920, and the second fabry-perot interferometer 920 is disposed between the reflection member 440 and the second photosensitive chip 500. On the premise that the camera module comprises the second Fabry-Perot interferometer 920, the cavity length of the first Fabry-Perot interferometer 600 and the cavity length of the second Fabry-Perot interferometer 920 can be unequal, so that spectrum information collection of different wave bands is realized.

In the case of including the second fabry-perot interferometer 920, the second light sensing chip 500 may include the first light sensing region 510 and the second light sensing region 520.

Referring to fig. 4 and 5 again, the second photosensitive area 520 and the first photosensitive area 510 are different photosensitive areas of the second photosensitive chip 500, and the second fabry-perot interferometer 920 is disposed in the second photosensitive area 520. In this case, the first photosensitive area 510 can perform a photographing in one mode, and the light projected to the second photosensitive area 422 passes through the second fabry-perot interferometer 920, so that the second photosensitive area 520 can perform a photographing in another mode. This can certainly improve the image acquisition capability.

When the reflector 700 is in the second position, the light passing through the lens 300 is reflected by the reflector 700 and directed to the second photosensitive chip 500, part of the light may be directly projected onto the first photosensitive area 510, and another part of the light may be projected onto the second photosensitive area 520 through the second fabry-perot interferometer 920.

Specifically, the pixel size of the first photosensitive region 510 and the pixel size of the second photosensitive region 520 may be equal, as shown in fig. 4. Of course, the pixel size of the first photosensitive region 510 and the pixel size of the second photosensitive region 520 may not be equal. Under the condition that the parameters are not equal, more diversified image acquisition capacity of the camera module can be realized, so that more shooting requirements of users can be met more easily.

In a preferable scheme, the pixel size of the second photosensitive region 520 may be larger than the pixel size of the first photosensitive region 510, as shown in fig. 5, so that the sensitivity of the second photosensitive region 520 to dark light is higher, which is beneficial to improving the use range of a full spectrum, and further improving the multispectral collection capability.

When the image capturing module includes the optical filter 800, the optical filter 800 covers the first photosensitive region 510 and avoids the second photosensitive region 520, thereby avoiding the influence on the second fabry-perot interferometer 920.

In the embodiment of the present invention, the first fabry-perot interferometer 600 and the second fabry-perot interferometer 920 may have the same or different structures. The first fabry-perot interferometer 600 includes a first lens and a second lens spaced apart from each other, and the second fabry-perot interferometer 920 includes a third lens and a fourth lens spaced apart from each other.

In a first specific embodiment, the first lens and the second lens are both fixed lenses, and the third lens and the fourth lens are both fixed lenses. In this case, neither the first fabry-perot interferometer 600 nor the second fabry-perot interferometer 920 can adjust the cavity length, thereby realizing the transmission of light rays of two different wave bands.

In a second specific embodiment, the first lens is a movable lens and can move towards the second lens or away from the second lens, and the third lens and the fourth lens are both fixed lenses. Under the condition, the cavity length of the first Fabry-Perot interferometer 600 is adjustable, and the cavity length of the second Fabry-Perot interferometer 920 is not adjustable, so that the flexibility of collocation between the first Fabry-Perot interferometer 600 and the second Fabry-Perot interferometer 920 can be improved, the transmission of more light rays with different wave bands is obtained, and the shooting performance of the camera module is improved.

In a third specific embodiment, the first lens and the second lens are both fixed lenses, and the third lens is a movable lens and can move towards or away from the fourth lens. Under the condition, the cavity length of the first Fabry-Perot interferometer 600 is not adjustable, and the cavity length of the second Fabry-Perot interferometer 920 is adjustable, so that the flexibility of collocation between the first Fabry-Perot interferometer 600 and the second Fabry-Perot interferometer 920 can be improved, the transmission of more light rays with different wave bands is obtained, and the shooting performance of the camera module is improved.

In a fourth specific embodiment, the first lens is a movable lens and is movable toward or away from the second lens, and the third lens is a movable lens and is movable toward or away from the fourth lens. Under the condition, the cavity lengths of the first Fabry-Perot interferometer 600 and the second Fabry-Perot interferometer 920 are adjustable, so that the flexibility of matching between the first Fabry-Perot interferometer 600 and the second Fabry-Perot interferometer 920 can be further improved, the light rays of more different wave bands can be transmitted, and the shooting performance of the camera module is improved.
