In the related art, zooming of a camera module in a process of shooting a target object is mainly divided into three modes, namely digital zooming, optical zooming and relay zooming, and the three modes are specifically as follows:

digital zooming: the software is used for judging the color of the periphery of the existing pixel, and the pixel added by a special algorithm is inserted according to the peripheral color condition, so that the area of each pixel in the picture is increased. Although this zoom method does not change the focal length of the lens, it has a large damage to the image quality.

Optical zooming: utilize the electric motor drive lens group in the module of making a video recording to remove to change the focus of the camera lens of the module of making a video recording, realize the long burnt shooting effect of harmless. The longer the lens of the camera module, the larger the variable physical range of the focal length, and the larger the zoom multiple. However, in the zoom system, when long-focus shooting is performed, the camera module needs to be provided with a sufficient length in the optical axis direction, and an electric motor needs to be arranged inside the camera module.

The relay type zoom is characterized in that a plurality of optical devices with different focal lengths are configured, and through the combination of the optical devices, the transformation of different zoom multiples such as 0.5x, 1x, 1.5x and the like is realized during shooting. The camera module can be configured into a periscopic camera module based on the zooming mode, and the zooming of higher times is realized on the premise of not increasing the thickness of the camera module. However, in practical applications, algorithm assistance is also required when the zoom magnification is changed, and thus continuous high-definition image quality cannot be obtained during the change of the zoom magnification.

Here, in order to solve above-mentioned problem, this application realizes making a video recording the electrodeless of module and zooming when the miniaturized design of module to make a video recording to the image quality of high definition is gathered based on the module of making a video recording.

A camera module and an electronic device according to an embodiment of the present application are described below with reference to fig. 1 to 11.

As shown in fig. 1 and 2, a camera module according to some embodiments of the present application includes: lens assembly 100, reflection assembly 200, adjustment assembly 300, and image capture assembly 400.

The reflection assembly 200 and the image collection assembly 400 are respectively disposed on the adjustment assembly 300, and light passes through the lens assembly 100, is reflected by the reflection assembly 200, and then reaches the image collection assembly 400.

Upon receiving a focusing input from a user, the adjusting unit 300 adjusts the relative positions of the reflection unit 200 and the image pickup unit 400 based on an input parameter of the focusing input to change the image distance of the camera module.

In practical applications, the camera module is installed on the electronic device, and the lens assembly 100 on the camera module is in communication connection with a controller on the electronic device. A user may give a focus input through a display screen on the electronic device to effect control of the adjustment assembly 300 to change the relative positions of the reflection assembly 200 and the image acquisition assembly 400. The present embodiment may give the input parameters of the focus input on the display screen based on the pressing of the virtual control or based on the input form such as sliding or stretching.

In the process of shooting a target object, the positions of the reflection assembly 200 and the image acquisition assembly 400 can be adjusted through the adjusting assembly 300 according to actual shooting requirements, so that the length of an optical path between the reflection assembly 200 and the image acquisition assembly 400 is changed, the image distance of the camera module is changed, and meanwhile, the lens assembly 100 is controlled to perform optical zooming, so that stepless zooming of the camera module can be realized.

Meanwhile, as the lens assembly 100 does not generate large volume change in the optical zooming process, the thickness of the camera module along the optical axis direction of the lens assembly 100 is small, and the camera module can realize stepless zooming with small volume.

In practical application, in order to realize the installation of the optical device in the camera module, the camera module of the embodiment of the present application is provided with a housing 500, and the housing 500 is provided with an opening 51 and an accommodating cavity 52 communicated with the opening 51.

In the present embodiment, the lens assembly 100 is disposed at the opening 51, and the reflection assembly 200, the adjustment assembly 300 and the image capturing assembly 400 are disposed in the accommodating cavity 52 respectively. The accommodating chamber 52 has a bottom wall 521, the optical axis of the lens assembly 100 is perpendicular to the bottom wall 521, and the adjusting assembly 300 is connected to the bottom wall 521.

Meanwhile, the adjusting assembly 300 shown in this embodiment may be an elastic member or a deformable mechanical member, and the adjusting assembly 300 can switch its own form under the action of an internal or external driving assembly, so as to adjust the relative position of the reflecting assembly 200 and the image capturing assembly 400.

In one example, the adjusting assembly 300 includes an annular elastic supporting member, the reflection assembly 200 and the image capturing assembly 400 are respectively mounted on the elastic supporting member, a telescopic driving member is mounted inside the elastic supporting member, or a telescopic driving member is mounted between the elastic supporting member and the housing 500, and the form of the elastic supporting member can be switched between the first state and the second state by changing the telescopic stroke of the telescopic driving member, so as to adjust the relative position of the reflection assembly 200 and the image capturing assembly 400.

In another example, the adjustment assembly 300 may be a mechanical member with multiple active degrees of freedom, and the mechanical member may be switched between different configurations based on the rotation of each active degree of freedom on the mechanical member, so that the reflection assembly 200 and the image capturing assembly 400 may change relative positions according to the switching of the configurations of the mechanical member when the reflection assembly 200 and the image capturing assembly 400 are respectively mounted on the mechanical member.

When the form of the adjusting assembly 300 is switched, at least one of the reflecting assembly 200 and the image capturing assembly 400 can adjust the posture thereof, so that the light can be reflected by the reflecting assembly 200 and then received by the image capturing assembly 400 after passing through the lens assembly 100.

In addition, it should be noted that the lens assembly 100 of the embodiment of the present application is a zoom lens known in the art. The zoom lens includes a plurality of lenses coaxially disposed, and when the optical path length between the zoom lens and the image capturing assembly 400 is changed, the zoom lens can adjust the distance between the lenses according to the change of the optical path length, so as to achieve optical zooming. Since the optical zooming of the zoom lens belongs to the well-known technology in the optical field, the detailed description is omitted here.

In some examples, the reflection assembly 200 of the embodiment of the present application may employ an optical device such as a reflection prism, a plane mirror, etc., and the reflection assembly 200 is used for reflecting the light transmitted from the lens assembly 100 so that the image capture assembly 400 receives the reflected light. One or more reflecting members 200 may be provided, and are not particularly limited thereto.

In order to ensure high imaging quality of the camera module, the plane precision of the reflecting surface on the reflecting component must be ensured, for example, the precision of the reflecting surface reaches the nanometer level, so as to reduce the distortion of the optical path as much as possible and ensure the quality of the reflected light.

In some examples, the present embodiment may specifically set an incident light path of the light collected by the lens assembly 100 and transmitted to the reflection assembly 200 to be perpendicular to a reflection light path of the light reflected by the reflection assembly 200.

The present embodiment is based on the above optical path design, and can define the reflection optical path on the plane parallel to the bottom wall 521 of the accommodating cavity 52, and this design not only facilitates adjusting the relative position between the image capturing assembly 400 and the reflection assembly 200 based on the adjusting assembly 300 to achieve stepless zooming of the camera module, but also facilitates reducing the thickness of the camera module in the optical axis direction of the lens assembly 100 as much as possible, and achieves a miniaturized design of the camera module.

In some embodiments, as shown in fig. 1, 2, and 7, a reflective assembly 200 of embodiments of the present application includes a first reflective assembly 201; the first reflection assembly 201 is arranged opposite to the image acquisition assembly 400, and the adjusting assembly 300 is used for adjusting the relative positions of the first reflection assembly 201 and the image acquisition assembly 400; in the case where the input parameters of the focus input satisfy the first preset condition, the light passes through the lens assembly 100, is reflected by the first reflection assembly 201, and then reaches the image capture assembly 400.

In this embodiment, the first reflection assembly 201 is disposed at the first position P1 on the adjustment assembly 300, and the image capturing assembly 400 is disposed at the second position P2 on the adjustment assembly 300.

In actual arrangement, since the lens assembly 100 is usually fixedly disposed in the opening 51, in order to ensure that the reflecting surface of the first reflecting assembly 201 can receive incident light from the lens assembly 100, the present embodiment may set the first position P1 on the adjusting assembly 300 to be kept unchanged relative to the position of the housing 500.

In order to facilitate the adjustment of the relative positions of the reflection assembly 200 and the image capturing assembly 400 according to the adjustment assembly 300, the adjustment assembly 300 of the embodiment of the present application is provided with at least a first state and a second state; with the adjustment assembly 300 in the first state, the first position P1 is spaced a first distance from the second position P2; with the adjustment assembly 300 in the second state, the first position P1 is spaced a second distance from the second position P2, the first distance being less than the second distance.

When the form of the adjusting assembly 300 is switched between the first state and the second state, the second portion P2 of the adjusting assembly 300 is movable along a linear path or an arc path relative to the first portion P1 of the adjusting assembly 300, so that the position of the image capturing assembly 400 relative to the first reflecting assembly 201 is changed, thereby realizing stepless zooming of the camera module.

Further, when the relative position between the first reflection assembly 201 and the image capturing assembly 400 is changed, in order to ensure that the image capturing assembly 400 can receive the reflected light from the first reflection assembly 201, not only the orientation of the reflection surface of the first reflection assembly 201 relative to the image capturing assembly 400 can be adjusted, but also the orientation of the capturing end of the image capturing assembly 400 relative to the first reflection assembly 201 can be adjusted.

Of course, when the image capturing assembly 400 and the first reflection assembly 201 are kept in the same posture and are close to each other or far from each other, since the image capturing assembly 400 can stably receive the reflected light from the first reflection assembly 201, there is no need to adjust the orientation of the reflection surface of the first reflection assembly 201 or the capturing end of the image capturing assembly 400.

In some embodiments, as shown in fig. 1 and 2, the reflective element 200 of embodiments of the present application includes at least one second reflective element 202; the adjustment assembly 300 is used to adjust the relative position of the at least one second reflective assembly 202 and the first reflective assembly 201. Under the condition that the input parameters of the focusing input meet a second preset condition, light rays are reflected by the first reflection assembly 201 after passing through the lens assembly 100, then reflected by the at least one second reflection assembly 202, and then reach the image acquisition assembly 400.

The at least one second reflective element 202 may be disposed at other positions on the adjusting element 300 except for the first position P1 and the second position P2.

In practical applications, an appropriate number of second reflective assemblies 202 can be selected to reflect the light from the first reflective assembly 201 according to the shooting requirements.

In one example, after passing through the lens assembly 100, the light rays may pass through any one of the plurality of second reflective assemblies 202 after being reflected by the first reflective assembly 201, and then reach the image capture assembly 400.

In another example, after passing through the lens assembly 100, the light rays are reflected by the first reflecting assembly 201, and then sequentially reflected by at least two of the second reflecting assemblies 202, and then reach the image capturing assembly 400.

Further, in a situation that the second reflection assembly 202 is provided with a plurality of second reflection assemblies 202, the plurality of second reflection assemblies 202 may be disposed at two sides of a connection line between the first reflection assembly 201 and the image capturing assembly 400, so that light rays can reach the image capturing assembly 400 directly by reflection of the first reflection assembly 201 after passing through the lens assembly 100, and can reach the image capturing assembly 400 after sequentially passing through the first reflection assembly 201 and the second reflection assembly 202.

The first reflection assembly 201 is disposed at a connection position of the first adjustment arm 31 and the fourth adjustment arm 34, and the image capturing assembly 400 is disposed at a connection position of the second adjustment arm 32 and the third adjustment arm 33.

Based on the characteristics that the first adjusting arm 31, the second adjusting arm 32, the third adjusting arm 33 and the fourth adjusting arm 34 are sequentially hinged end to end, the adjusting assembly 300 can realize switching of multiple forms, so that the first reflecting assembly 201 and the image capturing assembly 400 can be close to or far away from each other.

In practical applications, the first adjusting arm 31, the second adjusting arm 32, the third adjusting arm 33, and the fourth adjusting arm 34 may further form a deformable parallelogram frame, and adjacent two of the first adjusting arm 31, the second adjusting arm 32, the third adjusting arm 33, and the fourth adjusting arm 34 may have the same length or different lengths, which is not particularly limited.

In order to allow the adjustment assembly 300 to have a relatively large adjustment margin and flexibility of adjustment, the present embodiment may provide that adjacent two of the first, second, third, and fourth adjustment arms 31, 32, 33, and 34 have the same length, so that the adjustment assembly 300 is formed as a deformable diamond frame.

Further, the present embodiment may also rotatably connect the end of the adjusting assembly 300, on which the first reflecting assembly 201 is mounted, with the housing 500, so that the adjusting assembly 300 has a greater adjusting margin.

During the switching of the adjusting assembly 300, the third position P3 and the fourth position P4 are close to or far away from each other, so that the position of the second reflecting assembly 202 relative to the first reflecting assembly 201 or the image capturing assembly 400 can be changed based on the arrangement of the second reflecting assembly 202, so as to adjust the length of the reflected light path from the first reflecting assembly 201 to the image capturing assembly 400.

As shown in fig. 8, when the image capture module captures a target object at a second shooting distance, the second shooting distance is set to be suitable for a short-distance shooting scene, in which case, the user can configure the input parameters of the focus input as the second input parameters according to the second shooting distance to increase the image distance of the image capture module on the basis of the embodiment shown in fig. 7.

When a user inputs a second input parameter to the display screen of the electronic device, the adjusting assembly 300 controls the first portion P1 and the second portion P2 to gradually get away from each other, so as to increase the reflection light path between the first reflecting assembly 201 and the image capturing assembly 400, and increase the image distance of the camera module.

As shown in fig. 9, when the image pickup module picks up an image of the target object at the third shooting distance, the third shooting distance is set to be suitable for the middle-distance shooting scene.

For this, the user may configure the input parameter of the focus input as the third input parameter according to the third photographing distance. When a user inputs a third input parameter to the display screen of the electronic device, if the first position P1 and the second position P2 on the adjustment assembly 300 reach the second distance and the adjustment assembly 300 is in the second state, the adjustment assembly 300 adjusts the distance between the third position P3 and the fourth position P4, and the orientations of the reflective surface on the reflective assembly 200 and the capturing end on the image sensor 41 are also adaptively adjusted, so that the adjustment assembly 300 is in the third state, and thus light rays are reflected by the first reflective assembly 201, the second reflective assembly i and the second reflective assembly ii in sequence after passing through the lens assembly 100 and then are received by the image capturing assembly 400.

In the process of changing the adjusting assembly 300 between the above two conditions, the equivalent image distance of the camera module when the adjusting assembly 300 is in the second state is equal to the equivalent image distance of the camera module when the adjusting assembly 300 is in the third state, so as to achieve stepless zooming of the camera module.

As shown in fig. 10, when the image capture module captures a target object at a fourth shooting distance, the fourth shooting distance is set to be suitable for a long-distance shooting scene, in this case, the user can configure the input parameters of the focus input as fourth input parameters according to the fourth shooting distance to increase the image distance of the image capture module on the basis of the embodiment shown in fig. 9.

As shown in fig. 10, when the user inputs the fourth input parameter to the display screen of the electronic device, the adjusting assembly 300 controls the first portion P1 to be close to the second portion P2, so that the distance between the second reflecting assembly i and the second reflecting assembly ii gradually increases. At this moment, light passes through behind the camera lens subassembly 100, passes through the reflection of first reflection subassembly 201, second reflection subassembly I and second reflection subassembly II in order, and when being received by image acquisition subassembly 400 again, at this in-process, the optical path length of the module of making a video recording increases to the increase of the image distance of the module of making a video recording is realized.

As shown in fig. 11, when the image capture module captures a target object at a fifth capture distance, setting the fifth capture distance is suitable for an ultra-long distance capture scene, in which case, the user may configure the input parameters of the focus input as fifth input parameters according to the fifth capture distance to increase the image distance of the image capture module on the basis of the embodiment shown in fig. 10.

When the user inputs the fifth input parameter to the display screen of the electronic device, the distance between the first part P1 and the second part P2 on the adjusting assembly 300 reaches the first distance, and at this time, the optical path length of the camera module reaches the maximum, so that the image distance of the camera module increases to the maximum.

Therefore, as the lens assembly does not generate large volume change in the optical zooming process, the thickness of the camera module along the optical axis direction of the lens assembly 100 is small, and the camera module can realize stepless zooming with small volume.
