The following describes a camera assembly 100, an electronic device 200, a photographing method of the electronic device, a photographing apparatus of the electronic device, and a readable storage medium according to an embodiment of the present application with reference to fig. 1 to 13.

As shown in fig. 1 and 2, the present application provides a camera assembly 100 comprising: an imaging element 120; a plurality of lens groups 110 disposed at one side of the imaging element 120, the lens groups 110 forming an imaging area 122 on the imaging element 120, the imaging areas 122 of adjacent lens groups 110 having an overlapping area 124.

Specifically, the camera assembly 100 includes an imaging element 120 and a plurality of lens groups 110, the plurality of lens groups 110 are disposed at one side of the imaging element 120, and each lens group 110 is capable of forming an imaging region 122 on the imaging element 120, that is, each lens group 110 is capable of performing photographing through the same imaging element 120, and imaging regions 122 formed on the imaging element 120 by adjacent lens groups 110 have an overlapping region 124, so that when photographing using a single lens, the area of the imaging region 122 can be increased as much as possible, and since the imaging regions 122 formed by adjacent lenses have overlapping portions, the miniaturization of the imaging element 120 can be facilitated, and therefore, a balance is achieved between the imaging area and the volume of the camera assembly 100, that is, the imaging area is increased, and the volume of the whole camera is reduced.

The number of the lens groups 110 may be 2, 3, 4, 5, 6, 7 or 8.

The lens groups 110 may be arranged in a single row, multiple rows, or distributed in an array, or a portion of the lens groups 110 may be arranged around another portion of the lens groups 110.

The light is irradiated on the imaging element 120 by refraction of the lens group 110 to form an image, and the area occupying the imaging element 120 is an imaging area 122. At least light irradiated on the imaging element 120 through the adjacent lens group 110 is located in the same region on the imaging element 120, which is the overlapping region 124. Thereby compressing the entire volume of the imaging element 120 and enlarging the imaging area of the individual lens group 110.

The included angle between the marginal light paths formed by the adjacent lens groups 110 is greater than 0 degree.

That is, after passing through the lens groups 110, the light is transmitted in a tapered light beam manner, the portion of the two adjacent lens groups 110 facing the light beam is an edge light path, and an acute angle is formed between the two edge light paths, so as to ensure that the edge light path formed by one lens group 110 irradiates on the imaging area 122 of the other lens group 110, thereby realizing the overlapping of the imaging areas 122 of the adjacent lens groups 110. That is, the camera assembly 100 forms a multi-channel form, images of multiple channels are imaged on the imaging element 120 of the same outsole through the relay lens group 110 and the module, and an overlapping area 124 exists between two adjacent lens groups 110.

The camera assembly 100 is further compatible with the large-pixel and large-bottom imaging element 120, so that the pixel area of the imaging element 120 is increased, and the light sensitivity is improved, thereby obtaining better image quality and definition and being more beneficial to shooting night scenes.

Moreover, the use of one imaging element 120 can be compatible with various functional modes of main shooting, ultra-wide angle and portrait, and if the number of pixels is high enough, the imaging element can also be compatible with high-magnification digital zooming, so that the overall volume of the camera assembly 100 is reduced, and after the camera assembly 100 is applied to the electronic device 200, the whole space of the electronic device 200 can be efficiently utilized to realize the desired shooting capability.

As shown in fig. 3, the 3 lens groups 110 are side by side for illustration, wherein the dotted line represents the imaging channel, the imaging channels of the adjacent lens groups 110 are partially overlapped, and there is an overlapping area between the imaging areas 122 formed on the imaging element 120 by the adjacent lens groups 110.

As shown in fig. 4, two imaging regions are formed on the imaging element, one of which is the imaging region 122a, the other of which is the imaging region 122b, and the imaging region 122a and the imaging region 122b have an intersection, that is, an overlapping region.

As shown in fig. 3, as a possible embodiment, the optical axes of the adjacent lens groups 110 form an acute included angle, and the adjacent lens groups 110 have a coincident portion. As shown in fig. 3, taking 3 lens groups 110 side by side as an example for explanation, the optical axes of the 3 lens groups 110 are O1, O2 and O3, O1 and O2 are adjacent, O2 and O3 are adjacent, an acute angle is formed between O1 and O2, and an acute angle is formed between O2 and O3. Also, each lens group 110 forms an imaging channel, and as shown in fig. 3 by the dotted lines, the field of view directions of adjacent imaging channels have partial coincidence, which is shown in fig. 3 as the dotted lines intersect.

Specifically, the adjacent lens groups 110 are arranged obliquely, so that the optical axes of the adjacent lens groups 110 form an included angle, a reflective element and the like are not required to be arranged, the volume of the camera assembly 100 is reduced, a plurality of lenses are more concentrated, one imaging element 120 can correspond to more lens groups 110, the inclination of the lenses is reduced, and image distortion generated at the edge of the lens groups 110 can be reduced.

Wherein, the included angle between the optical axes of the adjacent lens groups 110 is equal to 80 degrees, 75 degrees, 60 degrees, 45 degrees, 30 degrees or 15 degrees, etc.

Moreover, when the images are shot at the same position, the images shot by different lens groups 110 are associated with each other, and have overlapped parts, so that the images can be spliced into one image, and the content of the image is enriched, so that the image can bear more information.

Specifically, when the ultra-wide-angle imaging function is used, the imaging of the plurality of lens groups 110 can be performed in a mosaic manner, and a smaller distortion, i.e., a small scene edge deformation, such as: the final imaging full field of view is 120 deg., the imaging field of view of each lens group 110 can be in the range of 40 deg. to 45 deg., and the field angle in this range is easily controlled for one lens group 110 to be distorted.

The camera assembly 100 has a compact overall structure, high integration degree and high reliability.

Further, the view fields of the adjacent lens groups 110 are partially overlapped, and then after shooting, part of scenes on the images formed by the adjacent lens groups 110 are overlapped, so that the images are cut and fused conveniently, and the possibility of losing materials on the shot images is reduced.

As shown in fig. 1 and 2, taking an example having two lens groups, i.e., a lens group 110a and a lens group 110b, the lens group 110a and the lens group 110b are inclined to each other as shown by the dotted lines in fig. 1 and 2, the imaging channels of the two intersect, and an imaging region and an overlapping region are formed on the imaging element.

As shown in fig. 1, 2 and 5, as a possible embodiment, the camera head assembly 100 further includes: the cover plate 130 is disposed on a side of the lens groups 110 away from the imaging element 120, the cover plate 130 is provided with a plurality of through holes 132, and the plurality of through holes 132 are in one-to-one correspondence with the plurality of lens groups 110.

Specifically, the cover plate 130 is disposed on a side of the lens group 110 away from the imaging element 120, the cover plate 130 can protect the lens group 110 and the imaging element 120, and the cover plate 130 is provided with a through hole 132 corresponding to the lens group 110, so as to improve the imaging resolution.

The size and area of each through hole 132 on the cover plate 130 are the same, and the whole is rotationally symmetrical, so that each lens group 110 is opposite to the through hole 132, and the influence on the imaging quality caused by refraction is reduced.

The number of the through holes 132 on the cover plate 130 is the same as that of the lens groups 110, and is 2, 3, 4, 5, 6, 7 or 8.

The cover plate 130 may be made of plastic, glass, or other polymers.

As shown in fig. 5, as a possible embodiment, the cover plate 130 has a circular convex hull structure.

Specifically, the cover plate 130 adopts a circular convex hull structure, so that the cover plate 130 is more attractive, the cover plate 130 has better pressure bearing capacity, and the possibility of damage to the cover plate 130 is reduced. Moreover, an acute included angle is formed between the optical axes of the adjacent lens groups 110, and the cover plate 130 of a curved surface structure or a polygonal surface structure is more suitable for the plurality of lens groups 110, so that the space occupation of the cover plate 130 can be reduced, and the volume of the camera assembly 100 can be reduced.

Wherein, the round convex hull structure can be understood as a shape of a half sphere after a sphere is truncated. Alternatively, the round convex hull structure can be understood as a structure with a convex curved surface on the front surface and a concave curved surface on the back surface, for example: the front surface is a convex spherical surface in the first direction, the back surface is a concave spherical surface in the first direction, and the curvatures of the front surface and the front surface may be equal or different.

As shown in fig. 1 and 2, as one possible embodiment, the lens group 110 is disposed to be inclined with respect to the imaging element 120.

Specifically, the lens group 110 has a certain inclination angle with respect to the imaging element 120, so that the thickness of the camera assembly 100 is reduced without adding an optical path deflecting element in the subsequent imaging process.

Moreover, since the cover plate 130 is a circular convex hull structure, and the through hole 132 formed in the cover plate 130 is inclined, in the subsequent imaging process, there is no need to add an optical path turning element, which is beneficial to reducing the thickness of the camera assembly 100 and realizing miniaturization in the direction from the imaging element 120 to the cover plate 130 as much as possible.

Since the through holes 132 and the lens groups 110 are in a one-to-one correspondence relationship, the through holes 132 are also disposed in an inclined manner with respect to the imaging element 120.

Moreover, the size of the inclination angle of the lens group 110 and the imaging element 120 is related to the radius of the cover plate 130, the larger the radius of the cover plate 130 is, the smaller the inclination angle between the lens group 110 and the imaging element 120 is, the smaller the radius of the cover plate 130 is, and the larger the inclination angle between the lens group 110 and the imaging element 120 is.

Specifically, as shown in fig. 1 and 2, when the number of the lens groups 110 is two, the distance from the opposite side of the two lens groups 110 to the imaging element 120 is greater than the distance from the opposite side of the two lens groups 110 to the imaging element 120, so that the imaging channels of the two lens groups 110 intersect and an imaging region 122 and an overlap region 124 are formed on the imaging element 120.

When the number of the lens groups 110 is more than 2, the plurality of lens groups 110 are disposed around a center position, and a distance from a side of the plurality of lens groups 110 facing the center position to the imaging element 120 is greater than a distance from a side of the plurality of lens groups 110 facing away from the center position to the imaging element 120, so that imaging channels of the plurality of lens groups 110 intersect and an imaging region 122 and an overlapping region 124 are formed on the imaging element 120.

As shown in fig. 3, as a possible implementation, an included angle between optical axes of adjacent lens groups 110 is greater than or equal to an angle of view of the lens groups 110.

Specifically, since the optical axes of the lens groups 110 are usually located at the axial center of the lens groups 110, if the included angle between the optical axes of the adjacent lens groups 110 is too small, the lens groups 110 interfere with each other, and the imaging is affected, and the included angle between the optical axes of the adjacent lens groups 110 is set to be greater than or equal to the viewing angle of the two lens groups 110, so as to prevent the two lens groups 110 from overlapping.

Wherein, the angles of view of the plurality of lens groups 110 are the same or different, and when the angles of view of the plurality of lens groups 110 are different, the included angle between the optical axes of the adjacent lens groups 110 is set to be greater than or equal to the angle of view of each of the two lens groups 110.

Specifically, as shown in fig. 3, an angle Δ represents an included angle formed by edges of imaging channels of adjacent lens groups 110, so as to form an overlapping region on the imaging element 120, and can provide a basis for image processing, wherein the angle Δ is greater than 0 degree.

The angle of view 2 θ of the single lens group 110 is based on the field angle of the mobile phone to the subject. The angle W between the optical axes of the adjacent lens groups 110 is equal to or greater than 2 θ, so that no mechanical conflict between the lens groups 110 is satisfied.

In which the arrangement of the camera head assembly 100 is more compact and the number and area of the overlapping regions 124 may be increased by reducing the included angle between the optical axes of the adjacent lens groups 110.

When the lens groups 110 are arranged compactly, the included angle W between the adjacent lens groups 110 can be equal to the viewing angle 2 θ of a single lens group 110.

It can be seen from fig. 3 that when the lens groups 110 are closely arranged, the included angle between the optical axes of the adjacent lens groups 110 is equal to the taper angle 2 θ of the single lens group 110.

As a possible implementation, as shown in fig. 1, the camera head assembly 100 further includes: a carrier 140 on which the plurality of lens groups 110 are disposed; a first driving mechanism 150 connected to the carrier 140 for driving the carrier 140 to move; or as shown in fig. 2, the camera assembly 100 further includes: the lens groups 110 are disposed on the second driving mechanism 160, and the plurality of lens groups 110 correspond to the plurality of second driving mechanisms 160 one by one.

Specifically, the camera head assembly 100 further includes a carrier 140 and a first driving mechanism 150, the plurality of lens groups 110 are disposed on the carrier 140, and the first driving mechanism 150 is connected to the carrier 140, so that the first driving mechanism 150 can drive the carrier 140 to move, and the carrier 140 drives the plurality of lens groups 110 to move, thereby adjusting the focal lengths of the plurality of lens groups 110.

Alternatively, the camera head assembly 100 further includes second driving mechanisms 160, the lens groups 110 are correspondingly connected to the second driving mechanisms 160, and one second driving mechanism 160 can drive one lens group 110 to move, so as to realize independent zooming of each lens group 110.

As shown in fig. 1 and 2, as a possible embodiment, the lens groups 110 include diaphragms, and the diaphragms of different lens groups 110 are opened and closed in time series based on the photographing of the plurality of lens groups 110.

Specifically, each lens group 110 includes a stop, and since the adjacent lens groups 110 have an overlapping area 124 in the imaging area 122 of the imaging element 120, if a plurality of lens groups 110 are imaged simultaneously, the image portion is lower than the overlapping phenomenon of the scenes, so that the stop is set to open the stop of one lens group 110 and close the stops of the other lens groups 110 when shooting through the one lens group 110, thereby enabling normal shooting.

When a plurality of lens groups 110 are used for shooting, the diaphragms of different lens groups 110 are opened and closed in time sequence, that is, a plurality of cameras perform time sequence imaging, so that each image is complete and has no abnormality.

Moreover, because the angles of each lens group 110 are different, the images can be formed in a certain view field range, and then a plurality of images can be spliced to obtain a larger and wider view field range.

The diaphragm is mainly used for controlling the opening and closing of the imaging channel, and specifically can be a mechanical diaphragm, a liquid crystal sheet modulation diaphragm or a black-and-white liquid filling modulation liquid diaphragm.

In the mode of accommodating a plurality of lens groups 110 to capture images, the overall processing speed is related to the refreshing speed of the diaphragms on all the lens groups 110, the higher the refreshing frequency is, the smaller the flicker feeling of the images on the screen of the electronic device 200 is, the higher the stability is, and the protection of eyesight can be improved.

The refresh rate of the apertures of all lens groups 110 is greater than or equal to 75Hz, so as to reduce the flickering on the screen of the electronic device 200.

As shown in fig. 1 and 2, taking an example with two lens groups 110 as an illustration, namely a lens group 110a and a lens group 110b, the lens group 110a and the lens group 110b are inclined to each other, wherein the lens group 110a includes a diaphragm 112a, and the lens group 110b includes a diaphragm 112b, as shown by the dotted lines in fig. 1 and 2, the imaging channels of the two intersect and form an imaging region 122 and an overlapping region 124 on the imaging element 120, the diaphragm 112a can control the opening or closing of the imaging channel of the lens group 110a, and the diaphragm 112b can control the opening or closing of the imaging channel of the lens group 110 b.

As a possible implementation, the plurality of lens groups 110 are distributed in a rotational symmetry.

Specifically, the plurality of lens groups 110 are distributed in a rotationally symmetric manner, so that the plurality of lens groups 110 are more concentrated, the volume of the camera assembly 100 is reduced, and an image captured by the plurality of lens groups 110 can cover a larger area, thereby improving the capturing effect, and being capable of matching various working modes.

Wherein, the plurality of lens groups 110 can rotate 30 degrees, 45 degrees, 75 degrees, 90 degrees, 180 degrees and then return to the same structure as the plurality of lens groups 110.

The camera assembly 100 is illustrated as including 5 lens groups 110. The 4 lens groups 110 surround the periphery of 1 lens group 110, and if only the central lens group 110 is used for opening imaging, the main shooting function of the electronic device 200 can be matched; if all the lens groups 110 are used for imaging, the image fusion generates a wide-angle effect; since the peripheral lens groups 110 are inclined with respect to the central lens group 110, the focal lengths of the peripheral lens groups 110 are longer than the focal length of the central lens group 110, and therefore, the focal lengths of the peripheral lens groups 110 are one to two times of the focal length of the central lens group 110, and the image is melted to achieve the effect of human image; after shooting through a single lens group 110, the image can be digitally zoomed, cut and enlarged to obtain a telephoto effect.

As shown in fig. 1 and 2, as a possible embodiment, an optical filter 170 is disposed between the imaging element 120 and the lens group 110, a circuit board 176 is disposed at the bottom of the imaging element 120, the lead-out guide of the circuit board 176 is electrically connected to the first driving mechanism 150 or the second driving mechanism 160, and is also electrically connected to the diaphragm, and further includes a housing and the like, and the circuit board 176, the imaging element 120, the lens group 110, the cover plate 130, the first driving mechanism 150, and the second driving mechanism 160 are disposed on the housing.
