This is a reference diagram illustrating the shooting screen of the following camera module.

The camera module according to an embodiment of the present invention can be applied to portable electronic devices such as mobile communication terminals, smart phones, and tablet PCs.

First, referring to FIGS. 1 and 2, a camera module according to an embodiment of the present invention includes a lens assembly 100, a housing 200, a case 300, and an image sensor module 400.

The lens assembly 100 includes a plurality of lens modules. Each of the plurality of lens modules has an optical axis, and the optical axes of neighboring lens modules may be arranged in parallel.

A plurality of lens modules may be arranged in an n×n matrix structure or may be arranged in an n×m matrix structure. n and m are each different natural numbers of 2 or more.

Below, for convenience of explanation, an embodiment in which a plurality of lens modules are arranged in a 2×2 matrix structure will be described. For example, the plurality of lens modules include a first lens module 110, a second lens module 130, a third lens module 150, and a fourth lens module 170.

The focal length deviation of the plurality of lens modules may be within ±0.03mm, the angle of view deviation may be within ±3°, and the distortion deviation may be ±3°.

Lens assembly 100 is accommodated in housing 200. The camera module may be equipped with focusing and/or shake compensation functions.

For example, the lens assembly 100 may be moved in the optical axis direction with respect to the housing 200 to adjust focus. Additionally, the lens assembly 100 may be moved in a direction perpendicular to the optical axis with respect to the housing 200 to correct shake. Here, the optical axis direction may mean a vertical direction based on FIGS. 1 and 2.

To this end, the camera module according to an embodiment of the present invention may further include an actuator for moving the lens assembly 100.

The case 300 is combined with the housing 200 and may be configured to protect the internal structure of the camera module.

An image sensor module 400 may be coupled to the housing 200. The image sensor module 400 includes an image sensor 410 and a printed circuit board 430 to which the image sensor 410 is connected. Here, the image sensor 410 is provided as one image sensor 410.

That is, the lens assembly 100 includes a plurality of lens modules, and the image sensor module 400 does not include a plurality of image sensors corresponding to each lens module, but one through which light passing through each lens module is received. It includes an image sensor 410.

The position at which light passing through each lens module is received by one image sensor 410 is different. For example, the position where the light passing through the first lens module 110 is received, the position where the light passing through the second lens module 130 is received, the position where the light passing through the third lens module 150 is received, and The positions at which light passing through the fourth lens module 170 is received are different.

Referring to FIGS. 3 and 4 , the camera module according to an embodiment of the present invention can generate one complete image by combining images captured by a plurality of lens modules.

Referring to FIG. 3, the subject to be photographed is divided, each lens module captures each image, and the divided and photographed images are combined to create one complete image.

For example, the first lens module 110 captures the first image I1 corresponding to the first area of the photographing target, and the second lens module 130 captures the second image (I1) corresponding to the second area of the photographing target. I2), the third lens module 150 captures the third image I3 corresponding to the third area of the subject, and the fourth lens module 170 captures the third image I3 corresponding to the fourth area of the subject. The fourth image (I4) is taken.

Then, the first image (I1) to the fourth image (I4) are combined to create one complete image representing the photographing target.

Since one lens module does not photograph the entire object to be photographed, the lens module can be miniaturized compared to the case where one lens module photographs the entire object to be photographed. For example, the number of lenses included in each lens module of the camera module according to an embodiment of the present invention is smaller than when one lens module corresponds to one image sensor.

Therefore, the camera module according to an embodiment of the present invention divides the subject to be photographed and composites the divided images, thereby making it possible to miniaturize the camera module while using the image sensor 410 with a large number of pixels and a large size.

Referring to FIG. 4, a plurality of lens modules can each photograph the same object and combine the photographed images to create one complete image.

For example, the first to fourth lens modules 110 to 170 each photograph the same subject to generate first to fourth images I1 to I4.

Then, the first image (I1) to the fourth image (I4) are combined to generate one image with higher resolution than the individual images.

Therefore, the camera module according to an embodiment of the present invention combines images captured by multiple lens modules, allowing the camera module to be miniaturized while using an image sensor 410 with a large number of pixels and a large size.

Figure 5 is a plan view of a lens assembly according to an embodiment of the present invention, Figure 6 is a schematic exploded perspective view of a lens assembly according to an embodiment of the present invention, and Figures 7A to 7C are lens modules included in the lens assembly. This is a perspective view showing from various angles.

FIG. 8 is a plan view of a lens having a non-circular planar shape, FIG. 9 is a perspective view of the first to fourth lens modules, and FIG. 10 is a diagram schematically showing the arrangement of the lens assembly and the image sensor.

First, referring to FIGS. 5 and 6, the lens assembly 100 according to an embodiment of the present invention includes a first lens module 110, a second lens module 130, a third lens module 150, and a third lens module 150. It includes 4 lens modules 170 and further includes a lens holder 190.

Each lens module includes at least one lens and a lens barrel. At least one lens is disposed inside the lens barrel. When a plurality of lenses are provided, the plurality of lenses are mounted inside the lens barrel along the optical axis.

The first to fourth lens modules 110 to 170 are fixedly placed inside the lens holder 190.

Unlike an embodiment of the present invention, in order to create one complete image by dividing and photographing the subject and combining the divided images or combining multiple images of the same subject, a plurality of lenses are placed on one plate, unlike an embodiment of the present invention. It is also possible to consider using array lenses arranged in a matrix form.

That is, by stacking and arranging multiple array lenses in the optical axis direction, a lens assembly having a plurality of optical axes can be realized.

In this case, array lenses having a plurality of optical axes are placed on one lens barrel. However, when multiple array lenses are stacked on one lens barrel, there is a major problem in that each optical axis cannot be aligned individually.

However, in the lens assembly 100 according to an embodiment of the present invention, it is possible to individually align the optical axes of the plurality of lens modules by individually arranging the plurality of lens modules in the lens holder 190.

The lens holder 190 may be provided with an opening 191. For example, the opening 191 may be configured to penetrate the side surface of the lens holder 190 in a diagonal direction around the optical axis.

For example, a virtual line connecting the optical axis of the first lens module 110 and the optical axis of the fourth lens module 170, and a virtual line connecting the optical axis of the second lens module 130 and the optical axis of the third lens module 150. The lines may intersect each other and pass through the opening 191.

Accordingly, a portion of the side surfaces of the first to fourth lens modules 110 to 170 may be exposed to the outside through the opening 191.

Since a plurality of lens modules may be arranged in an n×n or n×m matrix structure, the lens assembly 100 may have the largest size in the diagonal direction.

Since the lens holder 190 has an opening 191 penetrating the side of the lens holder 190 in a diagonal direction about the optical axis, the size of the lens assembly 100 can be reduced.

7A to 7C show a perspective view of the first lens module 110. Hereinafter, for convenience of explanation, the first lens module 110 will be described. However, the second lens module 130 to the fourth lens module 170 may also have the same shape as the first lens module 110.

The first lens module 110 includes at least one lens and a first lens barrel 115.

The first lens barrel 115 may include a first barrel 111 and a second barrel 113. The first barrel 111 and the second barrel 113 may be used to refer to the upper and lower parts of one lens barrel, respectively. In another embodiment, the first barrel 111 and the second barrel 113 may be provided as separate structures and may be coupled to each other.

The first barrel 111 may have a cylindrical shape with an internal space, and the second barrel 113 may have a square box shape with an internal space. The upper surface of the first barrel 111 and the lower surface of the second barrel 113 are each provided with a passage hole through which light passes.

At least one lens (L1, hereinafter referred to as 'first lens') having a circular planar shape may be disposed inside the first barrel 111, and inside the second barrel 113 may be disposed a non-circular shape. At least one lens (L2, hereinafter referred to as 'second lens') having a planar shape may be disposed.

For example, referring to FIG. 7A, the second lens L2 is non-circular when viewed from the optical axis direction.

In a plane perpendicular to the optical axis, the length of the second lens L2 in the first axis direction perpendicular to the optical axis is longer than the length in the second axis direction perpendicular to both the optical axis and the first axis direction.

For example, the second lens L2 has a major axis (a) and a minor axis (b). The line segment connecting both sides of the second lens (L2) in the first axis direction while passing through the optical axis is the long axis (a), and the line segment connecting both sides of the second lens (L2) in the second axis direction while passing through the optical axis is the long axis (a). The line segment is short axis (b). The major axis (a) and minor axis (b) are perpendicular to each other, and the length of the major axis (a) is longer than the length of the minor axis (b).

The second lens L2 has four sides along the circumference of the second lens L2. When viewed from the optical axis direction, two of the four sides have a generally straight shape, a portion of each of the remaining two sides has an arc shape, and the remainder has a straight shape.

For example, the planar shape of the second lens L2 may be rectangular with rounded corners.

Generally, the image sensor 410 is rectangular, so not all light refracted by the circular lens is imaged on the image sensor 410.

In this embodiment, by having the second lens L2 have a non-circular planar shape, the lens and lens barrel can be miniaturized without affecting image formation, and thus the size of the lens module and camera module can be reduced. .
