Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/KR2022/013451 designating the United States, filed on Sep. 7, 2022, in the Korean Intellectual Property Receiving Office and claiming priority to Korean Patent Application No. 10-2021-0155350, filed on Nov. 12, 2021, in the Korean Intellectual Property Office, the disclosures of all of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     Technical Field 
     Certain embodiments of the disclosure relate to an electronic device, e.g., a lens assembly and an electronic device including the same. 
     Description of Related Art 
     Lens assemblies, for example, cameras capable of capturing images or videos have been widely used, and digital cameras or video cameras with solid image sensors such as charge coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) have recently become commonplace. Solid image sensor (CCD or CMOS)-adopted lens assemblies may easily save, copy, or move, between electronic devices, images as compared with film-type lens assemblies and have thus been replacing film-type lens assemblies. 
     A plurality of lens assemblies, e.g., two or more selected from a macro camera, a telephoto camera, and/or a wide-angle camera, can be built in one electronic device to enhance the quality of captured images and give various visual effects to captured images. For example, multiple cameras can be used to obtain images of an object. The multiple cameras can have different optical properties. The images from the multiple cameras can be synthesized to obtain a high-quality captured image. 
     The electronic device, made lighter and/or more compact for everyday carrying and use, may encounter difficulty in enhancing the performance of the camera or lens assembly. For example, although image quality is enhanced by combining a plurality of lens assemblies, it is still hard to pack the compact and/or lightweight electronic device with the telephoto or zoom function due to its small space. 
     Certain embodiments of the disclosure aim to address the foregoing issues and/or drawbacks and provide advantages described below, providing a lens assembly, which has a reduced size while implementing the zoom function, and/or an electronic device including the same. 
     Other aspects according to certain embodiments will be suggested through in the following detailed description and would be partially apparent from the description or appreciated through the suggested embodiments. 
     The above-described information may be provided as background for the purpose of helping understanding of the disclosure. No claim or determination is made as to whether any of the foregoing is applicable as background art in relation to the disclosure. 
     SUMMARY 
     According to certain embodiments, a lens assembly comprises, an image sensor; a first lens group; a second lens group; and a third lens group, wherein the first lens group has a negative refractive power, is disposed along an optical axis direction from the image sensor, and comprises at least two lenses; wherein the second lens group has a positive refractive power and is configured to move along the optical axis direction between the first lens group and the image sensor, the second lens group comprising at least two lenses; wherein the third lens group has a negative refractive power and is configured to move back and forth along the optical axis direction between the second lens group and the image sensor, the third lens group comprising at least one lens, wherein the lens assembly is configured to perform zooming, and wherein during zooming, as at least one of the second lens group and the third lens group moves toward an object side, a focal length of the lens assembly increases, and wherein the lens assembly meets conditional equation 1 and conditional equation 2, wherein

     It should be noted that in the following detailed description, reference may be made to the electronic devices  101 ,  200 , and  300  of the foregoing embodiments, and components, which may easily be understood through the foregoing embodiments, are assigned the same reference numerals or omitted and a description thereof may be omitted. 
       FIG.  5    is a rear plan view illustrating a rear surface of an electronic device  400  (e.g., the electronic devices  101 ,  200 , and  300  of  FIGS.  1  to  4   ) according to certain embodiments of the disclosure.  FIG.  6    is a cross-sectional view illustrating a portion of the electronic device  400 , taken along line A-A′ of  FIG.  5   . 
     The electronic device  400  includes camera module  405  that are exposed through transparent areas  387  in camera window  385 . Moreover, one of the camera modules  405  can be a folded camera as shown in  FIG.  6   . In the folded camera, light L 1  is incident orthogonally to the surface of the electronic device. A reflective member  455  reflects the light L 1  in a direction along an optical axis O that is substantially parallel and between the front and rear surface of the electronic device through lenses  453   a  . . .  453   f . It is noted that the optical axis is not in the direction of the thickness of the electronic device, thereby allowing more room for the lenses. 
     Referring to  FIGS.  5  and  6   , the electronic device  400  may include a camera window  385  disposed on one surface (e.g., the second surface  210 B of  FIG.  3   ). In some embodiments, the camera window  385  may be a portion of the rear plate  380 . In an embodiment, the camera window  385  may be coupled to the rear plate  380  through a ring  389 . When it is viewed from the outside, the ring  389  may be exposed in a form surrounding the camera window  385 . The camera window  385  may include a plurality of transparent areas  387 . The electronic device  400  may receive external light or emit light to the outside through at least one of the transparent areas. For example, the electronic device  400  may include at least one camera module  405  (e.g., the camera modules  180 ,  205 ,  212 , and  213  of  FIGS.  1  to  3   ) disposed to correspond to at least some of the transparent areas  387  and at least one light source (e.g., an infrared light source) disposed to correspond to others of the transparent areas  387 . For example, the camera module or the light source may receive external light or emit light to the outside of the electronic device  400  through any one of the transparent areas  387 . 
     The electronic device  400  may include at least one of a camera module  405  or a light receiving element (e.g., a lens assembly such as a wide-angle camera, an ultra-wide-angle camera, a macro camera and a telephoto camera, or an infrared photodiode), and may include a flash (e.g., the flash  213  of  FIG.  3   ) or an infrared laser diode as a light source or light emitting element. In an embodiment, the electronic device  400  may emit an infrared laser to the subject to detect the distance or depth. In another embodiment, the electronic device  400  may obtain an image of the subject by the lens assembly, e.g., by any one or a combination of two or more of the camera modules  405  and, as needed, provide illumination toward the subject by means of a flash. 
     The camera modules can include a wide-angle camera, an ultra-wide-angle camera, or a macro camera. The macro camera may have a smaller length in the optical axis (O) direction of the lens(es) as compared to the telephoto camera (e.g., the camera module  405 ). For example, the telephoto camera (e.g., the camera module  405 ) having a relatively large focal length adjustment range may secure a sufficient length or space in the optical axis O direction and thus a distance and area where the lens(es)  453  (s) may move. In an embodiment, in the wide-angle camera, the ultra-wide-angle camera, or the macro camera, although the lens(es) are arranged along the thickness (e.g., the thickness measured in the Z-axis direction of  FIG.  4  or  6   ) of the electronic device  400 , the substantial influence on the thickness of the electronic device  400  may be small. For example, the wide-angle camera, the ultra-wide-angle camera, or the macro camera may be disposed in the electronic device  400  such that light is incident from the outside to the electronic device  400  and the optical axis direction of the lens(es) are substantially the same. In another embodiment, as compared with the wide-angle camera, the ultra-wide-angle camera, or the macro camera, the camera module  405  (e.g., a telephoto camera) has a small angle of view but may be useful for capturing a subject at a greater distance and may include more lens(es)  453  or a longer moving distance of the lens(es)  453  in focal length adjustment. For example, when the lens(es)  453  of the camera module  405  are arranged in the thickness direction (e.g., the Z-axis direction) of the electronic device  400 , the thickness of the electronic device  400  may increase or a significant portion of the camera module  405  may protrude to the outside of the electronic device  400 . 
     A folded camera (e.g., the camera module  405 ) further may include a reflective member  455 , such as a prism, so that the direction (e.g., the optical axis O direction of  FIG.  6   ) in which the lens(es)  453  are arranged, may be configured to cross the direction in which external light is incident (e.g., the incident direction L 1  of  FIG.  6   ). For example, the reflective member  455  may refract or reflect the light incident from the outside to change the propagation direction of the light and guide the light to the image sensor  451  or in the direction in which the lens(es)  453  are arranged. 
     The reflective member  455  may include an incident surface I, an exit surface, and a reflective surface. The incident surface I faces the external space. The exit surface E faces the lens  453 . The reflective surface R is inclined with respect to the incident surface I (or exit surface E). For example, external light may be incident through the incident surface I and be reflected by the reflective surface R, and the reflected light may pass through the exit surface E to the lens  453  or the image sensor  451 . Depending on the shape or size, the electronic device  400  may not include the reflective member  455 , and when it does not include the reflective member  455 , the incident direction L 1  may be substantially parallel to or coincident with the optical axis O direction. The incident direction L 1  may be substantially parallel to the thickness direction (e.g., the 
     Z-axis direction) of the electronic device  400 . The arrangement direction of the lens(es)  453  may be a direction in which the light refracted or reflected by the reflective member  455  travels and crosses the incident direction L 1 . In some embodiments, the arrangement direction or the optical axis O direction of the lens(es)  453  may be substantially perpendicular to the incident direction L 1 , and be parallel to the width direction (e.g., the X-axis direction of  FIG.  4   ) or the length direction (e.g., the Y-axis direction of  FIG.  4   ) of the electronic device  400  or the housing (e.g., the housing  210  of  FIG.  2   ). 
     The lens assembly or camera module  405  illustrated in  FIG.  6    is an example of a folded camera or a telephoto camera and may be disposed so that the lens(es)  453  may move back and forth in the width direction (e.g., a direction parallel to the X axis, or the optical axis O direction) of the electronic device  400 . The camera module  405  may include a reflective member  455  that receives and refracts or reflects external light, a lens(es)  453  that focuses the light refracted or reflected by the reflective member  455 , and/or an image sensor  451  aligned on the optical axis O of lens(es)  453 . For example, the image sensor  451  may receive external light through the reflective member  455  and the lens(es)  453 . In some embodiments, external light may be incident on the reflective member  455  along the incident direction L 1 , and be reflected or refracted by the reflective member  455  and be guided through the lens(es)  453  to the image sensor  451  along the optical axis O direction. 
     The reflective member  455  may include, e.g., a prism, and may reflect or refract the light, incident in the incident direction L 1 , in a direction perpendicular to the incident direction L 1  (e.g., the optical axis O direction). Although the configuration in which the incident direction L 1  and the optical axis O direction are perpendicular to each other is shown in the present embodiment, certain embodiments of the disclosure are not limited thereto. Depending on the structure of the electronic device  400  or the housing (e.g., the housing  210  of  FIG.  2   ), the angle between the incident direction L 1  and the optical axis O direction crossing effective area may vary. 
     The camera module  405  may include a plurality of lenses  453  sequentially arranged along the optical axis O direction from the side of the object (e.g., the object obj of  FIG.  7   ). In the following detailed description, the plurality of lenses  453  may be distinguished by adding lowercase letters to the reference numbers as necessary. In an embodiment, the incident direction L 1  may be parallel to the thickness direction (e.g., the Z-axis direction) of the electronic device  400 . The optical axis (O) direction may be parallel to the width direction (e.g., the X-axis direction) or the length direction (e.g., the Y-axis direction) of the electronic device. 
     In  FIG.  6   , the camera module  405  may include six lenses  453 , and at least one lens  453  sequentially selected from the object side may form a first lens group G 1 , a second lens group G 2 , and/or a third lens group G 3 . In certain embodiments, the number of lenses  453  or the number of lenses  453  included in each lens group G 1 , G 2 , and G 3  may be different from that in the illustrated embodiment, which will be further discussed with reference to the embodiments of  FIGS.  7  to  26 C . In the illustrated embodiment, the first lens group G 1  may include a first lens  453   a  and a second lens  453   b,  the second lens group G 2  may include a third lens  453   c  and a fourth lens  453   d,  and/or the third lens group G 3  may include a fifth lens  453   e  and a sixth lens  453   f.    
     The lens(es)  453  may be formed of or comprises a synthetic resin so as to have a high design freedom in size or shape. The lens(es)  453  formed of the synthetic resin may have deviations in resolution depending on changes in temperature or humidity. The deviation in resolution in the lens assembly or camera module  405  having a large focal length may be larger than that of a standard camera or a wide-angle camera. According to certain embodiments, when the camera module  405  implements the telephoto function, at least one of the lenses  453  of the first lens group G 1  and/or at least one of the lenses of the second lens group G 2  may be formed of a glass material and prevent the deviation in resolution that may occur with resin. 
     At least one of the lens groups G 1 , G 2 , and G 3  may move forward and backward along the optical axis O direction between the image sensor  451  and the reflective member  455 . For example, at least one of the lens groups G 1 , G 2 , and G 3  may perform a zoom function or focusing operation for adjusting the focal length. In an embodiment, when the first lens  453   a  or the first lens group G 1  disposed first from the object side is visually exposed to the external space, the first lens group G 1  may remain in a static state. The electronic device  400  or the processor  120  of  FIG.  1    may performs focal length adjustment or focus adjustment using the second lens group G 2  and/or the third lens group G 3 . For example, the electronic device  400  or the processor  120  of  FIG.  1    may adjust the focal length by moving the second lens group G 2  forward and backward in the optical axis O direction or perform focus adjustment by moving the third lens group G 3  forward and backward in the optical axis O direction. 
     The first lens group G 1  among the lens groups G 1 , G 2 , and G 3  may be disposed first from the object side, and may include at least two lenses  453   a  and  453   b  to have a negative refractive power (negative power). When the first lens  453   a  has positive refractive power, the size of the total luminous flux is reduced. This makes it easier to downsize or miniaturize the lens assembly or camera module  405 . The second lens  453   b  of the first lens group G 1  may be disposed between the first lens  453   a  and the image sensor  451 , and may also have negative refractive power. The first lens group G 1  may further include at least one lens having positive or negative refractive power. 
     The second lens group G 2  may include at least two lenses  453   c  and  453   d.  The second lens group G 2  can have positive power and be configured to move forward and backward along the optical axis O direction between the first lens group G 1  and the image sensor  451 . For example, the second lens group G 2  may adjust the focal length or perform focus adjustment by moving forward and backward along the optical axis O direction. The second lens group G 2  may include at least one lens having a positive refractive power and at least one lens having a negative refractive power. In certain embodiments, when the second lens group G 2  moves toward the object with respect to the first lens group G 1  or the image sensor  451 , the focal length of the lens assembly or camera module  405  may be increased. In another embodiment, when the second lens group G 2  moves toward the image sensor  451  with respect to the first lens group G 1  or the image sensor  451 , the focal length of the lens assembly or camera module  405  may be reduced, and the field of view (FOV) may be increased. 
     The third lens group G 3  among the lens groups G 1 , G 2 , and G 3  may include two lenses  453   e  and  453   f  and have negative refractive power and be arranged to move forward and backward along the optical axis O direction between the second lens group G 2  and the image sensor  451 . For example, the third lens group G 3  may perform focus adjustment or adjust the focal length by moving forward and backward along the optical axis O direction. The third lens group G 3  may include one lens having a positive refractive power and one lens having a negative refractive power. 
     The lens assembly or camera module  405  may further include an infrared cut filter  457  disposed between the third lens group G 3  and the image sensor  451 . Infrared rays are practically indistinguishable with the naked eye, but may be detected by a photosensitive film or image sensor  451 . The infrared cut filter  457  blocks the infrared rays incident on the image sensor  451 , thereby reducing or preventing degradation of the quality of the captured image. 
     The electronic device  400  may include a first camera supporting member  381  or a second camera supporting member  383 . The first camera supporting member  381  or the second camera supporting member  383  may place or fix at least one of the camera module  405  and/or another camera module adjacent to the camera module  405  (e.g., a wide-angle camera, an ultra-wide-angle camera, or a macro camera) to the inside of the rear plate  380  or the camera window  385 . In some embodiments, the first camera supporting member  381  or the second camera supporting member  383  may be substantially a portion of a first supporting member (e.g., the second supporting member  360  of  FIG.  4   ) or a second supporting member (e.g., the first supporting member  311  of  FIG.  4   ). 
     Although reference numerals and detailed descriptions of the drawings are omitted, the camera module  405  or the electronic device  400  may further include a barrel structure for disposing the lens(es)  453  in a designated position and/or a driving device for moving forward and backward the lens(es) or at least one of the lens groups G 1 , G 2 , and G 3  for focus adjustment. In some embodiments, the camera module  405  or the electronic device  400  may further include another driving device for moving the image sensor  451  on a plane substantially perpendicular to the optical axis O direction, and may perform an image stabilization operation by moving the image sensor  451 . In another embodiment, the image stabilization operation may be implemented by rotating or tilting the reflective member  455  (e.g., a prism). In the image stabilization operation, the reflective member  455  may be rotated or tilted in an angular range of about 1.5 degrees. 
     When combined with another camera module (e.g., a wide-angle camera, an ultra-wide-angle camera, or a macro camera), the camera module  405  may function as a tracking or scan camera that tracks the subject within the area of the image captured by the wide-angle camera, ultra-wide-angle camera, or macro camera or scans a partial area of the image. In tracking the subject or scanning a portion of the image area, the angular range in which the reflective member  455  is rotated or tilted may be larger than in the image stabilization operation. 
     It should be noted that in the drawings, in adding reference numerals to the lens(es) and/or the lens surfaces of the infrared cut filter, the reference numerals for the object-side surfaces are shown in the views (e.g.,  FIG.  7 ,  11 ,  15 ,  19   , or  23 ) showing the wide-angle end, and the reference numerals for the image sensor-side surfaces are shown in the views (e.g.,  FIG.  8 ,  12 ,  16 ,  20   , or  24 ) exemplifying the telephoto end. ‘Wide-angle end’ may mean a position or state in which, in the moving range of the second lens group G 2  or third lens group G 3 , the focal length of the lens assembly  500  is the minimum, and the angle of view is the maximum. ‘Telephoto end’ may mean a position or state in which, in the moving range of the second lens group G 2  or third lens group G 3 , the focal length of the lens assembly  500  is the maximum, and the angle of view is the minimum. There may be a lens surface that is shown in the tables regarding lens data, but omitted from the drawings. For example, ‘S 5 ’ in Table 1 may be omitted from  FIG.  7    or  FIG.  8   . The lens surface shown in the tables but omitted from the drawings may mean a structure, such as a film for controlling aberration or blocking stray light. In another embodiment, a structure (e.g., a spacer) for fixing two adjacent lenses may function as a structure for controlling aberration or blocking stray light, and even in this case, it may be omitted from the drawings but may be described as a lens surface in the tables. 
     In certain embodiments, the first group G 1  can include lenses  511 ,  512 , the second group G 2 , can include lenses  521 ,  522 , and  523 , and the third lens group G 3  can include lenses  531 , and  532 . The second and third lens groups G 2  and G 3  can move along the optical axis O. 
       FIG.  7    is a view illustrating a configuration of a lens assembly  500  (e.g., the camera module  405  of  FIG.  6   ) according to certain embodiments of the disclosure, in which a lens (group) arrangement at the wide-angle end is shown.  FIG.  8    is a view illustrating the configuration of the lens assembly  500  of  FIG.  7   , in which an arrangement of lenses (group) at a telephoto end is shown.  FIGS.  9 A to  9 C  are graphs illustrating spherical aberration, astigmatism, and distortion rate of the lens assembly  500  of  FIG.  7   .  FIGS.  10 A to  10 C  are graphs illustrating spherical aberration, astigmatism, and distortion rate of the lens assembly  500  of  FIG.  8   . 
     Referring to  FIGS.  7  to  10 C , a lens assembly  500  (e.g., the camera module  405  of  FIG.  6   ) may include an image sensor  451 , three lens groups G 1 , G 2 , and G 3  sequentially arranged from an object obj to the image sensor  451  along an optical axis O direction, and/or an infrared cut filter  457  disposed between the image sensor  451  and the lens groups G 1 , G 2 , and G 3 . The first lens group G 1  among the three lens groups G 1 , G 2 , and G 3  may have a negative refractive power, and be disposed first from the object obj side, in a fixed state with respect to the image sensor  451 . Among the three lens groups G 1 , G 2 , and G 3 , the second lens group G 2  may have positive refractive power and be disposed between the first lens group G 1  and the image sensor, and the third lens group G 3  may have negative refractive power and be disposed between the second lens group G 2  and the image sensor  451 . 
     The first lens group G 1  may include at least two lenses (e.g., two lenses)  511  and  512 . At least one of the lenses  511  and  512  of the first lens group G 1  may be formed of a glass material. In an embodiment, the lens assembly  500  and/or the first lens group G 1  may meet a condition according to Equation 1 below. 
       −1.7 ≤fG 11 /fG 1≤−0.6   [conditional equation 1]
 
     Here, ‘fG11’ may be the focal length of the first lens  511  on the object side among the lenses of the first lens group G 1 , and ‘fG1’ may be the focal length of the first lens group G 1 . For example, the first lens group G 1  may have a negative refractive power while the first lens  511  may have a positive refractive power. Over the upper limit of the condition presented through Equation 1, the refractive power of the first lens on the object side in the first lens group G 1  may be increased, so that although a bright lens assembly  500  may be implemented, it may be hard to correct the spherical aberration. In another embodiment, below the lower limit of the condition presented through Equation 1, the effective diameter of the diaphragm may be increased to implement the bright lens assembly  500 , so that it may be difficult to reduce the size of the lens assembly  500 . 
     The lens assembly  500  and/or the first lens group may further meet a condition according to Equation 2 below. 
       −3.2 ≤βG 3 t/βG 2 t≤− 2.5   [conditional equation 2]
 
     Here, ‘fw’ may be the focal length of the lens assembly  500  at the wide-angle end. When the lens assembly  500  and/or the first lens group G 1  meet the condition of Equation 2, the refractive power of the first lens group G 1  may be controlled and the lens assembly  500  may be downsized. According to an embodiment, over the upper limit of the condition presented through Equation 2, the focal length of the first lens group G 1  may be increased, so that the effective diameter of the lens assembly  500  may be increased. In some embodiments, if the focal length of the first lens group G 1  is increased, the distance between the first lens on the image sensor side of the third lens group G 3  and the imaging plane img at the wide-angle end may decrease. For example, over the upper limit of the condition presented through Equation 2, the incident angle CRA of the outermost ray incident on the imaging plane img at the wide-angle end may increase, and the deviation in the incident angle of the outermost ray at the telephoto end may increase, and it may be hard to control coma aberration. In another embodiment, below the lower limit of the condition presented through Equation 2, the focal length of the first lens group G 1  is reduced, so that it may be difficult to correct astigmatism and image field curvature at the wide-angle end. 
     The second lens group G 2  may include at least two lenses (e.g., three lenses)  521 ,  522 , and  523 . At least one of the lenses  521 ,  522 , and  523  of the second lens group G 2  may be formed of a glass material. In an embodiment, the lens assembly  500  and/or the second lens group G 2  may meet a condition according to Equation 3 below. 
       −1.4 ≤fG 2 n/fG 2≤−0.5   [Equation  3 ]
 
     Here, ‘fG2n’ may be the focal length of a lens having a negative refractive power among the lenses of the second lens group G 2 , and ‘fG2’ may be the focal length of the second lens group G 2 . When the second lens group G 2  meets the condition of Equation 3, the aberration of the lens assembly  500  may be easily corrected. According to an embodiment, over the upper limit of the condition presented through Equation 3, the refractive power of the first lens on the object side in the second lens group G 2  may increase, so that it may be difficult to correct astigmatism, and below the lower limit of the condition presented through Equation 3, the refractive power of the first lens on the object side in the second lens group G 2  may decrease, so that the sensitivity to the eccentricity error of the lens may be greatly increased. 
     The third lens group G 3  may include two lenses  531  and  532 , e.g., one having positive refractive power and the other having negative refractive power and, together with the second lens group G 2 , may meet the condition according to Equation 4 below, regarding the imaging magnification. 
       −32 &gt;βG 3 t/βG 2 t≤− 2   [Equation 4]
 
     Here, ‘βG3t’ may be the imaging magnification of the third lens group G 3  at the telephoto end, and ‘βG2t’ may be the imaging magnification of the second lens group G 2  at the telephoto end. When the condition of Equation 4 is met, in the lens assembly  500 , even when the distance that the second lens group G 2  or the third lens group G 3  moves along the optical axis O direction decreases, it may be easy to compensate for the amount of focus shift of the obtained image. For example, when the condition of Equation 4 is met, the lens assembly  500  may be easy to downsize while implementing a continuous zoom function. 
     The lens assembly  500  meeting the above-described conditions may have the focal length adjustable within a range of about 11.5 to 27.5 mm, the f-number adjustable in the range of about 2.8 to 5.0, and the angle of view adjustable in the range of about 28.2 to 11.6 degree(s) according to the forward and backward movement of the second lens group G 2  and/or the third lens group G 3  between the wide-angle end and the telephoto end. 
     Table 1 and Table 2 below show the lens data of the lens assembly  500  illustrated in  FIG.  7    or  FIG.  8   . ‘S 1 -S 17 ’ generally denote the lenses  511 ,  512 ,  521 ,  522 ,  523 ,  531 , and  532  and/or the lens surface of the infrared cut filter  457 . Particularly, ‘S 5 ’ may denote an area, position, or plane where a structure for controlling aberration or blocking stray light is disposed, and ‘img’ may denote the imaging plane of the image sensor  451 . In an embodiment, the structure for controlling aberration or blocking stray light (e.g., the surface or structure indicated by ‘S 5 ’ in 
     Table 1) may be implemented in the form of a film, or may be a structure for fixing the lens(es)  511 ,  512 ,  521 ,  522 ,  523 ,  531 , and  532  and may affect the size of the aperture while providing the function for adjusting the amount of ray bundles per field. In some embodiments, the ‘radius of curvature’ in Table 1 may be the radius of curvature of the lens surface measured at the point where the optical axis O passes, and the ‘thickness or air gap’ may be the thickness of the lens  511 ,  512 ,  521 ,  522 ,  523 ,  531 , and  532  or the gap between two adjacent lenses  511 ,  512 ,  521 ,  522 ,  523 ,  531 , and  532  measured at the point where the optical axis O passes.
