In one embodiment, the processor (e.g., processor (120) of FIG. 1) can perform a focus adjustment operation and / or a focal length adjustment operation by linearly moving at least one of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) along the optical axis (O) with respect to the image sensor (I). In one embodiment, the processor (e.g., processor (120) of FIG. 1) can perform a shake correction operation by horizontally moving at least one of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) or the image sensor (I) parallel to a plane perpendicular to the optical axis (O). In one embodiment, the processor may cause the electronic device to receive or detect external light using the image sensor (I) while performing focus adjustment and / or image stabilization operations by executing at least a portion of instruction(s) stored in a memory (e.g., memory (130) of FIG. 1). For example, the memory may store instruction(s) that cause the electronic device to receive at least a portion of light focused on the image sensor (I) and acquire an image of an object (S) based on the received light, and such instruction(s) may be executed by the processor(s).

[0120] In the embodiments described below, although some of the reference numbers assigned to the lens surfaces in the drawings are not directly mentioned, those skilled in the art will be able to easily understand the configuration of each lens (L1, L2, L3, L4, L5, L6, L7, L8) or the lens surfaces based on the lens data presented through the [Tables] described below. In examining various embodiments below, for the sake of brevity of the drawings, the reference numbers for some of the object-side surface(s) and the sensor-side surface(s) of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) and / or the inflection point (IP) may be omitted. In the detailed description below, the 'inflection point (IP)' refers to a point where the radius of curvature changes and a portion of the object-side surface(s) and the sensor-side surface(s) does not intersect the optical axis (O), and may be indicated by a symbol '●' in the drawings, and the reference numbers may be omitted. Here, 'the radius of curvature changes' can be understood as the value of the radius of curvature changes from a negative value to a positive value or from a positive value to a negative value.

[0121] Reference numerals for lens surfaces omitted in the drawings may be applied to configurations of different embodiments, and can be easily understood through the [Tables] described below regarding lens data of each embodiment. In the detailed description of the embodiment(s) of the present disclosure, the term "concave" or "convex" with respect to the object-side surface or the sensor-side surface of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) may refer to the shape of the lens surface at a point intersecting the optical axis (O) or in a paraxial region intersecting the optical axis (O). The shape referred to as "concave" may refer to a shape in which the lens surface forms a curved surface in such a way that the lens thickness decreases as it approaches the optical axis (O) in the paraxial region. The shape referred to as "convex" may refer to a shape in which the lens surface forms a curved surface in such a way that the lens thickness increases as it approaches the optical axis (O) in the paraxial region.

[0122] In addition, in the detailed description below, values ​​for the radius (e.g., radius of curvature), effective focal length (f), OAL (overall length), TTL (total track length), air gap, thickness or image height of the image sensor (I) of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) of the present disclosure may all have units of mm unless otherwise specified. 'OAL' is the distance from the object-side surface of the first lens on the object side to the sensor-side surface of the first lens on the image sensor side, and is measured from the optical axis (O), and 'TTL' is the distance from the top of the barrel on which the lenses are arranged or fixed to the imaging plane (img) of the image sensor (I), and may be measured parallel to the optical axis (O). Additionally, the radius, effective focal length, OAL, air gap or thickness of the lenses (L1, L2, L3, L4, L5, L6, L7, L8) may be a distance measured relative to the optical axis (O), and / or the elevation of the image sensor (I) may be a distance measured along a direction substantially perpendicular to the optical axis (O) from a point where the optical axis (O) intersects.

[0123] According to one embodiment, among the lenses (L1, L2, L3, L4, L5, L6, L7, L8), the lens disposed first from the object (S) side, for example, the first lens (L1) disposed farthest from the image sensor (I), may have positive refractive power. In one embodiment, at least one of the object-side surface (S2) and the sensor-side surface (S3) of the first lens (L1) may be aspherical.

[0124] According to one embodiment, a second lens (L2) disposed second from the object (S) side, for example, disposed between the first lens (L1) and the image sensor (I), may have positive refractive power or negative refractive power. In one embodiment, the object-side surface (S4) of the second lens may have a convex shape. In one embodiment, at least one of the object-side surface (S4) or the sensor-side surface (S5) of the second lens may be aspherical. In one embodiment, the object-side surface (S4) of the second lens may be aspherical and convex. In one embodiment, the second lens (L2) may be a lens having a refractive index of approximately 1.6 or greater. In the illustrated embodiment, among the lenses (L1, L2, L3, L4, L5, L6, L7, and L8), the second lens (L2) may have the highest refractive index. As will be seen with reference to FIG. 10, FIG. 14, FIG. 18 and / or FIG. 22, among the lenses (L1, L2, L3, L4, L5, L6, L7, L8), any one of the second lens (L2), the fourth lens (L4) and / or the fifth lens (L5) may be the lens having the highest refractive index.

[0125] According to one embodiment, the third lens (L3) is positioned third from the object (S) side, for example, between the second lens (L2) and the image sensor (I), and may have positive or negative refractive power. In one embodiment, the sensor-side surface (S7) of the third lens may be concave. In one embodiment, at least one of the object-side surface (S6) or the sensor-side surface (S7) of the third lens may be aspherical.

[0126] According to one embodiment, the fourth lens (L4) is positioned fourth from the object (S) side, for example, between the third lens (L3) and the image sensor (I), and may have positive or negative refractive power. In one embodiment, the object-side surface (S8) of the fourth lens (L4) may serve as an aperture. In one embodiment, at least one of the object-side surface (S8) or the sensor-side surface (S9) of the fourth lens (L4) may be aspherical. In one embodiment, the fourth lens (L4) may be a lens having a refractive index of approximately 1.6 or greater.

[0127] According to one embodiment, the fifth lens (L5) disposed between the fourth lens (L4) and the image sensor (I) may have positive refractive power or negative refractive power. In one embodiment, at least one of the object-side surface (S10) or the sensor-side surface (S11) of the fifth lens (L5) may be aspherical. In one embodiment, the fifth lens (L5) may include an aspherical object-side surface (S10) and an aspherical sensor-side surface (S11). In one embodiment, the fifth lens (L5) may be a lens having a refractive index of approximately 1.6 or greater.

[0128] According to one embodiment, the sixth lens (L6) disposed between the fifth lens (L5) and the image sensor (I) may have positive refractive power or negative refractive power. In one embodiment, at least one of the object-side surface (S12) or the sensor-side surface (S13) of the sixth lens (L6) may be aspherical. In one embodiment, the sixth lens (L6) may include an aspherical object-side surface (S12) and an aspherical sensor-side surface (S13). In one embodiment, the sixth lens (L6) may be a lens having a refractive index of approximately 1.6 or greater.

[0129] According to one embodiment, the seventh lens (L7) positioned between the sixth lens (L6) and the image sensor (I) may have a defined refractive power. In one embodiment, at least one of the object-side surface (S14) or the sensor-side surface (S15) of the seventh lens (L7) may be aspherical.

[0130] According to one embodiment, the eighth lens (L8) is disposed between the seventh lens (L7) and the image sensor (I) and may have negative refractive power. In one embodiment, the eighth lens (L8) may be understood as a lens disposed closest to the image sensor (I) among the lenses (L1, L2, L3, L4, L5, L6, L7, L8), and at least one of the object-side surface (S14) or the sensor-side surface (S15) may be aspherical. In one embodiment, the eighth lens (L8) may include at least one inflection point on at least one of the object-side surface (S14) or the sensor-side surface (S15). In one embodiment, the eighth lens (L8) may include inflection point(s) provided on the object-side surface (S14) and inflection point(s) provided on the sensor-side surface (S15).

[0131] In one embodiment, the infrared cut filter (F) may be disposed between the eighth lens (L8) and the image sensor (I). As previously mentioned, the infrared cut filter (F) may block light in a wavelength band that is not detectable by the user's naked eye but is detected by a photosensitive material or the image sensor (I). In one embodiment, when the camera module (400) functions as a camera that detects light in an infrared wavelength band (e.g., a depth camera), the infrared cut filter (F) may be replaced with a bandpass filter, and / or may be implemented as a coating material disposed on a lens surface of any one of the lenses (L1, L2, L3, L4, L5, L6, L7, L8).

[0132] According to one embodiment, the camera module (400) and / or its lens assembly (LA) can be miniaturized while providing optical performance suitable for a large-sized and / or high-pixel image sensor (I) by satisfying at least one of the conditions presented through the following [mathematical equations].

[0133]

[0134] According to one embodiment, when the camera module (400) and / or its lens assembly (LA) satisfy the condition of [Mathematical Formula 1] such that the refractive index 'N4' of the fourth lens (L4) is approximately 1.6 or higher, the camera module (400) and / or its lens assembly (LA) can be miniaturized and provide good image quality performance. For example, when the refractive index of the fourth lens (L4) becomes less than approximately 1.6, it may be difficult to compensate for field curvature in the miniaturized lens assembly (LA). In one embodiment, in order to secure good aberration correction performance when the refractive index of the fourth lens (L4) becomes less than approximately 1.6, the lens assembly (LA) can be enlarged.

[0135]

[0136] According to one embodiment, [Mathematical Formula 2] presents conditions regarding the refractive index 'N1' of the first lens (L1) and the refractive index 'N7' of the seventh lens (L7). When these refractive index conditions are not satisfied, the spherical aberration or coma aberration of the lens assembly (LA) may increase. For example, when the refractive index 'N1' of the first lens (L1) is lower than the refractive index 'N7' of the seventh lens (L7), aberration correction becomes easier, and the implementation of a bright optical system or miniaturization of the lens assembly (LA) may become easier.

[0137] According to one embodiment, the camera module (400) and / or the lens assembly (LA) may satisfy the conditions of [Mathematical Formula 3] regarding the focal length 'EFL', the angle of view 'FOV', and / or the lens total length 'OTTL'. The lens total length may be, for example, a distance from the object-side surface (S2) of the first lens (L1) to the image sensor (I) (e.g., the imaging plane (img)), which may be a distance measured from the optical axis (O).

[0138]

[0139] In one embodiment, the unit of the value calculated by [Mathematical Formula 3] may be 'degree'. When the condition of [Mathematical Formula 3] is satisfied, the camera module (400) and / or the lens assembly (LA) may be miniaturized, while the camera module (400) and / or the lens assembly (LA) may be easily manufactured. For example, when the value calculated by [Mathematical Formula 3] is less than 70, it is easy to secure optical performance, but when combined with a high-pixel and / or large-screen image sensor (I), the lens total length 'OTTL' may increase, making miniaturization difficult. In one embodiment, when the value calculated by [Mathematical Formula 3] is greater than 85, the lens total length 'OTTL' may decrease, making miniaturization easy, but the lenses (L1, L2, L3, L4, L5, L6, L7, L8) may become small, making assembly difficult. For example, as the lens total length 'OTTL' becomes smaller, handling or assembling of lenses (L1, L2, L3, L4, L5, L6, L7, L8) may become difficult, and the defect rate due to assembly deviation may increase, making mass production difficult. In one embodiment, in the camera module (400) and / or the lens assembly (LA), the calculated value by [Mathematical Formula 3] may be in the range of approximately 75 or more and approximately 80 or less.

[0140] According to one embodiment, the camera module (400) and / or the lens assembly (LA) may satisfy the condition of the following [Mathematical Formula 4] regarding the radius of curvature of the eighth lens (L8). Here, the 'radius of curvature' may refer to, for example, the radius of curvature 'R8_1' of the object-side surface (S16) of the eighth lens (L8) and / or the radius of curvature 'R8_2' of the sensor-side surface (S17) of the eighth lens, and may be the radius of curvature at the point where the optical axes (O) intersect.

[0141]

[0142] In one embodiment, when the calculated value by [Mathematical Formula 4] is less than -90, there may be difficulties in manufacturing or assembling the camera module (400) and / or the lens assembly (LA). For example, there may be difficulties in manufacturing the eighth lens (L8) in a designed shape or assembling it in a designated position. In one embodiment, when the calculated value by [Mathematical Formula 4] is greater than -20, the distortion of the camera module (400) and / or the lens assembly (LA) may increase, so that the image of the surrounding image may be distorted differently from the subject, and an additional lens may be required to compensate for this. For example, when the condition of [Mathematical Formula 4] is satisfied, the manufacturing or miniaturization of the camera module (400) and / or the lens assembly (LA) may be facilitated. In one embodiment, the calculated value by [Mathematical Formula 4] of the camera module (400) and / or the lens assembly (LA) may satisfy a range of approximately -70 or more and approximately -30 or less.

[0143] In one embodiment, the camera module (400) and / or its lens assembly (LA) may have a focal length of approximately 6.28 mm, an F-number of approximately 1.796, and a lens length of approximately 6.844 mm. In one embodiment, the camera module (400) and / or its lens assembly (LA) may satisfy at least some of the above-described condition(s), and may be manufactured with the specifications exemplified in the following [Table 1].

[0145] [Table 2], [Table 3], [Table 4], and [Table 5] below list the aspherical coefficients of lenses (L1, L2, L3, L4, L5, L6, L7, L8), and the definition of aspherical is as follows [Mathematical Formula 5].

[0146]

[0147] In [Mathematical Formula 5], “x” is the distance in the direction of the optical axis (O) from the point where the optical axis (O) passes on the lens surface, “y” is the distance from the optical axis (O) in the direction perpendicular to the optical axis (O), “R” represents the radius of curvature at the vertex of the lens, “k” represents the conic constant, and “Ai” represents the aspherical coefficient, which can be written as “A”, “B”, “C”, “D”, “E”, “F”, “G”, “H”, “J”, “K”, “L”, “M”, “N”, and “O” in the [Table] described below.
