Description

Camera module and electronic device including the same

[0001] Embodiments of the present disclosure relate to electronic devices, for example, to camera modules and / or electronic devices including the same.

[0002] Optical devices, such as cameras capable of capturing images or videos, have been widely used for a long time. Recently, digital cameras and video cameras equipped with solid-state image sensors, such as charge-coupled devices (CCDs) or complementary metal-oxide semiconductors (CMOSs), have become widespread. Optical devices employing solid-state image sensors (CCDs or CMOSs) are gradually replacing film-based optical devices because they facilitate image storage, reproduction, and transfer compared to film-based optical devices.

[0003] Recently, multiple optical devices, such as a macro camera, a telephoto camera, and / or a wide-angle camera, are being mounted on a single electronic device to improve the quality of captured images and also to provide various visual effects to the captured images. For example, multiple cameras with different optical characteristics can acquire subject images and synthesize them to obtain a high-quality captured image. As multiple optical devices (e.g., cameras) are mounted to acquire high-quality captured images, electronic devices such as mobile communication terminals and smart phones are gradually replacing electronic devices specialized in capturing functions, such as digital compact cameras, and it is expected that in the future, they will be able to replace high-performance cameras such as digital single-lens reflex cameras (DSLR).

Referring to FIG. 2, the camera module (280) may include a lens assembly (210), a flash (220), an image sensor (230), an image stabilizer (240), a memory (250) (e.g., a buffer memory), or an image signal processor (260). In one embodiment, the lens assembly (210) may include an image sensor (230). The lens assembly (210) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (280) may include a plurality of lens assemblies (210). In this case, the camera module (280) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, F-number, or optical zoom), or at least one lens assembly may have one or more lens properties that are different from the lens properties of the other lens assemblies. The lens assembly (210) may include, for example, a wide-angle lens or a telephoto lens.

[0095] The flash (220) can emit light used to enhance light emitted or reflected from a subject. In one embodiment, the flash (220) can include one or more light-emitting diodes (e.g., red-green-blue (RGB) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. The image sensor (230) can acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (210) into an electrical signal. In one embodiment, the image sensor (230) can include one image sensor selected from among image sensors having different properties, such as, for example, an RGB sensor, a black and white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same property, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0096] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operating characteristics of the image sensor (230) (e.g., adjusting the read-out timing, etc.) in response to the movement of the camera module (280) or the electronic device (201) including the same. This allows compensating for at least some of the negative effects of the movement on the captured image. In one embodiment, the image stabilizer (240) can detect such movement of the camera module (280) or the electronic device (e.g., the electronic device (101) of FIG. 1) by using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module (280). In one embodiment, the image stabilizer (240) can be implemented as, for example, an optical image stabilizer. The memory (250) can temporarily store at least a portion of the image acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to the shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160) of FIG. 1. Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) can be configured as at least a portion of a memory (e.g., the memory (130) of FIG. 1) or as a separate memory that operates independently therefrom.

[0097] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor (260) may perform control (e.g., exposure time control, read-out timing control, etc.) on at least one of the components included in the camera module (280) (e.g., image sensor (230)). An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (280) (e.g., memory (130) of FIG. 1, display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) may include a processor (e.g., 1) may be configured as at least a part of the processor (120) or may be configured as a separate processor that operates independently of the processor (120). When the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).

[0098] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a plurality of camera modules (280), each having different properties or functions. In this case, for example, at least one of the plurality of camera modules (280) may be a wide-angle camera, and at least another may be a telephoto camera. Similarly, at least one of the plurality of camera modules (280) may be a front camera, and at least another may be a rear camera.

In one embodiment, the lens assembly (LA) may include at least five lenses (L1, L2, L3, L4, L5) aligned along an optical axis (O). In one embodiment, the camera module (400) and / or the lens assembly (LA) may include a barrel (B). The barrel (B) may be, for example, a structure for arranging or aligning lenses (L1, L2, L3, L4, L5). Although not given a reference number, at least one spacer may be arranged to align the positions of the lenses (L1, L2, L3, L4, L5) within the barrel (B) and prevent two adjacent lenses (L1, L2, L3, L4, L5) from making direct contact.

The drive structure may, for example, reciprocate at least one of the lenses (L1, L2, L3, L4, L5) along the optical axis (O) or horizontally move in a plane perpendicular to the optical axis (O). In one embodiment, the drive structure may be provided outside the barrel (B). For example, the entire barrel (B) or lens assembly (LA) may reciprocate along the optical axis (O) or horizontally move in a plane perpendicular to the optical axis (O).

[0123] According to one embodiment, the at least five lenses (L1, L2, L3, L4, L5) may include a first lens (L1) positioned furthest from the image sensor (I), a second lens (L2) positioned between the first lens (L1) and the image sensor (I), a third lens (L3) positioned between the second lens (L2) and the image sensor (I), a fourth lens (L4) positioned between the third lens (L3) and the image sensor (I), and / or a fifth lens (L5) positioned between the fourth lens (L4) and the image sensor (I). In one embodiment, the image sensor (I) may detect light focused or guided by the lens assembly (LA) (e.g., the at least five lenses (L1, L2, L3, L4, L5)) using an imaging plane (img). For example, the imaging plane (img) may be understood as an active area of ​​the image sensor (I).

[0124] In the illustrated embodiment, the phrase “arranged sequentially from the object (e.g., the object (S) of FIG. 6) side toward the image sensor (I)” or “aligned along the optical axis (O)” may refer to the lenses (L1, L2, L3, L4, L5) being arranged sequentially from the object (S) side toward the image sensor (I). In the embodiment described below, the ordinal numbers “first,” “second,” “third,” “fourth,” and “fifth” assigned to the lenses (L1, L2, L3, L4, L5) may refer to the order in which they are arranged in the direction from the object (S) side toward the image sensor (I). In one embodiment, the first lens (L1) may be referred to as a “first lens on the object (S) side” or a “lens disposed furthest from the image sensor (I),” and the fifth lens (L5) may be referred to as a “first lens on the image sensor (I) side” or a “lens disposed closest to the image sensor (I).” In one embodiment, the image sensor (I) (e.g., the imaging plane (img)) may be aligned to face the lenses (L1, L2, L3, L4, L5) on the optical axis (O). The imaging plane (img) may receive or detect light aligned or focused by, for example, the lenses (L1, L2, L3, L4, L5).

[0125] According to one embodiment, an optical component such as an infrared cut filter (F) may be disposed between at least one of five lenses (L1, L2, L3, L4, L5) and the image sensor (I). The infrared cut filter (F) may be disposed between the fifth lens (L5) and the image sensor (I). The infrared cut filter (F) may suppress or block light (e.g., infrared) of a wavelength that is not visible to the naked eye of a user but is detected by a photosensitive material or the image sensor (I) from entering the image sensor (I). Depending on the intended use of the camera module (400), the infrared cut filter (F) may be replaced with a bandpass filter that transmits infrared and suppresses or blocks visible light. In one embodiment, the infrared cut filter (F) may be implemented by a coating material disposed on a surface of any one of the lenses (L1, L2, L3, L4, L5).

[0126] According to one embodiment, as will be described with reference to embodiments such as FIG. 6, the camera module (400) and / or the lens assembly (LA) may include an aperture (e.g., the aperture (sto) of FIG. 6) disposed between the first lens (L1) and the fifth lens (L5). In the embodiment of FIG. 6, the aperture may be understood to be disposed between the first lens (L1) and the second lens (L2). In one embodiment, the aperture may be disposed in front of the first lens (L1) or behind the fifth lens (L5). Here, “disposed in front of the first lens (L1)” may refer to the first lens (L1) being disposed between the aperture and the image sensor (I). In one embodiment, “disposed behind the fifth lens (L5)” may refer to the aperture being disposed between the fifth lens (L5) and the image sensor (I). In the embodiments described below, it may be mentioned that the aperture is disposed between the n-th lens and the n+1-th lens (wherein 'n' is a natural number). This may refer to the aperture being disposed in the gap or space between the n-th lens and the n+1-th lens. In one embodiment, 'disposed between the n-th lens and the n+1-th lens' may be understood to include a structure disposed on the sensor-side surface of the n-th lens or the object-side surface of the n+1-th lens.

[0127] According to one embodiment, FIG. 5 may exemplify variables for describing the manufacturing specifications of a camera module (500) and / or a lens assembly (LA). For example, 'TTL (total track length)' may exemplify the overall length of a lens, and may be the distance from the upper surface (TS) of the barrel (B) that mounts or supports the lenses (L1, L2, L3, L4, L5) to the image sensor (I) (e.g., imaging plane (img)) measured parallel to the optical axis (O). In one embodiment, 'OAL (overall length)' may be understood as the distance from the vertex of the object-side surface (e.g., the surface indicated by 'S2' in FIG. 6) of the first lens (L1) to the image sensor (I) (e.g., imaging plane (img)) measured parallel to the optical axis (O).

In one embodiment, 'L1_ape' may be an example of an effective radius of the first lens (L1), and may be understood as the radius of an area where light incident on the image sensor (I) passes through the first lens (L1). The effective radius may be measured, for example, along a direction perpendicular to the optical axis (O) from the optical axis (O). In one embodiment, the variable indicated by 'TA' may refer to a distance from the object-side surface vertex of the first lens (L1) (e.g., the surface indicated by 'S2' in FIG. 6) to the sensor-side surface vertex of the fifth lens (L5) (e.g., the surface indicated by 'S13' in FIG. 6), and may be an example of a distance measured from the optical axis (O). In one embodiment, 'T4' represents the central thickness of the fourth lens (L4), which may be, for example, a distance (or gap) measured between the object-side surface of the fourth lens (L4) (e.g., the surface indicated by 'S10' in FIG. 6) and the sensor-side surface of the fourth lens (L4) (e.g., the surface indicated by 'S11' in FIG. 6) on the optical axis (O).In one embodiment, 'IH' may represent the maximum image height of the image sensor (I). The image height of the image sensor (I) may refer to the distance measured perpendicular to the optical axis (O) from a point where the optical axis (O) intersects the active area (e.g., the imaging plane (img)). The maximum image height of the image sensor (I) may be, for example, half the diagonal length of the imaging plane (img). Unless otherwise specified, the variable(s) mentioned in the embodiments described below may be understood with reference to the embodiment of FIG. 5.

FIG. 8 is a graph showing astigmatism of a camera module (500) and / or a lens assembly (LA) according to an embodiment of the present disclosure, for light having a wavelength of 546.0740 nm, where 'X' or 'S' represents a sagittal plane with a solid line, and 'Y' or 'T' represents a tangential plane (or meridional plane) with a dotted line. FIG. 9 is a graph showing distortion of a camera module (500) and / or a lens assembly (LA) according to an embodiment of the present disclosure, for light having a wavelength of 546.0740 nm. The refractive index of the lens(es) mentioned in the embodiment described below may refer to the refractive index for light having a wavelength of approximately 587.5618 nm.

[0130] In the detailed description of the embodiments 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) 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 is curved 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 is curved in such a way that the lens thickness increases as it approaches the optical axis (O) in the paraxial region. In one embodiment, when the object-side surface or the sensor-side surface includes an inflection point (IP), the negative / positive radii of curvature in the paraxial region and the peripheral region may be reversed. In this case, the concaveness or convexity of the lens surface shape can be mentioned by specifying a portion of the lens surface.

[0131] According to one embodiment, among at least five lenses (L1, L2, L3, L4, L5), the first lens (L1) may be, as mentioned above, the first lens on the object (S) side or the lens arranged farthest from the image sensor (I), and may have a meniscus shape convex toward the object (S). In one embodiment, the first lens (L1) may have negative refractive power. In one embodiment, the first lens (L1) may be an aspherical lens. In one embodiment, the first lens (L1) may be a plastic lens and may have a refractive index of approximately 1.55 or less.

[0132] According to one embodiment, among at least five lenses (L1, L2, L3, L4, L5), the second lens (L2) is closest to the first lens (L1) and is positioned between the first lens (L1) and the image sensor (I), and may have a biconvex shape. For example, the second lens (L2) may include a convex object-side surface (S5) and a convex sensor-side surface (S6). In one embodiment, the second lens (L2) may have positive refractive power. In one embodiment, the second lens (L2) may be an aspherical lens. In one embodiment, the second lens (L2) may be a plastic lens and may have a refractive index of approximately 1.55 or less.

[0133] According to one embodiment, the third lens (L3) among at least five lenses (L1, L2, L3, L4, L5) may be disposed second closest to the first lens (L1) and between the first lens (L1) and the image sensor (I). For example, the third lens (L3) may be understood as being disposed between the second lens (L2) and the image sensor (I). In one embodiment, the third lens (L3) may have negative refractive power. In one embodiment, the third lens (L3) may be an aspherical lens. In one embodiment, the third lens (L3) may be a plastic lens and may have a refractive index of about 1.6 or greater (e.g., about 1.66). In one embodiment, the third lens (L3) may include at least one inflection point (IP) on the object-side surface (S8). For example, when the object-side surface (S8) of the third lens (L3) is convex in the region between the optical axis (O) and the inflection point (IP), the region between the inflection point (P) and the edge may be concave. In one embodiment, the sensor-side surface (S9) of the third lens (L3) may be concave.

[0134] According to one embodiment, the fourth lens (L4) is disposed between the third lens (L3) among at least five lenses (L1, L2, L3, L4, L5) and the image sensor (I), and may have a positive refractive power. In one embodiment, the fourth lens (L4) may be a plastic lens having a refractive index of approximately 1.55 or less. In one embodiment, the fourth lens (L4) may be an aspherical lens. In one embodiment, the object-side surface (S10) of the fourth lens (L4) may have a convex shape, and the sensor-side surface (S11) of the fourth lens (L4) may have a convex shape. In one embodiment, the fourth lens (L4) may have a shape in which a thickness gradually decreases as it approaches an edge.

[0135] According to one embodiment, the fifth lens (L5) may be a lens that is arranged closest to the image sensor (I) among at least five lenses (L1, L2, L3, L4, L5). For example, the fifth lens (L5) may be arranged between the first lens (L1) and the image sensor (I) (or between the fourth lens (L4) and the image sensor (I)) and may have negative refractive power. In one embodiment, the fifth lens (L5) may be a plastic lens having a refractive index of about 1.6 or more (e.g., about 1.61). In one embodiment, when the fifth lens (L5) provides high refractive performance, it may lower the chief ray angle (CRA) and provide an environment in which chromatic aberration correction is easy. In one embodiment, the fifth lens (L5) may be an aspherical lens. In one embodiment, the fifth lens (L5) may have a meniscus shape that is convex toward the object (S). In one embodiment, the fifth lens (L5) may have a meniscus shape in which the axial region is convex toward the object (S), and the peripheral region may have a shape inclined toward the object (S). For example, the object-side surface (S12) of the fifth lens (L5) and / or the sensor-side surface (S13) of the fifth lens (L5) may include at least one inflection point (IP, IP1, IP2). In one embodiment, by the fifth lens (L5) including the inflection point (IP, IP1, IP2), the angle of light incident on the image sensor (I) is suppressed from increasing, and various aberration corrections or securing of a peripheral light ratio may be facilitated.

[0136] According to one embodiment, the object-side surface (S12) of the fifth lens (L5) may include two inflection points (IP1, IP2). For example, on the object-side surface (S12), an area between a first inflection point indicated as 'IP1' and a second inflection point indicated as 'IP2' may have a concave shape as a substantially peripheral area of ​​the fifth lens (L5), and an area between the first inflection point (IP1) and the optical axis (O) may have a convex shape. In one embodiment, in an area between the second inflection point (IP2) and the edge of the fifth lens (L5), the object-side surface (S12) of the fifth lens (L5) may have a convex shape. When the object-side surface (S12) of the fifth lens (L5) is defined as having a positive radius of curvature in the region(s) between the optical axis (O) and the first inflection point (IP) (or between the second inflection point (IP2) and the edge of the fifth lens (L5)), for example, the object-side surface (S12) of the fifth lens (L5) can be understood as having a negative radius of curvature in the region between the first inflection point (IP1) and the second inflection point (IP2). In the embodiment(s) of the present disclosure, unless otherwise stated, the 'inflection point (IP)' can be understood to include the first inflection point (IP1) and the second inflection point (IP2). When the object-side surface (S12) of the fifth lens (L5) includes two inflection points (IP1, IP2), an environment in which curvature in the periphery can be easily corrected can be provided.

[0137] In one embodiment, the sensor-side surface (S13) of the fifth lens (L5) may include one inflection point (IP). For example, the region between the optical axis (O) and the inflection point (IP) on the sensor-side surface (S13) of the fifth lens (L5) may have a concave shape, and the region from the inflection point (IP) to the edge of the fifth lens (L5) may have a convex shape. Accordingly, the fifth lens (L5) may have a meniscus shape that is convex toward the object (S) in the paraxial region, and the peripheral region may have a shape that is inclined toward the object (S) as it approaches the edge. In one embodiment, the shape of the fifth lens (L5) as described above may provide an environment that facilitates peripheral curvature correction while reducing the lens overall length (e.g., 'TTL' in FIG. 5) in the camera module (500) and / or the lens assembly (LA). In one embodiment, when a fifth lens (L5) having a negative refractive power and becoming thicker as it approaches the edge is combined with a fourth lens (L4) having a positive refractive power and becoming thinner as it approaches the edge, the camera module (500) and / or lens assembly (LA) can provide good optical performance for a reference distance considered in the design, a distance longer than the reference distance, and / or close-up photography of approximately 3 cm or less.

[0138] In the illustrated embodiment, an infrared cut filter (F) is positioned between the fifth lens (L5) and the image sensor (I), thereby blocking light of a designated wavelength band. As mentioned above, the term "light of a designated wavelength band" may refer to light of a wavelength that is not visible to the user's naked eye but is detected by a photosensitive material or the image sensor (I).

[0139] In one embodiment, the camera module (500) and / or the lens assembly (LA) may include an aperture (sto) disposed between the first lens (L1) and the second lens (L2). As previously mentioned, “between the first lens (L1) and the second lens (L2)” may be understood to include the sensor-side surface (S3) of the first lens (L1) and the object-side surface (S5) of the second lens (L2). In one embodiment, the specification or position of the aperture (sto) may determine the brightness of the lens assembly (LA), for example, the F-number (Fno). In one embodiment, the aperture (sto) may be disposed between the first lens (L1) and the second lens (L2), thereby stabilizing optical performance such as securing a relative illumination (RI) ratio or controlling aberrations. In one embodiment, the aperture (sto) may be positioned between the first lens (L1) and the second lens (L2), thereby facilitating reduction of the overall size of the lens assembly (LA) and / or the outer diameter of the first lens (L1).

[0140] According to one embodiment, a processor (e.g., processor (120) of FIG. 1) or an image signal processor (e.g., image signal processor (260) of FIG. 2) can acquire an image of a subject (e.g., object (S)) by detecting light focused or guided by a lens assembly (LA) using an image sensor (I). 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) 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) 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 (e.g., the electronic device (101, 102, 104, 200, 300 of FIGS. 1 to 6) 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 the instructions stored in the memory (e.g., the memory (130) of FIG. 1). For example, the instructions for causing the electronic device to receive at least a portion of the light focused on the image sensor (I) and to acquire an image of an object (S) based on the received light may be stored in the memory, and these instructions may be executed by the processor (s).

[0141] 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) or the lens surfaces based on the lens data presented through the [Tables] described below. For the sake of brevity of the drawings, the reference numbers in the drawings for some of the object-side surface(s) and the sensor-side surface(s) of the lenses (L1, L2, L3, L4, L5) and / or the inflection point (IP) may be omitted. The 'inflection point (IP)' refers to a point where the radius of curvature changes and is a portion that does not intersect the optical axis (O) on the object-side surface(s) and the sensor-side surface(s), 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.

[0142] In the detailed description below, values ​​for the radius (e.g., radius of curvature), effective focal length (f), TTL (total track length), air gap, thickness or image height of the image sensor (I) of the lenses (L1, L2, L3, L4, L5) of the present disclosure, including the variables examined with reference to FIG. 5, may all have units of mm unless otherwise specified. 'TTL' may be 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), which may be measured parallel to the optical axis (O). In addition, the radius of curvature, effective focal length, TTL, air gap or thickness of the lenses (L1, L2, L3, L4, L5) may be a distance measured parallel to the optical axis (O), and / or the effective radius and the image height 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.

[0143] According to one embodiment, the camera module (500) and / or its lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 1]. [Mathematical Formula 1] may present conditions regarding, for example, the lens total length 'TTL' of the camera module (500) and / or the lens assembly (LA) and the maximum height 'IH' of the image sensor (I).

[0144]

[0145] In one embodiment, when the calculated value of [Mathematical Formula 1] is greater than approximately 0.9, the lens total length 'TTL' increases, which may make it difficult to miniaturize the camera module (500) and / or the lens assembly (LA). In one embodiment, when the calculated value of [Mathematical Formula 1] is less than approximately 0.7, the camera module (500) and / or the lens assembly (LA) may be miniaturized, but there may be difficulty in processing or assembling the lenses (L1, L2, L3, L4, L5). For example, [Mathematical Formula 1] may present conditions under which the camera module (500) and / or the lens assembly (LA) may be miniaturized to a degree that they can be mounted on miniaturized electronic devices such as smart phones, while suppressing an increase in manufacturing cost, difficulty of the manufacturing process, and / or time required for manufacturing. In one embodiment, when the condition of [Mathematical Formula 1] is satisfied, the lens assembly (LA) and / or the camera module (500) can be miniaturized, facilitating the implementation of optical performance suitable for a high-performance, large-size image sensor of about 50 megapixels or more. In one embodiment, the camera module (500) and / or the lens assembly (LA) can satisfy a range of about 0.85 or more and about 0.9 or less in the value calculated by [Mathematical Formula 1].

[0146] According to one embodiment, the camera module (500) and / or its lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 2] regarding the focal length (e.g., total effective focal length) 'Efl' and the maximum elevation 'IH' of the lens assembly (LA).

[0147]

[0148] In one embodiment, when the camera module (500) and / or the lens assembly (LA) satisfies the condition of [Mathematical Formula 2], it may be easy to implement an optical system with a magnification of approximately X0.6. For example, the total effective focal length may be shortened, and it may be easy to implement wide-angle performance and / or ultra-wide-angle performance. In one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy a range of approximately 0.65 or more and approximately 0.71 or less in the calculated value by [Mathematical Formula 2].

[0149] According to one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 3]. [Mathematical Formula 3] presents conditions regarding, for example, a ratio of a center thickness 'T4' of the fourth lens (LA) and a distance 'TA' from an object-side surface (S2) of the first lens (L1) to a sensor-side surface (S13) of the fifth lens (L5), and the center thickness 'T4' and the distance 'TA' may be values ​​measured from the optical axis (O).

[0150]

[0151] In one embodiment, when the condition presented through [Mathematical Formula 3] is satisfied, the camera module (500) and / or the lens assembly (LA) can provide good optical performance not only at the reference distance considered in the design phase, but also at a distance longer than the reference distance and / or for close-up photography. In one embodiment, by satisfying the condition of [Mathematical Formula 3], the camera module (500) and / or the lens assembly (LA) can be miniaturized while suppressing stray light (or flare). For example, when the calculated value of [Mathematical Formula 3] is greater than approximately 0.19, the thickness of the fourth lens (L4) increases, which may make it difficult to miniaturize the lens assembly (LA). In one embodiment, when the calculated value of [Mathematical Formula 3] is greater than approximately 0.19, the total reflection phenomenon and / or stray light may increase at the lens surface of the fourth lens (L4), which may deteriorate the image quality. In one embodiment, when the calculated value of [Mathematical Formula 3] becomes less than approximately 0.1, the lens assembly (LA) may be miniaturized, but the thickness of individual lenses may become thinner, increasing the difficulty of processing, and / or difficulty may occur in assembling the lenses (L1, L2, L3, L4, L5). In one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy a range of approximately 0.175 or more and approximately 0.185 or less in the calculated value by [Mathematical Formula 3].

[0152] According to one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 4]. [Mathematical Formula 4] may present conditions regarding, for example, the effective radius 'L1_ape' of the first lens (L1) and the maximum height 'IH' of the image sensor (I).

[0153]

[0154] In one embodiment, when the camera module (500) and / or the lens assembly (LA) satisfies the condition of [Mathematical Formula 4], the effective radius of the first lens (L1) may be reduced. For example, when the lens assembly (LA) satisfies the condition of [Mathematical Formula 4], the external size of the camera module (500) and / or the size of the camera module (500) visible from the exterior of the electronic device (e.g., the electronic device (300) of FIG. 4) may be reduced, and the degree of design freedom in the exterior of the electronic device may be increased. In one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy a range of approximately 0.35 or more and approximately 0.4 or less in the value calculated by [Mathematical Formula 4].

[0155] According to one embodiment, the camera module (500) and / or its lens assembly (LA) may satisfy the condition presented through the following [Mathematical Formula 5]. [Mathematical Formula 5] may present a condition regarding, for example, the brightness (e.g., F-number (Fno)) of the lens assembly (LA). When the condition presented through [Mathematical Formula 5] is satisfied, the camera module (500) and / or the lens assembly (LA) may be miniaturized using approximately five lenses (L1, L2, L3, L4, L5) while implementing good optical performance (e.g., resolution). For example, when the F-number exceeds approximately 2.4, optical performance in terms of brightness or resolution may deteriorate, and when the F-number becomes smaller than approximately 2.0, an increase in the number of lenses is inevitable, which may make miniaturization difficult. In one embodiment, the F-number of the camera module (500) and / or the lens assembly (LA) may satisfy a range of about 2.2 or greater and about 2.3 or less.

[0156]

[0157] According to one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 6]. [Mathematical Formula 6] may, for example, present conditions regarding the field of view 'FOV' of the camera module (500) and / or the lens assembly (LA).

[0158]

[0159] In one embodiment, when the angle of view of the lens assembly (LA) exceeds approximately 140 degrees, the focal length may decrease, which may be advantageous for miniaturization, but may have difficulty in securing peripheral light. In one embodiment, when the angle of view of the lens assembly (LA) is smaller than approximately 110 degrees, securing peripheral performance may be advantageous, but miniaturization may be difficult as the focal length increases, and it may be difficult to secure ultra-wide-angle performance. In one embodiment, the angle of view of the camera module (500) and / or the lens assembly (LA) may be in a range of approximately 115 degrees or more and 125 degrees or less.

[0160] According to one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy the conditions presented by the following [Mathematical Expression 7]. [Mathematical Expression 7] may, for example, present conditions regarding the shape (e.g., the radius of curvature of the lens surfaces) or the refractive power of the fourth lens (L4). In one embodiment, the camera module (500) and / or the lens assembly (LA) may satisfy a range of about 1.0 or more and about 1.2 or less in the value calculated by [Mathematical Expression 7].

[0161]

[0162] Here, 'r7' may be the radius of curvature of the point where the object-side surface (S10) of the fourth lens (L4) intersects the optical axis (O), and 'r8' may be the radius of curvature of the point where the sensor-side surface (S11) of the fourth lens (L4) intersects the optical axis (O). In one embodiment, when the condition of [Mathematical Formula 7] is satisfied, aberration control in the peripheral area may be easy, and the lens assembly (LA) may have good optical performance not only in shooting at a reference distance considered in the design stage but also in shooting at a distance longer than the reference distance or in close-up shooting. When the condition of [Mathematical Formula 7] is satisfied, the total reflection phenomenon and / or stray light occurring in the lens surfaces (S10, S11) of the fourth lens (L4) may be suppressed. In one embodiment, the fifth lens (L5) may have a shape and refractive power different from or opposite to those of the fourth lens (L4). For example, when the fourth lens (L4) satisfies the condition of [Mathematical Formula 7], the shape of the fifth lens (L5) can compensate for the reduced resolution between approximately 0.5 fields and approximately 0.6 fields. In one embodiment, when the calculated value of [Mathematical Formula 7] is less than approximately 0.5, stray light due to total reflection between the lens surfaces of the fourth lens (L4) may increase. In one embodiment, when the calculated value of [Mathematical Formula 7] is greater than approximately 1.5, the refractive power of the fourth lens (L4) increases, and it may be difficult to secure the refractive power of the fifth lens (L5) corresponding to the increased refractive power of the fourth lens (L4). In one embodiment, when the refractive power of the fourth lens (L4) increases and an appropriate refractive power is not secured in the fifth lens (L5), it may be difficult to secure the modulation transfer function (MTF) performance of the lens assembly (LA).

[0163] According to one embodiment, the camera module (500) and / or its lens assembly (LA) may have a focal length of approximately 1.97 mm, an F-number of approximately 2.28, and an angle of view of approximately 120 degrees. In one embodiment, the camera module (500) and / or its lens assembly (LA) may satisfy at least some of the above-described condition(s) including [Mathematical Formula 1-7], and may be manufactured with the specifications exemplified in the following [Table 1]. In the following [Table 1], at least one of the lens surfaces may be aspherical, and the lens surface corresponding to the aspherical surface will be more clearly understood through the [Tables] regarding aspherical coefficients described below. The aperture 'sto' may be arranged between the first lens (L1) and the second lens (L2). The term “between the first lens (L1) and the second lens (L2)” may be generally understood as the space between the first lens (L1) and the second lens (L2), but it should be noted that the embodiment(s) of the present disclosure are not limited thereto. For example, the term “between the first lens (L1) and the second lens (L2)” may be understood to include the sensor-side surface (S3) of the first lens (L1) and the object-side surface (S5) of the second lens (L2).

[0165] [Table 2], [Table 3], and [Table 4] below list the aspherical coefficients of lenses (L1, L2, L3, L4, L5), and the definition of aspherical is as follows [Mathematical Formula 8].
