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] An electronic device can refer to any device that performs a specified function according to a built-in program, such as a home appliance, an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, an audio / video device, a desktop / laptop computer, or an in-vehicle navigation system. For example, these electronic devices can output stored information as audio or video. As the integration of electronic devices increases and ultra-high-speed, high-capacity wireless communication becomes more widespread, a single electronic device, such as a mobile communication terminal, can now be equipped with various functions. For example, in addition to communication functions, entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions for mobile banking, and / or functions such as schedule management or electronic wallets are being integrated into a single electronic device.

[0003] As digital camera technology developed, electronic devices equipped with compact, lightweight camera modules became commercially available. With camera modules integrated into electronic devices we typically carry with us (e.g., mobile terminals), users could conveniently utilize a variety of features, including not only taking photos and videos, but also video calling and augmented reality.

[0004] Recently, electronic devices that incorporate multiple cameras have become widespread. These devices may, for example, include camera modules that include a wide-angle camera and a telephoto camera. The wide-angle camera can capture a wide-angle image by capturing a scene surrounding the device, or the telephoto camera can capture a scene relatively distant from the device, capturing a telephoto image. Miniaturized electronic devices, such as smartphones, are increasingly encroaching on the digital compact camera market by incorporating multiple camera modules or imaging devices, and are expected to eventually replace high-performance cameras such as single-lens reflex cameras.

In one embodiment, such a camera module may satisfy [Conditional Expression 1; 2.5 <= f / IH <= 20] regarding a focal length 'f' of the lens assembly and a maximum image height 'IH' of the image sensor. In one embodiment, the units of the focal length 'f' and the maximum elevation 'IH' may be 'mm'.

[0007] According to one embodiment of the present disclosure, an electronic device may include a camera module, at least one processor, and a memory storing instructions configured to cause the electronic device to acquire an image of a subject using the camera module when executed by the at least one processor. In one embodiment, the camera module may include at least one lens aligned along an optical axis, a lens assembly including an optical member, and an image sensor configured to detect light focused or guided by the lens assembly.

[0054] As electronic devices become smaller and / or lighter, they can become more portable. In an environment where displays are becoming larger to enable greater screen enjoyment on portable electronic devices, electronic devices can become smaller and lighter by reducing their thickness. However, miniaturized electronic devices may face difficulties in integrating imaging devices with good optical performance. For example, while securing optical performance of an imaging device with a larger number or size of lenses can be easier, miniaturized electronic devices may experience reduced design freedom in the arrangement of lenses or image sensors. When installed in miniaturized electronic devices, telephoto cameras may face difficulties in securing a sufficient number of lenses for aberration correction performance.

[0055] One embodiment of the present disclosure is intended to at least resolve the above-described problems and / or disadvantages and at least provide the advantages described below, thereby providing an optical system, a camera module, and / or an electronic device including the same that is easy to miniaturize while providing good image quality.

[0056] One embodiment of the present disclosure can provide an optical system, a camera module, and / or an electronic device including the same that can be easily placed in a narrow space.

When a component (e.g., a first component) is referred to as being “coupled” or “connected” to another component (e.g., a second component), with or without the terms “functionally” or “communicatively,” it is understood that the component can be connected to the other component directly (e.g., wired), wirelessly, or via a third component.

[0085] The term "module" used in the embodiments of the present disclosure may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0086] Embodiments of the present disclosure may be implemented as software (e.g., a program) including one or more instructions stored in a storage medium (e.g., built-in memory or external memory) readable by a machine (e.g., an electronic device). For example, a processor (e.g., a processor) of the machine (e.g., an electronic device) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one instruction called. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, "non-transitory" only means that the storage medium is a tangible device and does not contain a signal (e.g., electromagnetic waves), and this term does not distinguish between cases where data is stored semi-permanently and cases where it is stored temporarily in the storage medium.

[0087] According to one embodiment, a method according to the embodiment(s) of the present disclosure may be provided as a computer program product. The computer program product may be traded between sellers and buyers as a product. The computer program product may be distributed in the form of a device-readable storage medium (e.g., compact disc read only memory (CD-ROM)) or may be provided through an application store (e.g., Play Store). TM ) or directly between two user devices (e.g., smartphones), online distribution (e.g., downloading or uploading). In the case of online distribution, at least a portion of the computer program product may be at least temporarily stored or temporarily created in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0088] According to one embodiment, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to one embodiment, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In such a case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to one embodiment, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

[0089] In the detailed description below, the longitudinal direction, the width direction, and / or the thickness direction of the electronic device may be mentioned, and the longitudinal direction may be defined as the 'Y-axis direction', the width direction as the 'X-axis direction', and / or the thickness direction as the 'Z-axis direction'. In one embodiment, with respect to the direction that a component is oriented, 'negative / positive (- / +)' may be mentioned together with the rectangular coordinate system illustrated in the drawings. For example, the front of the electronic device and / or the housing may be defined as the 'side facing the +Z direction', and the back side may be defined as the 'side facing the -Z direction'. In one embodiment, the side of the electronic device and / or the housing may include a region facing the +X direction, a region facing the +Y direction, a region facing the -X direction, and / or a region facing the -Y direction.

[0109] In the detailed description below, reference may be made to the electronic devices (101, 102, 104, 200, 300) of the preceding embodiments, and it is noted that the same reference numbers in the drawings may be given or omitted for configurations that can be easily understood through the preceding embodiments, and the detailed description thereof may also be omitted.

[0110] FIG. 5 is a plan view illustrating a rear surface of an electronic device (400) (e.g., the electronic devices (101, 102, 104, 200, 300) of FIGS. 1 to 4 ) according to one embodiment of the present disclosure. FIG. 6 is a cross-sectional view illustrating a portion of the electronic device (400) according to one embodiment of the present disclosure taken along line A-A' of FIG. 5 . FIG. 7 is a configuration diagram illustrating an optical path of a camera module (500) in an electronic device (400) according to one embodiment of the present disclosure.

[0111] Referring to FIGS. 5 and 6, an electronic device (400) according to an embodiment of the present disclosure may include a camera window (385) disposed on one surface (e.g., the second surface (210B) of FIG. 3). In one embodiment, the camera window (385) may be a part of a rear plate (380). In one embodiment, the camera window (385) may be coupled to the rear plate (380) through a decorative member (389), and when viewed from the outside, the decorative member (389) may be exposed in a form that surrounds the periphery of the camera window (385). According to one embodiment, the camera window (385) may include a plurality of transparent regions (387), and the electronic device (400) may receive external light or radiate light to the outside through at least one of the transparent regions (387). For example, the electronic device (400) may include at least one camera module (500) (e.g., camera modules (180, 205, 212, 213) of FIGS. 1 to 3) arranged to correspond to at least some of the transparent areas (387), and at least one light source (e.g., an infrared light source) arranged to correspond to another part of the transparent areas (387). In one embodiment, the camera module (500) or the light source may receive external light or radiate light to the outside of the electronic device (400) through any one of the transparent areas (387). In one embodiment, the electronic device (400) or the camera module (500) may further include a camera support member (381). The camera support member (381) may be positioned or fixed to the inside of the rear plate (380) or the camera window (385) to support at least one of the camera module (500) or other imaging devices adjacent thereto (e.g., a wide-angle camera, an ultra-wide-angle camera, or a macro camera). In one embodiment, the camera support member (381) may be substantially a part of the first support member (311) or the second support member (360) of FIG. 4.

[0112] According to one embodiment, the electronic device (400) may include at least one of a wide-angle camera, an ultra-wide-angle camera, a close-up camera, a telephoto camera, or an infrared photodiode as a camera module (500) or a light-receiving element, and may include a flash (e.g., the flash (213) of FIG. 3) or an infrared laser diode as a light source or a light-emitting element. In one embodiment, the electronic device (400) may detect a distance to a subject by emitting an infrared laser toward the subject and receiving an infrared laser reflected by the subject using the infrared laser diode and the infrared photodiode. In one embodiment, the electronic device (400) may capture a subject by using one or a combination of two or more of the cameras, and may provide illumination toward the subject by using a flash as needed.

[0113] According to one embodiment, among the cameras, a wide-angle camera, an ultra-wide-angle camera, or a macro camera may have a shorter length in the optical axis direction of the lens(es) compared to a telephoto camera (e.g., camera module (500)). For example, a telephoto camera (e.g., camera module (500)) having a relatively large focal length may have a larger lens length of the lenses (423a, 423b, 423c)(s) than other cameras. The term “lens length” may be the distance from the object-side surface of the first lens on the object side to the imaging surface of the image sensor (411). In the case where other optical members (e.g., mirrors or prisms) are arranged between the lens(es) and the image sensor, as in the embodiment described below (e.g., imaging device (600) of FIG. 8), the “lens length” may be 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.

[0114] In one embodiment, the wide-angle camera, ultra-wide-angle camera, or macro camera may have a substantially small effect on the thickness of the electronic device (400) even if the lens(es) are arranged along the thickness direction of the electronic device (400) (e.g., the thickness measured in the Z-axis direction of FIG. 4 or FIG. 6). For example, the wide-angle camera, ultra-wide-angle camera, or macro camera may be arranged in the electronic device (400) such that the direction in which light is incident on the electronic device (400) from the outside and the optical axis direction of the lens(es) are substantially the same. In one embodiment, compared to the wide-angle camera, ultra-wide-angle camera, or macro camera, the camera module (500) (e.g., a telephoto camera) may have a smaller angle of view, but may be useful for photographing subjects at a longer distance, and may include more lenses (421a, 421b, 423a, 423b, 423c). For example, when the lenses (423a, 423b, 423c) of the camera module (500) are arranged in the thickness direction (e.g., Z-axis direction) of the electronic device (400), the thickness of the electronic device (400) may increase, or the camera module (500) may protrude significantly outward from the electronic device (400). In one embodiment of the present disclosure, the camera module (500) may include at least one optical member (e.g., refractive member (413, 415)) that reflects or refracts incident light (IL) in another direction. In implementing a telephoto function, the lenses (423a, 423b, 423c) may be arranged to be able to move forward and backward in the incident direction of the light or the traveling direction of the reflected or refracted light, thereby suppressing or reducing an increase in the thickness of the electronic device (400).

[0115] Referring to FIGS. 6 and 7, a folded camera (e.g., a camera module (500)) may include a first refractive member (413), a second refractive member (415), an image sensor (411), and / or at least one lens system (e.g., a second lens group (423) including second lenses (423a, 423b, 423c) or a dummy member (423d)). A 'folded camera' may be useful for expanding the range of adjustment of the focal length. For example, in a folded camera, a reflective member such as a prism or a mirror is arranged, so that the design or arrangement of the direction in which the lenses are arranged can be free regardless of the direction in which external light is incident. As the design freedom for the arrangement direction of the lenses in the folded camera is improved, a miniaturized telephoto camera can be implemented, and can be mounted on an electronic device in combination with a wide-angle camera. In one embodiment, at least one optical member can guide or focus light (RL1) reflected or refracted by the first refractive member (413) to the second refractive member (415), and can block light (RL1) reflected or refracted by the first refractive member (413) from directly entering the image sensor (411).

[0116] In one embodiment, the first refractive member (413) may include, for example, a prism, a mirror, or a reflective member including a mirror that reflects light. For example, the first refractive member (413) may be formed as a prism including at least one mirror. For example, the first refractive member (413) may be formed as a prism having at least one surface including a mirror. In one embodiment, the first refractive member (413) may reflect or refract light (IL) incident in a first direction (D1) in a second direction (D2) intersecting the first direction (D1). The first direction (D1) may refer to a direction in which light (IL) is incident from the outside onto the electronic device (400) or the camera module (500) through any one of the transparent areas (387) of FIG. 5 when photographing a subject, for example. In one embodiment, the first direction (D1) may mean a shooting direction, a subject direction, an orientation direction of the camera module (500), or a direction parallel thereto. In one embodiment, the first direction (D1) may be parallel to the thickness direction or the Z-axis direction of the electronic device (400).

[0117] In one embodiment, the second refractive member (415) may include, for example, a prism, a mirror, or a reflective member including a mirror that reflects light. For example, the second refractive member (415) may be formed as a prism including at least one mirror. For example, the second refractive member (415) may be formed as a prism having at least one surface including a mirror. In one embodiment, the second refractive member (415) may reflect or refract light (RL1) incident along the second direction (D2) by being reflected or refracted by the first refractive member (413) in a third direction (D3) intersecting the second direction (D2). In one embodiment, the third direction (D3) may be substantially perpendicular to the second direction (D2). For example, the third direction (D3) may mean a direction parallel to the Z-axis direction. However, one embodiment of the present disclosure is not limited thereto, and depending on the arrangement and specifications of the camera module (500) or the second refractive member (415) within the electronic device (400), the third direction (D3) may be an inclined direction with respect to the second direction (D2) or the XY plane. In one embodiment, the third direction (D3) may be substantially parallel to the first direction (D1).

[0118] According to one embodiment, the image sensor (411) may be configured to detect light (RL2) incident along the third direction (D3) by being reflected or refracted by the second refractive member (415). For example, externally incident light (IL) may be detected by the image sensor (411) via the first refractive member (413) and the second refractive member (415), and the electronic device (400) or the camera module (500) may acquire an image of a subject based on a signal or information detected through the image sensor (411). In one embodiment, the image sensor (411) may be arranged substantially parallel to the XY plane. For example, when the camera module (500) has a shake correction function having a structure that shifts the image sensor (411), the image sensor (411) may move horizontally in a plane perpendicular to the first direction (D1) or the third direction (D3).

[0119] According to one embodiment, when performing a shake correction operation, the image sensor (411) may be shifted in the longitudinal direction (e.g., Y-axis direction) or the width direction (e.g., X-axis direction) of the electronic device (400). For example, the image sensor (411) may be arranged on a plane perpendicular to the first direction (D1) or the third direction (D3), so that in an electronic device having a small thickness (e.g., a thickness of approximately 10 mm or less), it may be easy to expand the size of the image sensor (411) and / or it may be easy to secure a space for a shake correction operation. In one embodiment, when the camera module (500) is utilized as a telephoto camera, the quality of the captured image may be further improved by installing a shake correction function. In one embodiment, when the image sensor (411) is enlarged, the performance of the camera module (500) may be further improved.

[0120] According to one embodiment, the camera module (500) may further include a lens system (e.g., a first lens group (421) including at least one first lens (421a, 421b)) that guides or focuses light (IL) incident from a first direction (D1) to a first refractive element (413). In one embodiment, the first lens group (421) or the first lens (e.g., the first lens (421a)) arranged on the object side of the camera module (500) may have a positive refractive power. For example, since the first lens (421a) is configured to focus or align light (IL) incident from the outside to the first refractive element (413), the optical system from the first lens (421a) to the image sensor (411) may be miniaturized. According to an embodiment, the first lens group (421) may further include an additional first lens (421b)(s) for focusing or aligning light incident from the outside.

[0121] According to one embodiment, the second lens group (423) may include a dummy member (423d) and a light-blocking member (425). The dummy member (423d) may be, for example, disposed inside the camera module (500) or the electronic device (400) and may have a cylindrical shape extending along the second direction (D2) and may transmit light (RL1) traveling along the second direction (D2). In one embodiment, the dummy member (423d) may be one of a lens having positive or negative refractive power. In one embodiment, the dummy member (423d) may be a component formed integrally with any one of the second lenses (423a, 423b, 423c) or the second refractive member (415).

[0122] According to one embodiment, the light-blocking member (425) can be formed or arranged on at least a portion of the outer surface of the dummy member (423d) and can absorb, scatter, or reflect light. The light-blocking member (425) can be formed, for example, by performing a corrosion treatment, a black lacquer treatment, and / or by printing or depositing a reflective layer on at least a portion of the outer surface of the dummy member (423d). In one embodiment, a portion of the light reflected or refracted by the first refractive member (413) can be absorbed, scattered, or reflected by the light-blocking member (425). In one embodiment, the light-blocking member (425) can substantially block the light reflected or refracted by the first refractive member (413) from directly entering the image sensor (411) without passing through the second lens group (423) and / or the second refractive member (415). For example, light that has sequentially traveled in the first direction (D1), the second direction (D2), and / or the third direction (D3) in the camera module (500) (e.g., light that follows a path indicated by 'IL, 'RL1', and 'RL2' in FIG. 7) can be incident on the image sensor (411), and light that has traveled in other paths can be substantially blocked from being incident on the image sensor (411).

[0123] According to one embodiment, at least one of the second lenses (423a, 423b, 423c) can move forward and backward along an axis substantially the same as the second direction (D2) between the first refractive element (413) and the second refractive element (415). For example, the electronic device (400) (e.g., the processor (120) of FIG. 1) or the camera module (500) can perform focal length adjustment or focus adjustment by moving at least one second lens (423a, 423b, 423c) forward and backward relative to an axis substantially the same as the second direction (D2). A miniaturized electronic device such as a smart phone may have a thickness of approximately 10 mm, in which case the range in which the lenses can move forward and backward in the thickness direction may be limited.

[0124] According to one embodiment, the second direction (D2) can be substantially parallel to the longitudinal direction (e.g., the Y-axis direction of FIG. 4), the width direction (e.g., the X-axis direction of FIG. 4) and / or the XY plane, and the range in which at least one second lens (423a, 423b, 423c) can move forward and backward can be large compared to a typical wide-angle camera that moves forward and backward in the Z-axis direction for focus adjustment. For example, by having at least one second lens (423a, 423b, 423c) move forward and backward along an axis substantially the same as the second direction (D2), the telephoto performance in the camera module (500) can be improved, while the design freedom in securing the space for moving forward and backward for focal length adjustment or focus adjustment can be improved.

[0125] According to one embodiment, the electronic device (400) and / or the camera module (500) may further include an infrared cut filter (419). In one embodiment, the infrared cut filter (419) may block light in an infrared or near-infrared wavelength band from being incident on the image sensor (411) and may be positioned at any position in the optical path between the first lens (421a) and the image sensor (411). In one embodiment, the infrared cut filter (419) may be positioned close to the image sensor (411) (e.g., between the image sensor (411) and the second refractive member (415), thereby suppressing or preventing the infrared cut filter (419) from being visually exposed to the outside. In one embodiment, the first refractive member (413), the second refractive member (415), and / or at least one optical member (e.g., the second lens group (423)) may include an infrared cut coating layer, in which case the infrared cut filter (419) may be omitted. In one embodiment, an infrared blocking coating layer may be provided on at least one of the image sensor side and the object side of the dummy member (423d) or on the second refractive member (415). As a result, the image sensor (411) can substantially detect light that has passed through the infrared blocking filter (419) (or the infrared blocking coating layer).

[0126] The refractive members (413, 415) of the present disclosure can be selectively designed according to the structure of the camera module (500). For example, in one embodiment, the refractive member (e.g., the second refractive member (415) of FIG. 6) may have a triangular prism shape. In one embodiment, the refractive member (e.g., the second refractive member (415) of FIG. 7) may have a trapezoidal prism shape. The shape of the refractive members (413, 415) is not limited to the structure illustrated in the present disclosure. For example, if the refractive members (413, 415) reflect, refract, or transmit light, the refractive members (413, 415) may have a structure other than a triangular prism or a trapezoidal prism. In one embodiment, the types of the refractive members (413, 415) may be arranged in various ways. For example, the refractive member (e.g., the second refractive member (415) of FIG. 6) may be arranged as a prism. For example, the refractive member (e.g., the second refractive member (415) of FIG. 7) may be arranged as a mirror. For example, the refractive members (413, 415) may include a substantially transparent material. For example, the refractive members (413, 415) may be manufactured using glass.

[0127] The camera modules (180, 205, 212, 213, 500) of the above-described FIGS. 1 to 7 may be implemented by at least one of the camera modules (600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500) of the following FIGS. 8, 12, 16, 20, 24, 28, 32, 33, 37 and / or 41. Therefore, in the detailed description below, reference may be made to the electronic devices (101, 102, 104, 200, 300, 400) of the preceding embodiments, and it should be noted that the same reference numerals in the drawings may be given or omitted for configurations that can be easily understood through the preceding embodiments, and a detailed description thereof may also be omitted.

[0128] In the above-described embodiment, a camera module (500) including a plurality of lens groups (421, 423) and a plurality of refractive elements (413, 415) is illustrated, but it should be noted that the embodiment(s) of the present disclosure are not limited thereto. For example, any one of the plurality of lens groups (421, 423) or any one of the plurality of refractive elements (413, 415) may be omitted, and the camera module (500) may further include an additional lens group or an additional refractive element that is not shown. For example, a camera module according to an embodiment(s) of the present disclosure may be understood to include at least one lens group and at least one optical element (e.g., the refractive element (413, 415)). In one embodiment, in a camera module according to an embodiment(s) of the present disclosure, at least one optical element may have positive refractive power or negative refractive power. For example, in securing the optical performance of an optical system or a camera module, at least one optical element may function as a lens(es). By having at least one optical element function as a lens, the optical system and / or camera module can be easily miniaturized while achieving the same optical performance. In one embodiment, when at least one optical element has refractive power while reflecting (or refracting) incident light at least once, it can be useful for implementing a miniaturized telephoto camera.

[0129] FIG. 8 is a diagram illustrating a camera module (600) and / or a lens assembly (LA) according to an embodiment of the present disclosure. FIG. 9 is a graph illustrating spherical aberration of the lens assembly (LA) of FIG. 8 according to an embodiment of the present disclosure. FIG. 10 is a graph illustrating astigmatism of the lens assembly (LA) of FIG. 8 according to an embodiment of the present disclosure. FIG. 11 is a graph illustrating a distortion ratio of the lens assembly (LA) of FIG. 8 according to an embodiment of the present disclosure.

[0130] FIG. 9 is a graph showing spherical aberration of a camera module (600) and / or a lens assembly (LA) according to one embodiment of the present disclosure, in which the horizontal axis represents a coefficient of longitudinal spherical aberration, the vertical axis represents a normalized distance from the optical axis, and the change in longitudinal spherical aberration according to the wavelength of light is shown. The longitudinal spherical aberration is shown for light having wavelengths of, for example, 656.3000 (NM, nanometer), 587.6000 (NM), 546.1000 (NM), 486.1000 (NM), and 435.8000 (NM), respectively. FIG. 10 is a graph showing astigmatism of a camera module (600) and / or a lens assembly (LA) according to one embodiment of the present disclosure, for light having a wavelength of 546.1000 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. 11 is a graph showing distortion of a camera module (600) and / or a lens assembly (LA) according to one embodiment of the present disclosure, for light having a wavelength of 546.1000 nm. When the refractive index of the lens(es) is mentioned in the embodiments described below, this may refer to the refractive index for light having a wavelength of approximately 587.6000 nm. In the following description, the camera module (600)(s) is a structure including at least one optical member (e.g., a prism or a mirror) disposed between the lens (L1, L2, L3, L4)(s) and the image sensor (I), or at least one optical member disposed in front of the lens (L1, L2, L3, L4)(s), and it is noted that in a graph regarding spherical aberration, astigmatism, and / or distortion rate, the negative / positive may be reversed depending on the number of times light is reflected and / or refracted by the optical member.

[0131] Referring to FIGS. 6 to 8, a camera module (600) according to an embodiment of the present disclosure may include an image sensor (I) and a lens assembly (LA). The lens assembly (LA) may include, for example, at least one (e.g., four) lens (L1, L2, L3, L4) and at least one optical member (OM). The at least one optical member (OM) may include, for example, an optical member (e.g., a second refractive member (415) of FIG. 6 or 7) disposed between at least one lens (L1, L2, L3, L4) and the image sensor (I). In one embodiment, at least one optical member (OM) may include a prism, and at least one of a surface facing at least one lens (L1, L2, L3, L4) (e.g., a first surface (F1)) or a surface facing the image sensor (I) (e.g., a second surface (F2)) may be curved or aspherical. For example, the at least one optical member (OM) may have positive refractive power or negative refractive power, thereby functioning as one lens in an optical system (e.g., a lens assembly (LA)). Accordingly, since at least one of a plurality of lenses may be implemented by at least one optical member (OM) in manufacturing an optical system or camera module (600) with the same performance, miniaturization of the optical system or camera module (600) may be facilitated. In one embodiment, by arranging at least one optical member (OM), the optical system or camera module (600) can have improved design freedom in implementing the optical path to the image sensor (I) and can be easily arranged in a narrow space while providing sufficient back focal length and / or good telephoto performance.

[0132] According to one embodiment, the lenses (L1, L2, L3, L4) may be sequentially arranged along the optical axis (O) from the object (S) side toward the image sensor (I). In the illustrated embodiment, an optical member (OM) may be configured to reflect light between the lenses (L1, L2, L3, L4) and the image sensor (I). For example, in the illustrated embodiment, the phrase “sequentially arranged from the object (S) side toward the image sensor (I)” may refer to the lenses (L1, L2, L3, L4) being sequentially arranged from the object (S) side toward the optical member (OM). In the embodiment described below, the ordinal numbers “first,” “second,” “third,” and “fourth” assigned to the lenses (L1, L2, L3, L4) 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, in the camera module (600) and / or lens assembly (LA), an aperture stop (or stop) may be disposed between the first lens (L1) and the fourth lens (L4). In one embodiment, the aperture stop may be disposed on a lens surface (e.g., an object-side surface or a sensor-side surface) of any one of the lenses (L1, L2, L3, L4). 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 fourth lens (L4) may be referred to as a “first lens on the image sensor (I) side” or a “lens disposed closest to the image sensor (I).”

[0133] According to one embodiment, in a structure where no optical member (OM) is arranged, the optical axis of an image sensor (I) (e.g., an imaging plane (img)) without a reference number can be aligned to coincide with the optical axis (O) of each lens (L1, L2, L3, L4). The imaging plane (img) can receive or detect light aligned or focused by, for example, the lenses (L1, L2, L3, L4). For example, the imaging plane (img) can be understood as an active area of ​​the image sensor (I). In one embodiment, when one optical member (OM) is arranged between the lenses (L1, L2, L3, L4) and the image sensor (I), the optical axis of the image sensor (I) can intersect the optical axis (O) at an interior (e.g., a reflective surface (F3)) of the optical member (OM). For example, light focused or guided by lenses (L1, L2, L3, L4) is incident through a first surface (F1) of the optical member (OM), and the optical member (OM) (e.g., a reflective surface (F3)) can refract or reflect the light incident through the first surface (F1) toward the image sensor (I). In one embodiment, it may be understood that the light refracted or reflected inside the optical member (OM) is emitted to the outside through a second surface (F2) of the optical member (OM). In one embodiment, the first surface (F1) may be understood as an incident surface of the optical member (OM), and / or the second surface (F2) may be understood as an exit surface of the optical member (OM).

[0134] According to one embodiment, as will be described with reference to FIG. 32, the optical member (OM) may include a plurality of reflective surfaces (e.g., reflective surfaces F3, F4 of FIG. 32 or 33). For example, light focused or guided by the lenses (L1, L2, L3, L4)(s) may be reflected at least twice by the optical member (OM) and then incident on the image sensor (I). In one embodiment, a plurality of prisms (e.g., prisms OM1, OM2, OM3 of FIG. 32 or 33) may be combined to implement one optical member (OM). However, the embodiment of the present disclosure is not limited thereto, and a single prism including a plurality of reflective surfaces (F3, F4) may be provided as one optical member (OM) disposed between the lenses (L1, L2, L3, L4)(s) and the image sensor (I).

[0135] According to one embodiment, at least one of the first surface (F1) or the second surface (F2) of the optical member (OM) is implemented as a curved or aspherical surface, so that the optical member (OM) can have positive or negative refractive power. For example, by having refractive power, the optical member (OM) can function as one of the lenses that control (or adjust) the aberration, angle of view, focal length, and / or resolution of the optical system or the lens assembly (LA). For example, the optical member (OM) can be miniaturized while improving the telephoto performance of the lens assembly (LA) or the camera module (600) by changing the path of light focused or guided through the lenses (L1, L2, L3, L4)(s), and / or by having refractive power, can contribute to reducing the number of lenses in implementing equivalent optical performance.

[0136] According to one embodiment, an optical component such as an infrared cut filter (F) may be disposed between at least one of the lenses (L1, L2, L3, L4) and the image sensor (I). The infrared cut filter (F) may be disposed between the fourth lens (L4) and the image sensor (I). In one embodiment, the infrared cut filter (F) may be disposed between the optical member (OM) 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 (600), 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).

[0137] According to one embodiment, among at least one lens (L1, L2, L3, L4), the first lens (L1) may be the first lens on the object (S) side or the lens disposed farthest from the image sensor (I), as mentioned above, and may include a convex object-side surface (S1). In one embodiment, the first lens (L1) may have positive refractive power. In one embodiment, since the first lens (L1) has positive refractive power, miniaturization of the entire optical system (e.g., lens assembly (LA)) may be facilitated, and since the first lens (L1) has positive refractive power and includes a convex object-side surface (S1), the f-number may be suppressed from increasing even when the telephoto magnification increases.

[0138] According to one embodiment, the second lens (L2) among at least one lens (L1, L2, L3, L4) may be positioned closest to the first lens (L1) and between the first lens (L1) and the optical member (OM) (or between the first lens (L1) and the image sensor (I)). In one embodiment, the second lens (L2) may have a meniscus shape that is convex toward the first lens (L1) or convex toward the object (S) side. For example, it may include a convex object-side surface (S3) and a concave sensor-side surface (S4). When the second lens (L2) has a meniscus shape that is convex toward the object (S) side, spherical aberration or astigmatism may be easily controlled even when the telephoto magnification of the camera module (600) and / or the lens assembly (LA) increases.

[0139] According to one embodiment, the third lens (L3) among at least one lens (L1, L2, L3, L4) may be disposed second closest to the first lens (L1) and between the first lens (L1) and the optical member (OM). For example, the third lens (L3) may be understood as being disposed between the second lens (L2) and the optical member (OM) (or 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 have negative refractive power and include a concave object-side surface (S6). When the sensor-side surface (S4) of the second lens (L2) is concave and the object-side surface (S6) of the third lens (L3) is concave, it can be easy to reduce spherical aberration or field curvature of the camera module (600) and / or lens assembly (LA).

[0140] According to one embodiment, the fourth lens (L4) may be a lens that is arranged closest to the optical member (OM) and / or the image sensor (I) among at least one lens (L1, L2, L3, L4). For example, the fourth lens (L4) may be a lens arranged between the first lens (L1) and the image sensor (I) (or between the third lens (L3) and the optical member (OM). In one embodiment, the fourth lens (L4) may have a positive refractive power. In one embodiment, when the fourth lens (L4) has a positive refractive power, the optical component (e.g., the optical member (OM) and / or the infrared cut filter (F)) arranged behind the fourth lens (L4) may be easily miniaturized.

[0141] In the illustrated embodiment, externally incident light is focused by the lenses (L1, L2, L3, L4)(s) and provided to the optical member (OM), and the optical member (OM) can refract or reflect the light focused by the lenses (L1, L2, L3, L4)(s) toward the image sensor (I). In one embodiment, the optical member (OM) can include a first surface (F1) (e.g., an incident surface) facing the lenses (L1, L2, L3, L4)(s) and a second surface (F2) (e.g., an exit surface) facing the image sensor (I). In one embodiment, an additional component, such as an infrared cut filter (F), can be disposed between the second surface (F2) and the image sensor (I). In one embodiment, at least one of the first surface (F1) and the second surface (F2) can be provided as a curved surface or an aspherical surface. For example, the optical member (OM) has refractive power and can align, focus, reflect and / or refract light incident through the lens (L1, L2, L3, L4)(s) and guide it to the image sensor (I).

[0142] In one embodiment, a processor (e.g., processor (120) of FIG. 1) or an image signal processor 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) 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) 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, 400 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 memory may store instructions that cause the electronic device to receive at least a portion of the light focused on the image sensor (I) and acquire an image of an object (S) based on the received light, and such instructions may be executed by the processor (s).

[0143] 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), optical member (OM)(s), or 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 sensor-side surface(s) of the lenses (L1, L2, L3, L4) may be omitted. The reference numbers for the lens surfaces omitted in the drawings will be easily understood through the [Tables] described below regarding the lens data of each embodiment. 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) 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.

[0144] 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) 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) 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.

[0145] According to one embodiment, the camera module (600) 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 focal length 'f' of the lens assembly (LA) and the maximum image height 'IH' of the image sensor (I). In one embodiment, the maximum image height 'IH' of the image sensor (I) may be half of the diagonal length of the imaging plane (img).

[0146]

[0147] According to one embodiment, when the condition of [Mathematical Formula 1] is satisfied, the camera module (600) and / or its lens assembly (LA) can be easily mounted on a miniaturized electronic device such as a smart phone (e.g., the electronic devices (200, 300, 400) of FIGS. 2 to 6) while providing telephoto performance. For example, when the calculated value of [Mathematical Formula 1] is less than approximately 2.5, the camera module (600) and / or its lens assembly (LA) can be miniaturized, but the focal length 'f' may become small, making it difficult to secure telephoto performance. On the other hand, when the calculated value of [Mathematical Formula 1] is greater than 20, the camera module (600) can provide further improved telephoto performance, but the lens front length or rear focal length may become large, making it difficult to mount on a miniaturized electronic device such as a smart phone. According to one embodiment, in the camera module (600) and / or the camera module of the embodiment(s) described below, the output value of [Mathematical Formula 1] may be approximately 3 or greater and approximately 15 or less.

[0148] According to one embodiment, the camera module (600) and / or its lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Expression 2]. [Mathematical Expression 2] may present conditions regarding, for example, the focal length 'f' of the lens assembly (LA) and the focal length 'f_p' of the optical member (OM) (e.g., a prism having refractive power). In the camera module (600) and / or its lens assembly (LA) of FIG. 8, the focal length 'f_p' of the optical member (OM) may be approximately 147.09 mm.

[0149]

[0150] According to one embodiment, when the camera module (600) and / or its lens assembly (LA) satisfies the conditions of [Mathematical Formula 2], the optical member (OM) may function as one of the lenses that controls (or adjusts) aberration, angle of view, focal length and / or resolution, and may be easily manufactured or assembled. For example, when the calculated value of [Mathematical Formula 2] is greater than approximately 20, the optical member (OM) may not have a substantial effect on the control (or adjustment) of aberration, angle of view, focal length and / or resolution, and when the calculated value of [Mathematical Formula 2] is less than approximately 0.2, the refractive power of the optical member (OM) increases, which may cause difficulties in the alignment of the lenses (L1, L2, L3, L4) - the optical member (OM) - the image sensor (I). According to one embodiment, in the camera module (600) and / or the camera module of the embodiment(s) described below, the calculated value of [Mathematical Formula 2] may be greater than or equal to about 0.25 and less than or equal to about 15. In the embodiment described below, for the sake of brevity of explanation, the focal length of the lens assembly (LA), the focal length of the optical member (OM), and / or the calculated value of [Mathematical Formula 2] may be rounded to the second decimal place.

[0151] According to one embodiment, the camera module (600) and / or its lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 3]. [Mathematical Formula 3] may, for example, present conditions regarding the field of view 'FOV' of the lens assembly (LA). In one embodiment, the unit of the field of view 'FOV' may be a degree.

[0152]

[0153] According to one embodiment, when the camera module (600) and / or its lens assembly (LA) satisfies the condition of [Mathematical Formula 3], it can be easily mounted on a miniaturized electronic device such as a smart phone (e.g., the electronic devices (200, 300, 400) of FIGS. 2 to 6) while providing telephoto performance. For example, when the calculated value of [Mathematical Formula 3] is greater than about 35, it may be difficult for the camera module (600) and / or its lens assembly (LA) to substantially provide telephoto performance, and when it is less than about 5, it may be difficult to be mounted on a miniaturized electronic device even if an optical member (OM) such as a prism is used. According to one embodiment, in the camera module (600) and / or the camera module of the embodiment(s) described below, the calculated value of [Mathematical Formula 3] may be greater than or equal to about 7 and less than or equal to about 33.

[0154] According to one embodiment, the camera module (600) and / or its lens assembly (LA) may satisfy the conditions presented through the following [Mathematical Formula 4]. [Mathematical Formula 4] may present conditions regarding, for example, the distance 'L_1-4' regarding the arrangement of the lenses (L1, L2, L3, L4) and the maximum height 'IH' of the image sensor (I). The distance 'L_1-4' regarding the arrangement of the lenses (L1, L2, L3, L4) may be, for example, a distance from the object-side surface (S1) of the first lens (L1) to the sensor-side surface (S9) of the fourth lens (L4), which may be a distance measured from the optical axis (O).

[0155]

[0156] According to one embodiment, when the camera module (600) and / or its lens assembly (LA) satisfies the condition of [Mathematical Formula 4], it can be easily mounted on a miniaturized electronic device such as a smart phone (e.g., electronic devices (200, 300, 400) of FIGS. 2 to 6) while providing optical performance (e.g., telephoto performance) that satisfies the design specifications. For example, when the calculated value of [Mathematical Formula 4] is greater than approximately 2, the sizes of the lenses (L1, L2, L3, L4) or the arrangement space of the lenses (L1, L2, L3, L4) may become large, making it difficult to mount on a miniaturized electronic device. On the other hand, when the calculated value of [Mathematical Formula 4] becomes less than approximately 1, the thickness of the lenses (L1, L2, L3, L4) becomes small, which may make it difficult to secure optical performance such as aberration control or resolution, and there may be difficulties in manufacturing or assembling the individual lenses (L1, L2, L3, L4). According to one embodiment, in the camera module (600) and / or the camera module of the embodiment(s) described below, the calculated value of [Mathematical Formula 4] may be approximately 1.2 or more and approximately 1.8 or less.

[0157] According to one embodiment, the camera module (600) and / or its lens assembly (LA) may have a focal length of approximately 13.2 mm, an F-number of approximately 3.1, and an angle of view of 21.45 degrees. The camera module (600) and / or its lens assembly (LA) may be combined with an image sensor (I) having a maximum image height of approximately 2.554 mm. In one embodiment, the camera module (600) and / or its lens assembly (LA) may satisfy at least some of the above-described condition(s) including [Mathematical Expression 1-4], and may be manufactured with the specifications exemplified in the following [Table 1]. In the following [Table 1], the symbol '*' attached to the number of the lens surface may indicate that the corresponding lens surface is aspherical. The lens surface corresponding to the aspherical surface will be more clearly understood through the [Tables] regarding aspherical coefficients described below. In [Table 1], the lens surface 'S11' is a surface whose refraction mode is set to 'Reflect', and may correspond to, for example, the reflective surface (F3) of the reflective member (OM). In [Table 1], the first surface (F1) of the reflective member (OM) may correspond to the lens surface 'S10', and the second surface (F2) of the reflective member (OM) may correspond to the lens surface 'S12'. In [Table 1] below, the aperture 'Stop' may be arranged between the second lens (L2) and the third lens (L3). In the embodiments described below, for example, the camera module (900) of FIG. 20 may provide the sensor-side surface (S8) of the fourth lens (L4) as an aperture, and in this case, it should be noted that the number of the lens surface corresponding to the first surface (F1) or the second surface (F2) of the reflective member (OM) may be assigned differently from that in [Table 1].

[0159] [Table 2], [Table 3], and [Table 4] below describe the aspherical coefficients of lenses (L1, L2, L3, L4) and / or optical elements (OM) (e.g., first surface (F1) and / or second surface (F2)), and the definition of aspherical surface is as follows [Mathematical Formula 5].

[0160]

[0161] 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”, or “O” depending on the notation.

[0195] FIG. 32 is a diagram illustrating a camera module (1200) and / or a lens assembly (LA) according to an embodiment of the present disclosure. FIG. 33 is a diagram illustrating a camera module (1300) and / or a lens assembly (LA) according to an embodiment of the present disclosure. FIG. 34 is a graph illustrating spherical aberration of the lens assembly (LA) of FIGS. 32 and 33 according to an embodiment of the present disclosure. FIG. 35 is a graph illustrating astigmatism of the lens assembly (LA) of FIGS. 32 and 33 according to an embodiment of the present disclosure. FIG. 36 is a graph illustrating a distortion rate of the lens assembly (LA) of FIGS. 32 and 33 according to an embodiment of the present disclosure.

[0196] Compared with the optical member of the camera module of the above-described embodiment, the optical member (OM) of FIGS. 32 and 33 may differ in that it is implemented by combining a plurality of prisms (OM1, OM2, OM3). For example, the optical member (OM) of FIGS. 32 and 33 may include a first prism (OM1) facing the lens (L1, L2, L3, L4)(e.g., the fourth lens (L4)), a second prism (OM2) facing the image sensor (I) (or the infrared cut filter (F)), and / or a dummy prism (OM3). The dummy prism (OM3) may be arranged, for example, between the first prism (OM1) and the second prism (OM2), thereby guiding light emitted from the first prism (OM1) to be incident on the second prism (OM2). In one embodiment, the first surface (F1) of the optical member (OM) can be implemented by, for example, a region of the surface of the first prism (OM1) that faces the fourth lens (L4). In one embodiment, the second surface (F2) of the optical member (OM) can be implemented by a region of the surface of the second prism (OM2) that faces the image sensor (I) (or the infrared cut filter (F)). In one embodiment, at least one of the first surface (F1) and the second surface (F2) is implemented as a curved surface or an aspherical surface, so that the optical member (OM) can have positive refractive power or negative refractive power.

[0197] According to one embodiment, the lens surface indicated as 'S10' may correspond to the first surface (F1) as an incident surface of the optical member (OM) and / or an incident surface of the first prism (OM1). In one embodiment, the lens surface indicated as 'S11' may be understood as, for example, a first reflective surface (F3) that reflects light incident on the first prism (OM1). In one embodiment, the lens surface indicated as 'S12' may exemplify a surface where the first prism (OM1) and the dummy prism (OM3) come into contact. For example, the lens surface 'S12' may be understood as an exit surface of the first prism (OM1) and an incident surface of the dummy prism (OM3). In one embodiment, the lens surface indicated as 'S13' may exemplify a surface where the dummy prism (OM3) and the second prism (OM2) come into contact. For example, the lens surface 'S13' can be understood as an exit surface of the dummy prism (OM3) and an incident surface of the second prism (OM2). In one embodiment, the lens surface indicated as 'S14' can be understood as, for example, a second reflection surface (F4) that reflects light incident on the second prism (OM2). In one embodiment, the lens surface indicated as 'S15' can correspond to the second surface (F2) as an exit surface of the optical member (OM) and / or an incident surface of the second prism (OM2).

[0198] According to one embodiment, the optical member (OM) can receive light through the first surface (F1), sequentially reflect the light using the first reflective surface (F3) and the second reflective surface (F4), and emit the light through the second surface (F2), and at least a portion of the light emitted from the second surface (F2) can be detected by the image sensor (I). At least one of the first surface (F1) and the second surface (F2) is implemented as a curved surface or an aspherical surface, so that the optical member (OM) can have positive refractive power or negative refractive power. When the camera module (1200) of FIG. 32 is described as having an optical member (OM) arranged between the lenses (L1, L2, L3, L4) and the image sensor (I), the camera module (1300) of FIG. 33 may differ in that the lenses (L1, L2, L3, L4) and the image sensor (I) are arranged on one side of the optical member (OM), and the manufacturing specifications of the lens assembly (LA) and the optical performance thereof may be similar.

[0199] The camera module (1200, 1300) and / or its lens assembly (LA) of FIGS. 32 and 33 may have a focal length of approximately 19.33 mm, an F-number of approximately 4.8, and an angle of view of approximately 15.5 degrees. In one embodiment, the camera module (1200) and / or its lens assembly (LA) may be combined with an image sensor (I) having a maximum image height of approximately 2.554 mm. In one embodiment, the camera module (1200) and / or its lens assembly (LA) may satisfy at least some of the above-described condition(s) including [Mathematical Formula 1-4].
