Description

Technical Field

[0001] The present disclosure relates to electronic devices, such as a lens assembly and an electronic device including the lens assembly. Background Art

[0002] Generally, electronic devices may refer to devices that perform predetermined functions according to programs set therein (e.g., electronic schedulers, portable multimedia copiers, mobile communication terminals, tablet personal computers (PCs), image / sound devices, desktop / laptop PCs, and / or vehicle navigation systems) and household appliances. The electronic devices mentioned above may output information stored therein as sound or images, for example. With the increasing degree of integration of electronic devices and the popularity of ultra-high-speed and large-capacity wireless communications, recently, a single electronic device such as a mobile communication terminal may have various functions. For example, in addition to communication functions, various functions such as entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions for mobile banking, etc., and / or schedule management or electronic wallet functions are also integrated in a single electronic device.

[0003] With the development of digital camera manufacturing technology, electronic devices equipped with miniaturized and lightweight camera modules have been commercialized. Since electronic devices (e.g., mobile communication terminals) that are basically carried at all times are equipped with camera modules, users can easily use various functions such as video calling and / or augmented reality and take pictures or videos.

[0004] In recent years, electronic devices including multiple cameras have been released. For example, the electronic device may include a camera module including, for example, a wide-angle camera and a telephoto camera. The electronic device may acquire a wide-angle image by photographing a wide-area scene around the electronic device using the wide-angle camera, or may acquire a telephoto image by photographing a scene corresponding to a position relatively far from the electronic device using the telephoto camera. In this way, by including multiple camera modules and / or lens assemblies, miniaturized electronic devices such as smart phones are entering the compact camera market, and are expected to replace high-performance cameras such as SLR cameras in the future.

[0005] The above information is presented as background information only to assist in understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above description might be applicable as prior art to the present disclosure. Summary of the invention

[0045] Throughout the drawings, like reference numerals will be understood to refer to like parts, components and / or structures. DETAILED DESCRIPTION

[0046] The following description is provided with reference to the accompanying drawings to assist in a comprehensive understanding of the various embodiments of the present disclosure as defined by the claims and their equivalents. The present disclosure includes various specific details to assist in understanding, but these should be considered as exemplary only. Therefore, it will be appreciated by those of ordinary skill in the art that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present disclosure. In addition, for clarity and brevity, descriptions of well-known functions and structures may be omitted.

[0047] The terms and words used in the following description and claims are not limited to the bibliographical meanings, but are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustrative purposes only and not for limiting the disclosure as defined by the appended claims and their equivalents.

[0048] It should be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component surface" includes reference to one or more of such surfaces.

[0049] As electronic devices become smaller and lighter, they can be more portable. In an environment where the display is enlarged so that a larger screen can be enjoyed even in a portable electronic device, the electronic device can be miniaturized and lightweight by reducing the thickness of the electronic device. In a miniaturized electronic device, it may be difficult to install a lens assembly with good optical performance. For example, the more the number of lenses or the larger the size, the easier it is to ensure the optical performance of the lens assembly. However, in a miniaturized electronic device, the design freedom of the arrangement of the lens or image sensor may be reduced.

[0050] Embodiments of the present disclosure are to at least solve the above-mentioned problems and / or disadvantages and provide at least the following advantages, and can provide a lens assembly with improved design freedom and / or an electronic device including the lens assembly.

[0051] Embodiments of the present disclosure can provide a lens assembly that can be easily disposed in a narrow space and / or an electronic device including the lens assembly.

[0052] The technical problems to be solved by the present disclosure are not limited to the technical problems described above, and other technical problems not described above can be clearly understood by ordinary technicians in the relevant field to which the present disclosure belongs from the following description.

According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components described above (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101.

For example, when the electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or adapted to be dedicated to a specific function. The auxiliary processor 123 may be implemented as a separate part from the main processor 121, or as part of the main processor 121.

[0055] When the main processor 121 is in an inactive (e.g., sleep) state, the auxiliary processor 123 (rather than the main processor 121) may control, for example, at least some of the functions or states related to at least one component among the components of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is in an active (e.g., running an application) state, the auxiliary processor 123 may control at least some of the functions or states related to at least one component among the components of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190) together with the main processor 121.

The display device 160 may include, for example, a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. According to an embodiment, the display module 160 may include a touch sensor adapted to detect a touch or a pressure sensor adapted to measure the strength of a force caused by a touch.

[0061] The audio module 170 can convert sound into an electrical signal, or vice versa.

The communication module 190 may include one or more communication processors that can operate independently from the processor 120 (e.g., an application processor (AP)) and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5th generation (5G) network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify or authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the subscriber identification module 196.

[0105] Figure 7 is a configuration diagram showing an optical path of a lens assembly in an electronic device according to an embodiment of the present disclosure.

[0106] Reference Figure 5 and Figure 6 According to an embodiment of the present disclosure, the electronic device 400 may include a device disposed on a surface (eg, Figure 3 In an embodiment, the camera window 385 may be a portion of the rear surface plate 380. In another embodiment, the camera window 385 may be coupled to the rear surface plate 380 via a decorative member 389, wherein the decorative member 389 may be exposed in the form of wrapping the periphery of the camera window 385 when viewed from the outside. According to another embodiment, the camera window 385 may include a plurality of transparent areas 387, and the electronic device 400 may receive external light through at least one of the transparent areas 387 or transmit light to the outside. For example, the electronic device 400 may include at least one lens assembly 500 (e.g., Figures 1 to 3385) and at least one light source (e.g., an infrared light source) arranged to correspond to other ones of the transparent areas 387. In an embodiment, the lens assembly 500 and / or the light source may receive external light or emit light to the outside of the electronic device 400 through any one of the transparent areas 387. In another embodiment, the electronic device 400 and / or the lens assembly 500 may further include a camera supporting member 381. The camera supporting member 381 may allow the lens assembly 500 and / or at least one of other lens assemblies adjacent to the lens assembly 500 (e.g., a wide-angle camera, an ultra-wide-angle camera, and / or a macro camera) to be disposed or fixed inside the rear surface plate 380 or the camera window 385. In another embodiment, the camera supporting member 381 may be substantially Figure 4 A portion of the first supporting member 311 and / or the second supporting member 360 .

[0107] According to another embodiment, the electronic device 400 may include a lens assembly 500 and / or at least one of a wide-angle camera, an ultra-wide-angle camera, a macro camera, a telephoto camera, or an infrared photodiode as a light receiving element, and may include a flash as a light source and / or a light emitting element (e.g., Figure 3 In another embodiment, the electronic device 400 may emit an infrared laser toward an object by using an infrared laser diode and an infrared photodiode, and may receive the infrared laser reflected by the object to detect the distance and / or depth of the object. In another embodiment, the electronic device 400 may photograph an object by using any one of the cameras or by using two or more of the cameras in combination, and, if necessary, may provide lighting toward the object by using a flash.

[0108] According to another embodiment, among the cameras, when compared with the telephoto camera (e.g., lens assembly 500), the wide-angle camera, the ultra-wide-angle camera, and / or the close-up camera may have a smaller length in the optical axis direction of the lens. For example, in a telephoto camera (e.g., lens assembly 500) having a relatively large focal length, the total track length of lenses 423a, 423b, and 423c is greater than the total track length of other cameras. The “total track length” may mean the distance from the object-side surface of the first lens on the object side to the imaging surface of the image sensor 411. As will be described later in another embodiment (e.g., Figure 8 In the lens assembly 600 in FIG. 1 , when another optical component(s) (e.g., a reflector and / or a prism) is disposed between the lens and the image sensor, the “total track 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. In an embodiment, even if the lens is disposed along the thickness of the electronic device 400 (e.g., Figure 4or Figure 6 The wide-angle camera, the ultra-wide-angle camera, and / or the close-up camera may also have a substantially small effect on the thickness of the electronic device 400 when arranged in a direction (e.g., the thickness measured in the Z-axis direction) of the electronic device 400. For example, the wide-angle camera, the ultra-wide-angle camera, and / or the close-up camera may be arranged in the electronic device 400 in a state where the direction of light incident from the outside into the electronic device 400 is substantially the same as the direction of the optical axis of the lens. In another embodiment, when compared with the wide-angle camera, the ultra-wide-angle camera, and / or the close-up camera, the lens assembly 500 (e.g., the telephoto camera) has a smaller field of view, but may be useful for photographing an object from a farther distance, and may include more lenses 421a, 421b, 423a, 423b, and 423c. For example, when the lenses 423a, 423b, and 423c of the lens assembly 500 are arranged in the thickness direction (e.g., the Z-axis direction) of the electronic device 400, the thickness of the electronic device 400 increases, or the lens assembly 500 may substantially protrude to the outside of the electronic device 400. In another embodiment of the present disclosure, the lens assembly 500 may include at least one refractive member 413 or 415 that reflects and / or refracts the incident light IL in different directions. When implementing the telephoto function, the lenses 423a, 423b, and 423c may be arranged to move forward and backward in the incident direction of the light or in the traveling direction of the reflected or refracted light, thereby suppressing or reducing the increase in the thickness of the electronic device 400.

[0109] Reference Figure 6 and Figure 7 , the folded camera (e.g., lens assembly 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, and 423c and / or a dummy member 423d). In another embodiment, at least one optical member may guide or focus the light RL1 reflected and / or refracted by the first refractive member 413 to the second refractive member 415, and may block the light RL1 reflected and / or refracted by the first refractive member 413 from being directly incident on the image sensor 411.

[0110] According to another embodiment, the first refractive member 413 may include, for example, a prism and / or a reflector. For example, the first refractive member 413 is configured as a prism including at least one reflector. For example, the first refractive member 413 is configured as a prism having at least one surface including a reflector. In another embodiment, the first refractive member 413 may reflect and / or refract the light IL incident in the first direction D1 in a second direction D2 intersecting the first direction D1. The first direction D1 may mean, for example, when photographing an object, the light IL passes from the outside through the first direction D1. Figure 5The first direction D1 refers to the direction in which any one of the transparent areas 387 of the electronic device 400 and / or the lens assembly 500 is incident. In another embodiment, the first direction D1 may mean a shooting direction, a direction toward an object, a direction in which the lens assembly 500 points, and / or a direction parallel thereto. In another embodiment, the first direction D1 may be parallel to the thickness direction and / or the Z-axis direction of the electronic device 400.

[0111] According to another embodiment, the second refractive member 415 may include, for example, a prism and / or a reflector. For example, the second refractive member 415 is configured as a prism including at least one reflector. For example, the second refractive member 415 is configured as a prism having at least one surface including a reflector. In another embodiment, the second refractive member 415 may reflect and / or refract the light RL1 reflected and / or refracted by the first refractive member 413 and incident in the second direction D2 in a third direction D3 intersecting the second direction D2. In another embodiment, the third direction D3 may be substantially perpendicular to the second direction D2. For example, the third direction D3 means a direction parallel to the Z-axis direction. However, the embodiments of the present disclosure are not limited thereto, and the third direction D3 may be a direction tilted relative to the second direction D2 or the XY plane according to the arrangement of the lens assembly 500 and / or the second refractive member 415 in the electronic device 400 and its specifications. In another embodiment, the third direction D3 may be substantially parallel to the first direction D1.

[0112] According to another embodiment, the image sensor 411 may be configured to detect light RL2 reflected and / or refracted by the second refractive member 415 and incident along the third direction D3. For example, light IL incident from the outside is detected by the image sensor 411 via the first refractive member 413 and the second refractive member 415, and the electronic device 400 and / or the lens assembly 500 may acquire an object image based on the signal and / or information detected by the image sensor 411. In another embodiment, the image sensor 411 may be arranged to be substantially parallel to the XY plane. For example, when the lens assembly 500 has an optical image stabilization function of a structure that shifts the image sensor 411, the image sensor 411 moves horizontally in a plane perpendicular to the first direction D1 and / or the third direction D3.

[0113] According to another embodiment, when performing the optical image stabilization function, the image sensor 411 can be shifted in the length direction of the electronic device 400 (e.g., the Y-axis direction) and / or the width direction of the electronic device 400 (e.g., the X-axis direction). For example, by arranging the image sensor 411 on a plane perpendicular to the first direction D1 and / or the third direction D3, it is possible to easily increase the size of the image sensor 411 and / or ensure space for the optical image stabilization operation in an electronic device having a smaller thickness (e.g., a thickness within about 10 mm). In another embodiment, when the lens assembly 500 is used as a telephoto camera, the quality of the captured image can be further improved by providing an optical image stabilization function. In another embodiment, when the image sensor 411 is enlarged, the performance of the lens assembly 500 can be further improved.

[0114] According to another embodiment, the lens assembly 500 may further include a lens system (e.g., a first lens group 421 including one or more lenses 421a and 421b) configured to guide and / or focus the light IL incident in the first direction D1 to the first refractive member 413. In another embodiment, the first lens group 421 and / or the first lens (e.g., the first lens 421a) disposed on the object side in the lens assembly 500 may have a positive refractive power. For example, by configuring the first lens 421a to focus and / or align the light IL incident from the outside to the first refractive member 413, the size of the optical system from the first lens 421a to the image sensor 411 is reduced. According to another embodiment, the first lens group 421 may further include an additional first lens 421b to focus and / or align the light incident from the outside.

[0115] According to another embodiment, the second lens group 423 may include a dummy member 423d and a light blocking member 425. The dummy member 423d may have, for example, a cylindrical shape disposed inside the lens assembly 500 and / or the electronic device 400 and extending along the second direction D2, and may transmit the light RL1 traveling along the second direction D2. In another embodiment, the dummy member 423d may be a lens having positive refractive power and / or negative refractive power. In another embodiment, the dummy member 423d may be a component integrated with any one of the second lenses 423a, 423b, and 423c and / or the second refractive member 415.

[0116] According to another embodiment, a light blocking member 425 may be provided and / or disposed on at least a portion of the outer peripheral surface of the dummy member 423d, and may absorb, scatter or reflect light. The light blocking member 425 may be provided by performing, for example, etching or black paint processing, and / or printing and / or depositing a reflective layer on at least a portion of the outer peripheral surface of the dummy member 423d. In another embodiment, some of the light reflected and / or refracted by the first refractive member 413 may be absorbed, scattered and / or reflected by the light blocking member 425. In another embodiment, the light blocking member 425 may substantially block the light reflected and / or refracted by the first refractive member 413 from being directly incident on the image sensor 411 without passing through the second lens group 423 and / or the second refractive member 415. For example, light that sequentially passes through the first direction D1, the second direction D2 and / or the third direction D3 in the lens assembly 500 (e.g., in Figure 7 The image sensor 411 can be made to receive light along paths indicated by “L1”, “RL1”, and “RL2”, and can substantially block light traveling along another path from being incident on the image sensor 411.

[0117] According to another embodiment, at least one of the second lenses 423a, 423b, and 423c may be moved forward and backward between the first refractive member 413 and the second refractive member 415 along an axis substantially the same as the second direction D2. For example, the electronic device 400 and / or the lens assembly 500 moves at least one of the second lenses 423a, 423b, and 423c forward and backward about an axis substantially the same as the second direction D2, thereby performing focal length adjustment and / or focus adjustment. A miniaturized electronic device such as a smart phone may have a thickness of about 10 mm, and in this case, the range in which the lens can be moved forward and backward in the thickness direction may be limited.

[0118] According to an embodiment, the second direction D2 may be aligned with the length direction (eg, Figure 4 Y-axis direction), width direction (for example, Figure 4 The second lens 423a, 423b, and 423c are substantially parallel to the X-axis direction of the second lens 423a and / or the XY plane, and the range of the forward and backward movement of at least one of the second lenses 423a, 423b, and 423c can be expanded compared to a general wide-angle camera that moves forward and backward in the Z-axis direction for focus adjustment. For example, since at least one of the second lenses 423a, 423b, and 423c moves forward and backward along an axis substantially the same as the second direction D2, the telephoto performance in the lens assembly 500 is improved, and thus the design freedom of ensuring a space for forward and backward movement for focal length adjustment and / or focus adjustment can be improved.

[0119] According to an embodiment, the electronic device 400 and / or the lens assembly 500 may further include an infrared blocking filter 419. In another embodiment, the infrared blocking filter 419 may suppress or substantially block light in the infrared or near-infrared band from being incident into the image sensor 411, and may be disposed at any position in the optical path between the first lens 421a and the image sensor 411. In another embodiment, by disposing the infrared blocking filter 419 at a position close to the image sensor 411 (e.g., between the image sensor 411 and the second refractive member 415), the infrared blocking filter 419 may be suppressed and / or prevented from being visually exposed to the outside. In another 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 blocking coating, in which case the infrared blocking filter 419 may be omitted. In another embodiment, the infrared blocking coating may be disposed on at least one of the image sensor side surface and the object side surface of the dummy member 423d and / or the second refractive member 415. Therefore, the image sensor 411 can detect light that has substantially passed through the infrared blocking filter 419 (or the infrared blocking coating). The refractive members 413 and 415 of the present disclosure can be selectively designed according to the structure of the lens assembly 500. For example, in an embodiment, the refractive member (e.g., Figure 6 The second refractive member 415 in the embodiment has a triangular prism shape. In another embodiment, the refractive member (eg, Figure 7 The second refractive member 415 in the embodiment may have a trapezoidal columnar shape. The shapes of the refractive members 413 and 415 are not limited to the structures shown in the present disclosure. For example, when the refractive members 413 and 415 reflect, refract, or transmit light, the refractive members 413 and 415 may have a shape other than a triangular prism shape or a trapezoidal columnar shape. In another embodiment, the type of the refractive members 413 and 415 to be provided may be determined in various ways. For example, the refractive members to be provided (e.g., Figure 6 The second refractive member 415 is a prism. For example, the refractive member to be set (eg, Figure 7 The second refractive member 415 is a reflector. For example, the refractive members 413 and 415 include a substantially transparent material. For example, the refractive members 413 and 415 are made of glass.

Fig.12 is a graph showing the distortion rate of the lens assembly 600 according to an embodiment of the present disclosure for light having a wavelength of 546.1000 (NM). In the following description, the lens assembly 600 has a structure including optical components R1 and R2 disposed between lenses L1, L2, L3 and L4 and the image sensor I. It should be noted that, depending on the number of times the light is reflected and / or refracted by the optical components R1 and R2, negative and positive may be reversed in the graphs of spherical aberration, astigmatism and / or distortion rate. When describing an embodiment of the present disclosure, optical data such as "total track length" or "focal length" may illustrate values ​​in a state where the optical components R1 and R2 are not included. For example, the first optical component R1 and / or the second optical component R2 may change the path of light travel by performing reflection and / or refraction, and may not substantially affect the optical performance (e.g., focal length, F number and / or field of view) of the lens assembly 600.

[0126] Reference Figure 8 and Fig. 9 , lens assembly 600 (eg, Figures 1 to 3The camera modules 180, 205, 212 or 213 and / or Figure 6 The lens assembly 500 may include at least two lenses L1, L2, L3 and L4, an image sensor I, and a plurality of optical members R1 and R2 disposed between the image sensor I and the at least two lenses (hereinafter referred to as "lenses L1, L2, L3 and L4"). Figure 8 In , "S2" may denote an object-side surface of the first lens L1 among lenses L1, L2, L3, and L4, and "S3" may denote a sensor-side surface of the first lens L1. When "sto" is added to a reference numeral indicating a lens surface, it may indicate that an aperture is implemented on the corresponding lens surface. For example, in Figure 8 In the lens assembly 600, the aperture is disposed on the object-side surface of the first lens L1. In an embodiment, "S4" may represent the object-side surface of the second lens L2 among the lenses L1, L2, L3, and L4, and "S5" may represent the sensor-side surface of the second lens L2. In another embodiment, "S6" may represent the object-side surface of the third lens L3 among the lenses L1, L2, L3, and L4, and "S7" may represent the sensor-side surface of the third lens L3. In another embodiment, "S8" may represent the object-side surface of the fourth lens L4 among the lenses L1, L2, L3, and L4, and "S9" may represent the sensor-side surface of the fourth lens L4. Tables 2, 5, 8, 11, and 14 regarding lens data will be discussed in detail below, but reference numerals of lens surfaces not shown in the drawings may be presented, and reference numerals "S10 to S15" regarding lens data in the tables may refer to surfaces of the first optical member R1 and / or the second optical member R2.

[0127] According to another embodiment, a plurality of optical components R1 and R2 may reflect, refract and / or guide light incident in one direction (e.g., in the direction of the second optical axis O2) or in another direction (e.g., in the direction of the third optical axis O3). For example, among the plurality of optical components R1 and R2, the first optical component R1 (e.g., the first reflective surface RF) reflects, refracts and / or guides light incident through lenses L1, L2, L3 and L4 to the second optical component R2. In another embodiment, the second optical component R2 may guide the light incident through the first optical component R1 to the image sensor I. According to another embodiment, the lens assembly 600 may further include an infrared blocking layer IFL. For example, the infrared blocking layer IFL is disposed on one of the incident surface F1 and the exit surface F2 of the second optical component R2. In an embodiment, the infrared blocking layer IFL may be disposed on one of the surfaces of the first optical component R1, or may be disposed on the surface of one of the lenses L1, L2, L3 and L4. According to another embodiment, as Fig.13As shown in the lens assembly 700 of FIG. 7 , in addition to the lenses L1, L2, L3, and L4 or the optical members R1 and R2, an infrared blocking filter IF may be provided. In another embodiment, when the infrared blocking filter IF is additionally provided, the infrared blocking layer IFL may not be provided on the lenses L1, L2, L3, and L4 and / or the optical members R1 and R2.

[0128] According to another embodiment, at least two (e.g., four) lenses L1, L2, L3, and L4 may be arranged in sequence along the direction of the first optical axis O1 from the object OB side. In another embodiment, the first optical axis O1 may be arranged to be aligned with the electronic device (e.g., Figures 1 to 6 The front surface of the electronic device 101, 200, 300 or 400) (for example, Figure 2 The first surface 210A in the embodiment and / or the rear surface (eg, Figure 3 The second surface 210B in the electronic device 400 is substantially parallel. For example, even if the thickness of the electronic device 400 is reduced, the design freedom of the number and arrangement of the lenses L1, L2, L3 and L4 is high. According to another embodiment, the electronic device 400 (for example, Figure 1 The processor 120 in the embodiment and / or the lens assembly 600 can move at least one of the lenses L1, L2, L3 and L4 forward and backward along the direction of the first optical axis O1. For example, by moving at least one of the lenses L1, L2, L3 and L4 along the direction of the first optical axis O1, focal length adjustment and / or focus adjustment is performed. In another embodiment, the electronic device 400 (e.g., Figure 1 The processor 120 in the embodiment and / or the lens assembly 600 may perform an optical image stabilization operation by moving at least one of the lenses L1, L2, L3, and L4 in a plane perpendicular to the first optical axis O1. From the description of “moving in a plane perpendicular to the first optical axis O1”, it can be understood that the lenses L1, L2, L3, and L4 move along at least two directions perpendicular to the first optical axis O1. The “at least two directions” may be, for example, directions perpendicular to each other.

[0129] According to another embodiment, the image sensor 1 may be configured to enable the lens assembly 600 and / or the electronic device 400 including the lens assembly 600 to acquire an image of the object by receiving light guided and / or focused by the lenses L1, L2, L3, and L4. For example, the second optical axis O2 is arranged to be aligned with the electronic device (e.g., Figures 2 to 6 The front surface of the electronic device 101, 200, 300 or 400) (for example, Figure 2 The first surface 210A in the embodiment and / or the rear surface (eg, Figure 3In another embodiment, the imaging surface img of the image sensor 1 may be arranged in a direction intersecting the first optical axis O1. For example, the imaging surface img of the image sensor 1 may form an acute angle and / or an obtuse angle with the first optical axis O1. In another embodiment, it can be understood from the description that “the imaging surface img may be arranged in a direction intersecting the first optical axis O1” that the imaging surface img is arranged relative to Figures 2 to 6 In another embodiment, since the image sensor 1 can be arranged in various directions relative to the alignment direction of the lenses L1, L2, L3 and L4, the design freedom of manufacturing the lens assembly 600 and / or the electronic device 400 including the lens assembly 600 can be improved.

[0130] According to another embodiment, the optical members R1 and R2 may reflect and / or refract the light incident thereon to change the traveling direction of the light. For example, by arranging the optical members R1 and R2 between the lenses L1, L2, L3, and L4 and the image sensor I, the design freedom of arranging the lenses L1, L2, L3, and L4 and the image sensor I may be improved. In the optical members R1 and R2, the first optical member R1 may be arranged between the lenses L1, L2, L3, and L4 and the image sensor I, and may receive the light incident through the lenses L1, L2, L3, and L4 in the direction of the first optical axis O1. In another embodiment, the first optical member R1 may reflect and / or refract the light incident through the lenses L1, L2, L3, and L4 in the direction of the first optical axis O1, thereby emitting light in the direction of the second optical axis O2 intersecting the first optical axis O1. In the illustrated embodiment, for ease of description, the second optical axis O2 is illustrated, but the embodiments of the present disclosure are not limited thereto. The second optical axis O2 may be defined differently according to an embodiment and / or a structure of the lens assembly 600 to be actually manufactured. In another embodiment, the first optical member R1 may include a reflective mirror and / or a prism.

[0131] It should be noted that, although the first optical member R1 and the second optical member R2 are illustrated as independent components in the disclosed embodiments, the embodiments of the present disclosure are not limited thereto. For example, the first optical member R1 and the second optical member R2 are configured integrally. In an embodiment, the exit surface of the first optical member R1 and the incident surface F1 of the second optical member R2 can be configured in a combined form. For example, an integrally configured optical member (not shown) includes a reflector and / or a prism. For example, an integrally configured optical member (not shown) is configured to include a prism including at least one reflector. For example, an integrally configured optical member (not shown) is configured to include a prism including at least one reflector. For example, an integrally configured optical member (not shown) is configured to include a reflector on one surface and a prism including at least a portion of another surface including a reflector.

[0132] According to another embodiment, among the plurality of optical members R1 and R2, the first optical member R1 may be disposed between the lenses L1, L2, L3, and L4 and the second optical member R2. In another embodiment, the first optical member R1 may reflect and / or refract light incident through the lenses L1, L2, L3, and L4 in the direction of the first optical axis O1, thereby emitting light in the direction of the second optical axis O2 substantially perpendicular to the first optical axis O1. According to another embodiment, the angle at which the second optical axis O2 is tilted relative to the first optical axis O1 may be implemented to be about 80 degrees or more and about 100 degrees or less.

[0133] According to another embodiment, among the plurality of optical members R1 and R2, the second optical member R2 may be disposed between the first optical member R1 and the image sensor I. For example, the second optical member R2 receives light incident through the first optical member R1 in the direction of the second optical axis O2, and may emit light to the image sensor I along the direction of the third optical axis O3 intersecting the second optical axis O2. In another embodiment, the third optical axis O3 may be disposed to be tilted at an angle other than perpendicular to the first optical axis O1. In another embodiment, the third optical axis O3 may be disposed to be tilted at an angle other than perpendicular to the second optical axis O2. In another embodiment, the third optical axis O3 may be disposed to be substantially parallel to the first optical axis O1 and tilted at an angle other than perpendicular to the second optical axis O2. In this way, the angles at which the optical axes O1, O2, and O3 are tilted relative to each other may be designed in various ways according to the embodiment. For example, the relative arrangement of the optical axes O1, O2, and O3 may vary according to the relative arrangement of the imaging surface img relative to the first optical axis O1, or may vary according to the structure of the lens assembly 600 and / or the electronic device 400 to be actually manufactured.

[0134] According to another embodiment, the second optical member R2 may include a prism. In an embodiment, the second optical member R2 may include a first surface (e.g., incident surface F1) facing the first optical member R1. For example, the incident surface F1 is perpendicular to the second optical axis O2. However, it should be noted that the embodiments of the present disclosure are not limited thereto. In another embodiment, the second optical member R2 may include a second surface (e.g., an exit surface F2) facing the image sensor I. For example, the exit surface F2 is connected to the incident surface F1 in an inclined state forming a first angle Ang-p1 relative to the incident surface F1. In another embodiment, the exit surface F2 may provide a total internal reflection environment for the incident light (e.g., light incident on the incident surface F1 along the direction of the second optical axis O2). For example, the exit surface F2 may reflect (or refract) the incident light by tilting at a predetermined angle relative to the second optical axis O2. The conditions of the inclination angle of the exit surface F2 relative to the second optical axis O2 will be discussed in detail with reference to equation 2 described below. As described above, the exit surface F2 may be at least partially used as a reflector inside the second optical member. In another embodiment, the second optical member R2 may include a second reflective surface F3 connecting the exit surface F2 and the incident surface F1 to each other. For example, the second reflective surface F3 is connected to the exit surface F2 in a state of forming a second angle Ang-p2, and may be connected to the incident surface F1 in a state of forming a third angle Ang-p3. In another embodiment, when the second reflective surface F3 is arranged to be substantially parallel to the second optical axis O2, the inclination angle of the exit surface F2 relative to the second optical axis O2 may be defined as a second angle Ang-p2.

[0135] According to another embodiment, the light reflected by the exit surface F2 inside the second optical member R2 can be emitted to the outside through the exit surface F2 after being reflected (or refracted) again by the second reflective surface F3. For example, when the incident angle is less than a predetermined angle, the exit surface F2 can provide a total internal reflection environment, and when the incident angle is greater than a predetermined angle, the exit surface F2 can transmit light. In this way, the light incident on the second optical member R2 can be reflected at least twice and emitted to the image sensor I through the exit surface F2. In another embodiment, when the lens assembly 600 has a structure including an infrared blocking layer IFL, the infrared blocking layer IFL can be disposed on at least a portion of the surface (e.g., incident surface F1 and / or exit surface F2) of the second optical member R2. The position and size of the infrared blocking layer IFL can be selected differently in consideration of the path of the light passing through the second optical member R2. In another embodiment, the infrared blocking layer IFL can be disposed on at least one of the incident surface F1 and the exit surface F2.

[0136] According to another embodiment, the electronic device 400 (eg, Figure 1The processor 120 in the embodiment of the present invention and / or the lens assembly 600 may perform optical image stabilization by rotating or tilting at least one of the optical components R1 and R2 (e.g., the first optical component R1) relative to the first optical axis O1. The "tilt operation" may include, for example, an operation of rotating the first optical component R1 around an arbitrary axis intersecting the first optical axis O1. The central axis of the tilt operation may be configured differently depending on the structure of the lens assembly 600 and / or the electronic device 400 to be actually manufactured.

[0137] According to another embodiment, the lens assembly 600 may further include another optical member (eg, Figure 6 For example, the direction in which the light is incident on the electronic device 400 and / or the lens assembly 600 is different from the direction of the first optical axis O1. As described above, when the conditions regarding Figure 8 When the components of the lens assembly 600 described above and / or to be described below are used, other components of the embodiments disclosed herein (for example, Figure 6 The first lens group 421, the first refractive member 413, the dummy member 423d and / or the light blocking member 425 in the embodiment may be used to implement further embodiments.

[0138] According to another embodiment, the lens assembly described above and / or to be described below (e.g., Figure 8 , Fig.13 , Fig.17 , Fig.21 and / or Fig.25 The lens assembly 600, 700, 800, 900, 1000 or 1100) in can satisfy the condition of equation 1 below.

[0139] Equation 1:

[0140]

[0141] "TTL" is the length from the object side surface S2 of the first lens (e.g., the first lens L1) on the object OB side among the lenses L1, L2, L3, and L4 to the sensor side surface S9 of the first lens (e.g., the fourth lens L4) on the image sensor I side, and can be understood as the "total track length". In the structure where the optical components R1 and R2 that change the light travel path between the lenses L1, L2, L3, and L4 and the image sensor I are not arranged, the "total track length" can be understood as the distance from the object side surface of the first lens on the object OB side to the imaging surface of the image sensor. In Equation 1, "f" can be the focal length (e.g., effective focal length) of the lens assembly 600. When the condition of Equation 1 is not satisfied, for example, when the value of Equation 1 is less than 0.1, the total track length becomes small, and thus it may be difficult to arrange the lenses L1, L2, L3, and L4 and to ensure good optical performance. When the value of Equation 1 is greater than 0.35, the total track length increases, and thus it may be difficult to install the lens assembly 600 in a miniaturized electronic device.

[0142] According to another embodiment, the lens assemblies 600 , 700 , 800 , 900 , 1000 , and 1100 described above and / or to be described below may satisfy the condition of Equation 2 below.

[0143] Equation 2:

[0144] 15≤Ang-min≤40

[0145] "Ang-min" is the minimum angle among the angles formed by two adjacent surfaces of the second optical member R2 (eg, the first angle Ang-p1, the second angle Ang-p2, and / or the third angle Ang-p3). Figure 8 implementation methods and / or Fig. 9 In an embodiment, the second angle Ang-p2 may be the "Ang-min" in equation 2. When the angle value of equation 2 is less than 15 degrees, the size of the second optical component R2 increases, which may make it difficult to miniaturize. In an embodiment, when the value of equation 2 is greater than 40 degrees, the reflective performance of the exit surface F2 inside the second optical component R2 may be reduced. For example, when the condition of equation 2 is met, the exit surface F2 inside the second optical component R2 totally reflects the light incident along the direction of the second optical axis O2. According to another embodiment, in the second optical component R2, when the third angle Ang-p3 is a right angle and the second angle Ang-p2 is "Ang-min", the second angle Ang-p3 may be implemented as an angle of about 25 degrees or more and about 35 degrees or less. According to another embodiment, the third angle Ang-p3 of the second optical component R2 may be implemented as an angle of about 75 degrees or more and about 105 degrees or less.

[0146] According to another embodiment, the lens assembly 600 , 700 , 800 , 900 , 1000 , or 1100 described above and / or to be described below may satisfy the condition of Equation 3 below.

[0147] Equation 3:

[0148]

[0149] Here, "f1" may be a focal length (e.g., effective focal length) of a first lens (e.g., first lens L1) on the object OB side, and "f2" may be a focal length of a second lens (e.g., second lens L2) on the object OB side. When the condition of Equation 3 is satisfied, aberrations in the lens assembly 600 may be easily corrected, and the size of the lens assembly 600 may be reduced. For example, when the value of Equation 3 is greater than -0.1, it may be difficult to correct chromatic aberration or spherical aberration. In another embodiment, when the value of Equation 3 is less than -2, the refractive power of the first lens L1 decreases, and thus the total track length may increase.

[0150] According to another embodiment, the lens assembly 600, 700, 800, 900, 1000 or 1100 described above and / or to be described below may satisfy the condition of the following equation 4 regarding the Abbe number Vd-1 of the first lens (e.g., first lens L1) on the object OB side.

[0151] Equation 4:

[0152] 25≤Vd-1≤95

[0153] When the value of Equation 4 is greater than 95, the possibility of damage to first lens L1 due to external impact or scratches may increase, and when the value of Equation 4 is less than 25, it may be difficult to correct chromatic aberration.

[0154] According to another embodiment, the lens assemblies 600 , 700 , 800 , 900 , 1000 , and 1100 described above and / or to be described below may satisfy the condition of Equation 5 below.

[0155] Equation 5:

[0156]

[0157] Here, "t-L1" may be the thickness of the first lens (e.g., first lens L1) on the object OB side, and "TTL" may be the length from the object-side surface S2 of the first lens L1 to the sensor-side surface S9 of the first lens (e.g., fourth lens L4) on the image sensor I side. When the value of Equation 5 is greater than 0.5, the thickness of the first lens L1 increases, and it is difficult to ensure the thickness of the remaining lenses L2, L3, and L4 or the intervals between the lenses L1, L2, L3, and L4. Therefore, it may be difficult to ensure good performance of the lens assembly 600. In another embodiment, when the value of Equation 5 is less than 0.1, the thickness of the first lens L1 decreases, and thus it may be difficult to ensure appropriate refractive power or to manufacture the first lens L1 into a designed shape.

[0158] According to another embodiment, the lens assemblies 600 , 700 , 800 , 900 , 1000 , and 1100 described above and / or to be described below may satisfy the following condition of Equation 6 regarding the field of view (FoV).

[0159] Equation 6:

[0160] 5≤FoV≤35

[0161] When the condition of Equation 6 is satisfied, the lens assembly 600 can be easily reduced in size while providing a space for arranging a plurality of optical components R1 and R2. For example, when the field of view is less than 5 degrees, the focal length of the lens assembly 600 becomes longer, which may make it difficult to reduce the size. In an embodiment, when the field of view is greater than 35 degrees, the intervals between the lenses L1, L2, L3, and L4 and the image sensor I are reduced, and thus it may be difficult to arrange the first optical component R1 and / or the second optical component R2.

[0162] As described in Table 1, the lens assemblies 600, 700, 800, 900, 1000, and 1100 of the embodiments described above and / or to be described below may satisfy the conditions presented by the equations described above. In Table 1, the minimum angle Ang-min in Equation 2 may be exemplified as the second angle Ang-p2 in the second optical member R2 of each embodiment.

[0163] Table 1

[0164]

[0165] According to another embodiment, the lens assembly 600 may have a focal length of approximately 9.73 mm, an F number of 3.475, a total track length of 2.6 mm, an image height of 2.28 mm, and / or a field of view (FoV) of 25.96 degrees. The total track length may be understood as, for example, the distance from the object-side surface S2 of the first lens L1 to the sensor-side surface S9 of the fourth lens L4, and the image height is the maximum distance from the optical axis O3 to the edge of the imaging surface img, and may be understood as, for example, half of the diagonal length of the imaging surface img. The lens assembly 600 may satisfy at least some of the conditions presented by the equations described above, and may be manufactured with the specifications illustrated in Table 2 below.

[0166] Table 2

[0167]

[0168]

[0169] In Table 2, the lens surface marked with "sto" can be used as an aperture, and the aspherical lens surface can be marked with the symbol "*". Like "S1" and / or "S10 to S18", the surface described in Table 2 but not shown in the drawings can be a cover window (e.g., Figure 5 or camera window 385 in 6), mechanical structures related to the arrangement design of lenses L1, L2, L3 and L4 or optical components R1 and R2, and / or surfaces of optical components R1 and R2. Although not directly shown in the drawings, the surfaces described in Table 2 are located, for example, on the path of external light reaching image sensor I, but may not substantially affect the optical performance of lens assembly 600. In the disclosed embodiment, the refraction mode in Table 2 illustrates whether the light beam travels by being refracted (refracted), reflected (reflected), or reflected by total internal reflection (TIR). Since the direction of travel of the light beam changes when it is reflected by optical components R1 and R2, Fig.10 and Fig.11 In the graph related to spherical aberration and / or astigmatism according to the number of reflections, “+” and “−” may be reversed.

[0170] In the following Tables 3 and 4, aspherical coefficients of the first lens L1, the second lens L2, the third lens L3, and the fourth lens L4 are described, and the definition of the aspherical surface can be calculated by the following Equation 7:

[0171] Equation 7:

[0172]

[0173] Here, "z" may mean a distance from the vertex of lens L1, L2, L3, or L4 in the direction of an optical axis (e.g., first optical axis O1), "y" may mean a distance in a direction perpendicular to first optical axis O1, "c" may mean a reciprocal of a radius of curvature at the vertex of lens L1, L2, L3, or L4, "K" may mean a cone constant, and "A", "B", "C", "D", "E", "F", "G", "H", and "J" may respectively mean aspheric coefficients. The radius of curvature (Radius) may represent, for example, a value indicating a degree of curvature at each point of a curved surface or curve.

The total track length can be understood as, for example, the distance from the object-side surface S2 of the first lens L1 to the sensor-side surface S9 of the fourth lens L4, and the image height is the maximum distance from the optical axis O3 to the edge of the imaging surface img, and can be understood as, for example, half of the diagonal length of the imaging surface img. The lens assembly 700 can be manufactured with the specifications illustrated in the following Table 5 while satisfying at least some of the conditions presented by the equations described above and the aspheric coefficients of Tables 6 and 7.

[0185] According to an embodiment, the lens assembly 700 may further include an infrared blocking filter IF disposed between the image sensor 1 and the second optical member R2. When the lens assembly 700 includes the infrared blocking filter IF disposed in addition to the lenses L1, L2, L3, and L4 or the optical members R1 and R2, the infrared blocking layer (e.g., Fig. 9 Infrared blocking layer IFL).
