[0031] Throughout the accompanying drawings, similar reference numerals may be assigned to similar parts, constructions, and / or structures. Detailed Implementation

[0032] As electronic devices become smaller and lighter, they become more portable and easier to use. In an environment where displays are getting larger, allowing users to enjoy larger screens even on portable electronic devices, reducing the thickness of the device can make it smaller and lighter. However, mounting a camera module with good optical performance in a miniaturized electronic device can present challenges. For example, while it might be easier to ensure good optical performance in a camera module with a greater number of lenses and / or larger lens sizes, the design freedom for arranging lenses or image sensors may be reduced in miniaturized electronic devices. Therefore, multiple camera modules (such as telephoto cameras, wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras) that provide good optical performance across different field of view can be mounted in a single electronic device. Telephoto cameras with smaller field of view (or longer focal lengths) than other camera modules can be easily mounted in miniaturized electronic devices by including optical components that alter the light path (e.g., prisms or mirrors). For example, aligning lenses or image sensors is easier when optical components such as mirrors or prisms are incorporated. However, when additional optical components are added, the number of reflections or refractions in the path of incident light to the image sensor may increase, resulting in an increase in the amount of light reaching the image sensor via paths other than the designed path. Light incident via non-designed paths, or the resulting degradation of image quality, can be referred to as "stray light" or "flare".

[0033] The embodiments of this disclosure are intended to at least address the aforementioned problems and / or disadvantages and provide at least the following advantages, and may provide a camera module including an optical component that causes light guided to an image sensor to be reflected or refracted at least once and / or an electronic device including the camera module.

[0034] Embodiments of this disclosure may provide a camera module and / or an electronic device including the camera module that promotes miniaturization while providing telephoto performance by increasing the design freedom of the optical path.

[0035] Embodiments of this disclosure may provide a camera module and / or an electronic device including the camera module that includes optical components and is capable of suppressing stray light or flare caused by reflection or refraction of light directed to an image sensor.

[0036] The technical objectives to be achieved in this disclosure are not limited to those described above, and other technical objectives not mentioned will be clearly understood by those skilled in the art from the following description.

[0037] The following description with reference to the accompanying drawings provides an understanding of various exemplary embodiments of the present disclosure, including the claims and corresponding content.

Therefore, those skilled in the art will understand that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present disclosure.

Figure 1 In network environment 100, electronic device 101 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with at least one of electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, electronic device 101 can communicate with electronic device 104 via server 108. According to an embodiment, electronic device 101 may include a processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, user identification module (SIM) 196, or antenna module 197. In some embodiments, at least one of the above components (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments, some of the components described above (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single component (e.g., display module 160).

[0041] Processor 120 may run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 in conjunction with processor 120, and may perform various data processing or calculations. According to embodiments, as at least part of the data processing or calculations, processor 120 may store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the resulting data in non-volatile memory 134. According to embodiments, processor 120 may include a main processor 121 (e.g., central processing unit (CPU) or application processor (AP)) or a coprocessor 123 (e.g., graphics processing unit (GPU), neural processing unit (NPU), image signal processor (ISP), sensor central processor, or communication processor (CP)) that is operationally independent of or combined with main processor 121. For example, when electronic device 101 includes a main processor 121 and a coprocessor 123, the coprocessor 123 may be adapted to consume less power than the main processor 121, or to be dedicated to a specific function. The coprocessor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.

[0042] When the main processor 121 is inactive (e.g., in sleep) state, the coprocessor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the coprocessor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190).

According to embodiments, the coprocessor 123 (e.g., a neural processing unit) may include hardware architecture dedicated to artificial intelligence model processing. Artificial intelligence models can be generated through machine learning. For example, such learning can be performed via an electronic device 101 that executes the artificial intelligence model or via a separate server (e.g., server 108).

[0046] The sound output module 155 can output sound signals to the outside of the electronic device 101. The sound output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver may be implemented separately from the speaker or as part of the speaker.

[0047] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user).

According to an embodiment, display module 160 may include a touch sensor adapted to detect touch or a pressure sensor adapted to measure the intensity of the force caused by touch.

[0048] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input module 150, or output sound via the sound output module 155 or via headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0049] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

[0056] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules may communicate with an external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, 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, 5G network, 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 may be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 may use user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify or verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199).

[0057] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas.

According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0058] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190. Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of antenna module 197.

[0059] According to an embodiment, antenna module 197 can form a millimeter-wave antenna module. According to an embodiment, the millimeter-wave antenna module may include a printed circuit board, an RFIC, and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on a second surface (e.g., the top surface or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals in the specified high-frequency band.

[0060] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via inter-peripheral communication schemes (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0061] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some of the operations that would run in electronic device 101 can run in one or more of external electronic devices 102, 104, or 108. For example, if electronic device 101 is to automatically perform a function or service or should perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service.

Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

[0092] Figure 6 This illustrates an electronic device 400 according to an embodiment of the present disclosure (e.g., Figures 1 to 5 The electronic devices 101, 200 and 300) along Figure 3 A cross-sectional view of a portion of A-A' in the diagram. Figure 7 This is a structural diagram showing the optical path of a camera module 500 in an electronic device 400 according to an embodiment of the present disclosure.

[0093] Reference Figure 3 and Figure 6 Electronic device 400 according to embodiments of the present disclosure (e.g., Figures 1 to 5Electronic devices 101, 200, and 300 may include those disposed on one of their surfaces (e.g., Figure 3 Cover plate 385 on the second surface 210B of the back panel 380. In an embodiment, cover plate 385 may be part of the back panel 380. In an embodiment, cover plate 385 may be attached to the back panel 380 by means of a decorative member 389, and the decorative member 389 may be exposed in the form of surrounding the periphery of cover plate 385 when viewed from the outside. According to an embodiment, cover plate 385 may provide a plurality of transparent areas, and electronic device 400 may receive external light or emit light to the outside through at least one of the transparent areas. For example, electronic device 400 may include: at least one camera module 500 (e.g., Figures 1 to 3 The camera modules 500, 205, 212, and 213 are configured to correspond to at least some of the transparent areas, and at least one light source (e.g., a flash or IR light source) is configured to correspond to other transparent areas within the transparent areas. In an embodiment, the camera module 500 and / or the light source may receive external light or emit light to the outside of the electronic device 400. In an embodiment, the electronic device 400 and / or the camera module 500 may further include a camera support member 381. The camera support member 381 may mount or fix at least one of the camera module 500 and / or another adjacent camera module (e.g., a wide-angle camera, an ultra-wide-angle camera, and / or a macro camera) to the inside of the rear panel 380 and / or the cover plate 385. In an embodiment, the camera support member 381 may be substantially... Figure 4 A portion of the first support member 311 and / or the second support member 360.

[0094] According to an embodiment, the electronic device 400 may include at least one of a wide-angle camera, an ultra-wide-angle camera, a macro camera, a telephoto camera, or an IR photodiode as a camera module 500 and / or a light receiving element, and may include a flash (e.g., Figure 3 The electronic device 400 uses a flash (213) or an IR laser diode as the light source and / or light-emitting element. In an embodiment, the electronic device 400 can detect the distance and / or depth of an object by radiating IR laser light onto the object and receiving the IR laser light reflected by the object using an IR laser diode and an IR photodiode. In an embodiment, the electronic device 400 can capture the object by combining one or more cameras and illuminate the object as needed using a flash.

[0095] According to embodiments, in cameras, wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras may have shorter lengths in the optical axis direction of the lens compared to telephoto cameras (e.g., camera module 500). For example, a telephoto camera (e.g., camera module 500) with a relatively small field of view and a relatively long focal length may have a longer total lens length than other cameras (e.g., wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras). The term "total lens length" can be the distance from the object-side surface of the first object-side lens to the imaging surface of the image sensor 411. As described later in the embodiments ( Figure 8 In the camera module 600 and / or its optical system, when other optical components (e.g., mirrors and / or prisms) are disposed between the lens and the image sensor, the "total lens length" can be the distance from the object-side surface of the first object-side lens to the sensor-side surface of the first sensor-side lens. In embodiments, even when the lens is along the thickness direction of the electronics 400 (e.g., in...), the "total lens length" can be the distance from the object-side surface of the first object-side lens to the sensor-side surface of the first sensor-side lens. Figures 2 to 6 When the thickness (measured along the Z-axis) is arranged, wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras will not significantly affect the thickness of the electronic device 400. For example, wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras can be arranged in the electronic device 400 such that the direction of light incident on the electronic device 400 from the outside is substantially the same as the optical axis direction of the lens. In embodiments, camera module 500 (e.g., telephoto camera) may have a small field of view compared to wide-angle cameras, ultra-wide-angle cameras, and / or macro cameras, but can be used to capture objects at longer distances. In embodiments of this disclosure, camera module 500 may include at least one optical component R that reflects and / or refracts incident light IL in different directions. By including at least one optical component R, camera module 500 can easily achieve telephoto functionality while suppressing an increase in the thickness of the electronic device 400.

[0096] Reference Figure 6 and Figure 7The folding camera (e.g., camera module 500) may include a lens assembly 421 (e.g., lenses 421a and 421b), at least one optical element R (e.g., a refractive or reflective element), and / or an image sensor 411. In an embodiment, at least one optical element R may reflect or refract light (e.g., incident light IL) focused or guided by the lens assembly 421 at least once and guide it to the image sensor 411. In an embodiment, the optical element R may include, for example, a prism and / or a mirror. For example, the optical element R may be formed as a prism including at least one mirror. In an embodiment, the optical element R may reflect and / or refract light IL incident in a first direction D1 to a second direction D2 intersecting the first direction D1. The first direction D1 may represent, for example, the direction in which light IL is incident from the outside onto the electronic device 400 and / or camera module 500 when capturing an object. In an embodiment, the first direction D1 may refer to the capture direction, the object direction, the orientation direction of the camera module 500, and / or directions parallel to them. In an embodiment, the first direction D1 may be parallel to the thickness direction and / or the Z-axis direction of the electronic device 400.

[0097] According to an embodiment, light RL1, reflected or refracted within the optical component R and traveling in the second direction D2, can be reflected and / or refracted by another region within the optical component R and travel in a third direction D3 intersecting the second direction D2. In an embodiment, the third direction D3 may be substantially perpendicular to the second direction D2. For example, the third direction D3 may represent a direction parallel to the Z-axis direction. However, embodiments of this disclosure are not limited thereto, and depending on the arrangement and specifications of the camera module 500 and / or the optical component R in the electronic device 400, the third direction D3 may be a direction inclined relative to the second direction D2 and / or the XY plane. In an embodiment, the third direction D3 may be substantially parallel to the first direction D1.

[0098] According to an embodiment, the image sensor 411 may be configured to detect light RL2 traveling along a third direction D3 after being reflected and / or refracted at least once inside the optical component R. For example, light IL incident from the outside may be detected by the image sensor 411 after being reflected or refracted at least once (e.g., twice in the illustrated embodiment) inside the optical component R, and the electronic device 400, Figure 1 The processor 120 and / or camera module 500 can acquire images of objects based on signals and / or information detected by the image sensor 411. In embodiments, the image sensor 411 may be arranged substantially parallel to the XY plane. For example, when the camera module 500 has image stabilization with a structure that shifts the image sensor 411, the image sensor 411 may move horizontally in a plane substantially perpendicular to the first direction D1 and / or the third direction D3.

[0099] According to an embodiment, during optical image stabilization, the image sensor 411 can be displaced in the length direction (e.g., the Y-axis direction) and / or width direction (e.g., the X-axis direction) of the electronic device 400. For example, when the image sensor 411 is positioned in a plane substantially perpendicular to the first direction D1 and / or the third direction D3, the size of the image sensor 411 can be easily increased and / or space can be ensured for image stabilization operations in electronic devices with a small thickness (e.g., about 10 mm or less). In an embodiment, when the camera module 500 is used as a telephoto camera, the quality of the captured image can be further enhanced by combining image stabilization operations. In an embodiment, increasing the size of the image sensor 411 can further improve the performance of the camera module 500.

[0100] According to an embodiment, the lens assembly 421 can guide and / or focus light IL incident in a first direction D1 onto the optical component R. In an embodiment, the lens assembly 421 and / or the first lens (e.g., the first lens 421a) disposed in the object side of the camera module 500 can have positive refractive power. For example, since the first lens 421a is configured to focus externally incident light IL onto and / or align it with the optical component R, the optical system from the first lens 421a to the image sensor 411 can be miniaturized. In an embodiment, the lens assembly 421 may also include an additional lens (e.g., a second lens 421b) for focusing and / or aligning externally incident light.

[0101] According to an embodiment, at least one of the first lens 421a and / or the second lens 421b may be positioned in the direction of light incident (e.g., Figure 6 The lens moves forward and backward in the first direction (D1). For example, the electronic device 400 and / or camera module 500 can perform focus adjustment and / or focus adjustment by moving at least one of the first lens 421a and / or the second lens 421b forward and backward. In an embodiment, this can be achieved by moving the lens forward and / or focusing along the direction of light incidence indicated by "RL2" (e.g., Figure 6 The third-party D3 in the image sensor 411 moves forward and backward to perform focus adjustment and / or focus adjustment.

[0102] According to embodiments, the electronic device 400 and / or camera module 500 may further include an IR cutoff filter 419. In embodiments, the IR cutoff filter 419 can suppress or substantially block IR and / or near-IR wavelength light incident on the image sensor 411, and can be positioned at any location in the optical path between the first lens 421a and the image sensor 411. In embodiments, since the IR cutoff filter 419 is positioned close to the image sensor 411 (e.g., between the image sensor 411 and the optical component R), it can suppress and / or prevent the IR cutoff filter 419 from being visually exposed to the outside. In embodiments, the optical component R may include an IR cutoff coating, in which case the IR cutoff filter 419 can be omitted. As a result, the image sensor 411 can substantially detect light that has passed through the IR cutoff filter 419 (or the IR cutoff coating).

[0103] The optical component R according to embodiments of the present disclosure can be selectively designed according to the structure of the camera module 500. For example, in one embodiment, the optical component R may have a prism shape. In another embodiment, the optical component R may have a trapezoidal prism shape. The shape of the optical component R is not limited to the structures shown in this disclosure. For example, the optical component R may have a structure other than a prism or trapezoidal prism (e.g., a parallelogram prism shape) as long as it reflects, refracts, or transmits light. In embodiments, various types of optical components R can be arranged. For example, the optical component R may be configured as a prism. For example, the optical component R may be configured as at least one mirror. In another embodiment, the optical component R may comprise a substantially transparent material. For example, the optical component R may be made of glass.

[0104] According to embodiments, the optical component R can be implemented by combining multiple prisms or mirrors. For example, an optical component R in the shape of a parallelogram prism or trapezoidal prism can be implemented by combining triangular prisms and / or quadrilateral prisms. Thus, when implementing the optical component R according to embodiments of the present disclosure, it should be noted that various optical elements such as reflective components, prisms, and / or mirrors can be selectively combined, and the shape or number of optical elements is not limited to the embodiments shown in the figures. In embodiments, when the optical component R is implemented by combining multiple optical elements, a light-shielding structure can be easily provided. A "light-shielding structure" can refer to a structure that suppresses, reduces, or blocks light incident on the optical component R through an undesigned path or light traveling along an undesigned path inside the optical component R to reach the image sensor 411. The construction of the optical component R will be more readily understood from the embodiments described later. In embodiments of the present disclosure, the term "optical system" can be understood to include lens assemblies and / or optical components configured to focus or guide external light to the image sensor.

The horizontal axis represents the longitudinal spherical aberration coefficient, and the vertical axis represents the normalized distance from the optical axis O, showing the variation of longitudinal spherical aberration with respect to the wavelength of light. Longitudinal spherical aberration is shown for, for example, light with wavelengths of 656.3000 (NM), 587.6000 (NM), 546.1000 (NM), 486.1000 (NM), and 435.8000 (NM). Figure 11 This is a graph showing the astigmatism curve of a camera module 600 according to an embodiment of the present disclosure for light with a wavelength of 546.1000 nm. "X" represents the sagittal plane, and "Y" represents the tangential plane (or meridional plane). Figure 12 This is a graph showing the distortion of a camera module 600 according to an embodiment of the present disclosure for light with a wavelength of 546.1000 nm. In the following description, it should be noted that the camera module 600 includes the aforementioned optical component 601 disposed between lenses L1, L2, L3, and L4 and image sensor I (e.g., Figure 6 and Figure 7 The structure of the optical component R in the diagram. It should be noted that the signs of the curves showing spherical aberration, astigmatism, and / or distortion are negative / positive, which may be reversed depending on the number of times the light is reflected and / or refracted by the optical component R or 601.

[0107] Reference Figures 8 to 12A camera module 600 (and / or its optical system) according to embodiments of the present disclosure may include a lens assembly LA (e.g., at least two lenses L1, L2, L3, and L4), an optical component 601 including a reflective surface RS, and / or an image sensor I configured to detect light reflected by the reflective surface RS. In the illustrated embodiment, as an example, the lens assembly LA may be shown as including four lenses L1, L2, L3, and L4. The camera module 600 and / or its optical system can suppress image quality degradation caused by stray light or flare while achieving telephoto performance by satisfying the following conditions regarding the arrangement of the lenses L1, L2, L3, and L4, their arrangement relative to the image sensor I, and / or the relative dimensions of the surfaces through which light passes in the optical component 601 (e.g., the incident surface IS and the exit surface ES) or the reflective surface RS. In embodiments, at least some of the conditions described below for the camera module 600 and / or its optical system may provide a suitable arrangement or implementation, for example, a light-shielding structure (e.g., Figure 21 The environment of the light-shielding member 915 (or 915a and 915b). Here, "light-shielding structure" can refer to a structure that blocks light from traveling along an undesigned path or absorbs light traveling along an undesigned path. In embodiments, the light-shielding structure or light-shielding member can be implemented in the form of a layer formed by processes such as printing, spraying, coating, deposition and / or plating, or it can be implemented in the form of an attachment such as a film or sheet.

[0108] According to embodiments, at least two lenses L1, L2, L3, and L4 may be sequentially aligned along the optical axis O, and in the illustrated embodiment, the camera module 600 and / or lens assembly may include four lenses L1, L2, L3, and L4. The optical axis O is, for example, a virtual axis passing through the vertices of the object-side surfaces and / or image-side surfaces of the lenses L1, L2, L3, and L4, and may be used as a reference for setting or arranging the lenses L1, L2, L3, and L4. In embodiments, even if the lenses L1, L2, L3, and L4 are rotated about the optical axis O, the optical characteristics or performance of the camera module 600 will not change. In embodiments, the lenses L1, L2, L3, and L4 may focus or guide externally incident light to the optical component 601 and / or the image sensor I. For example, light focused by the lenses L1, L2, L3, and L4 may be incident on the optical component 601. Optical component 601 (e.g., reflective surface RS) can, for example, reflect light focused by lenses L1, L2, L3, and L4 at least once and guide it to image sensor I. The relative position or angle of image sensor I with respect to lenses L1, L2, L3, and L4 can be achieved differently by the arrangement of optical component 601 or reflective surface RS. For example, when optical component 601 is provided, camera module 600 can be miniaturized while maintaining good telephoto performance.

[0109] According to an embodiment, among lenses L1, L2, L3, and L4, the lens furthest from the image sensor I or optical component 601 may be referred to as the first lens L1. For example, when external light is incident, the lens through which the external light first passes can be defined as the first lens L1. In an embodiment, the first lens L1 may be referred to as the "first lens disposed on the object side". When the camera module 600 includes multiple lenses L1, L2, L3, and L4, ordinal numbers such as "first", "second", "third", "fourth", ... "nth" may be used for each lens L1, L2, L3, and L4 according to the order in which external light is transmitted and incident on the image sensor I. In an embodiment, the lens among at least two lenses L1, L2, L3, and L4 that is closest to the image sensor I or optical component 601 may be referred to as the "nth lens". Figure 8 and Figure 9 The nth lens in the camera module 600 can be understood as the fourth lens L4.

[0110] According to an embodiment, the first lens L1 may have positive refractive power. When the first lens (e.g., the first lens L1) positioned on the object side has positive refractive power, the overall beam size can be reduced, thereby facilitating miniaturization of the optical system or camera module 600. In an embodiment, the first lens L1 may provide an environment that ensures chromatic aberration correction and good focal length by having a refractive index or dispersion value (e.g., Abbe number) within a specified range. This will be described again below.

[0111] According to an embodiment, similar to the first lens L1, the nth lens (e.g., the fourth lens L4), positioned closest to the image sensor I or optical component 601, can facilitate ease of manufacture and aberration correction by having a refractive index within a specified range. For example, since the fourth lens L4 has a refractive index of about 1.6 or greater and about 1.7 or less, it can be manufactured using materials that facilitate achieving the designed shape (e.g., plastic) and provides an environment conducive to controlling aberrations such as field curvature and / or astigmatism. The construction of the nth lens will be described again below.

[0112] According to an embodiment, at least one lens with negative refractive power may be disposed between the first lens L1 and the nth lens (e.g., the fourth lens L4). For example, in Figure 9 or Figure 13 In camera module 600 or 700 or lens assembly LA, the third lens L3 may have negative refractive power. Figure 17The second lens L2 in the camera module 800 or lens assembly LA may have negative refractive power. As described later, a lens with negative refractive power positioned between the first lens L1 and the nth lens (e.g., the fourth lens L4) can facilitate chromatic aberration correction or refractive power arrangement of lenses L1, L2, L3, and L4 by having a dispersion value within a specified range. In an embodiment, when multiple lenses with negative refractive power are positioned between the first lens L1 and the nth lens, the lens positioned closest to the nth lens and having negative refractive power can be configured to satisfy conditions related to the following dispersion values.

[0113] According to an embodiment, at least one of the lenses L1, L2, L3, and L4 of the lens assembly LA can perform an autofocus function by reciprocating along a first linear motion direction LM1. "First linear motion direction LM1" may refer to a direction substantially parallel to or substantially coincident with the optical axis O. In an embodiment, at least one of the lenses L1, L2, L3, and L4 of the lens assembly LA can perform an image stabilization function by horizontal movement (e.g., vibration) along at least two directions (e.g., a second linear motion direction LM2) on a plane intersecting the optical axis O. "Plane intersecting the optical axis O" may refer to a plane substantially perpendicular to the optical axis O. In an embodiment, essentially the entire lens assembly LA can perform autofocus and / or image stabilization functions by reciprocating motion.

[0114] According to embodiments, autofocus and / or image stabilization can be achieved through the reciprocating motion of image sensor I. For example, image sensor I can perform autofocus by reciprocating along a third linear motion direction LM3, and perform image stabilization by horizontal motion (e.g., vibration) in at least two directions (e.g., a fourth linear motion direction LM4) on a plane intersecting the second optical axis OS. "Second optical axis OS" can refer to the path of light incident along the optical axis O of lenses L1, L2, L3, and L4 after being reflected by the reflective surface RS and reaching image sensor I. The third linear motion direction LM3 can be substantially parallel to or substantially coincide with the second optical axis OS. Although the angle between the reflective surface RS and the incident surface IS may vary, in a configuration where the incident surface IS and the reflective surface RS form a substantially 45-degree angle, the second optical axis OS can be configured to be substantially perpendicular to the optical axis O of lenses L1, L2, L3, and L4.

[0115] According to embodiments, image stabilization and / or object tracking functions can be achieved through the movement, rotation, and / or tilting operations of the optical component 601. For example, image stabilization and / or object tracking functions can be achieved when the optical component 601 performs horizontal movement (e.g., vibration) on a specified plane (e.g., a plane substantially parallel to the imaging surface img of the image sensor I) or performs rotation and / or tilting operations RM around a specified point (or rotation axis RA). In embodiments, the rotation and / or tilting operation RM of the optical component 601 can be understood as an operation that changes the orientation or tilt angle of the incident surface IS, the reflecting surface RS, and / or the exiting surface ES relative to the image sensor I (e.g., the imaging surface img).

[0116] According to an embodiment, the optical component 601 may include an incident surface IS configured to at least partially face the lens assembly LA, an exit surface ES configured to at least partially face the image sensor I, and / or a reflective surface RS configured to be tilted relative to the incident surface IS or the exit surface ES. For example, light focused by the lens assembly LA (e.g., Figure 7 The incident light IL can be incident on the optical component 601 through the incident surface IS, and the light incident on the optical component 601 can be reflected at least once by the reflecting surface RS (e.g., Figure 6 or Figure 7 The light RL1, traveling along the second direction D2, is then provided to the image sensor I through the exit surface ES. Although not shown, an additional reflective member (e.g., a mirror or prism) may be provided between the optical member 601 and the image sensor I within the range of satisfying the following conditions, thereby achieving [the desired effect]. Figure 6 or Figure 7 The optical path is similar to the optical path.

[0117] According to an embodiment, optical component 601 can be implemented by a combination of first optical component 611 and second optical component 613. However, this distinction between the various parts of optical component 601 is for ease of description, and the embodiments of this disclosure are not limited thereto. For example, first optical component 611 and second optical component 613 can be implemented as a single body (or a single piece), wherein the portion provided with reflective surface RS can be defined as first optical component 611 having a prism shape. In an embodiment, the following light-shielding components (e.g., Figure 21 or Figure 22The light-shielding members 915 (or 915a and 915b) may be disposed on at least a portion of the surface of the optical member 601 (e.g., an area that does not interfere with light reaching the image sensor I). In embodiments, when the first optical member 611 and the second optical member 613 are configured to be combined facing each other, at least a portion of the boundary region between the first optical member 611 and the second optical member 613 may be configured as a region in which the light-shielding members 915a and 915b are disposed. For example, in the configuration of the first optical member 611 and the second optical member 613, the arrangement of the light-shielding members 915a and 915b is easier, thereby suppressing or substantially preventing stray light or flare.

[0118] According to embodiments, the first optical component 611 (and / or the second optical component 613) may provide an incident surface IS and / or a reflecting surface RS, and an exiting surface ES may be disposed on the second optical component 613. In embodiments, the incident surface IS or the exiting surface ES can typically be implemented in a polygonal shape (e.g., a rectangle). However, embodiments of this disclosure are not limited thereto, and the incident surface IS or the exiting surface ES may be implemented as a circle or an ellipse. In embodiments, the corner formed by the contact between the two different surfaces of the first optical component 611 and / or the second optical component 613 may be processed into a curved shape or an inclined surface shape. For example, when the corner is processed into a curved or inclined surface shape in a structure in which the two different surfaces of the first optical component 611 are configured to form acute, obtuse, and / or right angles, damage or breakage of the first optical component 611 can be suppressed even when subjected to interference from other structures or exposed to impact. Such curved or inclined surface processing may be similar in the second optical component 613.

[0119] According to embodiments, the curved or inclined surface processing of corner portions in optical components 601 (e.g., first optical component 611 and / or second optical component 613) may be one of the causes of stray light or flare. In embodiments, optical component 601 may satisfy at least some of the following conditions, which may facilitate the light-shielding structure (e.g., Figure 21 or Figure 22The implementation of light-shielding members 915a and 915b in the optical component 601. In an embodiment, the optical component 601 may include light-shielding members 915a and 915b on at least a portion of its outer surface, in the remaining area of ​​the incident surface IS excluding the area through which external light (e.g., light focused by the lens assembly LA) is transmitted, and / or in the remaining area of ​​the exit surface ES excluding the area through which light to be guided to the image sensor IS is transmitted. The light-shielding members 915a and 915b may, for example, absorb light traveling along an unintended path or substantially block light incident on the image sensor I. These light-shielding members 915a and 915b may be implemented in the form of layers formed by processes such as printing, spraying, coating, deposition, and / or plating, or in the form of attachments such as films or sheets. Thus, by including light-shielding members 915a and 915b, the optical component 601 can suppress stray light or flare while including corner portions processed as curved surfaces (or inclined surfaces).

[0120] According to an embodiment, the camera module 600 and / or its optical system may further include an IR cutoff filter F. The IR cutoff filter F can, for example, suppress or block light of wavelengths (e.g., IR light) that are not visible to the user's naked eye but are sensed by the photosensitive material or image sensor I from incident on the image sensor I. The IR cutoff filter F may be disposed between the fourth lens L4 and the image sensor I, or between the optical component 601 and the image sensor I. Depending on the purpose of the camera module 600 (e.g., a depth camera), the IR cutoff filter F may be replaced by a bandpass filter that transmits IR light and suppresses or blocks visible light.

[0121] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by the following [Equation 1].

[0122] [Formula 1] 0.1 ≤ TL / OTTL ≤ 0.6 Here, "TL" can be the distance from the vertex of the object surface S2 of the lens furthest from optical component 601 and / or image sensor I (e.g., the first lens L1) to the vertex of the image surface S9 of the lens closest to optical component 601 (e.g., the fourth lens L4 as the nth lens). The "vertex" of the object or image surface of lenses L1, L2, L3, and L4 can refer to the point where the optical axis O intersects with the lens surface. For example, "TL" in [Equation 1] can represent the distance measured along the optical axis O from the object surface S2 of the first lens L1 to the image surface S9 of the fourth lens L4. In [Equation 1], "OTTL" can represent the distance traveled by light incident along the optical axis O from the object surface S2 of the first lens L1 to the image sensor I. For example, "OTTL" can be the sum of a first distance OTTL1 measured along the optical axis O from the vertex of the object surface S2 of the first lens L1 to the reflecting surface RS, and a second distance OTTL2 measured from the point RP where the reflecting surface RS intersects with the optical axis O to the image sensor I. In an embodiment, the second distance OTTL2 can be the distance along the second optical axis OS from the reflecting surface RS to the image sensor I.

[0123] According to an embodiment, when the conditions of [Equation 1] are met, the camera module 600 and / or its optical system can provide telephoto performance while being easily mounted in an electronic device with a thickness of approximately 10 mm or less. In an embodiment, when the value calculated by [Equation 1] is less than 0.1, it may be difficult to ensure good image quality in telephoto mode. When it is greater than 0.6, it may be difficult to mount the camera module 600 and / or its optical system in an electronic device with a thickness less than the specified specification (e.g., approximately 10 mm or less). For example, [Equation 1] may present conditions that allow the camera module 600 and / or its optical system to be miniaturized while providing telephoto performance. In an embodiment, for the camera module 600 and / or its optical system, the value calculated by [Equation 1] may be approximately 0.15 or greater and approximately 0.25 or less.

[0124] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by [Equation 2].

[0125] [Equation 2] 1.25≤Pin / Pout≤10 Here, "Pin" can be the maximum length of the surface (e.g., incident surface IS) on which light focused by lenses L1, L2, L3, and L4 is incident in the optical component 601. For example, when the incident surface IS is rectangular, "Pin" can be the length of the long side of the incident surface IS. In an embodiment, when the incident surface IS is elliptical, "Pin" can be the length of the major axis of the incident surface IS. In an embodiment, "Pin" can be the length of the incident surface IS measured substantially parallel to the direction along which the second distance OTTL2 is measured (e.g., the second optical axis OS). For example, the long side when the incident surface IS of the optical component 601 is rectangular or the major axis when the incident surface IS is elliptical can be set substantially parallel to the second optical axis OS. In [Equation 2], "Pout" can be the maximum length of the surface of the optical component 601 that is set to face the image sensor I (e.g., exit surface ES), and can be the length measured substantially parallel to the direction along which the first distance OTTL1 is measured. In an embodiment, when the optical component 601 includes a first outer surface 615 parallel to the incident surface IS, "Pout" can be understood as the interval between the incident surface IS and the first outer surface 615. In an embodiment, for the camera module 600 and / or its optical system, the value calculated by [Equation 2] can be about 1.3 or greater and about 2.5 or less.

[0126] According to the embodiment, the shape of the optical component 601 is not limited to the illustrated embodiment. For example, the light-transmitting component of the optical component 601 may be removed. Figure 8 or Figure 9 The optical component 601 is guided to a portion outside the area of ​​the image sensor I, or a third or fourth optical component (not shown) may be further disposed on the surface (not shown) of the optical component 601. When the optical component 601 is manufactured to be compatible with... Figure 8 or Figure 9 When the shapes shown are different, "Pin" in [Equation 2] can be understood as the maximum length of the optical component 601 measured in a plane perpendicular to the optical axis O or the maximum length of the optical component 601 measured along a direction parallel to the second optical axis OS. In the embodiment, "Pin" can be understood as the maximum length of the optical component 601 measured along the direction perpendicular to the light traveling through the exit surface ES or the maximum length of the optical component 601 measured along the direction perpendicular to the imaging surface img of the image sensor I. In the embodiment, "Pin" can be understood as the maximum length of the optical component 601 measured parallel to the direction along which the second distance OTTL2 is measured. When the optical component 601 is manufactured as... Figure 8 or Figure 9When the shapes shown are different, "Pout" in [Equation 2] can be understood as the maximum length of the optical component 601 measured on a plane perpendicular to the second optical axis OS, or the maximum length of the optical component 601 measured along a direction parallel to the optical axis OS. In the embodiment, "Pout" can be understood as the maximum length of the optical component 601 measured along the direction along which light perpendicularly passes through the incident surface IS travels toward the reflecting surface RS, or the maximum length of the optical component 601 measured along a direction parallel to the imaging surface img of the image sensor I. In the embodiment, "Pout" can be understood as the maximum length of the optical component 601 measured along a direction parallel to the direction along which the first distance OTTL1 is measured.

[0127] In an embodiment, the camera module 600 and / or its optical system can provide an environment conducive to the arrangement of light-shielding members 915a and 915b in a miniaturized structure by satisfying the conditions presented by [Equation 2]. For example, when the value calculated by [Equation 2] is greater than 10, the size of the incident surface IS or the aforementioned second distance OTTL2 may increase, which may make miniaturization of the camera module 600 and / or its optical system difficult. In an embodiment, when the value calculated by [Equation 2] is less than 1.25, a large portion of the incident surface IS and / or the exit surface ES of the optical member 601 can be used as an optical path. For example, when the value calculated by [Equation 2] is less than 1.25, it may be difficult to arrange the light-shielding members 915a and 915b. Thus, when the conditions of [Equation 2] are satisfied, the camera module 600 and / or its optical system can be miniaturized and stray light effectively suppressed while including the optical member 601. As will be referred to Figure 21 and Figure 22 As described, when light that has been reflected or refracted at least once inside the optical component 601 travels along an undesigned path, the light-shielding components 915a and 915b disposed in the optical component 601 can absorb or substantially block the light traveling along the undesigned path toward the image sensor I.

[0128] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by [Equation 3].

[0129] [Formula 3] 50≤Vd1≤95 Here, "Vd1" represents the dispersion value of the lens (e.g., the first lens L1) furthest from optical component 601. By satisfying the conditions of [Equation 3], camera module 600, its optical system, and / or the first lens L1 can be easily manufactured and facilitate chromatic aberration correction. For example, when the dispersion value Vd1 of the first lens L1 is less than 50, it may be difficult to ensure good optical performance. When it is greater than 95, the first lens L1 may become soft, making it difficult to manufacture in the designed shape and easy to deform. In embodiments, the dispersion value (e.g., Abbe number) of the first lens L1 in camera module 600 and / or its optical system may be about 60 or less.

[0130] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by [Equation 4].

[0131] [Formula 4] 10≤Vdneg≤45 Here, "Vdneg" can represent the setting between the first lens L1 and the nth lens (e.g., Figure 8 or Figure 9 The dispersion value of the lens with negative refractive power between the first lens L1 and the fourth lens L4. In an embodiment, when there are multiple lenses with negative refractive power disposed between the first lens L1 and the fourth lens L4, the dispersion value of at least one lens among the multiple lenses with negative refractive power that is closest to the fourth lens L4 satisfies the condition of [Equation 4]. In an embodiment, [Equation 4] can present conditions that facilitate the arrangement and design of lenses L1, L2, L3, and L4 while achieving good optical performance. For example, when the lens with negative refractive power that is closest to the fourth lens L4 satisfies the condition of [Equation 4], chromatic aberration correction and refractive power arrangement can be facilitated in the camera module 600 and / or its optical system. In an embodiment, Figure 9 or Figure 13 The second lens L2 in the embodiment can satisfy the condition of [Equation 4], Figure 17 The third lens L3 in the embodiment can satisfy the conditions of [Equation 4]. In the embodiment, the dispersion value (e.g., Abbe number) of the lens satisfying the conditions of [Equation 4] in the camera module 600 and / or its optical system can be about 25 or greater and about 40 or less.

[0132] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by [Equation 5].

[0133] [Formula 5] 5≤FOV≤35 [Equation 5] presents the conditions for miniaturizing the camera module 600 and / or its optical system while achieving telephoto performance. "FOV" may represent the field of view of the camera module 600 and / or its optical system. For example, when the field of view of the camera module 600 and / or its optical system is less than 5 degrees, the focal length may increase, making miniaturization of the camera module 600 and its optical system difficult. When it is greater than 35 degrees, the focal length may decrease, making it difficult to ensure the second distance OTTL2 required to satisfy the conditions of [Equation 1]. In embodiments, the field of view of the camera module 600 and / or its optical system may be about 20 degrees or greater and about 30 degrees or less.

[0134] According to an embodiment, the camera module 600 and / or its optical system may satisfy the conditions presented by the following [Equation 6] and [Equation 7].

[0135] [Formula 6] 1.45≤nd1≤1.6 [Formula 7] 1.6≤ndn≤1.7 Here, "nd1" can represent the refractive index of the first lens L1, which is furthest from the optical component 601 and / or the image sensor I, and "ndn" can represent the refractive index of the nth lens, which is closest to the optical component 601 and / or the image sensor I (e.g., ...). Figure 8 and / or Figure 9 The refractive index of the fourth lens L4 in the embodiment. In an embodiment, when the first lens L1 has a refractive index greater than 1.6 and is made of plastic, the dispersion value may be less than 35, making chromatic aberration correction difficult.

[0156] Figure 21 This illustrates a camera module 900 according to an embodiment of the present disclosure (e.g., Figure 5 Camera component 307 or Figures 6 to 9 , Figure 13 and / or Figure 17 Illustrations of camera modules 500, 600, 700 and 800. Figure 22 This illustrates an embodiment according to the present disclosure. Figure 21 A diagram illustrating the structure for blocking stray light in the camera module 900.

[0157] Reference Figure 21 and Figure 22Stray light SL1 and SL2 or flares may occur in the path of light incident from the outside onto the camera module 900, reflected or refracted by lens assemblies LA or L1, L2, L3, and L4 and / or optical components 901 or 911 and 913. Stray light or flares may become more frequent in structures with increased reflection or refraction rates in optical component 901, and / or when the corners of optical component 901 are machined into curved or inclined surface shapes. In the design and arrangement of lens assemblies LA and / or optical components 901, it is almost impossible to predict all directions of external light incident on the camera module 900, as well as the directions of reflection and / or refraction within optical component 901. For example, when an optical system is implemented by combining multiple lenses L1, L2, L3, and L4 with optical component 901, the occurrence of stray light SL1 and SL2 or flares may be unavoidable. Figure 21 and Figure 22 In the detailed description of the embodiments, refer together with Figures 1 to 7 Electronic devices 101, 200, 300 and 400 and / or Figure 8 and Figure 9 The camera module 600.

[0158] According to embodiments of this disclosure, the camera module 900 and / or its optical system can suppress stray light SL1 and SL2 from reaching the image sensor I by including light-shielding members 915 or 915a and 915b. For example, the light-shielding member 915 (e.g., the first light-shielding member 915a) can be disposed on the incident surface of the optical member 901 (e.g., Figure 8 The incident surface IS is at least a portion of the area through which light focused by lenses L1, L2, L3, and L4 transmits. For example, a first light-shielding member 915a may be disposed on at least a portion of the periphery of the area of ​​the incident surface IS facing lenses L1, L2, L3, and L4, or on the edge of the incident surface. Light-shielding members 915a and 915b may be implemented by layers formed, for example, by processes such as printing, spraying, coating, deposition, and / or plating, and / or by attachments such as films or sheets. In an embodiment, a light-shielding member 915 (e.g., a second light-shielding member 915b) may be disposed on the exit surface of the optical member 901 (e.g., Figure 8The light-shielding member 915b is disposed on at least a portion of the remaining area of ​​the emitting surface 901, excluding the area through which light to be guided to the image sensor I is transmitted. For example, the second light-shielding member 915b may be disposed on at least a portion of the area of ​​the emitting surface 901 corresponding to the image sensor I or on the edge of the emitting surface 901. In an embodiment, the light-shielding members 915a and 915b may be disposed on substantially the entire outer surface of the optical member 901, excluding the area through which light incident through lenses L1, L2, L3, and L4 is transmitted or the area through which light to be guided to the image sensor I is transmitted. In an embodiment, when the optical member 901 is a structure combining the first optical member 911 and the second optical member 913, the light-shielding members 915a and 915b may also be disposed at the boundary between the first optical member 911 and the second optical member 913.

[0159] According to an embodiment, when stray light SL1 and SL2 reach the light-shielding members 915a and 915b, the stray light SL1 and SL2 can be substantially absorbed by the light-shielding members 915a and 915b, or may not travel further in the current direction of travel. In an embodiment, when the light-shielding members 915a and 915b are disposed on the exit surface ES, stray light SL1 and SL2 traveling toward the image sensor I can be substantially absorbed or blocked by the light-shielding members 915a and 915b. For example, the camera module 900 and / or its optical system according to embodiments of the present disclosure can suppress the degradation of the quality of the captured image by suppressing stray light incident on the image sensor.

[0161] As described above, the camera module according to embodiments of this disclosure (e.g., Figure 5 Camera component 307, Figures 6 to 9 , Figure 13 , Figure 17 , Figure 21 and / or Figure 22 Camera modules 500, 600, 700, 800, and 900), optical systems, and / or electronic devices including them (e.g., Figures 1 to 6 The electronic devices 101, 200, 300, and 400 can be easily miniaturized while providing good telephoto performance. In embodiments, when at least some of the above conditions are met, the camera module, optical system, and / or the electronic devices including them can suppress stray light (e.g., Figure 21 or Figure 22 Image quality degradation caused by stray light SL1 and SL2 in the image. For example, a light-shielding component (e.g., Figure 21 or Figure 22 The light-shielding components 915a and 915b suppress or substantially block light from reaching the image sensor on non-designed paths.
