Description

Telephoto camera capable of close-up shooting and electronic device including the same

[0001] Various embodiments of the present disclosure relate to electronic devices, for example, to a telephoto camera capable of close-up photography and an electronic device including the same.

[0002] Lens assemblies, such as cameras capable of taking photos or videos, have been widely used, and recently, digital cameras and video cameras equipped with solid-state image sensors such as CCD (charge coupled device) or CMOS (complementary metal-oxide semiconductor) have become commonplace. Lens assemblies employing solid-state image sensors (CCD or CMOS) are replacing film-type lens assemblies because they facilitate the storage, replication, and / or transfer of images between electronic devices compared to film-type lens assemblies.

[0003] Recently, multiple lens assemblies, such as macro cameras, telephoto cameras, and / or wide-angle cameras, have been mounted on a single electronic device to improve the quality of captured images and to impart various visual effects to the images. For example, high-quality images can be obtained by acquiring images of a subject through multiple cameras with different optical characteristics and synthesizing them. As high-quality images can be obtained by mounting multiple lens assemblies (e.g., cameras), electronic devices such as mobile communication terminals or smartphones can replace electronic devices specialized in shooting functions, such as digital cameras.

[0004] In miniaturized and / or lightweight electronic devices, it may be difficult to improve the performance of a camera or a lens assembly placed therein. For example, the internal space of a miniaturized and / or lightweight electronic device may be narrow, making it difficult for the camera to perform telephoto functions within the limited space.

[0005] The information described above may be provided as background art for the purpose of aiding understanding of the disclosure of this disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art in relation to the disclosure of this disclosure.

[0006] According to one embodiment of the present disclosure, a telephoto camera capable of close-up shooting is disclosed. The telephoto camera may include an image sensor; a lens assembly comprising at least two lens groups arranged sequentially along an optical axis direction from the subject side toward the upper side of the image sensor; and a lens barrel surrounding the lens assembly. The lens assembly may include: a first lens group comprising at least three lenses positioned at the first of the at least two lens groups on the subject side, comprising a first-1 lens positioned at the first of the subject side and having positive power, a first-2 lens positioned at the second of the subject side, and a first-3 lens positioned at the furthest position on the subject side, having positive power and having a convex image side surface; and a second lens group comprising at least three lenses positioned at the second of the at least two lens groups on the subject side, comprising a second-1 lens positioned at the first of the subject side, a second-2 lens positioned at the second of the subject side, and a second-3 lens positioned at the furthest position on the subject side and having negative power. Additionally, focusing may be possible by moving the lenses within the internal space of the lens barrel. Additionally, the following [Equation 1] may be satisfied.

According to one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as a first network (198) or a second network (199), may be selected from the plurality of antennas, for example, by a communication module (190).

The lens assembly (210) may collect light emitted from a subject that is the target of image capture. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, F-number (Fno), or optical zoom), or at least one lens assembly may have one or more lens properties different from the lens properties of other lens assemblies. The lens assemblies (210) may include, for example, wide-angle lenses or telephoto lenses.

[0112] A flash (220) may emit light used to enhance light emitted or reflected from a subject. According to one embodiment, the flash (220) may include one or more light-emitting diodes (e.g., RGB (red-green-blue) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. An image sensor (230) may acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through a lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) may include, for example, one image sensor selected from image sensors with different properties such as an RGB sensor, a BW (black and white) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same properties, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0113] The image stabilizer (240) may move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operational characteristics of the image sensor (230) (e.g., adjusting read-out timing, etc.) in response to the movement of the camera module (180) or the electronic device (101) containing it. This allows for compensating for at least some of the negative effects caused by the movement on the image being captured. According to one embodiment, the image stabilizer (240) may detect such movement of the camera module (180) or the electronic device (101) using a gyroscope sensor (not shown) or an accelerometer sensor (not shown) placed inside or outside the camera module (180).

The memory (250) may temporarily store at least a portion of the image acquired through the image sensor (230) for the next image processing operation. For example, if image acquisition by the shutter is delayed or multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and the corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Subsequently, when a specified condition is satisfied (e.g., user input or system command), at least a portion of the original image stored in the memory (250) may be acquired and processed by, for example, an image signal processor (260). According to one embodiment, the memory (250) may be configured as at least a portion of the memory (230) or as a separate memory that operates independently thereof.

The image processed by the image signal processor (260) may be stored back in memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) is at least part of the processor (120). It may be configured as a separate processor that operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (260) as is or after additional image processing by the processor (220).

[0137] The electronic device (101) disclosed in FIGS. 3 and 4 has a bar-type or plate-type appearance, but is not limited thereto. For example, the illustrated electronic device may be part of a rollable electronic device or a foldable electronic device. "Rollable electronic device" may mean an electronic device in which the display (210) is capable of bending deformation so that at least a portion can be wound or rolled or stored inside the housing (201). Depending on the user's needs, the rollable electronic device may be used to expand the screen display area by unfolding the display or by exposing a larger area of ​​the display to the outside. "Foldable electronic device" may mean an electronic device that can be folded so that two different areas of the display face each other or in opposite directions. Generally, in a portable state, the display of a foldable electronic device is folded so that two different regions face each other or in opposite directions, and in an actual usage state, the user can unfold the display so that the two different regions form a substantially flat shape. In some embodiments, the electronic device (101) according to various embodiments of the present disclosure may be interpreted to include not only portable electronic devices such as smartphones, but also various other electronic devices such as laptop computers or home appliances.

[0138] The electronic device (101) of the present disclosure may include a camera module (1100; 1200; 1300; 1400; 1500; 1600; 1700; 1800; 1900) described below.

[0139] FIG. 5 is a diagram showing the acquisition of images of objects through various cameras included in the electronic device of the present disclosure.

[0140] An electronic device (e.g., the electronic device (101) of FIGS. 1 to 4) may include various cameras (207a, 207b) as shown in FIG. 5. For example, the electronic device (101) may include a standard camera (or wide-angle camera) (207a) and a telephoto camera (207b). Focal length may refer to the distance from the center of the lens (e.g., the principal point) to the image sensor (IS), and each camera may have a different focal length.

[0141] According to one embodiment, a lens having a standard focal length (e.g., 35mm) is called a standard (or general) lens, and if the focal length is shorter than this, it is called a wide-angle lens, or if the focal length is longer, it is called a telephoto lens. And cameras containing these lenses, respectively, can be called a standard camera, a wide-angle camera, and a telephoto camera. A wide-angle lens (207a) with a relatively short focal length (e.g., f1) may have a relatively wide angle of view compared to a telephoto lens with a relatively long focal length (e.g., f2) (FOV1 > FOV2). Because the wide-angle lens has a relatively wide angle of view, it may be easy to acquire a wide range of images from a relatively close distance, and because the telephoto lens has a relatively narrow angle of view, it may be easy to acquire a narrow range of images from a relatively far distance.

[0142] Since wide-angle lenses have a relatively shorter focal length compared to telephoto lenses (r2 > r1), they allow for shooting at a close distance to the subject and facilitate shooting from various angles. Here, the focal length may refer to the distance from the camera's second principal point to the image plane of the image sensor (IS). Here, the second principal point may refer to the point where a vertical line descending from the point where a light ray entering the camera parallel to the optical axis intersects the final refracted ray after passing through the lens meets the optical axis. The second principal point may differ from the "principal point" which refers to the center of the lens. Meanwhile, when photographing an object using a wide-angle lens, there are problems such as difficulty in magnifying the subject and difficulty in implementing background blur effects (e.g., bokeh) and / or out-of-focus effects on the subject. Accordingly, to compensate for the disadvantages of wide-angle lenses, a telephoto lens can be used to obtain an enlarged image (img) of a subject; however, when using a telephoto lens, if the distance to the subject is too close (e.g., 20 cm or less), the focus may not be sharp, and a problem may arise where the resolution is significantly degraded. In addition, to obtain high resolution while taking close-up shots using a telephoto lens, a method of forming the focal length of the telephoto lens relatively long can be used; however, in this case, the size of the telephoto lens (e.g., shoulder height of the lens barrel) increases, which may not align with the trend of miniaturization of electronic devices. Therefore, generally, telephoto lenses are not used for close-up shots; however, the present disclosure provides various embodiments of a camera and an electronic device including the same that enable close-up shots using a telephoto lens without causing an increase in size.

[0143] The technical problems to be solved in this disclosure are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this disclosure pertains.

According to one embodiment, among the camera modules, the wide-angle camera, the ultra-wide-angle camera, or the macro camera may have a smaller length in the direction of the optical axis (OI) of the lens(s) compared to the telephoto camera. For example, a telephoto camera with a relatively large adjustment range of focal length may secure a distance or area in which the lens(s) can move by securing sufficient length or space in the direction of the optical axis (OI). In one embodiment, the wide-angle camera, the ultra-wide-angle camera, or the macro camera may have a substantially small effect on the thickness of the electronic device (101) even if the lens(s) are arranged along the direction of the thickness of the electronic device (101) (e.g., thickness measured in the Z-axis direction of FIG. 2 or FIG. 3). For example, a wide-angle camera, an ultra-wide-angle camera, a macro camera, and / or a telephoto camera may be placed in the electronic device (101) such that the direction of light incident from the outside to the electronic device (101) and the direction of the optical axis of the lens(s) are substantially the same. Compared to the wide-angle camera, the ultra-wide-angle camera, or the macro camera, the telephoto camera has a smaller field of view but may be useful for shooting subjects at a greater distance, may include more lens(s), or may have a greater travel distance of the lens(s) for focusing. For example, in the case of the telephoto camera, if the lens(s) are arranged in the thickness direction (e.g., the Z-axis direction) of the electronic device (101), the thickness of the electronic device (101) may increase, or a portion of the telephoto camera may protrude significantly outside the electronic device (101). Below, a telephoto camera (1100) capable of close-up shooting without increasing the size will be described in detail.

[0147] The telephoto camera (1100) of the present disclosure can be applied to a direct-type camera module that does not have a separate reflective member to increase the focal length. According to one embodiment, the telephoto camera may be, for example, a telephoto camera capable of image magnification of 3x to 5x as a telephoto function. However, it is not necessarily limited thereto, and according to one embodiment, the telephoto camera (1100) may further include a reflective member (e.g., a prism and / or a mirror) that can be configured to increase the focal length. According to one embodiment, the telephoto camera (1100) may be configured as a curved camera module including a reflective member.

[0148] According to one embodiment, the telephoto camera (1100) may include a plurality of lenses arranged sequentially along the optical axis (OI) direction from the subject (e.g., the subject (obj) in FIG. 6) to the image sensor (IS). The lenses included in the plurality of lenses may form at least one lens or at least two lens groups (G1, G2) by combining two or more lenses. The present disclosure provides an embodiment (e.g., FIG. 6 to FIG. 30c) comprising a first lens group (G1) and a second lens group (G2) as at least two lens groups (G1, G2), and an embodiment (e.g., FIG. 31 to FIG. 33c) comprising a first lens group (G1), a second lens group (G2), and a third lens group (G3). However, it is not necessarily limited thereto. In the following description of the embodiments of FIGS. 6 to 30c, only the first lens group (G1) and the second lens group (G2) are mentioned, but it should be noted that this may also apply to embodiments that include one or more lens groups (e.g., a third lens group (G3)).

[0149] At least two lens groups (G1, G2), each containing at least one lens, may form a lens assembly arranged sequentially along the optical axis (OI) direction, and these lens assemblies may be surrounded by a lens barrel (not shown). Here, the optical axis direction may mean the thickness (or height) direction of the electronic device (101) (e.g., the Z-axis direction in FIG. 3 or FIG. 4), but is not necessarily limited thereto.

[0150] A telephoto camera (1100) according to one embodiment may include a first lens group (G1) positioned at the first position on the subject side among at least two lens groups (G1, G2) as a configuration included in a lens assembly. The first lens group (G1) may include at least three lenses. The first lens group (G1) may include a first-1 lens (L11) positioned at the first position on the subject side and having positive power, a first-2 lens (L12) positioned at the second position on the subject side, and a first-3 lens (L13) positioned at the furthest position on the subject side. According to one embodiment, the first-3 lens (L13) included in the first lens group (G1) of the present disclosure may have positive power and the image side surface may be formed convexly. Here, the "subject side surface" of a lens may refer to the surface of the lens that is close to the subject when the lens is arranged on the optical axis. Additionally, the term "image side surface" of a lens here may refer to the surface of the lens that is close to the image sensor (I) when the lens is aligned on the optical axis. According to one embodiment, the first lens group (G1) may be formed to have a positive refractive power overall. According to one embodiment, the first-third lens (L13) may have the smallest refractive power among the plurality of lenses included in the first lens group (G1). The present disclosure may provide various embodiments that include such first-third lenses (L13) while not increasing the overall size of the camera.

[0151] In FIG. 6, the telephoto camera (1100) is illustrated with a configuration in which the first lens group (G1) includes three lenses, but it should be noted that this is intended to illustrate a configuration in which one lens group (G1, G2) includes multiple lenses, and that various embodiments of the present disclosure are not limited thereto. For example, the number of lenses included in each lens group (G1, G2) can be selected in various ways as long as the conditions presented in various embodiments are satisfied. For example, the number of lenses included in each lens group (G1, G2) may include four or more lenses.

[0152] A telephoto camera (1100) according to one embodiment may include a second lens group (G2) positioned at the second position on the subject side among at least two lens groups (G1, G2) as a configuration included in a lens assembly. The second lens group (G2) may include at least three lenses. The second lens group (G2) may include a second-1 lens (L21) positioned at the first position on the subject side, a second-2 lens (L22) positioned at the second position on the subject side, and a second-3 lens (L23) positioned at the furthest position on the subject side. According to one embodiment, the second-3 lens (L23) included in the second lens group (G2) of the present disclosure may have a negative refractive power.

[0153] According to one embodiment, the lens(s) included in each lens group (G1, G2) may be made of a synthetic resin material (e.g., plastic) and may have a high degree of design freedom regarding size or shape. Lenses made of synthetic resin material may have a variation in resolution due to changes in temperature or humidity, and in a telephoto camera (1100) with a long focal length, the variation in resolution may be greater than in a standard camera or a wide-angle camera. According to one embodiment, the telephoto camera (1100) may suppress the variation in resolution according to the operating environment by making at least one of the lenses in the first lens group (G1) and / or at least one of the lenses in the second lens group (G2) of a glass material.

[0154] According to one embodiment, the lens(s) included in each lens group (G1, G2) may include aspherical lenses. According to one embodiment, all lenses included in each lens group (G1, G2) may be composed of aspherical lenses. The telephoto camera (1100) of the present disclosure can reduce its size by using aspherical lenses. If spherical lenses are used, the speed of autofocus (AF) can be increased, but it may be disadvantageous for reducing the size of the telephoto camera.

[0155] In the present disclosure, among at least two lens groups (G1, G2), the position of the first lens group (G1) positioned first from the subject side is fixed, and the second lens group (G2) positioned second from the subject side can move back and forth along the optical axis (OI) direction between the first lens group (G1) and the image sensor (IS). The telephoto camera (1100) can perform a focus adjustment operation (focusing) based on the back-and-forth movement of the second lens group (G2). The telephoto camera (1100) (or the processor (120) of FIG. 1) can perform an autofocus adjustment operation (hereinafter referred to as 'AF (auto focusing) operation') using the second lens group (G2). According to one embodiment, a high-resolution image can be obtained when taking close-up shots using the telephoto camera through the focus adjustment operation. When a focus adjustment operation is performed using the first lens group (G1) or by using both the first lens group (G1) and the second lens group (G2), the distance from the vertex of the first lens on the subject side of the first lens group (G1) to the image sensor (hereinafter, overall length) is increased, and the height of the telephoto camera corresponding to the direct-type camera module may be increased. In the present disclosure, by performing a focus adjustment operation using only the second lens group (G2), close-up shooting can be performed using the telephoto camera without a decrease in resolution or a change in the height of the telephoto camera. For example, the electronic device (101), the telephoto camera (1100), or the processor (120) of FIG. 1 can adjust the focus (e.g., AF drive) by moving the second lens group (G2) back and forth in the direction of the optical axis (OI) while the first lens group (G1) is fixed.

[0156] If at least two lens groups (G1, G2) include a third lens group (G3), the third lens group (G3) may also be fixed. When the magnification is adjusted by moving the third lens group (G3), precise control for AF driving is required because the magnification is high and AF sensitivity is high; however, when the third lens group (G3) is fixed as in the present disclosure, the AF sensitivity is relatively lower, so problems that may occur as AF sensitivity increases can be prevented. When the focus is adjusted by moving the third lens group (G3), precise control for AF driving is required because the magnification is high and AF sensitivity is high; however, when the third lens group (G3) is fixed as in the present disclosure, the AF sensitivity is relatively lower, so problems that may occur as AF sensitivity increases can be prevented.

[0157] The focus adjustment operation using at least two lens groups (G1, G2) as described above may be different from the magnification adjustment operation (or zooming operation) which adjusts the magnification by adjusting the distance between lenses using multiple lens groups in at least two lens groups (G1, G2).

[0158] In the above embodiments, when describing the zooming operation and / or focus adjustment operation of the telephoto camera (1100), only the movement and / or fixation of at least two lens groups (G1, G2) were mentioned. However, when moving any one of the at least two lens groups (G1, G2), the embodiments regarding the movement and / or fixation of the lens(s) included in the lens group may vary. For example, when a second lens group (G2) including a plurality of lenses moves in the direction of the optical axis, the plurality of lenses included in the second lens group (G2) may all move in the direction of the optical axis by the same distance, or at least some of the lenses included in the plurality of lenses may move by different distances relative to other lenses, and depending on the embodiment, it is also possible for some lenses to have their positions substantially fixed.

[0159] The drawing shown above in FIG. 6 illustrates an arrangement of lenses (groups) included in a camera (e.g., a telephoto camera) when the focal position corresponds to the infinity position. The drawing shown below in FIG. 6 illustrates an arrangement of lenses (groups) included in a camera (e.g., a telephoto camera) when the focal position corresponds to the nearest distance to the subject.

[0160] In an embodiment of the camera (e.g., telephoto camera) of the present disclosure, "the focal position corresponds to an infinity position" may mean an arrangement state of the second lens group (G2) such that the focal position of the telephoto camera (1100) is maximized (or infinity) within the movable range of the second lens group (G2). This may also be expressed as "setting the focus of the camera to infinity." "The focal position corresponds to the nearest distance of the subject" may mean an arrangement state of the second lens group (G2) such that the focal position of the telephoto camera (1100) is minimized (or approximately 10 cm) from the subject within the movable range of the second lens group (G2). Note that when indicating the reference numerals for the surfaces of the lenses (L11, L12, L13, L21, L22, L23) included in the telephoto camera (1100), for convenience, only the lens (group) array is indicated when the focal position corresponds to infinity. The telephoto camera (1100) can be adjusted so that the focal position is from infinity to the nearest distance to the subject, or the focal position is adjusted from the nearest distance to the subject to infinity. Additionally, the telephoto camera (1100) can be adjusted so that the focal position is between the state where the focal position is infinity and the state where the focal position corresponds to the nearest distance to the subject. According to one embodiment, changes in the lens array can be implemented continuously in the state where the focal position is infinity, the state where the focal position is at the nearest distance to the subject, and the state in between.

[0161] Among at least two lens groups (G1, G2), the first lens group (G1) may be positioned first on the subject side and may have positive power while including at least three lenses (L11, L12, L13). That the first lens group (G1) has positive power may mean that the sum of the refractive powers of the lenses included in the first lens group (G1) has positive power. The first lens group (G1) may include lenses with positive power and lenses with negative power. Referring to FIG. 6, in one embodiment, the first-1 lens (L11) and the first-3 lens (L13) positioned first on the subject side of the first lens group (G1) may have positive power, and the first-2 lens (L12) of the first lens group (G1) may have negative power. And the 1st-3rd lens (L13) may have the smallest refractive power.

[0162] In one embodiment, the first-1 lens (L11) may have a subject (obj) side surface (S1) that is convex toward the subject side (O). The upper side surface (S2) of the first-1 lens (L11) may be formed to be convex or concave toward the image (img) side (I). If the upper side (I) surface (S2) of the first-1 lens (L11) is convex, the subject side (O) surface (S3) of the first-2 lens (L12) may be concave. Conversely, if the upper side surface (S2) of the first-1 lens (L11) is concave, the subject (obj) side surface (S3) of the first-2 lens (L12) may be convex. FIG. 6 illustrates an embodiment in which the upper side surface (S2) of the first-1 lens (L11) is concave and the subject side surface (S3) of the first-2 lens (L12) is convex. According to the embodiment, the first lens group (G1) may further include at least one lens having positive or negative refractive power. The upper side surface (S4) of the first-2 lens (L12) may be concave. According to one embodiment, the subject side surface (S5) of the first-3 lens (L13) may be formed flat or concave. And in the present disclosure, the upper side surface (S6) of the first-3 lens (L13) may be formed convex toward the upper side (I).

[0163] Referring to FIG. 6, the subject-side surface (S7) of the second-1 lens (L21) may be convex toward the subject side (O). The upper surface (S8) of the second-1 lens (L21) may be formed concave toward the upper side (I). The subject-side surface (S9) of the second-2 lens (L22) may be concave toward the subject side (O), and the upper surface (S10) of the second-2 lens (L22) may be concave toward the upper side (I). That is, the second-2 lens (L22) according to one embodiment may have a double concave shape. In the present disclosure, the subject-side surface (S11) of the second-3 lens (213) may be convex toward the subject side (O). And the upper surface (S12) of the second-third lens (L23) can be formed convexly toward the upper side (I).

[0164] In one embodiment, the telephoto camera (1100) can satisfy the conditions disclosed through the following [Equation 1].

[0165] [Equation 1]

[0166] Nd1-L < 1.62

[0167] Here, Nd1-L corresponds to the refractive index of the last lens of the first lens group (G1). In the embodiment of FIG. 6, the refractive index of the first-third lens (L13) may correspond. If the refractive index of the last lens of the first lens group (e.g., the first-third lens (L13)) is 1.62 or greater, field curvature aberration increases, and the size of the telephoto camera (1100) may need to be increased to compensate for this. Alternatively, adding lenses to minimize field curvature aberration may increase manufacturing costs.

[0168] In one embodiment, the telephoto camera (1100) may satisfy the condition disclosed through the following [Equation 2] additionally or substantially with respect to [Equation 1].

[0169] [Equation 2]

[0170] -1.5 < EFL1-1 / EFL1-2 < -0.9

[0171] Here, EFL1-1 corresponds to the focal length of the first lens from the subject side of the first lens group (G1). EFL1-2 corresponds to the focal length of the second lens from the subject side of the first lens group (G1). In the embodiment of FIG. 6, EFL1-1 is the focal length of the first-1 lens (L11), and EFL1-2 is the focal length of the first-2 lens (L12). If [Equation 2] is -1.5 or smaller, the sensitivity of the second lens (e.g., the first-2 lens (L12)) from the subject side of the first lens group (G1) increases, making manufacturing difficult. If [Equation 2] is -0.9 or larger, the sensitivity of the second lens group (G2) of the telephoto camera (1100) may increase. Accordingly, there may be a significant change in performance during autofocus operation.

[0172] In one embodiment, the telephoto camera (1100) may satisfy the condition disclosed through the following [Equation 3] additionally or substantially with respect to [Equation 1] and / or [Equation 2].

[0173] [Equation 3]

[0174] -5 < L1R2 / EFL1-1 < 15

[0175] Here, L1R2 may be the curvature of the image plane side of the first lens from the subject side in the first lens group (G1). In FIG. 6, L1R2 may be the curvature of the image plane (S2) side of the first-1 lens (L11). EFL1-1 corresponds to the focal length of the first lens from the subject side in the first lens group (G1). If [Equation 3] is -5 or smaller, the spherical aberration of the first lens group (G1) increases, and sensitivity may increase. Additionally, the deviation in resolution according to the focal position may become large. If [Equation 2] is 15 or larger, the spherical aberration of the telephoto camera (1100) increases, and resolution may decrease.

[0176] In one embodiment, the telephoto camera (1100) may satisfy the condition disclosed through the following [Equation 4] additionally or substantially with respect to [Equation 1], [Equation 2] and / or [Equation 3].

[0177] [Equation 4]

[0178] 0.9 < L1R1 / 1G_T < 1.5

[0179] Here, L1R1 may be the curvature of the first lens on the subject side from the subject side in the first lens group (G1). 1G_T is the distance from the vertex on the subject surface side of the first lens in the first lens group (G1) to the vertex on the image surface side of the last lens. In the embodiment of FIG. 6, 1G_T may be the distance from the vertex on the subject surface (S1) of the first-1 lens (L11) to the vertex on the image surface side (S6) of the first-3 lens (L13). If [Equation 4] is 0.9 or smaller than that, the overall size of the telephoto camera (1100) increases, which may be disadvantageous for miniaturizing the electronic device including it. If [Equation 4] is 1.5 or larger than that, the image surface curvature aberration of the telephoto camera (1100) increases, which may degrade the performance of the entire optical system.

[0180] According to the embodiment of FIG. 6, the telephoto camera (1100) may further include an infrared blocking filter (F) positioned between the second lens group (G2) and the image sensor (IS). Infrared rays are not substantially identifiable to the naked eye but can be detected by a photosensitive film or the image sensor (IS). By blocking infrared rays incident on the image sensor (IS), the infrared blocking filter (F) can mitigate or prevent the degradation of the quality of the captured image.

[0181] According to one embodiment, the telephoto camera (1100) may further include an aperture (sto), and at least one of the lenses (L11, L12, L13, L21, L22, L23) or the aperture may be of a shape that is not circular. For example, at least one of the lenses (L11, L12, L13, L21, L22, L23) and / or the aperture may be elliptical in shape, or generally circular but with at least a portion of the edges in a straight line shape (e.g., D-cut shape). According to one embodiment, the aperture may be positioned between the last lens on the subject side of the first lens group (G1) (e.g., the first-third lens (L13)) and the first lens on the subject side of the second lens group (G2) (e.g., the second-first lens (L21)).

[0182] According to one embodiment, if the lens(s) or aperture has a shape other than a circular shape, the edge of the effective aperture may be partially exposed to the outside of the lens(s) due to a partial curvature deviation or a D-cut shape at the edge of the effective aperture. Such shapes of the lens(s) may cause flare and may exacerbate variations in the quality of the captured image depending on the shooting environment. According to one embodiment, the flare phenomenon may be suppressed or mitigated by black painting, digging, and / or carbonation treatment at the edge of the lens(s).

[0183] Although reference numbers or detailed descriptions in the drawings have been omitted, the telephoto camera (1100) and the electronic device (101) including it may further include a lens barrel for positioning the lens(s) at a designated location, and / or a driving device for moving the lens(s) or the second lens group (G2) among at least two lens groups (G1, G2) back and forth along the optical axis direction for focusing. In one embodiment, the telephoto camera (1100) or the electronic device (101) may further include another driving device for moving the first lens group (G1) in a direction substantially perpendicular to the optical axis (OI) direction. According to one embodiment, an optical image stabilization (OIS) operation can be performed by moving the first lens group (G1).

[0185] FIGS. 7a and FIGS. 8a are graphs illustrating spherical aberration of a telephoto camera (1100), wherein the horizontal axis represents the coefficient of longitudinal spherical aberration and the vertical axis represents the distance from the optical axis normalized, and the change in longitudinal spherical aberration according to the wavelength of light is illustrated. Longitudinal spherical aberration is measured based on light with wavelengths of, for example, 656.3000 nm, 587.6000 nm, 546.1000 nm, 486.1000 nm and / or 435.8000 nm. FIGS. 7b and FIGS. 8b are graphs illustrating the astigmatism of a telephoto camera (1100) for light with a wavelength of 546.1000 nm, where 'S' illustrates the sagittal plane as a solid line and 'T' illustrates the tangential plane or meridional plane as a dotted line. FIGS. 7c and FIGS. 8c are graphs illustrating the distortion rate of a telephoto camera (1100) for light with a wavelength of 546.1000 nm. The refractive index of the lens(s) mentioned in the embodiments described below may refer to the refractive index for light with a wavelength of approximately 587.6000 nm.

[0186] Referring to FIGS. 7a through 8c, a telephoto camera (e.g., telephoto camera (1100) of FIG. 6) may satisfy at least one of the configurations mentioned in the above-described embodiments or the conditions presented through [Equation 1], [Equation 2], [Equation 3] and / or [Equation 4], and may include a first lens group (G1), a second lens group (G2), an infrared blocking filter (F), and / or an image sensor (IS) (e.g., a sensor plane or an imaging plane (img)) arranged sequentially from the side of the subject (obj). The first lens group (G1) may include three lenses (L11, L12, L13), and the second lens group (G2) may include three lenses (L21, L22, L23). In one embodiment, the focal length of the telephoto camera (1100) can be adjusted according to the forward and backward movement of the second lens group (G2) so that the depth of field becomes from maximum distance to minimum distance (or from minimum distance to maximum distance).

[0187] [Table 1] below describes lens data of the telephoto camera (1100) exemplified in FIGS. 6 to 8c. 'obj' may mean a subject. Additionally, 'S1~S14' may refer to the surfaces of a plurality of related lenses (e.g., L11, L12, L13, L21, L22, L23) and / or a filter (F). Data for the subject side surface (S1) and image side surface (S2) of the first-1 lens (L11) included in the first lens group (G1) of the telephoto camera (1100), the subject side surface (S3) and image side surface (S4) of the first-2 lens (L12), and the subject side surface (S5) and image side surface (S6) of the first-3 lens (L13) are included in [Table 1]. In addition, data regarding the subject side (S7) and image side (S8) of the 2-1 lens (L21) included in the 2-1 lens group (G2) of the telephoto camera (1100), the subject side (S9) and image side (S10) of the 2-2 lens (L22), and the subject side (S11) and image side (S12) of the 2-3 lens (L23) are included in [Table 1]. Also, data regarding the subject side (S13) and image side (S14) of the infrared blocking filter (F) and data regarding the image plane (img) of the image sensor (IS) may also be included in [Table 1]. The image plane (img) can receive or detect light aligned or focused by a plurality of lenses (e.g., L11, L12, L13, L21, L22, L23). For example, the imaging plane (img) can be understood as the active area of ​​the image sensor (IS).

[0188] Here, 'sto' may indicate the position of the aperture stop (or stop) as a location considered in the lens assembly design, rather than the lens surface. Also, radius may indicate the radius of curvature of the lens (e.g., radius), thickness may indicate the thickness of the lens or the air gap, Nd may indicate the refractive index of the medium (e.g., lens), and Vd may indicate the Abbe number of the lens. The radius of curvature may represent, for example, a value indicating the degree of curvature at each point of a curved surface or curve. Regarding the thickness, the thickness indicated on the surface facing the subject side (e.g., S1) of a certain lens (e.g., the first-1 lens (L11)) may indicate the thickness of the lens, and the thickness value indicated on the surface facing the image side of a certain lens may be described as the air gap from that lens to the lens located behind it in the direction of the optical axis. For example, the thickness value indicated on the upper side surface (S2) of the first-1 lens (L11) may be data for indicating the air gap to the surface (S3) facing the subject side of the first-2 lens (L12). The telephoto camera (1100) included in [Table 1] below may satisfy the above-described equation (and / or at least one of the above-described conditions) when the F-number (Fno) is approximately 2.473, the effective focal length (EFL) is approximately 11 mm, and the optical total track length (OTTL) is 10.800 mm.
