Description

Technical Field

[0001] This application relates to the field of optical lenses, specifically to an optical lens, a camera module, and an electronic device. Background Technology

[0002] With the development of technology, the demand for photography in electronic devices (such as mobile phones) is increasing, with wider zoom ranges and higher image quality placing higher requirements on mobile phone lenses.

[0003] Typically, high-magnification optical zoom in mobile phone lenses is achieved through "skip-like" zoom, using two to three lenses with different focal lengths, combined with algorithm-based digital zoom to achieve hybrid optical zoom. Currently, lenses that achieve continuous zoom using a single lens are usually quite large, which is not conducive to the miniaturization design of electronic devices. Summary of the Invention

[0004] This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first optical element, a second optical element, a third optical element, and a fourth optical element arranged from the object side to the image side. By designing the third and fourth optical elements for zooming, continuous zooming of the optical lens is achieved. By designing the first optical element to have positive optical power and the second optical element for image stabilization, miniaturization of the optical lens is achieved.

[0005] In a first aspect, this application provides an optical lens. The optical lens enables continuous optical zoom between a telephoto end and a wide-angle end. The field of view (FOV) at the telephoto end is less than 20°, and the FOV at the wide-angle end is greater than 20° and less than 40°. The optical lens includes a first optical element, a second optical element, a third optical element, and a fourth optical element arranged from the object side to the image side. The first optical element has positive optical power and changes the propagation direction of the optical axis from a first direction to a second direction, which is different from the first direction. During zooming, the first and second optical elements are fixed lens groups, while the third and fourth optical elements move along the second direction. Some or all of the lenses in the second optical element are image-stabilizing optical elements. During image stabilization, the image-stabilizing optical elements move along the first direction and / or the third direction, which is different from both the first and second directions.

[0006] In this application, the optical lens is a telephoto lens, capable of continuous zoom by moving along a second direction via a third and fourth optical element. Specifically, it enables the optical lens to switch between multiple states, such as between a telephoto end and a wide-angle end.

[0007] In this application, the first optical element has positive optical power, which enables it to focus light, thereby increasing the amount of light entering the first optical element and thus increasing the overall light intake of the optical lens, which in turn improves the imaging quality of the camera module. Furthermore, having positive optical power also helps to shorten the overall length of the camera module, facilitating its miniaturization.

[0008] In this application, image stabilization is achieved by driving the movement of the second optical element, allowing different optical elements to perform image stabilization and zooming respectively. This facilitates the staggered arrangement of the image stabilization drive mechanism and the zoom drive mechanism, thereby promoting miniaturization. Furthermore, since the image stabilization structure is not located on the first optical element, the size of the reflective structure in the first optical element can be avoided, thus preventing the first optical element from becoming too large, which in turn facilitates the overall miniaturization design of the camera module.

[0009] In some possible implementations, the focal length Fg1 of the first optical element and the focal length Fo of the image stabilization optical element satisfy: Fg1>|Fo|.

[0010] In this implementation, the focal length Fo of the image stabilization optical element satisfies the above-mentioned relationship, allowing for a higher optical power setting of the image stabilization optical element. This improves the light bending capability of the image stabilization optical element, thereby enhancing the image quality of the camera module. Furthermore, it reduces the movement of the image stabilization optical element while maintaining high optical performance, which is beneficial for achieving image stabilization.

[0011] In some possible implementations, the combined focal length Ft of the first optical element to the image stabilization optical element and the focal length Fo of the image stabilization optical element satisfy: 0.40 < |Ft| / |Fo| < 5.00.

[0012] In this implementation, by setting the focal length Fo of the image stabilization optical element to satisfy the above relationship, the amount of movement of the image stabilization optical element can be suppressed while maintaining the optical performance of the image stabilization optical element, which is beneficial to achieving image stabilization.

[0013] In some possible implementations, the first optical element includes a first lens group and an optical path reversing element; the first lens group is located on the object side of the optical path reversing element and has positive optical power; the optical path reversing element has a reflecting surface for changing the propagation direction of the optical axis from a first direction to a second direction.

[0014] In this implementation, the first optical element has positive optical power, which enables it to have a light-gathering effect, allowing as much external light as possible to enter the optical path refracting element. This increases the light intake of the entire first optical element, which in turn helps to increase the light intake of subsequent optical elements.

[0015] In some possible implementations, the first lens group includes one or two lenses with positive optical power to improve the light-gathering ability of the first lens group, thereby facilitating an increase in the amount of light entering the first optical element.

[0016] In some possible implementations, the optical path turning element is a prism, which facilitates the fixed installation of the first lens group and the optical path turning element, thereby improving the overall stability of the first optical element.

[0017] In some other possible implementations, the optical path deflection element is a mirror, and the reflecting surface can be a plane to ensure good manufacturability.

[0018] In some possible implementations, the object-side surface of the first lens group serves as the incident surface of the first optical element, and the distance Tg1r between the incident surface and the reflecting surface along the optical axis satisfies the following condition: 0.5. <Tgo / Tg1r<2.0。

[0019] In this implementation, the thickness Tgo of the second optical element along the optical axis satisfies the above relationship. While maintaining the optical performance of the image stabilization optical element, the height of the first optical element, i.e. the dimension in the first direction, can be reduced, thereby reducing the overall height of the optical lens and facilitating the miniaturization design of the optical lens.

[0020] In some possible implementations, the thickness Tg1 of the first optical element along the optical axis and the thickness To of the image stabilization optical element along the optical axis satisfy: 0.05 < |To| / |Tg1| < 1.00.

[0021] In this implementation, the thickness To of the image stabilization optical element along the optical axis satisfies the above relationship, which can reduce the weight of the image stabilization optical element while maintaining its optical performance. This is beneficial for reducing the driving force required for image stabilization, thereby achieving energy saving and miniaturization.

[0022] The thickness Tg1 of the first optical element along the optical axis and the thickness To of the image stabilization optical element along the optical axis can satisfy: 0.1 < |To| / |Tg1| < 0.6. For example, the value of |To| / |Tg1| can be, but is not limited to, 0.11, 0.12, 0.14, 0.19, 0.20, 0.3, 0.4, 0.51, 0.55, 0.59, or other values ​​between 0.1 and 0.6.

[0023] In this implementation, the thickness To of the image stabilization optical element along the optical axis satisfies the above relationship, which can further reduce the weight of the image stabilization optical element while maintaining its optical performance. This is beneficial for reducing the driving force required for image stabilization, thereby further achieving energy saving and miniaturization.

[0024] In some possible implementations, the absolute value of the focal length Fg2 of the second optical element and the absolute value of the focal length Fg3 of the third optical element satisfy: |Fg2|>|Fg3|.

[0025] In this implementation, the absolute value of the focal length Fg2 of the second optical element and the absolute value of the focal length Fg3 of the third optical element satisfy the above relationship, which is beneficial to improve the optical performance of the optical lens while realizing continuous zoom of the optical lens.

[0026] In some possible implementations, the absolute value of the focal length Fg2 of the second optical element and the absolute value of the focal length Fg3 of the third optical element satisfy: 1.00 < |Fg2 / Fg3| < 3.00.

[0027] In this implementation, the absolute value of the focal length Fg2 of the second optical element and the absolute value of the focal length Fg3 of the third optical element satisfy the above relationship, which is beneficial to further improve the optical performance of the optical lens while realizing continuous zoom of the optical lens.

[0028] In some possible implementations, the focal length Fg1 of the first optical element satisfies: 30mm≤Fg1≤130mm;

[0029] And / or, the focal length Fg2 of the second optical element satisfies: -30mm≤Fg2≤-15mm;

[0030] And / or, the focal length Fg3 of the third optical element satisfies: 10mm≤Fg3≤20mm;

[0031] And / or, the focal length Fg4 of the fourth optical element satisfies: -20mm≤Fg4≤35mm.

[0032] In some possible implementations, the spacing between the second and third optical elements along the optical axis varies in the range of 0.4 mm to 8.5 mm;

[0033] And / or, the spacing between the third and fourth optical elements along the optical axis varies from 1 mm to 13.5 mm.

[0034] In some possible implementations, the third optical element has positive optical power and the fourth optical element has negative optical power;

[0035] Alternatively, the third optical element may have negative optical power, and the fourth optical element may have positive optical power.

[0036] In this implementation, the combination of positive and negative optical power facilitates the continuous zoom function of the third and fourth optical elements and helps to eliminate aberrations, thereby improving image quality.

[0037] In some possible implementations, the optical lens also includes a fifth optical element located on the image side of the fourth optical element, which moves along the second direction during zooming.

[0038] The focal length Fg5 of the fifth optical element satisfies: -110mm≤Fg5≤-14mm.

[0039] In some possible implementations, the spacing between the fourth and fifth optical elements along the optical axis varies from 2 mm to 5.5 mm.

[0040] In some possible implementations, at least one of the third, fourth, and fifth optical elements is positive optical power and at least one is negative optical power.

[0041] In this implementation, the combination of optical elements with positive and negative optical power facilitates continuous zoom function and helps to eliminate aberrations, thereby improving image quality.

[0042] Secondly, this application also provides an optical lens. The optical lens enables continuous optical zoom between a telephoto end and a wide-angle end. The field of view (FOV) at the telephoto end is less than 20°, and the FOV at the wide-angle end is greater than 20° and less than 40°. The optical lens includes a first fixed optical element, a second fixed optical element, a first zoom optical element, and a second zoom optical element. The first zoom optical element is located on the image side of the first fixed optical element, and both the second fixed optical element and the second zoom optical element are located on the image side of the first zoom optical element. The first fixed optical element has positive optical power and changes the propagation direction of the optical axis from a first direction to a second direction, which is different from the first direction. During zooming, the first and second fixed optical elements are fixed lens groups, and the first and second zoom optical elements move along the second direction. Some or all of the lenses in the second fixed optical element are image stabilization optical elements. During image stabilization, the image stabilization optical elements can move along the first direction and / or a third direction, which is different from both the first and second directions.

[0043] In this application, the optical lens is a telephoto lens, capable of continuous zooming by moving along a second direction via a first zoom optical element and a second zoom optical element. Specifically, it enables the optical lens to switch between multiple states, such as between a telephoto end and a wide-angle end.

[0044] In this application, the first fixed optical element has a positive optical power, which enables it to focus light, thereby increasing the amount of light entering the first fixed optical element and thus increasing the overall light intake of the optical lens, which in turn improves the imaging quality of the camera module. Furthermore, having a positive optical power for the first fixed optical element also helps to shorten the overall length of the camera module, facilitating its miniaturization.

[0045] In this application, image stabilization is achieved by driving the second fixed optical element to move, allowing different optical elements to perform image stabilization and zooming respectively. This facilitates the staggered arrangement of the image stabilization drive mechanism and the zoom drive mechanism, thereby promoting miniaturization. Furthermore, since the image stabilization structure is not located on the first fixed optical element, the size of the reflective structure in the first fixed optical element can be avoided, thus preventing the size of the first fixed optical element from becoming too large, which in turn facilitates the overall miniaturization design of the camera module.

[0046] In some possible implementations, the focal length Fg1 of the first fixed optical element and the focal length Fo of the image stabilization optical element satisfy: Fg1>|Fo|.

[0047] In this implementation, the focal length Fo of the image stabilization optical element satisfies the above-mentioned relationship, allowing for a higher optical power setting of the image stabilization optical element. This improves the light bending capability of the image stabilization optical element, thereby enhancing the image quality of the camera module. Furthermore, it reduces the movement of the image stabilization optical element while maintaining high optical performance, which is beneficial for achieving image stabilization.

[0048] In some possible implementations, the combined focal length Ft of the first fixed optical element to the image stabilizing optical element and the focal length Fo of the image stabilizing optical element satisfy: 0.40 < |Ft| / |Fo| < 5.00.

[0049] In this implementation, by setting the focal length Fo of the image stabilization optical element to satisfy the above relationship, the amount of movement of the image stabilization optical element can be suppressed while maintaining the optical performance of the image stabilization optical element, which is beneficial to achieving image stabilization.

[0050] In some possible implementations, the first fixed optical element includes a first lens group and an optical path reversing element; the first lens group is located on the object side of the optical path reversing element and has positive optical power; the optical path reversing element has a reflecting surface for changing the propagation direction of the optical axis from a first direction to a second direction.

[0051] In this implementation, the first fixed optical element has a positive optical power, which enables it to have a light-gathering effect, allowing as much external light as possible to enter the optical path refracting element. This increases the light intake of the entire first fixed optical element, which in turn helps to increase the light intake of subsequent optical elements.

[0052] In some possible implementations, the object-side surface of the first lens group serves as the incident surface of the first fixed optical element. The distance Tg1r between the incident surface and the reflecting surface along the optical axis and the thickness Tgo of the second fixed optical element along the optical axis satisfy: 0.5 <Tgo / Tg1r<2.0。

[0053] In this implementation, the thickness Tgo of the second fixed optical element along the optical axis satisfies the above relationship. While maintaining the optical performance of the image stabilization optical element, the height of the first fixed optical element, i.e. the dimension in the first direction, can be reduced, thereby reducing the overall height of the optical lens and facilitating the miniaturization design of the optical lens.

[0054] In some possible implementations, the thickness Tg1 of the first fixed optical element along the optical axis and the thickness To of the image stabilization optical element along the optical axis satisfy: 0.05 < |To| / |Tg1| < 1.00.

[0055] In this implementation, the thickness To of the image stabilization optical element along the optical axis satisfies the above relationship, which can further reduce the weight of the image stabilization optical element while maintaining its optical performance. This is beneficial for reducing the driving force required for image stabilization, thereby further achieving energy saving and miniaturization.

[0056] In some possible implementations, the second fixed optical element is located between the first zoom optical element and the second zoom optical element;

[0057] The first zoom optical element has negative optical power, the second fixed optical element has positive optical power, and the second zoom optical element has negative optical power.

[0058] In this implementation, the combination of optical elements with positive and negative optical power facilitates continuous zoom function and helps to eliminate aberrations, thereby improving image quality.

[0059] In some possible implementations, the absolute value of the focal length Fg2 of the first zoom optical element and the absolute value of the focal length Fg3 of the second fixed optical element satisfy: |Fg2|>|Fg3|.

[0060] In this implementation, the absolute value of the focal length Fg2 of the first zoom optical element and the absolute value of the focal length Fg3 of the second fixed optical element satisfy the above relationship, which is beneficial to improve the optical performance of the optical lens while realizing continuous zoom of the optical lens.

[0061] In some possible implementations, the absolute value of the focal length Fg2 of the first zoom optical element and the absolute value of the focal length Fg3 of the second fixed optical element satisfy: 1.00 < |Fg2 / Fg3| < 3.00.

[0062] In this implementation, the absolute value of the focal length Fg2 of the first zoom optical element and the absolute value of the focal length Fg3 of the second fixed optical element satisfy the above relationship, which is beneficial to further improve the optical performance of the optical lens while realizing continuous zoom of the optical lens.

[0063] In some possible implementations, the focal length Fg1 of the first fixed optical element satisfies: 30mm≤Fg1≤130mm;

[0148] For ease of understanding, the English abbreviations and related technical terms used in the embodiments of this application will be explained and described below.

[0149] Focal power is equal to the difference between the convergence of the image-side beam and the convergence of the object-side beam; it characterizes the ability of an optical system to deflect light rays.

[0150] A lens or lens group with positive optical power, having a positive focal length, and having the effect of converging light.

[0151] A lens or lens group with negative optical power has a negative focal length and has the effect of diverging light.

[0152] Focal length, also known as focal length, is a measure of the convergence or divergence of light in an optical system. It refers to the perpendicular distance from the optical center of a lens or lens group to the focal plane when a distant object is projected into a sharp image. From a practical perspective, it can be understood as the distance from the center of the lens to the focal plane when the object is at infinity. For fixed-focus lenses, the position of their optical center remains constant; for optical lenses, changes in the optical center result in changes in the focal length.

[0153] The object side is defined by the lens; the side where the object is located is called the object side, and the surface of the lens closest to the object side is called the object side surface.

[0154] The image side is the side on which the image of the object is located, with the lens as the boundary. The surface of the lens closest to the image side is called the image side surface.

[0155] An aperture diaphragm is a device used to control the amount of light passing through the lens and entering the sensor inside the camera body; it is usually located inside the lens.

[0156] Aperture value, also known as F-number (Fno), is a relative value derived from the lens's focal length and entrance pupil diameter (the reciprocal of the relative aperture). A smaller aperture value allows more light to enter the lens in the same unit of time. A larger aperture value results in a shallower depth of field, blurring the background and creating an effect similar to that of an optical lens.

[0157] The imaging plane is located on the image side of all lenses in an optical lens, and is the surface on which light rays pass through each lens in the optical lens in sequence to form an image.

[0158] The optical axis is a perpendicular axis passing through the center of a lens. The lens optical axis is the axis passing through the centers of all the lenses in the lens. When light rays parallel to the optical axis enter a convex lens, an ideal convex lens should have all the light rays converging at a single point behind the lens; this point where all the light rays converge is called the focal point.

[0159] The focal point is the point where parallel light rays converge after being refracted by a lens or lens group.

[0160] The Abbe number, also known as the dispersion coefficient, is the ratio of the difference in refractive index of an optical material at different wavelengths, representing the degree of dispersion of the material.

[0161] The field of view (FOV) in optical instruments is the angle between the two edges of the lens, representing the maximum range through which the image of the target object can pass through the lens. The size of the FOV determines the field of view of the optical instrument; a larger FOV results in a wider field of view but a lower optical magnification.

[0162] The half-sensor diagonal ImgH (Image Hight) represents half the diagonal length of the effective pixel area on the image sensor, which is also the image height of the imaging surface.

[0163] Aberrations are the properties of an ideal optical system in the paraxial region. Paraxial rays emitted from a point on an object intersect the image plane at a single point (i.e., the paraxial image point). However, in reality, rays passing through different apertures of a lens rarely intersect perfectly at a single point. Instead, they deviate from the position of the paraxial image point. These differences are collectively referred to as aberrations.

[0164] Axial spherical aberration, also known as longitudinal chromatic aberration, positional chromatic aberration, or axial aberration, occurs when a beam of light parallel to the optical axis converges at different positions after passing through a lens. This aberration is called positional chromatic aberration or axial chromatic aberration. This is because the lens images different wavelengths of light at different positions, causing the image-side focal planes of different colors of light to not coincide, resulting in the dispersion of polychromatic light.

[0165] Distortion, also known as image distortion, refers to the degree of distortion in the image formed by an optical system relative to the object itself. Distortion occurs due to the spherical aberration of the aperture. The height of the intersection point between the principal ray from different fields of view and the Gaussian image plane is not equal to the ideal image height; this difference is the distortion. Therefore, distortion only changes the imaging position of an off-axis object point on the ideal plane, causing a distortion in the image shape, but it does not affect the image's sharpness.

[0166] Astigmatism occurs because the object point is not on the optical axis of the optical system, and the emitted beam of light has an angle with the optical axis. After refraction by a lens, the convergence points of the meridional and sagittal beams are not at the same point. That is, the beam cannot be focused on a single point, resulting in an unclear image, hence astigmatism. The meridional and sagittal beams are the names of beams in two perpendicular planes within a rotationally symmetric optical system.

[0167] The meridional plane is the plane formed by the principal ray (principal beam) of an object point outside the optical axis and the optical axis.

[0168] The sagittal surface is the plane that passes through the principal ray (principal beam) of an object point outside the optical axis and is perpendicular to the meridional plane.

[0169] Field curvature refers to the difference in optical axis between the position of the sharpest image point after rays from the off-center field of view pass through an optical lens assembly and the position of the sharpest image point in the center field of view. When a lens has field curvature, the intersection of the entire beam does not coincide with the ideal image point. Although a sharp image point can be obtained at each specific point, the entire image plane is a curved surface.

[0170] The embodiments of this application are described below with reference to the accompanying drawings.

[0171] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" refers to at least two.

[0172] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0173] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0174] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0175] Please refer to the following: Figure 1A and Figure 1B , Figure 1A This is a schematic diagram of the structure of the electronic device 100 provided in some embodiments of this application; Figure 1B yes Figure 1AA partially exploded structural diagram of the electronic device 100 shown.

[0176] In some embodiments, the electronic device 100 may be a mobile phone, tablet personal computer, laptop computer, smart screen, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, or other devices with camera functions. Figure 1A In this embodiment, the electronic device 100 is a mobile phone as an example for description. Of course, other types of electronic devices 100 can also adopt a similar structure, which will not be described in detail below.

[0177] Understandable, Figure 1A and Figure 1B The electronic device 100 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1A and Figure 1B Due to limitations, electronic device 100 may also include, compared to Figure 1A and Figure 1B More or fewer parts.

[0178] In some embodiments, the electronic device 100 may include a camera module 10, a screen 20, and a housing 30. The screen 20 is used to display images, videos, etc. The screen 20 may include a light-transmitting panel 201 and a display screen 202. The light-transmitting panel 201 and the display screen 202 are stacked and fixedly connected. The light-transmitting panel 201 mainly serves to protect the display screen 202 from dust. The material of the light-transmitting panel 201 includes, but is not limited to, glass. The display screen 202 may be a flexible display screen or a rigid display screen. For example, the display screen 202 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0179] For example, the housing 30 is used to protect the internal electronic components of the electronic device 100. The housing 30 may include a cover plate 301, a frame 302, and a camera trim 303. The cover plate 301 is located on the side of the display screen 202 away from the light-transmitting panel 201, and is stacked with the light-transmitting panel 201 and the display screen 202. The frame 302 is fixed to the cover plate 301. For example, the frame 302 can be fixedly connected to the cover plate 301 by adhesive. The frame 302 may also be integrally formed with the cover plate 301, that is, the frame 302 and the cover plate 301 are a single structure. The frame 302 is located between the cover plate 301 and the light-transmitting panel 201. The light-transmitting panel 201 can be fixed to the frame 302 by adhesive. The light-transmitting panel 201, the cover plate 301, and the frame 302 form an internal accommodating space of the electronic device 100. This internal accommodating space houses the display screen 202. The cover plate 301 can be made of materials such as metal, plastic, or glass. It can be a single-material plate or a plate structure composed of multiple materials and assembled from multiple panels. The cover plate 301 has a mounting opening, and the camera decorative piece 303 covers and is fixed to the mounting opening.

[0180] For example, camera module 10 is used to capture photos / videos. For example, camera module 10 is mounted within housing 30, located within the internal accommodating space of electronic device 100. Camera module 10 can be used as a rear-facing camera. For example, the light-incident surface of camera module 10 faces camera trim 303. Camera trim 303 is used to protect camera module 10.

[0181] In some embodiments, the camera trim 303 protrudes from the side of the cover plate 301 away from the light-transmitting panel 201. This increases the mounting space for the camera module 10 in the thickness direction of the electronic device 100. In other embodiments, the camera trim 303 may be flush with the cover plate 301 or recessed into the internal accommodating space of the electronic device 100.

[0182] The camera decorative element 303 has a through hole 3031. The through hole 3031 allows light from the scene to enter the light-receiving surface of the camera module 10. In some other embodiments, the electronic device 100 may not include the camera decorative element 303. In this case, the cover plate 301 no longer has a mounting opening, but the through hole 3031 is provided on the cover plate 301, allowing light from the scene to enter the light-receiving surface of the camera module 10.

[0183] In some embodiments, the camera module 10 can also be used as a front-facing camera. For example, the light-incident surface of the camera module 10 faces the light-transmitting panel 201. The display screen 202 is provided with a light-path obstruction hole. This light-path obstruction hole allows light from the scene to pass through the light-transmitting panel 201 and then enter the light-incident surface of the camera module 10. In some embodiments, the electronic device 100 may also include one or more other camera modules (not shown in the figures), which are not strictly limited in this application.

[0184] In some embodiments, such as Figure 1B As shown, the electronic device 100 may further include a circuit board assembly 40 and an image processor 50. The circuit board assembly 40 and the image processor 50 are located within the internal accommodating space of the electronic device 100. The image processor 50 is fixed to and electrically connected to the circuit board assembly 40. The image processor 50 is communicatively connected to the camera module 10. The image processor 50 is used to acquire image data from the camera module 10 and process the image data. The communication connection between the camera module 10 and the image processor 50 may include data transmission via electrical connections such as wiring, or data transmission via coupling or other methods. It is understood that the camera module 10 and the image processor 50 may also be connected via other methods capable of data transmission.

[0185] In some embodiments, the electronic device 100 may further include an analog-to-digital converter (also known as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera module 10 and the image processor 50. The analog-to-digital converter is used to convert the signal generated by the camera module 10 into a digital image signal and transmit it to the image processor 50, whereby the image processor 50 processes the digital image signal and finally displays the image or video on the screen 20.

[0186] In some embodiments, the electronic device 100 may further include a memory (not shown in the figure), which is communicatively connected to the image processor 50. The image processor 50 processes the digital image signal and then transmits the image to the memory so that the image can be retrieved from the memory and displayed on the screen 20 at any time when it is needed to view the image. In some embodiments, the image processor 50 may also compress the processed digital image signal before storing it in the memory to save memory space.

[0187] In some other embodiments, the electronic device 100 may also not include the screen 20.

[0188] Understandable, Figure 1A and Figure 1B The installation position of the camera module 10 in the illustrated embodiment of the electronic device 100 is merely illustrative, and this application does not strictly limit the installation position of the camera module 10. In some other embodiments, the camera module 10 may also be installed in other locations on the electronic device 100, such as the upper middle or upper right corner of the back of the electronic device 100. In some other embodiments, the electronic device 100 may include a terminal body and an auxiliary component that can rotate, move, or be detached relative to the terminal body, and the camera module 10 may also be disposed on the auxiliary component.

[0189] Please refer to the following: Figures 2 to 4 , Figure 2 yes Figure 1A A schematic diagram of the camera module 10 in some embodiments of the electronic device 100 shown; Figure 3 yes Figure 2 A schematic diagram of the optical lens 1 in the camera module 10 in various states in some embodiments; Figure 4 yes Figure 3 The diagram shows the optical path structure of the optical lens 1 in various states in some embodiments of the camera module 10 shown.

[0190] In some embodiments, the camera module 10 may include an optical lens 1, an image sensor 2, and a filter 3. The photosensitive element is located on the image side of the optical lens 1. The camera module 10 may include a circuit board (not shown), and the image sensor 2 may be fixed to the circuit board. The filter 3 may be located between the optical lens 1 and the image sensor 2.

[0191] For example, the working principle of the camera module 10 is as follows: the light reflected from the subject passes through the optical lens 1 to generate an optical image, which is projected onto the photosensitive surface (also called the image surface) of the image sensor 2. The image sensor 2 converts the optical image into an electrical signal, i.e., an analog image signal, and transmits it to the analog-to-digital converter, so that the analog-to-digital converter can convert it into a digital image signal for the image processor 50.

[0192] Image sensor 2 (also known as a photosensitive element) is a semiconductor chip containing hundreds of thousands to millions of photodiodes on its surface. When illuminated, these photodiodes generate electrical charges. Image sensor 2 can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) device. CCDs are made using a highly sensitive semiconductor material that converts light into electrical charges. They consist of many photosensitive units, typically measured in megapixels. When light illuminates the surface of a CCD, each photosensitive unit reflects a charge onto the component. The signals generated by all the photosensitive units are combined to form a complete image. CMOS devices primarily utilize semiconductors made of silicon and germanium, allowing N-type (negative) and P-type (positive) semiconductors to coexist. The current generated by these complementary effects can be recorded and interpreted by the processing chip as an image.

[0193] Among them, the optical lens 1 mainly uses the refraction principle of the lens to form an image, that is, the light of the scene passes through the optical lens 1 and forms a clear image on the focal plane, and the image of the scene is recorded by the image sensor 2 located on the focal plane.

[0194] The filter 3 is used to filter out unwanted wavelengths of light, preventing the image sensor 2 from producing false colors or ripples, thereby improving its effective resolution and color reproduction. For example, the filter 3 can be an infrared filter 3. In this embodiment, the filter 3 is a separate component. In other embodiments, the filter 3 may be omitted, and filtering may be achieved by surface treatment or material treatment of at least one optical element of the optical lens 1. This application does not strictly limit the specific embodiments of the structure or component used to achieve filtering.

[0195] The optical lens 1 can be a vertical lens or a periscope lens. This embodiment describes the optical lens 1 as a periscope lens. When the optical lens 1 is a periscope lens, it can be better suited for use in thin electronic devices 100.

[0196] In some embodiments, the optical lens 1 may include a first fixed optical element 11, a second fixed optical element 12, a first zoom optical element 13, and a second zoom optical element 14, all located on the image side of the first fixed optical element 11. The first fixed optical element 11 is used to change the propagation direction of the optical axis from a first direction Z to a second direction X, where the first direction Z is different from the second direction X. In some embodiments, the first direction Z may be perpendicular to the second direction X.

[0197] For example, during the zooming process, the first fixed optical element 11 and the second fixed optical element 12 are fixed lens groups. The first zoom optical element 13 and the second zoom optical element 14 can move along the second direction X. The first zoom optical element 13 can also be used to achieve zooming, or the second zoom optical element 14 can also be used to achieve focusing.

[0198] Among them, the field of view (FOV) of optical lens 1 can be less than 40°. In other words, optical lens 1 is a telephoto lens, so that optical lens 1 can have a larger focal length adjustment range, which is conducive to achieving a larger focal length.

[0199] In this embodiment, the optical lens 1 can achieve continuous optical zoom between the telephoto end and the wide-angle end. The field of view (FOV) at the telephoto end can be less than 20°. For example, the FOV at the telephoto end can be, but is not limited to, 5°, 7°, 9°, 11°, 13°, 15°, 17°, 19°, or other values ​​less than 20°. The field of view (FOV) at the wide-angle end can be greater than 20° and less than 40°. For example, the FOV at the wide-angle end can be, but is not limited to, 21°, 23°, 25°, 27°, 29°, 31°, 33°, 35°, 37°, 39°, or other values ​​greater than 20° and less than 40°.

[0200] The first zoom optical element 13 may have a first range of motion, and the second zoom optical element 14 may have a second range of motion. By moving the first zoom optical element 13 within the first range of motion and the second zoom optical element 14 within the second range of motion, various states of the optical lens 1 can be changed. For example, as... Figure 3The optical lens 1 shown is divided into three states from top to bottom: the first state, the second state, and the third state. The dashed lines between the different states represent changes in the position of the corresponding optical elements. The desired effect can be achieved by moving the first zoom optical element 13 and the second zoom optical element 14, respectively. Figure 3 The state change is shown. It should be noted that when optical lens 1 also includes other zoomable optical elements, such as... Figure 3 The third zoom optical element 15 shown can also participate in the state change of the optical lens 1 by moving.

[0201] In this embodiment, the field of view (FOV) 1 of the optical lens 1 in the first state can be within the range of 24° to 35°. For example, FOV 1 can be, but is not limited to, 24°, 24.83°, 26°, 27°, 28°, 29°, 24.83°, 30.41°, 32°, 33°, 34°, 35°, or other values ​​between 24° and 35°. In this embodiment, since the optical lens 1 can have a large field of view, the optical lens 1 in the first state can also be referred to as the wide-angle end.

[0202] In this embodiment, the field of view (FOV) 3 of the optical lens 1 in the third state can be within the range of 12° to 16°. For example, FOV 3 can be, but is not limited to, 12°, 12.52°, 13°, 13.5°, 14°, 14.5°, 15°, 15.5°, 16°, or other values ​​between 12° and 16°. In this embodiment, since the optical lens 1 can have a small field of view, the optical lens 1 in the third state can also be referred to as the telephoto end.

[0203] In this embodiment, the field of view (FOV2) of the optical lens 1 in the second state can be within the range of 19° to 25°. For example, FOV2 can be, but is not limited to, 19°, 19.87°, 20°, 20.5°, 21°, 21.5°, 22°, 22.5°, 23°, 23.45°, 24°, 24.5°, 25°, or other values ​​between 19° and 25°. In this embodiment, the field of view (FOV2) of the optical lens 1 is located between FOV1 and FOV3, and the second state of the optical lens 1 can also be referred to as an intermediate state. The intermediate state is a state in the process of switching between the wide-angle end and the telephoto end, and the relative positions between the various optical elements are not limited.

[0204] It should be noted that the optical lens 1 can also switch to other states by moving the first zoom optical element 13 and the second zoom optical element 14. Figure 2 and Figure 3 This is for illustrative purposes only and does not limit the states that the optical lens 1 can achieve.

[0205] The first zoom optical element 13 may include one or more lenses.

[0206] The second zoom optical element 14 may include one or more lenses.

[0207] Taking mobile phones as an example, high-magnification optical zoom in mobile phones is usually achieved through "jump-like" zoom, using two to three lenses with different focal lengths, combined with algorithm-based digital zoom to achieve hybrid optical zoom. This results in poor image quality due to algorithm-based digital zoom between different focal lengths, severely impacting the shooting experience. However, in this embodiment, by moving the first zoom optical element 13 and the second zoom optical element 14, continuous zooming of the optical lens 1 between different focal lengths can be achieved. Compared to digital zoom, this results in better image quality and eliminates the need for multiple lenses, facilitating the miniaturization of the camera module 10. For example, this embodiment can achieve stepless adjustment of optical magnification between 3x and 5x, or between 3x and 8x, through the movement of the first zoom optical element 13 and the second zoom optical element 14. This allows for smoother adjustment of the optical lens 1 between different optical magnifications, achieving stepless adjustment and improving the shooting experience.

[0208] For example, the first fixed optical element 11 can be of positive optical power. In this embodiment, the first fixed optical element 11 is of positive optical power so that it has the ability to focus light, which helps to increase the amount of light entering the first fixed optical element 11, thereby increasing the amount of light entering the entire optical lens 1 and improving the imaging quality of the camera module 10. In addition, having a positive optical power for the first fixed optical element 11 also helps to shorten the overall length of the camera module 10, thus facilitating the miniaturization design of the camera module 10.

[0209] The first fixed optical element 11 may include one or more lenses.

[0210] For example, some or all of the lenses in the second fixed optical element 12 can be image stabilization optical element 121. During image stabilization of the optical lens 1, the image stabilization optical element 121 can move along the first direction Z and / or the third direction Y to achieve image stabilization. The third direction Y is different from both the first direction Z and the second direction X. In some embodiments, the third direction Y can be perpendicular to the first direction Z and perpendicular to the second direction X.

[0211] In this embodiment, image stabilization is achieved by driving the second fixed optical element 12 to move, allowing different optical elements to perform image stabilization and zooming respectively. This facilitates the staggered arrangement of the image stabilization drive mechanism and the zoom drive mechanism, thereby promoting miniaturization. Furthermore, since the image stabilization structure is not located in the first fixed optical element 11, the size of the reflective structure in the first fixed optical element 11 can be avoided, thus preventing the size of the first fixed optical element 11 from becoming too large, which in turn facilitates the overall miniaturization design of the camera module 10.

[0212] Therefore, the optical lens 1 of the present application embodiment can achieve continuous zoom and is conducive to miniaturization.

[0213] The second optical element G2 may include one or more lenses.

[0214] In some other embodiments, the image side of the first fixed optical element 11 may further include one or more optical elements. In some examples, the one or more optical elements may be a fixed lens group that does not participate in the zooming and focusing of the optical lens 1, nor in the image stabilization of the optical lens 1. In other examples, the one or more optical elements may move along the second direction X to participate in the zooming or focusing of the optical lens 1. It should be noted that the number of optical elements in the optical lens 1 is not limited in the embodiments of this application. The optical lens 1 may include four optical elements, five optical elements, or more optical elements, wherein each optical element may include one or more lenses.

[0215] In some embodiments, the first fixed optical element 11 may include a first lens group 111 and an optical path reversing element 112. The first lens group 111 is located on the object side of the optical path reversing element 112, and the first lens group 111 may have positive optical power. The object side of the first lens group 111 is the incident surface 1111 of the first fixed optical element 11. The optical path reversing element 112 may have a reflecting surface 1121, which is used to change the propagation direction of the optical axis from a first direction Z to a second direction X.

[0216] In this embodiment, the first fixed optical element 11 has a positive optical power, which enables the first fixed optical element 11 to have a light-gathering effect, so that as much external light as possible enters the optical path deflection element 112, thereby increasing the light intake of the entire first fixed optical element 11, which is beneficial to increasing the light intake of subsequent optical elements.

[0217] For example, the incident surface 1111 can be spherical to reduce manufacturing difficulty. In other embodiments, the incident surface 1111 can also be aspherical.

[0218] For example, the first lens group 111 may include one or more lenses.

[0219] The first lens group 111 may include one or two lenses with positive optical power to improve the light-gathering ability of the first lens group 111, thereby improving the amount of light entering the first fixed optical element 11.

[0220] In some examples, the optical path reversing element 112 can be a prism, and the image-side surface of the first lens group 111 can be fixed to the object-side surface of the optical path reversing element 112. The image-side surface of the optical path reversing element 112 is the exit surface 1122 of the first fixed optical element 11. The reflecting surface 1121 is part of the prism.

[0221] In this embodiment, the use of a prism facilitates the fixed installation of the first lens group 111 and the optical path folding element 112, thereby improving the overall stability of the first fixed optical element 11.

[0222] The reflecting surface 1121 can be planar to ensure good processability. In other embodiments, the reflecting surface 1121 can also correct aberrations such as astigmatism when reflecting light, thereby further improving image quality or reducing volume. For example, the reflecting surface 1121 can also be spherical, cylindrical, or freeform. A spherical surface can be convex or concave. A cylindrical surface has curvature in one direction and extends linearly in another. Exemplarily, the reflecting surface 1121 can also be a total reflection surface 1121, or it can be provided with a high-reflection coating (e.g., deposited metal) to improve reflection efficiency, so that the light beam is completely or nearly completely reflected before entering subsequent optical elements.

[0223] The first lens group 111 and the optical path reversing element 112 can be glued together to improve the connection stability between them, thereby enhancing the overall stability of the first fixed optical element 11 and facilitating its installation. When the first lens group 111 and the optical path reversing element 112 are glued together, the first fixed optical element 11 becomes a single-piece structure. When assembled with other optical elements, internal alignment is no longer required, reducing installation difficulty, improving installation efficiency, and enhancing the optical performance of the first fixed optical element 11. In other embodiments, the connection between the first lens group 111 and the optical path reversing element 112 can also be achieved using an imprinting process.

[0224] The first lens group 111 and the optical path folding element 112 can also be an integral structure. In other words, the first fixed optical element 11 is an irregularly shaped prism with an integral structure. The first lens group 111 and the optical path folding element 112 are different parts of the first fixed optical element 11, which is beneficial to improving the structural stability of the first fixed optical element 11 and improving the installation efficiency of the optical lens 1.

[0225] The first lens group 111 and the optical path deflection element 112 may both be made of glass, or they may be made of different materials. This application does not impose strict limitations on this.

[0226] In some other embodiments, there may also be a gap between the object-side surfaces of the first lens group 111 and the optical path reversing element 112. In this case, the first lens group 111 can be fixed to the optical path reversing element 112 by means of a structural component such as a lens barrel.

[0227] In other examples, the optical path reversing element 112 can also be a reflector, in which case the mirror surface of the reflector forms the reflecting surface 1121. The first lens group 111 can be fixed to the optical path reversing element 112 by means of a structure such as a lens barrel, so that the relative position of the incident surface 1111 and the reflecting surface 1121 is fixed. In this case, the reflecting surface 1121 is also the exit surface 1122 of the first fixed optical element 11.

[0228] In some embodiments, the focal length Fg1 of the first fixed optical element 11 and the focal length Fo of the image stabilization optical element 121 can satisfy: Fg1>|Fo|.

[0229] In this embodiment, the focal length Fo of the image stabilization optical element 121 satisfies the above-mentioned relationship, so that the optical power of the image stabilization optical element 121 can be set higher, thereby improving the light bending capability of the image stabilization optical element 121 and improving the imaging quality of the camera module 10. In addition, it is possible to reduce the amount of movement of the image stabilization optical element 121 while maintaining high optical performance, which is beneficial to achieving image stabilization.

[0230] In some embodiments, the combined focal length Ft of the first fixed optical element 11 to the image-stabilizing optical element 121 and the focal length Fo of the image-stabilizing optical element 121 can satisfy: 0.40 < |Ft| / |Fo| < 5.00. For example, the value of |Ft| / |Fo| can be, but is not limited to, 0.5, or 0.7, or 1.2, or 1.3, or 1.5, or 1.86, or 2.1, or 2.3, or 2.64, or 3.1, or 3.45, or 3.7, or 4.2, or 4.5, or 4.9, or other values ​​between 0.40 and 5.00.

[0231] In this embodiment, by setting the focal length Fo of the image stabilization optical element 121 to satisfy the above relationship, the amount of movement of the image stabilization optical element 121 can be suppressed while maintaining the optical performance of the image stabilization element, which is beneficial to achieving image stabilization.

[0232] In some embodiments, the thickness Tg1 of the first fixed optical element 11 along the optical axis and the thickness To of the image stabilizing optical element 121 along the optical axis can satisfy: 0.05 < |To| / |Tg1| < 1.00. For example, the value of |To| / |Tg1| can be, but is not limited to, 0.06, 0.08, 0.14, 0.19, 0.20, 0.51, 0.6, 0.7, 0.8, 0.9, 0.95, 0.99, or other values ​​between 0.05 and 1.00.

[0233] In this embodiment, the thickness To of the image stabilization optical element 121 along the optical axis satisfies the above-mentioned relationship, which can reduce the weight of the image stabilization optical element 121 while maintaining its optical performance. This is beneficial for reducing the driving force required for image stabilization, thereby achieving energy saving and miniaturization.

[0234] It should be noted that the thickness Tg1 of the first fixed optical element 11 along the optical axis is the sum of the first part length Tg1r and the second part length Tgr2. The length of the first fixed optical element 11 along the optical axis in the first direction Z is the first part length Tg1r, that is, the length from the incident surface 1111 along the optical axis in the first direction Z to the reflecting surface 1121 is the first part length Tg1r. The length of the first optical element G1 along the optical axis in the second direction X is the second part length Tgr2, that is, the length from the reflecting surface 1121 along the optical axis in the second direction X to the exit surface 1122 is the second part length Tgr2.

[0235] The thickness Tg1 of the first fixed optical element 11 along the optical axis and the thickness To of the image stabilization optical element 121 along the optical axis can satisfy: 0.1 < |To| / |Tg1| < 0.6. For example, the value of |To| / |Tg1| can be, but is not limited to, 0.11, 0.12, 0.14, 0.19, 0.20, 0.3, 0.4, 0.51, 0.55, 0.59, or other values ​​between 0.1 and 0.6.

[0236] In this embodiment, the thickness To of the image stabilization optical element 121 along the optical axis satisfies the above-mentioned relationship, which can further reduce the weight of the image stabilization optical element 121 while maintaining its optical performance. This is beneficial to reducing the driving force required for image stabilization, thereby further achieving energy saving and miniaturization.

[0237] In some embodiments, the first zoom optical element 13 can be positive optical power and the second zoom optical element 14 can be negative optical power; or, the first zoom optical element 13 can be negative optical power and the second zoom optical element 14 can be positive optical power.

[0238] In this embodiment, through the combination of positive and negative optical powers, it is beneficial for the first zoom optical element 13 and the second zoom optical element 14 to achieve a continuous zoom function, and it is also beneficial to eliminate aberrations to improve the imaging quality.

[0239] In some embodiments, the distance Tg1r along the optical axis between the incident surface 1111 and the reflection surface 1121 and the thickness Tgo of the second fixed optical element 12 along the optical axis may satisfy: 0.5 < Tgo / Tg1r < 2.0. For example, the value of Tgo / Tg1r may be, but is not limited to, 0.52, or 0.55, or 0.62, or 0.71, or 0.88, or 0.92, or 0.98, or 1.07, or 1.2, or 1.4, or 1.6, or 1.8, or 1.9, or 1.95, or 1.99, or other values between 0.5 and 2.0.

[0240] In this embodiment, when the thickness Tgo of the second fixed optical element 12 along the optical axis satisfies the above relationship, while maintaining the optical performance of the anti-shake optical element 121, the height of the first fixed optical element 11 (i.e., the dimension in the first direction Z) can be reduced, thereby reducing the overall height of the optical lens 1, which is beneficial to the miniaturized design of the optical lens 1.

[0241] In some embodiments, the first fixed optical element 11, the second fixed optical element 12, the first zoom optical element 13, and the second zoom optical element 14 may be arranged in sequence from the object side to the image side. For the sake of convenience in description, in this embodiment, the first fixed optical element 11 may be referred to as the first optical element G1, the second fixed optical element 12 may be referred to as the second optical element G2, the first zoom optical element 13 may be referred to as the third optical element G3, and the second zoom optical element 14 may be referred to as the fourth optical element G4.

[0242] In this embodiment, by setting at least part of the lenses in the second optical element G2 for anti-shake, so that a moving lens group for zooming (such as the third optical element G3 and the fourth optical element G4 in this embodiment) can be arranged between the second optical element G2 and the image sensor 2, the interference between the mechanism for anti-shake driving and the mechanism for zoom driving can be reduced, thereby making the design of the moving lens group simpler, which is beneficial to the simplified design of the optical lens 1 and the imaging module 10.

[0243] Exemplarily, during the zooming process of the optical lens 1, the change in the focal length Fsys of the optical lens 1 may satisfy: 20 mm ≤ Fsys ≤ 50 mm, so that the optical lens 1 is a telephoto lens. For example, the value of Fsys may be 20 mm, or 25 mm, or 30 mm, or 35 mm, or 40 mm, or 45 mm, or 50 mm, or other values between 20 mm and 50 mm.

[0244] For example, the focal length Fg1 of the first optical element G1 can satisfy: 30mm ≤ Fg1 ≤ 130mm. For example, the value of Fg1 can be, but is not limited to, 30mm, or 40mm, or 50mm, or 60mm, or 70mm, or 80mm, or 90mm, or 100mm, or 110mm, or 120mm, or 130mm, or other values ​​between 30mm and 130mm.

[0245] For example, the absolute value of the focal length Fg2 of the second optical element G2 and the absolute value of the focal length Fg3 of the third optical element G3 can satisfy: |Fg2|>|Fg3|.

[0246] In this embodiment, the absolute value of the focal length Fg2 of the second optical element G2 and the absolute value of the focal length Fg3 of the third optical element G3 satisfy the above-mentioned relationship, which is beneficial to improve the optical performance of the optical lens 1 while realizing continuous zoom of the optical lens 1.

[0247] The absolute value of the focal length Fg2 of the second optical element G2 and the absolute value of the focal length Fg3 of the third optical element G3 can satisfy: 1.00 < |Fg2 / Fg3| < 3.00. For example, the value of |Fg2 / Fg3| can be, but is not limited to, 1.05, 1.15, 1.25, 1.35, 1.45, 1.55, 1.75, 1.95, 2.05, 2.35, 2.45, 2.55, 2.65, 2.75, 2.85, 2.99, or any other value between 1.00 and 3.00.

[0248] In this embodiment, the absolute value of the focal length Fg2 of the second optical element G2 and the absolute value of the focal length Fg3 of the third optical element G3 satisfy the above-mentioned relationship, which is beneficial to further improve the optical performance of the optical lens 1 while realizing continuous zoom of the optical lens 1.

[0249] The focal length Fg2 of the second optical element G2 can satisfy the following condition: -30mm ≤ Fg2 ≤ -15mm. For example, the value of Fg2 can be, but is not limited to, -30mm, -28mm, -26mm, -24mm, -22mm, -20mm, -18mm, -17mm, -16mm, -15mm, or other values ​​between -30mm and -15mm.

[0250] The focal length Fg3 of the third optical element G3 can satisfy: 10mm ≤ Fg3 ≤ 20mm. For example, the value of Fg3 can be, but is not limited to, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, or other values ​​between 10mm and 20mm.

[0251] The focal length Fg4 of the fourth optical element G4 can satisfy the following condition: -20mm ≤ Fg4 ≤ 35mm. For example, the value of Fg4 can be, but is not limited to, -20mm, -18mm, -16mm, -14mm, -13mm, -12mm, -10mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, or other values ​​between -20mm and 35mm.

[0252] For example, during the zooming process of optical lens 1, the distance Lg23 between the second optical element G2 and the third optical element G3 along the optical axis can vary within the range of 0.4 mm to 8.5 mm. For example, the value of Lg23 can be, but is not limited to, 0.4 mm, or 1 mm, or 2 mm, or 3 mm, or 4 mm, or 5 mm, or 6 mm, or 7 mm, or 8 mm, or 8.5 mm, or other values ​​between 0.4 mm and 8.5 mm.

[0253] For example, during the zooming process of optical lens 1, the distance Lg34 between the third optical element G3 and the fourth optical element G4 along the optical axis can vary within the range of 1mm to 13.5mm. For example, the value of Lg34 can be, but is not limited to, 1mm, or 2mm, or 3mm, or 4mm, or 5mm, or 6mm, or 7mm, or 8mm, or 9mm, or 10mm, or 11mm, or 12mm, or 13mm, or 13.5mm, or other values ​​between 1mm and 13.5mm.

[0254] In some embodiments, the optical lens 1 may further include a third zoom optical element 15, which may be located on the image side of the first fixed optical element 11. During zooming, the third zoom optical element 15 may move along the second direction X to achieve zooming.

[0255] In this embodiment, the third zoom optical element 15 works together with the first zoom optical element 13 and the second zoom optical element 14 to achieve more flexible and precise zooming, thereby facilitating continuous zooming.

[0256] For example, the third zoom optical element 15 can be located on the image side of the fourth optical element G4. For ease of description, in this embodiment, the third zoom optical element 15 can be referred to as the fifth optical element G5. The focal length Fg5 of the fifth optical element G5 can satisfy: -110mm ≤ Fg5 ≤ -14mm. For example, the value of Fg5 can be, but is not limited to, -110mm, -100mm, -90mm, -80mm, -70mm, -60mm, -50mm, -40mm, -30mm, -20mm, -14mm, or other values ​​between -110mm and -14mm.

[0257] The distance Lg45 between the fourth optical element G4 and the fifth optical element G5 along the optical axis can vary from 2 mm to 5.5 mm. For example, the value of Lg45 can be, but is not limited to, 2 mm, 2.4 mm, 2.8 mm, 3.2 mm, 3.6 mm, 4 mm, 4.4 mm, 4.8 mm, 5.2 mm, 5.5 mm, or other values ​​between 2 mm and 5.5 mm.

[0258] For example, at least one of the third optical element G3, the fourth optical element G4 and the fifth optical element G5 can be positive optical power and at least one can be negative optical power.

[0259] In this embodiment, the combination of optical elements with positive and negative optical power is beneficial for achieving continuous zoom function and for eliminating aberrations, thereby improving image quality.

[0260] Please continue reading. Figure 2 and Figure 3 In some embodiments, the optical surface of at least one lens of the optical lens 1 can be an aspherical surface. The aspherical optical surface has different optical powers from the paraxial region to the outer field of view, thereby achieving a more uniform image quality. And / or, the optical surface of at least one lens of the optical lens 1 can be a freeform surface to correct aberrations. Wherein, an aspherical surface is a surface that is rotationally symmetrical about the optical axis; a freeform surface may have no axis of symmetry, or it may be symmetrical along a certain direction, or symmetrical along two directions.

[0261] In some embodiments, the multiple lenses of the optical lens 1 can be assembled using an active alignment (AA) process to ensure assembly accuracy.

[0262] In some embodiments, the optical lens 1 may further include an aperture stop. Exemplarily, the aperture stop may be mounted on the second optical element G2. In this case, the aperture adjustment effect of the aperture stop is better, further improving the imaging quality of the optical lens 1. For example, the aperture stop may be mounted on the object side of the second optical element G2. In other embodiments, the aperture stop may also be mounted at other locations on the optical lens 1; this application does not strictly limit this.

[0263] The aperture stop can be a spacer structure or a variable fan-blade structure; alternatively, the aperture stop can be achieved through a surface coating process, such as forming the aperture stop by spraying a light-shielding material onto the lens. The position of the aperture stop can be fixed or variable. For example, the position of the aperture stop can be variable, adjusting its position according to focusing conditions to be located between different lenses.

[0264] In some embodiments, at least one lens of the optical lens 1 can employ a non-circular shape technique to reduce the size of the optical lens 1. For example, at least one lens in the second optical element G2 or at least one lens in the third optical element G3 can have a notch to reduce the height of the lens. The notch can be implemented using an I-CUT process. By providing a notch to reduce the height of the lens on at least one lens in the second optical element G2 or at least one lens in the third optical element G3, the size of the optical lens 1 in the height direction can be effectively reduced, making the optical lens 1 more suitable for miniaturized electronic devices 100 and increasing the applicability of the optical lens 1. Furthermore, since the lens height is reduced by the notch, the lens can have a larger light-transmitting aperture, thereby increasing the light transmission of the optical lens 1 and resulting in better image quality. Alternatively, non-circular shapes can be used on the lens's structural support components such as the lens barrel and spacers to reduce the size of the optical lens 1.

[0265] In some embodiments, the peripheral surface or support surface of at least one lens of the optical lens 1 may be blackened or roughened to eliminate stray light and improve image quality. Blackening may involve coating or plating with a matte material such as black ink, or applying a film. Roughening primarily increases surface roughness. Of course, in other embodiments, the optical lens 1 may also eliminate stray light in other ways; this application does not strictly limit this approach.

[0266] In some embodiments, the materials used for different lenses of the optical lens 1 may have different temperature characteristics, such as glass and plastic respectively, to reduce the influence of ambient temperature.

[0267] In some embodiments, the optical surface of at least one lens of the optical lens 1 can form a diffraction structure (not shown in the figure). In this embodiment, by reasonably setting the diffraction structure, chromatic aberration can be reduced, and the size of the optical lens 1 can also be reduced.

[0268] In some embodiments, the optical lens 1 may further include a liquid lens (not shown in the figure). For example, the liquid lens may be located between the first optical element G1 and the second optical element G2. In this embodiment, the focusing effect can be enhanced by the liquid lens to achieve super macro photography. The liquid lens is a structural component that uses liquid as a lens and changes the focal length by altering the curvature of the liquid.

[0269] The following presents the results, combining data and simulation findings. Figure 2 The camera module 10 shown is a specific embodiment in one possible scheme.

[0270] In some embodiments, the camera module 10 includes an optical lens 1, a filter 3, and an image sensor 2 arranged from the object side to the image side. The optical lens 1 includes a first optical element G1 (first fixed optical element 11), a second optical element G2 (second fixed optical element 12), a third optical element G3 (first zoom optical element 13), a fourth optical element G4 (second zoom optical element 14), and a fifth optical element G5 (third zoom optical element 15) arranged from the object side to the image side.

[0271] The first optical element G1 has positive optical power. The first optical element G1 includes a first lens group 111 and an optical path reversing element 112 arranged from the object side to the image side. The first lens group 111 includes a first lens L1, the object side of which forms the incident surface 1111 of the first optical element G1. The optical path reversing element 112 includes a reflecting surface 1121, which is used to change the propagation direction of the optical axis. The optical path reversing element 112 is a prism, and the object side of the optical path reversing element 112 forms the exit surface 1122 of the first optical element G1.

[0272] The second optical element G2 has negative optical power and includes a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6 arranged from the object side to the image side. The second lens L2 and the third lens L3 form an image stabilization optical element 121, and the object side of the fourth lens L4 is provided with an aperture stop.

[0273] The third optical element G3 has positive optical power and includes a seventh lens L7, an eighth lens L8, and a ninth lens L9 arranged from the object side to the image side.

[0274] The fourth optical element G4 has negative optical power and includes the tenth lens L10.

[0275] The fifth optical element G5 has negative optical power and includes an eleventh lens L11 and a twelfth lens L12 arranged from the object side to the image side.

[0282] The aspherical surface of optical lens 1 in Table 1a can be limited by, but is not limited to, the following aspherical curve equations:

[0283]

[0284] Where z is a point on the aspherical surface at a distance r from the optical axis, and its relative distance to the tangent plane at the intersection point on the optical axis of the aspherical surface; r is the perpendicular distance between a point on the aspherical curve and the optical axis; c is the curvature; k is the conic coefficient, which is 0; αi is the i-th order aspherical coefficient, which can be found in Table 1b.

[0285] Please refer to Table 1c, which is... Figure 2The basic parameters of the camera module 10 shown in one possible embodiment are as follows.

[0288] During the zooming process of the camera module 10, the first fixed optical element 11 and the second optical element G2 remain fixed, while the third optical element G3, the fourth optical element G4, and the fifth optical element G5 move along the optical axis to achieve the switching between different shooting states. Specifically, please refer to Table 1d, which is... Figure 3 The camera module 10 shown has basic parameters for the optical lens 1 in different states in one possible embodiment. Specifically, when the optical lens 1 is in different states, some of its focal length (mm), F#, image height (mm), field of view, Lg23 (mm), Lg34 (mm), Lg45 (mm), and Lg5s (mm) exhibit different values.

[0289] Table 1d

[0290] illustrate First state Second state Third state focal length 22.91 30.95 45.74 F# 2.60 3.31 4.40 Like Gao 6.23 6.23 6.23 Field of view 30.41° 22.75° 15.50° Lg23 7.490 4.827 0.492 Lg34 5.607 4.270 3.794 Lg45 2.718 2.840 1.943 Lg5s 0.991 4.871 10.578

[0291] In this embodiment, during the zooming process of the optical lens 1, the movement range of the third optical element G3 is: the distance Lg3s from the image sensor 2 varies from 9.32mm to 26.753mm; the movement range of the fourth optical element G4 is: the distance Lg4s from the image sensor 2 varies from 3.71mm to 13.093mm; and the movement range of the fifth optical element G5 is: the distance Lg5s from the image sensor 2 varies from 0.99mm to 10.58mm.

[0292] Specifically, the distance Lg23 between the second optical element G2 and the third optical element G3 varies from 7.49 mm to 0.49 mm. The distance Lg34 between the third optical element G3 and the fourth optical element G4 varies from 13.226 mm to 3.79 mm. The distance Lg45 between the fourth optical element G4 and the fifth optical element G5 varies from 5.66 mm to 1.94 mm.

[0293] Please refer to the following: Figures 5 to 7 , Figure 5 yes Figure 3 The axial chromatic aberration curve of the optical lens 1 in the first state in the camera module 10 shown in one possible embodiment; Figure 6 yes Figure 3 The image astigmatism curve of the optical lens 1 in the camera module 10 in a first state in one possible embodiment is shown. Figure 7 yes Figure 3 The distortion curve of the optical lens 1 in the camera module 10 in a first state in one possible embodiment is shown.

[0294] It should be noted that, Figures 5 to 7 This is a simulation result diagram of optical lens 1 in its first state, with focus at infinity.

[0295] The axial chromatic aberration curve includes spherical aberration curves corresponding to different wavelengths of the system (the illustration includes 436nm, 588nm, and 658nm); its physical meaning is the deviation of light of the corresponding wavelength emitted in the 0-degree field of view from the ideal image point after passing through the optical system; its horizontal axis is the deviation value (mm) along the optical axis, and the vertical axis is the normalized coordinate at the pupil. Figure 5 The values ​​shown are all small, indicating that the on-axis aberrations (spherical aberration, chromatic aberration, etc.) of optical lens 1 are well corrected.

[0296] The astigmatism curve is used to illustrate the deviation between the beam convergence point and the ideal imaging plane under different fields of view. The horizontal axis represents the deviation value (mm) along the optical axis, and the vertical axis represents the corresponding field of view. When the value of a certain field of view is too large, the image quality of that field of view is poor or there are advanced aberrations. Figure 6 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0297] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 7 The offsets shown are all within 1.5%, which ensures that there is no obvious distortion in the image.

[0298] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the first state.

[0300] It should be noted that, Figures 8 to 10 This is a simulation result diagram of optical lens 1 in the second state, with focus at infinity.

[0301] The axial chromatic aberration curve includes spherical aberration curves corresponding to different wavelengths of the system (the illustration includes 436nm, 588nm, and 658nm); its physical meaning is the deviation of light of the corresponding wavelength emitted in the 0-degree field of view from the ideal image point after passing through the optical system; its horizontal axis is the deviation value (mm) along the optical axis, and the vertical axis is the normalized coordinate at the pupil. Figure 8 The values ​​shown are all small, indicating that the on-axis aberrations (spherical aberration, chromatic aberration, etc.) of optical lens 1 are well corrected.

[0302] The astigmatism curve is used to illustrate the deviation between the beam convergence point and the ideal imaging plane under different fields of view. The horizontal axis represents the deviation value (mm) along the optical axis, and the vertical axis represents the corresponding field of view. When the value of a certain field of view is too large, the image quality of that field of view is poor or there are advanced aberrations. Figure 9 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0303] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 10 The offsets shown are all within 2%, which ensures that there is no obvious distortion in the image.

Figure 30 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0361] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view.

[0400] It should be noted that, Figures 41 to 43 This is a simulation result diagram of optical lens 1 in its first state, with focus at infinity.

[0401] The axial chromatic aberration curve includes spherical aberration curves corresponding to different wavelengths of the system (the illustration includes 436nm, 588nm, and 658nm); its physical meaning is the deviation of light of the corresponding wavelength emitted in the 0-degree field of view from the ideal image point after passing through the optical system; its horizontal axis is the deviation value (mm) along the optical axis, and the vertical axis is the normalized coordinate at the pupil. Figure 41 The values ​​shown are all small, indicating that the on-axis aberrations (spherical aberration, chromatic aberration, etc.) of optical lens 1 are well corrected.

[0402] The astigmatism curve is used to illustrate the deviation between the beam convergence point and the ideal imaging plane under different fields of view. The horizontal axis represents the deviation value (mm) along the optical axis, and the vertical axis represents the corresponding field of view. When the value of a certain field of view is too large, the image quality of that field of view is poor or there are advanced aberrations. Figure 42 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0403] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 43 The offsets shown are all within 3.5%, which ensures that there is no obvious distortion in the image.

[0404] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the first state.

Figure 45 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0409] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 46 The offsets shown are all within 1.5%, which ensures that there is no obvious distortion in the image.

[0410] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the second state.

Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0415] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 49 The offsets shown are all within 2%, which ensures that there is no obvious distortion in the image.

[0416] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the third state.

[0456] Please refer to the following: Figures 59 to 61 , Figure 59 yes Figure 56 The axial chromatic aberration curve of the optical lens 1 in the first state in the camera module 10 shown in one possible embodiment; Figure 60 yes Figure 56 The image astigmatism curve of the optical lens 1 in the camera module 10 in a first state in one possible embodiment is shown.

[0457] It should be noted that, Figures 59 to 61 This is a simulation result diagram of optical lens 1 in its first state, with focus at infinity.

[0458] The axial chromatic aberration curve includes spherical aberration curves corresponding to different wavelengths of the system (the illustration includes 436nm, 588nm, and 658nm); its physical meaning is the deviation of light of the corresponding wavelength emitted in the 0-degree field of view from the ideal image point after passing through the optical system; its horizontal axis is the deviation value (mm) along the optical axis, and the vertical axis is the normalized coordinate at the pupil. Figure 59 The values ​​shown are all small, indicating that the on-axis aberrations (spherical aberration, chromatic aberration, etc.) of optical lens 1 are well corrected.

[0459] The astigmatism curve is used to illustrate the deviation between the beam convergence point and the ideal imaging plane under different fields of view. The horizontal axis represents the deviation value (mm) along the optical axis, and the vertical axis represents the corresponding field of view. When the value of a certain field of view is too large, the image quality of that field of view is poor or there are advanced aberrations. Figure 60 The field curvatures in both directions shown are small, indicating that the system has good depth of focus. Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0460] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 61 The offsets shown are all within 1%, which ensures that there is no obvious distortion in the image.

[0461] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the first state.

Here, tangential represents the tangential direction and is indicated by a solid line; sagittal represents the sagittal direction and is indicated by a dashed line.

[0466] The distortion diagram is used to characterize the relative deviation between the beam convergence point (actual image height) and the ideal image height in different fields of view. Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 64 The offsets shown are all within 3%, which ensures that there is no obvious distortion in the image.

[0467] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the second state.

Its horizontal axis represents the deviation (percentage), and the vertical axis represents the corresponding field of view. Figure 67 The offsets shown are all within 2.5%, which ensures that there is no obvious distortion in the image.

[0473] Therefore, it can be concluded that the optical lens 1 provided in the embodiments of this application has good on-axis aberration correction, good depth of focus, and no obvious distortion in the image display in the third state.
