Description

Technical Field

[0001] The present disclosure relates to an optical camera lens set, an imaging device and an electronic device, and in particular to an optical camera lens set and an imaging device suitable for an electronic device. Background Art

[0002] As semiconductor process technology becomes more advanced, the performance of electronic photosensitive elements has been improved, and pixels can reach smaller sizes. Therefore, optical lenses with high imaging quality have become an indispensable part.

[0003] As technology advances, the application scope of electronic devices equipped with optical lenses is becoming wider, and the requirements for optical lenses are becoming more diverse. Since it is difficult for existing optical lenses to strike a balance between the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, the present invention provides an optical lens with high imaging quality to meet the requirements.

[0004] Specifically, in recent years, electronic products have been demanding to be thinner and lighter, so traditional photographic lenses are difficult to meet the needs of high specifications and miniaturization at the same time, especially miniature lenses with large apertures or telephoto features. However, as the demand for optical zoom becomes more stringent (increasing the optical zoom ratio, etc.), the known previous telephoto lens technology is gradually unable to meet the demand (total length is too long, the aperture is too small, the quality is insufficient or it cannot be miniaturized), so different optical characteristics or configurations with optical axis turning are needed to solve the problem. Due to the thickness limit of electronic devices, some optical lenses will be cut in the lens barrel or lens to reduce the single-axis length, which helps to save module space. In addition, they can be matched with reflective elements to provide different light paths for the system, giving the lens more flexible use space to show the telephoto effect of long focal length. And through the grouping design of the lens group, according to the distance of the shooting object, the focal length of the lens group of the photography system is adjusted and the focus is completed by changing the spacing between each lens group, so as to achieve high imaging quality for both long-range and close-range shooting, which helps to improve the freedom of lens shooting. Summary of the invention

[0017] The present disclosure further provides an optical camera lens group, which includes three lens groups.

Each lens has an object-side surface facing the object side direction and an image-side surface facing the image side direction. The distance on the optical axis from the object to the object-side surface of the most object-side lens of the optical camera lens group is defined as the object distance. Preferably, during the transition of the object distance from infinity to macro, the optical camera lens group performs a moving focusing process to change from the first state to the second state.

When the object distance is infinity, the distance on the optical axis from the object-side surface of one of the most object-side lenses in the second lens group to the image-side surface of one of the most image-side lenses in the third lens group is DG2G3L. When the object distance is infinity, the distance on the optical axis from the image-side surface of one of the most image-side lenses to the imaging surface of the optical camera lens group is BLL. When the object distance is macro, the distance on the optical axis from the image-side surface of the most image-side lens to the imaging surface is BLS, and it preferably satisfies the following conditions:

[0018] 0.50 < TG1G2L / DG2G3L < 2.50;

[0019] 0.95 < BLL / BLS < 1.05; and

[0020] 0.08 < (TG1G2L - TG1G2S) / TG1G2L < 0.50.

[0021] The present disclosure provides an imaging device, which includes the foregoing optical camera lens group, an image stabilization module, and an electronic photosensitive element. The image stabilization module is disposed corresponding to the optical camera lens group, and the electronic photosensitive element is disposed on the imaging surface of the optical camera lens group.

[0022] The present disclosure provides an electronic device, which includes the foregoing imaging device.

[0023] The optical camera lens group, imaging device and electronic device provided by the present disclosure can be cut in part of the lens barrel or lens to reduce the single-axis length in response to the thickness limit of the electronic device, which helps to save module space. In addition, it can also be matched with a reflective element to provide different light paths for the entire system, giving the lens more flexible use space to display the telephoto effect of a long focal length. In addition, by designing the lens group in groups, the focal length of the optical camera lens group can be adjusted and the focus can be completed by changing the spacing between each lens group according to the distance (object distance) of the shooting object (subject), so as to achieve high imaging quality in both long-range and close-range shooting, which helps to improve the freedom of lens shooting.

[0024] When T12L / Dr3r14L meets the above conditions, the ratio of the distance between the first lens and the second lens to the distance from the object side surface of the second lens to the image side surface of the seventh lens can be adjusted to help provide sufficient space for configuring the reflective element and maintain the optimal spatial configuration of the lens group.

[0025] When Dr3-10L / Dr11-14L meets the above conditions, the length of the mobile optical camera lens group on the optical axis and the length of the image side optical camera lens group on the optical axis can be adjusted to help balance the spatial configuration of the lens to reduce the system sensitivity during mobile focusing.

[0026] When |f4 / f5| satisfies the above conditions, the ratio of the refractive power strengths of the fourth lens element and the fifth lens element can be adjusted to effectively control the direction of the light path, thereby helping to reduce the incident angle of the light on the imaging surface.

[0027] When TLL / BLL meets the above conditions, the appropriate back focal length can be adjusted to facilitate optical path folding.

[0028] When V5 / N5 meets the above conditions, the material configuration of the fifth lens can be adjusted to help correct system chromatic aberration when shooting at multiple object distances, prevent image overlap, and thus improve image quality.

[0029] When TG1G2L / DG2G3L meets the above conditions, the ratio of the distance between the first lens group and the second lens group to the total length of the second lens group and the third lens group can be adjusted to provide enough space for configuring the reflective element and maintain the optimal spatial configuration of the lens group.

[0030] When BLL / BLS meets the above conditions, it helps to reduce excessive changes in the incident angle of light on the imaging surface during mobile focusing.

[0031] When (TG1G2L-TG1G2S) / TG1G2L satisfies the above conditions, increasing the movement amount of the second lens group during the mobile focusing process helps to shoot objects at a smaller object distance and improve the shooting angle of view.

Among them, the three lens groups may include seven lenses, and the seven lenses are sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens along the optical path from the object side to the image side. Among them, the seven lenses respectively have an object side surface facing the object side direction and an image side surface facing the image side direction. In one embodiment, the first lens group may include a first lens, the second lens group may include at least a second lens, a third lens and a fourth lens, and the third lens group may include at least a sixth lens and a seventh lens. In another embodiment, the first lens group may include a first lens, the second lens group may include a second lens, a third lens, a fourth lens, and a fifth lens, and the third lens group may include a sixth lens and a seventh lens. In yet another embodiment, the first lens group may include a first lens, the second lens group may include a second lens, a third lens, and a fourth lens, and the third lens group may include a fifth lens, a sixth lens, and a seventh lens. Thus, the design of seven lenses and a grouping method helps to achieve a balance between volume and image quality and realize mobile focusing, and in the process of mobile focusing, high imaging quality can be achieved for shooting at various object distances. When the total number of lenses in the optical camera lens group is seven, the first lens can be called the most object side lens closest to the object side, and the seventh lens can also be called the most image side lens closest to the image side.

[0169] According to the optical camera lens set disclosed in the present invention, the distance from the object to the object side surface of the most object side lens of the optical camera lens set on the optical axis can be defined as the object distance of the optical camera lens set. The optical camera lens set has a first state corresponding to the infinite object distance and a second state corresponding to the micro object distance, wherein the first state refers to the state of the optical camera lens set when the object is located at infinity, and the second state refers to the state of the optical camera lens set when the object is located at macro. During the period when the object distance changes from infinity to macro, the optical camera lens set performs a moving focus process to change from the first state to the second state. Conversely, during the period when the object distance changes from macro to infinity, the optical camera lens set can perform a moving focus process to change from the second state to the first state. Please refer to Figure 1 , are schematic diagrams showing an optical camera lens assembly in an imaging device according to a first embodiment of the present disclosure in a first state (infinite object distance) and in a second state (micro object distance), wherein Figure 1 The upper part of is a schematic diagram of the optical camera lens assembly in the first state, and Figure 1The lower half of is a schematic diagram of the optical camera lens group in the second state. Among them, the second lens group moves toward the object side along the optical axis relative to the first lens group and the third lens group during the mobile focusing process. Thereby, it is helpful to achieve the effect of close-up and simplify the complexity of the optical design and mechanism. The lenses in each of the three lens groups do not move relative to each other during the mobile focusing process. Thereby, the complexity of the mechanism can be simplified. In the present disclosure, the micro object distance or macro distance refers to the object being obviously close to the optical camera lens group relative to infinity. Among them, the micro object distance or macro distance refers to the distance between the object and the most object side lens of the optical camera lens group (such as the first lens) on the optical axis is less than 100.0 mm.

[0170] The first lens may have a positive refractive power; thereby, the refractive power of the first lens may be adjusted to converge the light, which helps to simultaneously control the shooting angle of view and increase the amount of light entering. The object side surface of the first lens may be a convex surface near the optical axis; thereby, the surface shape of the first lens may be adjusted, which helps to compress the outer diameter of the object side end of the optical camera lens assembly.

[0171] The second lens may have positive refractive power, thereby helping to compress the volume of the optical camera lens set and correct aberrations. The object side surface of the second lens may be convex near the optical axis, thereby adjusting the surface shape and refractive power of the second lens, helping to improve the quality of the central image.

[0172] The third lens may have negative refractive power, thereby effectively balancing the refractive power of the second lens to avoid excessive aberrations caused by excessive light deflection angles of the second lens. The image side surface of the third lens may be concave near the optical axis, thereby adjusting the refractive power of the third lens to help balance the spherical aberration of the system.

[0173] The fourth lens may have positive refractive power, thereby helping to converge light, effectively control the direction of the light path, and achieve a balance between viewing angle and volume distribution. The image side surface of the fourth lens may be convex near the optical axis, thereby adjusting the direction of light emitted from the fourth lens, and helping to increase the imaging surface.

[0174] The object side surface of the fifth lens may be concave near the optical axis; thereby, the incident angle of light incident on the object side surface of the fifth lens can be controlled to avoid light divergence and poor peripheral relative illumination due to too large an incident angle.

[0175] The object-side surface of the sixth lens element may be a concave surface near the optical axis; thereby, the refractive power of the sixth lens element and the back focal length may be balanced.

[0176] The seventh lens element may have negative refractive power, thereby balancing the refractive power of the image side end of the optical camera lens assembly to increase the focusing quality of each field of view light on the imaging surface and reduce aberrations. The image side surface of the seventh lens element may be concave near the optical axis, thereby assisting in balancing the back focal length of the optical camera lens assembly and correcting off-axis aberrations.

[0177] The three lens groups may include at least five plastic lenses. This can improve the plasticity of the lens to reduce the process cost, and reduce the weight of the lens group to help improve the accuracy of mobile focusing. The three lens groups may include at least six plastic lenses. The three lens groups may include at least seven plastic lenses.

[0178] According to the optical camera lens set disclosed in the present invention, the first lens of the second lens group from the object side to the image side can be a positive lens. This helps to compress the volume of the second lens group. The first lens of the second lens group from the object side to the image side can be the second lens of the optical camera lens set.

[0179] The image side surface of the third lens in the second lens group from the object side to the image side can be a convex surface near the optical axis. In this way, the direction of the light path can be effectively controlled, which helps to increase the imaging surface. Among them, the third lens in the second lens group from the object side to the image side can be the fourth lens of the optical camera lens group.

[0180] In the optical camera lens group disclosed in the present disclosure, at least one reflective element with a function of turning the optical path can be selectively set between the object and the imaging surface on the imaging optical path, thereby facilitating the compression of the volume of the optical camera lens group. The optical path can be reflected at least once through the reflective element. In this way, different optical path directions can be provided to the system, making the lens space configuration more flexible, helping to reduce the limitations on the mechanism and the miniaturization of the optical camera lens group. Among them, the reflective element can be a prism or a mirror, etc., and the present disclosure is not limited to this. Among them, the reflective element can be located between the first lens group and the second lens group. In this way, the reflective element can cooperate with the lens group located on its object side, which helps to simultaneously control the shooting angle of view and increase the amount of light entering to improve the imaging quality.

[0181] Please refer to Fig.42 , is a schematic diagram showing a configuration relationship of a reflective element in an optical camera lens assembly according to the present disclosure. Fig.42As shown, the optical path of the optical camera lens set can be from the object (not shown) to the imaging surface IMG, through the lens group LG1 along the first optical axis OA1 direction to enter the reflective element LF, and after being turned at the reflective surface RF1 of the reflective element, through the lens group LG2 and the filter element along the second optical axis OA2 direction, wherein the reflective element LF is a reflector, which is arranged between the lens group LG1 and the lens group LG2. Compared with a prism, the use of a reflector as a reflective element helps to increase the penetration of light to increase the amount of light entering, and also helps to reduce the generation of stray light to improve the imaging quality. In addition, it helps to reduce the weight and eccentricity sensitivity of the optical camera lens set, improve the assembly qualification rate, and maintain the stability of the image during recording, but the present disclosure is not limited to this. In some embodiments, the reflective element can also be arranged between the lens group and the imaging surface of the optical camera lens set.

[0182] In the case where the reflective element is a prism, the object side surface or the image side surface of the reflective element may be convex near the optical axis. This can provide additional refractive power to the optical camera lens assembly to save space and improve imaging quality, while giving the overall appearance a three-dimensional visual sense. Fig.43 , is a schematic diagram showing another configuration relationship of the reflective element in the optical camera lens assembly according to the present disclosure. Fig.43 As shown, the light path of the optical camera lens group can be from the object (not shown) to the imaging surface IMG, enter the reflective element LF through the light-transmitting surface LP1 along the first optical axis OA1, be turned at the reflective surface RF1 of the reflective element, and then pass through the light-transmitting surface LP2, the lens group LG2 and the filter element along the second optical axis OA2, wherein the light-transmitting surface LP1 can be a convex surface convex toward the object at the near optical axis, and the light-transmitting surface LP2 can be a convex surface convex toward the lens group LG2 at the near optical axis.

Further, the aspherical surface can be made by methods such as plastic injection molding or molding of glass lenses.

[0219] In the optical camera lens assembly disclosed in the present disclosure, if the lens surface is an aspherical surface, it means that the entire or a part of the optically effective area of ​​the lens surface is an aspherical surface.

[0220] In the optical camera lens assembly disclosed in the present disclosure, additives can be selectively added to any (or more) lens materials to produce light absorption or light interference effects to change the lens's transmittance for light in a specific wavelength band, thereby reducing stray light and color deviation. For example, the additive can have the function of filtering out light in the 600-nanometer to 800-nanometer wavelength band in the system to help reduce excess red light or infrared light; or it can filter out light in the 350-nanometer to 450-nanometer wavelength band to reduce excess blue light or ultraviolet light. Therefore, the additive can prevent light in a specific wavelength band from interfering with imaging. In addition, the additive can be evenly mixed in a plastic material and made into a lens using injection molding technology. In addition, the additive can also be configured as a coating on the surface of the lens to provide the above-mentioned effects.

The optical properties of the imaging correction element, such as curvature, thickness, refractive index, position, surface type (convex or concave, spherical or aspherical, diffractive surface and Fresnel surface, etc.), can be adjusted according to the requirements of the imaging device. Generally speaking, the preferred imaging correction element configuration is to arrange a thin plano-concave element with a concave surface toward the object side close to the imaging surface.

[0225] In the optical camera lens assembly disclosed in the present disclosure, at least one aperture stop may be provided, which may be located before the first lens, between each lens, or after the last lens. The aperture stop may be a glare stop or a field stop, etc., which may be used to reduce stray light and help improve image quality.

[0226] In the optical camera lens set disclosed in the present disclosure, the aperture can be configured as a front aperture or a center aperture. The front aperture means that the aperture is set between the object and the first lens, and the center aperture means that the aperture is set between the first lens and the imaging surface. If the aperture is a front aperture, the exit pupil can be at a longer distance from the imaging surface, so that it has a telecentric effect and can increase the efficiency of the CCD or CMOS of the electronic photosensitive element in receiving the image; if it is a center aperture, it helps to expand the field of view of the optical camera lens set.

The mechanical component may include movable parts such as a blade set and a shielding plate; the light control element may include a filter element, an electrochromic material, a liquid crystal layer and other shielding materials. The variable aperture element can enhance the image adjustment capability by controlling the amount of light entering the image or the exposure time. In addition, the variable aperture element may also be the aperture of the present disclosure, which can adjust the image quality, such as the depth of field or the exposure speed, by changing the aperture value.

The optical element may be a filter, a polarizer, etc., but the present disclosure is not limited thereto. In addition, the optical element may be a single-piece element, a composite component, or presented in the form of a film, etc., but the present disclosure is not limited thereto. The optical element may be placed at the object end, the image end, or between the lenses of the optical camera lens set to control the passage of a specific form of light, thereby meeting the application requirements.

[0229] The optical camera lens set disclosed in the present disclosure may include at least one optical lens, optical element or carrier, at least one surface of which has a low-reflection layer, and the low-reflection layer can effectively reduce the stray light generated by the reflection of light at the interface.

[0230] The optical camera lens assembly disclosed in the present disclosure may include a shading element. The opening of the shading element may be non-circular, and the opening may have effective diameters of different sizes in different directions perpendicular to the optical axis. In this way, it can be matched with a non-circular lens or aperture, thereby effectively saving space, and can fully utilize the light passing through the non-circular lens or aperture, which helps to reduce stray light. Among them, the inner hole periphery of the shading element may have a wavy or sawtooth structure.

[0231] In the optical camera lens assembly disclosed in the present disclosure, the object side and the image side are determined according to the direction of the optical axis, and the data on the optical axis are calculated along the optical axis. If the optical axis is turned through an optical path turning element, the data on the optical axis is also calculated along the optical axis.
