[0036] Some embodiments of the present disclosure will be described in detail with reference to the drawings, of which examples are shown. The following description, in relation to the drawings, refers to the same or similar elements using like reference numerals. Various changes, modifications and equivalents thereof will become apparent to those skilled in the art after an understanding of the present disclosure. For example, the order of the operations described herein is merely an example, and is not limited to those set forth herein, but can be changed as apparent after an understanding of the present disclosure, except for operations that must be performed in a specific order. In addition, the description of features known in the art can be omitted for the sake of clarity and brevity.
[0037] The implementations described in some embodiments of the present disclosure below do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0038] To meet the demand for camera shooting, more and more electronic devices use long-focus camera modules. However, the size of the long-focus camera module is large, which needs to occupy a large internal space of the electronic device. In the related art, a periscopic long-focus module is often used, that is, a prism is arranged on one side of the lens or lens group, and the size of the long-focus camera module is reduced by changing the optical path through the prism. However, this way only reduces the size of the long-focus camera module in a single direction, and does not reduce the overall size of the long-focus camera module.
[0039] Therefore, the present disclosure provides a camera module and an electronic device, wherein the camera module optimizes the required space of the camera module in the prism object side and image side directions by arranging the prism between the first lens group with positive refractive power and the second lens group with negative refractive power. Moreover, by arranging the prism between the first lens group and the second lens group, the optical path length between the first lens group and the second lens group is increased to reduce the required space when the second lens group moves along the optical axis of the camera module for focusing, and further reduce the required space of the camera module.
[0040] Figure 1 is a structural schematic diagram of a camera module according to some embodiments of the present disclosure, as Figure 1As shown, the camera module includes a first lens group 1, a prism 3, a second lens group 2, and a photosensitive element 6. The first lens group 1 has positive focal power, and includes at least two positive lenses arranged on the same optical axis. The prism 3 is located on the image side of the first lens group 1. The second lens group 2 has negative focal power, and includes at least two negative lenses arranged on the same optical axis. The second lens group 2 is located on the image side of the prism 3, and moves along the optical axis of the camera module. The photosensitive element 6 is located on the image side of the second lens group 2.
[0041] As shown in the figure, Figure 1 A rectangular coordinate system is defined, in which the y-axis direction is perpendicular to the photosensitive surface of the photosensitive element 6, and the x-axis direction is parallel to the photosensitive surface of the photosensitive element 6. By arranging the prism 3 to change the light path, the required space of the camera module in the y-axis direction is reduced. The first lens group 1 includes at least two positive lenses arranged on the same optical axis, so that the first lens group 1 has a relatively high positive focal power to meet the imaging effect at the macro end. The second lens group 2 moves along the optical axis to change the focal point position to realize focusing of the lens on the photosensitive element 6 at different object distances. The second lens group 2 includes at least two negative lenses arranged on the same optical axis, so that the second lens group 2 has a relatively low negative focal power to meet the imaging effect at the tele end. The prism 3 is arranged between the first lens group 1 with positive focal power and the second lens group 2 with negative focal power, and the space occupied by the prism 3 is used as the light path space between the first lens group 1 and the second lens group 2, so as to reduce the required space for the second lens group 2 to move along the optical axis of the camera module for focusing, and further reduce the required space of the camera module in the y-axis direction.
[0042] Figure 2 is a schematic diagram of a camera module at a macro end according to some embodiments of the present disclosure. Figure 3 is a schematic diagram of a camera module at a tele end according to some embodiments of the present disclosure. As shown in the figure, Figure 2 and Figure 3 As shown in the figures, by arranging the prism 3 between the first lens group 1 and the second lens group 2, the preset distance d between the first lens group 1 and the second lens group 2 is effectively increased in the limited internal space of the camera module.
[0043] In embodiments of the present disclosure, the first lens group 1 includes a first lens 11, a second lens 12, and a third lens 13 arranged on the same optical axis. The first lens 11 and the second lens 12 both have positive focal power, which is conducive to the incidence and collection of light in the object-side field of view, and can make the first lens group 1 have a relatively high positive focal power. The third lens 13 has negative focal power, which is used to correct the aberration generated by the first lens 11 and the second lens 12.
[0044] In embodiments of the present disclosure, the third lens 13 satisfies the relationship:
[0045] -0.4≤(R5-R6) / (R5+R6)≤0
[0046] wherein R5 is the curvature radius of the surface of the third lens 13 facing the object side at the optical axis, and R6 is the curvature radius of the surface of the third lens 13 facing the image side at the optical axis. By reasonably configuring the curvature radii of the two sides of the third lens 13, the curvature radius of the object side surface of the third lens 13 is not excessively increased compared with the image side surface, so as to suppress the generated aberration. Moreover, the curvature radius of the object side surface of the third lens 13 is not excessively close to the image side surface, so that the third lens 13 has a certain negative refractive power, which is beneficial to the miniaturization of the camera module.
[0047] In the embodiment of the present disclosure, the second lens group 2 comprises a fourth lens 21, a fifth lens 22 and a sixth lens 23 arranged on the same optical axis. The fourth lens 21 and the fifth lens 22 both have negative focal power, the fifth lens 22 is located on the image side of the fourth lens 21, and the fifth lens 22 is located on the image side of the fourth lens 21 for delaying the angle between the light and the optical axis.
[0048] The sixth lens 23 has negative focal power or positive focal power, the sixth lens 23 is located on the image side of the fifth lens 22, and the sixth lens 23 has negative focal power or positive focal power, which is used to correct the spherical aberration, coma and distortion astigmatism and the like generated by the fourth lens 21 and the fifth lens 22.
[0049] In the embodiment of the present disclosure, the fourth lens 21 satisfies the relationship:
[0050] -0.4≤(R5-R6) / (R5+R6)≤0
[0051] wherein R7 is the curvature radius of the surface of the fourth lens 21 facing the object side at the optical axis, and R8 is the curvature radius of the surface of the fourth lens 21 facing the image side at the optical axis. By reasonably configuring the curvature radii of the two sides of the fourth lens 21, the curvature radius of the object side surface of the fourth lens 21 is not excessively increased compared with the image side surface, so as to suppress the generated aberration. Moreover, the curvature radius of the object side surface of the fourth lens 21 is not excessively close to the image side surface, so that the fourth lens 21 has a certain negative refractive power, which is beneficial to the miniaturization of the camera module.
[0052] In the embodiment of the present disclosure, the fifth lens 22 satisfies the relationship:
[0053] -0.1≤(R9-R10) / (R9+R10)≤0
[0054] Wherein, R9 is the radius of curvature of the object-side surface of the fifth lens 22 at the optical axis, and R10 is the radius of curvature of the image-side surface of the fifth lens 22 at the optical axis. By rationally configuring the radii of curvature on both sides of the fifth lens 22, the radius of curvature of the object-side surface of the fifth lens 22 is not excessively increased compared to the image-side surface, thereby suppressing the resulting aberrations. Furthermore, the radius of curvature of the object-side surface of the fifth lens 22 is not excessively close to that of the image-side surface, giving the fifth lens 22 a certain negative refractive power, which is beneficial for the miniaturization of the camera module.
[0055] In the embodiments of this disclosure, the first lens group 1 satisfies the following relationship:
[0056] TTL / IH ≥ 2.5
[0057] Wherein, IH is the distance on the optical axis from the object-facing surface of the TTL first lens group 1 to the photosensitive element 6, and IH is the diagonal dimension of the photosensitive element 6. This helps to reduce the overall size of the camera module, thereby saving the space occupied by the camera module.
[0058] In embodiments of this disclosure, the aperture F of the camera module is greater than or equal to 2.1. For example... Figure 1 As shown, the camera module also includes an aperture stop 4, which is located on the object side of the first lens 11 and is used to control the aperture of the camera module.
[0059] In the embodiments of this disclosure, the camera module satisfies the following relation:
[0060] 0.114≤IH / (TTL*F)≤0.175
[0061] Where IH is the diagonal dimension of the photosensitive element 6, the distance from the object-side surface of the TTL first lens group 1 to the photosensitive element 6 on the optical axis, and F is the aperture of the camera module. When the above formula is satisfied, the ratio of lens height to imaging surface is within a small range, and the miniaturization of the camera module can be achieved through a reasonable structural layout.
[0062] In some embodiments, the camera module further includes a filter element 5. The filter element 5 is located between the prism 3 and the photosensitive element 6. The filter element 5 may include, but is not limited to, a low-pass filter, an infrared cut-off filter, a microlens, or an RGB color filter.

[0070]
[0071] In this embodiment, among the first lens 11 to the sixth lens 23, all of the 12 aspherical surfaces on the object side and the image side, R1-R12, are Qcon type, and the surface shape is defined by the following formula:
[0072]
[0073] wherein z represents the depth of the aspherical surface (the vertical distance between a point on the aspherical surface at a distance Y from the optical axis and a tangent plane at the vertex of the aspherical surface on the optical axis); r represents the distance of a point on the aspherical surface from the optical axis; k represents the conic constant; rn represents the normalized curvature; u represents r / rn, a m represents the mth order aspherical coefficient; Q m represents the mth order Qcon polynomial. The use of the Qcon polynomial to represent the aspherical surface has the advantage that the surface shape is more stable and is less likely to have a sudden change point, and the light rays are less likely to be abnormal.

[0089] It should be understood that the features of various of the disclosed embodiments described herein can be combined with each other, unless specifically noted otherwise. As used in this document, the term “and / or” includes any one of the listed items, as well as any combination of any two or more of the listed items; it will be understood that the terms “coupled,” “attached,” “connected,” “joined,” “connected,” “fixed” and the like, as used in the embodiments of the disclosure, should be construed in an inclusive sense, e.g., to the term “connected” should be understood to encompass both direct connections and indirect connections, as well as fixed and non-fixed connections, and that the term “connected” can mean the connection between two elements, or the interaction between two elements, unless expressly specified and limited otherwise. The specific meaning of the above terms in this document can be understood by those of ordinary skill in the art according to the specific context.
[0090] In addition, the word “over” as used in the context of a component, element, or material layer formed on or located over a surface can be used to mean that the component, element, or material layer is positioned (e.g., placed, formed, deposited, etc.) “indirectly” on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the word “over” as used in the context of a component, element, or material layer formed on or located over a surface can optionally also have the specific meaning of the component, element, or material layer being positioned (e.g., placed, formed, deposited, etc.) “directly” on the surface, e.g., in direct contact with the surface.
[0091] It will be understood that spatially relative terms, such as “above,” “upper,” “below,” and “lower,” and the like, can be used herein for ease of description to describe one element’s or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. Such spatially relative terms can be intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as above other element(s) or feature(s) would then be oriented below the other element(s) or feature(s). Thus, the term “above” can encompass both an orientation that is above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0092] Although terms such as "first", "second", and "third" can be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited to the terms. Instead, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Therefore, the first element, component, region, layer or section mentioned in the examples described herein can also be referred to as the second element, component, region, layer or section without departing from the teachings of the examples. In addition, the terms "first", "second" are only for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.
[0093] It can be further understood that the terms "first", "second" and the like are used to describe various information, but the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or importance. In fact, the expressions "first", "second" and the like can be used interchangeably. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the disclosure.
[0094] In the description herein, the meaning of "a plurality of" is at least two, referring to two or more, for example, two, three, and the like, unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a", "said" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise. In addition, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more" unless otherwise specified or clearly directed to the singular form from the context.
[0095] It should be understood that the features of various embodiments of the present disclosure described herein can be combined with each other unless otherwise specifically indicated. As used herein, the term "and / or" includes any one of the related listed items and any combination of any two or more; "and / or", describing the association relationship of the associated objects, means that there can be three relationships, for example, A and / or B can represent: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents that the front and rear associated objects are in an "or" relationship. Similarly, "at least one of" includes any one of the related listed items and any combination of any two or more.
[0096] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete manner. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. Also, the singular forms of words such as "a," "an," and "the," are intended to mean the
[0097] Also, although the disclosure has been described with respect to only one or more implementations thereof, those skilled in the art will readily appreciate that other alternatives can be used. It is contemplated that various modifications can be made by one of ordinary skill in the art having the benefit of this disclosure, and this disclosure is intended to cover any and all such modifications provided such modifications come within the scope of the claims. Specifically with respect to the various functions performed by the components (e.g., elements, resources, etc.) described above, the terms used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the described function (functionally equivalent), even if not structurally equivalent. In addition, although a particular feature of the disclosure can have been disclosed with respect to only one of several implementations, such feature can be combined with one or more other features of the other implementations as can be desired and advantageous for any given or particular application. Furthermore, to the extent that "comprising", "having", "including", or like terms are used in the detailed description, claims, or drawings, such terms are intended to be inclusive of that which is described, in their entirety.
[0098] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the features disclosed herein. Aspects of the disclosure can be modified by varying structural and / or functional features disclosed herein in accordance with the principles of the disclosure. Therefore, the present disclosure is intended to cover any and all adaptations and modifications of the various embodiments of the disclosure and falls within the scope of the appended claims. Accordingly, claims are not intended to be limited to the exact elements shown and described to have technical effect for any particular application.
