Description

Technical Field

[0001] The present application belongs to the technical field of camera modules, and specifically relates to a camera module and an electronic device. Background Art

[0002] In order to meet the dual-focal-length imaging needs of consumers, in the related art, a camera module is set in the electronic device, and the camera module includes two independent cameras. The two independent cameras increase the internal space occupancy rate of the electronic device, resulting in an increase in the size and weight of the electronic device. At the same time, in order to facilitate the assembly of the two cameras, it is necessary to open multiple holes on the housing of the electronic device and add multiple step structures, which increases the processing difficulty of the electronic device, increases the production cost of the electronic device, and reduces the appearance of the electronic device. Summary of the invention

[0003] The present application aims to provide a camera module and an electronic device, which solves the problem that the electronic device in the related art meets the use requirements of dual-focal-length imaging by setting up two independent cameras, which leads to an increase in the size and weight of the electronic device, as well as an increase in the production cost of the electronic device and a reduction in the appearance aesthetics of the electronic device.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application proposes a camera module, comprising: a housing; a first lens, disposed in the housing, and the first lens at least partially exposed from the housing; a first image sensor, disposed in the housing; a second image sensor, disposed in the housing, the first image sensor and the second image sensor being arranged at intervals along a first direction; a second lens, disposed in the housing; a prism, at least a portion of the prism being located in the housing, the prism being movably connected to the housing, and the prism being able to move relative to the housing to switch between a first position and a second position; when the prism is in the first position, the second lens is located between the prism and the first image sensor, light is incident on the prism through the first lens, reflected by the prism to the second lens, and projected to the first image sensor through the second lens; when the prism is in the second position, the prism and the second image sensor are arranged opposite to each other, light is incident on the prism through the first lens, and reflected by the prism to the second image sensor.

[0006] In a second aspect, an embodiment of the present application proposes an electronic device, including: a camera module as in the first aspect.

[0007] In an embodiment of the present application, a camera module includes a housing, a first lens, a first image sensor, a second image sensor, a second lens and a prism.

[0008] The housing serves as a mounting carrier for the first lens, the first image sensor, the second image sensor, the second lens and the prism, and has the function of mounting and fixing the first lens, the first image sensor, the second image sensor, the second lens and the prism.

[0009] The first lens is at least partially exposed from the housing, that is, the housing will not block the first lens, and light can enter the first lens.

[0010] The positions of the first lens, the first image sensor, the second image sensor and the second lens relative to the housing are fixed. The prism is movably connected to the housing, and the prism can move relative to the housing to switch between the first position and the second position.

[0011] When the prism moves to the first position, the second lens is located between the prism and the first image sensor, and the first lens, prism, first image sensor and second lens constitute a first camera. Light is incident on the prism through the first lens, reflected by the prism to the second lens, and projected to the first image sensor through the second lens. That is, the light is focused by the first lens and transmitted to the prism, reflected by the prism to the second lens, processed by the second lens and transmitted to the first image sensor, the first image sensor converts the optical signal into an electrical signal, the electrical signal is processed by the internal circuit of the first image sensor and then outputs the image data, thereby completing the telephoto shooting.

[0012] When the prism moves to the second position, the prism and the second image sensor are arranged opposite to each other. The first lens, the prism and the second image sensor constitute the second camera. Light is incident on the prism through the first lens and is reflected by the prism to the second image sensor. That is, the light is focused by the first lens and then transmitted to the prism, and is reflected by the prism to the second image sensor. The second image sensor converts the light signal into an electrical signal, and the electrical signal is processed by the internal circuit of the second image sensor and then outputs the image data, thereby completing the telephoto shooting.

[0013] It can be seen that the camera module of the present application can meet the use requirements of dual focal length images. The first camera and the second camera share the first lens and the prism, which can also be said that the first lens and the prism are both shared structures. Compared with the two independent cameras set in the electronic device in the related art, the camera module of the present application reduces the number of first lenses, reduces the number of prisms, and thus reduces the weight of the camera module, can reduce the size of the camera module, can reduce the production cost of the camera module, and thus can reduce the space occupancy rate of the camera module in the electronic device, and provides structural support for the thinning of the electronic device. At the same time, the setting can also simplify the assembly process of the electronic device, reduce the assembly steps of the electronic device, and help to further reduce the production cost of the electronic device. In addition, since the first camera and the second camera share the first lens, the first lens reveals the shell of the camera module. In this way, compared with the related art of opening multiple holes and adding multiple step structures on the shell of the electronic device, the present application can reduce the number of openings and the number of step structures of the shell of the electronic device, can simplify the processing process of the shell of the electronic device, reduce the processing steps of the shell of the electronic device, which is conducive to reducing the production cost of the electronic device and improving the aesthetics of the appearance of the electronic device.

[0031] The following is combined with Figures 1 to 8 The camera module 10 and the electronic device 1 provided in the embodiments of the present application are described.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, according to some embodiments of the present application, a camera module 10 is proposed, including: a housing 100; a first lens 200, which is arranged in the housing 100, and the first lens 200 is at least partially exposed from the housing 100; a first image sensor 300, which is arranged in the housing 100; a second image sensor 400, which is arranged in the housing 100, and the first image sensor 300 and the second image sensor 400 are arranged at intervals along a first direction; a second lens 500, which is arranged in the housing 100; a prism 600, at least a part of which is located in the housing 100, and the prism 600 is movably connected to the housing 100, and the prism 600 can move relative to the housing 100 to switch between a first position and a second position; when the prism 600 is in the first position, the second lens 500 is located between the prism 600 and the first image sensor 300, and light is incident on the prism 600 through the first lens 200, is reflected by the prism 600 to the second lens 500, and is projected to the first image sensor 300 through the second lens 500; when the prism 600 is in the second position, the prism 600 and the second image sensor 400 are arranged opposite to each other, and light is incident on the prism 600 through the first lens 200, and is reflected by the prism 600 to the second image sensor 400.

[0033] In the embodiment of the present application, the camera module 10 includes a housing 100 , a first lens 200 , a first image sensor 300 , a second image sensor 400 , a second lens 500 and a prism 600 .

[0034] The housing 100 serves as a mounting carrier for the first lens 200 , the first image sensor 300 , the second image sensor 400 , the second lens 500 and the prism 600 , and has the function of mounting and fixing the first lens 200 , the first image sensor 300 , the second image sensor 400 , the second lens 500 and the prism 600 .

[0035] The first lens 200 is at least partially exposed from the housing 100 , that is, the housing 100 does not block the first lens 200 , and light can be emitted into the first lens 200 .

[0036] The first lens 200, the first image sensor 300, the second image sensor 400 and the second lens 500 are fixed relative to the housing 100. The prism 600 is movably connected to the housing 100 and can move relative to the housing 100 to switch between the first position and the second position.

[0037] When the prism 600 moves to the first position, the second lens 500 is located between the prism 600 and the first image sensor 300, and the first lens 200, the prism 600, the first image sensor 300 and the second lens 500 constitute the first camera 12. Light is incident on the prism 600 through the first lens 200, reflected by the prism 600 to the second lens 500, and projected to the first image sensor 300 through the second lens 500. That is, the light is focused by the first lens 200 and transmitted to the prism 600, reflected by the prism 600 to the second lens 500, and transmitted to the first image sensor 300 after being processed by the second lens 500. The first image sensor 300 converts the optical signal into an electrical signal, and the electrical signal is processed by the internal circuit of the first image sensor 300 and then outputs the image data, thereby completing the telephoto shooting. Figure 1 As shown, the first camera 12 and the second camera 14 are both represented by dotted boxes.

[0038] When the prism 600 moves to the second position, the prism 600 is arranged opposite to the second image sensor 400. The first lens 200, the prism 600 and the second image sensor 400 constitute the second camera 14. The light is incident on the prism 600 through the first lens 200, and is reflected by the prism 600 to the second image sensor 400. That is, the light is focused by the first lens 200 and then transmitted to the prism 600, and is reflected by the prism 600 to the second image sensor 400. The second image sensor 400 converts the optical signal into an electrical signal, and the electrical signal is processed by the internal circuit of the second image sensor 400 and then outputs the image data, thereby completing the telephoto shooting.

[0039] It can be seen that the camera module 10 of the present application can meet the use requirements of dual-focal length images and can realize the setting of two periscope telephoto cameras. The first camera 12 and the second camera 14 share the first lens 200 and the prism 600. It can also be said that the first lens 200 and the prism 600 are shared structures. Compared with the two independent cameras set in the electronic device in the related art, the camera module 10 of the present application reduces the number of first lenses 200 and the number of prisms 600, thereby reducing the weight of the camera module 10, reducing the size of the camera module 10, reducing the production cost of the camera module 10, and thus reducing the space occupancy rate of the camera module 10 in the electronic device 1, providing structural support for the thinness of the electronic device 1. At the same time, the setting can also simplify the assembly process of the electronic device 1, reduce the assembly steps of the electronic device 1, and help to further reduce the production cost of the electronic device 1. In addition, since the first camera 12 and the second camera 14 share the first lens 200, the first lens 200 reveals the housing 100 of the camera module 10. Thus, compared with the related art of opening multiple holes and adding multiple step structures on the housing of the electronic device, the present application can reduce the number of openings and the number of step structures in the housing of the electronic device 1, can simplify the processing procedure of the housing of the electronic device 1, reduce the processing steps of the housing of the electronic device 1, and is beneficial to reducing the production cost of the electronic device 1 and improving the aesthetic appearance of the electronic device 1.

[0040] In some embodiments, a length of a diagonal line of at least one of the first image sensor 300 and the second image sensor 400 is greater than or equal to 1 / 1.56 inches.

[0041] In this embodiment, the structures of the first image sensor 300 and the second image sensor 400 are defined.

[0042] A length of a diagonal line of at least one of the first image sensor 300 and the second image sensor 400 is greater than or equal to 1 / 1.56 inches.

[0043] That is, the length of the diagonal of the first image sensor 300 is greater than or equal to 1 / 1.56 inch. Alternatively, the length of the diagonal of the second image sensor 400 is greater than or equal to 1 / 1.56 inch. Alternatively, the length of the diagonal of the first image sensor 300 and the second image sensor 400 are both greater than or equal to 1 / 1.56 inch.

[0044] When the length of the diagonal of at least one of the first image sensor 300 and the second image sensor 400 is greater than or equal to 1 / 1.56 inch, at least one of the first image sensor 300 and the second image sensor 400 is a large-bottom high-resolution image sensor, and the camera module 10 can meet the needs of long-focus and high-resolution imaging. This setting enriches the use functions of the camera module 10, can meet the diverse usage needs of users, and is conducive to improving the product's performance and market competitiveness.

[0045] In some other embodiments, a diagonal length of at least one of the image sensors is less than 1 / 1.56 inches.

After being processed by the second lens 500, the light enters the surface of the first image sensor 300, and the first image sensor 300 converts the optical signal into an electrical signal, which is processed by the circuit inside the first image sensor 300 and outputs image data, thereby completing the telephoto shooting of the first camera 12.

Among them, the image quality includes brightness and color reproduction, etc., which are not listed here one by one.

[0057] In some embodiments, Figure 3 As shown, along the second direction, the orthographic projection of the optical axis of the first lens 200 on the horizontal plane 1308 is a first point 1302, the orthographic projection of the center 330 of the imaging area of ​​the first image sensor on the horizontal plane 1308 is a second point 1304, and the orthographic projection of the center of the imaging area of ​​the second image sensor 400 on the horizontal plane 1308 is a third point 1306. The first point 1302, the second point 1304 and the third point 1306 are collinear, and the first point 1302 is located between the second point 1304 and the third point 1306.

[0058] In this embodiment, the matching structure of the first lens 200 , the first image sensor 300 , and the second image sensor 400 is defined.

The first point 1302, the second point 1304, and the third point 1306 are collinear, and the first point 1302 is located between the second point 1304 and the third point 1306.

[0060] This setting limits the propagation path of light, can ensure the quality of the image, and improve the performance of the camera module 10. The quality of the image includes brightness and color reproduction, etc., which are not listed here one by one.

[0061] In some embodiments, Figure 1 As shown, the camera module 10 is cross-sectioned along a direction perpendicular to the third direction; in the cross-section, the outer edge of the first image sensor 300 includes a first side 310 and a second side 320 connected, the length of the first side 310 is greater than the length of the second side 320, the outer edge of the second image sensor 400 includes a third side 410 and a fourth side 420 connected, the length of the third side 410 is greater than the length of the fourth side 420, and the portion of the outer edge of the prism 600 opposite to the second lens 500 is the fifth side 640; the first side 310 is parallel to the fifth side 640, or the first side 310 is perpendicular to the fifth side 640; the third side 410 is parallel to the fifth side 640, or the third side 410 is perpendicular to the fifth side 640.

[0062] In this embodiment, a matching structure of the first image sensor 300 , the second image sensor 400 , and the prism 600 is defined.

[0063] The camera module 10 is cross-sectioned along a direction perpendicular to the third direction; in the cross-section, the outer edge of the first image sensor 300 includes a first edge 310 and a second edge 320 connected, the length of the first edge 310 is greater than the length of the second edge 320, the outer edge of the second image sensor 400 includes a third edge 410 and a fourth edge 420 connected, the length of the third edge 410 is greater than the length of the fourth edge 420, and the portion of the outer edge of the prism 600 opposite to the second lens 500 is the fifth edge 640.

[0064] The matching structure of the first side 310, the second side 320, the third side 410, the fourth side 420 and the fifth side 640 can be limited according to the placement position of the camera module 10 in the electronic device 1, so that the first side 310 is parallel to the fifth side 640, or the first side 310 is perpendicular to the fifth side 640, the third side 410 is parallel to the fifth side 640, or the third side 410 is perpendicular to the fifth side 640, which can ensure the use requirements of the picture size.

[0065] For example, Figure 1 As shown, the first side 310 , the third side 410 , and the fifth side 640 all extend along the first direction, and the second side 320 and the fourth side 420 all extend along the second direction.

[0100] According to some other embodiments of the present application, the electronic device 1 includes: a camera module 10 as in any of the above embodiments.

[0101] The electronic device 1 provided in the present application includes the camera module 10 of any of the above embodiments, and therefore has all the beneficial effects of the above camera module 10, which will not be described one by one here.

[0102] Exemplarily, the electronic device 1 can be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop, a mobile computer, an augmented reality device (also known as an AR (Augmented Reality) device), a virtual reality device (also known as a VR (Virtual Reality) device) and a handheld game console, etc.

[0103] Exemplarily, the present application reasonably arranges the structure of the camera module 10, so that the camera module 10 includes a housing 100, a first lens 200, a first image sensor 300, a second image sensor 400 and a prism 600. The prism 600 can move relative to the housing 100 to switch between a first position and a second position.

[0104] When the prism 600 moves to the first position, the second lens 500 is located between the prism 600 and the first image sensor 300 , and the first lens 200 , the prism 600 , the first image sensor 300 , and the second lens 500 constitute the first camera 12 .

[0105] When the prism 600 moves to the second position, the prism 600 is disposed opposite to the second image sensor 400. The first lens 200, the prism 600 and the second image sensor 400 constitute the second camera 14.

[0106] The first camera 12 and the second camera 14 share the first lens 200 and the prism 600. In other words, the first lens 200 and the prism 600 are both shared structures. The two periscope telephoto camera designs can be realized, which is beneficial to improving the product image, hand-holding and appearance experience.

[0107] The camera module 10 of the present application can simultaneously meet the photography requirements of dual focal lengths and telephoto high resolution, can reduce the size of the camera module 10, can reduce the weight of the camera module 10, and thereby reduce the space occupied by the camera module 10 in the electronic device 1, can reduce the weight of the electronic device 1, can reduce the cost of the camera module 10, and is conducive to reducing the production cost of the electronic device 1.

[0108] Exemplarily, the camera module 10 includes a periscope telephoto camera module.

[0109] Since the first camera 12 and the second camera 14 share the first lens 200 , the number of camera openings and the step structure are reduced in the design of the entire back cover, thereby improving the aesthetics of the product appearance.

[0110] like Figure 1 , Figure 2 and Figure 3As shown, the camera module 10 includes a first lens 200 , a second lens 500 , a prism 600 , a first image sensor 300 and a second image sensor 400 .

[0112] When the prism 600 moves to the second position, the first lens 200, the prism 600 and the second image sensor 400 constitute the second camera 14. Specifically, the second camera 14 includes a second periscope telephoto camera.

[0113] The first image sensor 300 , the second image sensor 400 , the first lens 200 , and the second lens 500 are fixed components, and their positions are relatively fixed.

[0114] The prism 600 is a movable component, and the prism 600 can be horizontally displaced.

[0115] When the prism 600 is located at the first position, the first image sensor 300 and the second lens 500 are located directly above the second reflective bevel 620 of the prism 600, and the first lens 200 is located directly above the first reflective bevel 610. Figure 1 The solid line in illustratively shows the prism 600 .

[0116] When the prism 600 is located at the second position, the second image sensor 400 is located directly above the first reflective bevel 610, and the first lens 200 is located directly above the second reflective bevel 620. Figure 1 The dotted line in illustratively illustrates the prism 600 .

[0117] The second lens 500 is located directly below the first image sensor 300, and the second lens 500 is located directly above the second reflective slope 620. The optical axis 510 of the second lens coincides with the center 330 of the imaging area of ​​the first image sensor in the projection direction.

[0118] Along the second direction, the orthographic projection of the optical axis of the first lens 200 on the horizontal plane 1308 is a first point 1302, the orthographic projection of the center 330 of the imaging area of ​​the first image sensor on the horizontal plane 1308 is a second point 1304, and the orthographic projection of the center of the imaging area of ​​the second image sensor 400 on the horizontal plane 1308 is a third point 1306. The first point 1302, the second point 1304 and the third point 1306 are collinear, and the first point 1302 is located between the second point 1304 and the third point 1306.

[0119] Exemplarily, the long side direction of the first image sensor 300 and the second image sensor 400 may be parallel to the long side direction of the prism 600. Alternatively, the long side direction of the first image sensor 300 and the second image sensor 400 and the long side direction of the prism 600 are perpendicular to each other. Alternatively, the long side direction of one of the first image sensor 300 and the second image sensor 400 is perpendicular to the long side direction of the prism 600, and the long side direction of the other of the first image sensor 300 and the second image sensor 400 is parallel to the long side direction of the prism 600.

[0120] like Figure 6 , Figure 7 and Figure 8 As shown, when the user starts the camera of the electronic device 1, the user first selects the photography focal length through the user interface 22 of the camera of the electronic device 1. After the electronic device platform end 2 receives the focal length instruction, it controls the movement of the prism 600 to the corresponding first position or second position according to the demand, and then starts the first image sensor 300, the second image sensor 400, the focusing device 1100 and the anti-shake device 1200 of the camera module 10 to complete the shooting. Figure 7 0.5X, 1X, 2X and 3X in the figure indicate magnification.

[0121] When the prism 600 moves to the first position, the light is focused by the first lens 200 and then transmitted to the first surface 632 of the prism 600, enters the interior of the prism 600 through the first surface 632, is reflected by the first reflecting bevel 610 and then incident on the reflecting surface 636, is reflected by the second reflecting bevel 620, and reaches the second lens 500 through the second surface 634. The light is processed by the second lens 500 and then enters the surface of the first image sensor 300. The first image sensor 300 converts the optical signal into an electrical signal, which is processed by the circuit inside the first image sensor 300 and then outputs image data, thereby completing telephoto shooting.

[0122] When the prism 600 moves to the second position, the light is focused by the first lens 200 and then transmitted to the second surface 634 of the prism 600, enters the interior of the prism 600 through the second surface 634, is reflected by the second reflecting bevel 620 and then incident on the reflecting surface 636, is reflected by the first reflecting bevel 610, and then reaches the surface of the second image sensor 400 through the first surface 632. The second image sensor 400 converts the optical signal into an electrical signal, which is processed by the circuit inside the second image sensor 400 and then outputs image data, thereby completing telephoto shooting.

[0123] The first surface 632 and the second surface 634 of the prism 600 are both fully transparent surfaces, and thus can be used as both incident surfaces and exit surfaces.

[0133] The camera module 10 further includes a supporting device 1000 , and the supporting device 1000 includes at least one of a ball supporting device, a guide rod supporting device, and a suspension wire supporting device.

[0134] The camera module 10 further includes a focusing device 1100. The focusing device 1100 can be arranged on the first lens 200, and use a dynamic lens for focusing. The focusing device 1100 can also be designed on the first image sensor 300 and the second image sensor 400, respectively, and use a dynamic image sensor for focusing. The focusing device 1100 can also be arranged on the second lens 500 and the second image sensor 400, respectively, that is, one uses a dynamic lens for focusing, and the other uses a dynamic image sensor for focusing.

[0135] The camera module 10 further includes an anti-shake device 1200. The anti-shake device 1200 can be arranged on the first lens 200, and adopts optical anti-shake of a dynamic lens. The anti-shake device 1200 can also be arranged on the first image sensor 300 and the second image sensor 400, respectively, and adopts anti-shake of a dynamic image sensor. The anti-shake device 1200 can also be arranged on the second lens 500 and the second image sensor 400, respectively, that is, one adopts anti-shake of a dynamic lens, and the other adopts anti-shake of a dynamic image sensor.

[0136] The camera module 10 of the present application can simultaneously meet the photography requirements of dual focal lengths and telephoto high resolution.

[0137] The present application can reduce the size and weight of the camera module 10, thereby reducing the space occupied by the camera module 10 in the electronic device 1, which is beneficial to reducing the weight of the electronic device 1 and improving the user's hand-held experience.

[0138] The present application reasonably arranges the structure of the camera module 10 , which can reduce the cost of the camera module 10 and the overall cost of the electronic device 1 .

[0139] Since the first camera 12 and the second camera 14 share the first lens 200 , the number of openings and step structures can be reduced in the design of the entire rear cover, thereby improving the aesthetics of the product appearance.
