technical field

The present application relates to the technical field of cameras, and in particular, to a camera module and an electronic device.

Background technique

The shooting function is the core function of modern smart electronic devices (such as mobile phones). In recent years, consumers have higher and higher requirements for shooting quality, resulting in an increasing number and variety of cameras mounted on electronic devices, as well as increasing cost and space. How to reduce the number of cameras while improving the photo effect is a topic that various manufacturers have been studying, and many manufacturers have also provided their own solutions. In the related art, the front camera and the rear camera are combined into a periscope camera, so that the front and rear cameras share a photosensitive element, and the combined periscope camera is equipped with a rotatable reflective prism. The rotation function reflects the light coming in from the front or the back, enabling front-facing or rear-facing shooting. However, the reflective prism needs to be driven by a motor, which results in a larger volume of the periscope camera and takes up a larger space in an electronic device.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

Reference herein to "an example" or "an implementation" means that a particular feature, structure, or characteristic described in connection with an example or implementation can be included in at least one example of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily separate or alternative embodiments that are mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

Generally speaking, electronic devices such as mobile phones are usually equipped with at least two cameras: a front-facing camera and a rear-facing camera. The front camera and the rear camera are two independent modules, which occupy separate cost and space, causing waste. In order to solve this problem, the manufacturer provides a new type of periscope camera. The periscope camera is provided with two light through holes facing away from each other, and a rotatable reflection prism is arranged corresponding to the through holes. The reflective prism can be rotated to face different light-passing holes, so that the light from different light-passing holes is reflected to the same photosensitive element, so that the front and rear cameras share one photosensitive element. However, since the reflective prism needs to be rotated, a motor must be provided to drive the reflective prism to rotate through the motor, and the motor is usually large in size, and it is integrated in the camera module, which increases the volume of the camera module. At the same time, because the process of rotating the reflective prism to face different light apertures takes a certain amount of time, there is a certain delay in the switching of the front and rear cameras (herein referred to as the lens switching delay), which may bring inconvenience to the user. In addition, the reflective surface of the reflective prism needs to be kept at a preset stop position relative to the light-passing hole to efficiently reflect the light to the photosensitive element, so as to obtain better image quality, and in some cases, the reflective surface cannot reach the preset stop. Location. For example, after the process of power failure and restart, the motor cannot judge the initial stop position of the reflective surface. If the initial stop position deviates from the preset stop position, after driving the reflective prism to rotate the preset angle, the actual stop position of the reflective surface will be obtained. still deviates from the preset stop position. For another example, there is an error in the rotational output of the motor. After the reflective prism is driven to rotate several times, the rotational error accumulates, resulting in a large deviation between the actual stop position of the reflective surface and the preset stop position. It can be understood that when the actual stop position of the reflective surface does not coincide with the preset stop position, the imaging quality will be reduced, that is, the camera module of the above form cannot always maintain a good imaging quality.

Based on this, the present application hopes to provide a solution that can solve but not limited to the above-mentioned technical problems, the details of which will be described in subsequent embodiments.

Please refer to FIG. 1 and FIG. 2 , the present application provides a camera module 10 . The camera module 10 includes: a carrier 110 , a reflector 120 , a photosensitive element 130 , and a light adjustment element 140 .

The first sub-transparent portion T1 is used to transmit the first light, and the second sub-transparent portion T2 is used to transmit the second light. The reflector 120 is accommodated in the carrier 110 and is disposed corresponding to the light-transmitting portion T. As shown in FIG. The photosensitive element 130 is used for receiving the first light and the second light reflected by the reflection member 120 . The dimming element 140 can change the transparency, and includes a first dimming element 141 and a second dimming element 142 . The first dimming element 141 is used to adjust the transmittance of the first light in the process of propagating to the photosensitive element 130 . The second dimming element 142 is used to adjust the transmittance of the second light during the propagation to the photosensitive element 130 .

The carrier 110 may be made of a single material such as plastic or metal, or may be jointly made of multiple materials. The outer contour shape of the carrier 110 may be a rectangular parallelepiped, a cylindrical shape, or the like. The shape of each sub-transmissive portion may be, but not limited to, a circle, an ellipse, a triangle, a rectangle, a regular polygon with a number of sides greater than or equal to 4, and the like. It should be noted that the sub-transparent portion may be a through hole on the carrier 110 , that is, the through hole serves as the sub-transparent portion. The sub light-transmitting portion can also be a solid part on the carrier 110 that can transmit light. For example, the carrier 110 is provided with a through hole, and a light-transmitting mirror that can transmit light is arranged in the through-hole, and the light-transmitting mirror acts as a sub-transparent light department.

It should also be noted that the number of sub-transparent parts included in the translucent part T may be, but not limited to, 2, 3, 4, and the like. The included angles formed by the central axes of adjacent sub-transmissive parts may be, but not limited to, 180°, 135°, 120°, 90°, 80°, 60°, 45°, 30°, and the like. The included angles formed by the central axes of the adjacent sub-transmissive portions may be equal, that is, all the sub-transmissive portions are evenly spaced in the circumferential direction of the carrier 110 . In the structure shown in FIG. 2 , the light-transmitting portion T includes a first sub-light-transmitting portion T1 and a second sub-light-transmitting portion T2 disposed opposite to each other, and the two are separated by 180°. Of course, the structure shown in FIG. 2 is only an exemplary illustration. In an actual product, design factors such as the number, shape, and size of the sub-transmissive parts should be determined according to specific requirements, which are not limited in this application.

The reflector 120 is used to change the propagation directions of the first light and the second light through reflection, so that the first light and the second light can reach the photosensitive element 130 . In the process of reflecting the light, the reflector 120 may reflect the first light and the second light at the same time, or may only reflect one of the first light and the second light. The reflecting member 120 has a first reflecting surface FM1, and the first reflecting surface FM1 is disposed corresponding to the first sub-transmissive portion T1, and is used for reflecting the first light passing through the first sub-transparent portion T1. The reflecting member 120 further has a second reflecting surface FM2, the second reflecting surface FM2 is disposed corresponding to the second sub-transmitting portion T2, and is used for reflecting the second light passing through the second sub-transmitting portion T2.

The dimming element 140 refers to an element that can adjust the transparency through electronic control, temperature control, voltage control, and the like. The dimming element 140 may be, but is not limited to, an electrochromic element. Electrochromic element refers to the glass whose optical properties undergo stable and reversible changes under the action of an external electric field, and its appearance shows reversible changes in color and transparency. By disposing the dimming element 140 on the light propagation path, the transmittance of the light can be adjusted by controlling the transparency of the dimming element 140 . In the present application, the dimming element 140 includes at least a first dimming element 141 and a second dimming element 142, wherein the first dimming element 141 is arranged on the propagation path of the first light, and the second dimming element 142 is arranged on the propagation path of the first light. on the propagation path of the second light. When the first dimming element 141 appears transparent, the first light can be transmitted to the photosensitive element 130; when the first dimming element 141 appears opaque, the first light is blocked by the first dimming element 141, thereby It cannot propagate to the photosensitive element 130 . Similarly, when the second dimming element 142 is transparent, the second light can be transmitted to the photosensitive element 130 ; when the second dimming element 142 is opaque, the second light is blocked by the second dimming element 142 broken, so that it cannot propagate to the photosensitive element 130 . The first dimming element 141 or the second dimming element 142 is an electrochromic element, and the electrochromic element can change its own light transmittance under the action of an external electric field.

The photosensitive element 130 may also be referred to as a photosensitive chip or an image sensor or Sensor, which is used to receive light from the object to be photographed and convert the light signal into an electrical signal. The photosensitive element 130 may be a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS).

Please refer to FIG. 2 , the camera module 10 further includes a lens group 150 , and the lens group 150 is disposed opposite to the photosensitive element 130 . The lens group 150 is used for collecting the light of the photographed scene and focusing the light on the photosensitive element 130 . The lens group 150 may include a plurality of lenses, and the number of lenses may be, but not limited to, 2, 3, 4, 5, 6, and the like. It should be noted that the camera module 10 may be a fixed-focus camera, that is, the lens group 150 and the photosensitive element 130 cannot move relative to each other. The camera module 10 can also be a zoom camera, that is, the lens group 150 and the photosensitive element 130 can move relatively.

To sum up, the camera module 10 provided by the present application is provided with a dimming element 140 , and the dimming element 140 includes a first dimming element 141 and a second dimming element 142 . Since the dimming element 140 can change the transparency, the light transmittance of the first dimming element 141 and the second dimming element 142 can be controlled, so that the transmission of the first light and the second light can be selectively blocked or allowed. . When the first dimming element 141 appears transparent, the first light can be transmitted to the photosensitive element 130; when the first dimming element 141 appears opaque, the first light is blocked by the first dimming element 141, thereby It cannot propagate to the photosensitive element 130 . Similarly, when the second dimming element 142 is transparent, the second light can be transmitted to the photosensitive element 130 ; when the second dimming element 142 is opaque, the second light is blocked by the second dimming element 142 broken, so that it cannot propagate to the photosensitive element 130 . Compared with the related art, in the present application, the dimming element 140 can be used to selectively block or allow the propagation of the first light and the second light, so as to avoid setting an additional motor to drive the reflector 120, so it can be The volume of the camera module 10 is reduced. At the same time, the adjustment of the transparency of the dimming element 140 can be completed in an instant, and the speed is faster than that of switching the light by rotating the reflector 120, thereby avoiding the problem of lens switching delay in the related art. In addition, the reflector 120 in the present application does not need to be rotated, so that it can be fixedly arranged in the carrier 110, so the problem that the light cannot be reflected efficiently due to the rotation of the reflector 120 can be avoided. The camera module 10 can always maintain good image quality.

Referring to FIGS. 2 to 4 , the reflecting member 120 has a first reflecting surface FM1 and a second reflecting surface FM2. The first reflection surface FM1 is disposed corresponding to the first sub-transmissive portion T1. The second reflection surface FM2 is disposed corresponding to the second sub-transmissive portion T2.

Referring to FIG. 2 , in an embodiment, the first reflection surface FM1 is used to reflect the first light to the photosensitive element 130 by mirror reflection. The second reflection surface FM2 is used for reflecting the second light to the photosensitive element 130 in the form of mirror reflection.

In this application, the so-called specular reflection refers to a form in which light does not enter the reflecting member 120 but is reflected by the reflecting surface. Referring to FIG. 2 , optionally, the reflector 120 may further include a backside BM, and the backside BM, the first reflecting surface FM1 , and the third reflecting surface are bent and connected in sequence. Therefore, the reflector 120 is a triangular prism as a whole. Optionally, the reflector 120 is an isosceles prism. Of course, in addition to the structure shown in FIG. 2 , the reflector 120 may also be two plane mirrors. For example, referring to FIG. 3 , the reflector 120 includes a first plane mirror P121 and a second plane mirror P122, the first plane mirror P121 has a first reflection surface FM1, and the second plane mirror P122 has a second reflection surface FM2. It can be understood that, the reflector 120 of the triangular prism type has high structural strength and is also easy to install. The flat mirror type reflector 120 occupies a smaller space, and can make the arrangement of the entire camera module 10 more compact. It should be noted that the specular reflection structures shown in FIG. 2 and FIG. 3 are only illustrative, and of course there are other possible implementations. For example, the reflector 120 may also be composed of a flat mirror and a triangular A reflecting surface FM1, the triangular prism has a second reflecting surface FM2, and other feasible implementations are not described in detail here.

Referring to FIG. 4 , in another embodiment, the first reflective surface FM1 is used to reflect the first light to the photosensitive element 130 through total reflection. The second reflection surface FM2 is used for reflecting the second light to the photosensitive element 130 in the form of total reflection.

In this application, the so-called total reflection refers to the form in which light is reflected by the reflecting surface after entering the reflecting member 120 . Total reflection also has another meaning, that is, total reflection means that when light enters from a medium with a higher refractive index to a medium with a lower refractive index, if the incident angle is greater than a certain critical angle θc (the light is far from the normal), The refracted rays will disappear and all incident rays will be reflected without entering the low refractive index medium. Only in terms of reflection form, total reflection can theoretically reflect 100% of the light, while specular reflection may cause light loss due to refraction. Therefore, the light loss of total reflection is smaller than that of specular reflection.

Optionally, the reflection member 120 includes a first sub-reflection member S121 and a second sub-reflection member S122. The first sub-reflection member S121 has a first reflection surface FM1, a first incident surface RM1, and a first exit surface CM1. The second sub-reflection member S122 has a second reflection surface FM2, a second incident surface RM2, and a second exit surface CM2. During the propagation process, the first light first passes through the first incident surface RM1 , is then totally reflected by the first reflecting surface FM1 , and finally passes through the first exit surface CM1 to be emitted to the photosensitive element 130 . Similarly, during the propagation process, the second light first passes through the second incident surface RM2 , is then totally reflected by the second reflecting surface FM2 , and finally passes through the second exit surface CM2 and is directed towards the photosensitive element 130 . Optionally, the first sub-reflection member S121 and the second sub-reflection member S122 are right-angle triangular prisms.

In the above embodiment, the reflection forms of the first reflection surface FM1 and the second reflection surface FM2 to the light are both specular reflection or total reflection. It should be noted that, in other embodiments, the reflection forms of the first reflection surface FM1 and the second reflection surface FM2 may also be different. That is, the first reflection surface FM1 is specular reflection, and the second reflection surface FM2 is total reflection. Alternatively, the first reflection surface FM1 is total reflection, and the second reflection surface FM2 is specular reflection.

Referring to FIG. 4 , optionally, the angle formed by the side of the first reflection surface FM1 and the second reflection surface FM2 away from the photosensitive element 130 is a preset angle α, and the preset angle α is a right angle or an acute angle. The camera module 10 further includes a lens group 150 , and the lens group 150 is located between the reflector 120 and the photosensitive element 130 . The lens group 150 is used to change the propagation paths of the first light and the second light, so that the area of the photosensitive element 130 receiving the first light and the area receiving the second light do not overlap.

Specifically, setting the preset angle α as a right angle or an acute angle will make the reflection angles of the first light and the second light smaller. Therefore, when the first light and the second light reach the side of the lens group 150 close to the reflector 120 , the regions they pass through do not overlap. After the first light rays and the second light rays pass through the lens group 150 to constrain their propagation paths, they will both fall within the area where the photosensitive element 130 is located, and their falling areas on the photosensitive element 130 do not overlap. Therefore, if the preset angle α is set as a right angle or an acute angle, the photosensitive element 130 can receive the first light and the second light at the same time, so as to achieve simultaneous shooting of different scenes.

Referring to FIG. 5 , optionally, the angle formed by the side of the first reflection surface FM1 and the second reflection surface FM2 away from the photosensitive element 130 is a preset angle α, and the preset angle α is an obtuse angle. The camera module 10 further includes a lens group 150 , and the lens group 150 is located between the reflector 120 and the photosensitive element 130 . The lens group 150 is used to change the propagation paths of the first light and the second light, so that the area of the photosensitive element 130 receiving the first light and the area receiving the second light at least partially overlap.

Specifically, setting the preset angle α as an obtuse angle will make the reflection angles of the first light and the second light larger. Therefore, when the first light and the second light reach the side of the lens group 150 close to the reflector 120, the two The area traversed by the user overlaps. After the first light rays and the second light rays pass through the lens group 150 to constrain their propagation paths, they will both fall into the area of the photosensitive element 130 , and their falling areas on the photosensitive element 130 at least partially overlap. Therefore, if the preset angle α is set as an obtuse angle, whether it is the first light or the second light, the photosensitive element 130 can be irradiated in a large area, so that the photosensitive element 130 can be fully utilized, so that the first light beam formed by the first light can be ensured. An image and a second image formed by the second light have higher imaging quality. Further optionally, the regions of the photosensitive element 130 that receive the first light and the second light are completely overlapped.

Various setting forms of the dimming element 140 will be described below with reference to the accompanying drawings. In terms of the relative positional relationship between the dimming element 140 and the reflector 120 , the arrangement forms of the dimming element 140 can be roughly divided into two categories.

Referring to FIG. 2 , in one embodiment, the first dimming element 141 is disposed on the side of the reflector 120 close to the first sub-transparent portion T1 , so that the first light needs to pass through the reflector 120 before reaching the reflector 120 . The first dimming element 141 is used to control the first light transmittance. Similarly, the second dimming element 142 is disposed on the side of the reflector 120 close to the second sub-transmitting part T2, so that the second light needs to pass through the second dimming element 142 before reaching the reflector 120, so as to realize the The second control of light transmittance.

Referring to FIG. 6 , in another embodiment, the first dimming element 141 is disposed on the side of the reflector 120 close to the photosensitive element 130 , so that the first light emitted from the reflector 120 reaches the photosensitive element 130 before reaching the photosensitive element 130 . It needs to pass through the first dimming element 141, so as to realize the control of the first light transmittance. Similarly, the second dimming element 142 is disposed on the side of the reflecting member 120 close to the photosensitive element 130 , so that the second light emitted from the reflecting member 120 needs to pass through the second dimming element 142 before reaching the photosensitive element 130 , thereby The control of the second light transmittance is realized.

In the case where the first dimming element 141 and the second dimming element 142 are both disposed on the side of the reflector 120 close to the photosensitive element 130, in one embodiment, the first dimming element 141 and the second dimming element 142 142 can be arranged at intervals, that is, the two are independent elements; in another embodiment, the first dimming element 141 and the second dimming element 142 can also be connected as a whole, that is, the two are an integral element.

It should be noted that when the first dimming element 141 is disposed on the side of the reflector 120 close to the first sub-transmissive portion T1 , the second dimming element 142 may be disposed on the side of the reflector 120 close to the photosensitive element 130 . Similarly, when the first dimming element 141 is disposed on the side of the reflector 120 close to the photosensitive element 130 , the second dimming element 142 can be disposed on the side of the reflector 120 close to the second sub-transmissive portion T2 .

Further, in terms of the relative positional relationship between the dimming element 140 and the carrier 110 , the arrangement forms of the dimming element 140 can be roughly divided into three categories.

Referring to FIGS. 2 to 6 , in one embodiment, the dimming element 140 is disposed in the carrier 110 , which is beneficial to protect the dimming element 140 by the carrier 110 from being damaged by foreign objects.

Referring to FIG. 7 , in another embodiment, the dimming element 140 is disposed outside the carrier 110 , so as to make room for the reflector 120 to increase the volume of the reflector 120 , thereby increasing the amount of light that can be reflected.

Referring to FIG. 8 , in another embodiment, the dimming element 140 is disposed in the carrier 110 . For example, the light-transmitting portion T is a through hole passing through the carrier 110 , and the dimming element 140 is disposed in the through hole. Inside.

Referring to FIG. 9 , the present application provides an electronic device 1 . The electronic device 1 includes a device body 20 and the camera module 10 described in any of the above embodiments. The camera module 10 is installed on the device body 20 . The length direction of the camera module 10 may be set along the length direction of the electronic device 1 or may be set along the width direction of the electronic device 1 . Of course, there are other setting forms, which will not be described here. For the introduction of the camera module 10 below, please refer to the descriptions in the foregoing embodiments and the corresponding drawings.

The electronic device 1 may be a mobile phone, a tablet computer, a notebook computer, a camera device, an ultra-mobile personal computer (UMPC), a wearable device (such as a smart watch, a wristband, a VR device, etc.), a television set , vehicle equipment, electronic readers and other equipment. It should be noted that the embodiments of the present application only use the electronic device 1 as a mobile phone for exemplary description, but should not be regarded as a limitation of the present application.

The device body 20 refers to the main body part of the electronic device 1 , and the main body part includes electronic components that realize the main functions of the electronic device 1 and a carrier 110 that protects and carries these electronic components.

Referring to FIG. 9 and FIG. 10 , the device body 20 includes a display screen 210 , a middle frame 220 , and a back cover 230 . The display screen 210 and the back cover 230 are arranged opposite to each other, and are respectively arranged on opposite sides of the middle frame 220 . The camera module 10 is at least partially located between the display screen 210 and the back cover 230 . The display screen 210 has a first light-transmitting port K1 , and the back cover 230 has a second light-transmitting port K2 , and the first light-transmitting port K1 and the second light-transmitting port K2 are disposed opposite to each other. The first sub-transmissive portion T1 of the camera module 10 corresponds to the first translucent port K1, and the second sub translucent portion T2 of the camera module 10 corresponds to the second translucent port K2. Therefore, the electronic device 1 can realize both forward and backward photography.

The first light transmission port K1 may be a through hole on the display screen 210 , or may be a solid area on the display screen 210 through which light can pass. Likewise, the second light transmission port K2 may be a through hole on the back cover 230 , or may be a solid area on the back cover 230 through which light can pass.
