Detailed Description

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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

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

Generally, electronic devices such as cell phones are usually equipped with at least two cameras: the front camera and the rear camera. The front camera and the rear camera are two independent modules, and cost and space are occupied independently, so that waste is caused. In order to solve the problem, manufacturers provide a novel periscopic camera which is provided with two light through holes facing back to back, and a rotatable reflecting prism is arranged corresponding to the through holes. The reflection prism can face different light through holes through rotation, so that light rays from different light through holes are reflected to the same photosensitive element, and the front camera and the rear camera share one photosensitive element. However, since the reflection prism needs to rotate, a motor must be provided to drive the reflection prism to rotate, and the motor is usually bulky and is integrated into the camera module, which results in an increase in the volume of the camera module. Meanwhile, since the process of facing different light-passing holes by rotating the reflection prism consumes a certain amount of time, there is a certain delay in switching between the front and rear cameras (referred to herein as lens switching delay for short), which may cause inconvenience to the user. In addition, the reflecting surface of the reflecting prism can efficiently reflect light to the photosensitive element only by keeping the reflecting surface at the preset stop position relative to the light through hole, so that better imaging quality is obtained, and the reflecting surface cannot reach the preset stop position in some cases. For example, after the power-off and restart process, the motor cannot determine the initial stop position of the reflecting surface, and if the initial stop position deviates from the preset stop position, and then the reflecting prism is driven to rotate by a preset angle, the actual stop position of the reflecting surface still deviates from the preset stop position. For another example, there is an error in the rotational output of the motor, and after driving the reflection prism to rotate for several times, the rotational error is accumulated, thereby causing a large deviation between the actual stop position of the reflection surface and the preset stop position. It is understood that when the actual stop position of the reflecting surface is not coincident with the preset stop position, the imaging quality is reduced, that is, the camera module in the above form cannot always maintain good imaging quality.

Based on this, the present application intends to provide a solution to the above technical problem, but not limited thereto, and the details thereof will be described in the following embodiments.

Referring to fig. 1 and 2, a camera module 10 is provided. The camera module 10 includes: carrier 110, reflector 120, photosensitive element 130, light modulating element 140. The following detailed description is made with reference to the accompanying drawings. It should be noted that in the drawings provided in the present application, a dotted arrow represents a light ray, and the direction indicated by the arrow is the propagation direction of the light ray.

The carrier 110 has a light-transmitting portion T that transmits light, the light-transmitting portion T includes a first sub light-transmitting portion T1 and a second sub light-transmitting portion T2, and the first sub light-transmitting portion T1 and the second sub light-transmitting portion T2 are disposed on the carrier 110 at intervals around the reflector 120. The first sub light-transmitting portion T1 is for transmitting the first light, and the second sub light-transmitting portion T2 is for transmitting the second light. The reflector 120 is accommodated in the carrier 110 and is disposed corresponding to the light-transmitting portion T. The light sensing element 130 is used for receiving the first light and the second light reflected by the reflecting member 120. The dimming element 140 can change transparency, and includes a first dimming element 141 and a second dimming element 142. The first light adjusting element 141 is used for adjusting the transmittance of the first light in the process of propagating to the light sensing element 130. The second light adjusting element 142 is used for adjusting the transmittance of the second light in the process of propagating to the light sensing element 130.

The carrier 110 may be made of a single material such as plastic and metal, or may be made of multiple materials. The outer contour of the carrier 110 may be rectangular parallelepiped, cylindrical, etc. The shape of each sub light-transmitting portion may be, but is not limited to, a circle, an ellipse, a triangle, a rectangle, a regular polygon having a number of sides of 4 or more, or the like. The sub-light-transmitting portion may be a through hole in the carrier 110, that is, the through hole serves as the sub-light-transmitting portion. The sub-light-transmitting portion may also be a solid portion of the carrier 110, for example, a through hole is formed on the carrier 110, a light-transmitting mirror capable of transmitting light is disposed in the through hole, and the light-transmitting mirror serves as the sub-light-transmitting portion.

The number of sub light transmission portions included in the light transmission portion T may be, but is not limited to, 2, 3, 4, or the like. The included angle formed by the central axes of the adjacent sub light-transmitting parts can be, but is not limited to, 180 degrees, 135 degrees, 120 degrees, 90 degrees, 80 degrees, 60 degrees, 45 degrees, 30 degrees and the like. The included angles formed by the central axes of the adjacent sub light transmission parts can be equal, that is, all the sub light transmission parts are uniformly arranged in the circumferential direction of the carrier 110 at intervals. 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 which are oppositely disposed with an interval of 180 °. Of course, the structure shown in fig. 2 is only an exemplary illustration, and in an actual product, design factors such as the number, shape, size, etc. of the sub light transmission portions should be determined according to specific requirements, and the present application is not limited herein.

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

The dimming element 140 is an element that can adjust transparency by electric control, temperature control, voltage control, and the like. The dimming element 140 may be, but is not limited to, an electrochromic element. The electrochromic element is glass which has stable and reversible optical properties under the action of an applied electric field and shows reversible changes in color and transparency in appearance. The light adjusting element 140 is disposed on the light propagation path, so that the transmittance of the light can be adjusted by controlling the transparency of the light adjusting 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 disposed on a propagation path of the first light, and the second dimming element 142 is disposed on a propagation path of the second light. When the first light adjusting element 141 is transparent, the first light can be transmitted to the light sensing element 130; when the first dimming element 141 is opaque, the first light is blocked by the first dimming element 141, and thus cannot be transmitted to the light sensing element 130. Similarly, when the second light adjusting element 142 is transparent, the second light can be transmitted to the light sensing element 130; when the second dimming element 142 is opaque, the second light is blocked by the second dimming element 142 and cannot be transmitted to the light sensing element 130. The first dimming element 141 or the second dimming element 142 is an electrochromic element, and the electrochromic element can change its transmittance under the action of an external electric field.

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

Referring to fig. 2, the camera module 10 further includes a lens set 150, and the lens set 150 is disposed opposite to the photosensitive element 130. The lens group 150 is used for collecting light of a shot object and focusing the light on the photosensitive element 130. The lens assembly 150 may include a plurality of lenses, and the number of the lenses may be, but is not limited to, 2, 3, 4, 5, 6, etc. It should be noted that the camera module 10 can be a fixed-focus camera, that is, the lens group 150 and the photosensitive element 130 are not movable relatively. The camera module 10 can also be a zoom camera, i.e. the lens group 150 and the photosensitive element 130 can move relatively.

In summary, the camera module 10 provided in the present application is provided with the dimming element 140, and the dimming element 140 includes a first dimming element 141 and a second dimming element 142. Since the light modulation element 140 can change transparency, the light transmittances of the first light modulation element 141 and the second light modulation 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 light adjusting element 141 is transparent, the first light can be transmitted to the light sensing element 130; when the first dimming element 141 is opaque, the first light is blocked by the first dimming element 141, and thus cannot be transmitted to the light sensing element 130. Similarly, when the second light adjusting element 142 is transparent, the second light can be transmitted to the light sensing element 130; when the second dimming element 142 is opaque, the second light is blocked by the second dimming element 142 and cannot be transmitted to the light sensing element 130. Compared with the related art, the first light and the second light can be selectively blocked or allowed to propagate through the dimming element 140, so that an additional motor for driving the reflector 120 is avoided, and the volume of the camera module 10 can be reduced. Meanwhile, the adjustment of the transparency of the light adjusting element 140 can be accomplished instantly, which is faster than the speed of switching the light by rotating the reflection member 120, thereby avoiding the problem of the lens switching delay in the related art. In addition, reflector 120 in this application need not rotate to can fix the setting in supporting body 110, consequently can avoid causing the problem that light can not high-efficiently reflect because of reflector 120 is rotatory, in other words, the camera module 10 that this application provided can remain better image quality all the time.

Referring to fig. 2 to 4, the reflector 120 has a first reflection surface FM1 and a second reflection surface FM 2. The first reflection surface FM1 is disposed corresponding to the first sub-transmissive portion T1. The second reflection surface FM2 is provided corresponding to the second sub transmissive portion T2.

Referring to fig. 2, in one embodiment, the first reflective surface FM1 is used for reflecting the first light to the light sensing element 130 through a specular reflection manner. The second reflecting surface FM2 is used to reflect the second light to the photosensitive element 130 by specular reflection.

In the present application, the term specular reflection refers to a form in which light rays are reflected by a reflecting surface without entering the reflecting member 120. Referring to fig. 2, optionally, the reflection member 120 may further include a back surface BM, and the back surface BM, the first reflection surface FM1, and the third reflection surface are sequentially connected in a bending manner, so that the reflection member 120 is a prism as a whole. Optionally, the reflecting member 120 is an isosceles prism. Of course, the reflecting member 120 may be a two-piece plane mirror, instead of the structure shown in fig. 2. 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 FM 2. It is understood that the triangular prism type reflector 120 has a strong structure and is also easy to install. The plane mirror type reflecting member 120, which occupies a smaller space, can make the arrangement of the entire camera module 10 more compact. It should be noted that the form of the specular reflection structure shown in fig. 2 and 3 is only an exemplary illustration, and other possible embodiments also exist, for example, the reflection element 120 may be formed by a flat mirror and a triangular prism, the flat mirror has the first reflection surface FM1, and the triangular prism has the second reflection surface FM2, which are not described in detail herein.

Referring to fig. 4, in another embodiment, the first reflection surface FM1 is used for reflecting the first light to the light sensing element 130 by total reflection. The second reflecting surface FM2 is used to reflect the second light to the light sensing element 130 by total reflection.

In the present application, the total reflection means a form in which light enters the reflecting member 120 and is reflected by the reflecting surface. Total reflection also has another meaning, that is, total reflection means that when a light ray enters a medium with a lower refractive index from a medium with a higher refractive index, if the incident angle is larger than a certain critical angle θ c (the light ray is far from the normal), the refracted light ray will disappear, and all the incident light ray will be reflected without entering the medium with a lower refractive index. In the form of reflection only, total reflection theoretically reflects 100% of light, whereas specular reflection may cause light loss due to refraction, and thus, 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 reflector S121 has a first reflection surface FM1, a first incident surface RM1, and a first exit surface CM 1. The second sub reflector S122 has a second reflection surface FM2, a second incident surface RM2, and a second exit surface CM 2. During the propagation process, the first light beam firstly passes through the first incident surface RM1, then is 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, in the process of propagating, the second light beam firstly passes through the second incident surface RM2, then is totally reflected by the second reflecting surface FM2, and finally passes through the second exit surface CM2 to be emitted to the photosensitive element 130. Alternatively, the first and second sub-reflectors S121 and S122 are right triangular prisms.

In the above embodiments, the first reflection surface FM1 and the second reflection surface FM2 both reflect light in a specular reflection mode or a total reflection mode. In other embodiments, the first reflection surface FM1 and the second reflection surface FM2 may have different reflection forms. That is, the first reflection surface FM1 is specular reflection, and the second reflection surface FM2 is total reflection. Alternatively, the first reflective surface FM1 is total reflective, and the second reflective surface FM2 is specular reflective.

Referring to fig. 4, optionally, an angle formed by the first reflection surface FM1 and the second reflection surface FM2 on the side 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 assembly 150, and the lens assembly 150 is located between the reflector 120 and the photosensitive element 130. The lens group 150 is configured to change propagation paths of the first light and the second light, so that a region of the photosensitive element 130 receiving the first light and a region of the photosensitive element receiving the second light do not overlap.

Specifically, setting the predetermined angle α to be a right angle or an acute angle makes the reflection angle of the first light and the second light smaller, so that when the first light and the second light reach the side of the lens assembly 150 close to the reflective member 120, the areas where the first light and the second light pass through do not overlap. After the first light and the second light pass through the lens assembly 150 to constrain the propagation path, both of the first light and the second light fall into the region of the photosensitive element 130, and the falling regions of the first light and the second light on the photosensitive element 130 do not overlap. Therefore, when the preset angle α is set to be a right angle or an acute angle, the light-sensing element 130 can receive the first light and the second light at the same time, thereby realizing simultaneous photographing of different scenes.

Referring to fig. 5, optionally, an angle formed by the first reflection surface FM1 and the second reflection surface FM2 on the side 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 assembly 150, and the lens assembly 150 is located between the reflector 120 and the photosensitive element 130. The lens group 150 is used for changing 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 predetermined angle α to be an obtuse angle makes the reflection angle of the first light and the second light larger, so that when the first light and the second light reach the side of the lens assembly 150 close to the reflector 120, the areas where the first light and the second light pass overlap. After the first light and the second light pass through the lens assembly 150 to constrain the propagation path, both of the first light and the second light fall into the region of the photosensitive element 130, and the falling regions of the first light and the second light on the photosensitive element 130 at least partially overlap. Therefore, setting the preset angle α to be an obtuse angle, the photosensitive element 130 can be irradiated with a large area regardless of the first light or the second light, so that the photosensitive element 130 is fully utilized, and thus, a high image quality of the first image formed by the first light and the second image formed by the second light can be ensured. Further alternatively, the regions of the photosensitive element 130 receiving the first light and the second light may completely overlap.

Various configurations of the light adjusting element 140 will be described below with reference to the drawings. The arrangement form of the dimming element 140 can be roughly classified into two types in terms of the relative positional relationship between the dimming element 140 and the reflector 120.

Referring to fig. 2, in an embodiment, the first light adjusting element 141 is disposed on a side of the reflection member 120 close to the first sub-transparent portion T1, so that the first light ray needs to pass through the first light adjusting element 141 before reaching the reflection member 120, thereby controlling the transmittance of the first light ray. Similarly, the second light adjusting element 142 is disposed on a side of the reflection member 120 close to the second sub light-transmitting portion T2, so that the second light ray needs to pass through the second light adjusting element 142 before reaching the reflection member 120, thereby realizing control of the transmittance of the second light ray.

Referring to fig. 6, in another embodiment, the first light adjusting element 141 is disposed on a side of the reflection element 120 close to the light sensing element 130, so that the first light emitted from the reflection element 120 passes through the first light adjusting element 141 before reaching the light sensing element 130, thereby controlling the transmittance of the first light. Similarly, the second light adjusting element 142 is disposed on a side of the reflection element 120 close to the light sensing element 130, so that the second light emitted from the reflection element 120 needs to pass through the second light adjusting element 142 before reaching the light sensing element 130, thereby realizing control of the transmittance of the second light.

In a case that the first dimming element 141 and the second dimming element 142 are both disposed on a side of the reflection member 120 close to the light sensing element 130, in one embodiment, the first dimming element 141 and the second dimming element 142 may be disposed at intervals, that is, they are independent elements; in another embodiment, the first dimming element 141 and the second dimming element 142 may also be connected as a whole, i.e. they are a single element.

It should be noted that, when the first light adjusting element 141 is disposed on the side of the reflection member 120 close to the first sub light-transmitting portion T1, the second light adjusting element 142 may be disposed on the side of the reflection member 120 close to the light sensing element 130. Also, when the first dimming element 141 is disposed at a side of the reflection member 120 close to the light sensing element 130, the second dimming element 142 may be disposed at a side of the reflection member 120 close to the second sub light-transmitting portion T2.

Further, the arrangement of the dimming element 140 can be roughly classified into three types in terms of the relative position relationship between the dimming element 140 and the carrier 110.

Referring to fig. 2 to 6, in one embodiment, the dimming element 140 is disposed inside the carrier 110, so that the carrier 110 can protect the dimming element 140 from being damaged by a foreign object.

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, and 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 light modulating element 140 is disposed in the carrier 110, for example, the transparent portion T is a through hole penetrating through the carrier 110, and the light modulating element 140 is disposed in the through hole.

Referring to fig. 9, the present application provides an electronic device 1, where the electronic device 1 includes a device body 20 and the camera module 10 described in any of the above embodiments, and the camera module 10 is mounted on the device body 20. The length direction of the camera module 10 can be set along the length direction of the electronic device 1, and also can be set along the width direction of the electronic device 1, and of course, other setting forms also exist, which are not described herein any more. For the following description of the camera module 10, please refer to the description of the previous embodiments and the accompanying 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 bracelet, and a VR device), a television, a vehicle-mounted device, and an electronic reader. It should be noted that, in the embodiment of the present application, the electronic device 1 is merely used as a mobile phone for exemplary illustration, but the present application is not limited thereto.

The device body 20 is a main body portion of the electronic device 1, and the main body portion includes electronic components that implement the main functions of the electronic device 1, and a carrier 110 that protects and carries the electronic components.

Referring to fig. 9 and 10, the device body 20 includes a display screen 210, a middle frame 220, and a rear cover 230. The display screen 210 and the rear cover 230 are disposed opposite to each other and disposed on opposite sides of the middle frame 220. The camera module 10 is at least partially located between the display screen 210 and the rear cover 230. The display screen 210 has a first light transmission opening K1, the rear cover 230 has a second light transmission opening K2, and the first light transmission opening K1 and the second light transmission opening K2 are oppositely disposed. The first sub light-transmitting portion T1 of the camera module 10 corresponds to the first light-transmitting opening K1, and the second sub light-transmitting portion T2 of the camera module 10 corresponds to the second light-transmitting opening K2. Therefore, the electronic apparatus 1 can realize both the forward shooting and the backward shooting.

The first light-transmitting opening 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. Similarly, the second light-transmitting opening K2 can be a through hole on the rear cover 230, or can be a solid area of the rear cover 230 through which light can pass.

The first light enters the camera module 10 through the first light-transmitting opening K1 and the first sub light-transmitting portion T1, and is then reflected to the photosensitive element 130 via the reflecting member 120, thereby completing front-end shooting. The second light can enter the camera module 10 through the second light-transmitting opening K2 and the second sub light-transmitting portion T2, and then is reflected to the photosensitive element 130 via the reflecting member 120, thereby completing the rear-view shooting. The front shooting is a shooting mode in which the camera module 10 obtains a scene image on the side of the electronic device 1 having the display screen 210. The post-shooting mode is a shooting mode in which the camera module 10 obtains an image of a subject on the side of the electronic device 1 away from the display screen 210.

The application of the camera module 10 provided in the above embodiment in the electronic device 1 will be described from the control perspective.

Referring to fig. 11, the electronic device 1 further includes a processor 30, and the processor 30 is electrically connected to the camera module 10. The processor 30 is configured to receive a shooting instruction and adjust the transparency of the dimming element 140 according to the shooting instruction.

That is, the user can issue a photographing instruction including photographing requirement information of the user through the device body 20. After receiving the shooting command, the processor 30 controls the transparency of the dimming element 140 through the electrical signal, so as to meet the shooting requirement of the user. The photographing instruction may be, but is not limited to, triggered by the user touching the electronic device 1, pressing a physical key (such as a side key) of the electronic device 1, inputting a voice command to the electronic device 1, and the like. The shooting instruction may be, but is not limited to, a front shooting instruction, a rear shooting instruction, an on-screen shooting instruction, and the like.

Referring to fig. 12, optionally, the display screen 210 is a touch screen with a touch function, and the display screen 210 is directly or indirectly electrically connected to the processor 30. The user may select a shooting option by touching the display screen 210, and the display screen 210 generates a shooting instruction corresponding to the shooting option selected by the user after sensing the touch operation of the user, and directly or indirectly sends the shooting instruction to the processor 30. After receiving the shooting instruction from the display screen 210, the processor 30 generates a corresponding light control signal according to the shooting instruction, where the light control signal is used to control the transparency of the light adjusting element 140.

The transparency of the dimming element 140 includes a first transparency and a second transparency, which are two transparency levels of the dimming element 140. When the dimming element 140 is in the first transparency, it represents a transparent ray; when the light adjusting element 140 is in the second transparency, it indicates that the light can be blocked.

Optionally, the shooting instruction includes a first shooting instruction, and the first shooting instruction is a pre-shooting instruction. The processor 30 controls the first light adjusting element 141 to adjust to the first transparency for transmitting light and controls the second light adjusting element 142 to adjust to the second transparency for shielding light according to the first photographing instruction. That is, after the first photographing instruction is issued, the second light adjusting element 142 will block the transmission process of the second light to the light sensing element 130, and the first light adjusting element 141 can transmit the first light, so that the light sensing element 130 will finally receive the first light.

Optionally, the shooting instruction includes a second shooting instruction, and the second shooting instruction is a post shooting instruction. The processor 30 controls the first light adjusting element 141 to adjust to the second transparency for shading light and controls the second light adjusting element 142 to adjust to the first transparency for transmitting light according to the second shooting instruction. That is, after the second shooting command is sent, the first dimming element 141 blocks the transmission process of the first light to the light sensing element 130, and the second dimming element 142 can transmit the second light, so that the light sensing element 130 finally receives the second light.

The electronic device 1 is taken as a mobile phone for exemplary explanation: the shooting interface of the mobile phone display screen 210 may be configured with a front shooting option and a rear shooting option, where the front shooting option corresponds to the first shooting instruction and the rear shooting option corresponds to the second shooting instruction. The user may select a desired photographing option by touching the display screen 210 to trigger a corresponding photographing instruction. Specifically, when the user selects the front shooting option, the first shooting instruction is triggered, and the processor 30 controls the first dimming element 141 to adjust to light transmission and controls the second dimming element 142 to adjust to light blocking according to the first shooting instruction, so as to switch to the front shooting mode. When the user selects the rear-view shooting option, the second shooting command is triggered, and the processor 30 controls the second dimming element 142 to adjust to light transmission and controls the first dimming element 141 to adjust to light shading according to the second shooting command, so as to switch to the rear-view shooting mode.

Optionally, the angle formed by the first reflection surface FM1 and the second reflection surface FM2 on the side away from the photosensitive element 130 is a preset angle α, and the preset angle α is an obtuse angle, so that the areas of the photosensitive element 130 receiving the first light and the second light at least partially overlap. For the first reflection surface FM1 and the second reflection surface FM2, please refer to the description of the previous embodiments. The shooting instruction includes a third shooting instruction, and the processor 30 controls the first dimming element 141 and the second dimming element 142 to alternately block light at a preset frequency according to the third shooting instruction.

It should be noted that "the first dimming element 141 and the second dimming element 142 alternately block light at a predetermined frequency" means that the first dimming member alternately blocks light and transmits light at the predetermined frequency, and the second dimming member transmits light when the first dimming member blocks light and blocks light when the first dimming member transmits light.

In the present embodiment, the processor 30 controls the first and second light-modulating members to alternatively block light at a predetermined frequency, and the light-blocking is in reverse, that is, the light-transmitting is alternatively blocked, so that the light-sensing element 130 will alternatively receive the first light and the second light. With this arrangement, the display screen 210 can simultaneously display a first image formed by the first light and a second image formed by the second light (referred to as a same-screen display). It is understood that when the preset frequency is greater than or equal to the frequency threshold, the photosensitive element 130 can obtain a preset number of first images and second images in a unit time, and the preset number is large enough to enable the user to see the continuous, non-stuck, dynamic first images and second images.

When the third shooting instruction is triggered, the processor 30 controls the first dimming element 141 and the second dimming element 142 to alternately block light at a preset frequency according to the third shooting instruction.

Optionally, the angle formed by the first reflection surface FM1 and the second reflection surface FM2 on the side away from the photosensitive element 130 is a preset angle α, and the preset angle α is an obtuse angle, so that the areas of the photosensitive element 130 receiving the first light and the second light at least partially overlap. The shooting instruction comprises a fourth shooting instruction, the fourth shooting instruction comprises a first sub-shooting instruction, and the first dimming element 141 and the second dimming element 142 are controlled to be adjusted to be transparent according to the first sub-shooting instruction.

In the present embodiment, the processor 30 controls the first dimming element 141 and the second dimming element 142 to adjust to a light-transmitting state, so that the light sensing element 130 can receive the first light and the second light simultaneously, and the first image formed by the first light and the second image formed by the second light at least partially overlap, thereby obtaining a superposition effect of different images.

Optionally, the angle formed by the first reflection surface FM1 and the second reflection surface FM2 on the side away from the photosensitive element 130 is a preset angle α, and the preset angle α is a right angle or an acute angle, so that the areas of the photosensitive element 130 receiving the first light and the second light do not overlap. The shooting instruction includes a fourth shooting instruction, the fourth shooting instruction includes a second sub-shooting instruction, and the processor 30 controls the first dimming element 141 and the second dimming element 142 to adjust to the first transparency so as to transmit light according to the second sub-shooting instruction.

In the embodiment, the first light modulating element 141 and the second light modulating element 142 are both adjusted to be in a light transmitting state, so that the light sensing element 130 can receive the first light and the second light at the same time, and the first image formed by the first light and the second image formed by the second light are not overlapped.
