DETAILED DESCRIPTION

[0048] ​​​​​​To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0049] The electronic device provided in this disclosure is an electronic device with shooting and image processing capabilities. The electronic device can be a mobile phone, tablet computer, handheld computer, laptop computer, vehicle-mounted device, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, etc. This disclosure does not impose any special limitations on the specific form of the electronic device.

[0050] Combination Figure 1 , Figure 2 and Figure 3 As shown, the electronic device provided in this embodiment includes a camera module 3 and a protective glass. The camera module 3 is used to capture images or videos. When the camera module 3 is disposed on the front of the electronic device, it can be used to capture the scene located on one side of the front of the electronic device, and can be called a front-facing camera; when the camera module 3 is disposed on the back of the electronic device, it can be used to capture the scene located on one side of the back of the electronic device, and can be called a rear-facing camera. The camera module 3 may include a lens, an image sensor, and a lens motor. The lens can focus external light onto the photosensitive surface of the image sensor to form an optical image (i.e., a light signal). The image sensor can convert the light signal into an electrical signal. The lens can move along the optical axis under the drive of the lens motor to achieve focusing, thereby forming a clear optical image through the image sensor.

[0051] In the electronic device provided in this embodiment, the camera module 3 is fixed in the electronic device; a protective glass covers the lens of the camera module 3 to protect the lens of the camera module 3. That is, the protective glass can serve as a protective cover for the lens in the camera module 3.

[0052] The protective glass comprises a first glass 1 and a second glass 2, at least one of the first glass 1 and the second glass 2 is movable to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, and the first concave curved surface 121 is opposite to the first convex curved surface 211. By adjusting the distance between the first glass 1 and the second glass 2, the entering angle of the light can be changed. When the distance between the first glass 1 and the second glass 2 is smaller, only the light with a smaller angle with the optical axis can enter the lens of the camera module 3, and at this time, the imaging range of the camera module 3 is also reduced accordingly; when the distance between the first glass 1 and the second glass 2 is larger, the light with a larger angle with the optical axis can enter the lens of the camera module 3, the range of the light entering the lens is larger, and the imaging range of the camera module 3 is also increased accordingly. By changing the distance between the first glass 1 and the second glass 2, the propagation path of the light passing through the first glass 1 and the second glass 2 can be adjusted, so that the range of the entering angle of the light entering the lens can be controlled, and the size of the scene range that can be captured by the camera module 3 can be changed.

[0053] In an embodiment, when the first glass 1 and the second glass 2 are attached (i.e., the first concave curved surface 121 and the first convex curved surface 211 are attached), the curvatures of the first concave curved surface 121 and the first convex curved surface 211 are mutually offset due to the complementary concave-convex structure, so that the ability of the protective glass to change the propagation path of the light is weakened, or even the propagation path of the light is not changed (equivalent to the propagation path of the light without the protective glass). At this time, the propagation path of the light passing through the protective glass is not obviously affected, and it can be considered that the light enters the lens of the camera module 3 at the angle without the protective glass, and at this time, the imaging range of the camera module 3 is also not affected (the same as the imaging range without the protective glass). When the first glass 1 and the second glass 2 are separated, the first concave curved surface 121 of the first glass 1 becomes a concave lens, and the first convex curved surface 211 of the second glass 2 becomes a convex lens. When the light first passes through the first concave curved surface 121 of the first glass 1, the light is deflected away from the central axis of the lens, so as to expand the propagation angle of the light, and then the diffused light passes through the first convex curved surface 211 of the second glass 2 to adjust the angle and enters the lens of the camera module 3. Compared with the state when the first glass 1 and the second glass 2 are attached, the separated structure can make more light with a range of angles enter the lens, which is equivalent to that the effective light receiving range of the camera module 3 is expanded, so that a wider picture information can be captured. The larger the distance between the first glass 1 and the second glass 2 is, the wider the range of the light entering the lens of the camera module 3 is, and the larger the scene range that can be captured by the camera module 3 is.

[0054] Therefore, the protective glass has the optical adjustment capability in addition to the function of protecting the camera module 3. By adjusting the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, the function of the traditional independent ultra-wide-angle camera can be replaced, and there is no need to additionally equip an image sensor and a corresponding circuit of the ultra-wide-angle camera, thereby saving space and reducing the use of the ultra-wide-angle camera, thereby reducing the assembly difficulty and potential failure risk of the device.

[0055] The embodiment of the present disclosure is different from the zoom lens of a single-lens reflex camera and the telescopic lens of a card camera. The embodiment of the present disclosure utilizes the original camera module 3 on the electronic device, covers the protective glass in front of the lens of the original camera module 3, and installs the first glass 1 with the first concave curved surface 121 and the second glass 2 with the first convex curved surface 211 on the electronic device. The first glass 1 and the second glass 2 can be separated or attached. The propagation path of light is adjusted by changing the distance between the first glass 1 and the second glass 2, so that the imaging range of the original camera module 3 of the electronic device can be changed. The embodiment of the present disclosure changes the imaging range of the camera module 3 by optical adjustment of the protective glass based on the original camera module 3, without changing the physical structure of the camera module 3, such as the lens group and the focal length of the lens of the camera module 3 and other key parameters. The scheme of the embodiment of the present disclosure removes the independent ultra-wide-angle camera and saves space, which meets the design logic of thin and integrated electronic devices.

[0056] The zoom lens of a single-lens reflex camera or the telescopic lens of a card camera adjusts the focal length by the relative displacement of multiple lens groups inside the lens, thereby changing the field of view angle. The essence is to realize zooming through the optical structure adjustment of the camera module itself, which belongs to an independent optical zoom system and is irrelevant to the UV mirror or protective mirror (protective glass) in front of the lens. The zoom lens of a single-lens reflex camera needs to accommodate multiple lens groups and driving motors, and the lens itself is thick, which cannot be adapted to electronic devices with ultra-thin bodies. Although the card camera is more compact than the single-lens reflex camera, the telescopic lens still needs to reserve space for extension, which will increase the thickness of the body.

[0057] The embodiment of the present disclosure is different from the scheme of changing the shooting effect by installing a filter in front of the camera module 3 and changing different filters. In the scheme of changing different filters, a rotating clamping groove, such as a filter ring similar to a camera lens, is usually designed on the periphery of the camera module 3. The design of the rotating clamping groove increases the diameter of the lens module and the complexity of the body. The process of rotating and replacing the filter needs to pause shooting, manually install or remove or rotate the parts, and easily miss the shooting opportunity. In the embodiment of the present disclosure, the protective glass can be integrated into the shell 6 of the electronic device. The position of the protective glass is set in front of the lens of the original camera module 3 of the electronic device, and the thickness is controlled within the size range of the original design of the electronic device. No additional body space is reserved for the protective glass. The surface of the protective glass and the shell 6 of the electronic device can form a flat appearance surface, which meets the design goal of thinning and integration of the electronic device.

[0058] In an embodiment of the present application, the protective glass covers the lens of the camera module 3. The protective glass includes a first glass 1 and a second glass 2. At least one of the first glass 1 and the second glass 2 can move to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2. The first concave curved surface 121 is opposite to the first convex curved surface 211. At least one of the first glass 1 and the second glass 2 can move to affect the imaging range of the camera module 3. The closer the distance between the first concave curved surface 121 and the first convex curved surface 211, the smaller the influence on the imaging range of the camera module 3. The farther the distance between the first concave curved surface 121 and the first convex curved surface 211, the greater the influence on the imaging range of the camera module 3.

[0059] The imaging range refers to the physical scene range that can be captured and recorded on the photosensitive surface of the image sensor (such as the CMOS chip) by the camera module 3 or the optical system. The original configuration parameters (such as the lens focal length and the sensor size) of the camera module 3 determine its basic imaging range, that is, the original imaging range of the camera module 3 itself. At least one of the first glass 1 and the second glass 2 can move. The distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2 can be changed to perform optical compensation without changing the original configuration parameters of the camera module 3. The imaging capability boundary of the camera module 3 is expanded. The camera module 3 can have a larger imaging range under the original configuration parameters. The embodiment of the present disclosure adjusts the imaging range by changing the shape of the protective glass outside the lens (adjusting the distance between the two glasses). On the basis of retaining all the performances of the original hardware of the camera module 3, such as the original focusing speed and the weak light imaging capability, the fixed camera module 3 has the ability to dynamically expand the imaging range by adjusting the distance between the first glass 1 or the second glass 2 outside the lens.

[0060] Adjusting the focal length of the camera module 3 to be shorter can expand the shooting range, and adjusting the camera module 3 can capture a wider range of scenes. When a wider range of scenes needs to be captured, the distance between the first concave surface 121 and the first convex surface 211 can be increased, and the optical adjustment effect of the first concave surface 121 and the first convex surface 211 is superimposed with the short focal length of the camera module 3 itself, which can further expand the imaging range of the camera module 3, so as to expand the shooting range, such as being able to accommodate a complete indoor space, a group photo, or a large scene landscape, etc.

[0061] Optionally, when the distance between the first glass 1 and the second glass 2 is 0, the first glass 1 and the second glass 2 are attached as a flat plate, which does not affect the original configuration parameters of the camera module 3, and the camera module 3 works in the default state according to its original imaging range.

[0062] Optionally, when the distance between the first glass 1 and the second glass 2 is increased, the camera module 3 works in the default state according to the original configuration parameters. The composite optical structure formed by the first concave surface 121 and the first convex surface 211 refracts light, which is equivalent to adding a dynamic field of view expander to the fixed parameter lens, so that it covers a larger imaging range without changing the original internal lens and sensor of the camera module 3.

[0063] The distance between the first glass 1 and the second glass 2 can be linearly related to the imaging range. When the distance between the first glass 1 and the second glass 2 is shortened, the imaging range of the camera module 3 is correspondingly reduced, and when the distance between the first glass 1 and the second glass 2 is increased, the imaging range of the camera module 3 is correspondingly increased. The user can control the distance between the first glass 1 or the second glass 2 to achieve stepless and smooth switching from the original imaging range of the camera module 3 to the expanded imaging range.

[0064] The corresponding relationship between the distance of the first glass 1 or the second glass 2 and the imaging range can be preset by an algorithm, for example, the distance between the first glass 1 and the second glass 2 can be increased by 0.1 mm, and the field of view is expanded by 5°. The electronic device system can control the distance between the first glass 1 and the second glass 2 according to user operation or scene recognition.

[0065] In an embodiment of the present application, a protective glass is arranged on the lens of the camera module 3, and the protective glass comprises a first glass 1 and a second glass 2. At least one of the first glass 1 and the second glass 2 is movable to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, and the first concave curved surface 121 is opposite to the first convex curved surface 211. At least one of the first glass 1 and the second glass 2 is movable to change the angle between the first incident light 51 of the first surface 11 of the first glass 1 and the optical axis, so that the imaging range of the camera module 3 changes. The first surface 11 of the first glass 1 is opposite to the first concave curved surface 121, the incident light of the first surface 11 of the first glass 1 comprises the first incident light 51 and the second incident light 52, the second incident light 52 is parallel to the optical axis, and the first surface 11 of the first glass 1 is a plane. The closer the distance between the first concave curved surface 121 and the first convex curved surface 211, the smaller the angle between the first incident light 51 of the first surface 11 of the first glass 1 and the optical axis. The farther the distance between the first concave curved surface 121 and the first convex curved surface 211, the greater the angle between the first incident light 51 of the first surface 11 of the first glass 1 and the optical axis. The smaller the angle between the first incident light 51 and the optical axis, the more the edge light captured by the camera module 3 is converged, the narrower the light range entering the camera module 3, and the smaller the field of view FOV. The greater the angle between the first incident light 51 and the optical axis, the more the edge light captured by the camera module 3 is dispersed, the wider the light range entering the lens of the camera module 3, and the greater the field of view FOV. The embodiment can realize dynamic adjustment of the field of view without changing the internal structure of the camera module 3.

[0066] In the camera module 3, for example, the limit capture range of the CMOS chip is a first threshold value, and the scene beyond the range cannot be captured by the CMOS chip. The FOV of the camera module 3 is a second threshold value, the second threshold value is less than the first threshold value, and after the distance between the first glass 1 and the second glass 2 is increased, the FOV is a third threshold value, the third threshold value is greater than the second threshold value and less than the first threshold value, and it can also be captured by the CMOS chip.

[0067] For example, the limit capture range of the CMOS chip is 150°, the FOV of the camera module 3 is 120°, and after the distance between the first glass 1 and the second glass 2 is increased, the FOV is 140°.

[0068] The embodiment utilizes the capture capability of the original CMOS chip in the camera module 3, realizes controllable expansion of the FOV between the “original range of the camera module 3” and the “CMOS limit” through the distance adjustment of the first glass 1 and the second glass 2, can fully release the potential of the CMOS chip, and realizes the expansion of the capture range without wasting hardware performance.

[0069] In the embodiment, the protective glass is independent of the internal structure of the camera module 3 such as the lens group and the sensor, and only by adjusting the propagation path of the light passing through the first glass 1 and the second glass 2, the incident angle range of the light entering the lens can be realized, the size of the scene range that can be captured by the camera module 3 is changed, and therefore the camera module 3 of the existing electronic device can be directly adapted, without the need to redesign the lens focal length, sensor size, etc., which can reduce the research and development cost and production complexity.

[0070] In an embodiment of the present application, the protective glass covers the lens of the camera module 3, and the protective glass includes the first glass 1 and the second glass 2. At least one of the first glass 1 and the second glass 2 can move to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, and the first concave curved surface 121 is opposite to the first convex curved surface 211. The first concave curved surface 121 and the first convex curved surface 211 are complementary, that is, the first concave curved surface 121 and the first convex curved surface 211 are completely matched in shape, and when the first concave curved surface 121 and the first convex curved surface 211 are in contact, they can be seamlessly attached to form a complete flat protective glass. When the first glass 1 and the second glass 2 are in the first relative position, the first concave curved surface 121 and the first convex curved surface 211 are in contact. The first concave curved surface 121 and the first convex curved surface 211 are attached without gaps, and the curvatures of the first concave curved surface 121 and the first convex curved surface 211 are offset due to the complementary concave-convex structure. The protective glass only has a physical protection function, and the propagation path of the light passing through the protective glass is not significantly affected. It can be considered that the light enters the lens of the camera module 3 at the angle without the protective glass, and at this time the imaging range of the camera module 3 is not affected. When the first glass 1 and the second glass 2 are in the second relative position, the first concave curved surface 121 and the first convex curved surface 211 are separated, and the protective glass can expand the imaging range of the camera module 3. In the separated state of the first concave curved surface 121 and the first convex curved surface 211, the composite optical structure formed by the separation of the first concave curved surface 121 and the first convex curved surface 211 causes the light to be deflected away from the center axis of the lens, thereby expanding the propagation angle of the light. Subsequently, the diffused light enters the lens of the camera module 3 after being adjusted in angle by the first convex curved surface 211 of the second glass 2. Compared with the state when the first glass 1 and the second glass 2 are attached, this separated structure allows more angle range of light to enter the lens, which is equivalent to expanding the effective light receiving range of the camera module 3, thereby realizing the expansion of the field of view, capturing more extensive picture information, and realizing the function of a traditional independent ultra-wide-angle camera without the need for additional image sensors and corresponding circuits of the ultra-wide-angle camera.

[0071] When the first glass 1 is in contact with the second glass 2 (first relative position), the complementary first concave curved surface 121 and the first convex curved surface 211 are completely fitted, the protective glass has weak ability to change the light propagation direction or does not change the light propagation direction, at this time, the camera module 3 maintains the original imaging range; when the first glass 1 is separated from the second glass 2 (second relative position), the first concave curved surface 121 and the first convex curved surface 211 form a concave lens and a convex lens, when the light first passes through the first concave curved surface 121 of the first glass 1, the light will be deflected away from the lens center axis, thereby expanding the light propagation angle, then the diffused light passes through the first convex curved surface 211 of the second glass 2 to adjust the angle and enters the lens of the camera module 3, the effective light receiving range of the camera module 3 is expanded, thereby realizing the expansion of the field of view angle and capturing more extensive picture information. This only needs two control positions 0 or 1, one-step switching, which can maximize the reduction of hardware complexity and improve reliability.

The coverage range of the light shielding layer is at least greater than the area exposed to the device housing 6 after the first glass 1 moves, so that after the first glass 1 moves, the light shielding layer also extends to the newly exposed area after the first glass 1 moves, ensuring that the side gap is always in a light shielding state during the full stroke movement of the first glass 1, further improving the imaging stability of the electronic device.

[0077] In a specific embodiment, the electronic device includes a camera module 3 and a protective glass, the protective glass covers the lens of the camera module 3, the protective glass includes a first glass 1 and a second glass 2, at least one of the first glass 1 and the second glass 2 can move to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2. The electronic device further includes a power member 41 and a driver; optionally, the power member 41 includes a motor and a screw rod. The motor is connected with the screw rod as a power output source, and the power of the motor is transmitted to the driver through the rotation of the screw rod. The driver includes a motion assembly. The driver is a transmission bridge between the power member 41 and the protective glass, and the power of the power member 41 can be transmitted to the first glass 1 and / or the second glass 2 through the motion assembly.

[0078] The motion assembly includes a transmission assembly 42, a first motion assembly 43, and a second motion assembly 44, the transmission assembly 42 receives the output of the power member 41, and the transmission assembly 42 includes a cam set that cooperates with the screw rod of the power member 41.

[0079] The first movement assembly 43 is configured to rotate with the transmission assembly 42. The first movement assembly 43 comprises a first movement track 431, as shown in Figure 7 and Figure 8 The second movement assembly 44 is fixed to the second part 14 of the first glass 1 and is configured to cooperate with the first movement track 431 to separate the first glass 1 from the second glass 2. The first movement track 431 is a pre-designed rigid path. The first movement track 431 of the first movement assembly 43 can be a guide rail, a sliding groove, or a guide hole, etc. The second movement assembly 44 can comprise a sliding block, a protruding column, or a guide column, etc. The sliding block, the protruding column, or the guide column, etc. are embedded in the first movement track 431 and move along the first movement track 431, which can move the first glass 1 in a predetermined direction (e.g. the optical axis direction).

[0080] The first movement track 431 can be a first spiral track. The first spiral track can convert the rotational torque of the first movement assembly 43 into a linear thrust along the optical axis direction, thereby pushing the first glass 1. By rotating the motor in a forward direction or a reverse direction, the first glass 1 can be moved towards or away from the second glass 2, thereby changing the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2.

[0081] In an embodiment, the first movement assembly 43 further comprises a second movement track 432. The third movement assembly 45 is fixed to the second glass 2 and is configured to cooperate with the second movement track 432 to move the first glass 1 away from the lens of the camera module 3 and to move the second glass 2 towards the lens of the camera module 3. The relative movement directions of the first glass 1 and the second glass 2 are opposite, and the distance change between the first concave curved surface 121 and the first convex curved surface 211 is the sum of the movement distances of the first glass 1 and the second glass 2. In addition, when the second glass 2 moves towards the camera module 3, the distance between the first convex curved surface 211 and the front end of the camera module 3 is shortened, which can reduce the propagation loss of light between the second glass 2 and the camera module 3. The second movement track 432 is a pre-designed rigid path. The second movement track 432 of the first movement assembly 43 can be a guide rail, a sliding groove, or a guide hole, etc. The third movement assembly 45 can comprise a sliding block, a protruding column, or a guide column, etc. The sliding block, the protruding column, or the guide column, etc. are embedded in the second movement track 432 and move along the second movement track 432, which can move the second glass 2 in a predetermined direction (e.g. the optical axis direction).

[0082] The second movement track 432 can be a second spiral track. The second spiral track can convert the rotational torque of the first movement assembly 43 into a linear thrust along the optical axis direction, thereby pushing the second glass 2. By rotating the motor in a forward direction or a reverse direction, the second glass 2 can be moved towards or away from the camera module 3, thereby changing the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2.

[0083] Optionally, the first spiral trajectory and the second spiral trajectory are opposite in rotation direction, so that the first glass 1 moves away from the lens of the camera module 3 while the second glass 2 moves towards the lens of the camera module 3.

[0084] In combination Figure 3 , Figure 4 , Figure 5 and Figure 6 , the power member 41 includes a motor, and the first movement assembly 43 includes a cam frame, and the motor can drive the cam frame to rotate around the optical axis, as shown in Figure 5 The first movement assembly 43 is provided with a first movement trajectory 431 and a second movement trajectory 432, the first movement trajectory 431 can be a first groove formed in the first movement assembly 43, and the second movement trajectory 432 can be a second groove formed in the first movement assembly 43; the guide frame 46 is fixed to the housing 6 of the electronic device, and the guide frame 46 is provided with a guide groove 461 extending along the Z direction, so that when the power member 41 drives the first movement assembly 43 to rotate, the second movement assembly 44 will not rotate with the first movement assembly 43, and the movement of the power member 41 is changed into linear movement, so that the first glass 1 can move towards or away from the second glass 2.

[0085] The second movement assembly 44 includes a concave mirror frame, and the first glass 1 is fixed to the concave mirror frame, and the concave mirror frame includes a first protruding portion, and the first protruding portion sequentially passes through the guide groove 461 and the first groove; when the motor drives the cam frame to rotate, due to the limiting action of the guide groove 461, the first protruding portion can move along the Z direction under the action of the first movement trajectory 431, so as to drive the first glass 1, so that the distance between the first concave surface 121 of the first glass 1 and the first convex surface 211 of the second glass 2 changes.

[0086] The third movement assembly 45 includes a convex mirror frame, and the second glass 2 is fixed to the convex mirror frame, and the convex mirror frame includes a second protruding portion, and the second protruding portion sequentially passes through the guide groove 461 and the second groove; when the motor drives the cam frame to rotate, due to the limiting action of the guide groove 461, the second protruding portion can move along the Z direction under the action of the second movement trajectory 432, so as to drive the second glass 2, so that the distance between the first convex surface 211 of the second glass 2 and the first concave surface 121 of the first glass 1 changes. In an embodiment, the convex mirror frame wraps the side surface of the second glass 2, which can improve the stability of the second glass 2.

[0087] In an embodiment, the electronic device comprises a camera module 3, a protective glass and a processor, the protective glass covers the lens of the camera module 3, the protective glass comprises a first glass 1 and a second glass 2, at least one of the first glass 1 and the second glass 2 is movable to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2. The processor is configured to: when the camera application meets a first trigger condition, control the first glass 1 and the second glass 2 to separate; and when the camera application meets a second trigger condition, control the first glass 1 and the second glass 2 to combine.

[0088] The first trigger condition can be a situation where the field of view needs to be expanded, and can include: a user clicking a field of view expansion virtual button on the screen; a user performing a zoom-out operation on the preview screen, etc.

[0089] The second trigger condition can be a situation where the original imaging range of the camera module 3 needs to be restored, and can include: a user clicking an exit field of view expansion mode virtual button on the screen; a user performing a zoom-in operation on the preview screen, etc.

[0090] When the camera application meets the first trigger condition, the processor controls the power member 41 to rotate in a first direction, the first direction can be the forward rotation direction (or the reverse rotation direction) of the motor, the power member 41 transmits power to the first motion assembly 43 through the transmission assembly, the first motion assembly 43 transmits power to the second motion assembly 44, the second motion assembly drives the first glass 1 to move away from the second glass 2, expanding the imaging range; when the camera application meets the second trigger condition, the processor controls the power member 41 to rotate in a direction opposite to the first direction, when the first direction is the forward rotation direction of the motor, the direction opposite to the first direction is the reverse rotation direction of the motor; when the first direction is the reverse rotation direction of the motor, the direction opposite to the first direction is the forward rotation direction of the motor. The power member 41 transmits power to the first motion assembly 43 through the transmission assembly, the first motion assembly 43 transmits power to the second motion assembly 44, the second motion assembly drives the first glass 1 to move towards the second glass 2, restoring the original imaging range of the camera module 3 itself.

[0091] When the camera application meets the first trigger condition, the processor controls the power component 41 to rotate in the first direction. The power component 41 transmits power to the first motion component 43 through the transmission assembly. The first motion component 43 transmits power to the second motion component 44 and the third motion component 45. The second motion component drives the first glass 1, and the third motion component 45 drives the second glass 2 to move the first glass 1 and the second glass 2 in a direction away from each other, expanding the imaging range. When the camera application meets the second trigger condition, the processor controls the power component 41 to rotate in the first direction. The power component 41 transmits power to the first motion component 43 through the transmission assembly. The first motion component 43 transmits power to the second motion component 44 and the third motion component 45. The second motion component drives the first glass 1, and the third motion component 45 drives the second glass 2 to move the first glass 1 and the second glass 2 in a direction close to each other, restoring the original imaging range of the camera module 3 itself.

[0092] In some embodiments, when the camera detects the need for a super-wide scene, such as when the camera recognizes a group photo, a large building, or an open landscape, the user clicks the super-wide mode button or there is uncaught scenery at the edge of the shot, the processor can automatically control the power component 41 to drive the first glass 1 and the second glass 2 apart to expand the imaging range. When the camera detects a scene switch to close-up, portrait shooting, insufficient light, or the user exits the super-wide mode, the processor automatically controls the power component 41 to combine the first glass 1 and the second glass 2, restoring the original imaging range of the camera module 3, ensuring the clarity of details in close-up shooting.

[0093] In some embodiments, when the lens focal length of the camera module 3 is adjusted to be shorter, reducing the imaging size of the objects being photographed in the picture, the processor can automatically control the power component 41 to drive the first glass 1 and the second glass 2 apart.

[0094] In some embodiments, the image sensor of the camera module 3 collects ambient light information and picture content and transmits the data to the processor. The processor analyzes the ambient light brightness and, when it is determined to be a strong light scene and the image recognition technology detects that the picture contains a large area of sky or a reflective area, the processor automatically sends a control instruction to the power component 41. The power component 41 receives the instruction and drives the first glass 1 away from the second glass 2 along the optical axis, causing them to separate. The protective glass switches to a composite optical structure, automatically turning on the super-wide mode. When the processor detects that the ambient light brightness is a weak light scene, it makes a judgment by analyzing the data transmitted by the image sensor and sends a reverse control instruction to the power component 41. The power component 41 drives the first glass 1 to approach the second glass 2 along the optical axis until they are attached or in close proximity. The protective glass does not change the shooting mode of the original optical path of the camera module 3, and the imaging quality remains the same as the original imaging range of the camera module 3.

[0095] In an embodiment, when shooting a distant scene, the processor can automatically control the power member 41 to drive the first glass 1 to separate from the second glass 2, so that the scene far away from the lens can be clearly included in the frame, and a wider space range can be accommodated. When shooting a medium scene, the processor can automatically control the power member 41 to drive the first glass 1 to separate from the second glass 2, that is, the distance between the first glass 1 and the second glass 2 is a value between the maximum distance of the first glass 1 and the second glass 2, so that the frame range and the detail clarity can be balanced. When shooting a close scene, the processor can automatically control the power member 41 to drive the first glass 1 to automatically combine with the second glass 2, so as to avoid the perspective distortion of the ultra-wide-angle close-up.

[0096] In an embodiment, when the camera detects that the number of people shooting is greater than or equal to a preset number, the processor can automatically control the power member 41 to drive the first glass 1 to separate from the second glass 2 to expand the field of view angle; when the camera detects that the number of people shooting is less than the preset number, the processor can automatically control the power member 41 to drive the first glass 1 to automatically combine with the second glass 2, so that the camera module 3 can focus on the face of the person, present clearer facial details, and improve the imaging effect when shooting a single person or a small number of people.

[0097] The protective glass provided by the embodiments of the present disclosure includes a first glass 1, a second glass 2, and a driver. At least one of the first glass 1 and the second glass 2 can move to change the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, and the first concave curved surface 121 and the first convex curved surface 211 are opposite; the driver is used to drive at least one of the first glass 1 and the second glass 2 to move. When the first glass 1 and the second glass 2 are closer, only the light with a smaller angle with the optical axis can enter the lens of the camera module 3, and at this time, the imaging range of the camera module 3 also correspondingly decreases; when the first glass 1 and the second glass 2 are farther away, the light with a larger angle with the optical axis can enter the lens of the camera module 3, the range of the light entering the lens becomes larger, and the imaging range of the camera module 3 also increases accordingly. The change of the distance between the first glass 1 and the second glass 2 can adjust the propagation path of the light passing through the first glass 1 and the second glass 2, so as to control the range of the incident angle of the light entering the lens and change the size of the scene range that can be captured by the camera module 3.

[0098] The driver drives one of the first glass 1 and the second glass 2 to move, so that the first glass 1 and the second glass 2 are separated. This separated structure can make more angle range of light enter the lens, which is equivalent to that the effective light receiving range of the camera module 3 is expanded, so that the field of view angle is expanded, and more wide frame information can be captured.

[0099] The greater the distance between the first glass 1 and the second glass 2, the wider the range of the light that can enter the lens of the camera module 3, and the larger the scene range that can be captured by the camera module 3.

[0100] In one specific implementation, combined with Figure 7 and Figure 8 As shown, the first concave surface 121 and the first convex surface 211 are complementary; the first surface 11 of the first glass 1 is a plane, the central region of the second surface 12 of the first glass 1 is the first concave surface 121, and the center point of the first concave surface 121 is located on the optical axis of the lens of the covered camera module; the central region of the third surface 21 of the second glass 2 is the first convex surface 211, and the center point of the first convex surface 211 is located on the optical axis of the lens of the covered camera module, and the fourth surface 22 of the second glass 2 is a plane. When the first glass 1 moves, the center point of the first concave surface 121 moves on the optical axis; when the second glass 2 moves, the center point of the first convex surface 211 moves on the optical axis. Whether the first glass 1 and the second glass 2 are attached, partially separated, or fully separated, the curvature centers of the first concave surface 121 and the first convex surface 211 can be completely aligned with the optical center of the camera module 3, making the light refraction path symmetrical and eliminating the optical deviation of the first glass 1 or the second glass 2 during the movement.

[0101] When the first concave surface 121 and the first convex surface 211 are strictly complementary, they completely match. The curvatures of the first concave surface 121 and the first convex surface 211 cancel each other out due to the complementary structure, weakening or even eliminating the ability of the protective glass to change the light propagation path (equivalent to the light propagation path without a protective glass). In this case, the light propagation path is not significantly affected when passing through the protective glass. It can be assumed that the light enters the lens of the camera module 3 at the same angle as without a protective glass. The imaging range of the camera module 3 is also unaffected (the same as the imaging range without a protective glass), and the camera module 3 maintains its original imaging range.

[0102] When the first glass 1 and the second glass 2 are separated, the first concave curved surface 121 and the first convex curved surface 211 are independent lenses, respectively. When the light first passes through the first concave curved surface 121 of the first glass 1, the light is deflected away from the center axis of the lens, thereby expanding the propagation angle of the light. Subsequently, the diffused light passes through the first convex curved surface 211 of the second glass 2 to adjust the angle and then enters the lens of the camera module 3. Compared with the state that the first glass 1 and the second glass 2 are attached, this separated structure can allow more light in a range of angles to enter the lens, which is equivalent to expanding the effective light receiving range of the camera module 3, thereby realizing the expansion of the field of view and capturing more extensive picture information. The greater the distance between the first glass 1 and the second glass 2, the wider the range of light that can enter the lens of the camera module 3, and the greater the range of scenes that the camera module 3 can capture. Therefore, the protective glass has not only the function of protecting the camera module 3 but also the function of optical adjustment. By adjusting the distance between the first concave curved surface 121 of the first glass 1 and the first convex curved surface 211 of the second glass 2, the function of a traditional independent ultra-wide-angle camera can be replaced, and there is no need to additionally equip an image sensor and corresponding circuit of an ultra-wide-angle camera, thereby saving space and reducing the use of the ultra-wide-angle camera, thereby reducing the assembly difficulty and potential failure risk of the device.

[0103] In an embodiment, after the first glass 1 and the second glass 2 are attached, a complete square glass can be formed, and the edges of the square structure can be completely attached to the frame of the electronic device shell 6.
