Description

Technical Field

[0001] This utility model relates to a camera module and an electronic device, and more particularly to a camera module suitable for electronic devices. Background Technology

[0002] With advancements in semiconductor technology, the performance of electronic image sensors has improved, allowing pixels to reach smaller sizes. Therefore, high-quality imaging lenses have become an indispensable component. Furthermore, with the rapid development of technology, mobile devices equipped with imaging lenses are being used more widely, leading to more diverse requirements for these lenses.

[0003] In existing camera modules, the imaging lens typically needs to move back and forth to find the optimal positioning position during autofocus or optical image stabilization. Due to the lack of a precise displacement detection mechanism, the imaging lens often needs to make multiple attempts, resulting in longer focusing or optical image stabilization times, reducing shooting efficiency and image quality. Furthermore, if not properly controlled, the imaging lens may move in the wrong direction during movement, leading to collisions and affecting the camera module's lifespan and shooting stability. While some technologies attempt to assist positioning using optical detection or computer calculations, the system architecture is complex and computationally expensive, hindering the miniaturization and cost control of camera modules. Therefore, providing a control technology that is simple in structure, accurate in positioning, and can effectively shorten autofocus and optical image stabilization times is a crucial area for improvement in existing technologies. Utility Model Content

[0004] In view of the above-mentioned problems, this utility model provides a camera module and electronic device, which solves the problems of complex system architecture and high computing resource requirements in the prior art, which are not conducive to the miniaturization and cost control of camera modules.

[0005] This invention provides a camera module comprising an imaging lens, a driving module, and a positioning module. The imaging lens has a central axis. The driving module drives the imaging lens to move along the central axis. The positioning module includes a positioning light source emitting module, a positioning light source receiving module, and a positioning light shield. The positioning light source receiving module receives emitted light from the positioning light source emitting module. The positioning light shield moves synchronously with the imaging lens. When the imaging lens moves along the central axis, the positioning light shield at least partially blocks the emitted light from the positioning light source emitting module, and the light intensity of the emitted light received by the positioning light source receiving module changes with the movement of the positioning light shield, and outputs a corresponding positioning signal according to the received light intensity.

[0006] This utility model also provides a camera module, which includes an imaging lens, an optical path reversing element, a driving module, and a positioning module. The imaging lens has a central axis. The optical path reversing element is disposed on the object side or image side of the imaging lens, and the optical path reversing element includes at least one reflective surface for reversing the optical path. The driving module is used to drive the optical path reversing element to move along the direction of the central axis. The positioning module includes a positioning light source emitting module, a positioning light source receiving module, and a positioning light shield. The positioning light source receiving module is used to receive emitted light from the positioning light source emitting module. The positioning light shield is used to move synchronously with the optical path reversing element. Wherein, when the optical path reversing element moves along the direction of the central axis, the positioning light shield at least partially blocks the emitted light from the positioning light source emitting module, and the light intensity of the emitted light received by the positioning light source receiving module changes with the movement of the positioning light shield, and outputs a corresponding positioning signal according to the received light intensity.

[0007] This utility model also provides a camera module, which includes an imaging lens, a driving module, a first positioning module, and a second positioning module. The imaging lens has a central axis. The driving module is used to drive the imaging lens to move along a first direction and / or a second direction, the first direction being different from the second direction, and both the first and second directions being perpendicular to the central axis. The first positioning module includes a first positioning light source emitting module, a first positioning light source receiving module, and a first positioning light shield. The first positioning light source receiving module is used to receive a first emitted light from the first positioning light source emitting module. The first positioning light shield is used to move synchronously with the imaging lens. The second positioning module includes a second positioning light source emitting module, a second positioning light source receiving module, and a second positioning light shield. The second positioning light source receiving module is used to receive a second emitted light from the second positioning light source emitting module. The second positioning light shield is used to move synchronously with the imaging lens. When the imaging lens moves along a first direction, the first positioning light-blocking plate at least partially blocks the first emitted light from the first positioning light source emitting module, and the first light intensity of the first emitted light received by the first positioning light source receiving module changes with the movement of the first positioning light-blocking plate, and outputs a corresponding first signal according to the received first light intensity. When the imaging lens moves along a second direction, the second positioning light-blocking plate at least partially blocks the second emitted light from the second positioning light source emitting module, and the second light intensity of the second emitted light received by the second positioning light source receiving module changes with the movement of the second positioning light-blocking plate, and outputs a corresponding second signal according to the received second light intensity.

[0008] This invention provides an electronic device that includes the aforementioned camera module.

[0009] According to the camera module and electronic device disclosed in this utility model, the light intensity sensed by the positioning light source receiving module can change as the positioning light-blocking plate moves, thanks to the configuration of the positioning module. This structure is not only simple but also eliminates the need for complex computer calculations. The displacement of the imaging lens or optical path deflection element can be determined by the change in light intensity measured by the positioning light source receiving module or the change in voltage output by the light blocker.

[0096] The following detailed description of the features and advantages of this utility model in the embodiments is sufficient to enable any person skilled in the art to understand the technical content of this utility model and implement it accordingly. Based on the disclosure of this specification, the scope of the claims, and the accompanying drawings, any person skilled in the art can easily understand the related objectives and advantages of this utility model. The following embodiments further illustrate the viewpoints of this utility model in detail, but are not intended to limit the scope of this utility model in any way.

[0097] This invention provides a camera module comprising an imaging lens, a driving module, and at least one positioning module. The imaging lens has a central axis. The camera module may also optionally include an optical path reversing element, which is disposed on the object side or image side of the imaging lens. The optical path reversing element includes at least one reflective surface for reversing the optical path. The driving module is used to drive the imaging lens or the optical path reversing element to move along the direction of the central axis, or the driving module is used to drive the imaging lens to move along a first direction and / or a second direction that are different from each other and perpendicular to the central axis. The positioning module is used to confirm the displacement of the imaging lens or the optical path reversing element. The driving module may be, for example, a stepper motor, a servo motor, or a voice coil motor, but this invention is not limited thereto. The positioning module may be, for example, a light interruptor, but this invention is not limited thereto.

[0098] In an embodiment where the driving module drives the imaging lens to move along the central axis, the camera module can be an autofocus camera module, and the at least one positioning module is used to confirm the displacement of the imaging lens along the central axis. The number of the at least one positioning module can be one. The positioning module includes a positioning light source emitting module, a positioning light source receiving module, and a positioning light shield. The positioning light source receiving module receives emitted light from the positioning light source emitting module, and the positioning light shield moves synchronously with the imaging lens. When the imaging lens moves along the central axis, the positioning light shield at least partially blocks the emitted light from the positioning light source emitting module, and the light intensity of the emitted light received by the positioning light source receiving module changes with the movement of the positioning light shield, outputting a corresponding positioning signal according to the received light intensity. This allows the positioning module to accurately determine the position of the imaging lens, reducing the reciprocating focus-finding process of the imaging lens, thereby shortening the focusing time and preventing collisions caused by reverse movement of the imaging lens.

[0099] The area of ​​the positioning light-blocking plate that blocks the emitted light can be gradually changed along the central axis. In this way, as the positioning light-blocking plate moves synchronously with the imaging lens, the area of ​​the positioning light-blocking plate that blocks the emitted light gradually changes, thereby detecting the displacement of the imaging lens.

[0100] The positioning light-shielding plate may include a light-shielding plate body and a hollow structure. The hollow structure penetrates the light-shielding plate body and allows some of the emitted light from the positioning light source emitting module to pass through. Therefore, the hollow structure can be considered as optical encoding; by changing the spacing or length of the hollow structure to adjust the encoding information, the displacement of the imaging lens can be accurately obtained. The hollow structure may be, for example, a central hollow, or a hollow stripe with straight or horizontal bars, but this invention is not limited to these forms.

[0101] The light transmittance of the positioning light-blocking plate can be gradually changed along a direction parallel to the central axis. This allows the positioning light-blocking plate to be formed as a continuously adjustable neutral density filter, so that during the synchronous movement of the positioning light-blocking plate and the imaging lens, different degrees of light intensity changes can be provided to the light source receiving module to detect the displacement of the imaging lens. The shape of the continuously adjustable neutral density filter can be, for example, circular or rectangular, but this invention is not limited thereto.

[0102] The camera module may further include a light shield extending from the top of the positioning light source emitting module and the top of the positioning light source receiving module toward the positioning light shield, and the light shield is used to block ambient light outside the positioning module. Therefore, in the embodiment where the positioning module is a light interruptor, since the light interruptor is prone to detection errors due to ambient light, a light shield can be designed to reduce interference from external ambient light sources.

[0103] The camera module may further include a first light-shielding slot and a second light-shielding slot, wherein the first light-shielding slot is used to accommodate the positioning light source emitting module, and the second light-shielding slot is used to accommodate the positioning light source receiving module. By housing the positioning light source emitting module and the positioning light source receiving module within the light-shielding slots, the influence of ambient light can be further reduced.

[0104] The positioning light source emitting module may include multiple light source emitting units, and these light source emitting units may be arranged in an array. Therefore, by forming an array light source emitting module from multiple light source emitting units, the light detection range of the positioning module can be increased. For example, the light source emitting module may be a rectangular array or a circular array, but this invention is not limited thereto.

[0105] The positioning light source emitting module may include a strip-shaped light source emitting unit, and the strip-shaped light source emitting unit is positioned perpendicular to the central axis. This increases the light detection range of the positioning module.

[0106] The camera module may further include a calibration module, which may include a calibration light source emitting module, a calibration light source receiving module, and a calibration light shield. The calibration light source receiving module receives calibration light from the calibration light source emitting module. The calibration light shield moves synchronously with the imaging lens. When the imaging lens moves along its central axis to an origin position, the calibration light shield blocks the calibration light from the calibration light source emitting module, and the calibration light source receiving module outputs a corresponding calibration signal. Thus, the calibration module can check for errors in the displacement measured by the positioning module of the imaging lens, and correct any errors immediately. The calibration light shield may be rectangular, but this invention is not limited thereto. When the imaging lens moves along its central axis to the origin position, the calibration light shield, for example, completely blocks the calibration light from the calibration light source emitting module, and the calibration light source receiving module, for example, outputs a corresponding calibration signal when it does not receive calibration light.

[0107] In a direction parallel to the central axis, the distance between the correction light source receiving module and the correction shackle can be greater than the distance between the positioning light source receiving module and the positioning shackle. With this configuration, during the focusing process of the imaging lens, the positioning shackle gradually blocks the positioning light source receiving module first, and the system begins recording the displacement of the imaging lens accordingly. Subsequently, the correction shackle blocks the correction light source receiving module to correct the displacement measured by the positioning module. By blocking the correction light source receiving module later, the positioning module can be corrected, thereby obtaining a more accurate imaging lens position.

[0108] The camera module may further include a storage unit for storing the displacement of the imaging lens. This prevents the system from being unable to determine the position of the imaging lens after a restart in the event of an unexpected power outage during the operation of the drive module.

[0109] The imaging lens may also include multiple lens groups, and the drive module may be used, for example, to drive one of the lens groups (i.e., the movable lens group) for focusing, but this invention is not limited thereto. In an embodiment where the drive module is used to drive the movable lens group of the imaging lens, the positioning module is used to confirm the displacement of the movable lens group in the direction along the central axis, and the positioning light shield is used to move synchronously with the movable lens group of the imaging lens.

[0110] In an embodiment where the driving module drives the optical path reversing element to move along the central axis, the camera module can be an autofocus camera module, and the at least one positioning module is used to confirm the displacement of the optical path reversing element along the central axis. The number of the at least one positioning module can be one. The positioning module includes a positioning light source emitting module, a positioning light source receiving module, and a positioning light shield. The positioning light source receiving module receives emitted light from the positioning light source emitting module. The positioning light shield moves synchronously with the optical path reversing element. When the optical path reversing element moves along the central axis, the positioning light shield at least partially blocks the emitted light from the positioning light source emitting module, and the light intensity of the emitted light received by the positioning light source receiving module changes with the movement of the positioning light shield, and outputs a corresponding positioning signal according to the received light intensity. Therefore, the position of the optical path reversing element can be accurately obtained through the positioning module, thereby reducing the reciprocating motion of the optical path reversing element during the process of finding the focus of the imaging lens, thus shortening the focusing time, and preventing collisions caused by the optical path reversing element due to reverse movement.

[0111] The optical path deflection element can be a single prism, but this invention is not limited thereto. In some embodiments, the optical path deflection element can be composed of multiple prisms. Additionally, in some embodiments, the optical path deflection element can be a mirror.

[0112] The area of ​​the positioning light-blocking plate that blocks the emitted light can be gradually changed along the central axis. In this way, as the positioning light-blocking plate and the optical path reversing element move synchronously, the area of ​​the positioning light-blocking plate that blocks the emitted light gradually changes, thereby detecting the displacement of the optical path reversing element.

[0113] The positioning light-shielding plate may include a light-shielding plate body and a hollow structure. The hollow structure penetrates the light-shielding plate body and allows some of the emitted light from the positioning light source emitting module to pass through. Therefore, the hollow structure can be considered as optical encoding. By changing the spacing or length of the hollow structure to adjust the encoding information, the displacement of the optical path turning element can be accurately obtained. The hollow structure may be, for example, a central hollow, or a hollow stripe with straight or horizontal bars, but this invention is not limited to these forms.

[0114] The light transmittance of the positioning light-shielding plate can be gradually changed along a direction parallel to the central axis. This allows the positioning light-shielding plate to be formed as a continuously adjustable neutral density filter. As the positioning light-shielding plate and the optical path reversing element move synchronously, different degrees of light intensity changes can be provided to the light source receiving module, thereby detecting the displacement of the optical path reversing element. The shape of the continuously adjustable neutral density filter can be, for example, circular or rectangular, but this invention is not limited thereto.

[0115] The camera module may further include a light shield extending from the top of the positioning light source emitting module and the top of the positioning light source receiving module toward the positioning light shield, and the light shield is used to block ambient light outside the positioning module. Therefore, in the embodiment where the positioning module is a light interruptor, since the light interruptor is prone to detection errors due to ambient light, a light shield can be designed to reduce interference from external ambient light sources.

[0116] The camera module may further include a first light-shielding slot and a second light-shielding slot, wherein the first light-shielding slot is used to accommodate the positioning light source emitting module, and the second light-shielding slot is used to accommodate the positioning light source receiving module. By housing the positioning light source emitting module and the positioning light source receiving module within the light-shielding slots, the influence of ambient light can be further reduced.

[0117] The positioning light source emitting module may include multiple light source emitting units, and these light source emitting units may be arranged in an array. Therefore, by forming an array light source emitting module from multiple light source emitting units, the light detection range of the positioning module can be increased. For example, the light source emitting module may be a rectangular array or a circular array, but this invention is not limited thereto.

[0118] The positioning light source emitting module may include a strip-shaped light source emitting unit, and the strip-shaped light source emitting unit is positioned perpendicular to the central axis. This increases the light detection range of the positioning module.

[0119] The camera module may further include a calibration module, which may include a calibration light source emitting module, a calibration light source receiving module, and a calibration light shield. The calibration light source receiving module receives calibration light from the calibration light source emitting module. The calibration light shield moves synchronously with the optical path reversing element. Specifically, when the optical path reversing element moves along the central axis to an origin position, the calibration light shield blocks the calibration light from the calibration light source emitting module, and the calibration light source receiving module outputs a corresponding calibration signal. Thus, the calibration module can check whether there is an error in the displacement measurement of the optical path reversing element by the positioning module, and can correct it immediately if an error is confirmed. The calibration light shield may be rectangular, but this invention is not limited to this.

[0120] The optical path reversing element may include at least two reflective surfaces, and the optical path reversing element is used to reverse the optical path multiple times. In this way, in an embodiment where the optical path reversing element has multiple reflective surfaces, the optical path can be reversed multiple times.

[0121] In an embodiment where the driving module drives the imaging lens to move along mutually different directions and / or second directions, both perpendicular to the central axis, the camera module can be an optical image stabilization camera module, and the at least one positioning module is used to confirm the displacement of the imaging lens along the first and / or second directions. The number of the at least one positioning module can be two, namely a first positioning module and a second positioning module. The first positioning module includes a first positioning light source emitting module, a first positioning light source receiving module, and a first positioning light shield. The first positioning light source receiving module receives first emitted light from the first positioning light source emitting module. The first positioning light shield moves synchronously with the imaging lens. The second positioning module includes a second positioning light source emitting module, a second positioning light source receiving module, and a second positioning light shield. The second positioning light source receiving module receives second emitted light from the second positioning light source emitting module. The second positioning light shield moves synchronously with the imaging lens. When the imaging lens moves along a first direction, the first positioning light-blocking plate at least partially blocks the first emitted light from the first positioning light source emitting module, and the first light intensity of the first emitted light received by the first positioning light source receiving module changes with the movement of the first positioning light-blocking plate, and outputs a corresponding first signal according to the received first light intensity. When the imaging lens moves along a second direction, the second positioning light-blocking plate at least partially blocks the second emitted light from the second positioning light emitting module, and the second light intensity of the second emitted light received by the second positioning light receiving module changes with the movement of the second positioning light-blocking plate, and outputs a corresponding second signal according to the received second light intensity. This allows for precise determination of the imaging lens position using the first and second positioning modules, thereby reducing the reciprocating motion of the imaging lens and shortening the positioning time during optical image stabilization.

[0122] The light transmittance of at least one of the first and second positioning light-blocking plates can be gradually changed along the moving direction of the imaging lens. Therefore, the movement of the imaging lens can be detected by the change in the light transmittance of at least one positioning light-blocking plate in the moving direction of the imaging lens.

[0123] The camera module may further include a first light shield and a second light shield. The first light shield extends from the top of the first positioning light emitting module and the top of the first positioning light receiving module toward the first positioning light shield, and is used to block ambient light outside the first positioning module. Similarly, the second light shield extends from the top of the second positioning light emitting module and the top of the second positioning light receiving module toward the second positioning light shield, and is used to block ambient light outside the second positioning module. Therefore, in the embodiment where the positioning module is a light interruptor, since the light interruptor is prone to detection errors due to ambient light, a light shield can be designed to reduce interference from external ambient light sources.

[0124] The camera module may further include a first light-shielding slot and a second light-shielding slot. The first light-shielding slot is used to accommodate a first positioning light source emitting module and a first positioning light source receiving module. The second light-shielding slot is used to accommodate a second positioning light source emitting module and a second positioning light source receiving module. By housing the positioning light source emitting module and the positioning light source receiving module in the light-shielding slot, the influence of ambient light can be further reduced. Furthermore, by placing the first positioning light source emitting module and the first positioning light source receiving module on the same side of the moving path of the first positioning light-shielding plate, the first positioning light source emitting module and the first positioning light source receiving module can share the first light-shielding slot. Similarly, by placing the second positioning light source emitting module and the second positioning light source receiving module on the same side of the moving path of the second positioning light-shielding plate, the second positioning light source emitting module and the second positioning light source receiving module can share the second light-shielding slot.

[0125] The first and second positioning light source emitting modules may each contain multiple light source emitting units, and these light source emitting units are arranged in an array. Therefore, the array light source emitting module composed of multiple light source emitting units can increase the light detection range of the positioning module. For example, the light source emitting module can be a rectangular array or a circular array, but this invention is not limited thereto.

[0126] The first and second positioning light source emitting modules may each include a strip-shaped light source emitting unit, and the strip-shaped light source emitting unit is positioned perpendicular to the central axis. This increases the light detection range of the positioning module.

[0127] The positioning light source receiving module in the positioning module may be, for example, a photodiode or a photoresistor, but this invention is not limited thereto.

[0128] In the same positioning module, the positioning light source emitting module and the positioning light source receiving module can be located on the same side or opposite sides of the moving path of the positioning light shield, but this utility model is not limited thereto. In particular, when the positioning light source emitting module and the positioning light source receiving module are designed to be located on the same side of the moving path of the positioning light shield, it is beneficial to reduce the size of the camera module.

[0129] The positioning light source emitting module can be ultraviolet light, infrared light or visible light, but this utility model is not limited to this.

[0130] According to the camera module disclosed in this utility model, the configuration of the positioning module allows the light intensity sensed by the positioning light source receiving module to change as the positioning light-blocking plate moves. This structure is not only simple but also eliminates the need for complex computer calculations. The displacement of the imaging lens or optical path deflection element can be determined by the change in light intensity measured by the positioning light source receiving module or the change in voltage output by the light blocker.

[0131] This invention provides an electronic device that includes the aforementioned camera module.

[0132] The various technical features disclosed in the camera module of this utility model can be combined and configured to achieve the corresponding effects.

[0133] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0134] <First Embodiment>

[0135] Please refer to Figures 1 to 7 ,in Figure 1 A perspective view of a camera module according to a first embodiment of the present invention is shown. Figure 2 Draw Figure 1 An exploded view of the camera module. Figure 3 Draw Figure 1 An enlarged schematic diagram of region A3. Figure 4 Draw Figure 1 A front view diagram of the camera module. Figure 5 Draw Figure 4 An enlarged view of area A5. Figure 6 Draw Figure 1 A side view of the camera module, and Figure 7 Draw Figure 6 An enlarged view of region A7.

[0136] In this embodiment, the camera module 1 is an autofocus camera module, and the camera module 1 includes a drive module 10, a printed circuit board 11, a movable carrier 12, an imaging lens 13, a positioning module 14, and a storage unit 15.

[0137] The drive module 10 is electrically connected to the printed circuit board 11, and the drive module 10 is disposed on the printed circuit board 11, for example, by a fixing member F1 and a flexible printed circuit board 16.

[0138] The imaging lens 13 has a central axis CA and is mounted on the movable carrier 12. The drive module 10 is used to drive the movable carrier 12 to move along the direction of the central axis CA, thereby causing the imaging lens 13 to move synchronously along the direction of the central axis CA.

[0139] The positioning module 14 includes a positioning light source emitting module 140, a positioning light source receiving module 141, and a positioning light shield 142. Both the positioning light source emitting module 140 and the positioning light source receiving module 141 are fixedly mounted on the printed circuit board 11 and electrically connected to it. The positioning light source receiving module 141 is used to receive the emitted light from the positioning light source emitting module 140.

[0140] The positioning light shield 142 is used to move synchronously with the imaging lens 13. Specifically, the positioning light shield 142 is fixed to the movable carrier 12, so that the positioning light shield 142 can move synchronously with the movable carrier 12 and the imaging lens 13. Furthermore, the positioning light shield 142 is movably located on one side of the positioning light source emitting module 140, so that the positioning light shield 142 can at least partially block the emitted light of the positioning light source emitting module 140. In addition, the positioning light shield 142 is designed to be approximately triangular in shape, tapering along a direction parallel to the central axis CA.

[0141] like Figure 3 , Figure 5 and Figure 7 As shown, the positioning light source emitting module 140 and the positioning light source receiving module 141 are positioned on opposite sides of the moving path of the positioning light shield 142. When the driving module 10 drives the movable carrier 12 to move along the central axis CA, the positioning light shield 142 and the imaging lens 13 move synchronously with the movable carrier 12. Because the positioning light shield 142 is approximately triangular in design, the area of ​​the positioning light shield 142 that blocks the emitted light gradually changes along the central axis CA. Therefore, the light intensity of the emitted light received by the positioning light source receiving module 141 changes with the movement of the positioning light shield 142, and the positioning light source receiving module 141 outputs a corresponding positioning signal according to the received light intensity.

[0142] For example, please refer to Figure 8 The diagram illustrates the curves showing how the positioning light source receiving module outputs corresponding positioning signals based on the received light intensity when the positioning light-shielding plate moves at different displacements. When the positioning light-shielding plate 142 moves synchronously with the imaging lens 13 and the movable carrier 12, it will have different blocking areas on the emitted light from the positioning light source emitting module 140. Thus, the positioning light source receiving module 141 will receive different light intensities and output corresponding voltages as corresponding positioning signals. Figure 8 As shown, the displacement of the positioning light shield 142 can be deduced from the voltage value of the corresponding positioning signal output by the positioning light source receiving module 141, and thus the displacement of the imaging lens 13 can be confirmed.

[0143] The storage unit 15 is disposed on the printed circuit board 11, and the storage unit 15 is used to store the displacement of the imaging lens 13.

[0144] In some embodiments, the camera module also includes a correction module to check for errors in the positioning module's measurement of the imaging lens's displacement, and to correct any errors immediately upon confirmation. For example, please refer to... Figure 9 The diagram illustrates a structural configuration of a camera module according to one embodiment of the present invention. Figure 9The camera module 1a is similar to the aforementioned camera module 1, one difference being that... Figure 9 The camera module 1a also includes a calibration module 17a.

[0145] The calibration module 17a includes a calibration light source emitting module 170a, a calibration light source receiving module 171a, and a calibration light shield 172a. Both the calibration light source emitting module 170a and the calibration light source receiving module 171a are fixedly mounted on and electrically connected to the printed circuit board 11a. The calibration light source receiving module 171a receives calibration light from the calibration light source emitting module 170a.

[0146] The correction shading plate 172a is used to move synchronously with the imaging lens 13a. Specifically, the correction shading plate 172a is fixed to a movable carrier, so that the correction shading plate 172a can move synchronously with the movable carrier and the imaging lens 13a. Furthermore, the correction shading plate 172a is movably located on one side of the correction light source emitting module 170a, so that the correction shading plate 172a can block the correction light from the correction light source emitting module 170a. When the imaging lens 13a moves to an origin position along the central axis CA, the correction shading plate 172a blocks the correction light from the correction light emitting module 170a, and the correction light source receiving module 171a outputs a corresponding correction signal.

[0147] like Figure 9 As shown, in the direction parallel to the central axis CA, the distance between the correction light source receiving module 171a and the correction light shield 172a is greater than the distance between the positioning light source receiving module 141a and the positioning light shield 142a.

[0148] in addition, Figure 9 Camera module 1a and Figure 1 Another difference between the camera modules is that Figure 9 The imaging lens 13a of the camera module 1a includes multiple lens groups 130a and 131a, and the drive module is used to drive one of the lens groups 130a for focusing. Specifically, the imaging lens 13a includes a movable lens group 130a and a fixed lens group 131a arranged sequentially along the central axis CA. The fixed lens group 131a is located between the movable lens group 130a and an image sensor MS1, and there is no relative displacement between the fixed lens group 131a and the image sensor MS1. The drive module is used to drive the movable lens group 130a to move along the central axis CA for focusing. Furthermore, the positioning module 14a and the correction module 17a are used to move synchronously with the movable lens group 130a of the imaging lens 13a, wherein the positioning module 14a is used to confirm the amount of displacement of the movable lens group 130a in the direction along the central axis CA.

[0149] In some embodiments, the camera module also includes a light shield to block ambient light from entering the positioning module. For example, please refer to... Figure 10 Its illustration Figure 1 A schematic diagram of one embodiment of the positioning module and light shield of the camera module. Figure 10 In the embodiment, the camera module 1b also includes a light shield 18b, which extends from the top of the positioning light source emitting module 140b and the top of the positioning light source receiving module 141b toward the positioning light shield 142b, and the light shield 18b is used to block the ambient light EL1 outside the positioning module 14b.

[0150] In addition, such as Figure 10 As shown, the camera module 1b also includes a first light-shielding slot 191b and a second light-shielding slot 192b. The first light-shielding slot 191b is used to accommodate the positioning light source emitting module 140b, and the second light-shielding slot 192b is used to accommodate the positioning light source receiving module 141b. Furthermore, the positioning light source emitting module 140b and the positioning light source receiving module 141b can be electrically connected to a printed circuit board via the output terminal T1.

[0151] exist Figure 10 In the embodiment, the positioning light source emitting module 140b and the positioning light source receiving module 141b of the positioning module 14b are located on opposite sides of the moving path of the positioning light shield 142b, but this utility model is not limited thereto. For example, please refer to... Figure 11 Its illustration Figure 1 A schematic diagram of another embodiment of the camera module's positioning module and light shield. Figure 11 In this embodiment, the positioning light source emitting module 140c and the positioning light source receiving module 141c of the positioning module 14c are located on the same side of the moving path of the positioning light shield 142c. The positioning light shield 142c is used, for example, to reflect the emitted light L1 from the positioning light source emitting module 140c to the positioning light source receiving module 141c. The positioning light shield 142c is designed to be approximately triangular in shape, tapering along a direction parallel to the central axis. Therefore, the reflective area of ​​the positioning light shield 142c for the emitted light L1 gradually changes along the central axis. Consequently, the light intensity of the emitted light L1 received by the positioning light source receiving module 141c changes as the positioning light shield 142c moves, and the positioning light source receiving module 141c outputs a corresponding positioning signal based on the received light intensity.

[0152] exist Figure 11In one embodiment, the positioning light source emitting module 140c and the positioning light source receiving module 141c are respectively housed in the first light-shielding groove 191c and the second light-shielding groove 192c. That is, the positioning light source emitting module 140c and the positioning light source receiving module 141c are housed in different light-shielding grooves, but this utility model is not limited thereto. In other embodiments, when the positioning light source emitting module and the positioning light source receiving module are disposed on the same side of the moving path of the positioning light-shielding plate, the positioning light source emitting module and the positioning light source receiving module can also be housed in the same light-shielding groove.

[0153] In addition, such as Figure 11 As shown, the light shield 18c extends from the top of the positioning light source emitting module 140c and the positioning light source receiving module 141c toward the positioning light shield 142c.

[0154] exist Figure 10 In some embodiments, the positioning light source emitting module 140b may include multiple light source emitting units arranged along the central axis, or it may include only one light source emitting unit, but this invention is not limited thereto. For example, in some embodiments, the positioning light source emitting module may include a strip-shaped light source emitting unit, and the direction in which the strip-shaped light source emitting unit is arranged is perpendicular to the central axis.

[0155] For another example, please refer to Figure 12 and Figure 13 ,in Figure 12 Draw Figure 1 A schematic diagram of another embodiment of the positioning module of the camera module, and Figure 13 Draw Figure 12 A schematic diagram illustrating the operation of the positioning light-shielding plate in the positioning module. Figure 12 and Figure 13 In the embodiment, the positioning light source emitting module 140d of the positioning module 14d includes multiple light source emitting units, and these light source emitting units are arranged in an array. Additionally, as... Figure 13 As shown, the light detection range R1 of the positioning light source receiving module 141d of the positioning module 14d can correspond to the configuration range of these light source emitting units of the positioning light source emitting module 140d.

[0156] like Figure 13 As shown, the positioning light-shielding plate 142d is designed to gradually taper along an axial direction D1 parallel to the central axis, forming approximately an isosceles triangle. Therefore, as the positioning light-shielding plate 142d moves along a direction parallel to the central axis, the area of ​​the positioning light-shielding plate 142d that blocks the emitted light gradually changes along the central axis. However, this utility model does not... Figure 13 The presented embodiment of the positioning light-shielding plate 142d is limited to this example. For instance, please refer to... Figures 14 to 22 They are drawn respectively Figure 12 Schematic diagrams of different implementations of the positioning light shield of the positioning module.

[0157] exist Figure 14 In the illustrated embodiment, the positioning light-shielding plate 142e is designed to gradually expand along the axial movement direction D1, forming an approximately isosceles triangle. Therefore, as the positioning light-shielding plate 142e moves in a direction parallel to the central axis, the area of ​​the light-shielding plate 142e that blocks the emitted light gradually changes along the central axis, allowing the light detection range R1 of the positioning light source receiving module 141e to detect different light intensities. It should be noted that the positioning light-shielding plate only needs to pass through the light detection range of the positioning light source receiving module; this invention is not limited by the installation direction and position of the positioning module.

[0158] exist Figure 15 In the embodiment shown, the shape of the positioning light shield 142f is designed to gradually shrink along the axial moving direction D1 and be approximately a right-angled triangle. Thus, when the positioning light shield 142f moves in a direction parallel to the central axis, the shielding area of ​​the positioning light shield 142f on the emitted light will gradually change along the central axis, so that the light detection range R1 of the positioning light source receiving module 141f can detect different light intensities.

[0159] exist Figure 16 In the embodiment shown, the positioning light shield 142g is designed to be approximately semi-elliptical, gradually shrinking along the axial moving direction D1. As the positioning light shield 142g moves in a direction parallel to the central axis, the shielding area of ​​the positioning light shield 142g on the emitted light will gradually change along the central axis, so that the light detection range R1 of the positioning light source receiving module 141g can detect different light intensities.

[0160] exist Figure 17 In the embodiment shown, the positioning light shield 142h is designed to be at least partially circular, so that when the positioning light shield 142h moves in a direction parallel to the central axis, the shielding area of ​​the positioning light shield 142h on the emitted light will gradually change in the direction of the central axis, so that the light detection range R1 of the positioning light source receiving module 141h can detect different light intensities.

[0161] exist Figure 18In the embodiment shown, the positioning light shield 142i includes a light shield body 1420i and a hollow structure 1421i. The hollow structure 1421i is hollow in the middle and penetrates through the light shield body 1420i. The shape of the hollow structure 1421i is designed to gradually shrink along the axial moving direction D1 and is approximately an isosceles triangle. The hollow structure 1421i is used to allow part of the emitted light from the positioning light source emitting module to pass through. Thus, when the positioning light shield 142i moves in a direction parallel to the central axis, the blocking area of ​​the positioning light shield 142i on the emitted light will gradually change along the central axis, so that the light detection range R1 of the positioning light source receiving module 141i can detect different light intensities.

[0162] exist Figure 19 In the embodiment shown, the positioning light shield 142j includes a light shield body 1420j and a hollow structure 1421j. The shape of the light shield body 1420j is designed to gradually shrink along the axial moving direction D1 and is approximately an isosceles triangle. The hollow structure 1421j consists of multiple horizontal hollow stripes perpendicular to the central axis and penetrating the light shield body 1420j to allow some of the emitted light from the positioning light source emitting module to pass through. Thus, when the positioning light shield 142j moves in a direction parallel to the central axis, the blocking area of ​​the positioning light shield 142j for the emitted light will gradually change along the central axis, so that the light detection range R1 of the positioning light source receiving module 141j can detect different light intensities.

[0163] exist Figure 20 In the embodiment shown, the positioning light shield 142k includes a light shield body 1420k and a hollow structure 1421k. The shape of the light shield body 1420k is designed to gradually shrink along the axial moving direction D1 and is approximately an isosceles triangle. The hollow structure 1421k consists of multiple straight hollow stripes parallel to the central axis and penetrating the light shield body 1420k to allow some of the emitted light from the positioning light source emitting module to pass through. Thus, when the positioning light shield 142k moves in a direction parallel to the central axis, the blocking area of ​​the positioning light shield 142k for the emitted light will gradually change along the central axis, so that the light detection range R1 of the positioning light source receiving module 141k can detect different light intensities.

[0164] exist Figure 21 In the illustrated embodiment, the positioning light-shielding plate 142m is a rectangular progressive light-shielding plate, and the light transmittance of the positioning light-shielding plate 142m gradually changes along a direction parallel to the central axis. Specifically, the light transmittance of the positioning light-shielding plate 142m gradually increases, for example, along the axial movement direction D1. Therefore, when the positioning light-shielding plate 142m moves along a direction parallel to the central axis, the blocking rate of the positioning light-shielding plate 142m for the emitted light gradually changes along the central axis, causing the light detection range R1 of the positioning light source receiving module 141m to detect different light intensities.

[0165] exist Figure 22 In the illustrated embodiment, the positioning light-shielding plate 142n is a circular progressive light-shielding plate. The positioning light-shielding plate 142n overlaps with the light detection range R1 of the positioning light source receiving module 141n, and the axis C1 of the positioning light-shielding plate 142n is offset from the center C2 of the light detection range R1. The light transmittance of the positioning light-shielding plate 142n gradually changes in its circumferential direction. When the movable carrier and imaging lens move along the central axis, the positioning light-shielding plate 142n can rotate in a rotational direction D2, causing areas of the positioning light-shielding plate 142n with different light transmittances to overlap with the light detection range R1.

[0166] <Second Embodiment>

[0167] Please refer to Figures 23 to 26 ,in Figure 23 A front view schematic diagram of a camera module according to a second embodiment of the present invention is shown. Figure 24 Draw Figure 23 An exploded view of the camera module. Figure 25 Draw Figure 23 An enlarged schematic diagram of area A25, and Figure 26 Draw Figure 23 A schematic diagram of the section along section line 26-26.

[0168] In this embodiment, the camera module 2 is an autofocus camera module, and the camera module 2 includes a drive module 20, a fixed base 21, a movable carrier 22, an imaging lens 23, a positioning module 24, two brackets 25, an optical path deflection element 26, and an image sensor 27.

[0169] The imaging lens 23 has a central axis CA, and the optical path deflection element 26 is disposed on the image side of the imaging lens 23, and the optical path deflection element 26 is located between the imaging lens 23 and the image sensor 27 in the imaging optical path. Figure 26 As shown, the optical path deflection element 26 includes three reflective surfaces 261, 262 and 263 for multiple deflections of the optical path to deflect light from the imaging lens 23 to the image sensor 27.

[0170] The two supports 25 are disposed in the fixed base 21, and the movable carrier 22 is movably disposed in the fixed base 21. The optical path conversion element 26 is mounted on the movable carrier 22. The two supports 25 are located between the movable carrier 22 and the fixed base 21, and the two supports 25 can support the movable carrier 22 and the optical path conversion element 26, and can prevent the movable carrier 22 and the optical path conversion element 26 from colliding with the fixed base 21 during movement.

[0171] The drive module 20 drives the movable carrier 22 to move along the central axis CA, thereby causing the optical path deflection element 26 to move synchronously along the central axis CA. Specifically, the drive module 20 includes a coil 200, a magnet 201, and multiple rolling elements 202. The coil 200 is disposed on the fixed base 21, the magnet 201 is fixed to the movable carrier 22, and the rolling elements 202 are rotatably disposed in four guide grooves G1 formed between the movable carrier 22 and the fixed base 21. These guide grooves G1 extend in a direction parallel to the central axis CA. The drive module 20 drives the movable carrier 22 to move by the electromagnetic driving force generated between the coil 200 and the magnet 201 after the coil 200 is energized, and guides the movable carrier 22 together with the optical path deflection element 26 along the central axis CA through the cooperation of the rolling elements 202 and the guide grooves G1. In this embodiment, these rolling elements 202 are spherical balls, but this invention is not limited to this.

[0172] The positioning module 24 includes a positioning light source emitting module 240, a positioning light source receiving module 241, and a positioning light shield 242. Both the positioning light source emitting module 240 and the positioning light source receiving module 241 are fixedly mounted on the fixed base 21. The positioning light source receiving module 241 is used to receive the emitted light from the positioning light source emitting module 240.

[0173] The positioning light-shielding plate 242 is used to move synchronously with the optical path deflection element 26. Specifically, the positioning light-shielding plate 242 is fixed to the movable carrier 22, so that the positioning light-shielding plate 242 can move synchronously with the movable carrier 22 and the optical path deflection element 26. Furthermore, the positioning light-shielding plate 242 is movably located on one side of the positioning light source emitting module 240, so that the positioning light-shielding plate 242 can at least partially block the emitted light of the positioning light source emitting module 240. In addition, the positioning light-shielding plate 242 is designed to be approximately triangular in shape, tapering along a direction parallel to the central axis CA.

[0174] like Figure 25 As shown, the positioning light source emitting module 240 and the positioning light source receiving module 241 are positioned on opposite sides of the moving path of the positioning light-shielding plate 242. When the driving module 20 drives the movable carrier 22 to move along the central axis CA, the positioning light-shielding plate 242 and the optical path deflection element 26 move synchronously with the movable carrier 22. Because the positioning light-shielding plate 242 is approximately triangular in design, the area of ​​the positioning light-shielding plate 242 that blocks the emitted light gradually changes along the central axis CA. Therefore, the light intensity of the emitted light received by the positioning light source receiving module 241 changes with the movement of the positioning light-shielding plate 242, and the positioning light source receiving module 241 outputs a corresponding positioning signal according to the received light intensity.

[0175] When the positioning light-shielding plate 242 moves synchronously with the optical path deflection element 26 and the movable carrier 22, it will have different shielding areas on the emitted light of the positioning light source emitting module 240. As a result, the positioning light source receiving module 241 will receive different light intensities and output corresponding voltages as corresponding positioning signals. The displacement of the positioning light-shielding plate 242 can be deduced from the voltage value of the corresponding positioning signal output by the positioning light source receiving module 241, and thus the displacement of the optical path deflection element 26 can be confirmed.

[0176] like Figure 25 As shown, the camera module 2 also includes a light shield 28, which extends from the top of the positioning light source emitting module 240 and the top of the positioning light source receiving module 241 toward the positioning light shield 242.

[0177] In this embodiment, as Figure 24 As shown, the positioning light-shielding plate 242 is designed to taper gradually along a direction parallel to the central axis CA, forming approximately an isosceles triangle. Therefore, when the positioning light-shielding plate 242 moves along a direction parallel to the central axis CA, the area of ​​the positioning light-shielding plate 242 that blocks the emitted light gradually changes along the central axis CA. However, this utility model does not... Figure 24 The present embodiment of the positioning light-shielding plate 242 is limited to the present embodiment, but it may also adopt other forms such as Figures 14 to 22 Other implementation examples are shown. For descriptions of related structural and functional features, please refer to the aforementioned corresponding examples. Figures 14 to 22 The content of that paragraph will not be repeated here.

[0178] In this embodiment, as Figure 24 As shown, the optical path deflection element 26 is a single prism, but this invention is not limited to this. For example, please refer to... Figure 27 Its illustration Figure 24 A schematic diagram of another embodiment of the optical path switching element. Figure 27 In the embodiment, the optical path deflection element 26a consists of two prisms 260a, and these two prisms 260a can be bonded together, for example, with optical adhesive. As another example, please refer to... Figure 28 Its illustration Figure 26 A schematic diagram of another embodiment of the optical path switching element. Figure 28 In the embodiment, the optical path reversing element 26b includes two mirrors 260b, and the optical path reversing element 26b has two reflecting surfaces 261b and 263b.

[0179] The camera module 2 in this embodiment may further include a first light-shielding slot and a second light-shielding slot, respectively used to accommodate the positioning light source emitting module 240 and the positioning light source receiving module 241. Its structural configuration can be referred to, for example, as shown in the following example. Figure 10 For a description of the relevant structural and functional features, please refer to the aforementioned corresponding descriptions. Figure 10 The content of that paragraph will not be repeated here.

[0180] The positioning light source emitting module 240 of this embodiment may, for example, include multiple light source emitting units, and these light source emitting units may be arranged in an array. Alternatively, the positioning light source emitting module 240 may include a strip-shaped light source emitting unit, and the arrangement direction of the strip-shaped light source emitting unit may be perpendicular to the central axis CA. However, this utility model is not limited to the aforementioned embodiments.

[0181] The camera module 2 in this embodiment may further include a calibration module (not shown) to check whether there is an error in the displacement of the optical path reversing element 26 measured by the positioning module 24, and to correct it immediately if an error is confirmed. For example, the calibration module may include a calibration light source emitting module, a calibration light source receiving module, and a calibration light shield. The calibration light source emitting module and the calibration light source receiving module may both be fixedly mounted on a fixed base. The calibration light source receiving module is used to receive calibration light from the calibration light source emitting module.

[0182] A correction shield is used to move synchronously with the optical path reversing element. For example, the correction shield is fixed to a movable carrier, so that the correction shield can move synchronously with the movable carrier and the optical path reversing element. Furthermore, the correction shield is movably located on one side of the correction light source emitting module, so that the correction shield can block the correction light emitted by the correction light source emitting module. When the optical path reversing element moves to an origin position along the central axis, the correction shield blocks the correction light emitted by the correction light source emitting module, and the correction light source receiving module outputs a corresponding correction signal.

[0184] Please refer to Figures 29 to 31 ,in Figure 29 An exploded view of a camera module according to a third embodiment of the present invention is shown. Figure 30 Draw Figure 29 An enlarged schematic diagram of area A30, and Figure 31 Draw Figure 29 An enlarged schematic diagram of region A31.

[0185] In this embodiment, the camera module 3 is an optical image stabilization camera module, and the camera module 3 includes a drive module 30, a fixed base 31, a panning lens carrier 32, an imaging lens 33, a first positioning module 34, a second positioning module 35, a panning platform 36, and a lens bracket 37.

[0186] A movable platform 36 is mounted on a fixed base 31 and can be moved relative to the fixed base 31, and a movable lens carrier 32 is mounted on the movable platform 36 and can be moved relative to the movable platform 36. The direction of movement of the movable platform 36 is different from the direction of movement of the movable lens carrier 32, as described below.

[0187] The imaging lens 33 has a central axis CA. The imaging lens 33 is mounted on the lens support 37 and is set together with the lens support 37 on the movable lens carrier 32. In this way, the imaging lens 33 can move synchronously with the movable lens carrier 32.

[0188] The drive module 30 is used to drive the translational lens carrier 32 to move along a first direction D3 perpendicular to the central axis CA, and to drive the translational platform 36 to move along a second direction D4 perpendicular to the central axis CA, thereby synchronously driving the imaging lens 33 to move along the first direction D3 and / or the second direction D4. The first direction D3 is different from the second direction D4, and the first direction D3 is, for example, perpendicular to the second direction D4, but this invention is not limited thereto.

[0189] Specifically, the drive module 30 includes two first coils 300, two first magnets 301, four first rolling elements 302, two second coils 303, two second magnets 304, and four second rolling elements 305.

[0190] The first coil 300 and the first magnet 301 are correspondingly arranged, and one of the first coil 300 and the first magnet 301 can be fixed, for example, to the movable lens carrier 32 or the lens support 37. These first rolling elements 302 are respectively rotatably arranged in the four first guide grooves 360 of the movable platform 36, and these first rolling elements 302 support the movable lens carrier 32. These first guide grooves 360 extend along the first direction D3. The drive module 30 drives the movable lens carrier 32 to move by the electromagnetic driving force generated between the first coil 300 and the first magnet 301 after the first coil 300 is energized, and guides the movable lens carrier 32 together with the imaging lens 33 along the first direction D3 through the cooperation of the first rolling elements 302 and the first guide grooves 360. In this embodiment, these first rolling elements 302 are cylinders, but the present invention is not limited thereto.

[0191] The second coil 303 and the second magnet 304 are correspondingly arranged, and one of the second coil 303 and the second magnet 304 can be fixed, for example, to the movable lens carrier 32, the lens bracket 37, or the movable platform 36. These second rolling elements 305 are respectively rotatably disposed in the four second guide grooves 310 of the fixed base 31, and these second rolling elements 305 support the movable platform 36. These second guide grooves 310 extend along the second direction D4. The drive module 30 drives the movable platform 36 to move by the electromagnetic driving force generated between the second coil 303 and the second magnet 304 after the second coil 303 is energized, and guides the movable platform 36 together with the imaging lens 33 along the second direction D4 through the cooperation of the second rolling elements 305 and the second guide grooves 310. In this embodiment, these second rolling elements 305 are cylinders, but the present invention is not limited thereto.

[0192] The first positioning module 34 includes a first positioning light source emitting module 340, a first positioning light source receiving module 341, and a first positioning light shield 342. Both the first positioning light source emitting module 340 and the first positioning light source receiving module 341 are fixedly mounted on the movable platform 36. The first positioning light source receiving module 341 is used to receive the emitted light L1 from the first positioning light source emitting module 340.

[0193] The first positioning light-shielding plate 342 is used to move synchronously with the imaging lens 33. Specifically, the first positioning light-shielding plate 342 is fixed to the movable lens carrier 32, so that the first positioning light-shielding plate 342 can move synchronously with the movable lens carrier 32 and the imaging lens 33 in the first direction D3. Furthermore, the first positioning light-shielding plate 342 is movably located on one side of the first positioning light source emitting module 340, so that the first positioning light-shielding plate 342 can at least partially block the emitted light L1 of the first positioning light source emitting module 340. The first positioning light-shielding plate 342 is a rectangular progressive light-shielding plate, and the light transmittance of the first positioning light-shielding plate 342 gradually changes along the first direction D3.

[0194] The first positioning light source emitting module 340 and the first positioning light source receiving module 341 are located on the same side of the moving path of the first positioning light shield 342. The first positioning light shield 342 is used to reflect at least part of the emitted light L1 from the first positioning light source emitting module 340 to the first positioning light source receiving module 341, so as to achieve the function of at least partially blocking the emitted light L1. When the driving module 30 drives the translational lens carrier 32 to move along the first direction D3, the first positioning light shield 342 and the imaging lens 33 move synchronously with the translational lens carrier 32. Since the first positioning light shield 342 is a rectangular progressive light shield design, the light transmittance of the emitted light L1 through the first positioning light shield 342 will gradually change along the first direction D3, and the reflectivity of the first positioning light shield 342 for the emitted light L1 will also gradually change along the first direction D3. Therefore, the light intensity of the emitted light L1 received by the first positioning light source receiving module 341 will change as the first positioning light shield 342 moves, and the first positioning light source receiving module 341 will output a corresponding positioning signal according to the received light intensity.

[0195] When the first positioning light-shielding plate 342 moves synchronously with the imaging lens 33 and the panning lens carrier 32, it will have different reflectivities on the emitted light L1 of the first positioning light source emitting module 340. Thus, the first positioning light source receiving module 341 will receive different light intensities and output corresponding voltages as positioning signals. By analyzing the voltage value of the corresponding positioning signal output by the first positioning light source receiving module 341, the displacement of the first positioning light-shielding plate 342 in the first direction D3 can be deduced, and consequently, the displacement of the imaging lens 33 in the first direction D3 can be confirmed.

[0196] The second positioning module 35 includes a second positioning light source emitting module 350, a second positioning light source receiving module 351, and a second positioning light shield 352. Both the second positioning light source emitting module 350 and the second positioning light source receiving module 351 are fixedly mounted on the fixed base 31. The second positioning light source receiving module 351 is used to receive the emitted light L2 from the second positioning light source emitting module 350.

[0197] The second positioning light-shielding plate 352 is used to move synchronously with the imaging lens 33. Specifically, the second positioning light-shielding plate 352 is fixed to the translational platform 36, so that the second positioning light-shielding plate 352 can move synchronously with the translational platform 36 and the imaging lens 33 in the second direction D4. Furthermore, the second positioning light-shielding plate 352 is movably located on one side of the second positioning light source emitting module 350, so that the second positioning light-shielding plate 352 can at least partially block the emitted light L2 of the second positioning light source emitting module 350. The second positioning light-shielding plate 352 is also a rectangular progressive light-shielding plate, and the light transmittance of the second positioning light-shielding plate 352 gradually changes along the second direction D4.

[0198] The second positioning light source emitting module 350 and the second positioning light source receiving module 351 are located on the same side of the moving path of the second positioning light shield 352. The second positioning light shield 352 is used to reflect at least part of the emitted light L2 from the second positioning light source emitting module 350 to the second positioning light source receiving module 351, so as to achieve the function of at least partially blocking the emitted light L2. When the driving module 30 drives the translational platform 36 to move along the second direction D4, the second positioning light shield 352 and the imaging lens 33 move synchronously with the translational platform 36. Since the second positioning light shield 352 is a rectangular progressive light shield design, the light transmittance of the emitted light L2 through the second positioning light shield 352 will gradually change along the second direction D4, and the reflectivity of the emitted light L2 by the second positioning light shield 352 will also gradually change along the second direction D4. Therefore, the light intensity of the emitted light L2 received by the second positioning light source receiving module 351 will change as the second positioning light shield 352 moves, and the second positioning light source receiving module 351 will output a corresponding positioning signal according to the received light intensity.

[0199] When the second positioning light-shielding plate 352 moves synchronously with the imaging lens 33 and the translational platform 36, it will have different reflectivities on the emitted light L2 of the second positioning light source emitting module 350. Thus, the second positioning light source receiving module 351 will receive different light intensities and output corresponding voltages as positioning signals. By analyzing the voltage value of the corresponding positioning signal output by the second positioning light source receiving module 351, the displacement of the second positioning light-shielding plate 352 in the second direction D4 can be deduced, and consequently, the displacement of the imaging lens 33 in the second direction D4 can be confirmed.

[0200] The camera module 3 in this embodiment may further include a first light-shielding slot (not otherwise labeled) and a second light-shielding slot (not otherwise labeled). The first light-shielding slot is located on the movable platform 36 and is used to accommodate the first positioning light source emitting module 340 and the first positioning light source receiving module 341, so that the first positioning light source emitting module 340 and the first positioning light source receiving module 341 share the same light-shielding slot. In addition, the second light-shielding slot is located on the fixed base 31 and is used to accommodate the second positioning light source emitting module 350 and the second positioning light source receiving module 351, so that the second positioning light source emitting module 350 and the second positioning light source receiving module 351 share the same light-shielding slot.

[0201] The camera module 3 in this embodiment may further include a first light shield (not shown) and a second light shield (not shown), used to block ambient light from the first positioning module 34 and the second positioning module 35, respectively. For example, the first light shield may extend from the top of the first positioning light source emitting module and the top of the first positioning light source receiving module toward the first positioning light shield, and the first light shield is used to block ambient light from the first positioning module. Furthermore, the second light shield may extend from the top of the second positioning light source emitting module and the top of the second positioning light receiving module toward the second positioning light shield, and the second light shield is used to block ambient light from the second positioning module.

Alternatively, the first positioning light source emitting module 340 may include a strip-shaped light source emitting unit, and the arrangement direction of the strip-shaped light source emitting unit may be perpendicular to the central axis CA.

Alternatively, the second positioning light source emitting module 350 may include a strip-shaped light source emitting unit, and the arrangement direction of the strip-shaped light source emitting unit may be perpendicular to the central axis CA.
