Please refer to Figure 12, which is a schematic diagram of the cross-sectional structure of the camera module shown in Figure 3, wherein the camera is a front auxiliary camera. The camera 200 of the camera module 300 serves as a front auxiliary camera, the light deflection device 100 is in a deflected state, the first right-angle surface 221 of the prism 22 faces the first light hole, the second right-angle surface 222 faces the lens assembly 270 in the lens system 210, and the second right-angle surface 222 faces the third light hole.

The first drive member 31 faces the connection between the second plate 122 and the fourth plate 124 of the housing 12.

Please refer to FIG. 4, FIG. 5, FIG. 11 and FIG. 12, the working principle of the light deflection device 100 is as follows: in the initial state of the light deflection device 100, the conductive plate 322 is energized to make the coil 321 charged, and the current passes through the coil 321, and the coil 321 generates a magnetic field, and the polarity of the magnetic field of the coil 321 is the same as the polarity of the second magnet 312 of the first driving member 31. At this time, the magnetic field of the coil 321 generates a repulsive force on the second magnet 312 of the first driving member 31, driving the first driving member 31 to rotate, thereby driving the carrier 21 to rotate around the two connecting axes. 41 rotates, thereby driving the prism 22 in the carrier 21 to rotate; in this process, according to the characteristics of the magnetic field distribution of the coil 321, the magnetic force of the magnetic field of the coil 321 on the second magnet 312 is large, and when the first driving member 30 rotates until the first magnet 311 enters the magnetic field of the coil 321, the magnetic force of the magnetic field of the coil 321 on the second magnet 312 is greater than the magnetic force on the first magnet 311, thereby pushing the first driving member 31 to rotate to 90 degrees, so that the two limit blocks 13 slide from the first end 2191 of the two limit grooves 219 to the second end 2192. When the carrier 21 rotates to 90 degrees, the two limit blocks 13 slide to the second end 2192 of the two limit grooves 219 respectively, and the carrier 21 cannot continue to rotate, and the positioning state is maintained by the magnetic field effect of the magnetic field of the coil 321 and the magnetic field of the first driving member 31. At this time, the first right-angled surface 221 of the prism 22 faces the first light hole, the second right-angled surface 222 faces the third light hole, the reflecting surface 223 faces the first light hole and the third light hole, and the light deflection device 100 is in a deflected state. In this embodiment, the carrier 21 rotates around the optical axis of the first light hole and the second light hole, and the line connecting the centers of the two limit grooves 219 is perpendicular to the rotation direction of the carrier 21. It should be noted that in order to keep the light deflection device 100 in a deflected state, it is necessary to continue to pass current through the coil 321, so that the magnetic field force on the first driving member 31 and the gravity on the first driving member 31 are balanced, ensuring that the carrier 21 will not move due to the shaking of the electronic device 1000.

The direction of the current in the coil 321 is changed, and the polarity of the magnetic field of the coil 321 is opposite to the polarity of the first magnet 311 of the first driving member 31. The coil 321 generates an attractive force on the first magnet 311, driving the first driving member 31 to rotate, thereby driving the carrier 21 to rotate around the two connecting shafts 41, so that the two limit blocks 13 slide from the second ends 2192 of the two limit grooves 219 to the first ends 2191, thereby driving the prism 22 in the carrier 21 to rotate; in this process, according to the characteristics of the magnetic field distribution of the coil 321, the magnetic force of the magnetic field of the coil 321 on the first magnet 311 is large, and when the first driving member 30 rotates until the second magnet 312 enters the magnetic field of the coil 321, the magnetic force of the magnetic field of the coil 321 on the first magnet 311 is greater than the magnetic force on the second magnet 312, thereby pushing the first driving member 31 to rotate to 90 degrees, so that the two limit blocks 13 slide from the second ends 2192 of the two limit grooves 219 to the first ends 2191, respectively. The carrier 21 rotates to 90°, and the two limit blocks 13 slide to the first ends 2191 of the two limit grooves 219 respectively. The carrier 21 cannot continue to rotate, and the positioning state is maintained by the magnetic field of the coil 321 and the magnetic field effect of the first driving member 31. At this time, the first right-angle surface 221 of the prism 22 faces the third light hole, the second right-angle surface 222 faces the second light hole, and the reflecting surface faces the second light hole and the third light hole. The light deflection device 100 returns to the initial state. The coil 321 is continuously passed with current, and the magnetic field force on the first driving member 31 is balanced with the gravity on the first driving member 31, so that the light deflection device 100 is maintained in the initial state.

It should be noted that, in this embodiment, the electronic device 1000 is further provided with a Hall sensor, which can detect the rotation angle of the carrier 21 and send the rotation angle to the processor. The processor is used to control the carrier 21 to remain stationary or rotate according to the rotation angle. When the processor determines that the rotation angle of the carrier 21 is greater than or less than 90°, the processor controls the power module to change the current in the coil 321, controls the size of the magnetic field of the coil 321, and makes the first driving member 31 fine-tuned under the magnetic field force of the coil 321, so that the rotation angle of the carrier 21 is 90° (a certain tolerance can be allowed).

It can be understood that by providing two limit blocks 13 in the protective shell 10 of the light deflecting device 100 and providing two limit grooves 219 on the carrier 21, the two limit blocks 13 are respectively slidably connected to the two limit grooves 219, and when the carrier 21 rotates under the drive of the first driving member 31, the two limit blocks 13 can slide along the two limit grooves 219 respectively. Both limit grooves 219 are arc-shaped, and the angle of the arc is 90°. The two limit grooves 219 can be rotated 90° relative to the two limit blocks 13, respectively. Therefore, the two limit blocks 13 respectively limit the rotation angle of the two limit grooves 219, thereby limiting the rotation angle of the carrier 21, and preventing the rotation angle of the carrier 21 from being too large.

In addition, by setting up a Hall sensor, the processor can fine-tune the rotation angle of the carrier 21 by adjusting the current size according to the rotation angle of the carrier 21 detected by the Hall sensor, so that the rotation angle of the carrier 21 is exactly 90°. Without setting up an additional fine-tuning structure and without occupying additional internal space of the electronic device 1000, the rotation accuracy of the carrier 21 is improved, thereby ensuring the quality of the camera.

Please refer to FIG. 1 , FIG. 2 , FIG. 11 and FIG. 12 . In this embodiment, the camera module 300 is installed in the housing 500 so that the first light hole is opposite to the first light hole 510 and the second light hole is opposite to the second light hole 520. The working principle of the camera module 300 is as follows: the electronic device 1000 is in the first use state, that is, the camera 200 of the camera module 300 is a rear camera. At this time, the light deflection device 100 is in the initial state. The light reflected by the object enters the camera module 300 through the second light hole 520 and the second light hole. The light passes through the filter 240 and enters the prism 22 from the second right angle surface 222 of the prism 22. After being reflected by the reflection surface 223 of the prism 22, it is emitted from the first right angle surface 221 and enters the lens assembly 270 of the camera 200. That is, the light deflection device 100 deflects the light incident from the back plate 530 side of the electronic device 1000 to the camera 200. The camera 200 forms image data according to the light, and sends the image data to the processor for processing, and the display screen 600 displays the image according to the image data. Therefore, the electronic device 1000 is in the first use state, that is, the camera 200 of the camera module 300 is a rear camera, and the camera module 300 can obtain the image data of the object located on the back plate 530 side of the electronic device 1000, that is, the camera module 300 can take the image of the object behind the electronic device 1000 (on the back plate side of the electronic device 1000). Since the filter 240 covers the second light hole of the protective shell 10, the filter 240 can filter out infrared light to avoid image color distortion.

The electronic device 1000 is in the second use state, that is, the camera 200 of the camera module 300 is a front auxiliary camera. At this time, the light deflection device 100 is in the deflection state, and the light reflected by the object enters the camera module 300 through the first light hole 510 and the first light hole, and the light enters the prism 22 through the first right-angle surface 221 of the prism 22, and is reflected by the reflection surface 223 of the prism 22 and then emitted from the second right-angle surface 222 to enter the camera 200, that is, the light deflection device 100 deflects the light incident from the first light hole 510 to the camera 200. Therefore, when the electronic device 1000 is in the second use state, the camera module 300 can obtain the image data of the object in front of the electronic device 1000 (on the side of the display screen 600 of the electronic device 1000). Since the filter 240 is not provided at the first light hole, the camera 200 can obtain the infrared light image data of the object. The front camera can obtain visible light image data of the object in front of the electronic device 1000 (on the side of the display screen 600 of the electronic device 1000), and combined with the infrared light image data obtained by the camera module 300, the processor can process the visible light image data obtained by the front camera and the infrared light image data obtained by the camera module 300, and use them for face unlocking.

It can be understood that by combining the visible light image data and infrared light image data of the face, the accuracy of face unlocking can be improved, especially in dark environments, such as at night, when the error of the visible light image data of the face is large, the purpose of face unlocking can be achieved by using infrared light image data.

In this embodiment, the electronic device 1000 is further provided with an acceleration sensor, a light sensor and a gyroscope. The acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can be used to identify whether the electronic device 1000 is picked up. The light sensor can detect the visible light intensity of the environment in which the electronic device 1000 is located. The gyroscope can be used to detect the angle between the display screen 600 of the electronic device 1000 and the face of the person. The acceleration sensor and the light sensor are both connected to the processor, and the processor activates the front camera, the light deflection device 100 and the camera 200 by recognizing the signals of the acceleration sensor and the light sensor.

Please refer to Figures 13 and 14. Figure 13 is a schematic diagram of the control method for face recognition of the electronic device shown in Figure 1; Figure 14 is a logical diagram of the control method for face recognition of the electronic device shown in Figure 13. In this embodiment, the electronic device 1000 is in the second use state, and the camera module 300 combined with the front camera can be used for face unlocking. This embodiment provides a first embodiment of the control method for face unlocking of the electronic device 1000, and the control method includes the following steps:

Step 110: Determine whether the electronic device 1000 has a displacement, and determine whether the displacement matches a screen unlocking threshold;

Step 120: When it is determined that the displacement of the electronic device 1000 matches the screen unlocking threshold, the light deflection device is adjusted to transform the camera 200 from a rear camera to a front auxiliary camera;

Specifically, in this step, the electronic device 1000 is in the first use state by default, and the displacement of the electronic device 1000 includes spatial displacement and angular displacement. The acceleration sensor detects the acceleration of the electronic device 1000 (including the magnitude and direction of the acceleration) and transmits the acceleration to the processor. The gyroscope detects the angle between the display screen 600 of the electronic device 1000 and the face, and transmits the angle value to the processor. For example, the acceleration detected by the acceleration sensor is much greater than 0, and the direction of the acceleration detected by the acceleration sensor is toward the front of the electronic device 1000; the display screen 600 of the electronic device 1000 detected by the gyroscope is nearly parallel to the face, so that the display screen 600 can recognize the face.

In this step, when the processor determines that the displacement of the electronic device 1000 reaches the screen unlocking threshold, the processor controls the light deflection device 100 to switch the electronic device 1000 from the first usage state to the second usage state, the light deflection device 100 switches from the initial state to the deflection state, and the camera 200 of the camera module 300 is changed from a rear camera to a front auxiliary camera.

Step 130: The front camera obtains visible light image data of the face, and the camera 200 obtains infrared light image data of the face.

extracting feature data of a human face according to the visible light image data and the infrared light image data;

Specifically, in this step, the processor processes the visible light image data and the infrared light image data to extract the face

Feature data.

Step 140: Perform the face recognition based on the matching result of the feature data and the pre-stored data to obtain the face recognition result.

Specifically, in this step, the processor compares the feature data of the face with the pre-stored data in the database to determine whether the feature data of the face matches the pre-stored data.

When the processor determines that the feature data of the face matches the pre-stored data, the processor controls the display screen 600 to automatically unlock, and controls the electronic device 1000 to switch from the second use state to the first use state, that is, the camera 200 of the camera module 300 switches from the front auxiliary camera to the rear camera, and the light deflection device 100 switches from the deflection state to the initial state;

When the processor determines that the facial feature data does not match the pre-stored data, and the number of matches does not exceed three times, the user double-clicks the display screen 600 to continue face unlocking, and the front camera and the camera module 300 continue to obtain the visible light image data and infrared light image data of the object, respectively, and the processor continues to generate facial feature data based on the visible light image data and infrared light image data, and matches the facial feature data with the pre-stored data again. When the facial feature data does not match the pre-stored data, and the number of matches exceeds three times, the processor controls the display screen 600 to prompt the user to use a password to unlock.

When the processor determines that the display screen 600 is unlocked, or the processor determines that the display screen 600 is still not unlocked after a preset time, the processor controls the electronic device 1000 to switch from the second usage state to the first usage state, the light deflection device 100 switches from the deflection state to the initial state, and the camera 200 of the camera module 300 switches from the front auxiliary camera to the rear camera.

It can be understood that in this embodiment, when the electronic device 1000 is in the first use state, the camera 200 of the camera module 300 is a rear camera, and the camera module 300 can be used to take pictures; when the electronic device 1000 is in the second use state, the camera 200 of the camera module 300 is a front auxiliary camera, and the front auxiliary camera assists the front camera to realize face recognition. Therefore, the utilization rate of the camera module 300 is improved, and there is no need to set up an additional auxiliary camera to cooperate with the front camera to realize face recognition, thereby reducing the cost of the electronic device 1000, and it is also conducive to the miniaturization of the electronic device 1000.

In this embodiment, the electronic device 1000 further includes an extraction module, a judgment module and an execution module. The extraction module is used to extract the feature data of the face according to the visible light image data and the infrared light image data. The judgment module is used to judge whether the feature data matches the pre-stored data in the face database; the execution module is used to perform the unlocking operation.

In this embodiment, the carrier 61 includes a first support body 611, a second support body 612 and a connector 613.

The surfaces of the first support body 611 and the second support body 612 facing each other are respectively the first mating surfaces, and the cavity wall of the protective shell 50 includes the second mating surface, so that when the carrier 61 is installed in the protective shell 50, it can be matched with the structure of the protective shell 50. When the carrier 61 rotates in the cavity of the protective shell 50, the first mating surface slides along the second mating surface.

The carrier 61 includes a receiving cavity 6111, a receiving groove 617, a rotation groove 618 and a limiting groove 619. The connector 613 connects the first support body 611 and the second support body 612 to form the receiving cavity 6111. The receiving cavity 6111 is connected to the first notch 614 and the second notch 615. The first surface 6131 of the connector 613 faces the receiving cavity 6111.

The rotation groove 618 is a circular through groove. The rotation groove 618 is located in the middle of the second surface 6132 of the connector 613 and passes through the second surface 6132 and the first surface 6131 of the connector 613. The rotation groove 618 is in communication with the accommodating cavity 6111.

The length dimension of the second limiting groove 6192 is greater than the length dimension of the first limiting groove 6191. It can be understood that the trajectory of the first limiting groove 6191 and the trajectory of the second limiting groove 6192 are connected to form the same circle, that is, the centers of the arc-shaped first limiting groove 6191 and the second limiting groove 6192 coincide with each other, thereby ensuring the smooth rotation of the carrier 61 and the accuracy of the angle, and the first limiting groove 6191 and the second limiting groove 6192 are not connected to form a complete arc, which can save the volume of the carrier 61.

In this embodiment, the number of the connecting member 80 is one. The connecting member 80 includes a connecting shaft 81 and two shaft sleeves 82. The connecting shaft 81 is a cylindrical shaft body, and the two shaft sleeves 82 are respectively sleeved at opposite ends of the connecting shaft 81 and connected to the connecting shaft 81.

In this embodiment, the protective shell 50 and the carrier 61 are connected by the connecting member 80, and the carrier 61 is rotatably connected to the protective shell 50 through the connecting member 80. Specifically, the carrier 61 is rotatably connected to the bracket 51. The opposite ends of the connecting shaft 81 of the connecting member 80 are respectively located in the rotation hole 518 of the bracket 51 and the rotation groove 618 of the carrier 61 opposite thereto.

Specifically, the end of the base 260 provided with the first light-transmitting hole 261 is connected to the end of the protective shell 50 provided with the third light hole, and the first light-transmitting hole 261 of the base 260 is opposite to and connected to the third light hole of the protective shell 50. The third light hole is located on the light incident side of the camera 200. The first light-transmitting hole 261 is sealed and connected to the housing 52. The optical axis of the lens assembly 270 passes through the first light-transmitting hole 261 and the third light hole. The filter 240 is located in the accommodating space of the housing 12, and is located between the fifth wall 515 of the bracket 51 and the second plate 522 of the housing 52. The filter 240 is parallel to the optical axis of the lens assembly 270. The filter 240 covers the second light hole of the protective shell 50. The reflective surface 623 of the prism 62 and the filter 240 are located on the optical path of the camera 200. The filter 240 is located on the optical axis of the second optical hole, and the filter 240 is located on the side of the protective shell 10 where the second optical hole is provided.

The camera 200 of the camera module 300 is used as a rear camera, and the electronic device 1000 is in the first use state; the light deflection device 100 is in the initial state, and the limit block 53 of the bracket 51 is located in the first limit groove 6191 of the carrier 61, and is located at the end of the first limit groove 6191. The first right-angle surface 621 of the prism 62 faces the lens assembly 270 of the lens system 210, the first right-angle surface 621 faces the third light hole, the second right-angle surface 622 of the prism 62 faces the second light hole, and the reflective surface 623 faces the second light hole and the third light hole. The first driving member 71 and the second driving member 72 are spaced and opposite to each other.

Please refer to Figure 24, which is a schematic diagram of the cross-sectional structure of the camera module shown in Figure 15, wherein the camera is a front auxiliary camera. In this embodiment, the camera 200 of the camera module 300 is used as a front auxiliary camera, and the electronic device 1000 is in the second use state; the light deflection device 100 is in a deflected state. The limit block 53 of the bracket 51 is located in the second limit groove 6192 of the carrier 61, and is located at the end of the second limit groove 6192. The first right-angle surface 621 of the prism 62 faces the lens assembly 270 of the lens system 210, the first right-angle surface 621 faces the third light hole, and the second right-angle surface 622 faces the first light hole. The first driving member 71 and the second driving member 72 are spaced apart and opposite to each other.

Please continue to refer to FIG. 15, FIG. 16 and FIG. 23, FIG. 24. The working principle of the light deflection device 100 is as follows: in the initial state of the light deflection device 100, the magnetic force center of the magnetic field of the coil 721 is offset from the magnetic force center of the first magnet 711 and the second magnet 712 of the first driving member 71, and the multiple first magnets 711 and the multiple second magnets 712 of the first driving member 71 are arranged at intervals, and the polarity of the magnetic field of the coil 721 changes according to the magnetism of the magnets at different positions of the first driving member 71. When the conductive plate 722 is energized, the coil 721 is charged, and an alternating current passes through the coil 721, and the coil 721 generates a magnetic field. The magnetic field of the coil 721 causes the first driving member 71 to generate a torque under the action of the magnetic field force, which drives the first magnet 711 and the second magnet 712 in the magnetic field of the first driving member 71 to rotate. The multiple coils 721 are energized at the same time, so that the first driving member 71 rotates around the connecting shaft 81. Specifically, taking one of the second magnets 712 as an example, when the second magnet 712 is opposite to one of the coils 721 and is located in the magnetic field of the coil 721, the polarity of the coil 721 is opposite to that of the second magnet 712, and the coil 721 generates an attractive force on the second magnet 712, causing the second magnet 712 to rotate toward the coil 721; under the action of inertia, the second magnet 712 passes over the coil 721; at this time, the direction of the current is changed so that the polarity of the coil 721 is the same as that of the second magnet 712, and the coil 721 continues to provide a repulsive force on the second magnet 712, causing the second magnet 712 to rotate away from the coil 721; at the same time, the second magnet 712 approaches another coil 721 adjacent to the coil 721. The polarity of the other adjacent coil 721 is opposite to that of the second magnet 712, and generates an attractive force on the second magnet 712, causing the second magnet 712 to rotate toward the other adjacent coil 721. Under the action of inertia, the second magnet 712 passes over another adjacent coil 721, and the polarity of another adjacent coil 721 is the same as that of the second magnet 712. Another adjacent coil 721 provides repulsion to the second magnet 712, so that the second magnet 712 rotates away from another adjacent coil 721. By analogy, the direction of the current in the four coils 721 is constantly changing, so that the second magnet 712 rotates 180°; the first magnet 711 can also rotate 180°. By passing an alternating current through the coil 721, the first driving member 71 can be rotated, thereby driving the carrier 61 to rotate around the connecting shaft 81, so that the limit block 53 slides from the end of the first limit groove 6191 to the end of the second limit groove 6192. The carrier 61 rotates 180°, and the limit block 53 slides to the end of the second limit groove 6192. The carrier 61 cannot continue to rotate, and the magnetic field of the coil 721 and the magnetic field effect of the first driving member 71 maintain the positioning state. At this time, the first right-angled surface 621 of the prism 62 is still facing the third light hole, the second right-angled surface 622 is facing the first light hole, the reflecting surface 623 is facing the first light hole and the third light hole, and the light deflection device 100 is in a deflected state. It should be noted that in order to keep the light deflection device 100 in a deflected state, it is necessary to continue to pass current through the coil 721, so that the magnetic field force on the first driving member 71 and the gravity of the first driving member 71 are balanced, ensuring that the carrier 61 will not move due to the shaking of the electronic device 1000.

The conductive plate 722 is continuously energized to pass an alternating current through the coil 721, and the polarity of the magnetic field of the coil 721 changes according to the magnetism of the magnets at different positions of the first driving member 71. The magnetic field of the coil 721 causes the first driving member 71 to generate torque under the action of the magnetic field force, which drives the first magnet 711 and the second magnet 712 located in the magnetic field of the first driving member 71 to rotate. Multiple coils 721 are energized at the same time, causing the first driving member 71 to rotate around the connecting shaft 81, causing the limit block 53 to slide from the end of the second limit groove 6192 to the end of the first limit groove 6191. The carrier 61 rotates 180°, and the limit block 53 slides to the end of the first limit groove 6191. The carrier 61 cannot continue to rotate, and the magnetic field of the coil 721 and the magnetic field effect of the first driving member 71 keep the carrier 61 in a positioned state. At this time, the first right-angled surface 621 of the prism 62 faces the third light hole, the second right-angled surface 622 faces the second light hole, the reflecting surface 623 faces the second light hole and the third light hole, and the light deflection device 100 is back to the initial state. The current is continuously passed through the coil 721, and the magnetic field force on the first driving member 31 and the gravity on the first driving member 31 reach a balance, so that the light deflection device 100 is maintained in the initial state, ensuring that the carrier 61 will not move due to the shaking of the electronic device 1000.

It should be noted that, in this embodiment, the electronic device 1000 is further provided with a Hall sensor, which can detect the rotation angle of the carrier 61 and send the rotation angle to the processor. The processor is used to control the carrier 61 to remain stationary or rotate according to the rotation angle. When the processor determines that the rotation angle of the carrier 61 is greater than or less than 90°, the processor controls the power module to change the current in the coil 721, controls the size of the magnetic field of the coil 721, and makes the first driving member 71 fine-tuned under the magnetic field force of the coil 721, so that the rotation angle of the carrier 61 is 180° (a certain tolerance can be allowed).

It can be understood that by setting a limit block 53 in the protective shell 50 of the light deflecting device 100 and setting a limit groove 619 on the carrier 61, the limit block 53 is slidably connected to the limit groove 619, and the limit groove 619 includes a first limit groove 6191 and a second limit groove 6192, and the centers of the first limit groove 6191 and the second limit groove 6192 coincide. When the carrier 61 rotates under the drive of the first driving member 71, the limit block 53 can slide along the limit groove 619, and can slide from the end of the first limit groove 6191 to the end of the second limit groove 6192. Therefore, the limit block 53 limits the rotation angle of the limit groove 619, and then limits the rotation angle of the carrier 61, so as to prevent the rotation angle of the carrier 61 from being too large.

In addition, by setting up a Hall sensor, the processor can fine-tune the rotation angle of the carrier 61 by adjusting the current size according to the rotation angle of the carrier 61 detected by the Hall sensor, so that the rotation angle of the carrier 61 is exactly 90°. Without setting up an additional fine-tuning structure and without occupying additional internal space of the electronic device 1000, the rotation accuracy of the carrier 61 is improved, thereby ensuring the quality of the camera.

Please refer to FIG. 1, FIG. 2 and FIG. 23, FIG. 24. In this embodiment, the camera module 300 is installed in the housing 500 so that the first light hole is opposite to the first light hole 510, and the second light hole is opposite to the second light hole 520. The working principle of the camera module 300 is as follows: the electronic device 1000 is in the first use state, that is, the camera 200 of the camera module 300 is a rear camera. At this time, the light deflection device 100 is in the initial state, and the light reflected by the object enters the camera module 300 from the second light hole 520 and the second light hole. The light passes through the filter 240 and enters the prism 62 from the second right angle surface 622 of the prism 62, and is reflected by the reflection surface 623 of the prism 62 and then emitted from the first right angle surface 621 to enter the lens assembly 270 of the camera 200. That is, the light deflection device 100 deflects the light incident from the rear of the electronic device 1000 (that is, the back plate 530 side of the electronic device 1000) to the camera 200. The camera 200 forms image data according to the light, and sends the image data to the processor for processing, and the display screen 600 displays the image according to the image data. Therefore, the electronic device 1000 is in the first use state, that is, the camera 200 of the camera module 300 is a rear camera, and the camera module 300 can obtain the image data of the object located on the back plate 530 side of the electronic device 1000, that is, the camera module 300 can take the image of the object behind the electronic device 1000 (on the back plate side of the electronic device 1000). Since the filter 240 covers the second light hole of the protective shell 50, the filter 240 can filter out infrared light to avoid image color distortion.

The electronic device 1000 is in the second use state, that is, the camera 200 of the camera module 300 is a front auxiliary camera. At this time, the light deflection device 100 is in a deflection state, and the light reflected by the object enters the camera module 300 through the first light hole 510 and the first light hole. The light enters the prism 62 through the second right-angle surface 622 of the prism 22, and is reflected by the reflection surface 623 of the prism 62 and then emitted from the first right-angle surface 621 to enter the camera 200. That is, the light deflection device 100 deflects the light incident from the first light hole 510 to the camera 200. Therefore, when the electronic device 1000 is in the second use state, the camera module 300 can obtain the image data of the object in front of the electronic device 1000 (on the display screen side of the electronic device 1000). Since the filter 240 is not provided at the first light hole, the camera 200 can obtain the infrared light image data of the object. The front camera can obtain visible light image data of the object in front of the electronic device 1000 (on the side of the display screen 600 of the electronic device 1000), and combined with the infrared light image data obtained by the camera module 300, the processor can process the visible light image data obtained by the front camera and the infrared light image data obtained by the camera module 300, and use them for face unlocking.

By combining visible light image data and infrared light image data of a face, the accuracy of face unlocking can be improved, especially in a dark environment, such as at night, when the visible light image data of a face has a large error, the infrared image data can be used to achieve the purpose of face unlocking. In addition, in a dark environment, the feature data of the face can be obtained without lighting the display screen 600 of the electronic device 1000 to illuminate the face, which can improve the speed of face unlocking.

In this embodiment, the electronic device 1000 is further provided with an acceleration sensor and a light sensor. The acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes) and can be used to identify whether the electronic device 1000 is suddenly picked up. The light sensor can detect the visible light intensity of the environment in which the electronic device 1000 is located. The acceleration sensor and the light sensor are both connected to the processor, and the processor activates the light deflection device 100 and the camera 200 by identifying the signals of the acceleration sensor and the light sensor.

In this embodiment, the camera module 300 can be combined with the front camera for face unlocking. This embodiment provides a second embodiment of the control method for face unlocking of the electronic device 1000. The second embodiment of the control method for face unlocking of the electronic device 1000 is the same as the first embodiment of the control method for face unlocking of the electronic device 1000, and will not be repeated here.

It can be understood that in this embodiment, the camera 200 of the camera module 300 is a rear camera, which can be used for taking pictures; the camera 200 of the camera module 300 is a front auxiliary camera, which can be used in conjunction with the front camera to achieve face unlocking, avoiding the need to additionally set up an auxiliary camera to cooperate with the front camera to achieve face unlocking, thereby reducing the cost of the electronic device 1000, and is also conducive to the miniaturization of the electronic device 1000.

In this embodiment, the electronic device 1000 further includes an extraction module, a judgment module and an execution module. The extraction module is used to extract the feature data of the face according to the visible light image data and the infrared light image data. The judgment module is used to judge whether the feature data matches the pre-stored data in the face database; the execution module is used to perform the unlocking operation.

The difference between the camera module 300 provided in the third embodiment of the present application and the camera module 300 provided in the first embodiment is that the filter 240 is located inside the base 260, specifically between the sensor 220 and the circuit board 230.

In this embodiment, the structure of the light deflection device 100 is the same as that of the light deflection device 100 of the camera module 300 of the first embodiment, and will not be repeated here.

In this embodiment, the structure of the camera 200 is the same as the structure of the camera 200 of the camera module 300 of the first embodiment, and will not be repeated here.

Please refer to Figures 26 and 27 in combination. Figure 26 is a schematic diagram of the cross-sectional structure of the third embodiment of the camera module shown in Figure 25, wherein the camera is a rear camera; Figure 27 is a schematic diagram of the cross-sectional structure of the third embodiment of the camera module shown in Figure 25, wherein the camera is a front auxiliary camera. In this embodiment, the light deflection device 100 and the camera 200 are connected to form a camera module 300. Specifically, the end of the base 260 provided with the first light-transmitting hole 261 is connected to the end of the protective shell 10 provided with the third light hole, and the first light-transmitting hole 261 of the base 260 is opposite to and connected to the third light hole of the protective shell 10. The optical axis of the lens assembly 270 passes through the first light-transmitting hole 261 and the third light hole. The filter 240 is located between the sensor 220 and the circuit board 230, and the filter 240 is perpendicular to the optical axis of the lens assembly 270. The filter 240 and the third light hole are both located on the optical axis of the lens assembly 270.

The camera 200 of the camera module 300 is a rear camera, the electronic device 1000 is in the first use state, the light deflection device 100 is in the initial state, the first right-angle surface 221 of the prism 22 faces the lens assembly 270 in the lens system 210, the second right-angle surface 222 faces the second light hole, and the reflective surface 623 faces the second light hole and the third light hole. The camera 200 of the camera module 300 is a front auxiliary camera, the electronic device 1000 is in the second use state, the light deflection device 100 is in the deflection state, the first right-angle surface 221 of the prism 22 faces the first light hole, the second right-angle surface 222 faces the lens assembly 270 in the lens system 210, and the reflective surface 223 faces the first light hole and the third light hole.

In this embodiment, the camera module 300 is installed in the housing 500 so that the first light hole is opposite to the first light hole 510, and the second light hole is opposite to the second light hole 520. The working principle of the camera module 300 is as follows: the electronic device 1000 is in the first use state, the light deflection device 100 is in the initial state, and the camera 200 of the camera module 300 is a rear camera. The light reflected by the object enters the prism 22 from the second light hole 520 through the second right angle surface 222 of the prism 22, and is reflected by the reflection surface 223 of the prism 22. Then, it is emitted from the first right angle surface 221 and enters the camera 200, and passes through the lens assembly 270 and the filter 240 in the camera 200 to reach the sensor 220. The camera 200 forms image data according to the light, and sends the image data to the processor for processing, and the display screen 600 displays the image according to the image data. At this time, the camera module 300 can capture the image of the object behind the electronic device 1000 (on the back panel side of the electronic device 1000). Since the filter 240 is located between the sensor 220 and the lens assembly 270 , the filter 240 can filter out infrared light to avoid image color distortion.

When the electronic device 1000 is in the second use state, the light deflection device 100 is in the deflection state, and the camera 200 of the camera module 300 is a front auxiliary camera. The light reflected by the object enters the prism 22 from the first light hole 510 through the first right-angle surface 221 of the prism 22, and is reflected by the reflection surface 223 of the prism 22 and then emitted from the second right-angle surface 222 to enter the camera 200, and successively passes through the lens assembly 270 and the filter 240 in the camera 200 to reach the sensor 220. Since the lens assembly 270 is a periscope lens, the camera 200 can obtain the image data of the object at a distance located in front of the electronic device 1000 (on the display screen 600 side of the electronic device 1000). Since the filter 240 is located between the sensor 220 and the lens assembly 270, the filter 240 can filter out infrared light to avoid image color distortion. At this time, the camera module 300 can obtain the visible light image data of the object in front of the electronic device 1000 (on the display screen side of the electronic device 1000). The front camera can obtain visible light image data of the object in front of the electronic device 1000 (on the side of the display screen 600 of the electronic device 1000). Combined with the visible light image data obtained by the camera module 300, the processor can process the visible light image data obtained by the front camera and the visible light image data obtained by the camera module 300, and send the processed image data to the display screen 600 for display, thereby realizing depth photography and blurring the background of the object.

In this embodiment, the electronic device 1000 is further provided with a capacitive sensor, which can sense and respond to touch signals. The capacitive sensor is connected to the processor. When the capacitance value of the capacitive sensor changes by touching the display screen 600, the processor can determine the touch position and touch state according to the capacitive sensor, thereby starting the front camera, the light deflection device 100 and the camera 200.

Please continue to refer to Figures 28 and 29. Figure 28 is a schematic diagram of the control method for the electronic device shown in Figure 1 for depth photography; Figure 29 is a logical diagram of the control method for the electronic device shown in Figure 1 for depth photography. In this embodiment, the electronic device 1000 is in the second state, and the camera module 300 can be combined with the front camera for depth photography. This embodiment provides a first embodiment of the control method for the electronic device 1000 for depth photography, and the control method includes the following steps:

Step 210: Determine whether the front camera is clicked and whether the large aperture mode is selected;

Specifically, in this step, the processor detects the capacitance value of the capacitive sensor at the position corresponding to the front camera button on the display screen 600 of the electronic device 1000, and determines whether the front camera of the electronic device 1000 is clicked to turn on according to the capacitance value. The processor detects the capacitance value of the capacitive sensor at the position corresponding to the large aperture mode button on the display screen 600, and determines whether the large aperture mode of the electronic device 1000 is selected according to the capacitance value.

Step 220: when it is determined that the front camera is activated and the large aperture mode is selected, the light deflection device 100 is adjusted to switch the camera 200 from a rear camera to a front auxiliary camera;

Specifically, in this step, when the processor determines that the front camera of the electronic device 1000 is clicked to turn on and the large aperture mode is selected, the processor controls the light deflection device 100 of the camera module 300 to switch the electronic device 1000 from the first usage state to the second usage state, that is, the camera 200 of the camera module 300 is changed from a rear camera to a front camera, and the light deflection device 100 is switched from the initial state to the deflection state.

Step 230: the front camera acquires visible light image data of the object, the camera module 300 acquires visible light image data of the object, and transmits the visible light image data of the front camera and the visible light image data of the camera module 300 to the processor respectively, the processor forms processed data, and sends the processed data to the display screen 600 for display;

Specifically, in this step, the processor processes the visible light image data respectively acquired by the front camera and the camera module 300 , blurs the background according to the depth, forms processed data, and sends the processed data to the display screen 600 for display.

Step 240: Determine whether the large aperture mode is cancelled. When it is determined that the large aperture mode is cancelled, adjust the light deflection device 100 to switch the electronic device 1000 from the second usage state to the first usage state, that is, the camera 200 of the camera module 300 is switched from the front camera to the rear camera.

Specifically, in this step, the processor detects the capacitance value of the capacitance sensor corresponding to the position of the large aperture mode button on the display screen 600 of the electronic device 1000, and determines whether the large aperture mode of the electronic device 1000 is cancelled according to the capacitance value. When the processor determines that the large aperture mode is cancelled, the processor controls the light deflection device 100 to switch the electronic device 1000 from the second use state to the first use state, and the camera 200 of the camera module 300 is switched from the front camera to the rear camera, and the camera module 300 can re-acquire the visible light image data of the object located on the back panel 530 side of the electronic device 1000.

It can be understood that in this embodiment, when the electronic device 1000 is in the first use state, the camera 200 of the camera module 300 is a rear camera, and the camera module 300 can be used to take pictures; when the electronic device 1000 is in the second use state, the camera 200 of the camera module 300 is a front auxiliary camera, and the camera module 300 can achieve depth photography in combination with the front camera. Therefore, the utilization rate of the camera module 300 is improved, and there is no need to set up an additional auxiliary camera to cooperate with the front camera to achieve face unlocking, thereby reducing the cost of the electronic device 1000, and it is also conducive to the miniaturization of the electronic device 1000.

In this embodiment, the electronic device 1000 further includes a combination module, which is used to process the visible light image data of the front camera and the visible light image data of the front auxiliary camera to form processed data.

At this time, the camera module 300 can obtain visible light image data of the object in front of the electronic device 1000 (on the display screen side of the electronic device 1000). The front camera can obtain visible light image data of the object located in front of the electronic device 1000 (on the side of the display screen 600 of the electronic device 1000). Combined with the visible light image data obtained by the camera module 300, the processor can process the visible light image data obtained by the front camera and the visible light image data obtained by the camera module 300, and send the processed image data to the display screen 600 for display, thereby realizing depth photography and blurring the background of the object.

In this embodiment, the electronic device 1000 is also provided with a capacitive sensor, which can sense and respond to touch signals. The capacitive sensor is connected to the processor.
