The processor is adapted to control the carrier 21 to remain stationary or to rotate in dependence on the angle of rotation. 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, and controls the magnitude of the magnetic field of the coil 321, so that the first driving member 31 is finely tuned under the action of the magnetic force of the coil 321, and the rotation angle of the carrier 21 is 90 ° (a certain tolerance may be allowed).

It can be understood that by providing two limiting blocks 13 in the protective housing 10 of the light deflection device 100 and providing two limiting grooves 219 on the carrier 21, the two limiting blocks 13 are slidably connected to the two limiting grooves 219, and when the carrier 21 rotates under the driving of the first driving member 31, the two limiting blocks 13 can slide along the two limiting grooves 219. The two limiting grooves 219 are arc-shaped, the arc-shaped angle is 90 degrees, and the two limiting grooves 219 can rotate 90 degrees relative to the two limiting blocks 13 respectively, so that the two limiting blocks 13 limit the rotation angle of the two limiting grooves 219 respectively, further limit the rotation angle of the carrier 21, and the excessive rotation angle of the carrier 21 is avoided.

In addition, through setting up hall sensor, the rotation angle of carrier 21 that the processor can detect according to hall sensor, can finely tune carrier 21's rotation angle through the adjustment electric current size, makes carrier 21's rotation angle just be 90, under the not extra inner space that sets up fine setting structure and does not occupy electronic equipment 1000 in addition, improves carrier 21's rotation precision, has guaranteed the quality of making a video recording.

Referring to fig. 1, fig. 2, fig. 11 and fig. 12, in the present embodiment, the camera module 300 is installed in the housing 500, such 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: when the electronic device 1000 is in the first use state, that is, the camera 200 of the camera module 300 is a rear camera, the light beam deflection device 100 is in an initial state, the light beam reflected by the object enters the camera module 300 through the second light passing hole 520 and the second light passing hole, the light beam enters the prism 22 through the optical filter 240 from the second right angle surface 222 of the prism 22, and exits from the first right angle surface 221 into the lens assembly 270 of the camera 200 after being reflected by the reflecting surface 223 of the prism 22, that is, the light beam deflection device 100 deflects the light beam 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 rays, and sends the image data to the processor for processing, and the display screen 600 displays an image according to the image data. Therefore, in the first use state of the electronic device 1000, that is, the camera 200 of the camera module 300 is a rear camera, the camera module 300 may acquire image data of a subject located on the back plate 530 side of the electronic device 1000, that is, the camera module 300 may capture an image of a subject behind the electronic device 1000 (on the back plate side of the electronic device 1000). Since the optical filter 240 covers the second light hole of the protective housing 10, the optical filter 240 can filter out infrared light, thereby avoiding color distortion of the image.

In the second use state of the electronic device 1000, that is, the camera 200 of the camera module 300 is a front auxiliary camera, at this time, the light beam deflection device 100 is in a deflected state, the light beam reflected by the object enters the camera module 300 through the first light hole 510 and the first light hole, the light beam enters the prism 22 through the first right angle surface 221 of the prism 22, and exits from the second right angle surface 222 to enter the camera 200 after being reflected by the reflecting surface 223 of the prism 22, that is, the light beam deflection device 100 deflects the light beam incident from the first light hole 510 to the camera 200. Therefore, in the second use state of the electronic apparatus 1000, the camera module 300 can acquire image data of a subject in front of the electronic apparatus 1000 (on the display screen 600 side of the electronic apparatus 1000). Since the optical filter 240 is not disposed at the first pupil, the camera 200 can acquire infrared light image data of the subject. The front camera can acquire visible light image data of a shot object in front of the electronic device 1000 (on the display screen 600 side of the electronic device 1000), and the processor can process the visible light image data acquired by the front camera and the infrared light image data acquired by the camera module 300 in combination with the infrared light image data acquired by the camera module 300 and is used for face unlocking.

It can be understood that by combining the visible light image data and the infrared light image data of the face, the accuracy of face unlocking can be improved, and especially in an environment with darker light, for example, at night, when the error of the visible light image data of the face is larger, the purpose of face unlocking can be achieved by utilizing the infrared light image data.

In this embodiment, the electronic device 1000 is further provided with an acceleration sensor, a light sensor and a gyroscope, where the acceleration sensor can detect the acceleration in all directions (typically three axes), and can be used to identify whether the electronic device 1000 is lifted. The light sensor may detect the intensity of visible light in the environment in which the electronic device 1000 is located. The gyroscope may be used to detect the angle of the display 600 of the electronic device 1000 with the face. The acceleration sensor and the light sensor are both connected to a processor, which activates the front camera, the light deflection device 100 and the camera 200 by recognizing signals from the acceleration sensor and the light sensor.

Referring to fig. 13 and 14, fig. 13 is a schematic diagram of a control method for face recognition by the electronic device shown in fig. 1; fig. 14 is a logic diagram of a control method for face recognition by the electronic device shown in fig. 13. In this embodiment, when the electronic device 1000 is in the second use state, the combination of the camera module 300 and the front camera may be used for face unlocking. The present embodiment provides a first embodiment of a control method for face unlocking of an electronic device 1000, where the control method includes the following steps:

step 110: judging whether the electronic equipment 1000 generates displacement or not, and judging whether the displacement is matched with a screen unlocking threshold value or not;

step 120: when the displacement of the electronic equipment 1000 is judged to be matched with the screen unlocking threshold, the light deflection device is adjusted, so that the camera 200 is changed into a front auxiliary camera from a rear 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 a spatial displacement and an angular displacement. The acceleration sensor detects the acceleration (including the magnitude and direction of the acceleration) of the electronic device 1000 and transmits the acceleration to the processor. The gyroscope detects the angle of the display 600 of the electronic device 1000 with the face and transmits the angle value to the processor. For example, the acceleration detected by the acceleration sensor is much larger than 0, and the direction of the acceleration detected by the acceleration sensor is toward the front of the electronic apparatus 1000; the display 600 of the electronic device 1000 detected by the gyroscope is approximately parallel to the face, so that the display 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 use state to the second use state, the light deflection device 100 switches from the initial state to the deflected state, and the camera 200 of the camera module 300 is changed from the rear camera to the front auxiliary camera.

Step 130: the front camera acquires visible light image data of a human face, and the camera 200 acquires infrared light image data of the human face

According to the data, extracting characteristic 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

And (5) characteristic data.

Step 140: and carrying out the face recognition based on the matching result of the characteristic 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 judges that the characteristic data of the face is matched with the pre-stored data, the processor controls the display screen 600 to be automatically unlocked, and controls the electronic equipment 1000 to be switched from the second use state to the first use state, namely the camera 200 of the camera module 300 is switched from the front auxiliary camera to the rear camera, and the light deflection device 100 is switched from the deflection state to the initial state;

When the processor judges that the feature data of the face is not matched with the pre-stored data and the matching times are not more than three times, the user double-clicks the display screen 600 to unlock the face continuously, the front camera and the camera module 300 respectively continue to acquire the visible light image data and the infrared light image data of the shot object, the processor continuously generates the feature data of the face according to the visible light image data and the infrared light image data, and the feature data of the face is matched with the pre-stored data again. When the feature data of the face is not matched with the pre-stored data and the matching times are more than three times, the processor controls the display screen 600 to prompt the user to unlock by using the password.

When the processor determines that the display screen 600 is unlocked, or the processor determines that the preset time period is exceeded, the display screen 600 is not yet unlocked, the processor controls the electronic device 1000 to switch from the second use state to the first use 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 appreciated that in the present 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 for photographing; 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 the face recognition is realized without additionally arranging an auxiliary camera to be matched with the front camera, so that the cost of the electronic equipment 1000 is reduced, and the miniaturization of the electronic equipment 1000 is facilitated.

In this embodiment, the electronic device 1000 further includes an extracting module, a judging module, and an executing module. The extraction module is used for extracting the characteristic data of the human face according to the visible light image data and the infrared light image data. The judging module is used for judging whether the characteristic data are matched with prestored data in the face database or not; the execution module is used for executing unlocking operation.

In this embodiment, the light deflecting device 100 and the camera 200 are connected to form a camera module 300. Specifically, the end portion of the base 260 provided with the first light hole 261 is butted with the end portion of the protective housing 50 provided with the third light hole, and the first light hole 261 of the base 260 is opposite to and communicated with the third light hole of the protective housing 50. The third light aperture is located on the light entrance side of the camera 200. The first light hole 261 is hermetically connected with the housing 52. The optical axis of the lens assembly 270 passes through the first light hole 261 and the third light hole. The filter 240 is located in the receiving space of the housing 12 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 optical filter 240 covers the second light hole of the protective case 50. The reflecting surface 623 of the prism 62 and the filter 240 are located in the optical path of the camera 200. The optical filter 240 is located on the optical axis of the second light hole, and the optical filter 240 is located on the side of the protection shell 10 provided with the second light hole.

The camera 200 of the camera module 300 is used as a rear camera, and the electronic device 1000 is in a first use state; the light deflection device 100 is in an initial state, and the limiting block 53 of the bracket 51 is located in the first limiting groove 6191 of the carrier 61 and is located at an end of the first limiting 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 aperture, the second right angle surface 622 of the prism 62 faces the second aperture, and the reflective surface 623 faces the second aperture and the third aperture. The first driving member 71 and the second driving member 72 are spaced apart from each other.

Referring to fig. 24 in combination, fig. 24 is a schematic cross-sectional structure of the camera module shown in fig. 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 limiting block 53 of the bracket 51 is located in the second limiting groove 6192 of the carrier 61, and is located at the end of the second limiting 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 aperture, and the second right angle surface 622 faces the first aperture. The first driving member 71 and the second driving member 72 are spaced apart from each other.

With continued reference to fig. 15, 16, 23 and 24, the light deflection device 100 operates according to the following principles: in the light deflection device 100, in the initial state, the magnetic centers of the magnetic fields of the coils 721 are offset from the magnetic centers of the first magnet 711 and the second magnet 712 of the first driving member 71, the plurality of first magnets 711 and the plurality of second magnets 712 of the first driving member 71 are disposed at intervals, and the polarity of the magnetic fields of the coils 721 is changed corresponding to the magnetic polarities of the magnets at different positions of the first driving member 71. The conductive plate 722 is energized to energize the coil 721, the coil 721 generates a magnetic field by an alternating current, the magnetic field of the coil 721 causes the first driving member 71 to generate torque by the magnetic field force, and the first magnet 711 and the second magnet 712 located in the magnetic field of the first driving member 71 are driven to rotate, and the plurality of coils 721 are energized simultaneously to rotate the first driving member 71 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 the polarity of the second magnet 712, and the coil 721 generates suction force to the second magnet 712, so that the second magnet 712 rotates toward the coil 721; under inertial action, the second magnet 712 passes over the coil 721; at this time, the current direction 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 repulsive force to the second magnet 712, so that the second magnet 712 rotates away from the coil 721; meanwhile, the second magnet 712 approaches the other coil 721 adjacent to the coil 721. The adjacent other coil 721 has a polarity opposite to that of the second magnet 712, and generates a suction force to the second magnet 712, causing the second magnet 712 to rotate toward the adjacent other coil 721. Under the inertia action, the second magnet 712 passes over the adjacent other coil 721, the polarity of the adjacent other coil 721 is the same as that of the second magnet 712, and the adjacent other coil 721 provides repulsive force to the second magnet 712, so that the second magnet 712 rotates away from the adjacent other coil 721. By analogy, the direction of current in the four coils 721 is constantly changing, rotating the second magnet 712 180 °; the first magnet 711 can also be rotated 180 °. By passing an alternating current through the coil 721, the first driving member 71 is rotated, thereby driving the carrier 61 to rotate about the connection shaft 81, and the stopper 53 is slid from the end of the first stopper groove 6191 to the end of the second stopper groove 6192. The carrier 61 rotates 180 °, the stopper 53 slides to the end of the second stopper groove 6192, the carrier 61 cannot continue to rotate, and the positioning state is maintained by the magnetic field of the coil 721 and the magnetic field effect of the first driver 71. At this time, the first right angle surface 621 of the prism 62 is still directed to the third light hole, the second right angle surface 622 is directed to the first light hole, the reflection surface 623 is directed to the first light hole and the third light hole, and the light deflecting device 100 is in a deflected state. In order to keep the light beam deflection apparatus 100 in the deflected state, it is necessary to continuously apply a current to the coil 721, and the magnetic field force applied to the first driver 71 and the gravity of the first driver 71 are balanced, so that the carrier 61 is ensured not to move due to the shaking of the electronic device 1000.

Continuing to energize the conductive plate 722 causes alternating current to pass through the coil 721, and causes the polarity of the magnetic field of the coil 721 to change corresponding 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, so that the first magnetic body 711 and the second magnetic body 712 located in the magnetic field of the first driving member 71 are driven to rotate, and the plurality of coils 721 simultaneously energize to rotate the first driving member 71 around the connecting shaft 81, so that the limiting block 53 slides from the end of the second limiting groove 6192 to the end of the first limiting groove 6191. The carrier 61 rotates 180 °, the stopper 53 slides to the end of the first stopper groove 6191, the carrier 61 cannot continue to rotate, and the positioning state is maintained by the magnetic field of the coil 721 and the magnetic field effect of the first driver 71. At this time, the first right angle surface 621 of the prism 62 faces the third aperture, the second right angle surface 622 faces the second aperture, and the reflection surface 623 faces the second aperture and the third aperture, and the light deflecting device 100 is again in the initial state. The current is continuously supplied to the coil 721, so that the magnetic force received by the first driving member 31 and the gravity received by the first driving member 31 are balanced, the light deflection device 100 is maintained in the initial state, and the carrier 61 is ensured not to move due to the shaking of the electronic device 1000.

In this embodiment, a hall sensor is further provided in the electronic device 1000, and the hall sensor can detect the rotation angle of the carrier 61 and send the rotation angle to the processor. The processor is configured to control the carrier 61 to remain stationary or rotate in accordance with the angle of rotation. 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, and controls the magnitude of the magnetic field of the coil 721, so that the first driving member 71 is finely tuned under the force of the magnetic field of the coil 721, and the rotation angle of the carrier 61 is 180 ° (a certain tolerance may be allowed).

It can be appreciated that by providing the stopper 53 in the protective housing 50 of the light deflection device 100 and providing the stopper slot 619 on the carrier 61, the stopper 53 is slidably connected to the stopper slot 619, the stopper slot 619 includes a first stopper slot 6191 and a second stopper slot 6192, and the centers of the circles of the first stopper slot 6191 and the second stopper slot 6192 coincide. When the carrier 61 rotates under the driving of the first driving member 71, the limiting block 53 can slide along the limiting slot 619 and can slide from the end of the first limiting slot 6191 to the end of the second limiting slot 6192. Thus, the limiting block 53 limits the rotation angle of the limiting slot 619, thereby limiting the rotation angle of the carrier 61, and avoiding the excessive rotation angle of the carrier 61.

In addition, through setting up hall sensor, the rotation angle of carrier 61 that the processor can detect according to hall sensor's rotation angle, can finely tune carrier 61's rotation angle through the adjustment electric current size, makes carrier 61's rotation angle just be 90, under the not extra inner space that sets up fine setting structure and does not occupy electronic equipment 1000 in addition, improves carrier 61's rotation precision, has guaranteed the quality of making a video recording.

Referring to fig. 1, fig. 2, fig. 23, and fig. 24, in the present embodiment, the camera module 300 is installed in the housing 500, such 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: when the electronic device 1000 is in the first use state, i.e. the camera 200 of the camera module 300 is a rear camera, the light beam deflection device 100 is in an initial state, the light beam reflected by the object enters the camera module 300 from the second light passing hole 520 and the second light passing through the optical filter 240, enters the prism 62 from the second right angle surface 622 of the prism 62, and exits from the first right angle surface 621 into the lens assembly 270 of the camera 200 after being reflected by the reflecting surface 623 of the prism 62, i.e. the light beam deflection device 100 deflects the light beam incident from the rear of the electronic device 1000 (i.e. the back plate 530 side of the electronic device 1000) to the camera 200. The camera 200 forms image data according to the light rays, and starts the image data to the processor for processing, and the display screen 600 displays an image according to the image data. Therefore, in the first use state of the electronic device 1000, that is, the camera 200 of the camera module 300 is a rear camera, the camera module 300 may acquire image data of a subject located on the back plate 530 side of the electronic device 1000, that is, the camera module 300 may capture an image of a subject behind the electronic device 1000 (on the back plate side of the electronic device 1000). Since the optical filter 240 covers the second light hole of the protective housing 50, the optical filter 240 can filter out infrared light, thereby avoiding color distortion of the image.

In the second use state of the electronic device 1000, that is, the camera 200 of the camera module 300 is a front auxiliary camera, at this time, the light beam deflection device 100 is in a deflected state, the light beam reflected by the object enters the camera module 300 through the first light hole 510 and the first light hole, the light beam enters the prism 62 through the second right angle surface 622 of the prism 22, and exits from the first right angle surface 621 to enter the camera 200 after being reflected by the reflecting surface 623 of the prism 62, that is, the light beam deflection device 100 deflects the light beam incident from the first light hole 510 to the camera 200. Therefore, in the second use state of the electronic apparatus 1000, the camera module 300 can acquire image data of a subject in front of the electronic apparatus 1000 (on the display screen side of the electronic apparatus 1000). Since the optical filter 240 is not disposed at the first pupil, the camera 200 can acquire infrared light image data of the subject. The front camera can acquire visible light image data of a shot object in front of the electronic device 1000 (on the display screen 600 side of the electronic device 1000), and the processor can process the visible light image data acquired by the front camera and the infrared light image data acquired by the camera module 300 in combination with the infrared light image data acquired by the camera module 300 and is used for face unlocking.

By combining the visible light image data and the infrared light image data of the human face, the accuracy of unlocking the human face can be improved, and especially when the error of the visible light image data of the human face is large in an environment with darker light, such as at night, the purpose of unlocking the human face can be achieved by utilizing the infrared image data. In addition, in an environment with darker light, the feature data of the face can be obtained without lighting the display screen 600 of the electronic device 1000 to illuminate the face, so that the speed of face unlocking can be increased.

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

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

It can be appreciated that in this embodiment, the camera 200 of the camera module 300 is a rear camera and can be used for photographing; the camera 200 of the camera module 300 is a front auxiliary camera, can be matched with the front auxiliary camera to realize face unlocking, and avoids the additional arrangement of the auxiliary camera to be matched with the front auxiliary camera to realize face unlocking, so that the cost of the electronic equipment 1000 is reduced, and the miniaturization of the electronic equipment 1000 is facilitated.

Referring to fig. 25, fig. 25 is a partially exploded view of a third embodiment of a camera module of the electronic device shown in fig. 1. The difference between the camera module 300 according to the third embodiment of the present application and the camera module 300 according to 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 the present 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 the detailed description thereof is omitted.

Referring to fig. 26 and 27 in combination, fig. 26 is a schematic cross-sectional structure of a third embodiment of the camera module shown in fig. 25, wherein the camera is a rear camera; fig. 27 is a schematic cross-sectional structure of a third embodiment of the camera module shown in fig. 25, where the camera is a front auxiliary camera. In this embodiment, the light deflecting device 100 and the camera 200 are connected to form a camera module 300. Specifically, the end portion of the base 260 provided with the first light hole 261 is butted with the end portion of the protective housing 10 provided with the third light hole, and the first light hole 261 of the base 260 is opposite to and communicated with the third light hole of the protective housing 10. The optical axis of the lens assembly 270 passes through the first light hole 261 and the third light hole.

The camera 200 forms image data according to the light rays, and starts the image data to the processor for processing, and the display screen 600 displays an image according to the image data. At this time, the camera module 300 can capture an image of a subject behind the electronic apparatus 1000 (on the back plate side of the electronic apparatus 1000). Because the filter 240 is located between the sensor 220 and the lens assembly 270, the filter 240 can filter out infrared light, avoiding image color distortion.

In the second use state of the electronic device 1000, the light beam deflection device 100 is in a deflected state, and the light beam reflected by the object of the camera 200 of the camera module 300 is reflected by the front auxiliary camera, enters the prism 22 from the first light passing hole 510 through the first right-angle surface 221 of the prism 22, exits from the second right-angle surface 222 to enter the camera 200 after being reflected by the reflecting surface 223 of the prism 22, and reaches the sensor 220 sequentially through the lens assembly 270 and the optical filter 240 in the camera 200. Since the lens assembly 270 is a periscope, the camera 200 can acquire image data of a subject located at a long distance in front of the electronic apparatus 1000 (on the display screen 600 side of the electronic apparatus 1000). Because the filter 240 is located between the sensor 220 and the lens assembly 270, the filter 240 can filter out infrared light, avoiding image color distortion. At this time, the camera module 300 can acquire visible light image data of a subject in front of the electronic apparatus 1000 (on the display screen side of the electronic apparatus 1000). The front camera can acquire visible light image data of a shot object in front of the electronic device 1000 (on the display screen 600 side of the electronic device 1000), and the processor can process the visible light image data acquired by the front camera and the visible light image data acquired by the camera module 300 in combination with the visible light image data acquired by the camera module 300 and send the processed image data to the display screen 600 for display, so that deep photographing is realized, and the background of the shot object is virtual.

In this embodiment, the electronic device 1000 is further provided with a capacitive sensor, and the capacitive sensor can realize sensing and response to a touch signal. The capacitive sensor is connected to a processor, and when the capacitance value of the capacitive sensor is changed by touching the display screen 600, the processor can determine a touch position and a touch state according to the capacitive sensor, thereby starting the front camera, the light deflecting device 100, and the camera 200.

With continued reference to fig. 28 and 29, fig. 28 is a schematic diagram illustrating a control method of the electronic device shown in fig. 1 for deep photographing; fig. 29 is a logic diagram of a control method for deep photographing of the electronic device shown in fig. 1.
