Description

Method for determining telescopic state of camera shooting assembly, readable storage medium and related equipment

Technical Field

The embodiment of the application relates to the field of machinery, in particular to a method for determining the telescopic state of a camera shooting assembly and electronic equipment comprising the camera shooting assembly.

Background

Nowadays, as the screen occupation ratio of electronic devices (e.g., smart phones, tablet computers, netbooks, etc.) by consumers is higher and higher, it is a trend to realize comprehensive screens of electronic devices. The front camera becomes the biggest problem of preventing the real realization of a full screen.

In order to really realize a full-screen, a lifting type camera is adopted in the prior art. When a user needs to use the camera, the driving assembly controls the camera to pop up (as shown in 1A in figure 1), and when the camera is not used, the camera is folded up (as shown in 1B in figure 1), so that the camera does not occupy the screen space. In order to better control the lifting type camera, the electronic equipment needs to determine the telescopic state of the camera when the driving assembly works. Including whether to normally extend or retract, whether to successfully extend, whether to successfully retract, whether to block rotation, and the like.

The existing method is to determine the telescopic state of the camera by detecting the magnetic flux. However, when the magnetic environment is severe or is influenced by an external magnetic field, it is difficult to accurately determine the telescopic state of the camera. In addition, the calibration threshold of the magnetic field is difficult to determine due to instability of the magnetic environment. Further, a device for detecting magnetic flux needs to be provided in the electronic apparatus, which is costly.

Therefore, it is necessary to provide a method for determining the telescopic state of the camera, which has strong anti-interference capability, simple operation and high result reliability.

For example, when a photo is taken, the shutter is opened, light is transmitted to the photographic assembly photosensitive element through the lens, the optical signal is converted into an electric signal, and the photographic assembly photosensitive element transmits the electric signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in camera 493.

The camera 493 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the handset 100 may include 1 or N cameras 493, where N is a positive integer greater than 1.

The digital signal processor is used for processing digital signals, and can process digital image signals and other digital signals. For example, when the handset 100 is in frequency bin selection, the digital signal processor is used to perform fourier transform or the like on the frequency bin energy.

Video codecs are used to compress or decompress digital video. Handset 100 may support one or more video codecs. Thus, the handset 100 can play or record video in a variety of encoding formats, such as: moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, and the like.

The NPU is a neural-network (NN) computing processor that processes input information quickly by using a biological neural network structure, for example, by using a transfer mode between neurons of a human brain, and can also learn by itself continuously. The NPU can realize applications such as intelligent recognition of the mobile phone 100, for example: image recognition, face recognition, speech recognition, text understanding, and the like.

The external memory interface 420 may be used to connect an external memory card, such as a Micro SD card, to extend the storage capability of the mobile phone 100. The external memory card communicates with the processor 410 through the external memory interface 420 to implement data storage functions. For example, files such as music, video, etc. are saved in an external memory card.

The internal memory 421 may be used to store computer-executable program code, including instructions. The internal memory 421 may include a program storage area and a data storage area. The storage program area may store an operating system, an application program (such as a sound playing function, an image playing function, etc.) required by at least one function, and the like. The data storage area may store data (e.g., audio data, a phonebook, etc.) created during use of the handset 100, and the like. In addition, the internal memory 421 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), and the like. The processor 410 executes various functional applications of the cellular phone 100 and data processing by executing instructions stored in the internal memory 421 and/or instructions stored in a memory provided in the processor.

The handset 100 may implement audio functions through the audio module 470, the speaker 470A, the receiver 470B, the microphone 470C, the application processor, and the like. Such as music playing, recording, etc.

The audio module 470 is used to convert digital audio information into an analog audio signal output and also used to convert an analog audio input into a digital audio signal. The audio module 470 may also be used to encode and decode audio signals. In some embodiments, the audio module 470 may be disposed in the processor 410, or some functional modules of the audio module 470 may be disposed in the processor 410.

The speaker 470A, also called a "horn", is used to convert the audio electrical signals into sound signals. The handset 100 may play voice or notify etc. through the speaker 470A.

The receiver 470B, also called "earpiece", is used to convert the electrical audio signal into an acoustic signal. When the cellular phone 100 receives a call or voice information, it can receive voice by placing the receiver 470B close to the ear of the person.

The microphone 470C, also referred to as a "microphone," is used to convert sound signals into electrical signals. When making a call or transmitting voice information, the user can input a voice signal into the microphone 470C by speaking the user's mouth near the microphone 470C. The handset 100 may be provided with at least one microphone 470C. In other embodiments, the handset 100 may be provided with two microphones 470C to achieve noise reduction functions in addition to collecting sound signals. In other embodiments, the mobile phone 100 may further include three, four or more microphones 470C to collect sound signals, reduce noise, identify sound sources, and implement directional recording functions.

The pressure sensor is used for sensing a pressure signal and converting the pressure signal into an electric signal.

The gyro sensor can be used to determine the pose during movement of the handset 100.

The magnetic sensor includes a hall sensor. In some embodiments, physical parameters such as current, position, orientation, etc. may be measured by sensing magnetic field strength with a magnetic sensor.

The acceleration sensor can detect the magnitude of acceleration of the cellular phone 100 in various directions (typically three axes).

The fingerprint sensor is used for collecting fingerprints. Any type of sensing technology may be employed including, but not limited to, optical, capacitive, piezoelectric, or ultrasonic sensing technologies, etc. The mobile phone 100 can utilize the collected fingerprint characteristics to realize fingerprint unlocking, access application lock, fingerprint photographing and the like.

Touch sensors, also known as "touch devices". The touch sensor (also referred to as a touch panel) may be disposed on the display screen 494, and the touch sensor and the display screen 494 form a touch screen, also referred to as a "touch screen". The touch sensor is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine a touch event type. Visual output associated with the touch operation may be provided through the display screen 494. In other embodiments, the touch sensor can be disposed on a surface of the handset 100 at a different location than the display screen 494.

The keys 490 include a power-on key, a volume key, etc. The keys 490 may be mechanical keys. Or may be touch keys. The cellular phone 100 may receive a key input, and generate a key signal input related to user setting and function control of the cellular phone 100.

The motor 491 may generate a vibration indication. The motor 491 may be used for both incoming call vibration prompting and touch vibration feedback. For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 491 may also respond to different vibration feedback effects in response to touch operations applied to different areas of the display screen 494. Different application scenes (such as time reminding, receiving information, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

The indicator 492 may be an indicator light, and may be used to indicate a charging status, a change in charge level, or a message, a missed call, a notification, etc.

The SIM card interface 495 is used to connect a SIM card. The SIM card can be attached to and detached from the cellular phone 100 by being inserted into the SIM card interface 495 or being pulled out from the SIM card interface 495. The handset 100 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 495 may support a Nano SIM card, a Micro SIM card, a SIM card, etc. Multiple cards can be inserted into the same SIM card interface 495 at the same time. The types of the plurality of cards may be the same or different. The SIM card interface 495 may also be compatible with different types of SIM cards. The SIM card interface 495 may also be compatible with an external memory card. The mobile phone 100 interacts with the network through the SIM card to implement functions such as communication and data communication. In some embodiments, the handset 100 employs esims, namely: an embedded SIM card. The eSIM card can be embedded in the mobile phone 100 and cannot be separated from the mobile phone 100.

The basic principle of the method for determining the telescopic state of the camera shooting assembly in the embodiment of the application is as follows: the electronic equipment analyzes the environmental noise collected by the two MICs through the built-in environmental noise collected by the two MICs at different positions of the electronic equipment, and determines the telescopic state of the camera shooting assembly. The camera shooting assembly stretching state comprises whether the camera shooting assembly is successfully started to stretch, whether the camera shooting assembly is in a normal stretching state, whether the camera shooting assembly successfully stretches out, whether the camera shooting assembly successfully retracts, whether the camera shooting assembly is locked up or not and the like.

The method for determining the telescopic state of the camera module according to the embodiment of the present application is specifically described below with reference to the mobile phone in fig. 4. The methods in the following embodiments may be implemented in an electronic device having the above hardware structure or an electronic device having a similar structure.

The method for determining the telescopic state of the camera shooting assembly according to the embodiment of the application is described below by using the relative positions of the first MIC101, the second MIC102 and the camera shooting device 110 shown in fig. 2. Specifically, a first MIC101 is disposed at the bottom end of the mobile phone 100, and a second MIC102 is disposed near the camera assembly 103. As shown in fig. 5, the method may include S501-S503.

S501, in response to the first operation of the user, the mobile phone 100 starts the driving component 104.

Wherein the first operation may be a start-up operation for the camera. For example, the lock screen interface of the handset 100 includes an icon of the camera that the user clicks on in the first operation. As another example, the main interface of the cell phone 100 includes an icon of the camera, which the user clicks in the first operation. For another example, an application installed in the mobile phone 100 (e.g., pan, beauty camera, WeChat, etc.) may call the camera, and the first operation is the user initiating an operation to call the camera in the application (e.g., initiating a scan in pan, clicking a shot short video icon in WeChat, etc.).

In one possible implementation, the handset 100 may trigger the driving component 104 to start by sending an enable signal to the driving component 104. Specifically, after the driving assembly 104 receives the enabling signal, the driving assembly 104 drives the driving bracket 106 to drive the camera assembly bracket 105 to drive the camera assembly 103 to extend or retract.

In some embodiments, the handset 100 may also instruct the driving assembly 104 to drive the camera assembly 103 in the direction of motion by sending a direction signal to the driving assembly 104. For example, in fig. 2, the driving component 104 receives an upward direction signal, and the driving component 104 drives the image pickup component 103 to extend upward; if the direction signal is downward, the driving component 104 drives the camera component 103 to retract downward.

Fig. 6 is a schematic diagram of an operating circuit of a driving assembly according to an embodiment of the present disclosure. After receiving the enable signal and the clock signal sent by the CPU of the mobile phone 100, the driving component 104 sets the initial parameter to zero according to the initialization signal, and sets the clock register of the driving component 104 to zero. The drive assembly 104 then performs directional parameter setting based on the received directional signal. Then, the driving component 104 outputs a-phase current and B-phase current through the a-phase coil and the B-phase coil under the driving of the enable signal according to the set direction parameters. Under the action of the A-phase current and the B-phase current, the driving motor is driven towards the corresponding direction.

S502, in response to the start of the driving component 104, the cell phone 100 collects the first environmental noise N1 through the first MIC101 and collects the second environmental noise N2 through the second MIC102 during the operation of the driving component 104.

As described above, since the first MIC101 in fig. 2 is farther from the drive assembly 104, the second MIC102 is closer to the drive assembly 104. Thus, it can be understood that: of the second ambient noise collected by the second MIC102, the noise generated by the operation of the drive component 104 is larger than the first ambient noise collected by the first MIC 101. Among other things, the operation of the drive assembly 104 may include: the whole process that the driving component 104 drives the camera component 103 to extend, and the whole process that the driving component 104 drives the camera component 103 to retract. Therefore, the first environmental noise mainly includes the noise of the external environment. The second ambient noise mainly includes superposition of ambient noise and noise generated by operation of the drive assembly 104. Here, it can be considered that the noise of the external environment in the first environmental noise is the same as the noise of the external environment in the second environmental noise.

S503, the mobile phone 100 determines the expansion/contraction state of the camera module 103 according to the first environmental noise N1 and the second environmental noise N2.

The telescopic state of the camera assembly 103 includes, but is not limited to, any of the following: starting extension/starting retraction, normal extension/normal retraction, locked rotor, ending extension/ending retraction, abnormal retraction and abnormal power failure. The specific determination method of abnormal recovery and abnormal power failure will be described in detail below.

In one possible implementation, the mobile phone 100 may store the noise threshold corresponding to each of the above expansion states. The noise threshold may be understood as a value, for example, a locked-rotor noise threshold. The noise threshold can also be understood as a range. For example, the noise threshold corresponding to each scaling state may include { lower threshold corresponding to the scaling state, upper threshold corresponding to the scaling state }, where the lower threshold of each scaling state < the upper threshold of the scaling state. For example, the normal scaling noise threshold includes { lower limit of the normal scaling noise threshold, upper limit of the normal scaling noise threshold }. Wherein, the noise thresholds corresponding to different stretching states are different.

For example, based on a large amount of experimental data as shown in fig. 7, noise thresholds for different telescoping states may be determined and each noise threshold may be preconfigured in the handset 100. For example: starting noise threshold T_startIs 19 dB-25 dB, wherein 19 is the lower limit of the starting noise threshold, and 25dB is the upper limit of the starting noise threshold. Locked rotor noise threshold T_locked-rotorIs 31dB, normal scaling noise threshold T_working7 dB-12 dB, and the telescopic noise threshold T is finished_finishIs 15dB to 20 dB.

In some embodiments, the electronic device may not be pre-configured with noise thresholds for respectively initiating protraction/initiating retraction and ending protraction/ending retraction. That is, the states of start of extension/start of retraction and end of extension/end of retraction are not judged according to the noise threshold.

In a possible implementation manner, the electronic device may perform the expansion state judgment according to a preset waiting time. For example, the preset startup waiting time is 0.2s, and if the noise generated by the driving component 104 after the enable time passes 0.2s meets the normal protrusion noise threshold, the driving component 104 is considered to be successfully started. Fig. 7 is a schematic diagram of an operating noise of a driving assembly according to an embodiment of the present disclosure. As shown in fig. 7, at time 0s, the driving element 104 is activated, and the driving element 104 activation noise is 21dB, and after about 0.2s, the activation is completed. Then the driving assembly 104 works normally and the camera assembly 103 extends normally. At time 0.8s, the drive assembly 104 stalls and the noise suddenly rises to 33 dB. At time 0.9s, the drive assembly 104 retracts the camera assembly 103 and the noise falls back to 0 dB. At time 1.1s, the drive assembly 104 is restarted, with a start-up noise of 24dB, after which the camera assembly 103 is extended normally. At time 1.5s, the handset suddenly loses power. After rebooting, the drive assembly 104 again retracts the camera assembly 103 and, at time 1.7s, the drive assembly 104 is restarted again. Then, the image pickup assembly 103 normally extends out until the time 2.5s, and the driving assembly 104 collides with the frame of the accommodating cavity 111. At this point, the noise decibel is 18dB, ending the protrusion.

In one possible implementation, the determining, by the mobile phone 100, the expansion/contraction state of the camera assembly 103 according to the first environmental noise N1 and the second environmental noise N2 (i.e., S503), may include S5031 and S5032:

s5031, the mobile phone 100 obtains a difference N between the first environmental noise N1 and the second environmental noise N2.

The first environmental noise N1 collected by the first MIC101 is mainly noise of the external environment, and the second environmental noise N2 collected by the second MIC102 is superposition of the external environment and noise generated by the operation of the image pickup assembly 104. Therefore, the difference N between the first environmental noise N1 and the second environmental noise N2 reflects the noise generated when the image pickup unit 104 operates.

S5032, the mobile phone 100 compares the noise threshold corresponding to each expansion state with N, and determines the expansion state of the camera assembly 103.

In some embodiments, the handset 100 may also start as a machine when the handset 100 sends the enable signal and the direction signal to the drive assembly 104, recording the operating duration of the drive assembly 104. For example, the handset 100 records the operation duration of the driving component 104 by sending a Clock signal (Clock, CLK) to the driving component 104.

For example, as shown in fig. 8, at time t1, the mobile phone 100 drives the driving bracket 106 via the driving motor 107 to extend the camera assembly 103, and CLK starts timing.

In one possible implementation, the S5032, that is, the mobile phone 100 respectively compares N with the noise threshold corresponding to each expansion state to determine the expansion state of the camera assembly 103 (i.e., S5032), may include: if N satisfies the threshold T_startI.e. N is greater than the lower threshold T of the starting noise_start1And is less than the upper limit T of the starting noise threshold_start2The mobile phone 100 determines that the camera assembly 103 starts to extend; if N satisfies the locked-rotor noise threshold T_locked-rotorI.e. N is greater than the locked-rotor noise threshold T_locked-rotorThe mobile phone 100 determines that the camera assembly 103 is locked; if N satisfies the normal telescopic noise threshold T_workingI.e. N is greater than the lower threshold T of the normal telescopic noise_working1And is less than the upper limit T of the normal telescopic noise threshold_working2The mobile phone 100 determines that the camera assembly 103 is normally extended; if N satisfies the end stretch noise threshold T_finishI.e. N is greater than the lower threshold T for ending the stretch noise_finish1And is less than the upper limit T of the end telescopic noise threshold_finish2The cell phone 100 determines that the camera assembly 103 is finished zooming.

In some embodiments, if the environmental noise collected by the first MIC is greater than a predetermined threshold (e.g., 90dB), the mobile phone 100 may abandon the determination of the expansion state of the camera module according to the embodiment of the present application. Since the second MIC may have difficulty accurately detecting the operating noise of the drive assembly 104 when the environment is very noisy. Therefore, the method of the embodiment of the present application has poor effect. In this case, the cellular phone 100 may not make a judgment. The mobile phone 100 may also pop up a window on the display screen or alert the user with a voice, and the determination of the telescopic state of the camera assembly will be abandoned during the operation of the driving assembly 104. In one possible implementation, the mobile phone 100 can further determine whether the telescopic state of the camera assembly 103 is locked-rotor during extension or locked-rotor during retraction, whether extension or retraction is initiated, whether normal extension or normal retraction is initiated, or whether extension or retraction is terminated, in conjunction with the direction signal.

In another possible implementation manner, in S5032, the comparing N with the noise threshold corresponding to each expansion state by the cell phone 100 to determine the expansion state of the camera assembly 103 respectively may include:

if N satisfies the normal telescopic noise threshold T_workingI.e. N is greater than the lower threshold T of the normal telescopic noise_working1And is less than the upper limit T of the normal telescopic noise threshold_working2The mobile phone 100 determines that the camera assembly 103 is normally extended; and, if the image pickup module 103 expands and contracts for a time t_workingSatisfies the following conditions:

the expansion and contraction state of the image pickup module 103 is determined to be the end of expansion and contraction. Wherein l is the distance that the camera assembly 103 needs to move to extend or retract, v_workingThe speed at which the camera assembly 103 is normally extended or retracted, which may be pre-designed and configured in the handset 100.

For example, as shown in fig. 8, at time t1, the cellular phone 100 drives the driving mount 106 by the driving motor 107, and the first MIC101 and the second MIC102 start measuring noise. Where the first MIC101 and the second MIC102 measure the first environmental noise N1 to be 20dB and the second environmental noise N2 to be 42dB, respectively, it may be determined that the operating noise N-N2-N1-22 dB of the driving component 104 is shown as point a in fig. 8. Because N-22 dB meets the starting noise threshold T_start(e.g. T)_start19dB), the cellular phone 100 determines whether the telescopic state of the camera module 103 at time t1 is the start of extension or the start of retraction. Since the direction signal is upward, the telescopic state of the camera module 103 at time t1 can be further determined as the start of extension.

At time t3, N1 was measured as 20dB, N2 is 30dB, the operating noise of the drive assembly 104 can be determined to be 10dB, as shown at point C in fig. 8. Because N is 10dB and meets the normal telescopic noise threshold T_working(e.g. T)_working7dB), the cellular phone 100 determines that the telescopic state of the camera module 103 at time t3 is the normal telescopic state. Since the direction signal is upward, it can be further determined that the image pickup assembly 103 is in the extended state at time t 3.

At time t4, where N1 is measured as 20dB and N2 is measured as 53dB, the operating noise of the drive assembly 104 may be determined as 33dB, as indicated by point D in FIG. 8. Because N is 33dB, the locked-rotor noise threshold T is satisfied_locked-rotor(e.g. T)_locked-rotor31dB), the cellular phone 100 determines that the telescopic state of the camera module 103 at time t4 is locked rotation. Since the direction signal is upward, it can be further determined that the image pickup unit 103 is locked in rotation when the image pickup unit is extended at time t 4.

At time t5, where N1 is measured as 20dB and N2 is measured as 20dB, the operating noise of the drive assembly 104 may be determined as 0dB, as indicated by point E in FIG. 8. Since the last expansion state of the driving unit 104 is locked-rotor when extending, the mobile phone 100 determines that the expansion state of the camera unit 103 at time t5 is locked-rotor and then restarts the mobile phone.

At time t6, where N1 is measured as 20dB and N2 is measured as 44dB, the operating noise of the drive assembly 104 may be determined as 24dB, as indicated by point F in FIG. 8. Since the start noise threshold of 19dB is met by 24dB, the mobile phone 100 determines that the camera assembly 103 is in the extended state at time t6 as a restart extension.

At time t7, where N1 is measured to be 20dB and N2 is measured to be 32dB, the operating noise of the drive assembly 104 can be determined to be 12dB, as indicated at point G in FIG. 8. Since N-12 dB satisfies the normal telescopic noise threshold of 7dB, the cellular phone 100 determines that the telescopic state of the camera module 103 at time t7 is the normal extension.

At time t8, where N1 is measured as 20dB and N2 is measured as 20dB, the operating noise of the drive assembly 104 may be determined as 0dB, as indicated by point H in FIG. 8. Since the last expansion and contraction state of the driving assembly 104 was the normal extension, the cellular phone 100 determines that the expansion and contraction state of the camera assembly 103 at the time t8 is the power-down-in-extension state.

At time t9, where N1 is measured as 20dB and N2 is measured as 44dB, the operating noise of the drive assembly 104 may be determined as 24dB, as indicated by point I in FIG. 8. Since the start noise threshold of 19dB is met by 24dB, the mobile phone 100 determines that the camera assembly 103 is in the extended state at time t9 as a restart extension.

At time t10, where N1 is measured to be 20dB and N2 is measured to be 32dB, the operating noise of the drive assembly 104 may be determined to be 12dB, as shown at point J in FIG. 8. Since N is 12dB greater than the normal telescopic noise threshold by 7dB, the cellular phone 100 determines that the camera module 103 is in the telescopic state at time t10 as being in the normal extended state.

At time t11, where N1 is measured as 20dB and N2 is measured as 338dB, the operating noise of the drive assembly 104 may be determined as 18dB, as indicated by point K in FIG. 8. Since N is 18dB, the end stretch noise threshold T is satisfied_finish(e.g. T)_finish15dB), the cellular phone 100 determines that the telescopic state of the camera module 103 at time t11 is the end of extension.

In some embodiments, to determine where the camera assembly 103 is located. For example, the handset 100 may need to determine the location of the camera assembly 103 locked out from rotation, or before power is lost. Also for example, the handset 100 needs to know the telescopic position of the camera assembly 103. As shown in fig. 9, after 503, the method for determining the telescopic state of the camera assembly 103 according to the embodiment of the present application may further include:

s504, the mobile phone 100 determines the telescopic position information of the camera module 103 according to the telescopic information of the camera module 103.

Wherein, the telescopic information of the camera assembly 103 can be recorded by the mobile phone 100. The scaling information includes, but is not limited to, scaling state information and time information corresponding to each scaling state.

As shown in fig. 8, at time t4, the cellular phone 100 determines that the telescopic state of the camera module 103 is the lock-up in extension. The mobile phone 100 can determine the specific position of the locked rotor according to the time information recorded by the CLK and the information of the expansion state of the driving component 104. Specifically, at time t1, the camera assembly 103 is activated to extend. At time t3, the camera module 103 is activated and extended normally. At time t4, the camera assembly 103 stalls while extended.

In one possible implementation, × v may be calculated according to the formula (t4-t3)_workingThe distance the camera assembly 103 has been extended at time t4 is calculated. Wherein v is_workingThe normal extension or retraction speed of the camera assembly 103, which may be pre-designed and configured in the handset 100.

For example, v_workingAt 8mm/s, the camera assembly 103 starts to extend at 0.3s and stalls at 0.7 s. It can be determined that the camera assembly 103 stalls when it extends 3.2 mm.

In another possible implementation manner, the extending or retracting speed of the camera assembly 103 may also be changed in real time, and the mobile phone 100 may obtain the real-time extending and retracting speed of the camera assembly 103 through a sensor or the like. In this possible implementation, the method can be implemented according to

The distance the camera assembly 103 has been extended at time t4 is calculated. Wherein v is_iIs t_iReal-time stretch-and-shrink speed, Δ t, measured at a time_iHolding v for the camera assembly 103_iThe duration of the speed scaling.

For example, the camera assembly 103 is extended at a speed of 6mm/s starting at 0.3 s. At 0.4s, the ramp-up was extended at 7 mm/s. At 0.5s, the protrusion was started at 8 mm/s. Until stalling at 0.7 s. It was determined that l ═ (0.4s-0.3s) × mm/s + (0.5s-0.4s) × 7mm/s + (0.7s-0.5s) × 8mm/s was 2.9 mm. I.e., the camera assembly 103 stalls when it extends 2.9 mm.

In some embodiments, if the driving component 104 is not currently activated or does not drive the camera component 103, and at least the following conditions are satisfied, the mobile phone 100 determines that the driving component 104 is powered down, or the mobile phone 100 is powered down:

the latest enabling time of the camera assembly 103 for telescopic information recording is less than t_working。

In some embodiments, the first MIC101 and the second MIC102 may continue to collect ambient noise after the drive assembly 104 is powered down.

In some embodiments, if the driving element 104 receives the enable signal, and the difference N between the first environmental noise and the second environmental noise is greater than T_stopThe handset 100 determines the driverThe last retraction of the movable member 104 was a press retraction. Wherein, T_stopIs a noise threshold at which the drive assembly 104 is not activated. E.g. T_stopMay include { T }_stop1，T_stop2In which T is_stop1For an unactuated noise threshold lower bound, T_stop2For an unactuated upper noise threshold, T_stop1＜T_stop2。

Since the drive assembly 104 does not receive the enable signal, it indicates that the drive motor (107, 107-1 or 107-2) is not operating. The noise N at this time is mechanical noise caused by an external force. The lower noise threshold limit for proper operation of the drive assembly 104 is not exceeded.
