Before describing the technical solutions of the embodiments of the present application more clearly, some concepts in the present application are described in detail to better understand the present solution.
A terminal: the method refers to a smart device with a camera, a speaker, and other hardware (except for a display screen), and specifically may refer to the first terminal in the scene diagram shown in fig. 1.
The present application will be described in detail with reference to specific examples.
In the following embodiments, for convenience of description, only the main subject of execution of each step is described as a terminal.
Referring to fig. 2, a schematic flow chart of a camera control method according to an embodiment of the present disclosure is shown, where the method according to the embodiment of the present disclosure may include the following steps:
s201, when the camera collects images, obtaining the frequency value of the audio currently played by the terminal.
In some embodiments, when the camera captures an image, the terminal plays an audio at the same time, and the audio signal of the audio can be identified by the frequency identification model, so that the frequency value of the audio can be obtained. The frequency identification model can be obtained by adopting a neural network model for training in advance, and when the frequency identification model is trained, an audio signal covering a common audio frequency range can be collected to be used as a sample to train the frequency identification model, so that the frequency identification model can output the frequency value of the audio signal according to the input audio signal.
S202, if the frequency value of the audio is determined to be the same as the frequency value of the vibration frequency of the camera motor, the volume of the audio is obtained.
It is understood that the vibration frequency refers to the natural frequency of the camera motor, and the natural frequency refers to a specific frequency determined only by the properties of the system when the structural system is excited by the outside to generate motion. In the present embodiment, there may be multiple natural frequencies of the camera motor.
In some embodiments, the terminal may store a plurality of natural frequencies of the camera motor in advance, and may directly acquire the stored frequency value of the natural frequency when determining whether the frequency value of the played audio is the same as the frequency value of the natural frequency of the camera motor, and then determine whether the frequency value of the audio is the same as any one of the natural frequency values, and when any one of the natural frequency values is the same as the frequency value of the audio, may determine the frequency value of the audio and the frequency value of the natural frequency (vibration frequency) of the camera motor of the terminal. Further, the volume of the currently played audio may be acquired.
S203, determining a target current based on the volume and the frequency value of the audio, and controlling a coil of the camera motor to be connected with the target current.
It is understood that there is a correspondence between the volume (volume of audio), the frequency value of audio, and the current (current of the coil of the camera motor). This is because, when the current is passed through the coil, the ampere force generated by the coil can cancel the excitation of the camera vibration caused by the audio frequency, and the excitation generated by the camera vibration caused by the audio frequency is mainly determined by the frequency value and the volume of the audio frequency. Therefore, in the embodiment of the application, the audio frequency causing the vibration of the camera can be played in advance, the volume of the audio frequency is controlled, the current introduced into the coil is controlled at the same time, the current capable of offsetting the vibration of the camera, the frequency value of the audio frequency and the volume are recorded, and the corresponding relation among the current, the frequency value and the volume is stored. Generally, when the frequency value of the audio is fixed, the volume of the audio can be adjusted from the lowest value to the highest value, in the adjusting process, the vibration condition of the camera is observed, and the current led into the coil is controlled, so that the volume which can cause the camera to vibrate has a current value corresponding to the volume (can counteract the camera vibration). Further, in the practical application process, after the frequency value and the volume of the played audio are determined, the target current corresponding to the frequency value and the volume can be searched from the determined corresponding relation, and then the target current is introduced into the coil of the camera motor, so that the camera vibration can be eliminated.
When the scheme of the embodiment of the application is executed, under the condition that a camera collects images, the frequency value of the audio currently played by the terminal is obtained, if the frequency value of the audio is determined to be the same as the frequency value of the vibration frequency of the camera motor, the volume of the audio is obtained, a target current is determined based on the volume and the frequency value of the audio, and the coil of the camera motor is controlled to be connected with the target current. This application lets in the electric current through the coil at the camera motor for the ampere power that the coil current produced can offset the outside power that receives of camera (that the audio frequency that the speaker broadcast arouses), that is to say, can eliminate the camera because the camera lens vibration that outside atress arouses, and then can avoid the camera because the camera lens vibration appears the problem of picture shake when gathering the picture.
Referring to fig. 3, a schematic flow chart of a camera control method according to an embodiment of the present disclosure is shown, where the method according to the embodiment of the present disclosure may include the following steps:
s301, controlling a coil of a camera motor to be in a non-electrified current state, and respectively playing audio corresponding to each preset frequency value.
It will be appreciated that the preset frequency value may be a frequency value in the frequency range of 20Hz to 20 KHz.
In some embodiments, the coil in the camera motor may be controlled to be in a non-current state, that is, if the current connected to the coil is 0, the coil cannot generate an ampere force, and in this state, the audio corresponding to each preset frequency value may be played through the speaker of the terminal, that is, the frequency value of the played audio is the preset frequency value. Specifically, since only one audio with a preset frequency value can be played in the same time period, the audio with different preset frequency values can be played randomly and in different time periods.
S302, determining the vibration state of a first image acquired by a camera under each audio frequency, and determining a preset frequency value set corresponding to a camera motor in each preset frequency value based on the vibration state of the first image.
It can be understood that the frequency value in the preset set of frequency values is a frequency value that can be a vibration frequency of the camera motor, i.e. a frequency value of a natural frequency of the camera motor, where the natural frequency is a specific frequency determined only by the properties of the system when the structural system is excited by the outside to generate motion.
The first image may be an image collected by the camera when the terminal plays audio.
The vibration state may include a vibration state and a non-vibration state.
In some embodiments, during the process that the terminal is playing an audio, the camera may capture one or more first images, and then the terminal may determine a vibration state of the first images, that is, determine whether the first images are in a vibration state or a non-vibration state, where the first images are in a vibration state to indicate that there is a picture shaking problem in the first images (the camera vibrates, which causes the captured images to have a picture shaking problem), and the first images are in a non-vibration state to indicate that there is no picture shaking problem in the first images (the camera does not vibrate, which causes the captured images to have no picture shaking problem). As for the manner of determining the vibration state of the first image, there may be two determination manners: firstly, a manual judgment mode is adopted, in the application scene shown in fig. 1, a first image acquired by a camera of a terminal (a first terminal) can be displayed on a second terminal, a technician can observe the first image on the second terminal and then judge the vibration state of the first image, the technician can feed the vibration state of the first image back to the second terminal, and further, the second terminal can send the vibration state of the first image to the terminal, and the terminal can determine the vibration state of the first image; and secondly, an automatic judgment mode is adopted, after the camera collects the first image, the terminal can identify the data of the first image by utilizing the self-configured algorithm, can identify the displacement change and the like of the object in the first image in a short time, and then judges the vibration state of the first image. Further, according to the judgment result of the vibration state of the first image, a preset frequency value of an audio frequency played by the first image with the vibration state when being collected is used as a frequency value in a preset frequency value set. It should be noted that, for the case that only one first image is acquired, only the vibration state of the first image may be determined; for the case that a plurality of first images are collected, the vibration states of the plurality of first images can be judged, when the number of the images in the vibration states exceeds a number threshold value, a preset frequency value of an audio frequency can be used as a frequency value in a preset frequency value set, and the accuracy of vibration state judgment can be improved through diversity by collecting the plurality of first images.
S303, respectively playing the test audio corresponding to each frequency value in the preset frequency value set.
S304, sequentially adjusting the volume of each test audio according to a preset volume range to obtain each test volume, and determining the vibration state of the second image acquired by the camera under the test audio corresponding to each test volume.
And S305, controlling a coil of the camera motor to be connected with each preset current based on the vibration state of the second image, and determining the vibration state of a third image acquired by the camera under each preset current.
And S306, determining a test current corresponding to the test volume in the preset currents based on the vibration state of the third image.
S303 to S306 will be explained below.
It will be appreciated that the test audio may be audio having frequency values that are frequency values from a set of preset frequency values.
The preset volume range refers to a volume range from the minimum volume value to the maximum volume value on the terminal.
The second image may be an image collected by the camera when the terminal plays the test audio of the test volume. The vibration state of the second image may be a vibration state of the second image and a non-vibration state of the second image.
The third image can be an image collected when the camera plays a test audio of the test volume at the terminal and a coil of a motor of the camera is connected with a preset current. The vibration state of the third image may be a vibration state of the third image and a non-vibration state of the third image.
The preset current can be preset current values with different magnitudes.
It should be noted that, S303 to S306 describe the execution steps of playing a plurality of test audios, only one test audio can be played in the same time period, and the following explanation takes playing one test audio as an example: playing a test audio corresponding to one frequency value in a preset frequency value set, adjusting the volume of the test audio according to a preset volume range to obtain a plurality of test volumes, determining the vibration state of a second image acquired by a camera under the test audio corresponding to the plurality of test volumes, controlling a coil of a motor of the camera to be connected with each preset current based on the vibration state of the second image, determining the vibration state of a third image under each preset current, and determining the test current corresponding to the test volume in each preset current based on the vibration state of the third image. And playing the test audio corresponding to other frequency values in the preset frequency value set respectively, and repeating the operation in sequence until all the vibration frequencies are finished executing the operation.
Specifically, when the terminal plays the test audio corresponding to one frequency value in the preset frequency value set, the volume of the test audio may be adjusted from the minimum volume value to the maximum volume value. In the process of adjusting the volume, when a test volume is obtained by each adjustment, that is, when the terminal plays the test audio of the test volume, the vibration state of the second image acquired by the camera may be determined, and the specific vibration state determination method may refer to the description process in S302, which is not described herein again. When the vibration state of the second image is determined to be a vibration state, sequentially passing each preset current into a coil of a camera motor; when the vibration state of the second image is determined to be a non-vibration state, the current in the coil may not be changed, and the current currently supplied to the coil may be maintained. Further, when the coil is supplied with the preset current, the terminal also plays the test audio of the test volume, and at this time, the vibration state of the third image acquired by the camera may be determined, and the specific vibration state determination method may refer to the description process in S302, which is not described herein again. And taking the preset current introduced into the coil as the test current corresponding to the test volume only when the vibration of the third image is determined to be in a non-vibration state.
It can be understood that, the process of sequentially passing each preset current through the coil may specifically be that the preset current may be sequentially passed through the coil according to a sequence of current values from large to smallAnd when each preset current is input, the vibration state of the third image acquired by the camera can be determined after each current is input, the process of inputting the preset current can be stopped after the vibration state of the third image is determined to be a non-vibration state, and the currently input preset current is used as the test current. Determining that the vibration state of the third image is a non-vibration state means that the current test current is introduced into the coil, and the ampere force generated by the coil can counteract the external force brought to the camera by the test audio under the current test volume. This is because a system constituted by a Voice Coil Motor (VCM) can be understood as an undamped single degree of freedom system, that is, mx "+ kx ═ F 0 e jwt If F cannot be cancelled out 0 e jwt The external excitation that causes will arouse the vibration of VCM shell fragment, and this scheme changes the electric current in the VCM coil for ampere force can offset the excitation of audio vibration, can accomplish vibration isolation, namely F gets 1 ＝BIL＝F 0 e jwt In the formula F 1 The excitation represents the ampere force generated by the coil, B represents the magnetic induction intensity, I represents the current led in the coil, L represents the length of the coil, and w represents the frequency value of the audio frequency.
S307, establishing a mapping table among the frequency value corresponding to the test audio, the test volume corresponding to the test audio and the test current corresponding to the test volume.
From the above description, it can be seen that the ampere force is able to cancel the excitation of the audio vibration, i.e. F 1 ＝BIL＝F 0 e jwt Further, I ═ F can be obtained 0 e jwt BL, let A ═ F 0 BL, in turn, can obtain I ═ Ae jwt In the formula, a represents the amplitude, usually the amplitude is determined by the volume of the audio, V represents the volume, a in the formula may be replaced by λ V, and the relationship between the current and the volume and frequency values, i.e., I ═ λ Ve, may be obtained jwt . Therefore, based on the frequency value corresponding to the test audio obtained in S303 to S306, the test volume of the test audio, and the test current corresponding to the test volume, a mapping table between the three may be established, and the mapping table may be stored locally in the terminal.
S308, when the camera collects the image, whether the terminal is in a state of transmitting the image in real time is detected, and if yes, the frequency value of the audio currently played by the terminal is obtained.
In some embodiments, the terminal may play audio while the camera collects the image, and further, the terminal may store the image collected by the camera locally, or may transmit the image collected by the camera to another terminal or a server. In the scheme, when the terminal is determined to be in a state of transmitting the image acquired by the camera to other terminals in real time, the frequency value of the audio currently played by the terminal can be acquired. For the mode of obtaining the frequency value of the audio, if the terminal stores the relevant information of the audio, the frequency value of the audio can be searched from the relevant information; if the terminal does not store the relevant information of the audio, the audio can be identified by adopting a pre-trained frequency identification model, so that the frequency value of the audio can be obtained. Therefore, when the terminal is in a state of implementing image transmission, the steps of the scheme are executed, and the resources of the terminal can be saved.
S309, when the frequency value is detected to be in the preset frequency value set, determining that the frequency value is the same as the frequency value of the vibration frequency of the camera motor, and acquiring the volume of the audio.
In some embodiments, according to the preset frequency value set obtained in S301 to S302, it may be detected whether the frequency value of the audio is in the preset frequency value set, where the specific detection manner may be to determine whether a frequency value equal to the frequency value of the audio exists in the preset frequency value set, and if the frequency value equal to the frequency value of the audio exists, it may be determined that the frequency value of the audio is equal to the frequency value of the vibration frequency of the camera motor, that is, the audio may cause the camera to vibrate, and then obtain the volume of the audio.
S310, determining a test current corresponding to the frequency values of the volume and the audio in the mapping table, taking the test current as a target current, and controlling a coil of the camera motor to be connected with the target current.
In some embodiments, according to the mapping table obtained in S306, the value of the volume may be used as a value of a test volume in the mapping table, the frequency value of the audio frequency may be used as a frequency value in the mapping table, and then, according to the determined frequency value and the test volume, a test current corresponding to the frequency value and the test volume at the same time may be searched in the mapping table, and further, the test current may be used as a target current corresponding to the camera motor, and the target current is passed through a coil of the camera motor.
S311, when the frequency value of the audio is not detected to be in the preset frequency value set, determining that the frequency value of the audio is different from the frequency value of the vibration frequency of the camera motor, and controlling a coil in the camera motor to keep the current which is currently conducted.
In some embodiments, according to the preset frequency value set obtained in S301 to S302, it may be detected whether the frequency value of the audio frequency is in the preset frequency value set, where the specific detection manner may be that whether a frequency value equal to the frequency value of the audio frequency exists in the preset frequency value set is determined, and if the frequency value does not exist, it may be determined that the frequency value of the audio frequency is not equal to the frequency value of the vibration frequency of the camera motor, that is, the audio frequency does not cause the camera to vibrate, the exterior of the camera is not excited by the audio frequency, and an ampere force generated by the coil is not required to counteract the excitation, so that a current currently passed through the coil is not changed, that is, the coil in the camera motor is controlled to maintain the current passed through the coil.
When the scheme of the embodiment of the application is executed, firstly, under the state that no current is conducted in the coil of the camera motor, the frequency values of the vibration frequency causing the camera to vibrate are obtained through testing, the frequency values can form a preset frequency value set, then, the audio frequency corresponding to each frequency value in the preset frequency value set is played, the external excitation of the camera is tested by adjusting the volume of the audio frequency, and the corresponding current is conducted in the coil, so that the ampere force generated by the coil can counteract the external excitation of different sizes, and therefore, the current value for eliminating the external excitation of the camera can be obtained. In practical application, namely the camera collects images, the terminal is in a state of transmitting the images, and under the condition that the terminal plays audio, a proper current value can be selected from the current values measured in advance according to the frequency value and the volume of the audio and is led into a coil of a motor of the camera. In the testing process, the whole process only involves playing audio, adjusting volume and changing current, and in the application process, only the current value introduced into the coil needs to be selected according to the frequency value and the volume of the audio, so that the ampere force generated by the coil eliminates the external excitation on the camera, a physical isolation external excitation mode is not needed, the cost for increasing physical vibration reduction can be saved, and the problem of picture jitter caused by lens vibration when the camera collects a picture can be avoided.
