技术领域technical field
本发明涉及移动通信技术领域，并且更具体地，涉及一种移动终端音圈马达的控制方法及移动终端。The present invention relates to the technical field of mobile communication, and more specifically, to a method for controlling a voice coil motor of a mobile terminal and the mobile terminal.
背景技术Background technique
如今很多移动终端的摄像头都带有自动对焦功能。最常用的自动对焦是反差式对焦，通过音圈马达带动摄像头移动，不断改变焦点的位置，找到画面最清晰的位置，从而完成自动对焦。Nowadays, the cameras of many mobile terminals have an auto-focus function. The most commonly used auto-focus is the contrast-type focus. The voice coil motor drives the camera to move, constantly changes the focus position, and finds the clearest position to complete the auto-focus.
用户在使用移动终端时，经常会出现无意中打开拍照功能却没有进行拍照的情况，譬如，移动终端放在口袋中误触发拍照功能，或拍照后忘记关闭拍照应用等。如果开启了摄像头又没有进行拍照，则会根据物距的变化不断驱动音圈马达进行自动对焦，这将产生较大的电量消耗。When using a mobile terminal, the user often turns on the camera function unintentionally but does not take a picture. For example, the mobile terminal is placed in the pocket to trigger the camera function by mistake, or the camera application is forgotten to be closed after taking a picture. If the camera is turned on and no photo is taken, the voice coil motor will be continuously driven to autofocus according to the change of the object distance, which will consume a lot of power.

具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
第一实施例first embodiment
图1为本发明第一实施例的移动终端音圈马达的控制方法流程图，包括以下步骤：FIG. 1 is a flow chart of a control method for a mobile terminal voice coil motor according to a first embodiment of the present invention, including the following steps:
步骤101：检测移动终端是否切换到预拍照状态。Step 101: Detect whether the mobile terminal switches to the pre-photographing state.
本步骤101中，移动终端切换到预拍照状态可以是与摄像头相关的应用被开启，并进入了拍照预览界面，从原先的非拍照状态切换到预拍照状态。这里的非拍照状态可以是待机状态，也可以是部分应用正在运行的状态，还可以是其他摄像头未开启，且未进入拍照预览界面的状态，本发明实施例在此不作限制。In this step 101, the switching of the mobile terminal to the pre-photographing state may be that the application related to the camera is opened, and enters the photo-taking preview interface, and switches from the original non-photographing state to the pre-photographing state. The non-photographing state here may be a standby state, or a state in which some applications are running, or a state in which other cameras are not turned on and have not entered the photo preview interface, which is not limited in this embodiment of the present invention.
步骤102：如果所述移动终端切换到预拍照状态，判断所述移动终端是否处于未使用状态。Step 102: If the mobile terminal switches to a pre-photographing state, determine whether the mobile terminal is in an unused state.
本步骤102中的未使用状态是指用户未使用移动终端进行操作的状态。具体地，未使用状态可以是面向所述移动终端的触摸屏的预设距离范围内存在物体，如移动终端前方预设距离内有遮挡，也可以是所述移动终端的摄像头预设距离范围内的环境光强度小于预设强度，如摄像头被遮挡，也可以是所述移动终端在预设方向上有预设的加速度或位移，如移动终端产生幅度较大的晃动等。这些状态可以通过移动终端的距离传感器、摄像头感光元件或加速度传感器等进行检测，本发明实施例在此不作限定。The unused state in step 102 refers to a state in which the user does not use the mobile terminal to perform operations. Specifically, the unused state may be that there is an object within a preset distance range facing the touch screen of the mobile terminal, such as an obstruction within a preset distance in front of the mobile terminal, or an object within a preset distance range of the camera of the mobile terminal. The ambient light intensity is less than the preset intensity, for example, the camera is blocked, or the mobile terminal has a preset acceleration or displacement in the preset direction, for example, the mobile terminal shakes to a large extent. These states may be detected by a distance sensor, a photosensitive element of a camera, or an acceleration sensor of the mobile terminal, which is not limited in this embodiment of the present invention.
步骤103：如果所述移动终端处于未使用状态，则对所述移动终端的音圈马达的驱动电流进行调整，使所述音圈马达回到切换到预拍照状态之前所处的位置。Step 103: If the mobile terminal is not in use, adjust the driving current of the voice coil motor of the mobile terminal, so that the voice coil motor returns to the position it was in before switching to the pre-photographing state.
本步骤103中，对音圈马达的驱动电流进行的调整可以是直接将驱动关闭使驱动电流值为零，即对音圈马达进行断电，也可以是将驱动电流减小到一个预设的电流值，还可以是其他对驱动电流的大小进行的调整，本发明实施例在此不作限定。In this step 103, the adjustment of the driving current of the voice coil motor can be directly turning off the driving to make the driving current value zero, that is, powering off the voice coil motor, or reducing the driving current to a preset value. The current value can also be other adjustments to the magnitude of the driving current, which is not limited in this embodiment of the present invention.
值得注意的是，音圈马达在切换到预拍照状态之前所处的位置，具体为移动终端摄像头处于非拍照状态下音圈马达所处的原始位置，这里的非拍照状态可以是待机状态，也可以是部分应用正在运行的状态，还可以是其他摄像头未开启，且未进入拍照预览界面的状态，本发明实施例在此不作限制。It is worth noting that the position of the voice coil motor before switching to the pre-photographing state is specifically the original position of the voice coil motor when the camera of the mobile terminal is in the non-photographing state. The non-photographing state here can be the standby state, or It may be a state that some applications are running, or it may be a state that other cameras are not turned on and have not entered the photo preview interface, which is not limited in this embodiment of the present invention.
本发明实施例通过检测到移动终端摄像头开启却没有使用的状态时，对音圈马达的驱动电流进行调整，解决了无意开启了摄像头却没有使用摄像头拍照时，由于音圈马达不断自动对焦造成的耗电量增加的问题，减少了移动终端的耗能，增加了待机时长。The embodiment of the present invention adjusts the driving current of the voice coil motor by detecting that the camera of the mobile terminal is turned on but not in use, so as to solve the problem caused by the continuous auto-focus of the voice coil motor when the camera is unintentionally turned on but not used to take pictures. The problem of increased power consumption reduces the power consumption of the mobile terminal and increases the standby time.
第二实施例second embodiment
图2为本发明第二实施例的实现移动终端音圈马达的控制方法流程图，包括以下步骤：FIG. 2 is a flow chart of a control method for realizing a mobile terminal voice coil motor according to a second embodiment of the present invention, including the following steps:
步骤201：检测移动终端是否切换到预拍照状态。Step 201: Detect whether the mobile terminal switches to a pre-photographing state.
本步骤201中，移动终端切换到预拍照状态具体是与摄像头相关的应用被开启，并进入了拍照预览界面，从原先的非拍照状态切换到预拍照状态。其中，这里的非拍照状态可以是待机状态，也可以是部分应用正在运行的状态，还可以是其他摄像头未开启，且未进入拍照预览界面的状态，本发明实施例在此不作限制。具体地，可以通过检测与摄像头相关的控制芯片的电源是否接通来判断移动终端是否开启了摄像头，或通过识别移动终端的摄像头获取周围环境图像并显示在界面上来判断是否进入了拍照预览界面。例如，移动终端检测到摄像头控制芯片通电或移动终端触摸屏界面显示摄像头获取的周围环境的图像，则可以认为移动终端切换到了预拍照状态。In this step 201, the mobile terminal switches to the pre-photographing state, specifically, the application related to the camera is opened, and enters the photo-taking preview interface, and switches from the original non-photographing state to the pre-photographing state. Wherein, the non-photographing state here may be a standby state, or a state in which some applications are running, or a state in which other cameras are not turned on and have not entered the photo preview interface, which is not limited in this embodiment of the present invention. Specifically, it can be judged whether the mobile terminal has turned on the camera by detecting whether the power supply of the control chip related to the camera is turned on, or whether the camera preview interface has been entered by identifying the camera of the mobile terminal to capture the surrounding environment image and displaying it on the interface. For example, if the mobile terminal detects that the camera control chip is powered on or the touch screen interface of the mobile terminal displays the image of the surrounding environment captured by the camera, it can be considered that the mobile terminal has switched to the pre-photographing state.
步骤202：如果所述移动终端切换到预拍照状态，判断所述移动终端是否处于未使用状态。Step 202: If the mobile terminal switches to a pre-photographing state, determine whether the mobile terminal is in an unused state.
其中，本步骤202中的未使用状态为面向所述移动终端的触摸屏的预设距离内存在物体，或所述移动终端的摄像头预设距离范围内的环境光强度小于预设强度，或所述移动终端在预设方向上有预设的加速度或位移。Wherein, the unused state in this step 202 is that there is an object within the preset distance facing the touch screen of the mobile terminal, or the ambient light intensity within the preset distance range of the camera of the mobile terminal is less than the preset intensity, or the The mobile terminal has a preset acceleration or displacement in a preset direction.
移动终端的未使用状态可以是面向所述移动终端的触摸屏的预设距离内存在物体，即移动终端处于触摸屏被遮挡的情况，如移动终端被用户放在口袋里、触摸屏朝下倒扣在桌面等，因此可以从面向移动终端触摸屏的方向上进行是否存在物体的检测，如果存在物体遮挡，则进一步获取该物体与移动终端的触摸屏的距离，并判断该距离是否小于预设距离，如果该距离小于预设距离，则移动终端处于未使用状态。The unused state of the mobile terminal can be that there is an object within a preset distance facing the touch screen of the mobile terminal, that is, the mobile terminal is in a situation where the touch screen is blocked, such as the mobile terminal is placed in the user's pocket and the touch screen is turned upside down on the desktop Etc. Therefore, it is possible to detect whether there is an object from the direction facing the touch screen of the mobile terminal. If there is an object occlusion, then further obtain the distance between the object and the touch screen of the mobile terminal, and judge whether the distance is less than the preset distance. If the distance If the distance is less than the preset distance, the mobile terminal is in an unused state.
具体地，可以利用距离传感器判断面向所述移动终端的触摸屏的预设距离内是否存在物体。这里的距离传感器可以是感应型距离传感器、超声波距离传感器、光电型距离传感器等，本发明实施例在此不作限定。Specifically, a distance sensor may be used to determine whether there is an object within a preset distance facing the touch screen of the mobile terminal. The distance sensor here may be an inductive distance sensor, an ultrasonic distance sensor, a photoelectric distance sensor, etc., which are not limited in this embodiment of the present invention.
移动终端的未使用状态也可以是移动终端摄像头预设距离范围内的环境光强度小于预设强度，即摄像头被遮挡的情况，如移动终端触摸屏朝上或朝下放在桌面等，因此可以对后置或前置摄像头分别进行是否被遮挡光线的检测，并判断后置或前置摄像头周围的环境光强度是否小于预设强度。The unused state of the mobile terminal can also be that the ambient light intensity within the preset distance range of the mobile terminal camera is less than the preset intensity, that is, the situation where the camera is blocked, such as the mobile terminal touch screen facing up or down on the desktop, etc., so the rear The front camera or the front camera respectively detects whether the light is blocked, and judges whether the ambient light intensity around the rear camera or the front camera is less than the preset intensity.
具体地，可以利用摄像头的感光元件或拍照预览界面的图像质量检测摄像头周围的环境光强度。如果是利用感光元件，则通过检测感光元件的进光量来获取环境光强度，进而判断当前环境光强度是否小于预设强度，如果当前环境光强度小于预设强度，则移动终端处于未使用状态；如果是利用拍照预览界面，则可以通过计算拍照预览界面中显示的当前环境图像的平均亮度值，并跟与预设强度值相对应的图像平均亮度值作对比，从而判断当前环境光强度是否小于预设强度，如果当前环境光强度小于预设强度，则移动终端处于未使用状态。Specifically, the ambient light intensity around the camera can be detected by using the photosensitive element of the camera or the image quality of the photo preview interface. If the photosensitive element is used, the ambient light intensity is obtained by detecting the light input amount of the photosensitive element, and then it is judged whether the current ambient light intensity is less than the preset intensity. If the current ambient light intensity is less than the preset intensity, the mobile terminal is in an unused state; If you use the photo preview interface, you can calculate the average brightness value of the current environment image displayed in the photo preview interface, and compare it with the image average brightness value corresponding to the preset intensity value, so as to determine whether the current ambient light intensity is less than Preset intensity, if the current ambient light intensity is less than the preset intensity, the mobile terminal is in an unused state.
移动终端的未使用状态也可以是移动终端在预设方向上有预设的加速度或位移，即处于运动中的情况，如用户走动时将移动终端拿在手中、放在包里使移动终端晃动等。值得注意的是，这里的运动中的情况不包括移动终端与环境相对静止的运动，如用户在交通工具上使用手机、在走动中使用手机等。The unused state of the mobile terminal can also be that the mobile terminal has a preset acceleration or displacement in a preset direction, that is, a situation in which the mobile terminal is in motion, such as when the user walks around, holding the mobile terminal in his hand or putting it in a bag to make the mobile terminal shake Wait. It is worth noting that the situation in motion here does not include the relatively static motion between the mobile terminal and the environment, such as the user using a mobile phone on a vehicle, using a mobile phone while walking, and so on.
具体地，可以利用加速度传感器判断移动终端在预设方向上是否有预设的加速度或位移。通过加速度传感器获取移动终端的运动加速度和位移，根据运动加速度和位移的变化判断移动终端是否有晃动，如果移动终端的运动加速度小于预设的加速度值，或移动终端的位移值小于预设的位移值，则认为移动终端没有发生晃动；如果移动终端的运动加速度大于或等于预设的加速度值，且移动终端的位移值大于或等于预设的位移值，则认为移动终端发生了晃动，进而判定移动终端处于未使用状态。Specifically, an acceleration sensor may be used to determine whether the mobile terminal has a preset acceleration or displacement in a preset direction. Obtain the motion acceleration and displacement of the mobile terminal through the acceleration sensor, and judge whether the mobile terminal is shaking according to the change of motion acceleration and displacement. If the motion acceleration of the mobile terminal is less than the preset acceleration value, or the displacement value of the mobile terminal is less than the preset displacement value, it is considered that the mobile terminal has not shaken; if the motion acceleration of the mobile terminal is greater than or equal to the preset acceleration value, and the displacement value of the mobile terminal is greater than or equal to the preset displacement value, it is considered that the mobile terminal has shaken, and then judge The mobile terminal is not in use.
步骤203：如果所述移动终端处于未使用状态，则对所述移动终端的音圈马达进行断电，使所述音圈马达回到切换到预拍照状态之前所处的位置。Step 203: If the mobile terminal is not in use, power off the voice coil motor of the mobile terminal, so that the voice coil motor returns to the position it was in before switching to the pre-photographing state.
具体地，对音圈马达进行断电，即将音圈马达的驱动电流设为零，音圈马达由于失去由驱动电流产生的作用力而自动返回切换到预拍照状态之前所处的位置。Specifically, the voice coil motor is powered off, that is, the driving current of the voice coil motor is set to zero, and the voice coil motor automatically returns to the position before switching to the pre-photographing state due to the loss of the force generated by the driving current.
其中，移动终端在切换到预拍照状态之前音圈马达所处的位置为未通电时音圈马达所在的初始位置。例如，当音圈马达为中置式马达时，初始位置是中间位置；当音圈马达为传统马达时，初始位置是最底端的位置。Wherein, the position of the voice coil motor before the mobile terminal switches to the pre-photographing state is the initial position of the voice coil motor when it is not powered on. For example, when the voice coil motor is a mid-mounted motor, the initial position is the middle position; when the voice coil motor is a conventional motor, the initial position is the bottommost position.
本步骤203通过在移动终端处于未使用状态时对音圈马达进行断电，有效地阻止了在摄像头没有进行拍照时由于音圈马达不断自动对焦而造成的无意义的电能消耗。In this step 203, by powering off the voice coil motor when the mobile terminal is not in use, it effectively prevents meaningless power consumption caused by continuous auto-focusing of the voice coil motor when the camera is not taking pictures.
可选地，在对所述移动终端的音圈马达进行断电，使所述音圈马达回到切换到预拍照状态之前所处的位置步骤之后，继续判断移动终端是否处于使用状态，这里的使用状态可以为面向所述移动终端的触摸屏的预设距离内不存在物体，且所述移动终端的摄像头预设距离范围内的环境光强度大于或等于所述预设强度，且所述移动终端在所述预设方向上没有所述预设的加速度或位移。本发明实施例的使用状态指用户有对移动终端进行操作的状态。Optionally, after the voice coil motor of the mobile terminal is powered off, and the voice coil motor is returned to the position it was in before switching to the pre-photographing state, continue to determine whether the mobile terminal is in use, where The use state may be that there is no object within a preset distance facing the touch screen of the mobile terminal, and the ambient light intensity within the preset distance range of the camera of the mobile terminal is greater than or equal to the preset intensity, and the mobile terminal There is no said preset acceleration or displacement in said preset direction. The use state in the embodiment of the present invention refers to a state in which the user operates the mobile terminal.
如果移动终端处于使用状态，则对音圈马达重新上电，使所述音圈马达的位置根据拍照场景进行移动，实现自动对焦功能。If the mobile terminal is in use, the voice coil motor is powered on again, so that the position of the voice coil motor is moved according to the photographing scene to realize the automatic focusing function.
本发明实施例通过检测到移动终端摄像头被开启却没有使用的状态时，对音圈马达进行断电，解决了无意开启了摄像头却没有使用摄像头拍照时，由于音圈马达不断自动对焦造成的耗电量增加的问题，减少了移动终端的耗能，增加了待机时长。In the embodiment of the present invention, by detecting that the mobile terminal camera is turned on but not in use, the voice coil motor is powered off, which solves the power consumption caused by the continuous auto-focusing of the voice coil motor when the camera is unintentionally turned on but not used to take pictures. The problem of increased power reduces the energy consumption of the mobile terminal and increases the standby time.
第三实施例third embodiment
图3为本发明第三实施例的实现移动终端音圈马达的控制方法流程图，与第二实施例主要通过对音圈马达断电不同的是，第三实施例主要是将音圈马达的驱动电流调整至一个预设值。Fig. 3 is a flow chart of the control method for realizing the voice coil motor of the mobile terminal according to the third embodiment of the present invention. Unlike the second embodiment, which mainly cuts off the power of the voice coil motor, the third embodiment mainly uses the power of the voice coil motor The driving current is adjusted to a preset value.
第三实施例的所述音圈马达的控制方法，包括以下步骤：The control method of the voice coil motor of the third embodiment includes the following steps:
步骤301：检测移动终端是否切换到预拍照状态。Step 301: Detect whether the mobile terminal switches to the pre-photographing state.
本步骤301中，检测方法与本发明第二实施例中步骤201的检测方法相同，在这里不再赘述。In this step 301, the detection method is the same as the detection method in step 201 in the second embodiment of the present invention, and will not be repeated here.
步骤302：当检测到所述移动终端切换到预拍照状态时，判断所述移动终端是否处于未使用状态。Step 302: When it is detected that the mobile terminal has switched to a pre-photographing state, determine whether the mobile terminal is in an unused state.
本步骤302中的未使用状态为面向所述移动终端的触摸屏的预设距离内存在物体，或所述移动终端的摄像头预设距离范围内的环境光强度小于预设强度，或所述移动终端在预设方向上有预设的加速度或位移。具体的是否处于未使用状态的判断方法与第二实施例中步骤202的判断方法相同，在这里不再赘述。The unused state in step 302 is that there is an object within the preset distance facing the touch screen of the mobile terminal, or the ambient light intensity within the preset distance range of the camera of the mobile terminal is less than the preset intensity, or the mobile terminal There is a preset acceleration or displacement in a preset direction. The specific method for judging whether it is in an unused state is the same as the method for judging in step 202 in the second embodiment, and will not be repeated here.
步骤303：如果所述移动终端处于未使用状态，则将所述移动终端的音圈马达的驱动电流调整为一预设电流值，使所述音圈马达回到切换到预拍照状态之前所处的位置。Step 303: If the mobile terminal is not in use, adjust the driving current of the voice coil motor of the mobile terminal to a preset current value, so that the voice coil motor returns to the state before switching to the pre-photographing state s position.
具体地，当移动终端判断出移动终端处于未使用状态时，将音圈马达的驱动电流调整为一预设电流值，而音圈马达根据这个预设电流的驱动回到切换到预拍照状态之前所处的位置。其中，移动终端在切换到预拍照状态之前音圈马达所处的位置为未通电时音圈马达所在的初始位置。例如，当音圈马达为中置式马达时，初始位置是中间位置；当音圈马达为传统马达时，初始位置是最底端的位置。Specifically, when the mobile terminal determines that the mobile terminal is not in use, the driving current of the voice coil motor is adjusted to a preset current value, and the driving of the voice coil motor according to the preset current returns to the state before switching to the pre-photographing state. where you are. Wherein, the position of the voice coil motor before the mobile terminal switches to the pre-photographing state is the initial position of the voice coil motor when it is not powered on. For example, when the voice coil motor is a mid-mounted motor, the initial position is the middle position; when the voice coil motor is a conventional motor, the initial position is the bottommost position.
在本发明实施例中，预设电流值的设定与音圈马达的启动电流大小有关。由于要使音圈马达返回或保持在未通电时音圈马达所在的初始位置，暂停自动对焦，所以预设电流值小于音圈马达的启动电流。例如，移动终端所使用的音圈马达的启动电流为15mA，那么预设电流值可以设为10mA，也可以设为5mA，还可以是其他小于15mA，大于0的任意值，本发明实施例在此不作限定。In the embodiment of the present invention, the setting of the preset current value is related to the starting current of the voice coil motor. Since the voice coil motor needs to return or remain at the initial position where the voice coil motor is when no power is applied, and the auto-focus is suspended, the preset current value is smaller than the start-up current of the voice coil motor. For example, the starting current of the voice coil motor used in the mobile terminal is 15mA, then the preset current value can be set to 10mA, or 5mA, or any other value less than 15mA and greater than 0. This is not limited.
本步骤303通过将音圈马达的驱动电流调整到一个较小的预设值，在减少移动终端在未使用状态时自动对焦造成的耗电的同时，将音圈马达保持在通电状态，即保持音圈马达的驱动电流为上述预设电流值，恢复自动对焦时音圈马达不需要重新上电，提高了拍照的控制效率。In this step 303, by adjusting the driving current of the voice coil motor to a smaller preset value, while reducing the power consumption caused by auto-focusing when the mobile terminal is not in use, keep the voice coil motor in the power-on state, that is, keep the The driving current of the voice coil motor is the above-mentioned preset current value, and the voice coil motor does not need to be powered on again when the auto focus is restored, which improves the control efficiency of taking pictures.
步骤304：判断所述移动终端是否处于使用状态；如果所述移动终端处于所述使用状态，则根据所述预设电流值对所述音圈马达的驱动电流进行调整，使所述音圈马达的位置根据拍照场景进行移动。Step 304: Determine whether the mobile terminal is in use; if the mobile terminal is in use, adjust the driving current of the voice coil motor according to the preset current value, so that the voice coil motor The position of the camera is moved according to the shooting scene.
具体地，本发明实施例中的使用状态可以为面向所述移动终端的触摸屏的预设距离内不存在物体，且所述移动终端的摄像头预设距离范围的环境光强度大于或等于预设强度，且所述移动终端在所述预设方向上没有所述预设的加速度或位移。Specifically, the use state in the embodiment of the present invention may be that there is no object within a preset distance facing the touch screen of the mobile terminal, and the ambient light intensity within the preset distance range of the camera of the mobile terminal is greater than or equal to the preset intensity , and the mobile terminal does not have the preset acceleration or displacement in the preset direction.
具体地，判断移动终端是否处于使用状态的原理和本发明实施例的步骤302中判断移动终端是否处于未使用状态的原理相似，当移动终端处于使用状态时，在原来驱动电流的基础上增大驱动电流，而不是在断电的情况下重新上电，使音圈马达达到启动条件，并随着拍照场景的变化改变位置，进而实现自动对焦功能的恢复。Specifically, the principle of judging whether the mobile terminal is in use is similar to the principle of judging whether the mobile terminal is in the unused state in step 302 of the embodiment of the present invention. When the mobile terminal is in use, the driving current is increased on the basis of the original driving current. The driving current, instead of re-powering in the case of power failure, enables the voice coil motor to reach the starting condition, and changes its position with the change of the photographing scene, thereby realizing the recovery of the autofocus function.
可选地，本发明实施例的另一种实现方式如图4所示，步骤303之后包括步骤404：如果所述移动终端处于未使用状态的的时间大于一时间阈值，则对所述音圈马达进行断电。Optionally, another implementation manner of the embodiment of the present invention is shown in FIG. 4 , after step 303, step 404 is included: if the time that the mobile terminal is in the unused state is greater than a time threshold, the voice coil The motor is de-energized.
具体地，这里可以通过定时器获取移动终端处于未使用状态所持续的时间，并将获取到的时间与预设的时间阈值相比较，当移动终端持续处于未使用状态的时间大于这个时间阈值，则断开音圈马达的驱动电流。Specifically, the time during which the mobile terminal is in the unused state can be obtained through a timer here, and the obtained time is compared with a preset time threshold. When the time that the mobile terminal is continuously in the unused state is greater than this time threshold, Then the driving current of the voice coil motor is cut off.
这样避免了当移动终端长时间处于未使用状态时，由于音圈马达一直通电而产生的仍然在消耗电量的问题，进一步减小了耗能，增加移动终端的待机时长。In this way, when the mobile terminal is not in use for a long time, the problem of power consumption caused by the voice coil motor being powered on all the time is avoided, the energy consumption is further reduced, and the standby time of the mobile terminal is increased.
本发明实施例通过检测到移动终端摄像头开启却没有使用的状态时，将音圈马达的驱动电流调整至一预设电流值，解决了移动终端由于关闭音圈马达自动对焦导致的再次自动对焦时延迟较大的问题，在减少移动终端耗能的同时，提高了移动终端的使用效率和用户体验。The embodiment of the present invention adjusts the driving current of the voice coil motor to a preset current value by detecting that the camera of the mobile terminal is turned on but not in use, so as to solve the problem of re-autofocus caused by turning off the autofocus of the voice coil motor of the mobile terminal. In order to solve the problem of large delay, while reducing the energy consumption of the mobile terminal, the use efficiency and user experience of the mobile terminal are improved.
