[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The video recording method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] Please see Figure 1 , which is a flow chart of a video recording method provided in an embodiment of the present application. The method can be applied to an electronic device, which can be a mobile phone, a tablet computer, a laptop computer, etc. The electronic device includes a driving mechanism and an image sensor, and the driving mechanism can be a motor. When the driving mechanism or the image sensor is in the target position, the center of the driving mechanism coincides with the optical center of the image sensor. The electronic device also includes a lens module, and the driving mechanism is used to control the movement of the lens module, that is, when the driving mechanism or the image sensor is in the target position, the center of the driving mechanism, the optical center of the image sensor and the optical axis of the lens module coincide.

[0027] Usually, when using an electronic device to take pictures, if the electronic device shakes, that is, the image sensor of the electronic device shakes, the electronic device can control the lens module to move in the opposite direction of the shaking direction through a driving mechanism based on the shaking information, thereby eliminating the shaking and avoiding the generation of image ghosting.

[0028] However, for electronic devices with optical image stabilization function, since the image stabilization angle of the electronic device is limited, when the maximum image stabilization angle is exceeded, the electronic device no longer has the corresponding image stabilization function, which affects the shooting effect.

[0029] In order to solve the above problems, an embodiment of the present application provides a video recording method, which controls a driving mechanism or an image sensor to move to a target position before capturing the next frame of the video, so that the center of the driving mechanism, the optical center of the image sensor and the optical axis of the lens module coincide with each other, thereby avoiding the problem of blurred and unclear images caused by exceeding the maximum anti-shake angle during the recording process, thereby improving the recording effect.

[0030] Figure 1 The video recording method may include the following steps S1100 to S1300, which are described in detail below.

[0031] Step S1100, obtaining target parameters.

[0032] The target parameter is a parameter related to the target device moving to the target position. The target device includes a driving mechanism or an image processor.

[0033] For example, the target parameter includes at least a moving speed, which indicates a speed at which the target device moves toward the target location.

[0034] For another example, the target parameter may also include a movement ratio, which is used to limit the maximum distance that the target device can move to the target position.

[0035] In one example, obtaining the target parameters in step S1100 may further include the following steps S1110a to S1130a:

[0036] Step S1110a: receiving a first input for the shooting preview interface.

[0037] In this example, the electronic device includes a camera application, and the shooting preview interface is the interface displayed after entering the camera application. Here, the camera application can be entered in different ways, for example, the user can click the icon of the camera application displayed on the display screen of the electronic device to enter the shooting preview interface of the camera application. For another example, the camera application can be called through the camera calling interface of other applications to enter the shooting preview interface of the camera application during the process of running other applications in the electronic device.

[0038] The first input may be a touch input of a setting button on the shooting preview interface.

[0039] For example, Figure 2As shown, when the shooting preview interface is displayed, the shooting preview interface provides a setting button, and the photographer can click on the setting button.

[0040] Step S1120a: In response to the first input, a setting entry for setting the target parameters is provided.

[0041] In this example, when the shooting preview interface is displayed, the shooting preview interface provides a setting button, through which the photographer can set the video recording mode to the active anti-shake mode. On the other hand, the photographer can set the movement ratio and the movement speed through the setting button.

[0042] For example, after the photographer clicks on the setting button, the video recording mode will be displayed as active anti-shake mode in the upper right corner of the shooting preview interface. At the same time, a movement ratio selection bar is also provided in the upper right corner of the shooting preview interface. Furthermore, a movement ratio selection bar can also be provided in the upper right corner of the shooting preview interface.

[0043] Step S1130a, obtaining the target parameters input through the setting entry.

[0044] In this example, the photographer can input the desired value of the target parameter through the above setting entry.

[0045] For example, the photographer can select a desired movement ratio value through a selection bar for movement speed, and the photographer can also select a desired movement ratio value through a selection bar for movement ratio.

[0046] According to this example, a setting entry is provided for the photographer to select appropriate target parameters based on his or her own needs, thereby realizing the user's personalized needs.

[0047] In one example, obtaining the target parameters in step S1100 may further include the following steps S1110b to S1120b:

[0048] Step S1110b: acquiring the shooting scene while displaying the shooting preview interface.

[0049] In this example, the electronic device includes a camera application, and the shooting preview interface is the interface displayed after entering the camera application. Here, the camera application can be entered in different ways, for example, the user can click the icon of the camera application displayed on the display screen of the electronic device to enter the shooting preview interface of the camera application. For another example, the camera application can be called through the camera calling interface of other applications to enter the shooting preview interface of the camera application during the process of running other applications in the electronic device.

[0050] In this example, when the shooting preview interface is displayed, the shooting preview interface provides a setting button, through which the photographer can set the video recording mode to the active anti-shake mode. At the same time, when the shooting preview interface is displayed, the shooting scene will be obtained.

[0051] The shooting scene may be a low-brightness scene, a high-brightness scene, or the state of the shooting object. The state of the shooting object may be that the shooting object is in a moving state.

[0052] Step S1120b, obtaining target parameters matching the shooting scene.

[0053] In this example, mapping data of mapping relationships between different shooting scenes and parameter values ​​of target parameters are pre-stored in the electronic device.

[0054] For example, for low-brightness scenes, when the target parameter includes a moving speed, the moving speed can be set larger, that is, a low-brightness scene corresponds to a larger moving speed. When the target parameter also includes a moving ratio, the moving speed can be set larger and the moving ratio can be set smaller, that is, a low-brightness scene corresponds to a larger moving speed and a smaller moving ratio.

[0055] For another example, for a high-brightness scene, if the target parameter includes a moving speed, the moving speed can be set to be smaller, that is, a small moving speed corresponds to a high-brightness scene. If the target parameter also includes a moving ratio, the moving speed can be set to be smaller and the moving ratio can be set to be larger, that is, a small moving speed and a large moving ratio correspond to a high-brightness scene.

[0056] For another example, if the object is in a motion scene, when the target parameter includes the moving speed, the moving speed can be set to be larger, that is, a larger moving speed corresponds to the running scene. If the target parameter also includes the moving ratio, both the moving speed and the moving ratio can be set to be larger, that is, a larger moving speed and moving ratio corresponds to the motion scene.

[0057] According to this example, the parameter value of the target parameter is automatically set according to the identified shooting scene, so that the parameter value of the set target parameter can match the shooting scene.

[0058] In one example, obtaining the target parameters in step S1100 may further include the following steps S1110c to S1130c:

[0059] Step S1110c: when the shooting preview interface is displayed, obtain the facial image of the photographer.

[0060] In this example, the electronic device includes a camera application, and the shooting preview interface is the interface displayed after entering the camera application. Here, the camera application can be entered in different ways, for example, the user can click the icon of the camera application displayed on the display screen of the electronic device to enter the shooting preview interface of the camera application. For another example, the camera application can be called through the camera calling interface of other applications to enter the shooting preview interface of the camera application during the process of running other applications in the electronic device.

[0061] In this example, when the shooting preview interface is displayed, the shooting preview interface provides a setting button, through which the shooter can set the video recording mode to the active anti-shake mode. At the same time, the front camera of the electronic device will capture the shooter's face image.

[0062] Step S1120c, matching the facial image with a preset image database.

[0063] The image database at least stores the face image of the professional photographer.

[0064] In this example, after acquiring the facial image of the photographer, the electronic device can recognize the facial features in the facial image and search for a facial image matching the recognized facial features in a preset image database.

[0065] In this example, a similarity threshold can be set to compare the similarity between the facial features and the facial images in the user database. If the similarity is greater than or equal to the similarity threshold, it indicates that the facial image in the image database matches the facial features identified.

[0066] Step S1130c, when a face image is matched, the first parameter corresponding to the face image is used as the target parameter; when a face image is not matched, the second parameter corresponding to the face image is used as the target parameter.

[0067] For example, the target parameter includes a moving speed. If a face image is matched, a first moving speed corresponding to the face image may be used as the moving speed. If a face image is not matched, a second moving speed corresponding to the face image may be used as the moving speed. Furthermore, the first moving speed is less than the second moving speed.

[0068] It can be understood that, when a face image is matched, it indicates that the photographer is a professional photographer. In the case where the target parameter includes the moving speed, the moving speed can be set to be smaller, that is, a professional photographer corresponds to a smaller moving speed (first moving speed). In the case where a face image is not matched, it indicates that the photographer is a non-professional photographer. In the case where the target parameter includes the moving speed, the moving speed can be set to be larger, that is, a non-professional photographer corresponds to a larger moving speed (second moving speed).

[0069] For another example, the target parameter also includes a movement ratio. When a face image is matched, the first movement speed and the first movement ratio corresponding to the face image can be used as the movement speed and the movement ratio. When a face image is not matched, the second movement speed and the second movement ratio corresponding to the face image can be used as the movement speed and the movement ratio. In addition, the first movement speed is less than the second movement speed, and the first movement ratio is less than the second movement ratio.

[0070] It can be understood that, when a face image is matched, it indicates that the photographer is a professional photographer. In the case where the target parameter also includes the movement ratio, the movement speed and the movement ratio can be set to be smaller, that is, a professional photographer corresponds to a smaller movement speed and movement ratio (first movement speed and first movement ratio). In the case where a face image is not matched, it indicates that the photographer is a non-professional photographer. In the case where the target parameter also includes the movement ratio, the movement speed and the movement ratio can be set to be larger, that is, a non-professional photographer corresponds to a larger movement speed (second movement speed and second movement ratio).

[0071] According to this example, it will determine whether the identified photographer is a professional photographer, and if the photographer is a professional photographer, it indicates that the shaking during the video recording is usually small, so the value of the target parameter is automatically set to a small value. For non-professional photographers, it indicates that the shaking during the video recording is usually large, so the value of the target parameter is automatically set to a large value, so that the shooting effect will be better.

[0072] After obtaining the target parameters, enter:

[0073] Step S1200 , during the video recording process, when the exposure end time of the current frame image of the video is reached, the target device is controlled to move toward a target position according to the target parameter.

[0074] The target device may be a driving mechanism or an image sensor.

[0075] In this embodiment, by controlling the driving mechanism or the image sensor to move toward the target position, the center of the driving mechanism, the optical center of the image sensor and the optical axis center of the lens module can be made to coincide, so that the electronic device has a maximum anti-shake angle when shooting each frame of the image.

[0076] During the video recording process, different frames of the video are shot with the same exposure parameters. The exposure parameters may be exposure time. That is, during the video recording process, different frames of the video are shot with the same exposure time. For a certain shooting frame rate, the frame length is certain, and the frame length of each frame includes the exposure time and the readout time of each frame. When the sum of the exposure time and the readout time of each frame is less than the frame length of each frame, the remaining time is the idle time. In other words, there is a certain idle time between two frames of images. Based on this, during the idle time between shooting two frames of images, controlling the drive mechanism or the image sensor to move to the target position can ensure that the electronic device has the maximum anti-shake angle and improve the anti-shake effect.

[0077] In one example, the target parameter includes a moving speed. In step S1200, during the video recording process, when the exposure end time of the current frame image of the video is reached, controlling the target device to move toward the target position according to the target parameter may further include:

[0078] During the video recording process, when the exposure end time of the current frame image of the video is reached, the target device is controlled to move toward a target position according to the moving speed.

[0079] For example, when the exposure of the current frame of the video ends, the drive mechanism can be controlled to move in the direction close to the target position based on the moving speed, so that the lens module moves in the direction close to the target position, and when the exposure of the next frame of the video starts, the drive mechanism is controlled to stop moving in the direction close to the target position. In other words, during the idle time between shooting two frames of images, the drive mechanism is controlled to move in the direction close to the target position to ensure that the center of the drive mechanism, the optical center of the image sensor and the optical axis of the lens module coincide, and the electronic device has the maximum anti-shake angle.

[0080] For another example, when the exposure of the current frame of the video ends, the image sensor can be controlled to move toward the target position based on the moving speed, and when the exposure of the next frame of the video starts, the image sensor can be controlled to stop moving toward the target position. In other words, during the idle time between shooting two frames of images, the image sensor is controlled to move toward the target position to ensure that the center of the drive mechanism, the optical center of the image sensor, and the optical axis of the lens module coincide, and the electronic device has the maximum anti-shake angle.

[0081] In one example, the target parameter also includes a moving ratio. In step S1200, during the video recording process, when the exposure end time of the current frame image of the video is reached, controlling the target device to move to the target position according to the target parameter may further include the following steps S1210 to S1230:

[0082] Step S1210, when the exposure end time of the current frame image of the video is reached, the jitter information of the electronic device is obtained.

[0083] In this example, when the electronic device shakes during the process of shooting an image, the shaking information is generated. The shaking information can be collected by a gyroscope or other sensors. The shaking information can be, for example, the deflection distance of the lens module.

[0084] Step S1220: determining the maximum distance that the target device can move according to the movement ratio and the jitter information.

[0085] In this example, the maximum distance S that the target device can move can be calculated according to the following formula max :

[0086] S max =p*m (1)

[0087] Among them, p represents the movement ratio, and m represents the jitter information.

[0088] Step S1230: Control the target device to move toward the target position according to the moving speed and the maximum distance.

[0089] During the video recording process, when the exposure end time of the current frame image of the video is reached, the target device is controlled to move toward the target position according to the moving speed and the maximum distance.

[0090] For example, at the end of the exposure of the current frame of the video, the driving mechanism can be controlled to move the maximum distance in the direction close to the target position based on the moving speed, so that the lens module moves the maximum distance in the direction close to the target position. And at the start of the exposure of the next frame of the video, or when the distance moved by the target device to the target position reaches the maximum distance, the driving mechanism is controlled to stop moving in the direction close to the target position to ensure that the center of the driving mechanism, the optical center of the image sensor and the optical axis of the lens module coincide, and the electronic device has the maximum anti-shake angle at this time.

[0091] For another example, when the exposure of the current frame image of the video ends, the image sensor can be controlled to move the maximum distance in the direction close to the target position based on the moving speed, and when the exposure start time of the next frame image is reached, or when the distance moved by the target device in the direction close to the target position reaches the maximum distance, the driving mechanism is controlled to stop moving in the direction close to the target position to ensure that the center of the driving mechanism, the optical center of the image sensor and the optical axis of the lens module coincide, and the electronic device has the maximum anti-shake angle.

[0092] During the video recording process, when the exposure of the current frame image of the video ends, the target device is controlled to move toward the target position according to the target parameters, and then enters:

[0093] Step S1300, when the exposure start time of the next frame of image is reached, the next frame of image is captured.

[0094] In this embodiment, since the electronic device has a maximum anti-shake angle when the exposure start time of the first frame of image is reached, the next frame of image can be photographed when the exposure start time of the next frame of image is reached.

[0095] In this embodiment, during the process of capturing the next frame of image, the jitter information of the electronic device may continue to be acquired, and according to the jitter information of the electronic device, the lens module may be controlled to move through the driving mechanism to eliminate the jitter.

[0096] According to this embodiment, during the process of recording a video, the driving mechanism or the image sensor will be controlled to move toward the target position according to the parameter value of the target parameter during the time between the end of exposure of the current frame image of the video and the start of exposure of the next frame image, so as to adjust the position of the driving mechanism or the image sensor, so that when shooting each frame of the image, the electronic device always has a larger anti-shake angle, further reducing the blurring phenomenon of the picture, so that the electronic device has a better anti-shake effect.

[0097] In one embodiment, after executing the above step S1100 to obtain the target parameters, the video recording method of the embodiment of the present disclosure may further include the following step S2100:

[0098] Step S2100: During the video recording process, an action waveform of the target device is displayed on the video recording interface in the form of a floating control.

[0099] The motion waveform is used to represent the moving trajectory of the target device during the video recording process.

[0100] For example, Figure 3As shown in the figure, after selecting the active anti-shake mode, during the video recording process, the action waveform of the driving mechanism is displayed in the video recording interface in the form of a floating window, where the horizontal axis represents time and the vertical axis represents the distance between the driving mechanism and the target position. Figure 3 Curve 1 in FIG. 1 represents the action waveform curve of the driving mechanism in the active anti-shake mode. Figure 3 Curve 2 in the figure represents the jitter curve of the electronic device during video recording. Figure 3 The dashed line in the figure indicates the travel edge of the drive mechanism. Figure 3 It can be seen that when the exposure time of the current frame image arrives, the driving mechanism will be controlled to move to the target position. Figure 4 The figure shows the action waveform of the driving mechanism in the default recording mode.

[0101] According to this embodiment, it is possible to display the action waveform of the target device in real time, making the movement of the target device more intuitive.

[0102] In one embodiment, after executing the above step S2100 to display the action waveform of the target device in the video recording interface in the form of a floating control during the video recording process, the video recording method of the present disclosure further includes the following steps S3100 to S3300:

[0103] Step S3100, receiving a sliding operation on an action waveform diagram of a target device.

[0104] In this embodiment, the user can control the movement of the driving mechanism by a user-defined control. For example, the user can control the movement of the driving mechanism by a finger. Figure 5 Curve 1( Figure 5 The specific curve is not shown) to perform a sliding operation to move the driving mechanism. Figure 6 A sliding operation is performed on the drive mechanism to move the drive mechanism.

[0105] Step S3200, in response to the sliding operation, obtaining the number of pixels involved in the sliding operation and the sliding direction of the sliding operation.

[0106] For example, the user's finger is on Figure 6 After performing a sliding operation, the electronic device can respond to the sliding operation and obtain the number of pixels involved in the sliding operation and the sliding direction of the sliding operation.

[0107] Step S3300: determining a target distance that the target device needs to move according to the number of pixels involved in the sliding operation.

[0108] For example, the electronic device can determine the target distance that the target device needs to move according to the number of pixels involved in the sliding operation.

[0109] According to this embodiment, the moving motor can be customized by the user to meet the user's personalized needs.

[0110] In one embodiment, after executing the above step S1210 and obtaining the jitter information of the electronic device when the exposure end time of the current frame image of the video is reached, the video recording method of the present disclosure further includes the following steps:

[0111] According to the jitter information, the target parameters are adjusted so that when the exposure end time of the next frame image of the video is reached, the target device is controlled to move in a direction close to the target position according to the adjusted target parameters.

[0112] According to this embodiment, after adjusting the target parameters according to the jitter information of the electronic device, when the exposure of the next frame image of the video ends, the target device can be controlled to move in a direction close to the target position according to the adjusted target parameters, so as to ensure that the center of the driving mechanism, the optical center of the image sensor and the optical axis of the lens module coincide with each other. At this time, the electronic device has the maximum anti-shake angle.

[0113] Corresponding to the above embodiment, see Figure 7 The embodiment of the present application further provides a video recording device 700, which is applied to an electronic device, wherein the electronic device includes a driving mechanism and an image sensor, and when the driving mechanism or the image sensor is at a target position, the center of the driving mechanism coincides with the optical center of the image sensor, and the device 700 includes:

[0114] The acquisition module 710 is used to acquire target parameters; wherein the target parameters include moving speed.

[0115] The control module 720 is used to control the target device to move toward the target position according to the target parameters when the exposure of the current frame image of the video ends during the video recording process; wherein the target device includes the driving mechanism or the image sensor.

[0116] The shooting module 730 is used to shoot the next frame image of the video when the exposure start time of the next frame image is reached.

[0117] In one embodiment, the target parameters also include a movement ratio, and the control module 720 is specifically used to: obtain the jitter information of the electronic device when the exposure end time of the current frame image of the video is reached; determine the target distance that the target device can move according to the movement ratio and the jitter information; and control the target device to move in a direction close to the target position according to the moving speed and the target distance.

[0118] In one embodiment, the control module 720 is further used to: control the target device to stop moving in the direction approaching the target position when the exposure start time of the next frame image is reached; or control the target device to stop moving in the direction approaching the target position when the distance moved by the target device in the direction approaching the target position reaches the target distance.

[0119] In one embodiment, the device 700 further includes a display module (not shown in the figure).

[0120] The display module is used to display the action waveform of the target device on the recording interface of the video in the form of a floating control during the recording of the video.

[0121] The motion waveform is used to represent the moving trajectory of the target device during the recording of the video.

[0122] In one embodiment, the acquisition module 710 is further used to receive a sliding operation on the action waveform diagram of the target device; and, in response to the sliding operation, to acquire the number of pixels involved in the sliding operation and the sliding direction of the sliding operation.
