在本公开的一些实施例所提供的技术方案中,处理平台基于抖动前后图像中目标对象坐标位置的变化,计算镜头偏移量,并基于该镜头偏移量控制镜头移动。一方面,本公开通过基于图像内容的光学防抖方式来进行拍摄控制,可以实现针对目标对象的图像跟踪,控制目标对象尽可能稳定在图像中,并且光学防抖可以延长目标对象在感光元件上的曝光时间,使得拍摄出的目标对象更清晰,尤其对于拍摄处于运动状态下的目标对象,可以有效避免图像模糊的情况发生;另一方面,本公开方案中利用目标对象在图像中的位置计算镜头偏移量的过程被配置在处理平台上执行,相比于一些将算法部署在驱动芯片上的方案,本公开方案可以减少处理平台与驱动芯片之间的通信交互,进而可以减少二者之间配置的传输线的数量,节约了成本。另外,对于终端设备的生产厂商而言,由于算法主要部署在处理平台而非摄像头模组,因此,可以降低摄像头模组的采购价格,进一步节约了成本。In the technical solutions provided by some embodiments of the present disclosure, the processing platform calculates the lens offset based on the change in the coordinate position of the target object in the image before and after the shaking, and controls the movement of the lens based on the lens offset. On the one hand, the present disclosure performs shooting control by optical image stabilization based on the image content, which can realize image tracking for the target object and control the target object to be as stable as possible in the image, and the optical image stabilization can extend the exposure time of the target object on the photosensitive element, so that the captured target object is clearer, especially for shooting the target object in motion, which can effectively avoid the occurrence of image blur; on the other hand, the process of calculating the lens offset using the position of the target object in the image in the present disclosure is configured to be executed on the processing platform. Compared with some solutions that deploy the algorithm on the driver chip, the present disclosure can reduce the communication interaction between the processing platform and the driver chip, and then reduce the number of transmission lines configured between the two, saving costs. In addition, for the manufacturers of terminal equipment, since the algorithm is mainly deployed on the processing platform rather than the camera module, the purchase price of the camera module can be reduced, further saving costs.

本公开实施方式的拍摄控制系统可以配置于终端设备中,终端设备为具备拍摄功能的任意电子设备,包括但不限于智能手机、平板电脑、智能手表、摄影机、移动监控设备等。The shooting control system of the embodiment of the present disclosure can be configured in a terminal device, which is any electronic device with a shooting function, including but not limited to smart phones, tablet computers, smart watches, cameras, mobile monitoring devices, etc.

图1示出了本公开实施方式的拍摄控制系统的系统架构的示意图。FIG. 1 is a schematic diagram showing a system architecture of a shooting control system according to an embodiment of the present disclosure.

参考图1,本公开实施方式的拍摄控制系统可以包括处理平台11和摄像头模组12。1 , the shooting control system according to the embodiment of the present disclosure may include a processing platform 11 and a camera module 12 .

处理平台11可以是终端设备的芯片平台,可以是CPU(Central Processing Unit,中央处理器)。另外,处理平台11还可以是终端设备的SOC(System on Chip,系统级芯片)、MCU(Microcontroller Unit,微控制单元)、DSP(Digital Signal Processor,数字信号处理器)等。The processing platform 11 may be a chip platform of the terminal device, and may be a CPU (Central Processing Unit). In addition, the processing platform 11 may also be a SOC (System on Chip), an MCU (Microcontroller Unit), a DSP (Digital Signal Processor), etc. of the terminal device.

摄像头模组12可以至少包括驱动芯片121、马达122和镜头123。虽然未示出,但可以理解的是,摄像头模组还可以包括感光元件(sensor)等其他元件。The camera module 12 may include at least a driving chip 121, a motor 122 and a lens 123. Although not shown, it is understandable that the camera module may also include other components such as a photosensitive element (sensor).

驱动芯片121可以是用于驱动马达等负载的芯片。驱动芯片121可以是单通道驱动芯片或多通道驱动芯片,本公开对此不做限制。单通道驱动芯片指的是只有一路电信号传递至马达的驱动芯片,多通道驱动芯片指的是可以同时输出多路电信号传递至马达的驱动芯片。可以理解的是,单通道驱动芯片不限于只有一个输出端,也可以有多个输出端,而输出至马达的输出端可以只有一个。本公开实施方式所说的电信号可以是电流信号、电压信号或其他类型的电信号,本公开对此不做限制。The driver chip 121 may be a chip for driving loads such as motors. The driver chip 121 may be a single-channel driver chip or a multi-channel driver chip, which is not limited in the present disclosure. A single-channel driver chip refers to a driver chip that has only one electrical signal transmitted to the motor, and a multi-channel driver chip refers to a driver chip that can simultaneously output multiple electrical signals to the motor. It is understandable that a single-channel driver chip is not limited to having only one output terminal, but may also have multiple output terminals, and there may be only one output terminal output to the motor. The electrical signal referred to in the embodiments of the present disclosure may be a current signal, a voltage signal, or other types of electrical signals, which is not limited in the present disclosure.

马达122可以是音圈马达(Voice Coil Motor,VCM),是用于将电能转换为机械能以驱动镜头123移动的装置。The motor 122 may be a voice coil motor (VCM), which is a device for converting electrical energy into mechanical energy to drive the lens 123 to move.

镜头123可以是各种类型的镜头,例如定焦镜头、变焦镜头、广角镜头、长焦镜头、微距镜头等。The lens 123 may be various types of lenses, such as a fixed focus lens, a zoom lens, a wide angle lens, a telephoto lens, a macro lens, etc.

在实现本公开实施方式的拍摄控制过程中,首先,处理平台11可以获取摄像头模组12拍摄的第一图像,并确定第一图像中目标对象的坐标位置;接下来,当摄像头模组12出现抖动时,处理平台11可以获取摄像头模组12拍摄的第二图像,并确定第二图像中目标对象的坐标位置;随后,处理平台11可以根据第一图像中目标对象的坐标位置和第二图像中目标对象的坐标位置,计算镜头偏移量;然后,处理平台11可以将镜头偏移量发送给摄像头模组12中的驱动芯片121。其中,处理平台11与驱动芯片121可以通过IIC(Inter-Integrated Circuit,集成电路总线)连接。In the process of implementing the shooting control of the embodiment of the present disclosure, first, the processing platform 11 can obtain the first image taken by the camera module 12 and determine the coordinate position of the target object in the first image; next, when the camera module 12 shakes, the processing platform 11 can obtain the second image taken by the camera module 12 and determine the coordinate position of the target object in the second image; then, the processing platform 11 can calculate the lens offset according to the coordinate position of the target object in the first image and the coordinate position of the target object in the second image; then, the processing platform 11 can send the lens offset to the driver chip 121 in the camera module 12. Among them, the processing platform 11 and the driver chip 121 can be connected through IIC (Inter-Integrated Circuit, integrated circuit bus).

驱动芯片121在接收到处理平台11发送的镜头偏移量之后,可以根据镜头偏移量向马达122输出电信号。马达122可以根据电信号控制镜头123移动。其中,电信号中可以携带方向标识和信号强度,根据方向标识可以确定出推动镜头123移动的方向,根据信号强度可以确定出推动镜头123移动的距离。After receiving the lens offset sent by the processing platform 11, the driving chip 121 can output an electrical signal to the motor 122 according to the lens offset. The motor 122 can control the movement of the lens 123 according to the electrical signal. The electrical signal can carry a direction identifier and a signal strength. The direction in which the lens 123 is pushed to move can be determined according to the direction identifier, and the distance in which the lens 123 is pushed to move can be determined according to the signal strength.

可以理解的是,控制镜头123移动的方向与摄像头模组12抖动的方向相反,再结合与抖动距离对应的镜头移动距离,可以消除因抖动造成的镜头偏移。It can be understood that by controlling the movement direction of the lens 123 to be opposite to the shaking direction of the camera module 12, combined with the lens movement distance corresponding to the shaking distance, the lens offset caused by the shaking can be eliminated.

本公开实施方式对目标对象的类型不做限制,可以是用户根据图像内容选择出的对象,也可以是预定指定的对象,例如,人脸、足球、月亮等。在下面的示例性说明中,可以将目标对象中心点的坐标位置作为目标对象的坐标位置。然而,可以理解的是,在目标对象被限定在矩形框的实施例中,还可以利用矩形框的长度和宽度以及矩形框上预定一点(如顶点、中心点等)的坐标来表征目标对象的坐标位置。The disclosed embodiments do not limit the type of the target object, which may be an object selected by the user according to the image content, or a predetermined object, such as a face, a football, a moon, etc. In the following exemplary description, the coordinate position of the center point of the target object may be used as the coordinate position of the target object. However, it is to be understood that in an embodiment where the target object is confined within a rectangular frame, the length and width of the rectangular frame and the coordinates of a predetermined point (such as a vertex, a center point, etc.) on the rectangular frame may also be used to characterize the coordinate position of the target object.

下面对处理平台11确定第一图像中目标对象的坐标位置的过程进行说明。The following is an explanation of the process by which the processing platform 11 determines the coordinate position of the target object in the first image.

根据本公开的一些实施例,在第一图像呈现在终端设备的触控屏上的情况下,处理平台11可以响应对象选取操作,确定出目标对象,进而确定目标对象在第一图像中的坐标位置。According to some embodiments of the present disclosure, when the first image is presented on the touch screen of the terminal device, the processing platform 11 can respond to the object selection operation, determine the target object, and then determine the coordinate position of the target object in the first image.

例如,用户可以通过触控屏点击第一图像上一对象,处理平台11响应用户的该点击操作,确定出目标对象。如用户点击了第一图像中的足球,则可以将足球确定为目标对象。接下来,可以将该足球的球心的坐标作为本公开所说的目标对象在第一图像中的坐标位置。For example, the user can click on an object on the first image through the touch screen, and the processing platform 11 responds to the user's click operation and determines the target object. For example, if the user clicks on a football in the first image, the football can be determined as the target object. Next, the coordinates of the center of the football can be used as the coordinate position of the target object in the first image mentioned in the present disclosure.

根据本公开的另一些实施例,处理平台11在获取到第一图像后,可以对第一图像进行图像识别,并计算图像识别的结果与预先定义的目标对象的相似度,在相似度大于相似度阈值的情况下,处理平台11可以将图像识别的结果确定为目标对象,进而确定出目标对象在第一图像中的坐标位置。其中,本公开对相似度阈值的具体取值不做限制。According to other embodiments of the present disclosure, after acquiring the first image, the processing platform 11 may perform image recognition on the first image, and calculate the similarity between the image recognition result and the predefined target object. When the similarity is greater than the similarity threshold, the processing platform 11 may determine the image recognition result as the target object, and further determine the coordinate position of the target object in the first image. The present disclosure does not limit the specific value of the similarity threshold.

具体的,处理平台11可以依据预先配置的特征提取算法,从第一图像中提取特征点的集合,并将集合中的特征点与预先配置的目标对象的特征点进行比较,确定出二者的相似度,再利用该相似度确定出目标对象,进而确定出目标对象在第一图像中的坐标位置。Specifically, the processing platform 11 can extract a set of feature points from the first image based on a preconfigured feature extraction algorithm, and compare the feature points in the set with the preconfigured feature points of the target object to determine the similarity between the two, and then use the similarity to determine the target object, and then determine the coordinate position of the target object in the first image.

可以理解的是,在未从图像中确定出目标图像的情况下,本公开实施方式的拍摄控制方案停止,处理平台11可以不断执行目标对象的确认过程,直至确定出目标对象以及目标对象在图像中的坐标位置后,继续执行本公开实施方式的拍摄控制方案。It can be understood that when the target image is not determined from the image, the shooting control scheme of the embodiment of the present disclosure stops, and the processing platform 11 can continuously execute the target object confirmation process until the target object and the coordinate position of the target object in the image are determined, and then continue to execute the shooting control scheme of the embodiment of the present disclosure.

另外,处理平台11确定第二图像中目标对象的坐标位置的过程与上述内容类似,不再赘述。In addition, the process of the processing platform 11 determining the coordinate position of the target object in the second image is similar to the above content and will not be repeated herein.

下面对处理平台11确定摄像头模组12抖动的过程进行说明。The following is an explanation of the process by which the processing platform 11 determines whether the camera module 12 is shaking.

根据本公开的一些实施例,处理平台11可以利用陀螺仪传感器感测的数据,确定摄像头模组12是否出现抖动。According to some embodiments of the present disclosure, the processing platform 11 may use data sensed by the gyroscope sensor to determine whether the camera module 12 is shaking.

参考图2,本公开实施方式的拍摄控制系统还可以包括陀螺仪传感器21。陀螺仪传感器21是一种高速回转体的动量矩敏感壳体相对惯性空间绕正交于自转轴的角运动检测装置,可以是压电陀螺仪传感器、机械陀螺仪传感器、光纤陀螺仪传感器、激光陀螺仪传感器中的任一种。另外,陀螺仪传感器21与处理平台11可以通过SPI(Serial PeripheralInterface,串行外设接口)连接。Referring to FIG. 2 , the shooting control system of the disclosed embodiment may further include a gyro sensor 21. The gyro sensor 21 is a device for detecting the angular motion of a high-speed rotating body relative to the inertial space around the axis of rotation orthogonal to the momentum sensitive shell, and may be any one of a piezoelectric gyro sensor, a mechanical gyro sensor, a fiber optic gyro sensor, and a laser gyro sensor. In addition, the gyro sensor 21 and the processing platform 11 may be connected via a SPI (Serial Peripheral Interface).

陀螺仪传感器21可以检测摄像头模组12在一个或多个方向上的角速度,从而可以根据检测到的角速度判断摄像头模组12是否出现抖动。The gyro sensor 21 can detect the angular velocity of the camera module 12 in one or more directions, so as to determine whether the camera module 12 is shaking according to the detected angular velocity.

具体的,处理平台11可以获取陀螺仪传感器21感测到的角速度,并将感测到的角速度与角速度阈值进行比较,在感测到的角速度大于角速度阈值的情况下,处理平台11确定出摄像头模组12出现抖动。在感测到的角速度小于等于角速度阈值的情况下,处理平台11确定出摄像头模组12未出现抖动。其中,本公开对角速度阈值的具体取值不做限制。Specifically, the processing platform 11 can obtain the angular velocity sensed by the gyroscope sensor 21, and compare the sensed angular velocity with the angular velocity threshold. When the sensed angular velocity is greater than the angular velocity threshold, the processing platform 11 determines that the camera module 12 is shaking. When the sensed angular velocity is less than or equal to the angular velocity threshold, the processing platform 11 determines that the camera module 12 is not shaking. The present disclosure does not limit the specific value of the angular velocity threshold.

根据本公开的另一些实施例,针对处理平台11判断摄像头模组12是否出现抖动的过程,在连续拍摄的场景中,可以根据拍摄出图像确定摄像头模组12是否出现抖动。According to other embodiments of the present disclosure, with respect to the process in which the processing platform 11 determines whether the camera module 12 is shaking, in a continuous shooting scenario, it can be determined based on the captured images whether the camera module 12 is shaking.

具体的,可以通过拍摄出的图像确定场景中的固定物体,如桌子、树木、建筑物等,然后,判断固定物体在相邻帧中分别的位置,确定摄像头模组12是否出现抖动。例如,相邻帧中固定物体的位置变化在预定范围内,则表明摄像头模组12出现抖动。Specifically, the fixed objects in the scene, such as tables, trees, buildings, etc., can be determined through the captured images, and then the positions of the fixed objects in adjacent frames are determined to determine whether the camera module 12 is shaking. For example, if the position change of the fixed objects in adjacent frames is within a predetermined range, it indicates that the camera module 12 is shaking.

下面对处理平台11计算镜头偏移量的过程进行说明。The process of calculating the lens offset by the processing platform 11 is described below.

在摄像头模组12出现抖动的情况下,目标对象在摄像头模组12中的感光元件上成像的位置会发生变化,也就是说,目标对象在第一图像和第二图像中的坐标位置会发生变化。When the camera module 12 shakes, the position of the image of the target object on the photosensitive element in the camera module 12 will change, that is, the coordinate position of the target object in the first image and the second image will change.

首先,处理平台11可以根据第一图像中目标对象的坐标位置和第二图像中目标对象的坐标位置计算目标对象的像素偏移量。First, the processing platform 11 may calculate the pixel offset of the target object according to the coordinate position of the target object in the first image and the coordinate position of the target object in the second image.

如果将第一图像中目标对象的坐标位置记为src_local(x,y),将第二图像中目标对象的坐标位置记为rotate_local(x,y),将像素偏移量记为delta(x,y),则可以利用下式计算出像素偏移量delta(x,y):If the coordinate position of the target object in the first image is recorded as src_local(x,y), the coordinate position of the target object in the second image is recorded as rotate_local(x,y), and the pixel offset is recorded as delta(x,y), then the pixel offset delta(x,y) can be calculated using the following formula:

delta(x,y)=rotate_local(x,y)-src_local(x,y)delta(x,y)=rotate_local(x,y)-src_local(x,y)

接下来,处理平台11可以利用目标对象的像素偏移量计算镜头偏移量。可以理解的是,镜头偏移量包含镜头移动补偿的方向和程度。Next, the processing platform 11 may calculate the lens offset using the pixel offset of the target object. It is understandable that the lens offset includes the direction and degree of lens movement compensation.

具体的,处理平台11可以将目标对象的像素偏移量与增益阈值相乘,以得到镜头偏移量。Specifically, the processing platform 11 may multiply the pixel offset of the target object by the gain threshold to obtain the lens offset.

如果将镜头偏移量记为delta_hall(hall_x,hall_y),将增益阈值记为pixelgain(x,y),则可以利用下式计算出镜头偏移量delta_hall(hall_x,hall_y):If the lens offset is recorded as delta_hall(hall_x, hall_y) and the gain threshold is recorded as pixelgain(x, y), the lens offset delta_hall(hall_x, hall_y) can be calculated using the following formula:

delta_hall(hall_x,hall_y)=delta(x,y)*pixelgain(x,y)delta_hall(hall_x,hall_y)=delta(x,y)*pixelgain(x,y)

通过上式,可以分别计算出x方向上的镜头偏移量和y方向上的镜头偏移量。By using the above formula, the lens offset in the x direction and the lens offset in the y direction can be calculated respectively.

应当理解的是,像素偏移量的单位为像素(pixel),镜头偏移量的单位为code。It should be understood that the unit of the pixel offset is pixel (pixel), and the unit of the lens offset is code.

需要说明的是,马达122可以分别在x方向和y方向上控制镜头123移动。在实际场景中,镜头123的行程范围受硬件限制。图3示出了本公开实施例的镜头行程的示意图。镜头默认配置在中心位置,在驱动镜头移动时,线性行程仅占全行程的一部分,其余部分为非线性行程。It should be noted that the motor 122 can control the movement of the lens 123 in the x-direction and the y-direction respectively. In actual scenarios, the travel range of the lens 123 is limited by hardware. FIG3 shows a schematic diagram of the lens travel of an embodiment of the present disclosure. The lens is configured at the center position by default. When the lens is driven to move, the linear travel only accounts for a part of the full travel, and the rest is a nonlinear travel.

上面以分析第一图像和第二图像为例对本公开示例性拍摄控制方案进行了说明,然而,应当理解的是,在连续采集图像的场景中,可以不断执行上述拍摄控制过程。控制镜头123移动的频率通常较高,在不断进行逐行地曝光及成像的过程中,不断控制镜头123移动,以提高拍摄效果。The above exemplary shooting control scheme of the present disclosure is described by taking the analysis of the first image and the second image as an example. However, it should be understood that in the scenario of continuously collecting images, the above shooting control process can be continuously performed. The frequency of controlling the movement of the lens 123 is usually high. In the process of continuously performing line-by-line exposure and imaging, the movement of the lens 123 is continuously controlled to improve the shooting effect.

进一步的,本公开实施方式中还提供了一种拍摄控制方法。该拍摄控制方法可以通过终端设备实现,具体的,可以由上述处理平台11执行拍摄控制方法的各个步骤。在这种情况下,下述拍摄控制装置可以配置在处理平台11中。Furthermore, a shooting control method is also provided in the embodiment of the present disclosure. The shooting control method can be implemented by a terminal device, and specifically, each step of the shooting control method can be executed by the above-mentioned processing platform 11. In this case, the following shooting control device can be configured in the processing platform 11.

图4示意性示出了本公开的示例性实施方式的拍摄控制方法的流程图。参考图4,该拍摄控制方法可以包括以下步骤:FIG4 schematically shows a flow chart of a shooting control method according to an exemplary embodiment of the present disclosure. Referring to FIG4 , the shooting control method may include the following steps:

S42.获取摄像头模组拍摄的第一图像,确定第一图像中目标对象的坐标位置。S42. Acquire a first image captured by the camera module, and determine the coordinate position of the target object in the first image.

本公开实施方式对目标对象的类型不做限制,可以是用户根据图像内容选择出的对象,也可以是预定指定的对象,例如,人脸、足球、月亮等。在下面的示例性说明中,可以将目标对象中心点的坐标位置作为目标对象的坐标位置。然而,可以理解的是,在目标对象被限定在矩形框的实施例中,还可以利用矩形框的长度和宽度以及矩形框上预定一点(如顶点、中心点等)的坐标来表征目标对象的坐标位置。The disclosed embodiments do not limit the type of the target object, which may be an object selected by the user according to the image content, or a predetermined object, such as a face, a football, a moon, etc. In the following exemplary description, the coordinate position of the center point of the target object may be used as the coordinate position of the target object. However, it is to be understood that in an embodiment where the target object is confined within a rectangular frame, the length and width of the rectangular frame and the coordinates of a predetermined point (such as a vertex, a center point, etc.) on the rectangular frame may also be used to characterize the coordinate position of the target object.

根据本公开的一些实施例,在第一图像呈现在终端设备的触控屏上的情况下,处理平台可以响应对象选取操作,确定出目标对象,进而确定目标对象在第一图像中的坐标位置。According to some embodiments of the present disclosure, when the first image is presented on the touch screen of the terminal device, the processing platform can respond to the object selection operation, determine the target object, and then determine the coordinate position of the target object in the first image.

例如,用户可以通过触控屏点击第一图像上一对象,处理平台响应用户的点击操作,确定出目标对象。如用户点击了第一图像中的足球,则可以将足球确定为目标对象。接下来,可以将该足球的球心的坐标作为本公开所说的目标对象在第一图像中的坐标位置。For example, a user can click on an object on the first image through the touch screen, and the processing platform responds to the user's click operation to determine the target object. For example, if the user clicks on a football in the first image, the football can be determined as the target object. Next, the coordinates of the center of the football can be used as the coordinate position of the target object in the first image as described in the present disclosure.

根据本公开的另一些实施例,处理平台在获取到第一图像后,可以对第一图像进行图像识别,并计算图像识别的结果与预先定义的目标对象的相似度,在相似度大于相似度阈值的情况下,处理平台可以将图像识别的结果确定为目标对象,进而确定出目标对象在第一图像中的坐标位置。其中,本公开对相似度阈值的具体取值不做限制。According to other embodiments of the present disclosure, after acquiring the first image, the processing platform may perform image recognition on the first image, and calculate the similarity between the image recognition result and the predefined target object. When the similarity is greater than a similarity threshold, the processing platform may determine the image recognition result as the target object, and further determine the coordinate position of the target object in the first image. The present disclosure does not limit the specific value of the similarity threshold.

具体的,处理平台可以依据预先配置的特征提取算法,从第一图像中提取特征点的集合,并将集合中的特征点与预先配置的目标对象的特征点进行比较,确定出二者的相似度,再利用该相似度确定出目标对象,进而确定出目标对象在第一图像中的坐标位置。Specifically, the processing platform can extract a set of feature points from the first image based on a preconfigured feature extraction algorithm, and compare the feature points in the set with the preconfigured feature points of the target object to determine the similarity between the two, and then use the similarity to determine the target object, and then determine the coordinate position of the target object in the first image.

可以理解的是,第一图像是包含目标对象的图像。在拍摄出的图像中未包括目标图像的情况下,本公开实施方式的拍摄控制方案停止,处理平台可以不断针对拍摄出的图像执行目标对象的确认过程,直至确定出目标对象以及目标对象在图像中的坐标位置后,继续执行本公开实施方式的拍摄控制方案。It is understandable that the first image is an image containing the target object. In the case that the captured image does not include the target image, the shooting control scheme of the embodiment of the present disclosure stops, and the processing platform can continuously perform the target object confirmation process for the captured image until the target object and the coordinate position of the target object in the image are determined, and then continue to execute the shooting control scheme of the embodiment of the present disclosure.

S44.当摄像头模组出现抖动时,获取摄像头模组拍摄的第二图像,确定第二图像中目标对象的坐标位置。S44. When the camera module shakes, obtain a second image captured by the camera module and determine the coordinate position of the target object in the second image.

根据本公开的一些实施例,处理平台可以利用陀螺仪传感器感测的数据,确定摄像头模组是否出现抖动。According to some embodiments of the present disclosure, the processing platform may use data sensed by the gyroscope sensor to determine whether the camera module is shaking.

陀螺仪传感器可以检测摄像头模组在一个或多个方向上的角速度,从而可以根据检测到的角速度判断摄像头模组是否出现抖动。The gyroscope sensor can detect the angular velocity of the camera module in one or more directions, so that it can be determined whether the camera module is shaking based on the detected angular velocity.

具体的,处理平台可以获取陀螺仪传感器感测到的角速度,并将感测到的角速度与角速度阈值进行比较,在感测到的角速度大于角速度阈值的情况下,处理平台确定出摄像头模组出现抖动。在感测到的角速度小于等于角速度阈值的情况下,处理平台确定出摄像头模组未出现抖动。其中,本公开对角速度阈值的具体取值不做限制。Specifically, the processing platform can obtain the angular velocity sensed by the gyroscope sensor, and compare the sensed angular velocity with the angular velocity threshold. When the sensed angular velocity is greater than the angular velocity threshold, the processing platform determines that the camera module is shaking. When the sensed angular velocity is less than or equal to the angular velocity threshold, the processing platform determines that the camera module is not shaking. The present disclosure does not limit the specific value of the angular velocity threshold.

根据本公开的另一些实施例,针对处理平台判断摄像头模组是否出现抖动的过程,在连续拍摄的场景中,可以根据拍摄出图像确定摄像头模组是否出现抖动。According to other embodiments of the present disclosure, with respect to the process of the processing platform determining whether the camera module is shaking, in a continuous shooting scenario, it can be determined whether the camera module is shaking based on the captured images.

具体的,可以通过拍摄出的图像确定场景中的固定物体,如桌子、树木、建筑物等,然后,判断固定物体在相邻帧中分别的位置,确定摄像头模组是否出现抖动。例如,相邻帧中固定物体的位置变化在预定范围内,则表明摄像头模组出现抖动。Specifically, the fixed objects in the scene, such as tables, trees, buildings, etc., can be determined through the captured images, and then the positions of the fixed objects in adjacent frames can be determined to determine whether the camera module is shaking. For example, if the position change of the fixed objects in adjacent frames is within a predetermined range, it indicates that the camera module is shaking.

确定第二图像中目标对象的坐标位置与步骤S42中确定第一图像中目标对象的坐标位置的过程类似,不再赘述。The process of determining the coordinate position of the target object in the second image is similar to the process of determining the coordinate position of the target object in the first image in step S42, and will not be described in detail.

S46.根据第一图像中目标对象的坐标位置和第二图像中目标对象的坐标位置,计算镜头偏移量。S46. Calculate the lens offset according to the coordinate position of the target object in the first image and the coordinate position of the target object in the second image.

在摄像头模组出现抖动的情况下,目标对象在摄像头模组中的感光元件上成像的位置会发生变化,也就是说,目标对象在第一图像和第二图像中的坐标位置会发生变化。When the camera module shakes, the position of the image of the target object on the photosensitive element in the camera module will change, that is, the coordinate position of the target object in the first image and the second image will change.

首先,处理平台可以根据第一图像中目标对象的坐标位置和第二图像中目标对象的坐标位置计算目标对象的像素偏移量。First, the processing platform may calculate a pixel offset of the target object according to the coordinate position of the target object in the first image and the coordinate position of the target object in the second image.

如果将第一图像中目标对象的坐标位置记为src_local(x,y),将第二图像中目标对象的坐标位置记为rotate_local(x,y),将像素偏移量记为delta(x,y),则可以利用下式计算出像素偏移量delta(x,y):If the coordinate position of the target object in the first image is recorded as src_local(x,y), the coordinate position of the target object in the second image is recorded as rotate_local(x,y), and the pixel offset is recorded as delta(x,y), then the pixel offset delta(x,y) can be calculated using the following formula:

delta(x,y)=rotate_local(x,y)-src_local(x,y)delta(x,y)=rotate_local(x,y)-src_local(x,y)

接下来,处理平台可以利用目标对象的像素偏移量计算镜头偏移量。可以理解的是,镜头偏移量包含镜头移动补偿的方向和程度。Next, the processing platform can calculate the lens offset using the pixel offset of the target object. It can be understood that the lens offset includes the direction and degree of lens movement compensation.

具体的,处理平台可以将目标对象的像素偏移量与增益阈值相乘,以得到镜头偏移量。Specifically, the processing platform may multiply the pixel offset of the target object by the gain threshold to obtain the lens offset.

如果将镜头偏移量记为delta_hall(hall_x,hall_y),将增益阈值记为pixelgain(x,y),则可以利用下式计算出镜头偏移量delta_hall(hall_x,hall_y):If the lens offset is recorded as delta_hall(hall_x, hall_y) and the gain threshold is recorded as pixelgain(x, y), the lens offset delta_hall(hall_x, hall_y) can be calculated using the following formula:

delta_hall(hall_x,hall_y)=delta(x,y)*pixelgain(x,y)delta_hall(hall_x,hall_y)=delta(x,y)*pixelgain(x,y)

通过上式,可以分别计算出x方向上的镜头偏移量和y方向上的镜头偏移量。By using the above formula, the lens offset in the x direction and the lens offset in the y direction can be calculated respectively.

应当理解的是,像素偏移量的单位为像素(pixel),镜头偏移量的单位为code。It should be understood that the unit of the pixel offset is pixel (pixel), and the unit of the lens offset is code.

S48.将镜头偏移量发送给驱动芯片,以便驱动芯片根据镜头偏移量向马达输出电信号,由马达根据电信号控制镜头移动。S48. Send the lens offset to the driving chip so that the driving chip outputs an electrical signal to the motor according to the lens offset, and the motor controls the movement of the lens according to the electrical signal.

在本公开的示例性实施方式中,驱动芯片、马达和镜头配置于摄像头模组中。In an exemplary embodiment of the present disclosure, a driving chip, a motor, and a lens are configured in a camera module.

下面以一个实施例对控制镜头移动的过程进行说明。The process of controlling the movement of the lens is described below with reference to an embodiment.

以镜头的初始位置的中心为原点,镜头所在的平面建立xy坐标系。当镜头当前的坐标位置为(-1,+5)时,如果处理平台计算出的镜头偏移量中x轴的偏移量为+2,y轴的偏移量-3,则驱动芯片根据镜头偏移量输出电信号,控制马达在x轴的正方向上移动2个单位长度,在y轴的负方向上移动3个单位长度。The center of the initial position of the lens is taken as the origin, and the plane where the lens is located establishes an xy coordinate system. When the current coordinate position of the lens is (-1, +5), if the x-axis offset of the lens offset calculated by the processing platform is +2 and the y-axis offset is -3, the driver chip outputs an electrical signal according to the lens offset to control the motor to move 2 unit lengths in the positive direction of the x-axis and 3 unit lengths in the negative direction of the y-axis.

另外,镜头偏移量也可以通过矢量的形式表示,即镜头偏移量可以包含镜头的偏移方向和偏移量,本公开对此不做限制。In addition, the lens offset may also be expressed in the form of a vector, that is, the lens offset may include the offset direction and offset of the lens, which is not limited in the present disclosure.

图5示出了本公开实施例的一次拍摄控制过程的示意图。FIG. 5 is a schematic diagram showing a one-shot control process according to an embodiment of the present disclosure.

如图5所示,摄像头模组静止状态时,目标对象可以在感光元件上成像,生成第一图像。As shown in FIG. 5 , when the camera module is in a stationary state, the target object can be imaged on the photosensitive element to generate a first image.

在镜头和感光元件作为一个整体旋转时,目标对象成像位置相比于静止状态发生了偏移,此时,生成第二图像。When the lens and the photosensitive element rotate as a whole, the imaging position of the target object is offset compared to the static state, and at this time, a second image is generated.

在基于本公开实施方式的拍摄控制方案后,可以利用目标对象坐标位置的变化,计算出镜头偏移量,进而推动镜头。由此,目标对象在感光元件上的成像被补偿到静止状态时的中间位置。After the shooting control scheme based on the embodiment of the present disclosure, the lens offset can be calculated by using the change of the coordinate position of the target object, and then the lens is pushed, so that the image of the target object on the photosensitive element is compensated to the middle position when it is in a static state.

上面以一次控制过程对本公开示例性拍摄控制方案进行了说明,然而,应当理解的是,在连续采集图像的场景中,可以不断执行上述拍摄控制过程。控制镜头移动的频率通常较高,在不断进行逐行地曝光及成像的过程中,不断控制镜头移动,以提高拍摄效果。The above describes the exemplary shooting control scheme of the present disclosure using one control process. However, it should be understood that in a scene where images are continuously collected, the above shooting control process can be continuously performed. The frequency of controlling the movement of the lens is usually high. In the process of continuous exposure and imaging line by line, the movement of the lens is continuously controlled to improve the shooting effect.

应当注意,尽管在附图中以特定顺序描述了本公开中方法的各个步骤,但是,这并非要求或者暗示必须按照该特定顺序来执行这些步骤,或是必须执行全部所示的步骤才能实现期望的结果。附加的或备选的,可以省略某些步骤,将多个步骤合并为一个步骤执行,以及/或者将一个步骤分解为多个步骤执行等。It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and/or one step may be decomposed into multiple steps, etc.

进一步的,本公开实施方式中还提供了一种拍摄控制装置。Furthermore, a shooting control device is also provided in an embodiment of the present disclosure.

The driver chip, the motor and the lens are configured in the camera module.

由于本公开实施方式的拍摄控制装置的各个功能模块与上述系统及方法实施方式中相同,因此在此不再赘述。Since the functional modules of the shooting control device in the embodiment of the present disclosure are the same as those in the above-mentioned system and method embodiments, they will not be described in detail here.
