参照图1，其示出了本申请实施例提供的一种拍摄方法的步骤示意图，方法包括：Referring to FIG. 1 , it shows a schematic diagram of steps of a photographing method provided by an embodiment of the present application. The method includes:
步骤101、显示由摄像头采集的预览图像。Step 101: Display the preview image collected by the camera.
在本申请实施例中，进一步参照图2，其示出了本申请实施例提供的一种拍摄方法的应用场景示意图，拍摄方法可以应用于包括前置摄像头11和后置摄像头12的电子设备10，拍摄者20可以手持电子设备10，通过前置摄像头11或后置摄像头12对拍摄场景30中的对象进行拍摄，在拍摄过程中，难免会出现因拍摄者手抖或所处环境影响而导致的电子设备10抖动的情况，导致拍摄出的画面显示的对象模糊、成像效果较差。In the embodiment of the present application, referring further to FIG. 2 , it shows a schematic diagram of an application scenario of a shooting method provided by the embodiment of the present application. The shooting method can be applied to the
在实际应用中，拍摄者20在拍摄时所关注的对象，一般为较重要的目标对象，拍摄者20对该目标对象在画面中的成像效果通常具有较高要求。In practical applications, the object that the
因此，可选地，本申请实施例可以基于电子设备10的前置摄像头11，确定拍摄者20的视线21的视线方向，并通过前置摄像头11或后置摄像头12对拍摄场景30进行拍摄，将采集到的画面作为预览图像显示在电子设备的显示屏上，从而根据视线方向所指向的显示屏中的对象，确定用户当前所关注的目标对象。Therefore, optionally, the embodiment of the present application may determine the line of sight direction of the line of
具体的，判断拍摄者的视线的视线方向可以包括：首先通过前置摄像头采集拍摄者的眼睛的瞳孔特征，并实时检测该瞳孔特征相对于前置摄像头的镜头之间的方位关系，由该方位关系得到眼睛的视线，其中，视线是指眼睛看东西时，瞳孔和物体之间的假想直线。Specifically, judging the line of sight direction of the photographer's line of sight may include: first collecting the pupil feature of the photographer's eye through the front camera, and detecting the azimuth relationship between the pupil feature relative to the lens of the front camera in real time, and using the azimuth The relationship gets the line of sight of the eye, where the line of sight refers to the imaginary straight line between the pupil and the object when the eye is looking.
步骤102、确定用户在所述预览图像中的注视对象。Step 102: Determine the object of the user's gaze in the preview image.
在本申请实施例中，电子设备的前置摄像头可以确定拍摄者的视线的视线方向，电子设备的显示屏则可以将前置摄像头或后置摄像头采集到的画面进行显示，判断拍摄者是否在看一个对象，可以为判断该视线在显示屏上形成的焦点是否长期处于该对象的区域中。视线在显示屏上形成的焦点可以为视线在视线方向上的延伸线与显示屏表面之间的交点。因此，当拍摄者的视线对应在显示屏上的焦点处于目标对象区域中较长时间时，可以将目标对象确定为关注的注视对象。当然，也可采用其他方法来确定注视对象，本申请实施例对此不作具体限定。In the embodiment of the present application, the front camera of the electronic device can determine the line of sight of the photographer, and the display screen of the electronic device can display the picture captured by the front camera or the rear camera to determine whether the photographer is in the Looking at an object, it can be determined whether the focus formed by the sight line on the display screen is in the area of the object for a long time. The focal point formed by the line of sight on the display screen may be the intersection between the extension line of the line of sight in the direction of the line of sight and the surface of the display screen. Therefore, when the photographer's sight line is in the target object area for a long time corresponding to the focus on the display screen, the target object can be determined as the focused gazing object. Of course, other methods may also be used to determine the gaze object, which is not specifically limited in this embodiment of the present application.
例如，参照图3，其示出了本申请实施例提供的一种拍摄图像，在后置图像拍摄的如图3所示的图像中，假设拍摄者当前看向拍摄图像中的被拍摄者31，则拍摄者的视线在拍摄图像中对应的注视焦点22处于被拍摄者22的区域中。For example, referring to FIG. 3 , which shows a captured image provided by an embodiment of the present application, in the image shown in FIG. 3 captured by the rear image, it is assumed that the photographer is currently looking at the subject 31 in the captured image. , then the
步骤103、将所述注视对象作为防抖对象，对所述摄像头采集的目标图像进行目标防抖处理。Step 103: Use the gaze object as an anti-shake object, and perform target anti-shake processing on the target image collected by the camera.
在本申请实施例中，确定了用户所关注的注视对象后，基于拍摄者对注视对象在图像中具有更高成像效果的需求，可以设置前置摄像头或后置摄像头在拍摄注视对象时采用针对性的目标防抖处理，目标防抖处理具有对应的防抖强度值。以供电子设备的前置摄像头或后置摄像头在采集目标图像时，根据目标防抖处理对应的防抖强度值，确定对原始图像中像素点位置的补偿值，从而对原始图像进行像素点位置补偿，实现画面的防抖处理。In the embodiment of the present application, after determining the gaze object that the user pays attention to, based on the photographer's requirement for the gaze object to have a higher imaging effect in the image, the front camera or the rear camera can be set to use the target camera when photographing the gaze object. The target anti-shake processing has a corresponding anti-shake intensity value. When the front camera or rear camera of the electronic device collects the target image, according to the anti-shake intensity value corresponding to the target anti-shake processing, the compensation value for the pixel position in the original image is determined, so as to determine the pixel position of the original image. Compensation to achieve image stabilization.
进一步的，在利用电子设备的前置摄像头或后置摄像头进行录像时，也可以利用上述步骤确定注视对象的防抖强度，从而得到包含注视对象的视频，且该视频中的注视对象成像清晰、稳定，并尽可能的保留了拍摄画面中的其他信息。Further, when the front camera or the rear camera of the electronic device is used for video recording, the above steps can also be used to determine the anti-shake intensity of the staring object, so as to obtain a video including the staring object, and the staring object in the video has a clear and clear image. Stabilized and preserved as much as possible other information in the shot.
需要说明的是，当拍摄者的注视对象变更之后，可以将原有注视对象的防抖强度值恢复为初始值，并针对新的注视对象增加其对应的防抖强度值。It should be noted that, after the photographer's gaze object is changed, the anti-shake intensity value of the original gaze object can be restored to the initial value, and the corresponding anti-shake intensity value of the new gaze object can be increased.
综上所述，本申请实施例提供一种拍摄方法，通过显示由摄像头采集的预览图像；确定用户在预览图像中的注视对象；将注视对象作为防抖对象，对摄像头采集的目标图像进行目标防抖处理，本申请可以基于对拍摄者的视线追踪，确定拍摄者当前所关注的注视对象，并基于拍摄者对注视对象在图像中具有更高成像效果的需求，设置摄像头拍摄注视对象时具有针对性的目标防抖处理，为注视对象提供更好的防抖处理效果，使得防抖处理不再局限于单一景深范围内的物体，而是可以随着拍摄者的视线注视的对象的改变而改变其处理对象，提高了摄像头的防抖效果。To sum up, the embodiments of the present application provide a shooting method, by displaying a preview image collected by a camera; determining a user's gaze object in the preview image; Anti-shake processing, the present application can determine the gaze object that the photographer is currently paying attention to based on the gaze tracking of the photographer, and based on the photographer's requirement for the gaze object to have a higher imaging effect in the image, set the camera to shoot the gaze object with Targeted target anti-shake processing provides better anti-shake processing effect for the gazing object, so that the anti-shake processing is no longer limited to objects within a single depth of field range, but can be adjusted according to the change of the object the photographer is looking at. Changed its processing object to improve the camera's anti-shake effect.
参照图4，其示出了本申请实施例提供的一种拍摄方法的具体步骤示意图，包括：Referring to FIG. 4, it shows a schematic diagram of specific steps of a shooting method provided by an embodiment of the present application, including:
步骤201、显示由摄像头采集的预览图像。Step 201: Display the preview image collected by the camera.
该步骤具体可以参照上述步骤101，此处不再赘述。For details of this step, reference may be made to the foregoing
步骤202、确定用户在所述预览图像中的注视对象。Step 202 : Determine the gaze object of the user in the preview image.
该步骤具体可以参照上述步骤102，此处不再赘述。For details of this step, reference may be made to the foregoing
可选的，步骤202具体可以包括：Optionally,
子步骤2021、确定所述用户在所述预览图像中的注视焦点。Sub-step 2021: Determine the gaze focus of the user in the preview image.
在本申请实施例中，参照图3，前置摄像头可以采集拍摄者的瞳孔特征，从而确定拍摄者的视线的起始位置和视线方向，并根据视线的起始位置和视线方向，确定视线在显示屏中的注视焦点22。In the embodiment of the present application, referring to FIG. 3 , the front camera can collect the pupil characteristics of the photographer, so as to determine the starting position and direction of the photographer’s sight line, and determine whether the sight line is in the
子步骤2022、在所述注视焦点在目标对象中的目标区域中的停留时长，大于或等于预设时长的情况下，将所述目标对象确定为所述注视对象，所述目标区域的尺寸小于或等于预设尺寸范围。Sub-step 2022: In the case where the duration of stay of the gaze focus in the target area of the target object is greater than or equal to a preset duration, determine the target object as the gaze object, and the size of the target area is less than or equal to or equal to the preset size range.
具体的，判断哪个对象为拍摄者当前关注的对象，可以为判断在拍摄者的视线对应在显示屏上的注视焦点处于目标对象区域中的停留时长大于或等于预设时长时，将目标对象确定为关注对象。需要说明的是，预设时长可以根据实际需求进行设定，如两秒。Specifically, judging which object is the object that the photographer is currently paying attention to can be determined by judging that the target object is determined when the duration of the photographer's line of sight corresponding to the focus on the display screen is in the target object area is greater than or equal to the preset duration object of interest. It should be noted that the preset duration can be set according to actual needs, such as two seconds.
另外，在目标对象整体面积较大的情况下，判断拍摄者是否在关注该目标对象，可以通过判断注视焦点在目标对象中的目标区域中的停留时长，是否大于或等于预设时长来确定，该目标区域可以为目标对象的中心区域，也可以为其他重点区域，该目标区域可以具有较小尺寸，当拍摄者注视该目标区域较长时间时，可以认为包括该目标区域的目标对象为关注对象。In addition, when the overall area of the target object is large, to determine whether the photographer is paying attention to the target object, it can be determined by judging whether the staying time of the focus in the target area of the target object is greater than or equal to the preset time length, The target area can be the central area of the target object or other key areas. The target area can have a smaller size. When the photographer stares at the target area for a long time, it can be considered that the target object including the target area is the focus area. object.
如，在目标对象为人物时，目标区域可以为人物的脸部区域，在目标对象为汽车时，目标区域则可以为汽车中心位置的区域。For example, when the target object is a person, the target area may be the face area of the person, and when the target object is a car, the target area may be the area at the center of the car.
步骤203、对所述目标图像中的防抖对象，采用第一防抖强度值进行处理。Step 203: Use the first anti-shake intensity value to process the anti-shake object in the target image.
步骤204、对所述目标图像中的其他对象，采用第二防抖强度值进行处理。Step 204: Process other objects in the target image using the second anti-shake intensity value.
其中，所述第一防抖强度值大于所述第二防抖强度值。Wherein, the first anti-shake intensity value is greater than the second anti-shake intensity value.
在本申请实施例中，在确定了注视对象并将注视对象作为防抖对象之后，对防抖对象进行拍摄的摄像头可以以较高的第一防抖强度值对目标图像中的防抖对象进行处理，从而达到对画面中防抖对象的防抖效果，提升防抖对象的成像效果，另外，摄像头还可以以较低的第二防抖强度值对目标图像中除防抖对象之外的其他对象进行处理，这样可以使得最终成像中更加的突出防抖对象的成像效果。In the embodiment of the present application, after the gaze object is determined and the gaze object is used as the anti-shake object, the camera that shoots the anti-shake object can perform the anti-shake object in the target image with a higher first anti-shake intensity value. processing, so as to achieve the anti-shake effect on the anti-shake object in the picture, and improve the imaging effect of the anti-shake object. In addition, the camera can also use a lower second anti-shake intensity value. The object is processed, which can make the imaging effect of the anti-shake object more prominent in the final image.
例如，在拍摄人像时，拍摄者注视被拍摄的人像，则最终的成像中，人像区域清晰、稳定，而人像之外的背景则可以相对模糊，从而达到突出画面中以人像为重点表达的目的。For example, when shooting a portrait, the photographer looks at the portrait, and in the final image, the portrait area is clear and stable, while the background outside the portrait can be relatively blurred, so as to achieve the purpose of highlighting the portrait in the picture. .
可选的，对防抖对象采用第一防抖强度值进行处理具体可以包括：Optionally, using the first anti-shake intensity value to process the anti-shake object may specifically include:
步骤A1、通过陀螺仪获取所述电子设备的实际位移量。Step A1: Obtain the actual displacement of the electronic device through a gyroscope.
在本申请实施例中，抖动处理方法的目的是补偿因电子设备受到的实际物理偏移，而造成画面中对象的像素点偏移，因此，首先可以通过电子设备的陀螺仪获取电子设备的实际位移量。In the embodiment of the present application, the purpose of the jitter processing method is to compensate the pixel point of the object in the picture due to the actual physical offset of the electronic device. displacement.
步骤A2、根据所述实际位移量和所述第一防抖强度值，确定所述防抖对象在画面中的相对位移量。Step A2: Determine the relative displacement of the anti-shake object in the picture according to the actual displacement and the first anti-shake intensity value.
在本申请实施例中，在确定了拍摄者关注的防抖对象之后，可以基于提高后的第一防抖强度值和实际位移量，确定防抖对象在画面中的相对位移量。具体的，第一防抖强度值可以为一个权重系数，用于将电子设备的物理偏移转换为画面中对象的相对偏移，防抖对象的第一防抖强度值大于其他对象的第二防抖强度值。In this embodiment of the present application, after determining the anti-shake object that the photographer pays attention to, the relative displacement of the anti-shake object in the picture may be determined based on the improved first anti-shake intensity value and the actual displacement. Specifically, the first anti-shake strength value may be a weight coefficient, which is used to convert the physical offset of the electronic device into the relative offset of the object in the picture, and the first anti-shake strength value of the anti-shake object is greater than the second anti-shake strength value of other objects. Stabilization intensity value.
步骤A3、建立基于所述防抖对象的坐标系。Step A3, establishing a coordinate system based on the anti-shake object.
为了实现对二维画面中防抖对象的像素点的偏移补偿，可以建立基于注视对象的坐标系，以便于电子设备进行后续处理。In order to realize the offset compensation for the pixel points of the anti-shake object in the two-dimensional picture, a coordinate system based on the gaze object can be established, so as to facilitate subsequent processing by the electronic device.
步骤A4、根据所述相对位移量，对所述坐标系中防抖对象的像素点位置进行补偿，实现对所述防抖对象的防抖拍摄。Step A4: Compensate the pixel position of the anti-shake object in the coordinate system according to the relative displacement amount, so as to realize anti-shake shooting of the anti-shake object.
在本申请实施例中，根据相对位移量，对坐标系中防抖对象的像素点位置进行补偿，可以相对抵消因电子设备的物理偏移而带来的防抖对象的像素点的相对偏移，达到防抖对象成像清晰、稳定的效果，从而实现对防抖对象的防抖拍摄。In the embodiment of the present application, the pixel position of the anti-shake object in the coordinate system is compensated according to the relative displacement, which can relatively offset the relative offset of the pixel point of the anti-shake object caused by the physical offset of the electronic device. , to achieve a clear and stable image of the anti-shake object, so as to realize the anti-shake shooting of the anti-shake object.
可选的，在步骤202之后，还可以包括：Optionally, after
步骤205、确定所述用户在所述预览图像中的注视焦点。Step 205: Determine the gaze focus of the user in the preview image.
步骤206、确定所述注视焦点在所述预览图像中位移的次数和每次位移的位移量。Step 206: Determine the number of times the gaze focus is displaced in the preview image and the displacement amount of each displacement.
在本申请实施例中，拍摄者的视线可能因一些原因处于游移不定的状态，此时可以认为拍摄者并未进行对注视对象的关注，可能只是在随意观看，为了识别出拍摄者的这种状态，电子设备可以通过前置摄像头的监控，确定拍摄者的视线对应的注视焦点在预览图像中位移的次数和每次位移的位移量。In the embodiment of the present application, the photographer's line of sight may be in a state of wandering due to some reasons. At this time, it can be considered that the photographer did not pay attention to the object he was looking at. The electronic device can determine the number of times the focus of gaze corresponding to the photographer's sight line is displaced in the preview image and the displacement amount of each displacement through the monitoring of the front camera.
步骤207、在所述位移量大于或等于预设位移量的位移的数量大于预设数量，且相邻位移之间的时间间隔小于或等于预设时间间隔的情况下，对所述摄像头采集的目标图像进行预设防抖处理，所述预设防抖处理与所述目标防抖处理不同。Step 207: Under the condition that the number of displacements with the displacement amount greater than or equal to the preset displacement amount is greater than the preset number, and the time interval between adjacent displacements is less than or equal to the preset time interval, collect the data collected by the camera. The target image is subjected to preset anti-shake processing, and the preset anti-shake processing is different from the target anti-shake processing.
在本申请实施例中，当拍摄者的注视点的位移量大于或等于预设位移量的位移的数量大于预设数量时，可以认为拍摄者的注视点一直频繁的大范围变动，从而判断拍摄者并未重点关注屏幕中的信息，此时可以进行预设防抖处理，预设防抖处理可以为设备默认的防抖处理，即不专门针对某一目标对象实现防抖，避免造成画面频繁移动。In the embodiment of the present application, when the displacement of the photographer's gaze point is greater than or equal to the preset displacement amount and the number of displacements is greater than the preset number, it can be considered that the photographer's gaze point has been changing frequently and in a large range, so as to judge the shooting If the user does not focus on the information on the screen, the preset anti-shake processing can be performed at this time. The preset anti-shake processing can be the default anti-shake processing of the device, that is, it does not specifically implement anti-shake for a certain target object, so as to avoid frequent images. move.
具体的，默认防抖处理可以为按照预设的防抖强度值，对后置摄像头采集的画面中的背景区域进行防抖处理。另外，当拍摄场景中出现较多景深距离远近不同的对象时，还可以将景深距离较远的所有对象同一划分为背景区域，使得这些景深距离较远的对象统一作为一个整体，避免因对象过多而导致注视对象确定困难的问题发生。Specifically, the default anti-shake processing may be to perform anti-shake processing on the background area in the picture captured by the rear camera according to a preset anti-shake intensity value. In addition, when there are many objects with different depth-of-field distances in the shooting scene, all objects with far-field depth-of-field distances can also be divided into the background area, so that these objects with far-field depth-of-field distances can be unified as a whole, so as to avoid the objects too far away. There are many problems that make it difficult to determine the gaze object.
