背景技术Background technique
当前是一个全民摄影的时代，人们对拍摄图像中画面元素的成像质量具有较高要求。At present, it is an era of national photography, and people have high requirements for the imaging quality of the picture elements in the captured images.

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的图像处理方法、装置和电子设备进行详细地说明。The image processing method, apparatus, and electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
参照图1，其示出了本申请实施例提供的一种图像处理方法的步骤示意图，包括：Referring to FIG. 1, it shows a schematic diagram of steps of an image processing method provided by an embodiment of the present application, including:
步骤101、在多个景深范围中选取至少一个目标景深范围。Step 101: Select at least one target depth of field range from multiple depth of field ranges.
景深(DOF，Depth of Field)，是指为了摄影机镜头或其他成像器前沿能够取得清晰图像的成像，所测定的被摄物体前后距离范围，即在摄像机聚焦完成后，焦点前后的范围内所呈现的清晰图像的距离为景深，摄像机的光圈、镜头、及焦平面到拍摄物的距离是影响景深的重要因素。Depth of Field (DOF, Depth of Field) refers to the range of distance before and after the subject that is measured in order to obtain a clear image at the front of the camera lens or other imagers, that is, after the camera is focused, the range before and after the focus is presented. The distance of the clear image is the depth of field. The distance from the aperture, lens, and focal plane of the camera to the subject is an important factor affecting the depth of field.
目前电子设备的摄像机受到光圈、镜头等硬件的限制，并不能够满足一次拍摄得到的一张图像中，同时对所有景深范围对应的元素都成像清晰的需求，如，拍摄清晰的近景人物时，会导致背景模糊。At present, the camera of electronic equipment is limited by hardware such as aperture and lens, and cannot meet the requirement of clear imaging of all elements corresponding to the depth of field in one image obtained at a time. For example, when shooting clear close-up people, will cause the background to be blurred.
本申请实施例中，不同的景深范围可以对应拍摄场景中不同远近的物体，如，参照图2，其示出了本申请实施例提供的一种拍摄图像示意图，在一张拍摄图像中，可以将景深范围划分为远景范围、中景范围、近景范围，远景范围对应较远距离的物体，中景范围对应适中距离的物体，近景范围对应较近距离的物体，用户在进行拍摄时，为了实现丰富的画面效果，通常具有不同的景深需求，如，参照图2，假设近景范围对应的物体为人物，用户想拍摄一张突出近景人物12的人物图像，则用户可以在近景范围下进行对焦及拍摄，得到一张近景人物12清晰，其他作为背景的远景物体10和适中物体11模糊的人物图像，使得画面中的人物得到突出。另外，用户也可以基于较高的成像需求，要求最终拍摄图像中，远景范围、中景范围、近景范围中多个范围对应的物体成像清晰。In the embodiment of the present application, different depth-of-field ranges may correspond to objects of different distances in the shooting scene. For example, referring to FIG. 2 , which shows a schematic diagram of a captured image provided by the embodiment of the present application, in a captured image, you can The depth-of-field range is divided into long-range, medium-range, and close-range. The far-range corresponds to distant objects, the medium-range corresponds to moderate-distance objects, and the close-range corresponds to closer objects. When the user is shooting, in order to achieve Rich picture effects usually have different depth-of-field requirements. For example, referring to Figure 2, assuming that the object corresponding to the close-range range is a person, and the user wants to shoot a person image that highlights the close-
因此，电子设备的摄像机可以基于自身能力能够提供的多个景深范围，由用户根据成像需求，选取其中的至少一个目标景深范围，以供目标景深范围对应的物体在最终成像中成像清晰。电子设备可以包括手机、相机、手表、航拍器等设备。Therefore, the camera of the electronic device can select at least one target depth of field range based on the multiple depth-of-field ranges that its own capabilities can provide, so that the object corresponding to the target depth-of-field range can be clearly imaged in the final imaging by the user. Electronic devices may include mobile phones, cameras, watches, aerial cameras and other devices.
步骤102、按照相同的曝光参数和相机姿态，分别对每个目标景深范围对应的物体进行对焦及拍摄，得到每个所述目标景深范围对应的初始图像。
在本申请实施例中，为了满足用户对目标景深范围对应的物体在最终成像中成像清晰的需求，首先需要获取各个目标景深范围下摄像机拍摄的初始图像，每个目标景深范围对应的初始图像中，该目标景深范围对应的物体成像清晰。In the embodiment of the present application, in order to meet the user's requirement for the object corresponding to the target depth of field to be clearly imaged in the final imaging, it is first necessary to obtain the initial image captured by the camera under each target depth of field. , the image of the object corresponding to the target depth of field range is clear.
例如，用户要求对近景和远景对应物体成像清晰，则在用户选取了远景范围和近景范围作为目标景深范围后，摄像机基于相同的曝光参数和相机姿态，针对远景范围进行对焦及拍摄，得到一张初始图像，并针对近景范围进行对焦及拍摄，得到另一张初始图像。For example, if the user requires a clear image of the objects corresponding to the near-field and far-field, after the user selects the far-field range and the near-field range as the target depth-of-field range, the camera will focus and shoot for the far-field range based on the same exposure parameters and camera posture, and get a picture The initial image, and focus and shoot for the close-range range to obtain another initial image.
具体的，摄像机在拍摄初始图像时，需要按照相同的曝光参数和相机姿态，分别对每个目标景深范围对应的物体进行对焦及拍摄，相同的曝光参数和相机姿态可以保证拍摄的初始图像中边缘特征一致，避免后续合成时出现缝隙等缺陷。Specifically, when the camera shoots the initial image, it needs to focus and shoot the objects corresponding to each target depth of field according to the same exposure parameters and camera posture. The same exposure parameters and camera posture can ensure that the initial image is captured. The features are consistent to avoid defects such as gaps in subsequent synthesis.
在本申请实施例中，相同的相机姿态可以指：通过相机对每个目标景深范围对应的物体进行对焦及拍摄时，该相机相对于物体的三维姿态欧式角(俯仰角，偏航角，滚轮角)相同。In the embodiment of the present application, the same camera posture may refer to: when focusing and photographing an object corresponding to each target depth of field by the camera, the Euclidean angle (pitch angle, yaw angle, scroll wheel, etc.) of the camera relative to the three-dimensional posture of the object angle) are the same.
因此，摄像机需要具有较高的响应速度，并且在拍摄不同初始图像时，间隔时间较短，以降低相机姿态变化带来的影响。Therefore, the camera needs to have a high response speed, and when shooting different initial images, the interval time is short, so as to reduce the influence of the camera attitude change.
步骤103、在选取了一个所述目标景深范围的情况下，将所述目标景深范围对应的初始图像作为目标图像。Step 103: In the case that one of the target depth of field ranges is selected, the initial image corresponding to the target depth of field range is used as the target image.
在本申请实施例中，若用户仅选取了一个景深范围作为目标景深范围，则可以将该目标景深范围对应的初始图像直接作为目标图像进行输出，例如，用户想拍摄一张突出近景人物的人物图像，则用户可以将近景范围作为目标景深范围，并在近景范围下进行对焦及拍摄，得到一张人物清晰，其他作为背景的物体模糊的人物图像，使得画面中的人物得到突出。In the embodiment of the present application, if the user selects only one depth of field range as the target depth of field range, the initial image corresponding to the target depth of field range may be directly output as the target image. image, the user can use the near-field range as the target depth of field range, and focus and shoot in the near-field range to obtain a person image with a clear person and blurred other objects as the background, making the person in the picture stand out.
步骤104、在选取了多个所述目标景深范围的情况下，对所有所述目标景深范围对应的初始图像进行图像融合，得到目标图像。Step 104: In the case of selecting a plurality of the target depth of field ranges, perform image fusion on the initial images corresponding to all the target depth of field ranges to obtain a target image.
在本申请实施例中，在选取了多个目标景深范围的情况下，摄像机会针对每个目标景深范围拍摄对应的初始图像，且初始图像中对应目标景深范围的画面元素清晰度最高，因此，可以为每个初始图像中清晰度最高的画面元素分配较高的融合权重，使得在进行所有目标景深范围对应的初始图像的融合之后，可以在最终的目标图像中保留各个初始图像中清晰度最高的画面元素，达到最终的目标图像中对应目标景深范围的画面元素全部清晰显示的目的。In the embodiment of the present application, when multiple target depth-of-field ranges are selected, the camera will shoot a corresponding initial image for each target depth-of-field range, and the picture elements corresponding to the target depth-of-field range in the initial image have the highest definition. Therefore, A higher fusion weight can be assigned to the picture element with the highest definition in each initial image, so that after all initial images corresponding to the target depth of field are fused, the highest definition in each initial image can be retained in the final target image. To achieve the purpose of clearly displaying all the picture elements corresponding to the target depth of field in the final target image.
例如，参照图2，景深范围划分为远景范围、中景范围、近景范围，假设用户选取了近景范围、中景范围、远景范围作为目标景深范围，则摄像机可以按照相同的曝光参数和相机姿态，分别针对近景范围、中景范围、远景范围进行拍摄，得到如图3、图4、图5所示的三张初始图像，图3所示的初始图像中对应近景范围的物体12显示清晰，图4所示的初始图像中对应中景范围的物体11显示清晰，图5所示的初始图像中对应远景范围的物体10显示清晰，将这三张初始图像中显示清晰的物体的区域提取并融合为一张目标图像，可以使得目标图像中远中近物体都显示清晰。需要说明的是，也可以在对初始图像中显示清晰的物体的区域添加较高融合权重后，对三个初始图像进行基于融合权重的融合操作，以得到最终的目标图像。For example, referring to FIG. 2 , the depth of field range is divided into long-range, medium-range, and close-range. Assuming that the user selects the near-range, medium-range, and long-range as the target depth-of-field range, the camera can follow the same exposure parameters and camera posture, Shooting for the close-range, medium-range, and distant-range, respectively, to obtain three initial images as shown in Fig. 3, Fig. 4, and Fig. 5. In the initial image shown in Fig. 3, the
在实际应用中，用户可以通过选取操作选取至少一个目标景深范围，选取之后，摄像机可以自动根据目标景深范围拍摄对应的初始图像，并自动将所有初始图像进行融合得到目标图像，并将目标图像提供给用户，整个过程中，用户不需要进行过多繁琐的操作。In practical applications, the user can select at least one target depth of field range through the selection operation. After selection, the camera can automatically shoot the corresponding initial image according to the target depth of field range, and automatically fuse all the initial images to obtain the target image, and provide the target image with For the user, in the whole process, the user does not need to perform too many cumbersome operations.
综上所述，本申请实施例提供一种图像处理方法，在多个景深范围中选取至少一个目标景深范围；按照相同的曝光参数和相机姿态，分别对每个目标景深范围对应的物体进行对焦及拍摄，得到每个目标景深范围对应的初始图像；在选取了一个目标景深范围的情况下，将目标景深范围对应的初始图像作为目标图像；在选取了多个目标景深范围的情况下，对所有目标景深范围对应的初始图像进行图像融合，得到目标图像，本申请可以基于用户对景深的需求，使得将用户所选取的所有目标景深范围所对应的画面元素，在最终展示的图像中显示清晰，解决了现有技术中仅能对一种景深范围对应的画面元素实现清晰显示的问题，满足了用户对拍摄图像中更多数量的画面元素都具备较高成像质量的要求。To sum up, the embodiments of the present application provide an image processing method, wherein at least one target depth of field range is selected from a plurality of depth of field ranges; according to the same exposure parameters and camera posture, the objects corresponding to each target depth of field range are respectively focused and shooting to obtain the initial image corresponding to each target depth of field range; when one target depth of field range is selected, the initial image corresponding to the target depth of field range is used as the target image; when multiple target depth of field ranges are selected, the All the initial images corresponding to the target depth of field are image-fused to obtain the target image. Based on the user's demand for the depth of field, the present application can make the picture elements corresponding to all the target depth of field selected by the user to be displayed clearly in the final displayed image. , which solves the problem in the prior art that only a picture element corresponding to one depth of field range can be clearly displayed, and satisfies the user's requirement for higher imaging quality for a larger number of picture elements in the captured image.
参照图6，其示出了本申请实施例提供的一种图像处理方法的具体步骤示意图，包括：Referring to FIG. 6, it shows a schematic diagram of specific steps of an image processing method provided by an embodiment of the present application, including:
步骤201、按照相同的曝光参数和相机姿态，分别对每个景深范围对应的物体进行对焦及拍摄，，得到每个所述景深范围对应的景深图像。
用户在使用拍摄功能时，具有对当前拍摄场景的画面预览需求，即在用户点击拍摄按钮之前，电子设备会显示摄像机采集到的拍摄场景的预览画面，以供用户参考。在本申请实施例中，在用户开启摄像功能后，摄像机可以按照相同的曝光参数和相机姿态，分别对每个景深范围对应的物体进行对焦及拍摄，，得到每个景深范围对应的景深图像，每个景深图像中对应该景深范围的画面元素成像清晰，将所有景深图像进行融合之后，可以得到摄像机能提供的所有景深范围对应的画面元素都显示清晰的预览图像，以供用户参考。When using the shooting function, the user has a need for a preview of the current shooting scene, that is, before the user clicks the shooting button, the electronic device will display the preview screen of the shooting scene captured by the camera for the user's reference.

进一步的，参照图7，其示出了本申请实施例提供的一种预览图像的示意图，为了在预览画面中显著区分不同景深范围对应的画面元素的区域，可以在预览画面中将不同的景深范围对应的画面元素的区域显示不同的元素，如，将远景范围对应的物体10的区域显示红色色调，将中景范围对应的物体11的区域显示蓝色色调，将近景范围对应的物体12的区域显示绿色色调。Further, referring to FIG. 7 , which shows a schematic diagram of a preview image provided by an embodiment of the present application, in order to significantly distinguish the areas of picture elements corresponding to different depth-of-field ranges in the preview image, different depth-of-field ranges can be displayed in the preview image.
