针对上述步骤101，可以在检测到用户打开了拍摄装置的取景器之后，确定需要对被拍摄主体进行拍摄。在本公开实施例中，可选地，所述被拍摄主体可以是人物、动物、移动或者不能移动的物体、风景等等。For theabove step 101, it may be determined that the subject to be photographed needs to be photographed after it is detected that the user has opened the viewfinder of the photographing device. In the embodiment of the present disclosure, optionally, the photographed subject may be a person, an animal, a moving or immovable object, a landscape, and the like.

如图2所示，图2是在前述图1所示实施例的基础上示出的另一种景别提醒方法，步骤101可以包括以下步骤：As shown in FIG. 2, FIG. 2 is another scene reminder method shown on the basis of the aforementioned embodiment shown in FIG. 1. Step 101 may include the following steps:

在步骤101-1中，确定所述被拍摄主体所对应的当前范围信息；所述当前范围信息用于表征所述被拍摄主体出现在当前画幅中的范围信息；In step 101-1, the current range information corresponding to the photographed subject is determined; the current range information is used to represent the range information of the photographed subject appearing in the current frame;

本步骤中，可以由拍摄装置自动对取景器中的当前画幅进行分析，确定所述当前范围信息。例如，被拍摄主体是人物，对应的当前范围信息是人体肩部以上的范围；或者被拍摄主体是动物，对应的当前范围信息是动物的整体。In this step, the photographing device may automatically analyze the current frame in the viewfinder to determine the current range information. For example, if the subject to be photographed is a person, the corresponding current range information is the range above the shoulder of the human body; or the subject to be photographed is an animal, and the corresponding current range information is the whole of the animal.

在步骤101-2中，根据预先确定的被拍摄主体的范围信息和景别之间的第一对应关系，将与所述当前范围信息所对应的景别作为所述目标景别。In step 101-2, according to the predetermined first correspondence between the range information of the subject and the scene type, the scene type corresponding to the current range information is used as the target scene type.

在本公开实施例中，所述第一对应关系可以如图3A所示。如果在当前画幅中出现的被拍摄主体为人体，则人体肩部以上的范围对应景别为特写，人体胸部以上的范围对应景别为近景，人体膝部以上的范围对应景别为中景，人体的全部所对应的景别为全景，被摄体主体和被拍摄主体所处处环境对应的景别为远景。In this embodiment of the present disclosure, the first corresponding relationship may be as shown in FIG. 3A . If the subject appearing in the current frame is a human body, the range above the shoulders of the human body corresponds to a close-up, the range above the human chest corresponds to a close-up, and the range above the human knee corresponds to a medium shot. The scenes corresponding to all the human body are panorama, and the scenes corresponding to the subject and the environment in which the subject is located are distant.

本步骤中，可以根据上述第一对应关系，确定与当前范围信息对应的景别为目标景别。例如图3B所示，当前范围信息为人体的全部，则目标景别为全景。In this step, the scene category corresponding to the current range information may be determined as the target scene category according to the first corresponding relationship. For example, as shown in FIG. 3B , the current range information is the entire human body, and the target scene is a panoramic view.

针对上述步骤102，可选地，拍摄装置可以在当前画幅的左上角显示所述第一目标提示信息。或者拍摄装置也可以在其他位置显示所述第一目标提示信息，本公开对此不作限定。For theabove step 102, optionally, the photographing device may display the first target prompt information in the upper left corner of the current frame. Alternatively, the photographing device may also display the first target prompt information at other positions, which is not limited in the present disclosure.

本公开实施例中，所述目标标准景别是可以恰好达到所述目标景别所对应的景别标准的景别。其中，所述景别标准可以是每个景别所对应的准确的范围信息。例如，目标景别为中景，景别标准为人体膝部以上的范围，则被拍摄主体恰好在当前画幅中显示到膝部以上的范围时，即为中景标准景别。In the embodiment of the present disclosure, the target standard scene category is a scene category that can just reach the scene category standard corresponding to the target scene category. Wherein, the scene category standard may be accurate range information corresponding to each scene category. For example, if the target scene is a medium shot, and the standard of the scene is the range above the knee of the human body, when the subject is just displayed in the range above the knee in the current frame, it is the standard shot of the medium shot.

可选地，拍摄装置可以预先通过卷积神经网络对拍摄画幅进行训练，获得标准景别模型，所述标准景别模型中包括了不同景别各自对应的标准景别。Optionally, the photographing device may pre-train the photographed frame through a convolutional neural network to obtain a standard scene category model, where the standard scene category model includes respective standard scene categories corresponding to different scene categories.

本步骤中，可以通过第一目标提示信息提示用户手动移动拍摄装置第一目标距离值，从而达到所述目标标准景别。或者可以通过第一目标提示信息提示用户可以由拍摄装置自动切换到目标标准景别。In this step, the user may be prompted to manually move the first target distance value of the photographing device through the first target prompt information, so as to achieve the target standard scene. Alternatively, the user may be prompted through the first target prompt information that the photographing device can automatically switch to the target standard scene.

如果用户根据第一目标提示信息，选中用于切换到目标标准景别的虚拟按键，例如图3C所示，则由拍摄装置自动切换到所述目标标准景别下。If the user selects a virtual button for switching to the target standard scene according to the first target prompt information, such as shown in FIG. 3C , the camera will automatically switch to the target standard scene.

可选地，如果用户未选中用于切换到目标标准景别的虚拟按键，则用户在通过拍摄装置的第一摄像头在目标景别下对被拍摄主体进行拍摄，获得第一拍摄内容的过程中，由拍摄装置在后台自动基于目标标准景别，采用不同于第一摄像头的第二摄像头对被拍摄主体进行同步拍摄，获得第二拍摄内容。从而可以在用户完成拍摄之后，将第一拍摄内容和第二拍摄内容提供给用户，便于用户从中选择出更合适的拍摄内容。Optionally, if the user does not select the virtual button for switching to the target standard scene, then the user shoots the subject to be photographed under the target scene through the first camera of the shooting device, and obtains the first shooting content in the process. , the photographing device automatically uses a second camera different from the first camera to synchronously photograph the subject to be photographed in the background based on the target standard scene, and obtains the second photographing content. Therefore, after the user completes shooting, the first shooting content and the second shooting content can be provided to the user, so that the user can select a more suitable shooting content from them.

在一实施例中，如图4所示，图4是在前述图1所示实施例的基础上示出的另一种景别提醒方法，确定第一目标距离值的过程包括以下步骤：In one embodiment, as shown in FIG. 4 , which is another scene-specific reminder method shown on the basis of the embodiment shown in the foregoing FIG. 1 , the process of determining the first target distance value includes the following steps:

本步骤中，所述第一拍摄距离值与所述第二拍摄距离值之间的差值可以直接作为第一目标距离值。如果第一拍摄距离值和第二拍摄距离值均为范围值，则可以将两者差值的最小值和最大值之间的范围值作为所述第一目标距离值。In this step, the difference between the first shooting distance value and the second shooting distance value may be directly used as the first target distance value. If both the first shooting distance value and the second shooting distance value are range values, the range value between the minimum value and the maximum value of the difference between the two may be used as the first target distance value.

其中，如果第一拍摄距离值大于第二拍摄距离值，则所述目标提示信息可以提示用户向前移动，如果第一拍摄距离值小于第二拍摄距离值，则所述目标提示信息可以提示用户向后移动。Wherein, if the first shooting distance value is greater than the second shooting distance value, the target prompt information may prompt the user to move forward, and if the first shooting distance value is less than the second shooting distance value, the target prompt information may prompt the user Move backwards.

例如，第一拍摄距离值为1至1.2米，第二拍摄距离值为1.8至2.5米，则所述第一目标距离值可以为0.5至1.3米。For example, if the first shooting distance value is 1 to 1.2 meters, and the second shooting distance value is 1.8 to 2.5 meters, the first target distance value may be 0.5 to 1.3 meters.

本公开实施例中，可以在第一目标提示信息中提示用户移动拍摄装置达到第一目标距离值的最小值时，可以达到所述目标标准景别，例如图5所示，向后移动0.5可以达到中景标准景别。In the embodiment of the present disclosure, when the user is prompted in the first target prompt information to move the photographing device to reach the minimum value of the first target distance, the target standard scene can be reached. For example, as shown in FIG. 5 , moving backward by 0.5 can Achieving the mid-range standard.
