The scene reminding method provided by the embodiment of the disclosure can be used for shooting devices such as cameras, video cameras and the like. The imaging device may be independent or may be installed in a terminal, for example, a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like.
As shown in fig. 1, fig. 1 is a view processing method according to an exemplary embodiment, including the steps of:
in step 101, when a subject is photographed, determining a target scene corresponding to the subject currently;
in step 102, determining at least one candidate scene according to the target scene; the alternative scene is a scene different from the target scene, and the corresponding range of the shot subject in the current frame is smaller than the corresponding range of the shot subject in the current frame when the alternative scene is the target scene;
in step 103, first candidate capturing contents for capturing the subject in different candidate scenes are generated.
In the above embodiment, when the shooting device shoots a subject, the target scene corresponding to the subject currently can be determined, and further, at least one alternative scene is determined according to the target scene. And automatically generating first alternative shooting contents for shooting the shot subject under different alternative scenes respectively. Through the process, the scene difference is introduced into the shooting device, and when a user shoots the target scene through the shooting device, the shooting device can automatically and respectively shoot the shot main body under different alternative scenes, so that different first alternative shooting contents are obtained, the intelligent degree of the shooting device is improved, and the user experience is improved.
With regard to the above step 101, it may be determined that the subject needs to be photographed after it is detected that the user opens the viewfinder of the photographing apparatus. In the embodiment of the present disclosure, the subject to be photographed may be a person, an animal, a moving or immovable object, a landscape, or the like, optionally.
As shown in fig. 2, fig. 2 is another scene processing method based on the foregoing embodiment shown in fig. 1, and step 101 may include the following steps:
in step 101-1, determining current range information corresponding to the subject to be photographed; the current range information is used for representing the range information of the shot subject appearing in the current frame;
in this step, the current frame in the viewfinder may be automatically analyzed by the camera to determine the current range information. For example, the subject to be photographed is a person, and the corresponding current range information is a 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 animal.
The current frame is shot by a certain camera of the shooting device, such as a camera a.
In step 101-2, a scene corresponding to the current range information is set as the target scene based on a predetermined correspondence between range information and scenes of the subject to be photographed.
In the embodiment of the present disclosure, the correspondence relationship may be as shown in fig. 3A. If the shot subject appearing in the current frame is a human body, the range above the shoulders of the human body corresponds to the close-up view, the range above the chest of the human body corresponds to the close-up view, the range above the knees of the human body corresponds to the middle view, all the corresponding views of the human body are panoramic views, and the corresponding views of the environment where the shot subject and the shot subject are located are long-range views.
In this step, the scene corresponding to the current range information may be determined as the target scene according to the correspondence. For example, as shown in fig. 3B, if the current range information is all of the human body, the target scene is a panorama.
After the camera determines the target scene, at least one alternative scene may also be determined, as described above with respect to step 102. The alternative scene is a scene different from the target scene, and the corresponding range of the shot subject in the current frame is smaller than the corresponding range of the shot subject in the current frame when the alternative scene is the target scene.
For example, if the target scene is a panorama, the alternative scene may be a medium scene, a close-up scene, or a close-up scene.
In step 103, the user may capture the subject in the target scene through another camera, for example, the camera B, on the capturing device, different from the camera that captures the current frame, and at the same time, the capturing device may generate the first candidate capturing content for capturing the subject in the different candidate scenes in the background.
As shown in fig. 4, fig. 4 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and step 103 may include the following steps:
in step 103-1, determining alternative range information corresponding to different alternative scenes according to a predetermined correspondence between range information of a subject to be photographed and scenes;
in this step, once the candidate scene is determined, the candidate range information may be determined according to the correspondence. For example, if the candidate scene is a medium scene, the corresponding candidate range information is a range above the knee of the human body.
In step 103-2, respectively determining corresponding alternative focal length values according to the alternative range information, where the alternative focal length values are focal length values that make the corresponding range information of the subject in the current frame be the alternative range information;
in this step, the shooting device may automatically adjust the focal length value, so that the range information corresponding to the shot subject in the current frame is the alternative range information, and the corresponding focal length value is the alternative focal length value at this time. In the embodiment of the present disclosure, each alternative scene may correspond to one alternative focal length value.
In step 103-3, the subject to be photographed is photographed by using the different candidate focal length values, respectively, to obtain the first candidate photographing content.
In this step, the shooting device may shoot the subject at the background by using the different alternative focal length values determined in the above steps, so as to obtain the first alternative shooting content.
In the embodiment of the present disclosure, assuming that the target view is a panorama, and the alternative views are a medium view, a close view, and a close-up, the shooting device may respectively adopt different alternative focal length values at the background to obtain first alternative shooting contents corresponding to the medium view, the close-up, and the close-up.
In an embodiment, as shown in fig. 5, fig. 5 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and the method may further include the following steps:
in step 104, outputting a preset virtual key for playing different first alternative shooting contents;
in this step, the shooting device may output a preset virtual key for playing different first candidate shooting contents on the current frame, for example, the preset virtual key for close-up and close-up shown in fig. 6.
In step 105, if it is detected that the preset virtual key is triggered, playing the first candidate shooting content corresponding to the preset virtual key.
In this step, if the user triggers a preset virtual key, the shooting device may play the first candidate shooting content corresponding to the preset virtual key.
For example, in fig. 6, if the user triggers a preset virtual key corresponding to the close range, the shooting device may automatically play the first alternative shooting content shot in the close range.
In the above embodiment, after the user triggers the preset virtual key, the first alternative shooting content corresponding to the preset virtual key is automatically played, so that the user can quickly adjust to a favorite frame, the switching process is more flexible, and the intelligent degree and the user experience of the shooting device are improved.
In an embodiment, if the number of the subjects to be photographed is multiple, for example, multiple persons, animals, etc., the step 103 may specifically be:
and generating the first candidate shooting contents for shooting each subject under different candidate scenes respectively.
That is, the imaging device can generate candidate imaging contents for imaging each subject in different candidate scenes in the background.
For example, as shown in fig. 7, the target view is a panorama, and the subject to be photographed includes two characters, namely a girl and a mom, the photographing device may respectively photograph the two characters in the medium view to obtain the first candidate photographing contents corresponding to the two characters. If the user triggers the preset virtual key of the middle scenery 1 corresponding to the girl, the first alternative shooting content under the middle scenery corresponding to the girl can be played, and if the user triggers the preset virtual key of the middle scenery 2 corresponding to the mom, the first alternative shooting content under the middle scenery corresponding to the mom can be played.
In the above embodiment, when the number of subjects is plural, the first candidate capturing contents for capturing each subject in the different candidate scenes may be automatically generated by the capturing device. The intelligent degree of the shooting device is further improved, and the user experience is improved.
In an embodiment, as shown in fig. 8, fig. 8 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and the method may further include the following steps:
in step 106, outputting a label corresponding to each subject;
in this step, the shooting device can perform face recognition on the current frame, and automatically recognize a plurality of shot subjects. Further, a label corresponding to each subject may be output at a position corresponding to each subject, for example, obliquely above or the like.
Alternatively, the label may be in text form, such as shown in FIG. 9A; or may be a face box, such as shown in fig. 9B. The present disclosure is not limited thereto.
In step 107, if it is detected that any of the tags is selected, the subject corresponding to the selected tag is photographed in the target scene.
In this step, if the user selects one of the tags, the subject to be photographed corresponding to the selected tag may be photographed in the current target scene. Namely, only the subject to be shot under the target scene is shot.
In the above embodiment, the shooting device can shoot the target corresponding to the tag by the shooting subject under the target scene after determining that any tag is selected, so that the user can quickly select the object to be shot, the intelligent degree of the shooting device is improved, and the user experience is improved.
In an embodiment, as shown in fig. 10, fig. 10 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 8, and the method may further include the following steps:
in step 108, second candidate capturing contents for capturing the target subject in different candidate scenes are generated.
In this step, the shooting device may shoot the subject to be shot at the background under different alternative scenes, thereby obtaining the second alternative shooting content.
For example, as shown in fig. 11, when the camera detects that the user selects the tab corresponding to the girl, the camera may provide only the second alternative photographic content in the different alternative view corresponding to the girl.
In the above embodiment, only the second alternative shooting contents of the target shot subject in different scenes can be provided in the plurality of shot subjects according to the selection of the user, so that the intelligent degree of the shooting device is further improved, and the user experience is improved.
Of course, in the embodiment of the present disclosure, when the distance value between the subject and the shooting device is sufficient, the shooting device may also provide a preview of the panorama and/or the long-range view corresponding to the entire scene, where the lens of the shooting device is not focused on a certain subject, but includes the entire scene. If the user selects a panoramic or tele-view, the selected tab may not be displayed in the preview.
In an embodiment, as shown in fig. 12, fig. 12 is another scene prompting method shown on the basis of the embodiment shown in fig. 8, and the scene prompting method may further include the following steps:
in step 109, after detecting that the target scene is locked, if the shooting distance value between the shooting device and the target subject is changed, determining target range information corresponding to the target scene according to the predetermined correspondence between the range information of the subject and the scene;
in this step, the shooting device may detect whether a preset virtual key for locking the target scene is triggered, and if the preset virtual key is triggered by the user, the shooting device may determine that the target scene needs to be locked currently.
The photographing apparatus may periodically detect whether range information of the subject to be photographed in the current frame is changed, and if so, may determine that the photographing distance value is changed. Further, the photographing device may determine target range information corresponding to the target scene according to the correspondence. For example, if the target scene is a close scene, the target range information is a range above the chest of the human body.
In step 110, a target focal length value is determined according to the target range information, where the target focal length value is a focal length value that allows the range information corresponding to the target subject in the current frame to be the target range information.
In this step, the shooting device can adjust the current focal length to the target focal length value, and keep the range information of the target shot subject in the frame as the target range information all the time, so that the target shot subject is always in the target scene.
In step 111, the target subject is photographed using the target focal length value.
In this step, after the photographing device is adjusted to the target focal length value, the subject to be photographed of the target may be photographed by using the target focal length value. For example, the subject of the target object is a person, and the shooting device can automatically focus on the face of the person, so that the person is always under the target scene, and the face of the person always exists in the target scene.
In the embodiment, after the target scene is locked, the shooting device can automatically focus, so that the face can not appear on the picture. The intelligent degree of the shooting device is improved, and the user experience is improved.
In an embodiment, as shown in fig. 13, fig. 13 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 8, and the scene prompting method may further include the following steps:
in step 112, when it is required to switch from the target scene to any one of the candidate scenes, the volume value corresponding to the target subject is increased, and the volume values corresponding to other subjects and noise are decreased.
If the user selects to process the target subject's view from the target view to an alternative view, for example, when the distant view is switched to the near view, the shooting device may automatically call a sound collection device, such as a microphone, to increase the volume value corresponding to the target subject, and at the same time, to decrease the volume values corresponding to other subjects and the noise.
In the above embodiment, when the scene is switched, the volume value corresponding to the target subject to be photographed may be adjusted to highlight the sound of the target subject to be photographed, so that the scene processing is more stereoscopic. The intelligent degree of the shooting device is improved, and the user experience is improved.
In one embodiment, as shown in FIG. 14, FIG. 14 is another scene processing method according to an exemplary embodiment, the method comprising the steps of:
