Object characteristics typically include the type of object, such as trees, cats, dogs, and people; parts of objects such as the face, torso, and legs; the position angle of the object, such as the angle at which a person stands, the inclination angle of trees, etc., and the size of the object and the picture scale of the entire viewing scene. By identifying the characteristics, the position information and the depth information of the object, composition can be better performed, so that a composition picture is more reasonable and attractive.
In other embodiments, the composition rules include: a subject patterning method and/or a matching patterning method; the main body mapping method is that after a main body object is determined, the main body object is placed at a target position according to the recognition result of the main body object and a conventional mapping rule is adopted to determine a target mapping range; and the matching and mapping method is to match the recognition result of the first viewing scene with a photo database, match a target photo with the most similar result, and determine a target viewing range according to the target photo.
The main body composition method is to determine a main picture, the view range of the whole picture is adjusted aiming at the main body, the adjustment method adopts a conventional composition rule, for example, when a person is identified to exist in the picture and only the upper body of the person is in the picture, the person can be placed on a symmetrical axis of the picture by taking the person as the main body and the neck of the person as the center, and at the moment, the target view range can be determined by adjusting the view range of the picture and enabling the person to be located at a corresponding position in the view picture. The matching and mapping method is to identify all information in a picture, input the identification result into a photo database, store a great amount of excellent photos and content information corresponding to each photo in the photo database, match a target photo with the most similar result from the photo database, determine a target view range according to the target photo, and map the composition according to the excellent photo, so that the composition result and the excellent photo can be guaranteed to achieve similar effects, and even a map repairing suggestion can be provided for a user according to the parameters of the excellent photo.
In other embodiments, the conventional patterning rule comprises: at least one of a trisection pattern, a symmetrical pattern, a frame pattern, a guideline pattern, a diagonal pattern, and a golden triangle pattern. The composition rule is a composition rule which is used more daily, and the content included in the conventional composition rule is continuously improved along with the improvement of the photographing method, so that the conventional composition rule proposed above is also in dynamic change.

When composition is carried out in a first viewing scene, a plurality of target viewing ranges meeting composition rules can be obtained sometimes, the first viewing scene can be displayed on a photographing preview interface in a suspension mode at the moment, a user can select a photo meeting own idea, the user can select one photo or a plurality of photos, when the user selects a plurality of photos, a guide identifier can guide the user to take a photo according to the selection sequence of the user or the moving shortest distance, a guide identifier corresponding to the next target viewing range is displayed, and the user is guided to finish photographing in sequence.
In other embodiments, the photographing method provided by the present invention further includes a self-selection mode, and when the self-selection mode is started, the first view-finding scene is displayed in a suspended manner on the photographing preview interface of the second camera, composition is performed again according to a selection result of the user, and a target view-finding range is determined.
When the user starts the self-selection mode, the first view-finding scene is displayed on the photographing preview interface in a suspension mode, the user specifies a subject object, a photographing range and the like according to own requirements at the moment, and after a selection result of the user is obtained, composition is re-performed according to the selection result of the user, and a target view-finding range is determined.
In other embodiments, the guide mark comprises a guide arrow for indicating the moving direction of the second camera and a range indication box for indicating the limit of the target viewing range.
Referring to fig. 5, fig. 5 is a schematic diagram of a photo preview interface including a guide identifier provided in this embodiment, in fig. 5, the guide identifier includes a guide arrow 202 and a range indication frame 203, where the range indication frame 203 is not completely shown, the guide arrow 202 is used to indicate a moving direction of the second camera, an arrow of the arrow 202 points to a diagonal direction which is generally the range indication frame 203, the range indication frame 203 is used to indicate a boundary of a target viewing range, and after the range indication frame 203 is completely moved into the photo preview interface, the photo preview interface is adjusted according to a display range of the range indication frame 203, so that the photo preview interface only displays the viewing range in the range indication frame 203.
In some embodiments, when the viewing range of the first viewing scene is greater than the viewing range of the second viewing scene, the limit of the target viewing range is determined according to the viewing range of the second viewing scene, so that the limit of the target viewing range is the same as the viewing range of the second viewing scene.
Without limitation, the boundary of the target view range determined according to the composition rule may be any ratio, but in practical applications, a user needs to take a picture of a specific ratio, and the boundary of the target view range to be constructed needs to be determined according to the view range of the second view scene, for example, the user sets the view ratio of the second view scene of the second camera to be 1:1, and the constructed target view range should be constructed at 1: 1.
It should be noted that, in general, the shooting effect of the second camera is better than that of the first camera, or the shooting effect of the second camera on the target viewing range is better than that of the first camera, for example, the first camera is an ultra-wide-angle camera, the second camera is a wide-angle camera, and when the wide-angle camera is used to shoot a partial area in the viewing scene of the ultra-wide-angle camera, the image quality of the obtained picture is obviously better than that of the corresponding area of the picture shot by the ultra-wide-angle camera; of course, in practice, the above-mentioned limitations may not be assumed for any particular purpose.
