Further, after identifying whether the person, the article, or the animal is present, it is possible to specifically detect whether the person, the article, or the animal is the entire subject, a certain portion of the subject, or a part of the certain portion of the subject. Taking an example that the shooting object is a human, a certain part in the shooting object can be a human face, an arm, two legs and the like, and a part of the certain part in the shooting object can be a half human face, a half palm and the like.

It is understood that, in order to accurately detect whether a part of a photographic subject is complete, a trained target part recognition model may be used to perform recognition of the subject, and in an alternative embodiment, the detecting whether the target part of the photographic subject is complete may include: inputting the preview image into a target part recognition model for processing, and judging whether the target part is complete or not; the result of whether the target part is complete is used for indicating whether all the target parts of each shot object are included in the preview image, the object recognition model is obtained by training through a sample data set, the sample data set comprises a first sample image and a second sample image, the first sample image comprises the complete target parts of each shot object, and the second sample image comprises the incomplete target parts of each shot object. Taking an example of a shooting object as an example, when training of an object recognition model is performed, the first sample image in the sample data set may be an image of a human face, a pair of hands, one leg, and the like, and the second sample image may be an image of only a part of a human face (a left face, a right face, a forehead, a chin, and the like), a part of a hand (a half palm, 4 fingers, and the like), and the like.

In an optional embodiment, the detecting whether the target portion of the photographic subject is complete may include: inputting the preview image into a target part recognition model for processing to obtain a result of whether the target part is complete or not; the result of whether the target part is complete is used for indicating whether the preview image includes the target part of each shot object, the object recognition model is obtained by training through a sample data set, the sample data set includes a first sample image and a second sample image, the first sample image includes the complete target part of each shot object, and the second sample image includes other parts of each shot object except the target part or other parts of a certain area of each shot object except the target part.
