In this embodiment, when the shooting device shoots a target shooting object, a user needs to determine the target shooting object in a shooting picture, so that the shooting device can adjust the quality of the shooting picture according to the requirement of the user on the shooting picture. For example, when a user takes a picture, the user determines that a person in the picture is a main object to be taken, and then adjusts the focal length of the picture according to the definition of the person picture.
Alternatively, the user may actively select the target photographic subject, as shown in fig. 5, and the step S401 of determining the target photographic subject in the photographic image may include:
