Abstract
A subject detecting method, including: acquiring a current-frame image, and detecting whether the current-frame image has a focus frame triggered by a user; in response to the current-frame image having the focus frame, determining a target subject of the current-frame image based on an image in the focus frame; and in response to the current-frame image not having the focus frame, acquiring a tracking frame of a previous-frame image previous to the current-frame image, determining a first center weight map based on the tracking frame, and obtaining the target subject of the current-frame image by traversing the current-frame image based on the first center weight map. Weight values of the first center weight map are gradually reduced from a center to each edge thereof, and the tracking frame shows a region where the target subject is located in the previous-frame image.
