FOCUSING METHOD, APPARATUS AND DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM

Disclosed are a focusing method, apparatus and device, and a computer-readable storage medium. The method comprises: in a photographing interface for photographing a target object, when a focusing prompt control is displayed, receiving a first touch-control movement operation that acts on a first area of a display screen, wherein the first area is any area in the photographing interface, the included angle between a movement direction of the first touch-control movement operation and a first direction is less than or equal to a pre-set angle, and the first direction is a direction parallel to an axial direction of the arrangement of the focusing prompt control; in response to the first touch-control movement operation, determining a focusing position mapped to the focusing prompt control; on the basis of the focusing position, determining a corresponding focusing parameter; and on the basis of the focusing parameter, adjusting a focal length for photographing the target object. By means of the method, a focusing range can be increased, a focusing limitation can be alleviated, and the human-machine interaction performance can be improved.
