Abstract
An auxiliary focusing method, device and system. When a user uses an image capturer to photograph a target scene, an auxiliary focus image can be generated based on depth information of objects in the target scene, and the auxiliary focus image can visually display the depth distribution of the objects in the target scene and a corresponding position of a focus point of the image capturer in the target scene, so that the user can intuitively understand the current position of the focus point from the auxiliary focus image and adjust the position of the focus point according to the depth distribution of the objects, so that an object of interest to the user can be clearly imaged.
