Abstract
The disclosure discloses a focusing method, device, and computer apparatus for realizing a clear human face. The focusing method includes: acquiring first position information of a human face in a current frame of an image to be captured by performing face recognition on the image, after a camera finishing focusing; acquiring second position information of the human face in a next frame, before shooting the image; determining whether a position of the human face changes, based on the first and second position information; resetting an ROI of the human face when it changes; and refocusing on the human face based on the ROI. The disclosure can track the human face in real-time, and trigger the camera to refocus after the human face deviates from a previous focusing position, thereby to make the human face in the captured photograph clear.
