Abstract

The invention provides a focusing method and device for realizing a clear face and a computer device. The focusing method for realizing the clear face comprises the steps of when a camera is focused, carrying out face identification on a to-be-photographed image, and obtaining first position information of a face in a current frame of the to-be-photographed image; before the to-be-photographed image is photographed, obtaining second position information of the face in a next frame after the current frame; judging whether a position of the face is changed or not according to the first position information and the second position information; if the position of the face is changed, resetting a region of interest of the face; and focusing the face according to the region of interest of the face. According to the method, the device and the computer device, the face can be tracked in real time, and after the position of the face deviates from a focusing position, the camera is triggered to carry out refocusing, so the face in the photographed image is relatively clear.

Description

technical field [0001] The present application relates to the technical field, and in particular to a focusing method, device and computer equipment for realizing clear human faces. Background technique [0002] In the existing related technology, after the camera is focused, if the image to be shot does not shake greatly, the camera will not be triggered to refocus. Then, when there is a face in the image to be captured, if the position of the face changes, such as the face moves back and forth, left, right, or shakes, and the entire image to be captured does not change much, the camera will not be triggered to re-start. focus. This leads to a problem. If the position of the face in the image to be captured changes, the camera does not trigger refocusing, but since the face has left the focus position, the face in the captured photo is blurred. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to ...
