A focusing method for realizing a clear human face, comprising: 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 to be captured in response to a camera finishing focusing; acquiring second position information of the human face in a next frame after the current frame, before shooting the image to be captured; determining whether a distance between the first position information and the second position information is greater than a predetermined threshold; the method being characterized by further comprising: if it is determined that the distance between the first position information and the second position information is greater than the predetermined threshold, acquiring third position information of the human face in another next frame which is after a predetermined number of frames; determining, according to the third position information and the first position information, whether the position of the human face returns to the original position indicated by the first position information after waiting for the time passed during the predetermined number of frames; if it is determined that the human face does not return to the original position, resetting a region of interest of the human face according to the third position information; and refocusing on the human face based on the ROI; wherein the camera is not triggered to refocus, if it is determined that the distance between the first position information and the second position information is not greater than the predetermined threshold, or if it is determined that the human face returns to the original position indicated by the first position information. 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 to be captured in response to a camera finishing focusing; acquiring second position information of the human face in a next frame after the current frame, before shooting the image to be captured; determining whether a distance between the first position information and the second position information is greater than a predetermined threshold; the method being characterized by further comprising: if it is determined that the distance between the first position information and the second position information is greater than the predetermined threshold, acquiring third position information of the human face in another next frame which is after a predetermined number of frames; determining, according to the third position information and the first position information, whether the position of the human face returns to the original position indicated by the first position information after waiting for the time passed during the predetermined number of frames; if it is determined that the human face does not return to the original position, resetting a region of interest of the human face according to the third position information; and refocusing on the human face based on the ROI; if it is determined that the distance between the first position information and the second position information is greater than the predetermined threshold, acquiring third position information of the human face in another next frame which is after a predetermined number of frames; determining, according to the third position information and the first position information, whether the position of the human face returns to the original position indicated by the first position information after waiting for the time passed during the predetermined number of frames; if it is determined that the human face does not return to the original position, resetting a region of interest of the human face according to the third position information; and refocusing on the human face based on the ROI; wherein the camera is not triggered to refocus, if it is determined that the distance between the first position information and the second position information is not greater than the predetermined threshold, or if it is determined that the human face returns to the original position indicated by the first position information.
