A facial image processing method for determining an eyebrow raising action of a user, comprising: separately performing feature extraction on a plurality of continuously captured frames of facial images of the user, and obtaining a plurality of facial feature points in each frame of the plurality of frames of facial images, wherein the facial feature points comprise eyebrow feature points and eye feature points, and wherein the eyebrow feature points comprise eyebrow tails for each eyebrow, and the eye feature points comprise outer eye corners that are on same sides of the eyebrow tails; calculating distances between eyebrow feature points and eye feature points in each frame, which comprises calculating second eyebrow-eye spacings between each eyebrow tail position (21, 29) and the outer eye corner position (37, 45) on the same side; calculating feature parameters indicating change amounts of the calculated distances between the plurality of frames of facial images; and determining, if the change amounts of the calculated distances occurring between the plurality of frames of continuously captured facial images satisfy a preset condition associated with the detection of the eyebrow raising action, characterized in that the eye feature points further comprise a lower edge center position of each eye, wherein the method further comprises: the calculating distances between eyebrow feature points and eye feature points in each frame further comprises: calculating first eyebrow-eye spacings between each eyebrow tail position and the lower edge center position of the eye that is on same side of the eyebrow; and the determining, if the change amounts of the calculated distances occurring between the plurality of frames of continuously captured facial images satisfy a preset condition associated with the detection of the eyebrow raising action comprises: determining, if a difference between a ratio of one of the first eyebrow-eye spacings to one of the second eyebrow-eye spacings in a first frame of the plurality of frames of facial images and a ratio of the corresponding one of first eyebrow-eye spacings to the corresponding one of second eyebrow-eye spacings in a second frame of the plurality of frames of facial images exceeds a preset threshold. separately performing feature extraction on a plurality of continuously captured frames of facial images of the user, and obtaining a plurality of facial feature points in each frame of the plurality of frames of facial images, wherein the facial feature points comprise eyebrow feature points and eye feature points, and wherein the eyebrow feature points comprise eyebrow tails for each eyebrow, and the eye feature points comprise outer eye corners that are on same sides of the eyebrow tails;
