Claim 0:
1. A face image displaying method, comprising:
displaying dynamically a face mask sequence in accordance with a preset motion mode at a preset relative position of a face of an object, wherein the face mask sequence comprises a plurality of face masks corresponding to the face of the object; and
in response to a trigger instruction acting on a target face mask, fusing the target face mask to the face of the object for display, wherein the target face mask is any face mask of the face mask sequence,
wherein the displaying dynamically the face mask sequence in accordance with the preset motion mode at the preset relative position of the face of the object comprises:
with the face of the object as a center and an overhead direction of the face of the object as a central axis, displaying dynamically the face mask sequence in a rotation motion mode, wherein the face masks of the face mask sequence are arranged in a preset circumferential direction,

wherein the displaying dynamically the face mask sequence in the rotation motion mode comprises:
acquiring a characteristic parameter of a target part on the face of the object; and
determining a rotation speed of the rotation motion according to the characteristic parameter, and displaying dynamically the face mask sequence in accordance with the rotation speed, and

wherein the acquiring the characteristic parameter of the target part on the face of the object comprises:
acquiring a mouth characteristic parameter and an eye characteristic parameter of the face of the object, wherein the mouth characteristic parameter comprises a key point coordinate of an upper lip and a key point coordinate of a lower lip, and the eye characteristic parameter comprises a key point coordinate of a left eye and a key point coordinate of a right eye;
determining a first coordinate difference in a first direction according to the key point coordinate of the upper lip and the key point coordinate of the lower lip, and determining a second coordinate difference in a second direction according to the key point coordinate of the left eye and the key point coordinate of the right eye; and
determining the characteristic parameter according to a ratio of the first coordinate difference to the second coordinate difference.
