Assignee: BEIJING BYTEDANCE NETWORK TECHNOLOGY CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A face image displaying apparatus, comprising:
at least one processor and a memory;
wherein the memory stores computer-executable instructions; and the at least one processor executes the computer-executable instructions stored in the memory to:
display 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;
acquire a trigger instruction acting on a target face mask;
fuse the target face mask to the face of the object, wherein the target face mask is any face mask of the face mask sequence; and
display the face of the object to which the target face mask is fused,
wherein the at least one processor further executes the computer-executable instructions stored in the memory to:
acquire 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;
determine 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;
determine a characteristic parameter of a target part on the face of the object according to a ratio of the first coordinate difference to the second coordinate difference; and
determine a rotation speed of a rotation motion according to the characteristic parameter, and 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 the rotation motion mode in accordance with the rotation speed, wherein the face masks of the face mask sequence are arranged in a preset circumferential direction.
