Abstract
Disclosed is a method and apparatus for multi-face tracking of a face effect, and a computer readable storage medium. The method for multi-face tracking of a face effect comprises steps of: selecting a face effect in response to an effect selection command; selecting a face tracking type of the face effect in response to a face tracking type selection command; generating a face tracking sequence based on the face tracking type; recognizing a face image captured by an image sensor; superimposing the face effect on at least one of the face images according to the face tracking sequence. In the embodiment of the invention, for the face that needs to be tracked as specified by the effect, the number of faces of superimposed faces for the face effect, the superimposition order, and the display duration of the face effect can be arbitrarily set, and different effects can be superimposed on multiple faces, so as to improve the user experience.
