1. A method for controlling eyes in a face model and performed by a hardware device, comprising:
acquiring a face image and the face model;
determining a human eye open amplitude and a reference distance in the face image;
calculating a relative amplitude of the human eye open amplitude relative to the reference distance;
acquiring a maximum relative amplitude;
calculating a human eye close weight in the face image based on the relative amplitude and the maximum relative amplitude; and
controlling an eye in the face model based on the human eye close weight.
