Tardive dyskinesia is an involuntary movement appeared around the mouth mainly caused by long-term administration such as antipsychotic agents for schizophrenia patients. In this paper, a face expression measurement system is proposed in order to evaluate the early tardive dyskinesia objectively. The proposed measurement system includes a non-invasive face expression measurement function using moving images from a camera. The proposed system was applied to a schizophrenia patient observed tardive dyskinesia, and the results show the possibilities for automatic extraction of a quantitative index by frequency analysis of the measurement of face expression variation.
