Zusammenfassung:A device for simulating an expression of a virtual character based on a basis model comprises: a selection unit for selecting any one virtual character among a plurality of previously registered virtual characters; an extraction unit for extracting a feature point for a user's face from a face image; an expression generating unit for generating an expression of the selected virtual character so as to correspond to the extracted feature point based on the constructed basis model; and a rendering unit for rendering by applying the expression of the generated virtual character to the virtual character. Therefore, the present invention is capable of allowing the user's expression to be reflected as the virtual character's expression without awkwardness. 베이시스 모델에 기초하여 가상 캐릭터의 표정을 모사하는 장치는 기등록된 복수의 가상 캐릭터 중 어느 하나의 가상 캐릭터에 대해 선택받는 선택부, 얼굴 이미지로부터 사용자의 얼굴에 대한 특징점을 추출하는 추출부, 기구축된 베이시스 모델에 기초하여 상기 추출된 특징점에 대응하도록 상기 선택받은 가상 캐릭터의 표정을 생성하는 표정 생성부 및 상기 생성된 가상 캐릭터의 표정을 상기 가상 캐릭터에 적용하여 렌더링하는 렌더링부를 포함한다.
