Abstract: Disclosed are a system and a method for producing a stereoscopic image with an image moving area filling function. The system for producing a stereoscopic image according to an embodiment of the present invention comprises a moving area detection unit for checking a moving area of an object moving in an image, detecting/tracking changes in the moving area by distinguishing the foreground and the background of the moving area, and providing the result information; a filling error processing unit for filling a gap detected by the moving area detection unit, and correcting the filled area; and a stereoscopic image visualization unit for visualizing the stereoscopic image corrected by the filling error processing unit. As a result, a gap due to object movement in a stereoscopic image which may be created by generating a stereoscopic image or changing a sense of depth in a stereoscopic image can be filled, and time for producing a stereoscopic image can be reduced.

Abstract: 본 발명은 카메라 이동에 따른 효과적인 렌더링 데이터 처리 기술에 관한 것으로, 종래의 방법은 카메라가 이동하면 이동한 카메라 뷰에 따른 데이터를 새로 구성하여 카메라의 이동이 있을 때마다 데이터를 새로 생성하므로 리소스의 낭비가 있었다. 이에 본 발명은, 렌더링 시 카메라 뷰에 대해 생성된 딥 렌더 버퍼에 저장된 데이터를 카메라 매트릭스를 이용하여 원래의 값으로 복원하고 이동된 카메라 값을 이용하여 새로운 렌더링 데이터를 구성하는 것을 특징으로 한다. 본 발명에 의하면, 카메라 이동에 대한 딥 렌더 버퍼를 재구성할 수 있으며, 이는 피사계 심도(DOF)와 같이 카메라의 이동에 대한 데이터를 이용하는 경우에 효과적으로 사용될 수 있다.
