초록

피사계 심도 효과는 초점이 맞은 부분은 선명하게 나타나고, 그렇지 않은 부분은 흐리게 나타나는 효과를 뜻한다. 본 논문은 실시간 렌더링 환경에서 사용 가능한, 표준 정규 분포를 기반으로 한 샘플링 범위 계산 및 레이어 색상의 알파 블렌딩을 이용한 역방향 매핑 방식 기반의 피사계 심도 효과 구현 방법에 대해 제안한다. 효과 구현을 위해 착란원 크기 계산 방법, 착란원 크기의 표준 정규 분포를 통한 샘플링 영역 설정, 다층 레이어의 알파 블렌딩을 통한 색상 결정 및 디노이징을 통한 이미지 품질 향상 방법에 대해 서술한다.

This paper proposes on the implementation method of depth of field effect based on backward mapping method available in real-time rendering enviroment using calculation of sampling range based on standard normal distribution and alpha blending of color of layers. To implement the effect, this paper describe how to calculate radius of circle of confusion, establish sampling radius using circle of confusion, and determine color through alpha blending of the multiple layer and denoising.
