Sub-pixel Point Spread function Estimation for Fully Digital Auto-Focusing System
완전디지털 자동초점 시스템 구현을 위한 부화소단위 점확산함수 추정
Abstract
In this paper we propose a sub-pixel point spread function (PSF) estimation method for a fully digital auto-focusing system. We assume that the amount of out-of-focus is the same along the concentric circle. In order to estimate the accurate PSF, sub-pixel information is considered in the proposed PSF estimation procedure. The feasibility of the proposed algorithm is experimentally demonstrated.
