Abstract

In this paper, we propose an out-of-focus blur estimation using isotropic step responses and its application to image restoration. The proposed algorithm can make in-focused image by using only digital image processing techniques, and it required neither infrared light or ultrasound nor focusing lens assembly operated by electrically powered movement of focusing lens.
