An Image Stabilization Technology for Digital Still Camera Based on Blind Deconvolution

Abstract

In this article, we present a new image-stabilization technology for still images based on blind deconvolution and introduce it to a consumer digital still camera. This technology consists of three features: (1) double-exposure-based PSF detection, (2) efficient image deblurring filter, and (3) edge-based ringing reduction. Without deteriorating the deblurring performance, the new technology allows us to reduce processing time and ringing artifacts, both of which are common problems in image deconvolution.
