Motion-invariant coding using a programmable aperture camera

Abstract

A moving object or camera causes motion blur in a conventional photograph, which is a fundamental problem of a camera. In this research, we propose to code a motion-invariant blur using a programmable aperture camera. The camera can realizes virtual camera motion by translating the opening, and as a result, we obtain a coded image in which motion blur is invariant with the object velocity. Thereby, we recover motion blurs without estimation of the motion blur kernels or knowledge of the object speeds. We model the projection of the programmable aperture camera, and also demonstrate that our proposed coding works for a prototype camera. © 2013 Springer-Verlag.
