Abstract

This paper introduces motion focus as a complement to conventional camera focusing. We show how a relative shift between the image sensor and lens of a camera offers the ability to focus on specific motion in a scene. Focusing on motion allows the use of a longer exposure time while preventing motion blur of the object of interest. As a result, the object is captured with a significantly improved image quality. We derive a theoretical performance gain and compare it to existing imaging methods. Furthermore, we demonstrate an experimental motion focus implementation using modified off-the-shelf optical image stabilization hardware, which can obtain an effective exposure time extension of a factor of 94.
