Removal of Glare Caused by Water Droplets

Abstract

View disturbing noise must be removed from images obtained with a camera under adverse weather conditions. In this paper, we present a method for removing glare caused by water droplets, or other foreign objects, adhering to protective glass of an imaging lens. We have designed and implemented an electronically controlled optical shutter array that detects and removes glare. We also present the possibility of applying this technique to remove general glare caused by the imaging lens itself.
