| Summary: | 碩士 === 國立交通大學 === 精密與自動化工程學程碩士班 === 91 === The purpose of this study is to develop a method for increasing the resolution of an image system with low cost. This method can generate a very slight shift of image, the optical path is varied by rotation of a pair of optical wedges. The very slight shift is equivalent to reducing pixel size. The more pixels there are, the higher the resolution is. This study installs a pair of optical wedges in front of a low resolution CCD camera lens. Several images of different imaging positions are taken. Digital image processing yields a high quality image. The resolution of this system can achieve 1280 x 960 pixels.
