| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 94 === With the boosting of number of image sensor’s pixels and the compacter working volume of today’s digital still camera or camera phone, the need for better image quality has soared and drives more newly designed image processing techniques. Image stabilization, one of these newly techniques, plays an essential role in today’s camera design. As its words suggest, image stabilization is a system designed to reduce the amount of image blur due to human’s handshake or even preventing the chances of a blur. Currently, image stabilization can be carried out by optical lens solution or by digital image processing technique.
In this thesis, we propose a digital image stabilization algorithm based on an image composition technique using four source images. By using image processing techniques, we are able to reduce the amount of image blur and compose a sharper image from four source images.
