Abstract
A signal processing-based scheme for acquiring high-resolution pictures with sufficiently high signal-to-noise ratio (SNR) by processing multiple charge-coupled device (CCD) images is presented. The method integrates multiple low-resolution images into a high-resolution image. Compared to a CCD imaging device with equivalent resolution, it may be less sensitive to shot noise which becomes more dominant as the pixel size of an imager is further reduced. Preliminary experiments using a camera model have shown clear improvements in the high frequencies and image details. A strategy to further improve resolution is also described.Keywords
