| Abstract: | This paper presents the principle to inhance the spatial 2-D resolution of CCD camera by means of Swing of the imager and analyses the factors effecting on its spacial 2-D resolution and the possibly available limitation of maximum resolution. The paper also reports on image signal processing for 2-D high definition picture and the hanging-up piezoelectric bimorph construct designed to improve both horizontal and vertical resolution respectively by one time. The regenerated signal can be Compatible with current TV mode. |
