スウィングとウォーブリング撮像を用いたCCDイメージセンサの高解像度化方式についての解析

抄録

High resolution solid-state image sensors are strongly required for many imaging systems. Double resolution enhancement without increasing CCD pixel density was achieved by CCD-chip swing operation. Furthermore, a wobbling operation enlarging a pixel aperture is capable to suppress effectively a field flicker. We analytically derive that a triangular wave swing and wobbling operation is superior to a rectangular wave mode for higher resolution imaging in considering aliasing. Also, an optimum condition for the triangular wave swing and wobbling operation is derived.
