• abstract: This paper presents an online deblurring (ODB) algorithm for time delay integration (TDI) CMOS image sensor (CIS) used in small remote imaging systems, where image quality is degraded due to vibration caused by different factors. The ODB algorithm can detect and compensate the image shift so as to produce sharp TDI images. A 256×8-pixel prototype chip was fabricated using a 0.18μm CIS technology, which contains 8 TDI stages, column-parallel TDI accumulation and online deblurring circuits. The 4-transistor active pixel sensor (4T-APS) is applied, with the pixel size of 6.5μm×6.5μm and the fill factor of 28%.
