Abstract Charge-Coupled Device (CCD) is one of the widely-used optical
sensing device technologies for various digital imaging systems such as digi-
tal cameras, digital camcorders and digital x-ray imaging systems. Pixels on
a CCD may suffer from defective or faulty pixels due to numerous causes such
as imperfect fabrication, excessive exposure to light, radiation and sensing el-
ement aging to mention a few. As the use of high-resolution CCDs increase,
defect and fault tolerance of such devices demands immediate attention. In this
context, this paper proposes a testing and repair technique for defects/faults
