Abstract
A camera comprises a sensor such as a CCD or ICCD for receiving radiation representative of a scene, a filter such as an arrangement of parallel neutral density stripes, arranged to attenuate the radiation reaching the sensor, and decoding electronics such as comb filters which decode the encoded video output of the sensor, to produce a compressed video image, from which the pattern of the filter has been removed.
