  • Imaging apparatus compensating for nonuniformity in detector outputs
    Patent number: 5391873
    Abstract: This invention provides imaging apparatus in which an image is scanned over an array of sensing elements 2, the outputs of which form a plurality of channels. Signal processing means 6 adds a noise signal to at least some of the channels to more closely match the signal to noise ratio of the channels and reduce linear noise structures, to which the eyebrain is particularly sensitive, in the output signal 10 of the processing means.
