Claim Text:
1. An imaging system comprising: optics including a limiting aperture and a focal length, said limiting aperture and said focal length defining a diffraction limited minimum blur of the system for electromagnetic radiation of a particular wavelength (λ); a sensor array including a plurality of individual pixels disposed in a focal plane defined by said optics and sensitive to said particular wavelength of electromagnetic radiation, each of said pixels having a surface area smaller than one-ninth ( 1/9) of the surface area of said diffraction limited minimum blur; and a noise suppresser operative to identify false positive noise signals from properly operating ones of said individual pixels by correlating the signal from a particular pixel with at least one other of said pixels within a predetermined area associated with said particular pixel; and wherein a false positive noise signal is a signal from a particular pixel indicative of light incident on said particular pixel when no light is being focused on said particular pixel by said optics.
