Abstract:
An over sampled image sensor in which the pixel size is small enough to provide spatial oversampling of the minimum blur size of the sensor optics is disclosed. Image processing to detect targets below the typical limit of 6× the temporal noise floor is also disclosed. The apparatus is useful in detecting dimmer targets and targets at a longer range from the sensors. The inventions exploits signal processing, which allows spatial temporal filtering of the superpixel image in such manner that the Noise Equivalent Power is reduced by a means of Superpixel Filtering and Pooling, which increases the sensitivity far beyond a non-oversampled imager. Overall visual acuity is improved due to the ability to detect dimmer targets, provide better resolution of low intensity targets, and improvements in false alarm rejection.

Claim (Index 1):
An imaging system comprising:\n 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 (\u03bb); 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, said pixels being small enough to allow said diffraction limited minimum blur to impinge on a first number of said pixels simultaneously, said first number being an integer greater than one (1); and circuitry connected to receive image data from said sensor array, said image data including a plurality of signals each corresponding to one of said plurality of individual pixels and indicative of an amount of electromagnetic radiation impinging on said corresponding one of said plurality of individual pixels of said sensor array; and wherein said circuitry is operative to identify false positive noise signals from properly operating ones of said individual pixels by correlating said signal corresponding to a particular pixel with a second number of others of said pixels within a predetermined area associated with said particular pixel, said second number being an integer greater than or equal to one (1); and said second number of said pixels is based at least in part on said first number of said pixels.
