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 13):
An imaging device comprising:\n a sensor array including a plurality of individual pixels formed in a non-silicon substrate and sensitive to a particular wavelength (\u03bb) of electromagnetic radiation, said pixels having a surface area smaller than a predefined diffraction limited minimum blur of associated optics; and circuitry formed in a silicon substrate, said silicon substrate fixed to said non-silicon substrate, and said 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 others of said pixels within a predetermined area associated with said particular pixel; and a size of said predetermined area relates to said predetermined minimum blur such that at least a portion of every pixel in said predetermined area will fit within a perimeter having a size corresponding to said predetermined minimum blur.
