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 16):
In an imaging system having optics and a pixelated imager, said pixelated imager including pixels each small enough to allow a diffraction limited minimum blur of said optics to impinge on a first number of said pixels simultaneously, a method of processing image data, said method comprising:\n generating a first image data set from multiple frames of image data acquired from said pixelated imager over time; generating a second image data set from a single frame of image data from said pixelated imager; subtracting said first image data set from said second image data set on a pixel-by-pixel basis to obtain a remainder value associated with each particular pixel; comparing each said remainder value to a predetermined threshold value to determine whether each said remainder value exceeds said predetermined threshold value; determining, for each particular pixel associated with one of said remainder values that exceeds said predetermined threshold value, whether each of a second number of pixels within a predefined area associated with said particular pixel is also associated with a remainder value that exceeds said predetermined threshold value; associating a value indicative of a verified signal with said particular pixel if at least a predetermined number of said remainder values associated with said second number of other pixels exceed said predetermined threshold value; and associating a value indicative of a false positive noise signal with said particular pixel if at least said predetermined number of said remainder values associated with said second number of pixels do not exceed said predetermined threshold value; and wherein said second number of pixels is based at least in part on said first number of said pixels; and 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.
