Abstract
A device, system and method of image processing and compression are preferably used with second generation infrared (IR) detector arrays where the pixel size is less than the optical blur of the system. Raw input pixels are compressed such that output pixels are more closely matched to the optical blur of the system. Further, the number of output pixels are compressed from a greater number of input pixels, based upon a selected input-to-output compression ratio. The ratio is not constrained to be of an integer value. The compression takes place using a plurality of neighborhood processors, each corresponding to a different output pixel type. Each neighborhood processor contains a plurality of different predetermined weighed fractions of input pixel data and are used to produce compressed output pixel data, based upon the selected input-to-output compression ratio and the output pixel type, for real-time processing.
