Patent ID: 7019777

Claim:
An imaging system having spatial resolution enhancement comprising: (a) a multispectral imager having four synchronized monochromatic camera for providing multispectral bands of images; (b) said multispectral image comprising a narrow band interference filter in front of each of said four synchronized monochomatic cameras, each interference filter being different comprising a spectral band within the spectral ranges covering blue, green, red, and near infrared; (c) a computer system connected to an output of each of said four sysnchronized cameras of said multispectral images for receiving said multispectral bands of spectral images and performing resolution enhancement; (d) means within said computer system for resampling-up each of said multispectral bands of spectral images using neighbor average interpolation; (e) means for storing said resampled-up multispectral bands of images for digital processing; and (f) means for performing fine pitch shifting on said multispectral band-to-band pixel registration of said resampled-up images to obtain more accurate band-to-band, registration.
