Color Imaging Based on Computational Imaging and Narrow Band Absorption Color Filter Array
Researchers at the University of Arizona have created a novel color filter array (CFA) that allows much more light to reach a detector than conventional CFAs. The novel arrangement of filters with respect to wavelength cutoffs allows for crisp digital imaging with half the ambient light level required by currently known CFAs. The advantage is especially...
