Abstract
A digital imager apparatus uses the differences in absorption length in silicon of light of different wavelengths for color separation. A preferred imaging array is based upon a three-color pixel sensor using a triple-well structure. The array results in elimination of color aliasing by measuring each of the three primary colors (RGB) in each pixel in the same location.
