Abstract
A system for capturing a color image, includes a two-dimensional array having first and second groups of pixels, pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors; the placement of the first and second groups of pixels defining a pattern that has a minimal repeating unit including at least twelve pixels, and a plurality of non-overlapping cells wherein each cell has at least two pixels representing a specific color selected from the first group of pixels and a plurality of pixels selected from the second group of pixels; a structure for combining pixels of like color from at least two of the plurality of cells within the minimal repeating unit.
