An image sensor for capturing a color image is disclosed having a
two-dimensional array having first and second groups of pixels wherein
pixels from the first group of pixels have narrower spectral
photoresponses than pixels from the second group of pixels and wherein
the first group of pixels has individual pixels that have spectral
photoresponses that correspond to a set of at least two colors. Further,
the placement of the first and second groups of pixels defines a pattern
that has a minimal repeating unit including at least twelve pixels. The
minimal repeating unit has a plurality of 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 arranged to permit the reproduction of a captured color image
under different lighting conditions.
