Patent ID: 7688368

Claim:
An image sensor for capturing a color image, comprising: a) a two-dimensional array having first and second groups of pixels, arranged in rows and columns, 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 pixels that have spectral photoresponses that correspond to a set of at least two colors; b) the placement of the first and second groups of pixels defining a pattern that has a minimal repeating unit including at least six pixels, so that at least some rows or columns of the minimal repeating unit are composed only of pixels from the second group and some rows or columns of the minimal repeating unit are composed only of pixels from the first group, wherein the rows or columns that are composed only of pixels from the first group are composed of at most two colors of pixels from the first group; and c) the minimal repeating unit having: P P A B P C wherein P represents pixels of the second group, A represents pixels of a first color of pixels of the first group, B represents pixels of a second color of pixels of the first group, and C represents pixels of a third color of pixels of the first group.
