Abstract: Embodiments are disclosed of a color filter array including a plurality of tiled minimal repeating units. Each minimal repeating unit comprises a set of individual filters grouped into an array of M rows by N columns, wherein each set of individual filters includes a plurality of individual filters having at least first, second, third, and fourth spectral photoresponses. If M equals N, at least two directions within each minimal repeating unit include individual filters having all the spectral photoresponses, the at least two directions being selected from a set of directions consisting of row, column, major diagonal and minor diagonal. And if M≠N at least two directions within each of one or more N×N or M×M cells within the minimal repeating unit include individual filters having all the spectral photoresponses, the at least two directions being selected from a set of directions consisting of row, column, major diagonal and minor diagonal of each cell.
