Abstract:
In one embodiment of the present invention, a method for determining a phase alignment of a Bayer color filter array is provided. A quincunx lattice of the color filter array corresponding to a first color component is determined from an input frame of image data. Elements of the color filter array corresponding to first and second rectangular lattices of the color filter array are selected. Second and third color components corresponding to elements of the first and second rectangular lattices are determined from the sample values in an input frame of image data.
