Abstract:
An image sensor device formed in an integrated circuit (IC) having a filter device in which filter elements are arranged to provide color symmetry with respect to an optical center of the imaging array of pixels. This color symmetry ensures that any color cross-talk that occurs will be symmetrical with respect to the optical center of the imaging array and will result in a color error that is radial and easily correctable using color interpolation.
