ABSTRACT:
What is disclosed is method that interpolates missing color components for an original pixel by utilizing color gravities for surrounding blocks of green pixels. A new pixel is output which has complete color information which is a function of the original pixel and interpolated color components. The interpolated pixel is a true representation of both luminance and chrominance information.
