Abstract:
A demosaicing method comprising the steps of:receiving patterned mosaiced images in a plurality of colors; and demosaicing icing including the steps of: separating the patterned mosaiced images into a plurality of single color planes; a first color transformation on the plurality of single color planes to determine luminance; a luminance interpolation on the output of said first color transformation; a second color transformation on the output or said luminance interpolation to determine chrominance; a chrominance interpolation on the output of said second color transformation; an inverse color transformation on the output of said chrominance interpolation to provide single color images; and combining the output of said inverse color transformation into a demosaiced color images, wherein the luminance interpolation makes an L interpolation that: YL&af;(i,j)=&Sum;m=-66&it;â€ƒ&it;&Sum;n=-66&it;F1&af;(m,n)Ã—XL&af;(i+m,j+n)/â€‰2&it;15Ã—2where: YL is a mosaiced output of the L interpolation, F1 represents a filter, and XL represents a luminance output.
