DEMOSAICING FOR DIGITAL IMAGING DEVICE USING PERCEPTUALLY UNIFORM COLOR SPACE

A digital camera is provided having a lens for focusing light from an image through a RGB mosaiced filter on to a solid state photosensor array containing a matrix of CCDs. The CCDs provide a single-channel mosaiced image output. A demosaicing process includes a first color transformation after separation for determining luminance and a luminance interpolation for interpolation of missing luminance components. The demosaicing process further includes a second color transformation for obtaining chrominance components. A chrominance interpolation for interpolation of missing chrominance components and an inverse color transformation transforms the components into the RGB space for combination into an image output.
