Sony today announced the world&s first practical consumer (home) use of CCD
with 4-color (Red[R> , Green[G] , Blue[B]+ Emerald[E] ) filters, together with a new image processor corresponding to the 4-color filter. By this technology, the color reproduction error is halved compared to Sony&s conventional 3-primary-color filter CCD and, expression of images closer to the natural sight perception of the human eye is achieved under various shooting conditions.
