CYGM filter
In digital photography, the CYGM filter is an alternative color filter array to the Bayer filter (GRGB). It similarly uses a mosaic of pixel filters, of cyan, yellow, green and magenta, and so also requires demosaicing to produce a full-color image.
Overview
CYGM gives more accurate
While the CYGM filter found widespread adoption in the early years of digital photography, at the time a rival of the now standard Bayer filter, it is now considered obsolete. CCDs that used it include the 3 megapixel Sony ICX252AK and ICS252AKF (which sampled in October 1999.[3])
CCDs with a CYGM color filter array were initially adopted by both Canon and Nikon when these companies transitioned from film photography to digital. Many
Additionally, Panasonic also used CCDs with a CYGM filter array. These were internally referred to as 'complementary color filters'. [6]
