CYGM filter

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.

CYGM gives more accurate luminance information than the Bayer filter, hence a wider dynamic range, but at the expense of color accuracy.

Under the conventional trichromatic theory, a 'green' measurement is taken by placing a color filter which absorbs 'red' and 'blue' in front of the light sensor.

[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.

Whereas Canon adopted the now standard Bayer filter across its entire range when it introduced the DSLR, Nikon continued to produce and sell a range of mid-range enthusiast digital cameras using CYGM sensors for a period of approximately 5 years.
