Bayer CFA Decoding Methods

Various Bayer CFA decoding methods are defined to transform the raw Bayer CFA data stream issued by the camera into an RGB color data stream

CFA decoding method 1

Applies to the following firmware variants of Closed1628 Grablink Duo, 1633 Coaxlink Quad G3, 1633-LH Coaxlink Quad G3 LH, 1635 Coaxlink Quad G3 DF, 3602 Coaxlink Octo, 3603 Coaxlink Quad CXP-12, 3603-4 Coaxlink Quad CXP-12, 3623 Coaxlink Quad CXP-12 Value, 3624 Coaxlink Quad CXP-12 DF and 3625 Coaxlink QSFP+.
