ne where R,G, and B pixels (sensors of a particular component) are interleaved as follows:
The output RGB components of a pixel are interpolated from 1, 2, or 4 neighbors of the pixel having the same color. There are several modifications of the above pattern that can be achieved by shifting the pattern one pixel left and/or one pixel up. The two letters C and C in the conversion constants CV_Bayer C1C2 2BGR and CV_Bayer C1C2 2RGB indicate the particular pattern type. These are components from the second row, second and third columns, respectively. For example, the above pattern has a very popular "BG" type.
