8.10. Bayer color interpolation (Command : BCIC) (Only for AB-201CL)
This function is available only for AB-201CL. The AB-201CL uses a CCD with an RGB Bayer
pattern. If the Bayer color interpolation is not used, the following RAW data can be
output.

The RAW data contains only luminance information for each color and outputs as a
monochrome signal. The Bayer color interpolation can complement lacking color
information on each pixel and output RGB color data as the result. Color interpolation
compensates for the lack of color information by using information from adjacent pixels.
The following is the concept drawing for the color interpolation process.
