Bayer color interpolation (Only for EL-2800C)

This function is available only for EL-2800C-GE2. The EL-2800C-GE2 uses a CCD with an RGB Bayer
pattern. If in-camera 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 function can complement lacking color information on each
pixel and output RGB or YUV 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. It is invoked when one of the interpolated pixel formats
(RGB or YUV) is selected.
