human eye’s resolution and color recognition are highest at green, the CFA contains two greens per each red
and blue.
It is critical for the frame grabber and color interpolation to know where the individual color pixels exist
relative to sync (LDV and FDV) timing.
This requirement makes digital output the preferred choice, because the timing relationships are very accurate

3.2.3 Starting Pixel Configuration
All manufacturers produce identical Bayer CFAs, but there are slight differences between the CCDs produced by
different manufacturers. The first line is generally R and G. The camera timing can be adjusted to start with
either G or R by skipping the very first pixels at each line. The majority of color interpolation software can
select between a variety of pixel relations, such as R/G start or G/R start, as well as G/B start and B/G start.
Once the correct scanning is configured, the rest of the interpolation is exactly the same. Contact JAI, Inc. for
further information regarding CCD manufacturers.
