9.2.3 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.
