3.11.3 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, except for the Kodak CCD,

which starts with G. The Sony CCD starts with R. The camera timing can be adjusted to start with either

G or R by skipping the very first pixels at each line. Most 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 will be exactly the same. Please

contact PULNiX for further information regarding CCD manufacturers.

3.11.4 Sync and Data

The individual color data is exactly the same as the pixel data. This means that the timing relationships

of the color cameras are also the same as those of the B/W cameras. For a detailed timing chart, please
