Operation

3.9.3Starting 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 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 lines. 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 will be exactly the same. Please contact JAI PULNiX for further information regarding CCD manufacturers.

3.9.4Sync 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 of the B/W cameras.

For a detailed timing chart, please refer to each B/W camera’s data sheet and manual.

If the frame grabber has a standard B/W configuration file, then AccuPiXEL color cameras can use that configuration file to operate. The configuration file may vary, depending on whether the output is standard (RS-644) or Camera Link. Please consult JAI PULNiX, or your frame grabber supplier for compatibility information.
