8.18 Bayer Color Processing

Bayer color processing is applicable to color models only.
A Bayer tile pattern color filter array captures the intensity red, green or blue in each pixel on the sensor. The image
below is an example of a Bayer tile pattern.
To determine the actual pattern on your camera, query the Pixel Color Filter GenICam feature.
In order to produce color (e.g. RGB, YUV) and greyscale (e.g. Y8, Y16) images, color models perform on-board
processing of the Bayer tile pattern output produced by the sensor.
Conversion from RGB to YUV uses the following formula:
To convert the Bayer tile pattern to greyscale, the camera adds the value for each of the RGB components in the
color processed pixel to produce a single greyscale (Y) value for that pixel, as follows:

Accessing Raw Bayer Data
The actual physical arrangement of the red, green and blue "pixels" for a given camera is determined by the
arrangement of the color filter array on the imaging sensor itself. The format, or order, in which this raw color data
is streamed out, however, depends on the specific camera model and firmware version.
