7.14.1.1 Bayer Color Filter Alignment
All color camera models have sensors equipped with a Bayer filter. The alignment of the filter to the
sensor’s pixels varies with camera model (see Table 53).
Bayer BG alignment, for example, means that pixel one and pixel two of the first line in each image
transmitted will be blue and green respectively. And for the second line transmitted, pixel one and
pixel two will be green and red respectively. Since the pattern of a Bayer filter and its alignment on
the sensor (physical alignment) are fixed, you can use this information to determine the color of all
of the other pixels in the image (effective alignment). For some camera models (see below) the
effective Bayer filter alignment in the image differs from the physical alignment on the sensor when
Reverse X or Reverse Y or enabled. However, these differences are systematic (see Section 7.11
on page 260). The PixelColorFilter parameter indicates the effective alignment of the Bayer filter.
