6.3.1 Color Filter Alignment on the Aviator
The alignment of the Bayer filter to the pixels in the images acquired by color versions of the camera
is Bayer GR.
Bayer GR alignment means that the first and second pixel of the first line in each image transmitted
will be green and red respectively. And for the second line transmitted, the first pixel and the second
pixel will be blue and green respectively. Since the pattern of the Bayer filter is fixed, you can use
this information to determine the color of all of the other pixels in the image.
Since the area of interest (AOI) width, and height can only be changed in increments of 4 on color
cameras, the alignment of the Bayer filter to the pixels in the transmitted images will stay the same
regardless of the size of the AOI.
When either the reverse X feature or the reverse Y feature or both are used, the alignment of the
color filter to the image remains Bayer GR. The camera includes a mechanism that keeps the filter
alignment constant when these features are used.
For more information about the AOI feature, see Section 7.10 on page 141.
For more information about the reverse X and reverse Y features, see Section 7.12 on page 150.
