11.3.2 Bayer RG 8 Format (Equivalent to DCAM Raw 8)
When a color camera is set for the Bayer RG 8 pixel data format, it outputs 8 bits of data per pixel
and the pixel data is not processed or interpolated in any way. So, for each pixel covered with a red
lens, you get 8 bits of red data. For each pixel covered with a green lens, you get 8 bits of green
data. And for each pixel covered with a blue lens, you get 8 bits of blue data. (This type of pixel data
is sometimes referred to as "raw" output.)
The "RG" in the name Bayer RG 8 refers to the alignment of the colors in the Bayer filter to the pixels
in the acquired images. For even lines in the images, pixel one will be red, pixel two will be green,
pixel three will be red, pixel four will be green, etc. For odd lines in the images, pixel one will be
green, pixel two will be blue, pixel three will be green, pixel four will be blue, etc.
For more information about the Bayer filter, see Section 11.3.1 on page 205.
The tables below describe how the data for the even lines and for the odd lines of a received frame
will be ordered in the image buffer in your PC when the camera is set for Bayer RG 8 output.
The following standards are used in the tables:
P
0
= the first pixel transmitted by the camera for a line
P
n
= the last pixel transmitted by the camera a line
B
0
= the first byte of data for a line
B
m
= the last byte of data for a line
