Bayer Format
When you set the Pixel Format parameter to any Bayer Format in the color camera, the bits of pixel data will
be reordered to bytes, and then will be stored in the frame buffer in the same way as Mono Format.
For example, if you set the Pixel Format parameter to Bayer GR 10 Packed, the pixel data will be reordered
and stored in the frame buffer as shown in the Figure 9.21. 10 least significant bits of green data will be stored in
Byte 0 and Byte 1, and 10 most significant bits of red data will be stored in Byte 2 and Byte 1. The bit order is
shown in the first figure below. After saving 1 - horizontal line of G-R pattern pixel data, 2 – horizontal line of B-G
pattern pixel data will be stored as shown in the second figure below. G-R pattern (Horizontal Direction) and B-G
pattern (Horizontal Direction) pixel data will be stored repeatedly as a line (Vertical Direction).
