20 These four pixel formats are raw sRGB / Bayer 20 These four pixel formats are raw sRGB / Bayer formats with 8 bits per
21 sample. Each sample is stored in a byte. Each 21 sample. Each sample is stored in a byte. Each n-pixel row contains n/2
22 green samples and n/2 blue or red samples, wit 22 green samples and n/2 blue or red samples, with alternating red and
23 blue rows. They are conventionally described a 23 blue rows. They are conventionally described as GRGR... BGBG...,
24 RGRG... GBGB..., etc. Below is an example of a 24 RGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR8 image:
